Behind The Shed
by Cphucker©

Chapter 1

"You're sure about this?" I asked hesitantly, crouching next to my younger sister behind our shed in the backyard.

"Positive," Bree said, fidgeting nervously next to me.

We were both eagerly watching and waiting. Our older sister, Marie, came around the corner just then, in her running outfit on the way back from her normal morning jog. She was a fitness buff, always had been. And her body showed it of course. She was the tallest of the three of us, with a very thin frame and long blonde hair. Her skin had a nice tan to it, from all the running she did. She was always outside it seemed, doing something to keep active.

"Here she comes," Bree whispered.

We were hidden from view, but could easily watch as Marie rounded the corner of our yard and ran into the backyard. She slowed her pace and came to a halt at the back patio, catching her breath and then stretching her legs after her two mile trek. I couldn't help but notice as she stretched that her body was really amazing. Even though she had a thin frame, she wasn't exactly lanky. Her butt especially was really toned and nicely shaped, and even though her breasts were small they seemed to fit her body very nicely. Overall, she was a very sexy young woman.

After stretching for a bit, she seemed to glance around to make sure no one was looking. Thankfully, Bree had suggested this particular spot because it wasn't very visible. There was a tree between us and the patio, and unless you were specifically looking past it, you wouldn't notice the shed or anyone hiding behind it. Marie went around to the side of the patio that was actually a bit closer to us now, and for some reason she leaned up against the house there and just waited for a moment.

I still wasn't sure what Bree had dragged me out here to see. She came to me the other day and said she wanted me to see something. She wouldn't tell me what it was, but she said I had to see it to believe it. Bree and I were a bit closer than either of us were to Marie, being as she was the oldest. Not that any of us didn't get along. Marie was two years older than me, and Bree and I were less than a year apart. I guess naturally we just seemed to have more in common. We had been in the same grade all through school even. Marie was the typical older sister, kind of bossy but also protective of us when we were younger.

"Don't say or do anything when it happens," Bree warned me.

"When what happens?" I asked.

"Sssshhh," was her only response.

I moved closer so I could see better, and ended up rubbing my crotch right up against Bree's shoulder. She didn't say anything, and I didn't think much of it because it wasn't like I was going to get aroused and start poking her. I was just trying to get a better view of whatever she was here to show me.

Marie started to rub at her stomach, and for a moment I thought maybe she was sick. But as I watched in disbelief, she starting to pulled down her running shorts right there in the yard and revealed to us both that she wasn't wearing anything beneath them. My mouth dropped open, but I kept quiet like Bree had said. What in the hell was Marie doing in our backyard out in the open?

"Just watch," Bree whispered. "It gets better."

Marie left her running shorts down around her knees, and even from this distance I could see that she shaved her pussy completely bare. I couldn't believe she would be so brave out in the open like this. Was she an exhibitionist or something? I kept glancing around, nervous for her that someone would be able to see her. But in the spot she had picked, none of the windows of our house were within view. And because of our trees in the backyard, none of the neighbors would be able to spot her either. She had found a spot in our yard that was completely invisible to anyone not standing near there. I guess since our parents were at work this time of day, and my sister and I were typically in school too, she wasn't worried about someone coming to catch her in this little sexual escapade of hers. But since Bree and I had already graduated this year, she either wasn't accounting for our presence or she figured we wouldn't be bothered to spy on her.

Somehow Bree had discovered what she was up to. I wondered how long this had been going on exactly. Marie closed her eyes and started rubbing at her pussy, taking her time and quite obviously enjoying herself. Once I got past the initial shock of it all, my fascination with the whole scene took over and I started to get aroused.

"Hey!" Bree hissed, nudging her shoulder against me. "Ew, Kevin. Gross!"

I had started to get hard in my shorts, and ended up poking her with my dick. I couldn't back off of her without making too much sound though, and neither of us wanted to be caught.

"Sorry, but I can't move now," I said. I was only a little embarrassed, since Bree had caught me masturbating before. A couple of times actually.

"Just, try not to hump me ok?"

We both sat there like that, watching as our big sister masturbated in the back yard in her own little private seclusion. Why didn't she just do that in the house, in the bathroom or her bedroom? She must get off on being outside, or maybe the thrill of being caught was part of it. I'm sure that thrill didn't include her siblings finding her like that. But it did make me wonder what other kinks she was into. I never thought of Marie even having sex. She rarely dated, and was usually so uptight about everything else that I just assumed she was a prude. I guess I was wrong.

I had to admit, it was odd that my erection was pressing up against Bree, and that she wasn't freaked out by it. I couldn't keep it from tensing up a few times, and I know she noticed it. But she didn't say anything, we just watched as our sister quietly masturbated for a few minutes until she whimpered and thrust her hips forward a bit, slowing her fingers on her clit and dropping her head down in pleasure. She really seemed to enjoy her climax, and rubbed at her mound slowly and firmly for a bit more as the feeling washed over her.

Wow, that was really hot! And thinking about Bree watching her at least one other time was also arousing, though I wasn't sure why. These were my sisters, after all. This kind of thing wasn't exactly proper.

Marie pulled her running shorts back up and dashed off into the house, as if those few minutes of sexual pleasure never happened. After she was gone, Bree looked up at me with a mischievous smile.

"So, what did you think?" she asked.

"I can't believe it!" I answered truthfully. "How often does she do this?"

Bree moved away from me a bit, finally withdrawing herself from my erection pressing against her. But she didn't say or do anything to suggest she was grossed out by it anymore. I was still tenting quite obviously between us still, but she pretended she didn't notice. At least, for the moment.

"She's done it the last three days," Bree said. "I caught her doing it last week, and I've been coming out here to watch ever since. I figured you'd wanna see it for yourself."

"I can't believe she does that," I said. I absently squeezed at my boner beneath my shorts, forgetting for a moment that my own sister was standing next to me. My mind was still on the scene we had just watched.

Bree glanced down to see me do it, and then giggled. "A little too much to handle, huh? Perv."

I blushed. "Hey, you're the one who's been spying on your own sister masturbating."

She nodded. "Yeah, I don't know why, but it's really hot. I'm not into girls or anything, and especially not Miss Perfect, but it's fun to know we have this on her, isn't it?"

I shrugged. "Yeah, but if she ever found out we were watching her, she'd freak."

"Oh, of course," Bree agreed. "I'd never tell her. Or anyone besides you. I'd suggest you don't tell anyone either, even your stupid friends."

I was still squeezing my boner through my shorts, feeling way more aroused than I should've been considering how inappropriate this all was. Or maybe, that was why I was so aroused. Bree just stared at me as I did it, and I couldn't look her in the eye. I wanted to move, but she was in my way.

"Are you..." she began. "You're gonna go jerk off, aren't you?"

I was so embarrassed, my erection should have been non-existent. But this whole situation was somehow really sexy, and I felt ashamed that my own sister was here to see it. Of course, was this any different than us spying on Marie playing with herself? The whole thing was really confusing, but apparently really hot.

"It's ok..." She seemed to hesitate to say the words, like she knew it was normal to masturbate but since this was her own brother she was talking to, it seemed wrong to admit it. "I mean, we all do it, right?"

I finally looked at her, and she seemed just as nervous as I was. But there was something else too. Something...perverse in her eyes. Her jaw cocked to the side just a bit, and I could tell something naughty was bouncing around in her head. I knew that look of hers, but had never associated it with sex before.

"What?" I asked.

She let a smile creep across her mouth, but was quick to hide it. "Uh, nothing. Just..."

"Just what?" Shifting the focus onto her seemed to ease my nervousness, and embarrassment.

Bree fidgeted, standing only a few inches from her aroused brother with his dick tenting out in his shorts. Her manner when she got like this, playful and devious, drove me wild. I only secretly admitted to myself that I was attracted to Bree. She was shorter than me, with reddish blonde hair and the cutest freckles dotting her button nose. When her full lips would purse into that devilish smile, it just got to me I guess. And her eyes would say more about what she was thinking than any other part of her, even that cute mouth.

And, her body was nothing to scoff at. She was thin like Marie, but with just a bit more curves to her. Marie was like a stretched out version of her, with less ass and chest. Bree had a nice set of C cups, more than decent for her tiny frame, and her butt was perfectly round and taut.

"Are you?" she repeated.

I just eyed her, cautious yet not entirely put off by the thought of telling my hot younger sister that I was going to go upstairs to my room and pull on my wiener until white stuff came out.

"Maybe," I said finally.

"Well, isn't turnabout fair play?" she said, with that sexy little grin.

"You want to watch me," I said, "because we watched Marie?"

She nodded, turning red but not averting her eyes from me. She waited, obviously teasing me. But for some reason, it made me want to show her up. And besides, she had seen my dick before.

"Fine, you little twerp." I yanked my shorts down and let my cock spring free.

Her eyes widened, but she didn't point and laugh or even get all embarrassed. Her smile faded and she just stared openly at my penis. I could tell that she was aroused by it, and that made it lurch.

"But you better give me a show too," I said.

Bree looked up at me finally, and then glanced around. "I don't know if I could do it here. I don't...get off the same way Marie does. I have to be laying down."

"Fine, but you owe me," I said, and grabbed my dick firmly.

So there we both stood, both of us watching my dick as I jerked it. Bree was positively entranced by the sight, and I found myself sneaking glances of her while I beat off. It was sexy, there was no doubt, to be doing this while a cute girl watched. And the memory of seeing Marie touching herself was still vivid in my memory. Both of those images seemed to get me there much sooner than I anticipated. I slowed in my movements, not wanting to bust right away.

"What?" Bree said, her voice raspy. "Why did you stop?"

I grunted. "I...was about to cum."

She looked up at me and shook her head. "Good, do it!"

I guess I was embarrassed about it, but it seemed silly considering. For some reason though, cumming in front of her seemed to add finality to this naughty act, and when it was all over we both might feel bad about it. The forbidden aspect of being brother and sister had spurred me on before, but now it hindered me from wanting to finish.

"Do you want to cum in my hands?" Bree asked.

I pictured jerking my big cock off into her little hands cupped and held out to catch my sperm. The mental picture was just too much, and I quickly beat myself off again. She took that as a yes, and held up her hands just as I pictured she would.

"Ugh!" I grunted, and felt my balls churn. I aimed my dick carefully, not wanting to shoot off all over her, and let it cum.

It didn't happen exactly as I had pictured, with my dick calmly spouting gentle streams of semen into a nice neat little puddle in Bree's palms. Instead, I exploded up her arm on the first shot, and the second tagged her t-shirt on the edge of her breast. The rest of my spewing was easier to maintain, but I fired off six or seven powerful spurts, and it felt better than anything I had ever felt before. Bree excitedly tried to keep from moving, even though I had painted her hands and arms. She just held them up, waiting for me to finish.

When I finally was, I lost all sense of embarrassment or shame. It was the opposite of what I had feared. Now that it was over, it felt good to be sharing this intimate part of myself with her. She smiled as she examined the mess I had made, and I squeezed my dick and sighed.

"Wow, you came a lot," she said.

"Yeah, sorry. I tried to keep it all in your hands."

"That's ok, it was so hot!" She seemed enthralled with my cum all over her.

"You better go wash up," I said, stuffing my still-hard penis back into my shorts.

She nodded. "Hey, um, how often do you do that?"

"Every day," I answered truthfully. "Why?"

"Well..." She seemed to be hesitating to ask what she really wanted to. "That was really cool, is all."

I could sense that she had been excited by this naughty little escapade. And maybe she would want to repeat it, I hoped.

"Want me to tell you when I do it again?" I ventured.

It could have been a risky question, if in fact she regretted all this. But my instincts hadn't failed me. She nodded enthusiastically.

"Yeah, is that ok? I mean, you liked it, right?"

"It was awesome," I assured her. "And you still owe me."

She really lit up at hearing that. "That's right! I do! I'll give you a great show later tonight, ok?"

Later tonight, our parents would be home and we wouldn't have much privacy. I couldn't just be seen going into her room and locking the door, or vice versa. They, and Marie too, would be suspicious.

"I don't know..." I was reluctant now, even though the thought made me stay hard in my shorts.

"Please!" Bree begged, like a little girl asking for candy. "We can wait until everyone is asleep."

"Ok, but we have to be careful."

She clapped her hands. "Thanks, Kevin!"

She trotted off, still covered in my cum, and went to get the hose. I just stood there for a moment, wondering if we could really get away with this. Staring at her cute little body as she washed herself made me forget most of my fears. And, there was still the matter of Marie. Bree and I could keep coming out here to watch her, and maybe I could even get off at the same time. Watching Marie and being watched by Bree was really hot to think about.

I quickly went inside to my room, where I took a cold shower to keep from jerking off again.

Chapter 2

That night couldn't come quick enough. Once everyone went to bed, I waited in my room until it was well after midnight. Then I tiptoed down the hallway to Bree's room and quietly opened her door. Her light was off, and it looked like she was asleep. But when I approached, I could see her turn her head toward me.

"Kevin?" she whispered.

"Hey." I closed the door behind me and approached her bed.

She sat up, looking excited even in the dark. "We have to be quiet, Marie will hear us through the wall."

My sisters shared a wall between them, and it just so happened that their beds were parallel too. Bree was right, if there was squeaking or lots of groans, Marie might hear.

"So, what are we gonna do then?" I asked.

Marie thought for a moment, biting her finger nervously. "Um, I promised you a show, so I guess I'll get naked."

It was dark but not too dark to see as Bree took her camisole off and then slid her pajama pants down past her ankles. Without hesitation, she had stripped completely naked before me, and I could see everything. I guess that was the point. Her tits looked awesome, better than I imagined they would. Her pussy wasn't bare like Marie's had been, but it was neatly trimmed.

"What should I do?" she asked, seeing me eyeing her body up and down and not trying to hide anything from me. She apparently liked that I was so attracted to her.

"Should we...do it together?" I asked, realizing I hadn't planned what to do before coming here.

"Sure." She seemed fine with that, eager actually. "Come sit next to me then."

I pulled my shorts off and joined her. We were both naked on her bed now, and even though it seemed a little weird, it was mostly just hot as hell. I was at full mast already, and Bree noticed. She eyed my dick, and her hand drifted down to her crotch.

"Go ahead," she encouraged. "Just do whatever you want."

I grabbed my dick and slowly started stroking it. It would have been better with the light on, but someone might notice. I had to settle for how it was right now, and even so it was hotter than anything I had ever seen online or in person.

Bree's tits bounced just a bit as she began rubbing her clit in a more purposeful motion. She didn't really start out slow like I was doing. She seemed to get right to business. Our legs were touching as we both laid there, eventually settling into our normal individual routines for this kind of thing and just doing what came natural. It felt really good to be this open with a girl, and to let her see this side of me. I had never ever masturbated in front of anyone, except for her earlier today. It was intimate in a strange way that seemed better because we were close siblings.

Bree climaxed very soon, long before I would even get close. She whined softly, and her hips came off the bed a bit. She humped into her hand and her eyes were closed tight as she rode it out. I kept stroking as I watched her, but it would be a good while longer before I was ready to blow. She relaxed and opened her eyes, sheepishly looking over at me but not missing a beat as she went right back to rubbing her cunt.

"That felt good," she breathed.

"It looked like it," I responded. "You cum quick."

"I was really horny," she admitted with a smile.

That seemed to get me off even more than the visuals of my cute sister masturbating. Knowing my cute sister got off on seeing me masturbate was really arousing. I jerked faster and gently rubbed under my balls as I did so.

"Where do you usually cum?" she asked me, more focused on me now than herself.

"On my stomach," I said, huffing a bit. "Depends on where I'm doing it."

"Where are all the places you've cum?" She was very interested now.

"On myself, a kleenex, trash bin, an old shirt, the toilet, the sink..." The list went on and on, but that seemed to be sufficient to satisfy her curiosity.

"Wow," she said, and she put two fingers into her pussy just then. "I can only cum when I'm stretched out and totally relaxed."

"You just need to practice," I said, really getting into my jacking.

She noticed, and she started grunting a bit as she fingered herself more urgently. We were both getting there, and knowing that only fueled us both.

"I...do it a lot," she said, starting to pant. "Almost every day."

"Mmm...well, maybe...uuuhh...you should try it in different places."

"Like where?" Her hips thrust upwards, like she was really close.

"Let's try it again tomorrow," I said, feeling my balls tighten. "We'll watch Marie, and do it behind the shed again."

She cried out just then, a bit too loud I thought, and climaxed again. I squinted as my dick started spewing all over myself. She noticed as her own orgasm finished, and she beamed brightly at seeing my torso covered in streams of white.

"That is so cool!" she whispered.

I smiled, and breathed a sigh of relief. That had felt good, even better than before. And, I came a lot even though I had drained myself already today. I just kept stroking, letting the good feelings trickle throughout my body. Bree absently rubbed her mound and stared at my dripping cock as I touched it.

"We need to do this again," I said. "Like, as often as possible."

"I agree," she chuckled. "It feels way better when someone watches you."

Suddenly, our legs touching seemed like it was too tempting, and I moved to get off the bed. I wasn't embarrassed or regretful, it just seemed like it would be easy to cross another line that we weren't ready to cross. Bree didn't object, and I think she just thought I was ready to go to bed.

"Thanks," she said. "Remember, eight o'clock tomorrow. Set your alarm."

"I will." I left her room and returned to my own, barely remembering to grab my discarded shorts on the way out.

I slept really well that night, but my dick was pointing at the ceiling the entire time.

Chapter 3

"Sssshhh," Bree hissed at me as I approached. "I think she's coming back already."

I hurried to hide with her behind the shed, and this time our bodies pressing up against each other didn't bother her. We quietly observed our older sister Marie return from her jog, just like yesterday, and find her secret little spot after stretching her legs.

I started to loosen my shorts, and Bree seemed amused.

"Already?" she whispered.

"Come on, you need to try it," I replied.

She was reluctant, but remembered what we had agreed. She would try to masturbate in places other than her bed. She reached into her own shorts and started fingering herself, though she left them pulled up.

We both watched as Marie did her usual routine, pulling her running shorts down to her knees and rubbing her slick cunt for a good few minutes before having a nice orgasm. This time though, she didn't seemed content with just one. Even though it had been obvious she had climaxed, she kept rubbing. From her reactions to her own fingers, I could tell she was more sensitive now. Maybe the second one would be even better.

"Oh my god," Bree whispered so quietly that I barely heard her. "She's so horny."

I grunted, and had to stop jerking myself to keep from spewing prematurely. Bree noticed, just like before, and this time took that to mean she needed to catch up. Either that, or the thought that I was close was getting her off even more.

She started grunting, making small sexual noises, until her hand suddenly stopped her frantic movements and slowed to a crawl. She seemed to have a hard time staying in place as she crouched beneath me, and I could finally see that she was having an orgasm.

I was proud of her, and simultaneously aroused to the point of no return. I started cumming, and wasn't entirely aware of where I was about to shoot. I splashed a stream of white across her hair accidentally, and managed to pivot to shoot the rest onto the side of the shed. I don't think Bree was even aware of what had happened, she was so lost in her own pleasure.

Marie finished getting to her own orgasm, again, and seemed satisfied now. She pulled her running shorts up, and my attention turned to Bree fully now. She was still crouched below me, but was feeling cautiously at her hair.

"Kevin!" she said. "Oh my god, really?"

"Sorry." I didn't bother to stuff my dick back in my shorts, and just watched as she tried to peel the stream of cum from her hair.

Realizing it was a lost cause, she yanked her t-shirt over her head, and to my surprise she had no bra on underneath. She was bare-chested and using the shirt to clean up the mess I had made. It must have looked really funny to see me with my dick hanging out, and her rubbing the shirt on her head with her tits hanging free.

Funny, or shocking. I could easily tell which one Marie thought it was, when she suddenly appeared right in front of us next to the shed with wide eyes.

"Kevin!" she exclaimed, then she turned to Bree. "Bree?!"

We both froze, and just stared back at Marie. She was still in her running outfit. She must have heard us before going inside. Crap, we were totally busted now. And we couldn't have been in a more awkward position.

"What the hell?" she yelled.

Bree quickly covered herself with her soiled shirt, and her hair was a comical mess. But no one was laughing right now.

"Uh, shit..." She stammered to explain. She kept glancing from Marie to me and back, but I had nothing to add. I was so dumbfounded I didn't even put my dick away. I just held it there, dripping a string of cum from the tip. It was obvious by the splatter next to me on the shed what I had just done.

"What are you two doing?" Marie demanded.

"We were..." Bree was really struggling to come up with something.

"Were you two spying on me?" Marie said, her voice full of shock and embarrassment.

We just stared back at her, our deer-in-the-headlights look answering her question. I suppose my dick and Bree's tits told the rest of the story. Maybe Marie thought we got so aroused by our voyeurism that we started in on each other. She probably wouldn't have guessed that we were just playing with ourselves and not touching each other at all. I felt like reassuring her that this would be the correct assumption.

"Yes, we were," came my response finally. Bree shot me a look.

Marie was flabbergasted. "I can't believe you two! Are you...having sex?"

Bree shook her head in protest. "No, Marie! Honest!"

I finally got the courage to pull my pants back up and face my older sister like a man.

"We didn't touch each other," I agreed. "We were spying on you, it's true. We just got so aroused by it that we couldn't help ourselves. It's my fault, Bree was just playing along."

Marie was so angry that she couldn't even get her words out right. She just shot another glaring look at Bree, and ran off into the house.

When it was just the two of us again, Bree gave me a look of terror.

"Do you think she'll tell Mom and Dad?" she asked me.

I shrugged. "If she does, then wouldn't she also have to tell them what she was doing?"

Bree seemed relieved at this realization. "Yeah, you're right. She wouldn't want them to know what little Miss Perfect does in the backyard."

She put her shirt back on, and I got a good look at her tits again before they were covered. Her shirt had a big stain across the arm now, where she had wiped at her hair.

"I'm...gonna take a shower," she said, and made to leave.

"Wait." I grabbed her arm to stop her. "What about...us? Are we ok?"

She smiled. "Yeah, don't worry. We probably won't be able to do this again, since I doubt Marie will ever be playing with herself in the backyard after this. But we can still play."

She winked at me, and ran off inside. I stayed there for a few moments, trying to compose myself. I wondered what was in store for us now with Marie...

Chapter 4

Dinner that night was, well, very awkward to say the least. Marie was fuming, but didn't say a word to anyone while we ate. Mom and Dad mostly talked between themselves, not involving us kids much in the conversation. Bree and I must have looked as guilty as we felt, and Marie was staring icy daggers into us both. But, like we had guessed, she didn't squeal on us. That would have meant squealing on herself, and as much as she probably wanted us both to suffer, she didn't want to look bad either.

Afterward, Bree and I went into the living room to watch TV, while Mom and Dad said something about going to bed early. That usually meant they were going to have sex, which we couldn't care less about really. Marie took this as her opportunity to confront us.

"Both of you," she said, standing between the kitchen and living room in her camisole and pajama pants. She must have changed clothes just moments ago, which was a bit strange. "In the basement, now."

Bree and I exchanged looks, and Marie didn't wait for us to respond. She turned and headed downstairs to the basement, and we were helpless to refuse her. Better to get this over with than to keep feeling guilty and avoid her.

We trotted off after our big sister and the three of us were now face to face in the basement. It was mostly finished, with carpet and an old couch and some bean bags. Best of all, it was the bottom of three levels in our house, with all the bedrooms upstairs, so it was totally private when Mom and Dad were upstairs getting it on.

Marie sat on the couch cross-legged, while Bree and I each took a bean bag chair. She eyed us carefully, but she seemed to have calmed down quite a bit. Neither Bree or I could look her in the eye, though.

"Ok, look," Marie began. "We all know that none of us should have been doing...that, outside in front of each other."

Bree sheepishly nodded, and I just sat there saying nothing.

"It was wrong of you two to spy on me," she continued, "and I'm very embarrassed to have been caught. But, I feel like since we all share some of the blame, we should just come clean, and I should explain why I was out there in the first place."

Bree seemed to light up a bit, and chanced looking up at her big sister. I just watched Bree, waiting for her to respond positively so I could then attempt to look Marie in the eye.

"We all...masturbate, right?" Marie asked, and waited for us both to respond. Bree nodded, and I did as well. "Good, there's nothing wrong with that. It's not a big deal that we all do it. It's a private matter, and it doesn't hurt anyone."

"Why were you doing it outside?" Bree blurted out, not waiting for Marie to finish her explanation.

Marie's nostrils flared, but she didn't lash out. "It's kind of embarrassing, but I guess I should explain so you don't think I'm a pervert or anything. A while ago, after my run, I came home and took a hot bath because I was so exhausted, more than usual because I went farther than I normally do. I started to...touch myself, and of course ended up...well, finishing the act. And I noticed that when I...ahem, arrived so to speak, it was better than normal. I just thought maybe it was the hot bath. So I took another one the next day, and...masturbated then too. But it didn't happen again."

It was bizarre to hear Marie talking about this, and saying those words. I found myself getting aroused, but I wasn't about to let either of my sisters see my shorts tenting.

"So," Marie continued, "the next time I did a particularly exhausting run, I took a shower and ended up using the shower head on...myself. And again, it was a really good...orgasm. Ahem. So I did the same thing the next day, including the run, and it was really good again. If my run wasn't very long, or if I didn't run at all, then my orgasms weren't as good. I realized that it must be the adrenalin from my intense runs that was making it so good. And the closer to the end of my runs I did...it, the better they seemed."

"So you're an adrenalin junkie," Bree said. I just kept quiet, but I was very interested.

"So to speak, I guess," Marie replied. "Lately, I've been trying to figure out when they are the most intense, and it does seem that right after my run they are really good. So I found a spot that I thought was private in the yard and I kept doing it."

"But, why do it outside?" I finally spoke up.

Marie seemed uncomfortable, but didn't dismiss my question. "Yes, well I suppose you deserve to know why I do that, even though I should just be mad at you both. But I guess I was just asking to get caught eventually. The truth is, I do find it kind of arousing to do that outside. I don't want to be caught, but the thrill is a little exciting. And when I'm really excited, mixed with the adrenalin, my orgasms are even better."

"We noticed," Bree said. "You did it twice in a row today."

Marie shot Bree a look, but again, how could she really be mad at us? She was the one who was acting deviantly. But Bree and I masturbating together while we spied on her, though, was a different matter. And one Marie chose to bring up finally.

"Now that I've explained myself," she said, crossing her arms, "now it's your turn. Both of you. What exactly is going on between you? I can't believe you'd both be masturbating together behind the shed unless there was already something going on."

Bree shook her head. "We aren't screwing, Marie. Honest."

Marie looked at me, waiting for me to agree. I nodded enthusiastically.

"It's true, we don't touch each other. We just masturbate."

Marie carefully eyed both of us, but seemed satisfied with our answer. She believed us, and now the tension in the air between all of us could clear.

"Fine, I believe you." She paused. "We've all walked in on you enough times, Kevin. And Bree, I know how horny you can be."

I was appalled that she had ever caught me, since I never knew it. I wondered how many times she had seen me jerking off. God knows I had done it in enough places around the house, with people home even.

"So, what now?" Marie asked us. "I don't think it's fair to say that none of us can masturbate anymore, obviously. I can find other ways to...experiment, but I don't want it being awkward every time I go for a run, with you two knowing what I'll be doing as soon as I get home."

"It's not a big deal, Marie," Bree said. "We don't care if you masturbate. Hell, all of us do it."

"Sometimes together, I gather," Marie countered.

Bree's eyes seemed to light up suddenly, as if she had just had an epiphany.

"Hey!" she exclaimed. "Let's all do it together!"

For some reason, my eyes shot toward Marie and she was looking right back at me. We both blushed, and I was still rock hard in my shorts.

"I...don't think that's a good idea," Marie said.

"No, seriously!" Bree continued. "Marie, it feels sooo much better when you do it with other people. Imagine how good it would be after your run if we were all watching you, and doing it with you."

Marie actually seemed to ponder that thought. She did get off on the possibility of getting caught, which was really just a form of exhibitionism. And she could actually live that fantasy out by knowing we were watching her. As long as she wasn't put off by the incestuous overtones of all this. Bree was a horny little devil, so of course she didn't care. Marie was more mature and less spontaneous. It might be a stretch to-

"Ok, fine." Marie's simple statement caught me off guard.

"Yay!" Bree said, clapping her hands. "It'll be so much fun."

Now I wasn't hiding my erection anymore. I laid back as I processed what Marie was agreeing to, and ended up letting my tent out into their view. Marie's eyes widened, but she didn't say anything. Bree looked over at where she was staring, and just kept smiling.

"He has a really big cock, Marie," Bree said. "And he cums a lot."

Marie just stared at me, and I didn't move to cover myself up. Why? At this point, we were basically all going to see each other naked and at our most vulnerable. There was no reason to hide from each other now.

"I'll take your word on that last part," Marie said, "but I can see the first part for myself."

I smiled, feeling like that was her way of paying me a compliment.

"Can we do it right now?" Bree asked, practically peeling her clothes off already.

Marie glanced up, picturing Mom and Dad upstairs. "I guess we could. They won't hear us down here."

Bree was naked in seconds, and Marie slowly pulled at her pajama pants. I didn't want her to feel awkward, so I discarded my clothes like it was no big deal. She was watching me the whole time, and when my cock came into view, she finally got her pants off and sat on the couch with just her camisole on. Bree and I waited for her to finish stripping, and she blushed deep. But, she was never one to back down. So she pulled her top over her head and set it aside. Now all three of us were naked together. A few feet apart, and not touching anyone but ourselves. We weren't doing anything "wrong" at this point, we probably all told ourselves.

"Do you just..." Marie seemed to have a hard time getting comfortable.

"Just do whatever you normally do," Bree said, and spread her legs shamelessly. "We've seen you do it already, so it's no big deal."

It wasn't until I started stroking that Marie finally reached for her crotch. But she was still sitting cross-legged, hiding her goods from our view. Bree was quick to catch on.

"No hiding," she scolded. "It's more exciting when the other person can see everything. Don't be embarrassed. We know you have an awesome body, and that you shave."

Normally all of those little details might have made Marie more embarrassed, but in this setting they seemed to help. I figured Bree knew what she was doing, and just kept quiet while I stroked off. Marie nodded and leaned back, spreading her legs and showing us both her pussy. It looked really nice, and I could even see her little butthole too. She really did have a good body, lean and sexy. I stared at her pretty much the whole time, even though both of them were staring at me mostly. Still, I caught Bree eyeing Marie for some of the time, making me wonder if she was into girls even just a little.

The three of us eventually worked ourselves into a huffing circle of rapidly moving arms. Marie really took off on herself once we were all doing it. None of us were ashamed of our bodies, and weren't embarrassed that other people were watching us do our most private act. I loved seeing both my sisters stare at my penis with a look of desire in their eyes. This was great, and I kept up a nice medium pace so as not to blow too early.

Bree was the first one to pop. She cried out and thrust her hips up off the bean bag, rubbing her mound firmly in circles. It was really hot to see her cum, and even Marie must have thought so, because she grimaced and looked to be ready to go herself. I really wanted her to have fun this first time, so I quickened my own pace and hurried myself to the edge so she could watch me spew. I groaned loudly, so they both knew what was happening, and then started to fire off while they watched.

It was really hot to have just Bree watch me cum, but having them both was even better. My balls tightened and drew up beneath my shaft, and semen shot out of the tip and tagged my chest on the first shot. I painted lines across my torso, seven or eight of them, before dribbling out the last bit into my belly button. I enjoyed it immensely, but was sure to watch Marie as she rubbed at her cunt while she stared on at the show.

Finally, her eyes closed tightly and she made a really sexy grunting sound that I didn't remember from before when we spied on her. She whimpered a lot like Bree, and threw her head back as her orgasm tore through her. She reached up with her free hand and grasped her breast, which I thought was the sexiest thing I had ever seen before. When it was over, she looked positively glowing and satisfied. Bree was still happily rubbing as she watched, but she wasn't trying to cum again. She was just enjoying herself.

"Awesome!" Bree said when it was obvious Marie was finished. "How was it?"

Marie had to catch her breath for a moment. "It was really good, I admit. You were right, watching and being watched make it better."

"Better than the adrenalin?" Bree asked, smiling.

"I don't know, we'll have to try." Marie smiled, especially at me. I think she really got off on seeing a nice big cock explode.

"We did it together last night too," Bree said. "If you ever want to join us..."

I nodded, hoping she would. "We don't do anything different, just masturbating."

She seemed to be thinking it over. The fact that we were all still naked, completely content and openly exposed to each other, seemed to help make it not so weird.

"Maybe," Marie said, still reluctant. "We'll see. I don't usually cum more than once a day."

"Really?" Bree seemed truly surprised. "Ever since I started watching you, I've been cumming at least twice. Sometimes three or four."

I couldn't believe Bree admitted to that, but it wasn't out of character. Like Marie had said, she was a horny little thing.

"I probably don't want to know how long you've been watching me," Marie said, reaching for her clothes. "But it doesn't bother me anymore, so it's fine. I guess I should be flattered."

"We really just liked watching," I said, hoping it would help. "You're so beautiful, especially when you're doing that."

She blushed, and winked back at me. "I would like to see more of that monstrous thing. Even if we don't do it every day, maybe we could try to do it together once in a while."

Bree nodded. "Yeah, that would be cool!"

I nodded too. "Definitely."

We ended up all getting ready for bed, and none of us did anything else together that night. I jerked off in bed but didn't cum. For some reason, I wanted to save it for my sisters. I planned on doing it as much as possible with them. I knew Bree would always make herself available. And I hoped Marie would be just as open. I couldn't imagine anything hotter than what had just happened tonight.

Then again, I also knew myself. And Bree. She was just as adventurous as me. Maybe, we could go even further...

Chapter 5

Things had...progressed, shall we say, since that first time behind the shed with Bree.

She was kneeling in front of me in my room, late at night after everyone else was asleep, and I was beating off furiously mere inches from her face. She was watching my hand move up and down my cock and licking her lips eagerly as she rubbed at her mound. She had already climaxed, but she usually went two or three times per session.

I grunted finally. "...Ok."

She closed her eyes and smiled dreamily, knowing what was about to happen. She kept rubbing her clit, but her focus was on my cock as I aimed it at her face. Within moments, I felt that wonderful tingling sensation in my balls as the cum started to flow up my shaft. Then with a sharp spike of pleasure, I released a torrent of semen across Bree's cute face, painting a thick line from her chin up to her forehead.

"Ugh..." I breathed as I kept releasing lines across her face. She just smiled, enjoying the feel of my warm sperm coating her cheeks and nose and mouth. I jerked the last few drops out over her chin, and even inadvertently touched her lips with the tip of my cock. Her tongue was so close to snaking out and licking me, but she held off going that far.

When I was finished spewing, I stepped back and admired the beauty of my sister's cum-covered features. I squeezed my cock and smiled.

"That was good," I said.

She opened her eyes, carefully at first so as not to get any cum in them, and then beamed at me.

"It's so fucking sexy," was her reply.

She furiously rubbed at her mound now, planning to get off one last time. She always did that, waiting until I had cum on her face or tits or anywhere on her body, and then having one last orgasm with that extra thrill. Her face contorted and she grimaced within moments, grinding her hips against her hand and enjoying the sensation of her climax while she rubbed at her clit.

I never got tired of watching her do that, and I absently jerked my cock while I observed. When she was done, she hopped to her feet and made to leave my room. She glanced back at me one last time.

"Thanks!" she said with a wink, and then went back to her own room.

I laid back on my bed and sighed, thinking about all that had happened since that first time my sisters and I had all masturbated together in the basement.

After that initial time, when all of us had agreed to do it together as often as possible, Bree and I were nice and reserved at first, for Marie's benefit. We didn't want our older sister to get too freaked out by anything, and just getting her to go along with it had been an accomplishment as far as I was concerned. But when it was just Bree and I, we were pretty wild.

Right off the bat, we thought it would be fun to still go behind the shed when Marie came back from her run. Of course now she knew we were there, "spying" on her. She didn't go to her little hiding place behind the house, she came right over to where we were waiting for her and joined us behind the shed. We all dropped our shorts down to our knees and started rubbing ourselves while we stood in a tight circle. There wasn't much space for all three of us to hide there, so we were bumping elbows and giggling to ourselves. Marie was sweaty and panting anyway, but Bree and I didn't care. It was truthfully a lot of fun, aside from the sexual satisfaction it would bring, to be naughty with each other like this.

Both of them pretty much stared at my cock the whole time, and I got to go back and forth between Bree's cute little bush and Marie's slick shaved cunt. Bree came first, as was becoming the norm, and I was second. I shot off on the ground in front of us as they watched excitedly. Like always, I came a lot. Marie was right behind me, and she groaned and rubbed her mound very slowly as she dragged her climax out.

"How was it?" Bree asked her, referring to her experiment with having an orgasm at the peak of her adrenalin.

Marie nodded. "Good. Really good. It's got me curious though."

"About what?" I asked. We all just stood there with our genitals still exposed, none of us in a hurry to hide our privates.

"Well, each time we add something exciting to our game, it gets better. So I'm wondering what else we can do now."

Bree smiled. "You mean, like first of all being watched, and then the adrenalin, and then doing it together?"

Marie nodded. "What else can we do to make it more exciting?"

"I can cum on you," I blurted out, probably a bit too excitedly.

Both of them seemed surprised, but they didn't object.

"That could be fun," Marie admitted.

Bree nodded enthusiastically. "I think I'd really like that."

"Not all the time," Marie said. "Maybe once in a while. It wouldn't be as exciting if you always came on us."

Bree didn't agree with that, I could tell, but she didn't say anything. I could just cum on her when I wasn't going to cum on Marie.

We all pulled our shorts up and went inside after that.

Later that night, we all ended up in the basement again towards the end of the evening. Marie hadn't been as into it as before. Maybe she was exhausted, or just not as horny as Bree and I. The two of us were eager to get into it. Marie mostly just watched us as we each masturbated. She was rubbing herself but not urgently. Bree, on the other hand, couldn't wait for me to cum on her for the first time.

"On my tits," she said, as she neared her own orgasm.

I nodded, and got close to her while I continued to jerk off. She really liked that I stood close to her, where she could get an even better view of my cock. Marie picked up the pace a little bit, finally working to her own climax with some energy. When I glanced over at her, I could see that her hand seemed to be deep in her crotch, and her legs were hiding her pussy from my view. It almost looked like she was reaching down to something else. I really wanted to see that.

"Marie," I said, getting her attention. "Let us see."

She spread her legs wider without hesitation, obeying my command. To my surprise, it was just what I had suspected. She was touching her ass! She rubbed the pad of her finger against her small pucker, alternating between it and her cunt. It was so hot, I felt the cum rising in me already.

For the first time in a while, I was the first to cum. I looked back to Bree just in time to spew across her chest, which was prominently sticking out to receive my load. Bree purred as I squirted all over her generous tits. Some of it dripped down to her stomach, and some of it dangled from the tips of her nipples. She came hard just as I finished squeezing the last of it out.

Marie was just as close behind, and cried out behind us on the couch as she peaked. We both turned to watch her stick her finger up into her ass to the first knuckle, and with her other hand she stroked her pussy while she rode it out.

"Marie!" Bree exclaimed, after she had finished. "You like it in the butt?"

Marie blushed, and nodded sheepishly. "Yeah, I kinda do. Only once in a while though."

"That is fucking hot!" I said.

"Not as hot as you cumming on Bree," she replied. "I can't wait to feel you do that to me."

Chapter 6

After we had all gone to bed that night, I sat in bed completely awake while thinking about where I would cum on Marie. I probably could've jerked off again, but I didn't want to keep Marie up all night. She had seemed tired when we started up earlier in the basement.

The next day, Bree accompanied Marie on her run. Apparently she had been convinced by her older sister that the adrenalin rush was worth the effort. But Bree wasn't a seasoned runner like Marie was. They took forever coming back, and I waited patiently behind the shed for them.

After about an hour of waiting though, I got worried. I left the shed and waited on our front steps so I could see them even from a ways off. After a little while, I glimpsed two people far off, moving very slowly. Once they got closer, I could see Marie supporting Bree as she limped along. Crap, she had hurt herself.

I hurried to help them, and together Marie and I carried Bree into the house and upstairs to her bedroom. Bree had pulled something in her calf, apparently exerting herself too much trying to keep up with her big sister. Marie went to run a hot bath, and I stayed with Bree.

"God, that was stupid," Bree said, shaking her head. "I'm sorry, bro."

I frowned. "What do you have to be sorry about? It was an accident."

She looked up at me, disappointed. "I ruined our fun behind the shed."

I chuckled. "Hey, don't worry about it. I can still jerk off without you, you know."

She smiled. "Hey, want to cum in the bath water for me?"

We both laughed, since obviously she was joking. But, it did get the wheels turning in my head. Marie came back and we helped Bree undress and then took her into the bathroom. After gently setting her into the hot water, Marie started taking her clothes off too.

"Uh, sorry," Bree said, "but there's not enough room in here for both of us. Besides, we're not four years old anymore."

"There's another shower in the house, dummy," she said, smiling down at her naked little sister. "I'll be back."

She trotted off completely nude downstairs to the other bathroom and we heard the shower turn on. Mom and Dad weren't home, so it was no big deal. Actually, it was kind of nice that Marie felt open enough to do that. We had all seen each other naked plenty by now.

"If you want bro, you can jerk off right here," Bree offered, settling into the tub and getting comfortable. "My leg hurts too bad for me to join you, but I don't mind if you wanna look at my body and do it."

"Thanks but..." It was a very nice offer, and she did look really nice all wet and shiny in the tub. I started to get hard, but somehow it seemed selfish to do that. Bree just looked at me, waiting for me to whip it out and start.

"It's ok," she said, softly. "It would be sexy."

I glanced behind me. "Marie will probably come back in a few minutes."

"You think she'll mind?" Bree asked, eyeing me with a smile. "I'll even let you cum on me."

I gave in and dropped my shorts.

"Get naked with me," Bree suggested.

I complied and stood next to the tub with my dick pointing straight out over her. I grabbed it and started wanking while she watched. She tried to rub at her pussy under the water, but I could tell by her face that her leg just hurt too much to enjoy it.

"Does it hurt bad?" I asked, still jacking off.

She nodded. "Yeah, sorry. I really want to do it with you, but I don't think I can."

I got an idea just then. I sat on the edge of the tub and got as close as possible to her, and resumed masturbating.

"Do you want me to rub your calf?" I offered.

"Um, sure!" Bree said, happy to let me do that.

I stopped jerking my dick and reached into the water as she lifted her leg a bit for me. I grabbed her calf and started working the muscle. She moaned as I did that, and her eyes closed.

"That feels really nice," she said.

My dick was still pointing straight up, but I didn't pay it any attention at the moment. I tried my best to make Bree feel better.

A few minutes later, Marie came back from her shower. Her hair was wet and she was naked, which made her look really sexy, even more than normal. Something about her tight, thin body really got me going. Even though I was usually a tits and ass guy.

"Aww," she said, when she saw what I was doing. "You're such a good brother."

I smiled. "Just trying to help."

Marie walked over and knelt next to me, and stroked Bree's forehead. "Feel better?"

Bree nodded. "Yeah, but there's no way I can cum."

Marie laughed. "Is that all you think about?"

Bree shrugged and got that devilish smile again. "What can I say?"

Marie also saw that my dick was rock hard, and that I was naked now just like them. It was kind of funny how we were all comfortable around each other in our nudity. We had never been this close before, but with all of the masturbation stuff we were doing it just seemed natural. And it felt really nice, especially that I could pop a boner and not only was it not a big deal, it was actually a good thing to them!

"Want me to rub her leg while you jerk off?" Marie offered.

I thought about it for a second. "You're not strong enough to get in deep. You really gotta work the muscles when they cramp up like this."

Marie shrugged. "Then I'm not going to masturbate either. It doesn't feel right, somehow."

"I really don't mind," Bree protested, even though she was pretty much helpless to do anything right now. "You guys don't have to stop for my benefit."

"You know..." I began, but had a really hard time actually saying what was on my mind.

"What?" Marie asked.

I eyed her body again as she knelt in front of me. Her cute little boobs looked really nice right now, and her nipples were poking out. Either she was cold, or more likely she was aroused. Bree would probably be willing to play along with anything I suggested, with the way she seemed to be sympathetic to her siblings' sexual needs.

"One of us could keep rubbing her leg to ease the pain," I said, "and the other person could..."

Marie's eyes widened, but Bree didn't understand.

"What?" she said. "What are you suggesting?"

Marie looked down at her little sister, and I could tell she was seriously mulling it over. There was a conflict in her mind as she considered what I had just suggested, and I could see her resolve melting.

"I guess so," she finally said. "I mean, it would make her feel better."

My dick lurched, but I kept my cool. I couldn't believe this was really going to escalate to us touching each other. My heart was beating faster now.

"What would make me feel better?" Bree insisted, glancing from me to Marie and back.

It might have been kinda rude to ignore her like this, but I didn't answer. Instead I lifted her leg higher, seemingly to give myself a better grip on her calf but really to expose her pussy to Marie. Also, by keeping my hands on Bree's legs, I was telling Marie which part of our naughty little plan I wanted her to perform. She seemed to catch on immediately.

She leaned close to Bree and stroked her face for a moment. "Relax, honey. We just want to make you feel better."

Bree still didn't understand, but she seemed to sense that something big was about to happen. She just swallowed and did as she was told.

For the next few minutes, I tried not to cum as I rubbed Bree's leg, and Marie rubbed her cunt. I wasn't even touching my dick, but I felt like I was on fire and about to explode. Bree's eyes were closed, and she was alternating between enjoying the calf rub and enjoying her sister masturbating her pussy for her. She could've been rubbing it herself really, but for some reason it had seemed logical that we should both be helping her, and this was how we could do it.

Marie knew what she was doing, too. More so than me, since she had a vagina herself. Marie gently ran her finger between Bree's pussy lips and even dipped it inside of her hole. Mostly though, she rubbed at Bree's clit and kept going in tight controlled circles. Finally, Bree's eyes shot open and she looked genuinely surprised.

"I'm going to cum!" she said excitedly, looking at both of us. "I'm so close..."

Marie eagerly kept it up, and even increased her pace a bit. I kept rubbing Bree's leg, but I had started to forget about it as I focused on her pussy. Bree started to grimace, and then she was thrusting her hips upward into her big sister's expert touch.

"Ugh!" she grunted. "Ugh, oh Marie...Oh..."

She came hard, and it looked heavenly. Marie's other hand was busy rubbing at her own pussy, and amazingly I watched as she climaxed right after Bree. It was so hot to see my sisters sharing an orgasm. I had to grit my teeth to keep my dick was spewing. After they both finished, they smiled at each other very lovingly, and then turned to me.

"Your turn," Marie said, and moved toward me.

I almost jumped back, because I didn't know what she was going to do. And thus far neither of them had touched me in a sexual way. Bree tried to sit up but now that I wasn't rubbing her leg, she winced and decided against it.

"Stroke him off onto my tits," she said. "I wanna be involved."

Marie reached for my throbbing erection and grasped it gently. Then she pulled at it to get me to move closer to Bree.

"Come here," Marie cooed, in a very soothing way.

I obeyed her, and without any further words from anyone she started to beat me off just above Bree. I had to stand and bend low, but I got my dick pointed right at my little sister. Her eyes were nearly glazed over with desire as she watched Marie jerk me off.

I had been so close, I knew this wouldn't last very long. I looked over at Marie and her slim naked body, and she smiled at me even though she was paying more attention to her technique. She must've given a handjob or two before, because she was really good at it. I tensed up, and she seemed to know what was about to happen.

"Ooh, come on," she encouraged me. "Right on her tits."

I squinted and thrust forward into Marie's tight grip, and felt my dick pulse and throb. A thick stream of cum shot out the tip and landed right on Bree's face, a little higher than we had planned. But the rest fell right onto her tits, splashing and pooling all over her. It felt so good to have my sister jerk me off, and it felt even better that I was cumming on my other sister's naked body.

Bree was on fire, I could tell. My cum on her skin had lit something in her. She licked her lips, and gently fingered the cum that had gotten on her face. Her eyes as she looked up at me said it all.

"That was awesome," she sighed.

Marie nodded, and squeezed the tip of my cock before letting go. "I can't wait till it's my turn."

I was in heaven, and I wasn't sure how this could get any better.

Chapter 7

For some reason, the three of us didn't get together for a couple of days after that "incident" in in the bathroom. It wasn't that we were avoiding each other, by any means. In fact, my relationship with my sisters seemed to be better than ever. Marie had usually ignored me mostly, and Bree and I weren't the type to be chatting with each other very much. But now, Bree was constantly around me, hanging out in my room or in the living room, and she seemed to want to talk endlessly with me about anything.

Marie seemed to perk up as well around me. We weren't just eyeing each others' bodies either, it was a warm and friendly type of demeanor. It was like the three of us were really good friends now. And we owed it all to something as silly as masturbating together.

Bree's leg healed up nicely, but she didn't go running with Marie for a few days. The day after she hurt herself, Marie didn't do her usual morning run because she had to do some errands with Mom. Bree had gone off to the lake with her friends, and of course Dad was at work, so I had the house to myself. I ended up sitting on my bed with my laptop, surfing porn and jerking off a nice big load into my stomach. I thought about Bree and Marie the entire time, though.

That night, no one came into my room and I didn't venture theirs either. It was kind of strange but it felt like there was this lull to our excitement of watching each other masturbate. I fell asleep before I could make sense of it. The next morning I slept in, and to my pleasant surprise I was awoken by Bree pouncing on top of me.

"Hey!" I said, pushing her off of me playfully.

"Wake up, lazy," Bree said, a very chipper tone to her voice this morning. "Everyone else is gone."

For some reason that clued me in to what she could possibly be wanting from me. Sure enough, when I finally rolled over and saw her, she was completely naked. That got my morning wood sprouting quite nicely. She just sat on the end of my bed, absolutely no shame or embarrassment at being naked with me.

"Where's Marie?" I asked, blatantly staring at her tits.

She shook them for my benefit and smiled. "She had to go do something for Mom cuz she was running late to work. She'll be back in a couple of hours."

I yawned and stretched, making my erection stand prominently underneath the covers. Bree pulled them aside, and when my penis came into view she licked her lips.

"You wanna go a round just the two of us?" I asked, knowing what the answer would be.

She nodded. "Yeah, I am really fucking horny."

This was old hat by now, so it was totally no big deal to be reaching for my cock to stroke it while Bree spread her legs and starting rubbing her pussy. Our legs were touching, which was even more exciting for me. I really liked this view because I could see everything about her. I could see that she was already very wet, and I could even see her cute little butthole every once in a while as she starting humping into her hand.

"What did you think about Marie touching her ass?" I asked, referring to our previous session in the basement.

Bree was huffing already, but spoke as if this was a casual thing to be talking and masturbating with her brother.

"It was pretty hot," she admitted, and then looked up at me instead of at my dick for a moment. "You want me to touch my ass for you?"

I could only nod, and my strokes got faster after hearing her say that. I watched as she opened her thighs even wider and gently separated her butt cheeks with each hand, first letting me see both her holes clearly. Then she licked her fingertip and touched it softly against her anal opening. She groaned quietly, and I wasn't sure if she was putting on a show for me or she was actually enjoying it.

"You like that?" she cooed, her voice raspy and sensual. "You want to cum on my little butthole?"

Oh my god, she was being so slutty I was going to lose it already. "Oh yeah!"

She scooted closer, raising her legs over mine and resting her calves on my hips. She positioned her cunt only inches from my cock, and if I really tried I could have probably touched the tip against her clit. But I wasn't sure she was ready for that. She was only trying to make it so I could aim and explode across her sexy body.

"Just keep stroking," she said, her eyes glued to my dick. "When you're ready, let it go all over me."

I stroked even faster, eager to watch my cum paint her cunt and her belly. But she had invited my to cum on her asshole, and in this position that seemed almost impossible.

"Can I...cum on your...I mean, your butthole...I can't..." I wasn't sure how to word it.

She nodded. "You're right, we want your cum on my ass, right? Ok, well see if you can get the tip right up against my hole when you cum."

That nearly sent me over the edge, but I held off by sheer desire to actually touch my cock against her sweet little asshole.

"So...I'm cumming...in your ass or on it?" I asked, genuinely confused in this state of arousal.

Bree's face lit up, and she got that devilish smile. "Ooh, you wanna cum in there? I'll let you. You can put the tip inside and let it squirt up in my ass. Oh god, that would be so hot!"

I spat on my fingers and rubbed it on the tip of my cock. I got it nice and wet, knowing I wouldn't need to stroke it very much longer before I blew. I leaned forward just a bit, and Bree lifted her ass off the bed just enough to get my pillow under her hips. She pulled her legs back and spread her ass for me nice and wide. It was obscene the way she was displaying herself for me, her own brother. And her tight little sphincter looked so delicious, I couldn't wait to do what she was asking of me.

"Do it, Kevin," she begged, looking up at me with pleading eyes.

"I don't even think I need to jerk off," I admitted. "I'll probably cum as soon as I get it in there."

She was excited by that thought, I could tell. She started playing with her clit again, and it only made the obscene display even more arousing. I aimed my cock down at her tight little hole, which would be stretching impossibly to fit my thick cock in mere seconds. I gently touched the tip against her hole, and she purred.

"This is so naughty," Bree said, raggedly. "Don't tell Marie we did this. It'll be our secret."

I smiled. That would actually be kind of fun. And maybe Marie and I would have our own secrets that Bree didn't know about.

I pushed softly, and her anus fought me for a moment. It didn't want to let my invading meat enter her tight passage. I was just going to put the tip in, it wasn't like I was going to actually fuck her ass or anything. I got more saliva on my dick, and my precum was also helping lube her up. This time when I pushed, her ass gave a little and I slipped in about an inch.

I just stared down at my cock head almost completely disappearing into my little sister's ass. Bree was going wild on her clit, making her ass clench. She pushed me right back out of her ass, but I was quick to get back inside. I slipped in about two inches this time. She groaned.

"Is that ok?" I asked, concerned that maybe I had hurt her.

She nodded. "Yeah, keep going. It feels really sexy. Oh god, Kevin, I think I like it in the butt..."

That did it, and I couldn't help but weakly thrust my hips forward as I came hard in Bree's butt. I slid in another inch and was not quite halfway inside of her when I exploded. I felt the sharp bursts of semen squirt into her butt, and I was lost in the pleasure of her tight ring clenching onto me as I came. I moaned as I emptied myself into Bree, and soon she joined me in climax. She cried out and her hand was a blur on her clit. We shared a wonderful orgasm together, for the first time actually joining our bodies. It felt so good, I wasn't sure I would be able to keep from repeating this in the near future.

I was still inside of her when it was over, and we were both panting. Bree was absently playing with herself still, and I really didn't want to leave her tight warm ass. We looked at each other finally, and I could tell Bree was still aroused.

"You want to...?" she asked.

I just nodded, knowing exactly what she was asking.

I pushed my cock further into her, and felt her ass split apart around me. Her hole was nice and slimy now, painted with my copious load of sperm. She gasped as I stretched her tiny little hole with my thick shaft. When I was all the way in finally, I just stayed there and tensed my dick as hard as I could. It felt really good to be inside of her, and it was the first ass I had ever fucked. Bree moaned and continued masturbating.

"It's really nice," she said with her eyes closed. "I think I can cum again."

"Do it," I said. "Want me to hold it here, or fuck you?"

She glanced at me only long enough to say, "Fuck me." Then she closed her eyes again and focused on her pussy.

I moved in and out of her slowly, gently even. Her ass was so tight I was afraid it might hurt her. I pulled my dick out of her ass just long enough to take in the sight of her abused little butthole leaking some of my cum, and then I pressed back into her. It felt so good, so right, to be fucking her, I almost forgot that this was my own sister and what we were doing was totally wrong.

She came, as promised, and a trickle of clear fluid seeped down from her cunt to my cock. She squirted! That really spurred me on, and I started fucking her harder. She looked up at me with a look of pure pleasure, a helpless and hungry look that told me she would take anything I could give her. I thrust into her ass like an animal whose only instinct was to fuck and claim what was mine.

I loved watching my dick disappear into her hole, and the way her pussy was clenching every time I slid back into her bowels. The forbidden nature of this act, aside from the incest, was really getting to me. I had cum only minutes earlier, but I was ready to go again.

"Inside?" I asked, barely able to get the words out through my pleasure.

She was huffing right along with me. "Yeah," she managed to say.

Finally, with an intense growl and a sharp thrust into her butt, I came hard again. My dick was so sensitive that it almost hurt when torrents of cum escaped my penis and filled her insides for the second time. I kept thrusting into her, pounding her ass and making it submit to me. Bree was whimpering now, maybe a bit from pain but ultimately she was simply submitting her body to me, letting me do whatever I wanted and getting off on the results.

When I finished firing off into her, I fell backward and slipped out of her ass. When I glanced down at her, still holding her legs spread apart in that position, her asshole was gaping wonderfully. My cum hadn't escaped her yet, she was holding it all inside of her like that.

"Oh, Kevin," she breathed. "I can't believe we did that."

Shit, was she regretting it?

"It was really nice," I said, and prepared to try to calm her and assure her everything would be ok between us.

"That was way better than masturbating," Bree said before I could. "Will you keep doing that to me?"

I could only smile and nod.

Chapter 8

That night, since I was very satisfied already from the anal extravaganza that Bree and I had enjoyed, I didn't bother to try to sneak into her room to play. I figured I would give her a break, and truthfully I wasn't sure I could perform.

But there was a soft tap on my door after everyone had gone to bed. The door opened and closed quickly, and I could only see the outline of a person approaching in the dark. When it got closer, I could barely make out Marie in her camisole and pajama pants.

"Marie?" I sat up in bed, squinting until my eyes adjusted.

"Hey," she said, and tiptoed right up to my bed. "Are you sleeping?"

"Obviously not," I answered. I was naked under the covers, but I wasn't exactly worried about her seeing me like this. "What's up?"

"Well..." She came and sat on the end of my bed, and I had a flashback of Bree sitting right there this morning. "It's just been a few days is all, and..."

I couldn't help but smile to myself, and to my surprise I started to get an erection.

"Yeah, I know," I replied. "You haven't gotten off by yourself?"

She shook her head. "I've been...saving it up, kinda."

"Why?"

She shrugged. "I dunno, I don't really enjoy it by myself as much as with you and Bree."

I didn't bother to ask why she didn't go to Bree first. I knew she liked cock better than pussy, after all. I pulled aside the covers to expose myself to her, and she smiled when my dick came into view.

"I already played with her earlier today," I said, holding back the details. "So I'm kinda spent, but I can try to keep up."

Marie pulled her shirt up over her head and tossed it aside. She stood up on my bed and pulled her pants down, and when they got past her knees she started to get wobbly on the mattress and fell forward. She landed right on me, her hands bracing her against my chest but her stomach landing right on my boner. It didn't hurt, but the sudden connection was a bit awkward.

"Sorry," she said, fumbling to get off of me so she could finish undressing.

"Admit it, you enjoyed that," I joked.

She seemed to wink at me, or at least that's what it looked like in the dark. "Maybe."

"Hey, remember how you said you liked it in the butt?" I asked boldly. I honestly wasn't sure where I was going with this, but it seemed logical to try to proceed that way with her like I had with Bree.

"Yeah, so?"

"Do you wanna do some butt stuff with me?"

There was a short silence as she considered what I might be asking of her. Maybe she wondered if I meant for her to touch herself, or rather for us to touch each other. By the slim chance that she would actually agree to the latter, I didn't say anything else.

"What did you have in mind?" she finally asked.

"I dunno. But if it's something you like, we should do it."

"Kevin..." She raised up onto her knees, and I could make out her small tits quite clearly. "You know we can't...have sex, right?"

I shrugged. "Hey, that wasn't what I was suggesting."

"I mean," she corrected herself, "we can't do anything that involves you cumming inside of me. Inside my pussy, that is."

I tried to hide my excitement as her words revealed to me that she may be up for something more than just touching ourselves. But I played it cool.

"I don't intend to do that," I assured her. "But...Bree and I...we've kinda taken it a bit farther already."

I hadn't meant to share that much with Marie, but it seemed like it would be in my favor to get a bit of a rivalry going between my two sisters. I knew Marie was competitive like that, always trying to best her little sister in anything they both tried.

Marie leaned forward a bit, and I felt her inner thighs on the top of my leg. She practically hovered over me, getting closer in some sort of sensual gesture like she was having a hard time keeping herself from pouncing on me. That had to be a good sign.

"What did you two do, exactly?" she asked, and her voice was already raspy.

I grabbed my dick and started stroking. "She let me put the tip in her ass and I came there. Twice, actually."

Suddenly I felt Marie's fingers on the hand that was stroking my cock. She moved them further down and pushed my own fingers out of the way so she could grab my erection and gently touch it. I groaned as I felt her feminine grasp on my penis.

"You two are fucking perverse," she said, in a sexual whisper that dripped with desire. "I can't let you two get away with that, without getting a piece myself."

My dick lurched in her hand. "You really want me to put it in your ass too?"

Her face was right in front of mine, and she was jerking my cock right up against her cunt. I could feel the tip brush against her slick bare vagina as she pulled on it.

She whispered in my ear, "I love getting fucked in the ass."

I could not have wanted her any more than I did at that moment. I thought she was going to kiss me, the way her cheek dragged along mine as she moved back to a sitting position. To my surprise, Marie crouched down and lowered her face to my crotch. I was in heaven as I felt the warmth of her breath and the lovely wetness of her mouth on my penis. Her tongue snaked out and licked at it first before she sucked the shaft down into her throat. In only a few movements, she had buried me in her face. Her nose touched my stomach just below my belly button.

I groaned heavily, and for the next few minutes I was amazed at how good a person could feel. It wasn't just the pleasure of her mouth and tongue working against my cock, licking and sucking at it and coating it with saliva. It was the reality that this was my older sister doing this to me, and wanting to do it more than any girl has ever wanted to before.

"Do you like that I'm sucking your cock," she said, "after it's been in Bree's ass?"

My god, I hadn't even thought of that! She was right, she was sucking the same penis that had invaded Bree's naughty little anus and filled it to the brim with hot cum. I grunted as she throated me again, and I felt her fingers graze under my balls to stroke me there in that wonderful place.

"Now you want my ass, right?" she asked, though she didn't need to.

She sat up and hovered herself over me, not letting me move even an inch. She positioned her hips over mine, and aimed my dick straight up. I watched, and felt, as Marie sank her ass onto my cock, letting it slide up into her tight butthole and go deep into her bowels. She moaned as she did this, rubbing her pussy as well but focusing on getting me inside of her ass.

"Oh, Marie..." I couldn't even say anything as she did this, it felt so good. I was now fucking the second ass I had ever fucked, and in the same day that I had my first.

After I was deep inside of her, and I could feel her body resting on mine, Marie started to masturbate. She rubbed her clit softly at first, gently grinding her hips on me and letting her ass undulate on my cock. She sped up her movements until she was panting and rubbing her cunt hard, pawing at it hungrily. This was the best sex I had ever had, and fortunately I wasn't about to cum too soon. I could thoroughly enjoy it for as long as I could endure.

She cried out as she climaxed on me, and her ass clenching on me as her pussy convulsed made me almost lose it. Just like Bree, to my delight, Marie squirted a small stream of clear liquid onto my stomach. God, that was so sexy, feeling the warmth of it spread across my belly. My bed would be a mess, but I couldn't care less right now.

"God, Kevin!" she exclaimed. "I can't stop cumming!"

I grabbed her hips and held her down onto me. She mashed her ass onto my cock, as if she was trying to stuff more and more of it inside herself. I felt like I was reaching up into her gut with my cock. The inside of her ass was rubbing me so wonderfully, just slightly different than a pussy would. It reminded me how naughty and forbidden this was, and how good it was going to feel to let my cum paint her insides. I remembered how Bree's ass had looked after I plowed it, all stretched out and gaping. Seeing my cum run out of her abused little hole was the hottest thing I had ever seen, and picturing Marie's ass doing the same finally sent me over the edge.

I threw my head back and let out a loud groan as I spewed up into Marie's butt. She smiled as she felt me tense up and lurch inside of her, and I came with enough force that she probably felt it squirting around in her bowels. She clenched her ass as hard as she could around my dick, and just held onto me as I enjoyed her body.

I collapsed back onto my bed, and Marie stayed on top of me. She wasn't going to let my dick escape her tight ass. She gently stroked my chest as I caught my breath. I pawed at her tits in return. It felt like we had crossed a barrier that even Bree and I hadn't crossed yet.

"How was it?" Marie asked finally.

"It was the best thing I've ever experienced," I answered truthfully.

She giggled. "Better than Bree's ass?"

"More intense," I said. "We didn't really get this much into it when we did it. It was more...innocent."

Marie slowly lifted off of me, looking down at where we were joined. We both watched as her asshole dragged up my shaft and finally my cock head popped out of her. Cum followed, trailing all over my dick in a filthy display of what we had just done.

"I guess I did suck your dick too," she said. "We really did have sex, pretty much. Anal sex, but still sex."

I nodded. "Then why doesn't it feel wrong? Why don't I feel guilty?"

She leaned back and rested on her elbows. "Because you're naughty."

I smiled. "Do you think we'll do this again?"

She rubbed her pussy thinking about the question. "Hell yes."

I sighed and stretched. This was the best day ever. And this whole sordid sexual adventure with my sisters wasn't over by a long shot.

Chapter 9

Despite the fact that I had fucked both my sisters in the ass, we didn't just skip out on the fun behind the shed. The next morning, Marie went out for a run and Bree and I were excited to be waiting for her in our usual spot. Bree's leg was still a bit sore from her injury, so she couldn't run with her sister. But she could walk just fine, and thus would be able to service herself this morning without needing Marie and I to do it for her.

"Did you really fuck Marie in the ass too?" Bree asked me as we both waited for Marie to get back.

I nodded. "You're not mad, are you?"

I honestly thought she might be, since she seemed to want to keep the anal sex a secret between just the two of us. Our relationship was different now, for sure. But it wasn't like we were dating or in love. We were just sex partners now, as were Marie and I.

"No, I'm not mad," Bree replied. "I thought it would just be more fun to keep it between us. But it's kind of hot to think that you've had your dick in both of us. And in our butts."

Bree giggled after hearing herself say that last part. I just smiled. Marie probably had another few minutes before she was finished with her run, and I was feeling especially bold now that I had been so intimate with both of them. I reached for Bree's breasts and grabbed one of her tits through her shirt. She looked flushed but didn't object.

"Oh I see," she smiled. "You think feels are free now?"

She responded by grabbing my dick through my shorts, which was starting to get very hard now. She squeezed it while I squeezed her full tit. I got ever braver and stuck my hand down her shorts where I felt her neatly trimmed pussy starting to get wet. Bree gasped this time, since I had never touched her down there before. But she wasn't stopping me, so I didn't withdraw my hand from her shorts.

"You're being bad," she whispered, as if anyone was around to hear us.

"I can't help it," I said, groaning as she reacted by reaching into my shorts and jerking on my cock. "I'm so fucking horny right now."

"I have an idea," Bree said, still jerking me off. "When you blow your load, try to squirt it on Marie. Try to hit her cunt."

I liked that mental image, and I'm sure Marie would find it sexy even though it might be shocking at first. Now that we had crossed so many barriers, I wasn't sure anything I tried to do with them would be met with rejection. I felt like I could just bend Bree over right now and plow her pussy. I couldn't cum in her though, that was definitely the one barrier that still existed. But as long as I pulled out...

My thought process was interrupted by the rustling of Marie running through the backyard and over to where we were waiting for her. She was panting and sweating, looking especially drained from her run.

"Sorry," she said, seeing our hands all over each other but not batting an eye. "I really pushed myself today, just wanted to get my adrenalin going."

"Ready?" I asked, pulled my shorts down.

My two sisters did the same, and we were once again facing each other in a circle behind the shed. My dried cum stain was still visible on the face of the wood, which was sexy in my mind. It was evidence of what we were doing, and if anyone saw it they wouldn't think twice that it wasn't just a typical weather stain.

The three of us started to masturbate. Bree was being careful with her pussy, apparently so aroused that she was ready to burst at any moment. She was purposely going slow to avoid climaxing too soon. Marie was harder on her cunt, rubbing it fiercely and trying to force the pleasure out of it. She must be trying to get there while her heart was still pumping to take advantage of the adrenalin that made her orgasms so nice. I stroked rather absently, at a nice medium pace so I could enjoy watching both of them.

Marie was suddenly climaxing, after only a few minutes. Bree shot a look at me, at the same time speeding up her own pace to match her sister's. I stroked faster as well, remembering that Bree wanted me to shoot off onto Marie's bare cunt. It would be tough to get it on her pussy and not her hand that was in the way busily rubbing at her mound. Marie closed her eyes and savored the feeling of her orgasm, while Bree started whimpering as her own started.

I watched my two sisters in various stages of climax, and felt the stirrings in my balls as my own orgasm was now available whenever I needed it to happen. I nodded to Bree, and she peaked as she realized I was about to cum. Marie was distracted by her sister's noises, and I could have sworn she looked turned on by them, so it was the perfect opportunity to step even closer to her and aim my cock at her stomach. I grunted and fired off a nice thick shot that sailed through the air and splashed right at her belly button.

It was a bit too high, and Marie's shocked look was a bit distracting, but I managed to get the rest of my load to land right on her mound. The first shot in her belly button oozed down and joined with the rest of it at her pussy lips. Bree lost it again and came a second time when she saw the mess I had made of Marie. Marie seemed truly surprised, but she thrust her hips forward a bit to allow me better access once she realized what I was trying to accomplish. She let me finish cumming on her, and when I was finished squeezing the last drops out she held herself like that for everyone to see.

"You pervert," she smiled at me. "You were both planning that, weren't you?"

I nodded, still holding my dick. Bree was panting now after two quick orgasms.

"I thought it would be sexy," I replied. "Thanks for letting me do it."

Marie gently touched my semen painting her skin, and rubbed it around a bit. "I suppose you told Bree about us?"

I glanced to Bree, who only smiled. "Yeah, I did."

Marie scooped some of my cum into her hand and playfully rubbed it on Bree's cheek, making her squeal. WIth their shorts still down around their knees, they chased each other in the small space behind the shed, trying to smear my cum on each other.

"I think we should just forget any pretense of privacy," Marie said when they were finished, "and start fucking together."

We were all pulling our shorts up, and I froze in place. "What?"

Bree clapped her hands together excitedly. "Oh, Marie, that sounds wonderful. I would even try eating your pussy if you wanted me to."

"Well, I didn't mean that exactly," Marie said, taken aback by her sister's lesbianistic offer. "But we'll just have to see how it goes. I think it would be more exciting to do it together, just like when we masturbate together."

I couldn't believe my luck, and my dick was still rock hard. It tented obscenely through my shorts. Marie and Bree both laughed at it.

"Didn't you get enough?" Bree asked, playfully swatting at it.

"Sorry, thinking of having a threesome is kind of hot," I replied.

Marie winked at me. "I guess I had a good idea, then?"

"How are we going to pull that off?" Bree asked. "After everyone goes to bed? In the basement?"

Marie straightened her running shorts, and wiped at the semen on her stomach like it was no big deal. "Yeah, we'll have to do it down there just in case they hear something in our bedrooms. It would be really hard to explain why all three of us are naked together."

"I can't wait!" Bree said excitedly.

We all went back into the house to clean up.

Chapter 10

So there we sat, in the basement after Mom and Dad had gone to bed. We told them we were going to play a game and then go to bed, which wasn't completely uncommon. And not completely a lie, either...

We were all in our pajamas, both Marie and Bree in their camisoles and me in a pair of sweatpants and an old t-shirt. We absently talked and joked for a little while, listening to the sounds of our parents walking around upstairs. Once it was silent and we were sure they were in bed, the tension in the air rose to an almost uncomfortable level.

We kept talking, maybe all a little nervous about what was about to happen. We shouldn't have been, because it was going to feel great and wasn't exactly foreign to us. I hadn't been in either of their pussies yet, but I had cum in their butts already. We had seen each other naked and at our most vulnerable many times already. I was rock hard the whole time, and Bree was fidgeting anxiously. Marie was on the couch, just like that first time she had confronted us about watching her behind the shed. Bree and I each took one of the bean bag cushions just like before too.

Finally, when there was a break in the conversation, we just kinda glanced at each other, waiting for someone to take the lead. Marie was usually the one to do it, but even she was reticent it seemed. Bree couldn't take the silence for very long though.

"So," she blurted, "what should we do first? Blowjob?"

Marie looked at me and blushed, probably imaging how she had already sucked my dick once. I just smiled at her, hoping she would agree to that.

"Ok, but we should try doing everything together," Marie replied. "That includes giving Kevin a blowjob."

Bree was beaming wide, eager to suck my dick it seemed. I was glad, but getting a double blowjob from my hot sisters was a little too surreal. I almost felt dizzy at the prospect.

"Come on," Marie said, getting off the couch and crawling toward me. "It ain't gonna suck itself."

Bree laughed and also crawled over to me. Without saying a word, I watched my sisters peel my sweatpants off and toss them aside, then situate themselves comfortably so they could both reach my sprouting cock. I groaned as I felt one of them start licking the underside of my shaft while the other one grazed my balls with her tongue. My head fell back and my eyes closed, even though I really wanted to watch this happen. But as long as no one freaked out, this would be happening many, many times more in the future. I would get my chance. Right now, I just had to fight back my orgasm and try to enjoy it at the same time.

"We're not stupid," Marie said, taking her mouth off my cock to speak. "We can tell you're close. You're pulsing, for god's sake."

"We'll keep sucking you even if you cum, ok?" Bree said, her mouth muffled a bit by my balls.

Fuck, that was almost too much to hear! I gritted my teeth and finally looked down at my beautiful sisters sucking on me. Marie and Bree alternated between stuffing my cock as far into their throat as it would go while the other one sucked on my nuts and licked my taint. This was going to be over embarrassingly soon, but at least it would feel awesome. When they happened to touch their lips together while trying to alternate their oral skills, I finally lost it.

I groaned and my eyes squinted as the semen rushed forth from deep inside of me. In a powerful explosion of released tension, my cum erupted from the tip of my cock and spewed all over. All over me, Marie and Bree. Marie was licking my taint hungrily when it happened, so she mostly avoided the mess. But Bree was rubbing her lips and tongue up and down my shaft, she her mouth and cheeks and forehead took a lot of the load. She was positively a mess when it was all over.

To my surprise, they were true to their word. They kept sucking and licking all over my groin, ignoring the cum that soiled me and them. They were like starving animals, and I was enjoying the results of their hunger immensely. I finally came down from the pleasure of my orgasm and just enjoyed the relaxing feel of them blowing me. It was the nicest thing I had ever felt thus far, even better than fucking their assholes and cumming deep inside of them.

"Ok," Marie said, withdrawing her face while Bree kept sucking on me. "Enough for him now. We need to get some."

Bree nodded, giving my balls a last kiss. Her face was a mess but no one cared. She didn't try to wipe a single drop away. We were all in a haze of sexual lust right now.

"Can we 69?" Bree said to her big sister. "I've always wanted to try that."

Marie raised an eyebrow. "Are you..."

Bree wasn't shy about admitting anything right now. "I like girls too, ok? At least, I wanna try eating a pussy. I might not get a chance unless you let me eat yours."

"You're assuming I want to eat your pussy," Marie countered.

Bree's pleading eyes were begging Marie to try it out. "Please? Please, Marie?"

"Come on," I said, trying to encourage Marie to do it. Of course, it was for my own selfish and voyeuristic desires. "I need to get hard again to fuck you both, and watching will get me there for sure."

She looked down at my dick, which was still completely hard, but didn't object. She finally gave in and nodded.

"Ok, I'll do it." She sighed. "I've never done anything with a girl before, but it doesn't seem the same if it's with my own sister."

"Exactly!" Bree said, stripping naked and sprawling back with her legs spread. "You can be on top if you want."

Marie got naked too, and carefully got on top of Bree. It was comical to watch them negotiate the positioning of their bodies, but once they were in place, it was the sexiest thing I had ever seen. Bree was ready to dive into Marie's smooth pussy, but Marie seemed hesitant to make physical contact with the neatly trimmed cunt only inches from her mouth. They both stared at the other's pussy for a moment.

"Come on, Marie," I said. "You said you would."

"I will," she said. "I'm just admiring how pretty your pussy is, Bree."

Bree took that as the sign, and immediately she latched her tongue onto Marie's clit.

For the next few minutes, I was in absolute heaven. It was like every teenager's masturbatory fantasy, watching two girls, much less my own sisters, lezzing out on each other in horny abandon. Bree was especially wild, slurping on Marie's perfect cunt and wrenching the orgasm from it. She barely made a sound, but Marie was whimpering and moaning the entire time. The first time Bree made her cum, her energy seemed to spike and suddenly she was trying to be just as eager on Bree's pussy. Bree finally thrashed a bit and came quite intensely as well.

They kept going on each other, licking and sucking and slurping and tasting. I just watched and jerked my cock. I could have cum to this, but I held off because I knew something better was only moments away. Still, it was majestic to watch two sexy girls who knew how to please their own bodies use those same techniques and skills on each other.

Each girl came twice, and then they were finally ready to fuck. I approached with my rock hard erection in hand, and waited for them to decide who went first.

"Can you last for a little while?" Marie asked me.

I nodded. "Yeah, at least for a few minutes each."

"You should fuck Bree first," she said.

Bree was excited, but also curious. "Why?"

Marie smiled at her. "You're not on the pill yet, are you? I am."

I realized that she was saying I was going to get to cum in her pussy. My dick lurched in my fist, and my balls rose up into me a bit. Shit, maybe I wouldn't last...

"That's not fair," Bree said with a frown, even though she was spreading her pussy lips erotically for me. "I want his cum in my pussy too."

"Tell Mom," Marie said. "Well, not that. Just that you want to get on the pill."

Bree sighed. "I guess my ass will have to do if I want it inside me."

"I'll cum wherever you want me to," I told Bree as I knelt over her. I aimed my cock right at her cunt. "Right now, just let me fuck that sweet little hole."

Bree cooed as I touched the tip at her entrance, and slowly invaded her wet pussy. I stretched her a lot, almost as much as I had stretched her asshole, as I worked my way up into her. She groaned as I bottomed out and held me tight against her. Marie was right beside us, encouraging us and gently touching both of us.

It was strangely erotic to have someone else present during sex. I had always thought it might be embarrassing, or even boring for the person who wasn't getting dicked. The hardest part was keeping my orgasm at bay, especially as Marie gently stroked my balls from behind when I was deep inside of Bree, or when I watched them kiss passionately. If Marie hadn't been into girls before, she was definitely open to it now. When she was kissing Bree and her hand snaked down to touch her sister's pussy as it was getting fucked, I felt the impending explosion.

"Shit!" I exclaimed, and pulled out of Bree.

"All over her," Marie said without hesitation, as if she was waiting for me to burst.

I grunted and came hard. I fired thick bursts of semen across Bree's naked body, splashing it onto her stomach, chest, neck, face, everywhere. I couldn't believe how much I was producing, considering how soon it had been since my last orgasm. But it was all there, waiting to be released onto my sexy little sister. After I finished, Marie was licking at Bree's tits where I had painted them.

"I'm sorry, Marie," I apologized. "I tried to hold out, I really did."

She broke her kiss with Bree and leaned forward to kiss me instead. Her tongue snaked into my mouth and intertwined with mine, to my surprise. I hadn't expected to be kissing either one of them during this sexual adventure, but it felt good to be doing it.

"It's ok," she reassured me. "We're not going anywhere. As long as it takes, you're going to keep fucking both of us until you're ready to cum. And it's going to be inside my pussy."

I pawed at Marie's cute little tits while Bree masturbated below us. She was rubbing my cum into her skin with her other hand. Marie reached for my dick and started to jerk it, oblivious to the slimy mess of combined fluids that was soiling it. It felt good when she did that, even though I was a bit sensitive right now. She kissed me again, and kept jerking me off like that just above our sister.

"How about if he fucks our asses?" Bree offered, watching us kiss and touch each other. "That should get him ready."

Marie smiled, and winked at me. "Sounds like a plan."

I nearly fainted from the mental image of what we were about to do. I couldn't believe my own sisters wanted me to fuck the life out of them like this. But here we were, doing just that, with no end in sight.

Marie bent over and spread her ass for me, exposing her tight little sphincter. She turned her head to looked back at me while she did that.

"Do you think you can manage that?" she asked.

I looked down at my cock, still hard for some strange reason, and nodded.

"I can certainly try."

Not really. That's all they wrote. The End.

I enjoyed this, but I don't like how it escalated so quickly. I would have liked a bit more build up personally

The plot does a Herculean polevault in chapter 7 but I guess that's a compromise with quick fap material. I liked the rest of it.
