I thought I’d not only blew my load that night, but my chances of getting anything more. Luckily I was wrong, or we wouldn’t have gotten Powered. “I went to bed right after but I couldn’t sleep,” I explained to my sister at the breakfast table. “I just lay there for like, hours, trying.” And trying to think of ways to repeat our encounter. If that first encountered wasn’t so mind-blowing, I might not have been so eager to try again. “I think I got Powered up then, I just didn’t realize it.”
“Well, I didn’t feel anything.”
“No, but we didn’t teleport until after you came, and I got my powers after I did.” It was also the only time I could remember deliberately cumming on her... after that, she always resisted anything that would lead to that... she'd even jerk her hand away and make me finish myself if I told her I was about to cum and we weren't using a condom. I put together what we knew, a tentative hypothesis. “So maybe I get powers if you make me cum, and you get powers if I make you. Directly, I mean, not with condoms. If you’d let me return the favor that night, we could have known about our powers months ago.”
“If you weren’t so selfish about giving head we could have known about them a couple weeks back.”
“Me, selfish? You wouldn’t even blow me without a condom most of the time. And you never actually asked me for head, or to keep going when I started on my own. If you want, I’ll do it right now.” A flushing sound from upstairs reminded us we weren’t exactly alone in the house. “Well, not right now.”
She sat for a moment, thinking, then asked, “Do you think it’s just us? Or do we just get Powered by sex with anyone?”
“I don’t know.” I’d always held off asking the question. Tabby had never had a boyfriend that I knew about, and yet I knew she wasn’t a virgin, either. “I mean, you’ve, uhm, had sex before me, right?”
“Just one guy,” she said. “And we always used protection, and I never came anyway, so… no evidence either way.” She shrugged. “What about you?”
“Same,” I said. “I mean, we always used protection.” The truth was, my sexual history was far less than I’d let on. Some making out, a bit of dry-humping, I might have got something going with one of the girls at my old school, but then we had to move in a hurry, and so the first time I’d sealed the deal was with my sister. “I guess we really don’t know.”
“That’s if your theory is true,” she said. “Right now it’s just a hypothesis. We’re going to have to test it… are you okay with that?” I smiled in response. She smirked. “Yeah, somehow I thought you’d be. So… today after school?”
“What’s after school?” said my youngest sister Sally, walking into the room with a yawn. She’d probably just woken up a few minutes ago, and looked it. Her dark brown hair was a tangled mess, much of it overhanging only one side of her face, but she would probably go that way to school. When my sister didn’t answer, she repeated “Tabby? What’s after school?”
“Nothing,” Tabby snapped. “And don’t call me Tabby. You’re supposed to call me Kathryn, even at home.” She wasn’t really mad about that, I knew, it was just an effort to change the subject. My little sister often slipped up and called my sister by her old name. We all did.
It worked. “But Alex calls you Tabby all the time!”
“Yeah, well, I’ve given up all hope for him. I don’t want you imitating his habits.” I grinned sheepishly. I was worst of all. So far, Sally was the only name change I’d adjusted to, mostly because she always hated her birth name and was overjoyed at the chance to change it, and so bitched at me whenever I slipped up. At least no thought was required for our parents… Mom and Dad were still Mom and Dad.
“I don’t see what the big deal is. We just say it’s a family nickname.”
“Forget it, unless you want me to start calling you Lucy again.” Apparently looking for another subject-change, she added, “Put some clothes on, the Boyds will be here in ten minutes to take us to school.” I looked over instinctively at the suggestion… my little sister wore only a t-shirt and panties which peeked through the bottom, clinging tightly to her ass. She didn’t even have socks on. I forced my gaze quickly back to my breakfast for fear of Tabby thinking I was attracted to Sally, too. I was, a little; Sally was still mostly flat-chested but was already developing a bit of a figure… but I didn’t want either of them knowing it. Maybe I was a horndog... guys aren't supposed to be look at either of their sisters that way.
Tabby seemed oblivious to my look, and Sally didn't even see it happen. “I will in a second, I just wanted to ask, will you make me French Toast for breakfast?”
Tabby gave an exasperated sigh. “No, I’m not going to make you French Toast. It’s a weekday, and there’s no time. If you wanted French Toast you’d have to be up like half an hour ago.”
Sally pouted, and then brightened immediately. “Cinnamon toast, then?”
With a roll of her eyes, Tabby waved her away. “Fine. Go get dressed. I’ll put in the toast.”
My little sister went of running, yelling over her shoulder, “Not too dark, remember. And we’re out of cinnamon sugar, so you’ll have to mix some!”
Tabby got up from her breakfast and unscrewed the cap of the little container we used to hold a mix of cinnamon and sugar, then fetched the bottle of cinnamon from the pantry. She looked over at me as she poured out a little into a measuring cup, and caught my grin. “What?”
“You are so easy.”
She frowned. “You know, that’s very hurtful. And such a double-standard, too… if I'm easy, what are you?”
I put my hands up defensively. “I just mean…” I pointed to the cinnamon sugar. “You know she didn’t really want French toast, right?” Cinnamon toast was one of my little sister’s favorite foods, and I liked it now and then myself. The problem was, Sally was very lazy. She's the type of person where, if there were no clean plates, she’d rather eat over the sink than wash one, and if a meal required any preparation at all more complicated than putting cereal and milk in a bowl or butter on bread… “She just wanted you to do the work.” Although come to think of it, I’d used similar techniques early on when I wanted to do something sexual with her… I’d propose far more than I thought possible and then bargain her down.
“Oh, whatever,” she said, no longer seeming bothered. “I don’t mind. I like taking care of people.”
For the next couple minutes we had the kitchen to ourselves, but then all of a sudden it was as full as it ever got. Dad came in first, dressed in his work clothes, a blue dress shirt, dorky tie with cartoon characters on it, and dark slacks. He’s thin like all our family, but in his case comes off a little scrawny, in fact, he all-over kind of embodied a geek look, with a nose too big for his face and a $5 haircut. I guess he’s okay-looking in an insurance salesman kind of way. Actually, my dad usually looks more like a high school science teacher trying too hard to convince his students science can be fun. All he was missing was the white lab coat, and he puts that on in the lab, at least I’d assume. He worked for the government on top secret projects, which is why certain criminal forces wanted him and why we had to change states and go into witness protection. “Good morning,” he said cheerily.
“Morning, Dad,” Tabby said. I grunted a hello through a drink.
Sally came back in next, dressed in her school clothes, jeans and a t-shirt, hair still a mess. “Is my toast ready?” Tabby passed it over, and Sally bit into it without so much as a thank you.
My mom finally emerged, wearing a bathrobe. Her raven hair was wet, and she must have just emerged from a shower and had a relaxed glow. She had the luxury of a little more time, she didn’t usually leave for work until about a half hour until we were all gone. Luckily us kids inherited most of our looks from my mom, not Dad, because she was practically the definition of MILF. Plump tits and ass, but a skinny waist. I’m not saying I’d like to fuck her, but it wouldn’t take a whole lot of convincing. Okay, I guess I really am some kind of horndog.
My dad’s cell phone rang, and he answered it, with a simple, “Okay, come on up.” After closing it, he explained, “That’s Jim, he’s on his way up the steps. Alex, can you let him in?”
I was finished breakfast, so I did, went into the living room and opened the door to see my Dad’s driver/bodyguard/co-worker/friend Jim. He didn’t look like a scientist, he looked like a businessman. He was well-built but balding and even a little ugly, but was a pleasant enough guy. He even had a couple coffees in one of those cardboard trays. “Hey, George. Here to get your Dad. Your own ride will be here in,” he checked his watch. “Two minutes.”
“You know, you can call me Alex.”
“No, I can’t, and you shouldn’t either. You were supposed to abandon your old identities, names included. Even at home.”
“Come on, George Grant? No, I just told everybody I go by my middle name. Sure, on all the official forms, I’ll be George Grant, but I don't care, I’m still getting everybody to call me Alex. You might as well, too.”
He shook his head with a distracted grunt. He knew it was a losing battle with me. “You might disregard the rules, but I won’t. It’s protocol. If someone ever notices nobody ever calls you by your name, they might get suspicious.”
“Isn’t it more suspicious for us to have to get a ride to and from school every day instead of just taking the bus?” I asked, for probably the twentieth time. It was a sore point, though… it felt like we were the prisoners, instead of the people who threatened Dad and attacked us, who really should be.
“It’s just a precaution.”
“But we’re supposed to be dead,” I said. “I mean is anybody even looking for us?”
“As far as we know, you’re safe, but your parents want to be extra careful. I’m sure next year we can go down to agents following you from a discreet distance.”
I rolled my eyes. “Lovely.”
Dad came out, briefcase in hand, and reached for the extra coffee. Mom followed close behind. “Thank you, Jim,” Dad said, raising the coffee to his lips and taking a sip.
“No problem. Good morning, Mrs. Grant.” Grant wasn’t even our real last name, either, and though it was easier to pretend, it still felt weird to be called it.
“Morning, Jim. You keep him out of trouble.”
“I’ll do my best ma’am,” he said with a good-natured grin. He nodded at Tabitha when she entered the living room and sat on the couch beside me.
Mom closed the distance between her and Dad and they both leaned in for one last kiss. When they broke away, Mom said, “Have fun at the lab.”
“Not as much fun as I have here,” Dad said, and swatted Mom’s ass playfully, causing me to look to Tabby and both of us rolled our eyes. “Bye kids, love you,” he said, and then, when he realized his youngest was still in the kitchen, yelled out, “Bye Sally!” With that, he was gone. Mom watched from the door until they got in and drove away, like she always did. I guess she was worried the car would explode if she didn’t.
“Looks like the Boyds are here,” Mom said. “You guys had better get your things.”
The Boyds' arrival was scheduled, but even a family under government protection can’t run on a clock. Between Sally misplacing one of the books she needed for school and Tabby and I fighting a bit over the downstairs bathroom, and then Tabitha wanting to change her top because she realized she spilled some milk on it, by the time Mom gave us a goodbye kiss at the door, we were five minutes behind the plan and Roger Boyd was tapping his feet impatiently.
Roger Boyd was a tall guy just verging on overweight, with light ginger hair. Mark Boyd was shorter, older, with dark hair. Their cover was that they were our uncles, or that Mark was, anyway, which was why they drove us to school. We never were entirely sure if they really were a gay married couple or if it was just cover for them too, but they certainly weren’t really related to us. Like all the people assigned to watch us, they were pretty nice, but Roger was a little high-strung and was easy to get a rise out of. I always got the feeling he would snap one day and kill someone, and it would be because we wouldn’t follow the schedule.
My sister Sally seemed to take great pleasure in trying to provoke that meltdown herself. “So, I was thinking, if we’re late anyway, how about we just blow off school today and go to Cedar Point instead?”
“We’re not late, we’re just not on schedule… and no matter what, you need to go to school.”
“Oh, come on, one day! We’re not going to learn anything important. It’s a half-day anyway.”
“Don’t try to lie to me, your next half-day’s the last day of school.”
I couldn’t resist joining in. I didn’t want a homicide, but maybe we could provoke them into abandoning the chauffer ride and let us make our own way to school. I pointed at a busy donut place up the street. “Hey, can we stop off for a coffee before school? I didn’t get much sleep last night.”
“No.” Roger said through gritted teeth. “We’re not stopping for a coffee. We’re behind enough as it is.”
“Please? I could also use a coffee,” Sally said. “The drive-thru’s right there, there’s only like six cars.”
“You’re twelve, you don’t even drink coffee!” Roger snapped. Mark just smirked.
“I could drink coffee,” Sally said seriously.
“No!” Roger said. “No coffee, no amusement parks, we’re taking you to school and that’s it.”
We were silent for the rest of the drive, then just before we got to school, Sally got a sly grin and asked, “Hey, Roger, I forgot, what’s our witness-protection last name supposed to be again? Green?”
He smacked the steering wheel in frustration. “GRANT! You’ve been the Grants for months! Do we have to go through another round of drills?”
Mark finally took pity on his partner. “Guys, you know Roger isn’t a morning person, take it easy on him. Here’s your stop.” That was directed at me and Tabby, the high school was looming ahead. “Have a good day at school.”
***
About seven hours later, we were back in that car, on the way home. Normally the ride home is more somber than the ride there. In fact, although I don’t think any of us would admit it, I think we all looked forward to school, as boring as it was, because it was easy to interact with others. At home, we never really have complete freedom, if we want to go somewhere we can’t just up and go, we have to get permission, and often a ride or an escort. We’re not actually prisoners, even though it feels like it sometimes, Sally has a lot of extra-curricular activities, and we’ve all been out with new friends in our new city, who have no idea about our situation, but compared to people who weren’t hiding from organized crime, it felt like our social life was seriously compromised. So, unlike back in Crash City, there wasn’t usually that excitement, that visceral sense of freedom, and all that’s left is the aftershocks of a day of boring classes that beat you down.
Today was different though, at least for me. It had already been a great day, and knowing about our upcoming experiment, it was due to become even better. Even if it turned out that our powers were a one-time fluke, I’d still be doing more with my sister than I’d thought possible a few months ago, and that alone was exciting. When you added in the possibility of becoming super-heroes, I was practically grinning the whole ride home. Tabby was similarly excited, even though we didn’t say much, we kept meeting each other’s eyes and she had a half-smile.
My little sister Sally, she had no idea of the byplay between us, but she was usually pretty cheerful after school anyway. Of all of us, she’d adapted to the situation the best and had already made tons of friends. The first order of business, though, would be to get her out of the way.
“Either of you want to play Rock Band with me on the Hypercube?” Sally asked when we got inside.
“Maybe a little later,” Tabby promised. “Right now I need Alex's help for an assignment.”
She looked dubious. “You need HIS help? Shouldn’t it be the other way around?”
“Hey!” Sure, my sister got way better grades than me, but experience counts for a lot too. “I’ve got two extra years of stuff she’s never learned.” And there were a few things I was naturally better at... history, for example, especially of the Superhero age. One of the few times Tabby's gotten in trouble academically was for falling asleep in history.
Sally dismissed the thought that I might have something to offer. “Pfft. Can you make me a sandwich, first?”
That request wasn't to me, but I answered anyway. “Make yourself one,” I suggested.
“Tabby makes it better.”
My sister rolled her eyes. “Fine.” She looked at me. “I’ll meet you downstairs.”
I went down into the basement to wait. I complain a lot about being forced to move out here, away from our old lives, but one of the few things I love is my room. The basement is just three rooms. There’s a laundry room, a small utility room that contains a fusebox and some storage space, and then the rest of the basement is just my room. It’s more than twice the size of my room in our old apartment building, and it might even be a little bigger than the master bedroom. I have a computer, TV, my own Hypercube gaming system, a nice stereo and, most importantly, privacy. The windows were all covered and I could hear anybody coming down the stairs with plenty of time to stop if I was going to be doing something like surfing porn or masturbating. It would also be a good room to smoke weed with friends in if I still did that or had friends I wanted to bring over, an even better room to have a girlfriend over for sex if that were ever an option, but since it wasn’t, I had let it turn into something of a pigsty.
I realized that I was bringing a girl here, sort of, so I did some quick straightening up, turned on a fan (it got a little stuffy down there sometimes) and sprayed some ‘Hurrah!’ deodorizing spray around just in time to hear Tabitha coming down the stairs. She knocked lightly on my door. “It’s unlocked.” She slipped inside, and locked the door behind her. “So, you ready to try this?”
“Yeah,” she said, walking further into the room. “I mean, I guess so. We have to know, right?” I nodded. “Should we have sex, or…”
“Maybe later. I thought we’d test to see if it works on oral first.”
She bit her lip adorably. “That would mean I’d have to let you shoot in my mouth.” Under the current theory, anyway. “You know I’ve never done that before, right?”
“It’s no big deal,” I said. “You’ve sucked me before, you just have to follow through to the end. And this is in the name of science.”
“Okay,” she said. “Whip it out.” I sat down on my bed and undid my pants, and let my cock out. It was up and ready to roll. If it had a mind of its own, it wouldn’t be able to believe its luck.
Tabitha sat down beside me, then bent over towards me, her lips just inches from my dick, so close I could hear her breath on it. “Here goes nothing,” she said, and her mouth closed over the head of my dick.
I fell back on my elbows and enjoyed the slippery, silky warmth as she went down on me, not all the way, but about halfway down. “God that feels good,” I said. She'd gotten better from the first awkward tries, with the condom, and her tongue slid excitingly on the underside of my shaft.
Her head bobbed up and down twice more, and then she pulled off and took a deep breath, as though she’d been holding it instead of breathing through her nose. “Warn me when you go off, kay?”
“Remember, to test the theory, I have to cum in your mouth.”
“I know,” she said a little peeved. “Still warn me. I don’t want to, like, be surprised and choke or something.”
“Okay, okay,” I said, putting my hand on her head. “Just get back to work.” She continued to suck me for a minute, and then pulled off again. “Don’t keep pulling off,” I advised her. “I might accidentally shoot when you’re taking a breather, the experiment would be wasted.”
She rolled her eyes. “Yeah, I’m sure you’ll be heartbroken that I sucked your cock for nothing.“ She shook her head. “How long is this going to take, anyway?” How long I lasted depended on how horny I was. Sometimes, I'm not proud to admit, I would have gone off by now, but not today.
“Longer than this,” I said. I held my dick in one hand with a few fingers, to keep it steady and the stimulation up. She wouldn’t go all the way down anyway. “If you want it to go faster, give me something to look at.”
She only thought about it for a moment, and then pulled her top off. Her bra this time was one of those ones with a little center clasp, and she undid it, letting those beautiful tits fall free. She let me look at them… actually it was more like a stare, before grinning and going back down.
Her breasts were right there, so while she was going down on me I extended one hand and cupped it, squeezing gently, feeling the nipple. She let me do it, of course, and that still astounded me. More, if this theory was true and we did get super powers, then it was possible we’d have an excuse to fuck all the time. Usually we did what we did and then felt a little weird about it for a while, a couple days would pass before we got over it, but I thought about us fucking every day as a matter of course, just to charge up our powers, getting over all shyness because this was something we needed, instead of just something I needed that she helped me with. That’s how I thought of it, anyway… although I knew she liked the compliments, and I knew she enjoyed herself during the act, I always expected she’d one day tell me that I should find a girlfriend and to stop coming to her. But I didn’t want to stop coming to her, and if this became permanent…
That thought tipped the scales, changing the game from stimulation to an oncoming ejaculation. I could feel the pressure beginning in my balls. “Okay, Tabby, here it comes. Don’t pull off.” My hand moved from her breast to the top of her head, to make sure she wouldn’t. I mean, if she really tried to get away I would have let her, but I didn’t want a moment of panic spoiling this.
I exploded, both into her mouth, and into pleasure. I knew, right in the moment, that our little experiment worked. The climax filled me and penetrated every part of my body and as I continued to shoot off into her mouth, I realized it wasn’t fading the way normal ones did. Once again, I was Powered.
I felt her trying to pull away, and this time I let her. As soon as her mouth left my cock, she turned to the side and coughed. “God,” she said. “I almost did choke.”
I realized nothing was left in her mouth. “You swallowed?”
“I didn’t really have much choice, it felt like I was drinking from a hose.” She made a face, coughed again, then seemed to compose herself and looked at me. “So?”
I grinned. “It worked.”
She grinned back, her eyes dancing. “Really?”
I nodded, stood up, and did that same type of concentration, almost like flexing a muscle, that I’d done the previous day to fly. Except this time, I didn’t rise in the air, there were no waves of force coming off my legs. I looked to my sister, puzzled, and she just stared at me. Stared while staying unnaturally still. No, I realized after a second, she was moving, just very, very slowly. Too slow. I turned to the fan, and the blades were whirring so slowly I could see them. There was only one explanation. I let go of the muscle-flex and said. “I have super speed.”
She stood up and said. “Super-speed, huh, so, let’s see what you can do.” She casually walked to my desk, quickly picked up a Hypercube game box off a desk, and threw it at me. “Think fast.”
It was halfway to my head before I sped things up again, and picked it up in the air. I put it back on the desk and was going to leave it at that, and then had a better idea. What could I do, and how fast could I do it? With a grin, I dropped to my knees in front of my sister, still crouched in mid throw. I undid the button and then pulled down the zipper. A bit of an odd thing happened. Normally when the button is undone and you pull down the zipper, the front flaps of the jeans spread open. This time they didn’t… it took a second before I realized, that that was happening in slow motion too. It was falling open, but at this rate, it would take several seconds. I helped it along, and not only pulled it apart, but pulled the pants down to her knees. Her panties were there, matching the bra, white in color, and I slipped my fingers under the waistband and dropped them too. There was her pussy, unsuspecting. I felt a little like a voyeur, and then looked up and saw the look of shock spreading on her face. She’d felt something already. I was fast, but couldn’t get away with my first thought… taking her pants and panties off and putting it back on before she even realized they were gone.
What I’d done was good enough, so I let my perceptions return to normal and watched as her mouth, already half-dropped open, completed its movement, and her hands went down belatedly to try and stop her pantsing. “You jerk,” she cried.
“Hey, you wanted a demonstration.”
She looked down at herself, and shrugged. “Well, it’s your turn to give me powers anyway.” She pulled her feet out of her pants, and bent down over the bed, sticking her ass up in the air. I could see her pussy poking up from behind.
“Let’s give it a try.” I knelt down on the floor, sticking my tongue in her pussy, nose pointed up towards her ass, which I grabbed, a cheek in each hand. I’d never licked her at all it in quite that way, the few times I'd done it, my nose was usually close to her clit, but surprisingly, it didn’t smell… or rather, it did, but not like anything bad, it like really concentrated sweat, but my sister, even her sweat didn’t smell bad, and with getting the taste of her wetness on my tongue made the sensation downright pleasant. And I enjoyed the feel of her trembling ass under my fingers while I licked.
My tongue ran up and down her slit, and then pushed the folds of her pussy apart and I licked from side to side. “Oh, fuck,” she said softly after I’d been doing it for a while. “You’re using super-speed, aren’t you?”
I hadn’t realized until she said it, but I was. My tongue was moving faster than usual, especially from side to side, with no muscle strain, and when I realized it, I moved it even faster, provoking a squeal from her. Yet, this time, I wasn’t experiencing a perceptual slowdown. Maybe that kicked in only when I was going too fast to control myself, or maybe that part was just voluntary. My tongue roamed all over her, cunt, provoking panting, grunts, and most encouraging of all, she was pushing back into me, like she wanted more.
The thought of that made me hard, or rather, made my penis jerk and I realized that I’d never completely gone down after I came last. That had happened last time, too. Could I fuck her again? What if I came again, would I get even more powers? I couldn’t seem to fly this time, maybe the powers were different each time.
More importantly, staring into my sister’s quivering pussy as I made her gasp and grind into my face made me aroused. I’d said I’d eat her out, but I wanted to fuck, and it sure looked like she did too. I let go of her ass cheeks and stood up. “What’s going on, why did you stop?”
“I’m not stopping,” I said. “But this is more fun.” More fun for me, anyway. I rubbed my dick briefly on her slick hole, and then pushed in.
“Are you ever going to finish what you start?” she asked, I guess referring to that I’d still never licked her to orgasm like I often said I would. “It was going so good.” I guess a superfast tongue had its advantages. It was then I had my idea, the penis might not really be a love muscle, but muscles are involved. I wondered if I could twitch them at super speed, and then gave it a try. The response was pretty well immediate. “Oh god,” she cried, far too loud for two people who weren’t alone in the house. “It’s like you’re a living vibrator!”
“Shh,” I said softly, worried my little sister might hear us from upstairs, even while the sound of an early-90s Zeppelin track audible down where we were proved Sally was playing her game with the volume way up. We were probably safe, and so I pumped my hips, driving myself into her, trying not to do THAT at super-speed, but I think I was going faster than normal, and harder, too. Tabby’s hands steadied herself on the bed, but it felt like I was gaining ground, pushing her more and more forward and down into the bed.
The further I got into it, the harder it was to keep track of my speed. The instinct is always to go fast, and although I knew I was holding myself back, because the thought of giving her friction burns was always in the back of my mind, pretty soon I was thrusting as fast as humanly possible. My sister’s ass was still up and proud, but now her face was buried in my bed, as she tried to muffle her own cries of “Oh god, oh god….”
Finally she closed her eyes tightly and squealed. I continued to pound into her, slowing to just about normal sex speed so I could enjoy the feeling of her pussy squeezing on me during her climax. When that stopped, I upped the pace again, and although there was a space of about a minute where she was pretty much just a passive hole, soon she was grunting and pushing back into me again.
She had her powers again, I could tell that when she turned her head to the side, spotted my pillow, and soon, it was surrounded with those little purple flames. A moment later, it was in front of my sister, and she used it to rest her head.
Good thing she did, too, because a few minutes later, she was burying her face in it to smother another scream as she climaxed again. At that moment, I felt my own orgasm approaching… I had the oddest certainty that I didn’t have to cum, I could have stopped it and continued fucking her, but, who the fuck would do that? I let it happen, let the feeling overwhelm me, and squirted into her while she was still screaming into my pillow. I just groaned softly, feeling great, but also different. One difference was pretty evident… I’d slowed down, a lot. It wasn’t tiredness, I just couldn’t seem to push myself in and out with such repetitive speed any more. I tried to slow down time again, and instead found myself taking to the air. My dick slipped out of my sister, leaving a little trail of cum, and I toppled over her head, barely recovered and landed beside her, both of us breathing heavily.
“Wow,” she said after a minute. “Okay, so, I’d call that a successful experiment.” Another deep breath. “Was it just me, or was that way better? I mean, not just because you were doing that vibrator thing.”
“It was pretty good, yeah.” I have a slight talent for understatement. “And now we know how our powers work...”
“Yeah,” my sister said, turning on her side and pulling her legs up on the bed while she looked at me. “Unprotected sex definitely charges us up.”
“Not just that,” I said. “I think we get different powers based on how we cum. You gave me a blowjob, and I got super-speed. When I came the second time, my speed was gone, and I could fly again.”
Her eyes widened. “You didn’t have super-speed the first time?” I shook my head. “Damn. I just got teleportation again.” She grinned evilly. “You know what this means, don’t you? You’re going to have to eat me out, all the way, just to find out what we can do.”
I smiled. “I think I can live with that. Not right now though, I don’t exactly want to taste my own sperm.”
“Oh, but it’s okay for me to taste it…” she teased, then grew thoughtful. “I wonder if it’s just us doing it together that does it, or if it’s sex with anybody.”
“It’s definitely us,” I said.
