Kelly Sienna was the perfect student: she had excellent grades, a friendly demeanor and not a single vice that may impede her bright future. The only complaint anyone had about the quiet young girl was that she came off as a bit too shy or boring. That hadn't stopped Chris from falling in love with her from afar; he'd been drawn to her the moment he saw that cute look of embarrassment that spread across her mousy features whenever a teacher called on her. He'd spent hours just staring at the way she nervously played with her curly black hair, or admiring the way the slightly-too-large dresses she wore hung from her slender frame. When he'd finally worked up the nerve to ask her out on a chilly autumn morning two years ago, she'd turned beet red. The whole time, she was stammering and looking around wildly like something would come and save her. Chris was sure he'd be rejected at any moment when she finally blurted out.

"S-sure!"

In the time since, Kelly had made it very clear that study and school came first, which was great for Chris' grades but felt stifling at times. The teen had even agreed to wait until graduation to have sex, something his friends gave him no small amount of grief over. Still, Chris had convinced himself that a kiss at the end of their study dates was enough.
It was on one such study date that Chris found himself yet again regretting his promise as he watched the mid-afternoon sun illuminate his girlfriend's pale skin. She was explaining something about quadratic equations but all he could focus on was the way her dainty hands gestured as she spoke. Finally, he'd had enough. He took one of her hands in his own and wrapped his other arm around her, before thrusting his tongue into her mouth. She had to want it just as badly as he did right?
They stayed like that for a moment; a soft moan escaped her lips before his hand started to wander. This snapped Kelly out of her haze, pushing her off of him.

With a hasty, "I think I should go!" she ran from the house, leaving Chris alone, aroused, and licking his lips.

Panic began to set in as Chris paced around his living room, one thought echoing repeatedly in the emptiness around him. "I screwed up. I screwed up. I screw-"

"knock-KNOCK-KNOCK" Kelly's signature knock beat out from his from door, causing Chris' heart to sink even lower. It definitely wasn't like her to come back to a problem immediately. She must be furious. Steeling himself, he opened the door, prepared to beg and grovel. Sure enough, Kelly was standing there, but she was wearing a look he'd never seen before. Her usually demure features were replaced by a coquettish grin. Stunned, Chris tried to work up an apology only to be silenced by Kelly placing one pale finger against his lips. "It's okay, tiger." She cooed, her tone radically different from before. "I was beginning to think you didn't have it in you."

Pushing him back onto the couch, Kelly knelt before him, her small hands reaching for his belt. "Now, stud, I think you deserve a reward." With deft movements she pulled down the stunned teen's jeans, revealing a tent that grew tighter by the second. She giggled tauntingly as she noted his apparent nervousness.
"What's wrong stud? You're shaking." Chris swallowed, closing his eyes slowly as if Kelly would snap back to her usual shy self. When he opened them again, she was still there, the lust apparent on her face as her perfect fingers began to run lightly across the outline of his cock. She giggled again. "C'mon, where's that bravado from before? Show me what I've been waiting for."
"Y-yeah." Before had just been a fluke, he told himself. She's obviously even more turned on than he is. Hesitantly, Chris freed his now erect member, and watched it bob powerfully just inches from his girlfriend's face.

She looked at it the same way one would look at a well prepared meal; a massive grin spread across her uncharacteristically confident features.

"Now that's what I'm talking about, tiger; one bold move deserves another." Her tongue darted out, playing along the throbbing head, Chris reacted immediately to the alien warmth, his hands digging into the couch cushions as he locked eyes with her. Kelly stopped with a pout. "You want more, you'll have to show me. Stop being such a wimp!"

Chris, still shaking and nervous, whimpered at her teasing. "How?"

Kelly just rolled her eyes, grabbing one of his hands by the wrist and placing it on the back of her head. "You're lucky you're so cute."

Chris finally started to think with the right head. Twining his fingers through her hair, he pressed her head toward his cock. Kelly opened her mouth invitingly before taking the head into her mouth entirely. A look of pure bliss fell on her face as she snaked a hand between her own legs.
Hesistantly he began to pick up the pace, still not quite believing what was happening, he pushed and pulled, slowly, her fingers playing in and out of herself in pace with his motions, pulling herself off Kelly purred contentedly, rubbing his cock against her cheek absentmindedly as she spoke. "From here on, I want this morning day and night. I want you hard and ready 24/7." Punctuating her words with quick strokes from her free hand and wiggling her hips she added "And if you really impress me, I'll let you take charge down here, too."
This was enough to break Chris' last barrier. As his hand pressed her head back onto his length, he was rewarded with a throaty moan as the arm between Kelly's legs began to stir. Grabbing her hair more tightly he began to pull her back and forth, reveling in the soft slick feeling of her mouth. The more he pushed and pulled, the more her tongue danced around him, lavishing the underside of his cock. Meanwhile, the model student jilled herself more and more furiously, her mischievous eyes locking onto his and drinking in his hazy features. Chris had given himself over entirely as he began to thrust into her mouth. The low vibrations of her now constant moaning pushed him to the edge. Just as he could feel his balls begin to tighten, his cell phone rang. Kelly pulled off of his cock with a delighted pop, saliva still connecting her lips to him. Her free hand wrapped around his slickened rod, pumping furiously.

"Go on, answer it."

Chris flicked open the phone without looking at the caller ID, and listened to the silence on the other end while Kelly moaned loudly. Her fingers finally pushed both of them to the edge of orgasm.

Chris was just about to hang up when Kelly pumped his cock one last time, placing just the tip into her mouth. Chris lost control of himself and launched strand after strand of seed onto Kelly's lapping tongue. He'd forgotten about the phone in his hand when the caller finally spoke, the shy voice chilling him to the bone.

"I-I'm sorry about today... I hope you can forgive me."

Kelly's quiet apology came from the receiver as Chris stared in horror at 'Kelly' kneeling before him, her hand pumping absentmindedly at his cum slick member.

"Chris? Are you there?"
