Summary: Casey SHOULD HAVE been in the gymnasium, dancing the night away with Truman. Instead, she found herself in an empty classroom, making out with none other than Derek Venturi.

Casey McDonald giggled delightedly as her step-brother of nearly three years backed her into the chalkboard, all the while suckling at the base of her neck and marking her as his own.

It was Prom 2009.

The theme?

Not important.

At least in Casey's mind.

However, since it was her senior year, she should have been in the gymnasium, dancing the night away with Truman. Instead, she found herself in an empty classroom, making out with none other than Derek Venturi while their respective dates probably stood around wondering where the two had gone.

Casey smirked.

If only they knew, she mused, just as Derek pulled away and took a step back.

"I can't believe you actually agreed to go to prom with that creep." He remarked disdainfully, brows furrowing.

Casey made a face.

"It was your idea." She reminded him.

Derek merely rolled his eyes. "Yeah, but I thought you'd have more sense than to say 'yes'. I thought you were going to reject him… publicly humiliate him… something! I was planning on basking in his misfortune!"

"Aww… poor you." Casey said, feigning sympathy. "But don't worry… I'll always be yours and yours alone. Besides, just think of it as payback for kissing Emily." She wrapped her arms around his neck. "Now… where were we?"

All of his inner troubles immediately vanished at her words, and Derek crushed his lips to hers with bruising force. Casey moaned, tangling her fingers in his messy hair, and the infamous slacker quickly used it to his advantage by allowing his tongue to invade her mouth and intertwine with her own. It was during this time that Derek's greedy hands roamed everywhere: over her chest, down her toned stomach, under her dress and finally settling between her thighs.

"Mmm… no panties, Case? You naughty girl." He murmured, breaking the kiss as his fingers grazed her opening, causing the McDonald girl to gasp loudly.

"What can I say?" She breathed. "You bring out the rebel in me."

Derek's lips curled, his eyes flashing wickedly. Then, without warning, he picked her up and spun her around, only to set her down on top of their Math teacher's desk. Casey parted her legs in anticipation as she watched him unzip his pants and pull out the hardened length that she loved so much.

"Like what you see?" Derek taunted, stepping between her open thighs and pressing the tip of his member against her already wet entrance.

"I'm sure you already know the answer to that." She replied, hooking her legs around his hips. "Now… fuck me."

"With pleasure." Came the self-assured response, before he buried himself deep inside of her.

Fifteen minutes later, Derek and Casey cleaned up after themselves and exited the classroom. Although still slightly flushed, most of the evidence from their previous activity no longer remained -- they'd fixed their hair and adjusted their clothes so that no one would be able to detect a thing, and sure enough, as the two strolled into the gymnasium and reunited with their dates, no one noticed anything out of the ordinary.

No one noticed the overly-satisfied smirk on Derek's face, and no one noticed the hobble in Casey's walk.

No one even noticed the giant hickey on the side of her neck -- not even her date.

And that was exactly how they liked it.

I wish I knew what to say about this… but I don't.

I just hope you enjoyed it, Ash.

Happy Valentine's Day!
