"Which movie are we watching tonight?" Sidney asked, setting a bowl of popcorn onto the coffee table before making her way over to Billy, planting a kiss on her boyfriend's lips while she settled into his lap. Billy wrapped an arm around her waist to keep her steady and kissed her back with just as much passion and affection as she had.

"Prom Night," Randy suggested, landing on the couch beside Tatum, who scoffed and leaned closer to Stu.

"Let's watch Halloween!" Casey piped up from the other recliner, coming up for air in her makeout session with Steve Orth, her boyfriend of six months. Like Sidney with Billy, she was also sitting on his lap.

"Nightmare on Elm Street," was Stu's addition while tugging Tatum closer to his side so she was half in his own lap.

"Why does it always have to be a horror movie?" Tatum asked.

"Because horror movies are the best, babe!" Stu exclaimed.

Eventually, they settled on the first Friday the 13th. It was a classic.

As the lights went down and the opening credits began to play, Sidney adjusted herself so she could still somewhat see the television but have the opportunity to hide her face in Billy's neck. She didn't like horror movies, but she had to admit that Friday the 13th wasn't the worst one out there.

As her hips moved into place, she heard Billy give a low grunt.

"Are you okay?" She whispered.

"Yeah," he said tightly.

Sidney's brows furrowed in confusion. He didn't sound okay. He sounded as if he were in pain.

"Are you sure?" She asked, concerned as she moved again to get a better look at him.

Billy gripped her hips. "I will be when you stop moving," he hissed through clenched teeth.

For a moment Sidney was puzzled by his response, but then her eyes widened when she realized why he wanted her to stop moving. She gave an experimental swivel of her hips and she felt it. He was erect against her pussy, the head poking against the crotch of her jeans. She shivered a bit while Billy let out a quiet groan.

"Fuck," Billy cursed. "Are you trying to kill me?"

"You're hard," Sid murmured. The realization that she was turning him on just by sitting in his lap made her feel warm, butterflies fluttering in her stomach.

"I'll get harder if you don't stay still."

She giggled softly and moved her hips again, pressing her crotch firmly against his.

The scream of a camper in the movie behind her covered the sound of Billy's growl.

"If you keep doing that, I won't be able to control myself," he warned her, his hands tightening around her hips.

"Then don't," she said slyly, beginning to rock her hips back and forth. It wasn't long before she found a rhythm.

"Fucking vixen," Billy snarled, his own hips thrusting up against hers.

Sidney buried her head into his neck, muffling a moan into his skin. In her peripheral vision, she saw Tatum sneak a peek at them and give her a smirk. Other than her best friend, though, no one seemed to notice what she and her boyfriend were doing.

"You feel so good. I wish our clothes weren't in the way," Sidney whispered into Billy's ear, grinding harder against him.

Billy growled at her and dug his fingers into her hips, so hard that she knew she was going to have bruises by morning. "If we were alone right now, I'd tear your clothes to shreds and fuck you until you passed out from exhaustion," he replied, returning every one of her grinds against his erection with a thrust against her covered pussy.

Sidney whimpered at that and moved more desperately now. The faster their pace, the louder their noises. Luckily, the movie was picking up in its soundtrack as more campers were being picked off by Mrs. Voorhees, so their sounds were still covered. Still…the thrill of one of them being too loud and their friends catching on was intoxicating and it made them want to toe the line even further…

Sidney bounced on his lap, whines escaping her mouth as she ground her clit against him through her jeans. She was getting so close, it wouldn't take much longer…

Billy was in a similar position. Feeling his girlfriend's curves through her clothes, her heat…it made his jeans tighten further against his cock. He was going to end up cumming in his pants like some pre-pubescent boy who'd discovered masturbating for the first time, but he didn't care. All he cared about was reaching a release against his girlfriend, the woman he loved most.

"Oh, God…Billy…" she panted, her hands resting on his chest, her hips bouncing on top of him as if her life depended on it.

"Fuck, Sid," he groaned.

Only seconds later, just as the climax of the movie hit, so did theirs.

Sidney buried her head into Billy's neck, biting him softly as she came, her pussy tingling and clenching around nothing as she rode out the waves of her orgasm.

Billy growled from the back of his throat, the sound muted but absolutely primal, his boxers flooding with cum. Thrusting harder against her to wring himself dry, his hips finally coming to a stop with a grunt of her name.

They stayed like that for a while, bodies trembling and breathing ragged. Part of them missed the skin-to-skin contact, but neither could deny that losing themselves to a sexual frenzy and bringing themselves to the peaks of their intensity in such a public place like the living room in their friend's house felt just as satisfying as real, penetrative sex did.

The room flooded with light again as they came down from their highs, Friday the 13th's end credits rolling down the screen, the white text a stark contrast against the black background.

"I love that movie," Stu announced, grinning widely as he moved to retrieve the tape.

"It was okay," Casey shrugged.

"What do you two love birds think? Or were you so scared to watch it that you hid in Billy's neck the entire time, Sid?" Tatum asked, smirking knowingly at her best friend.

Sidney raised her head, grinning back at the blonde still reclining on the couch. "It was good. I got scared, but Billy helped me out," she praised, kissing her boyfriend's cheek before returning her head to its spot against Billy's neck.

A slow, content smirk stretched Billy's lips. "Yeah," he agreed. "I took care of Sid when it got to be too much for her."
