"You know, if anyone finds us in here..." Simon was cut off by Kaylee's lips pressing against his.

"Depends who it is." She said breathlessly as they broke apart. "If it's the captain, sure, we'll be in trouble. If it's Jayne...we could make a lot of money."

"Kaylee!" Simon groaned, shuddering at the mere idea. But at the same time, he tried and failed to keep from laughing. "That is depraved."

"And you love it." Kaylee giggled. She gave herself a mental pat on the back for this idea. Lately they'd been 'surprising' each other during the day, meeting up and sneaking off to some private spot somewhere on the ship. Minutes earlier, she had found Simon walking through the cargo bay and pulled him into a far, dark corner behind a stack of crates.

He'd protested at first, pointed out how likely they were to get caught. But Kaylee had convinced him quickly enough. Somehow he found it difficult to say 'no' when she was kissing the breath out of him and slipping her hand down his pants.

Not to mention that lately all it took for him to get hard was the sound of her voice. It was like Pavlov's gorram bell. He might have been embarassed by his reaction if it hadn't been obvious that he had a similar effect on Kaylee.

"God, Kaylee, what you do to me." He groaned against her neck, fumbling with the zipper on her jumpsuit. She let it slide down to pool at her feet, kicking one leg out of it so she could wrap herself around him.

"Nothin' more than you do to me." Kaylee replied. She knew exactly what she did to him. She kissed, stroked, and sexed the Core right out of him, and it made her insanely proud. Her smirk faded and her mouth dropped open when he slipped his hand between her thighs. He gave her a wicked grin when felt her wetness on his skin, with no cloth barrier seperating them. "Laundry day." She panted.

"Right." Simon chuckled. He slid a finger into her, then used his free hand to push her shirt up, just far enough to expose her breasts. He was so focused on her, on the taste of her skin and the way she gasped when he added a second and third finger inside her, that he didn't really register that her hands were busy until she had his pants unzipped and was pulling his cock free of his shorts, stroking insistently.

Kaylee felt another rush of pride when she felt him swell harder under her touch. She felt herself getting closer with every thrust of his hand. Then it was gone as he slid his fingers out of her and set her on her feet. Before she could protest, however, she felt his hands on her shoulders, turning her around to face the wall. "Simon?" She said softly, instinctively reaching out to brace herself against the cold metal.

"Trust me." He whispered, kissing the back of her neck. He wrapped one arm around her waist and moved his hand between her legs, rubbing her clit. "Okay?"

"Uh-huh" Kaylee sighed, leaning back against him. "Simon..." Her voice trailed off as he moved his hand from her hip up to her breasts, teasing her harded nipples. Shivering with pleasure, she blindly reached back to wrap her hand around him. Her body was literally aching for him.

Simon must have sensed how desperate she was becoming, because just as she opened her mouth to beg him again, he pushed himself into her, nearly shouting at the feel of her body drawing him in deeper. She was slippery-wet perfection, hot and tight around him, arching back to meet his thrusts.

Kaylee pressed her hands hard against the wall, trying to hold herself up as her legs started to tremble. She moaned continuously at the exquisite stretching and pressure and the feel of his hands sliding over the front of her body, pinching her nipples before sliding down to tease her clit. He felt so hard and hot, and the angle of penetration made him feel even fuller inside her, to the point that she could already feel her orgasm starting to build low in her belly.

He lightly scraped his teeth against the back of her neck, making her cry out. The sound echoed and he quickly moved one hand to cover her mouth. The sounds she made when he was inside her were amazing, but that didn't mean he wanted the rest of the crew hearing them.

Her climax came on faster than she expected and lingered, a full-body shiver that left her slumped against the wall, gasping for air as Simon moaned and thrust deep into her before he came. He fell against her, resting his forehead on her shoulder.

"Simon?" Kaylee whispered hoarsely after a moment.

"Hmm?" He murmured, kissing down her neck.

"Your turn." She giggled. "Gonna be tough to top this one."

Simon laughed and turned her around, holding her up against the wall. She looked like a goddess to him, with her skin flushed and damp and her eyes shining. "I'll think of something. Maybe we can set a new record today."

Kaylee gasped at the thought. "Five times in one day?" She grinned at him as she straightened her shirt and pulled her jumpsuit back up. "You just name the time and place." She leaned up and kissed him. "I gotta get back to work, and I'm sure someone on this ship needs some kind of medical attention."

"Yeah, usually a safe bet." Simon agreed. He kissed her once more before they seperated, then checked himself over to be sure his clothing was in place. When he looked back at Kaylee, she was headed up the stairs. She looked over her shoulder and smiled at him, just a simple, quick smile.

Simon groaned softly and headed to the infirmary. He had some serious planning to do.
