Simon bent Kaylee over the engine, keeping a firm hand on her hip as she wiggled away from him, stretching her arms out in an effort to reach the offending part. He had told her this wasn't a good idea, but with a bat of her eyelashes and a heart-stopping kiss, she'd managed to get him up here. And now, as Simon did his best to ignore the feeling of her butt wriggling against his groin, he had to wonder at his own stupidity. "Ai ya!" Wincing, Simon heard the sound of Kaylee's wrench banging against metal and another string of obscenities that honestly made his ears blush. "Are you okay?" he asked concernedly, trying to adjust his grip on her and see past her shoulders at the same time. "Stupid gorram coil," she muttered back, her voice hard to make out as she tried to talk through the machinery and piping between them. "Simon, you gotta move me closer." Glancing down to her hips, which were now firmly planted against his abdomen, Simon asked, "Um, how exactly?" With a sigh, Kaylee dropped her head for a moment, steadying her balance against the nearest, non-heated engine part. Wishing she had someone to help her who actually knew something about machines, she told him, "You know, jus-" Squirming against him again, Simon hurried to balance her, a strong arm wrapping all the way around her slim waist. Edging closer to the engine, he moved slowly, worried her head might come into contact with a wayward part. "How's that?" "Better!" He sighed softly and then did his best to hold her still, trying to ignore the burning sensation in his arm as he held her there for a prolonged period. There was more clanging and banging and Simon found himself smiling softly as Kaylee continued to curse. In truth, the sight of her perfect backside resting against him and the slightly forceful words that were coming out of her mouth were causing him to think something far removed from engine repair. Was it always this hot in here? "Gotcha, you lil' bugger!" Her triumphant cry was punctuated with a small squeal and Simon could only smile. "Can I pull you out now?" Barely able to hear him, Kaylee continued fiddling, trying to get the useless coil out of the way. Shaking the old part in Simon's general direction, she told him, "Here. Take this." Grunting with the effort of balancing her and reaching for the piece of machinery, Simon felt a small bit of sweat bead along his forehead. Grasping for Kaylee's hand, Simon told her through clenched teeth, "I can't get it." "Just grab it." "Kaylee, it's not that easy." Zoe paused outside the door to the engine room, her hand against the jamb and listened, the scowl on her features dissipating into a smirk as she eavesdropped. "Ya ain't gonna hurt it," Kaylee was ordering, her voice edged with forcefulness. "Just yank it out." "I don't want to break it."

"It's already broke." "Problem?" Zoe cleared her throat as she stepped into the engine room, doing her best to hide her smile as Simon craned his neck to look at her, his features flushed with exertion and his brow furrowed into a look of frustration.

"Just a bit," Simon muttered, again shifting Kaylee against him and releasing the smallest hiss as she continued to rub him in all the right ways. Turning pleading eyes to Zoe, Simon nodded in the direction of Kaylee's flailing hand and asked, "Would you mind?" Without a word, the first mate moved to the engine and took the part from Kaylee, chucking it easily across the room and onto the work bench. Looking back to Simon, they shared a smile as Kaylee again began to work, the sound of her humming to herself causing Simon to hiss through his teeth. He couldn't resist her when she hummed, she had to know that. Noting the younger man's distress, Zoe leaned towards him and confided, "I helped Wash out once. Fixin' one o' the consoles on the bridge." As Simon regarded her with a puzzled expression, she added with a small smile, "Longest three hours o' my life, watchin' him get all sweaty an' layin' next to him in those tight quarters." His mouth gaping like a fish, Simon found all coherent thought left him as Zoe's words sunk in. Without another word, the Amazon woman headed out of the room, the small smile still on her lips as she more fully relived the good memory. Simon watched her go, wondering when exactly his entire life had turned into one giant sexual joke. First it had revolved around his inability to act on his desires and now it seemed to focus on his inability to do anything but. "I'm almost done, sweetie." Kaylee's voice brought his eyes back to her and he smirked at the sight before him. It wasn't much more than her rump, but it wasn't a bad view and he was enjoying it. What is wrong with me? Simon shook his head, trying to dislodge the dirty thoughts that were floating through it. I am not a sexual animal, he kept repeating, shutting his eyes and trying to focus on something completely inane. I am not Jayne, there is more to life than sex. However, whatever image he conjured - the engine, the ship, the cargo bay, the infirmary - somehow wound its way back to Kaylee and her exquisite form ... and all the things they had been doing in the privacy of their bunks - or the cargo bay, the infirmary, the engine room ... "Sweetie, can you pull me back now?" Scrambling, Simon tightened his arm around Kaylee's waist and carefully extricated her from the engine. Setting her gently on her feet, she turned to him, grinning madly and Simon found himself leaning in to kiss her. She was surprised at first, barely having caught her breath before his lips had covered hers with a passion that he normally reserved for when they were alone. But quickly, she responded, molding her body to his and smiling wide against his mouth as she felt his excitement. Pulling back, she cupped his backside and pressed them together firmly, murmuring, "Did I do that?" Simon growled softly at the movement and then smiled to her, one of his famous swai grins that always left her breathless. "What do you think?" he asked her huskily, again leaning in to kiss her. Kaylee giggled and returned the kiss, delighting in how turned on he was. Maybe having Simon help in the engine room wasn't such a terrible idea after all.
