"Have you seen Kaylee?" Simon had so far asked Zoe and Inara, and neither of them knew where the young mechanic was. He was making his way through the ship and had reached the cargo bay, where Jayne was lifting.

"Nope." Jayne replied, breathing heavily as he set down the weight. He saw the bowls in Simon's hands. "Hey, food!"

"For Kaylee." River cut in, leaning down from her hiding place on the catwalk above the two men.

"Ah!" Jayne yelped, sitting up so fast he hit his head on the bar above him. "How long you been there?"

River ignored him and looked at her brother. "Kaylee's in the empty shuttle."

"Thanks, mei-mei." Simon called up to her.

"Hey, where you goin'?" Jayne asked, rubbing his forehead. "I'm injured!"

"Not anywhere that you'd notice." River giggled, making Simon grin as he climbed the stairs.

In the empty shuttle, he found Kaylee sitting in the middle of the floor, tools around her and a frown on her lovely face. "Hungry?" He asked.

"Oh, hi, sweetie!" Kaylee looked up, her face changing instantly. "Aw, you brought me lunch?"

"Thought we could have a picnic, of sorts." Simon replied, handing her a bowl of noodles and a pair of chopsticks. He saw hesitation on her face. "Don't worry, Inara made lunch today."

"I wasn't worried." Kaylee told him. She held the chopsticks awkwardly, dropped them a few times. Then finally, as her frustration increased, the thin wooden sticks snapped in half between her fingers. Letting loose a string of Chinese curses, she pushed her bowl away and buried her face in her hands.

"Baobei, what's wrong?" Simon asked, immediately moving to her side and putting one arm around her shoulders.

"I don't know." Kaylee moaned. "I think I'm goin' crazy or something. I can't do anything right today and I don't know why. I keep droppin' stuff, I can't figure out what's wrong with those stupid controls. It's like overnight I've turned into the biggest klutz in the 'verse and I got no idea why."

Her bottom lip was starting to tremble and her eyes were welling up. Unable to bear the look of sadness on her beautiful face, Simon pulled her close. "No, that's not it at all. You're probably just having an 'off' day. Everyone has those. I had a few of them at the hospital, even after I'd been there for more than a year. I'd break I.Vs, spill things, forget my charts. It drove me crazy, but it always passed, and so will this."

"You really think it's just a bad day?" Kaylee sniffed.

"Absolutely." Simon reassured her, kissing a tear off her cheek. "Kaylee, with the possible exception of my government-trained assassin sister, you are the least clumsy person I know."

"Really?" Kaylee asked. River was so graceful. That was one of the last words she would ever apply to herself.

Simon closed his eyes for a moment, thinking of the graceful, fluid ways Kaylee moved when they made love. His body responded, and he knew there was no way she wouldn't notice that. "Really." He replied shakily.

Kaylee's face brightened when she felt him stir against her hip. "Well, maybe I'm bein' too hard on myself. I mean, just because I'm having a hard time with the fixin' stuff today don't mean I'm turnin' totally useless." She turned in his arms and shifted her backside against him, emphasizing the word 'hard' as she did so.

"Right." Simon gulped, barely hearing her over his pulse pounding in his ears. He glanced towards the open door, knowing exactly where Kaylee was planning on taking this encounter.

As if reading his mind, she jumped up and shut the door and locked it. Then she turned and leaned against the door, smiling at him. It was a predatory smile, and he found himself enjoying the thought of being her prey.

Kaylee was back in his arms instantly, running her hands over his back as he pulled her in for a sweet, soft kiss that she quickly made more intense, pushing her tongue against his lips, which he parted quickly for her.

He flinched a little as her hands moved down to his zipper and fumbled with it, something she'd never done before, and he briefly remembered the way the chopsticks had snapped in her hand. Reaching down, he guided her hand as she freed his already straining erection and wrapped her fingers around it.

With her free hand, Kaylee pushed Simon so he was lying flat on his back. He kept guiding her hand up and down on his cock, squeezing to increase the pressure of her fingers. He didn't notice her using her other hand to pull down her jumpsuit, which was already unzipped to her waist, until she shifted on top of him to pull one leg out of the canvas and her panties at the same time.

He sat up then, catching her off-guard. Taking his hand off of hers, he used both his hands to push up her t-shirt and her bra, freeing her full, firm breasts and instantly cupping them. She moaned and arched forward, which pressed her slick folds against his length. He sucked in a breath when he felt how incredibly wet he had made her with just a few kisses and light touches.

"God, yes." Kaylee whimpered, starting to rub herself against him. "That's good, Simon. That's so good." She trailed off as his mouth latched onto one sensitive nipple, pulling it in deep and suckling firmly.

Simon groaned, amazed at her response. Every time he tugged or laved the hard little bud in his mouth, more of her juices slicked his cock, dripping down the hard length of him. He was surprised at how responsive she was to having her breasts touched and stroked, even more than she usually was.

He didn't have time to ponder her reactions, though, because when he switched his attention to her other nipple, suckling it in the same fashion as the other, she let out a choked cry and slammed herself down onto him, taking him into her body so fast and hard that it knocked the breath out of him for a moment.

"Fuck!" Kaylee cried out, squeezing her eyes shut and taking in a sharp, hissing breath. She started rocking her hips immediately, not even giving her overstimulated body time to adjust to the intrusion. "Simon..." She moaned, marveling at the seemingly impossible fullness inside her.

"Kaylee!" Simon gasped out. All he could do was place his hands on her hips and hold on as she took him, until she moaned and pitched forward, leaning over him with her hands on either side of his head. Her breasts bounced temptingly in front of his face, and he leaned his head up to capture one taut nipple between his lips.

"Ta ma de!" Kaylee moaned breathlessly. Fuck me blind. She almost felt like she could go blind from the pleasure he was giving her, and she wouldn't have cared, as long as his face, in the throes of ecstasy, was the last thing she saw.

At the moment, Simon was having a similar thought, as he watched Kaylee's expression change when the angle of penetration changed from her movement and his cock rubbed over her spot. She squeezed and flooded around him, panting his name and random bits of endearments and swear words. "So beautiful." He groaned.

Kaylee leaned back then, supported herself on her hands. She was well beyond coherent speech except for his name. And even that became difficult to remember when his hands moved from her hips to her breasts, pinching her nipples almost roughly. She moaned and clenched her muscles around his shaft every time he did it. She could feel him getting thicker and harder inside her, and knew that neither of them would last much longer.

Feeling the first ripples of Kaylee's release, Simon slid his hands up to her shoulders and pulled her forward, so her clit rubbed the base of his cock with every stroke. He thrust up into her, as hard as he could, until she clamped down on him and came so hard she couldn't catch her breath to scream.

Gasping, Kaylee fell forward, slumping over onto Simon's chest. She could feel and hear his heart pounding, his low, loud groan as he pressed one hand against the small of her back, getting as deep as he could. She felt him swell and pulse within her, then finally felt the incredible heat of his release burst against her inner walls, flooding and warming her.

"Well." Kaylee panted softly, nuzzling Simon's throat. "Nothin' clumsy about that."

"Definitely not." Simon agreed, guiding her lips to his for a soft kiss, both of them still trying to catch their breath.

Kaylee smiled and lay her head on his shoulder, closing her eyes. Sweat cooled on her skin, but having Simon still inside her and wrapped around her was more than enough to keep her warm.

It was hard to say how long they lay there, just holding each other. Finally, Kaylee lifted her head just enough to see Simon still watching her, smiling. "Think anyone's looking for us?"

"I think by now they've learned that if they don't see or hear from us for a while, they shouldn't come looking for us." Simon pointed out.

"Or your sister tells 'em not to look for us." Kaylee added.

Simon groaned. "Don't remind me."

Kaylee giggled and pushed herself up off of him, wincing as he slipped out of her body. Simon tried to keep her in his arms as she stood up. "Just a second, sweetie. Gotta find us something to clean up with."

Watching her stand over him, Simon unconsciously held his breath. She looked so amazing, with her hair mussed, her skin still flushed and slightly damp. Her eyes had a sated gleam in them, and he noticed faint teeth marks on her shoulder, although he couldn't remember when he'd left them.

As she turned her back to him and started rooting through her toolbox, left open on the pilot's chair, she bent over, enough that he could see her wet, swollen folds, could see his semen dripping down the insides of her legs. He groaned softly. God, he could smell her, and that alone was enough to arouse him all over again.

When Kaylee found a mostly clean rag and turned back to Simon, she found him standing behind her. She gasped as he pulled her into his arms, pressing his swelling cock against her. Instinctively, she reached down and stroked him until he was fully hard and throbbing in her hand. The rag dropped from her other hand, forgotten as they kissed, as he slipped one hand between her thighs and two of his fingers penetrated her still-sensitive core.

Blinded by sensation, she barely noticed when he knelt down, pulling her with him, then removed his fingers from inside her and turned her around, guiding her to kneel with her back to him, supporting herself on her hands. She moaned, shaking with anticipation as he parted her bent legs and positioned himself behind her, pressing his chest to her back and sliding his lips over the back of her neck. Her last thought as he entered her was that she needed to be clumsy more often.

Simon sucked in a deep breath as Kaylee's body enveloped him tightly. He felt a shudder pass through her, heard her soft, hoarse mewl of pleasure when he pressed fully into her. Before, she had taken him, left him unable to do anything but watch her and enjoy. Now it was his turn. "I love you." He whispered in her ear, smiling when she clenched around his cock in response.

"Love you." Kaylee whimpered. "Oh, God, Simon...I love you."

He thrust harder at her words, knowing so well by now how to read her responses, knowing exactly what she needed from him. He slipped one hand around her body and lightly rubbed her clit with his thumb, applying more pressure when she squealed with pleasure. He carefully probed around her full core with his fingertips, then slid two fingers into her, moving them and his cock in a counter-rhythm, pulling sweet, soft moans from deep within her.

Kaylee felt her arms shake and knew she couldn't hold herself up much longer. She squeezed her thighs together, making him feel even fuller inside her. His fingers spread and stretched her while his thick shaft stroked over every sensitive spot. He was ramming into her now, taking her so hard she almost felt like she could snap in half. She bit her lip to hold back a scream, knowing the sound would echo in the small space. His chest rubbed against her back, their sweat mingling on their skin. He was tensing behind her, pushing his hips hard against her backside and working her clit harder with his thumb.

"Let go, Kaylee." Simon moaned breathlessly, urging her on. "I've got you."

His free arm wrapped around her waist, supporting her as her arms gave out, just as he kissed that spot at the back of her neck and lightly scraped his teeth over it, then laved away the slight sting with his tongue. That was all it took to send her spiraling over the edge into an intense, blinding climax. Her body tightened and pulled at his aching length as her sweet cries echoed inside his head. He followed her after only a few more thrusts, spilling into her clenching core, his release filling her and overflowing as his hips gradually stilled.

Groaning, Simon collapsed against Kaylee's back, trying to keep most of his weight off of her. After a minute, he rolled onto his side, keeping her spooned tightly against him. "That was..."

"Yeah." Kaylee breathed.

"You almost done in here?" Simon asked, looking at the tools scattered on the floor a few feet away from them.

Kaylee giggled and turned in his arms. "Forgot what I was doin' in here in the first place."
