Simon looked good without a shirt on. Real good.

No, Kaylee decided quickly. Good didn't even begin to describe how he looked. Watching him reach up over his head to tighten a bolt, watching the muscles in his back ripple under his sweat-dampened skin, she found her mind wandering far away from the engine.

Which, she had to admit, was really saying something about just how fine he really looked.

'Hell with this.' She thought, dropping the wrench she'd been holding. Crossing the room, she stood behind him for a moment, then slowly slid her arms around him from behind. He didn't seem at all surprised, which led Kaylee to suspect that he had been expecting her to make the first move. And that was just fine with her.

It wasn't their first kiss. In the past two weeks, there had been probably a hundred kisses, at least. But they hadn't let it get much further than just kissing, not while he was still healing. But the Alliance doctors who had patched him up had done a hell of a good job, and already all that remained of the gunshot wound that had left her believing, for a few terrifying minutes, that she was going to lose him, was a fresh red scar.

Simon wrapped one arm around Kaylee, pulled her tighter against him, as his other hand moved from her shoulder to the ladder next to him. Carefully, if not entirely gracefully, he guided both of them down to the floor, covering her body with his and sliding one hand under the back of her head.

This wasn't how he'd wanted their first time to be. He'd imagined it so many times. Imagined laying her out on his bunk, removing her clothing one piece at a time, kissing and stroking every new inch of skin that was revealed, then letting her do the same for him. He'd imagined exploring and worshipping her body with his hands and mouth until she was shaking and pleading, before finally making love to her.

But in that moment, he was having a surprisingly easy time letting go of that fantasy. Maybe he had just been holding back for too long. Or maybe it was just the fact that Kaylee didn't seem to have any complaints about their current location. Whatever it was, any idea of romance or propriety had vanished. He wanted her, and he was going to have her, right here and now.

Kaylee broke the kiss to catch her breath. "You sure you're up for this?" She panted.

Simon just grinned at her and glanced down to where their lower bodies were pressed together.

"You know what I mean." She giggled, wiggling her hips against his and delighting in the way his smile faltered and his eyes widened.

"I'm fine, Kaylee, I promise." Simon's voice was low and rough with desire. "Are you sure you're okay with this?"

Kaylee reached down between their bodies and cupped him through his pants, stroking gently but insistently. "What do you think?"

Groaning, Simon kissed her again, while his hands slid under her top, pushing it up just far enough to expose her breasts, then pulled back to take in the sight of her.

"God, Kaylee..." He said hoarsely. She was greasy, her hair was tangled, and her breath was coming in short gasps through swollen lips. She was starting to squirm and writhe, silently begging him to touch her, but he couldn't stop staring at her.

Finally, Kaylee grabbed his hand and placed it firmly on her left breast, moving under him as he responded, gently cupping and stroking her warm, soft flesh. Her soft whimper when he lightly pinched her nipple was all the encouragment he needed. He leaned down and captured her other breast in his mouth, sucking and biting softly at the hardened nipple, then stroking at her with his tongue.

"Simon!" Kaylee gasped. Her hips were now bucking hard against his involuntarily, and one hand was clutching at his shoulder so hard she was sure she was going to leave bruises on his skin. She ran her other hand through his thick hair, holding his head against her body.

She moaned in protest when he pulled away, but he kissed her softly and smiled at her as his hands slid down to her jumpsuit, already half-unzipped and tied around her waist. He paused and met her gaze.

"I ain't gonna stop you." Kaylee said huskily, licking her lips.

The material gave way easily, sliding down off of her hips. Simon looked back up at Kaylee, one eyebrow raised, when he realized that she wasn't wearing anything underneath. She just grinned right back at him, then sat up and kicked off her boots, slid one leg out of the jumpsuit, and sat back, leaning on her hands, waiting for him to make the next move.

He didn't keep her waiting for more than a heartbeat. Kneeling in front of her, he wrapped his arms tightly around her waist and pulled her against him, kissing her deeply as his hands slid over her naked back. One hand drifted around to the front of her body, between her thighs.

Kaylee whimpered softly when she felt the cold floor under her bare skin, but seconds later Simon pushed two fingers into her, and the last coherent thought she could manage was that some things were definitely worth getting a little chilly over.

Simon was trying to hold off, he wanted to take his time with her. But when he felt how wet she was, and her muscles clenched tightly around his fingers, his last thread of control snapped. Withdrawing his hand, he gently pushed her thighs further apart, just as she undid his pants and pushed them and his underwear down just far enough to get at what she wanted. Curling her fingers around him, she carefully guided him to her, then looked up at him, into his eyes.

"Finally." She couldn't be sure if she said it out loud or not, but within seconds it didn't matter, because he was inside her and she couldn't hear anything other than his soft groan as she stretched around him, then clasped him tightly. Her vision blurred and she couldn't think, could barely catch her breath. Then he started moving.

"I'm sorry." He panted against her ear. "I can't wait."

She wanted to tell him that it was okay, that she was right there with him, but when she opened her mouth, all that came out was a low, broken moan. She wrapped her legs around him, dug her heels into his lower back as she met each thrust. She could already feel her release building deep inside her, and she wanted to hold off, wanted it to last longer, but it had been way too long, and she was way too pent-up. She could feel herself getting wetter with every stroke, could feel something deep inside her tightening.

Simon kissed her again, then pulled back, tried to catch his breath as his lips moved lower, down to her throat. He bit down lightly on her collarbone, and she shrieked and squeezed tight around him. He was so close he couldn't even maintain a steady rhythm any more, and he had to make sure she was ready. He slid one hand between their bodies while his lips and tongue grazed her breasts.

His thumb rubbing against her clit was the last straw, and she bit down on his shoulder to muffle her scream as she broke under him, her back arching and her entire body freezing up, then going limp as she clenched and spasmed around him. She closed her eyes and listened to his shout as he came in her, felt his warmth inside her and his weight on top of her.

After a few minutes, he raised his head and looked down at her, supporting himself with his arms on either side of her head. He was blushing furiously. "Kaylee, I..." He trailed off when he saw her smiling at him, that amazing smile of hers that never failed to melt him. She was blushing, too. "Oh, so now you're shy?"

Kaylee giggled and swiped at him playfully. "Been a long time." She admitted.

"Yeah, I'm sorry about that." Simon told her, brushing his lips over hers.

"Don't be." She whispered against his ear. "It was worth waiting for." She felt his smile against her skin. When he started to move off of her, she tightened her arms and legs around him. "Not yet."

"I'm heavy." He protested uselessly, even as he let her pull him back down to her. "And the floor's freezing."

"Guess you'll just have to keep me warm, then." Kaylee insisted. Truthfully, she couldn't even remember being cold. Her breath caught in her throat as Simon started kissing her again and running his hands over her body.

As he placed gentle kisses across her chin, slowly moving to where her neck met her jaw, she let her eyes drift up to the ceiling, to the hatch above them. And froze at what she saw there.

"Oh...my...God."
