Jayne rolled off of River, panting. It was three in the morning and they'd just gotten through their second round of sexin' in River's bunk. They'd been sneaking around for two weeks now, switching between Jayne's bunk and her own every other night.

"Gorram, girl, where you learn that? You sure you ain't done it with a man before?" Jayne wiped the sweat from his brow, slowly gathering the strength in his legs again.

"You were thinking about it yesterday. You were pleasuring yourself." River was breathing hard, moaning between breaths, her whole body still burning hot. She still had not gotten comfortable with not being able to sleep next to Jayne. She knew it was impossible. Simon couldn't find out about Jayne yet.

River gasped in surprise as Jayne pulled an arm under her waist, tugging her heated body close to his. She read his thoughts a bit, and smiled, nuzzling her face into his strong chest.

"This sneakin' around shit's gettin' tired ain't it?" Jayne looked to River's eyes, still shining with that relaxed, "just got good and sexed" look.

"It's... He'll be very upset when he finds out. Want you to myself for awhile." Her eyes took on a new tone, one of compassion and innocence. "Private."

Jayne just nodded and slipped his hand down to River's wet slit, sliding two fingers deep within her. Her moan was soft, almost unnoticed, like a sigh heard through a heavy wind.

"Yeah, I like keepin' ya quiet sometimes too." His fingers started a slow, harsh pace, making River's body pliant in his arms. "But damn, River... Sometimes I wish I could just take ya in the middle of the day. Everyone watchin' as I carry ya off to my bunk."

River was shaking at his words, particularly the use of her name, rough and tumbled, falling from his lips. He had used it before during sex, but it was rare; an occasional glimmer of emotion he only let slip in the throes of passion. He wasn't ready to admit it with real words, clothed and public. River had learned to be patient; time would give her what she wanted when it was needed.

Without warning, Jayne's mouth covered River's. For someone who didn't kiss girls on the mouth, he seemed willing, even eager, to kiss River an awful lot. The kisses only made the passion swell to deafening volumes within her. The way he kissed was violent, without drawing blood.

Well, there had been blood once, a week ago, when his teeth had bit down on her lower lip. River had just cried out with excitement as Jayne sucked the crimson from the wound.

Now River was climbing on top of Jayne's broad body, his fingers still churning within her. She bit almost painfully at Jayne's lower lip, causing him to buck his hips at her. She grabbed his wrist hard, yanking his fingers from her and lowering herself onto his already weeping erection.

Jayne groaned excitedly at the feel of her muscles clamped around him. She hadn't done this before. Always had him on top. But now she was grinding down on his length like she was a pro, gasping and crying out like she'd never had sex before tonight. Jayne just watched her, his hands gripped tightly to her hips.

Sweat trails dripped between River's small breasts, her back arched, letting the sweat fall all the way to the neat nest of curls above where their bodies met. Jayne cursed, the sight of her and the feel of her almost blinding him with pleasure. River just keened on top of him, occasionally begging God for release.

Finally they both came, violent torrents running through their bodies, pooling within River's core. River breathed hard a few times, then lay spent on Jayne's heaving chest. After a few minutes, Jayne slid her off of him carefully, his soft cock falling wetly out of her. She was sleeping deeply, only moaning to protest the lack of him under her before rolling over. She curled up with one of his pillows she'd stolen from his bunk the night before.

Jayne dressed quietly, then took a moment to pull River's blankets over her nude form before leaving quietly. He went across the way to his own bunk, opening the hatch as silently as he could. He undressed quickly, soaking a washcloth in warm water from the sink to clean his length of any evidence of sex. Jayne pulled on a pair of sweatpants and lay in bed, blankets tugged over his body, trying to breathe in the ghost scent of River's body still on his.

River groaned a bit, hearing the crew all the way from her bunk. They were talking amiably over breakfast, making jokes about Kaylee and Simon coming to the table, thoroughly sexed.

River pulled on one of her more simple dresses and a new pair of underwear, regarding the pair Jayne had torn last night in his fervor with a grin. She climbed out of her bunk after brushing quickly through her hair, then danced her way into the galley.

She was pleased that Jayne was already at the table. Usually one or the other made sure they were at breakfast on time to avoid suspicion. Simon looked carefully at his sister as she sat down.

"Mei mei, you've been tired a lot lately, are you feeling okay?"

"I'm fine. Just stay up late doing stuff. Get caught up drawing or reading. Sometimes dancing in the cargo bay."

Jayne bit back the opportunity to mutter "Stay up late gettin' more thoroughly sexed than you, more like." River looked up at him at the thought, giving him a look that clearly told him if he said that, he'd be in trouble. Jayne just grimaced and finished off his plate, putting it in the sink when he was done.

Once the meal was finished, River went to the cockpit, checking out all the navigation. Mal came in a few minutes later, sitting in the chair next to her.

"You have been a mite tired lately, lil albatross." He checked the ETA and looked over at River. "I'm startin' to get concerned my own self."

River brought her legs up to her body, wrapping her arms around her knees. "I'm fine. Been better since Miranda. I finally know what I'm saying. What I'm thinking."

"Well that's good, little one. I just don't want it to get in the way of your duties."

"It won't. Just get ideas in the middle of the night. Have to work out the problems. 'You can learn all the math in the 'verse...'"

"And I'm right sure you already know all the math in the 'verse." Mal got up and kissed the top of River's head gently. "Just be careful with your endeavors, Lil 'Tross. Just be careful."

*****

"Mmm... That was real nice, Simon." Kaylee lay spent in bed, Simon's sweaty body under hers. He wrapped his arms around Kaylee, kissing her lovingly.

"Very nice." Simon couldn't think of anything more coherent to say than that, still caught up in the last waves of his orgasm.

They both lay there, their breathing slowly returning to normal, the sweat clinging to their bodies evaporating or absorbing back into their skin.

"I should get to work in the engine room soon, sweetie." Kaylee traced the arch of his neck with the tip of her tongue, as though she had no intention of leaving the bed any time soon.

Simon moaned gently, holding onto her tighter. "Doesn't seem like you want to leave just yet." He grinned.

"Never wanna leave ya. 'Specially when you're all naked and underneath me." Kaylee rolled her hips, moaning with pleasure and pride at the way he hardened almost instantly within her.

Simon groaned, rolling them both over so that he lay on top of Kaylee. He put his weight on his hands and started thrusting slowly, savoring the feel of her inner walls as he pushed and pulled between them. He loved this, making love to her slowly and gently until she cried out in ecstasy.

Kaylee was content to just moan and writhe beneath Simon's strong body for now, recording into her memory the way he felt churning inside her. She sighed his name gently and rolled her hips at every inward thrust, mewling softly between each breath she took.

"Simon... Wo de tian you feel so good." Kaylee's back arched a bit, the feel of him inside her overwhelming. Simon leaned down and kissed up the valley between her breasts, letting the flat of his tongue ghost over her throat before kissing her soundly.

"You feel even better, baobei." He groaned as Kaylee tightened around his hard length, making him thrust faster a couple times before going back to his slow pace. "So good."

Neither of them were intent on climax. They were just enjoying the feel of each other, drawing out the pleasure they gave and recieved as long as they could. When they finally tumbled into their releases, they felt like they were floating above Serenity, lost in the Black together.

Suddenly Mal's voice came through the com, breaking through their reverie.

"Kaylee, stop humpin' the doc and get your butt into the engine room. We wanna get to Ita Moon, you best make sure everything's workin'."

Kaylee got up quickly and went to the com. "Shir ah Cap'n. Be there in a couple minutes." When she released the button she pouted over at Simon in apology. He just nodded, knowing she had to go.

"I'm just gonna ignore the fact that you're pantin' like a dog in heat, Lil' Kaylee. Just get up there once you're dressed." The com clicked off and Kaylee frantically looked for something to wear under her coveralls. Simon got up from bed and calmed her by putting his hands on her shoulders.

"Relax, Kaylee." He kissed the back of her neck gently. "I probably have to check on things in the infirmary anyway, xin gan. Just take your time. It's obvious the captain knows what we were doing in here."

Kaylee grinned as she slipped a shirt and some panties on before grabbing her coveralls.

"Yup, he knows." She kissed him deeply and passionately, breaking the kiss almost as quickly as she'd started it. Gotta go, hon. Come see me when ya get the chance!"

Jayne had done everything. Cleaned and polished all of his guns. Even polished Vera three times. Nothing he did could get his mind off River. He'd been wanting her all day, since he saw her at breakfast. He went to his bunk to release some of the pressure that had built in his pants.

When he'd climbed down and closed the hatch, he turned to find River already naked in his bed. Her hand had slipped under the covers, and he could only see the movement of them as they slid in and out of her core. He covered the space between himself and the bed and tore the sheets off her.

River's hand only moved more quickly as he pulled the bedding away from her body. Jayne had questions, but he didn't ask them. Instead he just undressed in record time, tearing River's hand away as he climbed into bed, replacing her fingers with his mouth.

River had a hard time not letting out a scream. She just bit her lip and moaned deep in her throat, her body arching off the bed. Jayne plunged two of his own fingers within her, his mouth sucking fervently on her clit. River came almost instantly, her whole body thrashing as the pleasure ripped through her being.

Jayne crawled awkwardly over River's shaking body and slid his thick length inside her with one long, fluid movement. He covered her mouth just in time to muffle the scream she couldn't control, then started thrusting into her recklessly.

River's inner walls were fluttering around Jayne so tightly he thought his eyes might cross at the pleasure. As it was he was already feeling that blinding, white flame shock through him, so close to release that he couldn't hold back. He slammed into her even faster, burying his face in her neck to muffle his own outcry as he spilled himself into her wet heat.

River came silently after him, her whole body tense, her mouth open in a soundless cry. They fell back onto the bed, panting loudly, slowly recovering from the force of their climaxes.

"Couldn't hold back. Knew they wouldn't find us." River spoke between gasping breaths and moans, her body slick with sweat.

"Gorram, girl. You gotta do this more often when ya know it's safe." Jayne rolled his hips a couple times, moaning with River as his still hard length moved within her.

"Hasn't been safe 'til now. Gotta go back to the cockpit." She rolled them both over, landing roughly on top of Jayne. He groaned as he slid deeper inside her and grabbed her hips.

"Already?" He slid his hand down to where their bodies joined, roughly manipulating the sensitive flesh there.

River moaned loudly, her own hips rolling. She nodded slowly, trying to compose a coherent sentence as Jayne's fingers remained unrelenting. "Have to get back. Mal will come looking for me soon... Oh God..." She came suddenly, her body tremoring.

Jayne pulled River close, moving her hips as she came. He whispered hoarsely into her ear. "Don't want you to go. Need ya just one more time." River's entire body was pliant and responsive. She moaned softly and started moving her hips of her own accord.

"Can't... Going to come soon." She groaned a little as the double meaning of her words rang true. She could feel Mal starting to look for her, while she could feel Jayne's orgasm rising in his body.

"Promise I'll come 'fore he does." Jayne grunted as he started spilling his seed without warning. River bit her lip to keep from crying out, her back arching at the feel of Jayne's length pulsing within her.

As soon as he was done she got off him quickly, wiping herself off and putting her dress back on. River kissed him quickly and ran out of his bunk before Mal could come down the crew dorm hallway.

Jayne was left panting hard, his softening cock still weeping. When he finally came to his senses, he sat up and found his pants and pulled them on. He vaguely heard River telling Mal that she'd just been writing some things down in her own bunk.

Jayne put his shirt back on and climbed out of his bunk, finding Mal about five inches from his face.

"Well now, Jayne. You mind tellin' me what exactly it is you're doin' with my pilot?"

"Matter of fact, Mal, it ain't somethin' I'm willin' to discuss with ya."

Mal grabbed Jayne by the shirt and pushed him violently into the door of his bunk.

"Oh, I believe you ain't got a choice as to whether you're discussin' this with me." He pushed Jayne harder into the wall. "Now if you don't tell me guai guai long de dong is goin' on, I'm going to be givin' the doc some guns and tell him what you've been doin' to his little sister."

Jayne sneered a bit, then noticed River peeking out from behind the wall, frightened.

"Guan ni zi ji ze shi, Mal. River's over there behind ya, scared shitless. Don't ya think what she does with her time is her own business?"

"It becomes my business when I think that she might be doin' somethin' that ain't good for her. And ruttin' you ain't good for anyone, least of all her."

River yanked Mal back and pushed him against the opposing wall. "My decision. I'm an adult now. If I knew this was a bad idea in the long run, I wouldn't have started it."

Mal grabbed her shoulders gently. "I'm worried about ya, Albatross. Jayne ain't exactly boyfriend of the year in any planet system."

"Doesn't mean he's bad for me. Don't tell Simon. He needs to find out on his own." Mal looked at River, her eyes shining with tears. She needed this secret kept, despite the fact that Mal was completely against the relationship.

He sighed and shook his head in resignation. "Alright. I won't tell your brother. But gorrammit, River, this ain't exactly an ideal situation."

River kissed Mal's cheek gently and smiled, then walked off to the cockpit, leaving him alone in the hall with Jayne. Mal punched him once, hard.

"You hurt her, I will kill you." He didn't wait for an answer before he left and went into his bunk.
