"When are we going to be landing?" Book questions Mal.

Mal glances up from gun he's cleaning to see Book, Kaylee, Inara and Simon standing by the door. "Bout an hour or so."

"We gonna be able to go to town?" Kaylee asks.

"Ain't really a town where we're goin', little Kaylee." Mal replies. "Pretty much just gonna be us and the folks we're meetin' with. But we gotta drop the cash off on Persephone so you can get off there."

"What are we transporting anyways?" Simon questions. "You never did tell us."

"I got no clue and ain't sure if I want one." Mal answers.

"Can we at least get off the boat?" Kaylee asks Mal with big eyes.

"I don't think so, little Kaylee." Mal replies, refusing to look at her. "Badger warned me to watch my back; this job is gonna go ugly. I want everyone stayin' on the boat till we get back on, dong ma?"

"Yeah." Kaylee agrees with a pout. "How long we gonna be on Persephone?"

"Couple days." Mal answers. "Nara's gotta full schedule and I got a couple meetings lined up."

"Looks like another fun adventure in sitting." Simon mutters.

"Cap'n, can't he and River get off the boat?" Kaylee asks. "We can disguise em and keep em separate."

"I'll think bout it." Mal replies. "Speakin' of River, where is she?"

"Where else?" Simon answers. "With Jayne."

"She's helpin' him get the mule ready." Kaylee explains.

"Yeah, and I'm guessin' a lot of work is gettin' done." Mal mutters. "How's her belly lookin'?"

"Good actually." Simon answers. "I'm going to take the weaves out in a few days. She's healing very well."

"That's nice to hear." Mal replies. "I think it's bout time I checked on Jayne's progress and most likely, separate them two."

-

"Darlin' I'm supposed to be workin'." Jayne groans against River's mouth.

"But you are working." River says as she grinds down onto him. "Your hands are very active." River pushes onto his chest and forces him to lie down on the backseat of the mule.

"They sure are." Jayne agrees, his teeth tugging on her bottom lip. His hands massage her breasts through the fabric of her dress.

"Skin." River moans. "You must touch skin."

"We're in the gorram bay, sweetness." Jayne growls. "I ain't havin' somebody walkin' in and seein' you naked."

River sits up with a thoughtful look on her face. Then with a happy smile, she stands up to grab his coat off the front seat where he set it earlier. Before Jayne can comment, she pulls her dress off and then puts his coat on over her almost naked body. "Now you can touch skin." River says as she straddles his body again. "And nobody but you will see."

Jayne's hands automatically snake inside his coat to gently rub her bare belly. "You're just all kinds of smart." Jayne murmurs as his fingers trace over the healing cut on her belly. His hands glide up her sides to cup her breasts. She moans and arches into his hands. "Why don't ya just bend on down here, little darlin'?" Jayne says huskily.

River slides up Jayne's body a little and then eagerly leans over until her breasts are floating above Jayne's mouth. "I would like you to taste me now."

Jayne nips at the side of her breast, laughing when she squeals, before sucking her nipple into his mouth. The sides of the coat hang down to surround him, dimming out the bright lights of the bay until all he can really see is the milky skin above him. He drags his teeth across the hardened nub and groans against her mouth when she rotates her body down onto his. His mouth sucking greedily on her nipple, he slides his hand down her body to cup her heat.

"Oh…" River squeals at the surprise touch. His fingers pet her through the fabric of her wet panties and she can't hold back the pleasured gasps that leave her mouth. He presses the cloth firmly against her clit and rubs the fabric back and forth over her aroused flesh. With a frustrated moan, she reaches down to pull the fabric of her soaked panties to the side. "Please Jayne, inside. I must feel you inside."

Jayne coats two fingers with her juices and the forces them inside her warm body. He bites and sucks at her breasts and his fingers pump forcefully inside her. "You can't scream, baby." Jayne says as he works her body. "It'll echo through the gorram boat."

"Have to." River protests as she feels little shocks of pleasure shoot through her body.

"Can't." Jayne replies. Jayne removes his fingers from her body and pulls away from her breasts.

"No, Jayne, you mustn't. " River pants, her eyes brimming with tears. "Please don't stop. I will try not to scream."

"Hey, now." Jayne says as he moves them onto their sides, River's back pressed against the seat. "Ain't stoppin', just gettin' into a better position." His hand burrows back between her legs as he presses his mouth against hers. "Need ya to spread your legs, baby girl."

River moves her leg up to rest on the seat behind her leaving her body completely open.

"That's my girl." Jayne growls as he plunges his fingers back into her eager body.

River moans and whimpers against Jayne's mouth as her hips ride his fingers.

Jayne breaks the kiss so he can watch the pleasure float across her face. One of the most arousing things he's ever seen is her face as she cums. He's guessin' cause of what was done to her, she's got no control over her reactions cause in all the times he's had sex, he's never seen pleasure fill a face the way hers does. He brings his thumb up to press against her clit as his fingers pound into her.

River feels the familiar tightening in her belly and buries her face into his neck. When he pinches her clit between his fingers, she bites down on his neck to smother her scream.

Jayne groans loudly when her teeth break his skin. His fingers work her through her orgasm as his other hand rubs soothingly up and down her back. "You okay, darlin'?"

"Mmmhmm." River murmurs against his neck. She licks the wound a few times before moving up him to kiss his mouth.

Jayne can taste his blood on her lips as he slides his tongue into her mouth.

"I want to taste you." River says against Jayne's mouth.

"You are." Jayne replies.

"Not here." River reaches up to touch his lips. "Here." Her hand drops down to cup his cock.

"Jesus." Jayne groans as she forces him onto his back and crawls down his body to rest her elbows on each side of his hips. She quickly unfastens his pants and pulls his hard cock out.

River studies Jayne's cock for a few moments before grasping it firmly in her hand. Deciding the most logical place to start would be the top, she drops her mouth to kiss the head of his cock. Liking the groan that leaves his mouth, she sucks firmly.

Jayne's eyes close and his hands clench the seat underneath him. He knows he's not gonna last long, specially if she keeps suckin' at his tip like she is. His hips buck when her teeth nip him gently and he groans again when she wraps her tongue as far around his shaft as it will go and slides it up and down.

River likes the taste of his cock in her mouth and the feel of him under her tongue. Waiting to taste his release in her mouth, she moves back up his cock to take as much of him into her mouth as she can fit. He fills her mouth completely, almost making her gag.

Jayne groans loudly at the feel of her warm mouth around him. When she starts sucking him, her mouth firmly milking his cock, his hands fist in her hair as his balls start to tighten. Her name leaves his mouth in a shout as he bucks into her mouth.

River swallows Jayne's release greedily, liking the taste of him in her mouth. When his hands loosen in her hair, she gives his cock one last kiss before crawling up his body to rub her cheek against his.

Jayne slips his arms inside his coat and wraps them around River. With a playful growl, he attacks her neck with his teeth and tongue.

River giggles at Jayne's playful attack and reaches up to grab his face. Holding his face between her hands, she rubs her nose against his before moving down to kiss him softly.

"Where the gorram hell is he?" Mal's voice echoes through the bay. "I ruttin' told him to get the gorram mule ready and he ain't even in here."

"Gotta let me up, baby girl." Jayne says softly to River.

River kisses Jayne again and then slides against the seat so that he can get up.

Jayne stands up, his back to the crew and quickly tucks himself back inside his pants.

"Jayne, what the hell are you doin'?" Mal questions. "I thought I told ya to get the mule ready."

"I am, cap." Jayne replies as he zips up his pants.

"Where's River?" Simon asks. "I thought she was with you."

River stands up beside Jayne and smiles happily at her brother. "Right here."

Simon stares at River with a confused expression on his face. "Are you cold, mei-mei?"

"No." River answers, her eyebrows furrowed with confusion. "It is rather warm in here."

"Then why are you wearin' Jayne's coat?" Mal questions and then pauses thoughtfully. "You do got clothes on under it, right?"

"She has panties on." River replies. "But her dress is on the ground."

"Ai ya! Hwai leh!" Mal yells in disbelief. "My mule? You was ruttin' messin' round in my mule?"

Jayne ignores Mal's tirade and jumps out of the mule, his hands reaching back in to heft River out. "Here ya go, darlin'." Jayne says as he hands her dress to her. "Now, turn around and slip it on under the coat."

Jayne uses his big body to block everyone from seeing River as she slips back into her dress. When she pushes the coat off her bare shoulders, Jayne moves up right behind her to help her pull the straps back up her arms. He absently presses a kiss to her shoulder before turning her around to make sure her dress is adjusted correctly.

"Hey, pissed off captain here." Mal yells. "I wanna know what would ruttin' possess you to mess round in my mule."

"Weren't like we planned it Mal." Jayne replies. "Just kinda happened."

River walks around Jayne and moves to stand in front of Mal, looking up at him with big eyes and a slight pout. "It was her fault; she distracted Jayne from his work." River whispers tearfully. "Are you very mad at her captain daddy?"

Mal groans and looks away from River to glare at the smirking merc. "We done decided that ain't gonna work on me, little witch." Mal says.

River sniffles loudly.

"And no, I ain't mad at ya." Mal says quickly, not wanting to see her cry, even if he knows she's just playin' him. "Just want you two to find more appropriate places when you….distract Jayne, dong ma?"

"She promises to try." River replies and before he can yell at her, she reaches up to peck him on the cheek. "She is glad you are not mad at her." She then skips over to give Jayne a kiss.

Jayne snakes an arm around River's waist to hold her against him. "I recall sayin' I don't like you kissin' on the captain." Jayne growls against River's mouth.

River pulls back and looks up at Jayne. "You must not be jealous of captain daddy." River says. "I have no desire to lie with him."

"Don't change nothin'." Jayne replies. He kisses her forehead, turns her around, and smacks her gently on the ass. "Why don't you go and hang out with Kaylee while I finish get the mule prepped?"

River rubs her ass, glaring playfully over her shoulder at Jayne. "Come on Kaylee, let's go play with the engine."

"Don't even ruttin' think bout it." Jayne growls.

River sticks her tongue out at him before grabbing Kaylee's hand and pulling her out of the bay.

"Don't want her round the engine." Jayne tells Simon.

"Why are you telling me?" Simon replies.

"Cause you're her ruttin' brother." Jayne says.

Simon laughs. "You don't actually think she's going to listen to me, do you?" Simon replies. "The only person she even remotely listens to is you and I don't think she really does then."

"Hey, she listens to me." Mal protests.

"Sometimes." Simon agrees. "And sometimes she's able to manipulate you into doing what she wants you to, just like she did a few moments ago."

Mal turns to glare at him. "Why don't you go and get the infirmary ready for us?"

"That's probably a very good idea." Simon replies as he turns to leave the room. "Somebody's bound to get shot."

"Jayne, I want the mule cleaned out after the job." Mal orders. "Till then, you're ridin' in the back."

-

"Whatcha doin'?" Kaylee asks Simon.

"Seeing how much medicine we have left." Simon answers, turning around to smile at the mechanic. "What are you doing? I thought you and River were 'hanging' out."

"She said she needed to be alone for a while." Kaylee replies. "I'm guessin' she's in her room."

Simon sighs heavily. "She does this every time they go on a job." Simon tells Kaylee. "I think she can feel what they're doing and doesn't like to be around them when they come back."

"Oh." Kaylee replies. "Should we go look for her?"

"No, I think we should let her be." Simon says. "I really do think she just wants to be alone. She usually comes out after a hour or so."

Inara pokes her head into the infirmary, smiling at Kaylee and Simon. "They're on their way back." Inara interrupts their quiet conversation.

"Hey, Nara." Kaylee says. "They get hurt?"

"They didn't say." Inara answers. "Zoe just told Wash to get ready to leave."

"So most likely they did." Kaylee replies. "Come on, Simon, we should go see the damage."

Simon takes the hand Kaylee is holding out and follows her out of the infirmary. "Where's Book?"

"He's waiting in the bay." Inara answers. "You know how worried he gets."

They make it to the bay right as the mule drives in. Jayne jumps out and closes the bay door while Zoe runs over to the intercom to tell Wash to take off.

"Who's hurt?" Simon questions Zoe.

"Mal." Zoe answers. "But it ain't really nothin', just a scratch."

"Yeah, I'm fine, doc." Mal says as he jumps out of the mule, his hand held against his shoulder.

"Jayne, you're not injured?" Simon questions the merc.

"Naw." Jayne answers. "A few scratches but nothin' to worry bout."

"What happened?" Book questions.

"What else?" Mal replies. "They didn't wanna pay for the cargo and decided the best way to show this was to try and kill us. We made em see the error of their ways."

"We shot em." Jayne states simply, his eyes running over the bay. "Where's River?"

"We don't really know." Simon answers.

"You what?" Jayne replies angrily. "What the gorram hell do you mean you don't know?"

Simon takes a step back from Jayne. "She's on the boat, hiding somewhere." Simon assures the irate looking man. "I don't know if you've noticed, but she always hides while you're on a job. She usually comes out after an hour or so."

"Why?" Book questions.

"I'm not positive, but I think that she can feel what they're doing and doesn't feel comfortable being around them afterwards." Simon answers.

"I'm gonna go look for her." Jayne says, stomping out of the bay before they can say anything.

"I need Kaylee in the engine room." Wash's voice echoes through the bay.

"Kaylee, you and Book go to the engine room." Mal orders. "Zoe, you go see if Wash needs help. Nara, you can help the doc patch me up."

Simon follows the injured captain out of the bay, looking over at Inara with a smile. "Looks like this part of the plan happened as it was supposed to."

"Pardon?" Inara replies, slightly confused.

"Wash is flying us to safety from whoever might be chasing us." Simon explains. "And I'm about to patch up Mal after he got shot. All in all, this part of the plan worked."

Inara smiles when Mal turns his head to glare at Simon. "It always does."

-

Jayne stomps through the boat towards River's room, deciding it's the most logical place for her to be hidin'. He don't like the thought that she don't wanna be round him after he's killed; it don't fit anything she's done said bout her past. He knocks on the door and when she don't answer, he slides the door open and walks in, closing it behind him. He hears the shower runnin' and sighs with relief, knowin' she's just takin' a shower. He starts to sit on the bed when he hears a deep, painful moan from behind the shower door. Without thinkin' twice, he throws the door open.

"Wuo duh ma." Jayne mutters, his body hardening instantly at the sight of River. She's sittin' back against the shower wall, water pounding on top of her. Her legs are bent and spread wide, three fingers pumping forcibly in and out of her body, tears running down her face.

"It's worse." River cries as she pumps her fingers harshly. "It never hurt this much before; was never this strong."

"Baby, I don't understand." Jayne says as he walks towards her. His hand reaches under the flow of water to find it ice cold. He turns it off and squats down so that he's face level with her.

"I can't make it stop burning." River explains as she reaches up to pinch a nipple. "Please, Jayne, help me."

"Baby, I don't know what you want me to do." Jayne says softly.

River doesn't answer, instead she throws her legs over his shoulders, forcing him do sit down to keep from falling.

Jayne grasps River's smooth, wet legs and grows harder, something he didn't believe was possible. "Baby, whadda want me to do."

"Help me." River pleads, using her legs to pull his face towards her aching cunt. "Make me scream."

Jayne finally realizes what's wrong with her and with a growl, spreads her folds and sucks her clit into his mouth. He thrusts two fingers in time with his suction on her clit. He knows that she needs to cum, he can tell by the tension in her body. He wonders how long she's been in here, tryin' to get herself off and his arousal tightens painfully. He uses his teeth to scrap against her aroused clit and is rewarded when she screams his name loudly. His fingers work her gently through her orgasm and when her body stops pulsing around his fingers, he pulls them out and stands up. Grabbing a towel off the ground, he picks River's panting body off the ground and carries her out of the bathroom.

Jayne sits down on her bed, ignoring the feel of his now wet clothes. Cradling her against his chest, he uses the towel to dry off her body as best he can. "Wanna tell me what that was bout?" Jayne questions. "Not that I minded or nothin'."

River sits up and straddles Jayne's lap. Pushing her wet hair over her shoulder, she then wraps her arms around his neck. "I can feel you." River whispers. "Feel the blood lust pulsing through your body; it makes me throb."

Jayne groans and holds her hips still, his control almost gone. "You do this a lot?"

"Masturbate?" River replies, trying to buck her hips against his.

Jayne nods.

"Yes." River answers. "Every time you go on a job, it burns through me for hours. Simon believes I don't want to be around you but nothing is further from the truth. I have to hide so I can releave the tension." River then pulls his mouth down to hers to kiss him hungrily as her hands move under his shirt to play with his chest.

Jayne breaks the kiss with a groan and pulls her hands out from under his shirt. "Darlin' we can't do this, not now." Jayne groans.

"Why not?" River questions as she runs her mouth down his neck.

"I'm not gonna be able to hold back." Jayne replies. "I ain't got the control."

"Don't want you to hold back." River says. "I just want you."

"You sure bout this." Jayne asks.

River just snakes her hands between them to unbutton his pants.

Jayne captures her small wrists in his hands and pulls them away. "No, baby."

River looks up at him with hurt eyes. "You do not want me?"

Jayne laughs.

Tears fill River's eyes as she tries to move off Jayne's lap. When his arms tighten around her, she tries to push away from him.

"Baby, stop." Jayne says as he tries to catch her flailing limbs.

"No." River growls. "You do not want me."

Jayne flips them over and holds River against the bed, her arms held above her head. "I want you more than I've ever wanted anything in my whole gorram life." Jayne growls down as he presses his rock hard cock against her belly. "The fact that you questioned it is why I laughed, dong ma?"

River smiles happily up at him. "Make love to me." River whispers as she wraps her arms and legs around him.

"Not here." Jayne says as he stands up with her attached to him. He grabs her blanket and wraps it around them. "Most likely, Kaylee, your brother, or Mal would walk in within 5 minutes."

"Where are we going?" River questions as she rubs her face against his.

"My bunk." Jayne answers. "And we ain't leavin' for a long, gorram while."

River giggles and licks Jayne's cheek.

Jayne walks through the halls, groaning occasional when River nips his neck or bites his earlobe.

"Is she okay?" Simon questions worriedly, rushing out the infirmary to stop Jayne as he walks by.

"She's fine." Jayne answers curtly as he walks past the doctor.

"Jayne, where you goin' with my little genius?" Mal questions.

"She ain't yours." Jayne growls. "And we're goin' to my bunk."

Mal watches them leave and can't help but smile. Things are gonna get mighty interesting round here and Mal loves nothin' more than some drama.

-

River drops the blanket to the ground and looks around Jayne's bunk with curious eyes. They've never been down here together; Jayne wouldn't bring her down here. She understands now; it's too private. Her eyes catch the naked women on his walls and she turns to look at him with a glare, her fists resting on her hips.

Jayne knows she's pissed bout somethin' but can't really focus past her naked body to figure it out.

"I cannot have sex with you if they are watching." River says, waving a hand to the pictures.

"Can't this wait till later?" Jayne questions as he steps forward to grab her hips.

River shakes her head wildly. "No." River replies. "I can't if they are still up there."

"They're just pictures, darlin'." Jayne says. "Don't mean a gorram thing."

River traces her hand over Jayne's chest. "They're prettier than me." River whispers. "And have bigger breasts and aren't broken girls with broken brains."

Jayne cups her face in his hands. "You're beautiful, baby, don't ever doubt that." Jayne says huskily. "And they might have bigger tits but I like yours." His hands cup her breasts to illustrate his point. "And you ain't broken, not no more." His hands slide down to cup her ass, pulling her against his cock. "Why don't I just prove how much I want you." He picks her up and deposits her on his bed before she can respond. He drops the guns still strapped to his body to the ground and kicks off his boots. His shirt and pants come off next and then he sits down on the edge of his bed and runs his fingers up and down River's body.

"Mmm." River hums happily as she wiggles around on his bed. "No holding back, Jayne. You must touch me."

Jayne lies down next to her and leans over to kiss her deeply. He runs his hand up and down her sides before cupping her right breast. His thumb rubs over her nipple as his other hand slides down to test her body. Her legs spread eagerly and he pushes two fingers into her wet, warm heat. Her body molds tightly around his fingers and he knows he ain't gonna be able to wait long till it's his cock inside her. But for now, he just pumps his fingers shallowly, tryin' to get her as worked up as he can.

River moans against Jayne's mouth and pushes against his hand, trying to get him to move deeper. "More." River pants against his mouth. "Moremoremoremore. Need more, Jayne." She throws a leg over his hip, baring her body completely to his fingers.

Jayne kisses River's panting mouth, trying to soothe her distress. His thumb rubs her clit evenly as he works another finger inside her.

River groans at the feel of her body stretching around his fingers. "Feels tight." River pants.

"You are tight, baby." Jayne groans. "So gorram tight."

"Full." River mewls. "I'm not full. I need you to fill me."

"Oh, I will, baby." Jayne growls huskily. "Just gotta make sure you're properly stretched first is all."

River slams her hips against his fingers, pushing them deep inside her. "I'm stretched."

Jayne pulls his fingers out with a growl. He sticks them in his mouth as he stands up, sucking her juices off them. His hands then push his boxers off and he crawls down to straddle her body.

River wraps her legs around his hips and pulls him closer until his cock is posed at her entrance.

"Hold on, baby." Jayne groans. "I gotta find some protection."

"Inara gave me a birth control shot the morning after the first time we slept together." River says. She tightens her legs around his hips until the tip of his cock is inside her. "It's time to come inside now."

Jayne rests his weight on his arms as he pushes slowly inside her. He closes his eyes when he's completely inside her, trying to give her enough time to adjust to his size.

River flinches at the first initial stretching and pants as she adjusts to his size. After a few moments, she rolls her hips against his and moans at the little shocks of pleasure-pain that flash through her body.

Once she rolls her hips, and he knows she's ready, Jayne pulls completely out of her body before pushing back in.

River's eyes open widely as Jayne's body pushes in and out of her. Her nails scratch at his back as whimpers escape her throat. She feels full, filled up completely. She rubs her chest against his and tightens her legs around his hips, never wanting him to leave.

Jayne finds her mouth with his as his thrusts become sloppier. He knows he's not gonna last much longer so he reaches between them to find her clit. His mouth swallows her moans as he twists and pulls on the nubbin. His eyes cross as her walls tighten around him and he breaks the kiss so that he can hear her scream his name. He waits until she's writhing wildly under him before pushing deep inside her. He shouts her name as he cums and collapses on top of her after a few seconds.

River stretches underneath Jayne, her body completely relaxed. She feels completely safe with Jayne's body on top of hers.

Jayne rests his head beside River's head as he tries to come to grasps with what just happened. She's his now, completely his and there ain't a force in the verse that'll make him give her up. He groans when she stretches beneath him, feeling his body start to reharden. He rolls off her with another groan, pulling her body on top of his. "You okay?"

"Yes." River answers as she snuggles into his chest. "I like sex."

"So do I." Jayne agrees with a laugh.

River sits up and then crawls down his legs. She looks over her shoulder at him with a lusty grin. "I would like to try it this way now."

Jayne growls when River shakes her ass at him and quickly scampers down the bed to cover her back with his chest. His fingers dip between her thighs to find her still sopping wet. He spreads her folds and pushes deeply inside her.

River mewls and pushes her hips back against his. She arches her neck to the side as her fingers dig into Jayne's mattress.

Jayne buries his face into her neck and sucks harshly at the soft skin. His teeth clamp against her, holding her in place while his body slams into hers.

River's breaths come out in helpless pants as Jayne's body fills hers over and over again. Stars burst behind her closed eyelids when he bites her and she groans deep in her throat. Her body is floating with pleasure as he continues to push inside her.

Jayne finds her clit with one hand and pinches a nipple with other as he works in and out of her body. Her body bows and her arms collapse as her body milks his.

River falls face forward onto the pillow beneath her and uses it to muffle her release. Her ass still in the air, she spreads her legs further to accompany Jayne's erratic thrusts.

Jayne cums a few seconds after River and manages to flip them over so that he won't crush her. His hands fish on the floor until he finds the edge of her blanket and pulls it over them. "You alright?" Jayne mumbles into River's ear.

"I'm sleepy now." River replies as she turns to bury her face into his chest. "But I would like to have more sex when we wake up."

"Me too." Jayne agrees as he starts to fall asleep.

"Jayne." River says.

"Yeah baby." Jayne grunts sleepily.

"You are very big." River whispers. "But you fit inside me perfectly."

Jayne nuzzles the top of her head with his face. "Yep." Jayne agrees. "Perfect fit."
