Sidefic for Vurt Ninjas, set at some point after they've been playing Konoha for a while but before the Bad Things start happening in earnest.
A summary of Mainframe can be found
here (just scroll down; second to last), and while I had a specific game in mind for the pink Naruto and Sakura played, it's not important. A 'creamed' feather is a blue, black, or pink that had turned cream-colored after use; they're one-time only feathers, to keep the market up.
Warning: Not worksafe in general for the usual reasons and in specific for Naruto's knot. And if the last half of that sentence made no sense to you, you should probably not click on the cut at all. There's less potentially scarring lemons out there.
"Sakura!" Naruto said cheerfully upon opening the door. He immediately moved to fish something out of his jacket pocket, shouldering the door open the rest of the way as he did. "You're back early!"
". . . Yeah, this is my half-day," she replied with mild amusement, setting her soda can down on the table. "Like always. How'd the shipment go?"
"Great, great," he answered, waving the hand holding a packet absently and kicking the door shut. "I think. I finished up this morning and napped in office after that, but I didn't hear any yelling, so I figure things went smooth."
Sakura snorted and picked up the soda again.
"Where's Sasuke?" Naruto added, leaning to the side slightly as he moved toward the table and glancing down the hall at the bedroom door. "No way he's still sleeping."
"It's his turn to get the groceries," Sakura replied, nodding at the fridge. Naruto huffed, and then started undoing the flap.
Sakura drained the can while he pulled a pink feather out and tossed the packet on the table, but raised an eyebrow. Naruto noticed and turned to grin at her.
"Free sample of the new game!"
"Ooooh," she replied, pulling the can away and wiping a drop of soda off her lip with her thumb, before licking it off. Naruto's grin curled up a little, almost but not quite showing teeth.
"Got any plans for the afternoon?" he asked.
Sakura licked her bottom lip and leaned back against the counter, shifting her hips out slightly. "I think my schedule's free."
Naruto's grin slid into a smirk.
Sasuke still wasn't back by the time Naruto had gotten out of his brief shower--once Sakura learned that his idea of 'napped in the office' was 'curled up on the floor until Jiraiya stepped on me,' she insisted--and Sakura had spread one of the spare sheets out on the living room carpet.
Naruto liked having sex in the sunlight, and since Sasuke had thumb-tacked the thick curtains in the bedroom shut due to being the one who actually had to sleep during the day, it pretty much left the main room. Sakura wouldn't let him open the windows, but when the blinds were tilted up toward the ceiling and opened slightly, it came pretty close.
Sakura had shrugged out of her skirt and, since Sasuke would probably be coming through the front door sometime soon, traded her bra and shirt in for a loose translucent tanktop. Naruto just walked into the room naked.
Sakura rolled her eyes when he tossed the towel at one of the kitchen chairs, but only pressed the flat edge of the feather against her mouth. "Well . . . ?"
Naruto dropped onto the sheet with a grin, took the feather from her, and then touched the tip against her lips. Sakura parted them just enough for the feather to get through, and then slid her tongue slightly along the underside, keeping her eyes on Naruto's face as she did.
Naruto swallowed as he gently pushed the feather in, and for the moment Sakura was pretty sure she would never get tired of the way he looked at her like this.
Sakura caught his hand as he was pulling the feather out, tilted it around and pressed it against his lips. Naruto obediently opened his mouth to take it in; Sakura slid her fingers down along his and then pushed them against the back of his hand, before falling back onto the sheet. The marquee of the game was already starting to take over--she shifted, attempting to find a better spot on the carpet that prickled even under the sheet while she was still noticing physical stimulation, felt Naruto drape an arm over her stomach, and then she was in the game completely.
Naruto was there once the ads finished; Sakura barely glanced at him before she was preoccupied with gaping at their surroundings.
"What on earth," she asked.
Naruto slid an arm around her waist and began tugging her to the left. "This way, c'mon! You get the sweetest ride if you go in through here."
By the time the credits had ended and the lag left over from finishing the game had started to wear off, the sunlight had drifted a good foot across the ceiling. Sakura let her arms drop over her head, and stretched lazily; Naruto's arm slid down her stomach slightly when she arched her back.
"Weird," she declared.
Naruto was lying close enough that Sakura could feel the low rumble of his laugh, in a way that caused the muscles of her stomach to tighten briefly. He noticed the reaction, and slid his hand lower, until he reached the hem of her tanktop.
"Yeahhh, I think getting old's gettin' to him," Naruto agreed, tilting his head a little more to the side and watching her as he slid his hand underneath the shirt and up again. Sakura arched her back once more when it started to catch beneath her, shifting one of her legs up a little and bracing it against the carpet for support.
She chuckled. "It was still hot, though. I guess age doesn't change perversion."
Naruto snickered. "I could've told you that."
She laughed again, though her breath caught slightly when he pressed his thumb against her navel before sweeping it across and up. Naruto slid his hand along Sakura's stomach until her shirt was over her breasts, and then pushed himself up and above her, shifting so that he was straddling one of her legs, knee between her thighs.
Sakura spread her legs a little wider, giving him more room, and her stomach tightened in anticipation again even before Naruto kissed the skin below her navel. She let herself sink back against the carpet; the motion pulled her stomach away from Naruto's mouth, but he followed.
He nipped a little higher, making Sakura shift and bring her arms down slightly, and then kissed the spot just above her navel before dragging his lower teeth over her stomach, to the hollow between her breasts. She shivered at that, and a moment later pulled the leg he was straddling up, pressing Naruto's cock into the hollow of her hip. Naruto exhaled against her skin, and nipped the underside of her breast.
Sakura chuckled breathily again, and then pulled one of her arms down and worked it into the space between their bodies, brushing her knuckles against Naruto's abs as she reached down to hold his cock.
He'd come during the game--despite having worked weeks on it, which the part of his brain that was still paying attention to anything that wasn't Sakura noted as a sign that it was probably going to be a big seller--but luckily it had been early enough that he'd had time for the knot to go back down. He was starting to harden again, though; and when Sakura squeezed carefully over the area where the knot would form, he shuddered violently and had to restrain the urge to bite down, the need to just pull her legs up around his waist and fuck her now.
"Sakura!" he said hoarsely, reaching down and pulling her hand away. He held it against the sheet as he pushed himself up at little further and pressed his face against her neck; but after a moment, he slid his hand up so he was no longer gripping her wrist but instead had his palm against hers.
Sakura tilted her head to the side, deliberately baring her throat in a way that made Naruto growl against her, and then blinked. She stared for a moment before she thought to say, "Oh."
Naruto looked up when she shifted slightly towards the side, and noticed Sasuke lying near the edge of the sheet, wearing only a pair of sweatpants and curled away from them. "Finally got home."
"Did he take the pink too?" Sakura asked. She started to look to the opposite side, where the table was, but then gave up when Naruto's head blocked her way. "Wouldn't it--does it not cream?"
He laughed. "If someone invented a pink like that, they'd be assassinated for putting the industry out of business. Nah, he must've found the Mainframe I left in the package. . . ."
Naruto pushed himself up again and then crawled over her, shifting the hand holding her own from his right to his left as he did. Sakura dropped the leg she'd been rubbing against him to the floor when she figured out that he was moving, so he wouldn't trip, but made an unhappy noise at the loss of warmth. She curled onto her side as she watched him push Sasuke onto his back, tucking a forearm against her breasts and rubbing her shoulder slightly.
Sasuke grumbled when Naruto kept a hand pressed down on his collarbone, but his eyes were still closed.
"I never get what you like about those blacks," Naruto said, smirking down at him. "You break again?"
Sasuke opened his eyes and glared at him. Naruto's smirk pulled back to show teeth, and then he leaned down and kissed Sasuke hard.
Sakura looked away, though she kept her fingers tangled in Naruto's, and pulled her leg a little closer to her chest. She made a face when the motion forced her to notice how damp her panties were, however, and rolled onto her back again before hooking her free thumb under the side.
The squirming required to get the underwear off and tossed towards the other end of the sheet drew Naruto's attention again. He pushed away from Sasuke, licking the flecks of blood off his lip, and pressed a kiss to the sensitive skin in the crook of her elbow.
Sakura tried to ignore her reflexive shiver, and pouted at him.
"Sorry," Naruto replied, giving her an apologetic look that wasn't quite believable. He changed hands again, draping himself back over her, this time moving both of his legs between her own. "Just--making sure he was up."
Sakura rolled her eyes even as she spread her legs further, shifting around his hips, and then poked him in the calf with a foot. "Liar," she retorted. Naruto's reply was to run his palms over her breasts; Sakura hummed contentedly and pressed up against them, and then wrapped an arm around his neck and pulled him down into a kiss.
When he rocked his hips, though, sliding against her, Sakura shivered once before tilting her face away and moving to press a hand against Naruto's arm. "The condom. . . ."
Naruto whined in the back of his throat, but pushed himself up a couple seconds later. "I think I put one in my jeans . . ." he muttered in the strained voice of a man with an erection, looking over towards the kitchen.
Sakura considered making a face at him. ". . . You walked in here naked."
Naruto looked back down at her, with a 'you're kidding right please tell me you're kidding' stare, and Sakura went ahead and made that face.
"Damn," Naruto swore, dropping his head down to bury his face in her shoulder for another moment, before he pushed himself onto his knees and hands. "Okay, one second, dammit. . . ."
Sakura sighed dramatically, and folded her arms over her head before stretching out deliberately and rolling her eyes. Naruto recognized the move, both from previous nights and from the studio; it was the look of a woman who was saying 'I'm going to finish this up myself if you don't get a move on.' He knew that Sakura--unlike the actresses at the studio--wasn't serious about it, but it gave him the idea that turned into his next actions anyway.
Naruto shoved himself up enough to balance on his knees, and then caught Sakura's wrists and rocked back onto the balls of his feet, pulling her into a sitting position. He tugged her tanktop back down over her breasts while she was still giving him a confused look, and then gripped her waist and scooted them both around to face Sasuke.
Sasuke had sat up after Naruto pulled away from him, and was rubbing a thumb below the fresh cut in his lip gingerly. He blinked when he suddenly found himself with a lapful of Sakura.
"What--" Sasuke started to ask, and then cut off when Naruto grabbed his hands and set them over Sakura's breasts.
"Here," Naruto explained, ignoring the looks both Sasuke and Sakura were giving him, "she likes it when rub your fingers over her nipples. Gentle." He shoved himself up again, this time onto his feet, and jogged to the bathroom.
"H--!" Sakura began, and then broke off with a shiver when Sasuke shifted his hands. "Sasuke. . . ."
"Like this?" he asked, rubbing the sides of his thumbs over her breasts, a little awkwardly.
Sakura hesitated, and then placed her hands over his. She pulled them away slightly, then shifted them up and curled her pointer fingers over Sasuke's own, touching them to her nipples. He started to rub them up and down again, but paused and then followed him when she guided his fingers into a sideways motion, with mainly just the blunt nails skimming over the nubs. "Like that."
She felt Sasuke nod behind her, and swallowed. Sakura let her hands fall a few moments later.
Inside the bathroom, they heard Naruto swear and toss something against a wall. He stalked out and down the hall a second later, shoving the bedroom door open.
Sasuke gave a half-sigh, half-snort, and Sakura shivered again when the exhalation made her hair flutter. "I'm moving back to the couch."
"Okay." She scooted back when he started to. They didn't move far; the living room was small enough that the sheet bunched slightly against the bottom of the couch. When Sasuke leaned back against it, Sakura almost but not quite settled against his chest; and then she started when he splayed his legs out beside her own.
He was half-hard behind her; Sakura made a note to ask Naruto what kind of black Mainframe was, and bit the corner of her lip when Sasuke began skimming his fingers over her nipples again, hands in the same position she'd set them in before. "Nnnm. . . ."
She felt Sasuke's chin brush her head as he shifted it away from where her hair was tickling him. "Is the shirt. . . ?"
"It's okay," she replied, looking at his fingers again. "With the fabric, it feels . . . nice."
Sasuke nodded once more, and then shifted his chin again. Sakura felt a sudden jolt of embarrassment, to be staring at his hands on her breasts, when the sensation was doing something to her throat and stomach and cunt that only Naruto was supposed to be doing. . . . She looked up abruptly, and then reached up with one hand and started pulling her hair over her shoulder, out of his way. Sasuke made a vague 'thank you' noise.
"He planned this," he added, and his Adam's apple brushed Sakura's knuckles when he spoke. She chuckled and dropped her hand again.
In the bedroom, a drawer slammed shut, with a second one opening at almost the same time.
". . . Probably not this part," Sasuke amended, and this time Sakura laughed.
"Sasuke, why the fuck did you put your condoms where mine were?!" Naruto called down the hall.
"There was nothing in there when I put those in," Sasuke replied with mild annoyance, and Sakura yelped when one of his nails scraped too hard against her.
"Hey, hey, pay attention to Sakura!"
"You were the--ch," Sasuke cut off with a growl, and shifted so that he was using his middle fingers now instead of his pointer ones. Sakura leaned back fully against him this time, shifting her hips slightly as she did.
When she shifted them again, a few seconds later, Sasuke commented quietly, "He really . . . spends a lot of time on foreplay with you. Doesn't he?"
Sakura had been trying to decide if it would be worse to be embarrassed by fingering herself with Sasuke there or to keep waiting, so it took her a moment to process that he'd spoken, let alone what he'd said. "Uh? . . . Ah, yeah, I . . . with the knot. . . ."
"Ah," Sasuke agreed.
Sakura shifted her hips again, and then listened to Naruto slam another drawer shut, and decided that she could wait if she was distracted. "I was afraid to, for a while . . . when Ino and I looked up stuff on dogs, and I first read about that, I wouldn't. . . . I said we could have sex, you know, between the thighs, the first time." She brushed a hand over her thigh as she spoke, and then thought better of it when her hips twitched reflexively. She chuckled a little strainedly, to cover it in case he was looking. "I think that just scared me more, he really had to work hard, after, to . . . you know."
"You . . ." Sasuke sounded half-disbelieving. "You researched with Ino."
". . . ." Sakura could tell that some of the heat in her face was from embarrassment now, which is why her next words were defensive. "She dragged me into it, after I told her he was part dog. . . . I'd only dated pures before, so she said . . ." she added, trailing off, almost too quiet to be heard.
Behind her, Sasuke shook for a moment, and then laughed aloud.
His hands had stilled as he did, so Sakura couldn't even tell herself that the shiver that ran along her spine had anything to do with the physical and not the fact that she'd gotten Sasuke to laugh.
It didn't last long; he quieted after a few moments, and then went back to rubbing his fingertips over her nipples. Sakura didn't want to think about how much she missed the feeling of his chest shaking against her, so she shifted again and scooted a little further down the sheet. She stopped when she realized that new position placed Sasuke's still hardening cock against the small of her back.
"When," he started to say, after they'd heard Naruto yank open the closet door (now swearing pretty much continuously), but then stopped. Sakura noticed the hoarseness in his voice, and wondered if he was trying to distract himself, too. "I didn't know about the knot."
". . . ooh," Sakura murmured sympathetically. "That . . . well, if you were. . . ." She paused, and thought of something. ". . . Tell me you two weren't in a public place."
Sasuke snorted.
Sakura dropped her head briefly with a 'so cliché' noise. "He should have known better than to get into a tie somewhere like that. . . ."
"Mn," Sasuke replied, scraping his nails just a little harder over her nipples. Sakura had to agree that it was pretty weird to talk about their . . . their mutual boyfriend, or whatever Naruto ought to be called, and let the subject drop. She closed her eyes and leaned back against Sasuke's chest again, shifting her shoulders a little to find a more comfortable position, and swallowed when he changed back to using his pointer fingers again.
She wasn't sure when the noise from the bedroom stopped, but when she heard someone settle on the carpet a little distance away, she opened her eyes again and tilted her head down from where it had been resting against Sasuke's shoulder enough to see.
Naruto was kneeling on the corner of the sheet closest to the hallway, concentrating on pulling on a condom. Or more specifically, trying not to look at her and Sasuke long enough to get it on.
Sakura watched him for a moment, and then shifted her hips again when Sasuke's pattern faltered slightly. But when Naruto finished and fully looked up at them, the expression on his face gave her an idea that she followed impulsively before she could consider why or how it had developed.
Sakura lifted one of her legs and draped it over Sasuke's, and then laid one of her hands over his, causing him to stop completely. And then she arched her back and began sliding Sasuke's hand over the undercurve of her breast and down her stomach.
Naruto's eyes darkened a moment before he dropped onto his hands and began crawling towards them, growling low in his throat. Sakura's breath hitched at the same time as she felt Sasuke's cock jump.
When he was close enough, he grabbed Sakura's legs, hooking his hands underneath her knees before pulling her forward. Sakura yelped and quickly moved to steady herself, dragging Sasuke's hand to the floor in the process and letting go a moment later. The sheet rucked up behind her where Sasuke's weight wasn't holding it down.
Naruto continued tugging her forward until his knees were nearly wedged between her thighs; Sakura didn't have time to think about spreading her legs to make room before he slid his hands up them, cupping her ass and pushing her up. She wrapped her arms over his shoulders instead, and then shifted her legs as Naruto pulled her onto his lap, bending her knees and tucking them behind her until she was able to balance some of her weight on her feet.
It wasn't until after she felt the latex slide against her that Sakura realized just what it meant for Sasuke to be only an arm's stretch behind them. She started to turn her head, and just as suddenly was struck with an intense need not to see him, not to be reminded of his presence . . . they'd never, in the same room . . . one of them had always been out on an errand or left or gotten a shower when Naruto was with the other, but--
Sakura cut her thoughts off when she felt Naruto press a finger just slightly into her. She shifted her grip to his shoulders, steadying herself as she tried to push down.
Naruto made a hissing noise, other hand already guiding his cock to the right spot, and considered fingering her to an orgasm first--usually she'd come at least once before she let him inside, to make it less. . . .
But Sakura was his, dammit, not Sasuke's. His.
Naruto pulled his finger away and pressed upward carefully, feeling a moment later the give that told him it was the right place. He slid his hands up to Sakura's hips, digging his thumbs in slightly at he did, and then tugged her down.
Sakura made that soft noise she always did when he first slid in, her fingers tightening against his shoulders before she let go and wrapped her arms around his neck instead, burying her face in the crook between it and her elbow and breathing hard. Naruto slid his hands up until they were just below her shoulder blades, and then clenched the fabric of her shirt in his fists and concentrated hard on the always impossible need to stay still, to not just fuck and risk hurting her.
It took Sakura several seconds to stop panting harshly; when she lifted her head again, she found that Naruto had closed his eyes. She pulled one of her hands free and ran it down his back, thumb brushing his spine. Naruto shivered and tightened his grip on her shirt.
Sakura rubbed his back soothingly for a moment, and then pulled her hand up and set it against his shoulder again, doing the same with the other one. She had to make a slight adjustment before she was certain she wouldn't slip off, and then dug her toes into the carpet beneath the sheet and pushed herself up.
Naruto followed her, pressing his hips up in a needy, jerky movement, and under less tense circumstances Sakura would have smirked.
He never lasted for very long--it was a genetic thing, from being part dog; she had read it when she and Ino were researching. (Ino had immediately made a derogatory comment on the stamina rumor, which Sakura had been forced to both verify and disprove a couple weeks later.) He also was always careful, and gave her the lead; Sakura thought back to the way he'd shook under her hand, and pushed back down, trying to meet the awkward pace he was restraining.
It was a small power trip, really, to know that he willingly went against his instincts for her every time.
She'd only slid along his cock a few more times, clenching down when she'd pushed up with the last one, before Naruto pressed the side of his face against hers. "Sakura. . . ."
"Okay," she whispered, voice not much less hoarse than his. "Okay."
Naruto loosened the death grip he had on her shirt and brought his hands back to her hips, pulling her down and thrusting up at almost the same time.
Sakura closed her eyes, and let him move for her, trying to concentrate enough on keeping her balance to not wind up tipping them both over. Naruto was mumbling where his face was still against hers, half into her hair, but Sakura couldn't pick out more than a few words of it.
His fingers tightened painfully against her a moment before he shivered violently and Sakura felt the heat. She let her knees drop to the floor, trying to push as far down onto him as possible.
She felt the knot starting to swell soon after. Sakura bit her lip, and then folded her arms around his neck, pressing her forehead against them as she tried to repress her shivers.
Naruto's fingers loosened their grip a little while after the swelling had reached the point where it was almost too much, where it was almost too full, any more pressure or heat and she'd start crying and wouldn't be able to stop, and then Naruto would make that face like he had the first time, where he looked terrified and afraid that when she got free she was going to run out the door and never come back and. . . .
Naruto exhaled and slid his hands up to rub her back, pressing his face against the upper curve of her breast as he did. Sakura shuddered when the motion caused the knot to shift inside her.
"So pretty," Naruto murmured, rubbing her back in slow circles that weren't exactly even because his hands were still shaking, "so pretty, Sakura, thank you, you're always so pretty. . . ."
She had to laugh at that, and mumbled something about flattery. Naruto kissed the line of her collarbone, still murmuring in between.
He shifted again a few moments later; Sakura bit down on her lip, but released it a few moments later and said, "You should've thought this out better."
"Huh?"
"Your legs. Knees. Those."
She could feel Naruto make a face against her shoulder. ". . . Is this one of those trick things? Because you're not heavy."
"What," she replied as dryly as she could manage, and behind her Sasuke snorted faintly.
The sound reminded her that he was there, and had been there the whole time. Sakura shivered against Naruto and squeezed her eyes shut a little tighter.
"Hey, come--" Naruto started to say, and then, "--no, Sakura, is it okay if Sasuke's closer? If I can--lean on him or something, it'll be easier. . . ."
"I am not a wall," Sasuke replied, through the strain in his voice wasn't really conducive to sarcasm.
Sakura kept her eyes closed for several moments--long enough to feel Naruto start to shift again but then stop himself--before finally opening them. She leaned back just enough to see most of Naruto's face, and he splayed his hands against her back, as support.
"If you planned this, I'm punching you when I get loose," she informed him, and Naruto gave her a pouting but sheepish look.
"Meeeean, Sakura," he mumbled. She rolled her eyes and exhaled; and at that, Naruto looked over her shoulder again. She felt him pull one of his hands halfway away from her back, leaving the heel there while moving the fingers away, and closed her eyes once more.
The act didn't keep her from hearing Sasuke scoot towards them, however, nor did it keep her from feeling it when Naruto shifted again. When she tightened her arms around him reflexively, he made a soothing noise and ran his hands down her back to her hips, holding them firmly. "I've got you, Sakura, promise I've got you. Just wanna lean forward a little, okay?"
Sakura buried her face in the crook of her elbow again, torn between gratefulness at the attention and embarrassment at the way she was looking like some frightened little . . . girl in front of Sasuke. ". . . You don't have to coddle me," she muttered.
"Yes'm," Naruto replied, still good-humouredly, and Sakura jabbed him in the shoulder blade with a finger. He made a faint 'ow, not cool' whine, and then began leaning forward slightly, keeping his hold on her hips so that she wouldn't start to slide away and thus cause the knot to tug painfully against her opening.
Sakura tensed up more violently than anything of before when she felt Sasuke's chest against her back again. Naruto kissed the side of her neck and started rubbing small circles against her skin with the pads of his thumbs.
After she'd started to relax--just slightly, since there was no way to ignore Sasuke's closeness--Naruto pulled one of his hands away. The second followed a moment later in the opposite direction, his fingers skimming over her thigh and then down to find her clitoris.
Sakura pressed up against his finger reflexively, tensing her inner muscles and then shivering from both the sensation and the way Naruto made a hissing noise somewhere between satisfaction and pain. When he began rubbing in the pattern she liked best, clearly concentrating on getting it right despite the awkward position, she did it again deliberately; and this time the hiss was closer to satisfied.
Sakura jumped when she felt Sasuke suddenly grip her hips, which caused Naruto's hand to slip briefly; for a half a second she thought confusedly that the other man was trying to help steady her, and then Sasuke made a small, strangled groaning noise, and Sakura realized where Naruto's other hand had gone.
The knowledge made her dig her nails into Naruto's back when he began rubbing her clit again, and bury her face further into his shoulder, even though the air in the small space was too warm and muggy from her panting. When Sasuke made that same little noise again, Sakura rubbed her face against Naruto's throat until she'd gotten most of her hair out of the way, and then bit down.
"Fuck!" Naruto barked sharply, bucking his hips up instinctively and pressing her harder against Sasuke. Sakura made a high, startled noise, letting go, while Sasuke made low choking sound and tightened his grip on her hips--too hard, way too hard, but Sakura's pained cry was muffled against Naruto's neck--either to steady himself or as a result of something Naruto had done with his hand.
Sasuke suddenly leaned heavily against her a few seconds later, forehead resting more against her shoulder and the crook of her neck than on the strap of her tank top. His hands pressed down as he did, even though he couldn't push her much further down than she already was and wound up only causing the planes of Naruto's hipbones to dig harder into her thighs. Sakura didn't say anything, because she could feel how Sasuke was so tense that he was nearly trembling from it.
She did bite down again when Sasuke leaned a little more heavily against her; but this time Naruto wasn't caught as off-guard, though he still jolted.
Sasuke tensed up even more soon after, spine curving so that he wound up pulling away from her slightly; and Sakura dug her nails deeper into Naruto's back when she felt some of the semen splash against the lower curve of her ass. Naruto grunted.
A couple seconds later, he slid his other hand up until it was pressed against the small of her back, the first one rubbing her clitoris a little more certainly now that he only had one person to concentrate on. Sakura shivered at the still-wet feel of it, even though she'd heard him wipe it on the sheet, and then started shivering more violently and tightened her arms around Naruto's shoulders until she was pressed hard enough against him to feel certain that she had a grip on something even while everything was melting out of her grasp and control.
Sasuke released his bruising grip on her hips about half a minute later, muttering something when Sakura made a small relieved noise; it sounded a little like an aborted apology, but she couldn't make out words through the still-disseminating haze. He didn't move his forehead, though, and his harsh pants made the thin fabric of her tank top flutter slightly where it wasn't stuck to her skin.
Sakura was still for a few more moments, and then started to squirm; a little at first, and then hard enough that she made a pained noise when she pulled up too far.
"Whoa!" Naruto hissed, bringing his hips up after her and leaning them harder against Sasuke to keep from falling forward. He started rubbing his hand along her back, underneath the shirt. "Shit, Sakura-chan, Sakura, okay, be careful--"
"Too hot," she muttered, shifting again. "It's too hot, it's too hot!"
Naruto swallowed. "Okay," he soothed, bring his hand up further and pulling the shirt along with it, "lean back and I'll pull this off, okay? Please, Sakura-chan, don't freak, I don't wanna hurt you. I'll get it off and it won't be hot."
Her only response was to press her forehead harder against his shoulder. Naruto kept tugging her shirt up, until he had it up over her breasts and around her armpits; he had to gently nudge her before she loosened her arms and leaned back enough for him to be able to pull it up.
Sakura let the first arm she tugged free drop loosely down his back, but when he pulled the shirt off of the other one and tossed it to the side, she wrapped it around his neck and hid her face again. Naruto ran a hand down her side, firm enough not to be ticklish. "Better?"
Sakura shook her head, unable to find a way to explain to him that it was worse now, now that Sasuke's skin was touching her bare skin, after she'd had sex with Naruto--after they'd both had sex with Naruto, after. . . . "It's too hot. . . ."
Sasuke pulled away a few seconds later, and Sakura jerked at the sudden loss of weight before shivering reflexively at the cold air that took his place.
Naruto turned to stare at him, but Sasuke only crawled far enough to sit behind him. Sakura blinked and then closed her eyes again when the back of Sasuke's head and shoulders came into her sight over the top of her arm.
"Here," the other man said, to Naruto, "lean back. It'll be cooler for her, and you weren't helping your knees that other way."
Naruto hesitated, and then wrapped his arms around Sakura's waist before leaning back carefully.
Sasuke bent forward slightly at first, but then stiffened, and finally Naruto leaned back a little more heavily until he'd taken enough weight off his knees to endure it until the knot's swelling went down. "Thanks," he said quietly.
"Thank you," Sakura whispered, the words muffled against her arm and Naruto's shoulder.
Sasuke grunted, and rolled his shoulders in an attempt to find a more comfortable position between her arms.
By the time the swelling went down enough that Sakura could pull off of his cock with only a faint grunt, Naruto could tell from the way Sasuke's back kept shifting that he was smothering yawns.
Sasuke slumped forward after he heard Sakura sit down on the ground and felt Naruto lean away, rolling his shoulders loosely. Sakura rubbed at her hips for a few moments, and then gave up on everything and dropped over onto the sheet. The sharp twinge that the motion caused made her grimace briefly, but it didn't last long; she stretched her legs out a half a minute later, though she did so gingerly. Naruto glanced between her and Sasuke for a few more seconds before flopping onto the floor as well.
Sasuke stood up at that, tugging his pants back up around his waist. "I'm going to get a shower and nap before work," he said, starting to move towards the hall.
Naruto reached out and caught his ankle. Sasuke stopped, and turned his head slightly back towards them; and Naruto let go several moments later. Sasuke nodded once, before turning forward again and continuing towards the hall.
"Don't wake me unless the place is on fire," he added, before shutting the bathroom door.
Naruto shifted further onto his back, and stared up at the ceiling for a minute before looking over at Sakura. Her eyes were closed, but when he reached out to brush her hair away from her face, she dropped an arm over his chest and scooted closer.
Naruto stretched his arm up and then settled it around her back once she was curled up next to him. He started running his hand over her hip and side, almost absently, and Sakura settled her head on his shoulder.
"Are you okay?" he asked quietly.
"Nmm? Yeah," she replied, eyes still closed.
". . . What happened?" he finally continued, a little louder because Sasuke had turned on the shower.
Sakura was quiet for much longer this time before finally shaking her head; the motion caused some of her hair to get caught between Naruto's arm and chest. "Nothing. It's fine."
Naruto was tempted to ask if she really thought he would believe that, but several seconds later Sakura began faking sleep. He let his hand settle against her back and looked up at the ceiling again.
Sakura genuinely fell asleep a few minutes later, and when she woke up again, Sasuke had left for work and her guilt for not answering Naruto's question had alleviated enough that she didn't say anything. He never brought the topic up, either; so by the next day, Sakura assumed it was dropped.
The next night, however, the bruises on her hips from Sasuke's fingers had become visible, and Naruto pressed her against the back wall of the shower before kneeling in front of her and nipping each individual mark.
Sakura was tempted to laugh and ask why he was so jealous of another one of his bitches--but once she realized just how she had framed the question, she remained silent and ran a hand through his hair instead.
Sasuke and Sakura didn't speak to each other for the next few days, though as best as Naruto could tell neither of them were angry at each other. They were just . . . unnerved, or embarrassed, or . . . he wasn't sure, they wouldn't tell him. The silence might have lasted even longer, but Sakura had to ask Sasuke to where the car keys were when her turn to buy the groceries came up.
Naruto counted himself luckier than he had the right to be that they weren't mad at each other, and weren't particularly mad at him, and didn't try to get them to talk to each other sooner out of a fear of making everything go wrong.
After Sakura had returned with the groceries, she and Sasuke had a normal conversation over the new brand of coffee she'd bought when the store was out of their usual: Sasuke thought it was decent enough for the price; Sakura compared it to salty boiled grass and then went on to wonder just how someone could cause coffee beans to taste like grass, until Sasuke pointed out that it was it or tea. Naruto chimed in that this was a great time for both of them to get over their coffee addiction before they developed ulcers, which prompted Sasuke to give him an annoyed look and Sakura to roll her eyes and deliberately take another sip from her cup, even though she pulled a face again immediately after.
That night, Naruto had never been quite so aware of the fact that he was always the one who slept in the middle of the bed.
