Chapter Text
“You know how…” Sasuke said, then he trailed off, his fingers slowing where they drew loose swirls through Kakashi’s light gray chest hair. His eyelids were drooping, his body felt deliciously heavy and warm, and he didn’t want to move from this spot, like, ever.
“How what, Sasuke?” Kakashi asked languidly, slowly dragging his fingertips up and down Sasuke’s upper arm, probably the only thing keeping Sasuke awake.
“Hmm?” Sasuke asked muzzily. “Oh.” He yawned extravagantly, then smoothed down Kakashi’s chest hair. “You know how you won’t fuck me before I turn eighteen?”
“...Yeah,” Kakashi said, almost a question.
“Well, I had an idea,” Sasuke said, then, “Sorry,” after letting out another long, jaw-creaking yawn.
“Go on,” Kakashi said, his voice guarded.
“It’s just an idea, don’t worry,” Sasuke was quick to reassure him. “I just thought… what if I fucked you?”
Kakashi’s stroking hand stopped tracing its light lines up and down Sasuke’s arm. He was silent for a few seconds.
“Well?” Sasuke asked, snuggling up closer to him and trying not to tense up. “Is that a good silence or a bad silence?”
Kakashi turned his head to kiss Sasuke’s forehead. “It’s a… thinking silence. Give me a minute.”
This time as they cuddled, Sasuke's heart was racing and his palms were clammy, and sleep was the farthest thing from his mind. He had no idea how long passed, though it seemed like an eternity, before Kakashi spoke up again.
“If we did this, would you stop pushing for me to fuck you?” he asked.
“I mean, yeah. I think that would scratch the itch just fine. If we did this, I would happily wait until I was eighteen for you to return the favor.”
“You’re sure?” Kakashi asked, tilting Sasuke’s face up to make eye contact. His gray eyes were searching, the perennially bloodshot left eye making the stare even more intense.
“I’m sure, Kakashi,” Sasuke said with a smile. “That’s part of why I suggested it.”
Some of the intensity left Kakashi’s gaze. “What’s the other part?”
Sasuke hesitated, suddenly shy. “I… think it could be really hot, having you like that. I mean, if I can do it right. But if we do this, it’s not going to be just once, is it?”
Kakashi sighed, and Sasuke hoped that meant he was giving in. “No.”
“Then I’d have plenty of chances to learn what I’m doing. You could teach me,” Sasuke said, and he watched Kakashi’s face soften. His hope heightened until it was a near-surety. “So, what do you think?”
Kakashi’s mouth slowly curved into a grin. “You already know what I think, don’t you?”
“I was hoping so.” Sasuke grinned back and let his hand slide down Kakashi’s chest to his hard stomach.
Kakashi laughed lightly. “Are you already ready? Ah, to be seventeen again.”
“What, can’t keep up, old man?” Sasuke teased, his hand slipping under the blanket to wrap around Kakashi’s soft cock. Which wasn’t a surprise—they’d only just finished getting each other off spectacularly, and it was rare that Kakashi was ready to go again within the first hour.
Sasuke could feel himself stirring though, getting hard quickly now that he could imagine, without worry that he’d get shot down, being between Kakashi’s legs, buried inside his hot body.
What kinds of noises would Kakashi make when Sasuke fucked him? Sasuke already knew that while Kakashi wasn’t a screamer by any means, he wasn’t silent either, and he wondered if he’d sound different when he was getting fucked than, say, when he was having his dick sucked.
God, Sasuke was ready to find out.
“What do you say, Kakashi?” Sasuke asked, curling his hips forward just enough to let his rapidly hardening cock brush along Kakashi’s hip on the way up. “You wanna give it a try? I wanna see what you feel like.”
Kakashi’s cheeks were a gorgeous pink, and his arm came around Sasuke and hugged him tight while he kissed his forehead again. Sasuke closed his eyes and smiled, loving the sweet gesture as he held the man’s most sensitive part loosely in his hand, feeling the thick softness of it, stroking it gently to feel the silkiness of the skin.
“Let’s give it a try,” Kakashi said against his forehead.
Grinning, Sasuke carefully let go of his cock and drew away from him slowly, then reached for the bedside table drawer and fished out the bottle of lube. He had the sudden mental image of his lubed-up fingers slipping into Kakashi’s body, and he moaned softly.
“Don’t get too far ahead of me, now,” Kakashi said dryly.
Sasuke turned half-lidded eyes to him. “Sorry,” he said. “I’ve been thinking about this for weeks.”
“Come on, then,” Kakashi said, turning the blanket back to expose his long, bare body, and Sasuke’s cock gave a hard twitch. His mouth went dry. He watched the muscles in Kakashi’s thighs and side move as he kicked the blanket off the bed, and he was overcome with lust for this man, who was about to let Sasuke fuck him.
Working some moisture up in his mouth, Sasuke crawled over to Kakashi and pressed their mouths together, then Mmh’ed when Kakashi caught the back of his head and took the kiss deeper. Soon enough, though, Kakashi let him go, and Sasuke climbed between Kakashi’s spread thighs.
Sasuke took a few seconds to devour him with his eyes, his big, soft cock, his heavy balls, his long, thick thighs, the perfect swells of his ass where they were joined, and his tiny, pink asshole.
How had he never looked at it before? Oh, he was sure he’d seen it, when he’d crawled between Kakashi’s legs to suck him off, but he’d never really looked.
It was adorable. Sasuke smiled, looking down at it, and began to understand, a little at least, why Kakashi seemed so obsessed with Sasuke’s. Oh, he’d said, at first, that he wasn’t going to finger Sasuke too often, but it seemed as though Kakashi found reasons to slide his fingers into Sasuke’s body at any opportunity… and to rub his dick against it half the time he did that.
“What is it?” Kakashi asked, giving Sasuke a crooked half-smile.
“Nothing, just… I’ve never really looked at it before. It’s… cute.” Sasuke gave him a smile back.
Kakashi laughed softly. “Thanks. Well? Are you just going to look at it?”
“Impatient,” Sasuke teased, clicking his tongue, and Kakashi laughed again, the sound dropping into a lower register. Sasuke felt his dick throb between his legs. What was he waiting for?
He slowly slicked up his fingers and dropped the lube, brought his fingertips to Kakashi’s asshole. He brushed against it, watching Kakashi’s face intently, then pressed the tip of his middle finger against the little divot. “You ready?” Sasuke asked, his voice coming out husky.
“Yeah,” Kakashi whispered, tucking a hand behind his head and watching Sasuke right back.
Mouth slowly dropping open, Sasuke slid his fingertip inside Kakashi, feeling the hot squeeze of his body around Sasuke’s finger. “God,” he whispered when his finger was nearly buried, and Kakashi took it so effortlessly, his body welcoming the penetration.
Withdrawing his finger slowly, heart banging in his chest, Sasuke asked, “You’ve done this before, right?”
“Plenty of times,” Kakashi said lazily, and Sasuke felt the hot flush of jealousy rise to his cheeks.
Sasuke slipped two fingers into Kakashi now, not giving him a chance to adjust to the penetration before he slid them deep. He took it so easy. But his cheeks were flushed with arousal, his mouth parted, breath coming out a little faster now. Good.
“Are you usually the one who gets fucked?” Sasuke asked, jealousy making him uncareful as he thrust his fingers in and out.
Kakashi groaned. “I switch, really,” he said. “But I do tend to bottom more, yes.” Then he moaned softly, a sound Sasuke rarely heard from him, and Sasuke relented.
I’m here. They’re not.
It helped, as it usually did, when he remembered to remind himself. He slowed his fingers and leaned down to kiss Kakashi’s soft cock. “Sorry,” he said quietly. “I just…”
“I know,” Kakashi said warmly. He reached down to brush his fingers through Sasuke’s hair in the front, then dragged his touch gently down Sasuke’s cheek. “But you’re—”
“I know,” Sasuke said, tossing him a smile. “I’m here. They’re not.”
“That’s right,” Kakashi said, smiling softly back. “And I want you more than I’ve ever wanted anyone.”
That helped put some wind back into Sasuke’s sails, and he felt his dick, which had softened up just a little, begin to perk up again.
“You’re gonna get me, too,” Sasuke said, taking in Kakashi's long, leanly-muscled body, his thick, soft dick… his asshole, shiny pink and gripping Sasuke’s fingers. Kakashi’s lips parted, eyelids sliding down a little, and Sasuke withdrew his fingers. He was getting ready to lube up three fingers when Kakashi murmured, “You don’t have to do that. I’m ready.”
“Oh,” Sasuke said with a slow throb of arousal, then he poured out a small palmful of lube and spread it along his dick, fully hard again and dripping wet. He supposed he was glad he’d had that uncomfortable jealous interlude—now he was probably not at risk of blowing his load as soon as he was inside Kakashi.
Well, not at so much risk. His hand itself already felt dangerously good twisting slickly up and down his cock.
To give himself a bit of a buffer, he leaned forward and kissed Kakashi’s cock again, then licked from his heavy balls to his sheathed tip. He kissed the tip through the foreskin, then brought his clean hand up and held Kakashi’s dick while he took it into his mouth. Soft like this, he could fit the whole thing, no need for deepthroating. It felt so good like this too, so different, soft and pliant and almost rubbery, but as usual still warm and tasting like the very essence of Kakashi. He sucked it a few times before he heard Kakashi moan quietly.
“Feels good,” Kakashi whispered. “It’s not the same, but… it feels really good.”
“Mmh,” Sasuke moaned, starting to get into it. He twisted his head, letting his lips move along the circumference of Kakashi’s thick dick.
“Oh,” Kakashi groaned, his cock plumping up in Sasuke’s mouth, and Sasuke’s cock gave a hard jerk at the feeling. Sasuke bobbed his head a handful of times, feeling it lengthen and thicken deliciously in his mouth, until he couldn’t fit the whole thing anymore.
“Sasuke, fuck me,” Kakashi said in a thick voice. Sasuke’s cock absolutely ached. He let Kakashi slip out of his mouth, then he drew up onto his knees between Kakashi’s spread thighs.
“Tell me if…” Sasuke trailed off, momentarily overcome by self-doubt. Kakashi was so experienced—who knew how many times he’d done this before, with partners who knew what they were doing, who were bigger than Sasuke, who knew how to make him feel good—
“I will,” Kakashi said, his face pink, eyes glittering behind his hooded eyelids. Sasuke had done that to him, Sasuke had made him hard so much sooner than he’d usually be, Sasuke…
Was here. Because Kakashi wanted him here. Because Kakashi wanted him here very much, in fact. And Kakashi wanted him to fuck him.
Sasuke took a deep breath and dropped down lower on his knees, thumbed his hard cock down so that it was aimed at Kakashi’s slick asshole. He ran his hand down Kakashi’s lightly heaving belly, brushing his thumb over his nearly-fully-hard shaft.
“You’re so fucking hot,” Sasuke breathed, skimming his hand along Kakashi’s spread inner thigh.
Kakashi gave him a pink-faced grin, then said softly, “I love you.”
Sasuke couldn’t help but smile back. “I love you, too,” he said. Then he circled Kakashi’s wet hole with his tip, biting his lip, and began to ease in.
God, Kakashi was so hot inside, and tight, his inner walls all slippery with lube, and Sasuke had to close his eyes as he sank in deeper and deeper, Kakashi’s ass seeming to pull him in. Sasuke hitched his hips back and thrust in deeper, and his eyes flew open when Kakashi moaned, deep and low and all desperation. He was watching Sasuke through hooded eyes, dark with pupil, his lips wet. He licked his lower lip as Sasuke watched, and that punched a hard grunt out of Sasuke.
He wanted more. He flattened his hands on Kakashi’s inner thighs and fucked in deeper, fucked into that molten slickness, Jesus Christ, and let his hands slide inward until they bracketed Kakashi’s heavy balls.
“Kakashi,” he moaned, and threw his head back with a soft cry when Kakashi’s asshole tightened around him. He kept fucking though, kept going deeper until his short, dark pubes bumped against the bottom of Kakashi’s balls. “You feel so good,” Sasuke whispered.
“You too, baby,” Kakashi breathed, watching Sasuke closely, as if memorizing him, as he began stroking Kakashi’s balls with his thumbs. They were wrinkled-up and tight against the base of his cock, which was full and thick and long, and if Sasuke could have managed to get it in his mouth just then, he would have in a second. Hell, he was tempted to pull out and go down on him, make Kakashi come before they really started going—that might take some of the pressure off Sasuke’s shoulders.
But… he wanted to know what Kakashi felt like from the inside when he came. The very thought made him moan—and then he realized he’d slowed to almost a standstill.
If he wanted to fuck an orgasm out of Kakashi, he’d have to actually fuck him. So he started thrusting deep, deep, biting down hard on his lower lip every time he buried himself fully in Kakashi’s perfect body.
Panting, he dragged his hands upward to spread over Kakashi’s clenching abs, then, finally, he wrapped a hand around Kakashi’s big cock. He peeled back the foreskin and groaned when precum pattered down onto his hard belly.
“Your whole body,” Sasuke panted, “is such a fucking turn-on. You have no idea.”
Kakashi moaned Sasuke’s name, his eyes finally closing in what Sasuke hoped was arousal, hoped was overstimulation, but the good kind, the kind that made your toes curl and your legs shake. Sasuke snapped his hips harder, stabbing into Kakashi now as he jerked him off slowly, getting Kakashi’s precum all over his hand, and god. Kakashi had only gotten wet a couple of times, when he was really turned on, and it had never been like this. Sasuke twisted his hand on the way up and more cloudy droplets of the stuff dripped out to decorate his stomach, and Sasuke shoved in and ground his hips, and the way Kakashi gripped his pillow and moaned loudly made Sasuke’s cock-head tingle alarmingly.
“Kakashi,” Sasuke said breathlessly, “stop being so… sexy.”
Out of breath and hoarse, Kakashi laughed softly. “Tell me what you want me to do,” he whispered.
“Ahhh,” Sasuke moaned. “I want you to fucking… come on my cock.”
And he could see the arousal pass over Kakashi’s face, could see it in the goosebumps that flashed over his chest and hardened his nipples.
“Tell me what you like,” Sasuke whispered, and their bodies crashed together over and over as he kept on fucking Kakashi deep.
“You’re doing perfect,” Kakashi breathed, then he rocked his hips, the movement of the sleek muscles in his torso mesmerizing and arousing, and Sasuke whimpered at what that did to the feel of him wrapped around his cock. Panting, Kakashi stared down at him. “Maybe… a little harder.”
Sasuke immediately dug his toes into the mattress and rammed harder into Kakashi, panting loudly. He hadn’t been prepared for how much exertion this required—sweat beaded up on his forehead and dripped down his chest, and Kakashi’s thigh, where he gripped him with one hand, was also slick with sweat. It felt like they’d turned the thermostat up to a hundred.
“Kakashi—” Sasuke groaned, closing his eyes and smearing a new pulse of precum down Kakashi’s thick cock. He fucked him hard and deep, making helpless noises of pleasure, and Kakashi started making them, too, high, lost sounds that Sasuke had never heard him make.
“Oh god,” Kakashi moaned, and he turned his face to the side, pressed his forehead against his raised bicep, and seemed to seize up around Sasuke. “Sasuke!”
“Fuck,” Sasuke spat, and he watched Kakashi’s dick jerk in his hand, watched Kakashi’s mouth drop open in a long, loud moan, watched strands of pearly come shoot out and get all over his flexing stomach and chest. His body twisted and strained, and his insides seemed to try to wring out Sasuke’s cock.
Then it was over, and Kakashi panted hard, sucking in huge lungfuls of air. He softened up around Sasuke’s cock, and Sasuke slowed to a stop inside him, letting him come down a little. He was close, though, trembling with it, his dick twitching and jerking inside Kakashi’s ass.
Looking for some compromise between letting Kakashi come down, and fucking Kakashi until Sasuke came deep inside him—and god, even thinking that made his dick jerk—Sasuke leaned forward and pressed out his tongue, licked up a long strand of jizz from just above Kakashi’s softening dick up into the fine fuzz of his chest hair. Kakashi’s sweat and come together were delicious, and the feel of his chest hair tickling Sasuke’s tongue made Sasuke’s hips shove forward.
“Are you waiting on me?” Kakashi asked lazily, stroking a hand through Sasuke’s sweaty hair. “You don’t have to. I want to feel you come, too.”
“Mmh,” Sasuke moaned, pressing his forehead against Kakashi’s upper chest, sweat dripping down his nose and onto Kakashi’s skin.
“Fuck me,” Kakashi whispered, and Sasuke groaned and dug his knees in, rocked in deep. He moaned as he kissed Kakashi’s chest, then he raised his head to look at Kakashi’s face, maybe an inch too far away to kiss.
“God, I wanna kiss you,” Sasuke breathed, grinding in hard. Kakashi moaned. He cupped the back of Sasuke’s head and leaned down as Sasuke dug his knees in and stretched up, and their mouths met with a hot jolt. It felt electric, that kiss, felt as if it ran all the way down Sasuke’s spine, and he groaned loudly into Kakashi’s mouth.
“Mmmh,” Kakashi moaned softly, rolling his hips again, one hand flattening between Sasuke’s shoulder blades and skimming down his sweaty back. Sasuke broke the kiss to pant, broke the kiss to fuck faster, and Kakashi’s hand on his lower back urged him on in a quick rhythm.
Sasuke stared into Kakashi’s pink, sweat-stippled face, and Kakashi stared right back, his whole body being rocked by Sasuke’s thrusts.
“Come inside me,” Kakashi breathed, and Jesus, Sasuke knew what that did to Kakashi sometimes, but he’d never thought it would be aimed at him. His cock-head tingled, his balls drew up tight, and his hips moved even faster, fucking Kakashi so hard the mattress springs squealed loudly under them.
“Oh god,” Sasuke cried out, then he dropped his head against Kakashi’s chest.
“Come on,” Kakashi said quietly, voice strained. “Give it to me.”
“Oh god, oh fuck!” Sasuke moaned, and his hips stuttered as the first hard pulse shot out of him. He cried out loudly and wrapped his hands around the backs of Kakashi’s shoulders and thrust, pumping himself out into Kakashi, thrust, spilling himself out deep, thrust, thrust, until his orgasm finally wrung him dry. Eventually his hips slowed to a stop and he panted against Kakashi’s skin, wet with both of their sweat.
“Fuck,” he whispered. He raised his head to look at Kakashi, who looked fucked-out and relaxed and happy, and Sasuke felt a hard smile tugging up the corners of his lips.
“You, Sasuke, are a natural,” Kakashi said, tucking a sweaty hank of hair behind Sasuke’s ear.
“A natural at fucking,” Sasuke said, in a better mood than he could remember being in a long time—and he’d been with Kakashi for the better part of a year, so that was saying something. “I bet that’ll look great on a resume.”
Kakashi barked a surprised laugh. He grabbed Sasuke by the sides of his face, leaned down close and kissed him hard. Sasuke pushed up, groaning a little when he slipped wetly out of Kakashi’s body, and wrapped an arm around Kakashi’s neck so that he could properly kiss back.
“Sasuke,” Kakashi said softly when they pulled apart.
“Yeah?” Sasuke asked, rubbing their damp cheeks together.
“Nothing,” Kakashi said, voice still soft. “I just wanted to say your name.”
Sasuke smiled. “You know what? I wanna make you say it again. And again, and again, and again, until you’re sick of me fucking you.”
“Never gonna happen,” Kakashi said with a smile in his voice.
Sasuke pulled back to look at him, and found Kakashi watching him with a calm, tender smile on his face that sent a wave of warmth washing over him.
“I foresee your name being called a lot in the near future,” Kakashi said, his smile widening.
Sasuke leaned down to kiss him and felt Kakashi’s soft, heavy cock pressing into his belly. He felt himself twitch thicker at the feel of it, at the memory of Kakashi breathing, Come inside me, and he groaned. Could he? Already?
If there was ever a time it was possible, it was tonight. “Kakashi,” he said in a low voice. “What if I want you to call my name again right now?” He rolled his hips, his thickening cock rubbing against the crease between Kakashi’s hip and thigh.
“Oh, really?" Kakashi asked, pink blooming in his cheeks. “Ah, to be seventeen again.”
“What, can’t keep up, old man?” Sasuke asked, and Kakashi laughed.
Then, “Sasuke. Fuck me,” he said, looking Sasuke in the eyes.
“Yeah,” Sasuke agreed, already breathless. “Yeah.”
—the end
