Work Text:
Perched on the edge of the bed in his apartment above Onigiri Miya, Osamu sits obediently, blindfold on, in nothing but a small white towel around his lower half. Fresh out the shower, his dark wet hair clings to his skin as water droplets slide down his bare chest and arms. His heart thrums with a mixture of excitement and nerves as he anxiously waits for Rintaro to re-enter the bedroom from the bathroom down the hall. He waits – a little impatiently, until quiet, hesitant footsteps can be heard in the corridor outside his bedroom door.
Quiet as a mouse, Rintaro slinks inside and shuts the door behind him. Carrying his folded clothes, he discards them on top of the dresser and stands in front of Osamu. For a change, his gaze isn't on his high-school sweetheart, it's in the long, floor-length mirror to his right.
"How does it feel?" Osamu eventually asks from the bed, breaking the tense silence. "If ya don't like it— o-or it doesn't fit we can— oh. Fuck, do that again."
Tapping the end of the dildo against Osamu's cheek, Rintaro prods the hard silicone against his boyfriends slightly parted, spit-slick lips. Osamu's tongue greedily juts out to lick the tip, his cheeks flush bright red as he tastes it, saliva pooling in his mouth. Glancing at himself in the mirror, Rintaro runs his fingers along the shaft of the dildo, warming the lube in his hands on it. He gives it a few experimental jerks, admiring the realistic colour tones, matching his skin perfectly. If he squints, it almost looks as though it's his own, and not just attached to the harness strapped to his hips. A happy sigh escapes his lips as he admires himself, from his small tits and hardened nipples, to his slender, toned stomach and waist and to the dick that's about to fuck his boyfriend for the first time.
"Yer awful quiet—" Osamu nervously mumbles, feet tapping on the wooden floor as he chews his lower lip. "D'ya hate it? Not sure I can take it back to the store but I can find somethin' else. Maybe a different colour o-or is it too small? I didn't want anythin' too big considerin' it's goin' inside me and all." His nervous laugh is cut off by Rintaro's hand cupping his jaw, tilting his face up so he can kiss the middle of his forehead.
"Shhh, it's perfect. Watch–" Rintaro smirks as he speaks, slipping the head of the dildo between Osamu's parted lips. He chuckles darkly as Osamu greedily starts suckling on the end of it, sloppily kissing and spitting his saliva all over the tip. "We don't need to do that. This feels sort of...Powerful, actually," He says as he thrusts his hips towards Osamu's waiting mouth, choking and gagging him on his thick cock. "Oh fuck. Get it nice and wet 'Samu."
Osamu sits obediently and takes it. Relaxing his throat, he lets Rintaro fuck his face until tears start to stain the blindfold and he's coughing and fisting his hands in the bed sheets. Rintaro goes wild for it, feels his cunt throb and slick up as he watches his dick fuck in and out of his boyfriends mouth at a punishing pace. He watches Osamu drool all over himself, whimpering and sobbing as his own leaking cock tents beneath the towel. He unconsciously rocks his hips forward to chase the rough friction – like his dick is going to do anything other than sit there, hard, wet and useless.
When Rintaro finally pulls out from his mouth, allowing Osamu a moment to catch his breath, he thinks that if he could come out of it, he'd have made a mess out of Osamu's pretty flushed face already. God, Rintaro wants that. When he thrusts back into Osamu's mouth without warning, face-fucking him hard and fast, he wonders if they ought to buy a cum tube so he can make a real mess of Osamu.
"Fuck..." He pants, pulling out of Osamu's mouth when he gags, fat tears falling down his cheeks. "That was hot. Can't believe we've never done this before." He's only ever bottomed, and sure, getting fucked by Osamu's coke-can cock, feeling his heavy weight crushing Rintaro into the mattress and his thick thighs suffocating him, is fucking bliss. But switching roles, watching Osamu choke and beg for it, is something else entirely.
Rintaro slaps Osamu's thigh for good measure, grinning when he spies his boyfriend's cock twitch beneath the towel. There's a dark patch forming where his tip sits, and Rintaro can't help himself when he reaches out to pinch the end of Osamu's cock, smirking when he jerks and whimpers. They're taking it easy today, Rintaro doesn't want to push Osamu too hard for his first time, but they've discussed their kinks and there's a cock cage – among other treats, waiting in his shopping basket for next time.
"...Take it ya like it then?" Osamu finally says once he's caught his breath, gasping when Rintaro's fingers work their way up to press against his stomach and knead his chest.
"Best fucking gift ever," Rintaro laughs. "Get on the bed, big boy."
Scrambling up embarrassingly fast, Osamu abandons the towel and settles on his back. Legs up in the air, he shows off his hole, slick with lube and a little stretched from when he prepped himself in the shower. He feels exposed, especially with the blindfold, but all of that melts away when a cold, lubed-up finger prods at his entrance.
"You prepped yourself while I was at work."
"Y-yeah," Osamu hiccups. "Might have gotten carried away."
"Hot." A finger slides all the way in, zero resistance. "Did you come?"
"Kinda just...Edged myself a while." Rintaro makes a choked out sound at the thought, inserting a second and then a third finger.
"Without me?" He eggs Osamu on playfully, positioning himself between his boyfriends spread legs. Rintaro kinda wants to eat Osamu out, they both know he can come from a few fingers and a tongue lapping around his rim, but they'll go for a few more rounds before bed and he's been aching to get inside Osamu since forever. "Mhmm, you're tight now. Didn't even film it for me? How rude of you 'Samu."
"Shaddap," Osamu moans, his head tossed back into the pillows as his back arches up off the bed, Rintaro's fingers slowly starting to pump in and out of his hole. "Talkin' awful big fer someone who's goin' t'be beggin' to come on my cock in a few hours."
Rintaro can't even deny it, he usually prefers to bottom, crushed down into the bed by Osamu's weight as he's fucked from behind, face pushed down into the pillows until he's drooling all over them. Or when he's riding Osamu, slapping his fat tits until Osamu grabs him by the hips and fucks up into his cunt until Rintaro's sobbing and squirting all over him. Hot.
...However since buying the packer a few months ago, he's wanted to see what it's like to really fuck someone, have Osamu begging and crying beneath him to be hit deeper. Even though Rintaro's a little taller than him, there's just something about Osamu that makes him feel small when they're in bed together. His large, calloused hands, scarred from years in the kitchen, wrapping around his throat or spanking his ass. And now? The chance to turn Osamu into a garbling, fucked-out mess, is just too good to pass up. Rintaro feels a warmth blossom in his groin, slick drooling out between his thighs as he clenches around the silicone egg nestled inside him.
Once he's edged his boyfriend, fingers curling to tease Osamu's prostate until Osamu is breathless and panting, Rintaro can't wait any longer. He'd like to have Osamu beg a little longer for cock (his cock – the thought makes him feel all giddy and gooey inside), but he senses this won't be the first time he'll bottom, so Rintaro wastes no time in applying a little more lube to his dick. And then, he's lining up, prodding his cock against Osamu's stretched hole.
"Ready?"
Osamu eagerly nods and Rintaro slides inside. Fuuuuuuuuck.
"Get the remote," he commands as he bottoms out, closing his eyes and rocking his head back when Osamu flips the switch on the egg vibrator stuffed in Rintaro's cunt. "Ngh, feels good," Rintaro groans, tossing both of Osamu's legs onto his shoulders, kissing his ankle and grazing his teeth across his skin as he starts to thrust in and out. "Relax, that's it, fuck, you're a natural at this 'Samu."
"Rin, shit, y-yer cock."
"Yeah?" He teases Osamu, running a finger around his stretched pink rim before ghosting his fingers up to cup his balls, Osamu gasping and grinding his hips down to chase the sensation.
He fucks in shallowly at first, watching Osamu's hole swallow the head and the thick veins of his cock. A warm sense of euphoria washes over Rintaro, spurring him into fucking into Osamu's ass furiously. The vibrator pushes against his walls with each thrust against Osamu's hips and Rintaro moans out loud, sucking a possessive bruise into Osamu's calf, so overstimulated and drunk on the power he feels from fucking someone, he barely notices Osamu tense around him.
"Rin...Fuck...Rin," pants Osamu, his cock slapping wetly against his stomach. He's so well behaved that even when he's tipped to the very edge, he doesn't touch himself. "S'fuckin' good," he slurs, body trembling as he's slammed back and forth, scrambling to grab the headboard for purchase. "Blindfold," he says quickly, "wanna...See ya fuckin' me, please."
Rintaro almost forgot about it, and he leans over quickly without breaking his rhythm to remove it, smiling down at Osamu as he blinks his eyes open in the light.
"Hi."
"Hi."
"Feelin' good baby?"
"Fuck yeah," Rintaro says with a grin, slapping Osamu's thigh. "Teenage me would be so fuckin' stoked that we get to do this." Rintaro says it with a light laugh, like it's no big deal. It's hard to have a moment when there's a cock buried deep inside you and you're practically bent in half, but Osamu's heart flutters at Rintaro's words. His Rintaro's warm, rosy-red cheeks and barely-there smile make him push up at an awkward angle to kiss Rintaro on the lips.
"Love ya," he murmurs, nibbling Rintaro's lower lip and groaning when his boyfriend pushes his hips forward to shove his cock against Osamu's stimulated prostate until Osamu moans wantonly into his mouth, Rintaro swallowing it with a deep kiss. "Asshole. I ain't goin' to last if ya keep doin' that."
"Isn't that the point?" Rintaro chuckles, placing his palms flat on Osamu's broad chest to push him back down. "Don't touch your cock, come on this instead." Then, as he slides out from Osamu's hole, watching as it twitches and flutters around nothing, he adds a quick "Love you too." And sinks back home.
Rintaro is as close as Osamu, the vibrations inside his cunt making him clench and spasm as he fucks Osamu furiously, muttering praise against his skin as he peppers kisses and litters Osamu's legs with little round hickeys, his tongue lolling out so he can lick along Osamu's ankle.
"Rin, fuck, god, yer fuckin' cock, oh my god, It's goin' to kill me baby."
"Don't say that," Rintaro pants, groping and squeezing Osamu's hips. "Not done with you yet, wanna breed this cunt all night."
Rintaro's dirty talk doesn't take long to melt Osamu into a garbling, unintelligible mess of moans and pleas for more as his prostate is abused over and over again and then, after a particularly harsh thrust in, comes untouched all over himself. His cock kicks, and he sobs and writhes around the dildo penetrating him, shuddering through an orgasm as he paints his chest with ropes of come. Fucking him through it, Rintaro bends him in half so he can hit deepest, body and mind alight with the knowledge that he made Osamu come on his fucking cock. What the hell.
"Breedmebreedmebreedme," Osamu repeats, "fuck, Rin, so fuckin' full."
"God, 'Samu," Rintaro hisses, watching as his orgasm seems to keep going and going, his entire body convulsing, head tossed back into the pillows with his eyes squeezed shut. "Never thought you'd be such a slut for this. Need to take a picture." Osamu doesn't seem to hear, too busy sobbing from overstimulation as he's milked through the rest of his orgasm, toes curled and his cock leaking until it sits, spent, against his messy stomach.
Carefully, Rintaro eases out of him, collapsing between Osamu's spread thighs to lounge across him like a cat as they pant and catch their breaths.
"That was amazing," he comments after a long moment of silence, the vibrator still buzzing away inside him, making him flinch and stutter. Osamu perks at the distant buzzing, as though suddenly remembering Rintaro is yet to come, and without warning he's flipping his boyfriend onto his back and practically tearing the harness from his body.
Rintaro lays across the bed, allowing himself to be manhandled as Osamu plants his face between his sticky thighs, tongue snaking out to lap at his drenched pussy.
"Suck me off, 'Samu."
"Don't need t'ask me twice."
It takes all of thirty seconds before he's seeing stars, and another thirty seconds before he's flipped onto his stomach, Osamu rubbing his hard-again cock between his ass cheeks before returning the favour. When Osamu pulls out the egg, replacing it with his thick cock, Rintaro is pushed down onto the bed and thinks fuck yeah, this is where I belong.
...And they get a lot more use out of the strap in the weeks, months and years after that.
