It all started innocently, really. Well, more like curiously.
They’re two teenage boys going through puberty who happen to be horny — which is perfectly normal for men their ages. So, really, what’s a little porn watching between best friends? Atsumu would say this is normal. Rintarou doesn’t seem to think otherwise either.
One minute they were casually talking about their sexualities ; Atsumu mentioning how he thinks he’s bisexual because sometimes he likes watching porn with women and sometimes with men, and Rintarou humming nonchalantly, saying that he’s pretty sure he likes men but also he doesn’t really care.
And then, Atsumu frankly doesn’t even remember which one of them suggested the idea first, the next minute they were grabbing his laptop so as to search for porn to watch. Rintarou is his best friend, they don’t have any secrets between each other. They can totally watch porn together without making it weird.
At least that’s what Atsumu thought.
Because now they’re only two minutes in, and Atsumu is struggling. Since both of them mentioned liking men, they opted for gay porn. And fuck. Usually Atsumu doesn’t have any issue focusing on the videos he chooses to watch. Right now he does, though.
He’s trying his damn hardest to focus on the video in front of him but all he can think about is Rintarou’s warm thigh pressed against his own. They had to sit like this so that they could place the laptop on their thighs between them. And Atsumu’s ears, instead of being focused on the moans coming from his laptop, are for some reason intensely focused on the way his best friend’s breathing is becoming more and more irregular by the second.
Atsumu doesn’t even dare turning his head to check Rintarou’s face because he’s scared of what he could see. He does, however, pick a pillow from his bed and place it on top of his crotch. He hopes he isn’t being too obvious with the gesture but, to be honest, he couldn’t care less either way. He can feel himself getting harder, to the point that he can’t hide it just with his sweatpants, and the last thing he wants is to make Rintarou uncomfortable.
“Are you hard?” Rintarou asks bluntly. Because of course he does.
Atsumu shrieks and unconsciously presses the pillow more strongly against himself. He immediately curses under his breath as the shot of pleasure the friction gives him just makes him grow harder.
“Maybe,” he breathes out, forcing himself to keep his eyes on the laptop’s screen.
He doesn’t see him, but he can feel Rintarou’s eyes on his face. Atsumu blushes under such an intense gaze and prepares himself for the incessant teasing he knows his best friend is about to give him. It’s not the first time and it definitely won’t be the last. Sometimes, Atsumu wonders how much blackmail material Rintarou has on him, but then he forces himself not to think of it.
This time, however, nothing comes out of Rintarou’s mouth. Then, “Me too,” Rintarou says simply after several seconds of silence.
Atsumu turns his head so fast that for a second he’s afraid of getting whiplash. His eyes immediately go to Rintarou’s crotch and, indeed, he can clearly see the outline of his best friend’s hard dick through his sweatpants too. Atsumu’s eyes widen in surprise and he can’t help keep looking. Apart from his own, he’s never seen a hard dick in real life before. Well, Rintarou is still wearing clothes of course, but still. He gulps as his stomach does some weird somersaults.
He doesn’t know for how long he stayed like this but at one point Rintarou clears his throat. Atsumu almost jolts out of the bed and Rintarou has to quickly grab the laptop so that it doesn’t crash on the floor.
“Why are you like this?” Rintarou asks, no real heat in his voice as he puts the laptop on the floor at the foot of the bed. “It’s normal to get hard while watching porn,” he rolls his eyes.
Right. Rintarou can’t know that Atsumu isn’t hard because of the porn video but because of him. That would definitely make everything weird.
“Right,” Atsumu voices his thought. “I just never watched porn with someone next ta me.”
Rintarou hums. He seems to be deep in thoughts for a few moments before he reopens his mouth and proceeds to throw Atsumu’s world completely off its axis. “Do you wanna jerk off?”
Atsumu blinks once. Twice. Thrice. “What?”
Rintarou, honest-to-god, simply shrugs. “I mean, we’re both hard. So unless you wanna wait it out, we could just get rid of the hard-ons.”
Atsumu blinks again and he shakes his head for good measure. “Ya serious?”
“Yeah,” Rintarou shrugs again. But then there’s something akin to uncertainty that crosses his face and a small blush appears on his cheeks. “We don’t have to, though, Tsumu. I can just use your bathroom. Sorry if I made you uncomfortable.” Rintarou hurries and offers him a smile that looks off before he starts getting up from the bed.
Atsumu almost throws his pillow out of the bed and jumps forward to grab Rintarou’s arm before he even registers he’s doing it. “Wait,” he screams dramatically. “We um, I mean, we can.”
Rintarou turns his head to him and raises an eyebrow. “You don’t look or sound so sure. Don’t force yourself for me, Tsumu. Really, it’s fine.”
“No I– I’m not forcin’ myself. I’m curious actually.” He mumbles the end of his sentence quietly but Rintarou doesn’t miss it and his eyes widen in pleasant surprise.
When Atsumu raises his head, Rintarou is smirking. “You’re curious uh?”
Atsumu groans and feels himself blushing. But before he can take his statement back, Rintarou gets rid of both his sweatpants and boxers in one go. Atsumu very graciously chokes on his saliva and his head spins, feeling hotter than ever.
What the fuck.
Rintarou’s dick springs free, hitting his stomach and standing proudly between them. Atsumu’s eyes are fixated on it and he unconsciously licks his lips. Fuck. Why is Rintarou’s dick pretty? Dicks shouldn’t be pretty.
“Your turn, Mr Curious.”
Atsumu huffs but gets rid of his own clothes just as fast. In the excitement, he even gets rid of his shirt and only realizes he’s fully naked when he hears Rintarou chuckling at his eagerness. He blushes profusely and, because he apparently also got rid of his brain-to-mouth filter, says the first that gets to said brain. “Ha, mine’s bigger.”
Rintarou stares at him completely unimpressed.
Atsumu winces a bit but flashes him a grin anyway. He should have expected that. Rintarou really doesn’t have anything to be self-conscious about. Yes, Atsumu is bigger, but Rintarou’s dick is definitely longer. Not by too much but it has Atsumu gulping anyway.
Have dicks ever been pretty? Atsumu doesn’t think so. Yet, Rintarou’s dick is pretty. He thinks his thoughts are repeating themselves but he can’t really register anything. He wants to touch Rintarou’s dick.
Atsumu sits back down on the mattress and Rintarou does the same. He doesn’t know what to say. Rintarou looks at him teasingly, a certain glint in his eyes and Atsumu prepares himself for a comment. Except it doesn’t come. Rintarou shakes his head lightly and shrugs.
“Do you want to continue watching porn while you jerk off?” Rintarou asks, referring to the laptop that they put away a few moments ago.
“Erm,” Atsumu starts and stops himself. Is it an appropriate thing to say that the view of a naked Rintarou on his bed is ten times hotter than any porn video they could put on? He’s fairly sure it’s not. “I’m good,” is what he chooses to say.
Rintarou eyes him so intensely that Atsumu feels like his best friend is seeing right through his soul. Atsumu gulps. Rintarou hums.
Then, Atsumu blurts, “Can I jerk ya off?”
Rintarou’s eyes shoot up all the way to this hairline and Atsumu quickly brings a hand to his mouth as his face feels like it just caught fire.
Rintarou recovers first. “Oh?” He smirks. “You wanna touch my dick?”
“I’m sorry! I- um. I dunno what-”
Rintarou chuckles through Atsumu’s rambling and it effectively shuts him up. “I’m okay with that,” Rintarou says. If Atsumu wasn’t too focused on his own internal fight, he would have noticed the way Rintarou’s cheeks reddened.
Atsumu blinks. “What?”
“You can touch me, if you want. Can I touch you?”
“Erm. Ye- Yeah. Fuck. Yeah. Ya can.”
Rintarou chuckles again but he doesn’t address Atsumu’s obvious clumsiness. Instead, he simply nods and slowly moves his body so that he’s closer to Atsumu.
Atsumu definitely lets out a small yelp as he watches his —very naked, very hot, and very hard— best friend approaching him. Rintarou smirks at his reaction but once again, he’s nice enough to not mention it.
Rintarou settles comfortably next to him. Both men have their backs against the wall, sitting across the bed’s width. Atsumu recalls that the position is similar to the one they had just before when they were watching the video. Except that Rintarou’s thigh that was pressed against his own was clothed and now it’s utterly naked. Oh God.
“Do you have lube?” Rintarou breaks the silence.
Atsumu chokes on air. “I- Ye- Yeah? Why?” He chuckles awkwardly.
Rintarou raises an amused eyebrow at him. “Erm, unless you want me to spit on your dick, I’d need something to ease the glide.”
Unless you want me to spit on your dick.
Atsumu’s face burns as the statement keeps repeating itself over and over in his mind.
“Oh?” Rintarou’s voice sounds again, tone even more teasing. “You’re into that?”
“No!” Atsumu sputters, and his face feels even hotter. “I have lube!” He announces, way too loudly for the close proximity they find themselves in, before he quickly retrieves a bottle from his nightstand.
Rintarou laughs next to him and Atsumu is surprised to note the way his heartbeat quickens at the sound. He puts it down to embarrassment and the wish to kill his best friend and doesn’t let himself think about it.
Atsumu hands the lube to Rintarou and watches, completely transfixed, as the other man applies the liquid on his fingers. Atsumu has always been fascinated by Rintarou’s hands — not that he’d ever admit it aloud. His dick twitches at the thought that he’ll have this same hand on himself in a few moments.
“Give me your hand,” Rintarou says. Atsumu obeys without even thinking and he blushes when Rintarou hums in pleasant surprise.
Atsumu watches Rintarou pouring lube on his hand and he unconsciously licks his lips. If Rintarou notices the gesture, he doesn’t say anything. When he’s done, Rintarou puts the bottle of lube on the mattress and focuses on warming the liquid up between his fingers.
Atsumu doesn’t move. He’s frozen in place as he’s completely enthralled by the vision of Rintarou right now. He looks like he knows what he’s doing and Atsumu has no idea how that’s possible. From where he stands, they were supposed to be both awkward virgins.
Rintarou snorts and laughs and it’s only then that Atsumu realizes that he’s voiced his thoughts. He blushes furiously and avoids Rintarou’s knowing gaze. “I don’t need to have fucked to know the basis of sex,” Rintarou deadpans, although there isn’t any real heat behind his words.
“Right,” Atsumu mutters. He doesn’t know if he feels better or not after that, but at least he has the confirmation that they’re on the same side.
Then there’s suddenly a warm, wet hand that grabs his dick and Atsumu jumps out of his skin, letting out the most high pitched cry he’s ever let out. His face burns and he doesn’t even dare looking at Rintarou’s face, knowing damn well that his best friend must have the biggest smug smirk on his face ever.
Not knowing what to do yet not wanting to be left out, Atsumu does the same and goes to wrap his hand around Rintarou’s dick in turn. Atsumu swallows back a moan at the touch. He’s touched his own dick plenty of times but somehow this feels different.
Rintarou jolts too and hisses instantly. “Shit. Tsumu, your hand’s cold as fuck!”
Atsumu’s eyes widen and he immediately retrieves it. He got so lost in thoughts earlier that he didn’t warm the lube up. Rintarou doesn’t let him go away, though. With his hand that isn’t around Atsumu’s dick, Rintarou grabs Atsumu’s lubed hand and places it back on himself.
Atsumu’s eyes widen slightly but he does what he’s asked and properly wraps his fingers around Rintarou. He bites his bottom lip and starts slow glides so as to apply the lube along the entire length. Rintarou lets out small hums so Atsumu continues, smiling to himself.
A few seconds later, Rintarou starts doing the same and Atsumu has to force himself not to moan out loud. Just like touching another dick doesn’t feel the same as touching his own, being touched by a hand that isn’t his own doesn’t feel the same either. It feels strange. Not negatively, but it’s like Rintarou’s hand somehow amplifies everything.
It doesn’t take them long before they start properly jerking each other off and soon enough, they’re both rendered uncaring of the sounds they let out. Atsumu gave up on biting on his bottom lip to muffle his moans and Rintarou is the same, his mouth staying open as small pants occasionally slip out freely.
Atsumu doesn’t dare watch him for too long, though. Because then he gets the inexplicable urge to kiss him. And he doesn’t know how to explain that. In fact, he doesn’t have any explanation for himself. He feels confused most of all.
His body is experiencing a lot of new, strange, and confusing feelings today. Ever since he and Rintarou started whatever this is, ever since the start of the porn watching. Atsumu thought it would just be a fun afternoon with his best friend and that the day after they’d go back to before, as if nothing happened at all. But right now he’s not sure if he’ll be able to do just that.
How could he go back to normal now that he knows what Rintarou’s dick looks like? How could he go back to normal now that he knows how it feels to wrap his hand around said dick? How could he go back to normal now that he knows how Rintarou’s hand feels around his dick?
Fuck. He’s so screwed.
“I have an idea,” Rintarou says after a moment, after their arms uncomfortably bump into each other one too many times.
“Mh?”
Before he has the time to ask what this idea is, the hand around his dick disappears and Rintarou moves away from him. Atsumu will forever deny the whine-like sound he let out at that. Rintarou chuckles at the sound, seemingly taking this as Atsumu’s eagerness and wish to cum. And that’s more than fine to Atsumu, definitely better than deciphering whatever the fuck Atsumu actually feels.
“Lay down,” Rintarou tells him.
Atsumu frowns in confusion but does as he’s told. He moves from the wall and lays down properly on the bed as if he was sleeping.
Rintarou hums appreciatively and before Atsumu can ask him why he made him change positions, Rintarou comes back on the bed and straddles him.
Atsumu chokes on his saliva, feeling his face burn yet again. “R- Rin? Wha-”
“It’ll be easier this way. Trust me, it’ll feel good.” That’s the only explanation Rintarou gives him before the man grabs both Atsumu’s and his own dick and starts jerking them off together.
Atsumu lets out a deep, almost animalistic groan before he shuts his eyes and bites his lip harshly, hoping that the pain of it will stop him from cumming instantly. There’s a bunch of lightning patterns that he can see behind his eyelids, it feels like he’s seeing stars. In fact, he isn’t sure he’s not.
Atsumu unconsciously brings his hands to Rintarou’s thighs and buries his nails in the flesh when the other man quickens his pace around both their lengths. Rintarou moans at the action and Atsumu does the same in turn.
The sensation of both their dicks gliding together in Rintarou’s large hand feels otherworldly. It’s nothing Atsumu has ever felt before, he can almost feel his head spinning.
Rintarou lets out another, louder moan when he tightens his grip and Atsumu groans. His eyes flash open and oh— he wasn’t ready for the sight he’s met with.
Rintarou’s face is flushed, his hair is disheveled, his mouth is open and his eyes are hooded and dark. He looks like the personification of sin and lust. Atsumu gulps once, twice, and thrice.
“Rin,” he whimpers. He doesn’t know what he wants to say, doesn’t know if he was planning on saying anything at all, but he feels the need to call for the other man’s name anyway.
Rintarou whines softly at the call of his name and Atsumu groans, burying his nails even deeper in the man’s thighs. The vision of Rintarou above him is absolutely glorious, Atsumu can barely contain his orgasm anymore.
“I’m close, Tsumu. I- Nghh.”
Atsumu groans and nods profusely. “Me too, Rin. Me too.”
Rintarou nods several times in turn and quickens his pace even more. They both let out twin moans when Rintarou presses on their tips by accident and, when Rintarou tightens his grip ever so slightly around them both one last time, they’re done for.
Atsumu chokes on his saliva and groans loudly before he feels his whole body spasm as he comes. Rintarou follows him after just a few additional strokes. He moans so sweetly above him that it has Atsumu’s dick spurt a few additional drops of cum.
Atsumu has never come that much in his life. His stomach is a mess, Rintarou’s cum spurted all the way up to his pierced nipples and he definitely doesn’t miss the way Rintarou eyes them hungrily.
Both men stay like this for a few moments, coming down from their highs and trying to catch their breaths. Rintarou looks absolutely ethereal in his post-orgasm glow and Atsumu feels something almost possessive at the sight of it. Suddenly, Atsumu is eternally grateful for the fact that he’s the first one to ever see Rintarou like this, and he feels the urge to keep it that way.
He didn’t realize he started caressing Rintarou’s hips gently until the other man smiled softly at him. Atsumu gulps. Oh. He doesn’t know if he’s ever seen such a smile from Rintarou being directed at him.
The two men lock eyes and, after a few seconds of silent conversation, Rintarou leans in at the same time as Atsumu raises his head. Their lips meet in the middle in a kiss that’s way too soft in comparison to what they just did, but Atsumu wouldn’t have it any other way. They quickly get lost in it and moan in each other’s mouth when their tongues touch for the first time.
Atsumu’s hand settles on Rintarou’s waist and he doesn’t miss the way the other man shivers. Atsumu smiles and squeezes, because he can, and because he’s still feeling completely out of it. He can barely believe what just happened.
They part after some time when Atsumu starts feeling gross about the dry cum on his chest. Rintarou gets off of him and cleans his torso with wipes he found in Atsumu’s nightstand and they put their boxers back on when they’re clean enough. After that, the two men go downstairs to have their afternoon snack and end up watching a movie in the living room.
Atsumu thinks that maybe they should feel weird around each other. Or that at least they should maybe talk about it. But he doesn’t feel either of those things. In fact, he feels as comfortable around Rintarou as he’s always done, and he thinks that’s what matters the most.
