Atsumu, without a shred, nay, an atom, nay, a sliver of an atom's doubt, was going to murder Komori. The last night at the All-Japan volleyball camp was supposed to be reserved for some volleyball, then a good meal and camaraderie. Not truth or dare. But this wasn't what got the red panda wannabe on Atsumu's shit list, no no, it was what happened during the game.

A few rounds went by, the game playing out as normally and awkwardly as could have been expected. Hoshiumi went along as aggressively as he could, Omi-kun tolerated the questions, even if he dodged most of the answers, and Tobio-kun did his best to play in earnest.

Atsumu did his damned to hide the way his gaze always fell on Tobio, to keep his blossoming feelings to himself. But he's always been a shit liar–ask his twin. So when the time came for Komori to pick Tobio's next dare, he had the utter gall to say, "I dare you to kiss the cutest guy here."

Here lies Miya Atsumu, dead and buried at the ripe age of 17. He lived a good life, playing volleyball and eating spicy tuna. He ascended to Heaven the moment Komori decided to ask Tobio to confirm the very last thing he wanted to know: who he likes. He could barely tolerate fangirls cheering while he served, how the hell was he gonna stand to watch Tobio kiss someone else right in front of him?!

Tobio immediately blushes, his eyes skittering to the gym floor. He chews on his lip before his head rises, his gaze meeting Atsumu's. Both boys stare at each other for an endless second, as if double, triple checking that they both had the right idea.

Shock floods Atsumu's chest, his eyes blown open in confusion. But Tobio doesn't move his head, his observant, focused eyes piercing through Atsumu.

"Ya think I'm cute?" manages to slip out of Atsumu's lips.

Tobio pouts a little, as if annoyed by the obvious question.

Atsumu's heart hammers wildly and as he stands, he makes a mental note to hug Komori before they all leave tomorrow. He walks across the circle and extends his hand to the younger setter. Atsumu smiles, "Come on, we're not doin' this here."

Tobio delicately takes his hand, his lips upturning just so at the corners.

Atsumu leads Tobio out the double doors, ignoring the surprised yells and gasps from the rest of the players. He would deal with them later, trust him.

He and Tobio find an empty hallway near the sleepaway dorms, the minutes of walking doing next to nothing to quell his racing heart–if anything, the fact that he's still holding Tobio's hand only made the excitable organ accelerate. Ignoring the almost heart attack, he turns to face Tobio. The younger setter never took his eyes away from him, his eyes big and beautiful, curious and reverent.

Atsumu didn't stand a chance. He slowly steps closer to Tobio, the boy backing up against the wall, and with his free hand, Atsumu runs his thumb on Tobio's cheek. "We don't have ta if ya don't wanna."

Tobio chirps, a little too excited. "I want to."

Atsumu can't ignore the rush of anticipation that fills his chest, his sudden fixation on Tobio's full, dry lips. If he waits a moment longer, he might talk himself out of it, so he doesn't; he leans in and kisses his cute little goody two shoes.

Tobio's lips are warm and gentle against his, and barely moving. For a second, Atsumu nearly forgets how to kiss, before coming back to himself and leaning into him, giving special attention to Tobio's bottom lip.

Tobio squirms under his lips, trying to mimic the movements that Atsumu does with considerable skill. Under Atsumu's delicate fingertips, his body feels warm and trembling, as if trying to contain his nervous excitement. Tobio does his best to brush his lips against Atsumu's, to gently bite, to match his coordination.

Atsumu's hand moves from Tobio's jaw to the back of his neck. It's clear to him that this is Tobio's first kiss, or at least his first real kiss. To his credit, Tobio is learning quite well. His hands cling to Atsumu, desperate for anything, everything Atsumu can give him.

They kiss until they're out of breath and have no choice but to stop. Atsumu steps back, forcing himself to give Tobio some space. He's dizzy and hot all over. Kissing his crush felt as amazing as he hoped it would have, even if he wants to whine that it's over.

He's not the only one. Tobio frowns as he comes back to himself, breathing erratically, his skin blotchy and red, his movements in his shirt and sweats screaming with agitation.

"Ya doin' ok?" Atsumu asks.

Tobio blinks and shakes his head, "I'm not sure."

"Tell me how ya feel," Atsumu orders, suddenly worried that he pushed the clearly inexperienced boy too far.

Tobio hums, "umm, I feel… warm? My heart is racing and my palms feel clammy. I don't know why, but I feel on edge? A little uncomfortable?"

Atsumu looks him up and down, and sure enough, he sees what he thought we would: a bulge in Tobio's sweats. To his credit, he holds back his smirk. "Tobio-kun, I think yer turned on."

"What?"

"Yer horny. Don't freak out, it can happen durin' a good kiss. Hm, I guess I'm a better kisser than I thought I was" he says, cocky.

Tobio doesn't budge, "I'm… horny?"

Atsumu frowns a little, "yeah? Haven't ya… felt this way before?"

"No."

"N– No?!" Atsumu gasps.

Tobio shrugs, "Not that I can remember."

"Uhh, wha– what about when ya get off? What do ya feel then?" Atsumu stammers.

Tobio blinks, "I don't 'get off' ever. I don't feel the need to." He states, with the appropriate air quotes to emphasize his point. "Is this how it's supposed to feel? Does it go away?"

Atsumu's mind races. Tobio's first kiss followed by his first experience of arousal. Now?! How on earth was he supposed to explain arousal and, god forbid, masturbation to a complete virgin?

Tobio squirms, his face tight with discomfort, "how can I make it stop? I don't like this feeling."

Atsumu clears his throat, "did ya learn in school about sex education and stuff like that?"

Tobio blinks, "oh, you mean orgasms?"

Atsumu nods, "that's one way ta get rid of yer feelin's. The other is ta wait it out, but that can hurt after a while. Did they… teach ya anythin' about how ta make yerself… get there?"

Tobio thinks back and shakes his head. "I don't think so."

Atsumu runs his fingers through his hair, anything to keep himself grounded. "Well, most guys jerk off ta get there. I think that's yer best bet since ya don't have any toys. Ya know how ta jerk off?"

Tobio frowns, "that's when guys rub their hands on it, right?"

Atsumu almost laughs in amusement, "yeah, ya know about that?"

"Not really, I've just heard other guys talking about it. But no one gives step-by-step instructions so I don't know how to do it."

"Maybe that's a good thing," Atsumu chimes in, "not every guy is the same. What works for someone else might not fer ya."

Tobio looks back at him, his frown disappearing. "What works for you?"

Atsumu sucks in a breath. "Me?"

Tobio nods, "how do you jerk yourself off?"

Atsumu's face pales. This is undoubtedly the most personal aspect of anyone's humanity and here Tobio is, just asking it outright.

He's adorable.

But as wildly inappropriate as the question is, he's asking out of need. If this is his first experience with arousal, it must be really strong and overwhelming. Atsumu remembers the first time he had that feeling–purely physical and needy. So so needy. He remembers taking himself in hand, not knowing what to do, just following what felt good until he finished. He needed a good nap after it, he hadn't expected it to be so all-encompassing. For it to happen to Tobio, after his first kiss nonetheless, means he must be feeling it all at once. It must hurt and Atsumu knows how good it'll feel on the other end.

Maybe he's giving in too easily. He couldn't care less. He takes Tobio's hand and nods toward the dorms, "I'll teach ya. Come with me."

Atsumu walks them to his room, hoping the game of truth or dare is still going on and they would have some privacy.

Why the hell are ya doin' this?!

Atsumu has no clue. He just knows that Tobio asked him for help and the selfish part of him, the part that thinks Tobio is really, really cute, is pouncing at the opportunity to see more. But he has to control himself, he would never forgive himself if he ruins Tobio's first everything. Despite his own hardness begging for Tobio's tiny mouth or skilled fingers, he has to behave.

Once in Atsumu's room, he sits on his bed's gray comforter, uncomfortable and unsure of himself. He isn't much of a teacher in the first place anyway, so how is he supposed to do this? He looks at Tobio, sitting at the foot of his bed; his focused eyes fixed on him, studying him, and the bulge in his sweats still present.

"How do ya… uh, how do ya want me to do this?"

Tobio cocks his head, "I don't know. I don't know anything about this."

Atsumu vaguely thinks about porn, but then remembers there's not much of a hands-on tutorial (heh). He scoots around, facing the other bed across the carpet. He would not be able to handle staring right at Tobio while he does this. "Do ya want me ta…tell ya what I'm doin'?"

Tobio nods, "in detail, if you can."

"What, ya gonna take notes?"

"Could I?"

"No!" Atsumu yelps.

Tobio blinks at him, his brows furrowing together before releasing. "I'll watch then."

Atsumu takes a deep, shaky breath and steadies his hands on his sides. "Alright, Tobio-kun, I hope yer payin' attention."

He closes his eyes and lets his head loll back, allowing his mind to sink, sink into his usual fantasies. His body relaxes, even as his usual fantasies don't work on him as they usually would. He can't remember the last time he felt this tense–it wasn't even that he was pent up, he came the night before coming to camp, but he was acutely aware of his audience.

Tobio, sitting on his knees, his delicate fingers resting on his comforter, his expression intrigued; his skin soft and pink in its blush, his lips full and pursed. It's all Atsumu can do to keep his eyes fixed on the bed opposite him that Hoshiumi would sleep in later. His skin tightens with every breath, every ounce of his blood funneling into his dick. The wonder of their kiss was nice, of course, but this?!

Atsumu clears his throat, remembering his lesson. "I… I start by thinkin' about what I want. Um, who would be doin' this with me. Where we'd be, what I'd be doin' to them. Stuff like that… ta get me ready."

"What are you thinking about right now?"

You.

Atsumu steadies his breath, "nothin' right now. Sometimes I think about porn I like watchin' or I make it up on my own," he ends there, hoping Tobio wouldn't pry.

He allows his hands to explore his body, denying himself his needy dick, "then I, I touch my body. Just ta tease or ta get ready fer it."

Out of the corner of his eye, he sees Tobio copying him, his fingers idly traveling across his stomach and thighs, his legs parting just so under the caress. Atsumu bites his tongue to hold back his reaction. Tobio would be the death of him, he knows it.

His fingers travel up his thighs to reach his cock, now fully hard and waiting, "when I–mm–touch myself, I start with a light touch. I don't wanna start jerkin' it at top speed, ya need ta work up to it." He takes himself in hand, gingerly dusting his fingertips over his dick, even the little amount of pressure helps take the edge off. "If it's been a while and I'm pent up, it'll feel more shockin' or even painful. Start slow and work yerself up to where it feels good."

He sees Tobio nod, the boy's fingers brushing against his own length, eliciting a soft gasp, his eyelids dancing and fluttering.

"Relax yer grip," Atsumu says, "it's a lot fer ya, ya need ta take it slower."

Tobio nods, his fingers releasing slightly. "Okay, I'm… I'm slowing down."

"Good," Atsumu breathes. "Once ya get used ta it, ya can start movin' yer hand. Ya can see what type of stroke ya like before ya go into yer pants. Some guys like short 'n quick, others long 'n slow."

"And you?" Tobio asks, his fingers closing around his hard cock, gently tugging up and down the shaft. His lips fall open but his eyes never leave Atsumu.

"I like it all, havin' any type of hand on my dick, it's enough. It's–it's what I need." Atsumu moans, his voice cracking at the edges. The torturous slow pace, the lasting tease, it's not enough, not nearly enough. His fingers snake under his shorts, his dick throbbing under the little stimulation. "Once—mm—once I'm comfortable, ready, I hold myself tighter. I… I like workin' myself up until I have some pre at the tip," he says, rubbing his fingers against the wet head.

Tobio mutters, for once averting his eyes.

Atsumu gives him a look, coaxing him to meet his gaze, "yeah? Feel good?"

Tobio nods, his skin blotchy and beautiful. "Can I see you?" He asks, his voice soft with hope.

Atsumu whips it out in a second. He pushes his shorts and underwear down to his ankles and slips one foot out, turning towards Tobio, letting him see it all.

Tobio's eyes grow at the sight of Atsumu's pretty dick, his balls neat and heavy under the thick, deeply red shaft. His tongue darts out, automatically, as if longing for a taste. Then, he seems to remember himself and raises his hips to shimmy out of his sweats, letting himself bob out.

Atsumu shouldn't stare. He shouldn't. He absolutely does. Tobio's cock is, somehow, cute, adorable, and as pretty as he is; it's slender and long, his head pink and shining, his thighs quivering under his nerves. "Tobio-kun," he says in a voice much deeper than it was a few minutes ago, "I'll get ya there. Follow along," he takes himself in hand again, going right into long, even strokes.

Tobio does, observing and matching his pace, never once taking his eyes away from Atsumu's ministrations. His brows join together once or twice, the sudden onslaught of pleasure taking him by surprise. His breathing turns heavy, the slightest, smallest moan under his breath when his fingers brush his head.

"I like makin' myself desperate," Atsumu explains, a much better grasp on his voice now as he proudly shows himself off, "I like waitin' until–aa~– I can't hold on anymore, 'til it feels like I'm about to come all over my sheets and… and I try to hang on just a little bit longer," he says, his voice breaking at the edges.

Tobio gasps, his hand keeping at the torturously slow pace that must be driving him insane, "I, oh, I don't think I can last that long, I, I don't think I could stop if I tried," his hips pick up, sliding into his fist on instinct.

Atsumu's lip quirks up, his signature lazy grin coming in at full force for the sight before him, presented just for him. How does it feel to be the luckiest guy in the world? Well, Atsumu would say it feels almost perfect. "Yer first times will always be a lot, once ya learn ta control yerself, ya can start experimentin' with what ya like, different types of strokes or toys, stuff like that. Ya can find yer favorite spots on yer body, I think they're called erogenous or somethin' like that"

"Why does your body have to play a role," Tobio grunts, restraining a gasp as his shining fingertips slide against the head, "does it actually do anything?"

Atsumu allows his hand to move just a touch faster on his cock, his other hand going down to fondle his balls–he figures Tobio should learn sooner, rather than later, about them. "Sex is a full-body thing, Tobio-kun, try with me."

Tobio nods without taking his eyes away from Atsumu's hands, his focused gaze never straying. His other hand follows in the movement, pressing gently on his balls, playing around with them. Tobio's hips move with the sudden touch, unaccustomed and at once, unprepared for how much he would enjoy it. The delicate pads of his fingers, gently pushing, stretching, pressing into the soft, wrinkled skin.

"Yeah? Ya like that?"

Tobio hums as his head lolls back, his chest rising and falling in time with his hand. "Yes, yes I… I do."

"Keep watchin'" Atsumu orders, his hand rising on his body and making sure Tobio's does as well. His gentle fingers caress up the midline of his abs, dancing there for just a moment, even though it does nothing for him. Tobio follows, his gaze unyielding even as his hand undergoes the movement just the same. Atsumu keeps going, leading Tobio up to his chest, internally betting this might be his sweet spot.

And if it isn't, well, it sure is Atsumu's–at least one of them gets to enjoy it.

His fingertips circle his nipple, the hardening nub pronounced on his chest, just how he likes it. If Tobio hears his sharp intake of breath, he doesn't show it in his reactions. He does, however, show his own.

Tobio's lips tremble at the touch of his fingertips, "ohh, I do like that," he whimpers, his voice jumping an octave.

"I do too, I really do," Atsumu struggles, "the thought of someone else, touchin' me, everywhe–."

"Atsumu-san, cou– could you come closer?"

Atsumu doesn't bother holding back his grin. He scoots closer until he's right in front of Tobio, close enough to touch, close enough to taste. "This close enough fer ya?" He breathes. "Ya want me ta touch ya?"

Tobio shakes his head, "not yet, I don't think, aaa, I can handle that. But, could you, um…"

"Anythin', Tobio-kun, anythin'," Atsumu promises, his hand betraying him and gripping himself more tightly, "what do ya want from me?"

"Kiss me until I come, please," Tobio begs.

Who is Atsumu to deny him? He abandons his chest and grabs the younger setter by the nape of the neck, holding him steady as he falls into him, all the pretense from their earlier kiss gone.

Tobio kisses back with energy, desperation, need. His tongue weaves into Atsumu's mouth naturally, and Atsumu returns the gesture, weaving into Tobio's tongue with his own. Their eyes meet, heady blushes on their cheeks, eyes only cracked open under the onslaught of pleasure.

He's kept Tobio waiting long enough.

His fingers tighten on the back of his neck as he pulls away from the kiss, breathing onto his lips as he speaks, "do ya wanna come or not?"

"GOD, yes, please, please," Tobio begs, his lips swollen and pink. His hand took off on its own, working himself up past any possible return.

Atsumu kisses the bow of his lips as he directs, "when I kiss ya, ya collect all the pre at yer head and touch yerself as fast as ya can. It's gonna feel intense, just let it happen. I'm right here with ya, I got ya, alright?" He groans, his tone husky with need.

Tobio nods, his hair rubbing against Atsumu's forehead and nose. He's too endearing fer his own good. Maybe he can find a way to love it, as if he doesn't already. He leans in, stealing Tobio's lips with an urgency in his hips. Aside from Tobio, he's kept himself waiting a while–his cock is needy and painfully hard, every stroke feels just on the cusp of being too much.

Under his lips, Tobio kisses as best as he can, his hands taking over–one racing on his pretty pink cock and the other holding onto Atsumu's arm for dear life, his fingertips pressing into him. How good must it feel? To get off for the first time while being kissed? Atsumu wishes he could feel the same way Tobio felt.

His fingertips close on his skull, tugging at his hair and exposing his slender neck. Tobio lurches, surprised, as Atsumu kisses up and down his neck, leading with his needy tongue. He ghosts, "faster" against Tobio's skin and grins when he groans from the effort, "yer not gonna last, look at ya, yer breathtakin'," he says, mostly to himself.

"I am?" Tobio groans out, his voice tight and about to break. His hand stutters, as if just barely reaching the edge.

Atsumu kisses his chin before biting his lower lip, "my goodie two shoes."

Tobio gasps–Atsumu choosing this moment to claim his mouth with his tongue once more–as he comes all over Atsumu. His hand stuttering, his broken cries into Atsumu's mouth, his fingertips trembling on his chest as his beautifully pink cock shoots so much white on Atsumu's abdomen.

Atsumu tightens his hold on Tobio's nape, holding him steady as he fists himself for the rest of it; Tobio's hips follow a path of their own, slamming furiously into his fist, as if needing to give it all to Atsumu. Atsumu licks up every moan, every whimper that Tobio entrusts to him until he shudders, painfully.

"Careful, yer gonna be–aah– sensitive after ya finish," Atsumu groans, his cock begging for a release.

Tobio slumps, slightly, "yeah, I can feel it…" he lets himself go, his pretty pink cock shrinking back just a tad, "are you almos–"

"Mhm," Atsumu moans, hanging on by a millimeter.

"Would you come faster if I touched your chest?" Tobio asked, straightening up.

Atsumu gives an incoherent whimper that Tobio correctly understood as 'YES!' Tobio gets his fingertips under Atsumu's shirt and gives a cursory flick on his nipple while claiming his lips once more.

"Tobio-kun, yer, yer perfect, Atsumu whines as he finally comes, Tobio's fingers circling his nipples all the while, feeling so better than his own ever have. He stains the comforter as his body writhes through the release, his skin screaming with heated pleasure under Tobio's gentle touch. The kiss is messy and wonderful, it keeps him grounded while his brain short-circuits.

He slumps in his shoulders as the high dies down, his forehead knocking against Tobio's own, the lazy grin on his face taking on a more goofy shade. He feels so damn happy here. Atsumu's cock gives one last drop before stinging to the touch, his body ripe and red with effort and a damn good orgasm.

Tobio, his eyes focused, yet much more relaxed than they were a while ago, remain on him, "you're a good teacher," he teases.

Atsumu snorts, "shut yer trap! There's much more ta teach, if ya wanna learn…"

"I do, but first, make me," Tobio presses, his lips pulling into a beautiful smile that Atsumu wouldn't mind making part of his daily routine.

"Oh, I plan ta" Atsumu says, pulling his cute little crush onto him.
