Chapter Text
Shouyou’s world consists of his friends at school, the stray dog he pets every morning on the way to school, and Samu nii-chan and Tsumu nii-chan.
His Mam always works until late at night, except on Sundays (that’s the day Shouyou doesn’t have school! Which is nice), because Papa isn’t here anymore. Shouyou doesn’t know why. But every time he asks, Mama always twists her mouth, like every time Shouyou cries on Sundays and she gets up and leaves Shouyou alone until Shouyou doesn’t cry anymore. So Shouyou learns quickly that it’s better not to ask. Mam usually just sleeps a lot on Sundays though.
But Shouyou is fine. Every day after school, Samu-nii and Tsumu-nii come to his house to play with him. And on Sundays, when Mam is asleep and he’s hungry, he just walks down the narrow street beside his home, to Nii-chans’ house. It takes him five-times-twenty steps. Of course Shouyou can count until twenty. But he can’t do multiplication with twenty yet—his multiplication table stops at ten. Though he can only perfectly remember up to eight.
Samu nii-chan and Tsumu nii-chan are twins, but Shouyou can different-iate them just fine. Samu nii-chan cooks for Shouyou and Tsumu-nii every evening, because their parents own a restaurant in the shopping centre and will only come back at 10, sometimes midnight. Samu-nii always cooks good food, Shouyou likes Samu nii-chan.
But if Shouyou is honest, he likes Tsumu nii-chan waaaaay better.
Tsumu-nii always gives Shouyou candies before dinner when Shouyou wants some (Samu nii-chan must never know or he’ll be angry at them both), and he always agrees to play with Shouyou. He also has a lot of games Shouyou doesn’t know about, teaching Shouyou these new games whenever he’s bored of playing the PlayStation or ball games. Like this one game where Shouyou has to look the opposite way of where Tsumu-nii’s hand is pointing. If Shouyou loses, he’ll get tickled as punishment. Tsumu nii-chan loves tickling Shouyou’s sides with his hands, or Shouyou’s ears with his lips. Shouyou always ends up crying from laughing and all tired, but it’s so fun. Tsumu nii-chan’s rubbing feels nice. Whenever Tsumu-nii loses, Shouyou tickles Tsumu-nii between his legs, because Tsumu nii-chan is the most ticklish there, apparently, a secret he told Shouyou after the first time they played this game. Tsumu nii-chan always ends up all red and sweaty and panting, because he likes to hold his laughs down, he said. Shouyou wins this game a lot. He’s really good at it.
Whenever Shouyou tickles that area of Tsumu nii-chan, he always finds it hard as a rock. Tsumu’s uniform pants or sweatpants look really tight there. Which is weird, because Shouyou’s is always soft. That’s where his peepee is. Shouyou thinks perhaps that’s what happens to your peepee when you’re as adult as sixteen like the twins. He never asks Samu-nii, because it’s a secret between him and Tsumu nii-chan, and he’s afraid to break his promise with Tsumu-nii. What if Tsumu-nii hates Shouyou for it? He wouldn’t have a friend to play with anymore, and he’ll have no one who kisses him good night. Tsumu-nii’s good night kisses always feel good, making him all sleepy, though his lips always end up wet. This is also a secret between him and Tsumu-nii.
Shouyou and Tsumu-nii share a lot of secrets, which makes Tsumu-nii Shouyou’s bestest best friend in the whoooole world.
~~
One day, Shouyou wakes up with his peepee hard.
It’s not as rock-hard as Tsumu-nii’s, but it’s something. This means Shouyou is an adult now. Or something close to it.
Shouyou spends the whole school day giddy with excitement, his chests puffed out. He’s dying to tell Tsumu-nii about this. He almost slipped and blurted this new development out to Oikawa-sensei because he’s just so excited about it during recess, but he did not. Shouyou is being good.
After school, Shouyou runs back home as fast as he can. He waits for the twins’ arrival on his house’s genkan. When the sliding door opens, he almost pounces on Tsumu-nii. Tsumu nii-chan welcomes him in his big, strong arms with an oof.
“What’s up, Sho-chan?” He asks, sounding pleased while he messes Shouyou’s hair around. Shouyou can see Samu-nii rolling his eyes. Samu-nii is used to them being all over each other a lot.
“Tsumu-nii, let’s bathe together!”
“Ooh?” Bathing together is their secret code for “I have a secret to tell you!”
Tsumu-nii told him about his ticklish part when they were bathing together. Or how the secret behind how Tsumu-nii can run so fast is by mass-aging his butts. Tsumu-nii grins at him, then turns to Samu-nii.
Samu-nii sighs while he puts his shoes in the cupboard. “I’m gonna play the PSP upstairs,” he says, then he heads down the corridor to the stairs at the end of the house. “Please don’t wet the hallway on your way out.”
Tsumu-nii then shouts his okay and lifts Shouyou up, up, Shouyou laughs out loud from how high he is. Then he almost runs to the bathroom with Shouyou dangling on his neck. The bathroom is on the corner of the first floor, so they don’t need to climb the stairs after Samu-nii for it.
In the changing room, he carefully puts Shouyou down, then helps him out of his clothes. He likes to tickle Shouyou with his lips whenever he’s unclothing Shouyou. Shouyou giggles every time Tsumu-nii’s lips slide close to his armpits or his neck or his stomach, and then Tsumu-nii would giggle back—it’s almost like a ri-too-al between them.
The cleaning part always doesn’t take long: Tsumu-nii finishes washing his hair and his body in a flash, and then does the same to Shouyou. For some reason he never wants to stay out of the bathtub for too long whenever they bathe together. When Shouyou asked why, he just mumbled something like still a bit too young— Shouyou doesn’t really understand, but he never asks further because he doesn’t want to sound dumb.
Today is the same. It is when they’re both submerged in the lukewarm water (Shouyou wanted it fast so he said the water doesn’t have to be too hot) that Tsumu nii-chan twines his arms around Shouyou’s waist and pulls him closer. “So?” he asks. There’s this slanted smirk that Shouyou loves on his face.
Shouyou grins, then he cups his small hands on Tsumu-nii’s ear. No one would hear them here, but this makes it as if it’s a top secret (it is!) and Shouyou likes it that way. He slowly draws closer and he whispers, “My peepee is hard this morning.”
Tsumu-nii doesn’t react. Shouyou’s confused.
He was expecting a big cheer from Tsumu-nii, because doesn’t this mean Shouyou is an adult now? Not a bit too young anymore. But then Tsumu-nii slowly turns to him, and he has this big, big smile that Shouyou doesn’t recognize. But he looks so happy, Shouyou can’t help but smiles back at him.
Suddenly, Tsumu-nii surges and kisses him. Not the kisses that tickle, this is the one like their goodnight kisses. Shouyou’s lips are already wet from water, and then Tsumu-nii’s lips start to move, almost covering Shouyou’s whole, his spit makes them even wetter. Shouyou follows the movement with his lips, like how Tsumu-nii taught him.
But then Tsumu-nii’s kiss becomes a bit frantic and Shouyou can feel a tongue licking around his mouth. He hums questioningly, though Tsumu-nii can’t seem to hear him—he continues prodding his tongue against Shouyou’s lips, teeth, inside his mouth, then sliding it against Shouyou’s tongue. It feels nice, though a bit weird with how wet it is. Or how the sounds of their tongues echo in the bathroom. It hurts a little bit too. And Tsumu-nii’s heavy, trembling breaths make it a bit funny, but Shouyou feels his head becoming lighter, and he quite enjoys the sensation. Shouyou’s tongue isn’t as long as Tsumu-nii’s, but still he tries to press it back against Tsumu-nii’s lips. He can feel when the lips on the tip of his tongue spread—Tsumu-nii’s smiling—and Tsumu-nii hums this low, happy sound. Oh, Shouyou likes this.
After some time though, Shouyou is out of breath. He weakly slaps on Tsumu-nii’s neck repeatedly so he’d release his tight grip from Shouyou’s waist.
When he finally does, Shouyou wheezes, “Whuzzat?”
“A kiss.” Tsumu-nii nuzzles his cheek and plants another kiss—the normal kind—on his lips. He’s still grinning really wide.
“But it’s not sleepy time yet?”
“This is the special kind. Can be done during the day too. But,” Tsumu-nii pouts, cocking his head, “I can only do it with you, and you can only do it with me. Okay?”
Shouyou frowns, still a bit dizzy. “Why?”
“Because it’s a kiss reserved for someone you love. Does Sho-chan love me?”
This is a question Shouyou knows the answer to, because they’d done this a lot of time. He grins and buries his face in Tsumu-nii’s neck. “The most in the whole world.”
“That’s right, Tsumu-nii loves Sho-chan too,” Tsumu-nii says, rubbing Shouyou’s back. He gently turns Shouyou’s face with his other hand, and when Shouyou looks at him, Tsumu-nii has his tongue out. He signals with his chin for Shouyou to do the same, so Shouyou does.
Tsumu-nii moves to twine their tongues, slowly this time. It isn’t like the “kiss” earlier, they’re just swirling the tip of their tongues together. Though because Shouyou’s way smaller, he can only move a little bit. Tsumu-nii’s eyes never seem to leave Shouyou’s face, and the way he looks makes Shouyou’s belly tingly and weird. Just when Shouyou’s jaw starts to ache, Tsumu-nii stops and smiles again.
“Is it nice?” He asks.
“‘Snice..”
“Never tell anyone about it, okay? It feels good only if no one knows about it.”
A new secret, then. Shouyou giggles. “Mkay.”
“This is my present for Sho-chan.”
Now it’s Shouyou’s turn to cock his head. “For what?”
“About that.” Tsumu-nii pulls Shouyou closer until he sits on Tsumu-nii’s lap. Shouyou can feel something hard pressing against his thigh. Curious, Shouyou gazes down, but the murky water makes it hard to see. Tsumu-nii continues, “so what’s about this hard peepee?”
“Yes!” Shouyou snaps his head back, grinning. “‘M an adult now.”
“What does it look like?”
“What does it look like?” Shouyou repeats, unsure. His peepee is soft now, though it’s been twitching like crazy when they were “kissing” earlier. “I can’t show you now,” he says, feeling frustrated in himself.
Tsumu-nii doesn’t look disappointed though. If anything, his smile takes a teasing gleam to it. “Hmm,” he says, and then he rises and sits at the edge of the tub, leaning against the wall. “Does it look like this?” he says, then he holds this big, fat pipe-looking thing in his hand, pointing the soft-looking tip at Shouyou.
Then Shouyou realizes it’s Tsumu-nii’s peepee and he gasps, hands on his cheeks. Tsumu-nii chuckles at his reaction.
Of course Shouyou’s seen Tsumu-nii’s peepee. It’s huge compared to Shouyou’s , but it usually hangs heavy and looks soft and springy, and only as big as around both of Shouyou’s fists (Tsumu-nii makes him measure the size of his fists that way, a few weeks ago). This though, this is as huge as Shouyou’s head. Shouyou can feel his mouth forming an ‘o’.
Tsumu-nii seems to be satisfied with Shouyou’s attention. He slides his hand up and down, slowly, while his other hand messes with Shouyou’s wet hair. “Yeah? You like it?”
“How’s it so big?” Shouyou asks, can’t quite contain the awe in his voice.
“When adults feel good, they get big here,” Tsumu-nii explains.
Shouyou blinks. “You’re feeling good now?”
“Yes, because I’m with Sho-chan.” Tsumu-nii’s grin grows wider. “I feel good whenever I can touch Sho-chan.”
Shouyou blinks again. Tsumu-nii’s like this because of him? There’s a sense of pride that surges inside Shouyou’s chest, though he doesn’t understand why. But then he thinks, he wants to make Tsumu-nii feels good all the time. So Shouyou moves closer, and with some hesitation—more because he’s not sure if he’s doing this adult thing right— he raises his hand to touch Tsumu-nii’s peepee. Shouyou can hear when Tsumu-nii inhales and stops breathing.
The thing’s hard, but Shouyou knows that. He’s tickled Tsumu-nii’s ticklish part—Tsumu-nii’s ticklish on his peepee, the thought makes Shouyou giggles a little—plenty of times before. But what he didn’t know, and he can feel now as his fingers circle around it (though his thumb can’t meet his pinky), is that it’s—hot. And pulsing. It’s like it’s alive.
“Is this good?” Shouyou whispers. He doesn’t know why he’s whispering again, but the look on Tsumu-nii’s face tells him this is gonna be their toppest secret yet.
“Very.” Tsumu-nii’s voice is hoarse, strangled. Like when he’s holding his laugh. “Can you move your hand? Up and down.”
Shouyou does.
“Grab it harder, Sho-chan.”
Shouyou does, his tongue poking out in concentration.
“Fuck, yeah, like that,” Tsumu-nii says. Shouyou gasps because Tsumu-nii just said a bad word . But he figures him becoming an adult means bad words are okay too now.
Tsumu-nii’s face is getting redder, and he looks at the way Shouyou’s hand grabbing his peepee so intensely. Shouyou’s arm is getting tired now, but he doesn’t want to disappoint Tsumu-nii, so he brings his other hand out of the water to join in, rubbing and squeezing with all his strength. Tsumu-nii hisses, but then he pats Shouyou’s head as praise.
“Tsumu-nii, your peepee is too big .”
“It’s not ‘peepee’, Sho-chan,” Tsumu-nii says, his breaths heavy he struggles with it. “It’s a ‘cock’.”
“Cock?”
“Yeah,” Tsumu-nii nods. “Can you say that again, but with ‘cock’?”
It takes a moment for Shouyou to understand what Tsumu-nii asked of him. The warm water is getting into his head, and now his peepee is starting to get hard too. His belly feels funny. “Tsumu-nii… your cock is too big?” It comes out more like a question, but Tsumu-nii seems pleased.
“Yes,” he hisses, the s long and low. He moves to palm his peep—his cock, covering both of Shouyou’s hands with his own. And then he starts stroking, pulling Shouyou’s hands with it. He grunts these low “ah” and “hng” sounds a lot, and Shouyou flushes hearing them ringing in the bathroom, with the weird squech squech sound from Tsumu-nii’s cock. This all feels…. Weird. Weird but good. Tsumu-nii is feeling good, and Shouyou is, too.
“Sho-chan,” Tsumu-nii pants. He licks his lips. “Say that thing again. How do you think my cock looks?”
Shouyou blinks a drop of water from his hair out of his eyes, moving closer so he can rest his elbows on the side of Tsumu-nii’s thighs. He peers up, and from this angle Tsumu-nii looks—wild. Naughty. His eyes are different from usual. Shouyou loves it.
“Tsumu-nii’s cock is so hard,” he says.
“Yeah? And?”
“Your cock is so huge and feels hot.”
Tsumu-nii speeds up his movement, Shouyou struggles to keep up. “You like it?”
Shouyou likes all of Tsumu-nii’s. “I love Tsumu-nii’s cock.”
Tsumu-nii holds his cock down, the tip pointed at Shouyou. “Lick it then.”
Shouyou is surprised to see that it’s— wet. But not with water, it’s not pee either. It looks thicker than that. Does this mean Tsumu-nii wants Shouyou to lick the thick liquid off his cock? Shouyou can do that. He puts his tongue out, and he carefully licks the slit where the liquid seems to be the thickest.
Tsumu-nii moans this low, trembling sound, startling Shouyou to look up. “It hurts?” Shouyou whines.
“No. No, it’s really good. Do it again, Sho-chan, fuck. ” Tsumu-nii begins to stroke his cock again, this time letting the tip stay down low within Shouyou’s mouth’s reach. “Lick my cock, suck the tip,” he urges.
Shouyou complies, this time savoring the weird salty taste of the liquid. It isn’t so bad. Feels like licking on a savory lollipop. Then he remembers Tsumu-nii told him to suck on it, so he wraps his lips around the soft part of Tsumu-nii’s cocktip—it’s so thick Shouyou has to open his maw with all he’s got—and he sucks.
Tsumu-nii’s moan is so loud Shouyou almost releases his lips again. But Tsumu-nii said that that sound means he’s feeling really good, so Shouyou continues sucking and licking when he needs to take some breathers. The slit produces more of this salty liquid and Shouyou’s starting to enjoy the taste, gulping on it. Moreover Tsumu-nii keeps saying all these pretty words like “good boy” or “so, so good for me, Sho-chan” or “aaaah, that’s it, feels so fucking good , you’re the best”.
When he flicks his eyes up, Tsumu-nii only has his eyes on him. Like Shouyou’s all Tsumu-nii cares about in the world. And that—more than the soft, salty tip in his mouth, more than the hard, hot cock he’s squeezing with both of his hands—elicits a similar moan that comes from within Shouyou’s chest. Tears brim in his eyes, and his own cock feels itchy.
Tsumu-nii’s eyes go impossibly wider. He grins wildly, “Yeah? You really fucking love that huh? Like sucking on— ah— Tsumu-nii’s cock?”
Shouyou whines with what he can, with the cock still in his mouth, nodding, gazing up at Tsumu-nii.
“Fuck, I’m close,” Tsumu-nii says. Shouyou doesn’t understand, but Tsumu-nii starts quickening his hands again, Shouyou jostles with the movement. His hands are pressed so tightly against Tsumu-nii’s cock, he can feel it twitching. “Fuck, yeah, that’s it. That’s it. Take my cum, you slutty kid. Y’gotta take my cum.”
Shouyou doesn’t know what ‘cum’ is. What is he supposed to take? He frowns, humming his question.
“Lick it again, Shouyou. Come on, lick the tip for me, baby,” Tsumu-nii says tightly. His breaths come in heavy exhales.
Shouyou still isn’t sure what he's supposed to do, but this, he knows. He swirls his tongue around the slit, like he did earlier with Tsumu-nii’s tongue. Just as wet, with him slobbering spit all about Tsumu-nii’s cocktip.
“Oh, baby. You’re so fucking good,” he moans, “you were so born to be a cocksucker.”
More words Shouyou doesn’t understand, but this time Shouyou can’t really bring himself to ask. Tsumu-nii’s feet, which are still underwater, prod against his little cock and it feels like Shouyou’s brain has melted off and down into his cock. Shouyou squeaks, startled but also exhilarated—it feels like nothing he’s ever felt before. The pleasure makes him roll his eyes upwards, while Tsumu-nii’s toes continue twiddling his hard little cock.
“You’re such a pervert. ” Shouyou knows it’s a bad word, but Tsumu-nii says it like it’s a compliment, with a wide grin. “ Fuck, what a fucking sight. A child suckling on my cock.”
And then Tsumu-nii swings his hips a little and shoves his cock deeper into Shouyou’s mouth. Shouyou gags, the entire space inside his mouth filled entirely by Tsumu-nii’s cock, solid and heated. There’s a lot of Tsumu-nii’s cock that Shouyou can’t possibly cover with his mouth, and Tsumu-nii continues to rub their hands across that part. The cock squelches against the collecting spit in Shouyou’s mouth.
“Ah, yessss, this is it. This is it,” Tsumu-nii pants, grinding slowly inside Shouyou. “I’m coming. I’m coming. Be a good boy and take my cum, baby. Drink it for me.”
Shouyou blinks, half confused and half dizzy with his own cock pressing still against Tsumu-nii’s toes. But then he feels first when Tsumu-nii’s cock throbs against his lips, and then the tip of Tsumu-nii’s cock spurts hot, slimy liquid across his tongue.
It feels very alien to his tongue, Shouyou reflexively chokes and coughs, feeling breathless. Tsumu-nii seems to take pity on him and pulls his cock out, but just as it’s outside, it pumps more of the slimy liquid across Shouyou’s face. It lands on Shouyou’s nose and cheek. Now that Shouyou can see when it bursts out of the slit of Tsumu-nii’s cock, he knows the color’s white and thick.
“Whatzzthis?” Shouyou whines, his words slurring because he still has his mouth open. The white liquid is still coating his tongue.
“It’s my cum,” Tsumu-nii says. “Drink it for me, baby.”
Shouyou whines harder because it tastes weird. Tsumu-ni tsks, and Shouyou almost flinches from it—Tsumu-nii never tsk-ed on him. Then he presses Shouyou’s mouth close and covers his nose and mouth, his other hand lifting Shouyou’s chin up. Shouyou cannot breathe like this.
“It’s my love juice for you. It’s proof that I love you,” Tsumu-nii says, impatiently. “Fucking drink it.”
Shouyou sobs, because if this liquid means Tsumu-nii loves him, then Shouyou wants to accept it. He doesn’t want Tsumu-nii to hate him. He forces himself to gulp the slimy, bitter liquid down his throat. When he’s done, he whimpers against Tsumu-nii’s palm.
“Open your mouth,” Tsumu-nii commands, as he uncovers Shouyou’s face and Shouyou can breathe normally again.
Shouyou complies, putting his dry tongue out.
The satisfaction that colors Tsumu-nii’s face as he looks at Shouyou in that moment is indescribable. Shouyou thinks he’ll never forget how happy Tsumu-nii looks, and in turn, how happy it makes Shouyou feel.
“My good boy,” Tsumu-nii coos. “My good slutty boy. Likes drinking my cum. C’mere, clean my cock for me baby.” He shimmies closer, rubbing his wet cock around Shouyou’s face, collecting the cum that landed there with the tip and bringing it to Shouyou’s mouth.
Shouyou closes his lips around the white-stained tip, lapping his tongue against it. Tsumu-nii’s praises run on, and Shouyou is getting used to the flavor of this ‘cum’ thingie. He thinks he can grow to like it. Especially if Tsumu-nii keeps calling him “my favorite boy” and “baby” like this.
Once Tsumu-nii’s cock is cleared off the liquid, he slides down back into the water. Hugging Shouyou tight. Shouyou’s own cock has softened somewhere along the way, but the satisfaction that vibrates out of Tsumu-nii is affecting him as well. Shouyou grins.
“Good?” he asks. His voice is scratchy.
Tsumu-nii smacks a kiss on his cheek. “The best. ”
Shouyou giggles, sated and happy, and he sinks deeper into Tsumu-nii’s hug. It’s always relaxing here, between Tsumu-nii’s arms, especially when he gently starts mass-aging Shouyou’s butts, like now. Shouyou sighs.
“Shouyou,” Tsumu-nii says, just when Shouyou feels like he’s falling asleep. “You know you can’t tell anyone about this right?”
Shouyou hums. He lifts his head up, and kisses Tsumu-nii’s lip in agreement. “It's a secret,” he giggles.
