Aizawa cheats on Yamada with their son, Hitoshi.

Yamada also cheats on Aizawa with their kid.

Neither of them know about the other, both of them filled with guilt that eats away at them every day.

Hitoshi wants to keep it that way.

(Content warnings: cheating, incest, somnophilia, mentions of alcohol, Hitoshi is underaged.

Not really a "content warning" per say, but Deaf Hizashi is also a big part of this.)

There's something about being the center of attention that gets Hitoshi off.

He'd always known that his parents loved him, of course. They were never shy about that. But the fact that both of them would break their marital vows to fuck their only child...

Nothing makes Hitoshi feel so special. So loved.

In the evening, when all three of them are home, Aizawa sometimes calls Hitoshi into the other room and pushes him against the wall, kissing him hard as he grinds into him, all while Yamada is sitting in the living room, just out of sight.

Aizawa leans in and right against Hitoshi's ear murmurs in a rough, guilt-filled voice, "I can't fucking get enough of you."

Hitoshi comes in his pants every time he says it. Nothing gets him off harder.

Maybe he's fucked up. He loves it. His parents are so loyal to each other. So very in love. Yet, it's Hitoshi who can get them both to break that loyalty to each other. Neither of them can stop. They just keep coming back, whispering how irresistible Hitoshi is, how loved he is.

The fact that it's impossible for the two of them to keep their hands off of Hitoshi, no matter how loyal to each other they are, gets him harder than anything else.

No matter how much Hitoshi pushes, they always respond in earnest. So Hitoshi tries his luck.

One night Aizawa and Yamada go out drinking.

Hitoshi thinks it's for some sort of birthday party for a fellow teacher. He doesn't know. He was a little too horny to properly pay attention when they told him.

Drinking means drunk. Loose. It means he can press his luck.

Hitoshi keeps himself on edge as he's home alone. He climbs into his parents' bed, rolls around in the blankets and pillows, getting his scent all over theirs. He grinds his clothed cock against the pillows, whimpering but not letting himself cum.

That's where he stays, alone in that bed, laying right between his parents' spots, waiting for them to get home. He has no intention of moving.

It's around midnight when he hears the telltale scuffling at the door, the sounds of a slightly drunk couple trying to pull themselves together before coming home. He hears Yamada's giggle. Hitoshi's excitement rises.

The door unlocks and two stumbling bodies come in. Hitoshi's left the bedroom door open and he can hear everything. They're not extremely drunk, not enough where they're completely stupid and sloppy, but they're drunk enough that they're loose. pliable. Moldable.

They come into the bedroom and stop.

Hitoshi fake rouses, blinking his eyes open and giving a yawn, like they'd just woke him up. The two of them stare at him, looking like a little bit of a mess, both their eyes huge in expressions Hitoshi knows well. Guilt and arousal.

"I just... had a bad dream," Hitoshi says quietly, having perfected the art of looking pitiful. The two of them like the chance to be the caretaker and comforter. Acting innocent and scared is sure to work. "Can I please stay? Please?"

They both break immediately.

Yamada gives him a small smile, "Of course you can stay. Come're, kiddo."

Hitoshi smiles back. Yes, of course he can stay. Of course. Would they ever say no to him?

"Thank you," Hitoshi says quietly, going to Yamada when he sits on the bed and opens his arms to Hitoshi. He looks at Aizawa, giving him a big-eyed look, and notices how red Aizawa's face is.

"It's alright," Aizawa tells him softly. "You know you're welcome in here anytime."

Hitoshi smiles wider.

Yes, anytime he wants. No matter what.

Perfect.

Before he knows it, he's sandwiched between them. Aizawa's chest is against Hitoshi's back, spooning him. Hitoshi's chest is against Yamada's, all three of them laying cuddled together in the bed. Right where Hitoshi wants them to be.

He'd pretty sure Yamada fell asleep the moment his head hit the pillow. The man is completely Deaf and the second he turns off his implants, he can't hear anything. He always falls right asleep.

Aizawa on the other hand...

He takes a while.

Even when drunk.

To be completely fair, Hitoshi waits ten minutes. He can see the glowing numbers of the digital clock over Yamada's shoulder. But Aizawa doesn't fall asleep. In fact, he seems just as distracted as Hitoshi.

Aizawa can't seem to keep his hands off of him.

Like always.

Exactly the way Hitoshi wants it.

"Daddy," Hitoshi whispers quietly when Aizawa's hand ghosts over his hip, running down his side and over the curve of his waist. He sighs and wiggles back, pushing against Aizawa.

Aizawa freezes. He can feel his fingers shake.

Hitoshi knows he's listening. They both are.

Against Hitoshi's chest, Yamada lays as still as ever, breathing rhythmically, giving no indication of having noticed the two of them moving.

Hitoshi smiles. Aizawa's fingers creep under his shirt.

"Shh," Aizawa tells him softly, like there's someone here who's going to hear. He stops again, his fingers resting on Hitoshi's stomach, "We shouldn't."

Hitoshi isn't deterred, "Please?"

That's all it takes. Aizawa's lips press against his neck. His hands feel him up.

Hitoshi's body is quick to respond. He's been edging himself all night, keeping himself from coming as he waited for his parents to get home. His cock twitches and hardens and when he pushes back again, he can feel the bulge in Aizawa's loose pants.

"Careful," Aizawa warns him in a low voice, hot breath ghosting over his skin, sending a shiver up his spine. "Don't wake Hizashi."

Hitoshi tries to sill himself a little. He can't help himself, though, "Do you like this? Touching me in bed when he's right there?"

He gets a quiet growl in response, and Aizawa bites the side of his neck, sucking harshly. Both of them leave marks on him all the time. They just think that Hitoshi hooks up with kids at school besides them.

Which isn't untrue, but he never goes very far with them.

Aside from kissing and the occasional handjob, he reserves himself to his dads.

His holes and his cock are for them to use. Hitoshi's body belongs to both of them, even if they don't know it.

Playing around is fun but he loves his parents much, much more.

He can feel the mark Aizawa leaves on him without having to look in a mirror. He smiles, letting out a happy sigh. Aizawa's hand pushes up his shirt, and he brushes a thumb over a nipple, making Hitoshi moan.

Hitoshi reaches back, grabbing Aizawa's hand, and puts it on his hip.

Aizawa gets the hint.

His fingers curl against Hitoshi's hip and he pulls him back, pulling his waist away from Yamada. His ass slams into Aizawa's groin and he hears a loud, unrestrained moan behind him.

Aizawa keeps him there and rolls his hips against his.

His thick cock grinds against Hitoshi's ass, the material of their sweatpants thin enough that Hitoshi can feel every inch of it.

Not that it matters much if he couldn't, because Aizawa's next move is to yank Hitoshi's pants down and then his own.

Neither of them have any underwear on. Aizawa's hot, hard cock is grinding shamelessly against Hitoshi's bare ass.

All while Aizawa's husband is right next to them, fast asleep.

He won't be for long.

"I can't fucking stay away from you," Aizawa murmurs against his neck, the rolling of his hips getting rougher and rougher. His cock sits right between Hitoshi's ass cheeks, the head pushing between his thighs, wet and throbbing. "I love you too fucking much."

Aizawa always gets so much looser when he's drunk. Hitoshi hangs onto every word. Aizawa's desperation makes him feel so wanted. So loved.

"Told Hizashi I was gonna fuck him when we got home..." Aizawa mutters against him. "But I thought about you instead."

Hitoshi nearly comes right there, without being touched. He squeezes his thighs together to stop himself, reminding himself that there's more that he wants.

What Aizawa's saying is better than any dirty talk.

Hitoshi's hands shake a little when he reaches out. His hands had been against Yamada's chest, but he slides them down slowly so as not to set Aizawa off. He either succeeds, or Aizawa's too busy grinding against his ass to notice.

"Will you fuck me now?" Hitoshi asks with a sly smile. He wishes he could see Aizawa in the darkness.

His hands slide down to Yamada's loose pants. He rubs the palm of his hand over his clothed cock, feeling it twitch and jump at the familiar touch.

Hitoshi licks his lips. He hadn't expected Yamada to be so quick to respond. He's definitely still asleep- Hitoshi checks- but even while asleep, his body still recognizes Hitoshi's touch.

He sleeps with Yamada in here when Aizawa's away on missions.

He makes the anxiety of not knowing if Aizawa's going to be okay go away by fucking him into the mattress with his pierced cock, on Aizawa's side of the bed.

Yamada fucks him as many times as it takes to make him feel better, and then some.

Always whispering the same things to Hitoshi- how much he loves him, how much he thinks about fucking him when he's with Aizawa and when he's not.

He says filthy things, about how he steals Hitoshi's dirty underwear out of his hamper and returns them far more used than before. He says he can't even try to stay away from Hitoshi- that it's simply impossible. Hitoshi wishes he could record it all. He'd never need porn again.

Hitoshi rubs at Yamada's cock, gently running his fingers over it through his pants. It quickly hardens under his touch, tenting under the thin fabric.

Moving as little as he can, Hitoshi slips his fingers under the waistband and pulls down, his half-hard cock popping out.

Hitoshi is nearly shaking with excitement.

By now Aizawa has become completely undone. His face is pressed against Hitoshi's neck and he's rubbing on Hitoshi's ass without abandon.

It's time for the next part of his plan.

"Daddy," Hitoshi calls out quietly, making Aizawa freeze up. Hitoshi takes Yamada's cock into his hands, stroking it from base to tip. "I'm ready for you already."

Aizawa's fingers find their way back, between Hitoshi's ass cheeks, and against the plug he has nestled in there.

"Hitoshi," Aizawa hisses, his voice trembling. "We shouldn't."

"It's okay," Hitoshi assures him, Yamada's cock fully hardening under his touch. Against his chest, he feels his breathing hitch. "Please. I've been waiting all night. He won't wake up. I'll be good."

Aizawa makes a choked sound, somewhere between a moan and an attempt to actually say something. His fingers tighten around the plug and his pulls slowly, Hitoshi's ass stretching as it pops out.

"You're always good," Aizawa breathes. It's music to Hitoshi's ears.

Yamada's breathing hitches again when Hitoshi squeezes his cock and strokes the head. He really wishes he could sink down and wrap his lips around it while Aizawa fucks him, but that would definitely give him away. He'll have to settle for this, but he'll make it worthwhile

Aizawa slips a long finger into his ass.

Hitoshi moans lewdly and bucks against him, intentionally rubbing his cock against Yamada's leg in the process. The pleasure sparks up his spine, making him feel better than ever.

"Fuck, you're ready," Aizwawa swears, the arousal laying heavy on his voice. They can make all the noise they want- Yamada can't hear without turning his implants on.

"Please," Hitoshi begs, rubbing the head of Yamada's cock, smearing the precum there down his shaft.

Aizawa can never say no to him when Hitoshi says please.

Neither can Yamada.

It's his secret work. The one he can use to get them to do whatever he wants.

Aizawa doesn't argue. He lines his cock up with Hitoshi's lubed, stretched ass, and pushes in.

Hitoshi draws in a sharp gasp as Aizawa slides into him. Every moment of it is exhilarating, far beyond what Hitoshi had been imagining earlier tonight.

He can't believe they're doing this.

Yamada is right up against him.

Aizawa's the one who crawls into bed with him some nights, leaving Yamada and coming to Hitoshi's room, climbing under the covers with him and holding him close. It's not like they haven't fucked in bed before. It's that Yamada's never been so close. So close to finding out.

He squeezes Yamada's cock and hears him gasp. Aizawa doesn't stop, not seeming to take notice of it. He bottoms out in Hitoshi's ass, fully seated inside of him. He stays like that for a moment, still.

Hitoshi tilts his head up and sees Yamada's eyes flutter.

Aizawa's definitely not looking. His face is buried in Hitoshi's neck. He probably actually looks asleep right now. It's not like Yamada can hear his gasping and groans. He's just barely moving, giving these small little thrusts into Hitoshi's ass.

Hitoshi runs his thumb against the head of Yamada's cock and leans up, moving just a little to press his lips against his. Aizawa's too busy fucking him to notice and Yamada doesn't respond for a moment, but slowly wakes up as Hitoshi presses his tongue into his mouth.

He moans into Yamada's mouth, Aizawa daring to pull out a little more and slam back in. Aizawa's arms are wrapped tight around Hitoshi's hips, pulling him away from Yamada. He's kissing Hitoshi's neck, biting and leaving marks, not paying attention to Hitoshi kissing his husband.

Yamada starts to respond, slowly at first. He's waking up. His cock throbs in Hitoshi's hand as he begins to understand.

Yamada kisses him back, his tongue tangling with Hitoshi's, and Hitoshi shivers. Yamada has no idea that his husband is buried in Hitoshi's ass right now.

Yamada stays quiet, even when they part, clearly remembering that Aizawa's in bed with them. Both of them think the other is asleep. Perfect.

They're cheating on each other at the same time, in the same bed. Both with their only child.

Hitoshi tries to reposition himself a little without setting either of them off. That's the hard part, unfortuantely, but Hitoshi's more than up to the challenge. He's not going to let his two sloppy, drunk, horny dads go to waste.

He pulls his lower half forward a little, moving from where Aizawa has him held tight. Aizawa groans and moves with him, sloppily thrusting into Hitoshi's hole. His fingers dig into Hitoshi's ass cheek, leaving little scratch marks from his hip to the small of his back.

As quiet as he can be, Hitoshi unwraps a hand from Yamada's cock and pushes forward, closing in most of the distance between them, his front flush against Yamada, his back flush against Aizawa.

With a wicked, satisfied smile, Hitoshi pushes a thigh between Yamda's legs.

Yamada gets the hint and grinds his cock against Hitoshi's thigh. Hitoshi whines, Aizawa taking that moment to fully pull out and slam into him, shoving him harder against Yamada.

Aizawa might be a little drunker than Hitoshi thought.

Yamada responds in earnest, roughly fucking his cock against Hitoshi's thigh, clearly thinking that it was Hitoshi who'd thrusted against him like that.

It pushes him back against Aizawa, making him sink deeper inside of him, the head of his thick cock brushing his prostate.

Hitoshi quickly realizes one thing that he didn't even intend-

He has himself in a position between them where each movement from one is going to push him further against the other. Each thrust from Aizawa causes him to grind harder against Yamada.

Each thrust from Yamada rubbing his pierced cock against him pushes him back against Aizawa and causes his cock to sink deeper into him.

He's lucky the two of them are drunk enough that they think he's the one doing it all.

Part of him can't believe he's doing this.

The other part of him can't believe it's working.

They can't stay away to him. They'd never say no to him. They're totally willing to cheat on each other with their son while in the same bed.

Hitoshi whimpers loudly, another deep, hard thrust from Aizawa sending him slamming into Yamada. Yamada matches it, the pierced head of his cock pressed hard into Hitoshi's thigh and hip, leaking precum all over him.

Hitoshi's cock grinds against Yamada's stomach every time he's pushed against him. It's almost too hot to handle and he shakes and shakes, Aizawa fucking into him harder and Yamada grinding against him rougher with each passing second.

Suddenly, Aizawa grabs his hair and forces his head back, shoving his tongue into his mouth and kissing him deep.

Still not knowing what's going on, Yamada wraps his hand around both their cocks and strokes them, Hitoshi moaning into Aizawa's mouth.

They have no idea.

"Fuck-" Aizawa swears when he splits from Hitoshi, breathless.

Hitoshi barely waits a moment. He turns and shoves his mouth against Yamada's, his hand stroking them both as Aizawa continues to shove Hitoshi against him.

He wonders if Yamada can taste Aizawa on his lips.

God, he hopes he can.

"Thought about you so much tonight-" Aizawa gasps out from behind him as Yamada shoves his tongue down Hitoshi's throat. His thrusts are harder than ever before, each making him slam into Yamada. "-Kinda just wanted Hizashi to fall asleep so I could go fuck you."

Hitoshi can't say anything. He just whimpers. Yamada's hand squeezes them. He can feel the piercing in the head of his cock press against his shaft. Hitoshi's hips jump with each movement, until he's humping Yamada's hand and cock desperately.

"Really shouldn't but god, I can't stop thinking about you," Aizawa goes out breathlessly. From the way his cock throbs in his ass, he's getting really close. "Wish I could just sit you on my lap and fuck you all day long. I can't fucking- get enough-"

Hitoshi cries out, Aizawa's words sending him over the edge, his body buzzing with over stimulation.

Aizawa follows immediately. Hitoshi's ass clenches and he buries himself into him one last time.

Yamada cums with his husband, ironically, spilling all over Hitoshi's stomach.

All three of them lay there together.

Two parents and their only child.

Each of them thinking the other is asleep, Hitoshi being the only one who knows.

Yamada's never loud after sex and he's only loud during sex when he can actually hear himself. He barely makes a noise when he doesn't want to. He's breathing hard, but not panting, not like Aizawa is.

Hitoshi's world spins. He barely realizes it when Yamada leans down and kisses him.

It's short. Chaste.

Aizawa pulls out of him slowly, just in time for Yamada to reach down and gently pull Hitoshi's pants back up, obviously not know that his husband just came inside him.

Aizawa touches his hip a moment later, narrowly avoiding brushing Yamada's hand. He clearly had the same idea, but relaxes once he feels that Hitoshi's already dressed again.

Then he quietly asks, in a guilt-filled voice, "Is he asleep?"

"Y-Yeah," Hitoshi gets out, staring up at Yamada, who's staring down warmly at him, his eyes already half-closed again. "He's asleep."

He will be soon. So it's not that bad of a lie.

Hitoshi has a mess of cum on his stomach and another mess of cum dripping out of his ass. But he makes no move to get up and clean himself off. Instead he lays there, between his parents, mind spinning as he realizes he got away with this.

Yamada's eyes are closed and Hitoshi's almost positive he's asleep by the time Aizawa leans over him and softly kisses Hitoshi, in the exact same way that his husband had done only a few moments earlier.

Finally, Aizawa settles and soon enough, is asleep.

Only then does Hitoshi let himself grin, his heart beating hard.

He'd gotten away with it.

He finally relaxed, both Aizawa and Yamada holding him, and drifted off into a restful sleep.

He couldn't wait for the morning, to see the guilt all over their faces, to see they way they'd dote on both Hitoshi and each other to make up for it. He couldn't wait to hear about how bad they felt, even though they couldn't resists him, how they just loved him too much.
