I'm gonna join the shota Nai x adult vash, only that I particularly enjoy it more when Nai is a bit older. So: 15 yo Nai x 23 yo Vash.

Vash who's on his last year of college and is still a virgin. He's had some opportunities to fuck, but chickened out in the last—

moment. He's gained the reputation of the university dicktease. Getting hot anyone and then running away the second it seems to escalate.

Vash doesn't do it in purpose. Not really. He likes the teasing and flirting, the playfulness of it all. But when his companions suggest him—

to go somewhere private, he freezes and doesn't want to continue, so he runs away.

It's been 2 years now, of doing it. His friends tell him he should stop if he is never going to do it, but Vash either can't help it, or gets hit on so many times a night, it's impossible for—

him to deny everyone.

It's not that Vash doesn't want to have sex. He does. But all the people he's known... They don't do it for him. Maybe he should be less picky, but the idea of fucking with someone with who he doesn't give a damn about, doesn't feel right at all.

So—

whenever he goes out, he always returns home alone, kinda horny, and sad. He lives close the the university, so he doesn't need a dorm in the campus. Besides, he loves to get to see his baby brother every day. Specially the nights he returns after a party.

Vash likes to go to—

Nai's room and kiss his forehead goodnight, even if his brother has been fast asleep for a few hours when he comes back. Still, he enjoys babying his little brother, combing his hair through his fingers and kissing him on the temple or the cheek. Sometimes even caressing his—

face and lips. They're so soft. Rosy and squishy. Vash would be lying if he said he hadn't thought about what it'd feel like to press his mouth against them. But the idea is so wrong, whenever these ideas cross his mind he goes to his room as quick as he can and masturbates, so—

he gets the fire inside to settle and his mind to understand how fucked up is to want to touch his brother like that.

However, it's been happening for some months, now, and it doesn't seem to have gotten better. It's gotten worse, tbh. What he at first only thought when he saw—

Nai asleep, lips parted and angelic expression, soon moved onto when Nai was awake. Mischievous grin on his face, eyes bored and calculating. Always on Vash. Always igniting desires Vash shouldn't have for his baby brother.

It was sick. It was wrong. It was terrible. Still, it—

was Nai's name that was on his mouth whenever he fucked himself with his dildo. Nai. Always Nai.

And tonight is no better. After returning home from another party, panties soaked from the teasing with a blond guy that reminded Vash of Nai, and having given his brother a kiss—

goodnight, he finds himself on his bed. Legs parted and dildo deep inside his pussy. Obscene sounds coming from his mouth, all of them for illusion of his brother he had on his mind.

"Vash" he can hear it as clear as the day, even when it's only a fantasy "Vash" his voice, —

immature yet masculine. His eyes narrowed while he looks at him from above. Almost as tall as him even when he's only 15. "Vash!"

Vash startles and falls out of his fantasy. That yell wasn't his imagination. It was—

He gest petrified.

Nai.

He...

"Oh, fuck!" Vash shouts,—

dildo still in him, while he pulls the covers on. Nai is in front of his bed, dressed in his pyjamas and gaze curious. Vash can feel his face getting red.

"Shit, Nai! What're you doing here? You should be asleep!"

Nai bites his lips and swallows. He looks at Vash longly, which—

makes Vash blush even harder.

"You woke me up with the kiss" Nai says, as if he hasn't walked on his big brother just jerking off "You were calling my name, so I thought you needed me".

Vash pales. Had he? Had he been calling for Nai? That loud?

He presses his legs together,—

feeling the toy swell up in him.

"I see... I'm so sorry, Nai. I didn't mean to disturb you. Can... Can you get out, now?" He asks as gentle as possible. After all, his baby brother has no clue that what he's done by entering Vash's room is so wrong. Nai's only a kid. It's not—

his fault—

"Why should I, when it's clear that you want me here?"

"Excuse me?"

Nai approached the bed, eyes on Vash, similar to a tiger.

"Do you really think I don't know what you were doing? Of who you were thinking?"

Vash's face gets even hotter. His heart is beating so—

fast it's almost all he can hear.

"What...?"

"You want me" Nai says simply.

"Huh? No, not at —"

Vash gets interrupted by Nai's scoff. "Don't lie to me, big brother. I know what you've been doing for months now. Did you really think you'd be able to hide it from me?"

What?—

No. It's impossible. It can't be. Nai surely doesn't know about it. It's impossible, it's not possible—

Nai pulls off the covers, leaving Vash completely bare. He cries while he tries to cover himself. Nai only smiles.

"You want me, brother. And I want you. Why don't we just—

stop pretending and unite, then?"

This can't be happening. It must be a dream. Or a nightmare. Vash isn't sure.

"Nai, no. You're just a child you don't know what you're saying!"

"Oh, but I know, dear brother. I know I desire you as well as you desire me. So, please, do not—

resist"

And just like that, Nai kisses him. Sweet at first, agressive and powerful the more seconds go by. Vash can't decide whether he likes it or not, and it makes him so angry. He geta furious at himself when he doesn't do anything to stop Nai. He's stronger than him, taller—

And still, he isn't doing anything.

Why?

Why?

When Nai slips his tongue inside of Vash, it stops having importance. He already knows why. Bc he's a sick freak who won't open his legs for anyone except his baby brother.

Shit.

Vash grabs Nai by the neck and makes him fall—

into bed with him. He gets on top of him, dildo slipping out and falling onto Nai's lap. Vash kisses him again, fully force this time.

"Ok, darling" Vash whispers "Let's see if you can make your big brother cum"
