TW for incest and dub con (kinda... it's just Knives being manipulative)

Random idea I had on a Monday morning when talking w Meredith lets GOOO

the director gives Vash a script where he will be fucked by his twin brother. Theyre hired a guy that looks like him, but he's a top and they'll use makeup to fix him up even more to look similar to Vash
Thats why the concept came to be, for a twincest porn vid

Nai agrees to the script, even suggests a few tweaks, and makes an agreement with the director for some improv during the filming
so when the day comes and Vash is on set, all prepared and prettied up, his eyes practically fall out of his head when he sees Nai walk on set..

Nai's so broad and muscular and mouth-wateringly hot and he knows he's not gonna have any trouble getting it up today 😳
Nai has to try and keep calm bc the moment he's waited for is finally here, but he manages a cool smile as he approaches Vash and holds out his hand.

"Vash, it's a pleasure to finally meet you, I'm Millions Knives." and Vash gulps, skin already feeling hot, but he smiles back. "It's nice to meet you too, Knives."'

Nai decides to start working his charms right away, looking Vash up and down with a smirk, "You're even more beautiful in person." And Vash's heart races, but he lets out a little laugh and says, "Thank you! Oh, they even added a beauty mark on you to mirror mine!"

One of the makeup artists was standing right beside Knives and she tenses as she looks at them. She didn't even notice that. No, the mark wasn't added, it was already there...
But Nai just laughs. "Such close attention to detail. It's like we're two halves meant to be a whole."

A little more chitchat passes between them and then its time to start filming. Vash looks over the script one more time, refreshing himself on his lines, and is silently impressed that Nai insists that he has it memorized.

He must be really experienced with acting, Vash thinks, and takes a deep breath to try and relax. it's always nerve wracking to film with someone new on the first day, but he tries to tell himself not to worry so much and just act natural, thats what produces the best results

"Vash, it's been so long," Nai starts, approaching Vash with such intense reverence that Vash is immediately caught within the scene. He struggles to focus on his upcoming line as Nai towers in front of him, reaching out to cup the side of his face. "My precious little brother.."

"I haven't seen you in forever."
and the truth is, all of Nai's lines are rolling off his tongue so naturally that Vash is starting to forget about the cameras focusing on them, the microphones bobbing near their heads, the shuffling of staff as they keep the lighting perfect

The way Nai caresses him, so gentle, like he's truly enchanted-- and then his grip firms up as he insists on showing Vash just how much he missed him. How "no one would ever understand your body better than me, Vash, your own brother--let me prove it to you"

before Vash knows it he's being pushed down on the bed and his pulse is pounding, he's hot all over, and he's embarrassed to already be hard. Nai is just so strong, so big-- his voice is so low and husky, and Vash can hardly wait to hear him moaning as he pushes inside of Vash

And then Nai claims his prize, kissing Vash with so much hunger that Vash melts into it immediately. He almost submits, but then he recalls the script, how he's supposed to resist a little, play up the whole tabboo factor of it all. But it feels so right that Vash almost forgets

Reluctantly, Vash shivers and breaks the kiss, turning his face away. "T-This is wrong, we're brothers...! we can't be kissing like this..."
Vaguely, Vash has a memory of his foster mother running her hands through his hair when he was 10 or so.

He remembers when she told him about his twin brother--yes, he has one, but they were separated a few years ago. Vash can barely remember him, but he does feel some sort of weird loss in his life when he thinks about this mysterious twin.

someone just like him out there, living a separate life. Vash never tried to find him, but sometimes, he remembers that the twin exists..

What was his name again...? He swore Rem told him once...

Nai pushes him down firmer, harder, demanding more. "Vash, relax, who needs to know? If we both want this... no one can stop us, can they?"

Vash gasps as one of Nai's hands presses between his thighs, grinding sweet friction down onto the bulge in his pants, forcing him to remember how hard he is.

Vash trembles because it feels so good - he tosses his head back and whines when Nai bites down onto his neck, taking advantage of Vash's submission
What was his name...? Vash thinks again.

He really shouldnt be thinking about his actual twin brother while he's on set about to be fucked by his imaginary twin, but for some reason, the name is on the tip of his tongue and he can't stop thinking about it.

Maybe it's just heightening the taboo nature of it all. Vash knows more than anyone how unreasonable kinks and fetishes are...
He's undressed, his legs are spread, and Nai is kissing down his body, teasing and biting and licking

His eyes are smouldering, not once looking away from Vash as he tears him apart. Nai is so intense that Vash truly is forgetting all about the fact that theyre filming. He's so hard, his heart is racing--

Nai is just completely devouring him, hands and mouth roaming everywhere, making Vash feel twice as small as he really is.
Nai sucks on his cock, eats him out, fingers him roughly, scissoring him and opening him up--Vash is prepared, but he trembles and claws at the sheets.

Vash whimpers every now and then that this isn't right, that they need to stop-- but Nai every time just chuckles and continues to take, take, *take* what is his.
Nai crouches over him, lips close to the shell of Vash's ear, as he's lining his cock up along Vash's twitching hole.

And that's when he growls, "Remember me yet, Vash?

Vash feels his heart drop. It can't be. He can't be right about this strange intuition. It's impossible, it's so wrong, and yet--

Nai shoves himself inside, bottoming out immediately, and knocks the truth right out of Vash before his brain can even catch up.

"Nai...!"

Nai-- his twin brother. Nai is his brother. Oh my god, Knives is Nai-- and Vash can't do anything about it. He gasps, he came so fast from the realization, stars swimming in his vision as Nai fucks him roughly right from the start.

He doesnt even give Vash the chance to reach that post-nut clarity (LOL) he just keeps pounding him, forcing Vash back into hardness
Vash loses track of how many times he cums. It just keeps happening.

It's so intense now with the knowledge that this man is actually his twin and that they really shouldnt be doing this at all. and yet... Vash keeps getting hard, keeps cumming. Is he awful for this?? Shouldnt they stop??
but Vash doesnt want it to stop..

Vash is too stunned to speak after filming. Staff's used to it, Vash is usually too exhausted to converse, they get him food, water, clothes, all he needs to adjust back to normalcy. But Vash is truly speechless. He's torn between staring at Nai and avoiding his gaze at all costs

When he's left alone in his changing room, Nai comes by, entering without even knocking. Vash turns to face him, a bit scared, still turned on.

"You knew," Vash says, his throat tight. "You knew the whole time."

Nai smirks. "I've missed you so much. How else could I show you exactly what I meant by that?"

Of course Vash is upset-- "This is sick, Nai! You know that! How could you-"

"Don't play moral high ground now," Nai interrupts him, coming closer, towering over Vash again and forcing Vash to look up, to realize that even though theyre twins, Nai is somehow so much taller than him. He's grinning as he runs his thumb along Vash's lower lip.

"When you finally pieced it together, remember what happened, Vash?" He leans in close, words brushign on Vash's ear as he whispers, "You came. Hard."

when Nai pulls back, Vash is frozen in place, bright red up to his ears.

He's so ashamed. but he can't deny what Nai jsut said and he feels like no matter what he says, he will sound pathetic.

Nai slides his fingers along the side of Vash's neck, right over where his bite marks still rest, throbbing.

"Be a good boy for me, Vash, until next time."

When he leaves, Vash hides his face in his hands with misery.

how can he reason how hard he is, again, after all of that...?
