He's so close. God. Kaiba's jaw is aching, his eyes are flickering, but he closes them so he doesn't have to let Mokuba know what kind of state he's in. As if his brother couldn't see the way his fangs settle just below his lip.

As if he was stupid.

Seto knows Mokuba isn't stupid. But they have trust between them, and that trust is what gets Mokuba to leave, if not far.

And once he's out of the room, Kaiba immediately closes the distance between himself and Yuugi.

"You...you're infuriating," he mutters, snatching one of Yuugi's arms up. The same he'd used before. And the same one he'd use again. "You're going to end up having a heart attack if you stay close to me.

You're making your problems my problems, Mutou."

Yuugi's wrist feels...heated, almost. His veins seem to stand out stark against his skin, a temptation that Kaiba could, at this point, resist. But resisting is still painful, and Yuugi's suffering a very clear hypertensive episode.

There's a simple way to fix that. An effective, if unorthodox method.

"I'm going to bite you. Do not, and I cannot stress this enough, keep making it weird. I don't want you to do what I tell you like some puppet!"

Hey, so. He notices when you do that, Yuugi. And he doesn't like it, which might be surprising. But he doesn't want some waif melting in his grip, just because he was a vampire! Just because...what, he had some compulsion built into him that Yuugi wanted to follow?

Fuck that. Stop that shit. He can't turn it off since he doesn't know how he's doing it, so resist it or something!

"Pretend you have agency, just this once, won't you?"
