Eren makes a sound that's almost a protest when Jean moves his foot away. He gets a handle on that before it's too embarrassing but that's all he has time to get a handle on at all.

Jean's knee hits his face and that sound is all pain. He's not sure if his nose is actually broken, but it doesn't matter. Blood gushes down his face. He can taste it, familiar in his mouth. The world might go sideways if Jean wasn't still holding him.

Here. Now. Pain.

He glares up at Jean, open-mouthed, blood streaming down his face. He can heal that any time he wants. He's purposefully letting it go, ruining his clothes, bleeding onto the top of Jean's boot because he's close enough.

His hands are still tight in Jean's and he wars with himself about how and whether to fight back.

Jean's boot on his dick isn't a deterrent. He'll fight if he decides do and pay for it if that's how it goes.

He's not worried about pain but he worries a little about denial. After all this, he's rock hard, desire and the haze of pain and blood working over his need to be as big of a pain in the ass as possible.

"...okay," he says, which doesn't mean much. Eren's agreement isn't worth shit; he can change his mind at any second without warning.

For now, he opens his mouth again, wider, still bloody, obscene. He'll participate but he wants Jean to put his cock back in his mouth first. Who is complicit in what here? Eren's still bleeding on purpose just to be disgusting.
