Jean lets him shove off, for now, doesn't drop him like he could. Eren's decided now is his chance to mouth off. Jean isn't even really annoyed by it; he's more considering what the best punishment might be.

He moves his boot away from under Eren, shifts his body back a little bit so his cock is away from Eren's face. He looks down, still considering, still holding Eren's arms up. Then he jerks his knee up, smashing it hard into Eren's nose. There's not any room for Eren to sway away since Jean's got him by the hands.

He doesn't know if he just busts a vessel or breaks Eren's nose. Either way, it starts bleeding. He doesn't tuck his boot back under Eren - now, he presses his foot over his cock.

"Let me rephrase, then," he says dryly. "Fuck your mouth on my cock."
