Jean isn't rushing him just yet. Eren's doing what he asked after all, and even if he's slow about it, it feels good. Jean could stand in stoic silence for this but that's not the kind of person he is.
Instead, he hisses under his breath, letting his hips rock forward when Eren bobs his head down, helping him go just a bit further into his mouth.
"Fuck, you look good like that." That being covered in blood and a little bit of spit, running his tongue on the underside of Jean's cock as he sucks at it. He lets go of one hand, shifting Eren's hands together so he can grasp both wrists in one of his own. It means he's not pulled back quite so far, but whatever.
With his now-free hand, he presses his thumb against the bridge of Eren's nose. Then he swipes down, through some of the blood on his upper lip, and drags it across Eren's cheek, a tacky smudge. He presses his thumb against skin, until he can feel the drag of his cock in Eren's mouth through the flesh.
"it's also just a side effect of eren"
