"Fuck you," Jean bites, distracted enough by the heat of Eren around him that his quips are starting to get a little less sharp. The snap of his hips into Eren gets faster, and his gaze drops from Eren's face to look at where he's thrusting into him, making Eren stretch around his cock.

It makes him groan, a little, hair falling out of the slicked back style and into his face, curling a little. He hikes one of Eren's legs further up his arm, into the crook of his elbow, making him bend even further. With his hand freed, he reaches up to wrap it around the front of Eren's throat, squeezing.

And because he's a gentleman, he shifts his hips a little, trying to brush over Eren's prostate so it's not just the stretch that's making Eren groan.
