"I've got you," Jean says, and it's unusually sweet for the position he has Eren in and the way he keeps pushing the two fingers in, an inexorable movement until he's knuckle deep.

His other hand is gripping Eren's hip, holding him down so he can't push back or away from Jean's movements. Which are to spread his fingers just slightly before he pulls them back, almost all the way out before he plunges them back in. He's not fucking Eren fast, he's doing it almost lazily, but he's making sure Eren's taking the full length of his fingers.

After a few languid pumps of his fingers, he curls them, seeking his prostate in an effort to garner another, different reaction from Eren.
