Fuck yea I would.
Levi, naked, kneeling in front of Eren as he pulls his cock out of his pants. It's so big he has to use two hands, and even then he can only properly suck the tip from his angle. Wrapping his lips around the leaking head as he hums in satisfaction. He kisses up and down the length wetly, unable to stop himself from grinding his own erection against Eren's foot between his legs. He licks up the streams of pre that dribble down Eren's cock hungrily, slurping over the crown as he rubs his tongue over the slit, seeking more. Sucking up every drops as it oozes out.
