Levi takes Eren's cheeks in her (his?) hands and draws him closely. Their eyes meet and a blush consumes Eren's face while a light pink dust Levi's cheeks. "You are LOUD and MESSY and ABNORMAL and I like the way you punch Military Police bitches in the face." Levi nearly shouts, as if he's (she's?) been holding this in for an eternity. "I know I'm an asshole and you're the only person who understands what I'm really trying to say so I feel okay being my asshole self around you. Also, your eyes are HORRIBLE because they make me feel like I'm having a stroke whenever I look into them, but.... in a good way. What I'm saying is, be my shitty boyfriend if you want." Eren smiled ear to ear as he pressed his lips tenderly to Levi's. At that moment Levi became a man again. His curves disappeared and so did his breast, but his firm, round butt stayed the same. His soft features became hard in Eren's hands as Eren ran his fingers through Levi's undercut. Their lips gently parted and when Eren opened his eyes he realized the change Levi had gone through. Captain is a man again. That didn't change Eren's feeling for him though. Sure people would judge and stare and mock them, but none of that matters when you're truly in love.
I know this wasn't really a joke, but I love Ereri too much to not have done this. (^w^)
