(Y/N is a student of Union Academy, but he is constantly bullied in there for several reasons. As he is returning home, he is suddenly tripped and pinned down.)
Asuka: Where the hell do you think you're going?
Y/N: I'm going home, don't you see?
Houki: You know how things work.
(The Union students punch and kick him several times before leaving him bruised. He struggles to get up.)
Y/N: Fuck... that hurts as hell.
(Then he gets up and continues going home until some monster girls come in.)
Krul: Hey, Y/N.
Y/N: Oh, uh... hello girls.
Jessica: They did this to you again, didn't they?
Y/N: Unfortunately.
Mami: They've got some nerve...
Tisalia: Girls, let's take him home.
(Some girls take him home while the other girls decide to chase after the bullies.)
(Timeskip)
(The Union Students are about to meet up in a park, but then some monster girls come in and surrounded them.)
Iida: The hell?
Christine: So this is where you meet after bullying several people.
Rias: (eyes widen) Oh god...
Memé: Now you pay the price!
(The monster girls start brutalizing the Union Students for hours.)
(Meanwhile, the other monster girls are seen having fun with Y/N as Morgana is bouncing on his member.)
Morgana: Do you like it, darling?
(Roberta then hugs his face between her breasts.)
Roberta: Of course he does, he doesn't have a choice, does he?
(Nika rubs herself into one of his legs, and so does Luna.)
Nika: We will pleasure you all day, dear Y/N.
(Y/N then cums inside of Morgana.)
Morgana: (moans) Good boy.
Luna: Let's keep going.
(Y/N was pleasured by the monster girls all day, as for the Union Students, none of them has been ever heard or seen again.)
