University student Takane is living a depressing life because he has been labeled as a manwhore who makes moves on both men and women alike because of his good looks. One day, at a welcome party for new students, he is fed up with a guy asking him out. Irritated, he brushes him away, only to witness the guy take a new student, Minami, into the restroom right after. He rushes after them and, as suspected, saves Minami from being assaulted. Minami says he will suck him off as a thank-you and forcefully takes Takane into his mouth, but he's so bad at it, Takane can't cum at all! However, Minami is visually very much his type, and he is unable to resist his request to make him as a sex friend, so their physical relationship begins—!?
