The narrator tells us that he's been having sex with a girl he just met. It's not from him, but from his senior, who warned him to be careful with the girl. The narrator says that if he were a pervert, he'd end up with a terrible ex instead of a good one. He's also worried that the girl's skin is so tight that he can't squeeze her. He wonders if most men like this. He asks the girl if she's okay with the way the man is acting. The girl says no, but the man's tongue is rough. He says he'll slap the man if he puts it in his mouth. Then he slaps the man who just met him. The man slaps him, and the narrator slaps back. He thinks that men are too naive to slap. He slaps a man who's moving his hips on his own, and then slaps an old man who he just just met .
