I suddenly remembered. This world is the world of an erotic manga, and that I was reincarnated as the scumbag who is supposed to steal the heroine in this world. Well, I don't have such a hobby, so I thought the heroine should get along with the protagonist. But why are you paying attention to me, heroine?

Adaptation of the popular Novel posted in Kakuyomu "The Story of a Man Who Is Reincarnated as the Shittiest Guy in a Doujin, but the Heroine Keeps on Coming Close to Him"

But at the same time, remembering that makes her feel somehow strange. Her fingers slip beneath her skirt as if by reflex and while thinking about getting assaulted by that disgusting man she pleasures herself against her better judgment while she is brought to climax in her fantasies!?
