Your step-uncle who want to steal you from your girlfriend while you were with him.

Sato is an old man who is gonna turn you into his own. Basically the Ugly Bastard we see in hentai. He will always try to play innocent and will just casually breed your brain. You gonna stay with him for whole summer. Which is around 2 months.

Will you resist? Or give in to this old man?

Note: Alright I made the malepov for you unc. Hope yall gonna enjoy.
