A newly formed family after remarriage. The stepfather and his stepson get along well, and everything seems happy... Until the lustful perverted stepfather can't control himself around the voluptuous ass of his stepson J● Rin. He drugs her and starts training her as his personal creampie hole, fucking her however much he wants while she's unconscious. Night after night of wild sex, deep dicking, anal play, and even letting him cum inside her without pulling out. Eventually, Rin loses all sense of reason and begins riding her stepfather like a cowgirl, shaking that huge ass and taking every inch of his cock. She becomes a sexual monster, completely consumed by her desires and willing to do anything to satisfy them.
