Three years into her stepfather's remarriage, Ichika is suddenly shocked by a drastic change. Within just three days of her mother leaving home, the trusted stepfather transforms completely. He slips her a drug, incapacitates her, and repeatedly rapes her while she sleeps, filling her with creampie after creampie. Drenched in endless waves of female ejaculation, she's forced into toy-induced orgasms and driven to desperate, pleading blowjobs that shatter her sanity. Fallen as a mere cumdump, Ichika has her pussy fully dominated, soaked in fluids as she repeatedly gushes. Her mature, voluptuous body driven mad by three nights and days of aphrodisiacs, Ichika is mocked by her stepfather as he laughs, "So this is the face you make when you actually feel something (lol)."
