A creepy man wearing a balaclava suddenly appears in the room of married Mio Mio. He predicts the date of her period and rapes the terrified Mio, pouring his sperm into her. The man appears again and again, filming her and repeatedly playing with her as she is unable to resist. This creampie hell doesn't end until she becomes pregnant, with the goal of insemination rather than pleasure. Mio's body is forced to accept the overwhelming fear and unwanted pleasure, and eventually... The brutal eroticism of a married woman impregnated with the child of a man she cannot see!
