His Father's Warmth

Nagama Mika visits boyfriend Satou Mikio's home and meets his father, who at dinner thanks her for dating his unsuccessful son. Mika has never orgasmed from sex with Mikio. The next day, while Mikio is out, the father interrupts her studying, claims he saw them having sex, and offers to practice in his son's place; aroused by the father's large penis, Mika—wearing cat-ear accessories—engages in fingering, oral sex, penetration, and creampies as he says he will impregnate her. Mikio returns, smells mixed body fluids, and finds them mid-act; the father forces Mika to say whose penis is better, she answers that the father's feels far better, and he continues penetrating and creampieing her while she climaxes and talks about being impregnated. After ejaculation she says his penis was dangerously good and she almost died of pleasure; when Mikio returns she greets him still nude and dripping in cat ears, saying she will have a child with both of them and asking the father to impregnate her thoroughly next time.
