An unsatisfied young wife indulges in creampie sex with her father-in-law, who has a penis bigger than her husband. Kuroki Ayumu
My husband is working alone, leaving his father-in-law at home. Naturally, I am not satisfied, and I fill my loneliness with masturbation. One day, his father-in-law witnesses Omu's appearance. The unfaithful father-in-law feels pity for such a wife and forces her to have sex with him, saying he will satisfy her. Omu resists, but her guilt towards her husband gradually disappears, and she begins to seek out his father-in-law for the pleasure she cannot get from her husband.
