I'm Being Fucked At Night By My Father-in-law, Whose Nightly Erection Is Too Great Every Night... Kazuka Hoshimiya

Ichika, living with her husband and father-in-law, couldn't stand her father-in-law's sullen personality. Because of that personality, his wife left him, and he was always erect with pent-up sexual desire. Ichika hated her father-in-law, but since her husband was somewhat ED, she found herself staring at her father-in-law's impressively erect member. Misinterpreting this as affection, the father-in-law plotted to calm his overly hard cock by raping his daughter-in-law at night. The unfaithful wife reached her climax through unwanted sex with her father-in-law's perfect erection, incomparable to her husband's.
