Rin has a comfortable married life with a kind, decent husband. There was only one thing she wasn't happy about: living with her crude, tactless father-in-law. Harassment was a daily occurrence and she'd had enough of it. Then one day, with her husband out, the father-in-law finds Rin asleep. Taking advantage of his son's absence, he quietly pulls her underwear aside, devours a sex that smells of sweat and female, drives his cock in and creampies her without mercy. From then on he keeps finding openings to attack, and her young body keeps getting used.
