SSIS-510 My husband's parents' house arrived a day early. One night in the absence of her husband, Saki Okuda was raped by her father-in-law whose sexual desire went out of control and became a prisoner of his pleasure.

This summer, I decided to visit my husband's parents' house, but he was going to be late one day due to work. My husband's parents' home without a husband. My father-in-law lost his partner last year and lives alone. Until then, I thought he was a kind father-in-law. My father-in-law lost his mind due to loneliness and increased sexual desire and attacked me. Although she resists, she is no match for the man's strength and is raped. However, she is excited about having sex with a man other than her husband.
