JUQ-533 Subtitle Indonesia In-Laws' Sex Education Addiction - Rio Kuriyama

Rio, a young wife, lives with her husband (Jun) and her retired father-in-law. Initially, Rio was the ideal son-in-law, but over time, he became lazy about housework and often wandered off. His suspicious mother-in-law eventually followed Rio and caught him meeting with a man (her former boss). Using this "infidelity" as a weapon, his mother-in-law threatened to report Rio to Jun. A terrified Rio was forced to comply with his mother-in-law's every command under the pretext of "education" to become a good son-in-law. At first, Rio vehemently refused and felt disgusted. However, his mother-in-law continued to force him to do humiliating and degrading things, from licking his sweaty body to satisfying his sexual desires. Slowly but surely, Rio's defenses crumbled. He, initially resisting, eventually came to enjoy his mother-in-law's rough treatment and dominance. By the end of the story, Rio had completely transformed into a "perverted son-in-law" addicted to his mother-in-law's "education," even begging to be impregnated. This illicit relationship under one roof continued without the husband's knowledge.
