JUC-519 Young Mother-In-Law's Secret Sexual Education Rin Aoki

Rin married Sentaro and became the mother-in-law of Manji, the child of Sentaro and his ex-wife at a young age. Manji grew up with his father telling him all about studying since he was little, and he had no knowledge about sex and didn't even know about masturbation. Because of that, Manji gets his panties dirty with wet dreams almost every day, and Rin feels responsible as a mother. .” He told me about the body and sex of women.
