A Russian stepmother is the best tutor... she'll show you where the vagina is and where the clitoris is.

A Russian mother with a beautiful body asked her stepson what he had been doing since morning, and it turned out that he was preparing for an exam on the structure of female reproductive organs. It's a difficult subject... for a guy who has never had a girlfriend, so his stepmother decides to help him. After taking a bath, she comes to her stepson and spreads her legs. The shocked guy studies his stepmother's pussy from top to bottom, and then tests it with his dick.
