The years of being a student often bring the most wonderful memories in the classroom. The schoolboy in the movie is the same, but the difference is that this memorable moment takes place at a friend's house with his mother, not in the classroom. Arisawa is a young, lascivious mother who, despite having a husband, seems still unsatisfied with this ambitious woman. Her son's friend coming over is a fantastic opportunity for her, as she continuously unleashes tricks to seduce the inexperienced young boy, while he naively waits for the moment when his friend isn't paying attention to start daringly reciprocating. The movie doesn't stop there; there are two more parts with beautiful actresses playing roles, but generally, the content is quite similar to the first part.
