Introducing the beautiful and busty G-cup Nao Mizuki. One day, Nao discovers her son looking at pornographic magazines. When she tries to scold him, she finds out that her son is actually looking at pornographic magazines instead of female nude models to study art. She suggests that she act as a model, but the beautiful mother ends up getting her pussy wet in front of her son. Her son is curious and plays with her pussy, causing her to drip with love juice... a forbidden erotic experience that she unintentionally feels for her son during the process of sex education.
