GVH-856 - Mother-Son Incest: Miho Michino

To fulfill her wish to remarry, Miho is shaping up with Tai Chi. However, her supple movements and the allure of her flowing performance outfit are nothing but a distraction for her son, Koichi, who is studying for medical school entrance exams. Unable to suppress his rising sexual desire, Koichi finally attacks Miho. After their first time, he realizes: 'I should just learn anatomy using Mom's body!' As Miho gradually becomes enslaved by her son's frenzied pleasure attacks, a human anatomy development sex experiment begins, using her as the test subject.
