Aya Inami, a guinea pig who studied women's graduate school students

This is an obscene experiment conducted at the Sakai Graduate School. The target was Aya. Called an experiment in molecular biology, he was compelled by the professor to self-comfort and received a mere question of his first experience, initial tide, etc. It leads to sexual intercourse with an assistant, but it is for the sake of experimentation. Finally, the sex function has been revived and I have middle-aged sex with my professor. Aya that feels even though it is an experiment. It is a must-see for students who have beautiful bodies and looks.
