SNIS-544 Since The Day I Discovered My G-Spot… Aya Sakurai

Aya, a female doctor who is a surgeon at a certain private hospital in Tokyo. She is made a subject of a human experiment because she flatly rejects her colleague Dr. Mori, who asks her to have a physical relationship with her only because of her sexual desires. What is the secret experiment in the hospital? “I’ve increased the sensitivity of Mr. Sakurai’s portio hundreds of times with the newly developed unlicensed drug.”
