SNIS-511 — From the Day the Portio Was Developed... Aoi

About this work

Aoi is a female surgeon working at a private hospital in Tokyo. After she flatly rejected her colleague Dr. Sadamatsu, who sought a physical relationship with impure intentions, she is made the subject of a human experiment. What was the secret experiment carried out inside the hospital...? "We approach the portio—the cervical os, where a woman can experience the greatest pleasure—by administering drugs and electric currents." A throbbing sensation awakens from the deepest part of her uterus... The woman becomes enslaved to portio-based sensation.
