SNIS-511: Since 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 her out of corrupt intent, she was made the subject of a human experiment. The experiment, secretly carried out within the hospital, was this: “We approach the cervix — the so‑called portio, where women feel the greatest pleasure — with drugs and electrical currents.” A throbbing sensation awakens from the deepest part of the uterus... and the woman becomes enslaved by the portio sensation.
