SNIS-544: Since the Day the Portio Was Developed... Aya Sakurai

About this work

Aya is a female surgeon working at a private hospital in Tokyo. After she flatly rejects her colleague Dr. Mori, who seeks a physical relationship driven only by sexual desire, she is made the subject of a human experiment. The experiment, secretly conducted inside the hospital, was... “We used a newly developed, unapproved drug to boost Dr. Sakurai’s portio sensitivity by hundreds of times.” The aching sensation deep in her womb became unstoppable for Aya... The woman gradually becomes a slave to portio sensation.
