[Rio Nagarekawa Lesbian Ban] Rio, a college student who applied for a female-only underwear monitor part-time job. On the day of the event, under the direction of Tsubasa, a manufacturer employee, I decided to wear a luxurious and obscene lingerie that I had never seen before. Rio is raped by exposing her racy underwear, and is called a comfort test and is sexually harassed. However, all nerves are stimulated by Tsubasa's obscene gestures, shame and impatience, and the body gradually becomes hot and sensitive.
