HMN-816 | I transferred to an all-boys school and pretended to be a tomboy... but during swimming class, my nipples were hard and I was exposed as a girl in a flat-chested boy's swimsuit, and a virile classmate kneaded my sensitive nipples, turning me into a submissive slut and a cum receptacle... Kuramoto Sumire

Sumiaki transfers to a former all-boys school as a scholarship student. It seems he was welcomed with special treatment thanks to a connection between the chairman and Sumiaki's father, but he has a big secret: he's a girl. However, his despicable homeroom teacher and even the male students eventually find out he's a girl... "This guy gets turned on by his nipples like a girl lol... but he doesn't have a dick?!" He's overwhelmingly just a female after all...! His sensitive nipples are kneaded and he's completely defeated by the erect cocks of the virile boys!! In the end, he becomes a submissive female slut and gets cummed inside of... A total of 13 times!!
