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