SGKI-101 Will the boys find out? The flat-chested sisters’ role-play health check — they tried to endure even when their sensitive spots were touched, but in the end they were overwhelmed and brought to tears, complete edition

Competing for the spotlight in their troupe, the flat-chested twin sisters Yuna and Hinano disguise themselves as boys and infiltrate an all-boys school by surprise. What awaits them are tense situations like changing clothes in the classroom, a nerve-racking health check with a hidden device, and being questioned about the slight swell of their chests, which they insist is just muscle. But their bodies can’t lie, and their true identities are quickly exposed to the male students, putting them in a desperate situation. They face one challenge after another, including urinal use and demands to undress. Overwhelmed by intense pressure, they are driven to tears by the sensations. What fate awaits the two, for whom exposure means the end? I’m a man, so I won’t give in!
