外見も性格もまんま男なボクっ娘「僕が男じゃないって言うなら君が教えてよ、僕がオンナってこと」岸谷燈

Tō is a tomboyish and serious swimming club captain. The male members, fed up with her seriousness, gang-rape her by force. When Tō is down, saying 'I'm the same as the other guys, right?', her best friend steels herself and tells her, '...Tō, you're a girl after all,' trying to set her straight as a normal girl. Tō hesitates but accepts her friend's suggestion, saying, 'If you say I'm a girl, then you teach me.' Eventually, Tō's face shifts to a feminine expression, and she arches her sensitive body, writhing in ecstasy and cumming like crazy from a woman's pleasure!!
