[Sokuochi Shoujo (Kagamino Mochiko)] TS Siblings

A newly transformed Kazuki gets paraded in front of the mirror by his gleeful little sister, who insists her big brother was always meant to wear girl clothes—and his racing heart suggests she might be right. Stripped of his old identity at school and no longer seen as a man by his crush Reina, he's scooped up by a pack of bold gyaru girls who promise to 'teach you all sorts of things,' making surrender feel easier than resistance. Their karaoke hangout soon becomes a hands-on lesson, with Kazuki pinned under eager mouths and wandering fingers until she's left cumming, dazed, and seeing white.
