[Wasabi (Honjou Tatami)] I Became A Man And My Onee-chan Became A Woman [Full Color] [The People With No Name]

A body-altering twist turns the narrator into a young boy and leaves his curvy cousin more woman than he can handle. Bent over and taking him from behind, she comes undone completely—eyes rolling into hearts, mind blank, gasping about the warmth flooding her belly—while he shyly confesses how happy it makes him to be inside her. But passion outruns preparation fast, and a midnight convenience store run for more protection becomes the most urgent errand of their lives.
