Every morning, I commute to school on a packed train for an hour each way. Surrounded by middle-aged men and the overwhelming smell of sweat, every morning was unbearable. However, one day everything changed—amidst the crowd, I ended up pressed against a classmate I barely talked to, Kawakami-san. Due to the train's movement, I accidentally touched her soft buttocks, causing an instant erection that she noticed. Bracing for social death, what Kawakami-san said was… "You can come inside me"…!!? What?! From that day on, my days of being allowed to ejaculate inside her both on the packed train and after getting off began.
