In the popular chikan series, we focus on incidents involving only uniformed beautiful girls! Men and women are crammed together in a crowded train... The temperature inside the car rises, and bodies rub against each other whether they want to or not. The more distant a man is from women, the more his crotch swells, and lewd fantasies spread endlessly. The smell of sweat and women, and eventually the sweaty man's hand slowly moves into the pleated skirt... Using the train's sway, the fingers move millimeter by millimeter, and the crotches of the nine uniformed girls, trembling with shame, become wet and slippery!
