On a crowded Tokyo train, a busty Japanese beauty in a low-cut blouse attracts the lecherous attention of a chikan, or groper. He discreetly moves behind her, his hands finding their way to her full, ripe breasts, squeezing and kneading them through her thin blouse. She squirms, trying to maintain her composure, but her nipples harden against his touch. The chikan's hands roam, caressing her curves, making her wet and breathless.
