In Minami Haru’s first groping-themed feature, the exhausted K-cup office lady catches another crowded last train after overtime and a business dinner. A nearby man accidentally brushes her swaying breasts, and when she is too drunk and tired to react, he mistakes her silence for ignorance and escalates. He squeezes her enormous tits with both hands and keeps fondling her until the unfamiliar stimulation makes her climax from breast play, gradually leaving her addicted to his technique.
