This series is a series of lewd acts on super crowded trains where you can't even move. People's hands and bodies are pressed against their buttocks and chests without knowing whether it's a trick or a coincidence in a crowded state. Furthermore, since the season is summer, the sweat of each other is mixed and the discomfort index is pushed in a sudden rise. Even if I notice it, I can't dodge it, and my pants are soaked with sweat and man juice.
