A woman whose skirt slips up and her big butt is exposed in a situation where she can't move on a crowded train. Realizing that she can't put her skirt back on her own, she asks the man beside her to lower her skirt, but... A man who is excited by his embarrassed face and bare ass reaches out to his buttocks and even touches her pussy. The embarrassing feeling of a woman who is touched by a man without being able to move will eventually turn into excitement.
