A woman's skirt gets pushed up in the crowd on a crowded train. When she realizes it, her butt is completely exposed, and while trying to endure the embarrassment, she asks the man next to her to "please pull down your skirt"... The man, who was helping out in good faith, also gets close to the woman in the crowd, and unable to pull her skirt back down, he gets excited as he touches her butt, and taking advantage of the woman's immobility, he sticks his hand inside her panties...
