A stranger jerked my dick on the train.

On the train, when everyone was busy doing their own thing, a stranger suddenly started masturbating my cock. She did it so passionately and skillfully that I couldn't contain my moans of pleasure. Her hand was so gentle and deft that I was on the verge of orgasm. It was so arousing and forbidden that I couldn't help myself and cum right there on the train under her skillful touch. It was one of the most unforgettable moments of my life that I will never forget.
