A young couple on a crowded bus. The wife, who is sexually frustrated, can't stop getting excited by the body of a man other than her husband who is pressing against her. She presses her ass against the other man and wiggles it so that her husband doesn't find out, and the cock that immediately becomes erect becomes even more exciting. She tastes the cock that is sticking out of his pants with her ass, grabs it tightly, and leads it to her wet crotch and does it on the spot.
