A store clerk plays a prank on a mother and daughter who are shopping together! The kind mother is in the store choosing clothes for her daughter, but the daughter can't refuse the clerk and keeps her voice low through the curtain. When the daughter tries to show her mother the clothes she chose, she witnesses her mother's sudden transformation into a woman and gets wet herself. Both mother and daughter start to writhe in agony, and we even find a brave girl staring lovingly at the clerk's dick!
