Cum on ass
After returning home, Bill notices that Amy, the best friend of his younger sister, is primping and preening in front of the mirror. She is pulling her new fake breasts up, clutching them, and showing them off to herself, which is a clear sign that she is delighted and excited about them. Bill simply keeps silent while she does her little performance; he doesn't want to stop the show. When he eventually makes himself known to her, she is startled that he would invade her personal space. They get carried away in the bathroom, where he is only trying them out on himself!
