In order to acquire laundry supplies, Penny Barber goes into the bedroom that her stepsisters, Jill Kassidy and Liz Jordan, share with one another. Penny is shocked to discover a strap-on dildo in the space. In a fit of rage, Penny approaches the two females and asks which one is the owner of the sex toy. However, neither female acknowledges that they are the strap-on's owner, and they also decline to turn on one another. Penny threatens to spank BOTH of them if she doesn't receive a response. The females tell her to go ahead and bring it on, defiantly promising never to snitch! Although Penny gives Liz and Jill a spanking, they seem to like it and taunt her to perform better. The two girls continue to tease Penny as she puts on the strap-on and fucks them. It becomes obvious that the girls are enjoying everything Penny does to them... but then again, it's pretty clear that Penny is enjoying it too!
