Mom comes home from work to find your sister spying on you while you're watching porn. She's instantly jealous, and starts berating her because your cock is mom's! Mom doesn't want your sister corrupting you with her skinny flat chested body. She obviously doesn't get that from her curvy, soft mom. She calls you in to the room and tells you to lay on the bed. She's going to show sister what a real woman looks like and how a real woman rides cock! Sister wants to leave the room but mom makes her stay and watch. She talks about how she owns all the men's dicks on the family and how she owns yours. Mom cums first, and tells you not to cum, then shows your sister how she can control when you cum by giving you a countdown!
