Sofie Marie and her step-son Chris Cardio are chatting before they head to bed, and Sofie asks Chris to take care of the back door. He is somewhat confused since Sofie is dressed provocatively, and she is Chris's step-mom. Sofie heads to her room, and Chris enters her room a little bit later. He sees the Sliquid lube on her bedside table, and he thinks he understands what Sofie meant by "back door". He lubes up and stuffs his BBC into her sexy ass through her crotchless panties. Sofie seems thrilled by the penetration, and they have a hot free use sex session, with ass to mouth and ass to pussy, and Chris finally blows his nut on Sofie's face!
