Come to mother-in-law

When I come into the living room with the laundry basket, my stepdaughter's guy is sitting on the couch. Alone. He sent her shopping. Since I'm completely under-fucked again and he certainly won't be sufficiently satisfied by the spoiled brat, I seize the opportunity and feel him out. It quickly becomes clear that I was right and that he wants more sexually. It's not a problem at all... Let the mother-in-law do it. Nobody needs to know.
