When I cum into the living room with the laundry basket, my stepdaughter's guy is sitting on the couch. Alone. He has sent her shopping. As I am once again completely underfucked and he is certainly not sufficiently satisfied by the spoilt brat, I take the opportunity to feel him out. It quickly becomes clear that I was right and that he wants more sexually. It's no problem at all... Let the mother-in-law do it. No one has to know.
The second part, in which the stepdaughter would have caught us, can be found at @HollyBanks ("You pig fucked my stepmother!?!").
