We almost got caught by my dad last time we were fucking in my room, so this time we are trying to be a little bit more discreet. I meet my stepmom in her room for a secret fuck sesh. She looks so damned sexy in her red lingerie that she wants to show off some more. She models for me and I get harder than Abe Lincolns face on Mount Rushmore. Pretty soon I am flat on my back in bed and she is riding me again. She thinks I have been such a good boy that she does not even mind when I cum right in her pussy. I wonder what dad will think!
