I have a friend who always comes here at home, just to my stepmother

My best friend ended up becoming my stepmother's lover and I can't do anything at all, because I feel tremendously jealous of him for going to bed with her almost daily when my old man is not there. He shamelessly arrives at my house, greeting me and my naughty stepmother is already waiting for him on all fours and all naked on the bed to give him her pussy all afternoon while I stay there in the living room listening to all the moans of pleasure she lets out while being devoured by him.
