Naked mother decided to cheat with her adult stepson

In relation to my father, I act disgustingly, but in relation to my stepmother - I am the most faithful lover who is always there. He ran into his stepmothers bedroom and fucked her while she was talking to her father on the phone and did not stop until she asked. This is how we live in a crazy love triangle and there is no jealousy from the word at all. Only constant sex with an experienced woman and of course pocket money.
