My friend allows me to fuck his wife while he records and touches himself

My friend is a very jealous man and takes very good care of his wife. That’s why when he asked me, while standing next to his wife in the same house, that I should jerk off in front of him so he could record a type of porn scene, I was completely surprised. How is it possible that my friend wants to jerk off his wife when just a few days ago he was beating up a guy on the street because he saw him talking to her? Obviously, I had my doubts, but they both convinced me and I agreed. He wanted me to make love to her, not treat her badly for that reason, so we began kissing passionately and then he goes down on me with his sweet mouth, erotically and provocatively devouring my dick. I eat her pussy after that, and after touching her vagina with my fingers, she positions me above her with my black dick and she begins to go up and down, moving to penetrate her pussy with the help of my thick member. For a moment, I give her another rich and deep licking, just as good as the first one, and I lay her down on the bed to give her a really good fuck.
