My wife fucked my friend's penis on the sitting video

I had given my wife free time to have sex with her friend. So now she used to bring her friend home and have sex. When I came home from office, she would be seen riding on her friend's penis. Then I would sit comfortably in the chair and enjoy his sex. My wife would hold the friend's penis and set it in her pussy and then sit on it. Both of them would have had sex, completely ignoring me.
