I fuck a therapist while she sucks my wife's tits

My wife and I wanted to save our marriage, so we visited a therapist. While we were at the therapist's office, she started fondling my wife's tits. The therapist suggested we have a threesome. I then fucked the therapist from behind while she sucked my wife's tits. The therapist and my wife also took turns sucking my cock and licking each other's pussy.
