Every Saturday for a semester I would take an Adult course in Human Sexuality at the local Junior College. I'm married with kids but then again....
I would take this gal home after class and we would be sexed up. We would masturbate each other in my pickup, sometimes twice it was so good. It didn't stop there either.
One time her kid bro took me to school in his pickup cause my pickup broke down and she was unavailable. (In fact I was his regular ride for 6 weeks.) She dropped out because of work.
All he would talk about was jacking off, so we groped each other and then we opened our jeans and jacked off each other three times. I can tell you a guy mutual jackin' is different than a hand job from a gal. We were regular jack off buds for the 6 weeks. His cock was the first and last cock I ever jacked off and I could have gone on mutual jackin' with him forever.
