Sucking on an old friend’s big cock (cheating)

My friend from high school was in town with his wife for our class reunion. He came by my house to visit and I saw him look at me in a way that turned me on. His wife ran out to the car to get her phone charger, and in that short period… I whipped his cock out and sucked it until I heard the door. Just for fun, he didn’t complain.
