I actually like it. I always tell my girlfriend to twist, bite, jerk and stroke my cock as hard as she can. She even stroke my cock in the movie theatre, suck it at the traffic light when it is red and going to Vegas (difficult to do on first class except with a blanket to fuck her when the light is turned off in the plane)
All my girlfriends get tired after an hour of jerking, sucking, and now I am going to tell my girlfriend to punch my "testicles".
I don't write stories. "Paris" is my sweatheart and only 5'4", 110 lbs, she can punch my "ball" all day long and I will go over there to fuck her NOW'PUCHING YOUR BOYFRIEND'S BALLS". This is a new thing: "PUNCHING YOUR BOYFRIEND'S BALLS" lol !!!!
(Sorry for editing, it is the first clip not the second one, OK)
