I used to pull off like that when cum was shooting. Then one day I had a hot young guy in a bathhouse bounce cum off the back of my throat. Since that night, there is no way I can pull my mouth away when the cum surge starts. I mean no way. More often than not, that is when my cock starts emptying my balls on the floor. I have such a clear memory of how that hot cum felt on the back of my throat. Wow
