Great job by a hot bearded cocksucker, I think he used to go by Head for Hung in his younger days of filming himself blowing, he did a lot of bbc then to. Great to see you again, was always a fan.
Don't think it has anything to do with dick size. Some guys with massive cocks just dribble a bit of cum out (think Tim Kruger) while other guys with shorter dicks go off like a fire hose. You gotta know what type you are and aim accordingly :-)
