Learning to be your cock slut

I want to be your best cock sucking slut. However, I have a gag reflex that must be trained out of me first.  Watch me try to overcome this LIVE on film without prior practise, slowly altering the pace and depth of thrust of my fucking machine to penetrate deeper and deeper!  As I increase the level of training you can really begin to see me struggle, gagging on the cock with tears forming in my eyes.  I don’t make it balls deep in this clip….this will require more training another time!
