This is part 3 in a 10 part series challenge! I intend of training you like a good boy to cum on command no matter how long I give you to jerk your cock. Today you will have a total of 8 minutes to jerk and cum for me. The price on the premature/not able to cum tax goes up for every minute that goes down. Eight whole minutes should be easy peezy for you. If not I will enjoy the 70$ cum tax you are going to send me.
