You don't just get to cum whenever you want - that's not how this works. You're a submissive loser who have no right or control over his own penis... but I do :) Not only do you have to wait for my permission to cum, but I've decided that you're going to have to pay a cum tax in order to do so. $50 sounds like an appropriate fee for a pathetic bitch like you to be allowed to orgasm (but that doesnt mean I won't humiliate you the entire time).
