Zipper Challenge

Description: What do you like more? is it the look of pleasure on my face applying agonizing pain to your cock and balls? or is it the rush of endorphins and adrenaline from the pain itself? we both know you can't resist me-especially when i'm dressed in shiny latex. i have a task for you. let's see how well you follow my instructions. it's one thing to obey when your cock is hard. though it's another matter when that's not the case. how deep is your submission and masochism?
