You're a good, obedient boy, you last all year for me. And I always make sure that your frustration is kept at its maximum threshold, I always play with the limit for you. So, unfortunately, you sometimes want to crack and come before I decide to do it myself. You've made it clear that you can't take it anymore, that your balls are full to the brim and that you'd like just once to enjoy a real orgasm in my company. Well... So be it... You want to come? How far are you willing to go to come? How unbearable does it become to have to remain chaste for your Mistress so that you want to suffer so you can cum? As many seconds moving that hand up and down that filth as whippings to endure without flinching. That's the rule for wanting to break your chastity.
