I'm going to wear you down, cuck, I'm going to break you, I'm going to make you beg for mercy, and then I'm going to deny it to you, because that's what you deserve, that's what you want, and I'm the one who gets to give it to you.
While no one will deny torturing your cumslave is fun, relaxing, healthy and natural, it is important to reward them every once in a while, so that they still have hopes for you to crush later.
