It's a very rare occasion he gets to feel inside me 😈 and it comes at a cost

As most of you know my sub has a sex life that consists entirely of ballbusting. He is caged most of the time, pussy free and is only allowed to cum while I beat his balls. You could imagine how excited he was when I told him i would let him feel inside my perfect pussy. Although there is still no pleasure without pain for him 😈
