Pastel Goddess - Ballbusting Training for Short Slave Femdom

My short slave has a super tiny dick that deserves to be in pain. Ive decided to start training him to have his balls busted regularly. He is out of chastity and doesnt know my intentions as he seems excited to finally have release. But the only reason its not shriveling up in a cage is so I have full access to bruising his little balls with my heavy platform shoes.Since this is his first ball busting, I go very easy on him. Still, he sometimes tries to jump back out of instinct. My training will teach him to endure blows to his balls by remaining still and taking the hits head on. Whenever I do a heavier kick, he really feels the pain.As I continue to kick him, I make fun of his tiny penis with harsh verbal humiliation. I taunt his desire to let me fuck him by showing him the ass he could never have. Im way too much for him to handle. When I deliver a final kick that knocks him to the floor, I tell him that well be doing this everyday until he can take even longer beatings.
