It is time for me to demonstrate for a slave how much power I have! So the slave is on the ground, and I start trampling his balls and his dick. But I can do more. I start jumping on his “equipment” because I want to inflict so much pain as possible, I want to break him.
I kick and trample him from behind, and you can hear his screams as I do so. But he still won’t break, so I get on the couch and jump directly on his dick and balls. But he is still resisting and wants to play more!
Maybe I am so charming that a slave can’t resist no matter how much I inflict pain for him?
