This good little slave has decided to give himself over to me completely, allowing me to lock him up in chastity and hold his key. He will only be allowed out if I unlock him. I decide what he does with his cock. Fortunately for me and unfortunately for him, I still have total access to his balls. I thought it would be fun to see how much my slave is able to take. I'll start by squeezing his balls between my fingers, then I'll take out my tools to inflict the most pain possible. I'll clamp his balls in my beautiful, shiny wrench and listen to him moan the whole time. Let's see how much this little bitch boy can take. Hopefully, I don't cause any permanent damage!
