My slave has shown he can take a good amount of pain. He's definitely earned the privilege of taking the most grueling pain for me, testicle torment!
First, I use chop sticks to isolate his slut sack. I use rubber bands to secure each side as the testicles are sandwiched between them. Then I bring some fun pastel colored, large wooden clothes pins and pin them into place on his scrotum. This slave's balls are so stretchy that I have room to snap two mouse traps on his aching sack as well.
With the last remaining folds of loose skin, I hook my mean metal clover clamps into my slave's balls. I attach everything but the kitchen sink to this pain slut's sack! I get my crop and loop the clover clamp chain around the end of it, pulling the chain to make the balls swing back and forth, furthering the pure testicle agony. All while telling my pain slut about how I'll be cropping off everything one by one.
I make him beg for the privilege to get everything clamped to his balls swatted off with my crop. After some good begging, I remove the clover clamps and start cropping hard on everything that's pinned to his swollen sack. I decide to take the mouse traps off my hand. Then one by one I swat those mean wooden clothes pins.
To really add insult to injury, this pain slut will have to endure my pointed boots getting kicked into his now broken balls. Ball busting after CBT? That's how I do it in my dungeon
