Ler’s file these devices under “severe testicle torture” … Check out these CBT devices available from Mr S:

Acrylic Ball Press: Turn the wingnuts tighter and tighter and watch his balls flatten and listen to him beg and plead for mercy!

Acrylic Ball Crusher: Once you lock this nut-trap on, you’ll begin to see that look in his eyes as you gently turn the dials and the nuts get even redder … just one more turn?

Captivator Electrical Ball Crusher: Two times the surface contact to ensure no area on his balls gets away from you. Lock him in and let it rip! This is a 2-channel electrical device, with 4 inputs for the wires coming from your power box.
