You Sound like a Pig having an Orgasm.

The scene opens with Miss Xi already inflicting pain on her slaves balls. She uses one tool to hold the balls in place and others to squeeze them. The bound slave is whining and kicking like a little bitch. “You know what my favorite thing is to do to balls?” she asks her slave but before he can reply she starts to punch them relentlessly. Xi reaches into her box of tricks to reveal a magic wand. She applies it to the slaves balls which really gets him kicking. She then focuses on his tiny little cock and despite his kicking she decides to turn it up to high. She then wraps a chain around his cock and balls and then takes the electric wand to the medal. “I love electricity and metal” Xi says with a giggle.
