Mistress Mina places a spiked ball stretcher on her slave jimmy, and squeezes and pulls on it, digging spikes into his cock and balls. She grabs him by his balls and forces him to the ground so she can trample his cock and balls with her high heels. Using a handheld electrical device to his balls she makes him scream in agony. She removes the spiked ball stretcher and shoves one of the points of the zapper down his urethra, using his pre-cum as lubricant. Then she tramples his body and his cock with her stocking clad feet.
