What does he need balls for.

Slave beau is bound in a body bag and rope bondage. Theres no way for him to squirm or go anywhere. He can only focus on his naked cock and balls. Maya Sinstress squeezes and slaps his balls with her leather gloves on. After a lot of ball slapping, Sinstress puts two electrical bands around his dick and balls. He moans and breaths heavy as she cranks up the electricity. Sinstress does hand over mouth play and some genital flicking in the mean time. His genitals are really useless in general. Why should he be allowed to keep them. Sinstress gives him 2 options for how to get rid of his balls. Will it be by a burziddo or bashed with a hammer. He is terrified of both options. She hammers his cock a bit as a warm up to what may come. Which method will she choose to castrate him?
