She's brought out her brand new device - a perspex vice that crushes the subject's bollocks flat by turning screws. With the slaves nuts in place, the cruel tattooed alt girl goddess starts twisting the screws and laughs as the slave's bollocks get flatter and flatter. He groans and fidgets with each cruel twist!
