It's that age old question, which is more painful trampling or cock and ball ? The girls are curious as well, so they use the slave to find the answer. Sophie starts trampling the slave in her pretty pink high heeled shoes while Mistress Antonia puts the slaves balls in a vice and them. After a suitable amount of screams from the slave they ask him which hurt more. Alas the slave can't decide, so the girls switch places and the resumes now with Mistress Antonia trampling him and Sophie slapping his balls. Poor slave, hopefully he can figure out a proper answer soon!
