Yes, I believe this domme may have a bit of a leather fetish. Obviously in this case it is practical aswell since she looks hot as hell in those bits of leather. At parties dommes like this are responsible for more beatings of male slaves than any other thing besides pleasure.
Those male slaves see a woman like this and their eyes leave their beloved mistress and they strain at their leashes trying to follow her forgetting who holds the crop in their family. She certainly can’t help looking this good but I expect she takes some pleasure from chaos she causes in the male slaves aswell.
