This guy knew the truth but he did not want to tell these mistresses. They were not going to condone that nonsense and so they had to punish him. They chose to teach him a lesson and did so with their biting femdom. They stripped him naked, tied him up and they had fun biting him all over his body including his nipples, his balls and his dick just to name a few.
Mistress Dula and mistress Valentina wanted to make sure that this slave learned to respect them. They felt that he did not respect them the way they felt they deserved and that is why they bit him as painfully as they could. One of them did it on the nipples, another one did it on his dick and they kept biting him all over including on his balls. It was super painful.
