Mistress BlackDiamoond wanted to find out how much pain her slave could handle. So she tied his balls and she crushed them as hard as she could. But that was not all. She also inserted a finger in his butthole but when she noticed it did not work, she inserted a strapon and a giant one at that. She knew it was working from the way he screamed and cried.
Mistress BlackDiamoond does not like someone trying to contradict her especially in her area of expertise. This loser tried and she had to teach him a lesson. She sought him out and pretended to want to talk about issues, but she was only interested in punishing him. She used a strap on to teach him a lesson. She forced the dildo part of it into his ass and he screamed in pain.
Mistress Gaia was tired of torturing and humiliating male slaves. She decided to try a female slave and it was awesome. She undressed the slave and she made her suck her strap-on. The mistress then poured hot wax on her back and enjoyed as she cried in pain. Before she was done, the mistress used the strap-on to fuck the mistress both in the ass as well as in the pussy. She got tired of the female slave and got started on a male one as well.
