Mistress BlackDiamoond did not tolerate what these guys had done. They had conned her and they had to face her wrath. They expected her to make them pay her back but she did not want the money as she had plenty of it. Instead, she, with the help of her friend, turned the guys bi. They forced them by fucking them in the ass. She used her strapon on one while her friend used his dick on another. They also deepthroated them.
Mistress BlackDiamoond felt that this sissy was a good candidate for being forced to turn bi. She had to torture him and the best way how for her was to make him lick and suck another cock. And she also made sure he tasted the other man's cum before she let him go. It was a lot of fun seeing how degraded and humiliated he was by what they did to him.
