Lady Shay felt betrayed by her boyfriend to the extent that she had to dominate and humiliate him badly. She did it with her forced bi femdom and she made sure that he knew how pissed she was at it. She was not going to cheat back but she was going to make sure that he was dominated and tortured cruelly so that it would never cross his mind to do it again.
Lady Shay had loaned money to this guy but he did not give it back as agreed. The mistress gave him more time and asked him to pay back what he could but he avoided her and did not want to pay back. So she had to make sure he understood he had to pay back what he owed her and that is why she used forced bi femdom on him. He paid back in a week.
Lady Shay knew that her boyfriend took her for granted and she wanted to shut that shit up. And that is how the mistress chose to force her boyfriend to jerk off in front of another man who was naked. And she told him she would only stop if he managed to cum. It was almost impossible but he gathered courage and managed to cum so that the whole thing would be over.
Lady Shay had two losers and since they were losers, she felt that they did not add any value to her and so she used them for her own fun and entertainment. One of the things she had them do is forcibly turn bi. She made them suck each other and do all manner of naughty and kinky things and she did not care that they were straight. They had to do it all.
These guys thought that they were smart enough to con lady Shay and to get away with it but it did not happen the way they wanted. The mistress cornered them and she punished them in a way they had never imagined was possible. She forced them to be bisexual by having them suck each other's dicks and when they were done, she had them lick each others butts and assholes.
