Prostitution activity now can now be labeled as an erotic party

Or maybe you are too young to understand how things run

In order to keep the parties happen, she needs a list of escorts and paid them to go to the parties. Maybe in some rare case that some ladies wanna fuck with a group of strangers. As a man, would you bring along your partner/gf to erotic parties? Some may do that. But there are always not enough females to go around for everyone.

If no money is involved, i could believe it the so-called swinger party.

She had to label something illegal to make it looked and sounded like participants are voluntary, and therefore not violated the law. No reason for her to speak publicly and truthfully about the dirty side of things she's done. That's her trick of the trade.
