Would this be illegal?

Let's say I have a lot of money. More than I can spend. I decide to have fun and put up ads everywhere that say that all guys, no matter what age, are allowed to come and participate in a bukkake of a chick who is in on it and gets paid well.

None of this will be video recorded, but I will merely sit there on a throne and watch this slut be cummed on by hundreds of guys for hours that evening.

Would there be anything illegal about this? I mean in most Western countries.

A. She would be drowned in cum, there would be alot of people.
B. You would have to call up a legal show and see.
