Lots of rumors about celebrities becoming high end escorts in foreign countries. First and foremost, I would love to play an Indian (or another race) billionaire hiring a famous US celebrity to bounce on his cock.
Short of that, I would happily play a director, producer or something similar against a celebrity who is desperate for a part or willing to give herself up for a contract in to the next "Avengers"-like property and solidify her career for a good, long while.
I can use a PB of your choice or a real life Producer/Director if that is more your style. Who would like to play?
