It sounds fun but it could get messy... you may need to promise a certain number of clients to the escort for the evening. Plus, if you told all your friends that the "hot" guy is available for free sex (on the house), i'm sure all 30 will take you up on the offer. Also, are your friends prudish? Some may not want to have sloppy seconds, or thirds, or fifths... Best solution is to order an escort for each guest!
