Want my wife to put on a live sex show for a group of smaller guys

I would like to arrange for my chubby wife to put on a show for a small group of guys who's cocks are either average sized or small. I want to have her railed by a stud with a long fat cock, so that everyone can see how much pleasure she's getting from a much bigger cock, and see how satisfied she is getting fucked by a hung stud.
