Foot night is all about guys worshipping the ladies feet. You pay a fee to get into the place they are holding it, then you can negotiate with each individual lady on how you would like to worship their feet. Some have no problem with you licking, sucking their toes, etc. Others don't want that, but they might let you smell their pumps.
It's all pretty much between the guy and the girl. They try to stay "legit" and unlike what goes on here on the board.... so anything else you are seeking would have to be negotiated to be done elsewhere.
Some of the ladies are prodommes, some are simply into having their feet worshipped. The local woman who handles a lot of the organizing handles most of the local foot recruiting.
