Ring and reserve your spot at the party you want to go to, book as early as you can in case they are full. Arrive about 10-15 minutes before the party is due to start, put your money and any other valuables in an envelope which you put a name on and seal. This is kept safe for you. Grab a towel and gown and have a shower, then order a drink if you want one and the party will start on time. Then dive in or watch as you wish bearing in mind the initial half hour is usually when its the busiest although it can be busy for the whole 2 hours dependent on the punters who are their. Have a break at any time you wish and at the end of the 2 hours have a shower, get dressed, claim your envelope and pay the fee then leave.
So after your shower you just prance around naked?
Are there different rooms? Or are you all just crammed into a big sort of open plan living room, with sofas, and maybe a big centre sofa to get busy on?
Is oral / sex / protected?
If yes (as I think it would be) do you also walk around changing condoms as u visit each different girl? Or they ain't too fussy about that and just let you use the one you already have one?
