They are ok now and again. I think the no touching rule went out of the window a while ago. The best one I went to was just an arranged night at a nightclub. there was about 12 of us around 1 big table and we had the girls dancing on the table. We had a different girl dancing on there all night and only paid for 1 each.
I went to a scary one at a working mens club in about 1995. There were only 2 'girls' who were about 35-40. Their act was pretty much them doing things together and not in a teasing way, just full on everything. There was no stage, everyone stood in a circle with them going at it on the floor. They were sat on the floor, legs spread wide, spraying cream on 'themselves' and slowly spinning round and inviting pretty much all of the front row to come and lick it off. The night ended in them having full sex with some lad whose birthday it was. He was trying to get away to begin with but they didn't give up. His mates who set him up didn't know whether to cheer or run.
The best part of the night was the comedian picking on a lad infront of the crowd who looked about 16.
"Are you old enough to be in here"
"Yeah, Yeah i'm 18"
"does your mum know you're in here"
[big grin] "no"
"well you best **** off quick cause she's on next"
