I've been there several times over the years but stopped going a couple of years ago.
They are mostly in their 40s and average looking. They'll give you a hand job for £20 but no more other than a feel of the tits through their clothes. It's all a bit grotty inside but I quite like that seedy side of things.
Once I had a stunning girl in her early 20s there but she wouldn't wank me off.
The last time I went I had a really fat, butch old one. She looked like a rugby player. She wanted to wank me off but I had to say no - the only time I've ever turned it down.
I haven't been back since.
