Lucky you, as ever.
From memory and I'm 99.9999% certain this was on some swingers' forum, it said there were two treatment rooms staffed by a crew of Thai grannies in tracksuits or EEs in bikinis. Extras varied from just solemn HE + touching through to naked, but the rates sounded absurd.
If you think about it, your average hairy arse who's spent the night there seeing a parade of men's cocks and getting not the slightest sniff of action may be more in the market for sexual release and not thinking straight when it comes to £££.
Never had the massage there so cannot comment, I can say the South American was very skilled at putting on a condom with her mouth but was loathe to let on too much with her partner there. If I had to guess I would say she was turning tricks.
Only went there twice, did not enjoy either and never fancied the couples night after that, neither did they as it was always late after her shift and on a Saturday they would be at the club, I recognized her as one of the topless ones I saw.
I miss those days when the clubs were not sausage fests, did you ever go to that converted shop on Chadwell Heath High road ? Nice bar and lounge area, sauna and showers behind it, 2 rooms upstairs, neither lockable, both largish, had some great nights there. Late 90.s I would think.
