Did you go? What was it like?
Yes I went and here is a delayed review:
Arrived promptly at 7pm to find a few guys waiting around and no ladies in sight. Not even an organiser. The party seemed independent of Le Boudoir - the receptionist took my £80 cash but didn't seem to know much else. Hung around for about 15 minutes until a 40-something swinging couple arrived and started getting busy and we soon joined in. A single blonde working girl (early 30s) arrived later so just two ladies and about 8 guys. So typically a lady was attended by 3-4 guys - one banging her pussy, and the rest alternating oral and hand attention.
Shot my first load whilst banging the swinger lady in missionary. After some recovery time joined in again - this time she was up for DP. Another punter and myself put our hands up (first time for me!) and after lubing up I had a go with him below and me kneeling above. Found this position a bit awkward and I wasn't quite hard enough to enter her already full pussy. So I swapped positions (with me below) and managed some deep penetration. The other cock was hard enough to join in, the tightness of two cocks in one pussy was quite something and it didn't take long to blow my next load. Despite the slow start and lack of ladies that made it all worth it.
Recovered a bit and moved on to the blonde where I finished with a final load over her breasts. By which point I was well and truly spent.
If it wasn't for the DP I would have been a bit disappointed by the slow start and seeming lack of organisation. But I may give it another go.
Beware they do take your details and check your ID - so might not appeal if you want to be discrete.
