I doubt anyone on this board will actually name an MP where FS is available as it is illegal. However, through PM’s and innuendo over the years, it is available at many locations but it depends on the lady. Some are known to offer, and some are not. Best is to hint at it in the room, “How’s so and so? Man she’s a wild one” or “I’ve had some good times in this room” and let the lady take the lead whether she wants to go there or not. That’s worked for me in the past. Coming right out with “How much to fuck you?” will not earn you any points in the chivalry department.
