In recent weeks Vivan & Dana @ WB took really good care of me in that department. Please do not confuse this Vivian with Miss. V, Vivian is good but still no where near the legendary Miss. V.'s standards. They had since left town and two new ladies are here, if it is the same Linda, she was really good to me.
Now that I have your attention, please follow Cabinmon's advice, go to CAF, read the reviews here. I personally love Asian micros, try one of the reputable ones, like SBB or WB. They don't care what you do in the room, you have your hour and when time's up, you leave. Just remember, if you ask, you will get a rub; if not, it is straight down to business. Dont expect a great massage; but BJ and FS is guaranteed afterwards.
If you do not want to go to a micro or want someone non-asian, check out the massage section of LL, AMPs and some indys advertise there, most of them (except for Terwillegar Tina) offers FS. If you want to know what WB or SBB mean, go to CAF and use the search function. PM me if you do not know what LL, CAF, AMP etc. are.
Whereas looking for a RMT who offers FS at a spa, nothing is guaranteed, huge YMMV, I agree with Bob, very rare. If you look up Amy (the lady with many names), is probably as close to a sure thing as you can get, even then, I still feel obligated to add YMMV. Use the search function to find the legend yourself.
Just a long friendly message to say, if you are looking for FS, you at at the wrong place for information.
