First ever was Tokyo Spa in downtown Hartford, CT in November 1989 (primarily an HJ place) followed shortly thereafter by Hong Kong Spa in Waterbury, CT, an FS place that even offered prostate massages. Waterbury featured 10 AMPs, all were FS and did great business until the local police and the State Police combined to raid and shut down all 10 places at the exact same time in April 2006, an incredible waste of manpower and taxpayer funds as 50+ officers were involved. The raid generated a lot of TV and newspaper press and a post that I had written (on a different website under the same "Mighty Spearsman" handle that I've used since the 1990s) was mentioned as evidence of what was going on in the 10 AMPs.
Turns out I knew one of the 50+ officers. I was tempted to identify myself as the MS but decided to keep quiet, although I did tell him that I thought it was a waste of resources to arrest people for what was going on behind closed doors considering the level of serious crime in Waterbury, he just shrugged. Not sure if Waterbury has improved any in the 18 years since that raid.
First AMP in Manhattan was Gold Spa just off Herald Square in Midtown, best known for Mimi who gave the best BBBJTCIM service I've ever had, I was a regular here for almost a decade (two locations). Mimi later became the MMS but still had sessions with old customers if they were willing to wait until closing time. The last time I was there was December 2008. Mimi probably qualifies as a GILF now but I'd still love to hook up with her again.
