It is great to visit one of these sure-thing places that seem to be more prevalent in Everett or Renton. They are a lot of fun and you have a very good chance of a very satisfying visit. With such high volume and casual access comes increased risk. But there is another way.
I'm in the middle, in Ballard. Ballard AMP reviews are seldom featured here and when they are they are lackluster.
However you can do better by putting in a little time. Find a place near your home that maybe offers at best a handy on first visit. Find a place that is stable with a lower turnover, as opposed to new girls every month. Make a few half hour visits and find your favorite masseuse. She may be young she or may be a MILF.
Visit her a few times. Be nice. Always be clean. Always be a gentleman. After a few visits make some gentle requests for more. If more is offered tip appropriately. With a relationship like this you may be surprised how far you get. With low volume like this your risks are less, as are hers.
I have had three ATFs like this. Yes, it took a little investment of my time but the rewards have been spectacular. I generally keep in touch over WhatsApp. My first was a MILF who moved away after several years. My second was young, under 30. She has gone fully legit and is doing nails and facials now. She moved away and I have not been able to visit her since although we keep in touch. Number 3 is current for a couple of years. She moved to a legit place and is UTR now with very few non-legit clients.
No point is sharing, because you won't get much until you earn that trust. Just sharing my experience.
