Never heard of Endota, but just googled it and looks like they're everywhere.
Also looks EXTREMELY legit - of course, anything is possible based on the individual girl and the particular circumstances.
But certainly looks like a "Final Boss" scenario for turning a legit service into an erotic massage.
That being said, I'm glad you started this thread because these are my favourite punter stories. In the year of the dragon, I'd love to hear who has managed to slay the proverbial dragon.
