After I told my GF that I've gone to erotic massage parlors, she expressed a strong desire to go with me, after I mentioned that many of them advertise "couples welcome".  However, I have no idea what typically goes on when a couple goes to a massage service.  Anybody have experience with this?  We're not looking for anything crazy - she initially just thought it would be hot to watch me get a HJ but we were wondering if the GF is expected to participate or does the GF get some action herself, i.e. fingering, etc.?  Or entirely up to us and the provider?  Any info would be great!
