I've had a number of Muse Mixers back when I lived in Toronto.
Basically, you start with one MPA for the first 15-20 minutes then a second MPA joins in for some FFM fun.
The first MPA leaves after around five minutes of FFM, then you spend some one on one time with MPA #2.
When there's about 20 minutes left, MPA #3 comes in and the transition is repeated.
You spend the end of the session with MPA #3.Each MPA hops in the shower after her stint is finished.
Nice visuals while one MPA is working on you.
The showers at Muse are big enough for three people no problem, so if you like that, they may be willing to provide some shower time threesome fun.
Some of the MPAs are more interactive with each other than others. Best to ask who likes working with who, or ask a fav who she likes working with.
It has always been an hour of complete bliss with periods of sensory overload when they tag team out and hand off the baton to the next MPA.
Something all massage enthusiasts should try at least once.
