Anybody ever get a rub down from 2 girls at the same time?  How do you tip?

Usually if an mp offers that service they will have it listed.
For independents like me I charge double the rate since we are both doing the work.

and I tip each gal individually, as if I had done a 1 on 1 session with her.

During the one time I tried it, one girl left towards the end so the other could do the soft touch.  Do usually both of them stay the entire session?

I do when I get to do a tandem .

I would tip them equally imho
