i wouldnt say that's a requirement for a FMF threesome, but it is fun to watch.
i would say that, as best as you can, 
make sure that the two women get along w/ each other.
and if they're really into each other, you can watch [letting your system recharge], interact helping one side or the other, or jump in and do one while the other does her as well.
