I've had a number of duos and trios.
Most have been a little interactive - but very few with the girls french kissing each other and licking each other's pussies. The key is asking in advance and being very specific as to how interactive they are, then declining if you get the wrong answer.
Take a look at my reviews and you'll find a few that like to lick pussy and then share the taste with you after doing so, Jules and Angel at MKE escorts have been the best lesbian duo for me most recently. Read my review as to how to get the best out of them. Jess at Annabellas is semi-interactive, Kat, April, Eva and Gia also like to munch (MKE or Annabellas)
Let's keep this thread going, I'd love to find more bi-sexual stunners!
