Headed to vegas in a few weeks and wanting to try a 3-way.   I have done a few in the past, but it always ends up being more about the girls taking turns with me, rather than all 3 of us working on each other.  

So which 2 girls in give the best 2 girl show in vegas?  I would love to find 2 hot girls that were really into each other.  I would definitely want to participating some, but would most enjoy the chance to watch 2 hot women enjoy each other first and join in as things progressed.

My preferences are early 20's and petite/athletic.  For reference, Jade Button and Harmony Taylor are the latest 2 vegas providers I have enjoyed time with (separately) in Vegas.
