Instead of having the girls go at hard right from the beginning, I think it would be really hot if they tease each other first with long eye contact and maybe some lite kissing. They should tease kiss each other until they cant take it anymore and from there the action would turn into deep passionate kissing. I would much rather see deep kissing than tongue sucking.  I think katie st ives would be perfect for this scene because she is the best at deep kissing.
