I'm a long time huge fan of both KissMeGirl and SloppyGirl. I always fantasize about how it would feel to be kissing each of the girls.
Have you thought about adding a few minutes of PoV kissing into the scenes? Each girl would essentially open mouth kiss the camera, giving the viewer the illusion that he's kissing the girls. I'd also love extreme closeups of the mouth and tongue.
I actually have a lot of experience filming such scenes myself, and I can offer some suggestions on how to setup the camera so that the shot isn't obscured by too much saliva, and the sound remains clear. I have seen some fetish vids where the girls are kissing a glass pane, but that rarely works well. Instead, I have the girls lick and slobber right up against the lens, protected with Saran Wrap, and record the audio separately (so that you don't hear the crinkling of the Saran Wrap).
I have lots of sample videos I can share with you, if you're interested in seeing what I mean.
