In the leadup to the scene with Elexis Monroe, Zoe talks about doing a scene with Justine Joli where she supposedly had an orgasm. Might not be the one she's talking about though, but here's A girlfriendsfilms scene with the two of them.
Ooops, the scene with Veronica Snow from Girls in White 2 scene 2 is above.
The Girls in White 2007 part 2 scene 4 with Veronica Snow is below. Also needs downloaded I believe. They named this series really badly. I have most of this series if you are looking for anything else, it's just not the best quality since it was ripped from DVDs originally in xvid codec.
