One sort of moment in girl-girl/lesbian scenes that's so wonderful, that makes me almost lose it - are the ones with pussy juices aka girl cum.
Preferably, they are in a bed, as that allows for full flexibility/movement, and it also looks visually appealing to see them on a bed as opposed to, god forbid, a table. They are in bed, they are and look comfy, y'know?
Criteria:
1. The pussy gets so incredibly wet and/or juices start to run down.
2. The lickers face/chin gets coated in the wetness.
3. Close-up shot of the two of them kissing afterwards, with all those juices on the lickers face/chin hanging. So dirty. So perfect.
Perfect example that covers all three points:
Example 1 - Girlfriendsfilms - Lesbian Sex 22 Scene 4 - Karla Kush & Scarlit Scandal
Great example that fulfills all three criteria. All one really could have asked was for more time with both the licking and close-up kissing but this is a great moment, regardless.
Example 2 - Ersties - Zoe B. & Sirena In Action 2
Great example of #1, if only the camera was placed more parallell to the licker (Zoe) so we could see her chin, which leads me to the next example...
Exampel 3 - Sweetheartvideo - Lesbian Stepsisters
Camera position, lighting and the recipient spreading her legs (Kyler) comers together so perfectly, so we couldn't see the licker (Braylin) doing it more clearly than this. Now if only both were fully naked and if only we had criterion 3 fulfilled...
