OK… I actually have a MODEL SCENE that you just need to duplicate.
Find the very first Hustler Barely Legal and look at the scene with Bunny Luv and Herschel Savage (as I recall). There was another girl in the entire scene too, but the hot part was just the couple.
Especially the laid back reverse cowgirl slow grind on the bed after the shower… while her hair is still wet.
Apart from YOUR scenes, that was one of the hottest I have ever seen. Find that scene and just shoot it again with you and Marcello. Maybe get a LITTLE closer with the camera, but NEVER let the camera get so close that we cannot see your face.
