They throw themselves on each other immediately after they've walked into the house. Then they run up to Jo's room and hop onto the bed. At one point Jo asks Vera if she's sure she wants to do this. Vera's answer comes immediately. She grabs Jo, pulls her in and kisses her hungrily.
Jo has said that Vera is her favorite on-screen partner, and it certainly shows. I have never seen her so into it before, and I know that she nearly had an orgasm way "too early" in the scene. This is something which you can actually hear Jo start laughing about.
