There really should be a genre name for the type of porn when it looks the domme has forgotten there’s a submissive in the room. It’s a small and somewhat odd niche in Femdom. I’ve never seen it in maledom material. It’d probably classify as a sub-genre of objectification and forniphilia, but at least in those the domme is typically aware of and making use of the submissive. In shots like this you get the impression she’d be surprised to look down and discover what she’s been resting her foot on. You can see another similar shot from the same scene here.
Based on the watermark I believe the original site for this has ceased to exist.
