Bear with me on this (no pun intended!), but could our mystery lovely lady be
Torrey Pines?
This scene, "Bear Makes a House Call", was released in 2009, which would coincide with the early stages of Torrey's career, as she started in 2008 at the age of 29 or 30. This would also make her around the same sort of age as our girl, who looks like she could be in her early 30s too.
In some of Torrey's earlier scenes, before she went platinum blonde, she had reddish hair, and like our girl was rather freckly.
Both ladies are a similar height, Torrey is listed on IAFD as only 5'2", and our girl is similarly tiny, as can be seen when she stands in her Dancing Bear scene.
Torrey also has another Dancing Bear scene in her credits: 2011's Happy Birthday from Dancing Bear, in which she delivered a BJ in much the same style as our girl, so it's not unfeasible that she might've done more scenes for them.
Finally, and I did say to bear with me with this, Torrey usually wore metallic shoes in her scenes. Our girl's choice of footwear? A pair of gold high heels!
Any thoughts? Am I totally wrong? Probably! But could it be worth considering?
