I've asked this one before, but got no help. I thought I might give it a second go. I can tell you two things - what I remember, and what I think I remember.

I remember she was a brunette, she was laying on her back with her legs folded back, exposing herself, as he entered. She's on the edge and he pulls out. She is desperate and reaches down to rub herself those last few times to push herself over the edge, but he smacks her hand away. She looks desperate and distraught at not being able to cum and he teases her for a moment as she squirms. It was, obviously, part of a larger video. Very professional, not homemade or cheap.

What I think I remember is that, at the start, he explains that her husband hired him to train her. Why you'd hire someone else to do that I don't know, but that was the premise, I think. She doesn't seem at all upset, even twists her wedding ring in a close up.

I'm sorry, I know I just described... Generic porn. If you can help, that'd be great.
