You'd be looking to purchase the scene.
Thank you for your help, I am so happy that I found the title.
I did a lot of digging - so far nothing.
A final question: Could you recommend other forums?
There are other places. We just can't mention their names here. Those sites contain "questionable" and shared content. I'll leave it to your imagination to figure that statement out.
In the meantime, you have the working title, the director and the people starring in it, try xvideos and xhamster. Put in
Sally Layd as the person you are looking for. If you get a snippet of the scene (between five to seven minutes) take screenshots of what you see. Put those screenshots into Google, Tineye and Yandex.
These for example ...
... may just be too small to get anything.
Good luck.
