This lady, Sarah Fosterman aka Penelope, according to the iafd, has appeared in thirty-seven (37) films as a performer.

See if you can find the scene using the iafd and/or the male co-star listing in its screen shares area. Try to match these pictures of the scene to possibly the adultempire.com website or to the data18.com website. Data18.com will have thumbnail images of the scene. Adultempire.com would have larger pictures of the scene.
The thing is that this film might be so old that it won't be in either data18.com and/or adultempire.com. If that is the case, then this thread would not be able to be answered and you wouldn't get an identification of the lady or what scene or film this is.
Good luck.
