The champion in this category has to be Victoria Zdrok.
She received her bachelor's degree at the age of 18 with a 3.96 GPA, and then went on to earn a law degree and a PhD in clinical psychology.
She has also been a Playboy Playmate of the Month, a Penthouse Pet of the Year, and been in several softcore films. Some of her softcore stuff pushes the boundary between softcore and hardcore; see, for example, www.celebritymoviearchive.com/tour/movie.php/5082
The still image posted seems to be partly photo-edited, or the video was. In the top-right pic, her body appears to be partly rising out of the man's hip. I am guessing that she was handling a dildo.
I've not seen anything else of the movie and am not likely to anytime soon, but you can check out 4 short clips here: http://www.sog10.com/gallery01/celebfli ... index.html
Although it's a bit small, by 12-string standards, that is pretty clearly a real dick she's jacking on (clip 3 in particular, but I think there is some more in clip 1 or clip 2 -- those are stranded in a miscellaneous clips directory that I'm too lazy to search through, so I haven't reviewed them this evening).
