Whole foot in ass?

Not a story, but a request I'm hoping someone can help me out with please. I found a video a few days ago where a woman manages to get her whole foot up a guy's ass, going past the heel. I posted a comment on it that this was the first time I'd seen this in a non-gay video, but then forgot to save it to my favourites. The picture quality wasn't great, and the background was a dark sheet or towel, so there wasn't much contrast between her foot and the bed but as it's the only one I've found I'd really like to get it saved for future "use". Many thanks Gary
