I've been looking for this scene for a while to post here and finally found it. This is one of the best flip-flop fuck scenes I think I've ever seen. The two leads seem to be totally into each other and what they're doing. They're at once inventive, playful, and totally horny.
If you prefer watching this on the source webpage or to download a free copy to keep and watch at any time, you'll want to click here. If you can't view right away, I recommend downloading and saving for later, because this might not last long at the website where it was found.
