Good link.

For those, like MrWookie, who can't view it, it shows a woman from the shoulders up, lying on a bed. Granted, her shoulders are naked. She does indeed appear to have a real orgasm. So, she's naked from the shoulders up and making noises.

I think an argument can be made that this video is less NSFW than a lot of avatars on the site. Though, the image links on that page are obviously way out of bounds.
