Watermark Identification Request

I have a set of clips that I'm trying to figure out where the came from.

In the upper left corner of the videos is a water mark of two animals, maybe dogs or horses, or possibly unicorns (poor video so I can't really tell,) that are fucking doggy style. The male animal is black and the female is pinkish-red.

Does anyone remember seeing this watermark and what site it came from?

Thanks

How about a sample picture?

Here's a screen cap of the video. The logo is upper left just above the girl's head. Anyone know where this came from?

Thanks
