Well that's disappointing.

It was awhile back i first learned of this. It was on Pornhub. It's not there anymore I assume for copyright reasons. I found it on an adult DVD store. Doesn't seem to be a parody or even scat just anal. Maybe it's hard-core anal where they don't clean up before hand but I'm not about to pay to find out.

Sorry if I've wasted your time but I hope this amused you for a moment.
