Didn't read. Saw that the link ended in "defecate", and decided probably not worth my time.
It is about a zoo keeper who's helping a constipated monkey defecate by licking its ****. It is as hot as it sounds.
Sounds like there should be another way and the zookeeper is actually helping himself to the monkey.
According to the zookeeper:
"We tried everything, and this is the only way! And it can't be someone else, I'm the expert, and I'll keep on licking for as long as it takes. And no, those ***** in the corner aren't his. They are another monkey's, but he's out at the moment. This one still needs more licking. Now let me do my job."
That's one job I'm happy to leave to the "expert."
Just in case it wasn't clear, that quote was something I made up.
