Although sex in the animal kingdom has many offensive permutations, oral sex among animals has rarely been documented by science. But a team of Chinese and British researchers report that short-nosed fruit bats have oral sex AND copulate at the same time:
We found that female short-nosed fruit bats C. sphinx lick their mate's penis regularly during copulation, and that each second of licking results in approximately 6 extra seconds of copulation. Copulations also last longer if licking occurs than when no licking takes place. Our observations are the first to show regular fellatio in adult animals other than humans.
As you can imagine, this is only possible because fruit bats are far more flexible than humans. If you click here, you can see a graph of copulation time illustrated with a lovely little drawing of a couple in the act, by Mei Wang (not making that up).
And if you click here, warning:
The video is sexually explicit and was edited and soundtracked by the researchers.
The abstract of the article concludes:
At present, we do not know why genital licking occurs, and we present four non-mutually exclusive hypotheses that may explain the function of fellatio in C. sphinx.
I think these guys just don't get it, because when you read the whole article, it turns out that not one of those hypotheses is "because it's FUN."
You can read the entire paper here if you want, you sicko.
