Bats for oral sex

Classify this one under "weird and interesting."

Researchers in China have discovered that humans are not the only species that commonly engage in oral sex. Certain primates do so occasionally, but it's apparently unusual enough in the animal kingdom that scientists were surprised when they observed it to be a common practice among bats.

Specifically, they discovered that female Chinese fruit bats lick the penis of male bats as they're having sex--and that this prolongs the sex, "with each second of licking adding roughly six extra seconds of copulation. The bats spent almost twice as long copulating when oral sex was involved than when not." If you substituted "humans" for "bats" in that last sentence, you'd say, well, duh. But who knew it would be the case for bats?

The scientists theorize that there's an evolutionary advantage to longer copulation--perhaps a greater likelihood of conception, for instance--or perhaps the female bat's saliva aids conception or reduces disease transmission. Or, maybe the bats just like gettin' it on.

I'm sure there's a study out there that demonstrates the same result in humans. Women who suck their partner's cock get fucked better than women who don't; and men who eat their partner's pussy find her more receptive to getting fucked. Duh. But don't take my word for it--feel free to test this in the lab, so to speak. Here's a bit of bat porn to get you in the mood.
