But does it make oral sex any better?

Some time ago I was accused of having a forked tongue. About 10 minutes ago I found out that if it were true, it would not only have made me pretty damn "cool" in the bod mod circuits, but also some kind of yogameister.

Yes. Tongue forking (or splitting or bifurcation) is a cosmetic body modification procedure that's been around for yonks. Now banned in some U.S. states, tongue forking as a medical procedure is achieved using a surgical laser but can also be achieved by one's self using the fishing line method (use your imagination for that one). With practice, it is even possible to move the resulting halves of the tongue independently of each other.

Tongue forking also has a historical background in the practice of yoga. To some it is the pinnacle of "Khechari Mudra", a part of Hatha and Kumbhaka yoga where the tongue is split and then "milked" until it is long enough to be turned back inside the mouth and flipped up to the epiglottis. It then is used in breathing exercises, the goal being to seal the body's energy leaks and become aware of only the internal thus entering a catatonic state, crossing back and forth between death and life.

Loads more info on the web. And in case you're wondering, no, I'd never get it done.
