It's just doggy style. Doesn't really matter whether the girl is lying flat on her stomach, up on all fours, ass in the air with her chest against the bed, etc. It's all the same if you're doing it from behind. You can get all fancy with different [NOBABE]Kama Sutra[/NOBABE] positions and naming them goofy things like The Cat, The Ape, or The Splitting Bamboo, but every [NOBABE]Kama Sutra[/NOBABE] book calls the same positions different things. For example, there's spooning. Then you can take very tiny variations of that position where your legs might be curled up or arms might be wrapped the girl and give them different names, but it's still the same thing, is it not?
Just my two cents.
