This wonderful thing is the idea of iconhellothereguy. On Skype a few weeks back, he told me about this cool new vore idea he had, and that was wing vore.
 
This is how it works, according to him: “There are little holes in the tips of pegasi’s wings, and when the pony is hungry and near another pony, those little holes will open up big enough to wrap around the latter. The wing will ‘swallow’ the pony gradually, which, since the wing is a very fragile and delicate body part, would make for a pleasurable experience for the predator. Once completely gulped down by the wing, the prey will be stored in a harmless, stomach-like pouch in the pred’s back. The pred then can choose whether or not to suck the prey down into their belly or just keep them in their back and ‘regurgitate’ them later.”
 
I don’t care what anyone says, this is pretty damn cool in my opinion.
