A sexual request made of one hot chick to another in which one straddles the face of the other while nude, and then slides down along her neck. like riding a pony, a little pony. pony necking.
She whispered into my ear "i want you to pony neck me" So i straddled her face and slid down her neck and squeezed just enough to choke her with my p*ssy. That is pony necking
