Orbital Fish Hook
The orbital fish hook is a predecessor to the normal fish hook used on your girl while having sex. Since the jaw is soft, pliable, and bound to tear eventually. You hook your finger inside the orbital bone of the eye to make sure you have a proper hold during coitus. If the jaw rips she is scarred forever but the orbital bone will stand the test of time.
My girl and I were doing it doggy style last night and right as I started banging her real hard I reached up and obtained the orbital fish hook... it was a little uncomfortable at first but after she saw the beauty of not having to worrying about her jaw ripping she really dug it.
