Your Adam's Apple should rise significantly... You can also put the tip of your tongue down under your lower teeth behind your jaw bone and it may give your better upward movement... You may feel some pressure in the back of your throat or nose as your tongue presses against the soft palate... Very much like a sustained swallow and you'll have to be holding your breath so a few passes with breaths in between.
Play with that as you draw your skin down or to one side or the other and you should be able to get it fairly comfortably.
