The dragon skull was about twice the size of Alidia, so pulling it down does not get too many results, but it does drop down a few inches, allowing Kathrine to look between the teeth, and see a door set in the wall behind the red dragon skull. The thick cock dropped a few more inches, before clicking into place, at about chest height for Kathrine. Alidia could impale herself easily at this angle, even if it was a bit bigger than what she looked capable to take. The cock suddenly started to ooze a thick liquid, like as if it could sense the four females, and knew what was needed to get the skull's jaw to drop.
