Seeing as there was no other choice, Jon quickly downed the liquid. It went down easy, and was actually quite refreshing and tasted sweet. A 'click' sound came from the lock, and sure enough it was open.
Stepping out into the hall Jon felt as if something was odd with his pants. He looked down to see that his butt had filled out the back of the pants, and his hips had widened and made his legs look very feminine. A look further down and he saw his bare feet were now smaller and that he now had the habit of swaying his hips because they were so wide.
Noticing this caused his dick to become erect, but under the pants it seemed a bit smaller to his sight, for some reason.
