You are laying on your bed 3 days after your crotch changed. Your just masturbating with your cock while you still have it. Slowly you feel a pressure in your ass and you wonder whether it is natural or part of the experiment. You go to get up when you are hit with a huge blast of pain as a loud crack flies through the air. You black out but the changes continue. Slowly your hips flair out and hive you the finishing touches on that perfect hourglass.
