You sneak under the door and into Bethany's room. It's still a stunning sight to see everything in a dorm room as a skyscraper towering above you, and you'd love to stop for a while and just admire the view. But it's still dark in Bethany's room, and you know that means she's still asleep. What you don't know is how much time you have until she wakes up. You have to turn into her panties before then. You'll have plenty of time to ogle this luscious brunette later.
You do the same thing you did in Kristen's room: you enlarge yourself just big enough to climb up onto the top of her dresser, reach over and pull open the drawer just a bit, shrink yourself back down to a couple of inches, and leap down from the top of the dresser into her panty drawer. Once again, it works like a charm, and you take a moment to look around to see what kind of panties you want to become. You start hearing some shuffling around outside the drawer, but that could be anything. You haven't heard an alarm, so you know Bethany's not up.
This time, you decide that simpler is better. You look at a pair of white cotton panties, and decide those will be the pair you'll transform into today. But to make sure that Bethany doesn't see two identical pairs of panties where only one existed before, you stuff the original pair underneath the pile. Since the panties are much bigger than you are, this takes a few minutes. Not that you don't enjoy the experience. You then turn the gun to transform and prepare to shoot.
Just then, everything shakes from under you and you fall over. You realize instantly what's happened: Bethany is awake, up, and opening her panty drawer. With no time to think, you fire at yourself, turning into a pair of white cotton panties. You hope beyond hope that you didn't blow it and that Bethany will wear you today.
