Knowing that you'll pass out from hunger and likely be raped or even worse that you will die if you don't eat, you take a chance on the cheese wheels and slices, they are all whole, uneaten, and they all look clean.
Taking the wheels and slices of cheese you begin eating a couple bites of wheels and slices, you feel full so you wait for you stomach to digest the food, then you begin eating again. After you eat all of the Cheese of both Wheels and Slices, you feel full enough to continue on. Not filling up to feel sluggish, you ate just the right amount.
You make your way to the park exit, when you feel a weird tingling in your gut. You moan as your stomach churns. Feeling an odd pinch above your butt, you scramble to the nearby bathroom. Checking to make sure no one is in there, you turn to see yourself in the mirror. Immediately you notice a tent in the back of your pants, slowly snaking down your butt towards the back of your knees.
Popping your pant’s button and unzipping its zipper, you pull it down enough to see a long naked hairless bareskin pink mouse tail hanging over your panties. It snakes and curls as you examine it. Your Mouse tail is as long as you are tall. One of the Cheese Wheels or Slices must have been contaminated, poisoned, or cursed in some way.
You are being transformed by the mutagen!
Your Tail makes wearing pants, a shirt and underwear all uncomfortable, so you have no choice but to remove them all. This is embarressing and you wish you didn't have to do so but comfort is needed more than modesty and decency. Because it is so painful when your tail rubs against whatever clothing you might have worn, you can't pick up anymore clothing or wear them anymore. You'll just have to go the rest of the journey nude, naked, and exposed. You just hope that this doesn't make any of the mutants desire you even more than before since they will see you in your full naked form. And some of them might even love you even more because of your tail.
You need to hurry! Perhaps medical staff beyond the city blockade will have something to counter act the mutagen. Hopefully they can figure out something to shrink or surgically remove your naked hairless bareskin mouse tail. You have to hold out hopes for something. But if you don’t get to them before you change completely, it won’t really matter then.
