You are sleeping in bed when a loud knock on the door startles you, you get up, get dressed, eat breakfast, brush your teeth and wash up and go to the door. The Mailman has a Package for you and it is the Chronovac 4.0. There is a Letter attached to the package it reads.
Congratulations on being the lucky recipient of the new Chronovac 4.0 with this device you can turn yourself into anything that you want provided that it is a living thing and not a plant, the Chronovac 4.0 comes with a CD-Rom that contains the Altering Software, a Portable Emitter, and a USB Drive that can be plugged into the USB Port, Using the Chronovac is simple you just click on the part of your body you want to alter and then it does the rest, you can even choose your gender or be neuter if you so wish, however you CANNOT become a Hermaphrodite, that means you cannot be both male and female nor having both boy and girl private parts nor having a Penis with Vagina and clitoris and urethral meatus holes and etc. You also cannot turn into a mix and match animal or more than one species of creature at a time. If you want to turn into another Creature you will have to press the revert button to change back into yourself and then you can change into the new thing you want to be. If however you hit Save when made made your Change Settings, then the Changes to your body will become permanent, so be careful and make especially sure if you hit save that, that is what you want your body to be forever, because you will never be able to change it back to how you are now as a tailless human or into another creature ever again. It even comes with a VR or Virtual Reality Simulator if you want to explore virtual worlds. But be careful because if you hit save when you are in the Virtual Reality World, it will become your Real Reality for eternity. Have Fun.
YIPPEE, you jump up and down with excitement, you get the CD-rom insert it into the Disc Drive of your Computer, attach the Emitter to your Computer, plug in the USB Drive into the USB Port and turn the Computer on, you configure and start up the system and you see your body as you are right now in front of the computer you decide that if you really are going to see your body change then you will have to take off all of your clothes so that you are naked, you take them off exposing your belly button, your penis, scrotum, testicles, and Anus.
