This is a curse file. It gives you the large cock and balls of a beast, but also has other effects. It makes your muscles grow and makes you act and look a little more beast-like especially during the night. I worded it so that there is no end goal but to just keep growing. There an echo on the voice and there is rain in the background. This can be combined with the companion file "Alien Cock and Balls", it uses much of the same script and is more effective during the day.
