You wake up to darkness. It is late at night. You forget where you are at first, but then you remember the shack, your transformation, and the abusing you gave to your asshole. You slowly drag your larger body off the floor. You realize you must have grown some in your sleep. You throw the last of the logs on the embers and stoke the fire back to life, finally bringing some light to the room. You turn to the mirror, and immediately realize how tall you are as you have to bend over slightly to see your face. You realize your a least nine feet tall standing up straight, but you posture has changed to where you lean forward slightly. This is because of your tail which is now three feet long. Looking in the mirror, you now seem slighty more T-Rex than human. Your skin is now almost reptilian everwhere now. Your hair has now started to disapear, and you now have a very noticeable muzzle which you nose is now stretched over. Liking these changes you smile revealing razor sharp teeth. They look very dangerous.
This reminds you that your hungry, and this is a good time to go hunting. You find your clothes, and then realize they wouldn't fit you anyway. You have to duck as you exit the shack door, and enter the cool moist night air. You feel the mud between your toes, and then look at your tracks. They look just like a T-Rex track out of Jurassic Park- very cool. You start off with a jog into the woods on the lookout for prey. Within minutes you find a deer. At first you stalk up to it, and when it starts to run, you sprint after it. You are much faster as a T-Rex and soon overcome it, leaping onto it. Biting its back, you quickly bring it down, and then bite its neck. With a jerk you rip out its throat, killing it. You immediately begin ripping apart the corpse, chowing down on its flesh, drinking its blood. You bask in the glory of the kill.
After eating most of the deer, you can't stop thinking how awesome this is. You're a fucking T-Rex and you love it! But thinking about it, you then you realize you will be hunted down eventually. You need a plan, or have to change back somehow.
