Zombie's Rule

People have recently been saying that soon the world will end. Their fortune has come true. The world has ended and zombies are about to take over it. People are dying in increasing numbers every day. It was only a matter of days until the virus spread over all of America. The virus shuts off the higher functions, and as such bypasses the conscious mind. All that is left is one basic script: Breed and Feed. In its final stages, it reworks the body's digestive system to a worm like state where enzymes break down proteins in the stomach and directly feed the "brain" Another tube feeds the same enzymes to the reproductive organs. None of that mattered to the survivors though.
The zombies couldn't be stopped like normal people. These zombies cannot be killed by normal means. They can only be killed by a gunshot or knife to the head. It started when the virus was released in all the graveyards across America. Bodies rose from their graves and went to the cities that were nearby and started to take over. After the virus struck strongholds appeared but in a matter of days they were gone. Zombies kill all males who get in their way no matter what...
Which story do you want?

Sam's Story: Her story takes place right during when the virus first struck her hometown. She is 18 year old senior and around 5'6 in height, people called her a Goth and guys and girls in her school called her slut. She dyed her hair pure white, fair light skin, and always wore black tights, black shorts that showed off the outline of her panties and stopped just above her tights, fishnet shirt that stopped just before her wrist with the sleeves, black shirt over a black lace bikini top and her fishnets, fingerless gloves, black eyeliner, white or black panties, and DD cup breasted. Loved to play with guys of the school, which is how she got to being called a slut.

Terra's Story: Story takes place four years after the virus was released. She is 18 and around 5'5 in height. She has short, blonde hair, pale skin, and wears a black and white dress that stops at her knees, black leather bra and matching panties and B cup breast.

Alex's Story: When the disaster started she took time out to learn everything she could about them. She learned that they cannot see with their eyes or have a sense or smell but have enhanced hearing. It has been 2 years since that day and so far she has never been caught by them and is now eighteen. Alex has silver hair that stops at just before her butt, pale skin, wears black spandex shorts that show her panties outline and have "spank me" written across the back, firm ass from volleyball and track, white tight top that shows off her CC cup breast and nipples, wears no bra under the shirt, has a scar under her left eye from a car accident when she was a kid.

Other girls? Feel free to add a tale of your own. I am trying not to steer too far from what he was working on so that is why this chapter is similar. Also try to keep it in first person.
