Lilly and Susie are twins, born on the same day just a few seconds apart. It is said because of this that they are inseparable. Their personalities are far different though, as Susie (being the older one) is quite nerdy, enjoys reading, and is quite shy. Lilly on the other hand is quite outspoken, flirtatious with others, and is often called a brat. Although their differences they still never really stray far from each other, to the point where they demanded a doublewide bed and a shared bedroom even though they are 10 and were offered separate bedrooms.
One day their Parents leave them home for a while to go to a party for a friend. The twins decide to go play on their father's computer while he's not home. While messing around on the computer they discovered porn and were quite intrigued. It awoke a strange and confusing feeling in both of them. Unsure of what to think about the porn they found they watched some more and stumbled upon lesbian porn.
After watching a few videos Susie says "I don't know Lilly, I-I think we should close it. What if Mommy or Daddy walk in, you know we aren't supposed to play on Daddy's computer."
"Aww, is my big sis gonna chicken out because she doesn't want to be seen watching sexy videos?" Lilly teases, "Come on, its not like Mommy and Daddy are gonna be home in the next little bit, they went to that party, remember?"
"Yah... but-"Susie tries to say
"But nothing, there's no harm it in sis, come on, it looks so nice." Lilly says, mildly blushing. She was already getting turned on by the thought of showing her twin sister these naughty movies. Her mind started racing at all the possibilities; what could happen?
