I do not own any of the characters in this story, they all belong to the creators of the Simpsons, but the story belongs to me.

This is my first fan fic story, im not sure how good it will be. Keep criticism constructive please.

Im English, therefore i may use English words instead of American English words for example saying sofa instead of couch. I will try to keep this to a minimum.

This story contains scenes of a sexual nature and scenes involving incest, if you are offended by either of these I would advise not reading.

Setting

This is set six years in the future so all the characters are six years older, e.g. Bart:16 Lisa:14 maggie:6

Story

Bart Simpson was woken by the beeping of his alarm clock; he slowly raised hand to stop this annoying sound. He glanced at the clock to see the time was, it was 6:50 am, normally he would wake up at least ten minutes later, but not today, today he had a plan.

The previous night

Bart was in a fuming rage, that stupid twat of a teacher Mr Creed have held him back two hours after class, just for one little prank (all Bart had done was but salt is his teacher's coffee, it was barely a prank). he wondered into the kitchen, there was a note on the table "Bart, me and Maggie have gone to Lisa's saxophone performance, back at 9:00. You father is at Moe's your dinner is the oven. Love mum" Bart moaned as he heated up his meatloaf "Lisa is so great, we need to do everything she wants and just leave me to fend for my fucking self, bitch" after finishing his dinner Bart went up into his room to use his computer, it was old and shit but at least he had one.

But when he got on his computer he was angered even further, his mum had managed to get onto his computer and block "adult" websites. "I bet let Lisa helped that bitch" he grumbled to himself, to satisfy he urges he needed to go and use his sister laptop which was faster and newer than Bart's computer; yet another thing Lisa got from his parents, and what did he get when complained, what did he get a piece of junk. One thing he loved about this house was how all the locks didn't work, however it did mean he saw homer in the shower that nightmare would stay with him for life. Pushing that thought out of his mind he open Lisa's "locked" door. His opened Lisa's laptop and typed in her password jazzgirl13, Bart loved knowing Lisa's password.

Bart grunted loudly as he climaxed, his spunk went all over his hand on to the floor below. "Shit I have to clear this up" ignoring the porn film that had now ended Bart used his one clean hand to reach into Lisa's draw, he pulled out the first thing he could find, after cleaning his hand, his dick and the floor. Bart finally acknowledged what he was using to clean up with, it was a red thong. Bart was stunned, Lisa had a thong, "what a slut, i bet she's not a virgin" he started getting hard at the idea of a random guy fucking his sisters pussy.

After deleting the porn from Lisa's history, Bart picked the semen stained thong back up, he wondered whether she had anymore, pulling his jeans back up he opened the draws to find two more thongs, a black one and another red one. Bart thought to himself he would love to see Lisa wearing these. And suddenly an idea hit him. Bart put the clean thongs back and took the stained one with him as he ran out of his sister's room.

Bart ran into his room, he quickly dived under his bed to get his tool box leaving thong in its place. He chuckled to himself this was the only he had used this for something else them a prank. Bart went back into Lisa's room; he approached the wall that separated their rooms. From his tool box he pulled out a drill, on it was written property of Ned Flanders (like father like son). The wall was covered with rosettes for her science wins. Bart carefully moved one, using the drill he made a hole. After cleaning away the dust, Bart took his toolbox and left Lisa's room.

As soon as he entered his room, he shut the door, put down the toolbox and went to test his hole. The hole was just to right of his desk, which was perfect; if he wanted to hide the hole he could move the desk. Bart looked through the hole and for once he was pleased with his work, the hole was perfect, it blended in with the rosettes, and with a slight adjustment he could see perfectly into his sister's room.

His thought were interrupted by the phone, Bart got up and answered the phone "was up" , it was his mum "Bart i told you not to talk like that, anyway im taking the girls to see my sister we wont be back to late". After putting the phone down Bart swore, he would have to wait until tomorrow for his plan, after setting his alarm clock back, he went downstairs to spend the rest of the evening watching TV.
