Arthur got to thinking about his little sister Zoey. She was annoying, and kinda a brat but...in a way, he thought it could be fun if he not only made her less bratty...but also make her amazing at the same time.
Grinning to himself he brought the Dictaphone to his lips.
"My little sister Zoey will be involved in an accident. She wont get hurt but the result of the accident will cause her to have random growth spurts that will make her Taller and curvier without any negative effects of growing too large. The growth spurts will start small, but each one gets more and more powerful. Every growth spurt will feel amazing to her, and leave her feeling horny. She will also begin having an incest fetish that she will find herself unable to resist the bigger she gets. She will only stop growing once I feel like she's gotten big enough and nothing can cure her growth until then."
He smiled to himself as the Dictaphone sparked, signaling reality shifting to reflect his wish. All of the sudden the phone rang and his mother answered it.
"Hello? oh my god! Is she ok?! ....she's what!?....h...how big? and her what...oh god...and it can continue to happen?!?....will they be able to reverse it?... oh god.... it just has to run through her system??"
She hung up the phone. Arthur approached his mother.
"Whats wrong mom?"
"Zoey...was in a bit of an accident...she's fine but... well you see..they were taking a field trip to the lab near town and they were learning of the things they were doing there... one experiment was being done with lasers in order to enlarge food and animals in order to provide more food before being consumed...and well your sister was horsing around with one of her friends and they fell into the deviice. It fired and hit your sister... and she's well...bigger now"
"Oh god...how big?"
"They said she measured 6 and a half feet tall... also...they said the machine was designed to also enhance certain parts of animals... and well... I guess you will see when Zoey gets home....also...they said there could be a residual charge in her system that could take days or even months to dissipate...and she might continue to grow..."
He could hardly believe it. It worked... Zoey was now bigger. Later on that day she arrived home after a barrage of tests were performed on her with a promise to return for some future testing. You're eyes widened at the sight of her walking through the door. She was 6'6 and had large DD cup breasts when she had none before, her hips and butt were bigger too. She was given clothes by the lab.
"I can't believe my baby girl is like this..."
"Awww mom don't worry! I kinda like it! I mean look how big I am. I can reach things now. Plus boobies kinda feel nice."
"Zoey! don't talk that way infront of your brother! be more lady like!"
Zoey looked incredible. She looked like she had skipped through puberty to the good parts. She looked 18 years old now. Standing nearly 7 inches taller than you now, she was a sight to behold. She annoyed you by wanting to be close to you and play video games with you all the time but with a body like this...and her new desires...You definitely would not mind spending more time with her.
"Hey Arthur! Look at me! im really big now!"
"Yeah...yes you are Zoey"
"You wanna play some video games in your room together?"
"Sure Zo. Lets go"
Arthur watched as Zoey went up the stairs, unable to keep his eyes off her ass as it moved in her shorts. They were so tight around her new ass they look painted on. He Thought to himself -
~ Dear god... I hope she has a growth spurt soon... I wanna see her growing~
They soon arrived in his room and she took her usual spot on the pillow on the floor.
She picked up her pink controller her parents bought for her when you two played games
"Wow, this feels so small in my hands now. Being big really is weird"
"H...How did it feel Zoey? You know...to grow"
"Well... It felt...good actually. I mean... Really really good. I felt tingly all over and then I saw my boobies growing on my chest, and my clothes started to get really tight. Then I could feel my butt getting bigger in my jeans then it hurt for a second as my jeans got really tight on me but soon as they ripped...it felt really really good. Soon I was standing naked infront of my class...but everyone was so short! Even the teachers!"
"So you like being big?"
"Like it? I LOVE IT! Infact... I hope I get even....oh....ohhh wow...."
"Zoey?"
She started to moan. She reached up and grabbed her breasts infront of Arthur, and started to play with them. He soon realized why...she was horny...cause she was starting to grow. She let go of her breasts as they swelled in front of his eyes to a G cup in size. The shorts she was stuffed in ripped open behind her as the button holding them shut flew across the room. She then began to grow taller....and taller. Arthur watched slack jawed as his 6 and a half foot sister grew and grow infront of him into a 7 foot tall goddess with G cup breasts, and an ass that any girl would kill to own.
"Wo...Wow that felt so good...oooh im naked again... um...you don't mind if I play naked for a little while Arthur? I don't think any clothes in the house will fit me and if mom and dad find out they might not let me play with you"
He could hardly believe it...she was comfortable being naked around him. Before the idea of her naked would repulse Arthur but now that she had these curves...and a growing incest complex, it was such a turn on.
"S...Sure Zoey....anything you want...you're the bigger one here after all"
"mmm....yes....Yes I am! I'm the big sister now...and I think that was only the start Arthur...I think I'm going to keep getting bigger...and bigger. I love it!"
She then hugged Him. Arthur's face pressed into her firm, large breasts before she let him go and proceeded to play video games along side him.
