Mind Blown!

Justin had been tinkering in his room for months on his invention leaving only for school and to occasionally eat and now he was finally putting  the finishing touches on his greatest invention ever a device to read minds finally he had his Eureka moment and had figured out where his invention ad gone wrong now with one final adjustment he was ready to test his invention.

"I'm a bloody genius with this I will be rich beyond my wildest dreams sure it may look like a normal VR headset but with this I can actually read minds the government will pay a fortune for this I just need to conduct a test to see if it works" Justin rubbed his hands with glee all those people who mocked him had called him a geek and a nerd would eat there words, the only question remained who to test it on first.

Justin didn't want to test it on a total stranger and he hadn't really got any friends so that narrowed it down immediate family not wanting to read his parents minds that left one person his Bitchy slut of a sister Evie.

Reading his sisters mind was not going to be a pleasant experience Justin hypothesised he was sure Evie's head was filled with nothing more than boys and other self centred thoughts it would be a nice first test as he figured his sisters mind wouldn't exactly be too difficult to read as there wasn't much activity going on in there so he set out to test his device at least he might finally know what if anything actually went on in his bitchy sisters head.

Justin found his sister where she always was in her room a typically slutty boudoir the smell of expensive perfume lingered in the air a vanity table sat in the corner covered with all sorts of expensive makeup like a typically vain teenage bitch Evie cared a great deal about her appearance  Evie was lying on her bed talking to one of her friends on her mobile phone this was the perfect chance to read her mind Justin could find out exactly what Evie thought of friend she was talking too perhaps it would give him some insight that could enable him to blackmail his bitch of a sister in the future this was going to be so fun.

The device was calibrated and Justin had a target, Evie now all that remained was to switch on the device and he would ,if his calculations were correct hear his sisters thought's his calculations however were slightly off as he was about to find out to his own cost.

It worked Justin could hear Evie's thoughts she felt nothing but contempt for her so called friend pretending to like her while scheming to fuck her boyfriend. Justin knew she was a bitch but this was more than even he had realised what a two faced scheming bitch here she was telling her best friend not to worry that her boyfriend was faithful  the time plotting to lure him into her bed the two faced cow Evie would pay dearly to keep this a secret Justin was certain of that.

Justin should have been satisfied with his successful test but he got greedy he imagined how many more secrets he could extract from his sisters mind so turned the power up and delved deeper into his sisters mind what he found there was a wellspring of filth Evie's mind was filled with slutty nasty thoughts many of which she had shared online with total strangers on twitter and on a blog. 

Evie liked the idea of corrupting other people to be as nasty and as spiteful as she was stealing her friends man was just the tip of a very bitcy iceberg but Justin had  gone too far down the rabbit hole these deliciously bitcy images were flooding his mind with noting in place to stop these thought's invading his mind his brain was overcome by a tsunami of Evie's wicked thoughts there was just too much bitchyness to be contained and with the device at maximum setting he had created a feedback loop Evie's thoughts were now invading and corrupting his mind. 

Justin's mind was breaking down  by Evie's thoughts a power surge shot though the device and sent these wicked thoughts deep inside  his body binding to his mitochondrial DNA and began to change him.

Somehow Evie's own twisted subconscious was effecting her brother her desire to transform and corrupt was now working on her brother on a genetic level changing him from a bother into a slutty bitchy sister inside his body his Y chromosomes were changing to X chromosomes.  

Evie was somehow altering his body chemistry she always wanted  a slutty sister and now she was connected to her brother on a genetic level she was going to have one Justin's body was no an extension of her will she was moulding his body into a bitchy sister with every thought she could feel her brothers feel and horror and his corruption which just drover her over the edge and made her cum hard.

"fuck I'm cummings to actually corrupt someone in real life its beyond anything I ever imaged its the greatest thrill ride ever your mind is a broken mess now but ill rebuild it sister" Evie said sinisterly at her broken shell of a brother.

Justin's body lay on the flow convulsing his mind now a broken mess of evil bitchyness his body was changing Evie's mind was sculpting him to be a younger slightly less slutty version of her she wasn't stupid she didn't want her sister to be hotter or more of a threat to her powerbase than her. 

Moulding her body Justine gained a new pussy and tits and long blonde hair she looked very much like Evie when she was done Evie admired her handy work then sent a photo to her best friends boyfriend inviting him around to get acquainted to her new Sister Justine they were going to have so much fun together.
