Long live Slytherin
In an alternate reality where both Lord Voldemort and Harry Potter both died during their first meeting a great dark energy was released into the world and sought a new home.
It found that home within the newly born Draco Malfoy. He would not be aware of his great power for many years but when he did he sought to become a great and feared wizard just like Lord Voldemort.
However the muggle born Hermione Granger was always once step ahead of him to thwart his plans. She prevented the Chamber of Secrets from opening and stopped his meddling in the Triwizard tournament.
Unfortuately the one thing she couldn’t prove was his involvement in any of it so he remained a student at Hogwarts.
However now in their final year she was determined to get proof once and for all. She planned on doing this by using a spell she had found that would allow her to possess Draco’s girlfriend Evelyn. She was just as nasty and evil as he was so she knew his guard would be down around her.
She lured Evelyn to the girls bathroom and knocked her out. She looked at the spell in the dusty old diary she had found one morning walking the halls and performed it perfectly.
Her and Evelyn’s soul shot out of their respective bodies and into the other. Hermione traded her messy brown hair for smooth, silky, blonde mane. Gone were her dull brown eyes replaced with Evelyn’s piercingly blue pair. What she hadn’t anticipated was heaviness of her new breasts. They were so much bigger than her own, she couldn’t help but give them a pleasurable squeeze.
Another element she hadn’t considered were the intimate memories she now gained of Evelyn and Draco. Evelyn’s thoughts and desires quickly filled her head and although Hermione was a virgin she soon had the memories of an experienced slut and it felt good.

“Oh this little bitch sure looks and feels good, I feel so fucking nasty.” She said with a smirk admiring her new body. With the evil bitches memories flowing through her brain she found it hard to want to continue her plan. In fact all she wanted to do now was find and fuck Draco.
“I’ve wasted all my knowledge and years trying to stop Draco when I should of joined him. Now in this body I can help him become the dark lord and I will be his dark queen! Yesssss that sounds so much better. We will rule this pathetic school in no time and then rid this world of muggles and mudbloods.” She said with a cackle.
“And I know exactly who to start with.” She said turning around and levelling her wand at her former body. With a twisted smile she spoke the words “Aveda Kedava”.
Elsewhere in the castle Draco could feel the activation of the killing curse and knew his plan had succeeded. He knew a dork like Hermione couldn’t resist trying a new spell and his diary was the perfect temptation. Having the smartest girl in the school now be the hottest and most evil would allow him to win once and for all.
