Hermione Granger, the brightest witch of her age, had returned to Hogwarts to complete her seventh year of study and her NEWT examinations. She wasn't alone; many of the surviving students from her year had returned, first to help repair their beloved castle and then again as "eighth-year" students. Fortunately, none of her old friends had passed away in the battle: Fred had almost died, but Percy had pushed him out of the way of the falling wall just in time, leaving the twin with nothing but a few rugged scratches. Amazingly, the death of Voldemort and his followers had even led to the return of Sirius Black from beyond the veil, which had been a piece of Dark Magic tied to Voldemort and had been effectively destroyed with its master's downfall.

Castle reparations had been fairly straightforward, given that the entire castle had been effectively destroyed. Hermione had helped Professor Flitwick to lead a team to cast Charms to fix much of the damage. She was certainly grateful that she had been able to participate in the restoration of the most wonderful building in the world. There had been something immensely satisfying to Hermione about feeling the magic coursing through her veins, and watching it shoot out from her wand to restore the stones which made Hogwarts' foundation. The building had always held special significance to Hermione, and the chance to be part of the team who rebuilt Hogwarts was a deep honor.

Now, Hermione was back again during the September of her eighth year. Of course, there were changes that had been made. Professor McGonagall had taken the post of Headmistress, and she also would be teaching Transfiguration until an appropriate replacement could be found. Professor Slughorn had returned as Potions Master. Dawlish had been hired to take on the post of Defense Against the Dark Arts. For once, there would be no threat of Death Eaters in Hogwarts, and Hermione would be able to focus on what matters most: learning.

The eighth years had been located in temporary housing near the Room of Requirement. Although they would be taking classes with the rest of the seventh years, there was no room in the dormitories for an entire extra year of students. This housing situation was unique in that the eighth years, though remaining inextricably part of their own houses, all lived together. Admittedly, one perk of the reconstruction of Hogwarts was that the future eighth years had been able to design their own housing, and Hermione had taken the helm of that project. A large, comfortable common room was located at the center, complete with squishy armchairs and large mahogany desks. Hermione salivated a little at the thought. In addition, because they were studying for NEWT's, the eighth year dorm gave each student his or her own single room and bathroom. Because of her role in the rebuilding of the dorms, Hermione had taken the liberty of adding her own personal study to her room. Finally, she had an adequate amount of bookshelf space for all of her belongings! She personalized her room in other ways too—the large plush four-poster was covered with scarlet and gold sheets and comforters, and there were pictures framed along the top of the dresser. Some of them moved, showing Harry, Ron, and Ginny, and the Muggle pictures featured her parents' loving smiles.

Moving back into her study, Hermione sat down and got to work. Opening her potions textbook, Hermione got to work on her homework, brewing a variation of Amortentia. She stirred and mixed the ingredients, adding rose pedals and peppermint liberally while stirring. She reached for the powdered Moonstone, and began to sift out the correct amount when she head a BAM! and Ron Weasley, her boyfriend of three months, jumped into her study.

The shock of his sudden arrival caused her hand to slip, pouring so much powdered Moonstone that the potion began to froth and bubble viciously. Ron lunged at Hermione, attempting to wrap her in a hug, but instead caused her to slip and fall into the Cauldron!

A massive cloud of pink, sultry steam filled the room, and Ron whiffed Fizzing Whizzbees, Hermione's hair, and Bludger grease. He hopped to his feet, and held out his hand to Hermione to pull her up from the cauldron. "Sorry, love!" he said.

A very different Hermione emerged from the cauldron than had fallen in. It seemed that the additional Moonstone, combined with her full-body immersion into the solution, had changed her into something of a sexpot! Her breasts had swelled at least two cup sizes—Ron reckoned that she had to be a 32DD! Her ass had likewise rounded into an extremely appealing curvy shape. Most shocking of all, her clothes had dissolved, and she was completely naked. Ron had never been more attracted to her, and it turns out the feeling was mutual.

"FUCK ME, RON!," Hermione yelled.

Ron was shocked; he and Hermione had of course slept together before, but she had always insisted on extremely vanilla sex, and preferred to call it love-making. Not once had he heard her utter the word "fuck" as it related to sex.

Ron was of course happy to oblige, and lowered his mouth to hers for a passionate kiss. Already, though, Hermione was unbuttoning his pants and kneeling down to take his fully erect 7-inch cock into her mouth. Her hot mouth surrounded his cock, deep-throating him. This too was unusual, Ron thought, because Hermione had always refused oral sex before. Ron was, quite simply put, in heaven. Hermione too was enjoying herself, slurping on his hot cock with all the vigor she usually put into telling off Fred and George for experimenting on first-years. Ron had never felt so good, and Hermione felt the same. She couldn't believe that she had resisted Ron's requests for blowjobs for so long. She thought that she could suck him off forever, until he grunted and came in her mouth, great wads of sticky, delicious cum. Hermione swallowed every drop, hungry for it in a primal way she hadn't known possible.

Ron's still-erect cock stood at attention as Hermione's mouth left it. Her hands pushed him to the floor and she straddled him in one swift motion. Her wet pussy enveloped his cock, as she began to ride him with immense vigor, moaning and screaming his name. Hermione's tits bounced up and down as her naked body rocked happily over his. There was nothing Ron could do but let Hermione take control. This time Ron lasted much longer, and Hermione had five orgasms before Ron spilled his seed into her.

"FUCK, RON!" she yelled as she felt his hot cum shooting at her inner walls. The sensation was enough to send her over the edge again, her sixth orgasm in a half an hour.

Climbing off of his cock, Hermione smiled at Ron and said "Ron, I love you, but I need far more sex than you can give me. When you surprised me, I poured far too much Moonstone powder into the cauldron, altering the potion from Amortentia into what is often referred to Nympho Potion. When you pushed me into it, it soaked every one of the cells in my body, fundamentally altering them. You've changed me into a Nympho, and there will be no going back."

With that, she left to go find another cock to impale herself upon.
