“Ginny, wake up!” Hermione hissed.

She knelt beside Ginny’s bed, desperately trying not to attract the attention of the other sleeping girls in the Gryffindor dormitory.

Ginny opened her eyes slowly, but shot up in bed — suddenly wide awake — at the sight of Hermione. The vision that greeted her was completely unlike the Hermione she knew: Hermione’s previously modest-sized breasts had ballooned out to at least double-Ds … and Ginny was getting quite an eyeful of them, as Hermione was now only wearing only a skimpy, bubblegum-pink string-bikini-top composed of little more than two tiny triangles slightly smaller than her areolas.

Aside from her incredible cleavage, Hermione’s nipples were also standing hard and proud — at least an inch long, pierced with huge golden rings — and Ginny could see them clearly poking through the thin fabric of the bikini top. Ginny’s gaze traveled down Hermione’s tight body, taking in her exposed tummy before reaching her pussy: her hairless, juicy, obscenely-dripping fuckhole was covered only by a minuscule white thong barely capable of covering her massive clit and a single meaty cunt-lip.

Ginny looked down further, eyeing Hermione’s long, smooth legs and bare feet encased in tight, white fishnet stockings.

Finally looking at Hermione’s face properly, Ginny saw that she was wearing a truly whore-ish amount of makeup, done up like a pornstar on her way to a photoshoot, and that Hermione's previously bushy hair now cascaded down her back in a waterfall of shiny curls.

Hermione, in short, looked like a hardcore preteen cam-whore out of Ginny’s wet dreams … and Ginny rapidly felt her cunt start to moisten just looking at her.

“Holy shit, Hermione, what happened to you?” gasped Ginny, a little too loudly for Hermione’s comfort.

“Quiet!” hissed Hermione again, climbing into Ginny’s four-post bed and drawing the curtains to give them some privacy.

Suddenly crammed so near her transformed friend — close enough to smell the girl’s sweat — Ginny started to get seriously aroused: she’d always had a thing for Hermione, and having this ultra-sexual version in her bed set her mind racing. She was naked under her covers, of course, and now she started slowly slipping a hand down between her legs.

She couldn’t help herself.

It was like a dream come true.

“Ginny, I’m in REAL trouble, and you’re the only one I can talk to about it. You’ve got to help me!” Hermione said, positioning herself at the foot of the bed.

“Trouble?” asked Ginny, biting her lip with a little smile. “What sort of trouble?”

Hermione frowned. “Isn’t it obvious?” said, gesturing down at her body. “I’ve been cursed!”

Ginny took the opportunity to get another long look at her friend’s generous new assets.

Ginny smirked. “Hermione, if there’s a ‘curse’ to make a bitch look as sexy as THAT, where can I sign up?”

Hermione blushed, both at Ginny’s coarse language and her crude (sort-of) compliment. “Listen,” she said, sliding something across the bed to Ginny. “I found this book in the library this afternoon. When I picked it up, I felt … strange.”

“Hmm,” Ginny said, reaching out with her free hand to examine the book … while her other hand was now merrily inserting two fingers into her dripping hole.

“Be careful!” Hermione cried.

The moment Ginny touched the book, she felt a powerful sexual charge flow up her arm and down to her hard nipples.

And to her clit.

Ginny added a third finger, barely stifling a moan; she couldn’t read the writing on the cover, but she felt mesmerized by the strange, swirling patterns that covered the book: they seemed to fill her mind with ideas of sexual acts and perversions she had never considered before.

“It’s a book of sex magic,” said Hermione, too flustered to notice Ginny’s physical reactions. “I looked through part of it, and there are some REALLY weird spells in there. But there’s one that said it would make the subject irresistible to men! And I thought - well, I thought ...”

Hermione trailed off, too embarrassed to continue.

Ginny rolled her eyes.

“You thought you’d use the spell to finally get some hard Weasley cock in you,” Ginny finished. She had the book open, and was slowly flipping through the pages: taking in the names of spells and the drawings of their effects eagerly.

Hermione gasped again. “Ginny! What’s gotten into you? I know you’re more … uh, ‘experienced’ than I am, but you’re never normally so vulgar!”

‘More experienced’ was a bit of an understatement …especially considering Hermione’s virginal status.

Since starting at Hogwarts the year before, Ginny had fucked half the Gryffindor boys, as many girls as she could seduce, dozens of students from the other houses (including several Slytherin boys who had “raped” her after she had pretended to pass out drunk outside their common room), two teachers — one for an improved grade, and the other just to see if she could — and, on one VERY memorable occasion, Hagrid’s dog Fang.

She had shared tales of some of these exploits with Hermione, but knew that her best friend was too uptight to really appreciate just how good the slut
life was.

She had definitely kept the teacher-fucking (and the dog-fucking)quiet.

“Well,” said Ginny, “you have to admit, this is a vulgar situation! A super-hot, slutty-looking version of my best friend has just climbed into my bed and handed me a book of sex-magic she tried to use to seduce my brother! Honestly? I’m having trouble not just throwing myself at you! Now finish your fucking story!”

Ginny had, at this point, gotten her entire hand up her soaking tunnel and was fisting herself casually. A loose fuckhole was the one bad thing about being a slut, she often thought … still, there were advantages.

Hermione took a deep breath before continuing. She saw Ginny’s point.

… also, her own vagina was starting to moisten despite herself. Without noticing, she began to match Ginny’s fuck-rhythm: rubbing her pussy through her thong.

“Alright,” she said. “I thought that the spell might finally make Ron sit up and take notice that I’m a girl. God, I’ve been so horny! So … so I cast the spell, right there in the library! And it turned me into this … this slut!”

Ginny began fucking herself harder.

Hermione suddenly burst into tears, leaving streaks in her caked-on whore makeup. “My breasts grew huge, the little bit of body hair I had vanished, and I got all these … CURVES all over! Then my hair got all soft and long, and all this makeup appeared on my face!”

Ginny had limited sympathy. “Still not seeing this as a ‘curse’, babe. Didn’t you want the spell to make you sexy? And it looks like you’re dressed to show off the new body.”

“You don’t get it!” wailed Hermione, gesturing at her skimpy lingerie. “That — THIS — is part of the spell! These used to be my favorite pajamas, the ones with the pattern of kitties on them! The spell seems to transfigure any clothes I put on into something only the most vulgar prostitute would wear!”

Ginny had a sudden mental image of a skanky Hermione working a street corner in a tube top and miniskirt. She almost came at the idea.

Hermione continued, oblivious, tears still streaming down her face. “In the library, the spell turned my Hogwarts uniform into a slutty schoolgirl outfit! Plaid microskirt, tiny thong, shirt tied under my breasts, the whole shameful costume! It even pulled my hair into pigtails! And that’s not even the worst bit!”

Ginny could sense where this was going … or, perhaps, hoped she could. She could also sense her orgasm approaching. She just needed to hear the climax of Hermione’s story.

“You know how the spell said it would make the subject irresistible to men?" said Hermione. "Well, it wasn't just talking about making me look like a slut. It's done something to the boys as well. There were three guys in the library -- older boys, all Gryffindors -- and as soon as I cast the spell, they all came over and started grabbing me, all over. They called me things, said horrible things ..."

"What did they call you?" moaned Ginny, her eyes closed. She could picture the scene in her mind. She bit her lip. So close...

"They called me a whore, a slut, a fuckhole, a jizz-toilet, a cock-sleeve. They said I was just mudblood cuntmeat, a dick-licker, a stupid bitch with fat tits and loose holes; they said I was only good for sticking their dicks into and taking their cum. They called me a worthless cum-bucket, a human toilet. They said lots of other stuff as well, like that they were going to fist my holes inside out and put the video on the internet, or slice off my clit and mail it to my mother, or sell me to a nigger rape-brothel, or break both my arms and and legs and chain me in the bathroom as a piss-drinking sex-toy."

Hermione's litany of abuse made Ginny moan again.

The filthy words were turning Hermione on as well, despite herself. "One of them pulled my breasts out of my top and started groping them quite painfully. He kept pinching my nipples until they were rock hard. Another one flipped up my skirt and grabbed my ass. The third guy, he stuck his fingers up my, m-my..."

"Your pussy? Your cunt? Your sloppy fuckhole?" said Ginny, egging her best friend on. Her eyes were still closed, her fist now pumping wildly at her hole, not even trying to hide it. Only Hermione's tearful distress (and terrified confusion over her own incredible arousal) prevented her from consciously seeing what Ginny was doing. The smell of wet pussy filled the room now, causing Ginny's roommates to shift in their sleep, their dreams filled with hard cocks forcing open little cunts.

"Yes," Hermione groaned. "He jammed his thick fingers up my sloppy little fuckhole."

Ginny worked two fingers of her other hand into her asshole.

Hermione shivered at the words coming out of her mouth. "He pushed in and out, over and over, so hard and so deep, and he played with my clit; I couldn't stop myself getting wet. God, I got SO wet; more than I ever have in my life: I was dripping! When he noticed, h-he just laughed. He said 'the stupid little cum slut is begging to get raped'. A-and at that point, Ginny? I almost agreed with him. I think I moaned ... then he bent me over a table, pushed my thong to the side and stuck his cock in me. I was a virgin! He raped my virginity away and I still don't know his name!"

Hermione was crying at full force now, but her dripping cunt was telling a different story. "His friends took turns fucking my mouth. They grabbed my pigtails and drove deep into my throat -- I gagged, I couldn't breathe, and they laughed! They held my head down on their filthy cocks until I almost passed out! I think one of them slapped me awake before he released my mouth."

Ginny groaned again. This was bringing back fond memories of her many 'rapes'.

Hermione continued, her story gushing out of her now, unable to stop. "I thought they were going to cum over my face like in the porn you showed me, but the guy raping my pussy had a better idea. He said 'I bet the dumb whore's not on birth control, we should knock this cunt up.' I cried out and begged for him to pull out, but he just laughed, ripped off my thong and shoved it in my mouth to gag me. One of his friends even fucked the thong down my throat to make sure I couldn't talk. I was choking and gagging when my rapist pushed his cock all the way in to my cunt and came. It felt like it was shooting in to my womb -- and, Ginny... the worst part? The worst part is ... I came as well."

This was the last straw for Ginny: hearing her friend, her sweet, innocent, virginal friend describe cumming on her rapist's cock as it knocked her up was more than her wildest dreams. She came, hard, squirting her fuck-juices all over her hand and bed. Her fist was trapped in her spasming pussy and her head thrashed on the pillow as she let out a steady whine of pleasure. Hermione finally realized what her friend was doing, but found -- to her surprise -- that she wasn't angry.

She was just more turned on.

Her experiences, her story, had driven her slut of a best friend to a mind-shattering orgasm ... and that suddenly made her feel like it wasn't so bad. In fact, it was the best thing that had ever happened to her.

Hermione slipped her fingers to her own pussy. She couldn't help indulging her newly found lust for degradation.

She wanted to finish her story.

"My rapist pulled out. I could feel his spunk dripping out of my cunt before one of his friends replaced him. He had already fucked my throat REALLY hard, so I knew he wouldn't last long. My rapist moved to my face and said it was my duty as a cum-toilet to clean him off, then he stuck his still hard cock in my mouth. I could taste both of our juices on him. His friend came inside me as well. I felt stuffed with cum.

“He pulled out and forcefully used one of my pigtails to clean his dick. The third guy started complaining about my sloppy pussy, said he didn't want to fuck such a loose whore cunt. But he said he still wanted a chance to be my baby-daddy, so he held my cuntlips open and just put the tip of his cock to them. He jerked himself off into my cunt!

“My first rapist had worked his way to facefucking me again by now. It was a good thing my thong was so tiny, or else I would have choked on it. He came down my throat as the third guy shot his load up my hole. They both pulled out, and the leader stuck two fingers down my throat to extract my thong. It was covered in spit and his cum. He started smearing it over my face as I started to cry.

“I told them that I wasn't on birth control and they had probably knocked me up. I said I was too young to get pregnant! He just laughed again and said that he had an idea. All it would take to stop me getting knocked up, he said, was to clean out the sperm from my cunt. He said he knew just the way … before he went behind me again, stuck his cock up my cunt and started pissing!"

Ginny had been half listening since her orgasm, fingers lazily stroking in and out of her fuckholes, but she snapped to attention at this. Of course, she had been pissed on several times: it was one of the many things a good fuckslut like herself did without question. She had even drunk her own pee at the request of a perverted Hufflepuff or two. Or three. But she had never had someone piss up her cunt before. She felt a twinge of jealousy and made a mental note to try it as soon as possible.

"He pissed for so long," Hermione continued,rubbing herself openly and without shame. "It was warm and it
filled my womb. I could feel piss and spunk running down my legs. Eventually, he stopped, but the other two quickly took his place. I guess the third guy got over his distaste for whore cunts. While the third guy was pissing, I looked down my body and could see my belly swelling from the
amount of piss inside me. I looked a little pregnant! It was the most degrading thing that has ever happened to me. I actually came again at the image...

So did Ginny.

“After the third guy pulled out,” Hermione said, “the leader took my disgusting thong and pushed it as far up my pussy as he could, blocking in the piss. They
let me stand up, my piss and cum covered legs were shaking, and said that I had better not take the thong out for at least an hour. They said they would see me around, slapped my ass and tits, and left. I sat there, stunned for a few minutes, before I realized what condition I was in and ran to the girls’ bathroom. Thankfully, no one was in there. I saw my condition in the mirror: my face was covered in makeup smeared by spit and cum; my hair was wild, one pigtail also matted with cum and pussy juices. My tits were on display over my top, covered in spit that had dripped from my face. My belly was swollen and pregnant-looking with piss. And my legs were covered in the piss and cum of three men. I hid in a stall and tried to clean myself up. I didn’t even consider disobeying their orders, so I waited an hour before pulling out the thong. When I did, a flood of piss and cum shot out of me and into the toilet. I knew I had to avoid being seen, so I waited in the toilet stall for hours until I knew it was late. I fixed up my clothes, and was about to leave when I realized I still wasn’t wearing panties. I’d never gone without them before, so I braced myself and pulled on the pissy and cummy thong. It squished and buried itself inside my slit. I snuck up to my dorm and changed to my pyjamas, but they transfigured into this bunch of slutwear. So … I- I came to find you.”

Hermione was panting as she finished her story. It was bizarre: today she had been cursed, lost her virginity in a gang rape, degraded repeatedly, and finally had her cunt used as a urinal, but right now she was most frustrated by her inability to make herself cum! Her fingers were working furiously at her dripping hole, but she just couldn’t finish.

She heard a coughing noise, and opened her eyes.

She hadn’t even realized that she had closed them in her reverie. Ginny was sitting on top of the covers, naked and beautiful, with the book in one hand and her wand in the other. She was grinning.

“Sounds like you’ve had an exciting day then, my newly slutty besty,” Ginny said, licking her lips. “I’ve had a quick look at the spell you used and it seems like you’re fucked again, as there doesn't seem to be a way to reverse it. Looks like you’re gonna become something of a school fucktoy!”

Ginny flashed another dazzling smile as Hermione groaned, half in dismay and half in pleasure at the
thought of being raped by any man who saw her.

“Unless,” said Ginny, slyly.

Hermione looked at her, pleading.

“Unless you take charge,” Ginny said. “Unless you control when the men fuck you. That way, you would have the power.”

Hermione shuddered again. She didn’t want to admit just how much she had ENJOYED her submissive, degrading rape. At the same time, having more control over her fucking would hopefully prevent her from being constantly bent over and penetrated in the corridors of Hogwarts.

“Can we do that?” Hermione begged. “Please?”

Ginny nodded, smiling again. She could always reverse what she was about to do if she ever wanted the old, weak, submissive Hermione back. “I’ve found just the spell,” she said, pointing her wand.
