This story is AU, obviously. It's more Porn w/o Plot but you can find some vague plot in the story if you search hard enough. Actually, I know it doesn't seem so, but this story does have a plot, strange though it may seems, it'll just take a while to get there, especially since Hailey won't join the Wizarding World for a little while yet. Let's just say that these chapters serve as a way to show exactly how Hailey is as a character so that the (at-a-slow-pace) change in her will be more evident as the story continues.

BTW I imagine a young Megan Fox as Hailey - but with larger breasts.

HAILEY POTTER THE COCK SLUT

Summary: Petunia and Vernon Dursley never married and they never had Dudley. Petunia has always wanted a child, a girl specifically, so when she finds Hailey Potter on her doorstep, the night of Halloween 2001, she's ecstatic.

Petunia has never been pretty like her sister Lily and she has always found it difficult to have men interested in her. All the guys she had dated had left her when they had realized that she wouldn't have sex with them before being married. Because of this experience, Petunia has convinced herself that the only way to gain men's interest is to always be willing and eager to have sex with them. Petunia teaches this to Hailey because she doesn't want 'her little girl' to become a spinster like her.

Hailey - following Petunia's advice - loses her virginity at 13. She soon becomes addicted to sex, willing to spread her legs for anyone who has a cock and that can give her an orgasm.

When the Hogwarts letter arrives, bringing with it an enormous change in her life, Hailey is thrown into a very strange world where everybody there knows her name and has very set ideas on how she should be and how she should behave. They expect her to be the hero but all she has ever known is how to be a slut.

At Hogwarts she will learn not only magic but also that she can use sex to her advantage.

For the sake of this story, the Hogwarts Letter arrives at 14 years old, not 11.

IN THIS STORY LITTLE WHINGING IS A LONDON DISTRICT.

Main Pairing: FemHarry/Severus but in general FemHarry/Multi.

Disclaimer: I'm not J. K. Rowling, ergo I don't own Harry Potter. I don't gain any money for writing this. I'm writing it just for fun.

Just one more thing, I changed the story setting from the nineties to the 2010's. So Hailey is born in 2000, not 1980.

Be aware that I'll erase every flame disguised as comment. This story is not a serious one, I'm not writing it because I approve of sex with a minor nor I am some kind of pervert or pedophile or whatever. This is fiction, it's not real. If some people writes about rape, it doesn't mean that they are rapist or they approve of rape. The good thing about fiction is that you can make do your characters whatever you want because they are NOT REAL. So, don't try to censure my work because I won't listen.

Prologue

31st October 2001 - 4 Private Drive, Little Whinging, London - Petunia Evan's Residence

Petunia heard the crying first. It was the middle of the night and she wondered what was all this noise. She cautiously went towards the door and heard it again. It was the unmistakable sound of a baby wailing at the top of their lungs. For a second she wondered if she was dreaming but then she shook her head and opened the door. There, on her house's doorstep, there was a baby bundled up in a red blanket. She peered at it curiously and almost gasped in surprise when she noticed the baby's eyes. They were green like her sister Lily's were. She noticed soon after the letter half poking from the blanket and recognized immediately the handwriting, Albus Dumbledore's, Headmaster of Hogwarts School of Witchcraft and Wizardry. She realized what had happened then, her sister was dead and this was her daughter. Petunia and Lily weren't close by any stretch of the imagination but she had been invited to her sister's wedding and she had been with her in the hospital when Lily had given birth to Hailey Potter. Though she was a muggle, her sister Lily had kept her on the loop about the happenings in the Wizarding World and she was well aware of the threat the Dark Wizard Lord Voldemort posed to the entire World, not only to the Wizarding one. And she knew that her sister and her sister's husband were part of a group that fought against him, thing that put them and their daughter in extreme danger. Petunia had promised Lily that, in case of Lily's death, Petunia would take care of the baby like she was hers. Not that that promise had been difficult to make, Petunia had always wanted a child, a daughter particularly, but unfortunately she had never found a man interested enough in her to marry her.

Petunia picked the baby up from the ground and smiled at her, humming a lullaby. She didn't remember the last time she had been so happy. This baby girl was hers now and Petunia would give her everything she would ever need and she would teach Hailey not to make the same mistakes she herself had made concerning men. She didn't want her daughter to end up an old spinster without a husband or a child. If she had anything to say about it, Hailey would become very popular with men, especially if she had inherit Lily's beauty.

Chapter 1

3rd June 2006 - 4 Privet Drive, Living Room

"Is that a penis, mom?" Hailey asked Petunia, watching in fascination the pictures her mother was showing her.

"Yes, honey. And this" Petunia answered, showing her another picture "Is the vagina".

"But it's different from mine mom. It's very hairy. Why is that?"

"It's because this vagina belongs to a woman who has hit puberty".

"You mean, when women develop breasts and such?" Hailey asked, her gaze fixed on the photo in her hands.

"Yes, honey" Petunia said with a smile.

"But I don't want my vagina to be this hairy. It's ugly" Hailey said with a pout.

"Don't worry honey, as soon as you start develop hair down there, you'll do the Hollywood wax that will remove all your pubic hair. Men don't like pubic hair".

"Yes mom" Hailey nodded, smiling once again.

"Now, repeat what I told you. What you have to do to have men interested in you?"

"Always be willing and eager for sex. Men don't like women who don't have sex. Oh, and my clothes need to scream 'ready for sex' too or it would be pointless". Hailey repeated obediently.

"Very good honey" Petunia nodded approvingly.

10th August 2007 - Hailey's Bedroom, 4 Privet Drive

Hailey was lying on her bed, bored out of her mind and browsing through a gossip magazine absentmindedly until she noticed a picture of a model, of about 14 years old, wearing a bikini. The model's face was not particularly beautiful - in fact Hailey was much more beautiful than her - but her body was slender and perfect and not at all flat-chested like most models were. Actually, for having fourteen years old, she had kind of big boobs. Hailey observed enviously every detail of the model's body and wondered when she was finally going to start developing. She wanted to have breasts - big breasts would be ideal - and turned men's heads. But for now, she had the body of a baby and it seemed like she was not going to develop anytime soon. Her mom had told her that usually a girl started to develop between 9 and 12 years old and before 9 was extremely rare. Well, she wanted to be one of those extremely rare cases, she didn't want to wait another two years - or god forbid even more than that - before becoming a woman. She wanted to start developing breasts now! A moment later, she felt a tingle of pain on both her nipples and winced. What had happened? She touched first one and then the other with some amazement. She could feel some kind of small, hard sphere inside, the tell-tale sign that she was starting to develop breasts. She smiled elated. She didn't know how it was possible but she had just willed her body to start puberty and her body had answered her.

6th May 2011 - Hailey's Bedroom, 4 Privet Drive

Hailey woke up that Monday morning with painful belly cramps and something warm and sticky wetting her knickers.

She pushed aside the blankets that were covering her body and immediately noticed the red stain on the sheets. She smiled, realizing what had happened.

"Mom!" She shouted at the top of her lungs.

Her mother entered her room a few seconds later and understood immediately why Hailey had called for her.

"Oh, my baby girl all grown up!" Petunia said with a big smile before encasing her daughter in a strong embrace.

"I don't want to go to school today mom!" Hailey said with a pout.

"Of course not, honey. We are going to the gynecologist today to prescribe you the pill. You're a woman now and we have to think about protection. Safe sex is very important".

"Yes, mom".

31st July 2013 - 4 Privet Drive

Hailey woke up to the smell of breakfast and smiled. Today was her thirteenth birthday and her mother had organized a party for her for that evening.

She looked at the clock and groaned, it was six thirty. She was late for her usual morning training. Since she was five, her mother had hired a personal trainer for her, so that 'her body could be modeled into the perfect shape', so that growing up, continuing to follow the regime her mother had created for her, she would never had to worry about cellulite, or body fat of any kind. The daily workout plus the special diet she was forced to follow, was the perfect combination to render her body a 'work of art' - her mother's words, not hers -. Not that Petunia really thought she would ever run the risk of going fat. Hailey was naturally slim with long legs and her mother said that if she ever decided to be a model, she would have the perfect body for it.

Her mother had instilled in her, since the moment she could understand it, the importance of being hot and sexy. Men thought about sex almost 24 hours a day and they wanted women who 'screamed' sex while looking at them. In other words, Hailey needed to become every men's wet dream and no man would ever want her if she had body fat or cellulite.

Hailey shook her head and stretched her arms over her head before getting up and taking a shower quickly. As soon as she was finished, she covered her lightning bolt scar with a layer of foundation like her mother had taught her, she put her long, slightly curly hair in a ponytail and began getting dressed. She chose the usual outfit for a work-out, black mini boy-shorts and a black gym bra. She didn't wear knickers since the shorts were too tight.

She didn't usually wear bras under her clothes because she thought it was pointless but while doing physical activities she was forced to wear them because it would be uncomfortable otherwise. Her breasts were as big as oranges now, especially visible in the bra she was wearing - and they were still growing. She felt very grown-up because of that. Some of her friends had started to develop breasts just now and she had started puberty when she was 7. She was also pretty tall for her age, 5 feet 5, and that helped to give the impression that she was older than what she actually was.

When her mother had first found out that she had started to develop, she brought Hailey to a specialist to make sure that nothing was wrong. The doctor had been kind of baffled that a 7 years old had started puberty but she had said that since she was actually developing slowly, it was not really dangerous. The only real consequence would be that she would become a woman much earlier than her peers. But she wouldn't run the risk of aging abnormally fast or anything like that. Once her body would stop developing, she would start to age at the normal rate. So no problem there.

She looked at herself in the mirror and decided that she would wear a little make up today. Her gym instructor was young - 18 years old - and cute and she had wanted to kiss him since the first time she had met him. Today she would transform that desire into reality. After all, her mother always said that willing girls always obtained whatever man they wanted, especially if they were beautiful like her.

She put a little bit of clear lip-gloss to emphasize her naturally plump lips. Then she put on a little bit of mascara, this time to emphasize her big, green eyes. She took another long look at herself in the mirror and smiled. Yes, she was perfect.

She went downstairs towards the dining room where breakfast was already on the table, she kissed her mother on the cheek as a good morning and ate her usual: a cup of tea, 4 biscuits, a glass of orange juice and two slices of toasted bread with jam. Once breakfast was ready she went outside where her instructor was already waiting.

Nick was wearing light grey sweatpants and a black t-shirt that morning that didn't serve at all to hide the muscles underneath. His light brown hair, slightly long, were mussed by the light summer breeze and his blue eyes shined in the sunlight. Hailey admired him openly and Nick winked at her when he noticed.

"Hi Nick." She greeted him with a flirtatious smile. Nick smiled back at her before telling her to start running. Hailey pouted back at him before complying. They usually ran outside in the summer since the weather was pleasant at this time of year.

She ran for over twenty minutes, her breasts bobbing up and down with every step and she noticed with satisfaction that Nick was definitely looking. She decided that this was as good moment as any and she faked a strain, tumbling to the ground. Like she wanted and was expecting, Nick was immediately upon her, asking what was wrong.

"My ankle. I think I sprained it. Ouch, it hurts." She was so good at faking that she was even able to shed a few tears. Nick took her into his strong arms and brought her to one of the benches scattered all over the park. He took her ankle in his hand and started to move it. Hailey grimaced and told him to stop. "Please, I'll be fine. I just need a minute." She said before adding. "Come sit near me." Nick hesitated a little before doing as she asked. Once he was seated next to her, she put her head on his shoulder in a casual gesture and sighed. "It's peaceful, isn't it? Being outside like this. It seems like we're the only two people left in the world."

Nick agreed with her but didn't add anything else. Hailey, tired of the silence and starting to become a little impatient, moved her head towards his until she was looking into his eyes. She hesitated a moment and then she moved forward to kiss him. Nick started to kiss her back after a few long seconds of stillness so she opened her mouth to kiss him properly. She had seen movies and had asked her mother about it so she knew there were supposed to be tongues involved in it. She clashed her tongue against his and Nick pulled her closer to him. Hailey immediately sat astride him, directly on his lap and started moving her hips against him. She felt Nick moaning in her mouth while he started to harden against her. She wanted to come but she especially wanted for him to come just by rubbing against each other like she had seen sometimes in the movies. She was so wet and aroused already that she knew it wouldn't take long for her to come but she wanted Nick to come in his pants first.

She smirked before bringing Nick's hands on her hips as a way to help her movements. Nick didn't seem to mind at all, enthusiastically using her body to come. She felt him kiss and nibble her nipples over the bra causing waves of pleasure to go straight to her clit.

A few movements of her hips later and she felt him going rigid against her before grunting loudly in pleasure, a wet, warm, sticky spot in his pants, the telltale sign that he had reached his release.

Hailey brought her fingers inside her shorts and started rubbing against her clit, desperate to come now. She moaned loudly before feeling Nick's fingers joining hers. He inserted two fingers inside her and she screamed, the orgasm hitting her almost suddenly.

After a few long, deep breaths she had taken back control of herself and left his lap. Nick smiled at her, kissing her sweetly before asking her "How is your ankle? Still hurting?"

"It never did hurt in the first place" She replied with a wink "It was just a way for me to get close enough to you to...seduce you..." Was Hailey's only response.

"Why, you little..."Nick said but he didn't appear angry at all, an amused smile on her face. "Come on, let's continue with my training. My mother doesn't pay you to sit on a bench."

Nick shook his head at her but he was still smiling. Together they resumed running, both behaving like nothing had changed. Nick continued to treat her like he always did and Hailey was perfectly fine with that.

12th August 2013 - Clothing Store, London

"Mom" Hailey said in a whisper "Since the first time I had an orgasm - you know with Nick, the day of my birthday - I'm always wet and aroused. Is it normal?" Hailey asked worried.

"Are you really uncomfortable?" Petunia asked her.

"Well, not really. It's just a little distracting but nothing I can't handle" Hailey replied with a shrug.

"Then don't worry about it honey. It can't be nothing but a good thing. When you'll have sex - real sex -, you'll be so sensible that you'll orgasm in no time at all. Men like women particularly responsive".

"Yes mom" Hailey said, a note of relief in her voice.

"Now, tell me what you think about this skirt" Petunia said, picking up a ultra micro mini black skirt that she wasn't sure would have covered her arse completely.

"Nice" Hailey said approvingly.

"There are a lot of these here: plated, denim, in leather. Choose as many as you want. You need a new wardrobe for the upcoming school year".

"Really?" Hailey asked excited.

"Of course honey. You will need tops too, ultra low-cut obviously. You need to show off those beautiful tits you have" Her mother said with a wink.

"What about underwear?" Hailey asked then.

"I don't see the point of wearing underwear honey. These clothes will cover you enough as it is".
