A/N: So this is where the story earns its M rating. If the description of teenagers having, talking about, or thinking about sex bothers you, turn back now. Honestly, if people believe that teenagers don't think about these things, they're sorely mistaken.

Hermione was dreaming.

Her rapid heartbeat, shallow breathing, and the light sheen of sweat covering her skin might signal an unpleasant vision, but this was no nightmare.

Quite the opposite, in fact.

Hermione was in the middle of a very erotic sexual fantasy. She just didn't know who with.

The shadowy figure currently attached to her lips by means of his own, seemed familiar in some way, but she couldn't quite place it. No, not his taste, or his touch, though those were both very nice and her bits were quite appreciative, thank you very much. His scent seemed moderately familiar, almost like a combination of leather and... well, that other was quite obviously her own. His touch seemed to be bringing about some nice reactions that she certainly wasn't unhappy with.

She continued searching for the thread of familiarity as a hand crept up her skirt (since when does she wear skirts outside of Hogwarts, especially this short?) and, with a sharp slap to her bottom, derailed her train of thought. She started with a little squeak as the stranger once again spanked her butt. Intending to be incensed about this turn of events, she was instead concerned about the state of her knickers.

Or lack thereof.

Laying in her bed sleeping, Hermione blushed ferociously.

She liked the feeling of her bare butt exposed to the air, especially since the shadowy stranger had continued to spank it. The thought of anyone seeing her like this, with her skirt up over he hips and her business out for everyone to see sent a shiver of pleasure through her core. Yes, this was definitely the way to go.

A disturbingly naughty idea crept into her head.

She was such a dirty little witch.

Hermione quietly browsed through the offerings, carefully inspecting the books before putting them back in their proper places on the shelf. She didn't know why, but she just couldn't decide on something to read. That was never a problem before as she could usually just pick up any book and enjoy it. She needed to clear her mind. Maybe a quick release session back home. But first...

She "accidentally" dropped a couple of the books she had managed to select before she started getting too hot to think straight. Bending over to pick up her dropped items, she blushed at her predicament. Not wearing any knickers to the library, where anyone could see. She should be embarrassed. People knew her here. She should be ashamed.

She was so turned on.

After giving the room the required three second show, Hermione stood back up, the dropped books in her arms and hurriedly turned to leave before a soft, deep voice in her ear stopped her.

Dirty little witch.

A sharp crack like an apparition sounded and Hermione jumped in surprise, a small squeak jolted from her at the contact.

He had spanked her bottom.

Hard.

She turned around but, of course, the aisle was empty.

Hermione drained the last of the potion that Madam Pomfrey had sent home with her from school, and grimaced as she corked the glass phial and replaced it in her potions kit. Finally, after weeks of these foul-tasting concoctions, she had finished the regimen of healing potions the woman had prescribed to assist her in her recovery from the curse she had taken in the Department of Mysteries. She was slightly bothered, however.

She frowned as she remembered her dreams from the past few nights. They had been gradually becoming more and more erotic. She was waking in the morning, covered in sweat and smelling of sex. That part didn't really bother her all that much. In fact, her sleep these last few days of the potion regimen was the best she had gotten in months. The part that concerned her were the day trips. She didn't go far, usually just to the library by rail, but her activities while there were well past indecent and now pushing into illegal. The day after "The Spanking Incident" (as she referred to it), she had returned, only this time without her bra as well. She knew people could see through the white shirt she had worn. But when she "happened" to fall out of it while reaching for a book up high?

She was so randy.

Her nipples ached thinking of that day and the pinching they had gotten while there. Her mysterious stranger from the day before had shown up again, whispering in her ear, and squeezing her hard little buds.

Dirty little witch.

The thought of the voice in her ear made her shiver.

Today, after another erotic night of dreams, she hopped on the rail, again planning on going to the library. At least nothing new had been added to her ensemble, she thought with relief. She was still missing her panties and bra, though this concerned her less than it did the day before. Upon arrival, something told her that she wouldn't find what she was looking for today and she needed to get right back on and go home. She had grabbed a seat in a nearly empty car, and made herself comfortable in the back. Just as the train left the station, she started to feel it. Not much, just a little heat in her belly, but Hermione knew what was happening.

She was getting horny.

She had tried to ignore it as long as she could, she really did, but there she was, not five minutes into the ride and she was discretely rubbing herself off in her seat. Well, as discretely as one could rub oneself off in a public rail car. After gritting her teeth through a mind blowing orgasm and fixing herself back up so she didn't look like a freshly shagged strumpet, Hermione looked around the car. Nobody was grinning at her or throwing her lecherous looks and she thought she had gotten away with it.

Dirty little witch.

He had kissed her neck and, while she was sighing in ecstasy, disappeared.

Tonight was the last night of the potions that she figured for the cause of the odd behavior, however and, while she would miss the restful sleep she was getting, she was tired of her voyage into exhibitionism. Hopefully tonight would be the last night for these dreams and she could stop acting like a hussy. So slutty.

Shameful.

Dirty.

Hermione nervously shuffled from foot to foot as she stood outside the entrance to the library, once her favorite haven, but now rapidly becoming a source of stress for her. This was getting ridiculous. Last night's dream took it too far. She knew because she woke, sore as all bloody hell, with her fingers crammed between her legs and her face mashed in her pillow.

Who sleeps like that?

She wanted to leave, she really did. Whatever her subconscious wanted from her this time was too much. She willed her feet to move but they stayed stuck right where they were on the sidewalk. She whimpered lightly, looking for something, anything, that would get her out of this mess. "Hey! Hermione," a voice yelled.

Of course, it was him.

She nearly cried in relief as she recognized Harry Potter running through the crowd. He grabbed her in a hug and she trembled in pleasure at the contact. If anyone could fix what was going on with her, it was Harry. Her Harry.

"What are you doing out here," he asked, amusement in his voice. "There're no books outside." He grinned at her but dropped the smile as he caught sight of her worried look. "Hey now, what's wrong?"

Hermione just shook her head. "Don't ask me why but... can you just take me with you, wherever you're going?" She didn't care where it was, as long as Harry was there, she would be okay. "I just really need to get out of here. Right now."

Harry's eyes darkened quickly. "Is everything okay?"

"I'm fine," she said, giving him a small smile and a nod. "I just want to get out of here."

"Well, why don't I take you home? Privet Drive is kinda far from here," he added lightly.

She quickly agreed, as her parents were out of town at a dental conference for the weekend and would not ask questions about the boy bringing her home. The reason for Harry being so far from his aunt and uncle's house in Little Whinging unsupervised never crossed her mind. She took his hand and finally got her feet moving in the direction of the rail platform. The ride passed uneventfully, as Hermione, thankfully, had no inclination to expose herself to anyone on the line today. As they got back to her unoccupied house, she began to feel a bit ridiculous. Maybe she had been wrong, or maybe the potion had worn off? Anyway, the business at the library didn't seem to be bothering her anymore.

That was, until she sat down on the couch next to Harry. Then, the fluttering in her belly, the flushing of her face, and the heating of her skin all returned full force. She lowered her gaze to her lap, trying to hide her surely burning cheeks.

"Hey now," he said, reaching under her chin and lifting her face up to meet his eyes. His deep, green eyes. "What happened? You can tell me anything." She really could. Harry would never judge her.

And so she told him of the last four nights' worth of erotic dreams and their following days, leaving nothing out. By the time she reached the latest dream, she was almost quivering on the couch. It was amazing that Harry hadn't noticed and commented yet. "Last night was the craziest," she said, reaching the reason for meeting him today. She tried her hardest to get the details. This one had remained a bit fuzzy when she woke up but it was clearing up as she sat here with Harry and talked about it. "I remember I was in Hogwarts, in the Great Hall. Everyone was there, but the perspective was wrong. I was higher up and all the way in front. At the Head Table." Her belly fluttered again and she had the distinct urge to touch herself. She fought it down and soldiered on. "Something was wrong though," she started again, frowning. After a moment, more came to her. "Everyone was staring at me." A pulse of excitement ran through her, tingling her every nerve ending.

"Did you feel embarrassed," Harry calmly asked her.

Her nipples twisted up into hard little points. "No," she almost moaned, "I liked it. I felt proud. I think... I think I was naked." This time she did moan and she couldn't stop her hands from running up and down her bare legs.

Harry paid this no attention. "What else? Think Mione."

"I can remember feeling so randy. Like I wanted to do nothing else but shag. Hussy," she said throatily, her tongue darting out to moisten her lips. "And I was." She was having a hard time fighting the urge to cram her hand between her legs. "Next thing I realize, I'm getting what I wanted, and hard. Right there on the Head Table, Harry." She looked up, into his eyes.

Those beautiful green eyes.

Her hands had traveled so close by now that her skirt was bunched around her thighs. Surely Harry could see that she was exposing herself! What must he think of her? Not wearing any panties. So shameful.

"Everybody is watching. Ron, Neville, Luna, all our friends, our teachers, everyone I've ever known is there watching me get shagged by someone I don't even know." Hermione was starting to sweat as the pressure was getting to her and her arousal had to be obvious to Harry by now. The proof was in her nostrils.

"Is that all," Harry asked again, the calm tone breaking slightly.

"No," Hermione admitted, shaking her head. "There was one more thing. He..." She hung her head, not meeting his eyes.

"You can tell me, Mione. Look at me," he told her. She met his gaze. Those eyes. "Tell me."

By now, Hermione's sexual engine was on overdrive and she couldn't handle much more of this. The vivid picture came back to her, filling in details she hadn't even known up until now. "He buggered me, Harry. Right there on the Head Table in front of everyone and... and I loved it! I moaned and I screamed for more and I loved every second of it. I'm such a-"

Dirty little witch, he finished softly in her ear, setting her off on her most powerful orgasm to date. As she came quivering down from her sexual plateau, he leaned her down to lay in his lap. "I should be honest with you now, Hermione. I've been dreaming these past four nights as well. Up until I sat down on your couch, I had no recollection of anything I dreamed. As you started telling me about your erotic dreams, my memories came back to me. Dreams of a little tease, showing off her bits in the stacks at the library." She moaned as his hand came in contact with her bare butt then ghosted up her front and cupped her breasts. "Dreams of a slutty little hussy who plays with herself in front of everyone on the rail." He gave her a light slap on the rump, causing her to sigh in contentment. "Dreams of my hot, sexy friend, Hermione Granger getting shagged senseless in the Great Hall at Hogwarts."

She sat up facing him, perching on his lap. "I'm such a little hussy," she breathed and he sucked her lip into his mouth, claiming her mouth with his tongue.

"You are," he said, releasing her, "but you're my hussy." She whimpered in response. "Say it," he ordered.

Hermione studied his gaze intently. Accepting what she found there, she asked him one thing. "Promise you'll never leave?"

"I'll be with you, forever," Harry said calmly, staring into her hazel eyes with his deep green ones. "Now, Mione. Say it."

Dirty little witch.

A/N: So there's that. There will probably be only one more chapter after this one. I won't spoil it for you so don't ask :) Thank you in advance for leaving me a review!
