Sets her sights on Ron Weasley

"Hey Ginny!" Harry said as he nuzzled Ginny's neck at the dining table, right in front of everyone in the Great Hall! Ginny blushed but appreciated the attention, kissing him in return,

"Wow...you're very forward today Harry."

"Not as forward as you were the other day!" Harry grinned,

"What are you talking about?" she asked, genuinely puzzled, and now a little more red-faced. Her brother Ron was staring at both of them,

"You know..." Harry grinned, and whispered into Ginny's ear,

Tonks heard the next part from across the room, while she was sat eating at the Hufflepuff table,

"What?!" Ginny yelled, "what the hell do you think I am?"

"But Ginny I thought..." Harry protested,

"God, just leave me alone you creep!" With that, she stormed out, with Harry looking exasperated. Ron was shooting daggers at him.

Tonks smirked. Oh this was beautiful. She had wondered if she should obliviate Harry's memories so he wouldn't make a fool of himself with the real Ginny, but really where was the fun in that? Besides, she was sure that once Ginny did taste in the magic of the sex book, she'd come round and all would be forgiven. Or something. She'd get round to fixing things eventually.

Right now however, she had her sights set on her next prey: the currently very red-faced and annoyed Ron Weasley, who was as of this moment interrogating his best friend about what he'd been up to with this sister. Oh Ron, she giggled to herself, the things you will do to "Hermione Granger".

The next day, Ron was returning from Quidditch practise, without Harry, who he still wasn't talking to. It had made for a pretty awkward practise, but as goalkeeper he thankfully didn't have to talk to anyone too much. He had calmed down a little since the day before, but it was a matter of principle! No one, not even his best friend Harry Potter, treated his little sister like a slut!

Still in a huff, his expression softened a little upon seeing Hermione approaching down the hill. She was dressed in casual jeans and a mauve hoodie, though his monkey brain couldn't help noticing the hoodie was unzipped just enough to reveal her cleavage. As always, she had a book firmly clasped in her hands. He was happy to see her after all this drama,

"Hey Hermione!" he called. She grinned at him in return,

"Hey Ron!"

"You're a little late to see the Quidditch practice," he laughed affectionately,

"That doesn't matter, I'm here to see you!"

They embraced, and Ron noticed an almost intoxicating scent resonating from her, like lavender mixed with vanilla; floral and sweet. She smelled really good, and it made him embarrassed at how sweaty he must have been by comparison. She didn't seem to notice though, in fact, she reached up to his face and kissed him on the lips.

Ron wasn't going to say no to a make-out session, and enjoyed the attention,

"Wow," he exclaimed, "that was, well...you're..." he suddenly felt tongue-tied,

"Ron...Ronald..." she giggled, "I have this book and..."

"You want to study with me?" Ron asked. He'd been down this road before. One minute they'd be cuddling and kissing then the next they'd be sitting down to study for several hours. Classic Hermione,

"I think you'll like this book!" she declared. Well that was very unlikely, he thought. Still, he did like spending time with her, so if suffering a few hours going over potions was the price, he'd gladly pay it,

"So to the library then? I should probably get changed first..." he mumbled,

"No, no!" she smirked, "I was thinking somewhere really isolated, like the boathouse?"

Ron was taken aback,

"The boathouse? No one ever goes there!"

She winked at him,

"Exactly."

When they arrived at the boathouse, it was completely empty. The place was only used for first-years arriving across the lake as an old Hogwarts tradition. Other than that, it was almost never touched. Magic kept the place clean and tidy of course, but there wasn't much to the place besides the boats and decking. This was a pretty odd place to study, even for Hermione.

"What's going on, Hermione?"

She looked back at him, still smiling,

"I told you. I have a book I think you'll like."

With that, she held out the book she had been holding tightly the whole time, and placed it in his hands. It took Ron a second to process the title,

"Sexual Magic and Other Conjurations? You've gotta be kidding!"

"I'm not!" Hermione laughed as she unzipped her hoodie,

"But this is..." he hesitated and whispered nervously, "...sex stuff right? What if someone sees us?"

"Oh Ron, this is the boathouse! No one ever comes here!" The hoodie was on the floor now, revealing that she was wearing a grey tank top underneath, sans a bra.

"But this is so unlike you..." he felt himself squirm just seeing Hermione like this,

She looked at him encouragingly, and pointed at the book in his hands,

"Find a spell you like, and I'll do anything you want. I've already read it."

Ron tentatively opened the book and was immediately startled by its contents. Strange spells were accompanied by illustrations of extraordinary sex acts. He couldn't stop himself blushing from embarrassment. Seriously? Hermione wanted him to do this, or this, or THIS to her? At this point he had gotten so nervous he couldn't even turn the pages. Obviously he'd always wanted to get with Hermione, but between school always being busy and there never being any privacy at home with all his siblings and mum and...well...he'd just never given it much thought. To have Hermione approach him so brazenly about it now was well, it was exciting but also a little nerve-wracking. He kept wanting to turn his head for fear they'd get in trouble. Where'd she even get this book anyway?

Her hand appeared and turned one of the pages,

"Hey," she smiled lovingly at him, "it's okay, really. I'm up for anything."

He looked her up and down, noticing she'd even unbuttoned her jeans. He felt himself trembling,

"Well...okay...umm," he flicked through the pages some more, his eyes finally resting upon a particular illustration and accompanying spells. When Hermione saw it she giggled,

"Oh Ronald...you dark horse."

"You don't like it?" Ron stammered, "we can do something else if you'd prefe-" but Hermione touched her finger to his lips and said,

"Shhh, I like it. Please..." she stretched her arm out to him and softly caressed his face, "cast the spell on me."

Before he could respond, she had already begun to shrug her jeans off, revealing her slender white legs underneath and her small pair light-pink panties. Ron felt sweat dripping on his temples. This was...Hermione Granger...in nothing but a tank top and underwear. She saw his expression, and the bulge in his sweat-pants,

"Want to see more, big boy?" she teased as she pulled her top off, unveiling her flawless breasts to him. He could barely even speak, it was like his brain had completely vacated. All his thoughts were of her long slender body, he couldn't even look at the book. Again she turned to look at him and said,

"Need some help?"

Ron snapped back into focus. He still had the book in his hand,

"Sorry, yes, okay umm," he pulled out his wand and pointed it at the almost naked girl. Reading from the book, he said, "Incarcerous Equianus!"

Tonks felt a soft vibration against her body as objects began to materialise around her. Suddenly her arms were wrenched back behind her, forcing them together tightly into a long leather binder. A corset wrapped around her waist, pushing up her breasts with a harness pushing up through her cleavage towards her head. She felt a harness appear, tightening itself about her head before her mouth was **** open to allow in a bit. This was all fine but the next part was a little more uncomfortable.

Clamps instantly pinched her nipples to show off two golden tassels. A butt-plug punctured her panties to give her a matching tail, almost making her jump from the sudden penetration. She'd never had anything in there before! Long leather high-heeled boots covered her feet right up to her knees, causing her to shoot up several inches, nearly losing her balance. Straps connected the boots to her corset. Finally, a long fine lead rope reached from her head harness to Ron's hand. She was hers now.

"Wow," was all Ron could breathe. It was like a whole new world had opened up to him. Hermione Granger, his very own ponygirl? He just couldn't believe it.

Tonks wasn't sure what would happen next. Her mind was preoccupied with the instrument that had **** itself up her ass! It was a little uncomfortable, but as she tried to manoeuvre around bouts of pleasure tingled through her body. She looked down at her breasts, seeming even bigger pinched and pushed upwards by the corset. She gave them a little swish, making Ron laugh. She couldn't smile in return through her bit, but she was happy that she pleased him. She must look really good.

Ron had started investigating the book again, "I guess now we..." turning the page, he saw a new illustration. A small chariot, being dragged along by the ponygirl, with the man seated. They couldn't do that? Could they? The boathouse was too cramped, they'd need to go outside.

When he showed Tonks this, her eyes widened in alarm. She'd found them a secluded place for obvious reasons, but now he was wanting to take her outside?! It was broad daylight, anyone could be walking past! Ron Weasley really was a dark horse. She would have been more against this flagrant exhibition of herself, except for one thing. Giggling, she remembered that she was not exhibiting herself. She was exhibiting Hermione Granger.

Could she really do this to her friend? Well, she didn't have much of a choice now, Ron was already tugging her out the door. She was thankful that her legs hadn't been bound as well, although she was very wobbly in the heels. How the hell was she going to walk around on mud and grass in these? She'd need to figure it out quick, because Ron had already materialised the small chariot into existence! Climbing on board, she saw the immense pleasure masking his face. She'd really discovered something about Ron, hadn't she? Not only was he into kink, he was a dom with a penchant for humiliation. Despite herself, she rather liked this confident Ron Weasley.

Ron boarded the chariot, and instructed Tonks to stand before it,

"Now...mush?" Ron wasn't really sure what to say, "Onwards!"

Tonks didn't need any further incentive, although she was a bit unsure in these heels. Already they were sinking into the mud. She'd have to move fast to avoid getting stuck.

With the book and harness in one hand, and his wand in the other, Ron, noticed another spell that might help Hermione's movement,

"Whippiarmus!"

Tonks felt a painful crack against her ass, spurring her forward. Wow, Ron was really getting into this, she realised. Whatever reservations he'd had about this whole thing had clearly evaporated now his sexual fantasy was being realised.

Climbing up the hill was exhausting, but she didn't have any choice in the matter. Ron kept whipping her whenever she slowed down, so on she went, sweating and pulsating hard as she pulled the chariot up towards the school. He wasn't wanting her to go towards the school was he? The thought was humiliating, but also kind of a turn-on.

Now at the hill near the school, Tonks could already see students nearby,

"Hey, what's that?"

"Is that a naked girl pulling a chariot?"

"Isn't that Hermione? Hermione Granger?"

Oh boy, things were really starting to kick off. Hermione would never live this down, Tonks smirked. Thankfully Ron steered her back down the hill towards the boathouse, but not before the photographer student from the year below Colin Creevey had snapped a photo of the equine witch and her passenger.

Back in the safety of the boathouse, Ron released Tonks from her bonds, leaving her nude and very, very horny from her humiliating exhibition. He'd barely made it off the chariot before she immediately started tearing at his clothes,

"Fuck me, Ron! Fuck me right now!"

She'd just got his shirt off when he turned and said,

"Actually. I think...I want you to call me Master from now on."

Tonks stared at him, mouth agape. Really, Ron Weasley wanted Hermione Granger to call him, "Master"? This was unexpected. She really had stirred something in him. Without missing a beat she naturally played to his demand,

"Of course. Please fuck me, Master..." she purred,

"With pleasure."

Soon his pants and boxers were off, and she was on the floor with him on-top, sliding his cock and out of her like an automaton. She came first, letting out a scream as her body thrilled with released tension. This was even better a second time! When he came she saw the strain in his face as years of unrealised sexual energy blew inside her. He collapsed exhausted on top of her, groping her breasts as he did so. It had been amazing!

Unbeknownst to both of them, Colin Creevey had followed them back to the boathouse, and had taken as many covert snapshots as he could...
