Additional note: This story will begin at the same point as the fifth book, with all characters at Hogwarts being eighteen or older.

Harry laid in his bed, staring at the ceiling and thought about the very odd conversation he had with Dumbledore when he was on trial at the Ministry of Magic.

"Harry, if you could come here for a moment," the old wizard said, pulling Harry into an empty office. "There is something I need to talk to you about."

"Yes, sir?" Harry asked, wondering what this could be about. He had to assume it had to do with Voldemort coming back to power or something to do with the hearing that just ended.

"Harry, as you know, the world is a much more dangerous place now, with Voldemort once again having a physical form and gathering his supporters once more." Harry is more than aware of that, so he simply nods so that Dumbledore can continue. "We need to use every power at our disposal in order to fight him." Dumbledore looks down at Harry with a serious expression. "What I'm going to tell you about is ancient magic. Forbidden. Powerful. Taboo. You have to be prepared to do everything it takes in order to defeat Voldemort, otherwise, I will have to find someone else. Are you ready?"

Harry was a bit surprised at the notion that he wouldn't be anything other than totally comitted to defeating the man who killed his parents. "I am sir. 100%"

Dumbledore smiles down at him. "Good. Then I will entrust this to you," he hands Harry an ancient spellbook. "Take this. Read it when you can ensure that you're alone. The tome will reveal its secrets as you become more powerful. Beyond that, you will have to discover this magic for yourself." Before Harry gets a chance to ask any questions, Dumbledore is gone.

Now, finally alone for the first time since that meeting, in his bed, he pulls the book out from his bag. He studies the outside of it. It sure looks ancient, leatherbound and weathered, though he can almost feel a powerful magic emanating from it. He looks at the cover, which has the title in simple letters: The Magic Siphon by Mehmed Abdullah. Considering how powerful Dumbledore made it seem like this magic was, Harry had never heard of any famous wizards by that name. Perhaps Hermione will know. He will have to ask her tomorrow. Harry flips through the pages, finding all the pages after the first few blank. Is that what Dumbledore meant by having to discover the magic for himself? He flips back to the first page, more eager and excited than ever to see what kind of power this tome contains and begins to read.

I see you have discovered my book. Many lives have been lost trying to claim this power for their own, but only a chosen few can wield it. If you can read this words; you are one of them. For those you saw that many pages are blank, fret not! As you become more powerful, more will be revealed to you. I am sure you are eager to know the secret to how I became so powerful, so feared. As many scholars have deduced, I devised a powerful spell capable of siphoning off magical power, amplifying it, and transferring that power to myself. As with other examples of Dark Magic, this requires a sacrifice. The subject you are stealing power from must be subjugated. Totally. Where evil wizards might seek to do so by killing or torturing their victims, by solution is far more elegant and pleasurable, and so unique that no other wizard has ever been able to unearth the truth. In order to gain magic power, you must find women, whether willingly or unwillingly, seduced, tricked, or bought, and take them in their round behinds.

Harry has to drop the book and cover his mouth to stop himself from laughing. He was so immersed into the book, into the mystery, right up until that moment. This must be some prank that Dumbledore is pulling on him, though he seemed so serious. Of course, Dumbledore did always have that silly streak, though Harry would not have guessed that he would go in for that sort of humor. Grinning from ear to ear, Harry decided to keep reading.

When you do this, you will be able to take their magical power, and that from the environment and amplify it ten fold before adding it to your own. The book will track how much of it you have collected.

Looking further down, Harry noticed a dully glowing, golden zero at the bottom of the first page before returning to read.

There are rules to collecting magic power this way, of course, and you will find the most basic of these on the next page. As you gather more power, spells, potions, and more effects will reveal themselves to you. Use them wisely.

And with that, the first page ends with the glowing zero. Still chuckling a bit to himself, Harry puts the book away, and drifts to sleep. In his dreams, he is having sex with various female members of the school he has fantasized about: the beautiful Cho Chang, the curvy Professor Sinistra, and even his best friend Hermione, which is pretty normal for his dreams, only in this one, he is fucking them only in the ass. Every girl he fucks, he feels himself growing more powerful. Harry wakes up in a cold sweat, panting. The book suddenly doesn't seem that funny. He tries to shake off the feeling as he goes downstairs to eat breakfast with his two friends, Ron and Hermione.

Down in the Great Hall, the three friends were enjoying breakfast when Harry decided to broach the subject of the book, albeit in a roundabout way. "Hey Hermione, you know everything right?" He asked, making her roll her eyes and Ron snort into his porridge. "Have you ever heard of a wizard named Mehmed Abdullah?"

"Oh, him! Of course!" She says excitedly. "He was one of the most powerful wizards in the Ottoman Empire. They say he was more powerful than any other ten wizards of the age combined, though nobody knows how he amassed such incredible power." Harry tried to keep his shock from showing on his face. So not only was this person real, but apparently they were actually a powerful magician.

"What else do you know about him?" Harry continued, more than a little surprised that he was actually a real person, let alone a powerful wizard.

"Well, not much else is known. He kept to himself for the most part, though he did keep a massive harem," Hermione says matter-of-factly. So far everything is lining up perfectly.

"Anything else?" Harry pressed, hoping to learn more about the supposed author of the strange book that had been left to him.

Hermione blushed. "Well... there is one more thing..." she said slowly and quietly.

"Spit it out," said Ron, abnormally interested in wizarding history.

She turns even deeper red. "Well, they say he had a deep fascination with, um," Hermione looks around to make sure nobody else can hear and lowers her voice. "Women's bums." Hermione blushes even deeper before pulling back and falling silent.

"Don't we all," Ron said, laughing hysterically. Harry's face was set in stone. Ron's laughter dies as he seems how serious Harry.

"I have something I need to show you," Harry says. The three sneak way, led by Harry, to an unused classroom. He locks the door behind him.

"What's this all about?" Ron asks.

"I'll show you." Harry pulls out the book and explains the strange circumstances in which he received it. He hands the book to them, and as he talks, the two of them examine the tome. They open it up, look at the cover, flip it around, and generally examine the entire thing, cover to cover.

After Harry finished his story, Hermione looks at him with a frown. "Harry, this book has nothing but gibberish in it. I can't even read the title." Ron nods his head in agreement. He seems a little releived that he wasn't the only one able to read it.

"You can't. But I can." He sees the incredulous look on both of their faces. "Okay, fine, I'll prove it to you." He starts reading the first page of the book. The more he reads, the more Hermione's expression turns from doubt and concern to excitement and wonderment. By the time he finishes, Hermione is almost bouncing.

"If this is real, this answers a mystery that has stumped magical scholars for centuries!" She says excitedly. "Nobody has been able to figure out how Mehmed Abdullah was able to become so powerful! The method described in this book is..." Hermione crinkles her nose "crude and distasteful, but maybe that's the reason that no other historian has considered it before!"

Ron cuts through Hermione's excitement by busting out laughing, making her frown. "Oh come on, you can't be buying this. Are we really going to believe that some Middle Eastern wizard became super powerful by putting it in a bunch of different girls' bums?" Hearing it out loud does make it seem more ridiculous to the three friends.

"I agree it sounds crazy... but Dumbledore himself gave me this book, and I don't think it was just to make me laugh." The three students fall silent as they all regard the ancient book in front of them. What kind of untold power could be contained in such a small thing, or was it all just a hoax or an elaborate prank being played on them by their mischevious headmaster.

"I guess, scientifically, there is only one way to find out for sure, and that's by trying it out," Hermione says while slightly blushing. Both boys turn to look at her with wide eyes. Her slight blush darkens significantly. "Wait! Not with me! I mean some other girl!" she quickly clarifies.

"It's not like there are any other girls I can think of," Harry said. "It's not really a great opener either, 'Hey, let me put it in your bum to see if I unlocked the secret to a thousand year old wizards power.' I just don't see it going over very well.

"It's the only way to know for sure," Ron said, with a weird mixture of amusement, curiosity, and maybe even a hint of jealousy?

"No. Absolutely not. I haven't even..." Hermione coughs. "Either way, it's not happening, alright? You'll have to find another girl." The boys shrug and drop the subject. Over the course of the next few days, they don't broach the subject of the book again, however, all three of them think about it constantly. The only action any of them take is that Harry makes a potion described in the book that will allow him to, 'Enter the rear of any girl, no matter how small, without causing injury, regardless of if the tool is a dagger or a two-handed sword.' Mixing up a batch, Harry finds it to be slippery, consistent with its purpose as lube, with an odd, pale blue sort of glow to it.

After dinner on Friday, Hermione motions for the Harry to follow her. Curious, he sneaks out after her, making sure that Ron doesn't notice and that they aren't followed. Hermione leads him through the castle without a word until leading them in to a rarely used bathroom on one of Hogwart's many floors. Before Harry can ask what is going on Hermione opens her mouth.

"Given that this could be the greatest magical discovery of the century AND could prove to be an invaluable weapon against He-who-must-not-be-named, I have decided to volunteer myself as a test subject, given that I don't want to have to wait months, if not years, on your lack of romantic ability." Hermione speaks with her usual confident, if slightly condescending tone, framing the offer as if she is offering to go on a dangerous mission. However, it isn't anything like that.

"You're going to let me put it up your butt?" Harry asks bluntly, both confused that his friend would offer to do this as well as aroused. Blood begins rushing to his cock just at the possibility.

"No! Well, I mean yes, but could you not phrase it that way," she says sheepishly. "Considering what is at stake, I don't see there being any way I could refuse," she says, not mentioning the fact that is was actually her who brought him to this bathroom.

"I'm not going to say no that!" Harry says excitedly. He desperately wants to know is this book is the real deal, not to mention the fact that Hermione, despite being one of his closest friends in whom he has zero romantic interest, has been the subject of many sexual fantasies.

Hermione conjures up a cushion to put on a bench in the bathroom and takes off her robe. She bends over onto the cushion on her stomach, turning over to Harry with a slightly scared expression on her face. "Just be gentle, okay?"

Harry nods. "I will. I promise." Hermione, seeing no other reason to delay, takes a deep breath and lifts up her skirt and pulls down her white, cotton panties. Her ass is smaller than he had imagined in his fantasies, though he isn't surprised given how slim she is. Still, it's a nice, shapely rear end, and most importantly, it's in front of him and naked. Harry pulls down his pants and approaches, his cock throbbing, ready for action. However, even after generously lathering his cock with pale blue glowing lubricant, he isn't so sure that Hermione's tight little ass is ready for his cock just yet. Coating his pointer finger in the lube as well, he gently teases around her virgin asshole. She gasps when he makes contact, and Harry can tell that she is steadying herself for the eventual penetration. Ever so slowly and gently, he slips his finger into Hermione's asshole.

"OW OW OW!" she exclaims. "It's so big!" she whines, her head falling down between her arms as she grits her teeth.

"That's just my finger," Harry replies, feeling a bit chagrined at what he is putting his friend through. His massive excitement and arousal allow him to push through it. Hermine whimpers when he speaks, though she doesn't reply to his words. Pushing forward, Harry gently eases his finger in deeper, feeling the uncomfortable girl clench her asshole tight as he tries to loosen her up in preparation for his cock. "Try to relax. It'll help us both," he tells her, though he doubts whether or not she will actually take the advice. Surprisingly, he is able to get a bit more in after speaking, working his finger slowly in and out of her, trying his best not to cause her any further pain.

Meanwhile, his other hand went to his dick, stroking it slowly in tandem with the finger sliding in and out of his friend. Harry is entranced watching Hermione's tight ass accept his finger as he slides it deeper and faster as body molds itself to accept her new role as Harry's anal fuck toy. "Are you ready for me to put it in?" Harry asks.

"You're not in yet?" Hermione whimpers, which Harry takes to mean yes. He slowly pulls out his finger and lines his cock up with her asshole, seeing her entire body clench up as the tip of his cock touches her backside.

"You're going to have to relax," Harry says, hos cock seeming huge against Hermione's small and tight ass. He pressed forward, but her tight hole resisted him, not allowing him the entrance he so desired.

"It's not that easy," Hermione grunted, shifting her body around as if there was a more comfortable position.

"You're going to have to help then. Spread your cheeks," Harry orders her. He can hear her muttering under her breath in displeasure as she complies, her hands spreading her ass cheeks in order to give Harry the access he needs. This time, when Harry presses forward, it works, and the head of his cock disappears into her behind. Waves of pleasure overtake Harry as he finally enters Hermione.

"Bloody hell!" She yells, clearly feeling something, and not the kind of pleasure that Harry is. This was one of the first times he had ever even heard her curse. "It's huge!" she manages to gasp out.

"Sorry," Harry apologizes, grinning at her unintended compliment. True to the description, despite how tight she is, Harry can tell that Hermione's ass is able to take his lubed cock as it is, so he pushes in deeper, barely hearing her whimper as more and more of his cock disappears into her. In all of his fantasies, the girls Harry fucks all had nice, big asses, however there has to be somethig said for the view of a small, tight ass being stretched by a bigger cock. With the magical, glowing lube, Harry is just able to move in and out of her, her ass gripping his cock tightly as he fucks her for the first time.

"Is this going to take much longer? It really hurts," Hermione says, punctuating her statement with a slight whimper.

"I don't think so," Harry answered truthfully, knowing that the pleasure he was getting from fucking his friend's tight little ass was going to put him over the edge far quicker than he wanted to.

With a grunt, Harry grabs Hermione tightly by the waist and unloads into her recently deflowered ass. It was his first time as well, and despite finishing quickly, he finished hard, pumping her small, tight ass full of the largest load he had ever blown in his entire life. His cock pulsed and her ass twitched as his cum poured into her. Hermione's head drooped as she let out a quiet groan, the pressure of the cock inside her recently virgin ass still there, though greatly diminished since Harry was no longer actively fucking her. Between him stopping, and the feeling of something liquid filling her up, Hermione must have figured out that her first little anal adventure was coming to a close.

"Did you, uh, finish?" Hermione asked awkwardly.

"Mmmm, yeah I did," says Harry, holding his cock inside her as it slowly deflates in her tight, cum filled ass.

He could have just sit there and watched in silence, but Hermione interrupted him. "Did it work?" she asks.

Harry opened his mouth to ask if what worked, so absorbed in the pleasure of taking his friend's anal virginity that he completely forgot the true purpose of this little excercise. Luckily, he managed to catch himself in time, going to grab the book that he had completely forgotten about until just now. Opening it, he quickly turned to the page with the glowing zero. Only now, it wasn't a zero. It was a glimmering one hundred and fifty, glowing much brighter than before. Harry's jaw dropped in shock. It worked. Even besides the number in the book, now that he was noticing anything besides the pleasure of his sexual excursion, he could feel power welling up inside of him. A kind of power that belonged to him, and yet one he could tell wasn't his own.

"It worked," Harry said lowly, handing the book to Hermione. She couldn't read the words, but her eyes widened as she saw the change in the number in both size and luster.

"It really worked..." she said under her breath, her eyes narrowed in concentration as she tried, in vain, to translate the symbols on the page into words she could comprehend. Over her shoulder, Harry looked as well, rereading the words in a new light now that the author was telling the truth. In the quiet bathroom, both of them were so enthralled in the book that they both nearly jumped when a sound interrupted the silence. The sound of a quick, but loud, fart. Harry looked at Hermione in shock, who turned beet red as a hand rushed to cover her deflowered and leaking ass.

"Don't look!" She yelled as she struggled to get off the bench with one hand covering herself. "Go wait for me out in the hallway!" As she spoke, another small fart erupted from her rear end, and cum began leaking out from around her fingers as she waddled as fast as she could for the toilet.

Before he even has a chance to go anywhere, a loud, long fart erupts from the bathroom stall, followed by a splash as cum is ejeceted from Hermione's tight ass. That is followed by a quiet whimper as Hermione's poor, abused asshole suffers even more punishment. Almost against his will, Harry found his ear pressed against the stall. He is soon rewarded with another release of gas, this one shorter but louder, and he was able to hear Hermione exclaim, "Owwww!" even before cum splashed into the water below. Hermione began breathing heavily, and he could tell that she was ready to expel the rest with one last push. She took a deep breath and he could hear her straining and gritting her teeth before unleashing the loudest, longest one yet, filling the toilet bowl with his cum.

Harry had to quickly move himself away from the stall door when he heard the toilet flush, dressing himself as rapidly as he could. Luckily, he was able to get dressed in time, surprising Hermione when she exited the stall.

"Have you been there this whole time?" she asked, turning beet red.

"No, of course not, I just walked over here," he said, which was techincally true, but of course concealed what had really happened while she was sitting on the toilet. Nodding, she awkwardly shuffled to her clothes, trying to shield her body from his view, as if he hadn't just demolished her ass with his cock. Women could be silly sometimes. Once dressed, she seemed a little more at ease, though she walked with a noticeable limp.

"Come on, let's get back to the common room before anyone notices that we are missing," Hermione says, leading the way back to the Gryffindor common room. Walking behind her, Harry couldn't help but stare at her from behind, knowing what she had under that skirt, and already reminiscing about what he did with it. The walk was over far too quickly for his liking, and soon they found themselves back in the common room.

"Should we see if anything has changed with the book?" Harry said eagerly, and to his shock, Hermione shook her head. He had never seen her turn down the opportunity to read a book before.

"Maybe tomorrow... I think I'm just going to head to bed," she said, unsteadily making her way towards the girl's beds. "Night."

"Good night," Harry said, perplexed at her unusual behavior. Still, that didn't mean he couldn't learn anything more, and with a quick glance around to make sure nobody else was looking at what he was doing, he opened the book once more.

Sure enough, after flipping through a few pages full of text he had already read before, Harry ran across a new page full of writing. Excitedly, he read it all. The first section was devoted to a spell. It was unlike any other spell Harry had ever heard of. For one thing, the spell needed neither wand nor incantation. Instead, he simply needed to focus his thoughts and the spell would be cast. The spell itself was different as well. Upon casting, soldiers would form out sand and arise to do his bidding. The book mentioned that, at first, he would only be able to summon one and it could only follow simple commands, but with enough power and practice, he would be able to summon armies capable of following complex orders. Given that Voldemort was currently gathering followers to form his own army, Harry felt a surge of hope as he now knew he would be able to form one of his own without endangering the lives of those closest to him.

The second section spoke about some of the effects that the power and the book would have on the user. That did worry Harry quite a bit at first. After all, the wizard who wrote the book was known as a dark wizard, and dark magic was well known to have a negative affect on those who practiced it. Harry worriedly touched his nose, relieved to find that it was still in one piece. If he had kept reading, he never would have been worried in the first place. The first effect was that the user would slowly grow to have more stamina, both sexually and physically. The user would also grow in terms of his manhood, and the amount that he could ejaculate, which was, of course, a very exciting prospect for a horny teenage boy. Finally, there was a mental change as well. Given how power was generated with this method, access to more women was something that was borderline required, and so, the book offered help in that realm as well. As he spoke to women who he sought to fuck, the book would read as much about the female target as possible and offer subtle hints to the user as to what kind of tactics or words could be used to get them to bend over and take off their pants.

Harry almost couldn't believe his luck as he reas the newest additions over and over. Perhaps it was for the best that Hermione left when she did so that Harry would be able to use this new information without her knowing about it. Speaking of Hermione, the last sentence he could read hinted at an effect that he would have on his repeat female partners. However, that next section was infuriatingly blank. Still, Harry went to bed with a massive smile, holding his book like it was a dear friend as he fell into a deep, restful sleep.
