Author's note: Wow, okay, well, that was some heated reaction to last chapter and the inclusion of Ron. I would like to point out that this story, being commissioned, means that I am writing by the directive of someone paying real, actual money dollars for the story, and keeping them happy is my chief concern. But, on top of that, sorry if sometimes polyamory means the girls get to have sex with people too; it's not going to be a focus in the story, but it might happen on occasion.

A few days of settling into routine had drone Harry some good, as he got used to his classes once more, dealt with the Slytherins being extra snooty in the wake of their dark lord's resurrection, many of their families tied to the Death Eaters and carrying chips on their shoulder as they sneered at the boy whose very life blood was rumoured to have given Voldemort new life. Not that the rumours of Voldemort's resurrection were true, of course, and there was no way that the Slytherins would have known if there was; their intimidation tactics were efficient, and in general people were not too willing to believe it. Not when the Ministry was saying it was nothing and plenty of people whose families had inside ties were swearing that Harry and Dumbledore had lost their minds.

Instead of letting it bother him, Harry got busy with his school work, now managing four girlfriends all at once. Quickies here and there kept his insatiable appetites at bay and ensured all fours girls were satisfied, even if it took plenty of schedule coordination to do so. It was well worth the price to get things rolling, as he already slipped into the sort of things that were sure to keep everybody very, very happy with the new way of doing things. But most curious to him was Hermione, who for his best girl seemed to be drifting off plenty, vanishing for long stretches of time even when she wasn't dealing with Prefect duties, and finally he understood why when she slammed a book down in front of him.

"You've vanished off to do research again," he sighed, shaking his head as Hermione quickly sat into the seat opposite him, her request for him to visit her at the library fairly obvious enough in intent. "You know I worry less when you tell us you're going to do it instead of just disappearing to, right?"

"Shush, that's not important," Hermione said, waving it off as she brushed some of her messy hair back. She opened the book quickly, thumbing through the pages. "Being a prefect lets me into the restricted section, and I've been through it lately in search of something. Do you remember that history of magic lesson about Amar Caru?"

"Hermione, I don't remember the history of magic lesson we had this morning." The painfully boring class did very little but put him to sleep, and it was only through her intense coordinated study sessions that he ever passed the class, taught by a painfully boring and monotone ghost who Ron jokingly suggested was so dull he didn't even know he was dead. "You're going to need to be a lot more specific."

Clicking her tongue, the bookish girl shook her head. "Second year history of magic, third section? No?" She looked at him with wide eyes, acting like he should know it, before shaking her head and brushing it off. "You'd still be in third year without me, forget it. What matters is, Caru was a Welsh wizard from the sixteenth century who took multiple wives, and he was able to draw power from their love. It's said that he used that love to defeat a fearsome warlock at some point, one who was terrifying much of Eastern Europe, and who could not be stopped by anyone else. But here's where it gets strange." She turned the book around and shoved it in front of Harry.

Looking down, Harry tried his best to read the page quickly, not able to ever do half as well at speed-reading as Hermione, but quick enough to catch it all while Hermione's high expectations had her only slightly frustrated with how long he was taking before he looked up in shock. "This says that it's been rumoured his mother died protecting him, and that-"

"That he survived the killing curse. But it's only a rumour, and they've never been able to verify it's what happened, because nobody ever found his parents; the assumption is that they ran away and left him with relatives. Which is why it was out of the books we had, and why you're still considered the only one, but keep reading, please." Hermione was excited by what she had found, and the prospect of what could come of it left her giddy as could be. "Go on, it gets a lot more interesting." She looked down at him, smiling and chewing on her bottom lip as she watched his expression. This was some revolutionary stuff, and she didn't want him to stop until he got to the good parts.

"'Raised by his grandparents, the unverifiable claim was what he alleged gave him the power he was famous for wielding. Allegedly, the sacrifice of his parents' love allowed him to draw power from his lovers and use their own magic to fuel his. Although it remains a mystery exactly how he was able to empower himself with the more lovers he took, his harem was reportedly in the dozens, and each woman added into his marriage was another witch's power added to his own.' Does this mean what I think it means, Hermione?"

"I think it does," the brunette said, nodding steadily. "If this is true, then you might actually be onto something with this idea of seeing how many girls you can have sex with. In fact, you might want to push it even further than that; this might be the key to fighting Voldemort. Sirius might have inadvertently given us the key to ending the war." She closed the book quickly and pulled it back toward her, smiling wide. "It will take a lot more searching to find out what sorts of things 'drawing power' even entails, but I think we might be on to something here." She slipped the book into her bag and looked around, chewing her lip even more intensely now. "I'm going to do my best to keep looking when I have some free time, but if you're not too busy now, maybe we could go find somewhere to..."

Harry smirked, placing his hand onto Hermione's and guiding her off to a secluded corner where he could deal with her issues. "You've spent too long in the library."

"I have a little bit of time before Arithmancy so we can't go for long, but we can fuck again after Potions."

(Scene break, thanks for removing my usual rows of asterisks)

There was one downside to being back at Hogwarts, one loathsome element that no amount of pre-class quickies could possibly soften the blow of. Double Potions class with the Slytherins. The most unappealing sentence Harry could imagine as he walked to class flanked by Lavender and Parvati, fresh off of a double blowjob from both of them, and he drew a few curious stares as they walked into the room together. Everyone knew that he was with Hermione, but all eyes were on him as he had his arms around the waists of the two lovely girls in his year, which immediately set the Slytherins abuzz with rumours that the Gryffindors had already been well aware of, given that it was only the fifth years in the room; Harry was shagging the girls, and the other boys in his house and year had come to live by the sock on the door warning Hermione had suggested, apparently a trick in muggle schools that worked out quite well.

All eyes were on Harry, scandalized gasps ringing out as Harry gave a quick swat on the behind to both of the girls he'd walked in with, before sitting down beside Hermione, Lavender and Parvati to his right, and not minding his arrival in the least, Hermione leaned in to give a quick peck on the lips to Harry, before turning her head further back, looking over her shoulder with a smile. Sitting two rows up, a gaggle of Slytherin girls seemed appalled by what they were seeing, except for one. Pansy Parkinson seemed more confused than outraged, with a glimmer of curiosity in her eye that Hermione caught. The Slytherin girl gasped as she realized Hermione was looking at her and that she had caught a peek at her reaction, immediately scowling and doing her best to play it off with a look of disdain. The sort typical to give a lowly muggleborn, as a proud Slytherin girl.

Quick on the take, Hermione's thoughts ran rapidly, wondering about a great many things as she turned back toward the front. Pansy's curiosity was intriguing to her, as she held close beside Harry, thoughts bubbling up quickly with curiosity and excitement. There had to be some way to take advantage of that reaction, embarrassed and stubborn as she was about hiding it behind a sneer. The thoughts stuck with her throughout the entirety of class, keeping her distracted as she sat there in thought, barely following Snape and his steadily droning lesson. For once in her life, Hermione Granger could not focus during class, but the more she thought on it, the easier it was to convince herself it was for a noble cause, because she felt that she was on to something absolutely brilliant in its execution.

As they began to work on their potions for the second half of class, Hermione leaned in close, voice low as she spoke only so Harry could hear her. "How serious are you about what we talked about earlier?" she asked.

"You mean how I really should get a quadruple blowjob some time?" Harry joked, smirking as he nudged Hermione in the shoulder, before his face went steady, able to tell that she wasn't too amused with his remark. "You mean the stuff about the Welsh polygamist."

"Yes." Hermione shook her head, measuring out some lizard scales and doing her best not to let conversation interfere with her work, both for the sake of getting the potion done and to ensure that Snape didn't come over and ask why she found talking more important than the assignment. "I need to know if you really want to look into turning your desire to just sleep with as many girls as you can into something that could actually stand a shot at defeating Voldemort."

"I would do anything to stop him," Harry said, his voice steady enough to let her know that he meant business. "And if you really think that there is something to this Caru guy then I'd say we need to start looking into it immediately and find out what we can do. But is this really the time?"

Hermione didn't worry about the idea she might be overstepping bounds as she pressed firmly onward. Something inside of her was emboldened and fierce, driven by the intense desire to see justice done and to bring an end to the conflict before it had even truly begun. "We're at war, Harry, there isn't ever a 'good' time, but actually, there's a reason. If you really want to do this, then we need to know what's going on with the other side, since we can't do any reconnaissance here at Hogwarts."

It wasn't hard to follow after Hermione's logic, nodding slowly and steadily along as he realized exactly what she was getting at. "We need a spy," he said, keeping his voice low. Lavender and Parvati were both steadily at work on the potion beside him, and he felt like there was a time and a place to talk about what he had in mind, but it wasn't now. "But who? None of the Slytherins are going to give us the time of day or sell out their families."

"Not exactly." Her eyes drifted off to the side. "Grab Lavender's mirror next to you and use it to look over your shoulder, two rows back."

Hearing Hermione get so intense and worked up had Harry curious as to where this was all going as she started to slip a little more subtlety into the matter than usual. Generally, these sorts of impulses and intensity only came from something actually transpiring, but Harry found himself all too interested to see what was going on, and he slipped the mirror from beside him and lifted his upper lip, pretending to check if there was anything in his teeth as he tried to angle it such that he could peek further back. Two rows behind him was Pansy Parkinson, flanked by Daphne Greengrass and Tracey Davis, and she was oddly unfocused, mostly because she was looking right down toward the back of Harry's head, chewing on her bottom lip and clearly deep into thought.

"You can't be serious," Harry groaned, slipping the mirror back down onto the table.

"I am," Hermione said, smile broad and wicked. "I think the key to having someone on the inside is for you to seduce Pansy Parkinson."

(Scene break)

It wasn't easy for Harry and Hermione to isolate Pansy. She rarely moved without the other Slytherin girls in her year. The conversation with Luna, Parvati, and Lavender about what they had found was going to have to wait a little while, although Ron heard a basic rundown of it, as they needed his help to get the table set. Unable to rely on Harry's other girls to help get Pansy alone, it fell on Ron and his twin brothers to run a distraction; Pansy was a prefect, and surely if there were to be an 'accident' involving an unfortunate Fred and George experiment that left Pansy's clothes and her face covered in thick green slime, she would run off to the exclusive Prefect bathroom, where Harry and Hermione lay in wait for her. Patient, steady, and Harry totally not rubbing his bulge against her ass while he lifted up her skirt and rubbed the front of her panties.

"Go ahead without me!" Pansy shouted from the doorway to Daphne and Tracey. "I don't know how long it will take to wash this shit off of me, but I'll catch up with you. Fucking Weasleys, breeding like rats and ruining my clothes." She grumbled and swore her way over to the sink and began to draw water, hoping to wash her face off and get some of the goop off of her clothes before heading down to her dorm room to change. Once she'd gotten the green off of her face, she finished off her muttered rant with a crystal clear, "I bet Potter put them up to it."

"Actually, it was all Hermione's idea," Harry said, smirking as he caught her by total surprise. The Slytherin girl nearly jumped out of her skin, and turned furiously on her heel, catching Hermione positioning herself between Pansy and the door.

"You're not supposed to be in here," she sneered. "And Granger, you didn't even last a week as prefect before you broke a rule, and I'm going to report you for this. He's not supposed to be in here, and-"

"Cut the bullshit, Parkinson," Hermione said, voice sharp and steady as she stepped toward the Slytherin girl. Her body was lean, not as waify and wiry as Luna, but she didn't have very many curves to work with. "I saw the way you kept looking at Harry and I during class. You can't stop thinking about it, whatever it is, can you?" She took a step forward, smiling as she approached Pansy, making sure to keep not only some distance from her, but her body positioned such that Pansy would have to go through her to get out. "You want answers, but I think you want even more than that."

"Fuck off, Granger," Pansy sneered, as Harry loosened his robes a little bit, her eyes pulling sharply away from him as he slid them off of his shoulders. "This is a terrible mind game, and if you don't move right now, you're going to be in a lot more shit for cornering me like this."

But Hermione was undaunted. "You don't just want to know how all three Gryffindor fifth year girls can date Harry Potter at once, do you? Come on Pansy, answer the question. What can't you get off your mind?"

Pansy's hands pushed back and gripped the sink tightly, her jaw quivering nervously a little bit. It felt so wrong to admit the words, but even now as Harry drew closer, her eyes were struggling not to look further down. Harry was no longer the stringy nothing of a boy who had shown up at Hogwarts, now well fed and in incredible shape, burly and grown up and more handsome than she was even remotely comfortable admitting he was. "I...I want to what's so incredible that you have three girls willing to share you."

"Four," Harry corrected, but instead of telling her that Luna was a year below them and in Ravenclaw, he just kept moving forward. "And I can show you, but are you sure you want to know?"

"Are you sure you want to live with knowing that you're attracted to Harry Potter?" Hermione asked, drawing even closer, now right up in Pansy's face, seeing the way the black-haired Slytherin fidgeted about; she wasn't going anywhere. "Because I wouldn't mind letting you join in, but I have to know that you're not going to run out halfway through having fun because you're worried about your reputation." Although, even as she acted like Pansy couldn't be trusted, she was easing the Slytherin down onto her knees, gladly following after her, settling down beside and slightly behind her, lips pressed up to her ear. "And with how rude you're being to Harry, then I think you should ask politely for your answers."

"Let me see i-" Pansy cut her self off, the groan quickly spilling from her lips, one that she had to pull back from, trembling as she hung her head down lowly. "Please, Harry, may I see your penis? I-I can't think of any other reason that-" Once more she stopped herself, the passive aggressive remarks about how he was just some loser Gryffindor doing her no good, and also so far removed from true at the moment. So instead, she said, "Please," a second time, to the delight of Hermione.

"Of course," Harry said, undoing his jeans and reaching down into them. There were few things in life that had satisfied him quite as much as seeing the shock grow across Pansy's face as the bratty Slytherin came face to face with his cock, so long, so thick, so magnificent. Clearly the best she'd ever seen, and she couldn't even begin to think about hiding her reaction as she stared at it. "There are some other reasons that girls like me and are willing to share, but you can't really argue with this one, can you? I keep the ladies satisfied. All four of them, although if you play your cards right, maybe it can be five."

Pansy shivered. "Wow," was all she could muster, gulping audibly as the intimidating shaft in front of her was much, much larger than she was used to seeing under any circumstances. "It's so much bigger than any of the other boys I've ever see." Her cheeks burned as she confessed that fact, shivering as she closed her eyes, only to open them again a second later, realizing she had stopped admiring the magnificent cock. She had a casual thing going on and off with Draco, nothing serious and all very mood dependent, but Harry put Draco to utter shame. "Harry, you're-"

"Hung enough to make you scream," Hermione said, interrupting Pansy, almost getting impatient herself now. "Go on, you can touch him. I want to see you suck my man's cock. Like he said, if you do well, we wouldn't mind sharing, and I'd like to see if you're all talk, or if you can perform." She spoke in whispers, pressed right up to Pansy's ear, shooting shivers up her spine that ensured she could not possibly fight against the urges upon her. In that regard, everything was still going perfectly to Hermione's plan. She was quickly realizing that Harry had amazing leadership qualities and that he was a very accomplished wizard in a raw power sense, and in a duel he was clever, but he needed brilliance to back him up, and there seemed no better strategist to help guide him than her. "Come on Pansy, open your mouth wide."

Leaning slowly forward, the entranced Slytherin grasped the thick cock, gasping as she felt it throb in her hand. The burly black-haired boy in front of her remained firm and steady, hands at his side as he encouraged her onward, wanting to see how she would go at him naturally. So she pushed forward and did her best, opening her lips and taking the head of his cock into her mouth, slowly and steadily sinking forward. It was all about exploration for the awestruck Slytherin, who did her best to try and give him anything approaching a competent blowjob, even if she had no idea what she was doing. "I don't know how I'm going to do this, but I promise to try my be-glurk!"

Pansy's eyes went wide as a hand on the back of her head drove her brutally forward, Harry's cock slamming down her throat and making her gag as her lips were pushed right up against the base of his cock. A wickedly smirking Hermione got a firm grip onto her hair as she pulled her head slightly back, only to push forward even harder again. "Oh, I think you'll take his cock down just fine," the brainy girl teased, feeling vindication as she got down and dirty with a steady, somewhat brutal punishment to Pansy. She had suffered too long at the hands of her bullying, and as much as she was willing to invite her in, both for the good influence of their presence and the need for a spy, she wanted a little bit of vengeance first, and what better way to get back at Pansy than to push her way too far into sex with someone as monstrously hung as Harry was. "And don't worry, since we're going to be the best of girlfriends, I'll do my best to help you."

Back and forth her head was dragged, Harry remaining still and smiling wide as he looked down at Pansy, whose gaze was right up at her. She didn't know how to feel, slimed and cornered and now facefucked brutally, because at the same time, the cock she was slurping on was so big, so wonderful, and even better than that, there was the promise of more if she did well. It seemed 'well' was abstracted out, left just needing to stay conscious and sucking along as Hermione choked her out with her boyfriend's cock, and she hoped that the more wasn't all a joke, that he could stick that massive thing between her legs too. It was a twisted delight, a thoroughly fucked up way to look at the situation, but she couldn't help herself as she shivered on her knees.

"Your mouth feels great," Harry groaned, licking his lips as he stared deep into her eyes, before shifting over to Hermione. His best girl's face was right up by hers, a wicked smirk on her face, and there was something engrossing about her reaction. It was making his cock throb deep within the tightness of her throat as she gagged away, the sloppy facefucking a nice change of pace. He was used to giving it rough to Hermione, who could slobber and drool with the best of them, but who was too used to it. With Pansy, he got savour both speed and struggle all at once, groaning and squirming in utter delight as she went at him without a care. It felt amazing, and even better still than all of that was the fact that the Pansy plan was all going perfectly, and that soon, he would have his spy, not to mention a new girl on the side to play around with.

As much as it should have been worse, Pansy didn't take long to get used to it, even coming to love the tug on her hair as Hermione dragged her head back and forth, taking her face and giving her a thorough, brutal pounding. Her hands had fallen limp at her sides, and it wasn't long before they started to creep inward, pulling her skirt up and pulling her panties aside so that she could get to her aching twat, rapidly getting soaked from the delight of his touch. It was all too much, too confusing and strange, but as much as she had no idea what was even happening any more or what this all meant, the pleasure stuck out like a beacon in the darkness, and she simply followed it.

The trail led in the end to a heavy release from Harry, who groaned harshly as his cock erupted. Hermione knew all of his tells by now, and sharply tugged Pansy back hard enough to make her howl as his cock twitched and spewed forward, gushing thick ropes of sticky hot cum all over her face. An appalled, shocked Pansy got the biggest facial she could have ever imagined, eyes wide and breath heavy as she felt all of the warm spunk upon her features. "F-fuck," she gasped, shivering as she pulled her hands away. "What the-how is your cock so big?" She then turned to Hermione. "And how can you take it."

"I'll show you," Hermione purred, hands reaching quickly down to pull up Pansy's skirt. "Tear her pussy open, dear. I think after that performance, she's earned an induction into our little harem."

"Nngh, yes, please," Pansy gasped. "Fuck me, Harry. I promise, I'll never be a bitch to any of you again, I'll play nice, and I'll..." She trailed off, gulping as she looked pleadingly up at Harry, as Hermione sat behind her and pulled her back, readied her to be braced down, lying against Hermione and ready to get fucked raw.

In a flash, Harry was on his knees, grabbing her ankles and pulling her legs up, shoving her knees against her shoulders, practically folder her in half before he drove forward, burying himself balls deep into Pansy with a single, intense thrust. There was no more playing around now; he was going in for the kill, finishing the job and locking that pussy down. It was all he could do to make sure he got what he sought, groaning as he slammed into her. "Fuck, you're so tight, Pansy," he groaned as Hermione pulled back, letting him shove her down onto the cold bathroom floor, coming in from above to hammer down into her. His thrusts didn't take long at all, and her tightness was not an obstacle in his pounding as he drove unerringly forward.

"She won't be for long," Hermione purred, leaning down and kissing Pansy. As shocked as the Slytherin was, she was so gone by that point that she didn't even think about the fact it was a muggleborn's lips against hers, or that she was entering the blood traitor's harem. She just savoured the attention, moaning into Hermione's lips as the brutal, sloppy thrusts worked her over. It didn't matter anymore what she had to do or what was going to come of it, she just wanted pleasure in every form she could get it, and it stood to reason that Pansy was going to be spending time with Harry's other girlfriends plenty, too.

"Oh, fuck me please," Pansy howled, even though she was on the receiving end of quite the fucking. Harry was in incredible shape, and his strength allowed him to go at her savagely, the writhing Slytherin pinned down and pounded senseless, as Hermione's lips were replaced by her fingers. Fingers that she carelessly began to suck on, not even thinking for a second about saying no. She felt too good to stop, too good to refuse any touch or any affection. It was a powerful sensation upon her, a needy, thrilling swell of delight that left her rattled and gone absolutely mad. Pleasure like she never knew before was blowing her mind, and it was the kind of fuck that could pull someone from their habits, give them second thoughts and reconsider a lot of what they had done. Which was perfect for the purposes of her two assailants, whose true intentions she didn't yet know, but which she would soon find out.

Hermione was surprised by just how eagerly Pansy sucked on her fingers, the facialed and whining girl taking quickly to all of the depravity that had been thrown at her. The plan was shock and awe, but it had worked much better than expected, and instead of complaining, Hermione savoured it, thighs rubbing together as she watched jealously at the savage fucking Harry was giving her; she knew that the second they were alone, she was begging for this very thing, and wouldn't even be the slightest bit sorry about it either. It had been too long since he'd fucked her like that, truly animalistic and feral. Dropping down deep, Hermione whispered into Pansy's ear, "You're a lot sluttier than I thought you would be, but that's okay, I think I like you better slutty. And I promise that you and I are going to get into all kinds of dirty, whorish fun together soon." What she neglected to mention was how much she wanted Pansy to be the whore in question, closing her eyes and imagining Pansy eating Harry's cum out of her pussy between multiple rounds of fucking. The Slytherin would be the only lowly one in the room.

But it didn't matter to Pansy, whose body throbbed and swelled, who was so overwhelmed with sensation as a grunting, groaning Harry fucked her loose that she lost her mind. Release came hard and powerfully to the needy girl, who whined around the fingers, eyes rolling back as her orgasm hit her, as her pussy tightened one final time around Harry, who drove balls deep into her and remained there, pinning her down and grunting as he marked her as his in the most effective imaginable way; pumping her full of his burning hot spunk.

"Fuck, you're amazing," Harry groaned, cock slipping out of her pussy, and like a good girlfriend, Hermione was quick to lick some lingering dripping from his head. "Pansy, I was very wrong about you. You're a pretty great girl, actually."

"Nngh, and I was wrong about both of you. Oh, now I feel really bad about this, I... Th-there's something I should tell you." Seemingly about to hear what they were after, Harry and Hermione both looked at her. "Draco's father is... This is really awkward, but the Malfoys are very high ranking Death Eaters, and Draco receives letters from them sometimes. Updates on the cause. There's a few other Slytherins who do. Not my parents, but... A lot of times, they get read in the common room as a way to boost morale among some of the more extreme students who are into the cause."

Before the two Gryffindors seemed the most ripe opportunity they could have ever hoped for; the thought of asking Pansy to play spy felt awkward, like they would need to broach it over several sessions, but here she was spilling the beans. She didn't even need to go fishing for information, apparently it was being thrown around. They were about to speak, when she continued.

"But I'm not like that. Not really. It's complicated, but killing people seems really extreme, and-look, I don't want you guys to think that I'm one of them, especially now. What if I reported back about the information, and played your ears in the common room and kept you updated about what's going on?"

A great gift had just fallen into Harry's lap, and he began to wonder just how much luck was on his side as his prospective spy offered to turn double agent all her own, before cum had even stopped leaking out of her.
