Madam Pomfrey and Lin worked over the injured Caley. Harry, now healed himself, watched as the two worked frantically to save her.

'I'm going to kill him, I'm going to kill him, I'm going to kill him!' Harry thought in a mantra about what he would do to Snape for this.

"She's going to be okay, but she better not duel someone of your power level, Potter, or her core will go critical," the mediwitch explained.

"I understand," Harry replied, now calmed from Hermione's touch.

"Don't let her leave until tomorrow. She needs to rest," Pomfrey said and Harry nodded.

"Ugh, what...damn!" Caley shouted sitting up. However, the action caused her world to spin at a break neck pace and she laid back down.

"Take it easy, you're as stubborn as a bull," Hermione let out.

"We've got the same phoenix core don't we?" Caley asked.

"Well, I'm glad to hear that there's a brain under all that hair," Hermione huffed.

"My hair..." she began but Hermione stopped her.

"Trust me, if you are as vane about your hair as I think you are then you don't want to know until you can do something about it. Madam Pomfrey said you can't be moved until tomorrow and not to get into any more duels with Harry. Your core can't take it."

"And where's that male whore anyway?" Caley asked.

"So, I'm continued to be punished for my actions," a ghostly voice said. The two girls turned to see Sirius Black standing looking quite remorseful.

'Nice," Hermione sent to Harry and quietly and quickly slipped out of the room.

"What...who are you?" she asked having not seen this particular ghost.

"I'm your dead father," Sirius answered.

"What? How is that possible....the stone."

"Just like your mother, cleverest lion of my time at Hogwarts."

"And why are you here?"

"To talk to you. And if you are going to ignore me then I'll just bother you until you actually cool down and listen. Although, you get that from me."

"Bah, the only thing I get from you is my hair color."

"True, but your mother was an owl animagus, and I was a dog, so your abilities come from the both of us."

"So, you knew her abilities that well enough before you shagged her?"

"Have you ever been a teenager during a war?"

"Have you ever been working for an old bastard like Grindelwald?"

"Dumbledore is close enough," Sirius remarked with a smile.

"I'll have to give you that, they both seem to be two sides of the same coin."

"Now you see, how hard was it to not say a harsh word to me?"

"Shut up," she growled.

"You know you can't continue your mission. You keep going after your head of house then your core will continue to become more unstable."

"Like I've got a life to live. And why am I so effected? I'm not part of House..."

"Ah, but you were never found out by either of my parents. No one has known until now. The only reason the goblins didn't put the ring on your finger is because I swear that I didn't know your mother was pregnant."

"Right, like I believe that."

"Seriously. I lost contact with her after we graduated. I don't know what she was doing but the next thing I hear was of her death just before James and Lily were killed by that bastard."

"Like I should believe that."

"It's true. You've gone lesbian haven't you?"

"Why would I do that? I find witches just as bad seeing that they can't stand up for themselves against pricks like you and Potter."

"I'm a prick, but my godson isn't."

"You would stand up for him."

"All his witches are willing participants in their shagging. Plus, you should know that your attraction towards him isn't normal."

Caley bit her lip, "A veela?"

"Close enough, but I'm not telling," he said with a grin.

"If you think this will change my mind..."

"Think, would he have left you there dying if he was a prick?"

She bit her lip again and sighed. Potter had a saving people thing that couldn't be ignored. The ghostly vision of Sirius faded and she sighed and fell back asleep again.

"This...well...I don't have the words to even to describe what you want to try to make," Slughorn said looking over the roll of parchment that laid out Su's proposal.

"It took countless hours of research into putting that together," Su explained.

"This is good, Miss Li. The quality of the research here is top notch. You have my permission to start your work on this."

"Thank you professor," Su said gratefully and left the office, traversing her way back through the winding hallways of the castle.

She made her way confidently through the corridors of Hogwarts until she heard several sets of footsteps approaching her.

"Well, if it isn't one of Potter's birds out for a stroll," Nott taunted.

"I was with your head of house, Nott. Now, will you let me pass or is there something you actually want?" Su inquired annoyed.

"You bet there's something we want," Draco said with a vicious grin. Crabbe and Goyle took a few steps toward her, reaching out for her arms.

"What is this?" Su asked as Draco's two henchmen wrapped their thick fingers around her slender arms, squeezing tightly and making Su realize what they wanted. The Ravenclaw braced herself and focused her magic, preparing to defend herself.

"Your body belongs to us," Nott said with a smirk as Crabbe reached up behind her and started groping her through her robes, his hands clumsily and roughly pressing into her chest, obviously never having had the opportunity before. He and Goyle must have gotten their dicks sucked by Malfoy's and Nott's groupies on a regular basis, but that's as far as they probably got.

"Ouch! You big lummox! If you're going to try to seduce a girl..." in a flash, Crabbe was on the floor writhing in pain, his wrist singed by her firm strike, "then at least learn how to do it properly!" Su growled as she kicked the first of Draco's cronies square in the stomach, glaring at Goyle. "And you had better let me g-" she started just before she received a hard backhanded slap to her cheek from Nott, making Su gasp and stumble against the wall, holding her palm against the rapidly reddening spot where Nott's large, rough hand struck her.

"Shut up, bitch! Little Ravenclaw cunts like you need to know their place! Slytherins certainly do!" Nott growled, reaching down and pulling Su up from between her legs, her back rubbing against the wall as his large, rough hand pressed firmly into her crotch, lighting her senses on fire and making her bite her lip, struggling to maintain her composure, muffling a soft moan before Nott raised his hand to strike her again. "What was that, you little cunt?" Nott grinned demonically as he rubbed his fingers together, feeling the trace of juices that he'd picked up from her pussy.

"I'm not so defenseless," Su growled, the "fight" half of her "fight-or-flight" instinct having faltered momentarily. In an instant, the nimble girl's reflexes had produced her wand as she shouted "STUPEFY!" and aimed at the group, sending a wave of magic out and knocking Draco flat on his back, Goyle and Nott struggling to stay upright as they stumbled a few steps, giving Su the opening she needed, ducking under Goyle and Nott's reach, jumping over a stunned Draco and clutching her parchment tightly before sprinting away from the quartet of Slytherins, quickly gaining distance.

"Get her!" Nott shouted and the snakes started the chase, Goyle helping a disoriented Crabbe up as Nott bolted after the faster Ravenclaw, her physical training the best advantage she had over superior numbers.

"I'm regretting my decision, 'Mione," Harry began, "I am losing control of that part of me."

"It's the sex...you need it and we cant do it as much because..." Hermione began.

"Because that sodding bastard has got the portraits, ghosts, and house elves watching everyone just to make damn sure that no one has a chance to have any," Harry finished with a growl.

"I can't believe I'm about to say this but I think we might ought to leave and not come back. You can give Neville marching orders so he can deal with Snape and we continue to battle Voldemort elsewhere."

"No, then Dumbledore will win again and I can't...I WON'T let that happen."

"Where's Su? She should have...bloody hell!" Hermione shouted looking at the map. Cursing at himself for being distracted and not noticing her situation himself already, Harry exploded into action by phasing away.

'Crap, he's not going to escape this one unscathed.'

888

"Damn bitch!" Nott roared, leading the charge as Su literally rebounded off a wall and made a hard turn, skidding around the next one and hiding in the shadows.

"I must say, you snakes don't give up, now whether or not that's because you're too stupid to give up is still left to be seen," Su replied, her voice echoing off the walls, Nott's group unsure where exactly she was. As she slowly backed into the shadows to flank the four, she heard a rustling sound and saw a rather well-sized rat scurry away, making her shriek briefly before she covered her mouth, forcing herself quiet.

"Get her!" Draco barked to Crabbe and Goyle, the two mountains of flesh stopping seconds later as the air before them shimmered and exploded, knocking the both of them out and forcing Nott and Draco to cover their eyes.

"Take one step further and your dead," Harry growled, his wand pointed straight between Nott's eyes, Su stepping out as Harry wrapped an arm around her in a protective embrace.

"Potty, what a surprise. How did it feel to almost be beaten by a witch?" Nott asked.

"Ok, which one of you idiots thought it would be a good idea to try and touch that which isn't yours?" Harry growled, ignoring Nott's attempt to get a rise out of him.

"Please, do you not think because of my father's new found favor that I wouldn't be given a task to harass your harem?" Nott asked.

'I'll kill your father first,' Harry thought.

"What is going on here?" Snape asked after appearing from around the corner, his figure seeming to almost blend into the darkness and shadow.

"Nothing, we were just leaving," Harry spat and phased away, not wanting to have another encounter with the headmaster after the D.A.D.A. class so recently.

888

"They are after the students in the harem, are you sure we should stay?" Tonks asked.

"I don't know anymore," Harry lamented. "Su's fine, but that's because she was able to beat back the Slytherin bastards. Part of me wants to leave to protect those that are still attending class, but that other part of me that doesn't want to give Dumbledore and Snape the satisfaction. Either way though, I've got this feeling that the final fight will be here."

"Harry," Padma said coming over to him, "The diadem..."

"The diadem? You mean Ravenclaw's Diadem?"

"That's what Luna said."

"The room of requirement...I'd bet the entire Potter fortune it's in there." Harry remarked with a smile. "I'm going to check up on Su. When Hermione and the rest get back from class inform them about Luna's findings. I'm going to prove once and for all that Dumbledore was wrong," he said and headed for the bedchambers.

"He's not in a good mood is he?" Padma questioned the three, Tonks, Cissa and Bella.

"No, and to add to that Anastasia and Lin want to get pregnant. I'm tempted to join them, but so much shite has hit the fan that I don't know if that's a good idea at this point," Cissa said.

Harry's firm footsteps echoed off the cold stone walls of his sleeping chambers. Since adding to his harem, he and Hermione had worked to adjust the room to fit each witch comfortably when they chose not to sleep with him. As he walked down the long room towards the door at the end, which lead to his private room that he shared with Hermione on most nights, Su was sitting on the end of her bed, somberly looking down at the parchment in her hands, a few tears marking dark spots on the old-style paper. She looked up when she heard Harry's footsteps stop in front of her.

"I wasn't...I wasn't strong enough, Harry. That slimy bastard Nott put his hands right on me. That and Crabbe trying to rip my breasts off..." she sniffed, wiping away a tear as she looked up at Harry, anger, frustration and a bit of shame running behind her irises.

All Harry could do to contain himself was sit down next to Su and wrap her tightly in his strong embrace, feeling her warmth against him.

"You were wonderful, Su. You managed to put down one with your martial arts and then knocked both of Draco's cronies out with a single spell. Next time I get Nott alone he's going to have to grow himself a new hand," Harry spoke softly to her. "I'm very proud of you. You've certainly gotten stronger since you first arrived."

Su looked up at him and smiled weakly, sniffling before she nodded and wiped her eyes. Harry's proximity to her made her thighs shift, feeling warmth and wetness between her legs. Harry sensed Su's steadily increasing arousal and felt his demon coming to the surface. Sighing, he relinquished control to his darker side.

"Su...when that snake touched you, did you get wet?" Harry said, his voice slightly darker, shadows seeming to cover his eyes.

"Y-yes..." she blushed, ashamed that her body had betrayed her. "I didn't want to be...but with Snape's new rules and our limited time we can be together...I've been getting wet every night. I've been using the toy I got in Diagon Alley. I've been so horny I've had to masturbate three times a day!"

Harry gave a slight chuckle, his erection beginning to throb between his legs. He could feel every drop of sperm in his balls churning and moving, his demon-tainted seed aching for release. Harry slipped one hand down between Su's thighs, feeling the slight wetness between her legs.

"Is that from Nott?"

Su nodded slightly, blushing. "I wish it wasn't. I feel like I need to rub myself in cleaning alcohol to get his filth off of me!"

"No need for that, Su. I'll take care of you. Actually..." he paused, a wonderfully erotic thought crossing his mind, "you'll take care of you."

The Ravenclaw's eyebrows cocked as she looked up at him. "What do you mean?"

"Let me show you," Harry grinned, then stood up, the tent in his pants throbbing in front of Su's eyes. "Suck on my cock, Su. But when I cum, I want you to rub it into your chest."

Knowing to trust Harry's judgement, the younger Li nodded slowly, then smiled and reached inside Harry's cloak, gasping as she unzipped his pants and felt his hot erection pulsing, heat and lust literally radiating from him.

"Ooooh...hello, there," Su cooed before she wrapped her lips around his tip and started sucking on his massive erection, her tongue flicking over his tip, tasting his precum already beginning to flow liberally. She started taking off her clothes one layer at a time, pausing her ministrations as she lifted off her t-shirt, making Harry shudder as cool air wafted over his moistened length. As she stripped down to just her white lace knickers, the high-cut fabric revealing the smooth skin along the inside of her thighs and just barely covering the sides of her swollen pussy, Harry saw the fabric slowly becoming more sheer as her juices flowed from her pussy, the skin around it glistening with a light sheen of her lubricant. She looked back up at Harry, his cock pulsing in front of her, the scent of his musk making her cunt ripple, aching for something big, thick and hot to fill her before her lips wrapped around Harry's length again, swallowing methodically as she managed to make all but the very base of his cock disappear.

"Mmmm...that's my good girl," Harry moaned, feeling the tip of her tongue tracing around the opening at his tip. He quickly felt himself coming to climax, having pent up so much frustration and lust that his demon was completely letting go. A few minutes later, Su felt Harry's cock pulsing and hardening in her hand. She used that as a cue to pop her lips off of his erection, continuing to stroke him, his erection covered in a mix of her saliva and his precum. Seconds later, Su watched with fascination as Harry's heavy, swollen balls began contracting in his scrotum. Smiling mischievously, Su reached up and wrapped her thumb and forefinger around the base of his sack and gently tugged down on it, prolonging Harry's buildup, making him moan and growl.

"Are you ready to cum?" Su asked after she stood up, whispering into his ear. That put Harry over the edge, his demon pulsing and growling as his body shuddered and tensed as Su knelt and stroked him as she let go of his scrotum, Harry's cock pulsing and swelling as the first of many spurts of hot, thick cum erupted from his tip, flowing almost uninterrupted as his testicles emptied of their seed, Harry gripping his base and guiding his streams of potent cum all over her breasts, covering her soft, pale skin in several layers of his essence, which slowly began to disappear as Su's hands rubbed it all over her body, absorbing into it.

Su shuddered as she felt her body growing increasingly warm before Harry stood back and a glint flashed behind his eyes, Su's body writhing as her back arched violently, her breasts jutting out and her nipples rock hard. The Ravenclaw was in a high of orgasmic bliss as she squeezed her breasts, feeling dribbles of milk flowing down her sides as her pussy clenched and fluid squirted from between her legs. As her fluids collected on the floor in front of the bed, Harry stroked off his cock and shook a drop of his cum loose from his tip, his seed dropping into the center of the sizable puddle before he brushed his fingertips over Su's milk, shaking a few drops into the puddle again before he licked his fingertips. As Su came down from her orgasm, her thighs still quivering, she looked at the end of the bed and saw something that made her both incredibly frightened and aroused.

Standing between Harry and Su at the end of the bed, created from the very essence of Su's and Harry's bodies, was a doppleganger - a demonic copy of Su. The Ravenclaw shuddered to think that Harry had this kind of power. The doppleganger smiled, flashing her demonic fangs that differentiated her from her human original. Two small horns sprouted from the top of her head, forming little points that were just visible above her jet black hair. The doppleganger's skin was dark in contrast to Su's own, an inhuman bronze color, as if it was covered in excessive layers of artificial bronzer, similar to that of Japanese ganguro girls. The biggest, difference, however, was between her legs. The doppleganger's dark, black orbs looked over Su's pale, soft body and grinned, a lustful aura radiating from it, making it's dripping pussy flow and spread wide as a thick, swollen penis appeared from within, identical to the size and length of the half of the toy that Su had been using.

"Harry..." Su mumbled, frightened and unable to look away from the throbbing cock between her demonic copy's legs, "what is that?"

Su watched as Harry's eyes shadowed further and his cock seemed to drip endlessly with precum, spattering over the floor and steaming as it hit the cold stone beneath his feet. Something shifted in his voice as he spoke.

"Don't you recognize your own body, my little pet? I used my powers to create a copy of you to help you rid yourself of that cockgobbler Nott's filth. My succubus here will provide the perfect revenge on Nott and his ilk. All it needs is a small tribute of your juices and milk to disguise itself to be passable as a human long enough to perform its mission."

The succubus spoke softly, her voice echoing demonically as it looked at its original. "Don't be afraid. I won't hurt you. It is not my way. I feed on the essence of weak, corrupt males. And from what I gathered from when my master created me, there's plenty of that for me to feed on," the demoness smiled, almost reassuringly as she knelt on the bed and approached Su, who hadn't moved in the last few minutes from sheer terror. The succubus crawled over top of Su's frightened body and kissed her hungrily, the Ravenclaw feeling her pent-up lust draining from within her while more of it grew as the succubus' girlcock brushed against her inner thigh, coating it with precum. As her darker version broke her lips from Su's own she gasped and looked back at Harry.

'Merlin...is that what I look like? No wonder I'm getting jumped by Nott!' Su erotic thoughts betrayed her desire.

"Harry...is this wise? Releasing a demon upon the school simply to exact your revenge? Is this...really the best thing to do?"

Harry's smile flashed again and he chuckled, his throbbing cock and steadily swelling testicles bobbing with the motion, clearly showing that his demon was gaining more control of his body.

"It is precisely what they deserve, and precisely what you need to cleanse them from you. Now then, lay still and let my little succubus collect what she needs from you. She's actually quite talented. She's had all of eternity to perfect her technique," Harry's smile flashed again as the succubus got off of the bed and gently caressed Su's cheek, her touch feeling like it was burning her skin. "And I'll be right here with you the whole time," he finished as Su's doppleganger's seductively walked to its creator, reaching down and stroking Harry's demonic erection, kneeling before him and wrapping its lips around his demon-tainted shaft and sucking hungrily. As it did so, Su watched with aroused fascination as her copy suddenly sprouted a long, thin, flexible tail with a flat, pointed spade on the end that swished back and forth, finding its way between Harry's legs and caressing his distended, swollen scrotum as she drove two fingers into her own pussy, making the succubus moan with lust.

As Harry grunted, his seed spilling into the succubus' open mouth, Su watched as her doppleganger's breasts swelled and began leaking a milky purple substance. After kissing Harry's tip, her belly full of his cum, Su's copy walked back over to Su, the cock that had sprouted between her nether lips having swelled and grown even larger, veins clearly visible along its length, the tip of it shining with precum.

"Prepare yourself, my dear. You'll feel better in no time at all."

Su merely swallowed audibly as the succubus smiled lovingly at her and felt her thighs quivering, her pussy clenching rapidly, aching for something to fill it.

The only thought that ran through Harry's suppressed emotions, buried deep down under his demon, was this: "What have I done?!"
