She goes after Draco disguised as a futanari slime girl

Hermione took a moment to play around with her new transformation power. By forming an image of herself in her mind she was able to change it and when she did those changes occurred to her body as well. She made her breasts swell in size until they were up to D cups. She enlarged herself until her head was brushing against the ceiling. She couldn’t help but moan in sinful delight as she changed herself. Her skin felt like it was on fire as it stretched and shifted. Her breasts felt all tingly and wonderful as they were enlarged. A core of heat settled in her gut as she felt powerful and godlike. She couldn’t help but fondle herself as she changed, letting her hands roam across her body as she reveled in the sensations that were overwhelming her.

A thought crossed her mind of another way she could enjoy herself and as soon as it did she grew a large, thick heavy cock that dangled down to her knees. Her hands wrapped around it almost instinctively which made lightning dance up her spine. She started rubbing it back and forth as she felt it pulse and fill with blood. When it stood to attention it lifted all the way up to stand between her breasts. She pulled its foreskin back and leaned her head forward to lick and suckle on its tip.

She squealed in delight as pleasure filled her mind, enough to make her go cross eyed. She drooled over it as her hands left it to squeeze her breasts together over her shaft and her hips began to thrust forward. She was fucking her own breasts and drowning in the overwhelming bliss of it all. Suddenly she understood just how the boys she knew could be so obsessed with sex if this was what they got to feel all the time.

It didn’t take long for a feeling of pressure and tension to develop in her new cock. It only made her thrust, rub and suck harder. Moments later she exploded into her own mouth. Shot after shot of delicious cum filled her mouth as she eagerly swallowed it down. She moaned and squealed with the orgasmic bliss that filled her and almost fell backwards as her body was rocked by waves of intense pleasure and overwhelming sensation. She felt like she swallowed gallons of her own cum. Finally the feeling of bliss began to relent as her cock went soft and fell down to her knees once more.

Suddenly the thought of what she was doing gripped her. She was a towering figure standing in the open in the school library, naked and pleasuring herself. Her face went crimson as she looked around. Luckily it was fairly late at night and the rest of the library was deserted. But she quickly shrunk herself back down.

Oddly she didn’t completely return to her normal size. Her shrinking stopped when she was a mere seven feet tall. It appeared her Amazonian body was her new default. But that was fine with her. She also allowed her breasts to settle at a more reasonable C cup rather than a D. She kept her new cock though, she didn’t want to ever give that up.

As her sense of panic and embarrassment subsided she still felt a smoldering fire insider herself. She was still a little horny and eager for more pleasure. The thought of returning to Gryffindor tower held little appeal to her. She wanted to try out her new rules a little bit more. She decided to go hunting after Draco.

She looked back over the rules she had written and realized that because of how she had written them there was an odd interaction present. Her fluids, namely the spunk she had every intention of filling him with, would make Draco addicted to her, but he didn’t necessarily need to know it was her he was becoming addicted to. If she assumed a form he didn’t know she could have all the fun she wanted **** him and afterwards Draco would start to fall in love with her while having no idea that she was the one forcing these feelings on him.

The thought of Draco eventually coming to her out of the blue and begging to be made her pet out of what he believed was his own volition was deeply appealing to her. And she couldn’t help but think of all the images and posts she had seen online this past summer. Muggles had quite the imagination when it came to envisioning fantastical creatures and quite a lot of them enjoyed depicting said creatures as beautiful girls. She could easily make herself into one of those monster girls and use such a form to hunt and torment Draco until he came to her as a hopeless addict to willingly become her pet and her toy. Oh this was going to be so good.

She added one last rule granting her the power to magically store away things and people in a pocket dimension. Which she then hid her clothes, wand and the rule book safely within. It wouldn’t do her any good to move around disguised as a monster while wearing a school uniform and carrying any of her personal affects that might be recognized. Then she thought about a suitable form to assume.

Should she overpower Draco as a minotaur? Entrance him as a siren? Steal him away as a giantess? Wrap him up as some tentacle monster? Run him down as a werewolf? So many tempting options. She ultimately concluded that for this first encounter she would try and take him by surprise. And she now knew a very sneaky way to get into the room of requirement.

Hermione formed the image of herself in her mind and applied her desired transformation. Her skin turned goopy, her legs fused together and she sank slightly as her feet and calves turned into a small pool of blue liquid. Her hair was replaced with a gelatin mass and her whole body changed to be a dark blue color as it all assumed the same texture. She had made herself into a slime girl.

It was a very strange transformation, her body no longer had any real distinct parts. She still had eyes but she could see from any patch of her skin. She could freely choose to either look out from only one part or too see everything around her all at once. It might have been disorienting but she found she had no trouble processing it all. She had a single tongue in her mouth but she could taste everything that touched her skin, from the floor to the air to her own goopy body whenever she touched herself. She could feel her own insides and tell she no longer had any organs. She could breathe through her own skin and could process all the scents in the air much more clearly. Her mind seemed to be working faster to process all this new information, so it appeared that every cell in her head could now act as her brain.

She touched her boobs experimentally and found she could choose to make her skin permeable or hard to the touch. She was able to freely fondle herself, which felt incredible, almost as good as jacking off had. She could also allow her breasts and hands to fuse together, or keep her hands solid to reach inside of herself.

Her body was also highly malleable now. She could stretch out her arms into long tendrils that could reach great lengths. She could firm herself up into a perfect copy of her previous body. Or she could allow her form to become indistinct and slip down into a ball of slime or even a puddle on the floor. She could increase the mass of any part of her body, inflating her boobs at will, but unless she pictured herself growing larger with her transformation power she had to borrow her extra mass from some other part of her body.

The only part of herself that was still distinct was her cock, which remained more sensitive than any other part of her body. It was also the only part of her that refused to become permeable, as it remained hard and firm whatever she did with it. She could stretch it out though into a long tendril and move it back and forth like a limb. She also found she could make copies of her cock which gained all the same properties of her main one, save that they couldn’t grow any larger than her first. Oh yes this body would be a lot of fun to play with.

To complete her disguise she erased all the features of her face making it smooth and she straightened her hair out to hide its natural frizziness. Then she allowed her body to sink down into a pool of dark slime so she looked more like a shadow hanging on the floor. After that she left the library and began making her way to the room of requirement.

Hermione moved very quickly. Every part of herself could grip and push against the ground beneath her. Experimentally she climbed up the walls and found she could cling to the ceiling without any trouble. She passed right over the head of Filtch and Mrs. Norris, a completely unseen shadow on the high ceiling. She almost laughed to herself over how easy it was. Hogwarts was now her hunting ground, nothing could stop her from reaching any of her playthings.

The door to the room of requirement did not appear for her since it was in use by Draco. But the room itself was still present on the other side of the wall surrounded by magic that enlarged its space to be whatever someone needed it to be. So Hermione was able to slip through a crack in the wall with her near liquid body and flow into the space beyond it.

The room itself was rather boring, mostly empty space. The only things that caught her eye were a pair of magical work benches, a book shelf in one corner, a large cabinet standing in its center and of course Draco Malfoy himself. The Slytherin boy was standing in front of the cabinet, waving his wand back and forth as he slowly chanted magic over it. Hermione glided silently across the floor, slowly surrounding Draco’s feet. She listened to him work for a time, curious about what he was up to.

From the sound of the spells he was chanting he was trying to fix the cabinet. For what exactly she could only guess. Some of the spells he said sounded like they were related to transportation. Was he preparing some sort of magical escape route from the castle? Or perhaps a way to bring people in instead? Well it didn’t really matter. Soon all he would be concerned about was how to please his future mistress.

Hermione brought her slimy body into contact with his feet. She held them in place and started slowly crawling up his legs. As her slime began to seep into his socks, Draco finally noticed that something was happening to him. He tried to pull free from her, but Hermione easily held him in place, so he lost his balance and fell backwards.

He landed in the rest of her body allowing Hermione to start crawling up over his arms and chest as well. He panicked and tried to fire a stunning spell back into her but she simply refused to allow his magic to effect her. He tried a few more powerful spells but it was useless, it was a bit annoying though. Hermione ran her slime up his wand arm much more quickly and pulled his wand out of his grasp. Now there would be no more magic to resist her.

Hermione raised herself up with Draco still trapped with in her. She pulled him down into her body so that only his head was free of her slime, trapped between her breasts. She firmed herself around the rest of him, holding him in place. She pulled his arms and legs aside a bit so he was spread eagled inside her. She also enlarged herself enough so there was still a few inches of slime between his outstretched arms and freedom. He looked so utterly helpless trapped in her belly that she couldn’t help but giggle at him.

“Oh Draco what have you been up to?” She cooed at him, her voice sounding much deeper with her larger size. “Out of your dorm after hours? Playing with some magical artifact? You’ve been a naughty boy it seems. I think I might have to punish you.”

“Who are you?” Draco demanded, his voice panicked and ****. “How did you get in here? Let me go already you stupid monster!”

Hermione didn’t answer him, she just laughed at his **** pleas. She caused the cells around his clothes to release some digestive enzymes and started dissolving his clothes away. She was very careful not to burn any of his skin, she simply stripped him of everything on his person until he was naked trapped in her body. She could taste every square inch of him and found he had a pleasant flavor. She wouldn’t have minded simply holding him like this for a while, feeling his useless struggles, watching his cute little body writhe surrounded by her while she listened to him beg for release. But she saw something that surprised her. Hidden on his arm was a dark mark. Draco had joined the **** Eaters. Now that did need to be punished.

“I am a spirit that guards Hogwarts castle.” She declared. “And you have brought evil into this place. Until you give up on your foolish ways and submit yourself to a muggleborn to beg for forgiveness I will judge and punish you every night.”

Before Draco could make any protests, Hermione caused her cells around his cock to mimic the feelings and function of her vagina. Then she firmed her grip around his pelvis and began to rut his body back and forth. Draco’s breath caught at the sudden stimulation. All his indignation was driven from his mind as pleasure began to fill it instead. He started growing hard inside her.

Draco wasn’t as small as she had expected, in fact he had a pretty decent sized cock. She started to moan a bit as she felt him fill her. Draco was definitely enjoying it too as he began to grunt and tried to thrust in time with her, pushing himself as deep as he could go despite how firmly she held him. A heady sense of power filled Hermione over how easily she had taken control of him. She was quickly growing quite aroused herself.

Hermione shifted Draco around so his pelvis lined up with hers, his legs trapped in her own leaving his head to poke out of her belly. She rocked her hips sensually back and forth so that Draco could thrust a little harder inside herself. A look of smug satisfaction came over Draco’s face, but it quickly faded as Hermione allowed herself to grow erect.

Her towering slime cock stood to attention. It was larger than Draco was tall and his mouth fell open at the sight of it. Because of how he was positioned he was now thrusting into the base of it. Hermione groaned sinfully as she now felt Draco fucking her little slime pussy and the base of her cock. Once more she wrapped her breasts around her monster and began to rub them up and down her shaft as she **** Draco to fuck her harder and harder. Her towering mast of slimy flesh fell on Draco’s face. The heady scent of her musk filled his nose and made his mind go more than a little soft. Despite himself, Draco began to lick at her shaft as it bounced on and rubbed all over his face.

The constant stimulation quickly overwhelmed Draco and with a sudden cry he began to shudder and come inside her. The amount of cum he released was nothing compared to how much Hermione had shot out earlier, but the pathetic sight of him falling to pieces inside of her more than made up for it.

She allowed Draco to fall out of her body as his orgasm rocked him. As he tried to stand up she melted her legs back into a puddle which grabbed hold of his arms and legs, leaving him half raised up in a doggy position. She grabbed his hips as she sank down into herself until her face was level with his rear end. She groped his ass and kneaded at his flesh while her dick reformed as a prehensile tentacle in front of him. She also grew a few extra pairs of hands as she prepared to resume playing with him.

“I think you enjoyed that a little too much my little pet.” Hermione gloated over him. “Naughty boy, you must be a pervert to enjoy it when you’re **** to come. I fear your punishment is only going to get worse because of that.”

With one set of hands she launched an attack on Draco’s chest. She started playing with his nipples. She rubbed them, pulled them and twisted them until Draco was keening in pleasure. She would occasionally open a mouth in her palms, complete with tongue and lips so she could suck and lick at them while she felt up his chest. Idly she formed an image of Draco in her mind to gain the power to reshape his body and then inflated his chest a bit until he had a nice perky pair of B cups for her to play with. She also imagined them as extra sensitive which made Draco begin to cry out in pleasure and bliss.

While Hermione’s new arms worked over his chest, she used another pair to grab Draco’s head. She **** him to look up while she held his mouth open. Immediately her tentacle dick flew forward and **** Draco’s jaw open as wide as it could to begin fucking his mouth. Ye gods that felt so good! Way better than her own tit fuck had been earlier. Draco’s mouth was velvety smooth, tight and wet around the head of her dick. She needed more of this. She started thrusting hard into Draco’s mouth, pushing her cock deeper and deeper into him.

It wasn’t long before Draco was gagging on her cock as she started invading his throat. She paid it no mind and only concerned herself with rutting deeper into him. His throat somehow felt even better than his mouth. It was so tight! So perfect! And the way he would **** and convulse on it made everything even better! She pushed deeper and deeper into him she wouldn’t be satisfied until she could come directly into his stomach.

While she fucked his face, Hermione reformed her mouth and began to lick around Draco’s asshole. She made sure to make his entrance as wet as she could with saliva and slime. Then she **** his entrance open and started properly eating him out. His flavor inside was bitter enough she almost switched off her sense of taste from her mouth, but the way it made Draco squeal and shake more than made up for it. She made her tongue thicker and longer to reach deeper inside of him. She touched one part of him and Draco cried out in sudden ecstasy around her cock. She attacked that spot again and again to make him shake and writhe under her grasp. She was surprised when she felt something salty begin to splatter on the slime beneath Draco.

“Oh Draco did you just come?” She asked without pulling her tongue out of his body, her voice echoing from her skin. Draco shamefully tried to shake his head in defeat. “You really are a naughty pervert. You deserve everything that’s happening to you, don’t you?”

This time she **** Draco to nod his head. He did his best to whine in protest around her dick, but she ignored him. Instead she formed another arm that reached up to fondle his cock as Hermione attacked his sweet spot over and over again until she felt him grow hard in her grasp. Then she formed another mouth like opening on her latest arm, filled that mouth with a copy of her pussy and began to push Draco’s cock into it.

Draco suffered under this relentless **** for what felt like hours to him. Hermione was now chewing on his tits in addition to sucking and licking them. His jaw ached from how wide he was being held open and he could feel his throat going numb. His cock was terribly over stimulated so that every time he was **** to rut his hips forward pain and pleasure in equal amounts shot through his pelvis. His ass was being spread so wide he doubted he would be able to walk properly for days. But despite it all his mind was in heaven.

He felt so weak and powerless that it became a kind of joy to surrender to it all. He felt like a toy and a plaything but there was an odd satisfaction in making this monstrously powerful spirit take such delight in his body. He felt like an utter failure of a man yet every time this thing hit that one spot in his ass he felt lightning dance up his spine and he grew a little more jealous at the thought that girls got to be fucked like this whenever they wanted. Despite himself, Draco soon came for a third time under this monster’s powers.

Not long after that Hermione felt the heat in her loins reach a boiling point. She pulled her tongue out of Draco’s ass so she could throw her head back and scream in delight. Draco watched in mounting horror as the massive cock before him swelled in size before he felt a great bulge **** his jaw wider and rush down his throat. He could feel his stomach expand as shot after shot of hot sludgy liquid filled his belly. Then that dick started to pull itself out of his ruined throat. Another shot filled him back up as it left. And then it was hanging in front of his face as it fired off two more shots and covered his face in white, hot, thick, viscous spunk. With his stomach already full to bursting what had been left in his throat poured out of his mouth and pooled on the ground before him.

The taste of it briefly wiped out all thought from his mind. In fact Draco’s mind was left in a state of pure bliss. Strange chemicals **** their way into his blood stream, ran like lightning up to his brain and began to rewrite vital parts of it while a sense of euphoria overwhelmed Draco. Sights of nubile, naked, powerful bodies danced before his mind’s eye as a thousand voices shouted at him that he was a slut, a pet, a plaything. That the only thing of real worth he could ever do with his life was make himself into the toy of whatever mudblood wanted to take him. And one body danced before him most of all. Hermione Granger, but his mind insisted on referring to her as a goddess he was meant to serve.

Hermione watched as Draco collapsed onto the ground. His eyes were rolled back into his head, his face utterly debaucherous, his body evidently ruined. All he could do was twitch in a pool of her cum. She was tempted to fuck his ass as well with her proper dick. But it seemed he was so mind broken he wouldn’t be able to properly appreciate it.

She eventually decided that could wait until tomorrow. Besides she needed to pass her blessing on to Ron and Harry. They deserved to have this much power as well. And she was curious to see if one good fucking was enough to break Draco completely, or if he would need a few more nights to be properly persuaded.
