Chapter 1 - Visitation

 The students of Hogwarts were just returning after their winter breaks and the bustle of the hallways drifted throughout the school. Though many were excited to be coming back, no one missed them more than Hogs. The old ghost had been roaming around for months in anguish, waiting for his beloved girls to return…

 Few knew about Hogs existence. Indeed, he himself wouldn’t have known to say where exactly he emerged from and how it happened that his spirit form was bound to haunt Hogwarts. It was only a year or two ago that he first found himself there. The other ghosts avoided him on account of his abysmal appearance and poor manners. In life, he had been short in stature, but astoundingly fat, to the point that his buttons often popped and left it tumbling out - which was what was preserved in his appearance now. The only reason he got called “Hogs” was because his first encounter had been with Helena Ravenclaw. He had followed her along for so long and commented on her appearance so many times that polite Helena eventually snapped in disgust: “Get away from me, you perverted hog!” 

 By now, all of the other ghosts were acquainted with his antics and especially his disturbing fondness for the female students. Not the youngest ones - those Hogs ignored with disinterest, knowing they would need to grow up first. He may have been sick, but it was only those eighteen and above that interested him. These shapely and plump girls in their final years were a sight to behold. Many of them tried to hide their curves beneath their robes and sweaters of their uniform, but their inability to do so only stressed how thick their bodies really were. 

 Simply incredible, Hogs often found himself thinking as he stared at the gorgeous beings walking up and down the hallways. 

 One peculiar thing was that the students themselves couldn't see him, though they were used to greeting the other ghosts. This gave Hogs free rein to follow them wherever they went, often intruding upon the dorms as the girls changed into their lingerie and got ready to slip under the cozy warmth of their blankets. The other ghosts always tried to stop him and warn the girls about his presence, but there wasn’t much to do about a spirit they couldn't see. Some doubted that such a Hogs existed at all - especially the ones that absorbed everything about Hogwarts and checked all the books... 

 There were many girls that got the pervy ghost’s interest, but he grew fond of one in particular: Hermione Granger. 

 In general, he preferred the fiery nature of Gryffindor girls. The more he followed Hermione around in her dealings with Harry and Ron, the more he began to appreciate the muggle-born wizard for her quick wit and intellect. So many came from established families, yet she towered over them in mind and spirit. Over time, he began to wonder just what kind of brain was in that beautiful head of hers if she could have gone not only from muggle to wizard, but to being the smartest person Hogwarts ever enrolled and Hogs came into contact with directly.

 The ghost was not at all interested in what the trio were fighting to accomplish, though he would occasionally lend them a hand here and there if he could find the willpower to go through the exhausting effort of imposing himself on the physical realm. One thing he noticed was that his impact on the physical world grew along with his arousal. In the moments that he was most aroused, he could do the craziest things - like open doors, or even tug and lift the skirts of certain students, all happening as second nature in those moments of raw lust. 

 Over time, he began to wonder what would happen if he took things a step forward…

 Whatever he decided to do, he knew it would be with the intelligent Hermione. Why the boys she hung out with showed no sexual interest in her was beyond him; but the ghost knew better than that. Could Hogs exchange places with either one of them, then their after-school activities would have been nothing but threesomes. Alas…

 Now after being denied the presence of his beloved for the entire break, Hogs waited for her return with palpitations in his ghostly heart. He saw her hugging her friends as soon as she came back, longing to feel those breasts pressing against him instead. Later in the evening the fat ghost followed her back to the Gryffindor dorm, hoping to see more of the pale body he craved. 

 Headless Nick noticed him in the main hall and squinted. “Hogs, you again! I told you to leave this place at once, you filthy old pig. This is no place for you!” 

“Come now, Nick. I’m doing nothing wrong! I’m just lonely!” 

“If you are so lonely, then an appeal to the Ministry of Magic will solve the matter. Come, get the hell away and don’t come back. Leave these poor girls alone.” 

 The Gryffindor girls around the table all lifted their heads, listening. “Who are you talking to, Nick?” Lavender asked him.

“Why, this pervert over here! You still can’t see him?” They shook their heads. Nick frowned at Hogs. The fat ghost kept his hands folded over his hairy belly, trying to look innocent, though his eyes kept going over to Hermione, focusing on the way she absent-mindedly licked her lips while doing research and eating snacks.

“That’s enough! Out! Out!” called Nick. “Out before I have them come for you!” 

 Hogs made his way out as instructed, though his plans were unaffected by Nick’s unpleasant interruption. 

 He waited for nightfall, then snuck his way into the chamber where Hermione and the rest of her dormmates were hanging out and preparing for bed. 

“It’s good to be back,” said Parvati. 

 Even now, Hermione was still reading on her bed. “You’re telling me. Not having access to the school’s library can be such a pain.”

“Stop it!” cried Lavender, annoyed to hear more of her humble-bragging. “And close that book, it’s sleeping time.” 

 How very wonderful, thought Hogs. The short fat ghost stood at the center of the dorm and basked in the beauty of the young girls as they shed their uniforms and stood for several seconds in their underwear before putting on their pajamas. 

 Silky skin, lascivious curves, palpable heat… That slut Lavender did not even bother keeping her titties contained inside of a bra. Yet, his attention was all going back to Hermione as always, who quickly put on her pajamas in the same expert way she did everything else. She folded her uniform neatly, then lay in bed and wished the others good night. 

 As the lights went out, Hogs got closer to her bed - so aroused that he could feel his ghostly prick ready to burst through his pants. Though only a few moments had passed, the sleepy Hermione appeared to be asleep already, her hair spread out beautifully down from the gorgeous face bathed in moonlight. 

 Tantalized by the sight of her rising chest, he put a palm over her breasts in an attempt to cup a feel. When the hand went through, Hogs cursed under his breath. I’m fully aroused! Why isn’t this working? He could only imagine how soft those big tits had to be. Yes, nice and soft, ready to be enjoyed by his expert hands after this entire break of dreaming… 

 The more he thought about it, the more excited he got, till he could finally feel tingles of physical sensation coming to his palm. As the sleeping Hermione’s chest came up again, he pressed down, and this time could sense his fingers going into the squishy flesh. This is incredible… 

 Hogs was worried that she might wake up suddenly and make a connection about what could have been happening. Nevertheless, the ghost was too perverted to help himself, so he clambered in bed with her anyway, lying down next to her. Some parts of his body were more physically present than others; overall, though, he could close his eyes knowing he was next to his beloved Hermione, enjoying her embrace. 

 His disgusting mouth came up to her lips, giving her a few ghostly kisses that she could not feel. Then he reached down and attempted to rub at her pussy, once more being held back by his spirit form. Bloody hellfire! Why is it always so difficult? 

 It took concentration, quite a bit of it, but after picturing exactly what he wanted to do and what effect it would have, his fingers finally managed to move across her sweet young pussy. Hermione gasped lightly in her sleep and opened her mouth. 

“That’s right, my sweet darling, just enjoy my touch…” 

 The feeling in his hand came and went, but it was clear that Hermione could feel him sometimes. She shifted uncomfortably, then instinctively threw off her covers completely as her slutty body started heating up. 

 Hogs kept trying to kiss her the entire time, but half a dozen attempts still weren’t enough to get him a simple kiss. Getting his physical form to extend all the way to his mouth was proving to be a challenge.

 The Gryffindor appeared to be getting so worked up that Hogs feared she might wake up at any moment. As her mouth opened to speak, the ghost wondered what dirty word would escape her sensual, red lips. Would she be asking for her daddy? Begging to be spanked? Politely asking to be left alone?

 Instead, she whispered: “Chapter fourteen, page six…” 

 Chapter fourteen, page six? Hogs repeated, feeling indignant. Was this little minx still thinking about her studies even now? Even as he touched her! That brain must be truly something if it was this active even in her sleep. 

 The more he thought about how smart she was and how quickly her brain must have worked, the more the thought of interfering with it aroused him. Could I do such a thing? What if I ruin her somehow? The concern did not work to stop him. If anything, it only pushed him to want to do it that much more as he could feel tingles of physicality firmly seizing in his finger. 

 As she slept, Hogs brought the tip of his index against her forehead and slowly pushed it through. The strength of his finger was not entirely there, but it was enough feeling to have an effect on them both. As he inserted it deeper, he made contact with her brain and felt it pushing back. Sleeping, Hermione’s face first cringed. But as it went even further, she relaxed and let out a heavy sigh.

“That’s right…” Hogs told her. “Just take it easy, my darling. Take it easy…”

 By now, his finger was all the way inside her brain, and every movement got her to respond somewhat, either by shifting around or making a different sound with her mouth. Then, he prodded a little too far to the right, and her eyes opened wide. 

 Hermione saw the fat little man lying next to her on the bed and froze. Only a few moments ago, she was trapped in a nightmare where every single copy of a textbook missed the exact same chapter that was required to finish homework. Now she was staring at a hideous creature with warts covering his face and hair sprouting from the belly that seemed ready to burst from his shirt.

 As she attempted to move and think, she was stopped by the strange sensation that another force was acting upon her brain. She slowly began to realize that it was the ghost messing around with her, but she could not understand why or how. Ghosts aren’t supposed to be able to do this!

 Her body passed from different sensations, from feeling cold, to feeling hot, afraid, exhausted, energetic, horny, suicidal, all in a quick succession as he kept prodding around her head. 

 Hogs expected her to start screaming at any moment. This would be the end for him. He wasn’t even sure how it was that she could see him now, but he expected it had something to do with him getting horny enough to physically occupy the space. Still, he couldn't run away from this now. Instead, he figured out that his manipulations were keeping her docile, and his desire to fuck her only got that much more intense. 

 What a beautiful brain this is, thought the ghost. Smart, but oh so malleable. Even in terms of raw feeling, he was rather enjoying the tightness of her brain. He could still remember the sensation of fucking many pussies in life, though he could not remember the faces that went with them, and none of them were ever quite this hot and this tight. 

 Then the most daring idea so far came to him: Why not fuck her brain instead? 

 It could have very well backfired and damned him. But how could he resist when she was making it so easy?

 Still holding a finger down on her brain to keep her in check, he slowly rose and finally unleashed the ghostly shaft in his pants. It was not particularly long, but as thick as he was fat, with a head built like a hammer and ghastly warts sprouting all along its length. He brought it up and felt it tingle as it passed through her open mouth, but it was in the direction of her head’s interior that he was pushing. He could see it going between her eyes, till he could finally feel it making contact with the insides of her brain. 

 A cross-eyed Hermione stared dumbfounded at the cock going into her brain. What in the bloody hell is this?! The hot Gryffindor struggled to think of a way to push back against this ghost and fight him off, but nothing came to mind. Not that she had never read about this - no, it was more like she couldn't access any of the information. Every time she tried to think hard on what to do, an impulse from her brain made her numb and left her staring up at the fat man raping her again. Please…

 Hogs groaned happily as he felt his ghostly cock sliding right into her brain. It was so very welcoming. He was getting so horny that there was enough feeling in the shaft to give him the impression that he was actually inside of her skull, fucking her raw brain. As his gut hovered over her face, his eyes went down till they finally found hers and he grinned. “Thank you, Miss Granger. Your brain is so lovely.”

 The ghost thrust in deeper. Hermione shuddered and wanted to scream. He’s fucking me! He’s fucking my… my brain… The thought was so irrational that it almost couldn't be processed. A ghost fucking her skull of all things? Maybe this is all just a terrible nightmare. Yes, it has to be. I just need to close my eyes, sit still, and it will all be over soon…

 Hogs could tell that this was traumatic for the young wizard, but there was nothing he could do about that. It wasn’t her fault that she was this hot, but it wasn’t his fault either. This was just a natural thing that needed to happen. It feels too good to hold back… 

 The veiny little ghostdick went right between the two halves of her brain and got squeezed in wonderfully. It was as pleasurable as being hugged by the best tits in the world. He took it one step further and moved his fingers through her skull, getting a tentative grip on her brain. Pushing from each side as if he were titfucking her, he thrust in and out of her head like a frenzied animal as frozen Hermione convulsed, spit running from her open mouth. 

 There was no doubt now that he was getting horny. Her shivering hands managed to make their way down to her pants, which she quickly took off before she started rubbing herself. “Why, Miss Granger, you’re such a slut!” said the pleased Hogs. “I take it you’re enjoying this?” 

 Hermione’s brain was in such a sorry state that she wasn’t even entirely aware of what was happening. A part of her knew that she was experiencing pleasure and sought to maximize it by touching herself. But a completely different part still thought this was a nightmare that she needed to ignore so it could pass and bring about the next day. 

 Hogs was perfectly fine with that. The ghost fucked her brain, enjoying himself immensely, dumping his fat gut on top of her head as he relished the knowledge that his dick was the one to be ruining this prime student forever. All that knowledge in her head, all that learning, just so her amazing brain could ultimately be used as a pussy by his strong cock. 

 The fat ghost glanced back and noticed that she was really enjoying herself. Her slender fingers were practically vibrating as she rubbed her clit, while the other hand spread her young pussy wide open. He rammed his cock deep to see what would happen, and then heard her high-pitch mewls. Her quivering thighs opened wide, and the first jet of her hot juices flew into the air. 

“Wow!” he declared. “You’re really going for it!” And here he was thinking he was the pervert. I haven’t even come yet! 

 Knowing that Hermione was enjoying him so much made it that much better for Hogs, and his cock was now getting so potent that he was afraid it would get stuck inside of her head. What a thing that would be… Eager to release his load, he firmly squeezed her brain around his dick, groaning as he came along with her. 

 The ectoplasm seed shot into her head and began to swirl around her brain. It was so much that even Hermione could feel it - a heavenly sensation, as if a person had picked up her brain from her head and deposited it in some cool and refreshing bath. 

 In fact, the energies being unleashed by their fucking were so potent that apart from their own orgasms, the other girls in the dorm were affected by proxy as well. Parvati was experiencing a dream in which several students were gangraping her and pleasuring her against her will. Lavender and the other girls trembled and touched themselves in their sleep as they had their own various fantasies come to them as vivid dreams. 

 There was no way Hogs could have known at the start that his flirtatious intentions would have such drastic consequences. Hermione was melting away for him, just a shivering mess that came over and over, the bed drenched after her, while the floor in front of her bed glimmered with the pussyjuices that made their way there. 

 Though he came once, all these realizations were getting him ready to come again. The ghost fucked her brain into mush as she lay there in her bed, launching rope after rope of ectoplasm into her brain, till he could see Hermione’s eyes rolling white with pleasure in her skull. He had turned her brain into a fucktoy, and now the rest of her followed suit. Her young wet mouth opened for a cock that wasn’t coming. 

 I’ve completely ruined her, thought Hogs, with just the tiniest bit of guilt.

 He came one last time, then kept thrusting as his arousal died off and the feeling in his body went away completely. He was spent. Hermione calmed down, too, and after a while opened her eyes to see that there was nothing there. 

 It was only a nightmare, she told herself, feeling embarrassed.  She realized she had been touching herself the entire time and quickly pulled her pants back up, uncomfortably switching to her side. What was that? Her fingers moved along the side of her head, trying to feel what was going on inside. It did feel like something was moving, but that was crazy… 

 No, this was just her feeling awkward because of the nightmare. Ghosts couldn't do anything like this. She had read enough to know that…

 Perhaps the strangest thing was that Hermione noticed nothing different about herself when everyone else did, especially Hogs. The following day, the ghost went to check in on her and noticed that her robe was open, and that she no longer wore the sweater of her uniform, but only a white shirt instead, unbuttoned low enough to give an ample view of her cleavage. All the guys in her class stared, but she saw nothing wrong with it.

“Hermione…” said Ron, gulping. “Isn’t that a little too revealing?”

“Oh, stop it, Ron! Mind your own business. Can’t you see how hot it is?” Her demeanor, her voice, everything was the same. But her behavior became altered in one distinctly and highly slutty way…

 Hogs noticed that the professors did not dare say anything. Had it been anyone else, maybe they would have drawn attention to the behavior. But they all knew Hermione as the good, quiet student. There was no way she would be acting this way for the wrong reasons…

 She’s become a total fucking slut, thought Hogs. Later in the day, he followed her to the library and noticed all the books on her table were about alchemy, all opened up on love potions specifically. All except one dealing with the spirit of sexuality in the wizarding world, though that made him wonder what exactly its purpose was… 

 Harry and Ron were perturbed by the sudden shift in behavior. “Hermione,” Harry dared to say. “Are you really okay?”

“Yes, of course! Why does everyone keep asking me that?”

“You’re reading about… a love potion?” Ron grimaced as his eyes went over the ingredients required. 

 Hermione smirked and slammed the book over his hand. “You aren’t little boys anymore, Ronald. Yes, sex is real and people do it. Even wizards. I can’t believe I haven’t learned about all this stuff until now. This is seriously important!” 

 Her two friends weren’t sure about that, but there was no way to dissuade her. From Hermione’s perspective, they were the crazy ones. The experience with Hogs was so traumatic that her brain rejected it completely. However, the effect of the ghostly seed her brain was swimming in was very much clear. 

 Hogs sat down next to her in the library, feeling an odd sense of pride. Almost a father’s pride… 

 He had taken this perfect student and turned her into a slut. The smartest slut there ever was, that was still too innocent to realize how dirty her behavior and interests now were… 

 Just what are you going to do next? he wondered as she began to take comparative notes between the different love potions for her research…
