The Lust of Gryffindors

Chapter 35: Pranks and Polyjuice Parties

Harry sighed as he passed over another three hairs. "Just make sure she knows not to wander around the halls in my skin."

Hermione smirked as she accepted them. "Don't worry. I intend to keep her very busy."

"I don't doubt it."

She had successfully talked him into allowing Ginny to join her Polyjuice genderbending experiment. Hermione wanted to get another girl's perspective, and she had chosen the relatively inexperienced Ginny to go first. She intended to ask Angelina to participate later. Because the sensations were so subjective, she wanted as many different perspectives as possible, but would only use people she trusted implicitly.

Harry had begged off doing more sessions for the moment. He still considered it bizarre to get fucked by himself, and using the body of another member of the Pride wasn't any more appealing. Given Hermione's enthusiasm, however, he wondered if half the girls in the Pride would end up experiencing his body from the inside. He didn't really object. It just felt strange.

"What exactly will you be doing with her?" he asked.

"This and that."

"You're going to corrupt the hell out of her, aren't you?"

"Nonsense. She considers me her guide to the wonderful world of sex. She couldn't ask for a better one."

He rolled his eyes. "You just want to see if she gives you that wave feeling thingy like a real guy does."

She grinned. "I'm not expecting it, but let's call it a secondary benefit of the experiment."

"Oh, Merlin."

"This is for science! We won't abuse your body. Too much."

"A galleon says she doesn't start touching her new penis as fast as you did. Or cum as fast."

"No deal."

"Just be careful taking her to the Room of Requirement. Someone hexed one of our firsties last night, and I'm pretty sure it was a Slytherin. You can take my cloak if you want it."

"We'll be fine. I can handle myself."

"I know you can. You should be careful around Bulstrode though. She might be dangerous when you have patrol together."

"Why?"

"I forgot to tell you earlier, but I saw her and Parkinson hooking up on the map. If they're tight, she could be out for some revenge."

"Hooking up?" she asked incredulously.

"Yep. In the middle of the night in a Slytherin bathroom. Their feet were right on top of each other for a long time."

"Wow. I never would have guessed that. I'll be careful, but Bulstrode has never tried to mess with me."

"Maybe I'm just being paranoid, but better safe than sorry."

She patted his cheek. "Things will calm down soon. The Slytherins aren't rallying behind Nott. They're just scared of our retaliation."

"They've got a funny way of showing it."

Three days later, Hermione met Ginny and an extremely nervous-looking Colin Creevey in the alcove above the Pride. Harry had granted his permission to approach him, so long as he understood that he wasn't allowed to be a fanboy in the Pride—and that no cameras would ever be allowed inside.

Angelina okayed the decision as well, after a brief discussion with Ginny. She was less concerned that he might be gay—there had been plenty of gay members before—than that he wouldn't be able to handle being by far the smallest cock in the room. She left it in their hands, knowing that the Pride had a way of helping people grow into themselves.

Hermione had approached Fred and Lee too, as they were the ones who indulged themselves with other boys most freely. Given that they were longtime friends, she didn't want to assume that they would be inclined to do so with Colin. But they had assured her that they had no problem with an additional boy to play with, even if they mostly slept with girls.

It might not be an issue anyway. She wasn't even certain that Colin was gay. She had only Ginny's intuition to guide her.

Colin swallowed thickly and peered down at the action occurring below them. She had already explained the details of the club, while Ginny stood silently as moral support for her friend. He appeared to be enraptured by what we saw.

Hermione observed him out of the corner of her eye. This was her first time explaining how things worked to a boy, but she understood why Ginny had asked it of her. Colin certainly had a touch of the feminine about him. He was short and slight, with blonde hair and blue eyes, and there was something vaguely submissive about his mannerisms.

"What are you thinking?" Hermione asked.

"This is…amazing, but are you sure I'd be welcome here?"

"You would. But not all the guys are interested in doing things with other guys," she said, hoping she didn't offend him with her assumption. "Is that something you'd enjoy?"

He couldn't conceal a blush. "Er, yeah. I don't have much experience either way, but I like girls too. Nice ones, at least," he said, glancing at Ginny.

Ginny smiled. "Everyone is nice in here, Colin, even when you don't know them well outside."

"And you know I'm, er, not very big?" he asked Hermione. "Because I mean—"

He gestured at the room below them, where a couple large cocks were on display.

"That's okay. No one's going to make fun of you, at least not in a mean-spirited way. Everybody here gets teased about something or other, but that's because we're all here to let loose. The bigger issue is whether it will bother you."

He licked his lips nervously. "No, that's—I like seeing big ones. I know I'm small. I don't mind being teased about it. I don't know if I want to let the whole room see me though."

"You can choose who sees you. You can go to a bed and close the curtains. Or you can meet someone up here in the alcove. The whole point is to be comfortable and have fun."

"And you know I'll play with you anytime you want," Ginny said. "So would Hermione, I bet."

"I would. I like all cocks, big or small."

"You can believe her. She's the biggest whore I've ever seen."

Colin blinked at those words, but Hermione didn't bother denying it.

"She's right. We can do anything you want together. Well, if I'm not busy studying."

"Really?"

She nodded, enjoying the dumbfounded look on his face. She stepped a little closer to drive the point home. "Colin," she said softly, "I'll go to my knees right now and worship your cock. Would you like that?"

"Yes," he said faintly.

"Will you show it to me?"

As if he had been given a command, he hastily unbuckled his belt and slid down both his trousers and underwear, watching her face. His cock sprang free, already very hard.

Hermione went to her knees. She took a moment to examine him. He was indeed very small, perhaps three inches and not at all girthy, but well-formed. She gently wrapped her hand around him. It covered him completely. The tip of his swollen head throbbed against her palm. She squeezed it and he breathed out hard.

She smiled up at him. "I like it."

"I know it's tiny."

"It's not tiny, Colin. It's cute. And I'm going to make it feel really good. That's all that matters."

"Is it the smallest you've ever seen?"

She glanced uncertainly at Ginny. She didn't want to insult the boy, but he seemed far more fixated on the issue than she.

"You can say it. He likes it."

Colin nodded, captivated at seeing her fingers wrapped so firmly around him.

"Yes, it's the smallest, but you've got nothing to be ashamed of. Things come in different sizes."

"How does it compare to Harry's?" he asked.

Hermione looked into his eyes in confusion. He seemed to await her answer with eager anticipation, even though he surely knew the answer. He already understood that he wouldn't be allowed to hassle Harry here, and had rarely done so after his first year anyway. This seemed to be about something else.

"Harry's is bigger," she said carefully.

"How much bigger?"

She examined his face, feeling as if she were playing a role in one of his fantasies. She glanced at Ginny again, who grinned and shrugged. She had said he liked being teased. It sounded more like he wanted to be humiliated. But perhaps not. Perhaps this was his way of accepting the truth without shame.

"Please, I want to hear it," he whispered.

She frowned, but indulged him. "He's a lot bigger than you, Colin."

His cock pulsed in her grip, and he seemed to be holding his breath, waiting on her to say more.

When she didn't, Ginny took over. "You're tiny compared to him. Look, her hand is bigger than your little cock. I can't even see it right now."

He throbbed in her palm again, and she raised an incredulous eyebrow at Ginny. The younger girl just smirked and mouthed 'he likes it.'

Maybe this was just a harmless kink. But if he decided to join the Pride, she intended to get at the root of it. Maybe nudge it in a different direction. Harry's little joke about her becoming a sex therapist suddenly felt prophetic. For now, she decided to play along.

She released her grip on his cock and began stroking it gently with her thumb and forefinger. He wasn't quite big enough to stroke with her whole hand.

"I only need two fingers for this cute little thing, Colin," Hermione whispered seductively. "I need two hands for Harry. That's how much bigger he is."

Colin almost whimpered. She squeezed him between her fingers and tugged harder, then teased his balls with the fingertips of her other hand. They pulled taut against his body.

Ginny moved right next to him to whisper in his ear. "He stretches her out with it every night. She can barely stand it, it's so big. Compared to him, you're hung like a house elf."

"Yes, I am," he said breathlessly.

She kissed his cheek. "I bet your adorable little cock is the smallest one in the school. You can barely see it when it's soft."

Colin groaned and closed his eyes. His cock pulsed in her fingers again. Hermione wondered just how often Ginny had played this game with him. Did he demand it of her? It seemed simultaneously brave and pitiful. No wonder she had sought her out for advice.

"Harry is so much thicker than you," Ginny continued. "And he makes her cum so hard. She writhes and moans and begs for more. You want to watch him fuck her, don't you?"

"So much," he agreed, now panting.

Hermione was growing wet from this little game, but she couldn't tell if it was from the dirty talk, Colin's strange kink, or imagining the scenario Ginny just described.

"You can watch us sometime," she said, taking over from Ginny. "Harry will fill me with his big cock and pound me so hard I can't breathe. You'll be right there, playing with this little thing. I'll be so out of my mind with lust, I'll grab you and pull it into my mouth. It will feel just like this."

Without another word, she wrapped her lips around his cock and swallowed his entire length. The whole thing fit in her mouth easily, and she could suction it from all sides. She bobbed her head, sliding it along her tongue, and he gasped.

He came almost immediately down her throat. She released him and suckled gently on his crown. Surprisingly thick pulses of cum shot along her tongue. She swallowed him whole again, and remained there until he was dry.

Hermione stood and smiled. He seemed to be giddy, not able to believe what she had just done for him. She couldn't quite believe it either. It was just another of the many surreal moments in the Pride. "Did that feel good?"

"Yes. Thank you."

"You're welcome. And you know I was just telling you what you wanted to hear, right? Your cock is small, but that's okay. I guarantee you can satisfy me with it. If you want, we'll get in that bed right now and I'll prove it to you."

"So will I," added Ginny.

Colin blushed profusely. "Er, that's—I'd like that. I'm sorry—I know I'm weird. I just like hearing you talk to me like that."

"As long as you know the truth," Hermione said. "We've all got fantasies. Some of them are weird. You can indulge yours as much as you like, but there's one thing you're not allowed to do in the Pride."

"What's that?"

"Feel bad about yourself," she said firmly. "Let's go to the bed."

XXXXXXXXXXXXXXX

Harry strode down the stairs in confusion. It was nearly curfew, and Lee Jordan had just entered his dorm room to demand his presence in the Pride. There were a dozen clothed people milling about, mostly boys, plus a handful of girls. At one end of the room was a table with several big platters of pastries and tarts and donuts and muffins.

"What's going on?" he asked George.

George smirked and threw an arm around him. "Harry! Glad you could make it. You're the reason for tonight's little prank, after all."

"What?"

The grinning Weasley gestured at the trays of food. "Since you wouldn't let us retaliate against the Slytherins last week, we decided to get creative. We had a little chat with your friend Dobby in the kitchens tonight. It turns out that these delicious pastries will be served at the Slytherin table tomorrow morning."

"Oh, Merlin. You're not allowed to poison them all, George."

"Of course not! We're going to give them a gift!"

"What gift?" he asked warily, as more people streamed into the room.

Fred put an arm around his other shoulder. "We're going to improve the taste of their breakfast! Give it that extra little kick! The snakes need more protein in their diet, don't you think?"

"It's doing them a favor, really," agreed George. "A balanced diet is important, and they've been looking peaky of late."

"You mean—"

"That's right, my friend, we're going to wank all over their breakfast, and then serve it to them."

Harry couldn't stop his laughter. The twins had a truly wicked imagination. Taking a closer look at the pastries, he realized that most of them were already glazed with icing. Adding a warm layer of cum wouldn't even be noticed.

Word of the prank spread throughout the room, and soon everyone was laughing hysterically.

"Step right up and pull out your cocks, boys!" George called out. "Let's show our regards to Slytherin House!"

For the next hour, the Pride was filled with merriment as a line of boys continuously jerked off onto the trays of food. The girls helped too. Though they couldn't provide the special ingredient, they took delight in bringing the boys back to arousal and helping with the decorations. Stripes of cum that missed their targets were carefully scooped up and smeared onto the treats until they glistened with a delectable white sheen. Never had the Pride seen so much laughter—or so many handjobs—in a single night.

When their work was finished, Alicia hit every last tart with a preservation charm, so they would be warm, gooey, and fresh when morning arrived. Dobby planned to add some sugar to further conceal the true nature of the toppings.

The entire Pride exchanged congratulations on a job well done, and Harry renewed his vow never to piss off the twins. Tomorrow would bring the most highly-anticipated breakfast in a long time.

Attendance at the Gryffindor table the next morning was remarkable. More students than usual arrived early and stayed late. The Pride lined up en masse on one side of the table so they could have a clear view of the Slytherins.

Though they did their best to remain inconspicuous, even the Professors noticed that the Gryffindors were shooting frequent glances at the Slytherins and then almost doubling over in mirth. The Slytherins didn't know what to make of it, and even other Gryffindors were unnerved by the glee that was emanating from some of their housemates.

Harry sat between Hermione and George, and almost hurt himself trying to control his laughter. Every time someone bit into a pastry and wiped the messy icing from their lips, or licked it from their fingers, his face turned red and his ribs ached. No one had ever seen The-Boy-Who-Lived have a giggling fit, nor Hermione Granger coughing uncontrollably. Quite a few assumed that it was the Gryffindors who had been pranked.

He had to momentarily leave the table when Daphne Greengrass bit into a tart, raised an eyebrow, and consumed the rest of it with gusto. Tracey noticed his behavior and narrowed her eyes, but couldn't decide why the Gryffindors were acting so strangely.

Hermione took note of how many people consumed the tainted food, knowing it would be a memory worth preserving. She'd had the foresight to keep it away from where the first-years usually sat, but every single fifth-year had eaten something. Nott consumed a huge glazed pastry, and she dearly hoped that it was Harry who had decorated it. Only Pansy Parkinson grimaced at her glazed donut and set it aside. Millicent Bulstrode consumed four.

Everyone in the Pride knew they would be telling this story amongst themselves for decades. One day, Harry planned to tell Tracey and Daphne the truth, just to see the look on their faces. Preferably when they were naked and nowhere near a wand. It wasn't proper revenge for Nott's attack, but it certainly helped lighten his mood.

XXXXXXXXXXXXXXX

The atmosphere in the castle eased over the next week. When no new attacks took place, the hostilities between Gryffindor and Slytherin gradually returned to their normal levels. Parkinson continued to look resentful and give everyone a wide berth.

It helped that Halloween was approaching. Decorations appeared in the Great Hall and common rooms, and a festive atmosphere took over.

Harry desperately hoped nothing bad would happen this year. It was an unlucky day for him, even if the winter solstice loomed much more ominously. They had made no more progress tracking down Voldemort, Crouch, and Nagini. Dumbledore believed they were locked down in a safe house somewhere. The Headmaster was still hunting for clues on horcruxes and acquiring old memories from people, but it wasn't enough to satisfy Harry. He was growing sick of waiting. He wanted to force something to happen on their terms, not wait and react to a disaster.

He tried to push away his apprehension and focus on the normal routine of Hogwarts. He and Hermione were ensconced in the library most evenings, adhering to her rigorous study schedule for OWLs. His afternoons were mostly occupied with quidditch or hanging out in the common room. He was able to spend more time with Ron, Neville, and Dean now that he didn't have a deadly tournament to prepare for.

The Pride satisfied their needs almost every night. Along with Katie and Hermione, Ginny had become one of his regular lovers. Demelza had sought him out several more times as well. She told him she wanted him to be her first when she was ready, which he suspected would be very soon. She hadn't yet participated openly in the Pride, but was growing bolder by the day.

So too was Hermione, and not just in the Pride. Harry found himself dragged to the Room of Requirement at the end of the week. Hermione's experiments with Polyjuice now included Ginny, and in the second session she had begged for a threesome. Except he would be in her body, and both girls would be occupying his. He had acquiesced after much whining, and allowed them both to ravish him from behind.

Harry was willing to admit that it wasn't an awful experience, at least as an occasional break from routine, and so long as he didn't have to look at his own face. He much preferred burying his face in a pillow and losing himself in the sensations of a girl's body. Ginny had cum almost straightaway, but Hermione was becoming competent as a male lover. She no longer found it strange to have sex with her own body, and didn't hesitate to give Ginny tips and interrogate her about her sensations. He knew she already had reams of detailed notes. She was still corresponding with that witch from Brazil, who probably provided more inspiration for her 'studies.'

Once their Polyjuice wore off and they were back in their real bodies, Harry spent an hour fucking both of them senseless, reminding them that he was the expert on using his cock. Ginny had been very uncomfortable on a broom the next day, but wore a silly smile nonetheless.

He intended to get a little extra revenge on Hermione. She enjoyed being cheeky while in his form, and when the time was right, she would find herself tied to a bed and punished somehow. He just needed to think of something suitable.

XXXXXXXXXXXXXXX

Harry could hardly control his anticipation as he looked at the gathered faces. Tonight was going to be interesting. Halloween had passed without a hitch so far, but he couldn't predict how everyone would react to their planned festivities in the Pride. Spirits were still high after their prank on the Slytherins.

With his and Hermione's help, Angelina had organized a very special party, and it was finally time for it to start. On a table in front of them were more than 30 doses of Polyjuice. Every regular member had shown up, though Demelza and Colin had chosen not to participate. Cho and Leanne Turner were present, and everyone could feel the excitement in the air. The entire group was nude, and some of the boys were already hard.

"Alright, you lot," Angelina said loudly, "you know what's about to happen. You've each contributed a hair, and you'll each get a dose. Remember, this will only last an hour, so don't waste any time getting your freak on. Come up one at a time and pull a name from the hat, and don't forget to thank Harry and Hermione for their generous donation."

"Can we really not choose who we're going to be?" Jo Hampson complained. "I want to be a guy. Or Hermione."

"Nope. No gender swapping this time. If this is a hit, maybe we can do that in the spring. And it's gotta be random to be fair. Otherwise, all the boys would pick Dean, and none of the girls would be able to walk tomorrow. You all get to be one of your friends for Halloween, so just relax and enjoy it."

There was laughter and cheering at that. Dean just smiled and shrugged. Hermione looked at Hampson oddly, surprised that she would want to experience her body.

"Oh, and don't tell anyone who you're turning into," Angelina added. "You can do that afterwards. Keep it anonymous for now. Lust potion is available for whoever wants it, and I strongly recommend it. Let's get fucking kinky, people."

One by one, each of the members pulled a random name from a hat, then accepted their pre-prepared potion. They were instructed to move to a wall and face it, so they wouldn't know where anyone else was standing once the potions were imbibed.

Harry looked down at his potion. It was a dull silver. He had drawn Julian Martigan's name from the hat. That was mildly disappointing, but not overly so. They weren't close friends, but perhaps that would make this less awkward. Martigan was similar to him in build, though taller, and fairly well-hung.

"Okay, my darlings!" Angelina yelled. "On three! One, two, three!"

Harry uncapped and downed his potion, hoping it wouldn't taste too foul. He suddenly gained four inches in height and thirty pounds in weight. His shoulders felt further back than usual, and he was now a little pigeon-toed. His face felt odd, as if it were both easier to scowl and easier to smile. He ran his hands over it hesitantly. Martigan was handsome, but he'd never realized the haughty boy had such a long nose.

He turned and looked around the room. It was strangely silent. Everyone was looking down at their new bodies and moving limbs experimentally. Some were rubbing skin or fondling themselves. Almost no one had experienced Polyjuice before.

There was some awkwardness in the air as everyone got comfortable and observed their neighbors. The protocols for approaching someone seemed to have vanished, because it wasn't clear whom one was really approaching. Now he understood why Angelina had insisted on lust potion.

He marched to the table and dabbed a drop on his tongue. He shivered, and Martigan's cock instantly grew hard. He squeezed it, trying to get a feel for the differences in this body. It was smaller, and not quite as thick, but the sensations were similar and he couldn't wait to bury himself in someone.

Whoever was occupying Cho's body brushed against him and he reached out and grabbed her wrist. She looked at him with lust-filled eyes and he pulled her to the closest couch.

They were soon kissing each other ravenously. He reached between her legs to tease her just as she lowered her face to his cock. Harry wasn't sure how it happened, but they somehow maneuvered themselves until they were lying side-by-side in a sixty-nine position. Cho—or whoever was occupying her body—raised her leg and he eagerly pressed his face between her folds. She held him in place with her thighs, nearly squashing his head, and pulled his cock into her mouth.

He groaned as he slid down her throat. The girl was so enflamed with desire that she didn't attempt to tease him. She simply opened wide and swallowed his cock whole. He thanked Merlin for Martigan's smaller dimensions as her throat squeezed him. The real Cho couldn't have pulled off such a move with him.

She kneaded his balls painfully, reminding him that he was supposed to be pleasuring her, but the pressure surrounding his cock was almost too exquisite to focus. Not bothering to be gentle, he slipped three fingers past her dark lips and into her heat. She was musky and soaking wet already. The girl squirmed as he stroked her g-spot and suckled her clit without mercy.

The pair pleasured each other hungrily, lost in the sensation of being in other bodies. She released his cock only when she needed to breathe. He thumbed her clit and nipped at her labia with his teeth, but she didn't seem to mind.

When she paused again to breathe, he couldn't resist thrusting his hips. The girl held still and let him fuck her face. Harry was amazed that she could take everything, and didn't hesitate to take advantage of the situation. She gagged once or twice, but held obligingly onto his balls to pull him forward with each thrust.

With both partners beside themselves with lust, it didn't take long for either to reach the moment they sought. Harry drove into her face, not bothering to warn her before he stiffened and exploded down her throat. She wrapped her lips around his base as thick stripes of cum burst from deep within him. The sensation was so wonderful that dark spots crept into his vision and he had to remember to breathe.

She removed his cock from her throat and gasped for air. Harry renewed his efforts to drive her wild. His fingers curled and his thumb twisted and his tongue swirled, and the new Cho soon followed him into ecstasy. She whimpered as her pussy flexed around his fingers and soaked his nose with her wetness. He breathed in deeply of her scent as she came down.

When she finally groaned and removed her thigh from his head, he sat up and looked around. The room had already descended into the most delightful kind of chaos.

Hermione held her breasts in wonder. They were so firm and so full, and her nipples so sensitive, she could happily squeeze them all night. No wonder Lavender liked showing them off so much.

She had gotten lucky, she supposed. Lavender was arguably the most beautiful girl in the room, and her breasts were magnificent. She squeezed them for another ten seconds before focusing elsewhere on her body. She had gained three inches in height and probably twenty pounds. Her hips had widened and her flesh felt a little softer. She tentatively brushed a finger across Lavender's clit. The sensation was almost exactly what she felt from hers.

She looked around the room. Everyone was milling around in confusion, both adjusting to their new bodies and uncertain how to proposition a stranger in a familiar body. Her eyes fell on Dean. The boy in his body was standing still and stroking his monstrous new cock in awe. It was already rock hard.

It suddenly occurred to her that Lavender's body could handle Dean's entire length. He regularly pounded her until she was moaning loud enough to be heard in Hogsmeade. Her nipples grew achingly hard and she felt her new pussy expand and soak. Fuck the lust potion. That could wait. She was going to commandeer Dean's cock before anyone else got the chance.

XXXXXXXXXXXXXXX

"Ten minutes left!" Pippa Pemberton yelled commandingly. Harry could only assume it was Angelina occupying her body.

Martigan's body was sweating as he drove himself deep inside Ginny's soaked pussy. Her legs were pushed behind her shoulders as Harry pounded her as hard as he could, driving her into the cushions of the seat. She too was sweating and moaning, wearing an expression he had never seen on her face. He could pound her more easily in Martigan's body than his own. It helped that she was so wet, spreading little droplets of arousal everywhere when he thrust. He loved it when Ginny lost control of her body, even when it wasn't really her.

The girl beneath him cried out in ecstasy and spasmed around his cock, soaking him even more thoroughly. He drove into her harder and seconds later orgasm overwhelmed him too. He groaned as he spurted deep inside her. Martigan's orgasm was equally intense, no doubt spurred on by the lust potion, but he could tell distinct differences. He produced less cum, and it felt as if his balls hadn't drawn closer to his body. It didn't matter. Only filling the moaning girl beneath him mattered right now.

He pulled away from her panting, and instantly Molly Beckwith—or whoever was in her body—grabbed him by the shoulders and pulled him to the ground. She spread her legs and looked at him with desperate eyes.

"Finish me," she begged. "Please."

Her pussy glistened with cum, but he buried his face in it and tongued her swollen lips eagerly. He pulled her clit into his mouth and she whimpered, sounding almost in pain, but didn't ask him to stop. He drove three fingers into her and stroked her walls, trying to get her off quickly. The lust pouring off her spurred his own arousal, and his cock started to grow hard again.

It took Molly less than a minute to start whimpering. Her pussy contracted around his fingers and she squeezed her huge breasts roughly, kneading them into her body. She was too out of it afterwards to even thank him. She just stared at the ceiling with a glassy-eyed smile as he stood and looked around the room.

With less than ten minutes before their potions wore off, people were coupling in a frenzy. The room was filled with moans and groans and shrieks and the sounds of slapping flesh.

It could not have been more different than the first five minutes of the evening. That had been awkward and hesitant. At first, people had sought out their regular lovers on instinct, even though someone else was wearing their body. But then the lust potion had kicked in, and everyone ceased caring about who their partners were. The goal was to engage in as much debauchery as possible in under an hour.

His eyes met Katie Bell's. Or whoever impersonated her right now. She was free, having just risen from a couch after a session with the faux Lee Jordan. She was breathing hard, and her breasts and belly were streaked in cum. He grew hard again just looking at her. They probably didn't have much time left. Should he just wait until he was in his own body? He would be more comfortable that way.

The lust potion howled from deep within him, and he saw the same feral look in her eyes. Fuck it, they couldn't wait. If he changed back into himself while he was buried inside her, so be it.

Harry was on top of her seconds later. Katie wrapped her arms and legs around him as he parted her warm depths with his cock.

"Fuck yes, Julian," she murmured.

He didn't bother to correct her. He was too lost in the way her body clung so tightly to his. He adjusted his angle of entry, knowing how to please Katie's body even when it wasn't her. When he slid along her g-spot, she squirmed and pulled him even closer.

He was still minutes away from release when his body transformed. The strangest sensation flowed through him. His body shrank while his cock grew. The girl beneath him moaned as he suddenly filled her more thoroughly.

Seconds later, she shuddered and turned into Alicia Spinnet.

They paused and stared into each other's eyes. Both were overcome with vertigo, and wondered if that meant they should stop. Their bodies decided for them. Harry slid slowly into her once more, and her pussy renewed its tight grip on him.

"That's it, Harry. Give it to me nice and slow," Alicia whispered, and pulled his mouth into a lusty kiss.

XXXXXXXXXXXXXXX

Hermione drove herself onto Dean's cock with reckless abandon, slamming her ass against his thighs. She was so wet that he was able to slide along her walls almost violently, burying every inch of him inside her. She'd never been so wonderfully stretched. It felt as if his cock might burst out of her stomach, but even the pain was pleasurable.

She rubbed herself and panted as the boy beneath her began meeting her thrusts with his own. This was the second time she'd sought out Dean's body tonight. The hour was approaching its end, and she'd wanted to feel him stretch her one last time.

Dear Merlin, his cock was magnificent. But even inside Lavender, it was too big for such rough sex. She would definitely be feeling this tomorrow. It would be worth it. Her pussy felt so engorged with need that there weren't enough cocks in the world to satisfy it.

She couldn't help moaning as she bounced on him. Lavender's body was a sexual machine. It had cum eight times in less than an hour, and another orgasm was approaching quickly. If only her time didn't run out. The boy suddenly stopped pounding her and pulled her body against his. He groaned and spilled himself inside her in thick bursts.

His release didn't spur that wave of ecstasy she felt in her own body—a curious fact that she filed away for further study—but it was enough to push Lavender's over the edge. Her cunt flooded with new wetness and she gripped and released Dean's cock in spasms of bliss. It was so intense she could feel the contractions deep in her ass, as if it were trying to turn itself inside out.

She collapsed against his chest, totally spent. The lust potion still flowed through her veins, but she needed a moment to recover before she could even think about satisfying its cravings. Lavender's body didn't beg for more as insatiably as her own did.

Suddenly her head swam and it felt as if she were shrinking. Her body reverted to normal, and Hermione found herself laying against the chest of Neville Longbottom, who had the biggest smile on his face she had ever seen.

He made to sit up but she pushed him back into the seat and started grinding her hips into him. His softening cock was still trapped inside her. It felt good to be back in her own body, and that familiar ache was already calling out for satisfaction again.

"Don't move, Neville. You'll be hard again soon enough."

"Oh, my God, that feels so good," Hermione moaned. "I love your cock so much, Harry."

"And I love where it's buried right now, you dirty girl," he said with a satisfied smile.

She was riding him slowly, keeping him imprisoned inside her while she rubbed her clit against his pubic bone. He squeezed her breasts from below, kneading them as if they were his most prized possessions. When he held her nipples between his fingers and pulled on them, she made the most delightful noise.

The Polyjuice had worn off more than an hour ago, but the lust potion was still affecting everyone present. People were paired off with their closest friends and regular lovers, sating themselves and comparing notes on their new experiences. Loud moans and the smells of sex filled the room, plus the occasional bout of laughter as someone revealed an awkward moment from the night.

The party had been a huge success. It was bound to be, with lust potion involved, but it was the anonymity of the event, and the experience of not being oneself, that had removed all inhibitions.

He had slept with seven or eight girls in the space of that single hour, plus pleasured several more during his brief periods of rest. He couldn't even recall everything. He remembered Ginny, Cho, and Hermione for certain, and Angelina and Pippa had manhandled him at the same time. Everyone in the room had given themselves over to lust and rutted like animals in heat, uncaring who it was with.

It felt good to be back in his own body. The experience had been amazing, but he didn't want to do it often. He knew his own body intimately, and how to control it. Like he was doing right now with Hermione.

Her eyes were closed and her mouth open as she rolled his cock around inside her, lost in the sensation of him filling her. She was hot and slick, and he was so hyper-aware of his cock right now that he could feel every inch sliding through her soft flesh.

He squeezed her breasts hard and she squeezed him right back with her walls.

"I want to feel you cum again," she breathed. "Please."

"I'm almost there. Ride me harder."

She obeyed, lifting her thighs and then dropping her weight to envelop his cock. It took less than a minute for her to overpower him.

He groaned and bucked his hips, releasing huge bursts of cum directly into the deepest part of her. She squirmed and made one of those little noises that he associated with her losing her mind. Her pussy contracted around him and her face grimaced as they both panted in time together.

She collapsed against his chest, sweaty and exhausted. He took a deep breath and hugged her, delighted with having so much of her skin in contact with his.

"Fuck this potion," she moaned. "My body wants more, but I'm tired."

"Just lay here with me. If you need more, you can ride me again later."

He felt her nod against him. "Who was in your body earlier?" she asked.

"McLaggen. He told me afterwards. I saw him cum all over Angelina's face. Or whoever Angelina was at the time. I mean, whoever had Angelina's body. Merlin."

She giggled. "So little of that should make sense, and yet it does."

"Welcome to the wonderful world of magic. Who had your body?"

"Cho. She was ecstatic. Apparently, I cum really fast compared to her."

"I knew I could sense something familiar about whoever had your body. It was the squeaky sounds she made, I think."

"I couldn't tell who was who at all. I stopped trying. McLaggen came really fast in your body, in case you wanted to know."

"I definitely didn't. I figured out that Angelina was Pippa—wait, I got that backwards. I mean Angelina had Pippa's body, and Katie had Parvati's. Their mannerisms are the same no matter what they look like."

"Who had Alicia's body? She tried to smother me with her pussy."

He laughed. "No idea."

"Did you enjoy being Martigan?"

"Yeah. It was different, but I could pound a couple of the girls harder than I can in my own body. I'd still rather be me. How did you like Lavender?"

"Loved it," she said, unconsciously grinding her hips against him. "She can take all of Dean, and, Merlin, her boobs."

"Nice?"

"Now I know why she's always playing with them."

"You going to drag her into your little experiment next?"

"Not enough potion left, or I probably would."

He hugged her tighter. "You little slut. Aren't you glad I told you about the Pride?"

"If you had kept this a secret from me, I never would have forgiven you."

He just smiled, remembering the anxiety he'd wrestled with last year at the prospect of telling her.

Author's Note: Hope you enjoyed the twins' prank. I don't think I'm spoiling too much when I reveal that the Pride will have a genderswap Polyjuice party later in the spring. That one will be crazy. Colin will be the last new member. If you're waiting for more Tracey and Daphne, be patient.

Next chapter, Harry has a proposition for Dumbledore (no, not that kind), Gryffindor has a match against Hufflepuff, and Hermione is delighted at who shows up to the after-party.
