Harry eyed the small crystal vial of nearly fluorescent pink potion suspiciously, "What do you think it is?"
"Hell if I know," Ron muttered, reading the letter from Fred and George again, his brow furrowed in thought.
The best friends were in their usual bedtime pajama pants and undershirts, sitting cross legged and facing each other on the wide mattress of Harry's four poster bed. Its curtains were tightly drawn, and inside it felt like a snug tent. A small ball of magic light hung above their heads, and a silencing charm let them speak normally while the rest of the dormitory slept.
Abruptly Ron looked up and a broad, stupid grin spread across his face, "But I bet it'll be excellent. I mean, if those two sent me a mystery potion, sure, I'd worry my cock'd fall off. But," he turned back to the letter and read, "A prototype sample of perhaps our greatest invention yet'? For their secret partner'? This shit'll be grand, Harry."
"But why'd they put," Harry snatched the letter back from Ron, "`P.s. The potion is only enough for one, but for the full experience be sure to have a trustworthy, penis-having friend with you'? Isn't that a bit weird?"
Ron snorted, "Harry, who d'ya think we're talking about? Fred and George, a bit weird? You don't say!"
"You know what I meant," Harry grinned despite himself, gently flicking his shaggy brown hair out of his emerald green eyes, "Even for them, it's a strange way to put it."
"Eh, they probably just thought penis-having sounded funny. Or more like they thought Hermione shouldn't see it yet! She'd tell you how unsafe it is and all that bollocks."
"I reckon that makes sense," Harry murmured, his grin slowly matching Ron's at such foolproof logic. Harry uncorked the vial, "Well, bottoms up I s'pose."
He threw it back, a vinegar, metallic flavor assaulting his tongue, but as Harry swallowed there was an almost caramel aftertaste on his breath.
"You feelin anything?" Ron asked, watching Harry like he may grow horns.
Harry swallowed and rubbed his throat, suddenly queasy, "Well, I can tell it's doing something but--" Harry gasped and bent over with a suppressed cry of pain.
Ron's face went white, "Harry! What's wrong, are you--"
"My balls!" Harry choked out. He fell back against his pillows and desperately kicked off his pjs and Dudley's old, oversized boxers, his hands clutching between his thin hairy legs. Harry wheezed, "It's like somebody's stepping on them."
"Well don't hold em in a bloody death grip then!" Ron said, panicking.
With a force of will Harry put his arms to his sides, and they both stared down at Harry's crotch. His soft, uncut cock lay lifeless on thick black pubes, while Harry's balls kept rising and falling in his sack. Suddenly his balls pulled all the way up towards his pelvis, and with an audible pop they disappeared inside. Harry's voice cracked on a scream.
But then the pain suddenly and completely disappeared. Harry gasped, sweat making his undershirt cling to his skinny torso as he basked in relief from the pain. Then his hands reached down and clutched his empty sack.
"Where've my fuckin balls gone, Ron?! I--" Harry choked on his words as his ballsack slid out of his fingers and drew tight against his crotch, folding in on itself. Before Harry could process that new development he felt a gentle warmth spreading from the base of his dick, which began to shrink.
"WHAT THE FUCK RON! You said they'd only send YOU a potion that'd make your cock fall off!"
"Well, i-it's not fallen off has it? It's just," Ron gulped, looking like he swallowed a live frog as he watched Harry's dick shrink away, "Smaller."
But then Ron's eyes strayed a little lower, "Wait, Harry, your taint!"
Harry's hand gripped between his legs. It was like his scrotum was stretching to cover half his taint, and beneath it there was a mounting pressure building inside him. Harry gently massaged himself and involuntarily moaned. It felt very strange but also very good, like a feather tickling his asshole. Harry massaged harder and his crotch felt better, it felt almost as good as stroking his dick, so good Harry didn't notice his dick had stopped shrinking once it reached the size of a thimble nestled between the mounds of his empty ballsack. He just pressed harder and suddenly thin, slick liquid exploded onto Harry's hand and Ron's awed face as a vagina magically bloomed between Harry's legs.
Ron's shocked expression slowly morphed back into a grin, "Harry--you've got a pussy!"
Harry spread his legs, "Merlin's pubes, I do!"
Harry's hands began exploring his new genitals, rubbing his mound and fingering the lips of his labia, gently but eagerly searching lower, pushing inside as his fingers grew wetter and wetter. A shiver of pleasure suddenly coursed through Harry and his thighs shut his opening tight around his knuckles as he moaned, "That's brilliant."
"Well don't hide it away mate," Ron said, petulant. Harry laughed and spread his legs, making a v sign to spread his pussy.
"How's it look Ron?"
As Ron looked full on at Harry's vag he lost his tongue and blushed, "It's uh...nice."
Harry began fingering himself again, "It feels fantastic, that's for sure."
"Can I touch it?" Ron squeaked.
"Well don't be weird about it, mate," Harry grinned but scooted his cunt closer to Ron.
Ron touched Harry's pussy like an ape touching a spaceship. His thumb brushed against the clit, and Harry bit back a moan as his legs shivered. Ron's face broke back into a big, dumb grin, "Bloody brilliant is right."
They played with Harry's pussy together, their fingers studying every crease of Harry's new crotch, pressing deeper and deeper inside him, making him cum again and again, every time ready for more.
After Harry's third orgasm Ron asked, "Can I lick it?"
"Please," Harry said, grabbing Ron by the sides of his head and pulling his face between his legs. Ron didn't need the encouragement and dug in, his chin knocking on Harry's asshole as he buried his tongue in Harry's cunt. It wasn't long before his vagina was clutching Ron's tongue like a vice and squirting in Ron's mouth and on Ron's face.
Ron chuckled self satisfied, but after he kissed Harry's quivering, dripping clit he didn't let Harry's legs pull him back in.
"Hey, how come you're the only one getting head! I think it's time you get sucking, Harry, " Ron grinned and gestured to the large boner tenting his tartan pjs as he kept petting Harry's pussy.
Without thinking Harry grabbed Ron's dick and stroked it, thinking about how good it would feel in his new hole, "Just put it inside me."
"Nah, no way. Fair's only fair mate, I ate you out like a champ, I deserve some mouth action myself."
"You like pussy, Ron. I don't want to eat a dick."
"You're still a dude Harry, and that clit is still a dick."
"Whaddya mean that's a dick, that's clearly a clit," Harry said, pinching the tiny dick clit between his fingers
"Well Bill told me what pussy tastes like, and your pussy doesn't taste like that, it tastes like a knob."
"Oh, so you know what a knob tastes like, is that it?"
"Get off it Harry, like you've never cast an extendo charm before. And you're not leaking pussy juice," Ron wiped a finger along Harry's slit and held his glistening, webbed fingers up to the blue magic light, "This is just precum. And when you came jizz leaked out your clit, clits don't jizz."
Harry rubbed the top of his pussy and then sucked his finger clean. Ron was right. This didn't taste anything like Cho's pussy (which Harry had not cared for), it was just the taste of Harry's cum, maybe a little thinner than usual. And as he looked at Ron's face Harry realized it looked like he'd had multiple facials.
Harry bit his lip, trying not to laugh at his friend, "Alright, so? I didn't see you complaining."
Ron grinned like Harry had walked into his trap, "That's exactly my point--if it's not so bad," Ron lowered his pjs and his big uncut dick burst from a fiery red bush, "My turn."
Harry laughed, and to his surprise the idea of tasting and sucking on Ron's big dick actually was kinda appealing.
"Well, fair's fair I guess." Harry said. Harry leaned over to take Ron's dick in his mouth, but Ron stopped him.
"Sit on my face, Harry. No offense but I'd rather look at a twat than a bloke," Ron joked, smacking Harry's butt and laying flat on the bed, his dick pointing up to the quilted canopy like a tentpole.
"Piss off," Harry laughed, and he sat his ass right on Ron's face. Ron just took it in stride as his tongue immediately went in search of Harry's vagina. Then he pushed Harry down, sending Harry face to face with Ron's cock.
Harry took it in hand, stroking it with both hands as he grinded his groin on Ron's face. He licked the tip, and the taste of Ron's pre made Harry's tongue tingle with pleasure. He took the head in his mouth and sucked. Ron moaned beneath him and shot another spray of pre. It tasted better than fire whiskey, so good Harry realized there must have been more to that potion than his new pussy.
He pushed further down on Ron's dick. Harry's throat opened without protest, and he took Ron down to the root. Harry was rewarded by feeling Ron's tongue shake in his cunt like he was having a seizure. He sucked Ron from base to tip, his tongue twisting the whole way like he was sucking a lollipop. But it tasted better than any lollipop.
Ron's tongue pressed deeper inside Harry, so deep Ron's nose pressed against Harry's asshole. And to Ron's surprise, Harry's ass was leaking precum too. The thin, pink slit seemed to wink an invitation, and Ron pushed his nose inside the slick, unyielding sphincter as his tongue began lapping at Harry's cunt like a dog.
Harry felt Ron's dick pulse in his throat when suddenly Ron pushed Harry off. Ron grabbed his wand and pointed it at his prick, "Ejacunotus!"
Ron's dick bounced in protest, spraying a rope of pre across Harry's sheets, but his climax was halted. Ron wiped sweat from his forehead, "Bloody hell, Harry. I can't waste my load in your belly."
Harry licked his lips, savoring Ron's pre, but Harry also felt how wet he was between his own legs, his pussy almost quivering with anticipation of being stretched and impaled by Ron's thick, curved cock like his throat had been. Although it was also intimidating.
Harry took off his undershirt and laid back on his pillow. Then he spread his legs, "Be gentle, Ron."
Harry's sudden vulnerability shocked Ron out of his haze of half mad horniness. Almost embarrassed he stripped naked too, and knelt between Harry's legs. He felt more comfortable once Harry took his dick in both hands and rubbed it against his pussy lips.
Ron pushed Harry's knees apart with his thighs and slowly pressed his dick against Harry's hole. At the first resistance Ron paused, but then Harry pulled his pussy onto Ron's cock himself. They both moaned as Harry's tight cunt gripped the large helmet head of Ron's cock in a soft, squeezing vice.
They started slow, Ron giving Harry an opportunity to adjust to every inch of Ron's long cock. They watched as it visibly stretched beneath Harry's skinny mound, felt as Harry's pussy began gripping and milking Ron's shaft in time with his gentle thrusts.
Then Harry had enough gentle. He wrapped his legs around Ron's waist and pulled his best friend balls deep inside his new pussy. Then they really fucked.
Ron plundered Harry's hole from every angle and every position. They fucked fast, Ron clapping Harry's cheeks doggystyle like he was running a hundred yard dash. When Harry fell on his face in ecstasy Ron fucked him slow but hard, each thrust pounding all of the keeper's weight into Harry's hole, like he would fuck him through the bed. Harry rode Ron's pole like a merry go round, squirting pre and jizz everywhere with seemingly inexhaustible orgasms.
When they finally made it back to missionary their eyes met. Harry and Ron began passionately snogging as their hips sensuously moved together in sync. Neither noticed the sudden slits of firelight that sliced down the edges of the drawn curtains, or the amazed eyes peering in on the brightly lit scene.
"Harry I-I need to cum," Ron groaned, unpausing in his thrusts.
Harry, having cum at least half a dozen times since Ron popped his cherry, had totally forgotten Ron's climax charm. He squeezed Ron's dick with his newly discovered interior muscles and laughed, "Whenever you want mate."
"Where?" Ron moaned, like a man lost in the desert asking for the nearest well.
"Wherever you want mate," Harry whispered. Ron looked at Harry like he could die.
"E-jaculo!" Ron grunted, and with a deep thrust collapsed into Harry and unloaded rope after rope of cum, each pump hitting Harry's insides like a shot of ecstasy. Harry came again, his pussy quivered and pulsed around Ron's cumming cock, and Harry's dick clit squirted another load between them.
Ron's dick slipped out with a gush of cum, and he whispered dreamily in Harry's ear, "That was..." Then he was snoring.
Harry had no sooner pushed his passed out buddy off him then suddenly the curtains surrounding them were magically thrust aside.
Harry's Gryffindor dorm mates, Dean, Seamus, and Neville, stood around Harry's bed. Dean's mouth hung open, Seamus was grinning, while Neville looked ready to piss himself. All three had tents in their pants.
"Hell's bells Potter, you have yourself a minge!" Seamus roared with laughter, pointing between Harry's legs.
"When'd you get a pussy, Harry?" Dean asked with earnest curiosity.
Harry started to answer, but Neville quickly piped up, "We can't hear you, Harry!"
Flustered, Harry grabbed his wand and removed the silencing charm. But that raised the question, "Wait, how'd you guys know I wasn't asleep?"
"The bed was shaking," Neville responded, embarrassed, "We could hear it tapping the floor."
"Weasley mighta brought the whole tower down the way he was banging that cunt," Seamus added.
Harry blushed, till Dean saved him from having to respond, "But Harry, I've seen your penis mate. How'd you get a pussy?"
Harry told them the whole story, crossing his legs but otherwise oblivious to his continued nudity. Ron kept snoring.
"Those genius fuckers," Seamus laughed, "They're gonna be richer than the Malfoys soon."
"Can I look at it?" Dean asked, and at the excitement in his kind, dark eyes Harry's legs swung open. Dean's bright smile made Harry wet.
Seamus and Neville crowded in. Seamus joked, "Somebody call a house elf, they forgot to clean up a cream pie."
Harry laughed, then pointed his wand at his pussy and said, "Tergeo," wiping Ron's cum off the surface of his cunt, although Harry could still feel Ron's seed soaking deeper inside him.
Harry let the guys look at and then touch his pussy, and it wasn't long before three guys playing with him at once made Harry cum again.
"You know Harry," Dean said, trying to sound reasonable as precum leaked through the fabric of his pjs, "If I had a pussy for the night, I'd let all my mates hit it."
"Couldn't `ave said it better meself," Seamus agreed, slapping Dean on the back and rubbing a boner half visible through the fly of his strained boxers, "I'd let you fine fuckers ride me like the Hogwarts Express."
"And I mean, if you enjoyed it with Ron..." Neville added hesitantly, his knees tucked together and torso bent forward doing nothing to hide the largest pole of all three of the boys.
Harry felt his dick clit surge. He grinned, "Who's first?"
Seamus called it.
"But if we're cucking Ronald best do it on his bed," Seamus said with a wink as he began stripping.
Harry gave unconscious Ron a gentle pat on the cheek then went over to Ron's empty four poster and laid on its edge, pulling his knees up to his chest and putting his pussy on display.
Seamus licked his fingers and massaged it, searching out Harry's hole. When he found it Harry moaned and Seamus laughed, "You ever hear of trimming mate? It's Harry Potter's hairy pussy down there."
"Pft," Hairy scoffed, biting his lip to hold back another moan as Seamus slapped his dick against Harry's wet clit and pussy lips, "Seamus Finnegan, more like...shave much, Irishman?"
"Weak sauce, Harry," Seamus chuckled, and then pushed his dick inside.
Seamus was a good bit smaller than Ron, but he made up for his size with enthusiasm. He rubbed Harry's clit, whistling as he felt Harry squirt. He started off gently enough, but when Harry said, "That all you got Finnegan?" Seamus quickly sped up to fucking Harry like a jackrabbit, and Harry's pussy almost seemed to buzz beneath the savage assault.
After a few minutes there was a loud smack to Seamus' ass and he stopped mid thrust.
"Tapping you out, mate," Dean said to Seamus, and Harry's eyes went wide as he saw Dean's dark body was now naked, his large boner proudly on display.
Dean was bigger than Ron or Seamus, but after getting fucked twice Harry adjusted easily enough, and he loved watching his tight pink pussy stretching around Dean's big black cock.
"Fuck," Dean said, falling into a comfortable rhythm as his thighs clapped Harry's cheeks, "That feels better than Ginny."
"Lucky Ron didn't hear that, he'd jinx your balls off," Seamus laughed.
Under normal circumstances, Harry might have been just as angry as Ron. He had a very secret but huge crush on Ginny after all. But impaled on Dean's long, thick pole Harry was more jealous of Ginny getting Dean's dick than Dean getting Ginny's pussy. In fact, Harry could hardly think of Ginny at all, his mind was too full of the hot boys and thick cocks surrounding him.
Dean rammed Harry with steady, sensual thrusts, and it wasn't long before Harry's pussy was seizing and squirting. Dean pulled out with a grin, admiring Harry's gaping pussy before turning to Neville, "You're up Longbottom."
Neville nearly jumped out of his skin as Seamus smacked his naked ass, but he still approached Harry's pussy.
"Bloody hell, Neville, how big is it?" Harry asked, his eyes wide at Neville's massive dong, so heavy it hung low even fully hard.
"What? I-is it too big, Harry? Should I cast a shrinking charm?" Neville asked, frantic.
"God no!" Harry said, and he pushed Neville onto the bed and straddled his huge dick, wincing and leaking as he forced his pussy hole onto Neville's meat.
Dean and Seamus masturbated as they watched Harry ride Neville like a bull. When Harry fell onto Neville's chest wracked by another orgasm, the boys nearly came at the sight of Harry's pussy stretched to the limit around Neville's prick. But Dean also noticed that the dark hair around Harry's asshole was damp. Instinctively he touched a finger to Harry's ass, and his long, thin finger slid right in.
"Christ!" Harry gasped. The sudden intrusion felt nearly as good as Neville's dick in his pussy. Harry arched his back, putting his asshole on clear display even as he kept riding Neville, "Please fuck my ass Dean, I need it mate, that felt so good."
Dean didn't need to be asked twice. Harry saw stars when Dean's dick first knocked on his ass, although it must've made his pussy do something crazy because it made Neville moan. By the third thrust Dean was fully inside and soon enough he was slowly fucking Harry in time with Neville.
"Oh jeez, Dean, I can feel your dick inside him, that's so freaky," Neville said, looking past Harry to Dean like they just had a sex doll between them.
"Freaky sexy you mean. And fuck, his ass is squeezing me near as good as his pussy was," Dean grunted between thrusts.
For Harry it felt like he was being ripped in two. But at the same time, it was the most magical, sublime pleasure he'd ever experienced. He needed to be stretched, to be filled, to--
"And where does that leave me, ya wankers?" Seamus said, throwing up his hands.
Harry licked his lips as he looked at Seamus's thick, six inch cock, the foreskin so long it totally enclosed his dick even fully hard. His dick was moist with Harry's pussy pre and Seamus' own.
Between grunts and moans Harry said, "Grab my Firebolt."
"And what? Shove it up my ass?" Seamus asked, confused.
"Get on it," Harry gasped as Neville tickled his dick clit, "And fuck my face."
"You're a god damn genius, Harry Potter, this is why McGonagall made you quidditch Captain," Seamus tapped his head and winked as he grabbed Harry's most prized possession.
Seamus wasn't much of a flyer, but with his dick guiding him it was like he'd had a whole bottle of liquid luck. Seamus hopped on the broom sidesaddle, and flew it just in front of Harry's face.
"Thanks for the view of your ass, ass," Neville said below, which made the rest of them laugh.
Then Dean took Harry's thick hair in his fist and thrust deep in his ass. When Harry moaned Dean pushed Harry's open mouth onto Seamus' dick.
Not that Harry minded. Seamus' dick tasted just as incredible as Ron's had. He explored Seamus' snout, the pooled precum hitting Harry's tongue with the fizz of cotton candy. Harry started sucking Seamus, taking his dick down his throat as if he'd never had a gag reflex.
"Holy shit," Seamus cried out, "His mouths in fuckin credible. I don't know how long I can hold out gents, he's sucking better than a vampire."
Dean and Neville didn't need to speak. It was like each of Harry's holes was milking all three of them in sync, building them up till their dicks were twitching in time to Harry's heartbeat. And finally, with the gentlest squeeze, he made them all shoot at once.
The pure ecstasy of that simultaneous release nearly broke Harry's mind. His friends' hot cum filled him like a drug. Harry collapsed, which made Seamus tumble onto Dean who fell onto Harry who had already smothered Neville.
Ron bolted up in Harry's bed and said deliriously, "I'm awake! W-we were trading chocolate frogs I--" then Ron actually woke up with a blink. He grinned as he saw the tangle of bodies across the room, "I get two minutes of shut eye and you wankers have a party without me? Wait, why are you in my bed?"
"You were taking all of mine," Harry grunted as Seamus' ass smooshed his face while Dean's knee accidentally stabbed into his side.
"You still got a pussy, Harry?" Ron asked.
"He does!" Neville called out, squirming as Harry's pussy milked his very sensitive post-cum dick.
Seamus and Deane finally disentangled and stood on the side of the bed, while Harry slid off Neville's dick to lay dazed at his side. Neville was snoring in seconds.
"Excellent," Ron grinned, rubbing his boner, "You ready for another round?"
Seamus pointed his wand at his own spent dick and commanded, "Rennervate!" And it jumped back to a full boner, "I sure am," Seamus grinned.
"Gimme a second to catch my breath and I'll be down," Dean laughed, "Think those holes can take another pounding, Harry?"
Harry tasted Seamus' delicious cum on his lips, and Dean and Neville and Ron's a dull pleasure and warmth inside him. His holes ached from being used and stretched and for more.
Harry's thumb rubbed against his dick clit and he shivered, "Hell yes."
