Chapter 3

As the door opened Harry's jaw dropped and his brain shut down. He couldn't comprehend what he was seeing. It looked like two giant tits just sitting on one of the beds. Harry didn't even notice that the tits were waving at him.

"I think you... broke him." A familiar voice called out between quick gasps.

That snapped Harry to reality and he began to notice that his jeans were beginning to feel painfully tight. He also noticed that Ginny was on the bed, pinned to place by the two breasts the size of beanbag chairs. She was totally naked and he could see a fine forest of red hair around her pussy, matted and shining with her juices. A wand ad been inserted into her young cunt, She was flushed and breathing raggedly. Harry could see why, the wand was gently vibrating.

His body had already responded and now Harry felt like his jeans were about to explode from the pressure coming from within. Harry heard a voice in his head, it was saying 'You can't do this. It's Ron's sister.' But he only had to look at the size of those breasts, like every teenage boys wet dream come into reality. Suddenly Harry found that voice silenced under those mountains of flesh.

Ginny meanwhile had a few protests of her own. Her face was bright red and it was only the fact she was pinned down that stopped her trying to hide.
"Hermione, what's he doing here? Get him out please." She sounded insincere and breathless. The wand in her cunt was still vibrating away and she was obviously very horny. Harry could see a went patch spreading slowly, but surely, across the bed sheets.

Harry couldn't take it anymore, He felt like his cock was in a vice. He frantically pulled his robes over his head and began to yank at the button of his jeans. Hermione's hands grabbed his own and stopped him.

Hermione had stripped. Her robes were piled on the floor. She had done it without Harry noticing, but he had been a little distracted. Her pussy juices were running down her leg at the very thought of Harry's giant cock inside her pussy.

Hermione took Harry closer to the bed and dropped down to her knees. It looked like a pillar had been shoved down the leg of his jeans. The stitching was straining dangerously. Hermione smiled and reached up to the button. She pulled them open and slowly pulled Harry's jeans around his ankles. A twelve-inch long pillar of flesh rose up and stood to attention. It stood just above Hermione's left shoulder thick and throbbing. Ginny gasped loudly and it wasn't because of the wand in her pussy.
"The stories are true." She said breathlessly. Hermione glanced back and nodded. Then Ginny looked scared.
"You can't be serious." She yelled. "He won't fit."

Hermione smiled and shrugged her shoulders.
"Enough of him will."

She fell silent as she turned her attention back to Harry's staff. She wrapped her hands around and began to stroke his thick flesh. Harry gasped and almost fell, but managed to make his knees hold out. Hermione rubbed at his tip, where Harry seemed to get the most pleasure. She rubbed his throbbing purple head and smiled as Harry gasped and groaned loudly. Hermione's arm pumped rapidly and held tight, yet gentle. Just how Harry liked it. His balls tightened and he felt a pressure growing into his shaft.
"I'M GOING TO CUM!" He cried out.

Hermione had been waiting for this. She clamped her mouth onto the tip of his cock and gave it a rapid tongue bath. That was too much for Harry and with a loud cry his balls exploded into Hermione's mouth in long hot torrents. It wouldn't stop coming. Hermione tried to keep it all in her mouth, but some leaked out the sides and dribbled down her chin.

Harry fell to the floor as his knees buckled from under him and his dick fell out of her mouth. A couple of small spurts shot out of his cock and dribbled down his long shaft. He was already beginning to be shrinking back down to normal.

Ginny had got so hot watching the perverted act. If she could reach, she would have been fingering herself like there was no tomorrow. The wand was making her feel great, but it was working too slowly to bring her to satisfaction.
"Somebody give me some attention, or I'll scream." She practically yelled.

Hermione swallowed Harry's cum and smiled as she felt the hot cream run down her throat. She climbed onto the bed and slid herself in between the giant breasts and managed to reach Ginny. She kissed the young red head on the mouth. Ginny could taste Harry's salty cum. She liked the taste.

Hermione pulled the wand out of Ginny and the girl groaned at the feeling of emptiness that replaced her insides. Harry began to make his move, but Hermione held out a hand and stopped him.
"Just sit and watch." She said. "It's not your turn yet." She said seductively and turned her attention back to Ginny. She tapped her fingers lightly on the giant breasts. They sounded like a bass drum and jiggled like water balloons.
"Time to milk this cow." Hermione joked. She nipped one of the two-inch long, rock hard nipples, between her fingers. Ginny gasped and smiled at Hermione.
"More." She gasped.

Hermione positioned herself and took the long tit into her mouth, the intruder reminded Hermione of sucking on a finger. Only this finger was boneless and cold be squeezed and moved by her tongue in a way no finger could. It tasted different too.

Ginny was in heaven. With the giant tits came giant nerves and giant feelings with them. She thought her brain was going to explode as titanic wave after wave crashed her brain. She groaned loudly and couldn't catch her breath, her lungs just weren't big enough. Hermione sucked hard on one nipple and rubbed the other gently. The space between the two tits was so great that Hermione could only just reach.

Harry began to get hard again. Ginny was groaning loudly in the throws of ecstasy. Both girls were soaked, their pussy's were dripping juices and soaking the bed. Harry was fully hard and couldn't leave it alone. He was throbbing painfully and demanded attention. He gripped the shaft and began to slowly stroke up at down the throbbing mass.

Ginny screamed as an orgasm racked through her body. Just having her giant tits sucked was enough to drive her to ecstasy the nerves were that sensitive. Hermione stopped sucking, much to Ginny's disappointment, and turned to Harry.
"Now, it's your turn." She said seductively.

Harry needed no further encouragement. He practically leapt onto the bed and wrapped his arms around Hermione, pulling her close into a passionate kiss. He gently pushed his tongue forward and she allowed him in. Their tongues wrestled for several seconds and Hermione pressed close, squashing Harry's large dick between her breasts. Hermione broke the kiss and pressed her ample cleavage together and moved herself up and down.

Harry groaned and fell back onto the bed. Hermione gripped his dong gently and held it straight up. Standing over Harry she positioned herself and took a deep breath, preparing herself for the giant invader.
"No fair." Called Ginny. Hermione and Harry turned, her pussy was dripping and she was rocking back and forth in mad efforts to either reach her pussy and finger herself, or reach Harry and use him pole to impale herself. There really was no way of knowing. "You've had him before, I want to try him."

Hermione looked slightly disappointed, while Harry didn't care either way. He just needed to get some release soon before he went insane.

Hermione nodded slowly and moved herself away. Harry sat up and positioned himself between Ginny's massive mounds of flesh and with a little Held from Hermione, his cock was placed right at the entrance of Ginny's dripping pussy. Harry was about to slide in when he caught sight of Ginny's frightened expression.
"If you don't want this, it's alright." He said gently, but Ginny shook her head furiously, making her breasts jiggle.
"Just be slow." She said.

Harry nodded and thrust himself slowly forward. Ginny gasped as her insides were stretched and bit her lip so hard that it bled when Harry popped her cherry. At five inches Harry couldn't go any further, Ginny was too tight, or he was too big, or both. A couple of tears ran down Ginny's face and she gritted her teeth. Harry hesitated, he knew that it was supposed to hurt for girls the first time and would wait until Ginny was ready to go before he could move on.

After half a minute Ginny nodded her head and Harry began to move again. Ginny groaned loudly as Harry invaded her insides. Still only five inches, but it was enough for both of them. Ginny's tits shook violently shaking like giant water balloons. Harry pulled almost all of the way out and thrust five and a half inches into her. Ginny groaned in deep pleasure.

Hermione grabbed her wand and muttered a spell that made the stick of wood vibrate in her hand. She rubbed it at her folds and teased her entrance. She bit her lip and groaned as she slowly slid the wand inside her.

Harry rammed himself into Ginny and six inches went into her. Ginny moaned Harry's name loudly and dug her nails into his shoulders. Harry growled and pumped Ginny harder. Which made Ginny cry out in ecstasy.

Ginny felt a pressure growing deep in her cunt. Harry's rhythm became slightly frantic and she knew he was close too.
"FASTER." She screamed out loud. Harry doubled his efforts and humped Ginny as fast as she could.

Ginny felt her body stiffen for half a second. She couldn't even breathe. Then the orgasm hit her and she threw her head back and screamed Harry's name loudly as her pussy tightened and squirted juices onto the sheets. The sudden tightness threw Harry over the edge and his balls exploded, firing squirts of hot cum deep into Ginny's insides.

Harry slowly slid himself out of the young girl, her pussy juices coated his dick and shone as they slowly dried.

Ginny smiled, satisfied. Her eyes were half closed and she looked like if she could, she would kiss Harry.

There was a moan over his shoulder and Harry saw Hermione rapidly trying to bring herself to orgasm. She moved her vibrating wand in and out of her pussy. Harry grabbed her hands and moved them out of the way. Hermione looked at him, both confused and flushed with sexual excitement. Harry gripped Hermione's wand and pulled it out. She groaned angrily as the emptiness filled her pussy.

Harry pointed the wand at himself and performed a potency charm on himself. Instantly his dick began to harden again and was back to twelve inches in seconds. He tossed the wand aside and Hermione opened her legs as wide as she could. Harry positioned himself and slid his way into Hermione's soaking folds.

Her muscles clenched once and she groaned loudly at the sudden invader. Quickly she relaxed, Hermione had had Harry inside her once before, it didn't take her long to be used to his size again. She ground her pelvic bone against his.
"Ah, god" he exhaled.

He worked his hand up towards breasts and lightly rolled a nipple in between two fingers, she sighed.

She lifted her hips up again and proceeded to wrap her legs around his waist. All twelve inches of Harry was pulled inside her. Hermione screamed in both pleasure and pain as her innards were stretched to their limits. Every nerve ending in her cunt was on fire and she drove her nails into his back.

Both Harry and Hermione were close to orgasm. Hermione from her actions with the wand and Harry had already cum once. The potency charm could restore an erection, not reset your stamina. Already he could feel his balls tightening and a pressure building in his gut.
"Faster...Harry...I'm close." Panted Hermione between deep, passionate breaths.

Harry pulled all but an inch of his dong out and rammed back into her. The feeling of being empty and then filled so quickly pushed Hermione to a strange level of ecstasy and she felt breathless. She couldn't know up from down or even her own name. It felt like her insides were about burst. Harry's dick was so large that she could practically taste him. Her cunt exploded and tightened, clamping tightly onto Harry's cock, holding it tightly in place.

Again the tightness sent Harry over the edge and his balls exploded, filling Hermione with his thick hot cum. Hermione felt it spreading through her womb and coating her insides.

Harry collapsed onto Hermione, his energy drained and his dick slowly shrinking back to normal. He rolled aside and lay next to Hermione. His dick glistening with both girl's juices and his body shining with sweat. He slowly tried to catch his breath.

Ginny had grown horny again watching the couple fucking. If she thought Harry or Hermione was up to it, she would have demanded them to make love to her.

There was a sudden sound, like air leaking out of a balloon. This caught the attention of Harry and Hermione and they glanced up at her.

Ginny's tits were shrinking back to normal, se stared at the deflating and felt the pressure on her back easing off. They were already the size of beach balls and Ginny found that she could move again, not actually get up, she was still too top-heavy for that.

Down to basketballs. Finally she could move properly. Ginny moved herself between Harry and Hermione. Her breasts returned to their normal C-cup and she looked from Harry to Hermione. She leaned forward and kissed the girl and reached down and griped Harry's balls in her hand.
"Anyone feel up for another round?" She asked seductively.

Hermione cupped Ginny's tits and gave them a playful squeeze. She thought they felt better not she could get her hands on them both without needing to stretch. Ginny moaned lightly as Hermione squeezed her hard nipples and Harry kissed Ginny's stomach, and began to make his way down lower.
"Wait." Hermione's voice called. Harry stopped and looked up at Hermione as she dived into Ginny's trunk and pulled out the jar of charmed moisturiser. She opened the jar and took a large dollop, spreading it onto her tits and spread some onto her clit and even slid her finger inside her wet pussy, making sure she coated as much of her insides as she could reach.
"Hermione, are you nuts? You saw what happened to Ginny's tits with only a little of that stuff." Harry said, obviously too late to stop her, it had been a mixture of shock and morbid curiosity that had kept him silent.

Ginny on the other hand seemed to be thinking along the same lines as Hermione. She grabbed the jar out of Hermione's hands and did the same thing to herself, moaning loudly as she inserted her fingers into her tight cunt. Harry tried to stop her but Hermione had jumped onto him and kept him at bay until Ginny was done.

Ginny glanced into the jar of moisturiser, there was only a tiny bit left in the bottom. She smiled at Harry sneakily. He was pinned to the bed with Hermione sitting on his chest. Ginny grabbed her wand, it was sticky from her dry pussy juices, but Ginny had other things in mind.
"Petrificous Totalus." She called triumphantly, pointing her wand at Harry.

Hermione moved off of Harry as his hands and legs snapped together, paralysing him like a statue. Hermione looked at the jar in Ginny's hands, glanced at Harry and smiled.
"You little, perv." She laughed at Ginny.

Ginny shrugged her shoulders and scooped up as much of the cream as she could.
"You're just jealous you didn't think of it first." She said as she spread the moisturiser onto Harry's dick and balls. Hermione wiped her hands clean on the bed sheets, not wanting to end up with giant fingers.

Hermione took her wand and released Harry from the spell. He said nothing, knowing it was already too late. Hermione and Ginny found a place on the floor, knowing they wouldn't fit on the bed once they had grown. They sat near each other with their legs wide open and their backs resting against the footboards of other pupils beds.

He gasped as Hermione and Ginny's chests began to swell. But there was growth between their legs. Their clits were swelling out of their pussy's pink and throbbing, already six inches long and still going. Harry knew similar growth was going on inside the girls. They were making themselves bigger for the new him.

Harry's balls swelled up quickly. He fell back onto the bed as the swelling feeling took over his crotch. It felt like being pushed around, from the inside. His balls swelled up to tennis ball size and still kept going, his soft cock grew from its normal, since the potion accident, six inches to eight. To ten. To twelve, to fifteen!!!

Harry stood up. Hermione and Ginny had nine-inch long clits, bright pink and throbbing with dark veins. Their pussy's were large, with almost two inches of skin coming away from their cunts. Harry could only imagine how much more space had developed inside the girls. Puddles of cunt juice were spreading across the stone floor. Both Hermione and Ginny were pinned in place by tits the size of Mini Coopers. But neither girl minded when they saw the size of Harry. In fact they were rendered speechless.

His balls were the size of basketballs, covered in a fine coat of short, dark curly hairs. His dick hung at fifteen inches long as was completely soft, but at the sight of the two giant pairs of tits and the beautiful horny girls attached to them, he could feel a familiar pumping feeling as he began to grow hard.

Even when the stories of their adventure spread around the school, no one ever believed a word of it. It was just too far-fetched, even for Hogworts.
