Author's Note: The first two chapters on this story were written as one-shots before I decided to take the story in a different direction. The story will now follow a single narrative detailed in the first chapter which is the third entry on the story. Please read the author's note there for more information. The first two chapters will not be removed, but have been rattled as 'Proof of Concept' and are completely detached from the main story. Thank you.

On an additional note, this story was inspired by Futadom's brilliant story, 'Harry Potter Futanari one-shots'. Go check it out!

Proof of Concept: Observations In The Owlery

Hurrying into the room, Harry batted the thick snow that had accumulated on his jacket to the floor. Scuffing his boots along the ground he knocked the snow onto the ground. Rubbing his hands together he tried to warm himself, but to no avail. With shaking and shivering hands he fumbled around in his pockets, retrieving a small handwritten letter. Holding it close, he looked up into the tower his eyes searching for the snowy white owl, "Hedwig! Hedwig!"

With a flurry of white feathers, the snowy owl drifted slowly through the air before hooking its claws around Harry's arm and preening her feathers. Gently stroking his finger over the bird, he took the letter and held it for the owl to take into its beak. Taking the letter, she shook her head before taking flight and flying up through the tower. Smirking to himself, Harry turned and gasped slightly in shock. He was taken aback by the sudden appearance of someone in the doorway.

"Cho," Harry stuttered as the Asian girl suddenly appeared in the doorway a letter in her hands. Awkwardly smiling at her, Harry found it difficult to formulate words and simply blushed as Cho smiled politely before entering the room.

"Hey Harry," Cho smiled awkwardly as she crossed the room and held her arm out for her owl, "Sending a letter?"

"Eh… yeah," Harry said twiddling his thumbs as his face burned bright red. Stupidly he refrained from saying anymore and simply stay quiet casting fleeting glances over at the girl. Harry had admired the girl, the curves and beautiful features of the Asian girl. She was beautiful. A cute and smiling face and an incredible body. She never revealed much, but Harry would tell she had a nice pair of perky tits and her ass fitted snuggly into her clothing. Right now she was wearing a pair of dark blue jeans with ugg boots. She wore a grey jumper with a blue body warmer on top.

Cho let her owl fly away with her letter, before turning to Harry a smile on her face once more. She waved playfully before striding to the door, "See ya Harry."

"Bye Cho…" Harry said a thought flickering in her mind. This was his opportunity. With the Yule Ball around the corner and his lack of a date, this was his chance to remedy this. He wanted to ask Cho, but he was nervous, shy. Breathing deeply he turned and called to her, "Well, l just wondered if you. I wondered if maybe you wanted to go to the ball with me?"

"Eh… I'm sorry… Cedric already asked me…" Cho said awkwardly as Harry tried to hide away. Those words stabbed like daggers for some reason. He was hoping she would say yes, but not that Cedric had asked her. The two shared an awkward moment, before Harry broke the silence.

"Oh… that's okay… yeah fine," Harry said turning away shielding his embarrassment as Cho entered the room in a panic.

"Harry! I'm sorry," Cho said rushing over to him and grabbing his arm pulling him to look into her eyes, causing him to blush even further, "I really am… I feel terrible. Can I make it up to you?"

Harry stuttered for words as Cho did something unbelievable. Their eyes locked and a strange feeling flooded over his body. Something flickered in Harry as Cho looked into his eyes. Funnily enough, she could feel it too and it was burning inside her chest. In a moment of unbridled passion, she leant in and let her lips pressed softly against his. Tentatively she pulled back, but realized her folly and leant back in to press her lips firmly against his. Her arms wrapped around his neck pulling him in closer and deeper.

Utterly bewildered, Harry could do nothing, but simply melt into the kiss allowing Cho full access to his mouth. Her tongue pushed inside battling and winning dominance over his complacent tongue. Pulling him close, Cho pressed her chest against his, her breasts squashed against his chest, her erect nipples protruding through her clothes and poking into his chest. Snaking a leg around Harry's, Cho pulled her crotch against his and immediately pulled back.

"I'm sorry! I can't do this," Cho said immediately turning her back and hiding something from Harry. Adjusting her trousers, she kept her back turned confusing Harry even further.

"What? What's wrong," Harry asked a little bolder now after Cho making the first move.

"Nothing's wrong! Well… something, but… you… can't know…" Cho said her hands covering her crotch even though it was beyond Harry's sight.

"Cho… you can trust me…" Harry said, remembering something Seamus said. Apparently it worked well on girls. He would see, wouldn't he.

Sighing deeply, Cho turned around and lifting her hands, her face red. Standing there she waited for Harry to notice. Looking down at her crotch, Harry had to stifle a gasp as he saw what she was trying to conceal. Pressing against her tight jeans was a thick bulge stretching the fabric immensely, "I know! It's horrible. Disgusting!"

"No! No… no… I'm sure it's beautiful," Harry said, not quite realizing what he was getting himself into. In his kindly attempts, he tried to make the girl feel confidant and not embarrassed about the addition to her person she had. However, he realized his folly when Cho, in frustration, undid her jeans and pulled the denim down along with her pink cotton panties. Harry's jaw dropped as he gazed upon her tool. It had to be twelves inches and at least three wide. It was hairless and a huge ball sack dangled beneath her throbbing shaft as pre-cum seeped from the tip of her engorged length, "Wow! It's… it's stunning…"

Harry spoke the truth. Despite proclaiming himself to be straight, he found something oddly appealing about Cho's cock. It was enticing him and as he stared longingly at the cock, he felt his own length harden. Perhaps it was the hot Asian girl attached to the cock, or perhaps it was indeed the cock itself that was birthing these strange feelings of arousal, "Really? You think so?"

"Yeah! Everything about you is beautiful," Harry blurted out trying to comfort the shy and horny girl, "It's just another beautiful part of you."

"Oh Harry! You're so sweet!" Cho said rushing over to him, her huge cock bouncing as she did so. Pulling him in close, she trapped her length between their bodies, her head oozing a drop of pre-cum onto their clothes as she pulled him in for a deep passionate kiss. Her tongue slid back into her mouth as her hands reached down and cupped his pert young buttocks, pulling his hips even closer. She could feel his cock press against her. Giggling into Harry's mouth as she felt his bulge rub against her leg, she quickly realized just how small he was compared to her. Yeah he was seven inches which was commendable, but he seemed tiny when held up against her monster. Sliding her jeans of as she kissed Harry, she stood there with no bottoms on, he feet pressed against the cold stone. Pulling her lips away from his she smiled, "Erm… could you give me a hand… you know… making this go away?

"Uh… sure," Harry stammered surprised at Cho's sudden forwardness. Was she really suggesting what he thought she was. He was going to get to fuck Cho Chang. His cock twitched a throbbed at the very idea, pushing against his jeans painfully. Chirping in excitement, Cho rested her hands on his shoulders and slowly pushed him down to his knees. Startled, Harry began to panic, "Erm, what?"

"Thanks for this. Doing this by hand takes hours," Cho smiled, ignoring Harry's frantic stammers. Holding the back of his neck, she brought him close, her cockhead inches away from his mouth. Moaning to herself as she felt his hot breath on her cock, Cho took a hold of the base of her cock. Trying desperately to wrench his head from Cho's grasp, Harry could do nothing but look on as Cho brought her cock closer and closer to his lips. Keeping his mouth clamped tightly shut, he saw her cock graze his lips.

Moaning loudly, Cho pressed her tip against his lips, sliding it back and forth, painting his lips with her pre-cum until they shimmered with a shining gleam. Grumbling, Harry let a dribble of her pre-cum seep into his mouth. The taste startled him and he instinctively opened his mouth to get rid of it allow Cho a chance to slide inside. With one push she lodged a couple inches in his gargling mouth, flooding him with her salty, musky pre-cum. Spasming and flinching, he tried to push her away, but Cho was simply too strong. Both her hands grasped the back of Harry's head tightly, softly caressing his head as she sunk her length into his mouth. Moaning, she reveled in the tight warmth of her new toy's mouth. Her cock stretched his lips tightly around her shaft as her cockhead rested at the entrance to his throat.

"Oh Harry, you are simply divine. Your mouth is so warm and wet!" Holding her cock in his mouth for a moment, she began to thrust her hips back and forward moving the few inches she had buried in his mouth, back and forth, his saliva coating the portion of her length. Every time she pushed further forwards, Harry's throat would deny her access, clenching and constricting preventing her from sliding her cock deeper into the young boy, "Come on…open up! Let Cho come in!"

Harry's mouth was filling with saliva and pre-cum, to the point where it was bubbling out of his mouth a streaming down his chin, adding to the sloppiness of the blowjob. Deciding to swallow, he soon noticed his mistake. As he swallowed, he opened his throat slightly allowing Cho's head to slip past and the tip to slide into her throat. Gagging he tried to push her cock out of her throat, but was unable as she had already made it past. His throat spasmed as she groaned loudly, her hands gripping his head tighter. Holding him steady she moved her feet forward and then slowly thrust her hips forward, easing her cock down Harry's throat in one long continuous push. Unable to fight back, Harry felt his throat stretch and flex to accommodate her thick length. Choking on her length, he quickly learnt to breathe through his nose her tip pressing against the back of his throat. His lips pressed against her soft, smooth and shaven crotch, his nose pressing into her skin as the entire cock settled inside his mouth.

"Good boy…mmm. You are simply delish!" Cho grunted as she held his throat down on her cock, loving the tight wetness of his fluctuating and Spasming throat. Her massive, bulging ball sack slapped against his chin as she felt pleasure surge through her body, his tongue wrapping unconsciously around her pulsating shaft. Trying to steady his position, Harry leant around and let his hands grab her plump, fleshy arse cheeks and fondling her ass. The groping hands of Harry, simply added to the sensation of pleasure rushing through her tingling body.

Pulling her cock back, she began to thrust and fuck his tight throat. Holding his head steady, she pounded back and forth, her cock twitching and pulsating as she fucked him. The warm saliva rushed down her cock as she slid back and forth, her orgasm edging closer and closer. Suddenly her cockhead erupted in pleasure, spurting her cum down his throat, flooding his throat with thick white cum. Groaning loudly, she pulled her cock from his mouth, watching as he coughed up cum, dripping down his chin as he swallowed what he could and spluttered the rest across the floor.

"You did well, Harry," Cho murmured, jerking her cock, spreading saliva and cum along her length, "Now for your pleasure."

Grabbing Harry by his hips, she flipped him onto his hands and knees and took her cock in hand. Harry complied, still trying to catch his breath. Not even thinking about what she meant, Harry felt Cho's thick cockhead press against his arsehole, smearing her cum and saliva covered tip along his puckered hole. His eyes flew open as he panicked, "No! Cho… it's too big!"

Ignoring his cries for her to stop, Cho sunk her hips down, his tight hole constricting and preventing her from attaining her entrance. Chuckling slightly, she took a hold of his hips and slammed her cock forward submerging five inches in his tight clutching ass. His mouth fell open, ready to let out a scream, but her couldn't make any noise. The thick cock stretched his asshole to new extremes as she continued her assault. She had been consumed in lust and desire, sliding her cock deep into his ass, desperate to cum again. Grunting as she forced the last few inches into his ass, Cho moaned watching as Harry dropped his head, his face scrunched up in pain as he panted feverishly trying to adjust himself to the thick, throbbing length now forcefully invading his ass.

Her shaven crotch pressed against his bare arse as she began to pull out. Sliding her cock back through his ass, she pummeled his prostate, sending shockwaves of pleasure through his sex ridden body. Slapping his ass cheeks, she pulled out until only her thick cockhead rested inside, before slamming her hips forward, burying the entirety of her length inside his ass, mashing his prostate against her cock, squeezing every last ounce of pleasure from the boy's body. Speeding up her lusty thrusts, she made sure to draw all the way out before sliding back in adding pleasure to Harry's pain. He was grunting alongside her moans and was slowly starting to enjoy the cock lodged deep in his ass. Cho built up quite a rhythm pounding her cock back and forth with relative ease now that she had loosened him up

Pumping her hips forwards, she buried her cock entirely in his tight arse, his tight clutching hole, milking her cock for all it was worth. His hole flexed and tightened around her cock, causing her to moan loudly as he cock spasmed and twitched inside his ass. As he shaven crotch slammed into his ass cheeks, her cock erupted spurting out half a dozen strands of long thick cum into Harry's arse. Groaning loudly as he felt her cock unload into his ass and fill him to the brim with cum.

Pulling her cock out from his ass, she moaned loudly and watched in awe as her cum dripped from is tight ass. Smacking his ass firmly, she pulled and squeezed his flesh before watching him collapse onto the floor exhausted, "Oh you are delicious Harry. Cedric will love you. We have to arrange a time when we can both play with you, my little buttslut."

Only able to grunt in response, Harry lay there, cum seeping from his ass as Cho gathered her clothes together. His cock twitched and spurted cum across the floor as a smile edged across his face in contempt. Although he felt slightly violated, he loved the feeling of being used and left as a cum dump. Perhaps fun with Cho and Cedric would be fun.
