Chapter 4- The Joys of Transfiguration

Harry was intrigued with the idea of Carling's proposal; it spurred him post tryout times that very night on the bulletin board, which caused quite a bit of commotion in the common room. Tryouts would be on Saturday and by morning the board was already full of candidates. Harry did note that Ginny had put her name down for Chaser, as well as Demelza. Cootes, Peakes, and Ron had all put their names down for Beaters and Keeper respectively.

Thursday had Harry in Potions again in the morning. They worked on a hair growing potion, it was designed for shaved cats or small animals according to Slughorn but Harry wondered what would happen if a few drops were put on the human body. He again nicked a bit of the brown liquid into a vial and stored it away in his robes.

After lunch Harry went to Professor Heartstring's office for his individual lesson. She greeted him warmly, offered him some tea and went into what they would be covering together over the year. She as well was not in her typical robes, but in a plaid skirt that hemmed just over her knee and white blouse that was unbuttoned just enough to show her cleavage which was pushed together with a lacy black bra. Her hair was up in a delicate tangle held by what looked like chopsticks and her green eyes sparkled behind her black rimmed glasses.

By the end of the year Harry was to be able to transform his body into someone unrecognizable from his current self.

"We are going to try this in steps, the first will be growing and shrinking yourself," explained Professor Heartstring.

"Of course Professor," replied Harry.

"Harry, please call me Tatum when we are in here together, Professor makes me sound old,"

"Of course Tatum," replied Harry.

She showed him how to grow his finger nails and control how long they got. She explained there were limits to what you could do based on the matter and material you were changing but it was possible to double the size of certain parts of the human body.

"On any part?" Harry asked.

"Well, for the most part, you can't double the size of your internal organs, trust me don't try to- many good Wizards have killed themselves by trying to increase their brain size or make their heart stronger. But most outside parts can be adjusted as well as hair or fingernails. You cannot change yourself into the opposite sex, only polyjuice potion can do that," she answered.

She gave a demo making her hair shorten and turn red, her height shrink about 5 inches, and her bust grow in size to almost popping out of her shirt. Harry's mouth dropped, she looked like Madam Rosmerta from the Three Broomsticks pub.

"Not bad eh?" Tatum asked.

"That's amazing, can I try?" asked Harry.

She agreed, but offered to Harry he might want to take his robes off so they could see the difference in what he was doing. He took off his robes to reveal just maroon plaid boxer shorts. Tatum did a double take at his defined abs and the wispy hair on his chest. Harry make his arms grow bigger slowly, and then had his hair shorten an inch or two and turn blond.

"Good Harry, very nice, can you make your legs grow any?" she asked.

He pointed his wand at his legs and performed the spell. Quickly he discovered he must have made a mistake, his legs did begin to grow but the feeling in his groin told him his cock was growing as well. It snaked out of his boxers and Tatum gasped. Harry had grown a few inches larger in both his overall size as well as his cock size. He looked up to see Tatum smiling at his cock; she looked up and said to him, "Well done now you are a very big boy! Let's see how you did," and she gently pulled his shorts down to reveal a long thick ten inches of Harry's manhood dangling between his legs. Tatum grasped it, flexing it in her delicate hands. Harry couldn't help it, his cock began to harden, which only made it bigger, it soon was 12 inches hard and now facing up towards Tatum in its fully erect glory.

"Well, well, what a good student you are, I'm not sure what we are going to do with that, but I think we will have to make sure it's fully functional!" she whispered to herself, her eyes focused downward.

It began almost immediately, Professor Tatum Heartstring was on her knees sucking on this gigantic cock Harry had transformed onto his body and it felt amazing. Tatum didn't have to cast any spells that Harry could tell she was sucking Harry like he couldn't believe. Her head was bobbing up and down on his cock, her hands now on his pulling them toward her breasts which were already straining against the fabric of her shirt and bra.

His fingers quickly released her shirt and bra and removed them, her breasts literally popped out and his hands roamed over them, stopped to softly pinch her large nipples. She moaned in pleasure at his touch, her mouth full of his manhood. Harry couldn't believe this was happening he had never expected this kind of reaction from the staff at Hogwarts. Tatum licked his cock like a big lollipop and looked into Harry's brilliant green eyes.

"I need to ride this cock like a broomstick," she demanded.

She stood up and had Harry sit down on a plush chair in front of her desk. She then turned around and grabbed his cock through her legs and backed into his hard on. Tatum started grinding back into him while guiding his hands to her nipples. She was tight and super wet once his cock slide into her, his hands roamed from her large nipples down to her trimmed pussy, rubbing her clit as his cock slid in and out of her. She rode him hard, in his head a fantasy of actually fucking while riding on a broomstick came to mind that he quickly filed away for another day.

"Oh yes Harry, fill me up with that cock!" she screamed.

He obliged and quickly decided he needed to take control of this situation after her third very vocal orgasm. He pushed her forward so she had her hands on her desk bent over and stood behind her.

"I'll do anything you want Harry, just fuck me hard!" she purred.

Harry's cock rubbed Tatum's asshole gently at first and she gasped, but her ass pushed against his dick in a clear acceptance to his intentions. He slid in slowly and her moan became a constant note that didn't break until he was deep inside her.

"I want you to cum in my tight ass Harry," she whispered.

"I'm going to cum all over you professor," Harry replied with a smile.

He fucked her hard, her screams must have been heard in the hallway outside her classroom, but Harry didn't care. Tatum's ass shook with his thrusts and after she moaned a deep guttural moan he pulled out of her and sprayed her with his cum, shooting sticky gobs onto her ass, her back, her hair, and by the time she turned around into her open mouth.

"Oh my god Harry, that was spectacular!" said Tatum. "Now, you go get yourself cleaned up, you get an outstanding grade for this lesson."

With cum dripping off her hair, back, and ass Professor Heartstring left him and went into her personal chambers to clean up. Harry got dressed again and transfigured back to his normal height, but kept his cock at its big size. Smiling to himself he walked the corridors absent mindedly, walking into Ron coming around a corner.

"What the hell was that noise coming from Professor Heartstring's room a minute ago?" he asked Harry.

"Oh that, nothing to worry about Ron, just the Professor Orgasming after the deep ass fucking I just gave her," Harry said casually.

Ron's jaw had to be scooped up off the floor, Harry started to laugh.

"Your joking Harry," Ron said timidly.

"I'm not, right now Tatum, that's what she asked me to call her when I fuck her, is washing my cum out of her hair," Harry said.

Harry then told Ron all the details from his one on one with the Professor. Ron's eyebrows were lost in his hair and his mouth was once again agape once Harry was done. Harry laughed again at Ron's expression, and told him to have fun on his one-on-one tomorrow.

"Do you think she'll be that way with every guy?" Ron asked.

"Now, now Ron, what would Hermione say if she heard you say that?" Harry scolded him mockingly.

"Happy I was participating in class?" Ron answered laughing.

Harry told Ron he was going to take a bath in the prefect bathroom and said he'd see him later that night. Harry walked to the special bath and gave the password "Felix felicious" to the door. While not a prefect, Harry did have access to this pool sized bath because he was a Quiddich Captain. He paused right away though because he heard voices and people talking inside. That was odd he thought, usually this room would only allow one person at a time to enter, maybe they had forgotten to lock the door after entering, and whoever was here must of come in together. He remembered his invisibility cloak was in a pocket of his robes; he quickly threw it over himself and walked into the large room that held a gigantic bathtub the size of a swimming pool. A girl was on her hands and knees on the tiles at the side of the tub, her ass hanging over the water, she was facing away from Harry who noticed the second person was waist deep in the water, his blond hair was wet back, his tongue buried in her ass. The water came to his buttocks and was opaque with colored bubbles.

"Oh Draco, yes right there, lick my tight asshole fuck me with your tongue," moaned a familiar voice echoing in the large tiled room.

The ceiling was tall and arched and covered in small glass tiles of aqua, blue, silver, and white. A beautiful mermaid in a stained glass window filtered the outside light, but the skies were darkening and some candles had been lit that cast the room into faint shimmers that reminded Harry of being deep under water in the lake outside.

The girl was on the heavy side, her dark wet hair covering plastered to her back, she had large breasts that hung down almost to the tile that Harry could see from angled view he had of her. She had one hand holding her steady and the other was furiously working between her legs at her clit.

"Mmmm, Pansy, like this? Do you really like it sweetie?" asked Draco Malfoy in his signature drawl but lacking the sarcasm that often lingered in his verbal jabs. Harry noticed he was stroking himself with one hand while squeezing Pansy's ass with the other.

"Mmmm, Draco, I'm almost ready for you, give me a few more minutes of this baby," Pansy whimpered.

Harry kept walking around the pool silently, the sounds of echoing water from a few of the running taps and Pansy and Draco's voices filling the room. Harry stopped walking when he was about ten feet from the pair. Now he was on Pansy's side of the pool, her nipples were hard and large silver dollars with dark areolas'. Her eyes were closed in concentration, her breathing heavy and labored. The usual look of wicked delight she had in gossiping about other students was gone and she looked very strained and lonely crouched on her hand and knees.

Harry could see Malfoy still stroking his cock, it was thin but average size but Harry was surprised at Draco's body, it looked so pale and frail in the dim lighting.

"Oh shit!" Draco moaned as he shot a load onto the tile between Pansy's legs.

"Draco! What the fuck?" yelled Pansy whose head had dipped down to see what had happened between her large thighs.

"I'm sorry Pansy, I just got too excited," mumbled Draco.

"Get out!" yelled Pansy.

Draco looked as if he was going to retort, but he instead turned around and swam the width of the pool and got out dripping and limp. He grabbed his wand and dried himself off and grabbed his robes from a hook on the far side of the room. The door slammed shut as he left.

Harry was amused but at the same time felt pity for both Draco and Pansy. She slowly rolled over on the tiled floor, her naked body relaxing and her breathing slowing down.

"Fucking loser," she quipped. "Why is he the only idiot in this place who fancies me?"

Pansy eased into the water slowly and floated on her back across the water, parting the bubbled filled water slowly with her large hour glass form. Harry decided he would pretend to walk in on her on accident; he walked back to the entrance and flipped off his invisibility cloak. He then walked back into the bath and removed his clothes quickly. He was dipping his toe into the water when he heard Pansy gasp. Looking up in mock surprise Harry saw Pansy's face enveloped in bubbles, the rest of her was beneath the surface hidden.

"Oh, sorry, didn't know anyone was here, the door was open," said Harry.

Pansy's face went from rage to stunned silence as she looked over Harry's naked body, her eyes becoming unfocused as she took in his large limp cock that hung halfway down his thighs. He returned her gaze and a smile crept over his lips.

"Parkinson, what's wrong you never seen a naked bloke before?" asked Harry. "I figured you and Draco would of gotten this far by now."

Pansy's eyes came back into focus and she murmured, "Yeah well he is different."

"Different? Is he missing something?" Harry laughed.

"No!" she immediately yelled but she then said very quietly, "No, he is just not like you."

Harry began to walk down a small flight of steps into the bath.

"What are you doing?" asked Pansy in alarm.

"Taking a bath Parkinson," replied Harry, "do you have a problem sharing the bath with me?"

"I guess not, um, but I have nothing on either," said Pansy. "What will your girlfriend Ginny think if she knew you were in here with a naked girl?"

"I thought you were a good gossip Parkinson, Ginny and I are on hiatus, I'm a free agent, plus I've seen my share of naked girls" replied Harry.

With this news Pansy couldn't hide the smile which flashed over her lips for an instant. Harry jumped into the warm bubbly water and did a lap across and back. Pansy stayed in her bubbles and simply watched him. Harry began to float on his back, aware that his cock draped over his leg as he kicked softly. He circled Pansy in wide circles; she stayed submerged up to her neck and turned to watch him curiously.

"So are you and Malfoy together?" asked Harry casually.

"That's none of your business," said Pansy.

"So I suppose he would mind if he found out you and I were in here together," asked Harry.

"You better not or I'll tell everyone your, your…" she trailed off thinking hard for a comeback. "You think your so great Harry Potter, such a big man, so powerful that you killed the Dark Lord, so cool and everyone loves you and all the girls want to be with you."

Harry stopped floating and looked at Pansy hard, and then he smiled again and said, "I don't think any of those things Pansy, but I think you do."

Pansy's scowl faltered, she turned pink and swam away from Harry. She quickly pulled her body out of the pool and ran to her robes across the room, her ass jiggling with every step. Harry watched in amusement and as the door slammed he turned and swam another lap.

Friday had Harry in Charms all morning and by the time his free period came about after Lunch Harry was exhausted from his first week. He wished Ron good luck in his individual Transfiguration lesson and watched his friend climb out the portrait hole. Ginny was in a deep conversation with Pavarti and ignored Harry's glance toward her. He went upstairs and fell asleep, waking up when Ron shook him awake.

"Harry, she's a bloody whore!" Ron whispered to him.

"What, who is, what are you talking about?" said Harry through a yawn rubbing his eyes and grasping for his glasses from his table next to the bed.

"Professor Heartstring, I just got done with my individual lesson, and she was all over me," said Ron in a hushed but excited voice. "We had barely started the lesson when she had showed me how she could transform her body, made herself look like..."

"Madam Rosmerta?" interrupted Harry.

"What? No, she made herself look like a Veela, you know long blonde hair, kind of like Fleur, but with big breasts and long legs," said Ron quickly. "Did she make herself look like Rosmerta for you? Merlin's pant's, I would of cum right then if it had been me. Anyway she transformed herself and then had me take off my clothes so she could make sure I was doing everything right and all of a sudden she's tearing off my boxers and on her knees giving my wand a good polish."

"Did you bang her?" asked Harry.

"She sucked me so good I came in her mouth; she swallowed it all down too. I felt stupid but she just told me I tasted like candy and she couldn't wait to get another mouthful next week," said Ron. "I feel bad, like I should tell Hermione."

"Gee Ron, sounds like a great idea, you should definitely tell Hermione that Professor Heartstring gave you oral and now you feel bad about it, see if Hermione sticks around or if she sends a flock of birds up your ass," replied Harry sarcastically.

Ron said he would not tell Hermione, but Harry wasn't so sure if he was telling the truth, either way he spent the rest of the night playing Wizard chess with Neville while Ron and Hermione had to patrol the corridors together.
