Harry swore loudly as he watched his phoenix-wand fly through the air before being gracefully caught by a smirking witch at the other end of the room. He had spent the last three weeks occasionally dueling Nymphadora Tonks in the room of requirement, her personal playground that she had reluctantly revealed to him.
To call the duels eye opening would have been an understatement, they had seriously made Harry re-evaluate his own skills. Used to being the first of his year and praised by both teachers and students alike, he realized he had let his ego get the best of himself. Whereas he knew from duelling Amelia during the Christmas holidays that he was far from her level, he still thought he could take on Hogwarts students easily. Tonks had rudely disabused him of that notion the first time they fought.
His loud spells were either gracefully evaded or blocked by various silent counters, ranging from impeccable transfigurations to shields that flashed into existence before his spell had even left his wand. The constant barrage of spells that she rained on him was terrifying, the silent casting leaving him desperately trying to identify what to dodge and what to attempt to block.
Dodging behind cover left her free to apply her natural transfiguration capabilities on the room, swarming him with animals made out of stone and soil. Harry realized her dream of becoming an Auror was not farfetched at all as he felt himself being completely outclassed in every possible way.
The original reason she revealed the room to him was their need for privacy, their, or more accurately her, sexual experimentation had increased rapidly after she got over her initial shyness. Harry was not one to complain, the sexual relief was fantastic and just what he needed to get his mind off other things.
It was after they had pleasured each other that she revealed the true purpose of the room, her personal training-ground for the Auror Academy. That had made Harry jokingly suggest she should fight him, thinking it would be an even duel. Hence his rather rude awakening when she had twirled his wand between her fingers ten seconds later, smirking at his dumbfounded expression.
Harry snapped back to the present as she lobbed the wand back to him, catching it easily from the air.
"Man, I really need to learn silent casting, watching you have a shield up before the spell is even halfway is annoying as hell."
"Don't worry about its Harry, it's usually only taught during sixth year DADA classes, in preparation for the NEWTs."
He grumbled at that; he had no intention of waiting five years to get rid of his annoying handicap. Even if these duels were humbling, he was also learning a lot. His awkward exaggerated dodging he had done at the start had quickly been corrected by Tonks, pointing out that smaller moves were almost always better.
Teaching him a basic stance where he presented only his shoulder to his opponent, his body kept sideways to make a small target had helped a lot. Implementing quick small steps to dodge spells instead of the ridiculous rolls and jumps he did earlier had further improved his movement, letting him launch faster counter-attacks and always keep an eye on her.
Glancing over at Tonks he couldn't help letting his eyes roam over her body, dressed in tight fitting exercise clothes that did nothing to hide her figure she was a very distracting sight. A tight sweaty grey tank-top clung to her ample breasts while her firm butt and long toned legs were encased in black leggings that seemed painted on.
Proper purebloods would have a heart attack if they ever saw her wear that. Hearing a small cough, he brought his eyes up to her amused, if slightly exasperated face.
"Improving your magic and having sex, are those the only two things you think about?"
"It's hard to not think about sex in present company."
He punctuated his sentence by looking over her body again, Merlin but she was hot. She flushed slightly, not as much as she had a few weeks ago, having grown used to his open way of talking while in private.
He had tasted her for the first time two weeks ago, her loud moaning making him fear she'd overwhelm his silencing charm. After that her embarrassment seemed to have gradually disappeared and she simply enjoyed their time together to the fullest.
"Later Casanova, you helped me with my accuracy so it's my turn to help you with your parrying."
Harry nodded, composing his mind with Occlumency and readying his wand for the exercise. His talent in the art had blown Tonks completely away, as she had never expected him to be able to do it after seeing his otherwise pitiful dueling ability. Well, pitiful compared to her, exceptional, even prodigious compared to any other first year.
Parrying meant exactly what the name said, you parried a spell with your wand by channeling magic into it and batting the offensive spell away, the direction depending on your skill and power. Reflecting a spell straight back to the caster was obviously harder than simply using a glancing blow to slightly change its direction.
Parrying relied on several things, excellent hand-eye coordination, the ability to regulate the magic you channel and large magical reserves to be able to overwhelm the power of the offensive spell. All were things Harry excelled at, having played with the power of different spells ever since Mistress Narcissa's tutoring.
He had grasped the basics in a matter of minutes, completely stunning Tonks who herself even had issues the art. Amazed she had quickly implemented it into their practice, throwing Tickling Charms at Harry from different angles, adjusting the power and speed of the spells constantly to keep him on his toes.
Taking the now familiar stance he stood sideways with his right shoulder towards Tonks, his wand held ready. The silent barrage started almost instantly and Harry used his Occlumency to remove all distracting thoughts while channeling a steady flow of magic into his wand, making it hum softly in his hand. The usual feeling of power flooded him before he started batting the spells away, making small movements with his feet to dodge any spells he wasn't fast enough to parry.
Tonks watched fascinated as the now familiar glow lit up behind his eyes as he moved, making the smouldering green eyes shine in the room. She couldn't help but be awed by the sheer amount of magic he put out on a regular basis and was having trouble keeping a professional attitude as her groin heated from the familiar sensation of his released power.
It was like a physical presence coating the room, she was certain anyone he wished harm would feel intimidated by it, yet all she felt was a soft caress on her skin, like a lover's tongue dancing over her body. His magic had clearly grown to accept her, changing from the first time she felt it to what it was now. She shuddered softly as he watched him perform the parrying man oeuvres with such ease, something that was taught as an optional additional class during the seventh year, yet here was a first year making a mockery of the entire system.
Harry occluded his mind as stubbornly as he could, yet Tonks's now usual reaction to his magic was incredibly distracting. The pink lips were parted as soft pants could be heard while a red flush covered her neck, disappearing under the tank-top that covered her obviously excited breasts.
Her bosom jiggled softly as she danced around the room, trying to slip spells past his defence. Her unexpected pirouette was all it took, his eyes shifted from her wand to the fantastic arse on display before he felt a spell slip past his wand, making him burst out in chuckles.
"Haha, Merlin, but that's cheating."
She had a wide grin on her flushed face, not looking guilty about her little trick at all, before she grabbed his hand and pulled him towards the shower door that seemed to appear out of the wall.
"Not my fault you're easily distracted."
His muttered "damn hormones" drew a small chuckle from her, yet he couldn't help wondering if he was entirely normal in that aspect.
His sexual drive seemed completely off the charts, his mind and eyes seeming to drift to any attractive female within range, mentally undressing her within seconds.
Watching Tonks peel off her clothes, revealing her gorgeous slightly flushed pale skin as she skipped into the shower made him push those thoughts away. As he removed his own clothes, he realized that right now he couldn't care less.
Slipping in next to her in the shower, he gave her mouth a gentle probing while his fingers played with her soaked folds, she seemed to be more than just excited, her wetness soaking his hand. Moaning into his mouth she leaned against the shower wall before pushing him down to his knees,
"Please Harry; you need to finish what you started with your damn magic."
Chuckling he hooked his arms under her legs; grabbing the pert ass before moving in towards her puffy lips. He enjoyed pleasing Tonks, not only because she always returned the favor afterwards, but because watching her lithe body moan and writhe on his mouth always made him hard as a rock.
"Wait, I want to try something new today, it was in that Kama Sutra book you got from Mrs. Malfoy."
Harry looked up in surprise before she grabbed her wand from shelf and pointed it at him. She obviously didn't care if it got wet, for a good reason, professionally made wands, like those from Ollivander's were protected against such things.
It was a cause for some hum our among purebloods as they watched muggleborns treat their wands exceedingly carefully, like it was going to snap at any time. Like the wizarding world hadn't taken precautions to protect their most valuable possession, what a ridiculous thought.
"Stick your tongue out."
Doing as he was told she did a quick manoeuvre with her wand before softly whispering "Engorgio", her voice tinged with anticipation. Harry's eyes widened as he felt his tongue swell, growing almost twice as thick and three times longer.
His exclamation of surprise came out as a muffled mumble. Tonks stared at the appendage in rapture before placing her hands in his messy locks and moving him towards her pussy. Not one to argue Harry moved in, trying to get a grasp of his new appendage by lapping at her pussy like a dog.
He heard her gasp softly as his flat tongue covered her entire pussy, licking it from her rosebud up to the small patch of vibrant red hair at the top of her slit. Getting used to the new size Harry gently pressed it between her hairless lips, watching as her eyes widened in awe as the giant tongue slowly slipped into her soaked hole. Her shocked voice echoed in the room,
"Oh Merlin!"
He was being overwhelmed by her taste and feel as his tongue sent every sensation back to him, slowly working its way deep into her tight passage. Bottoming out he moved his mouth towards her clit, using the base of his tongue and lips to suck on it while licking her insides, sawing his tongue in and out of the juicy hole.
She was gasping and moaning around him, most of her weight already resting on his shoulders as his hands supported her tight bottom. His tongue seemed stronger and more flexible because of the new size, letting him relentlessly probe and explore around her while her pulsating vaginal muscles tried to desperately grab the slick intruder.
Her hands were grabbing his hair almost painfully as she tried to ride his mouth, panting loudly while bucking her hips. Harry loved the way her taste flooded his mouth as she softly moaned out his name, repeating it over and over again as her legs started shaking.
Sucking on her clit he started flexing the tongue, making it bend around inside her, driving her over the edge as she shuddered against his face. Harry admired the way her toned body tensed as she came, her abs clearly visible against her taut stomach while her perky tits swayed above his eyes.
Her hands cradled his head as he kept the motion up, making her ride out her orgasm to the fullest while her loud shouts filled the fogged bathroom, flooding his mouth with her musky taste.
Finally with a last gasp of breath she went slack, signaling Harry to let her down. He slowly removed his tongue while easing her down on the shower floor, feeling proud at how utterly wasted she seemed.
It took a minute of her simply panting before her eyes focused on his smirking face and she realized she still hadn't fixed his tongue. Fumbling lazily after her wand she reversed the transfiguration with a small flick.
"Finally, can't seem to talk at all when it's like that."
She had a satisfied smile on her face as she looked at him,
"That's, pant, fine, you more than, pant, make up for it in other ways."
He laughed as he slowly stood up, bringing his raging erection to her eye level. She slowly licked her lips as she stared at swinging cock dancing right in front of her face.
"Subtle, you are not."
He chuckled while slipping his hands into her dark, almost brownish red hair, a color he now recognized as her being sexually satisfied and very relaxed.
"Can't help it, I'm a hormonal teenager and that was probably one of the sexiest things I have ever seen."
She smiled as she grabbed his shaft, pumping softly while using her left hand to gently play with his testicles.
"Since you tried something new on me, it's only fair I return the favor."
He gave her a quizzical look before softly gasping as her soft lips wrapped around the tip, her tongue gently teasing the sensitive skin. Wrapping his hands around her head he enjoyed the soft pumping motion before he felt his cock hit the back of her mouth, making him ease up on the pressure.
She kept pumping it while adding saliva though, making small slurping sounds echo in the room as his slick erection pushed against her throat repeatedly. To his surprise he felt something shift around his cock before she pushed it in again, making it slowly glide down her incredibly tight wet throat.
He moaned as he felt his entire shaft disappear between the pink lips, her nose coming to rest against his pubic bone. Looking down he gasped at the sensation, watching himself completely disappear between her now triumphantly smirking lips. Then her throat muscles got to work, wildly swallowing and spasming around his cock, almost bringing him to his knees right there.
"Oh Merlin, that's incredible."
Her eyes seemed to smile at that, before pulling back until he slipped out of her throat, only to push herself back to his skin again, making him moan softly at the sensation of slipping into the velvet vice again.
Harry was quickly understanding the additional advantages of being a metamorph as he tangled his hands in her dark red hair, softly fucking her sexy lips, watching in awe as the wet tight mouth sucked him down to the hilt over and over again.
Feeling two wet fingers play with his rosebud, gently pressuring the wrinkled skin, he looked at her in surprise, only to see a mischievous glint in her eyes. He gasped as they slipped in; making her smile even wider, she had managed to worm out of him that he quite liked having his prostate played with.
What she referred to as a discussion was something Harry would have called an interrogation on 'what he had done with Mrs. Malfoy', but it was too late for that now.
The assault from two sides was making Harry feel lightheaded, the two fingers, if unexperienced compared to Mistress Narcissa's, knew enough based on the Kama Sutra book to achieve their goal.
The pleasure shot through his body straight to his groin, barely giving him time to moan out a warning before he started unleashing his load down her throat. Instead of backing off her reaction to his warning was to take him deep into her throat again, while starting to softly hum and swallow around his twitching cock.
The additional vibrations were driving him insane, making him desperately squeeze her face into his crotch while he felt himself shoot down her throat repeatedly. His anus was clenching around the pumping fingers desperately, as if trying to grab them, yet they showed no signs of slowing down either, milking him dry as the greedy mouth sucked out every last drop.
When he finally felt the orgasm abate his legs were trembling, making him kneel down in front of the amazing young woman who had just driven him half insane. She followed his cock down to the floor before finally backing off, releasing him with a wet slurp and taking small panting breaths as she swallowed what was in her mouth.
Harry just stared at her wide eyed, trying to understand what happened to the shy girl from a month ago. She smirked at him victoriously,
"I take it you liked that?"
He simply leaned in and kissed her lips softly, not caring if he tasted some of himself while doing it.
"That was amazing Tonks, thank you."
That finally got a small blush from her, yet it seemed to pride more than anything, confusing Harry even further.
"I take it you've been studying the book then?"
She smiled happily now,
"Yeah, it's amazing, it has so many ideas on what we can try!"
Harry thought about arguing against that before almost slapping himself. If a girl looking like that wanted to explore the entire Magical Kama Sutra with him, he wasn't going to argue, wasn't he supposed to be learning to keep his mouth shut? This seemed like a good place to start.
After catching his breath, he just nodded at her happily, before grabbing her shoulders gently and turning her around. Grabbing what he now knew as her favorite shampoo he started massaging it into her locks, his fingers playing with her scalp making her almost purr in satisfaction.
"Not that I'm arguing, quite the opposite, but what brought this on Tonks?"
He paused for a bit before continuing,
"I mean, you weren't exactly this adventurous a month ago."
She leaned into his massaging hands like a cat being petted before her soft voice replied,
"I don't know. I mean, I guess I've always wanted to try a lot of things but whenever I'd get close to any boy, they would brag to everyone how they 'bagged the metamorph'. I had barely gotten past the first kiss and they'd ask me if I could change things for them."
Harry hummed softly, starting to add some magic into his hands, feeling like she could use some comforting.
"With you though I know you won't be bragging; I know you're a good person who respects me for who I am. I guess it's a bit silly but I find more comfort in you than in any older students. I guess I'm just finding out about a completely new side of myself."
She moaned softly at the sensations his hands were causing before laughing,
"The fact that you can do what you're doing right now doesn't hurt either."
He laughed out loud at that, thinking about how much he actually owed Mistress Narcissa for teaching him to regulate his magic. Thinking about her brought up mixed feelings, he knew she was unhappy in her marriage and he really liked her, maybe even more than just liked.
Still, she had another side to her, one he had barely started to glimpse, one that enjoyed control and power to a point where she would lose track of what she was doing. He knew that intimately.
"Your turn."
He was snapped out of his thoughts as Tonks grabbed the bottle of shampoo and motioned for him to turn around. Leaning into her hands he decided Mistress Narcissa was a problem he'd deal with some other time, there was only a month of school left and he planned to get through as much of the Kama Sutra as Tonks could possibly want to. Grinning he realized he had actually been annoyed at Mistress Narcissa for giving him the book for Christmas, how dumb was that.
