Tuesday
It all started one ordinary day in their eighth year at Hogwarts. The war was over, Voldemort was gone, and they were finally getting a chance to be the carefree students they were meant to be. Laughing and talking over lunch in the Great Hall, Harry, Ron, and Hermione enjoying swapping stories of their accidental magic as children.
Of course, Harry Potter could never be permitted to have a normal life, so fate took that moment to intervene, causing a brief lull in conversations across the hall as he interjected with what he thought was just another bit of amusing accidental magic.
“...the time I regrew my hair!”
Pandemonium erupted in the hall. People fell backwards off their seats, those of weak constitutions fainted dead away, and several girls and Malfoy let out high-pitched shrieks of surprise.
“...What?”
Hermione leaned forward across the table, eyes wide. “Harry, hair is completely and utterly impossible to create with magic. Gold, metal, animals, all those are fine, but hair? It’s simply not possible!”
Of course it’s not, Harry thought resignedly to himself.
In short order, it was determined that Harry was a Metamorphmagus. His parents had put a binding on his capabilities as a baby, wanting to keep any potential powers Voldemort might not have known as secret as possible, and only childhood distress and the power of accidental magic had allowed him to use his capabilities in that one instance. The binding was promptly removed, causing Harry’s hair to fluctuate uncontrollably in colour in accordance with the slightest changes in his moods, and the only other living Metamorph in the world was contacted so that she might teach him.
Tonks Lupin, who had taken the opportunity of getting married to change her name, had only narrowly survived the Battle of Hogwarts, but survive she had, and after recovering from her injuries, she’d divided her time between helping with the reconstruction of the Ministry and raising her son, Teddy. The moment she found out that there was another Metamorph in existence and in need of training, she requested a leave of absence from the Ministry and promised to start teaching him that very day.

Tuesday Evening
Harry stumbled into the Head Boy’s suite, exhausted, after a long day of classes and learning. He wasn’t excused from his normal classes, so his Metamorphmagus training was taking place in the hours after dinner, and they were a lot of work on top of everything else.
Unsurprisingly, Hermione was waiting for him, seated in her usual position on the couch by the fire. Technically, she had her own suite as Head Girl, but it was an open secret that she and Harry had been sharing a bed regularly the entire year. They had grown closer and closer during the horcrux hunt, and they had taken one another’s virginities the night after the Battle of Hogwarts, taking comfort and solace in the fact that they were both still very much alive.
She looked up at him with a smile as he came in and patted a spot on the couch next to her. “How was your first lesson, Harry? It looks like you have your hair under control, at least.”
Sitting down next to her and leaning into her, he just relaxed for a minute or two before he responded. “Yeah, we spent most of the time today just going over control. We can’t move on to actual intentional changes until I can keep a single, stable form, and while my subconscious apparently handles most of the major stuff, organs and whatnot, more ephemeral things like hair are temperamental at best.”
“Well then,” she replied, slipping a bookmark in to mark her place and setting her book aside, “we’ll just have to test your control, won’t we?” With a sultry look, she swung a leg over onto his lap and planted a kiss on him.
They made it to bed a while later, and made it to sleep later still.

Wednesday Evening
It was near ten in the evening when someone knocked on the door to the suite. Hermione frowned over at the door and stood, setting aside her book as she headed over. Who would be knocking at that hour?
When she opened the door and saw who was on the other side, however, she cocked an eyebrow at the person standing there, folded her arms, and asked, "Can I help you?"
In the hallway in front of her stood a mirror image of herself, wearing what were blatantly Harry's school robes and uniform, a few sizes too large on him at the moment, and twirling one lock of his mass of curly brown hair around his finger.
"Hi there," he said, his voice over-the-top breathy and seductive, "is Harry in? I was hoping we might discuss some... classwork."
Hermione couldn't help but roll her eyes at him. "I'm afraid not," she replied, playing along but not concealing the amusement in her voice. "He'll probably be back fairly shortly, though."
"Oh." He made a show of being disappointed, looking down at the floor and nibbling on his lip. "I don't suppose I could... wait for him?"
"Sure, come on in," she responded, waving him in with a theatrical gesture. "You can join me on the couch; I was just doing a bit of reading."
She didn't end up doing any more reading that night. The sight of her own face looking up from between her legs was certainly memorable, though.
***
Thursday Evening
That night, Harry came in even later, and he made a beeline for the bedroom the moment he was in the door.
"Harry? Is everything alright?" asked Hermione, standing up and following after him in concern.
Plainly exhausted, he just flopped himself down on the bed, leaving his feet to dangle off the side so he didn't have to take off his shoes. "'M fine," me mumbled into his pillow. "Just tired 's all."
All she could really do was make sympathetic noises, take off his shoes, and lever his legs properly onto the bed.
***
Late Friday Evening, Technically Saturday Morning
It was a chilly night atop the Astronomy tower, and Hermione bundled her cloak closer around herself as she ascended the steps to the top. Harry hadn't come back to the suite at all that night, and when midnight had come and gone with no sign of him, she'd retrieved the Marauder's Map and tracked him down.
As she reached the top of the stairs, she saw him sitting on a crate out on the open balcony, leaning back and staring up at the stars.
"Harry?" she said softly, slowly approaching him. "Is everything alright?"
Sighing, Harry dropped his chin to his chest and closed his eyes. He didn't respond at first, but just as Hermione opened her mouth to repeat the question, he started to speak.
"I thought it was all fun and games at first, you know. Being able to change your face - it's a laugh, right? Pig snouts around the dinner table and all that. ...Merlin alive, if that was all it is, I'd be a happy man."
Walking up next to him, Hermione tried to get him to scoot over so she could sit down beside him, but he just stood up and walked over to the guardrail, leaning on it and looking out over the Forbidden Forest.
When it didn't look like he was going to elaborate, she asked him, "So what's so awful about it?"
Not looking back at her, he responded, "I have complete control over the form my body takes, Hermione. Some of the things I can do... They're disturbing, or at least they should be."
Hermione frowned to herself. "I don't understand. What do you mean, should be?"
He hung his head. "On Wednesday, we... We covered more than just touch-morphing. We started on independent changes as well, and by the time I was done, I was reasonably able to change the general size and shape of most every part of my body."
"Harry, that's amazing! Why didn't you say anything?"
"I wanted to show you, Hermione. I came back wanting to impress you, maybe make my tongue longer, my... y'know... bigger, that sort of thing. I just... When it came down to it, I had to hold myself back."
"What?! Why- Harry, why would you think you'd ever need to hold back on me?"
"Because I wanted to go too far!" he snapped, spinning around to face her. "I wanted... Gods above, Hermione, I wanted to do so many things, changing and growing and reshaping myself all sorts of different ways, and if I had started I don't think I would have been able to stop! Ever since my abilities were unbound and Tonks has been teaching me how to use them, it's like a part of me that wasn't there before is starting to speak up, and I keep wanting to do things, to use my abilities in a million different ways, and some of them should be downright disturbing! The things Tonks showed me how to do today, I want to..." Grimacing, he ran his hands down his face and turned away again. "Hermione, if you knew the sorts of things I wanted to do with you, I'm fairly sure you'd run screaming the other way."
***
"Oh really."
Blinking at her tone, Harry turned around again, mystified. She was angry at that?
"Hermione, what-"
"Don't you 'Hermione' me, Harry James. How long have you been keeping this bottled up from me? How long have you been convincing yourself I'd turn you away just because you wanted to do something unusual?"
"It's not just 'unusual', Hermione, some of-"
"How long?"
"Since Wednesday or so, that's all!"
Advancing on him with her eyes narrowed, she moved forward into range and jabbed him in the chest with a finger. "Well, you can just take your notions of what I might or might not find disturbing and forget about them. I love you, Harry James Potter, and a few unusual desires in bed isn't going to change that. In point of fact, you're hardly the only one with interests they haven't acted on."
"I- What?"
"Do you remember a little dalliance back in October, taking place in Professor McGonagall's old classroom?"
Blushing, Harry just nodded in response.
"Well, just thinking about our little 'professor/schoolgirl' routine still gets my motor running, and that was months ago. I've been patient with you because I knew you didn't have the most broad of experiences growing up, and I've been working on expanding your horizons bit by bit, but if I find out you've been hiding a kinky side from me this whole time, I'm going to be seriously upset, buster."
Gobsmacked, it took Harry a few moments to collect himself, at which point he shook his head vehemently. "N-no, just since my abilities were unbound."
"Well alright. I guess we just have our current situation to resolve, then, don't we?"
"Resolve how?"
Hermione smirked at him. "Simple. Rather than dancing around the issue and trying to discreetly nudge things forward, we just set up some ground rules and go to town. For example: I'm going to rule out bodily waste of any kind right now. Does that impede any of your allegedly-disturbing urges?"
Harry shook his head.
"See? Just fine. How about you, do you have any rules you want to lay down?"
Flustered, Harry just floundered around for a moment.
Hermione grimaced and jabbed him in the chest again. "Alright, I've got another rule: Wherever this incoherent, idiotic attitude came from, it can pack up and go right back there. You're a smart, capable wizard, Harry, and this feckless behaviour is just getting in our way. You defeated Voldemort, Harry, are you honestly going to let a blunt conversation about our sex life get the better of you?"
Harry opened his mouth to respond, closed it again, then took in a deep breath and let it out. "No. No, you're right, sorry. I just..." Taking another deep breath, he centered himself and then continued. "Okay. Where were we, rules?"
Nodding in satisfaction, she crossed her arms and waited for him to come up with something.
"Right. Well, how about saying 'no blood or injuries'? Is that okay with you?"
"How about 'no significant blood or injuries'? We wouldn't want to have to completely ruin an evening just because someone got overeager with their fingernails, would we?"
***
They went back and forth for another fifteen minutes or so before they'd come up with a solid set of simple, straightforward boundaries, and after coming up with a safeword (Hamlet) and a safe action, just in case one of them wasn't capable of speech but still needed to cut things off (tapping or otherwise making noise in the pattern of "shave and a haircut"), they decided that they were ready to go.
Wrapping her boyfriend up in a big hug, Hermione nestled her face into his neck and murmured, "It's settled, then. No more feeling sorry for yourself, and no more working yourself into a frenzy over something that's not even a problem."
Harry responded to the hug in kind, resting his cheek on the top of his girlfriend's head. "Well, okay, but only because you said so."
"Prat!" Laughing, she pulled away and shoved at him lightly. "Now, are you ready to go back to the suite and show me just what you've learned?"
A predatory grin darkened his face, and he stalked forward towards her. "Oh, I'll show you exactly how much I've learned," he growled, and then he reached down to lift her into his arms, swing her over his shoulders in a fireman's carry, and make for the stairs. She made the obligatory demands that he let her down the whole way back to the suite, but with no safeword forthcoming, he simply refused.
When they finally made it back to their bedroom, Harry tossed her onto her back on their bed and leaned down over her, planting his hands outside and above her shoulders and leaning his face down next to hers. Growling low in her ear, he said, "Are you sure you're ready for this? We could still back out if you wanted."
He wasn't speaking from insecurity this time, though; he was teasing her, and her only response was to arch her back seductively and cock an eyebrow up at him.
He smirked down at her, then straightened up a bit and took a deep breath. "Well, alright then. Here goes." Rolling his shoulders and planting his feet, he steadied himself, then reached down into himself and applied his will - and then his every fiber suddenly tensed, and after a moment, Hermione realized what she was seeing. He was growing, getting physically larger right in front of her.
His every muscle seemed to swell forth, his trim and fit frame quickly packing on mass he couldn't have earned with a decade at the gym. His uniform shirt tightened across his chest as his shoulders pushed outwards, and buttons started snapping off mere moments later. Hermione reached up to help him out of his shirt, but he just grabbed her hands in one of his own - which was growing as well, turning into a big, meaty mitt with fingers the size of sausages - and shook his head with a wicked grin. His growth slowed down for just a moment, then surged forward, and his shirt was shredded at the seams, unveiling thick, burgeoning slabs of muscle that showed no signs of slowing down. His pecs were already inches thick and swelling outwards, and his ribcage was barrelling out, leaving his chest wider and deeper by the minute. He was also growing upwards, his chest gradually moving up and getting more and more distant. His abs were like small bricks in motion, shifting and jostling with every minute adjustment to his position, and she couldn't help herself - she reached up and caressed them, and she couldn't believe just how hard they were, not to mention hot to the touch. His skin was extremely warm, and as she roamed her hands up to grope at his ever-thickening musculature, she found herself wanting to feel as much of that heat as possible.
She wanted to wrap her legs up around his waist, but with his knees on either side of hers, she found that she couldn't - and a glance down at his thighs completely derailed her thoughts as she spotted something she'd completely forgotten about.
Harry's penis was growing now along with the rest of him, and he plainly wasn't holding back on it. As big around as a grapefruit, his massive member reached most of the way down to the bed, and its growth wasn't slowing down in the slightest. As she watched, his (half-flaccid!) cock grew down to the point where its head nudged down against the bed, and it just kept going, pressing its big domed bell-end right into her crotch.
She rolled her hips to brush her nether lips up against his head and reached down down with both hands to grasp it and heft it up between them - and where his chest had been warm, his cock was practically searing, and the moment she touched it, it lurched in her hands and started to surge forth, pumping up both with Harry's ongoing growth and the natural swelling of an erection. Harry moaned as her touch brought him up to full mast, and he thrust forward slightly, moving his hardening ramrod back and forth in her grasp. He started leaking pre as he rocked back and forth atop her, and he soon had her midsection practically coated with the warm, slightly-viscous substance. It ran slowly down her sides, beginning to pool on the sheets under her, and she couldn't help but contribute what she could; her cunt was absolutely dripping wet, and she could feel her own warm lubricant running down her rear to start its own little puddle below.
By the time his growth finally started to taper off, Hermione was staring up at the bottom edge of pectorals half a foot thick, and the length of her whole torso was spanned by just his abdomen. His legs were spread out on either side of her own, his gnarled thighs each without question larger than her whole upper body, and she could only barely make out the tops of his huge calves. His hard-on, which he was grinding down against her with an increasing rhythm, nudged up against the underside of her breasts with each thrust, while his colossal nutsack rested on the bed between her legs, and his member was at least as thick as one of her thighs, its head very nearly as big as her own.
He utterly dwarfed her. Each of his arms, which he'd moved and shifted up the bed as he'd grown to the point where she would have to crane her neck to see them, probably weighed more than her in her entirety.
And as he started to growl deep in his chest and thrust harder and faster against her, she realized that he could only be building up to something truly massive.
She pushed herself up against his rutting, meeting his thrusts with her arched back, and moaned loudly as she felt every vein and ridge of his gargantuan cock rubbing against her abdomen. She had no hope whatsoever of taking that thing inside her, but that wasn't going to stop her from getting off against it. She reached her hands down, running them through the puddle of pre above her navel, and grasped at the top of his cock with one hand and went for her dripping cunt with the other. Slipping two fingers into her sopping twat with ease, she moaned louder as she started to pump furiously in and out, shoving in a third digit when the thought of taking as much up her pussy as she possibly could pushed its way into her brain.
Vigorously, she rubbed her hand back and forth on the upper side of his gigantic erection, sparing no efforts on misguided concerns of gentleness. He was grinding it down against her with a vengeance, so there was no sense being delicate with her measly hand. As she pumped her fingers into herself, she groped at his humungous member, grasping at its thick veins and hard ridges and trying in vain to find some purpose as he moved it back and forth against her. He was just fucking down onto her at this point, his teeth bared and his eyes staring down, unfocused, at some spot on the bed above her head as he just ground his cock against her.
She writhed underneath him as his pace kept picking up, and soon she was building up to her orgasm as his pace started to reach a crescendo. He was violently thrusting back and forth above her, his dick bashing into the undersides of her breasts with every thrust even as it pressed down on her to the point that she couldn't lift herself under it at all - and then he shuddered, and his great balls lurched upwards betwen her legs, and he buried himself home, his cockhead shoving itself up beneath her breasts... and he came.
"FUUUUCCCKKKK!"
The first burst was like a fire hydrant had burst open, his thick, creamy cum launching forth in a torrent several seconds long. His cumfountain practically slammed into her, and her head was knocked back against the mattress by the force of it, her mouth and nose suddenly engulfed, his torrential outburst forcing its way down her throat and halfway up her sinuses. It was only her extreme good fortune that she'd closed her eyes moments before he had unleashed that kept her from experiencing that extremely unpleasant sensation on top of everything else.
Of course, as she struggled to gulp and swallow down as much of his (frankly, delicious) cum as she possibly could, his second burst followed, and she felt momentarily submerged, a veritable river of thick ejaculate pressing against her and flowing past her face.
And just as she found herself struggling not to gasp for air, unable to simultaneously breathe and swallow what she could of his gallons of semen, a tingling of magic brushed over her, and her airways and eyes were suddenly clear. She was still coated, positively drenched, and he was still hosing out buckets of thick, sticky cum every couple of seconds, but he was mostly upright now, kneeling on either side of her on the bed, convulsing slightly with each surge of cum that gushed out over her. Whatever spell he'd cast was keeping her eyes clear and allowing her to breathe - though she wasn't sure how, as her mouth and throat were still filled to the brim with cum - and as he looked down at her, she was struck by the out-of-place gentleness she saw on his face. He looked so utterly fond of her, even as his body spasmed as his cock hosed out yet another wave of cum over her, and his look warmed her inside like nothing else. Arching her back seductively up at him, she reached up to caress her cum-coated breasts, squeezing them together as another burst of cum surged forth, rubbing his thick seed into them like she was soaping herself up in the shower.
Gradually, his ejaculation petered off, and once he was no longer hosing out gallons of semen and instead just spurting out relatively modest dollops, he eased himself down onto the bed beside her. Swallowing her way to a clear throat, she gasped a breath, mostly to make sure that her airway was in fact clear, then smiled over at him and collapsed back fully onto the bed, utterly spent.
