Chapter 4

"A safe word?" Harry knew what it was from the magazines, but she didn't give the impression she was into that aspect of domination.

"I can't believe I'm doing this." Hermione muttered under her breath before speaking in a much firmer tone. "Yes, a safe word. We'll be playing a role, so we'll need a word or phrase that will allow us to let each other know if things get too far or too weird."

It made sense to him. But then, she always made sense to him. "Okay...how 'bout...Draco on a popsicle?"

Hermione rolled her eyes, "I don't want to be screaming Malfoy's name in the middle of...well...whatever we might do."

"Right, of course. Okay, how about...twat waffle? That was a good one by the way."

She shook her head. "No, it has to be something we wouldn't say normally, and I can't guarantee I won't say that."

Harry's brow furrowed. "What in the world could we possibly be doing that would make you scream 'twat waffle' at me? Wait, no...don't answer that. I'm not sure I wanna know."

Hermione stood there for a few moments thinking. "Okay, how about... Nymphadora?"

Harry smiled. "She'll kill us if she ever finds out, but it's perfect. We've already trained ourselves not to say it in normal conversation. Absolutely brilliant, Love!"

"Nymphadora it is then." She took a deep shuddering breath and closed her eyes, as if she were preparing to jump off a cliff or something.

"Okay, so what do..."

"Quiet! I'm trying to think." She opened her eyes and glared, but faltered a bit when she saw that she startled him. After a few moments, she placed her hands on each side of his face and looked directly into his eyes. "I'm not ever going to hurt you, Harry, you know that right?"

He smiled back at her. "Of course I do. It's just that this is a whole new side of you that I've never seen before. I'm excited, but at the same time, I have no idea what to expect."

She looked into his eyes again for a moment as if searching for something that wasn't there before. "That's one of things that I think I'm really going to enjoy about this. You'll be the first person ever to experience the 'Inner Hermione'. The parts of myself that I've never shown anyone before."

"I'm honored that you're willing to share it with me."

With a small smile, she released his face and stepped back, giving him a long, critical look. "Okay, let's see what I've got to work with here. Ginny's recollections seem to be a bit embellished upon, and I want to know if there's any truth to it, so... stand up and take your clothes off."

Harry hesitated for a moment before Hermione lifted one of her eyebrows at his moment of reluctance. He couldn't believe that this was actually going to happen, but he willed his controllable member to stay in it's flaccid state as he proceeded to remove his shirt and pants. When it came time for his boxers, he bent over and slowly let them pool around his ankles before slowly straightening up.

Hermione gasped at the sight in front of her. Never before had she imagined that a dick could get so big. And never before had she imagined that Harry could have such a beautiful body. After a few moments of staring, her brain finally caught up to her mouth. "Are you using any spells right now?"

"Not technically."

"What do you mean?"

"I made a mistake the first time with Ginny. I forgot to key in the cancellation spell with my physical changes and ended up making them permanent. I found another way to cancel them, but decided I liked things the way they turned out."

"I can see why. You did a good job on the muscles. Not big enough to see any noticeable change with your clothes on, but very nice in an intimate setting. How, um...big... were you before?"

"About half this size."

Hermione's eyebrows rose in surprise. "I'm no expert mind you, but that doesn't exactly seem too bad from what I know. Why keep it this big? Ginny wasn't exactly detailed in her explanation of how things...fit, but you do seem a little...on the large side." She inwardly wondered how much pain would come with the pleasure of having him inside her.

Harry smirked. "There's a spell I can use that'll increase the size of whichever body part I choose on my partner."

"Oh."

"As long as she wants me too, of course." Harry could see the wheels turning in his best friends' head as he answered. He had the urge to ask her about it, but remember that he wasn't allowed to ask any questions without her permission.

After a few moments of self-deliberation, Hermione stood up straighter and lifted her nose slightly as if standing up for herself. "Okay then. Make my tits bigger."

"Are you sure? You're actually not that ba-"

"I said make them bigger, Harry, now!"

Harry quickly raised his hand in her direction and concentrated. A few seconds later, her chest grew from a respectable C cup to a full D, stretching her shirt tighter than it ever did before.

Hermione looked down at her enlarged boobs and marveled at how much more they swayed and jiggled than before. "I've always wondered what it would feel like to be this big. The other girls always got all the attention just because their tits were bigger than mine."

Harry struggled to keep his member from jumping to attention as his best friend of five years began to squeeze and fondle herself. When she noticed him watching, she increased her enthusiasm as she took a few steps forward.

"Like what you see, Harry?"

"Of course, My Love." He nodded as he responded.

"Would you like to see them bigger? Be honest now."

"Y-yes."

As she took a couple more steps so that there were only a few inches of space between them, she leaned over and kissed the top of each of her breasts before looking into his eyes again. "I want to try something then, and then we can see where it leads us. Okay?"

"Okay."

"Do you think you can make my whole body bigger? Not just one part at a time?"

Harry's eyes widened. "T-there wasn't anything in the book that said otherwise."

She leaned over and placed a soft kiss on his lips before saying, in a sultry voice that he'd never imagined could come from her mouth, "make me bigger then, Harry."

"H-how big?" He couldn't help himself any longer. His dick slowly rose to a thickness and hardness he'd never felt before. Never had he imagined that his best friend could turn him on so much.

"How about you start, and I'll tell you when to stop." She looked down at his rock-hard cock and smirked. "My, my, aren't we a growing boy?"

Harry waved his hand at her again and concentrated on what he wanted done. When he opened his eyes to see if he was successful, he took in the most erotic sight he had ever seen in his life. Second by second, Hermione's body grew centimeter by centimeter. Expanding in all directions as her head slowly rose above his hairline. Her breasts nearly brushed against his face as she grew taller and they grew bigger. He was lost in hormonal bliss at seeing something he never imagined possible before, and it was a few seconds before he even recognized that a voice was speaking to him.

"Harry, stop!"

Harry blinked twice and then jumped backward. "Shit, sorry!" He cancelled the spell and stood back as he craned his neck up to see his best friend bending at the neck so that her head wouldn't hit the four-meter ceiling. "Holy fuck." He scanned her body from head to toe, realizing that her now-uncovered pussy was staring right back at him at a little above eye-level.

"Oh, Merlin, this feels so good, Harry. Being so big. I feel so powerful...like I can do anything in the world I want to."

Harry was speechless as she knelt down to the floor; her head still about half a meter taller than his.

She leaned over so that her oversized, yet beautiful face was level with his. "I am so turned on right now, you wouldn't even believe."

"Oh, I think I can believe."

Hermione looked down at his throbbing cock for a moment and gave him a predatory smirk. "Let's see how well your little prick stands up to my giant pussy then, shall we?"

"Bloody hell, I thought you'd never ask."

"Lay down, then, lover boy. You might want to cushion the floor first, though. I'm really not in the mood to crush anyone today."

Harry did as she asked and laid his back on the mattress-soft wooden floor. His member stood hard and proud, perpendicular to his horizontal position as he marveled at how he'd found himself in this situation. Hermione, for her part, crawled over the top of him, straddling his normal sized legs with her tree-trunk sized ones, enjoying the powerful feeling that came with being so much bigger than her best friend.

"Let's see if this sex thing is all it's cracked up to be. Don't disappoint me, Harry."

"I'll do my best." Inwardly, Harry was smirking at her last command. It left open a few doors for him if he ended up not being big enough for her engorged love canal. Thankfully, it turned out he had no cause for concern as she slowly, but surely, lowered herself onto his flagpole. She was large, that was obvious enough, but she was also a virgin, and therefore, still tight enough for him to cause a little discomfort as she worked her way down toward breaking her cherry. As soon as he found himself inside her all the way, she paused for a few moments to catch her breath as he goggled at how her huge boobs heaved and jiggled with each inhalation.

It was a strange sensation, to be sure, having someone so large sitting atop him, with her pubic hairs tickling his stomach around his navel and her huge ass almost sitting past mid-thigh, but the pleasure he saw on her enlarged face sent any further strangeness he might have felt to a metaphorical corner with a proverbial dunce cap on. As she began to move up an down at an increased rhythm, all doubts fled his mind as he concentrated on seeing if he could put her in an orgasmic coma like he had with Ginny their first time together.

"Oh - Merlin - yes - Harry - I never - imagined - this - would - feel -so - good." With each word she sunk herself onto his cock, taking a breath between each thrust.

For a good twenty minutes, she rode him, having orgasmic tremors every few minutes, calling his name breathlessly each and every time, but it was getting to the point where Harry wasn't sure if he could take it anymore. Not only was he getting physically tired, but he was also starting to feel the downside of having someone so big repeatedly sitting on you for an extended period of time.

It was time to take things to the next level.

He had to make his changes subtle enough to where she didn't suspect anything. True, he had her inadvertent command to not disappoint her in the bank, but he still wanted her to feel in control of everything. The fact that one of her fantasies was to become bigger than anyone else make it clear that she was turned on be being in command of the situation, and he had no intention of taking that away from her...at least until he send her over the climactic edge, that is.

Slowly but surely, he increased the rigidness of his cock, while at the same time, enlarging the veins that covered his rock-hard boner. The increased friction was almost instantly noticeable as Hermione began to squeeze herself around him to increase the sensation. As her muscles pulsed around him, he slowly increased the sensitivity of her inner walls and clit as he built up his own muscle strength so that he could withstand her increasingly frenzied ministrations.

"Oh...Maeve, Harry...YES! MORE! HARDER!"

Harry firmly believed that he'd be dead right now if it weren't for the industrial strength cushioning charm he put on the floor. Luckily that wasn't a problem as he ramped up her sensitivity another two levels.

"OH...Ahhh...AHHHHH...OH Merlin! OHHHHH...ohhhhh...YEEEEESSSS!"

At that moment, Harry let it all loose. Her sensitivity doubled, his thickness doubled, his length increased so that he was just big enough to 'bottom out'. As Hermione bent over in ecstasy, he reached up and grabbed her strawberry-sized nipples and twisted. His cock began to vibrate of it's own accord, driving his best friend to orgasmic convulsions.

Harry watched as she sat up out of his reach and spread her arms wide, knocking dishes and pans off the counters in the process. Her hands pressed against the walls, breaking the aged wood outward as her super-sized strength went out of control. She screamed his name at the top of her enlarged lungs and threw her head back, crashing it into the light fixture and sending a spray of glass across the room. But she didn't seem to notice as she quickly bent back forward in order to look down between her massive, jiggling tits. The look in her eyes was something that Harry didn't think he would ever forget in this lifetime or the next. If he were to cast a Patronus right now, he wasn't sure it wouldn't blind anyone that was unfortunate enough to look upon it. Her pupils were dilated to the point where he couldn't see a single speck of her usual hazel color. Her upper lip was raised as if she were about to growl at him. Her chest heaved up and down almost uncontrollably and for an instant, he thought she might bend over and bite his head off like some kind of wild animal. Her next words, however, drove those thoughts quickly away.

"I didn't give you permission to do that, Harry."

Harry smirked, knowing he had an ace in the hole. "I beg to differ, My Love."

She raised her eyebrow at his apparent defiance. "Not that I'm complaining, mind you, but I wasn't quite ready to finish yet."

"Then I beg for your forgiveness, My Love. The one mistake I made was in ending things sooner than you wished. But I felt I had a good reason at the time."

"And what reason is that?" She leaned over him with a playful, but menacing glare in her eyes.

"My apologies, My Love, but I don't think my body could have withstood your...enthusiasm...much longer. So I decided to up the ante a bit."

The predatory look in her eyes vanished. "Oh." She sat back up and Harry could tell her subconscious self was beginning to return. "Oh my..."

"Hermione!" The firmness in her voice broke her train of thought. When he had her attention, he reached up and ran a gentle hand over the area under her navel. "If I thought I was in any serious danger I would have used the safe word, believe me."

"But you said I was hurting you!"

"No, I said I didn't think I'd last much longer. You wouldn't have broken anything, but I wasn't really in the mood to be walking funny for the next few days, so I ramped things up a bit to get things moving along. You were in a world all your own for a while there and I didn't think I had the stamina to go that much longer doing something so physically demanding. I'm not exactly as experienced as my bravado implies."

After thinking about it a few moments, and then showing a bit of relief on her face, she folded her arms across her considerable chest and looked down at him with a critical eye. "You still did something at the end there that I didn't ask for, though."

"Actually, I was well within the boundaries you set for me if you think about it for a moment."

Harry smiled as she took on that scrunched up look that showed she was trying to figure something out. It was still just as adorable at twice the size.

When he saw that she finally figured out, he smirked as she rolled her eyes and shook her head, "'don't disappoint me, Harry.'"

"Exactly."

"Well, you hit that command right on the head in any case. I'm sure-as-hell not disappointed in the least."

"I've noticed. And so has the kitchen."

His best friend looked around the room at the destruction she'd caused. "Wow."

"That had to be the most erotic thing I've ever seen or imagined in my life, Hermione. I never would have guessed you had it in you."

"And what a way to lose my virginity, too. You never do things halfway, do you, Harry?"

Harry smiled. "Not if I can help it."

Just then, a look of horror crossed Hermione's oversized face.

"What? What's wrong?"

"Tonks."

Harry had assumed their little role-playing game had ended at this point, so it was with a confused look on his face that he responded to his giantess friend, "I thought our safe word was Nymphadora?"

But instead of Hermione answering, another voice spoke up from the entranceway behind him. "And I thought I was clear when I said I didn't want anyone using that name?"

Harry closed his eyes, trying his best to will himself into believing this was some kind of nightmare, but it was to no avail.

"Well, well, well. What do we have here? I must say, when I found out it was my turn to check on you two, I gave it only the slightest possibility that I might find you two snogging on the sitting room couch with your hands all over each other. But instead, what do I hear when I walk in through the front door? 'HARREEE! OH! OH MERLIN! OH!'" She mimicked Hermione's voice almost perfectly, which made the whole situation even more embarrassing for the still-naked teens. "Imagine my surprise when I decide to take a peak through the kitchen door only to find an oversized, big-titted Hermione Granger, riding a horse-cocked, not to mention ripped, Boy-Who-Lived like a cowboy rides a bucking-mad bronco."

Not able to stand it any longer, Harry waved his hand upward, cancelling every charm he'd placed on the two of them before he and Hermione had started. His best friend shrunk down to normal size as their bodies returned to where they were when they woke up that morning. They both immediately scrambled for their clothes.

"Aw, don't cover up on my account. And that was some fancy wandless work, Harry. Mind letting a girl in on your secrets?"

"Um..."

Not knowing what to say, Harry and Hermione took the time to get fully dressed again. At the same time they were visibly flushed with embarrassment and still looking as if they'd just been shagged rotten, which just so happened to be true in this case.

Tonks, for her part, began to giggle and laugh uncontrollably. "Holy Merlin, you two should see your faces right now. If only I had a camera."

Hermione was quickly turning from embarrassed, to ashamed, to genuinely upset, as the young Auror laughed her head off. Harry, seeing his best friends' plight decided to take action.

"And imagine if it was Moody that walked in! Bloody hell that would have been pri-IIIEEEEEEEEAAAHHH!" Tonks squealed at such a high pitch that the teens had to cover their ears. When the metamorph subsequently feinted to the ground unconscious, the sound died off and they were left with only a slight ringing in their eardrums.

Hermione rushed over to check the older woman, but was kept away by Harry. "Don't worry, she's fine."

"What did you do?"

"I gave her the mother of all orgasms. Although I'm not sure if I'll ever put that much power into a spell like that again, she looked a bit insane there for a second at the end."

"Oh…Yeah, that's probably for the best."

Harry stopped to think for a moment. "I wonder..."

"What is it?"

"Do you think I'd be able to kill anyone with an orgasm?"

"Why would you want to do that?"

"Bellatrix LeStrange, or maybe Narcissa Malfoy."

Hermione took a moment to think about it. "Well if you couldn't kill them, you could sure-as-hell take them out of a fight. Though I'm not sure I'd want to see what either of their O-faces looked like."

"Maybe I could enlarge their boobs so big they wouldn't be able to move."

"Something to ponder for the future I'm sure. How long do you think we should leave the cackling cunt on the floor?"

Harry snort-laughed. "Cackling cunt?"

"I like her, but she was getting just a little too much pleasure out of our embarrassment."

"She probably has no idea it was your first time. And I'm not exactly fond of being laughed at so much either."

"I suppose we can't just leave her on the floor like that?"

Harry nodded in agreement before casting a wandless Enervate.

It took a few moments for her to gather her wits, but when Tonks finally sat up against the cupboards she looked up at the two teens properly chastised. "I guess I went a little too far, didn't I?"

"Just a little." Harry responded.

At the sound of his voice, Tonks shivered uncontrollably as her body tensed. Harry and Hermione shared a puzzled glance at her reaction.

"Are you o-?"

"Stop talking, Harry! Please!" Tonks covered her ears until she was sure Harry wouldn't speak anymore. "I don't know what you're doing, but your voice is, ah...causing me to, uh...lose control."

"Lose control how?" Hermione interjected.

With a pointed glare and a head nod toward the area between her legs, Hermione got the clue.

"Oh...Oh!"

Tonks looked over to Harry. "Can you stop whatever it is that's causing this? I really am sorry or what I did earlier."

"But I'm not doing-"

"Holy fuck, Harry, stop talking!"

"It must be a side affect of that orgasm spell you gave her." Hermione surmised.

Tonks looked back at Harry. "You...gave me a...?"

"An orgas-"

"Merlin's BALLS, Harry! Will you shut the FUCK UP!" Another visible shiver passed over her body.

Harry held up his hands in surrender and backed away.

"Maybe you should check your...uh...information to see what might've happened?" Hermione asked, not wanting to give away where Harry got his newfound spell-knowledge."

"Good idea."

"For ALL that is GOOD in this world, Harry! Keep your goddamn pie hole shut!" Tonks spoke though her clenched teeth.

Deciding to have a little fun as he made his way out, Harry turned around after walking past the Auror and leaned down close to her ear, speaking in as deep a voice as he could muster, "anything for you, baby."

Tonks squealed in ecstasy once more before immediately turning to take a swing at him. Harry jumped out of the way and laughed as he bolted out the door, giving her a mini tremor with each overemphasized 'ha' along the way.
