Chapter 15 - The Full Moon

"Harry!"

In the common room, an emerald eyed boy looked up from his book on magical maturity. A frown crossed his lips as he was halfway through the relatively thick book. However a smile soon broke out as he looked who was calling him in a loud whisper.

"Hello Katie, how have you been?"

"Harry, it is nearly time to visit Madam Pomfrey, remember." The dirty blonde chaser answered as she pointed to the clock.

"Why does he need to visit her? Haven't he been there quite a few times already." Hermione, Harry's brown bushy hair friend asked. However, you could hear the concern in her voice.

"Maybe it's my charming personality?" Harry joked as he got up.

"Honestly Harry, this could be serious and I am worried about you." Hermione said, gaining a slight edge to her voice. She was already on edge from his challenge to prove Lockhart is not a fraud.

He could only shake his head as he waved it off, "I'm fine Hermione. She probably wants to make sure I don't relapse or something. So I will see you tomorrow."

Hermione's eyes narrowed but could only nod as she knew Harry would tell her in time. It will however not stop her from attempting to find out on her own. She had thought she had solved him pretty well last year but over summer a large change took place. A change she was unsure what to do about and wanted to solve.

Before Harry left for summer, he was down, shy and not enjoying his fame. Now however as far as she could tell, he was more confident and shrugged off fame as if he had years of practice. Which shouldn't be possible due to only learning about it the year before. Then it was his knowledge and other aspects that didn't add up making her wonder if he was an imposter.

"Well, Katie let's be off." Harry smiled as he smiled at the two witches eye roll.

In the Hospital wing, Madam Pomfrey was waiting for them with Dumbledore who smiled as they walked in. Katie who really only saw the Headmaster at meals or the occasional stroll through the school was at a loss. Her mind wandered if he was there to tell her she was expelled.

"Headmaster, what can I do for you?" Her voice cracked trying to hide her nervousness.

She could only hear chuckling and laughter from both males as the school healer just rolled her eyes. The reaction sort of unsettled her as she felt Harry's arms wrap around her shoulders.

"Katie, there isn't anything to worry about." Harry's voice echoed in her ears.

"Indeed Miss Bell. I just came by to tell you as long as you don't go telling everyone and don't infect them. We won't have a problem." Dumbledore answered, receiving a rapid head nod. "Then I am sure we can overlook your monthly run in the woods if you will. Now in the morning return here and a house elf will have clothes for you."

"Now, I will inform your teacher that you are excused from your morning classes. Let's say a prank went wrong and you will be released after lunch." Dumbledore stroked his beard.

"Why not just say we tripped on the stairs on the way here since Katie said Madam Pomfrey wanted to see us. The fall was a bit nasty fracturing my arm and her leg." Harry said instead before a sparkle appeared in his eye. "Neither I nor Katie are known pranksters so the excuse wouldn't really stand. Though, I guess I can form the next generation of Marauders."

"Minerva is going to retire." Pomfrey sighed. "If that group reforms and with the Weasley Twins."

"What are the Marauders? I think I heard the Twins mention it once or twice before." Katie asked.

"They were a group of students who were known pranksters. While they gave laughs some of their jokes went a bit far." Harry said with a sigh and slightly growled as he continued. "Now one dead, one is drifting without aim, the third is framed by the fourth and in Azkaban and the last is in hiding."

"Oh." was Katie could say but decided not to push it as anger soared inside Harry and with the full moon mere hours away. She decided to wait as she will be told in time as there more to this if Harry knew this much.

"Well, I supposed we should be off. We will see you tomorrow."

--

Deep inside the Forbidden Forest, small twigs snapped below Harry's feet as he wore worn out clothes. Behind him, Katie followed closely in loose clothes trembling slightly as her nerves about what to come. The nightly breeze and the odd roar in the distant certainly fill her with confidence.

"Will it hurt?" Katie finally asked breaking the silence that fell between them for the last hour.

Harry's thoughts shot back to his transformation. "Yes and I hope you didn't ingress any potions in the last few days."

A bright blush filled her cheeks, "Only for cramps and the potions to prevent pregnancy. I am too young to have a child. Most witches' bio clock is synced around the full moon. Wait why am I telling you this?"

"Well, it wasn't that long ago girls would have or soon have children at our age. However, I am not sure if your wolf side will reject these potions or not." Harry hummed as a grin formed as her blush deepened. "I believe you will be fine but if not we know about it next time."

It was long after this that the clouds above moved allowing the rays of the full moon to fall upon them. Instantly Harry felt the familiar feeling as his body heated up, but while it had some discomfort that was it. He also focused on how his body felt when it transformed in hopes to find out how to transform later on like an animagus.

From Katies screams of agony her transformation wasn't as nice due to it being the first time.

If it was anything like his, her bones were snapping and being rebuilt as her muscles tore themselves apart. Since she was throwing up he would assume that the potions she mentioned were fine. Her clothes on the other hand were the opposite as she tore at her top and loose shorts.

As her fingers turned to claws, long claw-like tore into her shirt. As her left hand clawed down from her right breast to her hip. Harry could see her right tan nipple as dark brown almost black fur sprouted from her body. Her shorts had a similar incident as her knickers could be seen before the final stretch of the transformation.

There a wolf slightly larger than a puppy appeared where Katie once stood. Harry not far behind in his transformation was soon at eye level with her. He assumed it was because he was still growing and alpha he could match her. However, he didn't expect her to growl at him in an attempt to establish dominance.

Growling, Harry soon found his instincts kicking in and tackled her below him growling. As she snapped and tried to bite him, he retaliated and soon had her submitting below him. Once the hierarchy was established, Harry found himself nuzzling her as he rubbed himself against her.

She lifted her rear as she yelped ready to play with her alpha. Following her lead, Harry found himself rough housing with her as they explored the forest. From the slight run in with the Centaurs who wisely allowed them to pass, to running with the Thestrals and Unicorns. Even if he had to fight his instincts and Katie from attacking.

By the end of the night much to his displeasure and hope of not returning to it. They ended up on the edge of the Acromantulas territory killing some of the smaller ones that attacked. Well calling a five foot tall spider small was a stretch in his opinion. Harry was just hoping Hagrid doesn't get in trouble because of them.

--

The next morning, Harry woke up next to Katie in a small pile of leaves. While his clothes were in better condition, Katie's were basically in rags. Not surprising since he watched her tear them apart. However, at least she kept most of her modesty besides one breast mostly uncovered from the tears.

Harry studied her new body and saw her body was slightly more toned than the night. He noticed her looks were slightly sharpened and enhanced making him wonder if she was part veela. Well that might be stretching it for the time being, since there wasn't an allure but he could smell her arousal.

It would seem she was having a nice dream which he wouldn't mind fulfilling, but they lacked the time. If her moaning and thighs rubbing was anything to go on.

"Katie, wake up. We got to head back to the castle." Harry gently nudged her as she let out a soft moan as her eyes opened.

"Can that wait." She complained. "I want you, now."

It was an hour later, before they headed towards the castle covered in dirt and leaves. With Madam Pomfrey ranting on about the pros and cons of the mistress/wife bond the two formed.
