"The moon is limned in fog tonight," Firenze said without preamble as I came up to him. As usual, he was staring up at the sky rather than at me. As usual, Petty and Mafalda let go of my hands and took their seats nearby to watch and listen.

Lacey had come with us once, being fascinated by the idea as well as wanting to see the centaur again (having made his acquaintance at my housewarming party in the summer), but it was difficult for her to sit still without commenting or asking questions, so she'd elected not to come again after that first time, though she'd still enjoyed it.

It was a Friday in mid-October, well technically Saturday now that it was midnight, and the moon was full and bright, but also limned in fog as Firenze had just said, giving it a yellow cast. I grinned at the centaur and plucked out some tied-together strands of hair out of the mokeskin pouch that Daphne had bought for me over the summer.

They were graying brown, though they gleamed oddly in the moonlight. Then I murmured a spell, and they gleamed brilliant silver.

Firenze recoiled and frowned deeply. "That is an abomination."

"Yes, it is," I agreed, "and I'm working to cure it."

"Ah," he said reflectively. "The moon is limned in fog, after all."

Those were Remus Lupin's hairs. The spell I used made them recall their connection to him, and thus they turned into werewolf hairs under the full moon. I'd been fascinated to study it during September's full moon, but since October's fell on a Friday during my session with Firenze, I'd decided to take advantage of that.

The hairs weren't magical or anything. Wizards didn't contain magic in their body parts, unlike magical creatures. But the spell I used to make them remember where they came from allowed me some insight into the curse. It wasn't about transforming people into wolves: it was about denying them their humanity, and worse than that, turning them into predators of men. Sure, that seemed obvious when you thought about it, but studying this made that a certainty, and one that was important to understanding and (hopefully) curing it.

And there was no surer way to mess with someone's humanity than getting your hooks in their soul. My magical sense had confirmed the connection with a few tests, doing my best to account for confirmation bias.

So, I had confirmation that the lycanthropy curse was hooked into someone's soul, but now I had to undertake the tremendous challenge of actually undoing it. Not to mention it undoing it safely, without mutilating the cursed soul in the process.

I'd been sensing the approach of several magical creatures, just as I'd hoped, and now I felt them strongly, as multiple pairs of glowing yellow eyes surrounded us, peering out of the gloom-shrouded underbrush.

Petty yelped in surprise, and drew her wand. "This is what you expected, right, Troy?" she murmured to me. I nodded, and she relaxed. Mafalda had tensed, but not pulled her wand, and I was touched at this display of her trust in me. Petty trusted me too, but she had developed a habit of never underestimating a possible threat; given her mediocre skills, she knew she couldn't let go of any potential advantage in a fight. Hence her instinctive wand draw.

The eyes stepped out into the moonlight, and I saw wolves surrounding us. But the instant the moonbeams hit them, they transformed, growing in height until they become anthropomorphic wolf-people, not dissimilar in appearance to werewolves.

The infamous werewolves of the Forbidden Forest.

They weren't werewolves though. My research had turned up the term wolfwyr, which seemed to work well enough. Wolfwyrs were extraordinarily uncommon, being the product of werewolves mating together during the full moon. They were intelligent and peaceful, and had wolf forms by default, taking a more anthropomorphic werewolf-like form during full moons, during which they retained their non-aggression.

"You touch the Man That Is Beast," said one wolfwyr, a woman. She was...reasonably attractive, if a bit furry for my tastes. "Why do you call us?"

"Man should not be Beast," I replied. "You are peaceful and whole, but your forebears are not." I could sense relatively little magic in them - other than being anthropomorphic and intelligent, they didn't possess any magic. It was also frankly astonishing how...peaceful that small innate magic felt. Lycanthropy was about the divide between Man and Beast, but wolfwyrs were in harmony with their natures. "I ask for your time tonight, so that I can study your nature, to gain insight into your forebears, and perhaps some of your hairs for future study."

"Oh hell no," Mafalda muttered, though I didn't know what she was talking about.

"A noble quest," said the wolfwyr. "An exchange then. Our bodies for yours. My sisters and I are in heat tonight."

"Fucking called it," Mafalda muttered again, as my eyes widened.

"Bright Venus ascends past the Wolf Star tonight," Firenze said, and I froze. I'd noticed that earlier, but hadn't paid it any mind due to my excitement about meeting the wolfwyrs. But if I'd paid it any attention, I probably could've seen this coming.

Though, if I'd kept in mind Not!Emma's tendency to add porn logic here and there, I would've seen it coming regardless.

"Very well," I nodded. I wasn't super keen on fucking furries, but they were reasonably attractive, so-

All the wolfwyrs howled, ululating to the moon, and the fur almost seemed to melt away, revealing tanned skin as they became kemonomimi wolf girls. Quivering ears and tails of gray fur, extra-long tongues dangling from their mouths as they drooled and panted in heat, long lithe legs, breeding hips, a varying range of bust sizes, and all with some bush (because naturally) around their dripping cunts.

This just became a lot more palatable to me, and I grinned as I wandlessly and nonverbally undressed myself.

A glance at Petty and Mafalda showed the former watching with lust and the latter watching with...also lust, but also some academic interest. Then I had no more thought to spare for them as the first wolfwyr darted up to me and licked my face, rubbing her boobs into my chest before flipping around and dropping to her hands and knees. The invitation was obvious, and I knelt, gripping her firm ass before driving my monster cock deep inside her lush quim.

She howled with delight as I impaled her with my immense slab of cockmeat, and didn't stop as I pounded her with rapid strokes of flesh on flesh. She bucked her ass back against my hips with every thrust. I released one of her hips to grab her tail, and pulled on it every time I thrust into her. She loved it, yelling even louder as I had my way with her.

I still had to do my divination lessons with Firenze (who was still watching the stars rather than us), and then attend to my girlfriends afterwards back in the castle, so I didn't want to take too long with the wolfwyrs, but I also didn't want to just rush through them, instead desiring to deflower and breed them properly.

I leaned over and grabbed her boobs, turning her latest yell of delight into a whine of ecstasy. I tweaked her stiff nipples in time with every hilt of my dick inside her soaked snatch, and she shook almost violently, juicing with her rapture and spraying fuckhoney all over my crotch as I kept hammering away.

Her tight cunt squeezed and rippled around me, so I picked up my pace, nearing my crescendo as I prepared to give her what her body demanded of me. With a final harsh grunt, I slammed inside her again and began spewing my thick ropes of nut butter inside her fertile core. Her belly distended, swelling with the sheer volume of virile spunk I seeded her with, as she lost strength in her arms and legs and collapsed to the ground, twitching around my cock and drooling happily.

I pulled out of her and stood up, and the eyes of my girlfriends and the wolfwyrs were all drawn to my dick. Throbbing and twitching, it gleamed in the moonlight from the femslime coating it, and I smirked at the wolfwyrs.

"Why are you such a horn dog, Pretty Boy?" Mafalda huffed, and Petty elbowed her with a knowing grin.

The wolfwyrs appeared to have an established pecking order, because there was no conflict about the order they took. The next one leapt into my arms; I caught her and lowered her onto my pole as she licked my face delightedly. I groaned in pleasure as her tight sleeve milked me.

"You don't have to just stand around waiting," Petty teased the other wolfwyrs, who perked up and surrounded me, slinking against my tall muscular body with their hands and tits as I fucked this second one.

It was going to be a long night...

I woke up shortly before lunch the next morning, having fucked all the wolfwyrs (and gotten some hairs for study), then concluded the evening's lessons with Firenze (though for a shorter duration than normal, given how late it was), then returned to the castle to fuck my girlfriends until dawn. Since sex didn't tire me, I felt refreshed now despite having ostensibly not gotten enough sleep.

Luna, Ginny, and Lavender (it'd been her turn to rotate into our dorm room to sleep with me) stirred soon after I did, and after giving each other good morning kisses I took the wolfwyr hairs out of my mokeskin pouch. I hadn't had much opportunity to examine them last night, but now I could easily tell the differences between them and Lupin's. Well, the differences of the beings they were connected to. As I'd hoped, the distinctions of how the beasts were tied into their souls highlighted where those hooks were. It would take significantly more study still, but I felt like now I had a path to follow. If I could just figure out how to safely remove all those hooks from Lupin's soul...

Ginny nudged me. "Food first, Troy. Then you can research."

I chuckled. "Actually, I have prefect duties after lunch too, come to think of it. Thanks for keeping me on task."

"That's what we're for," Lavender grinned at me. "If we don't keep you in line, who will?"

"Dobby," Luna answered her, quite seriously, and we cracked up.

At lunch, Ron was matching Petty bite for bite in how ravenous they were. Both of them had enormous appetites due to all the sex they were having. Petty because her slim frame needed the replenishment more than my other girlfriends (especially considering her enthusiasm and take-charge attitude among the harem), and Ron because the increased blood circulation from his transfiguration was tiring, most especially during sex when it also had to keep his horse dick erect.

"Hey Troy," he said to me, his mouth full. "What do you get the man who has everything?"

"I don't know, what?"
