Gwyn loved the wilderness. Perhaps more than anywhere else, it was here that she felt truly home. Among the thick canopy of emerald trees, the woods came alive with a symphony of chirping birds, rustling leaves, and the occasional distant howl of other creatures fighting for survival. Streams of sunlight filtered through the foliage, creating dappled patterns on the forest floor. The earthy scent of damp moss and fallen leaves enveloped her senses, grounding her in a comforting embrace. But she could admit that it could get lonely, even with Fenrir, her fierce and loyal companion, always at her side.

She glanced into the cave, where her giant white wolf companion was pacing in circles like a trapped predator. He hated these colder months probably more than even she did, when she was forced to seek refuge in caves or abandoned huts to shelter from the biting cold. Soon, the winter snows would drape the landscape in a shimmering white blanket, and she'd have to bid farewell to the wilderness she loved so much, including Fenrir, and take shelter in the nearby village until spring arrived.

The thought of leaving him behind tugged at her heart. But the villagers' fear was not entirely unfounded, for Fenrir was no ordinary wolf. He was at least twice the size of a normal wolf, with long and pristine fur that glistened fainlty under the silver embrace of the moonlight. His eyes were deep pools of amber that often seemed to hold an understanding beyond that of an animal. Sometimes, when he gazed at Gwyn, she felt as though he could peer into her soul. That's why she'd called him Fenrir, after the great wolf and son of the god Loki.

The villagers often whispered fearful tales of a werewolf roaming the woods, and some believed it to be Fenrir. But Gwyn had spent countless nights under the full moon with him, and she had never witnessed any transformation.

It seemed as though Fenrir sensed her inner turmoil, for he lifted his head and let out a sorrowful howl that resonated with her soul.

She had no idea how they had ended up so close. Their bond had only grown stronger ever since that fateful day when Fenrir had saved her from a bear attack. Perhaps it was the shared loneliness of wandering the woods alone that forged their connection.

As the day surrendered to the night, the forest transformed into a realm of deep shadows. Gwyn and Fenrir found themselves nestled in the large cave-like crack edged into the side of a mountain, surrounded by rock and ancient trees and a full moon glowing in the night sky.

Gwyn, feeling the chill in the air, knew that this night would be especially cold. She tended to the crackling fire and pulled her cloak tightly around her shoulders. Yet, as the night lingered, the cold seemed to gnaw at her bones, biting through layers of clothing.

Exhausted, she finally sat down beside the fire, hoping she'd be able to find some rest despite the cold. Her eyes grew heavy with weariness, but her body's shivers kept her from finding sleep.

Fenrir, returning from his nightly hunts, must have noticed her shivers, for he whined softly as he entered the cave. He approached her, his large white form shimmering in the darkness. He nudged her with his muzzle before he nestled beside her, his thick fur acting as a shield against the biting cold. He folded half of his massive body over hers, radiating a comforting warmth that made her expel a weak moan.

The gentle rumble of his growl made her feel as though he approved of the sound. As they lay together, Gwyn couldn't help but marvel at the magical aura that radiated from her wolf companion. She closed her eyes, lulled by the flickering flames of the fire, and began stroking along Fenrir's fur to let him know how much she appreciated his warmth.

"What only would I do without you?" she whispered against his fur, hoping that--just once--he could speak her language.

He growled and licked across her face. It tickled a little and Gwyn chuckled, but she never ceased caressing his back. Fenrir's eyes flared bright amber in the growing darkness, and Gwyn felt him shift closer, dragging more of his weight over her so that she was pinned beneath him--unable to move even if she wanted to.

"You do realize you're about three times my weight, right?" she said, smiling at him. "Don't crush me."

In response, he pushed his muzzle into the crook of her neck to lick her skin, and she involuntarily moaned as a shiver coursed through her body. Fenrir had licked her before, but never quite so... intimately. Usually, he was just playful. But this, this felt different. Purposeful.

His surprisingly smooth tongue swept up her neck and over the curve of her jaw, then over her mouth. As his massive head towered over her, a part of her wondered if she should feel afraid. But, looking up at his majestic shape, the glow of his fur, the intelligence in his beautiful eyes, she could only produce a feeling of longing.

"What are you doing, Fenrir?" she whispered. "What do you want?"

He licked over Gwyn's mouth again, as gently as one could expect from a creature of his size. She yielded, partly out of curiosity, and parted her lips. He let out a low growl, making it clear that he was not yet satisfied with that. Still, he licked over her lips again, seeking to connect with her mouth in a way that was simply not possible for two species so different.

So Gwyn opened her mouth further and let her tongue slip out. She had no idea what drove her to do such a thing. Shame filled her but it evaporated quickly as Fenrir's approving growl rolled through the cave.

He grazed her tongue with his own, slowly at first, then faster, until she began to move her own tongue against his. Something about it made him pull back, and he howled at the moon. His weight shifted off her, only for him to reposition himself between her legs. When he lowered himself again, she felt his erection press against her thigh. There was no longer any doubt as to what he craved.

Still, he did not push for anything, as he simply snuggled against her, continuing to lick her face. From time to time, he would nibble on her neck by pressing his sharp teeth against her skin, while his erection would push against the spot between her legs.

It drove her almost mad and Gwyn realized that she wanted him inside of her. The thought was wrong. She didn't even know if such a union was possible, but she wanted it nonetheless.

"I want you, Fenrir," she said, her voice low and full of desire. "I don't know if you can understand me, but I think you do, and I want you."

Fenrir looked at her, those amber eyes bright and knowing, and he gracefully lifted himself off her. Gwyn reached down to undo the buttons of her blouse, then those of her trousers, before laying back down with nothing on but her skin. Fenrir watched her patiently, his erection jerking in anticipation. Once she was done, he stalked over and let his tongue glide over the length of her body.

"Please," she begged, spreading her legs for him. "Fenrir."

He seemed to listen as he stepped between her thighs, lowering his hindlegs to let his cock align with the entrance of her pussy.

"Oh my god," she said. "This isn't happening, is it? This must be a dream."

Fenrir growled at that, before moving his hips forward, so that his cock would push against her pussy. His cock was huge. Easily double the size of a human's. But she swallowed her fear, letting him set the pace, trusting him completely.

"Don't hurt me," she whispered.

Fenrir leaned down, draping his soft body over her chest, his tongue licking her neck as if to reassure her. All the while, he guided his cock into her, filling her a little more with each shallow thrust.

"Oh my g--"

He cut her off with his tongue as it swept into her mouth. He thrusted once more, and then his cock was fully inside her. It did not fit all the way. Not that Gwyn cared much. She had never felt this full. This stretched. This wanted.

Fenrir's hind legs lifted as he started to push into her, using the full strength of his body. It was completely animalistic. Almost inhuman, if it weren't for the tender touches of his tongue that slid over her neck, her lips... everywhere he could reach.

Gwyn lifted her head to look between them, to the spot where they were connected. The sight shocked her, literally, as it sent sparks down her back. His cock was bulging, covered in small, glowing spots that matched the shimmer of his fur, and his knot was pulsating, begging for release. Even as he continued fucking her, and she watched his cock disappear between her legs, she couldn't fathom how it possibly fit.

"I'm sorry you won't find complete release with me," Gwyn mumbled in between thrusts, "it'll never all fit."

Fenrir paused, then withdrew from her, leaving her feeling utterly empty. He pushed his muzzle between her legs, letting his tongue glide over her pussy and then--very deliberately--over her asshole. He pushed the tip of his tongue into her ass, just a little bit, and the meaning of it became clear.

"What? No. We can't. It would hurt too much."

He howled again, then swung his head from side to side, as if to disagree. He climbed over her and bit her neck again, this time harder--just enough to break her skin. She recoiled, but his weight held her firmly in place. His bite was sharp, but the pain almost instantly faded, and instead a warmth spread from it, filling her with a sensation she couldn't place.

With her neck clenched between his teeth, he turned her around on her belly. He released her neck, and she landed on all fours. Before she could so much as object, he was already behind her, hugging his front legs around her shoulders and mounting her.

He pushed the tip of his cock against her ass. Gwyn was prepared to scream when she realized that she felt nothing. Just the dull weight of movement.

What the hell? Did his bite do that? Did it... numb her?

Fenrir's cock pushed against her asshole, and she felt it slip inside, yet there was no pain. No pleasure either. It was simply an awareness of pressure against skin. She wondered how long it would last.

He continued mounting her from behind, slowly pressing his glowing cock into her tight ass. Her body resisted, and it seemed to take an eternity until she finally felt his fur brush against her ass cheeks. She wondered if his knot was already inside of her, or if he'd save it for last.

His thrusts continued. This time, he was rougher with her, more animal-like, as his large, thick cock slipped inside of her ass over and over and over. Eventually, the numbness seemed to fade from her body, and she started to feel his cock more acutely. The hairs on her body raised as goosebumps covered her skin. Suddenly, she started to feel extremely full. Extremely stretched. Her asshole was burning, and when she glanced down her body, she could see his knot slap against her ass cheeks.

At last, Fenrir's thrusts became fast, uncontrolled. With a deep growl, he pushed her head down into the ground. He bent down to wolf-kiss her mouth again, and she let her tongue hang out for him to lick as he pleased.

The next time he thrust into her, he pushed all the way, and she felt her ass stretch impossibly wide as he forced his knot inside of her. She screamed in both pain and pleasure.

Fenrir collapsed on top of her, firmly locked inside of her ass, and continued to gently lick her face as they lay there like that under the full moon. His cock was throbbing inside of her, and she could feel his cum burn her insides.

Gwyn didn't know how much time had passed when the strong rhythm of Fenrir's heart eventually lulled her to sleep. With his fur keeping the cold away, and his knot still pulsating inside of her ass, she eventually fell asleep to the slow, soft kisses of his muzzle.
