The next morning Arya seeks out some fun... and finds it!

Arya frowned as she made her way through the Godswood, wondering just what was going on in her home.

She’d arrived at breakfast to find her mother in a fit but for once it hadn’t been her that had caused the Lady of Winterfell’s anger to rise. Her mother had refused to say what was wrong, merely snapping that Arya was to behave while she went to have words with Septa Mordane, and stormed out of the hall, leaving Arya seated all by herself at the great table, something that had never happened before. After a while, when no one else had come down, Arya had worked up the nerve to ask one of the servants what had happened and she’d learned that one of the serving women had gone to awaken Sansa only to find her room an utter mess and a letter from Sansa stating that she had important matters to attend to and her mother shouldn’t worry.

Arya could understand that upsetting her mother; she got mad if it came out that Arya had left dresses lying on the ground. So Sansa, perfect little Sansa, leaving her room looking like burglars had ransacked it and then being utterly dismissive about the entire thing? Yes, that would drive their mother up the wall.

Deciding that it might be best to stay out of her mother’s way Arya decided to head into the Godswood and spend her morning climbing trees, skipping stones along the dark pond that lay beneath the Heartstree, and pretending sticks she found were Valyrian Swords that she could claim as her own. It was far better than attending her lessons and-

Nymeria began to whine behind her, ducking her head while her tail went between her legs.

“What is it girl?” she asked, reaching down and petting the direwolf. She had never seen her dear pet act like that before. “Come on, it’s okay.” Arya began to walk again and after a moment Nymeria followed… but it wasn’t with her usual excite bounds. Now… it was careful. Slow. Cautious. “You are being rather odd today,” she said as she rounded one of the larger trees and came upon the heartstree pond…

…and stared in shock at the massive 9 foot dragon man lazily bathing in it.

Arya and Bran had once gone swimming in the pond during a very warm day and she knew that the first feet of the pond were shallow before it began to rapidly dive down. Her father had warned them all to be careful, for the pond was very deep at the center. That was how she could tell the massive creature before her was huge, for where he was standing would have seen the water above his head but she could see his firm ass, meaty tail, and muscular back with wings fluttering slightly as he cupped his hands to gather water and pour it over him. He raised one handful above his head, letting it wash down over his thick mane of black hair before letting out a rumble of pleasure, stretching his arms far above him. Arya could only stare in shock as he turned towards her, eyes closed, and she saw the front of him. Long snout with sharp teeth. Broad shoulders and chest with scales running down his body. Thick arms full of corded muscle. And a truly gigantic cock that seemed more like another beast entirely than a piece of him. And then there was the smell… an exotic stench that made her screw up her nose even as she sniffed again, trying to place it.

“Like what you see?” Sansa said behind her and Arya let out a yelp, whipping around and forgetting that there was a scaly red monster near her.

“Sansa! Don’t you… scare…”

Arya trailed off as she realized that instead of looking at her sister’s eyes she was instead gazing at a muscular furry red belly. Slowly Arya looked up only to realize she needed to back away a few feet due to the truly ginormous breasts that huge off the new arrival’s chest. Arya had never seen breasts so big, the nipples nearly as large as her fist and as dark as the night sky. Now back a few feet she was able to see more of the new monster that had come upon her, gazing with shock at the wolf-like head that topped the muscular torso, a long mane of red hair cascading down to her powerful shoulders and arms.

“Mmm… or maybe you like me instead,” the monster said… in Sansa’s voice.

“Now now,” the dragon behind her said and Arya spun around as he came out of the water, gallons of water falling from his massive form, “be nice Sansa. We are impressive.”

“J-Jon?” Arya stammered. She found herself backing away only to collide into her huge furry sister, which caused Sansa to laugh. “Stop it!” she snapped, pushing aside her worry and shock at how they looked and focused instead on her annoyance that once more Sansa was laughing at her. “How… what happened to you two?”

“Like it?” Jon asked with an arrogant smirk, flexing his arms so Arya could see just how strong he truly was. She turned to see Sansa doing the same, preening over her biceps. “An improvement, wouldn’t you say?”

Arya licked her lips, the strange musky smell becoming stronger and making her feel a bit dizzy. “Y-yeah,” she got out.

“And you tell me to be nice,” Sansa said as she walked around Arya, her huge furry feet slapping against the hard ground as she went over to Jon and began to cuddle up next to him. “Flirting with her when you know she could NEVER handle you.”

“I… I could handle him!” Arya said.

“You don’t even know what I’m talking about,” Sansa challenged.

“I do too!” Arya snapped, stomping her foot only to wince; her shoes suddenly felt rather tight.

“You’re just a tiny little girl,” Sansa taunted.

“I am not!”

“Arya Underfoot… quite literally.” Sansa lifted up her leg and wiggled her toes. “I could cover you with my entire foot now.”

“You could not!” Arya shouted, reaching out and smacking her hand against Sansa’s padded foot only to cause her sister to laugh. “Shut your stupid mouth!” Arya said, her voice cracking as she balled up her fist, shoulders hunched and body trembling. “Just because you’re older doesn’t make you better than me!”

“Is that so?” Sansa asked, raising an eyebrow.

“Yeah!” Arya declared only to wince again; why did her shoes feel so tight? And her dress was pinching into her skin. And every time she breathed in that hot wonderful musk got in her nose and she didn’t want to fight with Sansa she wanted to keep breathing it in! “If I were the older sister everyone would say I was better than you!”

“If you were older?” Jon asked, raising an… well, not an eyebrow as he didn’t have them anymore but a brow all the same.

“Yeah!” she declared, having gotten so worked up she’d completely forgotten that her brother and sister weren’t human anymore but muscular monster people. In fact it seemed… right… that they looked like that. Like she was the one that was the wrong shape and they were the ones that were natural and correct.

“Say it again,” Jon whispered.

“If I were older-“

“Not if,” he cut her off. “You want to be older?”

“Yeah!”

“You want to be an adult?”

“Yeah!”

“Again!”

“I want to be an adult!”

“Okay,” Jon said and with that he leaned down and blew a blast of hot air on her and Arya let out a guttural moan as the delicious spicy scent that had been driving her crazy flooded her brain. She swayed and wobbled and dimly felt her shoes burst open and the front of her dress tear. She took a step only to find the ground suddenly a lot further away than it had been a moment again and another step saw it retreating… no. No it wasn’t retreating. She grabbed onto her dress and tore at it to let her to breathe as she realized what was happening.

She was growing.

“I must admit,” Sansa finally said, “father was right… you did grow into your face.”

Arya, stumbling forward thanks to having half her shoes on and half torn away to leave her barefoot, moved towards the dark godswood pond, Jon and Sansa parting so she could get past them. She felt the two of them beside her as she dropped to her knees and looked at her reflection. Gone was the long face and skinny boy body and mousy hair. Now she sow long sharp features, dark waves of hair that came down to her shoulder blades, and a body that, while not as buxom as Sansa’s had been (when she was human) did have flared hips, small but firm breasts, and a lean frame. She wagered she was now a woman grown, just as she had demanded before Jon had blown that air on her.

And… it wasn’t enough!

She stood up and kicked off her ruined shoes, marching towards Jon and Sansa who still towered over her. Her sister was looking at her in amusement, clinging to Jon as her tail wagged, one arm wrapped around her shoulder while she ground her naked slit against his muscular thigh.

“I can handle him now,” she told her sister in challenge.

“You’re grown,” Sansa admitted before reaching down and stroking Jon’s length. Even though she had only been an adult for mere moments Arya found the fog that musky scent Jon was making parting enough to allow her brain to flood with all sorts of information on the ways of man and woman. It was a primal instinct… after all, a wolf wasn’t taught by their parents how to make pups. Nor was the cat or the bear. They just knew.

And now Arya did too.

“But you still can’t handle him,” Sansa taunted.

“Watch me,” Arya said confidently and with that she smacked at Sansa’s hand, her sister removing her claw tipped fingers before taking several steps back. Every movement she made was full of power and grace but Arya refused to focus on that. Instead she kept her gaze on Jon’s massive scaly cock and gigantic balls, his height making it that she was able to look the girthy monster head on.

“Are you sure, little sister?” Jon asked, his voice taking on the same teasing tone he’d used whenever she demanded he teach her something like shooting a bow and arrow or using a knife.

And just like those times rather than answer she went into the new task with utter determination.

Her hands, no longer stubby starfish but instead strong with long nimble fingers, reached out and wrapped around his cock though it was so big she had to use both hands and still didn’t reach all the way around. She began to stroke him, up and down, feeling the heat he was generating. The scales weren’t rough like she’d thought… instead it rather reminded her of leaves wrapped around a length of warm iron and velvet. He was so big and so hard and being that close to his cock made the musk she was breathing in all the more strong and potent. She felt utterly drunk but she wasn’t going to move away.

“So eager,” Jon groaned.

Arya, rather than answer, found herself compelled to lean forward and begin licking his dick like it was the best treat in the world. And… it truly was. Warm and salty Arya found the only disappointment was that she couldn’t get even the tip into her mouth, it was so big. Her tongue darted along the tip and the hole upon it and gathered up his wetness, swallowing it down.

She breathed in, nostrils flaring and eyes fluttering and when she was able to focus again she saw that her hands were larger… and that gray fur had began to creep along her wrists while her nails grew longer and darker.

“Such a savage girl… everyone always said that,” Sansa said, moving to stand behind Jon. But rather than interfere Sansa wrapped her arms around him, running her hands along his chest as Arya stroked his length. “Everyone said it, little sister… we just didn’t understand.”

Arya nodded, realizing what was happening and why Sansa was suddenly being so kind. Sansa had been challenging her before, seeing if she was strong enough, worthy enough, to join them. The insults, the mockery… it had been to encourage her to take the plunge. And now that she had proven she was ready, that she was worthy… her sister was welcoming her.

“Come on Arya…” Sansa whispered, reaching down with one hand and rubbing her head. “Join us.”

Her dress tore as she began to pump harder, her mouth slobbering along Jon’s length. She felt herself rising, her shoulders making the seams of her dress pop. Her feet dug into the ground and soon she had to squat in order to keep her face level with Jon’s erect penis. Every breath made her clothing buck in protest but they couldn’t stop what was happening. The hated dress, the symbol of her mother trying to **** her to be something she never wanted to be, was torn to shreds as her torso grew. The breasts she had just gained swelled like bread dough, the neck hole of the garment tearing so that when she looked down she could see her pale skin darkening, her nipples becoming black while gray fur covered her skin. She fell hard to her knees as she stretched out her tongue, it growing longer and flatter and rougher as she lapped at Jon’s erection, urging him on. Her bones popped as her hips widened and her ass exploded out, her tail bone shooting out and forming into a thick tail. Arya opened wide and finally was able to suck Jon’s cock into her mouth and the moment she did so her nose stretched out along with her jaw, forming a muzzle as her teeth become sharp fangs. Arya bobbed her head back and forth as her brother groaned.

“Yes Arya,” Sansa said, cheering her on. “Yes… do it… pleasure our mate… take him all… do it… do it…”

Arya felt Jon stiffen and knew at once in the deep recesses of her brain that if he came that would be it. His cum would complete her transformation. Her humanity would be gone forever with no hope of ever returning.

She slammed her head forward, feeling him slide down her throat as her wet nose rubbed against his belly.

Jon roared as he came, flooding her belly with his seed and Arya shook as the magic-laced cum caused her pussy to gush as her first orgasm ripped through her.

When Arya finally pulled away she licked her lips and fell down onto her huge ass, staring up at Jon. Sansa let him go and moved towards her, offering her a hand and Arya, after a moment, accepted it, allowing her sister to help her to her feet.

“I don’t think I can call you my ‘little’ sister anymore,” Sansa said, cocking her head as she looked her over. Arya looked down and found she agreed. She was the same height as Sansa, just a few inches smaller than Jon but that was right… she knew he should be bigger than them. While Sansa’s coloring was red Arya’s was dark gray with a deep brown mane that reached down midway to her back. Her breasts, if compared on their own, were huge; she had to shift in order to see her feet. But Sansa’s were still bigger than her’s. Not that Arya minded because her ass was larger and she gave it a wiggle, liking how it jiggled and shook along with her tail.

“More like twins,” Jon said, leaning against the Hearttree, his hand around his dick as he lazily pumped it; it was clear he was already full and ready once more.

“Mmmmm,” Sansa said, snuggling up to Arya, wrapping an arm around her and pressing her tits against her’s. “I like that… don’t you?”

“Very much,” Arya agreed, resting her head against Sansa’s shoulder as she felt the connection snap into place; they were no longer the big and little sister. They were truly twins now. She looked at Jon before back at Sansa. “Mother always did ask us to get along…” she began to walk forward, Sansa matching her step for step.

“To learn to share,” Sansa said as the two of them dropped to their knees.

“To work together,” Arya said and the two wolf women opened their mouths as their alpha gave his cock one more pump, spraying his cum all over the two. Thick streams rained down on them, far more than a male should have, not that the twins complained. They licked up what they could then focused on licking each other clean, Jon sitting down and opening his arms up so that Arya and Sansa could curl up on either side of him, the two unable to stop themselves from rubbing their hands along his chest. “What now, Jon?” Arya asked as she saw Nymeria, Ghost, and Lady all approach and bow their heads, submitting to three apex predators. “Other than more mind blowing sex?”

“Sansa and I have been discussing it… I am more than enough for each of you but I think my lust is too much for just you two.” He began to scratch the two behind their ears and Arya’s tail thumped while Sansa’s leg wiggled. “You two are my first and second but I think we need more… to explore just what we can do. Because I can feel it… this is only the beginning.”

“You always wanted to see Westeros,” Sansa told her.

“You are talking about FUCKING Westeros,” Arya informed her sister, nuzzling her face against Jon’s chest, longing for the contact her pack could give her.

“Yes,” Jon agreed. “Though… I think there is one more thing left in Winterfell before we head out…”
