Been wanting to do this idea for quite some time! Very happy to finally get this done and have some fun, super smutty writing to put out there again!

Thank you so much as always to Robert Baird for being the best dog and helping me improve this and make things more clear and telling me the merits of knotting good bitches.


Cassie shivered, pressing her hips back to the bucking hips of her boyfriend. She whimpered, her whole body shaking and glowing the pleasure. He held her face down, letting his hips crash against her in a steady staccato of motion. The thrusts from the wolf. The dingo's claws flared, digging into the sheets and clutching for purpose. She felt Leo's knot press against her lips, the tapered tip breaking down her cervix, a threat of force and pain that would only make her abused pussy grasp for his shaft.

She was seeing stars, panting hard and letting the moment take over.

"R-ready for it?" he snarled. His breath was hot on her ear. It was so deeply primal and made her whole body flush with lust. She nodded her head fiercely, barely able to accomplish even that basic motion.

"G-good bitch," he growled, tugging her hips back to his and slamming the knot in.

The sudden intrusion of his swollen knot into her sodden cunt was a welcome release. She clutched at his cock, squeezing and letting her walls spasm and quake with release. She came around her boyfriend's knot, feeling his cum fill her up. She whined and rocked her hips back.

Every time her boyfriend came in her, she was a happy dingo. The feeling of his cum warming her from within was such a welcome sensation. Getting it always felt like a reward, even if it meant the pleasurable discomfort that accompanied taking his large knot.

His strong arms pulled her body against his. He half-fell onto her and half pulled her close.

"Babe!" she laughed. "You're crushing me!"

"Well," he laughed, flexing his cock in her, making her vision go with it. "Yeah, that's the point, isn't it?"

"Ass!" she laughed. She laced her fingers with his, feeling him wrap his arms around her stomach. Soft kisses danced over her neck, tender and caring. She pressed her body back against his, her tail wagging nice and slow.

"Mmm. I love you too, Cass."

"Nnng, damn, babe. You really filled me up. Did you remember the towel for when you pull out?"

"You know I did," he growled with a nip. "You're avoiding saying it, you know."

"Saying what?" she smirked with a look over her shoulder.

He gave her butt a light pinch.

"Say it, bitch," he growled.

"Nnn, say what?" Cassie said, squeezing her walls around his invasive cock.

The wolf bit her neck and tugged on the scruff until his girlfriend yelped. She pressed back into his chest and kissed his hand gently.

"I love you, Leo. You know that, silly."

"I just like hearing you say that, can you blame me?"

"I can blame you for how sore I am right now, ass."

"But not complain, right?" His face was against hers. The soft sound of his voice in her ear was so intimate and full of the love from their time together.

The dingo grabbed her boyfriend's hand and laced their fingers together. She placed it on her belly and sighed into his chest.

"Never."

Allie's claws raked their way down the cat's chest. She rolled her hips, feeling the barbed cock press into her walls and tease her walls. She felt it rub against her g-spot with each full rotation of her hips. It filled her up so perfectly. The cat's cock seemed like it was meant for just her. Each time she brought her hips down, she seemed to whimper a little louder. She rode the leopard, rocking her hips on his cock and bouncing her body down onto his.

She was gasping at the feeling of his cock's hard pulses, each one a reminder of just how big he was.

He growled, hands going up to pull at each nipple in turn. "You want to get your cat off; don't you pup?"

She nodded her head, color burning into her cheeks.

"Then I want you to bounce for me!" He growled.

That statement was all that Allie needed. She leaned over his chest and started to bounce on him. She rode his cock hard, letting its length and size fill her up. It was so much, almost too much for her to take in. But she need it. She needed to get her handsome leopard off. She needed that feeling of his release. She _needed_to hear the two words that had such a magical effect on her when he said it.

So she did as instructed, riding her boyfriend, feeling his cock inside of her as she slammed her hips down onto his. It only got faster and more intense the longer it went on. It was just what she needed, what she craved. It was her rightful place, to be filled, fucked, and please her wonderful Master.

"F-faster, pup," he growled.

She nodded her head, letting her hips crash down, bucking hard and letting his length slam into her cervix. She was whimpering. It hurt, but it felt so magical and perfect. Allie had no idea how she ever managed to nab her wonderful leopard, but he was the only man for her. She was certain of that!

"S-sir, I'm close, sir!" she licked her lips, looking into his sparkling eyes.

"Well then," he flipped them over, pinning her onto her back and slamming his cock deep into hers.

She saw stars in the space between them. It filled up her vision and she panted, whining loud. The dingo's whole body was singing. He held her down, growling in a way that was so primal, so powerful. Her back arched, chest pressing into his to make sure he hit the right angle.

The leopard's claws dug into her hips, leaving indents on her ruddy fur. She whined and looked up at her, nodding her head to him. She didn't need to give him permission. Their relationship was predicated on that agreement that she was his fully. But she knew he still liked to see that permission and need from her.

She felt him release, his whole body tensed up and she could feel the warmth filling her up. She panted, eyes closing tight and focusing on that feeling of claiming, the primal way he bit down onto her neck that made her whimper. He was a true predator, and he showed it when he filled her up, trying to breed her even through her IUD.

The dingo's phone went off, buzzing loudly on her nightstand. The leopard reached over and grabbed it. He saw who it was on the other end and swiped up to answer that call. Allie's eyes narrowed, glaring her boyfriend down for stopping before getting her off to answer her phone.

"Hey Cassie, it's Tyson."

In their proximity, Allie could hear her twin's voice over the speaker.

"Oh hey Tyson! Allie around?"

Allie glared at him and shook her head. Tyson smirked at her, rolling two fingers over her clit nice and slow. She bit down a groan of pleasure as her boyfriend started to tease over her sensitive nub.

"She's around somewhere. I can go find her if I need to."

"Oh, it's not that important," Cassie said. "I just wanted to make sure you guys were ready for the trip this weekend. I'm excited to go to the beach house with you guys!"

"Oh, don't worry! I've been looking forward to that all month!" The leopard said.

His digits kept teasing her clit. But Allie's hands were clamped over her mouth, trying not to moan so her sister didn't hear. But that seemed to be exactly what Tyson had in mind. He only got more intense with his circular motions. She bucked her hips, moving around on his cock which only made it worse when she finally hasped in pleasure.

"Great! I know Leo's been excited for it. You guys are still bringing the booze, right?"

"Don't worry," Tyson smiled, looking down at Allie. "We're not getting off the hook that easily. Besides, I need to make sure we actually get good booze this time!"

Cassie groaned. "That bottle of Cupcake was one time!"

"And I'll never let you forget it, either." Tyson smiled. He rocked his hips back and forth, carefully fucking Allie while talking and joking with her sister!

Allie was going to kill him when he was off the phone with her. But she was going to kill him if he didn't get her off. She was whimpering, the feeling of his hips crashing to hers was magical and she managed to gasp out a quiet moan.

"What was that?" Cassie said.

"Oh, nothing! I think Allie just couldn't keep her mouth closed anymore."

"Are you--You're fucking her right now, aren't you?"

"Well... I'm making sure your sister is well and truly satisfied after she decided to wake me up with a blowjob." Tyson said it so matter of factly for something so deeply private and intimate!

"I can't believe you!" Both sister cried in unison.

Tyson dropped the phone into Allie's hands and worked double time on getting the moaning dingo off. The dingo tried to finish the conversation with her sister but it was quickly shortened when Allie hit the end button and grabbed the leopard by the face and growled.

"G-get me off already!"

***

Cassie danced in her seat to the music, her tail wagging behind her. She sang along to each word, feeling the warm summer sun through the window eating away at the cloud that a dreary winter and spring had left on her. She was in such a good mood and was so excited to see her sister and her boyfriend.

It'd been a few weeks since Cassie and Allie had seen each other, and the twins seemed to ache for each other. It was like part of them was missing, making it hard to enjoy things completely. Though they lived in different cities, each dingo felt the need to visit and catch up at least once a month. It was something that both of them had to explain to their partners each time a new one entered the picture. Some were more understanding; others were irate that they needed to share their girlfriend with anyone else.

Thankfully, Leo was more than happy to get together at the cabin. It was a gift from his uncle when he passed, and it was more than worth the taxes he paid to keep it. The lakeside cabin was cozy but it gave him a chance to get away and enjoy the chill of the cabin on a snowy day in winter, or the cool water on a sweltering summer day. The wolf was at home there, and chances were, he'd propose to Cassie there when the time was right. But for now, he was content to sing along with her, letting her good spirits infect him.

The car pulled up to a start and Leo put it in park. Cassie jumped out and spun around. She smiled at the sun and jumped a bit, her tail wagging behind her, legs shown off so perfectly in her shorts.

"I'm so glad we're here again! I've been telling Allie about this place since you first brought me and I know she needs the break too." She moved to the trunk of the sedan, opening it up and grabbing the cooler. She hefted it out, carrying it towards the porch before coming back for the suitcases.

"I know," Leo smiled. "It's gonna be perfect to see them again. I know that Tyson has been excited to go swimming in that lake. He used to come here as a kid apparently."

"Yeah, Allie's been telling me he's been making sure he's working out more the past few so you don't show him up in your swimsuit!"

Leo laughed, unlocking the door and opening it for the dingo who strained with the weight of the cooler. She set it down and turned back to see Leo's eyes on her ass in her shorts. She gave him a sly grin and wrapped her arms around her.

"Don't worry, Leo. I only have eyes for you and you know it!"

"I know," he said. "But still, your ass is hard for me not to stare at."

"Hush!" she laughed, kissing him and holding his hair with her fingers.

"Get a room!" Allie called. Her head was sticking out the window as Tyson pulled the SUV up the gravel path and parked it next to Leo's car.

Cassie unfurled herself from Leo and ran up to her sister. The twins crashed into each other, hugging and giggled. They spun around a few times. If not for the different shirts on, Leo could barely tell the difference between them. Their giggle and voices were so close that, on more than one occasion, he'd taken Allie's hand instead of Cassie's at family gatherings.

The sisters weren't the jealous types, which helped keep his hide on his back, he was sure!

Tyson grabbed a couple bags from the trunk, setting it down on the porch next to Leo before grabbing him in a tight hug. The leopard had definitely been working out. He wasn't in bad shape before, but his arms were larger now, and Leo could tell that the leopard had lost some weight around his gut from his hard work.

"Looking good!" he smiled, hugging the cat back.

"Thanks! After I saw how good you looked without a shirt on at Christmas, I had to get my ass in gear. Can't let some dog show me up!"

Leo was about to say something when Cassie came up to the leopard and smacked his chest.

"Tyson! Are you hitting on my boyfriend?"

"No, Cass, just stating the fact that your boyfriend's in good shape." He hugged the dingo and she kissed him on the cheek.

"Well, I can't exactly complain that you got him motivated to get into better shape. He's literally been sweeping me off my feet lately," Allie hugged Leo, her tail wagging at the reunion. She pulled back and leaned into her sister. The dingos gravitated towards one another naturally, the orbit of their sibling pulling ever stronger with them together.

Tyson gave Leo a sly grin and shrugged, as if it wasn't obvious that he'd used his newfound strength to pin her to a wall.

"Alright boys," Cassie smiled. "Let's get unpacked and go down to the water already! I'm so excited."

Cassie and Allie led the way into the house, letting both Leo and Tyson get a look at the dingos' butts, both hugged perfectly by their shorts.

***

Cassie and Allie sat next to each other in the waning sun while the boys were working on dinner. The dingo's tails both wagged in time with the other, swaying and dancing slowly as the smell of dinner made the twins' stomachs growl.

"I'm so hungry right now," Cassie said.

"Me too," Allie whined. "Honestly, I didn't even get the chance to eat much breakfast before we left. Tyson woke me up this morning with his morning wood and we lost track of time."

Cassie snickered, looking over at her sister. They were leaning against the railing while the boys were talking at the grill. On occasion they'd look back at their girlfriends and give an update on food, but mostly it gave the twins a chance to enjoy the eye candy.

"I can believe that. I know that Tyson's basically insatiable. The cat definitely seems like he can make you shiver."

"Mmm. I'll say," Allie sighed, looking up his back. She was clearly so smitten with her boyfriend that it was almost a shame to ask her:

"But have you ever been knotted?"

Allie's ears shot up. A grin started to form on her lips but was drowned out. She cleared her throat, brushing her hair behind her ear.

"N-no," she admitted. "I haven't."

The twin grinned, leaning in close. She wrapped an arm around her sister's waist nice and slow. "I can change that," Cassie whispered.

Allie tried not to react. She didn't want to make a scene but her sister's words were almost too much. She dropped her jaw and looked over at her sister.

"W-what do you think you're doing?"

Cassie shrugged. "I'm saying, that you and I have never done a swap before. And I have to admit, your leopard boy is a fucking stud. I'd let him destroy me."

Allie blinked and shook her head. She had to be misunderstanding her twin. She just had to. But the more she talked, the more that Allie knew there was no misunderstanding. Her sister was really talking about--

"I mean... Are you sure they won't notice? We've both been with them for a long time. I know that Tyson knows what I smell like."

"Well, we'd have to switch clothes first. We could get each other's scents on each other. Besides, just imagine Leo's fat knot in you. It's... Oooh it's heavenly, Allie!" Cassie leaned her head on her sister's shoulder.

"I... I mean, he's really hot, Cass. I've wondered about it before, not just Leo but, knots... No one in college was ever willing to knot me."

"Their loss, I'm sure," Cassie grinned at her sister.

"Alright," Allie said. "I'm game. Let's see how it goes!"

"Perfect!" Taking her sister by the hand, Cassie stood up and took a step forward. "Gotta use the ladies room, boys! Be back in a bit."

"Don't fall in!" Leo called, still working on the burgers on the grill.

Once in the bathroom, Cassie was quick to discard her top. She pulled it off and let it drop to the floor. Her lacy bra was red, hugging the dingo's perky C cups. She reached back and undid the clasp. She pulled her shorts down, shimmying slowly. Her tawny fur was full and luxurious. It caught the light, glowing a golden line around her shapely body.

Allie couldn't help but look at her sister. They'd done this before, but realizing that her boyfriend would be seeing her like that was surprising. It took some mental preparations to get ready for that. But she undressed too, grabbing her sister's bra and putting it on, handing the black pair to her sister. They traded clothes slowly, working out of one item, just to replace it with its twin.

When the sisters pulled the others' panties up, both of them looked at the other with a sly grin.

"Already wet?" Allie grinned. "That excited to see that cats are better than dogs?"

Cassie smirked. "You'll be a knot slut at the end of the night, I'm telling you!"

The transformation took maybe five minutes before they were dressed again. Cassie turned Allie around, looking at every inch of her. Allie looked her sister over and nodded. Her stomach was turning and she felt nervous but excited too. It was so hot to think about and Allie had to admit she was excited to try this. They talked about it ages ago but to actually do it...

Allie opened the door, going out of the house again. She opened the door, wearing her sister's clothes.

"Hey babe," Leo smiled at her. "Got something on your face there."

"Huh?" Allie started before her sister's boyfriend kissed her! He shut her down and the kiss forced any doubts in her mind away. She was going to fuck this wolf and kiss him all night long, and that made her wild with desire.

When the kiss finally broke, Allie took a step back, grinning at the taller wolf, his arm around her waist. She didn't even mind the sight of Tyson kissing Cassie, his strong body running hands over her sister's with rather possessive claws. His nose twitched, breathing in deeply with a contented chuff.

When the kiss stopped, Cassie flashed a grin at her sister.

They might just get away with it after all.

***

Cassie's arms wrapped around the leopard's shoulders. She felt his arm around her waist, pulling her towards him and she nuzzled into his chest. The smell of him was so different than Leo's. It was similar, with them both being predators, but there was something markedly different about it. It may have been something to do with the difference between species. It may have been the difference in the type of predators. Whatever it was, the dingo kept finding herself smelling the handsome leopard's chest, her tail thumping on the bed.

"You're happy," Tyson purred, rubbing his hand over her bare side. He laid down on the bed, down to his boxers in the hot summer night.

"It was a good day," Cassie said.

"Are you sure? Maybe you're just wagging that tail hoping I'll fuck you silly again."

Cassie leaned forward into her sister's boyfriend and kissed him. She felt her tail wagging, starting to sit up and move on top of him. Her curled tail wagging behind her and she looked down at him, the black bra and panties hugged her so close, her bust nearly breaking out of it while she rolled her hips down into his lap.

"You know that I'd like that, babe. So why are you holding back?"

Tyson's hands found purchase in her hips. Cassie was about to say something, opening her mouth to speak when she was suddenly turned onto her back. She gasped, her legs in the air and soon finding herself underneath the leopard's body. He tugged on her panties, pulling them down her legs, and off her feet. Her wet slit was pressed together, but the scent of it was apparent to her nose, so it had to be just as strong for Tyson! His growl was low and Cassie couldn't help but blush! He was so much hotter than she had imagined like this.

"You know what happens when you tease me, pup. Now, are you going to be a good girl for me, or do I need to teach you a lesson?" His face was down near hers and his breath was hot on her neck. She forced down a shiver, not wanting to show him just how much his words were affecting her.

"Teach me a lesson, kitty," she grinned.

The shadow that washed over the leopard's face was proof enough that Cassie had said something wrong.

***

Leo's hands went through Allie's fur. The dingo shivered, pressing her back to the wolf's chest. She sighed and found her tail wagging against her sister's boyfriend. She gasped when his hand went into her panties. They'd barely got into bed and she was already being felt up by the wolf she'd heard her sister tell her about for years now. She knew that she was going to get--

"You're soaked," Leo's voice growled in her ear.

She shivered, blushing hard at the growling words. She couldn't help but raise her tail, almost involuntarily. She reached back and her fingers wrapped around the wolf's sheath. He growled in her neck and Allie shivered. Her hips rolled hack, going from his bulge to the roaming hand. The wolf's fingers brushed through the dingo's lips.

"L-Leooooo" she whined, grabbing his wrist. It was so good to be teased by him, but it also felt so wrong! This wasn't her boyfriend, this wasn't Tyson's arms around her, his fingers teasing her mound. But she was so eager for it. The dingo's fingers tugged at his boxers, working them down so she could feel the wolf's thick red cock fill her hand.

"What's that, bitch? Did you need something?" he growled, nipping at her neck and making the dingo shiver.

"D-don't tease me!" Allie whined. She pulled back from him, squirming from his grasp.

"I don't know," he smiled. "Maybe I'm too tired to really give you what you want right now."

Allie narrowed her eyes. She pushed Leo's back to the bed and looked down to his cock. She wavered when she could finally see it. The size of it was something else, but his knot was at the forming stage. She shivered, looking at it, then back up to him. The dingo leaned down, taking his cock into her mouth.

The taste was... different than she was used to. It didn't have the same taste or texture as her boyfriend's feline cock. Instead it was smooth, and tapered at the tip but the farther she went down, the more it spread out. She pulled back only to slide down again. Her mouth wrapped tightly around the canine cock and bobbing nice and slow around him.

"Mmm!" she moaned, eyes looking up at Leo.

"F-fuck! Cass..." Leo managed. "You never go this fast! What's gotten into you?"

Allie grinned, hearing him say her sister's name and she moved all the way down. The sound of his gasps giving her all the indication she needed that he was pleased with her performance! Her head bobbed, taking it in, pulling back and diving back down. She needed him in a way that was hard to describe. She had to assume it was because of the species thing! It must be because she was the same species as him, it couldn't be anything else. It wasn't as if...

Leo's hands grabbed her head and pushed her down. She moaned and sputtered, gagging around the cock. Her throat swallowed, sucking on the cock that oozed pre into her mouth.

"Mmm!" she managed.

His hips pressed up, forcing more of that wonderful length into her maw. She whined a little, looking at him and rubbing her thighs together. She hadn't expected to be this turned on, but here she was!

"You want my cock so badly? Then you'll need to prove yourself," Leo grunted, starting to fuck her face with even thrusts. Her eyes closed and Allie focused as best she could on the cock that so perfectly invaded her mouth.

***

Cass found herself collared with her wrists in cuffs behind her back. She was face down in the bed and she could feel the rough, almost painful tongue pushing through her folds. She was writhing, caught between the pain and pleasure of the cat's tongue. It wasn't something she'd expected. Sure, she'd made out with a few cats before, but nothing could prepare her for the intensity of the situation of a tongue so sharp and soft at the same time gliding over her folds and making the dingo's legs shake.

Tyson's sharp claws poked her ass, tugging cheeks apart and keeping her nice and exposed for him. She was at his mercy, completely and utterly exposed for his probing, invasive, and immaculate tongue. Her breaths were coming in short, sharp bursts and the dingo's eyes closed in the perfect lust of the moment.

"So needy," the leopard chuffed, his voice smooth and deep and made the dingo's sex all the wetter with anticipation.

"I just want you, Tyson!" Cassie panted, her face flushed, her body exposed and arms behind her. She was at his mercy and the dingo kept pushing her hips back to his, wanting more from his tongue and his cock.

"I know you do," he grins. His claws ran down her thighs, bringing forth shivering moans from her. Every inch of her body sung with pleasure and Cassie struggled at her bonds.

She hated him right then. But she loved what he was doing to her! She fought the urge to yell at him, her naked form exposed and unable to do anything but accept what he did. Tyson's tongue dragged over her clit and her vision went hazy. She stifled a gasp as the tongue went up her silky folds, going up more and more until it glided past her tight pucker. She rocked her body back to him, a shuddering moan leaving her throat.

"Mm, I think you're needy enough," the leopard cooed. It was almost a purr but the sound of it hit something in Cassie she wasn't aware of. Canines were predators, sure, but they worked best as a group. A feline predator like the leopard behind her? He was predator that could take what he wanted on his own.

Cassie felt so helpless right then and it had her aching with a new kind of desire she'd never really experienced before!

Another new feeling hit Cassie right then. A weight thumped against her butt and she knew right away that it was the cat's cock. She could feel the barbs rubbing against her fur. It wasn't sharp per se, but it was intense. The feeling of it had her tail wagging just a little. She'd wanted to know what this was like for a while now, and here she was, about to--

"Wagging your tail now? Oooh, I didn't say you could do that, did I?"

Cassie froze her tail and looked back at him. She didn't know what came over her when she turned her eyes to him and said,

"Sorry, sir."

A deep, resonating chuckle escaped Tyson's throat and it made the dingo's already damp fur seem to grow into a sodden mess.

"Sir, that's _very_good. I expected I'd have to teach you a lesson again. But since you remembered that lesson from last month," he trails off.

Cassie's not sure why he trails off at first but the slow push forward of cock into silky, velvety folds answered that. She whined, her body growing rigid at the feeling of it. The barbs rubbed her walls from the inside, teasing her all the way in. She thought he'd stop, let her adjust, anything! But no, Tyson kept pushing, going down farther and farther until the large cat was completely filling her! His tip teased her cervix and it was so intense, so filling that she was having a hard time seeing.

The dingo looked at him, nodding her head in thanks for the sensation but instead of speaking, Tyson drew his hips back, making her shudder at the intensity of the stimulation to her sex. And when he slammed all the way in, hips crashing to hers in a loud plat, the dingo let out a whining cry of joy!

"Hope you're ready," Tyson growled.

***

Allie shivered, her hips rocking back and forth. She was sunk all the way to the knot on Leo's cock. The size of him made her shiver. Her body sung with pleasure and she rocked back down. The dingo held the wolf's chest, feeling his strong hands on her hips. She rode his cock hard, bouncing on his length and feeling it go all the way to the tip only to sink back down. Her dull claws dragged down his chest.

"Cass," Leo grunted. "Y-you trying to milk me dry here?"

Allie gave the wolf a grin. She wasn't sure of what she was doing until he said that. Yes, that _did_sound rather wonderful, didn't it? It really would make sense for the dingo to do exactly that, use her sister's boyfriend like a toy until he knotted her.

"F-fuck, s-slow down!" he moaned. He ran his hands up her body and grabbed her head. She felt herself flush at the intense look he gave her.

Why couldn't he understand? This was what she needed! She didn't need that tenderness she needed.

"I need that knot, Leo," she whined. "I don't know what's gotten into me, but I need it, I need I-- "

The wolf flipped her over suddenly. She was on her back, the wolf on top of her now. He had her legs up on his shoulders. He looked at her and gave a wolfish smile.

"Alright, bitch. You want a knotting so much?" He slid back into her, pushing his length deep into her body. She gasped at the intrusion. With her legs together in that position, she was so much tighter and the feeling of his knot pressing to her lips.

He started to fuck her slowly. Each thrust was followed by a moment to recover before he slammed in again. She groaned, her body writhing in pleasure. She was fully his bitch in that moment and every hard, crashing thrust forward pushed a knot into her lips, almost tying her at every thrust!

"Yes!" Allie cried. Her voice was matching her sister's next door. They were being fucked by each other's boyfriends one wall apart. It wasn't part of the plan, it wasn't anything she wanted, but hearing her sister screaming like that for her big, handsome leopard made the fact that she was being fucked by her sister's boyfriend all the hotter. She grabbed his arms, moaning as he used her.

"You want the knot so much? Beg!"

***

Tyson had one hand on Cassie's tail, the other on her head. He held her down, pounding roughly at her sore cunt. They were shallow, hard thrusts, but each one had her breasts bounce towards her face, her eyes closed and moans escaping her lips.

"Allie, you naughty slut!" Tyson snarled. "Had to be so needy like always! Couldn't wait, huh?"

Cassie nodded her head in affirmation. She was his right then, not Leo's, but his. And somewhere in her, hearing her sister's name being growled by the male fucking her made her squirm with delight. She pressed back, clenching around the cock that battered at her and made her eyes go cross. She whimpered as the dingo came right around the invasive cock. She came hard, soaking the cock in her juices and her eyesight went hazy. But Tyson wasn't stopping!

***

Leo's thrusts were slower than ever, but each one pushed the knot further. Allie looked up at her sister's boyfriend, ready for it. She was ready for that sensation, ready for--

It slammed in all at once and she came. She came around the knot, feeling her body get filled and stretched so impossibly full that all air was out of her lungs. All thoughts were expunged. She was full of cock and knot and, judging by the warmth filling her deepest recesses, cum, but nothing else! She wasn't able to form a thought or do anything else but marvel at the totality of the knot that had her panting and whimpering up at the male that tied her.

She looked at him, holding his arms and feeling his cock throb deep inside of her. The bitch was his, and he was her stud. She was rubbing his arms, or maybe she was scratching them, she wasn't sure. But she moaned at each minute movement he made, the tie keeping them together so much more than Tyson's did after he finished.

And she still oved her boyfriend, nothing would stop that, but to be filled like this was so perfect and woke a feeling she wasn't prepared for!

***

Tyson kept his crashing hips going. His arms were now around her stomach and each thrust had her gasp and moan, her whole body being pulled and pushed, his cock guiding her wherever he wanted. She was used to a knot, but something about the barbs and the almost painful, but pleasurable feeling of the cock filling her up made her next peak come again. She was rocking from one orgasm to the next, each one making her eyes go cross, and her vision go hazy.

Cassie heard her sister moan, the cries of gasp that she was certain came from being tied. She glanced back at him, feeling his breath on her neck and the sharp teeth that bit into her scruff. She froze up, accepting her place beneath him as he started to cum. He filled her, ropes of cum flooding her, filling her up and getting his scent all over her! She loved how completely, and utterly claimed the predator made her feel. Cassie leaned back, trying to get more from him, needing it all. But he just pushed her down into the bed and turned off the light.

She could vaguely remember being unbound. She remembered him kissing her, holding her close to him, and the thumpthumpthump of her tail. But Cassie was pressing her nose into his chest by then. She couldn't focus, too hazy and fuckdrunk. She was tired and it wasn't long before she closed her eyes and drifted off to sleep.

Leo and Tyson worked together on breakfast the next morning. Each of them grinning and shooting each other looks when Allie and Cassie walked out of the bathroom. They'd changed clothes back, showered and talked. Neither could admit who was better. It was so hard to choose which was better when both of them felt so good from their night of trading boyfriends.

Cassie went over to her handsome wolf and kissed him. She loved him so much and put every bit of her love into kiss. Her tail wagged slowly and she sighed at the feeling of his arm around her.

"I love you," Leo said to her. He placed a soft kiss to her nose.

"I love you so much," Cassie smiled, holding her boyfriend close.

Allie was pulled into a hug by Tyson. She didn't even fight it. She held him close, nuzzling in and feeling the strong arms of the cat she loved so very much. She sighed and looked up at him, melting a little at the grin that filled his face and into his eyes.

"I love you," Allie smiled, rubbing his hips nice and slow.

"I love you too, pup," he grinned.

The girls grabbed the plates of food, taking it out to the patio to enjoy the warm summer morning. It left the wolf and the leopard alone together.

Tyson grinned at Leo and gave his shoulder a light punch.

"I can't decide if I liked Cassie more than Allie after one night. Maybe we try that again."

Leo nodded his head slowly. "Just don't be upset if your girl gets a toy with a knot. She seemed to love that last night."
