"It's not fair, they always do this!" Mia Bishop whined to her older brother with tears in her eyes, a day before her eighteenth birthday and her parents had told her they wouldn't be home in time to make it.

"I'm sure they're doing everything they can to try be here..." Sam Bishop, always the level headed one of the pair tried to reason with her. He understood why his younger sister was upset, after all their parents had missed her sweet sixteenth as well due to work commitments. But living the lavish lifestyle both kids enjoyed, Sam understood why they worked so hard. He just wished that this birthday would be better than the last few for his sister. His heart ached seeing the pretty young white she wolf curled up on the couch, arms wrapped about her knees as she curled into a ball and hid her face now stained with tears.

She was a good kid, did well at school and never got into any trouble. Mia really did deserve a memorable birthday for a change, or at least not to spend it alone. Sam's lips curled into a sly smile as an idea began forming in his mind, slipping from the room to message his parents to request money for "party supplies" so he could enact his plan. Within a few minutes Sam's mobile dinged with the notification that the money had been transferred, giving a little fist pump into the air he headed back into the lounge to find Mia still curled up and sniffing quietly on the couch.

"Hey sis, Mom and Dad sent me some money through for your birthday. I was thinking that maybe you could invite a couple friends around for an old timey sleep over, order in pizza and rent some movies? Also, if you're keep it a secret between us...I'll even get you guys some booze..." Sam leaned in close to whisper the last part into his sister's ear as if there were others around listening.

"You're joking, right? Mom and dad would never allow it..." Mia sat up with a skeptical look as she scanned her brother's face, trying to determine if he was teasing her or not.

"They don't have to know, it'll be out little secret! I'll even get out the house for a bit so you and the girls can go wild!" The older white wolf felt happier seeing his sister actually beginning to smile as she leaned in to give her older brother a hug.

"Thanks Sam, you're the best" Mia sniffed one last time as she hugged her brother tight, resting her head on his toned chest.

Early on Friday afternoon at a little after 6am, Sam snuck into Mia's bedroom with a red velvet cupcake and a candle already lit. He grinned as he began humming "Happy birthday to you" softly at first, but eventually he would be humming decidedly hard right up against his sisters ear until she sat up bleary eyed and wild haired. It took a moment for her to register what was going on, but when she did, even in the dim light of her bedroom her smile was radiant. Leaning in to blow out the candle with one little puff before taking the small plate and setting it aside to give Sam another hug.

"So what did you wish for?" Same asked curiously, noticing the way Mia smiled at him as she blew out the candle.

"If I tell you, it won't come true" laughed the white wolfess before she ushered her brother out so she could shower and get changed.

With the lounge decorated and prepared for the days and evenings events, Sam headed off to go buy the remainder of the food and drinks while Mia waited for her guests to arrive. By the time he got home, Sam could already hear the loud chatter and laughter of his sister's friends, especially the rather lively snow white husky girl Paige Mitchell. She and Mia had been friends since kindergarten, she had spent so much time at their place that she was like another sister to Sam, which did kind of make it awkward now that she'd grown into a beautiful young woman too. If it weren't for their history together and Paige being his sisters best friend, Sam would definitely tap that ten ways from Sunday and then some.

As he walked through the front door carrying the heavy bags of food and drinks, muscles tensing under his already tight top, he would be met with a chorus of cat calls and whistles. Sam merely shook his head and laughed, sticking his tongue out at Paige whom was clearly the main instigator of this display. Looking around the room it seemed as though this was going to be a small intimate get together, just Mia and her three closest friends. Of course there was Paige whom was already making obscene gestures at Sam like an annoying kid sister. Beside her was the always shy and timid little white mouse girl, Selena Ruell. With quiet a slender build and no real curves to speak of, she at least had a perky behind and a pretty face Sam mused briefly before looking over at the last friend. The black pantheress stared intently at him with piercing golden eyes, always wearing that same soft knowing smile as if she knew something he didn't, never failing to make Sam feel uncomfortable around her, but she was a fiercely loyal friend to his sister so he put up with her.

"Hey Courtney..." Sam smiled politely to the feline as he shuffled on through to the kitchen to put everything away. Giving a startled yelp as he felt someone pinch his rear while bending over to put the drinks away in the fridge, turning about to be met by a grinning Paige. Sam for his part would just roll his eyes at her as she leans past him to grab a soft drink from the fridge behind him, though he couldn't help but notice how full and soft her breasts felt against his chest from being this close. He could even smell the faint scent of her perfume. Thankfully she left the kitchen as soon as she'd appeared, his pants feeling uncomfortably tight with the way her behind was shifting beneath her tight short and the swaying of her hips.

After taking far longer than should have been necessary to pack everything away, Sam eventually joined the girls in the living room and joined in the conversation, talking about college life and all the usual polite topics. Every so often Paige would throw him for a loop though, turning something he said into an innuendo. As much as he hated to admit it, that girl really knew how to push his buttons. When they were younger she never failed to get him riled up and angry, but now they were both older and consenting adults, she seemed to have found a new way to rile him up. Sam shifting uncomfortably in his seat as his pants once again became uncomfortable.

Thankfully time flies when you're having fun, and it was already starting to get dark out. Bidding the group a fond farewell, he headed upstairs to get ready to head out for the evening and leave the girls to do whatever it was girls did at slumber parties at this age. Standing under the hot shower and scrubbing himself down, Sam found his mind kept wandering back to Paige and how she was staring at him. Typical to how nature works, Sam felt himself getting hard again, thankfully this time with no uncomfortable tightness in his pants. His thick red rocket began sliding from his soft furred sheath, a soapy hand reaching down to give it a slow stroke as he groaned softly. Just then he heard a roar of laughter from downstairs, quickly snapping him back to reality.

"Dude, what're you doing! She's your sister's best friend, hell...she's like a sister to you too!" He thought to himself, with a growl he turned off the hot water and let the cold shock sober him up some. With his red length starting to soften and retreat, Sam climbed out the shower and was reaching for a towel when the bathroom door opened to reveal Paige standing before him.

"Oh, sorry...I thought you were finished showering. I needed to use the little girl's room" She almost purred to the stunned wolf, standing practically spread eagled before her with his junk on full display. Instead of blushing and closing the door however, Paige continued to grin at Sam as she closed the door behind her, turning the little switch to lock it. Again she broke out her sultry swaying hips as she closed the gap between them, her muzzle tilting up to kiss his chin as a soft hand reached down to grasp his retreating cock and giving it a gentle squeeze and stroke. "Always knew you were packing" the husky girl teased.

"Paige, what're you doing!? What if Mia finds out?" He hissed at her, not wanting to raise his voice and alert anyone downstairs of...oh god, what was she doing? Before he'd even finished speaking Paige was kneeling on the plush white bathroom matt and sinking her soft glossy lips down over his rapidly swelling length. Her time in the drum majorettes shone through with how dexterous her fingers were as they cupped and rolled his soft furred orbs in a hand. Her other gently tugging his sheath further back to let her lips and muzzle swallow more and more of him. Sam knew he should stop her, but damn she was good at this. With the towel quickly forgotten, his hands instead found the back of her head as he began bucking into her sucking maw. Little Paige, now a beautiful and attractive woman was clearly not new to sucking dick as she didn't even flinch when her lips began kissing at his knot as she swallowed his entire nine inches with ease. The entire situation was just too much for Sam and he felt his balls tuck up close against his body as his cock began to fire off messy ropes of his seed down the husky's throat, Paige for her part never stopped sucking and swallowed every one. She smiled up at Sam as she waited for him to finish cumming before she slowly pulled back with a wet slurp, giving his tip a little kiss before standing and heading towards the door, stopping just before she unlocked it and looked back over her shoulder at the panting Sam.

Her hands gripped her shorts and pushed them down over the curve of her behind and about her thighs, her fluffy curled tail lifting up as her fingers slipped into the cleft of her behind to spread her soft white furred cheeks a little and reveal her impossibly tight looking little tail hole. "I've been saving this for you...you can have it when you come home tonight and everyone else is asleep"

Even though he'd just blown a massive load down his sister's best friend's throat, Sam felt his cock growing at the sight before him, along with her offer. Nodding dumbly at the sexy husky girl, she unlocked the door and left without a further word, leaving Sam to dry off and get dressed. Feeling a little embarrassed and ashamed of what had just occurred, Sam gave the girls a quick farewell as he headed out for the evening. He'd almost thought he'd imagined the entire thing, at least until he caught Paige miming sticking a finger on one hand through a tightly looped finger on the other behind his sister's head. That sent the white wolf scurrying out the room before his blush was noticed, or worse, the bulge in is slacks.

All through the evening Sam argued with himself about taking Paige up on the offer, part of him didn't want to ruin their friendship with sex. But the more he drank and the less his logic played a part, the more he wanted to. It wasn't every day he got offered by a stunning young woman to let him fuck her in the ass, hell he'd never had any women ask him or even listen when he asked to. Looking down at his watch he noticed it was getting pretty late and he should probably make his way home before he got too drunk, already his head was starting to swim and his vision a little blurry. Despite common sense he would drive the short distance home, the journey uneventful save for a minor pothole or two.

Opening the front door Sam noticed it was oddly quiet, except for some low music playing in the lounge. The lights were off, the only light source was from a few lit candles around the room making it rather difficult to see clearly. Sam's nose twitched as there was an odd scent in the air, one which made his crotch twitch, but surely it couldn't be that? Looking into the lounge he was shocked to see a nude Courtney sprawled out on her back on one sofa, thighs wide with an equally nude Selena's passed out face pressed to her crotch. On the opposite side of the room was a familiar white furred body, Paige appeared to be burying her head under a large pillow while kneeling over the seat of the chair. Her thighs parted and fluffy tail still slowly wagging, along with her snug little pink slit on display. Still dripping from who knew how many climaxes, a thick black horse strap on lay in the harness on the floor between her spread feet, indicating someone had obviously used it to fuck the huskies brains out. Sam coughed loudly to see if anyone was conscious enough to register his presence, but none of the three girls so much as flinched. Looking around the messy room it was no surprise, they looked to have polished off all the alcohol he'd purchased for them, bottles and cans strewn throughout the living room. There were only three bodies in the lounge however, Sam didn't see Mia anywhere in this carnage and wondered if she'd gone to bed before it happened. Taking one last look at Paige's presented rear, Sam headed upstairs to see if Mia was up there. Sure enough as he peeked through the open doorway, Mia was curled up under her covers with her head covered under a pillow to block out the noise downstairs. Sam feeling oddly comforted that she appeared not to have partaken in the festivities before he headed back downstairs.

Once more Sam coughed loudly again as he entered the living room to see if he could rouse anyone, but still the girls remained oblivious to the world. The devil on Sam's shoulder yelling the loudest as it urged him on, guiding the white wolf down to kneel behind Paige. His fingers brushing up along her inner thigh before caressing her still slick slit, Paige responding with a soft intake of breath and a low groan. Her hips wiggled back against his touch encouragingly before a muffled "Sam..." was heard. Good, she knew it was him. Grinning as he quickly fished his stiffening length out, Sam firmly gripped Paige's waist as he ground himself against her, teasing his growing length between her thighs until his cock was at full mast, spitting his eagerness across her soft white cheeks. Reaching down and grasping himself by the base of his shaft, Sam guided his tip to the husky's hot little opening, nudging between her folds to line himself up before slowly sinking himself into the inviting snug heat beyond. God she felt good, already clenching down tight around him and grinding back onto his length as she softly whimpered his name into the pillow over her face. Sam held still for a moment, trying to calm down before he came too soon. Eventually he would be able to pull back a few inches before reversing direction, starting a slow and steady sawing motion as he stuffed that snug husky cunt with his thick red shaft. He could feel Paige getting hotter and wetter, rolling her hips back against his until there was a soft constant clapping sound fighting for dominance with the soft music. He was in heaven, Paige felt even better than he could've imagined around his cock, Sam rather thankful she wasn't a virgin so she could take him easily. But the churning in his balls soon brought reality crashing down around him, he was about to cum unprotected inside her, but he was too far gone to stop now.

With a low growl as he fought with himself to stop and pull out, a broad grin caught his lips as he remembered her offer earlier. Looking around for a brief moment, Sam was thankful to find a tube of something that would make for an adequate lubricant. Gently gripping and lifting Paige's tail up out the way, he carefully upended the tube and deposited a fair dollop of the apparently cold liquid square on that tiny pink pucker as Paige shivered with a little intake of breath. Using his thumb to gently massage it around the tight opening before pressing every firmer against the muscled opening, his thumb eventually slipping into Paige's behind being met with a soft drawn out "Saaaaam..." from beneath the pillow, along with a little wiggle against his digit.

"Good, she still wants this" he thought to himself as he steadily worked his thumb in and out of her, gently stretching that tight opening until she took his digit with ease and only minor resistance. Sam couldn't wait any longer, his balls were churning and needed release soon. Stroking the remainder of the lube along his shaft, the wolf guided his tip to the small indent under the fluffy white tail and began to push. With surprising ease he managed to sink the first inch within her relatively easily, though again she would gasp and utter another "Sam!" under the pillow. He halted for a moment to see if she'd tell him to stop or pull away, but she didn't and so he kept going. Gradually working himself deeper and deeper into her until his hips met her behind. Closing his eyes and biting back a growl from how hot and tight Paige's behind felt, he knew he wouldn't last long here. Slowly withdrawing his throbbing length to just about the tip, he carefully pushed back into that gripping channel. He wanted nothing more than to pound her into the couch, but with his size and how tight she was, thankfully he wasn't drunk enough to make that mistake. Not that it mattered however, after only a half dozen strokes Sam would feel himself boil over. Pressing deep into Paige's rump again, his thick knot forming and spreading her cheeks as he unloaded another heavy load inside her that night. His knees feeling week and bright lights bursting behind his eyelids from the intensity, nearly collapsing onto his behind from it. Very gingerly he withdrew himself from Paige, leaning over her to give a little tender kiss to the small of her back before heading upstairs. Briefly stopping in his tracks as he thought he saw a yellow eye watching him, but when he rubbed his eyes and looked again Courtney was still passed out.

With his head now much clearer after his climax, Sam thought he should at least say goodnight to the birthday girl before he went to bed. Sneaking into her room and gently lifting the pillow as he leaned down to give her a kiss on the cheek, his heart skipped a beat as Paige rolled over to smile up at him "I've been waiting for you, lover boy."
