It was about 6:30 in the morning when his phone started ringing, forcing the wolf to groan and roll over in bed, fumbling around on the nightstand. With a little bit of effort, he opened his eyes just far enough to see where the answer call button was, swiping across the screen with a thumb and flopping back onto the bed, holding it to his ear. "W'sup?"
"Daddy?" His ear twitched at the familiar voice, pushing him a bit further into wakefulness. "Daddy, it's Cindy, I, um... You know I love you, riiiight?"
"Cindy? Wh... What... Why are you calling at..." He struggled to sit upright in bed, glancing at the phone screen, "Fuck-me-it's-early-o-clock?" 
"Haha, funny you should say it like that..." She squeaked out, sounding nervous. "I...I need your help, daddy. How soon can you make it to school?"
He groaned, rubbing his face tiredly and forcing himself to move to the edge of the bed, sitting up fully. "I dunno, like... A couple hours? What's wrong? Are you in trouble? Are you hurt?"
"I'm not... Hurt... I'm just... I mmiiiight be in trouble? If you don't get here quick..." Again, the nervous not trembled in her voice, and her father struggled to hold the phone up to his ear with his shoulder as he started to pull on clothes.
"You need to tell me what's wrong, sweety, you're being really vague and I can't help you if I don't know what's going on."
"I... I ran out. I'm sorry, I was studying so much lately and I wasn't paying attention and I drank it all and now there's none left and the exams are today and I'm going into heat and I don't know what to dooooo!"
"Ran out? Ran out of what?" He paused, half way through pulling up his pants, his brow furrowed in confusion.
"Your cum, daddy! You gave me those Thermos full of cum because you KNOW how I get without a Feeding and I really don't like any of the boys here and I know you said it was supposed to last me until tomorrow after the exams because you were busy at work but now it's all gone and I'm so. Fucking. HORNY." Those last words were a mix between a growl and a desperate, needy moan, which made his ears perk up and his boxers start to tent out. He dropped the phone, struggling to pick it up and tug his pants up over the growing bulge in his shorts. 
"Well... Okay, but... Surely you can wait a little longer, honey, I know you get really frisky but it's not an EMERGEN-"
He was cut off by a long, soft whine and the sound of something falling over, making him stop moving again, straining to listen. When her voice came through the phone again, it was quieter, like she was far away. "Listen, daddy... Listen to how wet your little girl is..." And then came the very distinct, slick squelching noises that he KNEW came from something pushing in and out of a very wet, warm hole. "Please daddy... I'm going into heat... I NEED your cum... I can't sit through an exam like this... I can't focus, I can't THINK..." The noises got louder, faster, and the wolf licked his lips unconsciously, reaching down between his legs to try and find a comfortable way for his swelling cock to sit as it strained under his clothing.
"Okay... Okay sweetheart I'll... I'll hurry over, okay?" 
"Mmmmnnm... Yesss daddy..." She moaned in response, seemingly too lost in her temporary relief to notice she was still in call.
He couldn't bring himself to hang up either, rushing around to grab a jacket and his keys, mostly with one hand, making his way to his car and jumping in, putting the phone in its charging socket on the dash. Immediately, the hands free kicked in, filling the inside of the car with the lustful squeals and squelches of a girl enthusiastically playing with herself. He wasn't exactly lacking in enthusiasm himself, though in a different way... Speed limits -may- have been broken in a few places, turning a leisurely two hour drive into a 45 minute sprint. 
At some point during the drive, the call had cut out, but his daughter's cries were still echoing in his ears when he arrived at the school, parking up outside and sending a quick text asking where they could meet. What came back was short and simple - a classroom number, the word "HURRY" in all caps, and an attached photograph of a set of chubby and swollen outer lips, short black fur matted down with juices, that were spread slightly by two fingers to expose the sweet golden flesh within, slick and shiny with arousal. Before he closed the picture, his eyes caught on the tiny ruby clit piecing she'd gotten for her last birthday, remembering the adventure they'd had going to get it done... He wondered if she still had the outfit... 
Shaking his head quickly, he jumped out of the car and almost ran towards the school, slipping past the receptionist with a smile, a nod and a wink, hurrying down the halls to his goal.
He never actually made it to the classroom, however, as his left arm was grabbed suddenly, yanking him aside and into a small closet which shut behind him, plunging the room into pitch blackness. While his eyes couldn't adjust very fast to the sudden lack of light, his nose had no problem identifying who had pulled him inside.
"A broom closet, Cindy? Don't you think that's a little clicheooOHHH gods!" His words trailed off into a breathless moan as his daughter dropped to her knees in front of him, yanking open his pants with enough force to tear off the button and with one smooth motion, quickly forcing his boxers down to reveal his throbbing, rock hard member and engulfing it inside her warm, suckling maw.
Her long, wolfish muzzle was perfect for cradling his cock against her tongue, completely filling her mouth as she bobbed her head gently, tapping the head against the back of her throat. With her father already pent up from listen to her finger herself on the phone during the car ride, her maw was quickly coated in slick, warm precum, a treat that she gulped down hungrily, greedily, her eyes fluttering closed and her body shuddering in climax as her intense cravings were finally given some relief. Her long, broad tongue swirled over the twitching pole of fuckmeat between her lips, exploring every throbbing vein along its massive length that she knew so very well. Her hands moved up to tenderly cup and caress the churning, melon sized sack that dangled low beneath her daddy's dick, giving the hyperactive cum factories the loving attention she knew they deserved, hopeful that they could give her a nice full tummy of the cream she was so addicted to.
It didn't take long for her wish to be granted, the telltale lifting and tightening of her daddy's balls making her squirm in happy excitement. She pulled them up against her chin gently, pushing his shaft deeper, trying to get her nose against his belly, but she shouldn't have worried... She soon felt his strong hands grasp around the base of the horns on her head, using them like handlebars to hold her still while his hips thrust forwards, forcing his massive breeding tool into her throat, building up to a rhythm that saw him actively fucking her face like a happy, drooling sex toy, her gag reflex trained out of her long ago, replaced by a lewd sensitivity that pushed her over the edge over into a body shaking orgasm. 
No man could last long in such a warm, hungry hole, especially not when it belonged to their own sweet, sexy, cum starved daughter. With no reason to hold back, the wolf let out a low growl as he buried himself to the hilt in the maw of his little girl, her nose buried in his crotch fur making sure she could breathe in nothing but HIS scent for the long half minute it took him to unload, cumming in long, thick ropes straight down her throat, which massaged his length eagerly each time she swallowed. 
Her normally toned belly quickly began to swell, taking on a soft, rounded paunch as her father's seed filled her up. It was exactly what she needed, and her daddy knew it, feeling no small sense of satisfaction when he started to pull his hips back, rubbing the head of his cock against her limp, lolling tongue, painting the roof of her mouth with rich virile wolf spunk and driving her into yet another climax as the impossibly potent TASTE of him melted what was left of her brain into a puddle of useless, cum-addicted goo.
Finally pulling all the way out, he slapped his cock gently on her muzzle, stroking his shaft lazily to paint her panting face with the last few spurts of his orgasm, staining her black fur a rich white and draping in goopy strings from her long curly blonde hair.
"Thankshou daddyyy..." She slurred out drunkenly after finally swallowing enough seed to get some words out, starting up at him with an empty headed smile.
Staggering slowly to her feet, helped by her father, she moved around him towards the door, but found that her arm was still held firmly in his grasp. He smirked, face twisting into a predatory, wolfish grin. "Where are you going, sweetheart~? You can't possibly think we're done..." She opened her mouth but he cut her off before she could utter a single word. "-Spread-." 
The response in her was instant, the phrase more of a command than anything else, her body reacting in a learned and practiced motion to lean forwards, feet spread, tail hiked up high for balance, hands reaching behind her to grasp her asscheeks and spread them nice and wide. Her tail twitched as a shiver ran down her spine, her cunt juicing itself at the pounding it had been trained to expect in this position, honey running down her thighs in long glistening trails. "You still have to pay for waking daddy up so early in the morning..." Her father spoke teasingly, but there was a threat behind those words, and it made Cindy shudder in anticipation. 
His eyes had, by now, adjusted to the darkness of the closet, and he could see that his little girl was, in no uncertain terms, sexy as -fuck-. She was wearing laced up white stilettos with chunky soles, a short pleated navy skirt that right now was flipped up her back but couldn't possibly do more than barely cover her ass, and a lacy white high waisted thong that was so drenched in her pussy juices it may as well have been transparent. Her top was a button up blouse that had been cut high to expose her midsection, and a quick glance around her cum-swollen belly confirmed that her small perky breasts were practically falling out from under it. 
DAMN he loved this uniform.
"D... Daddy... I... Um... Ex...am...?" She struggled to form coherent thoughts, her head still hazy from gulping down so much cum, but to her credit she didn't even attempt to move from her provocative position. He didn't waste any more time, moving behind her and tugging her panties to the side, pressing the head of his cock against her dripping, twitching cunt. She gasped, tail twitching more, curling up over her back as she felt his hands grab her waist, but she didn't get the chance to try and say anything else as his very first thrust drove the wind out of her, along with any other thoughts she might have been having. 
He didn't bother starting slow, launching immediately into a rough, brutal FUCKING that made her whole body shake. Her face was pushed up against the closet door as she squealed in pleasure, tongue lolling out once more and eyes rolling up into her head, hands still dutifully keeping her asscheeks spread for her daddy. His huge, throbbing shaft seemed even larger than before, the nearly foot long spire of ebony wolfcock stretching out her pussy and ramming up against her cervix, which could barely put up any resistance before he pounded his way through it, claiming her womb, making her scream in a powerful climax. He moved his hands from her hips to her wrists, pulling them back, forcing her back to arch taught, breasts out, G-spot being brutalized with every thrust. Even through her sloshing belly full of cum, the bulge of his massive lupine cock could be seen every time he slammed his hips into her, bruising the back of her womb in a way that she knew would leave her a blissfully pleasant ache afterwards.
When she started to feel the gigantic swell of her father's knot begin to pound insistently at her already stretched pussy, she did manage to somehow squeak out a few words of weak, pathetic protest. "D...daddyyyy... I...I h h have to... Ex... Exam... S soon..."
"I know, sweetheart... You'll just have to go into them aching and gaping..."
She whined, embarrassed and thrilled at the same time. "B b but... If y you...nyaaAAAaaAHh!" She spasmed and thrashed, cumming hard in the middle of her sentence as he managed to SHOVE the huge bulb of flesh into her cunt and started rutting her like a wild animal. "P p peeeople w will h h heeaarr mmeeee..." In fact, their sensitive ears could already pick up the sounds of other students starting to walk down the halls, most likely heading to the same exam that she was supposed to be preparing for.
"Good... Let them hear..." He growled in her ear, fucking her HARD as he neared his climax, his hips smacking loudly against her ass, "If you scream nice and loud for daddy... Make sure everybody knows what you are... I'll give you a nice big belly full of cum..." He suddenly stopped, holding her still, and whispered cruelly, "Or I could stop... And just pull out... Find another willing hole to breed..."
That was too much for her, and she shoved back against her father desperately, bucking her hips, long tail wrapping around his waist to hold him in. "N nnnNO NO NO! Fuck ME daddy! Please please PLEASE fuck me, pound me like the little slut I am! I'm daddy's dirty little whore, your fucktoy, your eager hungry little cum bucket!"
He grinned, and like the good father he was, gave her exactly what she wanted... What she NEEDED. Her words got garbled into nonsense squeals as he got right back to fucking her cock-addicted brains out, her lips curling into a happy mindless smile, drool running down her cheeks, tongue flopped out as her loving daddy pounded her into a senseless mess. His hips pulled back hard enough to drag his fat knot from her stretched out cunt, but slammed it right back in afterwards, again and again and again... It took him less than a minute to drive himself to the edge, losing count of how many times his daughter came on his cock, squirting over his heavy full balls and over both their thighs, the scent of sex filling up the room to the point it was all either of them could smell. Letting go of her arms, her reached around her and grabbed hold of her tits, pulling her back against his chest, each of his powerful thrusts practically lifting her off her feet. With her hands free, she cradled her belly, most of the cum from earlier absorbed, making the obscenely lewd bulge of her daddy's cock much clearer against her stretched belly scales. Her fingers pressed against that bulge, squeezing, making herself even tighter, and finally forcing her father to tip over the edge entirely.
 He dropped his head back and HOWLED, knot firmly stuck inside a tight hot pussy, lodged firmly at the back of her womb, he came so hard that she could FEEL each spurt crash against her insides, visibly bulging out her stomach, GALLONS of the impossibly virile, thick, creamy Alpha wolf spunk flooding into her deepest, most sacred place, thoroughly claiming her womb, marking it as forever HIS. 
She dangled there, stuck on his dick as he just. Kept. Cumming. For endless minutes until her stomach was rounded out with what could have been triplets, if not more. Eventually though, he did let her feet rest properly on the floor, and gave her ass a hard, sharp spank to bring her mind back from the blissful dreamland it had fallen into. She jerked and shivered, blinking rapidly, but anything she might have said was cut off by the feeling of him pulling backwards, dragging his still swollen knot from her poor abused pussy with a loud, wet schlorp, cum -gushing- from the stretched out hole onto the floor at her feet, the thick gunk splattering noisily, sticking to her inner thighs. She could only let out a gutteral, whimpering moan as her jelly legs struggled to keep her upright, her body leaning against the door and sliding slowly down it, onto her knees. 
Her father squatted down slowly, turning her to face him, cupping her chin and tilting her face up, smiling warmly. "You're such a good girl, Cindy... Daddy loves you SO much..." She smiled at that, heart filling with joy that felt so good alongside the well-fucked bliss that filled her body. "Now..." He stood up slowly, and she found her vision blocked by a half-hard, still throbbing spire of glistening, cum-soaked obsidian cock-flesh. "Clean me up quickly with your tongue, and head off to those exams... I know you'll do great..." She didn't have to be told twice and immediately got to work, using her lips and tongue to thoroughly clean every single inch of her daddy's cock and balls, not wasting a single drop of cum... Except for all of it that she smeared into her face and hair every time she adoringly rubbed her face against his junk. He pulled out his phone, snapping a few choice pictures of her sensual worship, stroking her hair lovingly. "You're as smart as you are pretty.... And you do look SO pretty all covered in daddy's cum..."
Even with her mouth stuffed and bulging full of cock, the young girl beamed with pride at the compliments, reluctantly stopping only when the school started doing callouts for the exam to start soon. "Thanks daddy..." She stood up, stretching as high as she could to kiss him on the cheek, smiling warmly. "I love you~!"
"Love you too, pumpkin." He gave her an affectionate smack on the ass as she moved out of the closet, and grinned to himself as he noticed the slow river of spunk dribbling down her thighs from her still gaping pussy, her legs wobbling and large belly sloshing as she made her way down the hall. He really was the luckiest father in the world...
