Chapter 1

"Please please please," his daughter begged, literally on his knees in front of him, staring up at him with those big kitten eyes of hers.

But James remained adamant, his arms crossed in front of his chest. "It's not right," he insisted. "It doesn't matter how much you ask, I am not_cooking up a 'love potion' to make some guy ask you to the prom. I mean, what's the difference between that and a date rape drug!" She was his _step-daughter, actually. Adopted. A brown and white tabby. Their stripes were the only thing they had in common. He was a zebra, and stuck out like a sore thumb at any social gathering with his stripes. Sometimes it seemed like they didn't have any sense of morality in common, either. Just because he was one of the best bio-engineers in his field didn't mean he was going to make some kind of 'love potion' for her! It was well within his abilities, of course - just a matter of the right hormones - but decidedly not the sort of thing his abilities should be used for.

She grabbed his hands, preventing him from turning away and going back to his work. "Please! You have to do _something!_I could have a real chance at being Prom Princess! You know how big of a deal that is! But I'll never be able to if I don't even have a date. And everybody else is already taken somehow. Please! I don't know what I'll do if I don't have a date - my whole prom will be ruined! And I only get one!"

Hm... Well, he certainly would not be concocting a date-rape drug for her ... but what if there was another way? It was a crazy idea. And it very well might not be within his abilities. But the sheer challenge of it was tempting.

"I think I might have another solution," he told her. "Let me go to my lab and see what I can do. No promises, but I think it might actually work..."


It had taken the better part of a week to perfect the formula. And most of a day for the effects to take hold. But it was finally complete! And just in time, too. Amelia's prom was later this very day. He'd barely finished this on time, and he still had a lot to do.

In the bathroom mirror, he took stock of his results. Yes, the de-aging serum seemed to have worked. Gone were the slight wrinkles around the edges of his mouth; gone were the graying and frazzled strands of his mane; even the slight paunch that had developed around his belly had smoothed out into a sleek and chiseled set of abs. He could easily pass for a zebra stallion in his late teens now. He could fit in with the eighteen and nineteen year old crowd at the prom. But that wasn't enough. Too many of them knew Amelia and knew her father was a zebra. They might suspect something if he looked like this. Thankfully, that bit of disguise wouldn't require complex bio-engineering. It was a simple matter of cosmetics. The bottle of black hair dye on the countertop would turn him from a black-and-white striped zebra to a simple black stallion. The tail extensions and mane conditioner still in the shopping bag next to the counter would complete the look. Once he was done, he would certainly pass as a young horse ... and he'd finally be able to give his daughter the prom date she so desperately needed.


James ... or Jimmy - he should really already be getting used to calling himself Jimmy Kixx now - knocked on his daughter's bedroom door again. "Are you almost ready, honey?"

"I'm not going! What's the point? They're just going to laugh at me!" The voice on the other side of the door sounded inconsolable, as if she'd been sobbing for a while now.

He was more glad now than ever that he'd taken the drastic measures he'd resorted to. She really _did_need this desperately. But was she decent in there? Did she have her prom dress on yet? Hopefully she hadn't done anything crazy like tearing it to shreds or something. He touched his hand to the doorknob, then thought better of it. The last thing he wanted to see was his step-daughter still in her underwear or something. And she certainly wouldn't appreciate being walked in on if she was in such a state. No ... better to play it safe. Try to entice her out.

"I think I may have found a date for you," he said, hoping he'd put the right amount of enticement and confidence in his voice. Could she already hear the slight difference his more youthful body made in his voice? It was only a temporary effect, unfortunately, but he was already beginning to get used to it.

"It's too late now!" she cried. "The prom is tonight! Even if you did make something, I'd never be able to use it in time..."

Steeling himself and hoping for the best, he reached for the doorknob again. He could only hope that she wouldn't be naked in there. Almost not daring to look inside, he opened the door.

Amelia was not_naked, thankfully. She was in the frilled indigo prom dress she'd picked out, crouched at the foot of her bed with her head in her hands. When she heard him come inside, she slowly looked up ... and then recoiled in shock, backing away from him. "Who are you?" she shouted, raising her arms as if to ward him away. But then she looked more closely, blinking and staring at him. "Wait... _Dad?" Her mouth fell open in shock.

He smiled. "What do you think, honey?"

Amelia's eyes were still wide, darting all over his body. He'd already dressed up in the formal suit he'd prepared, an elegant black number that he knew would be striking on his now black body, not to mention the perfect tailoring to show off his more youthful body. He posed a bit, showing himself off to the best possible effect.

"What did you do to yourself, Dad?"

"Don't worry, it's only temporary." He went over to her and held out his hand. Thankfully, she was recovering enough to take it and let him lift her to her feet. He grinned widely. "And don't call me Dad, okay. I'm your boyfriend from the next school district over - Jimmy Kixx."

Her face scrunched up. "Jimmy Kixx? Seriously?"

"What? That's a cool name."

She shook her head a little. "Okay, whatever. We'll have to hurry if we're going to get there in time."

Chapter 2

Jimmy Kixx screeched to a halt in the local hotel/convention center parking lot, enjoying every bit of his new persona and the cool little convertible that came with it.

But Amelia just shook her head at his driving. "Where'd you even get this old thing?"

"This?" He patted the leather-wrapped steering wheel. "This isn't old, it's a classic. And I borrowed it from your Uncle Steve. You know he's got that collection and all. I pulled a few strings, called in an old favor. I'm not about to bring my daughter to her prom night in some boring old minivan, am I?"

She just rolled her eyes. "Nobody cares what car you have. Come on. They're probably starting already."

Despite the encumbrance of her dress, Amelia made quick time to the entrance, forcing 'Jimmy' to hustle just to keep up with her after locking the car and putting the roof back up. Which is why he didn't notice the skunk girl just outside the door until he was only steps away from her. The girl was on her knees right there in the doorway, looking up at him with a hopeful expression, her eyes sparkling a little in the late afternoon light. Her prom gown was already quite deeply cut in the front, but even so, it was pulled down almost to the point of exposing her generous breasts to the world. "Feel like a blowie?" she said enticingly ... but with a little tinge of desperation in her voice.

Amelia took hold of his hand, dragging him onward when he was too shocked to move. "Come on," she said. "Don't put your dick in Raylee's mouth. She's the school skank."

While he could completely believe that, given what he'd seen so far, what he saw when he actually _entered_the school made him wonder if it was really the truth. By this school's standards, maybe giving out free blowjobs at the entrance was relatively chaste! The entire inside of the convention space was basically one huge orgy. Everywhere he looked, he saw nothing but barely-legal teenage bodies in various states of undress and in various stages of passion with one another. A fox girl leaned back on the catering table, pouring punch down her naked body to be lapped up by the three dogs licking at her crotch. A skinny doe knelt in the corner, sucking a short raccoon boy's cock. When he turned to look the other way, he found himself staring at a couple of guys - a lion with a slicked-down mane, spewing cum out onto the dance floor as a tiger penetrated him from behind and gave him a reach-around.

"Hey!" The jerk on his arm from Amelia pulling at him snapped him out of it. "Yeah, it's not some lame prom like when you grew up," she said. "Try not to act like an old fogey, alright? Don't embarrass me."

She dragged him deeper into the writhing mess of eighteen and nineteen year old dancers and revelers, not giving him even a moment to pause and take it all in. He accidentally bumped into a pig girl's ample - and very bare - behind as she danced. His rubber-shod hooves slipped in a puddle of something he'd rather not think about, almost sending him sprawling onto the floor in the middle of it. A coyote girl with pink-dyed hair openly groped his crotch as he walked by. She said nothing but "Mmm! Nice cock!" by way of apology. Of course, his cock had been slipping out of his sheath a bit, given all that was happening around him. It was inevitable that something like that would happen. And being the zebra he was, he was of course well-endowed. The bulge was definitely showing ... and a lot of these teenage kids - both girls and boys - were eyeing it up appreciatively.

"There's Betty," Amelia shouted over the music. "She's my best friend, so be cool, alright?"

Before he knew it, he was face to face with a donkey girl just a little shorter than he was. She made up for her dull grey coloring with a blinding fuchsia dress with quite a short ruffled skirt, and her long ears were decorated with matching fuchsia bows.

"This is Elizabeth Quince, my friend Betty I've told you so much about," Amelia said. "Betty, this is, uh, Jimmy Kixx, my boyfriend from the next school district over."

Betty looked him up and down, licking her lips a little. "Well, Amelia hasn't told me all about you..." She elbowed Amelia. "He's cute!" And just like that, as casually as if she was shaking his hand, she lifted the front of her skirt, revealing ... nothing. Well, revealing quite a lot, actually. Most importantly, revealing that she wasn't wearing panties of any sort underneath. Her dark grey pussy lips were already shimmering wet in the moving lights of the little dance hall, framed between her nice and shapely thighs.

Jimmy stood with his mouth hanging open. What was this? He actually had heard his daughter talking about Betty before ... but he had never expected to meet her like this.

"Ugh, come on, Jimmy," Amelia said, reaching for his pants. She unzipped him and pulled his cock out, blatantly touching it as she did so ... as if it was no big deal. "Don't be rude, introduce yourself!"

When Amelia shoved him toward her best friend, there was just nowhere else for his stiffening cock to go. It slid right between Betty's already-slick thighs, making him gasp a little ... both in surprise and from the way it felt. When was the last time he'd felt like this? Certainly not since his wife had left... But that wasn't the end of it. Not even close. Betty reached down, stroking his cock a little as she moved it into position. She raised herself up on her tippy-toes, flexing her hips to get the angle right ... and just like that, his tip was inside her. He moaned at the sudden and unexpected warmth of having the head of his cock inside a pussy once again.

He turned his head to ask his daughter what she was thinking, pushing the two of them together like this, but Amelia was already making out with a couple of well-toned buck deer in letterman jackets ... and nothing else. Even as he watched, one of them bent her over toward the other. While the first buck started pulling up her long skirt, the other skipped straight to pressing his long red cock deep into Amelia's mouth.

Wow. Prom really wasn't like he remembered...

At this point, there was nothing to do but give in and go with the flow. With one hand, he grabbed Betty's nice firm little breast through her dress ... and from the way he could feel her nipple through it, he was pretty sure she wasn't wearing a bra, either. With the other hand, he reached around behind her slim waist, pulling her close against him. Pulling her close like that helped his cock slide deeper inside the teenage girl. She let out an almost bray-like moan as his medial ring entered her. And he didn't stop there. He didn't stop until he'd lodged the entire length of his cock inside his daughter's best friend, his sheath pressing against her pussy lips. It was a bit of a stretch for the smaller donkey girl, but as a fellow equine, she was able to take it, all of it ... even though his tip must have been somewhere even higher inside her than where he was grabbing her waist.

Betty tucked her face in close to his neck, holding her hands tightly against his back as she gave tiny, whimpering little breaths. The slightest movement of his shaft along her inner walls made her whole body quiver ... but he didn't stop. If this was how the prom was going to be, then he'd play the game. It was good to be young again. He hadn't felt this randy in years. Already, he could feel his tip flaring inside this supple young donkey, and thanks to his own heady rush of hormones, he didn't much care about the lack of any condom. He was going to breed this jenny, and he was going to enjoy it.

Amelia seemed to be enjoying her deer guys just as much. Who _were_those guys, anyway? Just some random jocks from the football team, or did she know them? Either way, they sure seemed to be enjoying themselves. The one behind her held her hips tightly, absolutely _railing_her from behind. The one in front wasn't much gentler, fucking Amelia's face roughly, both of his hands full of her dark hair. How much time had she spent fixing her hair just to have it manhandled by this buck?

It wasn't as if she was suffering, though. In fact, given the way her back was arching and her hands clenching tightly against the buck's thighs... Yes! There it was! He gaped at the sight of his daughter's blatant orgasm, at the way she moaned around the buck's cock, at the uncontrolled spurt of liquid from between her legs. Such an intimate moment. Something a father should never see his daughter experiencing ... adopted or not.

And yet, he couldn't deny that seeing it made his cock surge harder inside Betty. She sure felt it - she gasped, biting the side of his neck as her fingernails raked his back through his coat.

It was a foregone conclusion. No other way that this could end. Hilting as deeply as he could inside his daughter's best friend, his raging flare pressing tightly against the entrance to her waiting womb, Jimmy came hard. His cock spouted like it hadn't in years. He couldn't see it, since every last drop went toward filling the young teen's womb, but he could feel_it. It never felt like this when he jerked off. Was it because of his now-younger body, or just because he'd gone without a good rutting for so long? Pulse after pulse throbbed through his cock, each one pumping a prodigious new gush of cum inside the young girl, sparking _her_into orgasm as well. Her pussy clenched down around his shaft in almost perfect rhythm with the pulses running through his cock ... as if her body was trying to draw as much out of him as he could possibly give. If she wasn't on the pill, if there was _any chance of pregnancy, then it was a sure thing. The poor girl had to be absolutely stuffed by now, and he was still going! He couldn't bring himself to care, though. He was overcome by the primal instinct to breed this young jenny - consequences be damned!

Slowly, breathing heavily as he did, Jimmy slid his now-spent cock back out of Betty's still-quivering pussy. It snaked its way wetly out, the veins along its length glistening in the ever-changing lights of the room. Betty's skirt fell back into place before he could see the mess he'd made, but he did see fat white drops falling down below the skirt, blotching her thighs and splattering on the floor.

Amelia came up next to him, nuzzling his cheek and giving him a little kiss there. Wait - had he really just been kissed by his own daughter? Okay, yes, she'd touched his cock a moment ago. And, of course, he was supposed to be acting like her boyfriend. But it seemed like they were crossing uncrossable lines faster than he could even count them.

She wiped something white off of her lips, then looked out onto the dance floor. Scowled_out onto the dance floor. "There she is," she said, pointing to a pure white cat dancing her heart out, quite nude, to the great entertainment of a dozen guys around her. Amelia made a face of utter contempt, all but spitting on the floor. "That's Priscilla Norton. She's trying to be Prom Princess, and she'll probably manage it, too. Just look at the way all those guys are staring at her. Those are all _votes."

Jimmy nodded, even as he helped Betty to the floor. The now-exhausted donkey girl just needed a moment to rest ... and to let her pussy recover as his cum leaked out.

"She's going to be Prom Princess for sure ... unless somebody does something about it."

The look Amelia had given him was unmistakable ... but also confusing. "Uh... You want me to do something about it?"

"Duh!"

"But what can I do?" He held his hands up helplessly.

Amelia reached down and grabbed his still-slick and wet cock. It was already starting to recover its stiffness - the benefit of youth. She wiggled it in front of him. "Figure it out, Jimmy."

Chapter 3

Priscilla bathed_in all the attention she was getting. It was like a sweet, syrupy ambrosia that she swam through as she danced. She was the hottest, most desirable girl in this entire dance, and she knew it. The guys watching her knew it. Their envious girlfriends knew it. _Everyone knew it. And once she had that Prom Princess tiara on her head, it would be absolutely official. She was unstoppable. A force of nature. A thing of beauty. There wasn't anyone alive her graceful movements and perfectly shaped slender body couldn't entrance.

She danced her way close to a shy looking raccoon. Not a word to him. Everyone knew he didn't even deserve to be noticed by her. And yet she leaned in close, almost kissed him, brushed her hands down the front of his body, almost touching the little bulge of his obviously erect cock.

Yes, that was another vote for her, she thought as she danced her way away, swaying her hips in a way she knew was sure to mesmerize everyone behind her. That raccoon would be masturbating to the thought of her for years, and his vote for her might as well already be in the ballot box.

As she turned, though, she found someone else staring at her in a much different way. This wasn't the uncontrolled lust and need of the others. He was staring through her as if he already knew her soul's darkest secrets and didn't care. A big black stallion with a powerfully built frame, a fantastic black suit complete with black shirt and black tie ... and a positively _gargantuan_black cock, already hanging out of his pants. Well, it wasn't unusual in the slightest for guys in this prom to be so undressed. What _was_uncommon was the way he was looking at her, the way he was coming toward her without the slightest break in his stride, his cock swinging in front of him. She suddenly felt small, and she had the uncanny feeling that she was just a little girl - little more than a kitten - soon to be taken to task by a grown adult over what she'd been doing. A ridiculous notion, of course. She was just as old as he was. Probably older, since she was nineteen and most of her classmates were still eighteen. But she couldn't shake the feeling. Something about the depth his eyes, the way he looked at her.

She forced herself to continue her dance, though. He was just another teenage boy, and she knew how to handle teenage boys. Light on her feet, she pranced next to him, teasing him, brushing her hands over his body as if enticing him to touch hers as well. Soon, she'd have him begging for more, another vote for her, another guy hanging on her every--

He grabbed her wrist. It yanked her instantly to a halt. She stared down at his implacable hold on her, and before she could even think to protest, he used the leverage to spin her around, facing her away from himself. His other hand pressed against her back, pushing her, bending her over.

No. No way... He couldn't be about to do that could he? No boy here had the sheer nerve to--

Something pressed against her pussy lips. Something huge. Something hot. Something rapidly hardening.

Oh yiff! Oh yiff! He was too big, it would never fit, it would never--

Priscilla squealed_as the already slick tip of his cock spread her pussy lips open and squeezed inside. Where had it gotten so wet and slippery? Whose juices was he smearing inside her pristine pussy? It didn't matter. A moment later, she was _glad he was already slickened, because how else would she even survive_the way his massive cock was stretching her from the inside? He'd only given her a tiny fraction of what he had, and she already felt like she was at her limit, ready to burst. Felines weren't exactly known for being well-endowed, and her body was sized to match, not for _this long, thick monster invading her body.

Oh, the sheer sensation_of it, though! As he pulled back for another little thrust into her, she could feel the dam breaking, her resistance giving way. _Already?_No guy had ever gotten her off this quickly. It wasn't possible! And yet, there it was, the unmistakable rush of orgasm overcoming her, making her scream her lungs out in front of all these other people watching, mewling like an alley-cat in heat as this mysterious stallion she'd never met before simply _dominated her ... owned_her. Every last little bit of her pussy was his now, absolutely straining to the limit just to accommodate what he was doing inside her. It felt almost as if her entire _body belonged to him. The fullness in her lower belly was almost unbearable ... and yet, she couldn't quite decide if that was from the discomfort of being stuffed so full or from the heady pleasure of every last bit of herself being stimulated by each little motion he made inside her. The head-spinning, dizzying rush of orgasm tipped the scales toward the latter.

He wasn't done yet, though. Not by a long shot. He'd only just _begun_to fuck her, and he showed no sign of slowing down just because she was screaming and her pussy was clenching down on him like mad.

The stallion tried_to push deeper inside her, but she simply had nothing left to give. Even though the pain of his tip bashing against her innermost barrier was more than overwhelmed by the pleasure of being so brutally _taken, there was only so much her body could offer him. She hadn't even come close to taking his medial ring, leaving more than half his cock untouched.

Thankfully - for her ability to walk in the future - he seemed to quickly get a feel for her limits. And when he started thrusting inside her in earnest, he did so with small thrusts in and out. He was not gentle, but he also didn't bash her womb to the point of bruising, either ... even though she got the sense that he could. He easily_could. Even still, though... As considerate as he was being, he was still an enormous horse, and she was still a slender cat. She _knew_she'd be feeling aches from this fuck for weeks to come, and yet she couldn't protest in the slightest. The rippling motion of his shaft against her inner walls touched _every part of her, all at the same time, more thoroughly than any guy had ever done to her before. It was like her orgasm had never ended, as if she was still squeezing down hard, the explosion of pleasure still burning deep inside her belly. She could already tell that nothing else would ever be enough for her again. Every other guy she'd ever been with - even the most skilled - seemed like mere foreplay compared to this.

The hand that had been pushing on her back now grabbed her tail, something she'd normally never tolerate, but now she couldn't bring herself to say a single word about. She could feel the thickness of his girth even between her ass cheeks, where it rubbed either side of her before plunging into her. She felt like she was wrapped so tightly around him that she might as well call herself a condom. Condom! Had he been wearing one? She sure hadn't seen any! He ... he wasn't going to cum inside her, was she? She couldn't get pregnant right here in front of the entire school!

It didn't seem like she had much of a choice in the matter, though. He wasn't stopping. And her traitorous body kept overwhelming her with the pleasure of being so roughly used. She couldn't bring herself to want him to stop. She wanted more. She needed more.

Before she knew it, she was cumming again. Her legs buckled as she lost all control of herself. Nothing mattered but the rhythmic pulsing of her pussy against his still-thrusting cock. She tumbled to the floor, planting her face against the messy, cum-stained surface, unable to hold herself up in the slightest. Only the stallion's hand on her hip and his cock inside her kept her from going completely prone. She was lost to him now, putty to be molded, a cocksleeve to be used and discarded. She could barely keep her eyes open through the incredible rush of orgasmic hormones swimming through her head. It felt almost like falling asleep ... except it was the most blissful sleep she could imagine.

The stallion didn't stop using her. He didn't pause in the slightest. He seemed perfectly happy to fuck her face down, ass up right there in front of everyone, plowing her pristine white face into the dirty floor.

More than happy, actually. He ... he was getting even bigger_inside her! What the yiff? It was impossible! Doubly impossible! How could he get any more enormous than he already was? How could that possibly fit inside her already-straining pussy? Yet she couldn't deny the feeling of him swelling even bigger at the tip at the ... the _flare! She remembered one of her friends raving about the wonders of horsecock, gibbering mindlessly on about how wonderful the flare was. At the time, Priscilla hadn't seen what the big deal was. But she understood now. Oh goodness. The sheer size_of that thing inside her! It felt three times thicker than it had been before, to the point where she felt stretched around it like a balloon. With one trembling hand, she touched her own belly, not ready to believe ... and yet there it was. A _huge bulge in her lower belly, moving in time with the stallion's thrusts. She really was stretched around him like a balloon!

That turned out to only be the beginning, though. With a savage snort, the stallion hilted himself inside her. Apparently, he no longer cared about the limits of her body - he rammed that humongous flare right up against her womb, smashing it into submission.

She knew he was close. Knew she was about to be bred like some common farm girl in front of the whole school watching. She should have cared. What was happening inside her pussy should_have been agony. But she didn't care. And all she felt was the purest, most blissful, most mindless pleasure she could have ever imagined. _More than she could have ever imagined.

Priscilla absolutely lost it_as the big stallion came inside her. The inner walls of her pussy clenched helplessly around his cock as it spewed inside her, his cum streaming into her in long, continuous pulses. Each one felt like it would never end. And she didn't _want it to end. Because each burst of heat deep inside her sent her off yet another cliff of orgasm, into a deep chasm of pleasure she felt she'd never be able to crawl out of ... not because she couldn't, but because she'd never _want_to. Her belly pushed against her hand as it expanded, filling with his endless cum. Already it was swollen as if she was pregnant and showing, and it didn't seem like it would stop anytime soon.

By the time his orgasm slowed to a stop, her belly was huge. Far more than if she'd eaten a feast of a meal. If she walked around town like this, people would be asking her when she was due. If she could even walk at all. She sure couldn't feel her legs right now. And if she could take so much as a single step, she felt as if she'd _slosh_her way off-balance and simply fall over. Even as the stallion stopped pumping his virile seed inside her, her own orgasm didn't cease. It was as if she was stuck in a state of permanent bliss and the only escape was...

Well, the only escape was the inevitable collapse. She could already feel it coming. The dizziness, the blurriness around the edges of her vision. She'd already taken more than her mind could accept, and she was crashing fast. When the stallion pulled out of her and let her go, she flopped flat to the floor, only dimly aware of the small splash of cum fountaining out of her thoroughly used pussy.

The last thing she was aware of as she faded out of consciousness was that same raccoon boy - now without his pants - working his way around behind her, kneeling down, and inserting his cock into her gaping and still-oozing pussy. She scarcely felt it. After the massiveness of the stallion's cock, the raccoon's small endowment was all but imperceptible. Her world went fully black as the little raccoon started humping away...

Chapter 4

Amelia grinned to herself as she watched Jimmy - her own dad in disguise - make an absolute wreck of Priscilla Norton. Oh yes. _That_would show her. Only a few hours ago, Amelia had thought that she was ruined. She'd thought that Priscilla stealing her boyfriend and prom date was sure to take away any chance of becoming Prom Princess.

But just look at Priscilla now. Drooling on the messy floor as every loveless loser in the senior class finally had their way with her. She'd_never_ be Prom Princess now, and that seriously increased Amelia's own chances.

It still wasn't a sure thing, though. Far from it. Amelia wasn't the only girl in the senior class, after all! And everybody_wanted to be Prom Princess. Even Raylee, that skunk still giving out blowjobs at the front door. She needed to do something more, to make sure everybody here noticed _her and not some other girl. And, of course, it couldn't be more obvious what she needed to do. Who_she needed to do. He was walking back toward her now, carefully stuffing his well-used and very wet cock back into his pants. So _big... could she really do it? Well, she had to. That's how she'd show everyone here that she was better than Priscilla. That was her key to the Prom Princess tiara.

The thought of being fucked by her dad_was distasteful, of course. But nobody here knew he was her dad. They all thought he was her new boyfriend. If she didn't ride his big horsecock at some point tonight, then everyone would be wondering why she wasn't doing it with him. They'd be wondering if she even _could do it with him, after what they'd seen him do to Priscilla. Honestly, she wasn't sure she could_do it. She'd known that zebras - and zebras pretending to be horses - were big, of course ... but she'd never suspected they were _that big. Even after zipping his pants up, 'Jimmy' still had a pretty huge and pretty obvious bulge.

"So, not bad, huh?" he said to her as he came close enough for them to hear each other over the music. If he hadn't said it, it wouldn't have mattered. It was written all over his face. He was awfully satisfied with what he'd done with that new and younger body of his.

Would he be feeling younger enough to recover quickly and get that huge cock of his up for the third time in a row, though? Well, only one way to find out. She could always suck him a little if he needed some help. And besides, maybe this would be a little easier if he wasn't completely hard, right?

She came up to him, and without warning, she stood up on her tip-toes, reaching around behind his neck and pulling him down into a kiss. No little peck this time. Full on the lips, even slipping him a little tongue. She needed to know he'd be ready for what came next.

And he _did_seem to respond to her kiss, after a moment of shock. He even reached around her waist and held her closer against himself. She could feel the bulge of his cock against the front of her dress. Goddess, he was huge!

As the two of them separated from the kiss, still holding each other, she looked up into his eyes. The fur dye and the mane treatment hadn't changed those, and neither had the rejuvenation serum he'd cooked up. Those were still her dad's eyes. So weird. And yet, she couldn't help but feel like there was a tiny part, somewhere deep inside her - a part she'd never truly admit the existence of, even to herself - that was kind of into it. Steeling herself for what she was about to say, she forced herself to go through with it. She had to, if she was going to be Prom Princess. "There's just one more thing I need you to do..."

Jimmy looked at her a little skeptically ... but also with a gleam of anticipation in his eyes. He was already starting to expect something sexy. Had the kiss clued him in to what exactly she wanted?

"Come up on stage with me."

"On stage?" His skepticism grew. "What are we going to do on stage?"

She didn't bother with an answer. If he couldn't figure it out yet, he surely would soon. She took his hand and dragged him toward the stage.

The band on stage was doing their best. Honestly, they sounded pretty good, considering each and every one of them had their dick or pussy in the mouth of one of the enthusiastic students. She couldn't fault them for stuttering or missing a beat here and there ... especially as the tomcat lead singer came into a cute otter boy's mouth with only a slight off-pitch warble to the extended "looove" he was belting out for the dancing crowd.

It was a pretty low stage, easy enough to step onto. This was a convention center, not a concert hall. So there was no reason to worry about finding the steps onto it. Even in her dress and heels, she was able to step up on top of the stage without much trouble.

Dragging Jimmy up behind her wasn't as easy. He seemed to understand what was about to happen, and he was obviously still pretty reluctant about it. And, unfortunately for her, he outweighed her by quite a bit. That serum had even been able to slim him down somehow, but he was still bigger and taller than her, and he did not want to go on stage ... at least not yet. No matter how much she tugged, he wouldn't step up there with her.

Fine. She'd have to _entice_him up. Shouldn't be too hard. She knew what she had to offer, and she knew that no horny guy could resist it for very long ... not even dear old Dad.

Trying to make sure she didn't think about it too much, Amelia lifted the front of her skirt in front of Jimmy. Yes, it was best to just think of him as Jimmy ... and not anything else. When that_so-obviously caught his eye, she knew she was on to something. She'd have him up on the stage with her in no time! All she'd shown so far was a bit of her striped legs. But now that she had his attention, it was time for more. She hiked her skirt up farther, watching closely for his reaction as she did. A lot of her fellow students were watching now as well, but she paid them no mind. What was important was what _Jimmy did when he saw ... the tiny, red crotchless panties she was wearing under the skirt.

His jaw dropped. His eyes went wide. Oh, these panties had been worth every penny! It was basically like wearing nothing at all under her skirt ... and yet, in a way, it was so much more provocative.

She wasn't about to stop there, though. If she wanted to go through with what she was planning, she'd need the whole senior class to see it. To know exactly what was happening. And that just wouldn't work if her frilly dress fell back into place in the middle of everything. So she kept going, pulling it up and up. Thankfully, it came off pretty easily that way.

A moment later, she stood on the stage in front of Jimmy and everyone else, completely naked except for her crotchless panties and the long, elegant detached sleeves of her dress. No point in taking those off. Nobody was jumping at the chance to see her arms, after all. And they still looked quite nice, even if they didn't match the red color of the panties. She held her breasts, cupping them and pressing them upward to show off to the crowd ... to show off to Jimmy. Her chest wasn't that incredibly endowed or anything, but she had enough to work with, and it was certainly getting her plenty of attention.

More importantly, it was getting Jimmy up onto the stage with her.

He reached for her body, his hands trembling like a virgin. It _was_a really special and new thing for him, she supposed. A major line he was just now crossing. And she wouldn't let herself think about that any more than she had already. She might not be able to go through with this if she let herself get distracted with who he really was underneath that dyed fur and fake youth.

Amelia only let him touch her for a moment, purring as he ran his hands up and down her slim belly, as he reverently held her modest breasts, as he reached down to roughly grab her ass. She stopped him then. That was quite enough of him being rough and taking charge! If she let him do that too much, she might end up just like Priscilla! Instead, she spun him around, pressing him backward toward the band ... while also sticking her foot out to trip him up.

It was a bit of a dirty trick to play, but it was effective. One muffled cry later, her da-- Jimmy was sprawled out on the stage, flat on his back. Right where she needed him.

She quickly straddled his body before he could get up, which pretty effectively prevented him from moving at all. And she sat facing away from his head. Reverse cowgirl wasn't exactly her _favorite_position, but she figured it would be better for both of them if she wasn't looking into his face the whole time, constantly reminding herself - and him - of their true relationship to each other. Besides, it would be better if she was facing the crowd for what came next.

What came next, of course, was sucking Jimmy until he got hard enough to go for another round and then...

But wait, no... That bulge of his had gotten even bigger. He couldn't already be hard, could he? Moving fast now, she unbuttoned and unzipped him again. His cock practically sprang out at her, finally freed from the tight confines of his pants.

Wow... She reeled for a moment at the thought of what that meant. Jimmy, her - no! she wouldn't think about that! - her boyfriend from the next school district over was already hard, just from looking at her and touching her a little. Her, his own - don't think about it! Did that mean he'd always_wanted her? She'd thought she'd seen him glancing from time to time, but she'd always thought that was just a normal male thing. A habit he could hardly avoid. But now she wondered if it might be something more. No! Stop wondering! Stop thinking about _anything and just do him!

She forced herself to move on. There was no use making this weird. Weirder than it already was. Besides, him being already hard just made things easier for her, didn't it? She wouldn't have to spend any time sucking him firm when he was already so throbbingly stiff for her...

There were a couple isolated little cheers from the crowd as she lifted herself up - way_up - where she could actually press Jimmy's tip against her pussy. Goodness ... when had she gotten so wet? The very tip of his cock slid so easily against her slit... Well, she was just reacting naturally, as any girl would when faced with such a magnificently huge cock. Nothing more than that. And more than most girls her age, she knew _exactly what to do with such a lovely cock right beneath her.

Okay ... the very beginning was always the hardest. Amelia had taken big boys before. Not this big, but she knew how to handle herself around one. She forced herself to keep a brave face - a lewd and lascivious face - for the crowd as Jimmy's cock slowly spread open her pussy lips and squeezed inside. Damn_he was hard! She almost wished he'd been a little less turned on for this. Then again, what could she possibly do about that? Better to focus on what she was doing. And what she was doing was absolutely filling herself to the _brim with thick, meaty zebra cock. No, _stallion_cock. Stallion! No zebras here, only a lovely black stallion whimpering a bit behind her as he felt her tight inner walls squeezing the upper few inches of his cock.

Amelia gave a little whimper of her own as she sank down deeper onto his cock, though she did her best to hide it. Already, she felt stretched to her absolute limit, and she'd barely even touched his medial ring yet. She couldn't let the crowd of fellow students know just how much this was affecting her already. She had to make it look easy, make it look like she could do everything that Priscilla couldn't.

But could she? Yes! She would. She had to!

Taking a deep breath, Amelia shoved herself down. Just as she'd intended, his medial ring entered her pussy. Not as she'd intended, his huge tip entered her womb! It _hurt!_Goddess, it hurt! But she was better than this. She could do it! And already, the heady rush of pleasure was starting to dull the pain of that big cock being where it was never meant to be.

"Amelia, honey," Jimmy said from behind her, "are you okay?" He must have known. He had to have known what had just happened.

She didn't answer. She could show_him how okay she was. Her answer was the way she started rocking her hips, stirring her already-sore insides with his massive cock. Almost half his cock - the thickest half - was still entirely outside of her, but there wasn't anything she could really do about that. She wasn't above the limits of biology, after all. But she _could move like the seasoned, sexy kitty she was, lithely rolling her body back and forth on top of him. Her belly bulged where the tip of his cock was, and she knew everybody in the crowd would be able to see it.

And she was getting close to orgasm, too. Damn close. But she couldn't let that happen. She couldn't let herself crumble into a trembling wreck like Priscilla had. She had to hold herself back as long as she could, keeping that orgasm at bay so that she could appear cool, confident, and in control of this impressive stallion underneath her.

It wasn't easy. Especially not when he began pressing up into her at just_the right point each time she went forward. She wasn't the only one here with experience, she quickly realized. Jimmy had been around longer than anyone else in this whole building, and he definitely knew what he was doing. Amelia forced herself not to think about why. Instead, she distracted herself by leaning down a bit and stroking the rest of his cock, everything that wouldn't fit inside. So thick and meaty! She couldn't even close her hand around his girth. And somehow that was _inside_her? Her fingers played across the veins around his base and the rim of his sheath. Even the hole in her crotchless panties was stretched tightly around his shaft. They hadn't been designed with such huge cocks in mind. Why did he have to be so damned _sexy?

What she was really unprepared for, though, was when he took charge. There was no other word for it, and with how much effort she was putting simply into holding her orgasm back, there was little she could do to stop it. Jimmy reached up and gabbed her hips, suddenly taking full control of her motion. And he used that control to absolutely fuck her from below.

He couldn't move much, of course. There was nowhere left inside of her for that cock to go. But the motions inside her still were enough to break through all her barriers. Her tongue hung out. She screamed out moans for the whole crowd to hear - she just couldn't help herself anymore.

Even worse, he was starting to flare. His tip swelled inside her womb, locking him in place and stretching her obscenely from the inside out. It looked so wrong_to see the huge, trumpet-shaped outline of his cock right through her belly fur. And the sensations! It was beyond pain, beyond pleasure. As if his cock was a lightning rod hooked straight into her brain. As if he was a puppeteer wearing her like a glove and controlling her every movement. Her pussy _and her womb squeezed down against his shaft ... in complete futility. There was no give in his ardently hard cock, not even the slightest modicum of extra space to be gained. Everything inside her belonged to him now.

And that's when her orgasm truly hit. "Daddy!" she cried out uncontrollably, at the top of her lungs. Her back arched and she clenched even harder on the inside, every muscle in her whole body going rigid and tense.

Right into that tension, right into that sizzling ball of ecstasy, her father came inside her. Directly inside her womb. Cum _blasted_into her, quickly ballooning her belly outward, stretching her skin to the point where her belly fur looked sparse and thin. With one hand still gripping the base of his cock, she could feel every powerful throb as it traveled upward, getting a slight bit of advance warning before each one lit her pussy up on its way through before splashing into her, pooling inside her. She could feel the sudden jets of it tickling against her very innermost secret of places. Her hand was getting slick and warm from the excess leaking out between her tightly stretched pussy lips and his still-pumping cock.

Amelia was nearly as devastated as Priscilla had been by the time it was over. But only nearly. She still managed to stand up, her pussy gushing_excess cum onto her dad's crotch as his softening cock fell out of her. Had she really screamed 'Daddy' in front of everybody? But ... that was a normal thing that girls sometimes said during sex, right? It didn't _mean anything. And surely, none of them would guess that he was really her dad, would they? He sure didn't look old enough to be.

Even as the cum slowly drained out, her belly was still huge. Rubbing it with one hand, she raised the other hand in triumph. The crowd actually cheered! She'd be sore later, but for now ... for now, she was the Prom Princess, and nobody could deny it.

Chapter 5

Jimmy relaxed and enjoyed the view of the city below from the seat of the fun little convertible. The top was up, though. After all, they weren't the only car here in this lookout spot. Most of the others had come here from the prom, too.

What was really enjoyable, though was the feeling of his daughter's mouth on his cock. She was actually really_good at this. He'd never expected her to be so experienced and skilled. The way she slid her rough tongue up the side of his shaft made him tingle, and the way she plunged her mouth down onto his tip made him moan. Every part of him down there was soaking in her drool as she completely and totally _gave herself to him. His pants were going to be stained, and he'd have to get the car cleaned before giving it back, but none of it mattered. Damn she felt good!

He ran his fingers through her hair, being careful not to disturb the glittering Prom Princess tiara on top of her head. "You know," he said, "you don't have to do that. The prom is over. You don't have to pretend to be my girlfriend anymore..."

Amelia took her mouth off of his cock just long enough to say, "Shush, Jimmy. It's tradition. And besides ... you earned it."

She went straight back down onto his cock, taking it deep_this time. How was she squeezing such a big thing into her little throat? He could see her neck bulging around his tip. With his hand still in her hair, he had to remind himself not to push her down. However good that might feel, it just wouldn't do to treat his own daughter that way. And besides, she _had to be pretty close to her limits already, right? Instead he slid his hand down her back, along her dress, underneath her. Though fairly stretchable, the dress still barely fit over her still-swollen belly. He had to admit he hadn't had a night this good in ages.

Amelia came up for air, but didn't pause what she was doing. Even as she sucked in deep breaths, she bent down lower and licked at the cleft between his balls.

He moaned again. Yeah ... he _definitely_wanted more of this in the future. "Maybe I was good enough to earn another visit from 'Jimmy' in a week or two?" It should be safe enough to take the serum again by then.

"Don't push your luck, Dad." She looked up at him, her slitted eyes sparkling in the low light and his shaft still pressed against her face. "Though I guess I will need a date for graduation night..."
