Comission for Lucashoal 
The thin, lanky male fox walked out of the impressive looking kitchen of the diner where he worked as main cook. he was dressed in standard chef garb: a long, cylindrical hat and white apron, and did his best to look proud and self-assured as he walked out to the very rich, very important customer that he had been brought in that night specifically to cook for. He was, after all, the best chef the restaurant had. Who else could they call with such a prestigious guest on the line? Luca, the red fox in the hat and apron didn't know, nor did he care, but couldn't help but blush and lose his composure at the sight of the great, blue dragoness, almost eight feet tall, which eyed him carefully; she was the only person in the dining hall, having reserved the entire restaurant for herself.
"Well, I had no idea you were so cute," the VIP dragoness said, leaning over her table and giving him eyes warm with desire, "I would have asked for you sooner."
Luca knew a come-on when he saw one, considering he moonlighted as an extreme sexual deviant, and made sure to expose his curvy, feminine rear to her as he leant over to place the covered platter onto the table. "Your entre, madam," he said, a bit confused about whether he should let her flirt with him or just continue cooking for her clearly ravenous appetite. 
Luca gasped and tensed slightly as his exposed buttocks was shamelessly groped by the clearly wanting dragoness, but didn't pull away, only blushing as she swatted, grabbed and played with his vaguely female rear end. Luca was an exhibitionary lover of sex, and paid very little attention to the what, when, where, why or even how, and, for the fox, who even at that moment was dressed in a pair of bright pink rhumba panties under his uniform, the more kinky and humiliating the better. 
"Well, well, I see someone's a well-trained employee. Customer's always right, aren't they?" the blue dragoness said, reaching a few fingers into the back of his pants and pulling the eager fox towards her, Luca's only reluctance being that he was currently in full view of his boss. "Oh, don't worry about them," she said, glancing at the very well dressed ferret in the suit who managed the restaurant, "I own the place. I could very easily put you through... Mmm, advanced training right here in the dining room if I chose, couldn't I, foxy?"
"Y-yes, Ma'am," Luca said, trying to stifle a moan as his highly cultivated rear end was played with like the dominant's toy he had intended it as.
"And I could do anything I wanted with you, couldn't I?" The fox couldn't hold back any longer, and gave a high, warm, purring feminine moan as the dragoness's paw slipped down the back of his pants and began teasing him properly, but the hand was withdrawn right away, and wrapped around his wrist, drawing the fox along as she left through the front doors with him, meal abandoned.
Luca followed along perfectly willingly, not even trying to hide his blush as he was taken outside, little cock throbbing in his panties, and led as much by force of personality as by strength of arm over to the dragoness's extremely expensive automobile, which was parked in the VIP spot. 
"Stay still," the dragoness said, firm but kinky, and opened the trunk, returning a moment later with two or three rolls of duct-tape, "Let's make this a little more interesting, shall we, foxy?" Luca gasped and nodded at the realization, gladly turning around and offering his arms for bondage. With a strong, dominant, practiced hand that made the little sissy fox squirm, the restaurant’s owner practically cocooned him in the sticky, synthetic tape, with a few tangents wrapping around his muzzle, and a black fabric blindfold pulled over his head. All this was done shamelessly in the evening sunlight, in plain view of anyone who happened to walk by. A clear display of this woman's perceived and real power and authority. 
Blind, mute, and immobile, the much larger female reptile hefted Luca over a shoulder, then, unceremoniously, deposited him into the trunk for transport. She wasn't violent about it, but the luxury car wasn't a minivan, and rather conservative on the trunk space, leaving Luca neatly uncomfortable against her sweaty yoga pants, covered in the very familiar, very appealing smell of a hermaphrodite dragon. Suddenly his evening prospects doubled in appeal, and Luca's squirming and moaning were more from excitement than discomfort.
"Oh, shoot. Too bad I couldn't fill that tail of yours back at the restaurant," Luca's newly self-appointed dominant for the evening said, opening the trunk after some time and distance had passed, and carried the taped up fox haphazardly for a while, occasionally knocking him playfully against a wall or doorframe. Not with intent to hurt, of course, at least not physically. The dragoness wished only to make this fox realize precisely who was in charge her, not that she imagined Luca would be the fiesty sort, but precedent must be set in these sorts of relationships.
After being carried down some stairs, Luca felt himself dropped into an armchair. Still bound and cocooned in the sticky tape, he could do almost nothing to escape, and wouldn't have even if he could, enjoying this as much as he was.
There was a shrill tearing noise as Luca's dominant put a sharp, draconic claw between the tape and his fur and tore it, and his uniform, right down the middle. The fox's muscles cramped after almost an hour confined as such, but he was too occupied thinking about what sort of wonderful, kinky torment would be laid upon him by this ravenous draconic herm, with a whole night between them and all the money in the world to buy equipment. 
She tore off his duct tape muzzle shortly after, which didn't pull at his fur as he had expected, only peeling comfortably off to be disposed of in a nearby rubbish container. "Cozy stuff, isn't it?" the dragoness said, removing Luca's blindfold and revealing to him the elegant, beautiful master suite that must surely have belonged to her. He had been sat in an armchair in a corner, but that was only one of four or five luxury furniture sets that had been set up in the bedroom. The room was five or six times as large as a bedroom strictly needed to be, and contained no less than three dressers, two wardrobes, a massive, heart shaped bed with a mirror above it, two large footlockers, assorted miscellaneous furniture and ample empty floor space. It was the play room of Luca's dreams. "Now, how about we get down to business, my foxy little kit?" The dragoness said, having half undone her suit's buttons to reveal her ample bosom, a look that practically personified female dominance. "My name is Selena, but, from this point on, you will refer to me as mistress. Understand?"
"Yes, mistress," Luca replied without an ounce of hesitation, dropping out of the chair and down onto all fours so he could properly worship his newly acquired dominant, all three of the kitsune's tails dancing behind him.
"There's a good kit. Breaking in a new acquisition is always fun, but there's a special joy in the pets that live and breathe submission. Isn't that right, cutie?" Selena said, circling the prostrated fox, and groped his panty covered bottom again, "especially when they have such fine taste in lingerie."
"Of course, mistress. Thank you, mistress," Luca said, barely audible past his purring as he was inspected, and yelped in surprise as the dragoness's hand slapped him on the pantied behind.
"There's a good girl. I love it when my little pets bow and scrape," the dragoness said, putting a foot up on the back of Luca's head and forcing his nose into the carpet, not that he minded, and even muttered his thanks for the compliment. "Oh you are in heaven, aren't you? You relish the thought of being treated like the horny little girl you are. I'm a dragon, you know. We have very keen senses of perception. I can even tell what your fantasies are, can't I?" 
"Y-yes mistress?" Luca replied, a bit less sure than before. He'd had a dominant try to play mind games with him before, but generally he could see through them, even if he pretended he couldn't. After all, it didn't take much of an eye for kink to tell that the boy that wore panties to work had a thing for forced feminization and cross-dressing, did it? He might have contemplated the situation more, but felt the foot remove itself from the back of his neck, and Selena's equal parts strict and affectionate voice give him a new order.
"Loose the panties, I want to see what pretending to be a boy has done to my little girl," she said, ordering him back up to his feet with a wave of the hand. Luca didn't hesitate this time, gently pulling down his panties and using his swaying tails to tease her a bit, but the dragoness seemed more occupied with the cylindrical, metal tin that she had in one hand than whatever he was doing. "Do you want to be a girl, Luca?" the dragoness said, turning her attention back to him, "what am I saying? Of course you do. You want to give me what I want, and I want my little girl to have the correct parts."
"Oh... oh yes, of course..." Luca said, shuddering all over with arousal and impatience to proceed, his tiny sissy cock fully erect to its one inch length, then belatedly added, "Err... mistress." Luca had been a transvestite for as long as he could remember, going all the way back to liberating lingerie from the underwear drawers of female relatives and friends, and gradually acquiring girl clothes to wear whenever he had the time, or someone to put him in them. Becoming a true female was always a fetish of his, but one that was unfortunately limited by his means. The surgeries were expensive, they took a long time, they were irreversible, and, no matter what, he would never be an authentic female. Just the thought that this dragoness, with her vast resources, might be able to deliver that authentic experience that he so desired was intoxicating, and he could barely whimper he was so horny.
"Then let's make a girl out of you," the dragoness said with a sly wink, and opened the canister that she had been holding. Luca didn't know what he had been expecting, but it wasn't what he got. The tin was full of a semi-solid mass of contrasting blue and white substance, almost like heavy body paint, and the three tailed kitsune simply didn't know what to make of it.
"W-what's that... mistress?" Luca said, blushing at the gleam of it, reminding him of rubber or latex, both of which were intense fetishes of his, and deeply wishing she would stop teasing him and get on with it already.
"Something very unique, and very expensive. Think of it like a... body paint," she gave a wink, watching the naked fox blush and hold his paws behind his back. The dragoness didn't wait for permission to reach three fingers into the canister, scooping out a small puddle of the paint, then wiped it across Luca's belly.
"O-oh!" Luca exclaimed, feeling the paint instantly stick to his fur like glue, adhering to him and bullying his fur flat as it bound to his skin. It didn't stay still, either. Even as he watched, the paint started to seep down along his chest and belly, seeming to almost spread out as it formed a glistening, uniform, paper thin coating over the better part of his chest. Luca's paw instantly went to the still wet rubbery fluid, which seemed to have solidified into an inorganic sheet that stuck to him. He couldn't even get his claws under it at the edges, so tight was it to his skin. 
"Hold still," Selena said, scooping more of the paint out of the canister and applying it to the fox's arm. Instead of just dripping down, this time he was sure he watched it spread up his shoulder and along his hand. Not painful, exactly, or even uncomfortable. There was a bit of tingling as the paint adhered, and a seething tightness in some areas, but, being the enthusiast of shiny, kinky things that he was, Luca didn't mind in the least. The dragoness got more generous, seeing that Luca was eager for more, and began gently but firmly coating him with it, allowing the liquid synthetic to bind seamlessly as it reached a junction while the fox moaned and groaned in ecstasy. She worked from the shoulders down, permanently encasing his claws in their sheaths as his fingers were coated over, Luca's already round, feminine posterior being molded into a broad, inflated ass worthy of a Brazilian dancer. Within ten minutes she had coated him from the neck down, tails and all, and Luca was happy just to stroke his paws along his squeaky, shiny body to hear the resounding noises it made. 
When Selena had coated Luca's tiny cock and genital region, she had intentionally applied more of the rubbery paint than seemed necessary, with the extra serving as a means to permanently bloat over his genitals, sealing them chaste and away under a small mound of rubber between his legs. Both parties approved of this development, and Selena took the liberty of playing with the fox's new chastity mound, just to make sure he couldn't play with himself until the paint, which was much more than just a liquid synthetic play suit, had finished with him. 
With that little detail taken care of, Selena turned her attention to the only part of Luca's body which still remained uncovered, his head, and took an extra-large handful of the living rubber in her paw as she reached for the shiny fox's face. "Do you know what you are, Luca?" the dragoness said, looking at the kitsune for a reaction.
"I- mistress?" Luca said, feeling the much larger and more dominant female coat his neck with the rubber paint, which seemed to do something to his vocal cords, because his words came out much more high pitched and girly than even he could manage under normal circumstances, considering he had been practicing for years.
"You are my pretty little love doll, Luca," Selena said, grinning down at the fox, who, even as they spoke, had a pair of slowly inflating breasts on his rubber clad chest, and the beginnings of his new female vent splitting down where his boy bits had been before, the mound that had covered them seeping away into the rest of the suit, "Forever and ever. You exist only to serve me, your mistress, or whomever I allow to rent you, my prized possession. Isn't this true?"
"Y-yes, mistress!" Luca said in his, or, rather, her high pitched voice with real, honest enthusiasm as the latex crept up over her ears, muzzle, nose and face, "I- I exist only to serve you, mistress."
"Such an obedient little toy," Selena said, reaching down between Luca's legs and pushing two fingers into the fully formed rubbery vagina that hadn't existed five minutes before. Luca yelped in surprise and amazement as the dragoness's fingers pushed deep inside of her, wiggling around and forcing impulsive, lusty moans past her lips.
"Oh... Oh! D-deeper, please deeper, mistress...!" Luca begged, feeling disappointed as the dragoness withdrew her fingers and wiped them off on the furniture.
"It is not the toy's place to question her mistress's judgment, is it?" Selena said, clearly going easy on the newly minted female considering she had never been played with as a true girl before.
"Oh... Yes, mistress," the blue and white rubbery fox said, cheeks going pink even through the layer of paint, which had, by that point, seriously altered her genetics to fit the whims of her mistress. 
"That's a good girl," Selena said with a smile, and scratched behind Luca's ears, "How do you feel, girly? Would you like to show mistress just how much of a stretchy pup you are?"
"I feel great!" Luca said, tails all wagging about behind her as her rubbery fingers drifted towards her nethers, just barely keeping the desire to masturbate in check. When the offer for sex was made, the fox's eyes went wide with need, "Oh, yes please mistress! Make me a good stretchy girl!"
"The stretchiest I've ever made," the dragoness said with a wink, and yanked Luca up off the ground by the nape of her neck. Luca yelped at the sudden lift, but more out of surprise than pain. In fact there was no pain at all, just an odd feeling of... distention, like her body was doing things it had no business doing. "That paint is deep inside of you, now," the dragoness explained, "it's more than just a coating. Your body is taking on the properties of the synthetic. I wasn't lying when I said you'd be the stretchiest girl in town, Luca."
The newly turned girl absolutely beamed at this news, imagining just how many new things she could try, now that she had three fuckable holes and a mistress who had a desire to fill all of them, preferably at once, all of which could be filled with bigger, badder toys and objects than Luca 1.0 could possibly have imagined. This was her dream come true, there was no other way to explain it.
Selena dropped the rubberized fox down onto the heart shaped bed, then kicked open one of the footlockers while rubbing her hands together, “Now, now. What to start you off with?” the dragoness said, and eventually pulled a reasonably upper medium dildo out of the chest, showing it to Luca. The fox fought the urge to question her, but her face showed what she thought. “Oh, my little sex doll is feeling ambitious, isn’t she?” Selena demanded, “I like that in a toy. Wait a moment, I have just the thing.” 
Even Luca was impressed by the toy that the dragoness brought out next, something that even the ever stretchy fox would have had to work himself up to over the course of several days. Back when she had still been a he, that was. The dildo was some sort of experimental cross between a dragon and a wolf, with the former’s plates and ridges, and the later’s large, prominent knot. In Luca’s experienced estimation, that toy looked like a hell of a fun time, and she gladly assumed proper toy-receiving position on the bed, on her hands and knees, tail up. “Don’t be gentle!” Luca begged, shivering with need and female desire. The dragoness didn’t use lube on the massive dildo, giving Luca a bit of pause for thought, but it didn’t last long. He had taken big toys dry before, and it was never pleasant, but he’d get by. If anything it made him more aroused to know just how unrelentingly powerful this draconic herm could be when she felt like it.
“Here comes the alpha dragon, pup, ready or not,” Luca’s new owner said, pressing the almost pointed tip of the toy up against the kitsune’s puckered, rubbery tail hole, which quivered with anticipation of the massive toy that was about to fill it. 
“O- Oh!” Luca exclaimed as Selena put pressure on the dildo, and her normally tight hole spread wide to accommodate it without even the slightest pain, but a great deal of extremely arousing discomfort. Her rubberized rectum didn’t put up any resistance to the invading toy, and Luca moaned out her horny lust as the ridged and plated cock worked its way deeper and deeper into her, spasming in pleasure and nearly falling over when the nubs pressed against her newly formed G-spot. She had been stretched effortlessly to a gape that even the sluttiest of foxes would be proud of, and showed no signs of stopping. By the time the toy had been worked up to the massive, six inch wide lupine knot at the bottom, three quarters of it already inside of her, Luca was a moaning, needy, writhing wreak of a vixen, but Selena didn’t let up for a second. She renewed the pressure on the toy, spreading the fox even wider back there, not even her newly modified hips getting in the way of the truly epic girth of the toy. When, finally, after five minutes of work, Selena pushed Luca past the point of no return and let the pathetically moaning fox’s behind close on the massive toy, the kitsune crumpled onto the mattress, stuffed to capacity and with plenty more to come. 
“Now, let’s get that little pussy of yours ready for me,” Selena said, grinning sadistically as her toy wiggled helplessly on the bed, in the throes of a massive female orgasm. She reached into her box and pulled out another dildo, almost as big as the previous one except lacking a knot, this one equine in design and sporting a flared tip. “You’ll learn to take bigger horses than this, my little toy. I’ve half a mind to see you mated to the stable horses!” She said, maneuvering the squirming, writhing fox onto her back and spreading her legs to get a good look at her vent, “My, my, what a tight little girl you are. Let’s fix that, shall we?” 
Luca’s memory failed her after that, and could never fully recall having the horse dildo penetrating her. There were flashes as she experienced her first true female orgasm, thrashing back and forth on the two massive cocks, both wielded by the masterful hand of Mistress Selena, who knew exactly how to keep a girl trapped at the edge of orgasm, sometimes for several minutes, and then only afterwards allow her to go over the edge. When it was all over, Luca was still, lying on her back on the bed, whining in absolute ecstasy and panting frantically to get her breath back. 
“Don’t get too comfortable, your night is just beginning,” the dragoness said, pulling off and tossing her coat and shirt to reveal her supple, firm looking draconic breasts, then began tugging down her pants. One glance at the massive bulge in the dragoness’s black, silky panties and Luca knew that this was one extremely well endowed herm, probably bigger than either of those dildos she had just taken, and almost as big as the two of them together, insane as it might seem. She was a giant compared to the fox, but seemed perfectly ready and willing to ruin the fox vaginally, anally, and orally. She pulled down her panties and kicked them away, confidently showing her great, draconic length. It didn’t quite have all the intentional flourishes of the dildo, but Selena’s cock was a sight to behold nonetheless, a plated, ridged and molded masterpiece of nature at its finest. Luca was honored to have the opportunity to take such a cock, and promptly reassumed her slutty bottom’s up posture.
The dragoness didn’t speak again as she lined up her cock with Luca’s significantly loosened but still very usable ass and began gently working herself in and out of the fox, more for her own pleasure than out of any concern for Luca, but the benefit was mutual. The two of them moaned and groaned in unison as Selena’s cock pushed deeper and deeper inside of the kitsune, tails going all over, every which way, her stroke rate increasing on and on as she bucked her powerful hips, thrusting her powerful cock, and then, finally, with the force of cannon fire, released her load of scorching hot dragon cum into Luca’s rear, panting from the exertion. She pulled out, and the draconic semen spilled out and down the back of her legs as her mistress cleaned herself up.
“What did I say? Stretchiest girl in town,” Selena said, chuckling to herself as she put away her cock, and examined the twitching, moaning, wreak of a rubber vixen. "Now, I've got a handful of things I'm going to try out on you, girly. Those breasts of yours are partially hollow, after all, and I always put a new invention to good use." When Luca, still recovering from her first ever fucking as a female, didn't immediately jump to command, the dragoness sped things along by giving the rubberized fox a tart spanking across the tight, womanized buttocks, startling her and bringing her back to reality. "Do not make your mistress wait, Luca."
"Oh- Oh, of course not, mistress!" Luca gasped, and hopped down off the bed and down onto all fours, tails all wagging behind her, and realized just how terribly empty she felt after having such massive toys forced into her now gaping, shiny tail hole. She considered asking her mistress for another toy, but thought better of it. That wasn't hers to decide.
"There's a good girl," Selena said, and gently fastened a leather collar around Luca's neck, from which dangled an engraved tag stating her ownership and status as a pet. The fox couldn't keep the blush off her glistening, rubbery face and crawled over on all fours to her mistress, who had pulled a large pressurized air tank from a closet, not minding the damage that the metal tank did to the hardwood floor, and stretched the rubber hose over to where Luca was watching, curiously. "This might feel a little weird, at first, but you'll get used to it," the dragoness winked, and, to Luca's shock, forced a metal air nozzle through the rubber of one of her breasts and into the hollow sacks beneath. It wasn't painful or uncomfortable, even though Luca could feel the breasts as though they were a part of her, and only experienced a light tingling as the metal passed her synthetic skin. Selena turned the crank on the side of the tank, and Luca gasped for air as her breasts suddenly filled with gas, somewhat lighter than air, and simply kept expanding to ridiculous levels. Thanks to the helium or whatever it was in the tank, Luca's breasts, however massive, didn't sag, but remained firm and perky despite their great size. "Beautiful, Luca. Don't you just love them?"
"They're perfect, mistress!" Luca exclaimed with a broad grin, fondling her newly acquired breasts and squeeing with delight. They'd tear apart even the stretchiest bra that Luca owned, so either Selena would have to invest in something special for her, or, much more appealingly, just have her toy let them hang all the time, maybe led around at parties for the guests to fondle and play with.
"I'm glad you think so, my little toy," the dragoness said, reaching over to stroke Luca's hair, and pushed the feminized fox back on her haunches as she again whipped out her cock, looking very smug, "bring me those beautiful tits, Luca. Mistress wants to take them for a spin." 
Eyes going wide with delight, Luca spread her huge, firm breasts as much as possible, letting the vastly larger dragoness position herself in such a way as to properly use them. The fox had always daydreamed about having breasts, and having them toyed with in such a way, so, even though she didn't get any great pleasure from the dragoness's ridged, bulging cock forced its way back and forth through the fox's breasts, Luca was trembling in horny, needy ecstasy the whole while. She could feel her mistress's heartrate increase in preparation for her second orgasm that night, and her stroke with the massive cock took on a more jerky nature than the consistent back and forth Luca was learning to expect. Taking the initiative, the rubbery vixen leaned forward, feeling amazingly flexible now that she was a perfect latex love toy, and took the head of Selena's cock into her mouth, happily adding her expert tongue and lips to the task.
The dragoness moaned in pleasure, and gave up thrusting all together as Luca drove her over the edge once more, this time using nothing more than her mouth and tits, and backed off slightly as she dropped her load right between the fox's eyes, hot jets of cum spurting in bursts out of the dragoness's cock to splatter across Luca's face and run down the sides of her head and muzzle. 
The cum covered fox made to be a good girl, and lick as much of her face clean as possible for her mistress, but Selena didn't give her the chance. "Oh, girly, girly, girly, you are a wonder," the dragoness gasped, picking up the fox over her shoulder with little apparent effort and carried her post-haste out the door of the play room and down a teak and mahogany hallway, Luca still dripping the dragoness's hot, steaming seed. Selena carried her out the front door of the mansion, and dropped the rubberized fox shamelessly into the trunk of her car. "A gift like you is one that needs to be shared," was all she said, then winked and slammed the trunk shut, leaving Luca horny, quivering, and eager for more. This had already been the best night of her life, already, and the thought of many more like this was almost enough to make the fox explode with anticipation. 
Luca played with herself a bit for entertainment, and wiped off her face with the dragoness's yoga pants. They already smelt of her cum, so a little more certainly couldn't hurt. The trip was short, and a few stops were made, until finally Luca heard the front door to the luxury car slam shut and, in a few seconds, the trunk open up.
"Get out," Selena instructed, still dressed in about half of her usual attire, and accompanied by an unspeakably attractive brown and white speckled stallion, his surely monstrous cock bulging in his pants just at the sight of the rubber toy vixen.
"Well thank you, Ma'am, don't mind if I do," the muscular epitome of masculinity said to Selena, and then smiled at the amazed vixen, and picked the frantically needy fox up over one shoulder, carrying her down a back alley in one of the many entertainment districts of the city.
"I'll leave you two alone, just call me when you're done with her and I'll come pick her up. Don't worry about being gentle, Luca here likes it rough."
"Be sure to keep that in mind," the great stallion said with a chuckle, and carried Luca down an adjoining street to a nearby motel where he just walked into a room, either paid for in advance or invaded by a party that didn't care too much for paying at all. 
Luca positively purred in mixed anxiety and excitement, simultaneously drunk with pleasure from the idea of being made this muscular male's plaything, and a bit anxious for her own safety. Even in comparison to the massive dragoness she had taken with ease just a half hour earlier, this horse was shaping up to be beyond enormous. He dropped the blushing, squirming vixen onto the bed and started to undress, throwing his pants and tank top across the room to pile in a heap, and revealed the truely epic bulge in his tight underwear, which showed him to full advantage.
"Now don't squirm too much, I like my girls nice and easy," the stallion said, grinning, and disposed of his athletic underwear, and showing Luca something that made even the works of art that had been tested on her earlier seem small in comparison. It wasn't so much that the horse cock was bigger than Luca expected, but also that the head, which flared out at the tip, was nearly as large in comparison to his shaft as a canine's knot would be. "Now let's see how good you are, vixy. Down on your knees."
Luca obeyed with mingled enthusiasm and relief, she always loved giving a good blowjob, even to a cock that wouldn't fit in her mouth entirely. That didn't matter too much, not to a masterful sub like Luca. The fox leapt in with energetic and experienced ease, licking up and down the stallion's vast, bulging cock, and letting it slide horizontally along her muzzle so she could use her tongue to full effect. The horse was clearly surprised, and put his hands on the back of the fox's head as he moaned, "Oh... yes, that's the spot."
"M- mmhmmm!" Luca sputtered, fitting the better part of the horse's head into her mouth and gently licking around to find his pleasure buttons, as well as intentionally getting his pre all over her nose. A few minutes of foreplay longer, and Luca had the stallion shivering and pulling Luca's head deeper onto his cock, only possible because of how flexible and stretchy her new body was.
"Now for the fun part," the well-endowed equine said, and seized Luca under the arms, hefting her up to about chest level with no visible effort and turning her around. Luca figured out what he meant to do right away, and yelped with excitement as she spread her legs, exposing her virgin clit and vent, which the horse slowly lowered onto his cock.
"Oh- Ohhh!" Luca yowled as the hot, smooth flesh of the horse's head rubbed against her clit, gently spreading the lips of her newly minted vagina. As much as both of them would have liked to, just slamming such a huge cock into Luca wouldn't be safe, even rubberized as she was, but that didn't stop him from being rough. The shiny fox moaned in feminine ecstasy as the horse lowered her down again, forcing his cock past Luca's moist, needy lips, then pulled back again just before the head of his cock passed through. He started again, up and down and up and down, all the while the two of them groaned enough to merit an entire orgy. 
Once the stallion had properly stretched Luca wide enough to get inside her, all bets were off, and he used both his own muscles and Luca's weight to force the fox down onto the great shaft, the fox howling as she was filled to the brim with horse cock.
The stallion kept his self-control admirably evident throughout the encounter, even as he worked Luca up and down and up and down on his great shaft, always sure to keep that massive, equine head inside her, filling her, and gradually working his way deeper into the fox's new girly bits.
The world as Luca knew it collapsed into a room sized white bliss containing only herself and the horse as she orgasmed, spurting fluids onto the horse's cock and whining so loud that she must have woken the entire motel complex, but then her partner came, filling her with a torrent of hot, steamy horse cum and bringing her pleasure to a whole new level. By the time the horse had pulled out of the fox, who laid twitching on the floor, cum slowly leaking out of her female vent, Luca was practically immobile. This was the peak of life, nothing in the world could possibly get better than this... could it? Twenty four hours ago Luca had been an exceptional, but not uniquely talented chef working at a prestigious restaurant, and indulging in kinky things in her down time. Now that was her life, and years of wonderful opportunity stretched in front of her, backed by a sexy mistress with all the money in the world and desiring no pleasure that Luca couldn't provide. This was the life, and it had only just begun.
