"Don't sulk Trevor! It's your birthday, you should be having fun..." the colt's mother insisted, bending over to fix his mane.
               Trevor wholeheartedly agreed with his mom - it was his birthday, and he should have been having fun. And he would have been having fun if his parents had thrown him a normal twelfth birthday party, instead of arranging for some fort of fancy gala. He was promised he'd be able to have friends over tomorrow for the sort of celebration he was used to, but they insisted that tonight would be special - a birthday to remember!
               Well they were right about that. I've never even heard of a kid's birthday with only one kid. Gotta be pretty special...
               The other attendees were all grown-ups his parent's age, which to the colt meant 'old people who didn't really see themselves as old'. The sort of people who thought dressing in fancy clothes and going to a boring party where they just talked, and talked and talked all night long was fun. Even he was wearing a suit and tie. The colt had actually been kind of pleased when he looked at himself in the mirror in his new outfit, figuring his mom and dad thought he was on his way to becoming a grown-up and should dress the part. But any hope of being seen as anything other than a little kid evaporated when guests started arriving and words phrases like 'cute' and 'little man' started popping up, often accompanied by 'aww's from the female guests.
               He still didn't get this. There were some familiar faces in the crowd - a few aunts and uncles, cousins that were twice his age, and some of his parent's friends he'd seen before. But there were also people who were complete strangers to him, but they all seemed to more-or-less know each other. Everyone had a glass in their hand, Trevor included (even though his was filled with sparkling cider) but none of them seemed drunk or intent on getting drunk. So the colt continued to sulk, because he honestly didn't know what else he was supposed to do at the most boring, confusing and downright stupid birthday party in hos whole...
               "Hello everyone! Sorry I'm late but traffic was just a mess..." came a voice from the door, rich deep and with a subtle rumble in the 'R's that actually had Trevor's long ears flicking as they caught it. His attention was drown to the entryway of their house, along with every other guest, in time to spot the owner of that voice.
               The panthress was eye-catching even wrapped up in a long black coat, the thick, fur-trimmed fabric failing to hide the curves lurking underneath. And 'lurking' seemed like a good way to describe the feline guest. The lights had been dimmed for the party and with her black fur and black coat the only thing that really stood out on her were two yellow-green eyes that seemed to sparkle in the soft light.
               "Olivia! I was worried you might not make it." Trevor heard his mother coo out, making her way towards the panthress and kissing her on the cheek.
               "You know I wouldn't miss this for the world." The ebony feline replied in the same husky tone, and Trevor couldn't help but roll his eyes. I would have been thrilled to miss this, and it's my party! He thought, the name 'Olivia' seeming to rattle around in his head, trying to find something to connect to. Slim chance though. He'd been introduced to so many people tonight, it was a wonder he could still remember his own name.
               "Here, let me help you with that..." he heard his mother say and was about to turn away when Olivia opened her coat and a flash of silver held his attention. The colt was sure his mouth had actually fallen open at some point, and he could hear the conversation falter as the other guests caught sight of the panthress.
               The material of her dress was something shimmery and almost metallic, and even though the flashy fabric had initially caught his eye, it was the jet-black fur it exposed that held his gaze. Particularly considering how much fur it showed! Trevor wasn't sure if there was any kind of dress that could really hide the lush feline curves the panthress boasted, but the dress she was wearing now wasn't even trying.
What should have been a neckline couldn't rightfully be called that since it plunged down nearly to Olivia's belly button. The two heavy yet perfectly firm breasts were only barely covered by the silvery fabric that tapered into straps that were tied behind the feline's neck and seemed to be the only thing holding the garment up. The other women at the party all wore fancy dresses, but this looked like something that wasn't meant for just a fancy party. It looked like something you'd see on the red carpet...
"Trevor, I'd like you to meet Olivia..." his mother said, and just then the colt's brain came up with the black cat's last name.
Lenox! Olivia Lenox, the actress! The colt thought to himself, stunned to realize he, for some unfathomable reason, had an actual celebrity at his twelfth birthday party. It took him a while to connect the dots since he'd never really seen her movies because they honestly seemed like boring dramas and romances. But he'd seen her in advertisements and on posters, although never so much of her as he was seeing now.
"My my, if it isn't little Trevor..." the panthress husked, and something about the rich, deep tone of her voice made the colt's spine tingle and his tail twitch. "Or at least it was. Ooh, you've grown so much since the last time I've seen you! Why in a few more years you'll be a young stallion..." she said, running her hands down the sleeves of his jacket and seeming to really mean what she was saying. The colt had heard plenty of "how you've grown"s this evening, but none of them sounded genuine. Everyone else seemed to think it was cute that his parents had dressed a kid in grown-up's clothes. But when Olivia had said the same thing, Trevor had felt like he'd grown another foot then and there. 
He'd felt his heart flutter a little when the panthress flashed him a toothy grin, and felt like it had almost stopped beating when the sultry feline bent gently to kiss his forehead, and the flimsy dress threatened to reveal something he still wasn't sure he was ready to see. Although as the panthress straightened, he realized that ready or not, some part of him had really wanted to see just a little bit more...
"Come on, I've been waiting to have a little chat with you..." she said, taking Trevor by the hand and gently guiding him to the sofa.
"M-me?" the colt asked, irritated that his voice had squeaked like a little kid's after Olivia had complimented him on being so grown up.
"Of course. You're the birthday boy, aren't you? You don't mind I'm monopolizing him, do you?" she asked the room as she settled down, with everyone replying with either 'no' or 'of course not'. Trevor found it a little strange, but he didn't mind. The most interesting person at this whole party wanted to talk to him?
By the time he sat down on the couch his legs were wobbly, and his breath caught in his lungs when Olivia settled down right next to him, so much that one bare thigh was pressed against his legs. She didn't bother with crossing her legs, and with the slits on her dress going as far as her waist the silvery fabric of her gown had slipped between those shapely thighs. Trevor had thought the panthress might be wearing black panties at first, but now he could see there was no sign of a waistband digging into that luxurious black fur. It almost made his heart skip a beat knowing that if the silvery cloth were to slip to one side he would get a close-up view of the buxom felines bare...
"So Trevor, how are you liking your party?" she asked, her voice seeming like rich, thick syrup dripping into his ears.
"It's fi... I mean it's great..." the colt said, torn between an urge to squirm away and a desperate desire to stay as close to the panthress as he could.
"Honest?" she asked, the smile gracing her muzzle telling him that she'd read him like a book.
"Well, it had been pretty boring up till now..."
"Mhh, I'd hoped to be here sooner. You don't remember me, do you?" she said, and the colt just shook his head in embarrassment. "Don't worry, I didn't really expect you to. You were still quite little when I was here the last time, but I could tell you would grow into a real heartbreaker. That's why I picked you..."
"P-picked?" the colt asked, trying to keep his voice steady.
"Mm-hmm. Bet there are a lot of strange faces here, from your point of view..." she mused, and Trevor just nodded. He didn't want the subject changed, but he found himself hanging on the feline's every word, no matter what she chose to say. "That can be kind of off-putting, can't it? Being in a room where everyone seems to know each other but you? Well, the reason this little group is so tight-knit is that we share an opinion, so to speak. Namely one concerning sex..." she finished, letting the word slip from between her lips casually and fighting the urge to grin at the way it nevertheless flustered the colt next to her.
"S-sex?" Trevor whispered, aware that this was the first time he'd uttered the word to an adult.
"You know what that is, don't you?" the panthress asked, her fingers slipping around a lock of the colt's mane as the young stallion blushed through his fur.
"Y-yes, I mean... we had special classes at school..."
"And what did they tell you in those classes? When are you supposed to start?"
"W-well they said we were only starting puberty, and that our bodies were changing, and that we are still too young and should wait before... before we..." the colt stammered, trying to take deep breaths, to calm himself but only managing to get himself worked up as each lungful carried the sweet fragrance of what he assumed was the panthress' perfume.
"And do you want to wait?" Olivia asked. She'd leaned down a little, bringing her muzzle closer to one perked equine ear and pitching her rich, deep voice in a tone that had the colt's entire body going stiff as his eyes went wide open. "You know that opinion I mentioned everyone here shared?" she asked in the same intimate tone, but one she knew curious ears all around them would be able to pick up. The panthress laid one hand gently on the colt's knee, her eyes sliding a little further at the evidence of how her little act was affecting him. "It's that growing boys and girls shouldn't have to. Not unless they really want to. Do you want to?" she asked, her words almost a purr as her hand slid mischievously up Trevor's thigh.
"I... no! I mean, to waiting..." the colt squeaked out, his eyes following Olivia's hand as it came close to reaching something he'd hoped she hadn't noticed.
"I guessed as much..." the panthress husked into the boy's ear at the same moment her fingers slid over the tip of an equine shaft that had grown uncomfortably erect and trapped in one of the colt's trouser-legs. "Tell me Trevor, do you have a little girlfriend?" she asked, brushing her fingertips under the firm length straining against the fabric.
"Hah! N-no..."
"Good..." the ebony feline purred, laying a palm against the colt's shaft and savoring the way her touch made him shudder. "I would have respected that. But seeing as how you are unattached..." she said, rising smoothly to stand in front of the confused boy.
She smiled at the awestruck expression on a face that was innocent despite the erection now clearly outlined against his pants, waiting for a few seconds before reaching behind her neck. The skimpy gown she was wearing was held up with one clasp and some wishful thinking, and once that clasp was undone the whole thing slid off her mouthwatering curves to land in a silvery pool around her feet.
Trevor was dimly aware that the conversation had fallen silent for a moment, but resumed soon in murmurs, without any shock or outrage at the voluptuous panthress now posing in nothing but her fur and a smile in front of him. The colt was aware that his nostrils were flaring, his chest rising and falling as he did his best not to hyperventilate. Not only was this his first time seeing a naked woman (and one with the sort of body that could make a boy faint), but this was the first time that a woman was looking at him like that.
His eyes were locked on her form, the way the soft light shone against the sleek black fur, highlighting the generous but deliciously firm-looking curves. Without the straps of her dress in the way he could see not only those mouth-watering ebony globes gracing the panthress' chest, but the twin circular patches of bare, mocha-brown skin, each with a stiffening nipple in its center. The sway and swish of the thick feline tail brought his attention lower, past the slender waist and to the generous, cocked hips, the colt's breath catching in his throat as he spied another patch unadorned by ink-black fur, nestled just between Olivia's shapely thighs.
"Aren't you going to sing 'happy birthday' to him?" asked a male voice from behind the couch, followed by a chuckle from several guests, including the nude panthress.
"Well I would, but my throat is just so dry..." the onyx feline purred out, taking a few languid steps and - to Trevor's shock- gracefully sinking to her knees in front of him. "Think you could help me out, Trevor?" she purred, and the colt just gave a small nod, too dumbstruck to form words as the graceful feline spread his knees and began to unbuckle his pants.
"Oh my Trevor, you really have grown..." the panthress purred as she fished the colt's length out of his pants, slitted eyes taking on a hungry glint as she eyed the fleshy pink rod.
"A chip of the old block..." came a voice from behind, one that even in his dazed state the colt recognized as his father's. He was aware the even though people were still conversing, everyone had gathered around the sofa where he sat and Olivia length. He still wasn't sure what was about to happen, but he got the feeling that they all intended to watch...
"Mmmhh. You know Trevor, I've never faked it with a boy..." she said, pressing her lips to the side of his shaft and giving the throbbing length a brief kiss. "Pups, cubs, kits, colts... I've enjoyed my time with them all no matter their size. But you..." she said, peppering his length with kisses between every word or two. "are going... to be... a snug... fit!" she said, punctuating the statement with a kiss on the blunt tip of Trevor's cock, one that had the colt's hoof-nailed fingers digging into the couch he was sitting on.
"Be sure to make a wish before you blow it out!" called a female voice of to the colt's right, but Trevor's eyes were glued to the panthress lovingly holding his stallionhood in her hands.
"And hope it comes true?" the feline asked, bringing her lips down for what Trevor had assumed was another kiss.
True enough, her lips touched the blunt tip of his cock, but then spread open wide, sliding along the edge of his glans as the panthress opened her muzzle and slid it down the chocked colt's bare length. Trevor could hear his heart pounding in his ears as he felt the slightly raspy feline tongue cradle the tip of his shaft, his breathings topping for a moment when Olivia opened her bright eyes and looked up at him. Mischief danced in those slitted orbs as the panthress held both his gaze and his stallionhood, moaning into the pink rod as she slid her muzzle lower down.
The colt could feel his shaft slide further into the warm, wet muzzle, the underside slipping along the tongue cradling it gently. He could feel his tip hit something and he was sure that it was as far as the panthress could take him, which was impressive since having taken six inches she had just a little over half his shaft in her muzzle.
But the panthress held his gaze as she adjusted her posture a little, and the colt's eyes almost crossed as he felt his shaft slip into something tight, realizing only after a few more inches of it disappeared that the buxom feline was taking him into her throat. There were only a couple of inches of pink stallion-flesh left, and once her lips were kissing his sheath the colt felt rather than heard her let out a moan that ended in a purr.
He could hear murmuring all around him, and managed to catch a female voice saying "I told you she would!", sparing the gathered adults little attention as the feline kneeling in front of him reached out with one hand and gently cradled the sack hanging under the stiff length she'd swallowed.
Olivia gave him what Trevor would learn years later were called bedroom eyes - a sultry look that made his heart skip a beat and his cock twitch in the tight confines of the panthress throat. With one hand still playing with his swollen orbs, she began to slide her muzzle off his length, revealing only about four inches or so of glistening pink flesh before once again sheathing it down her gullet. All the while she purred and moaned, and the vibrations seemed to travel up the Colt's spine and into his frazzled mind.
"Don't hold back sweetie. This is just to get your first load out of the way..."
The voice made him look up, and the colt was stunned to see his mother's face. The mare was looking at him with a little smile on her face, acting perfectly normally as she watched her friend's head bob up and down her son's naked length. The colt still couldn't believe that this was happening, or what exactly his mother was talking about. He'd learned in class what an orgasm like, and a few of his friends had mentioned masturbation and how good it felt. And even though touching his shaft felt nice, Trevor always just wound up with a stiffy that took forever to go down.
But having Olivia slurp and moan around his length felt better than nice. It felt more intense and more amazing than anything in his life ever had, and each time those lips slid down over his medial ring, or her deft hands cupped and stroked his pouch, the colt felt a little bit closer to something he couldn't quite describe. The panthress' other hand was out of sight, and after a while Trevor realized were it must be. 
With his nostrils flared and his breathing rapid, he could smell the feline fragrance he'd caught when she'd sat next to him, but now realized only part of it had been her perfume. That smell had been her, and now that he was playing with herself it was only getting stronger. He remembered his glimpse of the strip of bare skin between the panthress' thighs, and the cleft where he suspected her fingers were even now buried, pumping away in time to the bobbing of her head.
He could feel himself tensing down there, and for a moment felt his sack pull up and out of reach of the feline's dancing digits. Olivia hadn't missed this, and the colt groaned as she suddenly pulled his cock from her throat, sliding her mouth off until his flare left her lips with a pop. The colt's eyes went wide at his first sight of his tip mushrooming up with every beat of his heart.
"Ooh, he's close, just look at his face!" came a feminine coo from somewhere nearby, but Trevor couldn't place the voice nor could he tear his eyes away from the panthress still kneeling in front of him. Olivia had one hand wrapped around his spit-clicked length, pumping and squeezing as her tongue danced around the rim of his flare, giving him a little wink as she kept the tip aimed at her open muzzle.
Trevor hard himself gasp as something in him seemed to give way, his vision blurring for a second as his shaft began to twitch in Olivia's firm but loving grip. He saw his tip flare out even more as the panthress cradled it on her tongue, her muzzle wide open and in time to catch the first white rope shooting from the tip. He could hear the gathered adults going 'ooh' and 'aah' at the sight, but all of his attention remained on the gorgeous black cat holding his gaze and gently stroking his erupting length, as if she was making sure to milk out every drop of warm colt-cum shooting into her mouth.
"Atta boy Trevor, let the lady have her fill!" someone called out and Olivia gave a deep murr of satisfaction as she swallowed the young stallion's load. His cock had finally stopped erupting, but as the panthress gently massaged the still hard length he could see the tip dribbling warm, gooey spunk that soon began to run down the pink length.
"Ooh, someone's been pent up. Hmm, shame to leave such a beautiful cock a mess after I've had my fun." She husked, licking an errant speck of Trevor's cum from her lips before straightening up a little and pushing her chest out.
The colt watched wide eyed as the ebony feline brought her magnificent bust closer, pushing her breasts up until his still firm shaft was resting in her cleavage. To Trevor, his stallionhood had looked huge while in Olivia's grip, but as the panthress let the length slip between her mounds and pressed them together it looked a lot smaller, almost swallowed up by the lush feline globes.
"Don't worry, I'll be gentle..." she said, and the colt realized what she meant when she began to slide her rack up and down the pink rod.
He was caught off guard by hos sensitive his cock felt after his first ever orgasm, but true to her word Olivia was being gentle, slowly lifting and lowering her pillowy mounds as the feather-soft fur between them wiped the equine shaft clean. She began to purr softly as she did, and with his cock trapped against her chest the colt could feel the vibrations against his shaft. She kept purring as she slid her bosom up and down until the fur between her lush globes was soaked and Trevor could feel his cock getting hard again.
"Mmh, looks like you caught your second wind. How about it stud, ready for more?" she husked, and when the still stunned colt just gave a nod she kissed the tip of his now spotless shaft before releasing it from between her heavy breasts. His eyes remained glued to her body as she rose, his cock twitching when the panthress noticeably wet crotch came into view, hitting the colt with the full force of her captivating sent.
"Cynthia, would you be a dear and clear this table for us?" Olivia asked his mother and Trevor unglued his eyes from the feline femininity long enough to see everyone pitching in, clearing the bottles and glasses from the table and leaving the hardwood surface bare. Trevor still wasn't sure what was about to happen, but he rose trancelike when Olivia took him by the hand. "Yes, this should be the right height..." the feline mused as she led him to the table before proceeding to undress the colt who could only stare at her.
"Well, looks like you're unwrapping your gift..." came a female voice from behind Trevor.
"Hmm, he does seem gifted, doesn't he..." the panthress replied, deftly undoing the buttons of the colt's shirt before sliding it off him. His pants went next and to his surprise Trevor didn't feel at all embarrassed about being naked in a room full of grown-ups. All of his attention was focused on that feline visage, and the hungry look on Olivia's face as she examined him.
"Mhh, somewhere between an Adonis and a cherub..." she mused, flicking an errant lock of Trevor's mane behind one perked ear. "Perfect..."
The purred-out compliment was still lingering in Trevor's perked ears when the onyx feline hopped on to the edge of the table, resting that perfectly-rounded rear on the hard wood as she spread her legs, smiling as the colt's eyes went just as wide. The young stallion was still reeling from seeing a strange woman naked, not to mention that Olivia was the most beautiful woman he'd ever seen period. But naked didn't even begin to describe the sight in front of him. The panthress was on display for him, leaning back a little with her hands braced on the tabletop behind her, the magnificent feline chest thrust and rising and falling gently with Olivia's every breath.
And as captivating as it was just to stare at the two pillowy mounds, the colt's eyes nevertheless fell down, past the trim belly and stopping only once they'd reached the panthress' crotch. The diagram they'd shown in sex ed had just been a cause for giggling and tittering, and not nearly enough to prepare the colt for the sight of the feline femininity bared before him, the lips parted gently after Olivia's fingering and wet enough to glisten. As clueless as he was, the hushed schoolyard rumors had suggested that females got wet for the same reason boys got stiffies, and with that realization the young stallion's budding masculine pride swelled at the thought that he was able to turn on a woman like this.
The panthress smiled, a warm but still predatory expression as she extended her hands towards him, beckoning him closer. His hooves seemed to be obeying her rather than his own brain, and Trevor soon found himself close enough for the feline's hands to touch his shoulders. Another step closer and he could feel them on the back of his neck, his movement trancelike as he divided his attention between Olivia's face and her naked body.
The pressure on his long neck was gentle, merely pulling him where he already wanted to go. He knew the adults were talking, still in those casual tones, but the young stallion could no longer understand them. Words went into one long ear and out the other as the feline bust began to fill his vision, his hands rising like a cobra before a snake-charmer and trembling even before they touched the bounty of feline flesh dominating his attention.
"Go ahead Trevor, it's your birthday after all..." the panthress purred, her deep voice as rich and sweet as honey as she said exactly what the colt hoped to hear.
Trevor's muzzle fell open with a gasp as he finally palmed the two soft globes, or at least tried to. He was amazed at how small his hands looked resting against the two mouth-watering breasts, the fluffy globes of feminine flesh almost spilling out of his gentle grip as he tried to heft them. Olivia responded to his amateurish touches with another purr, and Trevor could feel the vibration of the satisfied rumble with both of his hands resting on the sultry feline's bountiful chest.
Hel felt arms wrap themselves gently around his neck, pulling him closer and closer until he could see nothing but the inky-black mounds and the two little hands struggling to heft them, and smell nothing but the sweet musk of the voluptuous panthress. He only realized she'd been slowly pulling him closer and closer when his lips all but brushed against one stiff nipple, and after a quick glance upward he found his mouth latching on to the feline breast, the soft globe serving to muffle a moan he wasn't sure he'd have been able to live down. The adults around the room began to talk again, no doubt about him, but when Olivia began to whisper in his ear every bit of attention left to his frazzled mind was hers alone.
"You know what I'm offering you, don't you sweetling?" she said, every hushed word sending a fresh shiver down the colt's spine. Since it would have taken a crow-bar to pry his mouth from the panthress breast, he merely nodded. "Mmh, clever boy. Now just relax and do what comes naturally. As long as you have a good time, I will to..." she purred, giving the ear she'd been speaking into a playful nibble, and causing his own teeth to gently nip the stiff little nub he was suckling on.
"Now here's why I like boys - just came a minute ago and he's already eager for more..." the panthress said but this time Trevor got the impression she was addressing the room. He couldn't really pay attention since at that very moment the panthress was gently lifting up the tip of his shaft, which had apparently gotten hard once again without Trevor even noticing it.
"Yeah, but if you let them finish growing..." a male voice from the crows suggested.
"I think quite a few grown men in this room would be happy with what I'm holding here. I certainly know I am..." the panthress tossed back, causing the adults to burst into laughter with her remark and Trevor to freeze in place when he felt her guide the tip of his shaft to something soft, moist and ever-so-warm. The colt didn't need to guess what it was his flare was pressed against, and it was with some reluctance that he released the feline nipple and craned his neck up. Slitted eyes looked hungrily at him through long lashes, but the panthress' expression was nevertheless one of loving patience.
"Go on Trevor! You don't want to keep a lady waiting..." said someone, possibly his dad, but Trevor barely even heard it.
"Don't rush him! This is a big step for the boy and this lady knows there are things worth waiting for..." Olivia replied, and the room fell silent enough for the colt to hear his heart beating as he stood frozen, the blunt tip of his cock pressed against the feline sex just hard enough for her lips to kiss the flared end. He could feel the panthress toying with his mane, seemingly content to let him take this at whatever pace he was comfortable with.
Taking a deep breath to steady himself, the young stallion kept his eyes down as he very carefully began to push forward. Olivia had one hand resting under his shaft, making sure to keep him in place as the folds of her sex gently parted, the boy gazing in awe at just how much the glistening cleft was widening, until the feline femininity seemed to close around his glans and draw it into the slick honeypot.
His breath was driven from his lungs as he saw his head slip into the purring panthress, the rich, soft moans she'd let out seeming to trigger something within his mind he'd never know he had. His ears were still perked, the moan ringing through his head as he bucked his hips, sheathing half his length into that heavenly slit and earning himself another moan from Olivia, and another round of oohs and aahs from the crowd.
Never in his life had the colt imagined something could feel as good as the feline love-tunnel hugging his throbbing length. He was amazed how something gripping him so hard could also feel so incredibly soft, the warmth of her so enticing that the colt had sheathed every last inch of his shaft into her before he even knew he was doing it. But no matter how much of his length he fed past those splayed lips or how quickly he did it, the voluptuous feline looking down on him seemed delighted, eyes sparkling with mischief and seeming to urge him on.
He was still lost in those eyes when Olivia's muzzle lowered, her lips pressing against his softly at first but then firmly as she gave him a deep, passionate kiss. The colt still had his hands on her chest and he could feel the fingers digging a little into the heavy mounds as his whole body stiffened just before every part of him save one seemed to melt. He could feel the rough feline tongue slip into his mouth to play with his own, and by the time the panthress broke their kiss his tongue was still sticking out a little from his open mouth.
"Come on my little darling, time to become a stud...' the panthress husked and then did something that made her insides clench around Trevor's shaft, making him instinctively buck against the feline's crotch even though he knew he couldn't get any deeper.
A shuddering breath was torn from his as he slid out, watching in amazement as his colthood reappeared, every inch glistening under the panthress' nectar as her lips clung lovingly to every bit of equine flesh that left the warm confines of her sex. When he was about half way out, the colt began sheathing his rod back into the dripping sex, intending to go slowly in case he hurt Olivia, but winding up bucking his hips and driving the last few inches of his young cock into the slick feline femininity.
"Ooh, that's it baby, don't hold back. Let me feel everything you've got..." she cooed, the rich voice sliding into the colt's ears and seeming to bypass his brain as his body followed the amorous plea.
His eyes remained glued downward, his young mind still trying to get to grips with the fact that he was inside someone, let alone a naked beauty that kept making the most indecent noises he'd ever heard every time his shaft slid in and out of her increasingly messy sex. He was aware of his hands flexing in time to his thrusts, fingers digging a little into the two heavy mounds he was still groping, the feel of the panthress' stiff nipples against his palms only adding to the already overwhelming thrill of his first ever rutting.
"That's it sweetie, just keep your strokes nice and deep..." a voice from somewhere nearby said, and it was only when Olivia replied that the wide-eyed colt realized why it had sounded familiar.
"Mpfh! Talk about an -aah!- overbearing mother..." the panthress tossed back, her voice breaking a little as the young stud's efforts got her more than a little worked up. The next thing Trevor felt was a firm hand on the back of his head, and a second later his muzzle was buried between the magnificent feline teats, the scent of the ebony cat's breasts filling his lungs now that his nose was buried in the soft fur between them. "Don't mind her my little stud. I'm yours today, any way you want me. Just don't -mhh!- hold back..."
Trevor didn't really think he had been holding back, but the panthress' words seemed to push him to try and go further. He couldn't imagine anything feeling better than the sensation of being buried inside that warm, wet love-tunnel one second and sliding out of it the next, but as he shortened his thrusts and increased his tempo he realized there was a level of pleasure beyond that one.
Soon the colt was huffing into the feline cleavage as his hips sped up, the slick shaft now pistoning in and out of the feline sex so fast he could no longer tell when it was moving in and when it was sliding out. There was only the friction, the feeling of Olivia's velvety walls caressing every bump and vein on his cock as the sounds of their rutting got increasingly messy. He could no longer smell her perfume, his nose filled just by the sweet, natural fragrance of the gorgeous female purring and cooing as he humped away between her shapely thighs.
It was the purring that got him - a deep, steady rumble that moved from somewhere deep within the onyx feline, through the walls of her sex where they made him feel like a thousand tiny fingers were caressing his length. For a moment it felt like the cunny wrapped lovingly around him had grown just a little more snug, and when the moment didn't pass and he felt things tightening up bellow his waist, the young stallion realized what was about to happen. Warnings swam up in his mind from the special classes they had about all the things a responsible couple should do before getting this far.
"I'm... I'm..." he tried to warn the panthress, only realizing how out of breath he was when he tried to use some to speak.
"It's okay baby, I'm close too... Just come inside me, Trevor. Fill me up and let me feel what a young stud you are. Like that, baby... just like that..." the panthress gasped, and her strained voice was exactly what the colt had needed to hear.
The sopping sex seemed to grow just a little tighter, and Trevor felt himself jabbing his cock as forcefully as he could even as his sack pulled up and the equine length began to twitch. When he gave his last thrust his legs almost gave way under him and he clung to the ebony beauty holding him tight and cooing into his ear. He could feel himself draining away into her, his cock pulsing and sending ropes of warm, virile colt seed deep into the panthress body. The moans she was making rose in pitch, the rich, deep voice climbing until Olivia came around his flared cock, driven to her own climax by the sensation of the young stud emptying himself into her eager cunny.
The colt was still breathing heavily into the downy fur covering Olivia's bosom, the sensation of her sex pulsing around him and milking his already squirting shaft failing to make him pass out, if only barely. He had no idea how much time had passed, and could barely remember where he was or what he'd been doing before he'd began breeding the sultry feline still purring as the last of his seed drooled into her welcoming sex. He only returned to the real world when a finger slipped under his chin, pulling his muzzle up to meet Olivia's own. 
He could hear the cheers of the crown and wondered how long they'd been doing it without him realizing. It did make him feel a little self-conscious, although not nearly as much as a naked boy standing in a room full of grown-ups (and in one of the grown-ups!) should have felt. When Olivia released him from the kiss he took a step back, the still firm length sliding past the well-bred feline folds as the crowd watched on. Trevor was shocked at the size of his flare when it finally popped out, stretching the feline slit lewdly just before it did and letting a stream of equine spunk pour from between the parted lips.
"I can't believe... still hard?" the panthress panted, sounding genuinely surprised while she cupped Trevor's shaft, as if checking if her eyes were lying to her.
"Could it be you're losing your touch, Olivia?" one of the women teased, not bothering to hide the way she was ogling the equine length dripping in the combined juices of the two lovers but still refusing to retreat into its sheath.
Trevor wasn't sure why they were surprised. In the past few months, he'd been getting stiffies at the sight of any female he found attractive, and ever since the panthress walked through that door his mind had been presented with carnal scenes that he'd never even dreamt of. The most recent of which was the thoroughly rutted slit dripping his spunk as Olivia kept her shapely legs parted and the messy slit on full display. How could they expect him to go down?
"Honey, I'm yours for the rest of the night, but I'm afraid I've given my all. So..." the panthress said hopping off the table and walking on to the middle of the carpet before getting down on all fours, her rump facing the still panting colt "...if you want any more, you'll just have to help yourself." she finished, lifting her tail up and out of the way.
Trevor had been eager for more even before his eyes caught the sight of the gorgeous feline presenting herself for him like a bitch in heat. His hooves seemed to move on his own, bringing him closer to the buxom feline as his cock once again grew fully hard, aching to burry itself in that already messy honeypot. As he knelt behind her Olivia spread her knees apart, lowering her dripping cunny to the perfect height for the colt to stuff himself back in.
The young stallion had been awed by the beauty and the presence of the ebony feline while she was looking down at him with that gentle-yet-hungry look in her eyes. But the sight of a female on all fours in front of him, waiting for him to take control and to take her stirred a part of the colt's psyche that knew what to do in a situation like this.
Despite a surge of confidence coming from somewhere, the colt's hands were trembling as he laid them on the round black rump, his fingers squeezing gently at first and then digging in to the lush cheeks. The purr that earned him was oil on the fire, and it seemed to Trevor like his body was moving on its own as one hand moved to grip the base of the thick, black tail while the other one held his shaft. He pressed the tip against the mess still drooling from between the feline lips, and surprised both himself, the panthress and the crowd of spectators by sheathing his entire length in the blink of an eye.
"Oh to be young again!" came a male voice from the crowd, followed by a female adding "Oh for you to be young again!"
But it was the noise Olivia had made that had Trevor's ears flicking, a moan that was close to a throaty feline yowl as her back arched and her well-bred sex tightened around the slippery rod now hilted inside it. The colt shuffled a little closer, keeping a firm grip on the panthress' tail as he felt his length shift within her sex. He pulled out as far as he could, a slow slide before he once again buried his entire length, the soft fur covering the onyx cat's behind failing to muffle a clap as his hips met her lush derriere.
As rough as the stab-like thrust was, the eager feline just arched her back even further, thrusting her rear out and putting herself at the young stud's mercy. It seemed at once as an act of submission and a challenge, and Trevor rose to it, setting a punishing rhythm as he began to breed the panthress for the second time. The rougher he got the more eager the noises the beautiful female clenching around him made, although some of them were drowned out by the squelching sounds of his pistoning cock pushing his still warm seed out of that feline slit. Not that it would matter, since the sack swinging between the colt's legs still looked like it had plenty left to pump into that pulsing love-tunnel.
The colt was grunting with every thrust, his humping savage enough to make the panthress heavy breasts swing under her as every smack of his hips against her heart-shaped ass pushed her forward a little. The sultry feline couldn't believe the young stud's energy, even though she was feeling every bit of it as the child rutted away as if he'd done this a hundered times before. Her slit was sensitive after just having that magnificent young cock breed it so thoroughly and she found her body responding to the feral fucking more quickly than she'd anticipated. Although she suspected part of it was just a pleasant shock from being so forcefully dominated by the adorable colt.
Trevor's eyes were watching the ripple of that perfectly-rounded behind as he humped against it, as well as the jiggle of the feline's majestic teats hanging from her chest and looking even bigger than they had when he had his head between them. His mane had fallen over his eyes without Olivia to push it back behind his ears, his chest working like a bellows as he rutted tirelessly, without any idea where this energy was coming from.
His gaze traveled up along the voluptuous feline form, noting the way the muscles of the panthress' back were tensing, just as the ones wrapped around his length were doing. When he reached the spill of thick, inky hair covering her shoulders, an idea seemed to pop up in his head, and before he knew it the colt was reaching out towards it.
Olivia was surprised to feel fingers tangling in her mane, and even more when the thick locks were pulled taut as the young stud mercilessly rutting her messy sex yanked her head up. With her neck bent back the panthress' shaking chest was thrust out, her expression of surprise and delight on full display for the equally surprised crowd. The feline had enjoyed her share of boys, but not a single one of them had even tried something like this! With one of his hands gripping her tail and the other pulling on her hair, she was at the young stud's mercy, and it was that realization that pushed her over, her speared sex gushing around the length pistoning in and out of her with every last bit of strength left in the boy.
When he felt the snug passage he was rutting pulse and quiver, Trevor knew he wouldn't last long. He found himself clenching his jaw and making strange growling noises as his pace became erratic. Half the time he was barely pulling out, and just grinding his crotch against the feline slit as his tip once again flared, making sure that the panthress still cumming around his cock took every drop he pumped into her. When he finally felt his cock twitch and send the first spurt of his seed surging into the stuffed feline slit he released Olivia's tail and brought his hand down on one soft cheek, groping it possessively as he painted the panthress' womb with another coat of colt spunk.
The last bit of his strength seemed to flow out of him along with his cum, and the colt was thankful for the hands grabbing him under his arms and holding him steady. His body seemed to know it had pushed itself to far, the length sheathed inside the purring cat's cunny softening and oozing the last few drops of the spent colt's cum before the flare slipped out.
Part of him wondered if he'd gone too far and played too rough for Olivia's liking, but after he was out the panthress rolled over onto her back, a smile gracing her muzzle as she beckoned for him. He could feel someone draping him over the panthress, the softness and warmth of her body against him seeming to drain the last atoms of strength he had left. His eyelids felt like they'd suddenly turned to lead, and as the colt rested his head against the pillowy feline breasts, he lost the fight to keep them up.
"Best... birthday..." he said weekly, lulled to sleep by the black cat's happy purring.
