Curiosity's growth (NSFW)

Written by © Reeden Landshey

"Are you sure about it? Mom and dad always told me not to enter their lab when they are away, no matter what!"

"Of course I'm sure! As usual, they are keeping all the best secrets away from us! Like we're not skilled enough to give all those spells and potions a proper use. We're not cubs anymore!"

"But... It's not too far from the truth! I mean, after all we're just teens, and we've finished only the first class of chemistry and practical magic usage."

"Hey! We're here because of your curiosity, remember? You were the one that asked me to break into the lab, so we could just dwell around. Or maybe you are chickening out?"

"Of course I'm not!" A 12 year old female snow leopard with bright, purple eyes and black & white hairs, with ponytails on both sides of her head, made a frustrated expression on her muzzle, crossing arms. "I don't want us to get punished, or mess up anything in the lab, that's all! Also, your dad won't be happy when he'll find out that you skipped today's class in the library!"

"Yeah, you're definitely chickening out." A cougar male - being at the same age as his snep friend - chuckled, examining the heavy, wooden doors with his paw pads, and ignoring words about his dad. His eyes were the same color as leopard's, and he had an unusual black, thick mane on his head and back. Placing his ear against the door's surface he closed his eyes. "Hmm... Not too much of the security spells. I think your parents wanted to scare you away from the laboratory, telling you some fake stories."

While her parents were famous State Magicians, his dad was the chief scribe in the Great Library of Carmond. They were always following rules and protocols, not having a single thought about doing something against them. And of course they tried their best to pass those "precious" moral values and boring rules to their kids.

"They would never lie to me!" Freya said loudly with resentment, unconsciously clenching her paws into fists. She was so tired about Reeden's self - confidence. "I'm sure they didn't..."

"Aaand it's opened." Reed pressed down the handle, pulling the heavy doors toward them with a silent growl as they were way more heavy than they looked."Come on, just a little more!"

As the door opened enough for two teens to sneak in, Reed and Freya quickly entered the lab's room. After the cougar closed the wooden wing silently, he glanced around all the tables and shelves, letting out a rather loud "wow". He couldn't feed his eyes with all those colorful vials and old scripts. It was so different from what they saw in the school! Not to mention that the whole apparatus was way more advanced! Also, it seemed that some of the potions were left for slow brewing. Taking a closer look at the vials and the liquid inside it, Reeden noticed that the fire's source wasn't from an oil lamp or coal. Flames, which were changing from blue to green, seemed to be a fully magical one.

"How is it possible that you haven't sneaked in here for so many years?" He asked, locking his eyes on the book that was currently floating in the middle of the lab and its sheets were slowly changing. "I never thought that the State Magicians are on such a different level than our teachers!"

"L-like I said, mom and dad never allowed me to enter their lab." Freya seemed to be upset, discovering that she knew so little about what her parents were doing. "I didn't want to risk, since they were always scaring me with all those security spells and potential side effects of..."

"Woah! Have you ever seen such a potion? It has such a cool color!"

Young cougar wasn't really paying attention to the snow leopard's words, already taking off one of the large vials from the unsigned shelf. Substance contained inside it had a dark red color, but when Reed shook it lightly, it changed into the orange one, with white and black veins mixed into its structure.

"NO!" Freya screamed, quickly noticing the spot that cougar took the potion from. Even though she wasn't allowed to enter the lab, her parents were always talking between each other about that one, nameless and special shelf. It contained spell scrolls and potions that were freshly discovered and still needed to be tested.

But it was already too late. Before she was even able to stop the young puma from vial's shaking, sudden mixing of its content made the glass extremely hot. Reed screamed with pain as the vial started to burn his paw pads. Without even thinking about it, he dropped it on the floor, and Freya could only watch as the round vial fell down. At the exact second the glass walls made contact with the cold stone floor, it exploded like some kind of small bomb, shattering into thousands of pieces. The liquid that was contained inside instantly evaporated, in just a few seconds filling the whole lab with a thick cloud of orange-red-black smoke and reducing visibility to the minimum as the explosion's shockwave extinguished the candles - even if the fire was a magical one.

Pretty fast the smoke started to bite Reed's and Freya's throats and nostrils as they started to cough and sneeze, only inhaling more of the evaporated potion into their lungs.

"Look wh - what have you done!" Snow leopard choked out of her in between coughing. "M- my parents are going to kill me and... Use me as their magic ingredient!"

"J- just don't panic!" Cougar muttered, still in mild shock after the explosion. The smoke felt like it was invading his insides through his throat and lungs, somehow merging with his body. Was he hallucinating because of the lack of fresh air? "We need to find the window and let that smoke out!"

"I think that there's s- small window on the right side of lab." Freya finally calmed her breath and thoughts, promising to herself that she'll scalp Reeden alive from his fur if she'll make it all safe from that mess. "I'll open it, but you need to open the lab's doors, so the air can circle faster inside".

Covering her muzzle with the upper part of skirt, the snow leopard went into the direction she remembered the window should be. Suddenly she started to feel a little dizzy and hot as her body probably was screaming for the air. Her skin under fur started to feel all itchy as well. Was that some kind of allergy? Hoping that it'll pass soon, she moved forward slowly, reaching with paws in front of her almost like a blind cat, hoping that she won't accidentally hit more shelves and vials. Freya's ears were moving from time to time too as she was worried about Reeden. Has he already reached the doors?

Eventually she reached the lab's wall and the small window. The latch was moving with a bit of difficulty, but Freya found - with a little surprise - enough strength to push it to the side and open the window. A sudden wave of fresh air washed her muzzle, pushing the magical mist deeper inside the lab, which meant that cougar managed to open the doors as well. That was a success indeed, but... Why couldn't she get rid of that annoying overheating of her body? It was really hard to think about any explanation to her parents when almost every part of her was in flames. Grunting silently, she went back into the middle of the lab, slowly putting together a plan inside her head. It was an accident, I'm sure about it! You've placed the vial crookedly on the shelf and that's why it felt down and broke....

"I opened the doors as you asked. Hopefully it'll help out with airing the whole lab. Umm... Is... Everything okay? You look... Different?"

Reed didn't know how to describe the view he currently had. As the magical cloud started to fade because of the air's movement, he could finally have a closer look on Freya. Cougar could swear that her favorite orange skirt wasn't usually fitting her whole frame THAT tight. It looked like snep's body filled her clothes in a mere minutes, pressing against the fabrics, maybe even stretching them a little. What could be the reason for such a sudden change? It was really hard to put his thoughts into any rational direction as he just couldn't take his eyes off his friend.

"Different?" - She asked, raising her brow. "I don't know what you are talking about, but yeah, everything is fine. It's just... Really hot here." She replied, pulling her dress collar nervously. Her eyes were locked on the cougar's chest and shoulders. Was his shirt usually fitting them that tight? Not to mention his height! He was always smaller than her for at least head's size, so seeing him somehow matching her was... New.

"Y-yeah... Really hot..." Reeden huffed silently as his skin and every single muscle of his body started to itch and burn in an odd way. W-was he expanding like some kind of a balloon? Somehow, with every extra inch that he was gaining, male feline was feeling more lightheaded, caring less about the changes that were occurring in his shape. His shoulders had become wider, making room for a sudden muscle burst on his back, and his arms were fast to become larger too. Chest pushed forward against an already tight shirt, and the first signs of forming ABS could be seen on the cougar's belly. His legs were getting longer and more muscled too - his thighs became way more firm, and the same went for his calves, all that to provide a certain support for his growing body. His shorts - already stretched from hips and rear's size change - were pushed to the limits even more as the bulge in the middle of it became way more visible, expanding faster than other body parts.

Opening his muzzle, the cougar started to pant as the changes overwhelmed all of his senses, while his head was filled with complete chaos. Fear, surprise, pleasure - they were all mixed up, same as the sounds that accompanied rapid changes. Reed's bones were cracking while adjusting to a new body size. His clothes started to rip on the seams as the mass of muscles and fur were just too much for its current dimensions. And on top of that, a murring and growls started to escape the feline's throat, getting louder and deeper with every minute of passing transformation.

To sum it all up, the cougar's body was adulting up at an unnatural pace - with every minute passing, he was 1-2 years older. The same thing was going with his brain as the young teenager's thoughts were replaced with something that was still shaping out. Something surely more adult... And needy. Despite all the mess he was currently in, Reeden's pupils were narrowed and focused on Freya as his eyes were hungry to see her changes as well. Just thinking about all the leopard's transformation she could go through was warming him up, and those thoughts were mostly the cause that his shorts became more like really tight underwear, pressing against a rather large looking sheath and balls.

Freya - in the other paw - was keeping her eyes focused way too long below the cougar's waist, biting her lower lip. Was it because of the view she was currently having? Or maybe her own changes were driving her nuts? Surely there was so much to handle by herself. While Reed's body was reacting with the magical smoke, so was leopard's, rewriting anything that her world stood for until now. Her fear about the consequences of sneaking into her parent's lab was pretty fast fading away, replaced by other priorities. She couldn't help it - moving closer to the growing cougar, she reached with shivering fingers to examine inches of his swelling muscle mass, opening her muzzle and letting out a silent huff.

While snep's paw pads were going through Reed's hardening muscles, starting from his widening shoulders and swelling biceps, she grew as well, clenching her expanding thighs together almost instinctively, feeling the burning heat in between them. Freya's height followed the cougar's one pretty fast! She wasn't gaining as much muscle mass as he did, but her feminine attributes were now big enough to tear her dress here and there. Her breasts ballooned out, pretty fast switching their cup size from A to a double D and going even further, pushing against the middle of the feline's dress seams and there was no telling where she'll stop. Female's nipples puffed out too, pressing against the soft material, only stimulating her more. Suddenly she let out a loud moan as her asscheeks, hips and thighs widened, almost tearing her dress lower part into the shreds.

Biting her lower lip, Freya couldn't resist it anymore - moving closer to still growing cougar, she pressed her already heavy - looking tits against his hardening torso, trying to lock her eyes with his. Leopard's claws slid from his athlete's back and sides, digging deep into his fur through the shreds of his shirt. She could feel his whole body bulking out, still expanding muscles pressing against his skin, his ABS popping out even more and pushing against her belly. How old were they already? 15, 16, or maybe 18? There was no answer as the magic was still taking a toll on both of them, already putting both of the feline's parents into shame. While Reeden already surpassed his father's whole's body build, Freya did the same to her mother... Not to mention she was already higher than a cougar for at least half a head's size.

As the snow leopard's body pressed against his, the cougar male felt an unusual, tingling pleasure that was new to him. Snapping out from the current flow of changes that they were fogging his mind and focusing on Freya, Reed opened his eyes wide. She was already so tall, even taller than him! Not to mention her body proportions were currently exceeding an average one of an adult snow leopard's female. A feline gal that was currently gently grinding against male's body wasn't comparable to her parents at all, like something other than genes was taking the lead of the current transformation. Cougar's orange eyes couldn't decide on which part of Freya's body he should focus more - breasts that were barely covered with shreds of her dress top, or the rump that was already hard to grope with one paw. Also, when she was close, Reed could clearly smell a new, intense scent that was mixing up with the usual Freya's sweet one. And somehow that scent was pushing away shreds of his teen's mind, making him less worried about the lab's accident and focusing on other priorities. It was growing and changing together with his body, with every passing second.

"F- Freya..." Cougar muttered, while his paws - guided more by instinct than his own will - reached forward, gently pressing against the leopard's arms and slowly sliding down, removing shreds of clothes that were still on her body. His paw pads were examining her silky soft fur and warm skin, discovering that she gained some muscle mass under it as well, going through her back and hips. "What's happening to us? I... I can't control it." Or maybe he could? But the more he wanted to be in charge of his own body, the lower his paws were going. Within less than a minute sharp cougar claws digged into Freya's round rump, drawing quite a lustful moan out from her throat. And somehow that sounded delightful for him, like a reward for a job well done. But... He wanted more, not only touching her! Moving his muzzle closer to snep's breasts - which already reached the size of a plump watermelons - Reed gave them a few, slow licks with his rough, feline tongue, focusing especially around her already puffy nipples.

"Rrrrrfff..." A deepening growls and huffs were escaping Freya's throat. While Reeden's changing frame already surpassed most of the kingdom's knights, making his back formed into a perfect "V" shape, her body proportions became something between an adult mother and a trained female, still exceeding cougar male for at least head's size. While she reached a solid 3 meters height, he was about 2,60 m. "R- Reeden...", she called out her friend's name with a voice laced with burning need and lust as her whole body shivered, feeling the gentle, yet teasing touch on her body and breasts. "W- we need to stop... It's not r- right..." Feline gal mumbled with her mind struggling to keep everything together, while Freya's adult body was quite the opposite, greedily craving for more.

Her own paw slid down through the exposed, rock hard pecs and firm ABS, passing through the thick pubes, only to discover that his sheath was already hot and pretty stiff. Her paw pads circled around it shortly, coming across the barbed tip that was peeking up from its hiding, leaving a warm, sticky matter on the feline's fingers. Fighting the urge to raise her paw up to smell it or even lick it Freya bit her lower lip, moving her fingers lower to the cougar's balls, which already reached the size of a grapefruit each. "Gods... How can you be that big already?" She said, cupping them instinctively. She could examine how heavy and full those orbs became, almost audibly sloshing while snep was toying with them in a rather teaseful manner, with a deep murrring escaping her throat. They were surely gaining potential to put a heavy shots of fertile semen inside her, making her pregnant with his strong cubs...

Leopard female shook her head, surprised by her own thoughts, pulling her body back a little and lowering her ears. How could she even think about something like that, in the middle of her parent's lab? And with Reeden, her best friend? She was always taught that when she gets older, a male that was born in a family of high rank should seek her attention and marry her, so they could be together for a whole lifetime, having a bunch of healthy kids. Freya's parents may have liked Reeden and his dad, but would they allow a son of a scribe - even a higher one - to be her husband?

All those thoughts blurred out immediately after she was turned around and bent over against the potions shelf, making the vials twang silently as the leopard grabbed it for balance. She may have been bigger than a cougar, but his body build was allowing him to move her body with surprisingly ease. His claws slid out, digging around her tail base and sliding through her butt. A deep, manly growl could be heard as he suddenly kneeled behind Freya, groping her ass cheeks and spreading them. "R- Reed?" She gasped in shock when Reed grabbed her thick tail, lifting it up to expose the feline's tailhole and her fully formed inner lips. They were already swollen and moist because of the body excitement that was already out of leopard's control. Shivers went through all her back as the cougar's muzzle moved dangerously close to her sensitive areas, leaving his breath on her entrance and inner side of thighs. "W- what are you do... Oooohhh..."

Her question was cut in the middle as Reeden's nose bumped against her lips, inhaling the scent of adult feline in heat. Freya wanted to turn her head back and see what her male friend was doing down there, but instead she moaned loudly as the rough feline tongue brushed against her pussy's lips. They were really sensitive, sending waves of new pleasure to her whole body, pushing the last pieces of her hesitation away. When the cougar's tongue slowly passed through them and started to brush against the top part of her vagina's muscled walls, the leopard's claws slid out and dug deeply into the shelf's wood and another, more lustful moan escaped her muzzle. Hopefully she was tasteful enough for him, because she didn't want him to stop at all! No wonder most of her female friends wanted to grow up as soon as possible to experience the adult's life.

As for Reed, the taste of her vagina wasn't comparable to anything he knew, but still it was the most delicious thing that his muzzle ever felt. And there was so much of a sweet nectar dripping out of it! The fur on his muzzle was already soaked with her scent, so there was no way to escape from it. While the tongue's rough surface was brushing against the leopard's inner walls, the cougar's fingers were pushing against Freya's asscheeks, trying to knead them as much as he could for mutual pleasure. They were already big enough to cover his muzzle in between them! Letting out a deep murring from his chest and making the feline's tongue vibrate, the cougar opened his muzzle wider for better and deeper penetration, almost digging his sharp teeth into the female's juicy ass. His newly shaped muscles were eagerly screaming for action, already being tense and throbbing under his skin, Getting just a taste of Freya's dripping sex was currently not enough, he needed more! Moving his head back, Reeden cleaned his own muzzle with long, slow licks, leaving Freya's pussy all warmed up and dripping. A deep growl started to escape this throat as he slowly stood up from his knees, keeping his paws on the leopard's ass.

"Nnnfff... W-why did you stop..." Leopard muttered as cougar slid out his tongue from her needy vagina. She was deeply lost into the new ocean of pleasure she never felt before, so the sudden pause in the current flow of action felt unnatural and unpleasant, like tearing off someone's clothes during the cold day. Her head turned around to see if everything's okay with her friend, but instead she gasped loudly. There was no more a 12 years old cougar teen that was smiling shyly around her. Instead, her eyes were sliding through a frame of a muscled feline stud who just turned 30, and there was not a single shred of clothing to cover it. Though the size difference between them remained unchanged, and Reed was still at least head-size shorter than her, his muscles were ripped and fitting tightly under his skin and fur. Even the mightiest of the kingdom's heroes could be envious of his figure! Male's large paws were currently roaming through Freya's body in a really gentle manner, but she was sure that Reeden could do whatever he wished to her at any time with almost childish ease.

Going down quickly through the rock hard pecs and ABS, the feline's pupils stopped on the spot that her mind and body were currently devising the most. Reed's dark-orange, barbed cock was throbbing lightly in the lab's air, with veins already exposed on its foreskin. Round, filled balls were sagging low below it, giving quite a promising potential of leaving a few large loads inside her needy cunt. And Freya needed those loads badly, shot deeply inside her womb and being sprayed all along the leopard's body and fur, getting marked with cougar's scent. It might sound strange and greedy, but she wanted to be his property only, being covered with his addicting scent

"Oh gods... Just put it in already!" Female moaned loudly with nothing more than a pure, desperate need, reaching with her paw to place a soft grip around Reeden's member, and pressing its tip against her already puffy and moist entrance. She didn't care about the lab, her parents or the potential potion's side effects anymore. All that she needed now was a feline's cock shoved deeply inside her pussy. Biting her lower lip, the leopard slid a barbed tip through her vagina's lips, hoping that Reed will take up a lead from there.

And he did. Gripping the leopard's hips for better guidance and digging his claws into her body a little too hard, the mountain lion slid his length inch by inch inside the female, with sharp barbs grinding against her sensitive inner walls and additionally stimulating them. He wanted to go slow and gentle, enjoying the moment without any rush, but his instinct took over pretty fast, making him shove his whole 16 inches of throbbing meat inside her. Freya screamed from the depth of her lungs because of unusual and sudden pain as Reed's cock broke through her virgin's entrance, giving her vagina's quite a tight fit with his manhood. Her muscled walls clenched around the cougar's cock violently, making male stud hiss loudly - it felt painful for him... And pleasant at the same time.

"Are you... Rrrfff... Okay?" Reeden asked, trying not to fall into the trance that his mind was currently slipping in. Give her all that you got... Break her... Knock her up... Make her full of your seed... Mark her... Cougar shook his head, pushing away the sudden rush of intrusive thoughts. He didn't want to hurt her, even if the chance of it was pretty small due to their size difference. It felt heavenly for him, being milked with her muscled, pulsating inner walls, but was Freya feeling in the same way?

He found the answer quickly enough as Freya's fingers and claws placed a grope around his muzzle, directing it to make eye contact with her. Leopard's eyes were burning with nothing more than lust. "Nnnffff... J... Just fuck me!" She ordered loudly with a deep voice, licking her own muzzle slowly. "Give it all to me Reed! Mmmhhh... Breed me! Make me a proud mother of your strong cubs...", she encouraged him, pressing her asscheeks against male's thighs, fitting his cock balls deep inside her cunt. That's right... All that she needed now was his warm, potent semen. The thought of becoming a mother to the strong, feline hybrids was arousing her even more.

Receiving permission - or rather an order to act, Reeden didn't waste his time. While his paws kept a firm grip on the leopard's hips, he started to rhythmically move his body with slow, yet deep thrusts. His barbed cock was welcomed with a tight, warm grip of Freya's inner walls, and yet it was slicking inside her smoothly, like it was always meant to be there. Cougar's filled orbs were swaying with each move of his body, already having a potential for a whole night of breeding. Each strong thrust was making the shelves that Freya was clenching into to shake, glass vials clinking against each other. Her heavy breasts were swaying in the rhythm of thrusts, and their perky nipples became extremely sensitive to the slightest touch or even air movement inside the lab. Opening her muzzle, she started to pant and moan - her whole body was on fire and currently calming it down was out of question.

"F-fuck!" Leopard exclaimed, feeling that the swollen feline cock was spreading her inner walls to their limits, with tip pressing each time against her cervix. Freya reached down with one of the paws between her thighs, starting to massage her clit with a paw pad. "That feels s- so good... N- need... MORE...." She said as her head lifted, taking a closer look on the shelf in front of her, trying to focus her thoughts in between the loud, wet plaps. Pretty fast, her eyes found the vials marked with the same, runic label that they broke, bringing a sly grin on her muzzle. Actually, there was an easy way for them to have more! And the leopard female didn't consider that option for too long. With a "careless" move of her paw, she threw two more potions off the shelf, making them break against the floor.

Before Reed could react somehow to the sound of breaking glass and another magical cloud that filled the lab's interior, Freya pushed him away, leaving his swollen, damp "spear" exposed for the fresh, chilly air. He growled deeply, wanting to protest against such a sudden change, but soon enough the cougar's mind and eyes were filled with quite a show - the leopard's frame suddenly gained another boost of femininity and muscle's mass, expanding in every direction. As her height increased by at least half meter, each part of Freya's body sized up proportionally, starting from heavy tits, going through a more firm belly with first signs of ABS, and ending on the thighs that could easily crush a cougar's head between them. Soon enough the cougar was pressed down against the floor's stones with the snow leopard's weight, while she quickly reached four meters of height, outgrowing shelves and going dangerously close to the ceiling. Her body build was now a perfect mix between an adult, curvy girl and a trained female soldier - there was so much of her frame to grope, but it would be risky to do it without her allowance. Her look became more wild as well - leopard's fur grew thicker and longer along with black and white - highlighted hairs, which were currently in quite a mess, already reaching half of her back.

Reaching down with a burning need that was pushing away any reasonable line of thinking, Freya wrapped her large fingers around Reed's throbbing cock, guiding it back inside the female's milking walls. She let out a pretty loud, lustful moan, feeling the cougar's barbs pressing against her sensitive vagina's walls. At first it seemed that the cougar couldn't keep up with all those sudden changes as his dick was going inside the leopard way too smooth. But soon enough his body followed Freya's one, suddenly bulking out under her as well. Cougar growled loudly as his paws started to have an easier access to the leopard's curves, while her moist pussy was giving his cock more snug fit with each bounce. Soon enough it was hard for her to have all of Reed's length, which only made the female more frustrated. Digging her fingers into the floor on male's sides and shredding its wooden surface with unnatural ease by her claws, Freya was riding the cougar's dick ruthlessly, simply craving for his seed. Her round ass was going down, each time finding out that his balls were larger by every second, soon enough passing the size of a ripe watermelon each. And she could clearly hear that potent genetic material gurgling inside them, demanding to be released and giving birth to a herd of strong cats.

"That's right Reed... Give it all to me... Knock me up with your semen..." Snow leopard demanded, licking her own muzzle with delight while humping Reed's cock as much as their sizes were allowing them, lifting her body high only to descend it low on a cougar's throbbing spear. Sloppy sounds were filling the room along with glass rattling, while the whole lab was shaking under two large body's movements. Her back was already pressing against the lab's ceiling, but Freya wasn't minding it anymore. Destroying those walls... Anything that was bounding them to this place was only turning her out more. Her moans were becoming deeper with each size change, empathizing with the fact that she was becoming larger... Stronger... And more needy. Pretty soon her heavy, milk-filled tits were wrapping around Reeden's head, her nipples were close to spray the nutritious liquid under the slightest touch.

"Rrrfff... G- getting so close..." Cougar muttered with a deep, manly voice, feeling that he wouldn't last too much longer, especially with the muscled leopard's inner walls, which were clenching around his cock insanely tight. His claws dug deeply into Freya's marvelous ass cheeks, shredding through her skin. Snow leopard's juices were mixing together with male's pre for a perfect lubrication, allowing Reed's barbed tip to invade the female's womb, spraying all along their thighs and his heavy balls. Those round orbs were pushing tightly against the cougar's sack, almost demanding to be emptied. Just a few deep thrust, and he'll be able to...

"Dear Ancients! W- what's happening here?!"

Both felines' heads - guided by a purely shocked voice - turned toward the lab's entrance at the same time, shaking off from the breeding frenzy. They found out that a black panther's female - with some parts of her fur mixed with silver and white highlights - was standing there, holding a linen bag with both of her paws. As her emerald green eyes examined the chaotic scenery, the bag dropped down on the floor, making potions ingredients and herbs inside to roll slowly outside.

"Who are you?!" She asked, baring her teeth. Panther's fingers moved pretty fast as she incarnated a thunderball spell in between her paws . "H- how did you enter the lab?! And why are you defiling its interior with..." Black leopard's sentence was cut in the middle as a white, large paw reached for her, placing a firm grip around her body. She was lifted up with unnatural ease - almost like a living toy - and brought to face the snow leopard's muzzle. "R- release me right now!" She demanded, but there was no point fighting those large giantess fingers - if she would make any unnecessary move, they could break her spine with ease. But when she made contact with purple, slitted eyes, she found something familiar in them. "F- Freya?" Older feline asked quietly, as she couldn't believe it. Was it even possible for her to change that much just because of misuse of the potion?

"Mrs Sally! I - I can explain! We... I just wanted to see the lab from the inside. And..." Reeden seemed to be really embarrassed with the whole situation, as the sudden appearance of the leopard's mother snapped back some senses into his brain. Normally he would hide somewhere or cover himself up, but Freya's body mass was pinning him down to the floor, preventing him from escaping.

"Hi mom!" Snow leopard replied with a smirk. "I'm sorry for the whole mess, but we decided to sneak into the lab and dwell inside it a little" She explained with a carefree tone of voice, while her claws were going through her mother's clothing, shredding them here and there. "As you can see, we can't complain about the results of your potions, while they work pretty well." Freya added, letting out a moan as her pussy was still pressing against Reed's cock. Her inner muscles were milking him without mercy, even if they were going through such an unusual meeting. She licked her own muzzle. "And since you are here, it would be totally ungrateful to keep it all to ourselves, while you've worked so hard on it" Snep female reached with her large paw to the shelf, picking one of the vials carefully with her paw pads.

"Freya... Don't you dare..." Rest of black feline's words were drowned with the flow of the potion being poured into her throat. Her daughter removed the cap in a mere seconds, forcing a bottleneck into mother's muzzle. She growled with frustration, trying to split it out, but it seemed that her daughter was aware of it - she pressed her large thumb against the panther's throat, making her swallow the entire contents of the vial. As soon as it was empty, Freya placed Sally on Reed's muscled chest, allowing her to catch her breath as she was coughing loudly. "W- what have you done?!" Black female mumbled looking at her daughter with fear mixed up with anger. "We haven't tested it out yet, especially how it works when ingested! It can be poisonous!"

"Oh it's quite the opposite mom! Just look how well it worked for both of us." Freya replied, groping her own hefty breasts with paws, and then reaching back to cup one of Reed's ballooned orbs, making him growl. Male's embarrassment was fighting inside his head with a desperate need of cumming as his balls were getting close to burst, overfilled with fertile semen. He imagined unloading all that potent genetic material inside a snow leopard's womb, just in front of her mother and his cock throbbed hardly inside Freya's tight pussy, as that thought turned him out even more. Maybe Mrs Sally would like to have some good breeding time as well? After all, her husband was now nothing more than a shrimp, being compared to Reeden's mighty body. No no no, this isn't right, he said to himself, trying to resist the potion's effects on his mind. But just when he was fighting it, the snow leopard shifted her mother so close to his head that her rear bumped against the cougar's nose.

"Go on Reed, have a taste of her." Freya said in a teasing manner, while she started to move her hips slowly, keeping Reed's cock hard and stimulated with her inner walls. And with those words, a last flicker of cougar's resolve faded away. He slowly locked his fingers around the panther's thighs, pressing a large nose in between her ass cheeks. She smelled different than Freya - it was a scent of experience, maybe a little rusty female, but still it was intoxicating, almost addicting. Before Mrs Sally even tried to resist, Reeden's claws ripped an opening through her robe and his powerful, rough tongue slid in between her thighs, brushing against the panther's rump and inner lips. She gasped loudly in surprise, wriggling as she tried to free herself... But shortly after she her body acted instinctively against her own brain, pushing down more against that invading surface. How much time has passed since I had a good, pleasing time with Rufus? She thought as the potion finally started to mix up with her blood, suddenly making her mind much more relaxed about the whole situation. There were so many spells that she could use to free herself up that they didn't require paws usage. And yet, Sally wasn't rushing herself to use them. Maybe I should have some fun too?

Effects started to occur way faster than for Freya and Reeden. Panther's body began to expand in every direction in a blink of an eye, tearing remains of her clothes to pieces. Sally was expecting a big amount of pain, or a weird feeling of stretching, but it actually felt nice. Unusual, yet a pleasurable moment as her bones were cracking loudly while expanding, pressing more against the muscles, and the growing muscles were pressing tightly against her skin! Not only a minute had passed, and she was already half as big as her daughter, with her body build getting more muscular and feminine at the same time. Each cougar tongue's brush against her entrance was making Sally's mind less concerned about the potential side effects, and caring more about occurring changes as silent moans started to escape the feline's muzzle. Her tits pushed forward, becoming more hefty and round, while her nipples perked out because of excitement. Panther female couldn't help it and reached with both paws to examine her own breasts, feeling how heavy and warm they were. She licked her own muzzle with delight. M - moreeee... Rrr...

Soon enough Reed's rough tongue was able to fit in between her expanding ass cheeks and slid inside the panther's vagina, which started to smell more... Needy, resembling the scent of her daughter. Black feline's insides were already moist and almost burning hot, still reshaping themselves, becoming more roomy and muscled at the same time. And while Sally's body kept expanding - already outgrowing Freya's for at least twenty - or even thirty centimeters, her fur began to regain its density and saturation, becoming a solid black one. It was beyond any kind of imagination, and yet it was happening - the panther was becoming younger! In just a few minutes she regressed from a fifty years old, fatigued mother into a thirty - five female, with all of her needs blooming out once again, burning inside both her body and mind.

The lab's ceiling started to crack as Sally's back and head were pressing against it more intensely than Freya's, while she started to ride Reed's tongue without a trace of resistance, letting out a feminine moan that sounded pretty low, probably because of her new size. "F- fuck yes... Eat that pussy like you mean it, you big stud! I bet my daughter hasn't given you enough fun, since she's inexperienced, but that's about to change..." Panther said, suddenly gripping the snow leopard's shoulders with her paws, digging claws into her fur in a pretty rough way. Sally pulled Freya's body closer to hers with ease - probably because of her new, muscular frame and gained size difference - looking into the purple eyes with nothing more than a burning need, panting hardly, And then, without a slightest hesitation, she kissed her daughter, twirling their tongues together with nothing more than heated passion and need, pressing her breast against the leopard's one, puffy nipples grinding each other, stimulating them to leak some of their sweet, nutritious milk.

Sally's awakened needs triggered the potion's effect on Reeden and Freya as well - their bodies started to grow more, filling more of the room's surface with their curves and muscles, crashing the shelves and lab's equipment like fragile toys. Another two minutes were enough for the feline's trio to break through the laboratory - or rather a whole building's walls, trashing its rubbles under still expanding cats. 10 meters of height... 15... 20... There were no signs of stopping for them anytime soon as they started destroying nearby buildings as well. Other citizens weren't sharing the passion and lewdness that growing felines were currently going into, running away from them with screams that were muffed with growls, pants and moans which sounded now low, powerful, more titanic.

Remains of the labs were now just a memory under the muscled Reed's back, while two large, strong felines were riding him. Both females were still bigger than him - Freya was a head-size higher, with her body's shape being similar to some kind of goddess, including some of muscle mass. Sally's tits - in other paw - were currently on her daughter's eye level, and the panther's muscularity could be matched with cougar's one, without losing too much of her femininity. Reeden's head was almost gone in between panther's ass cheeks, barely having a chance to catch a breath, while his muzzle was covered with her scent and juices. Sally dug her claws into his rock hard torso, being completely lost in her own pleasure, forgetting about the lab and her husband. Her daughter meanwhile was nearly crushing his pelvis as she kept bouncing on his large cock, placing both of paws into her own hairs, letting her large tits bounce in the fresh air, giving quite a show to her own mother and citizens as well. As she was going down like that - each time balls deep - a precum mixed with her juices was spraying around their lower bodies with loud, sloppy sounds, soaking the nearby area with their scents. Her round, yet firm ass kept stimulating the cougar's swollen orbs to produce more of the fertile semen inside them, making heavy feline balls hearable gurgling.

And then, without any warning, Reeden came. While his roar was muffled under Sally's rump, Freya suddenly felt the unexpected eruption inside her. With a cougar's cock being currently balls deep inside and its tip pressing against her cervix, warm ropes of semen started to flow into her womb extremely fast, filling it in a mere seconds and starting to push against her uterus walls. Snep feline opened her eyes wide as the sudden Reed's eruption made her climax just a second later, clenching her inner walls tightly around his cock and milking it without mercy. Her loud, deep roar made the whole city tremble as she arched her back, shredding the street with her claws, with tits exposed proudly into the air. Her eyes rolled upward in a pure bliss, feeling that she was already full with cougar's potent semen. Pretty soon her ABS was gone and Freya's belly started to bulge out, resembling one of those belonging to the pregnant females, but she didn't mind it at all - carrying a whole litter of strong Reeden's cubs felt like some kind of sacred duty for her.

Sally's eyes locked on her daughter with some kind of corrupted pleasure and envy, and she couldn't turn them away. Watching her being impregnated by Reeden made black panther's arousal burn as twice as strong as she bit her lower lip. She was close too, but the cougar's tongue wasn't enough. "Mmmhhh... Be sure to save some for me too, stud", she teased him. Moving away from his muzzle and making sure she was in line of male's sight, black feline placed herself next to the cougar and snow leopard, resting her heavy tits into the nearby buildings rubble, almost creating small craters in the ground because of their mass. She lifted her ass up in the air, wiggling it slowly with nothing more than a tease and a pure need, while her tail moved up too, exposing Sally's dripping pussy's lips and tailhole. Large feline spread her asscheeks with paws, giving the cougar a better look on her sensitive insides. "Go on... Make me full of your cock and cum as well. I need it badly!" She moaned out.

Reeden didn't need any more encouragement. Freya lifted herself up on shaking legs, slowly sliding his barbed cock out of herself with growls mixed up with moans as she was still extremely sensitive, falling on the ground next to them and panting hardly as the stream of cougar's semen started to leak out from her insides, covering the nearby streets surface. Cougar's member was still rock hard, and his balls were barely half empty, with new waves of genetic material being quickly produced and stored inside the gurgling orbs. He lifted himself up from the ground and moved behind Sally with a delight drawn on his muzzle. Their current size difference reached a pretty ridiculous stage as the cougar's torso was barely reaching above the panther's buttocks. And yet Reed groped her ass cheeks firmly, having his paws full with panther's large, firm body mass and pressing his throbbing, barbed tip against black feline's entrance. Digging his claws into that flesh for better aim, male stud shoved his cock way deep inside Sally, without a slightest sign of resistance. Her insides felt much more roomy than Freya's, and yet his dick was large enough to make panther moan loudly.

"Rrrrhhh! That's a good boy... Breed me..." she uttered, clawing the nearby rubbles and streets surface, panting loudly as each cougar's thrust was driving her insane. Her large rump was bouncing each time Reeden shoved his barbed, monster sized member deep inside her, digging his claws into Sally's body mass. His heavy balls were swaying behind, slapping loudly against the panther's inner thighs, sagging low as cougar's sheath was almost reaching the ground. Black female's pussy was extremely moist, giving Reed all the lubrication he needed to penetrate her deep, spreading muscled inner walls to the point that they were gripping around his cock in need of male's semen, milking him mercilessly. When he groped her tailbase with paw, pulling her ass closer to him for deeper penetration, Sally turned her head around, looking at the cougar with almost animalistic desire, biting her lower lip. "F- fuck... Just cum already...!"

And so he did! While still being sensitive from previous release, it didn't take long for a cougar male to give a muscled panther quite a load of his genetic material, shooting deeply into her womb, replacing her ABS with the belly of a pregnant female. Even if Sally was bigger than Reed, soon enough her insides couldn't contain the flood of male's cum, leaking outside her needy cunt. The sensation of being filled to the brim was too much for the panther as she just laid her muscular body on the ground, closing her eyes and panting heavily, massaging her inner lips with paw pads. An extra amount of male's creamy seed, mixed with Sally's juices drowned the city's streets like some kind of a weird flood, marking them with the scent of a pure need.

"Rrr... M- more..."
