It had been a long summer. The heat droned on and the humidity was making everyone quite miserable. However it was all but over. Parents were done taking their kids for back to school shopping and teachers were prepared for the return of their students. Tristan was not ready to go back to school but nor was any other kid for that matter. He was a 12 year old rabbit cub with dark brown fur spatted with different spots about him. Living together with his older brother and their parents on the outskirts of the burrow. They were but a kilometer or so from the school.

The morning came like clockwork. A rooster crowed off signaling an almost cliche start to the day. Tristan rolled out of bed and rubbed the encrusted sleep out of his eyes by grinding his fisted paws into his weary visage. A groggy yawn followed as Tristan tried to awaken from his slumber. A knock on the door and a gentle shout from his brother urged Tristan to make haste. It was the first day back to school after the break and he didn't want to be late. Tristan took a quick shower which only quickened his release from his stupefied state of slumber.

Tristan slipped back into his room to dress himself. Today he had chosen a modest wardrobe, a tan colored t-shirt with some jeans. As per usual Tristan wore his gym shoes with matching gray socks. Only because they were broken in and comfy on his large lapine feet. Grabbing his backpack, Tristan rushed downstairs to make a quick dash for breakfast. His brother had already planned a quick meal for him. The carrot and juice were set aside for him with a bag for his lunch. Tristan hurried to grab it before stuffing his faced muffling a quick "Goodbye" to his brother rushing outdoors to the school bus.

Luckily for the rabbit the bus had not yet arrived. Though only moments later the cheese colored wagon rolled around the corner, already half full with kids. The vehicle motioned to stop at the signage with a loud hiss. The glass doors hinged open allowing Tristan entry onto the transport. Tristan made his way inside before peering around for a suitable place to sit. It didn't take him long to spot a familiar face. A female tabby cat sat several rows behind the first, currently alone. Tristan made his way to the vacancy.

"Hiya, Margot." Tristan greeted the girl as he calmly sat alongside her.

"Oh hey, Tristan. How are you?" The feline smiled warmly at the rabbit boy.

Margot was a transfer student who had come recently from France to the States. The two had really hit it off last year after meeting in January. Margot was finding it hard to get along with the other kids as she had a strong accident that often rubbed people the wrong way. The whole stuck up French stereotype had followed her since she had arrived. To top it off Margot was but a frail girl despite her efforts to better herself. She was far from your average 12 year old girl. She is what most would consider a tomgirl.

Margot preferred wearing boyish clothes and the only thing overtly girlish about her was her budding bossom. Her hair was a bright orange in a tone that matched her fur. It was frizzy and kept rather carelessly over her head. She was rather small for her age, easily the shortest in class. However for what the feline lacked in size she made up in strength. One thing she enjoyed was weight training. One could often find the kitten in the gym attempting to power lift with her meager strength.

She could easily overpower Tristan despite being several centimeters smaller than him. The girl was quite the athlete. Though she was not muscle bound she did have a nice frame about her. Far better filled out than the boy who had naught but a fairly average build for his age.

"I'm good. Ready to back to school?" Margot inquired from the rabbit.

Tristan simply nodded softly not saying anything. The two set casually as Tristan looked back and forth between the girl and the window over her shoulder. He was dealing with a fit of nervousness and couldn't quite explain it, even to himself as his mind wandered too and from the feline.

"Something wrong, Tristan?" Margot noticed the boys discomfort.

Tristan still couldn't quite speak. It was as if the cat had caught him by the tongue, or so the idiom goes. Instead he went about shaking his head. Fortunately for him the bus had arrived at school and it allowed him to move away from the tabby. It wasn't as if he were afraid, it was just that she was making him feel very strange. The rabbit decided to confront the awkward feeling later. He didn't want to deal with the butterflies any longer.

School went by like normal. The two didn't share many classes except for physical education which was after lunch for the second years. Of course even in that setting they didn't see each other much as the sexes were separated by gender. Tristan had mischievously planned something in an effort to impress his little friend. He knew that the coach of the boys PE squad kept a stash of supplement in his duffel bag.

The small rabbit looked about the gym making sure no one was looking for him. Luckily the boys were occupied with a game of dodgeball and the coach was busy maintaining expulsions from the game. Tristan sneaked around near the bleachers where the coach normally kept his bag. Towards the end of the bottom row, he spotted it. The bag was a bright candy red and already conveniently open. The rabbit stashed his paw inside of it before rifling around for what he was looking for, a medicine bottle.

It didn't take much effort to find, a few seconds at most. Holding the prize in paw, Tristan made his dash out of the gym. Fortunately for him everyone else was playing in the center of the arena. He decided his little surprise couldn't wait and hurried to the girls side of the central hub. The girls coach was much more stern than the boys but allowed them free reign of the complex. Towards the back was the place where exercise machines were placed in no particular pattern around the floor.

The population was older than Tristan as this location was mostly secured for the upper school students. Margot didn't mind it much and was fixed in a corner lifting some bar bells on a cushioned table. Her meager strength was enough to lift the 5 kilo weights which she was doing repetitions on. Tristan calmly made his way over the the far side of the complex where his friend busied herself with weight training. Firmly grasping the vial in his paw with a smile. The boy approached his target with a sense of anxiety about him.

"Oh hey, Tristan. What're you doing over here?" The feline flipped her tail casually behind her.

"I got you a present..." Tristan approached the girl with a tremor in his grip.

Margot was unable to see what the boy clasped in his paw, looking over him curiously.

"You do but why? It's not like it's my birthday." Margot inquired ceasing her arm pumping action.

"I dunno...I thought you might like it since you enjoy lifting so much?" Tristan opened his paw revealing the neon orange vial.

"What is that?" Margot made the vial out simple enough but knew not what it contained.

Tristan approached the lifting station holding out the supplement to the feline. The cat took the container into her own hand before examining it. It was obvious enough what it was once she read the label which was clearly marked as to it's purpose.

"I figured maybe you might like some enhancement in your training." The rabbit stammered releasing the container.

"Is it safe?" Margot looked at the bottle examining the contents inside of the transparent plastic.

"I guess, it must be since coach had it." Tristan shrugged slightly, no longer stuttering on his own words.

Margot picked herself up from the lifting station heading over to the left side of the room where a watering fountain was placed. Selecting the smaller fountain on the right she fished out two capsules from the container into her paw. Tristan watched from behind in the distance. The feline downed the two pills into her mouth before swallowing them in one go. There was no taste to them and they were simple enough to ingest. She returned shortly after to the station.

"Want to arm wrestle?" Margot asked with a challenging tone.

Tristan know full well he would likely lose but decided to entertain the idea nonetheless offering a smile before sitting down on a nearby table extending out his arm onto the wooden table top. The feline plucked her tail behind before joining him at the station. She had set the weights aside so it was barren of equipment. She grinned at him with a tad bit of arrogance about her. She knew full well how this would end up. The two locked paws before looking into each others eyes with a gentle stare.

"Ready?" Tristan asked preparing himself for a willing defeat.

Margot engaged with those words using her superior strength to toy with the rabbit. Holding his paw she wrestled his strength against her own. For but only a moment she toyed with him, allowing a stalemate with the two of their hands held up full mast atop the wooden table. Her red eye's glinted at him. Tristan was clearly trying but unable to move her a stalwart state of limbo. With only a slight bit of effort she decided to weigh in, full strength into motion pinning down Tristans paw with a muffled thud.

"I win." She said with a chirping and happy voice.

"Yup! You did." Tristan picked up his paw to rub at it a bit, though not in pain.

Tristan looked over at the clock. Only several minutes were left before the bell would ring. He had to go back for dismissal from the class.

"I gotta go, Margot. Cya later alright?" Tristan gathered himself up from the table standing erect.

"Alrighty, Tristan thanks for the match." Margot positioned herself next to the taller rabbit before hugging him tightly.

The hug didn't last long, in fact it was rather short. But it made Tristan blush, slightly hesitant only to return a half hug on his own part. For a moment he experienced the hair on her head brush into his chin. Sure...it was unkept but she had always been below chin level for him. Now he more evenly saw the top of her head...and he couldn't explain why. The hug was broken and Tristan decided to make his way back. Briefly he looked back at her, nothing seemed to different about her, he supposed.

Tristan made his way back to the boys locker room. The boys had already retired and were changing back into their normal school outfits. It didn't seem that Tristan's absence was noticed and he used that to his advantage. Simply going about his business and joining in the unceremonious changing of the clothes. After the act was done they were dismissed and went about their day like normal. Tristan filed out and went about his normal boring day awaiting for the end like any other kid his age.

The rabbit eagerly welcomed lunch. His brother had packed him his favorite meal, a broiled vegetable sandwich with some carrot juice. Peering into his back the boy found a snack pack yogurt was stashed for his enjoyment. Once the bell rung Tristan hurried off to the lunch room. The first years were already in their seats dining away at various delicacies. Many kids were lined up waiting for the cafeteria food. Tristan skipped past the line looking to see if Margot had arrived yet.

The boy spotted the feline near the back, alone as per her usual routine. Knowing she could use the company, he made his way over to her. Tristan brushed over her casually with his paw, grazing her hair with his paw ruffling it a bit. A slight tweak in the wood could be heard as he did so.

"Hey, Tan." Margot tried out her newly created nick name for the boy.

"Tan?" Tristan asked curiously joining the girl on the bench sitting next to her.

"You know, like the chocolate brand?" Margot's hair brushed against Tristan's cheek as she turned her head.

"Oh that's cool! I've never had it before, is it good?" Tristan asked flinching from the girls hair rubbing against his left ear.

Margot nodded at the boy before returning her attention back to her food. She seemed quite famished and devoured the food quite readily.

"Hungry, huh?" Tristan noticed her increased appetite.

The feline didn't respond as she was much too engaged with her dining experience. Tristan searched through his things fetching out the small box of yogurt, gesturing it in front of her to gauge if she wanted the desert. The smaller girl smiled a bit before leaning over and planting a kiss on his cheek. This unexpected action made Tristan blush profusely. The chair beneath them creaking again ever so slightly as her lips touched him.

In a state of disbelief Tristan looked over, still unable to speak. Now eye level with the top of her head, it was becoming more obvious that something was going on. Even the girls clothing clung tightly against her body. Though it didn't seem to cause her any discomfort, her wardrobe was definitely tight on her body. It was as if she was getting...bigger.

"Hey, Margot, do you feel any different?" Tristan decided to confront the issue.

"No, why?" Margot continued to finish the rest of her meal.

"I dunno, you just look...bigger to me?" Tristan examined the feline once again.

"Bigger?Why do you think that?" Margot examined herself for a moment after finishing her treat.

"Oh...I guess my clothes have gotten a bit tight, huh? Maybe I'm having a growth spurt?" Margot suggested calmly brushing it off.

"Maybe? Stand up for a minute." Tristan requested doing the same motion.

As she did so, Tristan compared her to him. Though she was still shorter, it wasn't quite as much as it had been. It seemed too drastic too be realistic. She finally realized it too.

"I guess I am getting bigger, huh? Cool!" Margot sized herself up next to the rabbit seeming excited about the idea.

"Yeah...I guess. But I wonder why?" Tristan thought about the notion for a moment...he rather liked the idea of a larger Margot.

There wasn't much time to consider the question. Tristan had to rush eating his food. He had frittered too much time dilly dallying with his friend. Once the bell rung he stuffed his mouth with his sandwich before devouring it in a single gulp. Margot watched him half with disgust and half with disbelief.

"See you after school, Margot?" Tristan swallowed deeply to avoid talking with his mouth full.

"Sure, Tan." Margot smiled before walking away to her last class for the day.

Margot ruffled the boys hair before walking away calmly. The tight fitting clothing stretching along her form as she strode towards the exit. It was quite the site to behold from behind, one that Tristan had to stop himself from staring at after realizing it.

The rest of school went on like normal. Occasionally Tristans thoughts went to Margot but he composed himself all the same. He was quiet and reserved boy generally keeping to himself. He only found solace in his kitten friend. The last bell of the day finally rang. The threshold of kids flooded out of the exit doors, running towards their different destinations. Many hang about loitering. This was one day where Tristan had decided to do the same. After all he had promised Margot.

Tristans short tail flitted behind him as he awaited eagerly by a tree in the front of the school. It was warm out so the shade was a welcome addition to shield him from the sun. The boy positioned himself with one leg bent so that his right paw rested against the tree. Margot was seen towards the back of the crowd. The rabbit beckoned her over with a soft wave to coax her into the shade. The feline drifted over allowing her tail to coast behind her.

The lapine eased himself off the trunk standing up straight to greet her. The shade eased the fiery shade of her fur and hair making it a bit darker. Margot smiled at the boy making her way over to him. Pressing her nose against his, she leaned in for a light kiss on the rabbits lips. Tristan closed his eyes, his face taking on a more blood red fuse beneath his brown fur. Once it was broken the boy was in a state of bliss unable to act but for a moment.

When he finally opened his eyes, he was greeted by the cat, except she was now eye level with him. A smirk littered her face as she gazed into his eyes with an untapered sense of passion. It seemed she was quite taken by Tristan and he wasn't one to protest the idea. The boys stomach is a aflutter with what felt like butterflies and he couldn't quite shake the feeling from his person. He wanted to kiss her....again.

Tristan gave into his desire freeing both of his paws to embrace her in a tight hug. Once more he closed his eyes. Their lips met together, the sickly sweet feeling of romance filled his young body. With each passing second they locked together his chin had to arch just a tad further...almost feeling her creep up with every passing moment. A quick exploration of the tongue entered into Tristan's maw before their embrace finally broke. Tristan didn't want to let it end...even know it had to eventually.

Opening up his eyes Tristan had to look up to catch a glimpse of his feline friend. Margot was bigger now, definitely taller than the rabbit. The boy stood in awe as the cat seemingly loomed over him now. Even if it was just a bit...the difference was clear. Fantasizing for a moment about the possibilities that opened the girl backed away a little put off by the change of perspective.

"What's happening to me?" Margot asked finally confronting the issue.

"I dunno...but I think your growing!" Tristan said with an unexpected joy.

"I mean...yeah but why?" The feline examined herself.

By this point the cat's clothing barely hung on her. Her jean-shorts button had given way with her zipper down from the pressure. She leaned over sitting down, even her shoes were causing her pain. She took no time in forcing them off her feet. Even taking some time to rub her feetpaws which had been crowded inside the footwear for some time. Sighing in relief she set the pair aside looking quite happy to be rid of them.

"That feels....so much better." A smile returned to Margot's face

"I guess your in discomfort? Here let me help you..." Tristan made his way over to the cat

Tristan was genuinely a thoughtful boy and he especially cared for Margot. His brother had taught him how to massage, though he was no expert at it. He figured this was a prime time to test his skills. The boy positioned himself behind the cat before gearing his paws over her shoulders. Using his paws to thread into the tense muscles of the stressed girl before him. Little did he know that with each knead of his hands, the girl was steadily growing larger.

Margot let out a soft sigh. As the attention went on, her shirt finally gave way revealing the small set of breasts that were uncovered. Seconds later her pants too finally gave way, the seam near the zipper splitting and leaving her with a torn pair of pants and stretched out green boxers over her midsection and thighs. Tristans paws felt like they were on a gentle elevator rising up ever so slightly with each passing moment, finally letting his attention cease.

"Mmm...Why did you stop?That felt good." Margot murmured in a slightly deeper tenor.

Tristan had cautiously watched from his perch atop her shoulders, he was finally realizing just what made her grow. Even sitting down she seemed larger to him. Tristan wasn't sure if he should reveal the concept or not. He decided it could wait in order to maintain the closeness of the moment. He liked being near her no matter how big she was getting. The boy couldn't help but notice he was getting aroused from being allowed to comfort her in this way. He hoped she wouldn't discover it.

The cessation of action led to curiosity on Margot's part. Turning around her head she realized just what had caused the rabbit to stop. A small bulge was forming in his pants and her noticing it, only made the boy blush profusely in embarrassment.

"Hehe, enjoying youserlf, Tan?" The feline didn't mind his excitement all that much.

The girl tilted herself on her side so she could shift her body around. Almost encapsuling the smaller boy in her legs. Keeping him in between them with Tristan clearly in her focus, staring at him without a word for a moment.

Gently she reached forward and Tristan certainly didn't stop her. Her slightly larger palm flexed as she did so. Finally planting itself firmly on the rabbits crotch. A pleasant euphoric feeling filled the boy with a feeling had had not experienced before. Margot began gingerly toying with his crotch, as a feeling of anticipation bubbled up inside of the rabbit cub. As she did so her body continued to swell on the floor beneath her.

The calm gentle breeze of the wind carried against their fur. No one was left around them or they may have attracted attention. Margot continued to toy with the fly on the rabbits pants which she fiddled with til it met it's resting point. Tristan watched silently as his arousal was revealed to his friend. Working her way into his pants she freed the jean shorts entirely before they finally slouched to his feet.

The feline's body continue to fill out with each passing moment, the longer she indulged in the boy. Touching his crotch brought a sharp spike, almost an electric pulse tingling sensation coursing through her body. She could feel herself getting stronger...bigger. The more she experienced it...the more she wanted it. Her body was into both the sexual element as well as the power element.

Gently she began pawing the boy off. Her larger paw easily handled his smaller member, making him feel quite self-conscious about the whole ordeal. Pumping her hand rather meagerly at first she approached the task with a rather ginger composure. Before long....even sitting down her frame matched his even standing up. His little cock stood up quite readily and eagerly against the touch of their newfound affection.

Peeling down the briefs revealed his aching hard erection. He didn't even seem bothered by her growth at this point. Both of them had become aware of her sudden spurt. In truth she had just now realized how the notion worked. Indulging in her little friend only seemed to catalyze her size...To that extent she was stretching this out as long as possible, simply teasing the bunny with her fingers. Still her frame steadily crept upward...and she was getting quite the power trip.

Now dwarfing him even sitting down Margot continued to work on the boys genitals. His balls ached for attention and he wanted nothing more than to finish. Rolling his eyes back in his head, she allowed her palm to flex continuing to pump his little cock milking a little pre-cum from his tip. He was young, his limit would likely not be far behind. The feline reached in, easily reaching him with her increased scope.

Relaxing her palm left the boy cub wanting more. She was eager to give in, bowing over and bend her back relaxing her longer tongue over his crotch. Lapping along the length slowly caused the boy to arch forward thrusting his hips into her action. Diving in she allowed herself to engulf his member entirely resulting in a gaping sigh from the boys mouth. Tristan couldn't help but roll his eyes back in his head, he was close and wouldn't last long at this rate.

The rabbit gasped as he edged closer and closer to orgasm. A quick twitch and throb of his shaft before strings of fluid shot out into the eager girls mouth. Margot had not experienced the taste before the warm fluid met her taste buds. It was salty and somewhat bitter but not all to distasteful. Swallowing the stuff she leaned backward finally releasing the boy from her clutches. Her body was quite sore at this point.

Margot's muscles ached and her joints creaked. None of her clothing fit anymore and she was all but naked in front of her. Though modesty could easily be forgone considering their actions.

"Wow....that was amazing..." The rabbit stammered trying to catch his breath.

"Hehe...I'm glad you liked it, Tan." The cat's voice echoed in a booming manner.

"Your so big now..." Tristan remarked finally snapping out of his stupor

Looking over herself would have proven that but she knew well enough that this was the case.

"Yeah, it's pretty cool. Huh?" The feline considered how much could do now.

Margot engineered herself up having to duck under the tree branches in order to fit herself. Offering her paw down, she lured the boy onto her paw. He was easily small enough for her to manipulate, though she certainty didn't want to harm or scare him.

The feline fastened him on her shoulder before finally making her way into the open. Surely such a large cat would quickly catch attention. Though the idea of being her play thing didn't seem adverse to Tristan. Calmly he sat himself atop her shoulder as she strode about the city. It had been a long day and the sun was beginning to set. Was this just the beginning of their relationship and adventure? Only time would tell.
