Kayla lay awake in her bed, looking up at the glow-in-the-dark stars that were stuck all over her ceiling. The 10-year-old rabbit cub was trying her hardest to keep her tired eyes open as it got later and later. She rolled her head to the side, reading the glowing numbers on the clock next to her bed: 11:09, way past her 9 o’clock bedtime. But despite how sleepy she was getting, Kayla was determined to stay up long enough for her older brother to fall asleep. She had stopped hearing noises coming from his room about 15 minutes ago

“I wonder if he’s asleep yet,” she thought to herself. The tired little cub could feel her eyes droop and close and quickly opened them back up, shaking her head to wake herself back up. Her floppy, pink and white ears slapping softly against her pillow as she did. Kayla sat up, deciding that it would be easier to stay awake if she wasn’t laying down. She glanced back over at the clock.

11:10

“Oh my god! It feels like it had been five minutes!”

Kayla was getting impatient, driven in part by her excitement. It all started last week when her and her friend snuck a peek at her older brother’s cock while he was napping and Kayla proceeded to paw him off while he was tied up, her friend watching the whole thing. This of course escalated, as their rivalries typically did, with Kieran seeking his revenge, inviting his friend over and having their own fun at Kayla’s expense; they stripped her down and Kieran ate her out until she had her very first orgasm. They were going to stop there, but a joke that got out of hand led to both of them taking turns fucking her.

Now, the cycle of vengeance was repeating, with Kayla determined to get Kieran back by doing the same thing to him that he had done to her. She threw off the covers and hopped down out of her bed. She quietly left her room, making sure to close the door behind her so it’d look like she was still in there asleep, just in case her parents checked. Her small paw closed around the doorknob to her big brother’s room and very carefully rotated it. Without a sound, she pushed open his door and shut it softly closed after entering.

Kieran’s room was dark, but there was enough of a glow from his clock-radio, and her eyes were already adjusted to the dark enough, that Kayla could make out all the shapes. Silently, she stalked over to the end of his full-size bed. The devious little rabbit cub lifted up the covers from his feet and crawled underneath them. Luckily, Kieran’s legs were spread out a bit and Kayla was small enough that she was able to crawl up between his legs without disturbing him. When she reached her goal, Kayla paused for a moment to double check that her older brother was still asleep. Gentle snoring confirmed as much and she put the next phase of her plan into action.

Despite the darkness, Kayla was still able to make out some sparse details under the covers, though admittedly not much. She gently felt along his hips until she located the waistband of his boxers. Gripping them in her fingers, she gingerly pulled them down, until they were just below his member. His soft, uncut cock lay resting between his legs, sleeping as peacefully as its owner. Kayla wrapped her tiny paw around the shaft and lifted it, getting straight to work. She stuck out her tongue and licked along the bottom of it, from the very base to the tip.

[i]That[/i] woke up Kieran’s sleeping dragon, which quickly became stiff in Kayla’s grasp. However, the teenage owner appeared to still be sound asleep; in fact, the only thing that seemed to be stirring was his loins. Kayla gave another lick, following the same path she had before. This time, Kieran let out a soft moan in his sleep. This only spurred Kayla on and she quickly gave another wet lick along her brother’s shaft.

Kieran’s eyes shot open and he fumbled with his bedside lamp, switching it on quickly and then lifting up his covers. Staring up at him with squinting eyes was his little sister, her paw still wrapped around his hard cock, her tongue out, having been caught just as she was about to give another lick. She was all scrunched up, underneath the covers, her legs tucked neatly under her.

“Kayla!?” Kieran whispered loudly. “What the hell are you doing!?”

“Getting you back!” she replied in the same yelling-whisper. With her semi-shut eyes still locked with his in a stern expression, she gave another lick from bottom to top. Kieran’s penis throbbed, pushing a drop of clear precome out of his tip. Kayla liked up the salty fluid before starting back from the bottom, giving him another full lick. The teenage rabbit gritted his teeth. He hated to admit it, but it felt really good. If this is what his “punishment” was going to be, then perhaps that wasn’t so bad. Still, perhaps because they were siblings, or perhaps because of their rivalry, he felt like he at least had to pretend not to enjoy it.

“Wait, Kayla, wait,” Kieran insisted. She stopped licking, but didn’t let go of his cock. She wasn’t going to let him off that easily.

“What?”

“I have an idea. A game we could play,” he offered.

That got her attention. Ever since she could remember, her and her older brother had been super competitive, trying to beat each other out at everything from board games to video games to even simple foot races; anything they could turn into a competition, they did. Being older, Kieran often came out on top, but Kayla was relentless in the pursuit of victory and it had netted her some wins over the years.

One of her eyebrows raised up and she gave him a skeptical look. He was just trying to get out of his punishment, she was sure of it. “What kind of game?” she asked hesitantly. Kayla was definitely more than a little intrigued about this opportunity to compete with her big brother. She figured it made sense that he knew something she didn’t about this kind of stuff, since he was six years older than her.

“Well, do you know what ‘sixty-nine’ is?”

“Like, the number?” Kayla asked innocently.

“No. Not the number.”

Kayla shook her head.

“What about a blowjob?”

She blushed, nodding this time. Admittedly though, she only had a rough understanding of what the term meant. It wasn’t as though she had any experience or had ever even seen one. “Blowjob” was just a funny word that her and her friends would giggle about and had something to do with a boy’s wiener in a girl’s mouth.

“Well, sixty-nine is a...position...where the boy eats out – licks – the girl and she gives him a blowjob at the same time.”

Kayla listened attentively, her eyes fully-open now that they had adjusted to the light. She tilted her head to the side some. “How?” She was trying to figure out exactly how that would work or even be physically possible.

“You wanna find out?” Kieran proposed, a tiny hint of eagerness in his voice. There was obviously more to his question than a simple explanation.

His little sister only had to think about it for another couple seconds. “Yeah.”

“Alright, get out of my bed and come over here.” He gestured to the side of his bed, next to his nightstand.

Kayla scooted back down until she emerged from the bottom of Kieran’s bed. She quickly made her way over to where her brother had motioned to and stood there at attention.

“Alright, now...[i]get naked[/i].”

The young bunny girl blushed, her eyes widening a little in surprise at her older brother’s rather blunt request.

“L-like all the way?” she asked nervously.

“Mhmm.” Kieran nodded. “Like you’re going to take a shower.”

“O-okay,” Kayla replied shyly. She did as her older brother instructed and began stripping down to her birthday suit. First, she pulled her plain white tank-top up and over her head, dropping it to the floor once it was off. Next to go were her black gym shorts and underwear; the tank-top and shorts combo was a favorite lounging around outfit of hers – in part because it wasn’t super girly. Kayla was a bit of a tomboy and was always dressing a bit more like a boy than a girl, at least when she could get away with it.

She pulled down her shorts and underwear together, stepping out of them once they were around her ankles. Kieran caught a glimpse of her panties, which were still inside of her shorts – just enough to notice that they were white on the inside. However, his attention quickly focused upwards, as his little sister was now standing butt-naked in his room, right next to his bed. 

It was the first time he had seen her complete nude in a very, very long time – not since she was a tot, running around without a diaper. Sure, him and his friend had gotten her most of the way there last week, but there was just something different about the fact that now she was wearing [i]absolutely nothing[/i]. 

Not only that, but she had undressed [i]herself[/i] this time too. For some reason, that made it even more exciting. Perhaps because it was like he was getting a peek into part of his little sister’s normally-private bathing routine; the manner in which she removed her own clothes and what she looked like without – details that normally only she and the bathroom mirror would be privy to. Now, anytime he would hear their shower turning on, he’d have a mental picture of what was going on behind the closed door.

His eyes looked her small body up and down: her cheeks were rosy and flushed; small, pink nipples stood out against white fur on her flat chest; her abs were flat and toned from how active and athletic she was; her arms, hips, and legs were all quite slender, having not yet grown into the shapely curves of a woman. In fact, her whole physique was rather androgynous – like that of most cubs. There were only two distinguishing physical features setting her apart from the boys: her more rounded face and, of course, her privates.

The small slit tucked away between her legs was the main thing Kieran found his eyes being drawn to; it was completely exposed – bare of even a single strand of the dark, coarse pubic hair that Kieran himself had. He couldn’t get over how cute and innocent it looked, just barely peeking out, concealing her more intimate details. It was almost hypnotizing to look at, trying to imagine what lay between those soft, puffy lips.

Kayla noticed that Kieran had been staring just a bit too long for her comfort. She placed a paw over her crotch, covering herself and blocking her older brother’s lustful view. “What’s the game?” she finally asked, trying to return his attention to the fact that he was supposed to be teaching her something. He shook his head a little, coming out of the stupor that admiring his little sister’s cub-anatomy had brought upon him.

“Right...well, so we sixty-nine and see who can make the other cum first,” he explained. 

Kayla still had a slightly confused look on her face. 

“Cumming is when you have an orgasm,” Kieran supplied.

The young bunny cub still didn’t seem to be following. 

“An orgasm is what happens when you feel really, really good. Remember when I was licking you down there and you felt all tingly and your legs shook?”

Kayla nodded shyly, blushing a bit more as her brother recounted the experience.

“And didn’t that feel [i]really[/i] good?”

Another shy nod.

“Yeah, that was because you had an orgasm.”

“Like when you shot the white goop out of your dick?” she pointedly asked, trying to turn the attention away from herself.

Kieran blushed slightly. “Y-yeah...that’s semen and it comes out when a guy orgasms.”

Kayla smiled, proud of herself for remembering and getting that right.

“So you wanna play or not?” Kieran asked again, knowing full well that even if he lost, he won.

His naive little sister nodded enthusiastically.

“Okay, cool. Climb on top of me, but with your head towards the foot of the bed and your butt up towards my face.”

Kayla giggled at the combination of words, but started to climb up onto her brother’s bed anyway. She climbed on top of him, straddling him and placing her feet on either side of his head. “Like this?” Kayla asked innocently, scooting down a little so that her knees were down near his chest.

“Y-yeah.”

Kieran’s response was a bit distracted as his little sister positioned her privates right in front of his face. He honestly wondered if she had any idea just how revealing the position really was; he could see everything! The full length of her slit was now presented to him. Her pink clitoral hood, which she hadn’t yet fully grown into, peeked out from between her labia. Towards her entrance, her lips were slightly parted, teasing at the hole that lay hidden within. And above that, her tightly puckered tailhole was on full display, with her cheeks spread and her fluffy white tail lifted as she leaned forward.

“Hey Kieran?” Kayla peeped, gently taking her brother’s erection into her paw. “How do I give a blowjob?”

It was perhaps the hottest question his little sister had ever asked him, especially since it was while she was holding [i]his[/i] cock.

“Ah, well...pull down on the shaft to expose the tip...then, basically, you put it in your mouth and suck on it and lick it and stuff,” Kieran explained, never having really thought about the specific mechanics of it before. “And kinda move your head up and down, I guess? And try to not touch it with your teeth...And don’t bite it!”

“’Kay.”

Kayla lowered her head down and tugged with her paw, pulling his foreskin down and revealing the round, pink head of his cock. Kieran couldn’t see it, but could certainly feel it as his little sister’s lips closed around his penis. It was warm inside of her mouth and he could already feel her wet tongue pressing against his tip. Kieran let out a small moan, suddenly surprised by just how good it felt. Kayla was evidently determined to get right to it and win this game.

Kieran didn’t waste any time either; he spread his sister’s pussy lips apart with his thumbs, revealing her bright pink flesh inside. He craned his neck and brought his mouth to her clit, pressing his lips firmly around it, creating a seal. Immediately, he started to suck and pushed his tongue forward, licking the little nub over and over. Kayla couldn’t help but let out a small whine of her own as her pleasure button was suddenly stimulated. Her teeth grazed Kieran’s shaft as she lost concentration; Kieran winced, but didn’t find it nearly as bad as he thought he would.

The little bunny cub started to suck, causing her tongue to press firmly against the top of her brother’s cock and forcing his glans against the fleshy palette of the roof of her mouth. She started to bob her head up and down, taking a fair amount of his length into her mouth, all the while sucking on him. Occasionally, the airtight seal her lips were forming around his cock would break, and a sucking sound would escape, echoing in Kieran’s bedroom.

Not to be outdone, Kieran redoubled his efforts, sucking more and flicking the tip of his tongue rapidly against his little sister’s eager nub. She whined pleasurably again, her mouth vibrating around his cock. Kieran noted just how stiff her tiny clit felt against his tongue; he pulled his face back, examining her privates. Her bright pink clitoris was now fully erect, peeking out from underneath its protective hood, demanding more of the stimulation it had been receiving. Her pussy lips had blossomed open, the two ridges of her inner labia were a bit swollen and slightly darker, and even her scent had changed – becoming more of an arousing feminine musk. 

Her 10-year-old cub-body was in a state of full and complete arousal.

Kieran excitedly dove back in, knowing that she must be getting close if she was this turned on. He pressed his tongue firmly against her clit and started to move it up and down, sliding it flatly in her slit. Kayla let out another moan, her concentration breaking as she lifted her head up, freeing Kieran from her mouth. Her breathing became erratic and her eyes closed as her older brother greedily ate her out. She pressed her hips backwards against Kieran’s face, wanting even more; she had completely forgotten about the game at this point. Now all that mattered was the nice tingling feeling coming from between her legs.

There was no way Kayla was going to win at this point; Kieran had already pushed her past the point of no return. Now it was just a matter of time. He didn’t let up, keeping a consistent pace and pressure against her clitoris with his tongue. Suddenly, Kayla’s whole body seemed to tense up. She clenched her teeth and whined pleasurably. Her right leg lifted up off the bed and started to rapidly kick, completely against Kayla’s will as her orgasm exploded. Her foot thumped repeatedly against Kieran’s headboard, knocking it into the wall over and over.

Kieran quickly grabbed Kayla’s ankle, not wanting the racket his little sister was making to wake up the whole house. But even with his strong pitcher’s arm, her uncommanded kicks were powerful and hard to restrain. Her whole body spasmed as different muscles contracted and relaxed, trying to dissipate the intense pleasure she was experiencing. Kayla whined more and Kieran grinned as he watched his little sister ride out her powerful climax. 

He had won.

Kayla’s kicking finally died down and Kieran let go of her ankle as she relaxed. She was panting heavily, still coming down from her high. She laid down on top of her brother, resting her head on his thigh.

It was then that Kieran heard the door to his parents’ bedroom open. His heart started to race and he quickly shut off his lamp and threw the covers back over himself and his sister. Footsteps approached from down the hallway. “Kayla! I think mom’s coming! STAY QUIET!” he urgently whispered. He pushed her bare feet down, shoving them underneath the covers right as his bedroom door opened.

“Kieran? Did you hear that thumping sound?” his mom asked through the darkness.

“Y-yeah,” he feigned a tired, just-woken-up voice. “What was that? Like a tree branch hitting the house or something?”

His mother yawned, “I’m not sure. I’m gonna go check on Kayla…”

“No!” Kieran called out as she started to turn to leave his room. His mother turned back around confused. “No sense waking her up and scaring her if it’s nothing, you know? I’m sure she’d be running out crying if she had heard it.”

Kayla was listening from below the covers. “Oh no! He did not just call me a cry-baby!” she thought angrily to herself. Kieran may have won the battle...but there was still the war.

“Yeah, I suppose you’re right,” their mother replied, slightly confused but too weary to really argue it. She spotted a shadowy pile of clothes next to Kieran’s nightstand. “Kieran, what have I told you about not putting your clothes in the laundry basket!?” She was completely unaware that they were actually Kayla’s clothes and that her daughter was currently completely naked, underneath her son’s covers. 

Kieran looked over, seeing what she was referencing. His heart skipped a beat as he remembered that that was where Kayla had gotten undressed.

“S-sorry mom. I’ll take care of it in the-”

But before he could finish the sentence, Kayla’s warm, wet mouth closed around his cock. The rest of his response sounded awkward as his voice jumped and creaked at the sudden surprise.

“- MORning!”

There was a slight pause before his mother finally asked, “Are you feeling alright?”

Kayla had started to bob her head up and down, running her tongue along her brother’s shaft. She closed her lips tightly and started to suck. Kieran did his best to sound normal and calm, despite the sudden wave of intense pleasure as his little sister resumed sucking him off.

“Y-yeah. I t-think my voice just cracked,” he lied, trying to think of an excuse. “But I am pretty tried. G’night mom!” he tried to urge her out of the room, since Kayla was evidently dead-set on giving him head under the covers, just several feet away from their mother.

“Okay...goodnight...”

The cubs’ mother left the room, pulling the door closed behind her. Kieran listened to her footsteps retreat down the hall and eventually disappear into the master bedroom. As soon as he had heard their door close, Kieran flicked on the light and threw the covers off of himself and Kayla.

“Kayla! What the hell are you doing!? What if mom had found out!?”

But Kayla wasn’t listening. She just kept sucking, dragging her tongue up and down Kieran’s cock. He laid back, deciding if she wasn’t going to stop, he might as well enjoy it. 

Kieran reached up, spreading Kayla apart with his thumbs as she continued to suck on him. He examined her tight hole, which was glistening with moisture.

“Wow...,” he thought to himself. “She’s really wet...Even though she’s only in fifth-grade, she already wants a cock inside of her.” Kieran spread her entrance wider, peering into her fleshy, pink love-tunnel. He continued silently narrating to himself. “The whole point of this hole...Kayla’s vagina…is to take a penis inside of it...and make it cum. I can’t believe my cock fit in here – it looks so small.”

Kieran’s perverted thoughts as he examined his little sister’s private parts, combined with the head she was giving him, was quickly pushing him to the edge. Without even realizing he was doing it, he started to thrust his hips ever so slightly. Kayla was determined; she was not giving up. 

Her head bobbed up and down and the whole length of Kieran’s cock was slick with her saliva. Her teeth would occasionally graze him, but surprisingly, he didn’t mind it much anymore. In fact, it was almost like a reminder of how innocent and inexperienced she was at this; a reminder of the fact that she was still just a cub – of course she wasn’t giving head like a pro. 

The thought pushed him over the edge.

“K-Kayla,” Kieran moaned. “I’m gonna-” He closed his eyes, laying his head back on his pillow. His hips lifted slightly. Warm cum erupted from the end of his cock as he started to ejaculate inside Kayla’s mouth. Surprised by the sudden explosion of fluid, Kayla stopped moving, but kept her lips sealed around her brother’s shaft. Several more bursts of her older brother’s thick semen fired against the roof of her mouth as his cock pulsed.

Once he had finished, Kayla pulled her mouth off of his penis, keeping her lips together. She made a panicked, “Mmm! Mmmm mmm!?” trying to communicate without actually opening her mouth. She quickly hopped off of Kieran’s bed, pointing to her closed mouth. Her eyes were wide and her cheeks were slightly puffed out.

“Oh! Right!” Kieran realized his little sister’s dilemma and hopped up off his bed. “I’ll get you something in a second so you can spit it out. But first, open your mouth and show me.”

Kayla made a face, but did as he asked. Looking up at her brother with pleading eyes, wishing he’d hurry up, the young bunny cub opened her mouth wide. Kieran peered inside; his cloudy, white load was pooled in the bottom of her mouth. He watched as his seed slid over her tongue as she inadvertently moved around.

“That’s so hot...” Kieran said lustfully, his words trailing off.

Kayla closed her mouth back up and punched him. “Mmm mm mmmmm!”

“Alright! Alright! Hold on!”

Kieran started looking around his room for the roll of toilet paper he typically kept around for...reasons. He pulled out one desk drawer, then the other, but couldn’t seem to find it. His eyes fell to the wastebasket next to his desk; inside was the spent toilet paper roll.

“Oh right, shit...I used it all up,” he said aloud. “I’ll go get you some from the bathroom.” He started making his way to his bedroom door, then remembered he was naked. He doubled back, spinning around, looking around on the floor for his boxers. Out of the corner of his eye he noticed Kayla grimace.

“What?” he asked, looking over at her.

To his surprise, she responded normally. “I swallowed it.”

Kieran’s eyes opened wide. “You [i]swallowed[/i] it!?”

Kayla nodded reluctantly. “You were taking too long and I just sorta…”

“Show me,” he demanded once more.

She rolled her eyes again but opened her mouth regardless and let Kieran look inside.

Empty. 

Not even a drop of the cum that had been flooding it moments ago. The teenage bunny looked down at his little sister’s bare abdomen. He thought about the fact that, somewhere, behind that adorable belly button of hers, his full load was now sitting inside her stomach. Kayla closed her mouth and made a face.

“That was gross.”

“Yeah, well, I still won,” Kieran retorted.

“Yeah...well...I still made you shoot out the white stuff!” Kayla fired back, sticking out her tongue, trying to recover some ground in their made-up competition.

“That you did,” Kieran replied with a smile before tussling his little sister’s hair. She scrunched up her face in an annoyed expression and shook her head free from his paw. When she tried to look mad it somehow just made her look even cuter.

Kieran picked up his boxers and used them to wipe himself up. He looked down at them and shrugged before putting them back on. He climbed back into bed and watched as Kayla got dressed. She plucked her underwear out of her shorts and pulled them on. Getting his first glimpse at the outside of her panties, Kieran noticed they were covered in tiny, little green, pink, yellow and blue butterflies.

“Cute underwear,” Kieran remarked.

“Shut-up,” Kayla shot back without even a second thought, she snatched up her shorts and hurriedly  pulled them on to try to cover up her panties.

“No, I mean it. I think they’re cute. I like it when you wear cute things.”

Kayla just glared at him skeptically. She wasn’t sure if he was teasing her or what, but she figured he had to be making fun of her in some way. She picked up her tank topped and pulled it back over her head. 

“G’night,” she said with a little bit of an attitude, marching off towards the door.

“Hey, don’t be a sore loser,” Kieran called out as she reached for the handle.

Kayla steeled her expression and turned to face her brother. “...We’re gonna have a rematch sometime!” She held out her paw and gestured to herself. “And [i]I’m[/i] gonna win!”

Kieran just smirked. “Okay...” 

And with that Kayla left his room and went back into her own.

------------------

The next morning Kieran was pleased to find himself waking up naturally, rather than to the blare of his alarm clock like on the weekdays. He had expected to see the morning sun blasting in through his window, but gray, overcast skies made it look dreary outside. The teenage bunny stretched, lifting his arms above his head as he lay there in bed. His fist bumped into his headboard, lightly knocking it against the wall. The sound instantly recalled the auditory memory of Kayla’s foot thumping against it relentlessly, making the very same sound – but louder – just last night.

Thinking of the devil… The sound of feet, zooming up the stairs, at a speed which could only mean that it was Kayla, indicated to Kieran that his little sister was already awake. He heard her go into her room and close the door, only to reopen it moments later and zoom back downstairs. Kieran rolled his eyes and threw off the covers. “Guess it’s time I got up,” he remarked to himself, looking over at his clock with a yawn.

Kieran pulled off his boxers and grabbed a new pair out of his dresser. He slipped them on and picked a random shirt from his closet and pulled it over his head before finally sitting on the edge of his bed and pulling on yesterday’s pants. He did a quick sniff check to see if he needed a shower or anything and shrugged. 

“Meh.”

The sixteen-year-old exited his room and went downstairs, and, as he expected, everyone else was already awake. Sitting around the breakfast table were his parents, both still in their bathrobes and nursing warm mugs of coffee. And of course there was Kayla, who was already dressed up in her full volleyball uniform – knee pads and all. She was shoveling cereal into her mouth and swinging her legs, kicking them as she sat in the chair, her bare feet just barely not touching the carpet.

“Oh, good morning!” the cubs’ mother greeted her son warmly as she saw him approach. “I’m glad you’re awake – I was just about to come get you.”

Kieran looked confused. “Come get me? What for?”

His mother took another sip of her coffee. “Mhmm. I need you to take Kayla to her volleyball game today, okay?”

He tossed his head back in the dramatic manner that teenagers are so accustomed to doing.

“Uggghhh,” he sighed before looking at his mom again. “Do I have to?”

“Yes,” his mother affirmed. “Your father and I are having lunch with the Hendersons, so nobody else can take her.”

“Can’t somebody on her team do it?” he whined, finally plopping down in a chair at the table.

His mother shook her head, starting to get annoyed with his attitude. She looked at him seriously, letting him know that this was non-negotiable.

“Fiiiiine.” 

Kieran finally accepted defeat. Hopefully it wouldn’t take all day. “Oh! But I get to take the Porsche!” He had figured it was a long shot, but, one that he had to take. His father had yet to let him drive the fancy sports car even once.

Kieran’s father chuckled softly into his coffee mug, not even looking up from his paper. “Ha. Yeah right. And we’re having lunch on the [i]moon[/i].” 

“The minivan?” Kieran asked dejectedly, already knowing the answer. His father gave a single, stern nod. 

Kieran hated driving the family minivan; it was big and bulky and probably the least cool car on the planet. He looked over at Kayla who just looked back at him, taking a break from her cereal to stick her tongue out at him before she continued eating.

“Brat,” he whispered, quiet enough so that only she could hear it.

Kieran waited for his little sister to finish breakfast before they both gathered up their things and piled into the ugly, green van. He turned the key, cranking the engine which eventually sputtered to life. 

“Piece of crap.”

Kayla giggled and echoed her older brother’s sentiment. “Yeah! Piece a’ crap!”

The two smiled at each other, sharing a little sibling bonding moment at the expense of the family car. Despite all their bickering and fighting, the truth was Kayla and Kieran were pretty close – even if neither of them would actually admit it. 

Kieran looked out the window longingly at the Porsche and sighed. The two vehicles were complete polar opposites.

Kieran reached up and adjusted the mirror before pulling down the gear shift into reverse. He backed out of the driveway and they were on their way to Kayla’s game in the next town over.

The drive was uneventful and boring. When they finally arrived at the field house and parked, the two bunny siblings hopped out and headed inside. The sky was still dark and dreary and it was just starting to spit rain. Once they were inside, Kayla took off and ran over to her friends that were standing around on the court. Kieran took a seat at the back of the court, next to the parents of the other cubs.

A middle-aged lion sat down next to Kieran as more cubs and their parents filtered in.

“Which one’s yours?” the lion asked in a gruff voice, leaning in towards Kieran.

“Number 7 – well...she’s my little sister,” Kieran answered.

“Ah, Kayla, shoulda guessed. Family resemblance and all.” 

The lion coughed awkwardly, hoping he hadn’t offended. It was clear that he must have known Kayla from previous games. 

“Mine’s number 3, Savannah.” He nodded proudly towards his daughter. The young lioness was over with her teammates, crouched down retying her shoe. A twenty-something year old gazelle, whom Kieran assumed was their coach, came over and spoke to the girls. Shortly after that, the cubs spread out on the court to practice bumping and setting the ball back and forth to each other. 

There were cubs of all kinds there: lion, snow leopard, skunk, fox, canine, feline, panda, mouse, and of course rabbit; it was quite the diverse group. The coach, who was now assuming the role of referee, gave a short, sharp blow of her whistle, indicating the game was about to start. Some of the girls vacated the court while others got into their assigned positions. Kieran watched as they spread out, facing the net, away from where he and the other families were seated.

The ref lifted the whistle to her lips and the girls all got into their ready positions. Kieran couldn’t help but feel a little flushed as all the girls crouched down slightly and stuck their butts out, holding their arms out in front of them. All manner of tails lifted into the air as they prepared to start. But, before he could really take a moment to appreciate the sight, the referee blew her whistle and the game began.

A wolf on Kayla’s team, number 19, was serving. She tossed the ball up in the air and hit it over the net hard. As soon as the ball was over the net, the court became a frantic mess of cubs moving about as they all tried to get their chance to hit the ball back and forth. Sneakers squeaked on the wooden floor and tiny, feminine voices called out as they battled against the other team. Ultimately, the ball came down inside Kayla’s team’s court. Kayla threw her arms in a “shucks” motion but then patted the young skunk on the back that had missed the ball. 

This time, it was a fox on the other team serving. The girls all got into the ready position once more. Kieran couldn’t keep himself from leering at the fifth-graders; there was no fighting his teenage hormones. After all, a female lifting her tail and sticking out her hindquarters was pretty much the universal signal for willingness to mate for mammals; it was like all the girls were presenting to him all at once.

If there was ever a time that Kieran had wanted x-ray vision, it was this moment now. His eyes darted from one tight butt to another, appreciating the fact that the skin-tight spandex shorts left very little to the imagination. The shorts gave a perfect impression of each of the girl’s small cheeks. When his eyes landed on Kayla’s backside, he noticed something else: her shorts were actually tight enough that he could make out the pantyline of her underwear through the spandex fabric.

The fox girl served and the court, again, returned to being a chaotic mess, shaking Kieran from his hypnosis. However, the play was rather short and the other team had ended up dropping the ball, quite literally. The girls all got back into their ready positions; this was quickly becoming Kieran’s favorite part of volleyball. “How come I’ve never come to one of her games before!?” he wondered to himself.

Kieran took the opportunity to see if he could notice the outline of any of the other girls’ underwear while they waited for play to start. Now that he knew what he was looking for, he was actually able to make out the faint lines on the backsides of nearly all of the cubs. The one exception was the lioness cub of the man sitting next to Kieran. The teenage rabbit blushed. “Is she...going commando? Or, maybe wearing a thong?” he pondered quietly to himself. Either way it was hot.

He peered closer until at last he could make out the outline of two small humps between her legs. 

Kieran swallowed. “That’s...her [i]pussy[/i]! She’s not wearing [i]anything[/i] underneath her shorts!”

Just then, the lion dad next to Kieran nudged him with his elbow. Kieran just about jumped out of his skin. “Yaah!”

“Haha, jumpy, aren’t ya?” the lion laughed. He then lowered his voice and leaned over. “I was just trying to point out…” He nodded towards one of the moms on the other side of the court who was wearing a fairly low cut blouse. Her ample bosom was barely contained by the shirt – it honestly seemed like it was hardly the appropriate thing to wear to a cub volleyball game.

Kieran smiled, relieved that [i]that[/i] was the reason the lion had nudged him. He gave a sly guy-smirk and nod and the lion gave one back before they went back to watching the game. 

“Whew, I’m going to have to be more careful. I was sure he was going to tear my head off for leering at his daughter,” Kieran thought to himself nervously. “[i]Oh sorry sir, I was just imagining your cub naked[/i],” Kieran mockingly chastised himself in his mind as the ball was served and put into play.

As the game went on, Kieran was playing his own mental game of fantasy as he tried to imagine what things would have looked like if the cubs weren’t wearing shorts at all. What kind of underwear were they wearing? Were they plain and functional? Cute and girly? Or maybe they weren’t wearing anything, like the lioness?

Then, as if through some kind of perverted divine intervention, one of the girls on Kayla’s team dove for the ball. As she did, her paw snagged the shorts of the young skunk, pulling them down past her knees. The crowd gasped and the skunk girl let out an “Eep!” before ducking down and trying to cover herself up. But everyone had already gotten a flash of her cute underwear: white with little pink hearts.

The skunk cub quickly pulled up her shorts and ran out of the gym, crying. Kieran felt his heart sink a little bit; while it [i]had[/i] satisfied his curiosity (at least about one of the cubs), he didn’t like that it came at such an embarrassing cost.

“Poor girl,” the lion remarked from next to Kieran. “Getting her undies shown to everyone like that.”

“Y-yeah,” Kieran acknowledged.

“At least they didn’t get pulled down too!” the lion concluded.

Kieran didn’t respond. He only swallowed as his mind tried to fill in the mental image.

A couple of the girls on Kayla’s team had run after the young skunk. After a few moments, they all reentered the gym, their arms around their friend who was still rubbing her eyes. The black and white skunk cub went over to what Kieran could only presume were her parents, who gave her a big hug. She sat down with them and the crowd and players did their best to pretend that the incident never happened – figuring that the best way to minimize damage was to get back to the game as normal.

The rest of the game was fairly uneventful. Kieran found himself becoming increasingly aroused the more he watched. There was one particular play where Kayla jumped up to spike the ball, her striped blue jersey lifting momentarily as she did, exposing her bare midriff. It had set Kieran off down the path of imagining what it’d be like if all the cubs were playing naked. He would have given anything in the world to see that.

At the midway point, play paused and the girls all gathered around their coaches and munched on orange slices and sucked down juice boxes that one of the parents must have brought. The teams then switched sides, giving Kieran a whole [i]new[/i] set of cubs to gawk at. After about an hour, the matches had come to an end. At the end, the girls from both teams formed two lines and held out their paws, walking past one another to give halfhearted high-fives and “good games” to the opposing players.

Kayla chatted with her friends a bit and they gave each other hugs before she finally ran back over to her brother. 

“So!? What’d you think of the game!?” she asked him excitedly.

Kieran smiled, answering sincerely. “I liked it. It was a lot of fun.”

“Really!?” Kayla seemed genuinely shocked by his response. Granted, she didn’t exactly know the [i]reason[/i] he had found it so entertaining.

“Yeah. You did really good too.” He smiled warmly at his little sister and tussled her hair affectionately with his paw.

Kayla acted embarrassed, blushing a little, but smiled. She gave a quick peek over to her friends to make sure they hadn’t seen the sibling display of affection; luckily, they all appeared to be distracted in conversation to have noticed.

“Thanks,” Kayla replied with the same warmth, looking up at Kieran, beaming. It had meant a lot to her that he had come to her game and enjoyed it. The compliment about her skills was just icing on top.

The two climbed back into the minivan just as the rain started to really come down. Thunder rumbled the dark sky overhead and the cubs and their parents still mingling about outside the field house started to dash to the safety of their cars. Kieran started up the van and before long, they were back on the road headed home.

It didn’t take long for the steady motion of the car and the sound of the rain to lull Kayla, who was already tuckered out from her morning volleyball game, into a deep sleep. Kieran would occasionally look over at his little sister and smile; he couldn’t get over just how cute she was, sleeping there in her uniform. Her arms were draped to the sides and her head was hanging to the right, touching her long ears against the window.

Then a more primal part of Kieran’s brain seemed to take over as he looked down at her lap and swallowed. Her skin-tight shorts were an alluring temptation for the already aroused teenager. He felt guilty for a split second but then remembered it was [i]his[/i] turn to seek retribution for last night’s events. Besides, [i]shouldn’t[/i] he get a prize for having won their little contest? He did make her come first after all.

Keeping his eyes on the road, he reached over and placed his paw between her legs. Even through her shorts Kieran could already feel the intense heat radiating from between her legs. Slowly and carefully, so as to not disturb her sleep, he started to paw his little sister through her volleyball shorts. Within a few seconds, Kayla was already unconsciously spreading her legs apart as her body tried to give better access to whatever was making it feel good.

Gradually, Kieran increased the pressure and speed of his paw. After another minute or so, Kayla’s breathing had become audible over the road noise and rain as the pleasure she experienced grew. 

“Kieran…” she moaned softly.

Kieran quickly looked over in a panic as his little sister moaned his name, but saw that she was still soundly asleep.

“Holy shit! Is she having a dream about me!?” Kieran excitedly wondered. Even if said dream [i]was[/i] being initiated by him pawing her, the fact remained that it was [i]his[/i] name she had moaned in her sleep.

Emboldened by Kayla’s apparent enjoyment, Kieran decided to take things up a notch. He lifted her dark blue jersey enough to find the waistband of her shorts. He snaked his fingers underneath the elastic, being sure to get underneath her underwear too. The warmth of her bare body against his paw pads was unmistakable. He slid his paw down further until he felt his fingertips graze her delicately soft, squishy pussy lips.

Kieran slid a finger between Kayla’s labia and down her slit. He felt his fingertip glide over the nub of her clitoris. His finger continued traveling downwards, passing over the ridges of her inner labia before finally stopping at her entrance. He applied light pressure, pushing the pad of his fingertip ever so slightly inside of Kayla’s vagina. She was wet.

He wiggled his finger back and forth, pressing lightly against her hole over and over. Gradually he coated his fingertip in her natural lubrication as it leaked from her vagina. Feeling that it was sufficiently wet, he slid his finger back up until he felt the familiar bump of Kayla’s clitoris. Slowly and methodically he started to rub it in circles. 

The effect was almost immediate; her breathing became raspier and she let out another small, quiet moan in her sleep. “Her moans are so cute!” Kieran thought to himself with a proud smile. After double checking that his little sister was still asleep, he kept his fingertip circling at a slow and steady pace as to hopefully not wake her. The small, sensitive nub was getting harder and harder as Kieran continued to stimulate it.

Kayla’s hips rocked gently, pressing her genitals against her big brother’s paw, all while remaining sound asleep. Her breathing grew heavier and she moaned again. She was getting close.

Kieran increased the pressure her was applying with his fingertip and rubbed faster. Kayla whined in pleasure as she started to climax. Her eyes shut tighter and powerful waves of pleasure coursed through her sleeping body. Kieran smiled; there was something so satisfying about making his little sister come. Her legs tensed and her shoes kicked against the bottom of the dash, startling her awake.

“K-Kieran?” Kayla asked in a sleepy, thready voice. Her eyes shot open and she started to piece together what was going on. Kieran’s paw was still buried in her shorts, fondling her privates. He withdrew it and looked over at Kayla, a grin smeared across his face.

“Have a nice nap?” Kieran asked playfully.

Kayla’s face turned beet red as she realized her brother had just masturbated her to orgasm while she was asleep. She was too stunned to respond, but the truth was she [i]had[/i] been dreaming about Kieran. Only in her dream, he had been using his tongue instead of his fingers.

“Meanie!” Kayla called out at her brother, feeling incredibly embarrassed. Kieran just threw his head back and laughed, his attention then returning to the road. Kayla’s gaze fell upon his lap where his rock-hard cock was tenting his pants. She reached over and groped him through his pants, trying to get him back.

“Hey! I’m driving!” Kieran shot back, suddenly more concerned with safety. Kayla pulled her paw back and scowled at him. 

The little bunny girl felt her heart skip a beat in excitement as she came up with a plan. “You know...we never did say what the prize was for that game we played the other night…” Kayla’s voice was now much more quiet and shy as she spoke.

“Oh?” Kieran’s eyebrow lifted with intrigue as he wondered where she was going with this. He kept his eyes focused on the road.

“Yeah. Well...” she continued, “What if the prize is that the loser has to do whatever the winner wants for a day...or something.” She tried to act as casual and nonplussed about it as she could, but Kieran easily saw through her thinly veiled desires. She wanted more, but she was too shy to ask for it. The deal clearly benefited Kieran, or had she forgotten that she had lost?

Kieran decided to play along.

“Okay – deal,” he said, making sure to keep his eyes forward to not accidentally give away that he was aware of her intentions. It felt like it was a delicate offer and if he made her feel more embarrassed that she might take it away. Out of the corner of his eye he saw Kayla wiggle a little in her seat.

This part of the drive home took them along country roads as they traveled between towns. Kieran slowed the van, turning off the main stretch of road and onto a smaller dirt road that went on for miles. A little bit down the road there was a small pullout to the right where Kieran pulled off and parked. The small clearing was surrounded on the side by thick, lush foliage that looked even greener than usual in the rainstorm.

“What are we doing?” Kayla questioned, looking back over her shoulder to see if there had been cars behind them or something. Nothing. She honestly didn’t know whether the small dirt road was part of the way home or not, but when Kieran pulled over she figured something was up.

Kieran turned the key, shutting off the engine, leaving nothing but the sound of rain calmly pattering against the van’s metal roof.

“Well, you said the loser had to do whatever the winner wanted, right?”

Kayla nodded anxiously.

“Well, and [i]I[/i] was the winner – if you remember.”

Kayla looked a little nervous, wondering what exactly Kieran had in mind.

He unbuckled his seatbelt and crawled over the center console, into the back of the van. He passed between the two captain’s chairs that made up the middle row before taking a seat on the large bench in the very back. Kayla looked back over her shoulder at him. Kieran motioned for her to follow. “C’mon.”

The young bunny cub unbuckled her seatbelt and climbed into the back, following the path her brother took. Once she was standing between the two chairs in the middle of the van, Kieran held up a paw, gesturing for her to stop. Kayla was still short enough, and the van tall enough, that she was able to comfortably stand up inside – though her long, floppy ears did bend and brush against the roof.

Kieran took a minute to look his little sister up and down. He couldn’t get over how adorable she was dressed in her volleyball uniform! The striped blue jersey was a bit loose on her small frame. This was contrasted of course by her black, skin-tight spandex shorts. Below that, her soft, black knee pads clung around her legs – a stark difference in color from her light, white fur. And finally, on her feet: a pair of white tennis shoes with light blue markings and purple rubber soles.

Kayla stood there patiently, her arms at her sides, awaiting her brother’s next instruction.

“Alright, now...turn around and get in the ready position,” he supplied.

Kayla’s head cocked to the side, her ears flopping over cutely, a confused expression on her face. “Like...for volleyball?”

Kieran nodded affirmative. “Yeah, like before the ball is served.”

Kayla shrugged, finding the request rather strange. “Why would he want me to do that?” she pondered. Still, she did as she was told, turning around in place and spreading her feet apart, widening her stance. She squatted down slightly, holding her arms out in front of her as if ready to receive the ball. Kieran was treated to the view from the game once more. He smiled, noting that the pantyline in her shorts was even more visible now that he was up close.

“Alright, turn around again.”

Kayla complied, turning to face her brother. 

“Take off your shorts.”

Kieran watched as she gripped the hem of her shorts and pulled them down. She bent down, pulling the tight, black shorts over her knee pads and finally her shoes with a little difficulty. Kayla dropped the shorts of the floor and stood up straight again. Finally, Kieran got to see exactly what his little sister was wearing underneath her volleyball shorts. A pair of pastel purple panties, covered with purple flowers of all different sizes and with a dark purple hem, clung around Kayla’s slim waist.

“Wow...those are some pretty [i]girly[/i] underwear,” Kieran teased. He knew she was a bit of a tomboy and that the comment would get under her fur.

Kayla blushed, covering herself slightly. “Well I [i]am[/i] a girl,” the bunny cub retorted in a mocking tone, trying to turn it back on her brother like he was the dumb one. She stuck out her tongue and shook her head a little, her ears to brushing against the ceiling.

“Oh yeah?” Kieran teased again as if he wasn’t so sure, despite the fact that he could already make out the outline of her pussy lips pressing against her panties. “Let’s just see about that,” he added, leaning forward and grasping the sides of her underwear in his paws. Kayla nervously held her arms against her chest, her paws underneath her chin as her brother moved to undress her. Kieran started to pull down his little sister’s purple panties, slowly uncovering her small slit that was hidden within them.

The bunny teen swallowed audibly as his eyes fell upon that beautiful thin line between Kayla’s legs; never before would he have thought that such a simple shape could be so arousing. “Yup, I guess you [i]are[/i] a girl after all,” he finally spoke, sounding a little bit like he was in a trance. Kayla continued to stand still as her older brother pulled her underwear further down, over her knee pads. When he got to her feet, he held the leg holes open wide so Kayla could pull her tennis shoes through. As he moved to set the soft, purple, cotton garment down, he felt just a hint of dampness coming from the crotch.

He returned his attention to Kayla, who stood before him in her volleyball outfit – only now, she was completely bottomless. Her blue jersey hung down to just past her pubic bone, meaning her bare mound and slit were still completely exposed. Kieran looked her up and down, imagining how marvelous it would have been if all the cubs had been dressed [i]this[/i] way for the game.

“’Kay, turn around and get in the ready position again,” Kieran said, finally breaking his eyes away from Kayla’s half-naked body and looking up into her eyes. She was looking back down at him, a hint of nervousness and excitement behind her gaze. Kayla simply nodded. She turned around in place and assumed the ready position again, bending her knees and sticking out her butt as she squatted forward.

Even Kieran had to blush as his little sister presented her bare hindquarters to him. The position put both of her holes on full display as she squatted and leaned forward in front of him. Her vulva flattened and spread slightly, revealing a hint of delicate pink. 

“Spread yourself with your paws,” Kieran instructed.

Kayla hesitated for just a second, but then reached back, gripping her butt cheeks in each of her paws, spreading them apart. The motion stretched her asshole a little more and pulled her pussy lips apart, enough that he could clearly make out the hole that was her entrance, leading into her depths.

Kieran leaned back in the van’s seat to take in the full sight, his paws sliding along the bench as if he was holding himself up straight. His fingers grazed against something smooth that had gotten shoved into the crack of the seat. Kieran turned to look at what it was: a blue Sharpie marker that had fallen out of Kayla’s backpack at some point.

He had an idea. 

“You can let go.”

Kayla released her grip on herself, putting her arms back together in front of her as that’s what felt natural when she was in the ready position. Meanwhile, Kieran picked up the marker in his paw, giving it a quick once over to verify that it wasn’t dirty. Satisfied that it was clean, the teenage bunny leaned forward and reached out towards his cub sister rear end. He slid the back end of the marker into her slit and guided it towards her entrance. Slowly, Kieran started to push the gray barrel of the marker into Kayla’s vagina; he was amazed at the ease with which it slid into her. Kayla let out a slight gasp as the marker entered her.

Kieran thrust the marker in and out of her a few times, fucking her little pink bunny hole with it gently. Finally, he pushed it in far enough that most of it was buried inside of her; only the blue cap and a little bit of the gray barrel remained outside of her body. Kieran let go and sat back, admiring the view. The marker stayed firmly in place without his assistance, sticking out of his Kayla’s love tunnel thanks to her small size and overall tightness. Kayla just stood there patiently, believing that Kieran had stuck his finger inside of her.

After a minute or so, Kieran leaned in and gently pulled the marker back out. There was a very quiet, wet pop as it vacated his little sister’s body. He looked down at the marker, noticing that it looked shinier than before; a fair amount of it had been coated in Kayla’s clear, slick juices.

However, Kieran’s eyes were now drawn upwards, to the puckered, pink flesh of Kayla’s virgin tailhole. He brought to marker up and leveled it with her asshole. As soon as it touched her sensitive ring of flesh, Kayla reflexively jerked her hips forward, her butt cheeks clenching tightly together.

“Hey! What are you-!?” she shouted, looking back and over her shoulder. It was then that she saw the Sharpie in Kieran’s paw. “Is that a [i]marker[/i]? Were you trying to stick a marker in my [i]butt[/i]!?”

Kieran just grinned up at her. “Hey – I’m supposed to get to do whatever I want with you right?”

“NO!” Kayla shouted back at him. “[i]I[/i] have to do whatever you want!”

Kieran gave a shrug and rolled his eyes. “Whatever. Same thing.”

“Nuh UH!” Kayla retorted with a typical juvenile cadence.

“Fine! Then what I [i]want[/i] is for you to get back in the ready position and let me do whatever I want, [i]okay[/i]?”

Kayla pouted. She had been tricked!

Alas, she couldn’t find any flaws in her big brother’s logic, and that [i]was[/i] the deal, so she slowly bent her knees again, looking forward and getting back into the volleyball ready position. Her holes were put back on full display for Kieran.

“Just relax,” he suggested in a soothing, reassuring tone. He placed one paw on her bare, left cheek as he lined up the marker again. He heard Kayla let out a self-calming breath and watched as her asshole visibly relaxed some with the rest of her body.

Gently, he started to push the end of the marker against her tailhole. After a little bit of resistance, the marker finally popped inside the tight ring of flesh. Kieran continued to push the marker deeper into his little sister’s ass. The marker slid in fairly easily, thanks to being lightly lubricated with Kayla’s own excitement.

The young bunny cub kept her eyes shut tightly, her face scrunched up as she felt a whole new sensation coming from her small tailhole. She had been worried that it would hurt, but to her surprise, it didn’t. In fact, it was kind of tingly – maybe even in a good way. Not that she’d ever admit that to Kieran; she was so embarrassed! She couldn’t believe that she was letting him shove one of her markers from school inside her [i]butthole[/i]!

Kieran continued to push until finally the edge of the cap, and the clip on the side of it, pressed against Kayla’s flesh. He stopped and let go of the marker, leaning back a little to get the full picture again. Like before, the marker stayed very much in place. He looked lustily at the tight hole; wrinkled, pink flesh squeezed the marker snugly from all sides, holding it there. It looked kinda funny, seeing just a little blue cap sticking out from her butt.

“Hey, stand up straight,” Kieran instructed.

Kayla stood back up, her cheeks coming together, closing in around the marker. Now, only the very end of the blue cap was peeking out, the rest of it having been engulfed by her small, firm, toned butt. It was like a little indicator, showing exactly where along her crack her normally hidden tailhole lay hiding.

Kieran spoke, “Lean forward again and push it out.”

Kayla squatted but then asked, “What do you mean [i]push it out[/i]?”

“Ya know, like, squeeze your muscles.”

Standing in the ready position, Kayla clenched her abdominal muscles down and gradually the marker started to smoothly emerge from her asshole. She continued to push; more and more of the marker appeared until finally gravity took over, pulling out the last little bit as the Sharpie fell to the floor of the van. Kayla giggled and turned around.

“It’s like I pooped out the marker!”

Kieran just rolled his eyes and shook his head. “Dork.”

Kayla stuck out her tongue again, giving Kieran yet another idea.

“You should suck me,” the bunny teen suggested.

That made Kayla quiet down quick; her expression turned timid and her face flushed red. “Like, another blowjob?”

Kieran just smiled, his face giving her all the answer she needed. Kayla nodded obediently and got on her paws and knees, crawling over to the rear seat. As she neared Kieran, she reached out to pull down his shorts. Kieran lifted his hips and helped her out a little, pushing them down some. Kayla took over and pulled them down, along with his underwear, finally freeing his eager, stiff cock. It bounced back after being dragged down by his shorts, slapping against his belly before standing straight up. Kayla pulled his shorts down the rest of the way until they were down around his ankles.

An ample amount of precome was leaking from Kieran’s uncut cock, mostly from the show that his little sister had just put on for him and playing with her half-naked body. Kayla’ paw closed around his length as she moved her head in closer. The young bunny girl looked up into her brother’s eyes as she stuck out her tongue and started to lick the bottom of his glans, causing Kieran to exhale deeply as sudden wave of pleasure rippled down his legs and up his spine. His cock throbbed, pushing another sizable drop of clear precome out of his tip.

Kayla licked up her big brother’s excitement and finally broke eye contact, opening her mouth wide and taking him inside. Her lips closed around his shaft and her tongue pressed against the bottom of his length. She started sucking on him like a lollipop, bobbing her head up and down, taking a little bit more of him into her warm, wet mouth.

Kieran laid his head back and stared up at the ceiling, relishing in the feeling as his little sister gave him head in the back of the family minivan. He closed his eyes, listening to the relaxing sound of the rain against the metal roof, broken only by the occasional sucking sound that escaped when Kayla’s lips would lose their normally airtight seal around his cock. 

Kieran finally lifted his head, looking down at Kayla, whose mouth was still diligently at work; his eyes traveled downward from the large, white number ‘7’ on the back of her jersey, and down past her fluffy tail to her bare bottom and thighs. Unfortunately, from this angle he couldn’t see much more than the tantalizing curvature of her ass and the top of her crack.

He wanted more.

Gently, Kieran grasped Kayla’s shoulders, pushing her away enough to indicate it was okay to stop, even though she had only started a little bit ago. The young bunny cub lifted her head, looking somewhat confused, rising up so she was standing on her knees between Kieran’s legs. She looked up her big brother innocently, wondering what was next or why he had made her stop. After all, he hadn’t shot that white stuff out yet...

After a moment, he finally spoke, breaking the silence. “You wanna...do it?”

Kayla blushed and bit her lip in excitement before nodding shyly, her ears flopping as her head rocked back and forth.

“Me too...” Kieran added, trying to show his sister his own excitement so she didn’t feel so embarrassed. Kayla smiled warmly. There was clear twinkle in her eyes.

“You should climb in my lap and ride me,” the teenage rabbit suggested.

“’Kay,” Kayla replied in a cute, quiet voice. She wasn’t exactly sure how to do that, but she was sure she would have her big brother’s instruction and support.

He held out his arms, offering for her to climb into them. Kayla got up off the floor and crawled into her brother’s lap, facing him. As she moved closer, Kieran’s eyes fell upon the patch on the left, front breast of Kayla’s jersey. “BSS Girls’ Youth Volleyball Club,” was written around the outside of the patch with a large white volleyball adorned with a pink bow in the middle. A tinge of both excitement and guilt rushed through Kieran’s mind as he remembered just how young his little sister was. Was this really okay?

It was quickly pushed out though as his teenage lust demanded satisfaction; besides, he had asked her if she wanted to and she had said yes, right? She [i]wanted[/i] to – he wasn’t even forcing it with the “prize” of her doing whatever he wanted.

“You sure you want to do this?” Kieran asked again. “Have sex?” he added for clarification, just in case.

Kayla smiled and nodded, her face and ears still pink. She spread her knees to the sides and got in Kieran’s lap. Her knees pushed into the crack between the seat bottom and the seat back on either side of him. Her feet splayed out to the sides, the purple soles of her shoes exposed as her feet smooshed against the soft seat. Kayla brought her body in close to Kieran’s, putting her arms around his neck. Their faces were close, close enough that they could feel each other’s breath. The two siblings locked eyes, sharing an intimate moment as Kayla hovered above her big brother’s erection.

“What now?” she asked innocently, her voice small.

Kieran took a second to respond, getting a little lost in Kayla’s eyes and the surreal nature of the whole situation. “Ahem, so now, you’ll want to guide my dick as you lower yourself down onto it. Just go as slow as you need to, okay?”

“Mhmm,” Kayla responded in the affirmative, nodding her head and smiling softly. She reached down the space between their bodies and between her own legs. Her small paw grasped Kieran’s uncut cock gently and held it in place. She had tilted her head down so she could see, her ears flopping against her brother’s face. Watching closely, she started to carefully lower herself down.

The head of Kieran’s cock slipped between Kayla’s soft pussy lips. She let go of him and maneuvered her hips, guiding him back towards her entrance. She had to push a little to get him inside, letting out a small gasp as his tip spread her open. Even Kieran’s let out a quiet, pleasured sigh as his cock sank into his little sister’s warm depths. The walls of her vagina were so delicately soft, so intensely tight, that it felt like she was melting all around him.

Kayla continued to lower herself further and further down, impaling herself on her brother’s mast until finally her legs pressed against his thighs. She had bottomed out, unable to lower herself further even if she wanted to. To both bunnies’ amazement, nearly all of Kieran’s length was buried inside of Kayla’s small body.

They both sat there for a moment, breathing a little more heavily than normal, as they adjusted to the feeling of being so intimately connected.

“Now what?” Kayla finally asked, her voice a bit thready.

“Now, just bounce up and down, grind around, whatever feels good,” advised Kieran, wanting Kayla to take the lead. Not only for the sake of her comfort, but there was just something so satisfying about having her make him cum with little to no intervention.

Kayla started to lift up, dragging herself back up her brother’s length. She neared the top, reversing directions and sliding back down. As she got more confident, she started to move a little bit faster. Before long, she was bouncing steadily in Kieran’s lap, plunging him in and out of her tight, wet hole. The sound of her ass slapping against his thighs and a subtle, wet squishing joined the symphony of rain falling on the van.

Kieran’s eyes drifted to the rear-view mirror as his little sister continued to fuck him, bouncing energetically as she tried to find a pace that felt the best. He noticed the pine tree air freshener that was dangling from the mirror, gently swinging back and forth in time with her movements. He wondered just how much the van was rocking from the outside. Would anyone have been able to tell?

However, his attention quickly return to Kayla as she slammed herself all the way down on his cock and started to rock her hips instead. The ten-year-old bunny cub was extremely aroused, and Kieran was exactly what she needed. Kayla let out sweet, rhythmic moans as she ground her hips against her brother’s lap. Her pace was incredible, likely something only a cub would be capable of. While she stirred around her insides with the full length of her brother’s cock, she was also rubbing her clitoris against his pubic bone, providing even more exciting stimulation.

Through the sound of the rain and his little sister moaning in his ear, Kieran managed to hear the sound of tires rolling over gravel. He quickly panicked, trying to look out the windows of the van for the source; his panic settled some as he realized all the windows were completely fogged over from their exertions. Still, the van was likely rocking, at least perhaps enough to be noticed, but he knew there was nothing that he could do. The silhouette of another car passed by, not even slowing down in the slightest. They were safe.

Kayla had been completely oblivious to the whole event; she was too concentrated on her own sexual pleasure to even notice. The young bunny cub continued grinding her hips forcefully, moaning when her sensitive clit would rub against Kieran’s pelvis.

“Does it feel good?” Kieran asked, already knowing the answer from his little sister’s pleasured expression. Kayla opened her eyes lazily and looked at her brother, nodding in an almost drunken manner as she continued to rock her hips. Her breathing had become even heavier; she was practically panting at this point.

“How good does it feel?” Kieran asked playfully.

“R-really...really…g-good…” Kayla responded, smiling slightly, her voice catching in her throat occasionally.

“You like the feeling of my cock inside your pussy?” Kieran asked lustfully, getting more explicit with his questioning.

“Y-yeah,” Kayla responded back. Her face was completely flushed, but whether that was from embarrassment or exertion, Kieran wasn’t sure.

“Say it,” Kieran added bluntly.

“Y-your cock...feels really…gooOOOod...in my...pussy,” Kayla managed to stutter out between moans.

Hearing those words come out of his sister, in her sweet, girly cub voice was more than Kieran could handle. He hadn’t realized just how close to cumming he was; Kayla’s relentless thrusting had driven him closer and closer to the edge, and her words had finally pushed him over.

“Uhhn! Kayla!” was all that Kieran managed to moan before his climax overtook him.

Powerful jets of cum rocketed up into Kayla’s tiny body. But despite a sudden burst of warmth, Kayla hardly even noticed that her big brother was cumming; she kept on riding him at the same relentless pace, entirely focused on her own pleasure, her own climax building quickly. Kieran moaned as intensely pleasurable waves cascaded through him. The fact that his orgasm had been brought about entirely by Kayla’s own movements as she sought her own release, and the fact that she didn’t stop moving, even as he was cumming, made the bunny teen’s climax all the more potent. Kieran’s cock pulsed strongly inside of Kayla, throbbing against her walls, pumping the rest of his load deep within her.

Kayla whined in pleasure, her thrusts becoming blindingly fast as she made herself cum on her brother’s cock. Suddenly, she stopped moving entirely, holding herself still as the pleasure simply became too much for her to continue on. Her lips parted as she silently moaned, her breathing unsteady. Kieran knew at once that his little sister was cumming. He watched her expression twist into one of agonizing pleasure. Then, without even thinking about it, he kissed her. Kayla’s arms closed tighter around her brother’s neck as she kissed him back, moaning softly into his mouth. The kiss just drove the young cub wilder; her small body trembled against Kieran’s as it was overwhelmed with sensations.

The pair maintained their long kiss throughout Kayla’s climax. When it finally ended, they both pulled away, a thin strand of saliva stringing between their lips before disappearing. Kieran and Kayla looked at each other in disbelief, like they couldn’t comprehend what had just happened. Both of their faces were flushed with embarrassment.

“T-that was my first kiss,” Kayla admitted shyly.

Kieran smiled but Kayla’s expression soured.

“THAT WAS MY FIRST KISS YOU MEANIE!” she restated, yelling a little this time. She started pounding on her brothers, her small paws clenched into fists. Her strikes weren’t very powerful, but enough that they hurt a little.

“Hey! HEY!” Kieran shouted back, grabbing Kayla’s arms and restraining her. She quieted down and listened, scowling at her big brother.

“Would it make you feel better if I told you it was [i]my[/i] first kiss too?” Kieran asked, smiling.

Kayla’s mouth opened as if she was about to say something but then she stopped. Her expression softened. “Really?”

Kieran nodded. “Mhmm.”

Kayla smiled softly; evidently that did make her feel better.

The two just sat there for a moment, still intimately joined, listening to the sound of the rain outside.

“We should probably be getting home,” Kieran acquiesced. “Mom and dad are probably getting worried.”

Kayla nodded in agreement, going along with her big brother’s advise. She lifted herself up and Kieran’s softening cock flopped against his belly. Cloudy, white cum poured from Kayla’s slit, dripping onto Kieran’s shaft and balls before dribbling down onto the seat. Kayla stood up, using her paws to pull back and spread her pussy as she looked down to try and see if any more of Kieran’s cum was coming out.

There was a small, old pack of tissues in one of the seat back pockets that Kieran used to try to clean himself up and wipe up the seat the best he could. He pulled his shorts back up and watched as Kayla got dressed. She kicked off her shoes to make it easier to put her clothes back on. Kieran was amazed as he watched Kayla’s half-naked body transform from being naughty and sexual, back to an innocent-looking cub, ready to play volleyball as she pulled up her shorts and underwear.

After they were both dressed, they climbed back into the front seat and Kieran started up the van. He had to put the defroster on maximum with the A/C cranked up for about five minutes before the windows finally became transparent again. With a quick u-turn, they were headed back down the dirt road and out to the highway home. 

Kayla stared out the window at the passing landscape as they headed back into town. She was smiling the whole time, replaying her kiss with Kieran over and over in her mind. Kieran’s voice startled her a little out of her daydreaming when he finally spoke.

“Hey, when we get home, if mom and dad ask – we’re late because we stopped to get ice cream after the game, okay?”

Kayla gave a single understanding nod and saluted. “Roger!”

Kieran shook his head and rolled his eyes affectionately. “Dork...”

Twenty minutes later they were pulling into the driveway and parking in front of their house. Kieran and Kayla hopped out of the van and went in through the front door.

“Hey guys! Where have you been?” the cubs’ mom asked cheerfully, stopping momentarily from dusting one of the lamps in the living room.

“Kieran took me for ice cream!” Kayla quickly answered excitedly. She threw her arms around her brother’s waist, giving him a hug.

“Aww, that was nice of you Kieran!” their mom cooed, proudly beaming at her son.

“Yeah, well…” Kieran replied a bit embarrassed. He rubbed the back of his head with his paw awkwardly.

“I’m so happy to see you two getting along for once!”

“Mhmm! Mhmm!” Kayla responded, nodding happily.

“Yeah, I really liked taking her to the game actually – we had a lot of fun,” Kieran admitted.

“Well [i]good[/i]! Maybe you can take her to some more games in the future!”

Kayla and Kieran looked at each other and smiled slyly as their mother resumed cleaning.

“Yeah...maybe…”
