The tires of the minivan and accompanying camper crunched loudly across the loose gravel of the campsite as the family of bunnies arrived. Kayla quickly unbuckled her seat belt and threw open the side door, jumping out and bounding towards the water’s edge. Kieran was quick to follow, eager to stretch his legs after the long car ride. He ran after Kayla, not bothering to close the door, calling out “Hey! Wait up dork!”

While the two cubs chased each other near the lake, their parents started to setup camp; their father busied himself with securing the camper, cranking the supporting legs into place. Meanwhile, their mother had popped the rear hatch on the van and was removing the bags, coolers, and folding chairs from the back.

Kayla had finally come to a stop, facing out towards the lake and watching the sun set on the horizon. She planted her paws on her hips, pretending to be overly dramatic and pretentious. “My, that sure is a gorgeous view,” she announced in a fake, deep voice, mocking what a grown up might say.

Unbeknownst to her, Kieran was creeping up silently behind her, stalking her as a lion would stalk its prey. Kayla’s fluffy, white tail was peeking out from between her shorts and shirt, standing out against the dim light, helping provide a target. Her brother raised his paws as he neared and prepared to strike. 

“It sure…..[i]IS[/i]!” At the same instant he said the final word, he struck; in one quick motion he yanked down his little sister’s shorts and underwear, all at once, exposing her bare ass. They fell around her ankles, leaving her standing half-naked on the beach.

“KIERAN!” Kayla shouted, her cry echoing out across the water – away from their parents, luckily. She quickly bent down to pull her pants back up, giving Kieran a fleeting glimpse of her pussy as her lips pouted out between her thighs. Kayla pulled her panties and shorts back into place in a blur of motion.

Kieran was guffawing at his own practical joke as Kayla spun around, glaring at him. She lunged towards him, punching him in the arm. “Jerk!” she yelled.

“Kids! Stop goofing around and come help your mom and I!” their father called out from over near the van. It seemed like neither of them were aware of Kieran’s little “prank.”

“Cooomiiing~!” Kayla responded, hurrying over to her mother’s side.

Kieran helped his dad unhitch the camper from the van while Kayla to unload the van and setup the campsite. When the family had finished, they collapsed into the folding chairs that Kayla and her mom had positioned around the campfire.

The sun had set and the full moon provided some lighting while the warm, orange glow of the campfire provided the rest.

“Who’s ready for some dinner, hmm?” their mom asked, reaching down into the cooler beside her chair and pulling out a package of hot dogs.

“Me!” Kayla eagerly cheered, hopping up out of her seat.

Her mom smiled at her and nodded towards the woods. “Why don’t you and Kieran go gather up some sticks for us to roast these weenies on?”

“’Kay!”

Kieran rolled his eyes and sighed as he stood up, being sucked into doing more work. He would have much rather just stayed slumped in his seat, but he knew his mother’s suggestion was more of an instruction.

The two bunny siblings walked slowly along the edge of the tree line, eyeing the ground and looking for the perfect sticks. After collecting the requisite number, they headed back over the fire and passed them out to their mother and father.

Soon, they were all holding their sticks over the fire, listening to the hot dogs sizzle as they slowly cooked.

The air had a quiet stillness about it. The crickets hadn’t yet started chirping but the birds had ceased their singing for the day. The silence was broken when the cubs’ mother spoke.

“So Kayla,” she started, turning her attention towards her daughter but keeping her hot dog above the licking flames. “Are there any cute [i]boys[/i] in school that you have a crush on?” she asked, her tone playful.

“Moooooom! NO!” Kayla protested, throwing her head back dramatically and cocking it sideways as she glared at her mother. Her mom smiled and laughed while her father cleared his throat.

“Good, don’t need to be chasing boys at your age anyway,” their father spoke gruffly from across the fire.

Kieran swallowed, keeping his eyes locked on his hot dog. “If only dad knew what Kayla and I got up too… [i]earlier today even[/i]…” he thought to himself, trying to make sure he didn’t look outwardly nervous. He felt like if he moved a muscle his parents would instantly becoming aware of his and Kayla’s deviousness. His attention snapped back when his mother spoke again and his ears perked.

“And what about you Kieran? Any girls in your class you’re interested in?”

He tried to speak but found his voice catch in his throat. He swallowed again, trying to reintroduce some moisture and cleared his throat. “Ahem. Uh, not in my class...no.”

“Oh? But there [i]is[/i] a girl?” She had caught the nuance of what Kieran had said.

“Y-yeah… I guess you could say that,” Kieran replied.

Kayla’s eyes opened wide and she looked at her brother in astonishment. “What!?” she thought to herself, getting a sinking feeling in her chest.

“Well! Tell us about her!”

“Well...her name is...Mandy and she’s uh, younger than me. The, uh, grade below me,” he clarified, feeling a tinge of guilt.

Kayla’s expression soured as she listened to her brother talk.

“How long have you had your eye on her?” their mother continued.

“I dunno, maybe like, a month? Can we...not talk about this?” Kieran asked, becoming rather embarrassed.

“Okay, okay. Fine! You guys are no fun!”

The family ate their hot dogs in relative silence, with the crackling of the fire providing the ambiance. When they had all finished, they continued sitting there for a while, enjoying the peacefulness of nature. Kayla looked distant, staring into the fire, but nobody seemed to really notice.

Their father yawned, causing Kieran to yawn in turn.

“Well, I think it’s about time for bed,” their mother noted, standing up from her chair and picking up the rest of the hot dogs and buns, storing them in the cooler.

Kayla, Kieran, and their mother walked over to the camper while their dad stayed sitting by the fire a bit longer. Once they reached the door of the camper, the cubs’ mother addressed her son.

“Alright, you know the drill. Kayla and I will go inside and change while you wait out here and then once we’re ready I’ll call and you can come inside.”

“Yeah, yeah,” Kieran replied, having heard and followed these same instructions for years. He leaned against the camper as his mother and little sister went inside, closing the door behind them.

After about two minutes, Kieran’s mother called out to him. “Okay! You can come in now!”

Kieran turned on his heel and opened the door, climbing up into the camper. The lights were already off making it difficult to see, at least until his eyes adjusted. He could make out the lump that was Kayla underneath the covers of the top bunk and his mom’s head against her pillow on the lower bunk.

The teenage rabbit undressed for bed, starting with his shoes. He pulled his shirt off over his head and pulled down his shorts leaving him in only his boxers. He kicked his discarded clothes aside so their father wouldn’t trip on them and climbed up the ladder up to the top bunk.

He crawled underneath the covers with Kayla. They had always slept together in the top bunk, ever since they were little. Luckily the bed was large enough to accommodate.

Kayla was facing away from him towards the back window of the camper, laying completely still aside from her slow, steady breathing.

“Hey,” Kieran whispered to Kayla. “Hey, you awake?” he repeated.

Kayla didn’t answer or budge.

“She must have fallen asleep already…” Kieran thought to himself, a little disappointed.

After another ten minutes, the cubs’ father finally came to bed and got into the bottom bunk with their mother.

Kieran waited another five minutes or so before finally trying to rouse Kayla once more. He thought that maybe she was keeping quiet until their parents were asleep. It was almost like a tradition for them to stay up later than their parents, whispering and cracking jokes.

“Hey,” Kieran whispered, shaking Kayla’s shoulder gently.

She quickly pulled her shoulder away from his paw and made a grumpy sound.

“So you [i]are[/i] awake!” he whispered a little louder.

Silence.

“C’mon, Kayla – are you mad at me or something?”

Kayla finally rolled over in a huff, glaring at her older brother. Despite the darkness, Kieran could see that her eyes were misty. 

She was clearly upset.

“W-what’s wrong?” Kieran asked, genuinely shocked to find Kayla with tears in her eyes.

“Why don’t you just ask [i]Mandy[/i],” she said derisively.

Kieran blinked a few times, confused.

“Is [i]THAT[/i] what this is about?” he asked a bit louder, but still whispering.

Kayla nodded, frowning the whole time. Her nose wrinkled up in an angry glare, her brows furrowed.

Kieran rolled his eyes. “Oh jeez, c’mon dummy! Mandy isn’t real! [i]I made her up[/i]!”

Kayla’s expression softened, morphing slowly to confusion and cautious hope. “R-really?”

Kieran smiled softly and nodded. “Yup. I made her up because I knew mom would just keep pestering us if I didn’t give her some kind of answer.”

Kayla finally smiled back, a wave of relief washing over her, her whole body visibly relaxing.

“But,” Kieran continued, “part of what I told mom was true…”

Kayla cocked her head to the side, becoming a little tense again, waiting for her brother to explain.

“I [i]am[/i] interested in someone...and she [i]is[/i] younger than me…”

His little sister’s expression didn’t change; she was clearly waiting for him to explain. Anxiety made her heart skip a beat or two, worried about what he might say.

“[i]YOU[/i] dummy!”

Kayla immediately blushed and turned her face into her pillow to hide the fact. A few seconds later she turned it back, a big grin on her face.

“Yaaay~!” Kayla whispered excitedly.

Kieran stifled a quiet laugh at her adorableness.

The two siblings gazed into each others eyes for a bit before Kieran finally spoke up.

“Kayla…,” he whispered softly.

“Hm?”

“...I love you,” Kieran added.

Again Kayla’s face flushed and she buried it in her pillow. With her face still hidden she answered back. “I...love you too.”

They had said the phrase to each other before, but never with so much [i]meaning[/i].

Their hearts were both pounding, thumping loudly in their ears.

“Hey Kayla…” Kieran whispered.

She turned her head back towards him, her cheeks pink. “Yeah?”

“You wanna...?” Kieran wiggled his eyebrows to convey his meaning, rather than risk voicing it where their parents could possibly hear.

Kayla’s eyes went wide and her mouth opened. “I...I mean I [i]do[/i]...but...what about mom and dad?”

“We could just be really quiet. They’re both sound asleep – I don’t think they’d wake up. And even if they did we could just make something up...like you were stealing the covers or something.”

Kayla nodded excitedly.

Kieran reached out for her underneath the covers. His paw touched her stomach.

“I’ve been wanting to do more with you ever since that rest stop,” Kieran said softly, guiding his paw down her body. He wedged it underneath the waistband of her shorts and underwear, his palm sliding over her smooth mound.

“Me too,” Kayla whispered back, reaching out with her own paw. She fondled Kieran’s member through his boxers, feeling that he was rapidly becoming hard.

Kieran slipped his middle finger between Kayla’s pussy lips. He moved it around, feeling the nub of her clitoris and her soft inner folds shift and slide underneath his fingertip. The young bunny cub was already a bit wet.

Kayla drew in a sharp breath through her nose as her big brother stimulated her magic button. Kieran smirked in response, proud of the effect he had on his little sister. She rotated her leg up, lifting it under the covers and giving Kieran better access.

Taking full advantage of this, Kieran shoved his paw into her shorts further. His finger slid deeper between her lips before eventually finding her hole. Kieran curled his finger inwards, inserting it into Kayla’s vagina. He wiggled his finger around, feeling just how soft and warm it was inside of her.

He withdrew his paw from her shorts, feeling a bit of her wetness still clinging to his finger.

“How should we do it?” Kayla whispered, even quieter than normal, lowering her leg back down.

“Hmm,” Kieran thought about it for a moment. “Face away from me and bring your knees up some.”

“’Kay.”

Kayla did as he asked, rolling to face away from him and sliding her knees towards her body, getting into a spooning position.

“Now what?” she asked over her shoulder. Kieran was already busy pulling down his boxers.

“Pull down your underwear,” Kieran instructed.

Again, Kayla did as her big brother asked, pulling down her shorts and panties until they were around her knees. The siblings were now both partly naked underneath the covers, their eager bunny bits exposed, but hidden from view.

Kieran shuffled himself in closer to Kayla, spooning her from behind. He thrust forward, his cock sliding between her thighs, grinding against her pussy lips.

He pulled his hips back and tried again, this time attempting to use his paw to guide himself. But still, he was unable to penetrate her. Instead, his tip just smooshed against her squishy labia. He could feel the warmth radiating off of her privates, could hear her steady, breathing. 

He had to have her.

Frustrated, Kieran pulled his hips back and brought his paw up to his mouth. He gave his palm a big, slobbery lick and thrust it back under the covers. He wrapped it around his length and stroked briefly, making sure to get his tip plenty wet with spit.

It was going to work this time.

He scooted in close again.

“Alright, here goes. Make sure to stay quiet, okay? We don’t want to wake mom and dad up.”

The cubs’ parents were still sleeping soundly, not three feet from them. Soft snoring could be heard from below.

Kieran lined himself up with his paw, but this time, without realizing it, he had instead aligned his cock with Kayla’s butthole instead. 

He inched slowly forward.

As soon as his tip touched the sensitive flesh of her tailhole, she realized her brother’s mistake.

Kayla cried out in a loud whisper, “Wait! Kieran that’s-!”

But her cry was quickly silenced as Kieran threw his other paw over her mouth. He hadn’t even heard what she had said; he was too focused on trying to get things started.

“Shhhh~!”

Even as he shushed her, her muffled protests vibrated against his paw, which was still clasped over her mouth.

Kieran thrust slowly upwards and the round head of his cock, aided by the lubrication of his saliva, gradually spread the wrinkled flesh of Kayla’s asshole.

Kayla drew in a sharp breath as her anal virginity was unwittingly taken by her big brother. She whimpered softly as his cock pushed uncomfortably deeper and deeper inside of her.

Luckily, the position they were in limited Kieran’s movement, and he wasn’t able to penetrate her all the way. Still, about half of his length was buried inside of her tight a. Kieran still had no idea; he could just feel the soft warmth wrapped around his cock and assumed it was Kayla’s vagina.

He finally removed his paw from her mouth, but Kayla remained silent. It was taking most of her concentration to not cry out – something that would surely wake their parents and get them both in trouble.

Kieran started to gently thrust, the new, awkward position difficult to get used to. Kayla was grateful that at least he was taking things slow. Their shared bunk creaked ever so softly with each repetitive movement of Kieran’s hips, also urging him to be cautiously slow. Occasionally, he would pause, waiting and listening for the slight, subtle noises of sleep coming from below, indicating that they were in the clear.

As he continued to fuck her ass, Kayla would occasionally wince or whimper softly – sounds that Kieran mistook for her pleasure and enjoyment. His breathing was heavy in her ears, his paw resting on her bare hip. Kieran was getting close.

Marching ever closer to his climax, Kieran abandoned some of his caution, thrusting a little more quickly. The squeaking of the bed increased slightly and the rhythmic nature of the sound would be unmistakable to the knowing ear. Kieran’s thrusts were shallow, his cock pushing in and out of Kayla’s butthole; each time he would withdraw until his glans slipped out of her hole before plunging back in to half-mast.

With a final thrust, Kieran buried a full three-quarters of his length inside of Kayla’s butt. She let out a squeak at this surprising, new, deeper penetration. Kieran bit his lower lip to keep from moaning as his cum erupted violently inside of his little sister’s ass.

Kayla could feel a sudden burst of intense warmth and knew that Kieran had finished and this would all be over soon. She gripped the edge of the b ed tightly as she patiently waited for his climax to finish.

Kieran’s cock pulsed several more times, pumping his full load inside of Kayla’s ass. He waited until every last drop had leaked from his tip before finally moving his hips downward and sliding out of her back door. Once vacated, her tight asshole clenched back shut, trapping Kieran’s cum inside of her.

“Ahhh~!” Kieran let out a quiet contented sigh, his heart finally starting to return to a normal pace.

Kayla quickly pulled up her underwear and shorts and promptly rolled back over to face him. Again there were tears in her eyes and a scowl on her face.

Kieran looked at her stunned and confused.

“What? What’s wrong?”

Kayla started pounding on Kieran’s bare chest with her fists, the cramped space preventing her blows from even hurting. 

“What? WHAT!?” he asked, whispering urgently – very confused by this sudden turn.

Kayla finally stopped beating on her big brother and glared at him, locking her eyes with his.

“That was my [i]butt[/i]!” She whispered loudly. “You put it in my [i]BUTTHOLE[/i]!”

Kieran’s eyes went wide.

The cubs both froze as the covers from the bunk below rustled. After a few agonizing seconds, it seemed like it was probably just from one of their parents rolling over.

“Are you serious? I am [i]so[/i] sorry!” Kieran whispered quietly, but sincerely. He put his arms around Kayla and pulled her in close for a hug. Kayla snuggled into his warm chest and breathed in her brother’s scent. “I had no idea,” Kieran continued. “Seriously. I thought we were just...doing it... normally and that you were liking it.”

Kayla shook her head, her long ears tickling the bottom of her brother’s chin as she did.

“No,” Kayla murmured into Kieran’s chest, forgetting to whisper. “It hurt,” she added, whispering this time.

Kieran squeezed Kayla tighter, trying to convey how bad he felt. “Sorry,” he repeated.

After a few seconds of silence Kayla spoke again.

“...And now I really have to pee.”

Kieran released his hug. “Oh?”

Kayla nodded.

“Do you want me to move so you can get out?” Kieran asked.

She looked up at him with innocent, puppy-dog eyes before pleading softly. “C-could you come with me?”

“What? Are you scared?” Kieran teased.

“No!” Kayla replied in her normal voice.

“Shhhh~!”

“No!” she repeated, this time in a loud whisper. “I just...don’t know where to go…”

Kieran knew that she was lying and that she really [i]was[/i] scared, but too proud to admit it.

“Okay, fine. I can come with you,” he acquiesced, deciding after what just happened he didn’t want to make her feel any worse.

The bunnies climbed out of their bunk bed and down the ladder. Kieran turned the doorknob and silently swung open the camper door. He hopped out, holding the door open for Kayla who was tiptoeing behind him. Once they were both outside, Kieran quietly closed the door behind them, taking care to not disturb their sleeping parents. Kayla waited patiently for her brother to lead the way. 

The moon was high in the sky now, shining brightly and illuminating the campsite with a soft, white glow. It reflected off the lake eerily, the water very still and calm. The moonlight made the cubs’ soft white fur seem to incandesce.

“C’mon,” Kieran said, leading Kayla over behind the camper, towards the edge of the forest. It was only twenty yards or so away from the camper, so there was no reason that Kayla shouldn’t have been able to find it herself. It’s not like there was any special “spot” – just somewhere away near the trees.

“Here,” he remarked, coming to a stop.

Kayla was walking a little funny and went a bit past him before stopping and standing there.

“Well, are you gonna go or what?” Kieran asked, getting a little impatient.

“I’m waiting for you to turn around!” Kayla objected, her paws balling into fists as she defiantly thrust her arms down her sides.

Kieran was about to turn around when a thought occurred to him. “Wait a sec...you got to see [i]me[/i] pee earlier today – so it’s only fair that I get to see [i]you[/i] pee too.”

Kayla’s pink nose scrunched up and her lips pursed in a look of disapproval. She thought of the best response she could to try to still come out on top. “Nuh uh! I hardly even saw anything so it’s [i]not[/i] fair!”

Her brother shrugged. “Guess I’ll just go back inside then,” he threatened, going as far as turning around and taking a step or two away.

“No! Wait!” Kayla called out, a little bit of panic in her voice. Kieran stopped and turned around. “You can...watch me.” She gave in to her brother’s wishes.

Kieran smirked and walked back over to her.

Kayla took a deep breath as if psyching herself up before quickly pulling down her shorts and underwear around her knees as she squatted down. Kieran squatted down in front of her, his eyes trained on her pussy.

After a few seconds, a small stream burst forth from between her lips. It quickly grew to a powerful spray, pattering against the dirt between Kayla’s legs. Kieran was surprised by just how loud it was: a steady hissing as her urine left her urethra. Just another very private detail about his little sister that Kieran was now privy to.

Eventually, the stream slowed to a trickle and finally a dribble. Kayla was about to stand back up but Kieran noticed something. “Wait!” he urged, holding up his paw. Kayla stopped, and remained squatting in front of him.

Directly below Kayla, resting on top of the dirt, was a single drop of Kieran’s cum. The position she was in, along with relaxing to go pee, must have relaxed her asshole enough to let some of it escape.

“Relax again. Like you’re going pee,” Kieran advised.

“Huh? Why?”

“Just do it!”

Kayla did and her tailhole slowly opened. A large glob of semen started to slowly drip out of the young bunny cub’s asshole. The thick white fluid gradually stretched to several inches before finally falling to the ground as one. Kayla peered down between her legs, watching as well.

“It’s your white stuff! See! I told you you had sex with my butthole!” Kayla remarked.

Kieran didn’t bother to respond, opting to just watch in awe as his cum dripped out of her. He swallowed, having a sudden realization: “This means...I’ve fucked...and cum inside of...all of Kayla’s holes.”

After a bit it didn’t seem like any more was coming out.

“Can we go back inside now? My butt’s getting cold,” Kayla complained.

Kieran nodded and Kayla quickly stood, pulling up her shorts and underwear as she did. The two cubs headed back over to the camper and quietly crawled back into their top bunk. They snuggled down to go to sleep, with Kieran spooning Kayla from behind. He put his arm around her.

“Sorry again for...what happened,” he whispered in her ear.

“It’s okay – it was an accident,” Kayla responded in kind. “But...you owe me.”

Kieran smiled. “Deal.”

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

The following morning the sun started peeking through the trees at around 6:30 AM. The sleeping cubs were only barely aware of their parents waking and exiting the camper. They slept for another hour or so, with Kayla being the first to wake up.

She stretched in place and yawned, rubbing her eyes with the back of her paws. Kieran had rolled away sometime during the night and was now facing away from her. She smiled as she looked over at him; she was surprised by herself and the fact that she wasn’t still mad at him for last night. Even though it hadn’t felt very good, it was still...interesting. Not to mention, it was still something naughty with Kieran, which always made her happy.

As if realizing he was being watched, Kieran’s eyes fluttered open. He tiredly looked to Kayla who was staring at him.

“What?” he asked groggily, still trying to blink the sleep out of his eyes.

Kayla shook her head. “Nothing.”

“...Kay?” Kieran replied, confused.

“You think mom and dad heard us last night?” Kayla asked, looking out the curtains of the small window by the top bunk, peering at her parents who were sitting out by the fire. She had propped herself up on her elbows. Her tank top hung loosely from her body, giving Kieran a peek down at her flat chest.

“No, I don’t think so. If they did...we’d probably be dead,” Kieran answered. “C’mon, let’s go.”

The pair crawled out of bed and climbed down the ladder. Kieran unzipped his dufflebag, which was sitting on the floor and pulled out a new t-shirt. He threw it over his head and started digging for some pants. Kayla was just sitting on their parent’s lower bunk, watching him.

“Heh,” Kieran chuckled softly.

“What?” Kayla asked, curious.

“It’s just – mom always makes me wait outside while you guys get ready for bed, but I’ve seen you completely naked before. And right now you’re just sitting there watching me,” Kieran explained. “It’s just funny.”

Kayla shrugged and Kieran shrugged back, pulling on his pants. The cubs left the camper and plopped down in folding chairs next to their parents.

“Morning guys!” Their mother greeted them warmly as they sat down. Her cubs grumbled back their responses while idly staring into the flickering flames of the campfire.

A thin mist floated on top of the lake, accentuating the cool morning. It slowly rolled across the water, disappearing when it got close to the shoreline. Kayla shivered.

“Aren’t you cold in those clothes?” Kayla’s father asked, a hint of disapproval in his voice.

Kayla shook her head. “No – I’m fine.”

Her dad just rolled his eyes and took another sip of his coffee.

“So what are you guys going to do today?” their mother broke in, changing the topic.

“I was thinking we’d take the boat out,” Kieran responded before adding, “If...that’s okay with you guys?”

He glanced over his father who gave a single nod. “Yeah, that should be fine. Just wear life jackets.”

The family had a small breakfast of granola bars around the campfire and waited for the sun to fully rise. The temperature quickly rose once the sun was out and dissipated the morning chill, the mist above the water clearing.

Kieran and his father carried the canoe over to water’s edge and Kayla carried over the life jackets. After setting them down in the boat she ran into the camper to change. She emerged a minute later wearing the bright yellow two-piece swimsuit she had bought just the other day. Kieran changed after her, putting on a pair of swim trunks and removing his shirt.

The bunny cubs headed over to the canoe and donned their life jackets. Kayla climbed inside, taking the front seat, as usual. Their mother called out after them: “Don’t stay out too long, okay?”

“Okay!” they replied in unison.

Kieran waded into the water and pulled the boat out behind him. He stopped when he was about knee-deep and climbed up into the canoe as it slowly drifted by. The boat rocked as he entered and he took his seat at the back. He looked back and gave one final wave to their parents before picking up his paddle and guiding them out further.

Kayla picked up her oar and joined in shortly after and they paddled out towards the middle of the lake. The would occasionally both paddle extremely hard, trying to get the boat to go as fast as they could. It was a little competition they’d have with themselves to try to see if they could beat their previous record.

Tired from their intense paddling, the two rabbits stopped to rest, letting the boat drift as it lost its momentum. Kayla spun around in her seat so she was facing backwards, towards Kieran.

“Whatcha wanna do now?” she asked, her heart pounding from exertion.

Kieran laid his paddle down in the bottom of the canoe. “Well,” he started, taking a slight pause, “I do have an idea...but you’re probably too chicken.”

Kayla glared at him and slapped her paddle against the water, splashing Kieran. “Am not!” she called out defending herself.

Kieran laughed and rubbed his face off with the back of his arm. “I dunno…” He was doing his best to rile her up and it was working perfectly. She just glared at him in silence.

“Alright, fine,” Kieran said, giving into Kayla’s pouting. “Well, I was thinking...I could do something for you, right here in the boat.”

“Right here?” Kayla asked.

Kieran nodded. “Yup. Right here.”

“Well, like...what would we do?”

“Nope, it’s a secret. You’re either in or you’re out.”

Kayla pondered this and scanned the rest of the lake for other boats. There was a powerboat way out on the other side of the lake, but nobody near Kieran and herself – perhaps it was still to early. She looked back towards their campsite; it was quite far. Their parents were just small specks at this distance. In fact, she couldn’t even tell if they were sitting or standing.

Sensing her trepidation, Kieran added, “Don’t worry – I don’t think anyone will be able to see us.”

“Okay,” Kayla agreed reluctantly, giving a single nod. She didn’t want to be seen as a chicken. Not to mention she was extremely curious what exactly her brother had in mind.

“’Kay, set down your paddle.”

Kayla did as her brother asked, laying her paddle down in the bottom of the canoe in front of her. She sat there cutely, gripping the bench she was seated on, looking expectantly at her older brother. Kieran got up from his seat and very carefully maneuvered his way over to Kayla, staying low in the boat so it wouldn’t capsize. He moved their paddles out of the way so he could kneel in front of Kayla.

The teenage rabbit looked up at his little sister and smiled. She returned the look as Kieran leaned forward and kissed her square on the lips. Kayla’s eyes opened wide at first, surprised by the sudden kiss. But it didn’t take long for her to melt into it, closing her eyes and kissing him back. The two kissed more and more passionately, Kieran’s tongue grazing Kayla’s lips, asking for permission. Kayla obliged, her lips parting as her brother’s tongue slipped into her mouth, greeting her own tongue as they made out in the canoe. Their bulky life jackets pressed against each other, making it hard to stay close.

They could each hear the others’ soft breathing through their pink noses with their faces so close together. The sound was accented only by that of water gently rippling against the boat and the occasional caw from a passing bird. Finally, Kieran broke the kiss and pulled away. It was clear Kayla hadn’t been ready for him to stop, her lips still slightly parted.

“Was...that my payback?” Kayla asked innocently, hoping that wasn’t all there was to it.

To her delight, Kieran shook his head and grinned. “Just the warm up.”

He reached out and grabbed the sides of Kayla’s bikini and started to tug on it. Kayla lifted her butt off the seat, allowing Kieran to continue pulling down her yellow swimsuit bottoms. He slid them down her slender legs, with Kayla helping by lifting her feet as he neared them, allowing him to slip them off completely.

Kieran admired the sight of Kayla sitting completely bottomless in front of him. Her knees were together, allowing just a small hint of her slit to barely peek out from between her thighs. Her pristine white fur was bare, all the way from her belly button to her fluffy feet, uncovered from any garments or shoes. It was a view that Kieran had rarely gotten to see, though that was becoming less and less true with each passing day; but seeing her naked body, or half-naked in this case, still excited him in ways he could hardly describe. 

Perhaps it was the fact that most people only got to see the “public Kayla” – the version that was dressed and from all outward appearances, a typical, innocent fifth grader. While on the other paw, Kieran got to see the “private Kayla” – including all of her body’s most intimate anatomy, along with her raw, unfiltered sexual urges. Urges and desires that one would never suspect of a cub her age. In fact, her body had experienced pleasures and sensations that most people would have assumed were impossible for someone her age; but Kieran knew better. He knew that despite being “just a cub,” Kayla was still very much a sexual being; she could experience a sexual climax just like any female could. Her young body was fully capable of both giving and receiving pleasure despite its small size.

Kieran shook his head slightly, knocking himself from his daze of arousing thoughts. He looked back at Kayla; her legs had relaxed slightly – her slit and buttcrack seemed to form a single, continuous line that divided her crotch. Kieran took each of her feet, one at a time, and draped her legs over the sides of the canoe, spreading her legs apart in the process. As they spread, Kayla’s pink, clitoral hood peeked out from between the top of her pussy lips. A small gap opened towards the bottom of her labia, just barely revealing the hole inside.

Kayla blushed looking down at Kieran; the rather compromising position put her privates on full display for him. She could feel his eyes roaming her body, taking in her every little detail. The soft, pink pads on the bottoms of Kayla’s feet grazed the water as her legs dangled over the sides of the boat. She waited eagerly in anticipation of what Kieran had in store for her.

Without another moment’s hesitation, Kieran moved his head in and pressed his lips against Kayla’s vulva, locking his mouth against her pussy. He immediately started licking and sucking with great fervor. Kayla drew in a sharp breath as a sudden, intense rush of pleasure shot out from her groin and down her legs. Her legs jerked, her feet splashing softly atop the still lake.

Kieran lapped with his tongue like a thirsty dog that had finally found water. The sound of wet slurping and sucking grew louder and louder. Kayla’s paws gripped the edges of the canoe tightly as she leaned back, her breathing heavy and unsteady. She moaned as more and more pleasure set her nerves alight; she wouldn’t last long at the rate Kieran was going.

With each successive lick, Kieran could swear he could feel Kayla’s little nub growing harder and harder. The heavenly musk emanating from Kayla’s pussy as she grew increasingly wetter, permeated Kieran’s nose furthering his own arousal; he could feel his erection straining against the netting of his swimsuit.

Kayla’s moans grew increasingly louder, but neither of the cubs cared. They were out on the water, far from anyone else and all that mattered was the moment. Kayla could feel the pressure building within herself – that desperate tension begging for release. The dulcet sound of her voice only further encouraged Kieran, his tongue flicking faster against her clit.

His tongue tiring, Kieran pulled his face away for a moment to rest. The fur around Kayla’s privates was soaked, along with Kieran’s cheeks – matted down by a combination of his own saliva and Kayla’s juices. Her pussy was swollen and red, and her clitoris had fully emerged from underneath its protective hood. Kayla’s pink inner lips, which were typically hidden by her puffy outer lips, had blossomed forth and darkened in color. Her sexual arousal was definitely at its peak.

“Don’t...stop,” Kayla begged quietly, peering down at Kieran, between her legs.

Hearing his little sister’s needy plea and seeing her young, cub-body in such a state of complete arousal was all the convincing Kieran needed. He greedily dug in, his tongue pressing and sliding against Kayla’s stiff clitoris. The presence of his tongue immediately drew a satisfied moan from the young bunny’s lips as she closed her eyes. Her breathing became even quicker, practically panting as her climax raced ever closer.

At last the flood gates crashed open violently; Kayla threw her head back and cried out in pleasure as a powerful orgasm began to rack her small body. The sound carried across the water, even managing to reach their parents before being mistaken for the sounds of playing. Her legs shot upwards on either side of Kieran, her toes pointing skyward as all the muscles in her lower body tightened. Her paws gripped the edges of the canoe even tighter, as if she was trying to hold on for dear life in a fierce storm of pleasure.

Kieran didn’t relent, instead giving a few more licks for good measure; he wanted to make absolutely sure she got the maximum enjoyment from this – after all, it was his reparation. He felt his tongue get wetter as Kayla’s contracting vagina pushed out her creamy girl-cum. The small hole pulsed as he forced his tongue inside, feeling her warm, soft flesh rippling around the tip of his tongue. He tasted his little sister’s salty-sweet nectar straight from the source as her young body pushed out more and more in ecstasy.

But for both of them it was over all too soon. Kayla relaxed her grip and lowered her legs slowly back down. Her feet drooped, tired from being tensed up, as her legs dangled over the sides of the boat, dipping her toes into the cool water. She was breathing heavily, her heart still racing, pounding hard enough that the beating was visible through her flat chest.

Kieran was also breathing quicker than normal. He pulled his head away and looked at the absolute mess he had made of his sister’s nethers. All of the fur around her pussy was completely damp. A small droplet of wetness trickled down from her slit, between the crevice of her cheeks, before clinging to the pink flesh of her tailhole.

“How’d that feel?” Kieran asked before licking his lips, getting another taste of Kayla’s saltiness. The intoxicating, girly aroma from her excitement that was still covering his face inundated his every breath, giving him a sort of aroused high. The smell was so distinctly Kayla – he had never smelled anything like it before they had started fooling around. It was her most intimate and private scent; it was that very, very few knew about.

“R-really good,” Kayla managed to finally stammer before hoisting herself back upright on the seat.

“Yeah?” Kieran asked in confirmation. “Does it make up for last night?”

Kayla blushed before finally nodding and admitting: “Yeah…”

“Good,” Kieran smiled, genuinely pleased that his little sister was happy with their bargain. He reached down and pick up her yellow bikini bottoms and tossed them to her. Kayla caught them and flipped them so they were no longer inside out. She lifted her feet and flung the legs holes over her toes, pulling the swimsuit up in the process. Her butt lifted from the seat momentarily as she finished pulling them into place.

“It wasn’t...that bad,” Kayla spoke softly, looking down at her feet.

“Huh? What wasn’t?”

“...Last night…,” Kayla admitted. “It wasn’t [i]all[/i] bad.” Her face turned beet red as she admitted getting at least some enjoyment from anal. Even Kieran blushed a little bit.

“Oh…” was all he could manage to say, being caught off-guard by Kayla’s comment.

For the first time, one of the cubs looked around as Kieran turned his head to either side to take in their surroundings. They had drifted a bit closer to the western shore. The shoreline wasn’t beach like everywhere else; it was covered with dense brush and forest that almost seemed to merge with the water. His eyes darted along the trees, stopping when they noticed something interesting. He quickly reached down and picked up his oar and started to paddle them towards it.

“Where are we going?” Kayla asked, turning to look over her shoulder in the direction they were traveling.

“I see something,” Kieran answered, continuing to paddle, focused on his target.

Kayla squinted her eyes and held her paw above her brow to block the sun. She tried to see what her brother was so interested in, but all she could see was a bunch of trees.

As they slid across the water, Kayla finally saw what Kieran did: a small opening towards the base of some thick brush at the water’s edge. It looked like the water continued underneath the brush and disappeared into the forest. She spun around in her seat and reached behind her to pick up her paddle. She started paddling in sync with her brother, getting them closer to their destination even quicker.

“I’ve heard about a secret lagoon,” Kieran said aloud as if answering a question Kayla hadn’t yet asked. “I’ve never been able to find it in all the years we’ve been coming here though.”

“You think it’s back there?”

“Yeah. Maybe.”

The two rabbit cubs paddled until their canoe finally came within feet of the dense brush. They slowed their pace and carefully guided the canoe into the small opening. Kayla ducked as the bow entered, then Kieran with the stern. They paddled awkwardly from their crouched positions as their boat crept up a small inlet. A natural tunnel of trees, bushes, and sticks surrounded them, blocking out most of the sunlight. After about 30 meters they could finally see the light at the end of the tunnel.

Their canoe emerged out the other side into a small lagoon. Sunlight pierced the shallow water, illuminating that it was only a few feet deep. Thick forest surround the protected cove on all sides and a small sandy beach lay to the south.

Kieran and Kayla paddled over and beached the boat. After the bow had ridden up onto the sand, Kieran hopped out over the side and pulled Kayla and the canoe ashore.

Kayla set down her paddle and climbed out, stretching once she was on dry land. Her toes gripped the sand as she straightened one arm above her head, grabbing it with her other paw behind her back.

“This place is awesome!” Kayla announced, her voice echoing against the trees.

“Yeah. I can’t believe we found it!”

Kieran unbuckled his life jacked and tossed it into the boat, with Kayla following his lead shortly thereafter. She walked around the small beach. “You think we’re the first ones to find this?” she asked cheerily.

“Nah. I doubt it.” He plopped down in the sand and laid back, folding his arms behind his head for support. The sun was bright in his face, so he closed his eyes and relaxed. The muscles in his tongue and neck were sore from eating Kayla out. He moved his mouth around, trying to find a way to relieve the pain. Eventually, he decided it felt best when he did nothing so he relaxed his jaw.

“Don’t tell me you’re tired!?” Kayla demanded, her paws on her hips, looking down at her brother, her body partially blocking the bright sun.

“Give me a break,” he shot back, not bothering to open his eyes. “Making you come was tiring.”

“Hmph.” Kayla crossed her arms over her chest and slumped her shoulders. “Well, it’s your own fault!”

Keiran swatted her away with a flick of his paw. “Just go play in the sand or something. I’m just going to rest here for a bit.”

“Fine.” Kayla kicked her foot into the sand, sending a blast of it across Kieran’s bare chest. She stomped off a few feet and sat down on the beach, her legs splayed out to either side, her feet behind her.

Kieran brushed away the sand, not letting it bother him, and drifted off to sleep.

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

When he awoke, he noticed that the sun had barely moved in the sky. “Guess I wasn’t asleep too long,” he thought to himself, somewhat relieved. He turned his head to his left – the direction that Kayla had stomped off in. He had to blink twice to make sure he wasn’t hallucinating.

Kayla was about ten feet away, on all fours, her bare bottom pointed in his direction. Her fluffy tail was up in the air and she was idly playing – digging in the sand, humming quietly to herself.

“What the...?” Kieran’s eyes darted from his sister’s naked backside to her discarded swimsuit laying atop the sand nearby. “Is she...naked!?” he asked himself, still in disbelief. He looked back to Kayla; her round, white butt and thighs framing her perfect pussy lips. The tops of her feet rested against the sand, exposing the soft, pink pads on their bottoms. With her short tail flagged, even her tight, pink tailhole was exposed.

Kieran’s cock quickly became hard, straining against his swimtrunks. He wasn’t sure if he imagined it or not, but he caught of whiff of Kayla’s female musk; whether it was coming from her pussy or his own, stained face – he didn’t know. His cock bounced against his belly, begging to come out. Here was a young, female rabbit, presenting to him, the aroma of her excitement in the air. It awakened something primal and instinctual within himself as a male: the need to breed.

He stood silently and pulled down his swimsuit, stepping out of it after it landed on the sand. Closing the distance between them with just a few steps, Kieran dropped down to his paws and knees and mounted Kayla from behind. The young bunny cub wasn’t even aware that Kieran was awake until he was already on top of her. Kieran stopped before actually penetrating her. His breath was heavy in her ears as he held himself above her. She had stopped constructing the sand castle she had been making and didn’t move.

After a few seconds of nothing happening, it was Kayla who acted first. She arched her back upwards, rubbing it against Kieran’s abdomen and chest. Her fluffy tail tickled his belly softly as she moved against him.

“Well…,” Kayla spoke softly, “Aren’t you going to put it in?”

The words coming into his ears, the voice sweet and cute, sent a shiver down Kieran’s spine. “Y-yeah,” Kieran responded, his voice breathy and full of need. He looked down. His paws were planted in the sand on either side of Kayla’s. The teenage rabbit lowered his hips and slowly rocked them, trying to maneuver himself into position.

He felt his tip press against Kayla’s squishy vulva and the heat coming off of her lips. He carefully rocked his hips again, keeping himself pressed against her. His tip slid up her slit, which was still very slick with her natural lubrication, before catching on her opening. Kieran pressed forward and the head of his penis spread Kayla’s hole before easily slipping inside.

The young bunny cub underneath him let out a soft moan as her big brother slid into her. Even Kieran grunted in pleasure as the warm, wet flesh of his little sister’s vagina wrapped tightly around his cock. He continued to push forward until finally his hips pressed firmly against her ass. Kayla bit her lip as her brother filled her completely; the satisfying feeling of “fullness” almost making her shiver.

Neither of them did anything for a second. They soaked in the feeling of their intimacy, listening to the quiet sounds of nature in their private lagoon that was only for them. Surrounded on all sides by dense forest, their privacy was assured – even if, on the beach, they felt completely exposed.

Kayla muttered something but Kieran didn’t catch what she said.

“Hm?” he asked, the question more a sound than an actual word.

“...F-fuck me,” Kayla repeated, louder this time. Her words were dripping with lust.

Kieran’s heart skipped a beat and he swallowed loudly. He had heard Kayla use the “f-word” maybe three times total in her life – and never in that context. Only something she shouted accidentally when getting hurt or when she thought she was in private with her friends. But hearing those words, in this context, uttered in his little sister’s normally-innocent voice, was more than Kieran could resist.

As if they had a mind of their own, his hips slammed into Kayla and started to thrust wildly. She let out a satisfied moan, her wish granted. Kieran’s cock was easily able to glide in and out of her tight hole, thanks to how wet she was.

“Fuck...if she’s this horny now...what’s going to happen when she gets her first heat?” Kieran pondered. “Or...maybe she’s in heat [i]now[/i]?” He shook his head and pushed the thoughts away. Maintaining a conscious stream of thought on anything but the pleasure was nearly impossible; besides,  he had decided he didn’t care. All that mattered was the feeling.

Kieran bucked against his little sister aggressively, bumping her body forward with every thrust. Kayla’s moans echoed in the small lagoon as the pair gave in to their baser instincts. Something about the fact that they were outdoors, completely nude, and going at it like proper bunnies – appealed to their raw animal instincts. It made it feel as though they were truly wild beasts, happening upon each other in mother nature, feverishly mating in an effort to further propagate their species. Even if their coupling could produce no offspring due to Kayla’s age, both of their bodies were hardwired to still try as hard as they could.

The sound of Kieran’s powerful hips slapping against Kayla’s ass filled the air as he picked up his pace. He fucked her with a ferocity and speed that could only be called completely appropriate for their species. This caused Kayla’s ears to bounce wildly and made her let out a small moan each time Kieran slammed into her. A squishing sound emanated from between Kayla’s legs as Kieran’s cock pummeled her very wet pussy. To anyone within earshot, it would have been perfectly clear what was going on – even if they were unable to see.

Kieran’s toes gripped into the sand as he pounded into his little sister. He wrapped his arms under her bare chest, bringing his own chest closer to her back as his hips continued to buck. He wanted more. He [i]needed[/i] more. His body demanded satisfaction and he was going to extract it from the bunny cub underneath him, no matter what.

Their climaxes were both rapidly approaching; heavy panting joined the chorus of obscene sounds filling the otherwise calm sanctuary. Kieran’s hips moved with blinding speed as he pushed himself past the point of no return. He held out for as long as he could and with one final thrust, buried himself all the way inside Kayla. Kieran let out a grunting moan as his cock pulsed; powerful jets of cum shot from his tip in rapid succession, firing against the back of Kayla’s vagina.

Feeling her brother’s throbbing member inside of her, Kayla’s own orgasm rippled off of Kieran’s. Her pussy clamped down around her brother’s cumming cock. The young bunny cub bit her lower lip, moaning into her mouth. Kieran gave a few final, jerky thrusts during Kayla’s climax, coaxing out a couple more bursts of cum from his cock.

Together, the cubs started to come down from their highs. However, neither of them moved for a full minute. Their breathing was heavy and steady. They were both too tired to move – their bodies telling them to stay just as they were.

After some time, Kieran finally dismounted, rolling off too the side. Kayla stood up and turned around to face her brother. She spread her legs apart and pulled at her vulva with her paws, spreading herself as she tried to see her own privates. After a few seconds, several globs of Kieran’s cum dripped from Kayla’s slit, falling between her slender legs before landing on the sand and partially soaking in.

“So that stuff is what would make me have a baby?” Kayla asked rather naively.

“Y-yeah,” Kieran answered, a little surprised. Sometimes, he forgot just how little she knew about everything. He watched a few more drops of his semen fall from Kayla’s lips. “But...you won’t,” he added, trying to preemptively calm any fears – or perhaps just his own. “You’re still too young.”

“Ah…” Kayla acknowledged.

“Why were you naked anyway?” he finally asked, remembering what started all this.

“Well...it was really wet down there,” Kayla spoke, turning a little red. “My fur...so I took off my swimsuit so it could dry out.”

Kieran shot her a skeptical look. “But, why would you take your top off too?”

Kayla shrugged, blushing even more. She of course knew why – she [i]wanted[/i] to have sex with Kieran and it was her way of showing that. But she was far too embarrassed to admit it. Just then she recalled what she had said to Kieran when he first mounted her. Her face and ears turned an even darker shade of red as her paws shot up to cover her face. She spun around so she wouldn’t have to face him.

Seeing her overwhelming embarrassment, Kieran decided to let her have a pass this time, instead of pursuing it any further. After all, he was sure that for her to admit the real reason would mean for her to admit defeat. He stood up, grabbing his swimtrunks in the process and throwing them on.

“C’mon, we should get back.”

Kayla turned back around having collected herself a little. “But…” Just then her stomach growled loudly, her body putting forth a different demand this time. She held her paws over her stomach as if trying to quite the grumbling.

“See, it’s time for lunch,” Kieran remarked with a smile.

“’Kay,” Kayla agreed, reaching down to pick up her discarded swimsuit. As she put it back on, Kieran walked over to the boat and took out their life jackets. He donned his own before tossing Kayla hers. Once she was dressed again, she put on her flotation device and climbed into the canoe, waiting for Kieran to push them out.

As he bent down to push the bow into the water, something shiny in the sand caught his eye. He stopped and bent down further to examine it. 

Buried in the sand was an old beer can, crushed and discarded. It looked like it was probably several months old, at least.

“See, I knew we weren’t the first ones here,” he remarked to Kayla, pulling the can out of the sand and holding it up for her to see. 

There was something else in the sand, next to where the can had been. He only realized it now that the can had partially uncovered it. He picked it up.

It took him a second to realize what he was holding, after all, he had never actually [i]seen[/i] a condom wrapper before. There were two of them attached to each other, a perforation in the package separating the two. One of the wrappers was torn open, its contents missing – but the other was still intact. Kieran rubbed the unopened side between his fingers and could feel the ring of the condom sliding around.

“Huh...guess we weren’t the first ones to do it here either…”

He held up the condom wrappers.

“What’s that?” Kayla squinted, trying to get a better look at what her brother was holding, but even then she didn’t recognize it.

“A condom,” Kieran answered, tearing the used package off of the sealed one and discarding it. “It keeps the girl from getting pregnant.”

“How?”

“I’ll show you sometime,” he answered with a knowing grin.

He stuffed the unopened condom into the pocket on his swim shorts and pushed the boat out. They navigated their way back out under the mess of trees and before long they were back out on the lake. They rowed towards camp, hopping ashore when they finally arrived. Their parents were sitting at the wooden picnic table nearby, already eating lunch. It looked like they had only just started.

“Oh good, you’re back!” called out their mother, waving them over. “I made us all peanut butter and jelly sandwiches!” She patted the bench next to her, offering the spot to Kayla who was already bounding over, her hunger seeming to drive her feet forward.

“Oh boy!” Kayla yelled out excitedly, plopping down next to her mother.

Once they were all seated and munching away on their PB & Js, the cubs’ mother asked, “So? Did you guys have fun? You were out a long time!”

Kieran and Kayla looked at each other with a knowing smile before Kayla answered innocently, “Oh yeah! We had a blast!”

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

Kieran awoke first to the sounds of birds chirping in the trees outside the camper. He lifted his head from the pillow and peered out through the window. His parents were sitting outside by the fire, silently nursing their steaming coffee cups. The sun was only just rising, a soft blue hue illuminating the campsite and filtering into the camper.

He looked over at Kayla who was still asleep on her stomach beside him. She had opted to take the spot closest to the ladder last night. Her long, floppy ears lay relaxed atop her pillow and her steady breathing was visible as a slight rise and fall of the blanket that was covering her. Kieran could hear the air softly passing through her little pink nose as she slept.

A slight smile crossed his lips and his heart beat a little faster than normal.

“She’s so cute…” he thought to himself, admiring her sleeping form.

Kieran brought his paw to her back, feeling the warmth of her body through her shirt. It had been quite a bit cooler last night, so Kayla had opted for warmer pajamas; a tie-dye t-shirt replaced her usual tank top and fuzzy, light blue pajama pants, covered with cartoon pigs flying amongst clouds replaced her usual black shorts. He rubbed her back gently, eliciting a soft, subtle noise of happiness from the sleeping bunny cub.

However, it didn’t take long for his teenage mind to crawl somewhere dirtier. He slid is paw down her back and squeezed her butt through her pajamas. After a couple of soft squeezes, he caressed her fluffy tail, feeling it tickle his paw. Touching another rabbit’s tail was a fairly intimate act, given its proximity to their body. Kieran and Kayla might have yanked on each others tails as very young cubs, rough housing and playing tag – but this was different. He had never really taken the time to appreciate the uniqueness of his little sister’s tail.

He slipped his fingers underneath the waistband of her pajamas, being sure to get underneath the hem of her panties too. His paw roamed down her butt, following her crack down between her legs. Kieran extended his middle finger, pressing it against her labia. He wiggled it back and forth, feeling her soft lips squish underneath the tip of his finger.

Kayla let out another noise, but this time, there was a definite hint of pleasure to her moan. He wiggled his finger back and forth more, gradually feeling the tender flesh below become slicker and slicker. Kayla’s breathing became more noticable, but she still appeared to be asleep. Kieran curled his finger inward, slipping it between her lips and finding her entrance. He slowly pushed inside of her, feeling her walls wrap snugly around his finger.

“Mmm…” Kayla moaned, her eyes still closed.

Kieran thrust his finger in and out of his little sister, keeping his paw held in place. “You like it when I finger your pussy?” Kieran asked rhetorically, more for his own benefit.

“Y...yeah,” Kayla replied, her voice quiet and shy.

Kieran froze, startled by her response, his finger still partially inside of her.

“K-Kayla...s-sorry, I…”

“S’okay,” Kayla replied happily, still sounding a bit sleepy. “I was having a good dream...now I know why.” Her eyes were still closed, her head resting atop her pillow.

“Oh?”

“Yeah...Kieran, don’t stop……”

Kayla begged her older brother. She thrust her hips back, forcing more of Kieran’s finger back inside of her.

“Kayla…”

“Hm?” She was gently rocking her hips, fucking herself with his finger as his paw remained in her pants.

“You wanna do it for real?”

That got her attention. 

She stopped moving and finally opened her eyes. Lifting her head, she looked out the camper window and saw their parents sitting in the folding chairs.

“What about mom and dad?”

“You know how they are in the mornings...probably not even fully awake yet. Besides, we’ll be quiet and stay under the blanket. Plus, we’d see them coming over here.”

“’Kay…” Kayla agreed, her heart pounding with excitement.

Kieran withdrew his paw and got all the way under the blanket. He grasped the hem of her pajamas and tugged them down, dragging her underwear along with them, until they were around her ankles. Next, he pulled down his own boxer shorts, freeing his already-stiff cock. He crawled back out from the under the blanket, letting it drape over his back. With the blanket sufficiently covering both of them, he climbed on top of Kayla.

“NOT...in my butt this time,” Kayla clarified, tossing a playful glare up at Kieran.

“Don’t worry, I won’t. Promise.”

He gave her a reassuring smile before taking his member in his paw. Kieran guided himself towards her slit and felt her slippery lips slide against his tip. He slowly pushed forward, feeling her spread open for him as he entered.

Kayla let out a vocal moan as Kieran pressed into her. She gripped the upper edge of the bunk in her paws and closed her eyes, her chin on the pillow. The teenage bunny started to steadily thrust in and out of his little sister. She felt especially tight, given the closed position of her legs. The bed creaked quietly under Kieran’s movements, joining the sound of Kayla’s heavy breathing and the soft tweeting of early morning birds.

Kieran’s hips jerked as he thrust into her more vigorously. His thighs slapped softly against Kayla’s plump cheeks. For a second, Kieran worried that they might be rocking the camper, but this was quickly replaced by a different worry as Kayla let out another moan, louder this time. He froze, stopping mid-thrust and peering out the window.

The cubs’ mother briefly glanced over at the camper for a few agonizing seconds, but then returned to idly staring at the fire.

“Shh~!” Kieran urged. “You gotta be quiet!”

“S-sorry, I’m trying but…it just, feels so good.”

“I know…” Kieran admitted, steadily resuming his thrusting, gentler this time. He couldn’t risk his mom hearing a second time. Once and she could brush it off as her imagination, but any more than that and she’d probably get suspicious.

Kayla’s walls gripped Kieran’s cock warmly as it slid in and out of her. Feeling the urge to moan, Kayla buried her face in her pillow this time. Kieran pressed his hips against hers and rocked them, causing his member to enter her at a different angle, grinding against her g-spot. The sudden intense pummeling of one of her most sensitive areas made Kayla moan – the sound muffled by her pillow this time.

“Yeah!” Kayla cried out through gritted teeth, her face still buried. “There, Kieran!”

Hearing the words, Kieran redoubled his efforts, keeping his hips firmly pressed against her ass and rocking his hips harder. The head of his cock slid firmly back and forth repeatedly against the rough spot on the front of her vagina, quickly pushing Kayla over the edge. She clenched her legs and her pussy clamped down around Kieran’s cock. She moaned into her pillow as she came, hard.

“Oh fuck~!” Kieran called out softly, surprised by the sudden intense pleasure from Kayla’s vice-like grip on his penis, setting off his own climax. His cock throbbed as pulses of cum erupted from his tip, firing deep inside of Kayla. He laid his head down on Kayla’s pillow next to hers, collapsing on top of her.

Suddenly, not two seconds later, the door of the camper opened. The spring creaked loudly as the door swung open. Both of the cubs felt their hearts leap into their throats, their dual climaxes still not yet quite finished.

“What are you guys doing?” their mother asked, still standing in the doorway.

“Wrestling,” Kieran replied hastily, his voice creaking as one final burst of cum erupted from his cock. 
It was the best answer he could come up with quickly. He just hoped it’d be enough to convince her.

Their mother raised her eyebrow suspiciously. “Seems a little early for picking on your sister...But, come on, time to get up. We’re heading out soon.”

Nothing but a blanket stood between what appeared to be simple sibling rough housing and the reality that both of her cubs were naked from the waist down, engaged in an act of raw incest. If only she had x-ray vision, she could have realized that her son’s cock was, in fact, buried firmly inside her daughter, a pool of his cum at sitting at the back of her vagina.

A few final drops of semen still leaked from Kieran’s tip, dribbling inside of Kayla. The cubs didn’t dare move.

“Kieran! Get off of me!” Kayla said, faking an annoyed tone rather convincingly. She had caught on quick and was playing along with her brother’s ruse.

“Not until you say you’re sorry!” he shot back, playing right along with her. He knew of course that getting off of her presently was out of the question.

Their mother rolled her eyes and spun around, leaving the camper and heading back over to the fire.

“Holy shit that was so close!” Kieran said as soon as she was gone. He quickly rolled off of his sister, his cock sliding out of her and pulled up his boxers. Kayla too scrambled to get dressed, yanking up her underwear and pajamas quickly enough that none of Kieran’s cum had a chance to leak out of her. She threw off the covers and climbed down the ladder.

“Yeah, [i]really[/i] close,” Kayla finally agreed, her heart still pounding. 

“Awww maaan~!” she cried out as she reached the floor, seemingly out of nowhere.

“What?”

“Your [i]stuff[/i] is...in my underwear now. It’s all slimey.”

Now that she was standing, Kayla could feel her brother’s cum sliding down out of her, collecting in the crotch of her panties.

“Sorry…” Kieran replied, giving her a half-smile from the top bunk.

Kayla shrugged. “S’okay. I’ll just change them...but, should probably wait until you’re outside the camper...just in case.”

“Agreed.”

Kieran descended the ladder and threw on pants and a t-shirt before stepping outside and heading over to the fire. As soon as the door closed, Kayla quickly pulled down her pajama bottoms and removed her now cum-stained pink and blue panties. She wadded them up and shoved them deep in her bag. She dug around and found another clean pair and hastily threw them on before pulling her PJs back on.

Within no time she was out sitting by the fire with the rest of the family, her parents blissfully unaware of what exactly their cubs had been up to this morning. Or the rest of the trip for that matter. After a light breakfast, the four of them packed up camp and loaded into the minivan, heading back towards the city and their home.

Somewhere along the way the cubs’ mother called back to them. “So, did you guys have fun this trip?”

“Oh yeah!” Kayla shouted.

“Definitely!” Kieran decreed.

“Good.” And with a loving, naive smile their mother turned back around and buried her head in her e-book.

The cubs turned to look at each other, both of them smiling big, their faces slightly pink. One thing was for certain: it was definitely the most memorable trip to the lake they had ever taken.
