Kieran wiped his brow with the back of his paw as he rested against the old, rusty push mower. He looked over at the garage, seeing his dad’s Porsche sitting there elegantly, then back down at the archaic yard tool he was propping himself up with.

He sighed.

“I don’t understand why we don’t just get a gas mower like every other normal family,” he griped, shaking his head.

The late morning sun was already sweltering and without a cloud in the sky, it seemed Kieran wouldn’t be getting a reprieve from the heat anytime soon. The teenage rabbit pushed the mower another few feet before stopping again. The effort required for even such a short distance was immense.

“Screw this! I need a drink.”

He pushed the mower over and let it fall where it sat and headed into the house. The air-conditioned atmosphere inside was a god-send for the hot bunny. He peeled off his shirt and flung it over his shoulder, exposing his athletic body to the cool, crisp air. Once inside the kitchen, he grabbed the handle and pulled open the fridge.

“Done already?” his mom called out from the other side of the fridge door. Kieran stood back up, pulling out a jug of iced tea as he did. He opened it.

“Not yet. Just taking a break.”

“Hey! Get a glass mister!” Kieran’s mom chided as he started to lift the jug to his lips.

Kieran rolled his eyes and reached into the open cabinet of dishes begrudgingly, pulling out a glass and pouring the tea into it. 

“I was gonna! I was just fakin’!” he retorted in typical teenage fashion.

“Uh huh,” his mother replied, fully aware of her son’s lie. As Kieran took a several big gulps of tea, she continued, “Actually, I’m glad you’re here... How close are you to finishing with the lawn?”

He paused briefly from drinking, wiping his mouth with the back of his paw. “I dunno, maybe like half?”

“Hm, okay...well – the lawn can wait. I actually need you to run to the store and pick up some groceries for the trip.”

The family of four was planning to take their tow-behind camper up to Lake Sumara that weekend to help beat the heat for the long holiday weekend.

Kieran lowered the now empty glass and set it on the counter. The gears were already turning in his head; anything sounded better than mowing the lawn. 

“But wait...isn’t dad going to be hooking up the camper to the mini-van? How am I supposed to get to the store?”

Evidently Kieran’s mother hadn’t thought of that. She considered the problem and hummed thoughtfully. Motioning for him to follow, she lead him out to the garage; Kieran’s father was busy organizing the things they’d be taking on the trip: the canoe, paddles, life jackets, etc.

“Henry?” Kieran’s mother called out to her husband. He stopped what he was doing and turned to face his wife and son.

“Hmm?” He was obviously annoyed at the interruption.

“I need Kieran to go to the store...can he take the Porsche? I know you need to hook up the camper to the van…” the teen’s mother posited.

Kieran’s father’s face grew even more serious. He knew that this was a battle he wasn’t going to win with his already frantic wife. She always got so flustered when it was time to pack and prepare for a trip; any disagreements were likely to set her off. She wasn’t asking as much as she was telling. With a heavy sigh he fished the keys out of his pocket, tossing them over to Kieran.

No sooner had he caught the keys that a big grin had already started to form on Kieran’s face. “Score!” he thought to himself.

As if [i]hearing[/i] his son’s thoughts, Kieran’s father spoke sternly, his voice gruff. “Keep it [i]AT[/i] or [i]BELOW[/i] the speed limit at [i]ALL[/i] times. No horsing around. Got it?”

Kieran could tell his father meant business, the look in his eyes alone was enough to send chills up and down his spine. He nodded sheepishly and swallowed, suddenly much more worried about the responsibility.

“There, that’s settled!” his mom said gleefully. She smiled and spun on her heel and walked back inside to the kitchen. Kieran followed. She picked up a list from the kitchen counter and handed it to her son. “I need everything on this list, okay?”

Kieran nodded.

“Oh, and...take your sister. She’ll just be getting in the way here.”

Kieran’s features fell and his shoulders slumped. “But [i]moooom[/i],” the teen rabbit protested. His dreams of cruising around in his dad’s Porsche, top down, radio blaring, nothing but him and the open road were quickly getting dashed.

“No buts! I need you to just do it, okay? To help out the family.”

That was always her favorite expression: “to help out the family.” It was like a silver bullet that nobody could compete against. After all, [i]nobody[/i] wanted to let down the family, least of all their mother.

Another nod from the subdued teenager. Kieran stuffed the note in his back pocket and stormed off to the living room where he could already hear the TV blaring.

On the couch was Kayla, Kieran’s little sister, laying upside down with her head on the floor and her legs running up the back of the couch. She was wearing her usual pajamas: a pair of black sport shorts and a white tank top. The precarious position caused her shorts to ride up, falling up her legs making the shorts seem even smaller than they already were. Kieran could swear he saw a glimpse of yellow just barely peeking out from beneath her shorts. However, he quickly averted his gaze and focused on her face. Her eyes were glued to the television where some stupid cartoon show with obnoxious voices was flashing across the screen.

“What are you doing?” he asked bluntly.

“Watching cartoons,” she replied nonchalantly, as if it was obvious.

“I see that, dork. Why are you upside down?”

Kayla shrugged, her eyes finally leaving the screen and focusing on her brother. “I ‘unno.”

“Well, get up and get dressed. Mom wants us to go to the store,” Kieran instructed.

“’Kay!”

Kayla happily hopped up and righted herself in a matter of seconds. She bounded off up the stairs to her room to get changed. Kieran rolled his eyes and picked up the remote off the couch and clicked off the set.

“Must I do [i]EVERYTHING[/i]?” he asked himself rhetorically.

After about a minute, Kayla was dressed in a pair of jean shorts and gray t-shirt, running back down the stairs, obviously excited about the errand they were being sent on. She did always like riding along with her big brother when he drove. Not to mention, the two had had some rather [i]interesting[/i] trips in the car lately.

Brother and sister headed out the front door and Kayla immediately ran over to the passenger door of the mini-van.

“Wrong one, dummy,” Kieran teased.

Kayla looked back at him, confused.

“We’re taking the Porsche,” he confirmed, a smirk on his face.

Kayla’s eyes opened wide with surprise and she immediately looked over at their dad. Did [i]HE[/i] know that they were taking the Porsche?

The cubs’ father was busying himself with cleaning out the cooler; he seemed just a little [i]too[/i] focused on the task at hand as he tried to block out the thoughts of his son taking his most prized possession to the store.

Kieran had already strolled over to the driver’s side door of the bright red sports car and was unlocking it. Kayla shrugged and ran over, gripping the passenger door handle in her paw and pulling it open. The tan leather interior was immaculate and still smelled new as the two cubs climbed into the car.

“Better not crash,” Kayla ribbed, sticking out her tongue at her older brother, knowing that he’d be dead if the car came back with so much as a scratch.

Kieran swallowed audibly again as he pushed the key into the ignition and turned over the engine, his little sister’s remark reigniting the fear within him. With a roar the car came to life and Kieran could feel the purr of the engine as it rumbled through his grip on the steering wheel. After adjusting the mirrors he put the car into reverse and carefully pulled out onto the street.

The novice driver was nervous at first, but soon felt more comfortable behind the wheel of the powerful car than he did the family mini-van. It was like he was connected with it somehow, able to feel all the curves and subtleties of the road as the headed into town.

After about fifteen minutes of very cautious and careful driving, the bunny siblings were pulling into the parking lot of the big box store. Kieran made sure to park way out in the lot, far away from any of the other vehicles, lest he wind up with a door ding or worse.

They entered the store and headed towards to the side housing all of the groceries, past the various makeup, clothing, and household items. However, a small, cub-sized mannequin sporting a two-piece bikini caught Kayla’s attention and she immediately bounded over to it.

“Ooh! Ooh!” she excitedly called out to Kieran, pointing at the mannequin. “Can I get a new swimsuit while we’re here!?”

Kieran pulled the list out of his pocket and examined it. “I dunno...this doesn’t say anything about a swimsuit.” He raised an eyebrow and gave his little sister a look.

“[i]Pleeeeaaaaase[/i],” Kayla begged. “I really need a new one! My old one is too small!”

Her older brother had flashes in his mind: mental images of Kayla strapped into a swimsuit that was too small for her, the tight fabric hugging her cub body immodestly. His eyes locked with his little sister’s; he could see the excitement behind them and he simply didn’t have the willpower to say no.

“Alright, fine. But nothing too expensive, okay? I don’t want mom to get mad.”

“YES!” Kayla jumped with joy and scampered off into the racks of girls swimsuits. Kieran followed reluctantly, feeling a bit awkward as a teenage guy in the girl’s clothing section. Kayla was already busy thumbing through the “9-11” section of the rack, quickly eyeing the different patterns and designs before either moving on or pulling a suit off the rack.

After collecting up a few swimsuits, Kayla held them each up in front of herself, examining them closer. She tried holding them against her body and imagining how she’d look, but her limited perspective as she looked down was not satisfactory. There didn’t seem to be any mirrors around either. She quirked her face in disappointment.

“I need a dressing room! Otherwise, how will I know which one I like?” she complained to Kieran.

Her older brother shrugged and looked around, spotting the “Fitting Rooms” sign in the middle of the clothing section. “Ah,” Kieran nodded in that direction, causing Kayla to look.

“Right!” she replied happily and hurried over to the changing rooms. There were three stalls, and they were only about 10 feet tall – a small portion of the overall height of the store, leaving them completely open at the top.

“Need to try those on sweetie?” the female gazelle clerk asked as Kayla approached.

“Mhmm,” Kayla affirmed, nodding.

“Right in here, hon.”

The clerk pulled out a set of keys and thumbed through until she found the one she needed. She opened one of the rooms up for Kayla and held the door open, allowing her to enter. Kieran smiled at the clerk as she pulled the door closed after Kayla had entered. The gazelle politely smiled back. He couldn’t help but feel a little awkward – hopefully the clerk could guess they were brother and sister and he wasn’t just some creeper.

There was an electronic buzz as the clerk’s walkie-talkie activated. “Diana? Can we get a clean up in make up?” the voice asked over the radio.

The clerk pulled the radio from her belt and lifted it, depressing the talk button: “Sure, I’ll be right over.” And with another polite smile she was speeding off out of the clothing section to another part of the store.

Kieran looked around and over his shoulder, verifying that nobody else was around. Satisfied, he approached Kayla’s changing room and rapped his knuckles against the door.

“Hey, open up, it’s me,” he whispered loud enough that she’d be able to hear through the wooden slats on the door.

“Kieran?” Kayla sounded confused.

She opened the door just a crack and peeked out, concealing herself behind the door. Kieran pushed his way into his little sister’s fitting room.

“Hey!” she objected, “What are you-!?”

Kieran ignored his little sister’s protests and closed the door behind him after slipping inside.

Kayla was already naked from the waist up. Her t-shirt lay piled up unceremoniously on the bench, leaving her bare chest and abdomen exposed. The young cub’s snow-white fur almost seemed to glow in the bright florescent lights of the store. Tiny pink nipples peeked out against the stark white, resting atop would could only very generously be called mounds. Kayla’s bellybutton sat in the middle of her lithe, athletic frame – her abdomen devoid of nearly any kind of body fat.

“Shhhh!” Kieran urged, not wanting to draw any attention or suspicion in case the clerk had returned. “I figured I could help you pick out a suit is all.”

“Liar. You just wanted to see me naked – you perv!”

Kieran smirked. He knew his little sister was no fool. However, he also knew she wasn’t seriously objecting to his presence either. He took a seat on the bench, crossing his arms across his chest as if impatient.

“Well?” he stated plainly, asking if she was going to continue.

Kayla blushed, her face flushing pink. Her cute, pink nose wiggled.

She used one foot to remove the shoe from the other and then repeated the motion so she was standing barefoot on the tile floor. 

Kayla paused and swallowed nervously. Only a little bit left. In one smooth motion she pulled down her jean shorts and underwear at the same time. The clothing fell around her feet and Kieran glanced down, noting that her panties were a pattern of white and yellow stripes – he [i]had[/i] seen a flash of yellow! She stepped out of them, kicking them aside and under the bench so they were out of the way.

Kayla now stood in front of Kieran, completely butt-naked, in the middle of a busy shopping center – granted, within the privacy of a changing room. Being open at the top, the small room allowed them to still hear to hustle and bustle of the store, making Kayla feeling much more vulnerable and exposed than she actually was.

Standing there naked, her small slit just barely peeked out from between her legs. She let her older brother admire, as embarrassing as it was. She would never have admitted it, but the whole situation was actually rather exciting. Arousing, even.

Kieran looked Kayla up and down, examining her nude, cub body. His eyes were particularly drawn to the small ‘Y’ shape of her crotch and the little line that divided her labia. He could already feel himself getting hard.

Kayla, starting to feel a little too embarrassed, turned around as to hide her full-frontal nudity from her big brother. However, this of course presented him with her firm, bare butt. Her fluffy white tail sat neatly above her crack. Her little bunny buns were perfectly round and supple; in fact, her entire anatomy was impeccable – as could be expected of a cub her age – before the onset of puberty or her first heat. Even her back was sexy; the indent of her spine running the full length of her torso and her shoulder blades, sticking out ever so slightly, somehow amplified just how naked she was.

“Ahem, shouldn’t we, uh… try on some suits?” Kieran asked, finally pulling himself out of the stupor that his little sister’s body cast upon him. He glanced in the mirror opposite of Kayla and noticed that she had been watching him gawk at her.

Kayla locked eyes with her brother in the mirror and nodded. Still facing away, she reached for the suits that were draped on their hangers, dangling from a post on the wall.

The first suit she grabbed was a lime green two-piece. The young bunny cub quickly removed the swimsuit bottoms from the plastic hanger and bent down, treating Kieran to a brief peek of her puffy pussy lips as they peeked out from between her thighs. She stepped through the leg holes and pulled them up around her waist. The young bunny cup pulled on the lime green top and adjusted it into position, covering her flat chest. She turned around and posed for Kieran, holding out her arms to the sides. 

“Tada!”

“What about the back?” Kieran asked, his motives only slightly devious.

Kayla spun around. The picture of a large slice of lime, placed squarely on his little sister’s butt made him start to crack up. “Bahahaha!” Embarrassed, she quickly spun back around to face him, a hurt expression growing on her face.

“What!? What’s so funny!?”

“Nothing, nothing. Just, look in the mirror. There’s a LIME on your BUTT!”

Kayla looked over her shoulder and positioned herself in the mirror so she could see her own backside.

“Oh,” she said, sounding a little disappointed. “I hadn’t seen that I guess.” She felt some relief though, knowing that it wasn’t [i]her[/i] that he was laughing at.

Kieran was still chuckling slightly as Kayla quickly stripped back out of the swimsuit and clumsily put it back on the hanger.

“Shut up!” she retorted, casting an angry glare in her brother’s direction. “I won’t get that one!”

Kieran ogled Kayla’s young naked body some more as she went to grab another suit. He was tenting his own shorts firmly with a massive erection. She was just so [i]HOT[/i] … and [i]CUTE[/i]! How could she be both at the same time!?

The next suit she grabbed was bright yellow. She double checked that there weren’t any lemons on the front or back before removing this one from the hanger. Again she pulled up on the bottoms, covering her nudity, much to Kieran’s disappointment. She put her arms through the straps of the top and turned her back to her big brother, backing towards him.

“Can...can you help tie me?”

“Sure,” Kieran replied affectionately, taking the strings in his paws and tying them in a simple knot, securing the swimsuit top in place.

She took a step away and again showed herself off to her big brother.

“Whaddya think?”

“I think it’s really sexy,” he answered, causing Kayla to blush and smile.

Kieran couldn’t wait any longer.

“Really?” she asked, as if she didn’t fully believe him, worried he might be teasing again.

Kieran simply nodded in response. “In fact…”

He motioned for her to come closer to him. Kayla did and was surprised when Kieran pulled her in, wrapping his arms around her. Without even a second thought or any kind of warning, he kissed her.

Kayla’s eyes shot open in surprise before slowly relaxing and closing as she melted into the kiss. She kissed him back, putting her own arms around his neck.

Kieran’s paws roamed down her mostly bare back, until they reached her ass. He took a pawful of her tender young cheeks in each of his paws, squeezing and kneading the flesh that was hidden away in the swimsuit. As their kiss continued, Kieran started to pull down Kayla’s bottoms from behind.

He had pulled them down about halfway, exposing the top half of her bare ass; it was then that Kayla realized where this was going. She quickly reached down, pulling them back up and finally breaking the kiss with Kieran, pushing herself away with her other paw and holding herself at arms length.

“Wait...Kieran…”

“Aww c’mon Kayla...I’m so fucking hard right now,” Kieran begged.

Kayla looked down at her big brother’s crotch, easily confirming his own admission. The little bunny cub blushed more, but she still frowned.

“Not here...Besides,” she explained, “I’m still kinda...sore.”

Kieran’s shoulders slumped and he frowned too. “Okay,” he acquiesced. He wasn’t going to force her to do anything she didn’t want to do after all – and he certainly didn’t want to hurt her. Even though that was how their little “games” had started, it had grown into something more. It wouldn’t be any fun if she wasn’t into it too. He let go of her and Kayla finished pulling the yellow bottoms back up over her backside and took a step back.

Kayla had turned toward the mirror and was examining herself in it, her brother’s words about the swimsuit being sexy echoing in her mind.

“What about a bj?” Kieran asked, somewhat quietly, yet still startling Kayla, breaking her out of her daze.

She spun back around and looked at him skeptically. “I dunno...I’m worried we’d get caught or something.”

“It’ll be fine. I promise! Nobody is going to catch us,” Kieran assured her in a calm, soothing tone. He gestured toward the closed changing room door.

However, Kayla still looked anxious and he could see the trepidation in her eyes. He had to think of something to sweeten the deal.

“What if I buy you any candy bar or soda or whatever you want from the front of the store?”

Immediately he could see Kayla working the offer over in her mind, trying to figure out if it was worth it and how she could maximize her benefit. Their parents usually didn’t keep soda around the house, and candy was certainly an exceptional treat and certainly something she wouldn’t normally spend her own allowance on. Her lips pursed as she thought over her big brother’s offer.

“Deal!” she said firmly, finally holding out her paw for him to shake.

Kieran smirked and took his little sister’s paw in his own and gave it a couple shakes. No sooner had her let go of her paw, he was standing up and unbuttoning his shorts. He dropped them, letting them fall around his feet. He shimmied his boxers down towards the floor as he quickly pulled them down, freeing his stiff cock from its prison of fabric.

Kayla’s eyes grew wide upon seeing her brother’s uncut member. She had seen it several times before, but each time it still amazed her. Kieran’s excitement was quite evident: a large drop of precome was already forming on his tip in anticipation. It continued to grow and grow until finally it started to slowly drip, dangling from his tip by a thin, clear string. Kayla just stared.

Kieran’s voice snapped her back to reality. “C’mon, hurry up! Before the clerk comes back!” he reminded her with some urgency.

“R-right!” Kayla acknowledged and gave a quick nod.

She got down on her knees, still wearing the yellow swimsuit that didn’t technically belong to her yet. Kieran watched as his little sister opened her mouth wide, sticking out her tongue as if to make more room for him, and gradually took his cock between her lips.

The first sensation he felt was the incredible warmth of her mouth as her lips closed around his member. Next up was the slick, wetness of her saliva as she started to suck on him, moving her head back and forth. Her tongue pressed against the bottom of his length as it slid back and forth over it.

Her anxiety started to vanish and her own confidence returned as she started to suck on him a little harder. Her movements grew quicker and smoother as she took as much of her brother’s length into her mouth as she could before almost completely removing him, all to just repeat the process once more. More and more of Kieran’s precome was now leaking freely into her mouth, but with all of her saliva and sucking, she couldn’t even tell.

Kieran looked over at the mirror, getting an amazing profile-view of his little sister, on her knees, her head bobbing back and forth as she sucked his cock in the changing room of the superstore. She lifted her arms, grabbing onto his thighs to steady herself and provide additional leverage. The sound of an occasional, audible suck would echo in the tiny room as the seal of her lips around his cock fought to stay closed.

Suddenly, there was a soft knock on the changing room door.

Kieran’s heart nearly stopped, his stomach lurching up into this throat. Kayla must not have heard it, as she was still sucking away at her big brother’s dick.

“Miss? Is everything okay in there?” the clerk from earlier asked from beyond the door.

Kayla, finally hearing the clerk, looked up at Kieran for advice on what to do. Funnily enough, she still had her mouth wrapped around his cock. Kieran made a face as if to say, “Are you serious!? ANSWER HER!”

Finally, she pulled Kieran’s cock out of her mouth and turned her head toward the door.

“Yeah, sorry. Everything’s fine! Just having a hard time deciding!”

“That’s alright sweetheart, take all the time you need! I’ll be around hanging clothes on the racks if you have any questions, okay?”

“Okay, thanks!”

The cubs listened to the sound of the gazelle’s footsteps retreating away from the changing rooms and they both felt a way of relief wash over them. Kieran sighed, his pulse only now starting to come down. However, the drop in heart rate would be short lived, as Kayla picked right back up where she left off.

Kieran was surprised by the sudden warmth as Kayla suddenly took him back into her mouth, wrapping her lips around his length and sucking. Her tongue slid along his shaft, traversing his full length while his tip pressed against the soft roof of her mouth. She was working hard – determined to get what she wanted. And it would soon pay off; Kieran was nearing his limit and he could feel it.

“Wait,” he managed to say, the words sounding strained as he combated the urge to simply have her continue. “Open your mouth.”

Kayla looked up at him confused, but did as he asked. She opened her mouth and looked up at him with innocent eyes, wondering why he had asked her to stop.

“And stick out your tongue a bit.”

Again, Kayla did as she was asked. Her tongue resting gently on her lower lip.

Kieran started to jerk himself off, using his little sister’s saliva that was still covering his cock as lube. His foreskin was fully retracted on his uncut cock, revealing the thick pink head of his penis. He worked himself closer and closer until he was [i]just[/i] teetering on the edge of climax. Finally, he pressed his tip against her tongue; the warm, soft, wetness pressing against his glans was all he needed.

He felt his cock throb in his paw as he started to ejaculate into the young bunny cub’s mouth. Kayla flinched as the first burst shot against her tongue, the hot fluid hitting the back of her throat. It was quickly followed by another, and another. Kieran watched as each jet of milky white cum erupted from the tip of his cock, grazing along Kayla’s tongue before ultimately pooling in the bottom of her mouth. Kayla just kept looking up into her big brother’s eyes as he achieved release, spilling his load into her open mouth. Her unwavering gaze just made the experience all the more arousing for Kieran – keeping the fact that this was indeed his little sister ever prescient in the front of his mind throughout his orgasm.

After only a short while, the teenage rabbit’s climax seemed to be subsiding; the powerful bursts had settled into mild dribbles – with a small amount still leaking from his now dark pink tip each time he pulsed. Still, Kayla remained still, her mouth agape, waiting for her brother to finish before doing anything. 

Finally, he pulled away. Kayla sat there, her mouth full of her big brother’s cum. The cloudy, alabaster seed pooled around her tongue. Kieran smirked, somewhat proud of the sight for whatever reason.

Satisfied that he was indeed finished, Kayla finally closed her mouth. She tilted her head back dramatically, and with one big, audible gulp, swallowed Kieran’s load. His viscous semen slid slowly down her throat. She could feel it’s warmth and sliminess, even as it continued on down towards her stomach.

Kieran’s eyes were wide with shock.

“You swallowed it!? [i]Again[/i]!?”

Kayla smiled and nodded. “Well, duh. What else was I going to do? Spit it on the floor?”

She asked him as though he was being a complete idiot about it. And as Kieran thought about it more, he realized she wasn’t completely wrong. It’s not as though there was really anything [i]else[/i] she could have done. It was the most logical way to dispose of it.

“Good point…” he acquiesced. 

Kayla happily beamed at the acknowledgment of her superiority – at least in that moment.

“Well then, with [i]that[/i] taken care of – I still have one more suit to try on!”

She eagerly hopped back up and stood before the mirror, somehow returning to their prior activity as if nothing had even happened. 

However, suddenly, she froze, making a small “eep!” noise as she did.

“Hm? What’s wrong?” Kieran questioned, pulling his shorts and underwear back up.

“N-nothing!” Kayla stammered. 

There was something wet between her legs.

She slowly started to pull down the yellow swimsuit bottoms. Kieran watched from behind, eager to catch yet another glimpse of his little sister’s naked body. His eyes quickly noticed something else though.

Just as Kayla had pulled the bottoms past her bare butt cheeks, Kieran caught a glimpse a very thin, clear strand of something stretching between the swimsuit and Kayla’s pussy. It took him a few seconds to process what it was.

Kayla was looking too, only from the front. 

She pulled the bottoms away from her legs so she could get a better view inside of them. Kayla’s expression became horrified and her face flushed a dark red as she realized what that wet feeling had been; the young bunny girl had left a rather impressive snail-trail of prepubescent female excitement coating the inner fabric of the yellow bottoms. The slimey, natural lubricant glistened in the bright glare of the overhead fluorescent lights. 

Evidently, sucking her big brother’s cock and having him cum in her mouth had turned her on a bit more than she had realized.

No. Not just a bit more – [i]a lot[/i] more.

“Heh. Well I guess we know which suit you’re going to be getting,” Kieran remarked snidely from behind Kayla’s back.

Kayla gasped and turned around, only now realizing the her brother was watching and must have realized what was going on. She looked at him in fear.

“What are we going to do!?” she asked urgently, starting to freak out about dirtying up the store’s swimsuit.

Seeing his little sister’s anxiety growing by the second, Kieran did his best to relax her. “Calm down Kayla, it’s alright. Nobody’s gonna find out – we’ll just fold them up and hide it and we’ll buy them at the self checkout or something. Okay?”

Kieran’s voice was calm and cool. His words sounded wise enough. Kayla visibly relaxed as she considered what he was saying. “Y-yeah. Okay.” The plan sounded rather foolproof in her mind. Everything was going to be okay.

The young bunny cub finished removing the swimsuit and donned her street clothes once more; there was no sense in trying the final suit since she had already “decided” which one she was getting.

After gathering up the somewhat-used yellow suit, leaving the other two suits behind, the two bunny siblings left the changing room together.

Both of their hearts skipped a beat as they realized that the clerk was standing nearby. She couldn’t have been more than 10 feet away; the gazelle had a quizzical look on her face, clearly confused about why this older male cub was exiting the changing room with this young bunny girl.

Thinking quickly, Kayla piped up. “My older brother...He was just checking on me since I was taking so long.” She gave an innocent smile and a nervous laugh, hoping that the store clerk had bought her lie.

“Ah, I see,” the clerk responded in kind with a similar, uncomfortable smile. Clearly the situation was quite awkward and all the parties involved wanted it to end as soon as possible. “Well, did you find one you liked?” The clerk quickly changed the subject to save them all from any further embarrassment.

“Y-yeah, I did.” Kayla nodded at the folded up yellow suit that was cradled in her arms.

The clerk smiled again, this time much more genuinely. “Good! Would you like me to box that up for you?” she asked politely, starting to reach for the garment.

“NO!” Kayla shouted, a little louder than was reasonable, turning her whole body to the side to keep the clerk from reaching the swimsuit. Realizing her overreaction, she hurriedly adjusted and provided a more appropriate response, “T-that is, I wanted to carry it around more, just to make sure I don’t change my mind...or something.”

Again the clerk laughed awkwardly and smiled politely, “Well...okay then!” Not wanting to draw out the situation with these strange customers any longer she quickly made up a radio call that nobody else heard and excused herself from the pair.

“Whew. That was close,” Kayla sighed to Kieran once they were alone.

“Yeah. C’mon, we still have shopping to do.”

“Yeah! Like my [i]energy drink[/i]!” she reminded him proudly.

“Yeah yeah.”

The two cubs traversed the length of the grocery section, grabbing the items that their mother had sent them to retrieve. Once they had everything in paw, they made for the front of the store and the self checkout kiosks near the exit. Kayla ran ahead, excitedly throwing open one of the little display refrigerators and pulled out a green and black energy drink. She held it up to Kieran.

“I want this one!”

Kieran rolled his eyes. “Figures. The name fits you perfectly.”

The teenage bunny scanned the various items, including the swimsuit and energy drink, while Kayla helped bag them. With a quick swipe of their mother’s credit card, they were on their way out the door. 

[i]Psssshhhh[/i]

Kayla had almost immediately cracked open the tall can as soon as they had left the store.

“You idiot. Now you’re going to have to chug that – there’s no way you’re taking that into dad’s car. Not while it’s open.” Kieran chastised his little sister’s foolishness, shaking his head as they continued to walk.

“Oh. Right.” Kayla sounded so sad and dejected. Her big prize was going to be ruined because she couldn’t properly enjoy it and would have to down it in seconds. Her shoulders slumped and she started to reluctantly drink.

Sensing her disappointment, Kieran felt a little bad for her – after all, [i]he[/i] had made out pretty damn well in this whole deal. She should at least get to fully enjoy [i]her[/i] reward. Once they had reached the car and he had finished loading up the groceries, he stopped her before she could make herself sick.

“Hey – look, you’ve probably drank enough that it won’t splash out or anything. Right? You can bring it so long as you [i]promise[/i] not to spill it.”

Kayla looked up and smiled at her big brother’s accommodation. She nodded eagerly and Kieran couldn’t help but smile back as her cute exuberance returned. They climbed into the car, energy drink in-paw, and headed for home.

On the drive, for some reason, Kieran couldn’t help but think about the energy drink mixing with his cum inside his little sister’s tummy. He glanced over at her as she took another sip from the tall can. Her throat moved as she swallowed and he recalled how it had moved in the same way when she had swallowed his load.

“Look out!” Kayla warned, suddenly removing the can from her lips.

Kieran jerked the wheel back straight; he had started to slightly veer out of the lane when he had looked over at Kayla.

“Well, no more doing that I guess,” he thought to himself.

When they finally pulled into the driveway, their dad was just finishing up the electrical connections between the camper and the minivan. The two siblings exited the sports car and Kayla dashed inside, practically sprinting. 

Kieran looked over his shoulder. “What’s her deal?” he wondered quietly to himself as he walked over towards his dad, his arms full of bags of groceries. Kieran shrugged, guessing that it was likely excess energy from the drink – that or it had made her need to pee.

“Hey dad, just got back from the store.”

“Hey son. How was it?”

What he was really asking was how was the car.

“Everything went great. No problems at all and I was super careful. I parked really far out so it wouldn’t get scratched and kept it under the speed limit.”

“Good,” his father paused for a moment, looking up to take a quick peek at the car to verify his son’s story before wiping off his paws on a dirty rag.

“Maybe sometime I can drive it again?” Kieran asked slyly, starting to walk backwards towards the front door of the house.

His dad’s response was firm but kind: “We’ll see.”

“Score!”

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

The next morning, the family of four piled into the minivan bright and early. Well, “bright” is a bit generous – it was still dark out – the sun not yet having risen from beyond the horizon. Kayla sat in the captain’s chair behind her father, who was driving, and Kieran took the other behind his mother. Both cubs fell right back asleep, practically before they had left the neighborhood. They slept past the sunrise and for a good while after.

“You kids awake back there?” their mother finally called out from the front seat, rousing them from their slumbers.

“Mhmm,” Kayla groaned, rubbing her eye with the back of her paw. She stretched and yawned, looking out the window to see where they were at. The scenery wasn’t very helpful – nothing but fields for as far as the eye could see.

Kieran was yawning too. He peered out the window at the rows and rows of corn fields flying by outside the van’s windows.

Bored. He was so bored already.

He peeked between the front seats at the dash, looking at the digital clock. 

10:06 AM.

“Wow, we slept a long time...” he remarked quietly.

“Hm?” Kayla replied, having not quiet heard him over the sound of the road noise.

“Nothing,” he replied, shaking his head. As he looked at Kayla sitting there he recalled a dream he had been having. He couldn’t remember the exact details, but he knew that they had been doing something naughty. He knew how it made him feel.

Kieran felt a slight stirring in his loins and Kayla was back to looking out the window; he took the opportunity to admire her from ear to toe.

She was wearing her usual black gym shorts that she liked to wear for lounging about, and a pastel tie-died t-shirt. Her shoes had been kicked off almost as soon as they had gotten in the van, as had Kieran’s, for the purpose of sleeping. Kayla had her head propped up on her arm, her elbow resting against the base of the window.

“Hey,” Kieran whispered, just loud enough to get her attention. Kayla turned towards him. “Wanna play a game?” he asked in the same hushed tone.

Kayla nodded excitedly. “Sure,” she whispered back, not really sure why Kieran was trying to stay quiet, but following his lead anyway.

Kieran leaned forward and pulled out an old [i]Mad Libs[/i] book from the seatback pocket in front of him. He dug around more, finding a ball point pen that had been tucked down in there with the book. The pen didn’t even have a cap, so he wasn’t sure it’d work, but figured it was worth a shot. The teenage bunny sat back in his seat and flipped to a random page. He then turned the page over, so that he could write on the blank, back side of the paper.

“I dare you to…” he wrote at the top of the page, the pen coming back to life easily.

He leaned over to Kayla, showing her what he wrote.

“Okay, so we’re gonna play the Dare Game, got it?” he informed her, still whispering.

Kayla cocked her head to the side, unsure what exactly he meant. “Like, ‘Truth or Dare’?”

“Kinda, only, there are only dares – no truths. One of us...me, starts, and I write out a dare for you. Then, you have to do the dare. If you do, you can cross it off and write a dare for me. If you don’t do the dare, you lose,” he explained. “It’s kinda like ‘HORSE’ but, you don’t have to do what the last person did.”

Kayla nodded once in understanding.

Kieran figured he’d start out easy for her and test the waters of her willingness to comply. He wrote, “kiss the window,” and handed the pad over to Kayla. She giggle as she read it and then turned and smooched the window of the van, leaving two lip prints plastered on it. She eagerly took the pen from Kieran’s paw, scratched out his dare before she scribbled something down and handed them both back.

“flip off dad”

Kieran gave her a look like “What??” but then did as the dare asked, subtly giving his own father the bird, holding his paw low so their dad could not see. Kayla’s mouth opened in protest but Kieran just smirked before she could object. “Shoulda been more specific,” he remarked in a whisper. He crossed out Kayla’s bizarre dare.

“flash ur boobs”

He handed the pad over and watched as Kayla blushed a little. However, she soon got a smirk on her face. She turned towards the window, away from Kieran, and pulled up her multi-colored shirt, baring her young, flat chest to the corn fields outside. She dropped her shirt and turned back and stuck her tongue out at her older brother, knowing she had gotten the best of him. “Shoulda been more specific,” she mocked before scratching out the dare. 

“Dammit,” Kieran thought to himself. She was smarter than he sometimes gave her credit for.

Kayla put the pen to her mouth as she tried to think of another dare. After a few moments she finally jotted one down.

“take off ur shirt”

She proudly handed the pad over to her big brother – there would be no getting out of this one. Kieran smirked when he read it. She had thought she had outsmarted him, but he was a guy after all and it was perfectly normal for him to take off his shirt if he was too hot. Still, just in case, he peeked up front and verified that their mother was still reading her e-book and their father was concentrating on the road. As stealthily as he could, he pulled his shirt off over his head and tossed it to the floor. He triumphantly picked the pen back up and crossed of Kayla’s dare before writing his own.

“show ME ur boobs” he wrote, making sure to capitalize and underline ‘ME.’

Kayla rolled her eyes when she read it; she had figured he would do something like that. She too gave a quick check up front this time before proceeding. Her body was already turned toward Kieran so she took the bottom hem of her shirt in her paws and hesitated. After taking a second to gather her courage, she lifted it straight up to her neck, this time baring her naked torso to her big brother.

Kieran admired his little sister’s toned abs, her small navel, and of course her bright pink nipples standing out against her white fur. Her chest was still rather flat and androgynous, but Kieran didn’t mind at all.

After giving her older brother a good five second look, Kayla pulled her tank top back down and crossed off his dare.

She wrote next: “boxers,” trying to save some extra writing.

She handed the pad to Kieran who just looked at her and shook his head. “That’s not a dare, dummy,” he whispered. Still, he felt bad for her and knew what she meant; he was just happy that she was starting to get the ever-escalating nature of the dare game. He pulled down the side of his shorts and pulled up on the waistband of his boxers, showing them off to Kayla. They were black with a white plaid pattern. Kayla stole her peek and blushed before smiling softly at her brother. She knew he had done her a favor by choosing to interpret her dare for her.

It turned out that her dare was very much in line with what Kieran already had in mind for his next dare.

“show me ur panties”

Kayla took the pad and read the dare before calmly setting the booklet down on the floor. Kieran wondered if he had finally come up with a dare she wasn’t willing to do. Was she quitting? However, he quickly realized that forfeit wasn’t at all what she had in mind. Instead, Kayla pulled up her rainbow-colored shirt again. She held it up with her chin against her chest, giving Kieran another look. Then, with one paw she pulled down a little on the front of her shorts while pulling up on the elastic of her underwear with the other.

Her aqua colored panties had a light pink hem around the edge and were covered in a pattern of little white stars of varying sizes. Kieran swallowed as he got a peek at what his little sister was wearing underneath those shorts of hers. He couldn’t believe just how cute, and arousing, the sight was for him. They were quite girly and he wondered if his previous comment about liking her cute underwear had influenced her choice this morning. “No, certainly not, right?” he thought to himself. Kieran could just make out the shape of her mound, hiding underneath the thin layer of cotton.

She let him look for ten seconds or so, enjoying the reaction she was causing on her big brother’s face. Finally, she let her shorts and underwear go and they both snapped back into place. She lifted her chin, letting her shirt fall back down. Kieran was blushing, as was Kayla. She gave him a smile, proud of herself for not only completing the dare but eliciting such a response from him.

Kayla took up the pen and quickly wrote down her next dare, already having one in mind.

“show me ur dick”

She eagerly handed the pad back to her older brother. Kieran read the dare and set the pad down. After a quick check up front again to verify their parents weren’t looking, he lifted his hips up off the seat and pulled down on his shorts and boxers. His large, uncut cock was freed, though it was still mostly soft. Kayla, who was turning out to be the much more daring one of the two, reached over and wrapped her paw around her brother’s organ.

“What are you doing!?” Kieran whispered angrily at her.

However, instead of replying, she simply gave him a few tugs, pulling his foreskin up and down along his soft shaft. She then released him. The effect was almost immediate: like a beast awakened, Kieran’s cock began to lift, straightening out as it became fully erect. Kayla watched with a sly smile; each time she thought it was done growing, it seemed to get a little harder, a little thicker.

Satisfied that he had more than completed the dare, Kieran quickly pulled his shorts and underwear back up. He took a second to adjust himself now that he had to accommodate the raging stiffie Kayla had given him. He snatched up the Mad Libs booklet from the floor in a huff and started to write.

“show me ur butt”

Just as he was about to hand the pad over to Kayla, he yanked it back and added a small addendum to his dare, adding “^ BARE” before the word “butt.” He didn’t want her sneaking out of this one like she had earlier.

Kieran handed the pad over to Kayla who took it and read his dare. She rolled her eyes at his obvious note, teasingly offended that he thought she’d try a dirty trick like that again. Well...maybe.

Kayla set the pad and pen on the floor and rolled onto her side so she was facing the window, her fluffy tail pointed towards Kieran. She looked over her shoulder, verifying her mother was still completely absorbed in her e-book. Content that the coast was clear, she lifted her hips off the seat slightly and pulled down the backside of her shorts, bringing her underwear along with them, until they were just past her ass.

The young bunny cub mooned her big brother, showing him her soft, round, white butt. Two faint marks, impressions left by the elastic of her panties, were visible across each supple cheek. Kieran gawked, amazed at how innocent and yet somehow erotic her bare backside was. It was absolutely perfect.

Evidently, Kayla didn’t think the dare was quite daring enough; after a few seconds, she gripped her upper cheek in her paw and lifted, spreading her ass apart. Kieran watched in awe as his little sister showed him her holes – their parents mere feet away. The bare, puckered flesh of her little tailhole stretched as her fingers gripped her backside. Her pussy lips parted slightly, forming a teardrop shape, giving Kieran a tiny glimpse of the moist, pink flesh concealed within; he could feel himself get a little harder as he peered at the entrance to her cub vagina.

He noted how her fingers seemed to sink into her butt cheeks ever so slightly, giving away just how soft it must feel. He wanted so badly to reach out and give her butt a squeeze. However, he was finding himself more and more drawn to her little asshole; he reached out, without really giving it any thought, and gently grazed the pad of his finger against her tightly-puckered tailhole. He briefly felt the soft, textured ridges of flesh brush along his fingertip before Kayla tensed up. She let go, her butt cheeks clamping down as they tightened, barring him any further access. She shot him an angry glare as he withdrew his paw. In a huff, she quickly pulled her shorts and underwear back up before sitting up straight.

“It’s only fair!” he whispered to her, “You got to touch me!”

Kayla’s mouth twisted as though she disagreed that the exchange was equivalent, but she wasn’t about to get into an argument about it. She snatched up the pen and pad, slightly annoyed at Kieran, but willing to admit to herself that he had a point. She thought long and hard about her next dare. It kind of felt like she had pushed things as far as she really could. Right? Certainly anything further would attract the attention of their parents.

“show me ur dick again and stroke it”

She handed the pad back over to Kieran who read it before dropping the pad on the floor. Begrudgingly, he pulled down his shorts and underwear again. This time, when he uncovered his cock, his erection slapped up against his shirt, leaving a tiny drop of precome staining the fabric. He very carefully and slowly wrapped his paw around his length, gradually stroking himself up and down. His steady strokes pushed another bead of precome up and out of his tip. Kayla watched intently, her eyes wide, her lips slightly parted as though she were parched, watching someone chug an ice-cold glass of water. The young bunny girl squirmed in her seat, acting as though she was simply repositioning herself for a better view; in reality, without even recognizing she was doing so, Kayla was actually rubbing her privates against the seat. She exhaled a raspy breath, a slight tingle shooting through her as she rubbed her vulva against her underwear, stimulating her clit as she discreetly grinded herself against the seat. 

Alas, it was over too quick and Kieran pulled his shorts back up, hiding his member from view. 

Kieran bent down to pick up the [i]Mad Libs[/i]. When he had dropped it, the pen had rolled underneath his chair. As he reached for it, something caught his eye: a blue Sharpie laying on the floor, tucked up against the chair rail. It was [i]the[/i] Sharpie from the other day! He stealthily picked it up in his paw as he grabbed the pen and pad. He knew exactly what he was going to do for his next dare.

“stick this in ur pussy”

He handed the pad over to Kayla; she still hadn’t noticed the marker that he was holding onto. She read the dare and looked up at him looking somewhat confused.

“Stick what?” she asked him in a whisper.

Kieran smirked as he rotated his paw and revealed the marker that he was hiding. Kayla blushed, instantly recognizing the marker from their previous escapades.

“No way! It was…” she mouthed the rest of the sentence, too ashamed or nervous to give the words sound: “in my [i]butthole[/i]!” She blushed even harder, having admitted the embarrassing truth. Memories of bending over and the funny feeling as Kieran stuck the marker inside of her butt flooded Kayla’s mind. 

“So you’re saying I win?” Kieran asked tauntingly.

Kayla frowned. 

She [i]really[/i] didn’t want to lose.

“C-could...could you at least clean it off first?” she pleaded, giving her brother big puppy dog eyes.

Kieran obliged; he took the bottom of his shirt and wiped off the marker, despite the fact it looked perfectly clean to begin with. He handed the Sharpie over to Kayla.

“And I wanna see, too!” Kieran added as she took the marker from him. He wasn’t about to let her get away with any tricks.

Kayla looked up front, nervous about how exactly she was going to do this in a manner that would be hidden enough in the event their mom decided to turn around, but still visible for Kieran. 

Finally, she turned in her seat to face Kieran, her legs hanging off the side towards the center of the van. The young rabbit cub hiked up one leg of her shorts and pulled the bottom of the leg to the side, holding it open. Kieran’s heart raced as he was able to see the outline of his little sister’s plump labia hiding underneath her light blue panties.

After yet another, quick glance up front, Kayla pulled her underwear to the side too, uncovering her immaculate slit. Kieran swallowed and could feel his pulse quicken further at the sight of her bare, naked pussy. Kayla was still laser-focused on completing the dare; with her free paw, she gripped the blue cap of the marker and guided the Sharpie up her shorts. Arriving at her lips, she slipped the round, gray end of the Sharpie into her slit, sliding it up and down, searching for her own entrance. At last, the marker seemed to catch and Kayla could feel that she had found her hole.

Gently, she pressed the marker in, inserting it into herself. Kieran watched as more and more of the marker barrel disappeared between Kayla’s lips until finally, only the cap remained visible.

“Dammit, Henry, that’s my water!” the cubs’ mother suddenly called out from the front seat.

Both cubs jumped. Kayla’s legs snapped shut, the marker still buried within her. They both tried to quickly act as casual as they could. Looking up front, they could see their dad chugging down from a disposable water bottle, their mother looking at him with stern annoyance.

“I just grabbed one! Jeez, it doesn’t matter!” he finally said, wiping his mouth on the back of his paw after finishing his drink.

“Ugh! Of all the…” their mother’s ramblings became quiet mutterings as she started digging through her purse down by her feet. “I swear I had one here somewhere…”

The cubs looked at one another, giving each other a silent nod of understanding that they should probably end their little game now.

Still, there was the matter of the marker, which was still inserted deep inside Kayla’s vagina.

Kayla gradually opened her legs back up and, keeping a vigilant watch on the front seats, reached up the leg of her shorts. She grasped the cap in her fingertips and pulled it back out of herself. The Sharpie slid out easily.

As she held it up for Kieran to take back, he noticed the barrel of the marker looked a little bit shinier than it had before – it was glistening!

Just then, the cubs’ mother turned around, spotting the marker that Kayla was still holding up in her paw.

“Ah! There we go! That’ll work – gimme that marker sweetie,” their mom demanded.

Both of the cubs froze in fear for a second, their hearts leaping up into their throats.

“T-the marker?” Kayla asked, nearly trembling but still managing to hold onto the Sharpie.

“Yes! The marker you’re holding! I want to put your dad’s name on [i]his[/i] water so he can [i]hopefully[/i] remember which one is his!”

“O-oh, okay,” Kayla replied nervously. She didn’t see that she had any other choice.

She extended her arm, passing the marker forward. Their mother snatched it up, blissfully unaware that merely seconds ago, it had been buried in her daughter’s pussy. 

Not to mention where else the marker had been.

“Ugh, it’s all slimy,” their mom remarked as she uncapped the marker and started writing on one of the water bottles. Evidently, the off-putting texture wasn’t enough to deter her from staking claim on a particular water bottle. “Where’d you find this marker?” she asked rhetorically, not even looking up.

The cubs watched in horror. They saw their mother’s pink nose wrinkle up a few times as she sniffed the Sharpie: “These markers always smell funky too.”

Kieran and Kayla looked at each other, their expressions caught somewhere between amused and terrified. Luckily, their mom seemed completely oblivious to the fact that the slick, musky fluids coating the marker, were in fact the vaginal secretions of her horny, 10-year-old cub.

After what felt like an eternity, the cubs’ mother had finally finished with the marker and replaced the cap. However, instead of handing it back to them she threw it into a grocery sack that they were using as a trash bag during the trip. “Bleh,” she remarked in disgust, wiping her paws on her jeans, glad to be rid of the sticky, smelly marker. “Must have fallen into something,” she remarked to herself. “Now keep your paws off my water!” she warned their father, evidently having moved on from the mystery of the marker.

A few minutes later, their mom and dad’s attention were back on reading and driving respectively.

Kayla turned to Kieran.

“That was close,” she whispered, even quieter than before.

Kieran nodded in agreement. “Waaaay too close.”

Kayla nodded back. “Yeah. So...who won?”

It took Kieran a second to remember what she was talking about. He grinned, amazed at the fact that she was still concerned about the outcome of their little game. 

“Let’s just call it a draw for now. Deal?” He held out his paw and Kayla smiled, taking it in hers and shaking it.

“Deal.”

She was happy that she hadn’t lost. Not to mention, Kieran’s naughty game had turned out to be rather fun and exhilarating.

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

A short while down the road, the cubs’ father spoke up, breaking the silence in the van. “Alright, we’re gonna stop for gas at the next station – the one where they have the sandwich shop.”

“’Kay!” the cubs called out in unison from the back seat.

Kieran spotted the [i]Mad Libs[/i] booklet laying on the floor and moved his foot over to it, scooting it underneath Kayla’s chair. Kayla looked over to him after realizing what he was doing and nodded in agreement. Wouldn’t want anyone finding that – they could deal with the incriminating evidence later.

The van slowed as it pulled onto the off-ramp, exiting the highway. The heavy camper strained the poor mini-van’s brakes. Again silence filled the air, with only the sound of the turn signal clicking on and off as their father waited to turn right. There was not much around in terms of services – no other restaurants or even any other gas stations. It was a fairly remote little stop, but one that they used frequently whenever they’d take the camper up to the lake.

The cubs’ father pulled into the large pump area, intended for semi-trucks and other over-sized vehicles, and parked.

“You guys want your usual orders?” their mom asked from the front seat, turning around to look over her shoulder after unbuckling her seat belt.

“Mhmm,” Kieran replied lazily.

“Yup! OH! But no onions this time!” Kayla peeped.

“Alright.”

And with that, she left the van and walked across the parking lot into the gas station and the attached sandwich shop. Their dad had already exited the van and was pressing the buttons on the pump’s keypad, answering the myriad of questions it had before he could actually fill up.

Kayla unbuckled her own seat belt.

“Hey, Kieran,” Kayla called out in a whisper.

“What?” Kieran replied back in a normal voice, not seeing a need to whisper since their parents weren’t even in the car.

“I’m…[i]wet[/i],” she responded back in an even quieter whisper, her cute little face blushing as she announced her arousal.

That got Kieran’s attention quick. His ears perked up and he even blushed a little bit. It was rather erotic hearing such a young and innocent looking cub say that – and knowing that she wasn’t talking about spilling a drink on herself or being caught in the rain; but then again, Kieran knew his little sister’s true nature – even if it wasn’t known to anyone else. Images of himself shooting his load into her open mouth flashed across his mind.

“R-really?”

Kayla nodded with a shy smile, “mhmm.” She quickly reached over, grabbed Kieran’s wrist, and pulled it over. With her free paw, she lifted her shorts and underwear away from her body before shoving Kieran’s paw down there.

“KAYLA! What are you-!”

Kieran tried to protest, but quickly fell silent as his palm came to rest on Kayla’s bare mound. His fingertips lay atop her plump outer lips, now eager to verify her claims. He slipped his middle finger between her squishy labia and against the hood protecting her clitoris. 

“Oh...wow,” he thought to himself as his fingertip was immediately greeted by warm wetness, even though he had barely dipped it between her lips. Kieran couldn’t believe just how slick she felt; if she was this wet up near her clit, how wet was she further down?

The gas pump clicked off outside, startling Kieran and causing him to jerk his paw out from inside Kayla’s shorts. As he watched their father remove the nozzle from the tank and screw the gas cap back on, Kieran absentmindedly rubbed his thumb and middle finger together, letting them glide against each other, frictionless thanks to Kayla’s juices.

“Holy fuck...so slippery…” 

A plan was quickly formulating in his mind. He just couldn’t hold back. He [i]needed[/i] to feel her more. He needed, to be [i]inside her[/i].

He watched as their father walked away from the van and attached camper, heading for the gas station entrance. Inside, the line for sandwiches was quite long, with many other travelers having the same idea about lunch. Kieran recalled how almost every time they had stopped and gotten gas and lunch here, their mom had returned before their dad, who was presumably occupied in the restroom. Kieran tried to gauge the speed of the sandwich line. Dead slow, he decided.

“C’mon, I have an idea,” he said, quickly unbelting himself and taking a hold of Kayla’s wrist, pulling her along. He unlatched the side door, throwing it open quickly.

“Wait! Kieran! My shoes!” Kayla protested, but was dragged along barefoot anyway by her big brother. 

Kieran’s footwear was also absent, a fact he had completely forgotten about until his bare feet touched the hot asphalt. “No time,” he thought to himself. He threw the van door closed and lead Kayla back to the side door of the camper. She hopped along behind him, trying to avoid touching the blacktop as much as she could.

“Kieran! What are we doing!?”

He had already turned the knob and opened up the door to the camper.

“Dad says we’re not supposed to play in there! Not while it’s connected to the van!” she reminded him as he stepped up into the camper, pulling Kayla along behind him.

“Just, c’mon!” he urged. She followed.

“Close the door,” Kieran instructed as soon as they were inside. Kayla complied, reaching out and pulling the camper door shut behind them.

“What are we doing!?” Kayla demanded, raising her voice a little. It wasn’t that she was upset, just dreadfully curious about what Kieran had up his sleeve.

“We’re gonna have a quickie. Duh,” he stated rather matter-of-factly, anxiously peeking out of the windows of the small trailer.

“What’s that?” Kayla asked innocently, tilting her head to the side, her long ears flopping over.

“Sex. We’re gonna have sex. Okay? Now go get on the bed. Hurry! We don’t have much time before mom and dad come back!”

“Oh,” Kayla replied, finally understanding, “okay!” There was a marked hint of excitement in her tone now that she knew what was going on. “OH!” she stated as if something had finally clicked in her brain. “Is that why it’s called a quickie? Because it’s fast?”

“Uh huh,” Kieran answered, only half listening. He was still looking out all of the windows to verify the coast was clear. The windows were covered up with sheer curtains that allowed him to see out, but he knew from experience made it difficult for outsiders to see in. He turned back towards Kayla just in time to see her start to climb the ladder to the top bunk. “No! The bottom bed, dork!”

“Oh.” Kayla hopped down off the ladder up to the top bunk. It was where the two of them normally slept on these family trips; the bottom bunk was typically reserved for their parents. She plopped down at the edge of the bottom bunk, her arms to the sides, gripping the edge of the bed with her paws. The young bunny cub eagerly looked up at her big brother, waiting for his next instruction.

Kieran dropped down to his knees in front of Kayla. He reached for the waistband of her shorts. Both of the cubs’ hearts were pounding; they were both at near peak arousal, both of them anxiously anticipating what was to come. Kayla lifted her hips, allowing Kieran to pull down her shorts and underwear all in one go. He quickly slipped them down her slender legs, letting them fall around her ankles. As they fell, he spied a small, dark, wet spot staining the crotch of her panties. 

“Wet. She’s [i]wet[/i]. Your little sister is wet for you and wants you [i]inside of her[/i],” Kieran thought excitedly to himself.

His gaze fell upon the perfect slit running up between her legs, ending just before her pubic bone. With her legs still somewhat closed, her vulva still concealed what lay within. It was almost as though her butt-crack continued upwards, forming one unbroken line as it extended to the front of her body.

The rock-hard, teenage rabbit hastily dropped his own shorts and boxers. His white, uncut cock stood at full attention, his foreskin already pulled back from his dark pink tip. 

Slowly, he spread apart Kayla’s knees and watched as her young flower blossomed open, revealing the delicate pink petals and folds within. Her body was completely ready for him, eagerly opening up for him as he spread her legs. He could tell her pussy lips were slightly swollen. They were also a darker shade of pink than normal; there was no doubt that she was extremely turned on.

Kieran shuffled forward on his knees, bringing his member closer to Kayla’s pussy. He took himself in his paw and lined himself up with the entrance to her vagina. Steadily, he pressed forward, watching as his head started to spread her hole open and disappear inside. However, he hadn’t even gotten his tip halfway inserted when he realized this position wasn’t going to work. 

Her legs were still too close together to make any kind of movement practical.

He withdrew himself, soliciting a confused look from Kayla. Quickly, Kieran bent down and pulled her panties and shorts completely off, freeing her ankles. He spread her legs once more, wider this time, which allowed him to scoot all the way up to the edge of the bed.

“Ready?” he asked somewhat redundantly.

Kayla nodded, biting her lower lip with anticipation.

Kieran gave once last look out the camper’s windows before finally pushing himself forward again. His dark pink tip pressed against Kayla’s small entrance, spreading it easily as he slid into her with little resistance. The young bunny cub gasped as tingles of pleasure rushed up and down her body. Meanwhile, the horny teenager was overcome by just how soft and warm it was inside of his younger sister; so much so, in fact, that he had to stop partway in, fearful that he might cum right then and there.

A more pleasurable sensation he could not imagine. 

Kayla’s insides were perfectly warm and felt softer than even the most expensive silk. She was tight enough that every single square inch of his cock came into direct contact with her wet walls as he sank into her depths. The pink, elastic flesh of her cub vagina wrapped around him, forming a perfect Kieran-shaped sheath, engulfing his member in sensational bliss as more and more disappeared inside of her. He continued to press forward slowly until finally, his hips pressed against hers.

Kayla was already panting and even Kieran let out a small, subtle moan. A car across the parking lot honked as its owner locked the doors, pulling Kieran out of his blissful hypnosis. His eyes shot up and scanned the gas station parking lot. The coast was still clear...for now.

It was then that he remembered time was of the essence. Still, he wouldn’t have done anything differently – nothing beat the feeling of that first slow, warm thrust, especially when Kayla was this wet.

Kieran grasped his little sister’s bare hips and started to fuck her properly, the shelter of the camper providing the space and privacy they needed for their incestuous coupling. Kayla’s eyes closed and she started to moan softly with each thrust, but Kieran would be afforded no such luxury. He mainly kept his eyes peeled on the front doors of the station, waiting for one of their parents to exit. Only occasionally would he allow his gaze to return to the muted-sunlit interior of the camper, to peer down at his little sister’s half-naked body as he thrust in and out of it.

Aside from the siblings’ raspy, lusftul breathing, there were only two other sounds present in the family camper: the sound of their parent’s bedding rustling as Kayla’s body shifted back and forth against it, bumping from the impact of Kieran’s thrusts; and a quiet wet squishing coming from between Kayla’s legs as Kieran’s cock plunged in and out of her now [i]extremely[/i] wet pussy. The pace of Kieran’s thrusts increased, causing the frequency of all the other sounds to increase as well. 

Even Kayla’s moans were getting louder and higher in pitch.

The glass doors at the gas station entrance pushed open and Kieran’s heart jumped; he instantly recognized the silhouette of his father leaving the building and starting over towards the van.

“FUCK!” Kieran yelled, pulling out of Kayla without hesitation. “Dad’s coming!”

He raced to pull his shorts back up. Kayla also moved quickly, sitting up on the bed and reaching down to the floor of the camper, looking for her clothes. Her shorts she found relatively quickly, but her underwear had been tossed aside.

“Hurry up and get dressed dummy!” Kieran insisted, already standing fully-clothed and straightening himself out. He tucked his erection underneath his waistband, hoping that would be enough to hide it.

“I can’t find my underwear!” Kayla cried out, still searching in a panic from atop the bed.

“Forget it! Just...put your shorts on!”

Kayla did as her older brother advised, lifting her feet straight up and throwing the shorts over them, pulling them on. Kieran was watching their father intently, his heart pounding with every step closer their dad took.

“Let’s go!” Kieran shouted quietly, ushering Kayla towards the door. She threw open the door and hopped out of the camper. At the very last second, Kieran spotted Kayla’s light blue panties underneath their parent’s bed and dove over to get them. He bunched them up and shoved them into his pocket before leaping back up and hurrying out of the camper. He threw the door closed behind him.

“HEY!” their father’s booming voice commanded as he neared the van.

“Oh shit, we’re dead,” Kieran muttered under his breath, adrenaline causing his heart to race even faster. His palms grew sweaty. His paws trembled.

“What’d I tell you kids about playing in the camper when it’s attached to the van!?” the cubs’ father yelled.

“Sorry dad!” Kieran replied, hoping to spare them both a lecture. He did his best to sound genuinely apologetic, but through the intense anxiety and excitement, it was no easy feat. The cubs dashed for the van door, Kayla pulling it open as soon as she got there. Not only was the looming presence of their angry father a powerful motivator to get back inside, but the uncomfortable feeling of the rough, hot blacktop against their bare feet hurried them along as well.

Kayla quickly climbed back inside, with Kieran right behind her, pulling the door shut. They each took a seat in their respective chairs and sat in silence, both of them trying to catch their breath. Their dad came around and got in the driver’s seat. He pulled the door closed behind himself and gave them both a stern look in the rear-view mirror.

“I told you kids not to play in there while it’s attached to the van. It’s bad for the suspension.”

Their father sounded much more calm and collected this time around, but there was still a definitely air of irritability surrounding his words. He jammed the key into the ignition and started the engine so the AC could run.

Neither cub said a word, they both just looked down at the floor. They knew they were in trouble – but oh, if their father only knew what they were [i]really[/i] doing inside the camper.

A couple minutes later their mother finally showed up with four bags of sandwiches and a cardboard drink carrier containing four sodas. She started to hand out the drinks and sandwiches before noticing the awkward silence hanging in the van.

“Uh oh, what happened?” she asked perceptively. “Were you two fighting again?” she inquired of her cubs.

Kayla and Kieran just looked up at her, knowing that their father would soon answer.

“No. They were horsing around in the camper.”

“Tsk tsk, you kids know you aren’t supposed to be doing that; it’s bad for the suspension.” 

“We know,” the cubs replied in unison, their tones ashamed and a little dull – having heard the same thing so many times now.

Their mother finally finished passing out lunch and turned her attention to her own sandwich. The cubs were just getting ready to take their first bites…

“So, what were you kids doing back there anyway?” their mom asked rather benignly, proceeding to take a bit after asking.

Kayla and Kieran both shot each other glances before both turning and answering nearly simultaneously.

“Tag,” was Kieran’s response. “Nothing,” was Kayla’s.

They then both turned to each other again, their eyes wide.

“Tag,” Kayla quickly amended her answer. Acting like she was finally admitting what they were doing.

Was it enough?

Their mother turned in her seat and looked back directly at her cubs, her eyebrow raised. But after a few seconds she decided that Kieran was most likely telling the truth and Kayla was just afraid of getting in trouble, she turned back around and took another bite of her sandwich.

Their dad had put the van in drive was pulling back onto the highway. The cubs ate their meals in silence, washing down the cheap subs with their sodas. The car was silent, except for the sound of the AC and the droning of the road noise outside. 

Kieran and Kayla kept stealing glances at each other when the other wasn’t looking. Their young libidos had been kick-started but with no resolution. Neither of them had gotten the chance to finish, yet their sexual arousal had been cranked up to 11.

The silence was broken when the cubs’ mother finally spoke: “Did you kids remember to use the bathroom at the gas station?” she asked, finishing the last bite of her sandwich.

Oops.

Kieran knew he had forgotten something. Him and Kayla both usually used the restroom at the gas station as it was one of the only nice bathrooms along the way. 

“No…” Kieran finally replied wistfully. Their mother just shook her head, failing to understand why they wouldn’t have.

She didn’t realize that her cubs’ priorities had laid elsewhere. In fact, their priorities [i]still[/i] lay elsewhere. The bunnies were as horny as they had ever been; they would have given anything to be able to hop on out of the car, scurry behind the bushes, strip naked, and fuck each other like...well, like [i]bunnies[/i]. 

Still, maybe there was another way they could slake their lust...

Kieran picked up the Mad Libs booklet and turned to a new page.

“r u still horny?”

He handed the pad over to Kayla so she could read it. She looked up at him and nodded, blushing. Kieran held out his paws, requesting the pad of paper back. Once Kayla handed it over he scribbled something else: “follow my lead”

After holding up the pad for Kayla to read, she nodded once affirmatively with a determined look in her eye. Kieran flipped the pad closed and stuffed it into the seat back pocket.

“Hey, Mom? Dad? Is it okay if I go to the backseat to nap? It’s too bright up here,” the teenage rabbit pleaded with his parents. It was true that the slightly darker tint on the rear-most windows of the van made it a bit shadier, and the cubs had requested to do the very same thing before on past trips.

Their father gave him a brief glance in the rear-view mirror, but then returned his gaze to the road, not bothering to give an answer. He didn’t care either way. True, he didn’t like it when the cubs would take naps in the back since they weren’t belted in, but on this long, straight stretch of highway he didn’t see a problem with that. Instead, it was their mother that turned around and granted Kieran permission.

“Sure, that’s fine. But haven’t you gotten enough sleep already?”

Kieran shrugged. His mom just smiled softly and turned back to her e-book. He then unbuckled his seat belt and climbed into the backseat of the van; the third row of seating in the minivan was a simple bench seat, instead of the individual captain’s chairs that made up the second row.

“Can I take a nap back there too?” Kayla asked, doing her best to figure out how to follow her brother’s lead.

Their mother turned around again. She looked at Kayla inquisitively and then at Kieran as if asking him for permission, since he had asked first. The cubs’ mother figured that Kayla had simply wanted to do the same thing that her big brother was doing, just because he was her big brother. After all, it wouldn’t be the first time.

“Yeah, that’s fine,” Kieran answered. “She can lay in my lap or whatever.” He did as best to sound nonplussed about the whole situation.

Their mother gave Kayla a single nod of approval and then turned back to her e-book again, hoping that was the final distraction. She was about to find out who the killer was!

Kieran sat in the seat directly behind his own chair, now two rows behind their mother. Kayla stopped between the chairs, looking to Kieran for guidance.

“Lay on your tummy, across the seat, and put your head in my lap,” he instructed in a hushed voice.

“’Kay,” she whispered back.

The young bunny girl laid down across the bench seat just as her big brother had instructed, laying her head down in his lap.

“Hold on, lift your head up for a sec.”

Kayla did as asked; Kieran pulled down his shorts and boxers, uncovering his bare cock. He was only semi-hard now, but Kayla knew what to do. She wrapped her small paw around his member; instantly he started to get hard at her gentle touch.

As soon as her big brother was hard, Kayla jerked him a couple times, sliding his foreskin up and down his length. She pulled it back and a drop of clear precome emerged from his tip. The young bunny cub moved her head in closer and licked it off of him. The contact of her warm, wet tongue against his sensitive tip made Kieran grow even thicker. His balls ached, eager to achieve the sweet release that they were denied earlier.

Meanwhile, Kieran reached down over Kayla’s fluffy, white tail and slipped his paw underneath the waistband of her shorts. He ran his paw over her bare butt, giving each cheek a gentle squeeze. He couldn’t believe just how incredibly soft her young backside was; the pliable flesh molded to the shape of his paw as he kneaded it gently. His fingers meandered over to the top of her crack and he started to slide them down the length of it. Kayla tensed slightly as Kieran’s fingertip brushed against her asshole for the second time today as he continued on down. Kieran pressed his middle finger against the warm folds of Kayla’s inner lips, feeling the wetness coating them. After a quick glance up front, verifying their parents were still occupied, he curled his finger inward, slipping it into her vagina.

Kayla, who was by now giving Kieran a full-on blowjob, let out a very soft, muffled moan as her brother’s finger penetrated her. Her lips were wrapped tightly around her big brother’s cock as she moved her head slowly up and down, licking him all over. She didn’t want to move too quickly as she didn’t want to attract any attention, giving away what they were really up to in the backseat. She sucked on him, her eyes closed, focusing on the pleasurable feeling coming from between her legs. Kieran wiggled his finger around inside of her, causing Kayla to squirm and moan again. Each time she moaned, her mouth vibrated around his cock, enhancing the stimulation he was receiving.

Kieran started to move his finger faster, thrusting it in and out of Kayla’s tight fuckhole, his knuckles rubbing against her g-spot. Kayla moaned again, losing some of the focus on her task of pleasuring Kieran. She was getting close and he could tell. He increased his speed, finger-fucking Kayla as quickly as he could given the awkward angle and trying to remain discreet; he was determined to push her over the edge. The teenage rabbit pushed his finger in as far as he could, moving his whole hand around, his middle finger moving wildly every which way inside of her.

At last, Kayla moaned around Kieran’s cock again, this time a bit more loudly and drawn out. Loud enough that Kieran was a little worried about their parents hearing her. Her legs tensed up and her butt clenched. Kieran’s paw was trapped, his finger locked inside as all of her muscles tightened. The powerful walls of her vagina pulsed around his finger. The young bunny cub’s fluffy tail twitched in time with her orgasmic contractions, tickling the bottom of Kieran’s wrist.

Kieran waited patiently as his little sister rode out her climax, her breathing and heart rate peaking, making each labored breath she took audible as it traveled through her pink nose. Throughout her entire climax, Kayla somehow managed to keep her mouth wrapped securely around Kieran’s length; granted, her concentration had long since vanished as she focused solely on her own pleasure.

Gradually, Kayla seemed to be coming back down, her body relaxing, her breathing returning to normal. Kieran started to pull his paw out from inside her shorts, but stopped and decided against it. Instead, he took a nice squeeze of her ass before finally reinserting his finger into her pussy. He figured if his dick couldn’t be inside of her, then at least some part of him could be. As Kayla resumed giving him head, it was like his finger provided a kind of mental connection, helping him imagine that he was fucking her – just like they had been back in the camper.

“Wait a sec…” Kieran thought to himself, coming up with yet another way to get more of his senses involved. After a quick peek to make sure that Kayla’s eyes were closed, he reached into his short’s pocket with his free paw and felt Kayla’s underwear. There were still balled up from when he had hastily stuffed them in there earlier. He very carefully pulled them out, making sure to keep them concealed inside his paw, just in case she were to open her eyes. 

She didn’t. Instead Kayla was still sucking away, her tongue sliding up and down Kieran’s length.

The teenage rabbit opened his paw once it was above his sister’s head, out of her line of sight. The light blue cotton panties unfurled open. Kieran shifted the underwear, finding the inside of them – the part that only a bit ago would have been pressed directly up against Kayla’s labia. He lifted her panties to his face and pressed his nose against them. They were still a bit damp and he felt a touch of wetness on the tip of his nose. He drew in a deep breath, inhaling her scent. 

His little sister’s sweet feminine-musk filled his nose, causing his heart to race. The aroma was distinctly girly, unique to Kayla; at least, Kieran had never smelled anything quite like it before. It aroused him in ways he couldn’t comprehend, speaking to some primal part of his male biology.

He now had a trifecta of sensations: his finger buried inside Kayla’s warm vagina, her mouth wrapped tightly around his cock, and her scent filling his nostrils. The combination almost seemed to give him a slight euphoria. 

Meanwhile, Kayla focused her attention on her brother’s tip, repeatedly sucking it, her tongue pressing against his glans. Kieran could feel himself moving closer and closer to his own climax – but, something was missing. 

He wanted more. 

He wanted the real thing. 

It was like his body had tasted the ultimate pleasure and now it would settle for nothing less. Kayla sucked and licked, but still Kieran couldn’t seem to achieve that release he so desperately needed.

“Do you kids need the bathroom?” their mom asked from up front, starting both cubs. 

Luckily, their mother was still looking down at her e-book, not even bothering to look up to ask the question.

Kieran quickly shoved his paw containing Kayla’s underwear back into his pocket and withdrew his other paw from her shorts. Kayla removed Kieran from her mouth and responded back.

“Yeah, I do.”

Kieran shifted, shimmying his shorts up and over his erection, readjusting himself in the process. 

Kayla turned her head up towards him and frowned. “But...you didn’t get to…” she whispered, trailing off at the end. 

Kieran gave a sad smile and shrugged his shoulders.

The van slowed as it pulled off of the highway towards a rather remote and desolate rest stop. The parking lot was completely empty, devoid of any people or other vehicles. Large, shady trees covered the ground around the lone, brown brick building. Two small ventilation chimneys extended from the roof, but otherwise the rest stop bathroom was rather unremarkable.

As soon as the van had come to a stop, the cubs hopped up and climbed out of the sliding door. They both stretched, their backs arching and their arms reaching high above their heads. Kieran groaned, partly from the stretch but also from all the unreleased sexual tension that had built up in his loins. 

He had been brought towards the edge twice, only to have circumstances steal his chance at relief away from him. Kayla’s head was tilted back as she continued to stretch, basking in the warm sunlight. Kieran studied the lines of her slender neck, the way her colorful shirt pulled up from her waist as she stretched, revealing her midriff.

The two cubs started off towards the building. The bathroom on the front was labeled as the men’s, but there was a heavy padlock and an “Out of Order” sign hanging on the front of the door.

“Guess you’ll have to use the girls!” Kayla teased before giggling and running off towards the back of the building, determined to be first.

“Yeah, or I could just go in the woods,” Kieran remarked back, reminding her that he did have the same requirements she did when it came to using the restroom. Kayla turned back towards him and stuck out her tongue before disappearing into the women’s bathroom. Kieran heard the heavy lock latch shut and the indicator above the handle turn red to “Occupied.”

“Myeh myeh myeh myeh myeh myeh myeh~” Kieran mocked his little sister’s taunt as he wandered back towards the tree line. He stood at the edge of the thick, bushy forest and pulled down the front of his shorts and fished out his cock. He looked back over his shoulder, verifying his privacy; the building obscured the van from view and Kayla was still in the bathroom. Kieran was still semi-hard and he gave himself a couple half-hearted tugs; he had to pee, but what he really [i]needed[/i] was to cum. The stimulation brought him back to full hardness, his body excited that maybe now it would get the satisfaction it so greatly desired. The teenage bunny boy gave himself a few more tugs, pulling his foreskin up and down his length. A large drop of clear precome formed at his tip before slowly dripping towards the ground, dangling as a long string before finally dropping onto a leaf below.

Kieran sighed and concentrated on urinating; after all, he [i]did[/i] have to pee and didn’t want to miss the opportunity. He relaxed and started to go. He was amused at the great distance he was achieving, his pee arching through the air several feet into the forest as it left his still-erect penis. He let go with his paw and let his raging hard-on hold him in place as he continued to pee.

“Wow…” a small, soft voice said from behind Kieran’s back. It was Kayla’s voice. She must have finished and managed to sneak up on him.

Kieran looked over his shoulder. “Kayla!” he stammered. He was embarrassed, but unable to stop the flow. He did his best to keep his back turned to her, but the young bunny cub just moved around him, curiously watching as her big brother continued to urinate, a steady stream expelling from his hard cock.

“So that’s how boys go…” Kayla remarked again, slightly in awe.

“I’m gonna kill you...” Kieran threatened, finally finishing up. He shook off the last few drops and pulled up his shorts and turned to chase down Kayla. His little sister let out a playful scream as she took off back towards the building.

“Wait! Wait! Kieran! Wait!” she pleaded, coming up against the building and shielding herself with her arms.

“What?” Kieran demanded, holding his fist back as if he was just waiting to strike her arm.

“I...I had an idea when I was going to the bathroom,” she remarked, her voice going a little quiet. 

She blushed. Kieran waited for her to explain.

“What if...we had another quickie? You know...like before?” she suggested, blushing a bit more.

“[i]Here[/i]?”

“In there,” Kayla replied, pointing towards the door to the women’s restroom. “That way, you could maybe...you know?” She was suddenly too shy to express what she meant.

“Hmm…” Kieran lowered his fist, instead stroking his chin thoughtfully. He peeked around the corner of the building; their parents were still waiting patiently in the van, not paying any attention. “Alright, if we hurry…”

Without another word Kayla took a quick step towards the door, she opened it and her and Kieran entered the rest stop bathroom. It was hardly the most romantic setting, in fact it was even a little repulsive, but Kieran was willing to take what he could at this point. The pangs of discomfort from blue balls were starting to set in. This was no longer about simple teenage lust and hormones. 

He [i]needed[/i] this.

“There, by the sink,” Kieran instructed.

Kayla marched over to the sink and dropped her shorts, letting them fall around her ankles. She reached back with her paws and spread herself open. Kieran gawked as his little sister spread her privates for him, offering up her holes for his use.

“Hurry up!” Kayla commanded, reminding him they didn’t have much time before their parents would start getting suspicious.

Kieran nodded and came over behind her, dropping his own shorts and underwear. He took his stiff cock in his paw and squatted down behind her, lowering his hips enough so they could get underneath hers. He guided himself towards her entrance and felt the warmth radiating off of her as he neared it. The teenage rabbit pressed his tip against her soft, fleshy hole and pushed up into her.

Kayla was obviously still aroused herself, as Kieran was able to slide in rather easily. Once he was inside, Kayla let go of her cheeks and gripped the edge of the sink. Kieran tilted his head back, letting out a pleasured sigh as he was once again engulfed by Kayla’s tender, young flesh. He gripped her naked hips and started to thrust in and out of her. He very quickly picked up the pace, the fire within him demanding more and more and more. His hips slapped against her butt, echoing in the small concrete bathroom.

Kieran looked down and into the mirror. He could see Kayla’s face, her eyes closed, her expression locked in a grimace of pleasure, her mouth open slightly as she breathed heavily. Her floppy ears bounced each time Kieran’s hips would impact her. It all looked so immodest, so out of place on an otherwise innocent looking cub. Yet here she was, looking just as pleasured as the girls Kieran would look at online – only this time Kieran knew for sure that it was genuine. 

[i]He[/i] was the one making his little sister feel that good and there was no denying just how much she was enjoying it.

Kayla started to moan as her big brother’s cock pounded in and out of her. It was all getting to be too much for Kieran: the sweet sound of his little sister’s sweet moans and their bodies slapping together filling the small rest stop bathroom; the feeling of her warm, eager pussy doing everything it could to help him achieve release; and her blissful expression, twisted into a grimace of perverted pleasure. He could feel himself quickly approaching the point of no return and he slammed into Kayla harder. Her sneakers struggled to maintain contact with the floor as he pushed deep up into her, lifting her onto her toes.

Kieran’s seed erupted violently inside of Kayla. He moaned loudly as his balls contracted, almost painfully, finally getting to release their pent up contents. His cock pulsed powerfully each time it injected more and more of its virile payload deep inside his little sister. Kayla could feel the sudden burst of warmth inside of her and knew that Kieran was finally there. Kieran’s head was spinning and he felt a little dizzy; he steadied himself on Kayla’s hips as he finished cumming.

The two cubs peered into the mirror, looking into each others eyes. Both of them were panting, basking in the afterglow of their bathroom quickie, out of sight and achieving a totally different kind of relief than what their parents had had in mind. Kieran finally pulled out and took a step back. Immediately, several large globs of his thick, white cum leaked from between Kayla’s legs, splattering loudly on the gray concrete floor. A few cloudy drops clung to her pussy lips, and a few more had dripped onto her shorts.

“Oops,” Kayla remarked quietly, noting the mess they had made.

“Don’t worry about it,” Kieran assured her, “the bathroom is dirty anyway. It’s not like anybody is going to know that it was us, or even what [i]it[/i] is.”

Kayla shrugged and started to dispense some paper towels from the holder to wipe herself and her shorts clean with.

“Oh yeah, here,” Kieran pulled up his shorts and boxers and reached into his pocket, fishing out Kayla’s panties. He held out his paw, offering them to her.

“[i]You had them the whole time[/i]!?” Kayla asked in disbelief, snatching her underwear out of Kieran’s paw. She kicked off her shorts and shoes, standing barefoot on the bathroom floor.

“Gross,” Kieran commented at his little sister’s apparent lack of concern.

Kayla just glared at him and stepped into her panties, pulling them up snug around her waist. She pulled her shorts on again and shoved her feet back into her shoes.

“C’mon, let’s go,” Kieran urged, unlocking the bathroom door and opening it to the bright sunshine outside. It took a second for his eyes to finally adjust.

“Wait for me!” Kayla called out after him, running out just behind him. The door slammed loudly closed behind them.

They strolled back towards the van as casually as they could.

From behind, Kieran heard Kayla pout.

“Aw man!”

He turned around, continuing towards the car, walking backwards. “What?”

“Some more of your white [i]goop[/i] just leaked out into my underwear!” Kayla quietly announced.

Kieran swallowed and pulled at his shirt collar. Guess they’d be getting back into the family minivan with Kayla’s panties full of his cum. “Sorry,” he muttered as they neared the van. Kayla just glared at him and scrunched up her face.

They got back in their seats and Kieran pulled the shut door behind them.

“Where were you guys? Another few minutes and we were going to go get you,” their mother warned.

“Well, [i]Kayla[/i] took forever and the other bathroom was locked so I had to wait around for her…” Kieran started.

“NUH UH!” Kayla loudly protested, cutting off her brother.

Their mother just looked back at them and rolled her eyes. Looked like her cubs were back to their usual bickering and the peace they had shared all morning had all but run out. The family pulled out of the rest stop and got back on the highway, headed for the lake.
