Kissing Cousins

Snapping awake with a gasp, Sarah quickly sat up in her bed, the 12 year old mare tossing aside her blanket as she quickly turned to her phone, grabbing it up to check what time it was, only for her to discover she still had an hour to go before her alarm was set to go off. Sighing, the girl laid her head back down on her pillow, her hands resting on her belly, idly stroking at her chestnut brown fur as she stared up into the ceiling, knowing she wouldn't be able to get a wink of sleep even if she tried. With a groan and a shake of her head, Sarah finally just hopped out of bed, dressed in just her panties as she grabbed her towel and walked out of her room, heading straight for the shower. Passing by her parents' room on the way there, the equine perked her ears up to hear his dad still snoring away, sighing with worry as she stormed into the bathroom, worried that they'd somehow be late even though the sun wasn't even up yet. For over a month, the little filly had been waiting for this day, as his cousin was flying down to stay with them for a few weeks, and she didn't want a single second of their time together to be wasted on him having to wait around at the airport to be picked up. Though the boy was almost six years older than Sarah, having turned 18 at the beginning of the summer, Henry and her were very close friends, at least so it seemed from an outside perspective. In reality, the colt and her were much more than friends, with the pair always sneaking away from the crowd whenever they saw one another at some family reunion, finding a quiet cubby to hole up in and explore one another's bodies. Stripping off her panties, noticing the wet spot on the front of them from the very fun dreams she'd had during the night, Sarah stepped into the shower, unable to resist giving the winking equine slit between her legs some particular attention while slathering up her coat, having to hold a hand in front of her muzzle to keep quiet as she leaned against the wall, rubbing at her clit and shivering at the thought of finally getting to see the young stallion again, managing to shake off her lust for just long enough to finish up with her shower. 

While the girl quickly dried off and found some clothes that she knew her cousin would love, slipping on a top that left her belly partially exposed and a pair of tight jean shorts, her parents finally woke up as well, thankfully oblivious to the true nature of why their daughter was so excited to head out and pick up their nephew, constantly checking the status of his flight on her phone while they sipped their morning coffee. After waiting around for a few more agonising moments that just seemed to drag on forever, pacing around the house and trying to think of any way to get her mom and dad to hurry up, Sarah's parents were finally prepping to leave, the young mare already hurrying to get her shoes on and stand at the door as her dad was still searching for the car keys. Stepping out, the equine family headed for their car, a big van with three rows of seats, coming in particularly handy when bussing the neighbourhood kids to and from sports practice and such. Sarah jumped into the back as her parents took the front seats, her mom chuckling at her fiddling with her mane as the woman clicked her seat belt on, glancing over her shoulder at the cub, 
"Antsy to see your cousin again?" 
Blushing lightly as she quickly looked away from her mom and out the window, Sarah nodded, 
"Uhh… yeah, I guess…" 
"Aww, that's so sweet!"
Smirking to herself at her mother's cluelessness about just how eager she was to see the colt again, Sarah settled in for the ride as they pulled out of the driveway, leaning against the door and staring out the window as the rosy blush on her cheeks only grew more intense, fantasising about what all her and the boy would get up to during his visit. 

With half an hour of driving under their belt, the trio of horses finally spotted the pickup terminal, Sarah's eyes scanning the crowd of people until she spotted a tall colt with mottled grey and white fur, and a blond mane tied into a tail, her eyes lighting up as she pointed at the young man,
"That's him, he's right there!" 
Jumping out of the van the moment it came to a stop, Sarah sprinted towards Henry, giggling and laughing as she lept on him, wrapping her arms around the chuckling boy as he returned the hug, 
"Henry!"
"Nice to see you too~" 
With her parents a few steps behind her, the filly clung to his cousin for a little while longer before hearing her dad snickering at her excitement, quickly letting go of the boy and clearing her throat as she grabbed one of the bags he had with him, unable to wipe the smile from her face as the two young equines constantly peeked at one another, her parents seemingly not noticing the tension between the pair as the mother gave Henry a hug as well, if a considerably shorter one, 
"So nice to see you again! Let's get you settled in, the van's just over here."
Walking side by side behind her parents, Sarah subtly reached out to hold her cousin's hand as the two eyed one another up, smirking at his eyes lingering on her thighs, her choice of outfit seemingly working wonders on the pent up stallion. 

Letting Henry clamber into the van before her, watching as he slipped into the last row of seats, Sarah sat down in the middle row, wanting a little room between her and the colt out of fear that she might not be able to control herself if sitting side by side with him, afraid that her parents might've already been getting slightly suspicious because of her excitement about him visiting. Pulling the door closed with a sigh, leaning back and peeking over at the sly smile that Henry had on his muzzle, returning it before turning back to her parents. Leaving the airport behind them, the filly's dad let out a little happy sigh, keeping his eyes on the road as he glanced at his nephew through the rear view mirror, 
"So, did ya have a good flight, everything go okay?" 
The boy nodded while yawning, stretching his arms, 
"Yeah, it was pretty decent. Cramped like heck though, they don't design those airplanes for taller folk like me."
The mother shook her head, 
"Sorry to make you sit in the car for another half an hour."
"Oh, it's okay, gonna feel like nothing after the few hours on that flight." 
Feeling her heart fluttering slightly, getting more and more impatient by the second, Sarah winked at her cousin, 
"Maybe you need a massage, just a deep rub after sitting still for so long~" 
Missing the two foals quietly snickering with one another in the back, the dad spotted a long line of cars snaking off into the horizon ahead of him, the flashing lights of a few emergency vehicles blinking in the distance, giving a groan as he pressed on the brake, almost coming to a complete standstill as Sarah looked over at the traffic jam in horror, 
"Wait, what's happening?" 
"Dunno, looks like maybe some sort of an accident up ahead or something, all the lanes are completely clogged up. Guess we're stuck here until it clears up."
With her giddy mood instantly turning into storm clouds, the filly's smile disappeared as she watched the traffic jam moving at barely walking pace, slumping back with an annoyed huff. 

As one minute turned to five, and then ten, soon nearing half an hour, Sarah flopped onto her back with a groan, lying across the seats with nervous frustration bubbling up in her chest, feeling the time dragging on with the car barely even having moved at all. The girl felt like every single second that they spent in traffic meant one precious and intimate moment less that her and Henry could spend enjoying one another's company, grumbling to herself as she stared out the window at the lines of cars seemingly stretching out to infinity ahead of the van. Her cousin lived far enough away that every time the pair got to hook up was a special treat, and here they were with their entire first day together seemingly a complete wash, wasted on sitting in traffic without the chance to as much as fondle one another with her parents sitting within an arm's reach of them. Sarah had hoped, and planned that by this time the entire family would already be back at their place, and that she and Henry would already be sneaking to their usual hideout nook in the basement laundry room, with the boy's hand stuck down the front of her shorts and her fingers wrapped around his thick shaft. The filly's fantasising only made the slow crawl towards the city that much more torturous, making her horribly horny in addition to the anxiousness, leaving her pouting on the second row of seats with her arms crossed and her knees squeezed together, feeling her panties sticking to her pussy lips as she tried desperately to hold out for long enough for the van to make it home. 

The little mare wasn't the only needy equine in the car however, with Henry sporting a big bulge in his pants, leaning down over the backrest of the second row of seats, staring down at the younger cousin's tantalising body, his eyes flitting between her and the traffic jam as he huffed, gently rubbing at the lump in his pants before finally deciding to go for the plan he'd been hatching in his head, tapping Sarah on the shoulder and whispering to her, 
"Hey, I think we could… you know, have a little fun back here~" 
Sarah glanced at his parents, noticing that the line of cars was moving just enough to force the pair to keep their eyes on the road rather than paying any attention to what was going on in the back, getting the cub hopeful about Henry's plan. Sitting up and leaning over her dad's shoulder, the girl did her best to hide her smirk as she put on her innocent voice, 
"Hey, since we're gonna be stuck here for a while, you don't mind if me and Henry watch a movie or something on the screen in the back, right?" 
The man nodded, longing while tapping the steering wheel idly,
"Sure, go ahead."
With a mischievous grin, Sarah immediately turned around and crawled over a folded down seat to the back row with the older foal, quickly folding the seat back up as Henry fiddled with the screen built into the back of the row ahead, putting on some random movie for some noise to hide their true intentions, the filly's heart skipping a beat as she looked down at the hefty bulge in his pants.

Within ten seconds of the filly's change of seats, her hands were already rubbing on her cousin's tented pants and her lips were locked together with the colt, the pair ducked down just enough to hide their perverted embrace as Sarah felt her heart beating a mile a minute. Not content on letting his hands stay idle either, Henry returned the favour with some groping of his own, taking the girl and lifting her onto his lap, their crotches pressed together as he cupped a handful of her lovely rump, giving her ass a squeeze as they made out. Huffing and panting as their tongues wrestled in one another's maws, the two equines put all of their pent up lust and desires into the sloppy and frantic kiss, pressing their bodies together, the sounds of their sweaty smooching just barely hidden underneath the sounds of the movie and the noise of the traffic around them, though that didn't exactly do much to ease the cub's nerves. Sarah's chest heaved up and down as she let out a tiny moan into the older boy's muzzle, shivering as her tail whacked the back of the seat behind her, trembling both out of excitement at finally getting a taste of the colt once more as well as due to her anxiousness at getting so adventurous pretty much right in front of her parents. Pushing the filly's crotch against him even harder as he began to gently rock back and forth in his seat, keeping one eye open to watch for any signs of his uncle or aunt catching onto what was happening in the back of the van, his cock giving a throb and spewing out strands of sticky precum into his boxers as he humped the younger cousin sitting on his lap, swirling his tongue in her throat. With every movement of the adults in the front making his heart leap, too worked up to even think of stopping even in such a risky spot, Henry broke off the kiss between him and Sarah for just long enough to nudge the girl onto her back on the row of seats, leaping on top of her and pressing their lips back together as their panting filled the van, the cub squirming around and clawing at his back as he grinded his erection against her tight shorts, nearly bringing them both to climax just from the dry humping alone. 

Pinned under the bigger horse, clinging onto him tight as she bucked her hips up against the bulge poking at her shorts, shaking and blushing heavily as she grew desperate for her cousin to just take her right then and there, Sarah had almost forgotten about her parents sitting just a step or two away from her, snapping to reality at the sound of her mother turning to her father, 
"Well, we're gonna be stuck here for quite a while I guess. Think we ought to save as much gas as we can, since you didn't fill it up yesterday, right?" 
The man gave a sigh and a nod, 
"You're right, only thing worse than this is if we ran out of juice midway through and had to wait for someone to haul a can of gas to us."
The dad clicked off the air conditioning before rolling down the windows, almost instantly turning the inside of the van sweltering hot from the summer sun, helped only slightly by the occasional gust of air blowing through the windows. Of course, the cousins in the back of the van were already sweaty and hot under the collar, so neither cared much about the heat being cranked up a few notches. In fact, the added noise of the other cars helped to further cover up the wet smacking sounds of their makeout session, giving the boy the confidence to take it one step further still. Sarah panted as the colt broke off their kiss, her mane spread out on the seat under her as he reached his shaky hands down to the buckle of his belt, cringing as it made a metallic clink in the process of him undoing it, his eyes anxiously darting around between his extended family and the passengers of the other cars all around him as he zipped his jeans down, lifting his shirt slightly as he looked down at the girl underneath him. With an equally nervous smile, Sarah grabbed the colt's boxers and slowly pulled them down to his thighs, having to bite her lower lip to keep from moaning out loud at the sight of his cock bouncing up, standing stiff and pointed right at her face as she grabbed the underside of it with one hand, slowly stroking it while reaching down into her shorts with the other hand, her fingertips dancing across her soaked pussy lips as she whispered, 
"I need you~!" 

Though dreading the mess that both him and his taboo sweetheart would land in if either the girl's parents or the people in the cars surrounding them spotted him and Sarah, Henry knew just as well as the cub that he couldn't say no to her pleading, not after the hot and heavy foreplay that had left him huffing and puffing, shivering as he stared down at the little mare jerking him off as she panted, his shaft twitching and spraying ropes of precum onto her belly. Holding his breath, trying to duck his head down as much as he could, nuzzling his cheek against Sarah's as she quietly whimpered into his ear, the young stallion opened his cousin's shorts and tugged them down, pushing her drenched panties off to the side as the girl planted his leaking tip right against her entrance, rubbing it up and down on her lips as the pair both shivered, clinging to one another and staring into each other's eyes. With a pleasured grimace, Henry slowly pushed into the cub, momentarily freezing in place at the sound of a strained whine coming from her, glancing at the adults in the front to make sure they hadn't noticed it before pushing deeper still. With their chests pressed together, the colt could feel Sarah's heart thumping just as rapidly as his, both foals terrified of being caught but desperate for one another at the same time, too far gone to even think of stopping now. Seeing her dad in the corner of her eye through a gap between the seats, unable to focus solely on the feel of her cousin's girth throbbing in her pussy no matter how hard she tried, Sarah tried her best to keep from moaning, her back arching and rising off of the seats with every inch that the colt stuffed into her mound, her wet lips winking around the boy's cock as he let out a barely audible gasp against her fur, kissing and licking at her next to try to keep himself from making any further sounds. Thinking he might've heard some heavy panting coming from the back of the van, the dad turned his head slightly as he shouted out, not enough to catch more than a glimpse of the back,
"You two aren't getting too hot back there, right?" 
With a look like he'd been caught in the middle of a murder, his eyes wide and sweat pouring down his face, Henry quickly raised his head just above the seats, trying to force a nonchalant smile on his muzzle while nearly balls deep in the man's daughter, praying the dad hadn't seen her underneath him, 
"N… no, w… we're fine!" 
Squirming and kicking as both the pleasure of getting bred and the thrill of her parents being right there overwhelmed her, Sarah clamped a hand around her muzzle to stay perfectly silent until her dad turned back to the road, feeling like she was about to explode when Henry quickly leaned back over her, nudging her hand out of the way and taking her in another passionate kiss just so the pair could both stifle their moans more easily, planting the last few inches of his cock into the mare while she moaned into his maw. 

Hilted inside of his cousin down to the very last inch, his tip half flared deep inside of her as his sack rested on her thighs, the colt began to thrust in and out of the girl while their tongues were still intertwined, trying to go slowly so as not to make too much sound, a shiver running up his spine at the thought that her parents could spot them at any second as her walls gripped his thick shaft. Sarah's eyes rolled back in bliss as she took the stallion's cock, gasping and whimpering as she humped her hips up against the boy's girth, forcing him to go faster and faster as their bodies rubbed together, drool and sweat running down her muzzle as she toed the line between rutting the stallion as hard as she would've liked and trying to stay hidden from her parents. Usually, the taboo couple would've either pinched a condom from the filly's dad or just pulled out when nearing climax, the cub having become somewhat of an expert at swallowing down Henry's big loads after letting him finish in her maw so many times, but they didn't have the luxury of either in the back of the van, with the older equine going in bare and not wanting to risk making a huge mess all over the seats if he were to pull out. Of course, the fear of ruining the seats was mostly just an excuse Henry told himself, an even bigger obstacle to shooting his load somewhere other than his cousin's cunt being his own lust, desperate to fill up the little mare with his seed, all thought of pulling out disappearing as her tunnel squeezed his flaring tip. Sarah certainly didn't want the boy to deposit his load anywhere but deep inside of her womb either, still locked in a kiss with him as she moaned softly, her entire body quivering before she suddenly saw stars, cumming harder than the colt had ever managed to get her to. In a chain reaction, Henry was forced into a climax of his own just seconds after the filly, embracing her as he gave a short grunt, his entire length pulsing hard in her slit as his flare grew to full size, locking the pair together as he began to pump his seed inside of her. Shaking while clinging to one another, the horse stared into each other's eyes while riding out their orgasms, trembling while desperately trying to stay silent. 

Slowly calming down, the cousins finally broke off their kiss while Henry was still hilted in the girl's equine mound, panting and gasping quietly as he pushed himself up to his knees, barely able to stay up as his shaft pulled out of Sarah's pussy an inch at a time, popping free as a big glob of cum rolled out of the winking slit, smearing into her brown fur as she quickly pulled her panties back over her cunt. In a hurry to hide their perversions, the foals both sat up and scurried to zip their pants back on, still out of breath as they collapsed into their seats with a huff, their manes and their clothes dishevelled, a healthy blush on both of their faces as they glanced at one another with smirks. Cuddling with one another, the cousins were glad to see that their parents didn't seem to have noticed anything, both still just staring ahead, trying to keep track of the traffic jam. The mother spotted a sign for a diner, pointing at it as she turned to peek over her shoulder, 
"How's this, we pull in and have a nice breakfast while we wait for this darn traffic jam to break up?" 
Grinning, Henry looked down at the filly leaning against his shoulder, secretly stroking her thigh, 
"What d'ya think?" 
Hiding her smirk as she felt the boy's cum drooling from her pussy, soaked up by her fur and panties, Sarah nodded,
"Yeah, I think I've worked up enough of an appetite that a few pancakes would be nice~"
