While digging through caves to find priceless treasures, Flitter and Cloudchaser soon learn that the underground tunnels won’t be the only ones being explored.

Flitter and Cloudchaser have long since breached the taboo of inappropriate sibling relations. As the two sisters explore ancient ruins and temples with their team, confusing feelings and heartfelt moments lead to more intimate situations than most teammates usually have.

Hey, there’s nothing wrong with building a little physical camaraderie, right?

These clop chapters are part of my larger story, A Different Kind Of Treasure. You don’t need to read it, but if you want the context of the clop, I’d recommend reading that first.

I hope you all like the new cover-art. The amazing artist NixWorld drew it, and I am blown away by its quality. Check him out if you want high quality art!

Sibling Bonds

Cloudchaser closed the bedroom door with a snap. Chuckling to herself, she turned to look at her similarly giggling sister, Flitter.

As they laughed, Cloud snickered, “I never expected you to be so good at seduction, sis. You’re usually so shy when guys ask you out.”

Flitter gave another laugh as she replied, "It’s a lot easier when I actually like the stallion I’m flirting with. It was surprisingly simple to convince Sky to let us sleep in his apartment for tonight. If I tried my hardest, I could probably have him make us dinner too~”

They both snorted as Cloud sat on the bed next to her. Wrapping a wing around Flitter’s barrel, she hugged her sister and whispered, “Thanks for forgiving me. I swear, I never tried to steal him away from you. Those little moments we had together were just spontaneous impulses. They didn’t mean anything serious.”

Flitter returned the embrace and cuddled their torsos together until it was hard to tell whose hooves were whose. “It’s okay. I’m sorry for lashing out at you. I can understand why you wanted to do those things with him. He’s a really great guy.”

“Yeah, he really is,” Cloud sighed before shaking her head. “Uh, I mean, he’s going to be a really good catch once you manage to lure him in with your charm. After all, until you officially ask him out, he’s still on the market. If you don’t act soon, another mare might make her move and snatch him up.”

Flashing back to the way Nurse Redheart had unashamedly groped Skyfall’s flank, Flitter nodded before asking the question that had been bugging her all day.

“How do I ask him out? I mean, I know how to say the words, but what if he gets weirded out by my awkwardness?" She turned to look at her sister with a pleading gaze. "I know you’ve had a few partners before, so I was wondering if you had any… you know… advice.”

Cloudchaser rubbed her wings in a comforting manner. “Just relax, sis. Don’t stress the small stuff like how or when you’re going to ask him out. After all, I’m pretty sure he already likes you if his confession in the dungeons was anything to go off of.”

Flitter looked up in surprise. “Wait, was that confession meant for me? With the way the light was shining, I couldn’t tell which of us he was talking to.”

A glimmer of hope flashed in Cloud’s eyes before she quashed it down. Forcing herself not to think about their intimate moments, she gave a half-grin, half-grimace and stammered, “Y-Yeah, that confession was definitely meant for you. Considering the way he was gawking at you during your date, I’d say he definitely likes what he sees.”

“Wait, you saw us?” Flitter asked, not remembering her sister’s presence during her and Sky’s romantic trist.

“Of course I did. After all, with how many guys that were eyeing you up, it was kind of hard not to notice your uninspired clothes,” Cloud muttered, a hint of jealousy peeking through her low tone.

The two sisters sat in silence before Flitter stood up and started towards the bathroom. “Okay, I’m going to get ready for bed. Let me know if you think of anything else I can use to ask him out.”

Cloud nodded and started changing into her nightshirt. As she removed the fabric from her bag, a pair of deep purple panties caught her eye. Raising them up, her muzzle split into a mischievous smirk as she glanced at the door Flitter was showering behind.

“Don’t worry, sis. I’ll show you everything you need to know about stallions~”

Flitter felt like a new mare. As she shook her mane, the cleansing water flicked onto the shower walls and floor. Reaching for the nearby towel, she gazed appreciatively at her pristine reflection in the mirror.

Her wet, seafoam-green mane plastered itself to her neck as she dried herself off. Grinning, she admired her own beautiful, feminine features as she gave the second Flitter a sultry, half-lidded gaze. Turning around, she twerked her soft, perky barrel and flank, giggling as she imagined the type of reaction Sky would have to her seductive advances.

Having raised her self esteem a few notches, she exited the bathroom and got into bed. Cloudchaser was already lying there, apparently sleeping if her low snores were anything to go off of. Smiling softly at her exhausted sister, Flitter climbed under the warm covers and flicked out the lights, plunging the room into total darkness.

As the surrounding night began to take it’s hold on her, Flitter’s eyelids began to feel heavy. With one last contented sigh, she rolled onto her side and closed her eyes, ready to welcome sleep with open hooves.

Suddenly, Flitter felt a warm foreleg wrap itself around her torso. Waking up again, she turned around to find a pair of lidded purple eyes gazing at her with a sultry look she wasn’t sure she liked.

“Cloud? What are you doing?”

Cloudchaser smirked as she brought their barrels closer together. With her extended hoof, she pulled Flitter even closer until the two sisters could feel each other’s body heat through the covers. With her signature cocky grin, she smirked, “You did ask me for advice on how to ask him out, didn’t you?”

Flitter’s face scrunched in confusion. “Yeah, I did, but how is cuddling like this going to help me with that?” Her cheeks started to grow warm at the close, intimate contact with the dominant pegasus. Even though it was just her sister, it still made her heart rate kick up a few beats.

Cloud’s other hoof reached under Flitter’s barrel as her wings unfurled to add another layer of contact to the already intimate hug. “Well, if you ever want to be able to ask a guy out, you’ll need to know a few things about yourself first~”

“W-What are you doING!?” Flitter squeaked as Cloud’s back hoof reached under her tail. After feeling the unexpected grope, she tried to wiggle out of Cloud’s embrace, but the more muscular pegasus held tight to her prey.

“Cloud, what are you doing!? Have you forgotten that we’re not in our house? It’d be gross doing it in somepony else’s bed!”

Cloud’s smirk grew as she whispered, “Do you really feel that way? After all…” she picked up one of the pillows and pressed it against Flitter’s muzzle, “this is Sky’s bed, which means his smell is all over it.”

Flitter tried to resist her sister’s advances, but the intoxicating masculine scent of Sky’s pillow was drowning out her higher thinking brain and replacing it with a much more instinctual thought process.

With one last rush of defiance, she pushed the enticing pillow away and stuttered, “N-No, Cloud… we… we can’t do it here. If Sky walked in, he’d see us doi~Ahh!”

Anticipating her sister’s resistance, Cloud glided her back hoof against Flitter’s inner thigh, just outside of her damp labia. The spark of arousal caused a shiver to shoot up the quivering mare's spine along with a twitch of her furled wings.

Chuckling at the reaction, Cloud started massaging her sister’s crotch area, never straying too close to keep her in a frustrated state. “So, what do you think about it now?”

“C-Cloud, seriously~Mmh! We… we shouldn’t be doing this! Sky is right outside that door.”

As her struggling became less and less resistant, Cloud laughed at the unsurprisingly quick turnaround. Both sisters had been intimate with each other before, so Cloud had Flitter’s sexual weaknesses nailed down and knew exactly how to exploit them.

Bringing her muzzle close to Flitter’s ear, she whispered, “Oh yeah, I think you’re getting into it now. Are you sure you don’t want to do it? Because I can stop if you don’t need this…”

Flitter’s panting muzzle opened, but the only sounds that came out were more muffled whimpers of confused pleasure as her sister continued her teasing strokes. As the incredible torture continued, Cloud reached down to her own marehood and began touching her outer lips, adding her own voice to the chorus of moans.

Before long, Flitter started bucking against Cloud’s probing hoof as it danced around the place she so desperately needed filling. Cloud chuckled at her impatience and decided to humor Flitter’s unspoken plea.

Repositioning herself to gain better access to her sister's dripping folds, she slowly pressed her hoof on the tiny nub that winked desperately for attention.

“AHHHmmmff!” Flitter cried out in ecstasy as a stronger lighting strike of pleasure surged through her body. Her wings poofed out as the muscles in her back started to contract and relax without conscious thought.

Feeling left out, Cloud started to pick up the pace on her own lower lips, gasping as the intense feelings increased with each delicate rub.

After several minutes of soft gasps and quiet moans, Flitter turned to glare at her. “C-Come on, sis! Stop teasing me like this! You know it’s h-heat season right now, so just hurry up and d-do it already!”

Cloud adopted another flank-eating grin and quipped, “Oh? I thought shy Flitter didn’t want to do it on Sky’s bed. Are you going to be a naughty little filly~?”

“You~Mmmhha! You started this… so you’re going to finish it. I’m sick of hoofing myself all the time, so you’re going to finish me off, or so help me Celestia I will fill you with so many holes you could satisfy fifty stallions at once!”

Cloud’s eyebrows raised at her sister's assertive tone. Normally, Flitter was always the demure, submissive one during intercourse while she took the lead with her more brazen personality.

Narrowing her eyes, Cloud decided to teach her a lesson about who was really the dominant sister. As Flitter’s moaning whimpers raised to a near scream, she pulled her hoof away from the aching, needy folds that still required a hair more stimulation to give Flitter her desired climax.

“Nngh… Cloud… why’d you stop?” Flitter fixed her sister with a disapproving grimace. “I swear, if you plan on leaving me like this, I’m going to~ A-Ahnngg!

Her voice hitched as she squeaked in surprise when Cloud’s soaked foreleg pressed against her backdoor. As the well-lubed hoof wormed its way into her cheeks, the muscles in her flank contracted in fright, effectively sealing the tighter, lesser-used entrance to her body.

Flitter panted into Sky’s pillow, absorbing the musky scent of a virile male, which only served to increase her arousal. Too overwhelmed to speak properly, she stammered, “C-Cloud! What the hay are you d-doing to me!? I never agreed to do stuff b-back there!”

The domineering mare maneuvered her hoof in Flitter’s flank, causing her to moan at the unfamiliar pleasure. “I think you need to be reminded who the lead mare is in this relationship,” she taunted, drawing out a gasp from the shy pegasus with a quick love bite. “After all, only big mares get to order other ponies around. The smaller ones…” she shoved her hoof into her sister's newly loosened tunnel, “have to take what they’re given and be happy with it. Understood?”

Flitter was too preoccupied with the hoof currently up her backdoor to reply. As her sister pressed against her most private region, a new wave of sinful pleasure wracked through her quivering body. “Ooooohhhhh, C-Cloud, you’re in my… Aaaaahhhhh…”

Cloud’s cocky grin widened at her sweet moans of pleasure. With her sister’s tunnel sufficiently lubed up, she began pistoning her hoof inside Flitter’s secondary intake, causing more high-pitched gasps to chorus through the musky room.

As Flitter reveled in ecstasy, Cloud whispered, “You like that, don’t you, sis? You like having my hoof up your flank while I play with myself. You like sniffing Sky’s pillow and imagining it was him doing this to you, right?”

“Ye~Mmmpphhh! Yes… I love it… it feels soooo good,” Flitter panted, a small trickle of drool making its way out of her mouth and onto Sky’s scented pillow. As she started adjusting to the feeling of Cloud's hoof in her rear, something else snaked its way around her barrel and started playing with her soaking pussy.

“AHHhhmmp! MMhhhh, HHhaaaaa!~”

The double stimulation was becoming too much for the shy pegasus. As she thrashed around trying to furthur stimulate herself, Cloud slowed down her minstrations to keep the desperate mare just barely off the cliff of sweet release.

Flitter let out another groan of frustration at the second cruel denial. “Clouuuuuud… stop pulling away! I’m so close…”

Cloud knew exactly what she was doing. With a massive smirk, she pulled her soaked hoof out of her own sopping pussy and placed it right next to Flitter’s muzzle while positioning her remaining hoof on the sensitive wing muscles in her back.

“Do you want this, Flitter?” she giggled, pressing her fluid-stained hoof directly onto her sister’s panting muzzle. “Do you want me to make you cum?”

Flitter didn’t reply with words, instead opening her mouth and sucking the juices off her sister’s hoof as an answer. The closet dominatrix chuckled and forced the soaked hoof further into her sister's wanting maw. “Well then, I hope you’re ready for this!”

Cloud shoved three of her hooves deep into every crevice of Flitter’s body. The poor mare's eyes widened with shock as she let out a muffled scream from the feeling of every sensitive nerve firing at the same time.

“AHHHHH!~ Ahhmmphh, hmmmn! Mmaahmnnn…~”

Flitter’s mind exploded as the floodgates opened. Her inner walls frantically squeezed down on Cloud’s hooves, trying to milk them for something they couldn’t provide. Electric shocks of pleasure coursed through her body, causing several more resounding moans and gasps to echo throughout the apaetment. Her hips rocked back and forth, desperately trying to prolong the incredible sensations for as long as possible.

Flitter’s convulsions of pleasure lasted a while longer before she collapsed in a sweaty, musky, fluid-stained heap. The sheer strength of the orgasm had completely drained her of energy, causing her used passageways to loosen up enough for Cloud to remove her hooves from their sticky confines.

Cloud stared open-mouthed at the mess on Sky’s bed. Grinning, she licked the hoof that had been in her sister’s pussy and smirked, “Damn, you really need to jerk off more often. If I had to guess, I’d say you haven’t hoofed yourself in over a week!”

Turning her attention to her own aching folds, she flirted, “Now that I took care of you, how about returning the favor?”

Flitter couldn't respond as the incredible orgasm knocked her out cold. Seeing her starry-eyed sister collapse in pure orgasmic pleasure, Cloud rolled her eyes with an annoyed huff. “Oh, great. Now what am I supposed to do?”

Reaching down, she started rubbing her own folds until the familiar tingling pleasure caused her to squirt out a fair amount of her own fluids onto Sky’s disheveled bedsheets. It wasn’t the best orgasm she’d had, but it would do for now.

Turning to gaze at Flitter’s unconscious form, Cloud smiled and wrapped a lavender hoof around her sister’s barrel. Leaning in, she cuddled the exhausted mare's adorably fuzzy coat and whispered, “Good night, sis. Have fun explaining this to Sky in the morning~”

Putting On A Show

Sky stared blankly at the unyielding door to his bedroom. After blinking several times to make sure this wasn’t one of Luna’s cruel pranks, he flattened his ears and groaned, “I can’t believe I actually fell for that.”

Thinking back, he decided that it wasn’t entirely his fault. True, he had let his smaller head do the thinking for him instead of the main one on his shoulders, but Flitter’s exceptionally cute pout and entrancing gaze had captivated him before he had a chance to resist her alluring advances.

Sighing, he stared longingly at the wood panels that prevented him from collapsing onto his blissfully soft mattress. “Well, looks like I’m taking the couch tonight.”

Sky had fallen asleep on his couch before, but being cajoled into giving up his bed was definitely a first. With another grunt of annoyance, he plopped onto the sofa and made himself as comfortable as he could be in the slightly lumpy cushions.

When his head hit the armrest, a sudden wave of fatigue crashed over the overworked muscles in his body, causing him to let out a massive yawn. Taking one last glance at his bedroom door, he closed his heavy eyelids and drifted off into the warm embrace of oblivion.

“~Ahh!”

Sky’s eyes flew open as a shout reached his ears. Perking up, he glanced around the shadowy apartment, wary of anything that might suggest an imminent attack.

Seeing nothing of interest, he glanced towards his bedroom where the noise had originated, but several seconds passed before his drowsy mind finally came to its senses.

“Oh my Celestia! They’re being attacked!”

Jumping off the couch, Sky crouched down and crept his way over to the door. Making as little noise as possible, he reached out and grabbed the closest thing he could find: A scented candle. With his makeshift weapon in hoof, he slowly edged around the doorframe and planted an ear to the wood, desperate to hear that the two sisters were safe.

What he heard next simultaneously relieved and confused him.

As he pressed his ear to the door, his senses were greeted by the sounds of heavy breathing and panting. Furrowing his eyebrows, he leaned closer and tried to pick up any signs of a struggle, but neither sister had shouted or uttered a cry for help. Just as he was about to force open the door, Flitter’s voice gave another cry that stopped him dead in his tracks.

“C-Come on, sis! Stop teasing me like this! You know it’s h-heat season right now, so just hurry up and d-do it already!”

Sky’s brain froze as his jaw dropped to the floor. Punching himself in the barrel to make sure this wasn’t a dream, he pulled away from the door and stared in disbelief at the opaque surface blocking him from witnessing the spectacle on the other side. “N-No way… There’s no way those two are actually…”

As if answering his question, Cloudchaser’s sultry tone floated through the closed door. “Oh? I thought shy Flitter didn’t want to do it on Sky’s bed. Are you going to be a naughty little filly~?”

If Sky had been shocked before, it was nothing to how he felt now. After hearing Cloud’s domineering taunt, he staggered back, tripping over his own hooves. Making his way over to the couch, he shook his head and forced his rapidly beating heart to calm back down by taking deep breaths. “Come on, don’t be so surprised. They did mention that they’ve done it together before...”

Settling back into the sofa, he wrapped himself in the camping blanket Cloud had lent him, but falling back asleep proved to be near impossible. The moment he heard Cloud’s confirmation, the familiar tingling sensation in his crotch started calling the shots. Despite his efforts, the poor stallion didn’t stand a chance against the girls’ tantalizing voices as his sheath peeled back to reveal his pride and shame.

Sky gave a grunt of annoyance at the package that was now pressed against his barrel. Shifting around to get into a more comfortable position, he winced when the soft fabric of the cover brushed against his sensitive fleshy pole. “Damn it, Cloud, now what am I supposed to do?”

Cursing the closet dominatrix for her arousing voice, he suddenly realized that she had sabotaged his male libido in more ways than one. As he fidgeted in his cocoon of warmth, a powerful scent hit his nostrils with the force of a royal carriage.

Pulling the camping blanket away, Sky sniffed around to find the source of the strange, yet alluring smell. After several seconds of tasting the air, he narrowed down the best word for the mysterious scent: overpowering.

With each intake of breath, his senses seemed to dull as the heady fragrance surrounded him and blocked out any external thoughts. Instead of trying to eliminate the source, he found himself focusing on breathing in as much of the entrancing musk as his lungs could hold. With one final rush of adrenaline, he took in another breath of the delectable scent before zeroing in on his target.

When Cloud had lent him her camping blanket, she had apparently forgotten to mention that the cover hadn’t been washed. As the buildup of weeks worth of mare-musk flooded his senses, Sky had one more epiphany that broke down any semblance of self-control he had left.

This time of year was heat season, and mares tended to give off certain pheromones when trying to attract a mate.

At this revelation, his member stiffened to the point that just existing was creating a strain in the covers. Giving up any hope of calming down naturally, he frantically whipped aside the enticing blanket and pressed his muzzle deep into its fuzzy confines.

Instantly, Sky’s senses were overtaken by the smell of a mare in heat. The breeding sections of his mind kicked into overdrive as his hips started to buck back and forth, desperate to find the fertile mare giving off the incredible scent.

As his motions became more frantic, he popped out from the delicious fabric and turned to stare at the bedroom doorway where not one, but two undeniably sexy mares were currently going at each other on his bed.

Making up his mind on the spot, he leapt off the couch again and stalked towards the only thing barring him from The Garden of Eden. With trembling hooves, he contemplated barging into the room, but managed to hold himself back after considering the sisters’ most probable reaction.

Contenting himself to just the audio portion, he leaned against the wooden frame and closed his eyes, desperate to hear anything happening inside the sacred chamber.

“AHHhhmmp! MMhhhh, HHhaaaaa!~”

The sound of Flitter’s pleasured groans caused Sky’s phallus to twitch with excitement as his hooves began to stroke the sensitive flesh. Before long, the sisters’ moans and gasps had reduced his mind to a steamy puddle, incapable of thinking about anything except breeding and sex.

A shiver passed through his spine when a particularly strong jolt of pleasure brought him even closer to his peak. Gripping his member, Sky desperately tried to hold back the imminent flood of seed, not wanting the once-in-a-lifetime opportunity to end too soon.

As his angry loins slowly retreated from the height of pleasure, Cloud’s taunting sneer floated through the closed door, causing his semi-erect rod to instantly harden into diamonds.

“Do you want this, Flitter?”

“Do you want me to make you cum?”

Sky’s eyes flew open as he stared slack-jawed at the place where the two sisters were undoubtedly pleasuring each other with wild abandon. Frantically, the horny stallion grabbed Cloud’s musk-filled blanket and pressed it against his drooling muzzle. The distinctly savory smell of her heat made his dick throb with anticipation, begging to find a nice, warm tunnel to explore.

After filling his lungs with the powerful aphrodisiac, he shifted his hooves and placed the soft fabric onto his aching penis, thrusting into the heavenly sheet. Even with the added feeling of Cloud’s heat, he still needed a tiny bit more stimulation to reach his desired peak.

That final push would come in the form of Flitter’s ecstatic cry as her sister’s sensual assault finally paid off.

“AHHHHH!~ Ahhmmphh, hmmmn! Mmaahmnnn…~”

The erotic sound of Flitter’s pleasured screams was just enough to tip him over the edge. Sky clenched his eyes shut as his intense, almost painful release jettisoned several days worth of cum all over Cloud’s blanket. As his throbbing member continued to ejaculate more of his seed, his hooves clenched down hard, desperately trying to prolong the incredible sensation.

Load after load of hot, sticky goo splattered all over the incriminating bedsheet as he raised a hoof to his muzzle to stop himself from moaning out loud. Panting with exhaustion, his shaking back legs rubbed against the cover’s fuzzy material, causing the warm sludge to drag across his hypersensitive glands.

“Oh, f-fuckkk…”

When the last few drops of semen dribbled down his twitching shaft, Sky pulled the cum-soaked rag off his dick, wincing as the sticky substance stuck to his sensitive head. Leaning against the bedroom door, he heard one last pleasured groan from Cloud before the two sisters went silent, evidently finished with their impromptu performance.

Sighing, he glanced down at Cloud’s white-stained sheets with a mix of satisfaction and disappointment. As a particularly large glob slid down the furry fabric, his receding hormones cemented the growing feelings of shame brewing in his guilty conscience.

“Damn it…”

Reaching towards the ruined blanket, he folded the corners together and lifted it up until all the evidence pooled together into one large puddle. Basking in the afterglow of his orgasm, he was struck by the sudden urge to lick up the sexual fluids until the cover was wiped clean of his shameful release.

Breathing in the heady mixture of his own seed and Cloud’s powerful musk, he felt his neck start to lean in towards a splotch of cum, tongue extended to taste the irresistible concoction of mare and stallion.

Before he could give in to his instinctual desire, a sudden rush of cold air snapped him out of his entranced stupor. Widening his eyes at the warm goo less than an inch away from his muzzle, Sky whipped his head back and pushed the drenched cover away in disgust.

“Nuh uh… No way I’m doing that!”

Still reeling from his draining release, he stood up on shaky legs and stumbled towards the washing machine. Not wanting to awaken the sleeping sisters in the next room, he buried the blanket under a pile of dirty clothes and reminded himself to start another cycle.

With the warm, sticky evidence taken care of, Sky fluttered his wings and drearily plopped down onto the couch, reveling in the cushions’ newfound comfort. Rolling to his side, he scrunched his muzzle and groaned as a faint whiff of Cloud’s heat scent wafted off his coat.

“Celestia damn it, Cloud."
