Girls' Night Out

- Horndog D -

It was a dark and stormy night.

That's an awful cliché, I know, but I wouldn't say it if it wasn't true. And just to get all our clichés out of the way right up front, the storm was a real humdinger. I nearly jumped out of my fur when the window above the kitchen sink lit up with a burst of light and a stack of dishes rattled under a massive rumble of thunder. The surprise of it startled me more than anything.

Not that I had time to pay much attention to anything happening outside. I had a dinner to fix, and the process was chaotic enough without a pot boiling over or something burning because I got distracted. A call to the fire department was the last thing I needed on my very first night in charge of the house.

Mom and Dad had gone off to celebrate their anniversary, booked into the same hotel where they spent their honeymoon up in some little town three hours north of the city. Sort of an annual tradition of theirs. The year before that, my sister and I spent the weekend with a babysitter; a year later, I was seventeen and deemed old enough to take care of things while our folks were away. Because the prospect of running the house filled me with a kind of excited glee that no self-respecting teenager would ever admit to feeling, I had to play it cool. It was tough to hide how thrilled I felt, though, even after the parents handed me a list of prohibited activities that vetoed just about everything you'd think to call fun. No alcohol, no parties, no boys, no friends over past ten... No matter. I was too high on the strange and wonderful sense of power to let anything get me down. Plus I've always been lucky in that my sister and I get along well enough to have fun with just each other.

"Something smells good!"

I looked up from the stove to see Lacey standing in the doorway, her feline tail swishing behind her as she stared at me expectantly. I knew immediately what she wanted. "I could use some help, Lacey. Would you mind setting out the silverware?"

My little sister saluted affirmatively and set to her chore while I tried not to laugh. Even at ten years old, she was obviously hungry for a taste of the responsibility she saw me enjoying. It was us girls against the world that weekend, and Lacey eagerly helped with anything I asked in order to feel like we were a team.

Another bolt of lightning ripped through the sky outside the window, a roar of thunder following moments later. When drops of rain began splatting against the glass, all thoughts of leaving the house lost their appeal. Suddenly, the ban on using the car after dark bothered me a lot less than when I'd begrudgingly agreed to it.

I finished preparing dinner and brought two steaming hot plates of tuna tetrazzini into the living room where Lacey and I ate in front of the TV. We came into the middle of a cheesy 80s action flick on one of the uncensored movie channels. In a weirdly ritualistic sort of way, exposing ourselves to cartoonish levels of violence and repeated F-bombs solidified our newfound sense of independence.

As we watched the movie, light periodically flashed through slits in the curtains while clashes of thunder momentarily drowned out the audio. After a particularly loud boom vibrated through the walls, the screen in front of us went black. "Oh, hell," I said, already aware of what would happen next. Before the "hell" even made it past my lips, every light in the house died at once, plunging us into darkness.

Lacey screamed, sounding more excited than afraid. "It's the end of the world, Clara!" she squealed, almost laughing.

"We probably just blew a fuse." I felt my way through the dark, thankful for feline vision that allowed me to see in the almost pitch black, even if only well enough to make out basic shapes. I peered out the window to find the street lights all out and the neighbors' houses as dark as ours. "Damn. Lightning must've knocked out the whole power grid. It'll probably be a couple hours before it comes back on." I didn't have the faintest clue how long it would actually take whatever company to restore our power, but the situation seemed to demand I say something informed and authoritative.

Somewhere behind me, Lacey said, "I wanted to see how the movie ended."

"It probably—" The storm interrupted me with another explosion of thunder. "...We'll look it up online when the power comes back on."

With the ambient drone of the furnace and the hum of the refrigerator silenced, the rain pounding against the roof seemed surreally loud. Focusing my senses harder, I could hear the soft patter of footpaws on carpet diminishing into the distance. I followed them to the sound of a closet door opening, then a blinding whiteness overtaking my vision. "Lacey! Not in my eyes!"

"Sorry." She moved the flashlight's beam away from my face and began pointing it at everything else, inspecting our surroundings as if seeing them for the first time.

"C'mon, let's get the other light from the garage." I let Lacey lead the way, watching as the light bounced along in front of us. I felt proud of my little sister. A lot of cubs her age would be scared out of their minds to be trapped in a thunderstorm with no electricity, and here she was treating the whole ordeal like a fun adventure. I did my best not to let on that I was starting to have fun, too.

Her enthusiasm waned only briefly while we were in the garage, which even I had to admit seemed eerily cave-like in the dark. We found the camping lantern hanging beside Dad's workbench and sprinted back to the living room as if being chased by something, both of us giggling. The lantern's LEDs illuminated the room well enough that we barely missed the lack of any other light source.

After finishing dinner, we sat back on the couch and listened to the rain with the threat of boredom looming over us. I gave Lacey a teasing smirk. "So you're not scared at all, huh?"

She shook her head, blond pigtails whipping against the sides of her face. "Nope! The dark's kinda cozy."

"Yeah. It sort of is..." My vision strayed to the transom window above the front door. I watched a small patch of sky for awhile, hoping to catch the sight of a lightning bolt streaking across the clouds—no such luck. My attention turned back to Lacey when I heard the rustle of fabric. I looked over just as she pulled her t-shirt off over her head. "What are you doing?"

"Gettin' naked," she answered with an impish grin.

Her actions came as a surprise, but not a complete shock. Lacey and I have always been very open with each other, even for sisters. We emphasized the casual in casual nudity enough that getting changed in each other's presence was never a big deal, and even took showers together during a two-week stretch when a broken water heater left hot water in short supply. Perhaps most telling of all, it had been only a few weeks since I accidentally walked in on Lacey masturbating in her room. Because I knew an apology would only make things feel awkward, I instead opted to congratulate her on taking a brand new step toward adulthood and told her she was free to ask me any questions she might have. The cheeky little bitch had only one question for me: "Does this mean I get to watch you do it now?"

I tried to think of a reason I could give Lacey to keep her clothes on, but nothing came to mind. As temporary ruler of the household, I gave my silent blessing as she hopped off the couch and proceeded to strip off her pants and underwear. She stood beaming proudly in her birthday suit, her hands clasping behind her back. The swirling tabby pattern across her belly looked like the spiral of a galaxy in the cool light of the lantern.

Still smiling, Lacey grabbed my arm and pulled me to my feet. "Okay, now you get naked, too."

My heart rate picked up and I felt warmth bloom across my cheeks. The thought excited me, but it seemed irresponsible—exactly why, I couldn't pin down. Stripping was one of the few things not included on the list of forbidden activities Mom and Dad had compiled.

"Alright, alright," I groaned. "But I'm just going down to my underwear in case somebody comes to the door or something."

Lacey looked disappointed that I wasn't going bare fur, but seemingly bought the bullshit excuse I fed her. I don't think she blinked once the entire time I spent removing my shirt and bottoms, folding each as I went. Finally I was down to my bra and panties, able to revel in the experience of being almost nude in an unfamiliar part of the house. The sensation was more exhilarating than I'd expected.

"I'm totally jealous of your boobs," Lacey said. Before I could react, her hand grabbed my left breast, squeezing it roughly through my bra. "They're all nice and squishy."

I half-yelled-half-laughed at the surprise groping and instinctively recoiled with my hands raising to cover my chest. "Lacey! Haha, you little pervert!"

"Mine are soooo small. It sucks." She gave the barely-there mounds of her own breasts a vigorous rub, then lightly pinched each nipple. "Think yours'll get as big as Mom's?"

"I dunno. Maybe." I glanced down at my cleavage and wondered. Our mother has a stunning figure with curves in all the right places, long legs under a thin waist, and a pair of tits I'd even caught a couple of my girlfriends staring at. Mine were well enough on their way that I could already fill out a C cup, but I had my doubts I'd ever sport a rack as impressive as Mom's.

"Think mine will?" Lacey asked, still toying with her hard little nipples.

"Doesn't really matter, Lace. You're perfect just the way you are right now." I snatched her up under her arms and pulled her chest against my face, nuzzling my nose into her fur and shooting a lungful of breath against her skin.

Lacey howled laughter and struggled against my grip until I set her back down on her feet. She jumped back, then spun around and wiggled her ass in my direction with her tail twitching in the air. "Catch me!" she shouted a second before she took off running.

I gave chase, following half a dozen steps behind her as she raced around the lower floor. I thought I was letting her win our game of tag until she slipped under the table in the dining room and faked me out, doubling back while I ran in a different direction. I cut through the kitchen and dashed into the living room to see her bounding up the stairs. Vaulting over the couch to reach the staircase, I jumped two steps at a time to catch up to Lacey just as she reached the second floor. Something primal stirred inside me, prompting me to lunge at my sister in a flying leap off the top step. I tackled her to the floor and rolled her onto her back, blowing more air against her stomach as she shrieked laughter and writhed fruitlessly against my grip.

Before long, my lungs had depleted. I flopped flat on my back beside Lacey, panting hard. She stared at my heaving chest a moment, then casually reached over and squeezed one of my breasts. "You don't give up, do you?" I said between gasps.

Lacey grinned. "They just feel so nice."

I pulled myself into a sitting position, still trying to catch my breath. The heat in my body and the dim light shining up from the lantern in the room below us made me feel safe and relaxed. "Alright, fine. Here..." I reached back to unhook my bra, then let it fall off my chest. Breathing instantly became easier.

Lacey practically crawled into my lap as she stared wide-eyed at my exposed tits. She pawed at them with a look of fascination, bouncing each jiggling orb in her palms and rolling my nipples between her fingers. I told her to cut it out, but my quiet moans of protest didn't even elicit a response.

My breath caught in my throat when Lacey gingerly ran her tongue over my right nipple. She watched my face for a sign of disapproval; when none came, she latched her lips onto the sensitive bud and began to suckle as if expecting a drink of milk. I shuddered at the sensation. "Your tongue tickles..." I mumbled. Without thinking, I began to stroke the back of her head, lightly running my fingers through her silky soft hair. After a few minutes, she switched to my other breast, her eyes meeting mine as her little pink tongue drew circles around the areola. I closed my eyes and moaned softly—and just like that, the feeling vanished.

I blinked my eyes open to the sight of Lacey standing at the top of the stairs wearing that impish grin of hers. "Did that feel good?" she cooed.

"I... Yeah, it did."

"You want me to do it some more?"

My hand rose to touch the stiff nub of my nipple still wet with Lacey's saliva. "Yeah."

"Then catch me!" The bratty kitten stuck out her tongue before mounting the banister and sliding down to the first floor, giggling as she ran out of sight.

Again I chased after her, mildly annoyed on the surface but inwardly glad to release some of the energy making my muscles itch. Halfway down the staircase, I realized my panties were wet in the crotch. Nothing more than an involuntary reaction to having my tits sucked, of course. If Lacey asked, I could simply tell her it was sweat.

I ran around the entirety of the lower floor without spotting my sister. Figuring she'd changed the game to hide-and-seek, I headed for the living room to grab the flashlight when my ears picked up the whine of a door hinge. Only one door in our house squeaked that loudly. I headed to the laundry room and confirmed my suspicion, finding the door to the back patio wide open.

As is typical with summer storms, the downpour had ended as abruptly as it began. The sky hung tranquil and quiet except for a faint whistle of wind pushing a mass of gray clouds. Under those clouds, the backyard sat bathed in darkness. I took a few tentative steps onto the patio, calling for Lacey in whispers. Once my eyes readjusted to the low light, I spotted the outline a figure between the plum trees near the back fence.

I jogged across the lawn to find Lacey standing in the middle of the yard, still naked as a jaybird with a pair of fingers hooked in her pussy. "What are you doing out here?" I asked.

"I've never been naked outside before. It feels really good!"

I glanced at the neighbors' houses on either side of our yard. Their black windows reminded me of camera lenses, and I couldn't be sure how much of us anyone peeking out might be able to see through the thick gloom of night. The thought that someone could maybe glance out and get an eyeful of our naked bodies sent a shiver charging down my back all the way to the tip of my tail. Lacey wasn't wrong; being naked outside did feel pretty damn good.

Stepping carefully across the slippery wet grass, I walked to the waist-high chain link fence marking the edge of our property and looked at the line of trees growing in the green space between our yard and the neighborhood park. Lacey came up behind me and said, "Everything looks kinda different in the dark, huh?"

I nodded. "Yeah."

A wicked thought crept into my mind—the kind of thought a responsible young lady placed in charge of her home definitely should not be having. I spent a few seconds deliberating with myself before making my decision: Fuck it.

I climbed over the fence, then helped Lacey do the same. "Come on!" was all I said, and all I needed to say. We ran together into the dark strip of forest, wet leaves sticking to us as we traipsed blindly through the foliage, then burst into the park at a full sprint. We made it halfway across the clearing before I had to stop and catch my breath; Lacey ran ahead, laughing as she held her arms out like she was flying. She darted to the top of a small hill and stopped short, her head tilted back. I couldn't see her face, but I expect her jaw dropped the same as mine when I looked up.

The clouds overhead tore apart like clumps of cotton, revealing a long strip of the night sky. With no light pollution around us for miles, the stars burned so bright and so clear they looked like they could be plucked out of the air. I lifted my arms above my head and could've sworn the Big Dipper was twinkling an inch beyond the reach of my fingertips.

As the breeze swept away the clouds and more of the sky opened up, Lacey and I danced together in the starlight. Never before had I felt so utterly free. Feeling courageous, I pulled off my panties and twirled them around my finger like a party spinner. Lacey applauded, delighted that I'd finally joined her in going au naturel. I thought about tossing my last piece of clothing on the ground, but then realized the potential danger of leaving my underwear in the middle of the park. Cue another wicked idea.

"Hey, Lacey! Watch this...!" I squatted down and wadded my panties into a ball, then shoved the ball into my pussy. I continued to poke it deeper and deeper, feeling a sensual thrill when the sight of the fabric vanished between my lips. I pushed knuckle-deep up into my twat, then stood bow-legged and flashed a spread beaver at my little sister, singing, "Ta-da!"

Lacey gawked, moving closer to inspect my lewd display. She crouched to get her face right into my pussy, so close I could feel the warmth of her breath inside my spread-open hole.

I began to tremble as I comprehended what an obscene thing I'd just done in front of my own sibling. My preteen sibling. What was worse, I was still doing it. Even worse than that, the pussy my sister stared into was the wettest it had ever been. I literally dripped onto the grass, so fantastically horny I wanted to tell Lacey to take her little fist and jam it into my hungry cunt until she couldn't see her elbow.

I got a small taste of my perverted wish when Lacey stuck a finger inside me. My teeth ground together as the digit wriggled up my chute, hunting for the missing underwear. The hunt soon became an expedition, more fingers joining the first as Lacey painstakingly studied every part of my vagina, touching and prodding her way from the pebble of my clit to the farthest depths of my love canal her fingers could reach. She was especially curious about the way my juicy hole clenched in response to her touch, and how the rougher she touched, the harder I clenched.

The vaguely devious smile on her face was what finally gave her away and gave me my holy shit moment. Lacey had spent enough time with her fingers buried inside her own slit to know how all the parts worked. This wasn't a cub's innocent curiosity; she was knowingly trying to make me come.

If I called my sister a deviant for finger-fucking me, I'd have to call myself a deviant for letting her do it. If not that, then I certainly attained deviant status when I said, "Oh yeah, that's it. R-Right— Rub right there. Oh fuck, Lacey! You're gonna make your big sister have an orgasm, honey!"

Keeping my balance became difficult. I wondered which would give out first: my quivering knees, or the tiny voice in my head screaming about how wrong this was. The voice did next to nothing to stop the pressure building steadily inside me, pleasure so thoroughly saturating my brain that I briefly forgot where we were. I came back to reality when a beam of light swept across the park. A car passed by no more than a few dozen yards away, driving along the road toward the entrance to the neighborhood. Whether or not the driver saw anything, they kept on going until the glow of their headlights disappeared from view.

The thought of being caught turned my blood into liquid nitrogen. I tried to speak but couldn't force my mouth to produce a coherent sentence. Terror took hold of my mind for all of a second before dissolving into indescribable bliss. Despite Lacey's obvious lack of experience getting someone else off, my entire frame shook as I launched into the most powerful climax I'd ever had up to that point in my life.

The devil of my little sister looked elated as she continued to work her fingers into me while I hissed swears between clenched teeth. "Oh fuck, oh my Christ! D-Don't stop! Gaaawd Lacey, holy shit...!" When I finally began to melt near the end of a long wave of painfully strong spasms, Lacey held up her fingers coated with pussy slime. As soon as my knees hit the grass, my tongue hit the center of my sister's left palm. I licked at the fingers smearing my own juices over my nose, watching through half-closed eyes as Lacey brought her other hand between her legs. "When did your mind get so dirty?" I whispered.

Lacey moaned and waited for me to finish licking her hand clean before she answered. "Doesn't it feel so good? Doing it out here?"

"Fuck, you are one filthy little exhibitionist psycho." I was shocked at the words that had just come out of my mouth, but Lacey didn't even balk, only moaning louder as she jilled off in front of me. I guided her left hand to one of my rock-hard nipples as I probed my own sopping pussy. I wanted to come again. I wanted to come, and I wanted it to be even more intense than what I'd felt only minutes earlier. More wicked thoughts arrived in droves, working me into a frenzy.

I jumped to my feet and grabbed Lacey's hand, pulling her behind me as I ran across the park. I expected a barrage of questions, but none came; she simply followed, trusting me completely. We ran to the playground equipment near the far end of the park, our footpaws kicking up the earthy scent of moist barkdust with every step. I led Lacey to the swing set and instructed her to sit down. She complied right away, squeaking when her nude ass made contact with the cold rainwater collected on the seat.

"Lacey, grab onto the chains and don't let go no matter what, okay?" When she nodded, I crouched between her spread thighs and went straight for her pussy. The first taste of her creamy slit sent a kaleidoscope of butterflies swirling inside my stomach. My nose filled with a scent so fresh and pure and lovely it made me swoon.

"Ah, ah-ahhh! Clara!"

The high-pitched whine of my name filled the air above my ears, and I looked up to see Lacey slung back in the swing seat, her arms stretched out to furry fists tightly gripping both lengths of chain. "Good girl," I murmured. Gently, I pulled apart the folds of her young sex and lapped at the slippery pink flesh inside. Her whole body twitched as I slid my tongue deeper, warm nectar trickling into my throat. I moaned into the mouthful of pussy as I felt my own juices spilling down over my ass.

Somehow, I managed to resist the urge to go all out and instead savored the taste and textures of my sister's most intimate place, keeping her perched on the brink of orgasm without sending her over the edge. She squirmed against my teasing stimulation for what felt like hours. As she stared down at me with a pleading expression, I took long licks over her clit and marveled at the galaxy spiral covering her belly, the way the pattern seemed to radiate its own light just like a real cluster of stars.

Confusion set in for a moment before I realized Lacey's fur was reflecting the shine of a nearby street light. Beyond it, a row of houses sat with their windows and porch lights all gleaming brightly. The blackout had ended.

Without the darkness concealing us, we were fully visible to anyone who might wander by. The swing set stood some distance away from the rest of the playground equipment, leaving no place to hide. I was completely out in the open, bare-ass naked in the middle of a public park, tongue-fucking my ten-year-old sister. I knew that if anyone saw us, my life would be over. A single command flashed through my mind: Run.

My tongue slashed across Lacey's clit as I lifted her butt off the seat in my hands. I licked hungrily down to the base of her tail, rimming the tight little crinkle of her asshole.

Run, you fucking idiot. RUN.

Lacey made a sound like trying to talk through gasps as I ate out her virgin cunt, the tip of my tongue no doubt plunging to depths not even her fingers had reached. My nose mashed the button of her clit. I felt her tense, and my hands slid back further under her ass as her thighs closed around my head. A whimpering cry signaled her orgasm, her pussy convulsing around the slick spear of my tongue. I purred as I slathered my face against her crotch, a mixture of spit and girl cum dribbling down my chin and neck into the valley between my tits.

RUN. NOW.

I bolted upright and collected Lacey in my arms, her body barely clinging to mine as if her limbs had been drained of strength. The mental image of strangers' eyes on us numbed my body to pain as I tore across the park faster than I knew I could run. I plowed through the trees and shrubs without breaking stride, then clambered ungracefully over the fence. With Lacey back on her feet, I pulled her by the arm as we ran across the yard between the neighbors' houses shining like stadium lights.

Only after the door slammed shut behind us did we stop, collapsing in the hallway beyond the laundry room. I slid down the wall and attacked my pussy with both hands, the wet sounds of my finger-fucking coming louder than our frantic gasps for breath. In less than a minute I was screaming, my back arching off the wall as I gushed all over the carpet. I fell over as dead weight, sweating and jittery, my hand shaking as fingers snaked deep inside my cunt to retrieve the world's most sodden pair of panties. Lacey climbed on top of me and we kissed. God, did we kiss. We kissed the way sisters shouldn't, which is how we almost always kissed from then on.

"This is—mmmh—so messed up."

Lacey answered with what sounded like muffled agreement, her tongue too busy twisting around mine to form words.

After we'd recovered an amount of stamina and gotten the house more or less in order, the two of us went upstairs and shared a long, hot shower. It felt nostalgic as we played lightly under the water, tickling and teasing, then laughed as we took turns blasting each other with the blow-dryer.

Later, up in my room, I gave Lacey her first proper lesson in cunnilingus, guiding her through the process of licking me to a wild, shuddering climax. Of course I was more than happy to return the favor, sucking her kitten clitty until she came twice. We spent the rest of the evening lying in a warm heap on my bed, talking about anything and everything—our dreams, hopes, fears, desires, fantasies. I learned nearly as much about my sister that night as I had in the first decade of her life. She fell asleep in my arms; I followed not too long after, drifting off to the gentle rhythm of her breathing.

Our relationship changed in exciting ways after that night, with Lacey and I finding a host of new ways to have fun with each other. For the remainder of the weekend, neither one of us left the house or put on a stitch of clothing. We dove head-first into our newfound exhibitionism addiction, fingering each other on the back patio in broad daylight and sixty-nining on the floor below open windows. Any perverted neighbors who invested in a telescope certainly got their money's worth that weekend, able to enjoy unobstructed views of Lacey eating every meal with a side of my breasts and both of us scarfing down pussy for dessert. By the time we went to sleep Sunday night, my little sister was well on her way to securing a future spot in the Muff Diving Hall of Fame.

Things got slightly more complicated after Mom and Dad returned home. Figuring our parents might not be thrilled to learn we'd become sisters with benefits, Lacey and I took to making return trips to the park after everyone else had fallen asleep.

When the new school year started and sleeping in until noon was no longer an option, we had to improvise yet again. That's when I volunteered to become my sister's personal tutor. The two of us spent half an hour of every school night in her room going over any homework she had, then at least another two hours doing the nasty—usually with the door left unlocked.

We also regularly encouraged our folks to take more vacations. With sparkling eyes and pouty lips, we delivered rehearsed speeches about how they both worked so hard and deserved some time to themselves. They obviously saw through our little scheme, well aware of the fact that we just wanted the house to ourselves. Had they known why we wanted to be left alone so badly, they might not have spent that week in the Bahamas. Nor would they have paid so little attention to the blurb on the local news mentioning two unidentified felines who were seen performing sex acts with a strap-on while going through the drive-thru of a McDonald's down the street.

What can I say? I got sick of cooking.
