Sibling Animosity

I fucking hate my little sister.  And no, I don’t mean the way most siblings talk about hating each other.  This isn’t about how she never shuts up about girl shit, or constantly tries to hog the TV, or pesters me whenever I’m busy — though she does all that stuff plenty.  And that shit’s annoying, sure, but none of it makes me want to push her into oncoming traffic, strangle her, drown her in the tub, or any of a dozen other ways I’ve fantasized doing her in.  And if I could guarantee everyone would believe it was an accident, I would do it in a heartbeat.  My sister is a little bitch, so at this point it would just be karma catching up to her.  But it’s like she made some blood-pact with a demon that lets her manipulate her own little corner of the universe.  And recently she decided to set her sights on making my life a living hell.

It started over the summer.  I was coming back home from a date with my girlfriend when Mom jumped me.  She wanted to know why I was not only on an age-restricted adult forum, but also sharing nude pictures of myself.  I was as confused as I was pissed off.  First, Mom has always cared more about her job than her kids, so coming home to an interrogation after a date with Amy was emotional whiplash.  Second, the part about sharing pics was bullshit.  I wasn’t a moron.  I didn’t want to get in trouble or have some rando stalking me.  I tried to tell her this, but  Mom wouldn’t listen (big surprise) and demanded to see my phone.  That’s when she somehow found the nudes Amy and I had been sharing with each other.  She claimed this was all the proof she needed to confirm her suspicions.  I was already shocked that she knew my internet history,  and was trying to figure out how she had managed to find the porn stash on my phone — remember, not a moron, so I didn’t keep that stuff in my photos app.  I barely heard Mom’s raving about how I should be ashamed of myself, and what Amy would think if she knew I looked at other girls online.

I snapped back to reality, however, when she had the balls to imply I was sharing Amy’s pics on FurHub.  That set me off.  I know I don’t have a great reputation, but there was no way I would do something like that to Amy Briar.  I had been crushing on her since middle school, not that I ever admitted it to anyone. But it meant when she asked to go out with me at the end of last year I was a giddy fool.  I tried to avoid fights at school, tried to take classes more seriously, and did everything I could to earn her trust.  You have no idea how much shit I got from my friends, telling me I was getting soft and how my girl was turning me into a pussy.  If I said it didn’t bother me I’d be lying, but I tried not to let all the heckling get to me because I told myself Amy was worth it.  And now here was Mom, accusing me of being a perv who shared pics of his girlfriend to randos online, and because she had her “proof” I knew there was no way to change her mind.

That didn’t stop me from getting into the largest shouting match we ever had.  That was when Mom let slip the source of her little intervention.  Apparently Liz had seen me on FurHub and had started to sneak on the site using Mom’s computer.   Weirdly enough, Mom only found out when some guy called her to tell her Liz was trying to proposition him.  I can only imagine how freaked out she was.  But suddenly the whole situation made a lot more sense.  Sneaky little shit had ratted me out, and probably got into my phone when I wasn’t looking at some point so she knew to tell Mom where my pics were.  I don’t know why I wasn’t more careful…I guess I assumed there wasn’t much a middle schooler could do to make my life difficult.  Boy, that was eight different kinds of wrong and stupid.

Things only went from bad to worse after that.  I was grounded for two weeks, and had both my phone and my laptop taken away.  Once I got them back, I found all my files were wiped, and that Mom had gotten someone to enable some super powerful parental controls on both devices.  I could only visit educational sites on my computer, and all my texts and emails got forwarded to my mom.  But it didn’t stop with the tech.  She started getting suspicious any time I was in a room by myself with the door closed, meaning it was doubly hard to have any kind of privacy in general, let alone chances to jack off or fool around with Amy.  Of course, all these sudden changes got Amy suspicious, not to mention annoyed.  I tried to find ways to shrug off her questions, hoping things would blow over and we could get back to the way things were.  But she wasn’t really that kind of girl.  Before school started again she finally gave me an ultimatum to come clean about what the hell was going on.  Apparently my mom had also sent Amy a cryptic text message when I first got grounded that said I would need to explain things to her myself.  Nothing like an absentee mom throwing her kid under the bus along with all the other shit she pulled.  It didn’t come as any surprise when Amy broke up with me on the spot — Mom may be a bitch, but she knew Amy wouldn’t appreciate me gawking at other girls, naked or otherwise.   Didn’t make it sting any less, or stop the lingering feeling that all my behavior just made a good excuse for dumping the guy with the nosey parent.  Like seriously, what guy doesn’t look at pictures of hot girls?  I was mad at Amy, absolutely furious at mom, but if I blamed anyone it was my brat of a sister.

Granted, it wasn’t as if Liz fared any better than me.  Her phone got confiscated the same as mine, she was banned from using Mom’s computer, and Mom’s hypervigilance encroached on her privacy as well.  The rub for me was, after moping around the house for a few days, Liz seemed unaffected by all of Mom’s overcompensation.  Mom also paid less and less attention to her, but would not let up her nagging at me about everything and anything.  I was already livid with Liz at the start; Amy leaving and Mom harassing me only added to that fire.  It was inevitable when things started to get super tense.  I mean, we never got along great, even at the best of times, but we really started to get under each other’s skin.  Well, Liz got under my skin…most of the time my futile attempts to harass her just got me in trouble with Mom.

There was one small victory I managed in all this.  Apparently Lizzie had gotten her study partner to try FurHub at some point (talk about the pot calling the kettle black), and her kid friend somehow managed to snag some super-hot boyfriend or something.  Lizzie didn’t really share any details, except that she was convinced her friend needed to share this dude, even though it sounded to me like both said friend and said dude were telling Liz to buzz off.  Hell, I wouldn’t be surprised if that guy was the one who called Mom about Liz in the first place.  Anyway, this was a rare chink in Lizzie’s armor, and I exploited it any chance I got.  I told her if this guy was so nice, then he was clearly not her type.  He probably liked cute, innocent girls more than slutty little skanks like her.  That seemed to finally sting her ego.  I doubled down on that angle as the drama ramped up.  She was too easy, she was destined to only ever pick up meatheads who were too dense to know better and dweebs who were too desperate to care, she was lucky to have a friend who was so ok with her attempts to stalk her boyfriend.  It wasn’t a substitute for getting some action with my ex, or any other girl for that matter, but it still felt pretty damn good…after all those weeks trying to go straight, it felt like slipping into a familiar pair of shoes.

These spats came to a head near the end of fall semester.  Mom had a work function to attend around the holidays, and despite her months of hyper-vigilance she felt like the two of us didn’t really need a sitter (or she was just too cheap to hire one).  This gave us the first reprieve from parental surveillance in maybe half a year.  Unfortunately we still had all our devices locked down, so the living room TV was the only real source of entertainment — not much of one, between kid’s Furflix and our small library of heavily curated video games, but it was certainly better than nothing.  I managed to snag the console first that evening, leaving Liz to find her own fun elsewhere.  It wasn’t much of a victory; Breath of the Wild was getting old, and there weren’t many other games I liked in the “Mom approved” collection.  But if it meant Liz was stuck doom-scrolling Fuzzbook then it didn’t bother me that much.

“Aiden…”

I looked up from the TV to see Liz lazing against the hallway doorframe, looking bored out of her mind.  Since coming home from school she had changed into a dark crop top and a high-cut skirt that barely hid her black panties.  Not exactly the most appropriate outfit for early winter — or her age — but it gave me some ammunition.

“Hey, nice call girl costume!”

“Gimme a turn on the TV, bro.”

 “Halloween was, like, two months ago,” I continued mashing away at my game, “or are you gonna go out and make some extra cash selling that 8th-grade tail?”

“Go to hell.”  She growled, flipping me off.

“Don’t you have a social media following?  Why don’t you chat with all those internet friends?”

“Dude, what do you think I’ve been trying to do for the past hour?  I’m so fucking bored…I need something else to do!”

“You could always do me,” I made a show of unzipping my fly.

“As if, you perv.”

“Yeah, you’re right.”  I zipped my pants up again. “I keep saying you’re too easy…I mean, just look at you.”

Normally that kind of comment would’ve sent her storming back to her room, but this time she seemed desperate enough for the TV that she was willing to take the abuse.  And that’s when she went for the sucker punch.

“God, you’re a massive dick, Aiden. No wonder Amy left you.”

“Fuck off, Liz.”

“How much did you make from selling her nudes to guys on FurHub?”

“What the hell are you talking about?”

“I just figured you must’ve really fucked up to get dumped that hard.”

“You do remember you made up that shit about me posting and selling dick pics, right?”

“Oh, yeah,” her voice was annoyingly wistful, “didn’t want Mom to go all ‘boys will be boys’ on you.  But still, didn’t expect Amy to break up with you.”

“Yeah, well I guess you don’t know Amy.”  I scowled, my attention fixed to the TV screen.

“Oh, now I’m curious.  Was she good in bed?  I guess she wasn’t, if you were looking at other girls online.”

“Shut the fuck up.”

“Oooh, so she was a good lay!  Where did you like your cock most — mouth, ass, or pussy?”

“I said shut the fuck up, you bitch!”  I bared my teeth in the angriest snarl I could make.  Liz had never pushed this angle before, and I was having none of it.  Taking the bait was my first mistake.  I thought I had actually scared her, watching her clutch her striped tail in front of her.  Then I realized she was stroking it like she usually did when she was scheming, and to my horror I noticed the realization dawning on her face.

“Wait, you never made it to home base with her, did you?  Aw, you never got to stick it in your crush after all…I mean, at least you’ve got other flings to remember, right?  Unless…”

I said nothing, but I could tell she was putting pieces together that nobody I knew ever had.  I had always talked a big sex game, but my actual experience up to that point was…well, not actually nonexistent, but close enough.  I’m not sure if even Amy knew I was still a virgin.  And I had been so close before Liz pulled her stunt.  I was just starting to get over all that shit too, but Lizzie’s inquiries were like slicing open the stitches on an old wound that was just starting to heal.

“Wow,” I could hear my sister going on, “I pulled off the ultimate blueball, huh?  Yanking your girlfriend out from under you and taking away all your porn too?  Jeez, no wonder you were being such a perv a second ago…you’re probably so needy you’d fuck a—.”

I still can’t remember if I was just trying to scare her when I threw the controller or if I was so blinded by my lust-addled rage that I couldn’t have hit her on purpose if I tried.  What I do remember was the way Liz squealed and stumbled back down the hall as the hunk of plastic shattered against the wall, inches from where her head had been.  I leapt off the couch and chased after her, barely wedging my foot in the door to Lizzie’s bedroom before she had a chance to slam it shut.  I felt her fall over as I bodied the door open.

“Hey, get out!”  Liz shouted, sprawled on the floor, giving me a prime view of her panties as I stepped inside.

“Don’t you remember the new rule?”  I pushed the door wide open.  “You aren’t allowed to close your door…you might be doing something naughty.”

“Since when did you become Mom?”

I ignored the jab.  “Since you only just figured things out, why don’t I let you in on some other secrets.  Amy was out of my league.  I never expected her to be interested in me with my reputation.”  I grabbed Liz by the front of her shirt and lifted her until we were muzzle-to-muzzle.  “And as far as I’m concerned I would’ve still had a chance with her if my slutty little sister hadn’t decided to take her away from me for kicks!”

I cannot tell you how satisfied I felt when I heard Lizzie’s voice trembling in response.  “W-what are you gonna do?”

“Well since you fucked around, you’re gonna find out.”  I shifted my grip and tugged hard on her crop top, causing her to drop to the floor, bare-chested.

“Didn’t even bother with a bra, huh?”  I quipped, throwing the wadded up shirt away while unzipping and unbuttoning my pants.  Liz stared down at the bulge in my boxers but said nothing.  I smiled, pulling down my underwear to reveal my stiffening dick.  After all the shit she had pulled, it was nice to see her intimidated into silence.  Not that I didn’t want her mouth full of something…just not sass.

“Open wide!”  I prodded her muzzle with my erection, but she kept her mouth shut until I tweaked her ear.  Her gasp of pain quickly became a gag as I thrust into her mouth.  “Didn’t get to try these holes with Amy, so I guess I’ll see which one of yours I like most.  Sound good?”

The only response was a whimpering gurgle as I started to fuck her face.  I couldn’t help but grunt in pleasure at how tight Lizzie’s maw was.  It felt amazing, especially after I shifted us so that her head was pinned against the side of her bed.  That gave me some serious leverage to work with.  It also meant she couldn’t pull away, so as much as she clawed at my thighs, the only thing she could really do was hold on tight and ride it out.

“C’mon, slut, take it!”  I said as I hilted in her throat and began a series of deep thrusts.

“Hlk!  Glk!  Mph!  Blk!  Mhh!”  She moaned in reply, tears and spit dripping down her face.  Between being pent-up and the way Lizzie’s mouth and throat were starting to milk my cock, it didn’t take long for me to reach the finish line.  With a satisfied grunt I unloaded, deepthroating my sister as she squirmed and gagged beneath me.  At that moment part of me wished I was a canine so I could knot her maw and seal all that cum in her mouth.  But the release was still euphoric, and watching all that jizz join the other fluids running down Lizzie’s face made me happier than I had been in a long time.

“How did you like your first taste of a guy?”  I pulled away and gave Liz the opportunity to cough and retch, her gag reflex finally getting the room it needed.  “Aw, it can’t be that bad.  You hurt my feelings.  Oh well, we can just move on to round 2.”  I grabbed her arm and heaved her up, bending her over the edge of the bed, butt peeking out from under her nearly useless mini skirt.

“Nice ass,” I said, slapping one of her cheeks.  Liz yelped and groaned, still recovering from my previous abuse.  Ignoring her, I flipped her skirt up so it was out of the way and grabbed the waistband of her panties.  “Let’s see if the little whore has the goods.”  Pulling down her panties revealed exactly what I expected, but I couldn’t help but drool.  Her tailhole winked at me above a pubescent slit, a web of girl juices clinging to the crotch of her panties.  “Aw, are you secretly into getting face-fucked by your pervy brother?  Well, then I bet you’ll love what we’re doing next!”  I slapped my still hard cock down below her tail, hotdogging between her cheeks to spread her girl-cum around and stiffen up in preparation for the next plunge.  Liz seemed so out of it that she didn’t put up any fight.  I was ready to change that.

Liz squealed and struggled as I started pressing my cock into her virgin pucker.  “You better relax, or this will suck even worse for you.”  I grunted, pressing her squirming body into the mattress and pushing my tip more forcefully into her slowly loosening ass.  With what felt like a pop, my dick finally slipped inside.  I rolled my hips slowly, savoring the penetration as Liz made a sound halfway between a sob and a moan.  “Aw, too ashamed to admit you like it in the ass?  Well, maybe you just need some more persuasion!”  I punctuated the last word with a powerful thrust, causing Liz to stiffen up and bawl.  Her ass started to twitch, and I could feel a dampness on my balls.  “Wait, did you just cum?”  I was unable to hide the genuine surprise in my voice, but quickly regained my composure.  “Damn, you really are too easy.  Can’t wait for the finale…but I wanna get my rocks off in this hole first.”  With that I started thrusting into her ass, my balls slapping wetly against her nether lips.

“Pl-lease,” Lizzie moaned, “m-my pussy…need…break…”

“You can have a break when I’m done with you, bitch.”  I hammered into her ass again, eliciting only a pained moan in retort.  “Good to know you’re a butt slut, though.”  I kept up the rhythm, urged on by the lewd sounds my sister was making.  The way her tailhole clenched around my cock felt fantastic.  But I felt like something was missing.  “Here, let me give you a chance to practice your blowjob technique.”  Before she could ask what I meant, Liz had two of my fingers thrust in her mouth and was sucking on them as I did her from the other end.  I could feel both my climax and hers getting close, with the way she had started to grind back in time with my thrusts.  Not wanting to leave the needy little bitch waiting, I drew back to the tip, then with a rough thrust I bottomed out.  This time she came with a gurgling moan, wetness drenching my balls as I felt her pussy spasming against them.

I let Liz flop back onto her belly, my fingers and my cock slipping from their respective holes with their own wet sounds.  Liz looked back over her shoulder with a mixture of fatigue, confusion, and neediness, clearly not expecting me to pull out so abruptly.

“W-wha?  I thought…gonna…cuminmyass…”

“Eh, I changed my mind,” I replied as I used the back of her skirt to wipe down my dick. “Decided I wanted an extra large load for the finale.”

Grabbing an arm and a hip, I rolled her over.  I looked down at her heaving chest, noting the perky nipples peeking through her fur.  Lifting her legs, I got an unobstructed view of her snatch — red and puffy, the fur around it matted with girl-cum.  I had dreamt of going down on Amy, and almost decided to do it with Liz right there, but restrained myself at the last minute.  Liz didn’t deserve special treatment.

I loomed over Lizzie, flopping my dick onto her crotch and grinding against her pussy.  She squirmed, but with her legs still held in the air there wasn’t really anything she could do.  Biting down on the side of her forepaw, Liz muttered something under her breath.

“What?”  I replied, “didn’t catch that…gotta speak up!”

“Just put it in already!”  She glared up at me, a mixture of anger and need in her eyes.

“Beg.”

“What?”

“You heard me, Liz.  Until you beg for it, this is all you’re gonna get.”

“Nuh-uh, perv, not gonn—AH!”  Liz shuddered and moaned as I pressed my cock against her clit, rubbing against her despite her protests.

“Ok, then I’ll keep doing this until you’re ready to cum, let off and watch you squirm, then start over once you’ve calmed down.”

“Y-you f-fucker…s…stop…t-teasing!”

I leaned over, Lizzie’s foot paws propped against my shoulders as I grabbed her wrists and continued my thrusts.

“I guess that’s up to you, isn’t it?”  I whispered, continuing to edge against my sister’s wet slit, her moans now inches away from my face.  I relished this feeling, especially when I made good on my threat and, as I felt her pussy start to twitch, I pulled my dick away to rest between her buns, listening as she groaned in disappointment, frustration, and desperation.

“N-no!” I could feel her hips humping the air between us in a desperate attempt for release.

“Guess you thought I was shitting you.  Well, now that you know I’m serious, you done trying to fuck a ghost and have some real cock?  Or do you just want to keep doing this dance?”

If looks could kill, Liz was giving me that death glare, but stayed silent.  Eventually her attempts at self-stimulation died down, and as my dick returned to grinding against her pussy again, she made a sound that was a cross between a growl and a moan.

“Ok, c’mon, stick it in me already!”

I continued to move, giving her a flat look.

“Aiden, please,” she whined, “I gotta cum…please let me cum!”

“You want my cock in your pussy?”

“Uh-huh!”

“Then say it.”

“Aiden, I want you inside me, please.”

“Nope, not quite.”

“Grrr! Dude, stop playing this stupid fucking game!”

“Then.  Say.  It.”

“Ugh,” she groaned, a bit lustier than I think she meant it, “big bro, little sis really needs your cock in her needy ‘coon muff.  Please, stick your teenage meat in my tight little pussy and fuck me silly!”

“Mmmm, good girl.”  I said, drawing my dick back and lining up with Lizzie’s slit, “guess I’d better reward the trash panda for being a good little whore.”  I pressed forward, relishing as Lizzie’s tight cunt gripped my shaft.  Her tongue shot out with a lusty sigh as I bottomed out in only a couple of thrusts.  I was half hoping she hadn’t popped her own cherry, but the lack of a pained response also didn’t surprise me.

“That’s right, you little bitch!”  The sticky sound of my cock sliding in and out of Lizzie’s pussy punctuated my words.  “I knew it wouldn’t take much to break that attitude of yours…just needed the right level of persistence!”  Liz squealed, arching her back as my dick slammed against her cervix.  Her legs wrapped around my waist, which made thrusting difficult, but I simply exchanged long thrusts for faster, shorter ones that caused my tip to repeatedly kiss the depths of her cunny.  And the way she moved her hips, she really wanted it too.  I leaned down, still holding her wrists against the mattress.

“So Liz, what are you?”

“Ah!  I…I’m a fuck toy, a cock warmer, I’m Aiden’s little cum dumpster!”

That did it.  I collapsed on top of my sister, pressing my cock as deep as I could, and unloaded.  Liz made the sluttiest sound so far that night, wrapping her arms and legs around me as she came hard, drenching my crotch and milking my cock.  I kept myself pressed deep, the feeling of breeding Liz overpowering any common sense I should’ve had.  Even after I was done pumping into her, I was still so hard and sensitive that my first few attempts to free myself merely caused me to thrust back inside, stirring up the contents of Lizzie’s pussy and causing her to make sounds I actually thought were pretty cute.  I was still trying as the warm fog of what I assume was afterglow took over my thoughts.

I can’t remember how long I was out, but the next thing I remember was my sister shouting in a voice that didn’t sound right.

“Hey, get out!”

I started back to reality.  I noticed that at some point I must have pulled out and was now lying on my back.  Liz was next to me, watching something on her phone…I didn’t give it much thought until I heard more familiar voices.

“W-what are you gonna do?”

“Well since you fucked around, you’re gonna find out.”

I looked up to see Liz smirking impishly.  She turned her phone to show me the screen.  The video was poorly framed, but it definitely showed me pinning Liz to the side of the bed while I fucked her muzzle.  I watched in horror as she slid the timer and I got a glimpse of our entire session in fast forward.

“Wasn’t sure you’d fall for it.”  She said, locking her phone.  “And I didn’t expect you to be so rough.  But pissing you off when you were horny worked like a charm.”

“Where the hell…?”

“My phone was on the dresser the whole time, dumbass.  I guess hate sex gives you tunnel vision.”

I couldn’t find words.  I couldn’t believe I had been played so hard by my own sister.  Seeing the disbelief etched into my face, Liz continued.

“So, here’s how this is going to work.  If I’m horny, we have sex.  If I don’t ask for something specific, you can do whatever you want.  You can be as rough as you want too, it doesn’t bother me…you’ll just have to explain to mom if you leave a mark on me.  In return, I won’t show her the video where you rape me.”

“Where I…bullshit!” anger was finally overriding my speechlessness, “you planned this all out. Hell, you even liked it!”

“Yeah, I kinda slipped up at the end, my bad.  Didn’t expect you to be hitting all the right spots.  But you know Mom, all I have to do is show her the start of that video and that’s it.  You think she isn’t above calling the cops on you?”

I was trying to find a way to counter her, some loophole she had overlooked.  But Liz had covered her bases better than I was willing to give her credit.

“Oh, don’t give me that sour look, Aiden.  Tell me you didn’t enjoy fucking your sister.”

I couldn’t.

“See?  We both get what we want…I just get some insurance that you won’t leave me hanging when I need it.  If you want you can think of it as payback for introducing me to FurHub.”

Somehow that sounded less like a concession from her and more like a flimsy consolation.

“And who knows?  Maybe eventually I’ll find someone else and won’t need you to be my pet anymore.”

I could only hope.

And that’s how it’s been.  We fuck a lot, and I’d be lying if I said I didn’t enjoy it.  Plus I get to take out my frustrations on my horny little sister.  But that’s the worst part: no matter how angry I get, no matter how rough I try to be, it doesn’t actually phase her.  She calls the shots, she’s the one with the leverage, and she knows it.  And I don’t dare make a mark on her; I don’t need an actual arrest record.  But just once I want to see her cocky little facade crack again, for real this time, and watch that arrogance give way to genuine fear.  I know better than to say something, though, or she’ll just put on a show like she did that first night.  I don’t want power play out of sympathy.  I want her to feel the way the little shits at school feel when they see me walking their way — ready to run or give me what I want.  For now, though, I’ll just have to settle for the little victories…her luck can’t last forever.
