Chapter Text
I hate my sister.
… Well, that might be a tiny bit of an exaggeration. It’s not like I despise her or anything, and I wouldn’t even say I dislike her at worst, but her mere existence borders on some of my least favorite things in life. School, work, socializing, my relationship with my parents, love, et cetera, et cetera. The list goes on. It certainly makes me feel awful connecting her to so many of my lifelong problems, but once I started lining up the dominos and took a look at things with a bird’s eye view, things suddenly started making a lot more sense. She made it hard for me to make a lot of friends in school with how bizarre her behavior was (and still is, really), and my work suffered greatly because of her constant annoyances and distractions. Our parents, sensing my distaste for her, constantly try to push us together in hopes of finally seeing us get along, but at the end of the day, we’re just two very different people, with two very different personalities. Incompatible, really. There’s nothing wrong with that, of course, most normal siblings aren’t the same person and have plenty of differences and friction between them because of it, but what we have in particular goes far beyond what I think most people would consider “normal” for siblings.
My sister is not a person that words can accurately describe. Her personality is more of a vibe of sorts, something that naturally comes to someone the moment they see her. “Ah,” they’d say, raising a dutiful finger in the air like a great ace detective who has finally cracked the case after only giving the crime scene an intuitive glance, “She’s that kind of person!” When you see her, or worse yet, interact with her, it all clicks in your head, and that’s what makes it so frustrating when people try and ask me what kind of person she is. Firstly, because I don’t like talking about my sister, but also because how do you describe that which cannot be described? It’d be like trying to describe what the color blue is or the definition of love. Oh, I have no doubt someone out there could do it, the world is full of impressive people with incredible talent, but me? I certainly can’t, and when it comes to the people I usually meet, they’re rarely able to either.
Despite her strange personality ruining much of my social life when she gets involved in it, I wouldn’t necessarily use the word “outcast” to describe her own social status, even if her odd behavior does play a large part in why she doesn’t have many friends. Outcast is typically used to describe someone who has been shunned from society by society itself. This could be for a variety of reasons, some within that person’s control, some not so much, but the general idea is that people don’t like them and place them out of the social group because of it. It’s that intent to isolate that makes my sister different from most outcasts. People want to get to know her, and they want to bring her into the fold, but nine times out of ten, she’ll dodge them in favor of coming home to study the anatomy of insects or read poetry.
There are a few reasons for this, some being an objective fact, some more so my own personal inference over the years, but the simple answer that explains most of it is that she’s just antisocial. I know for some there’s confusion with what that term actually means. Many, incorrectly, attribute antisocial as being another word for introverted. That’s not true, and really it’s far from it. Introverts are, well, for lack of a better word, pathetic creatures. They’re weak. They’re people who crave social interaction but can’t bring themselves to talk to someone or find the thought of doing so poisonous to their well-being. People who are antisocial are much worse. They don’t want to talk to people, and in fact, they don’t want to interact with people period . Most of the time this just means they’re dismissive of the social hierarchy, or whatever you want to call it, but in rare cases, they can be antagonistic, which can lead to some very negative outcomes depending on the person. Luckily, my sister doesn’t fall into the ‘despises humanity’ category of antisocial personality, otherwise, I might actually worry for her, but this personality trait of hers still causes quite a lot of friction. To her, people are a nuisance she’d like to avoid, and social interactions are a necessary evil to get through life, but that just never sat right with me.
Why? I’m the opposite. I love people. I love meeting new people and experiencing new things with them, and I especially love being around as many of them as possible. It’s one of the few things in life that really make me feel fulfilled. There’s so much joy to be had in making friends; the thought of isolating yourself from the rest of the world sounds like a nightmare to me. I want my sister to enjoy that kind of life with me, but trying to share that with someone who would rather spend her time collecting bugs and reading is like trying to pull teeth. Not to mention, once those people get close enough to her, once they feel that presence she radiates, suddenly they’re far more hesitant to hang out with me.
To make matters worse, she might hate being around other people, but she loves being around me. She obsesses over me and would spend every waking second around me if it was an option for her. I’m not really sure when it first started, and I can’t really pinpoint when it started to bug me, but I know once I started picking up on it, I suddenly felt as though a previously invisible noose around my neck had finally started to tighten. It was suffocating being around her. Every day she’d want to do something with me, whether that be reading one of her many macabre books together, watching nature documentaries she found online, playing pretend biologist in her room, or one of the many other odd hobbies she had picked up over the years. Once in a while, she’d offer to do something I like, such as doing our makeup or trying on clothes at the mall, but that was usually only when she picked up on my annoyance with her, and even that could only placate my disgust for so long before I eventually got fed up with her again.
So with that in mind, how exactly could we interact with one another normally? We’re yin and yang. She hates interacting with people, but would do anything to be in my orbit forever. I love spending time with others, but would rather blow my brains out than spend even an hour alone with her. It’s just how we were made. Again, I don’t hate her, I really can’t stress that enough. I think hate is a strong word and is ill-suited for being used to describe how I feel about my sister. She’s a good person, and she tries her best to be a good sister to me, but her existence has inadvertently led to my life becoming much worse than it ever should have been. It’s not entirely her fault, and I think that’s another thing that makes it all so frustrating to me. Once I graduated college, I’d have loved to spend the rest of my life as far away from her as possible, to get a nice apartment in Kyoto or something and never see her again, but alas, things always have a funny way of working out…
I gazed up from my laptop towards the kitchen, watching as a small black and white blob bobbed around furiously in the kitchen, racing from one end to the other, and then back to where it started. Accompanied by every sprint was a comically loud noise, sometimes a banging of pots, other times a sizzling of meat in a pan. I couldn’t really get a good look through the small window to our kitchen, but it was obvious she was struggling in there.
Clearing my throat and sitting up on the couch, I put on my big sister voice and called out, “Shiori? Do you need help?”
The sounds in the kitchen stopped momentarily, bringing with it a small feeling of relief to my ears, before a voice answered, “It’s fine, everything is fine in here. I’m just —– I haven’t made this in a while, and I’m trying to figure out the recipe again.”
I rolled my eyes at the response. “Isn’t that more reason to let me help? I’ve been making this stuff for years, why don’t you just let me take over and-”
“No!” Shiori screeched back from the kitchen, the shrill tone causing me to wince slightly. “You just relax, ok? This is meant to be a gift for you. I wanted to make something tasty on your first day back in four years, I just, uh, need — erm that… doesn’t seem right — I need some more time. Please, big sis Nerissa?”
Big sis Nerissa. I groaned silently to myself, doing my best to avoid attracting her attention with it, and settled back into the faux black leather. I hated it when she called me that. She was 18 years old, she should’ve grown out of calling me something so childish years ago. “In that case, why don’t you take a break and bring me a drink or something,” I requested, returning back to my laptop.
The simple chore had been enough to distract her momentarily. I could hear her begin to rummage around the fridge, so I expertly took the opportunity to continue writing up my manuscript, something that had been causing me a headache since the moment I arrived back home a few hours earlier.
Normally, I’d be doing this in the comfort of my cozy bed in my apartment two cities away from here, but, due to reasons that were entirely out of my control, it burned down days before my graduation while I was at a celebration with my friends, leaving only me, my laptop, and the clothes on my back unscathed. I wouldn’t have minded it so much if it had been months, maybe even weeks, before, as I easily could have found some people to crash with while I looked for a new place, but finding people on such short notice when everyone was leaving town was a much bigger problem than I had anticipated. It really only left me with two choices: Find a new place ASAP and pray it wasn’t some overpriced garbage dump, or…
“Big sis Nerissa! Here’s your drink!” Shiori beamed, extending a glass of amber liquid toward me. I closed my laptop and gently placed it aside with a small sigh. Coming back home was really the only option I had left and I was already starting to regret it. I glanced at her attire, eyeing her up casually as I took the drink from her. She was still wearing those freaky goth outfits around the house it seemed. Maybe to her, it was meant to be a sort of Gothic Lolita fashion choice, but if that was really the case, I really couldn’t tell where the cuteness was meant to come from. The chains covering her leg? The heavy-duty black combat boots? The dress that looked like it was melting off of her? The only cute part of the entire ensemble was the white bow she wore on her chest, with the rest being some ghoulish looking inky black mess. It was all only made worse by the, frankly, unappealing half-and-half style she had started to dye her hair years ago. Black and white? What, was she meant to be a mad scientist or something?
My eyes stopped at her chest. While her fashion sense hadn’t changed, I couldn’t help but wonder… Was she always this well-endowed? I guess it had been a while since I last saw her, but jeez, she’s really starting to fill out those tacky dresses. Making sure not to linger on it for too long, I flicked my eyes up to her face, immediately being met with a striking, pale orange stare looking down at me with a wide smile. I resisted the urge to shudder in response. It was always offputting how she’d stare at me after doing something I asked, assumedly waiting for my approval or validation like a puppy expecting a treat. Not to mention, she always seemed like she was bowing her head to me, looking up at me, even if she was standing directly above me like she was now. Her docile behavior at home was offputting, especially compared to how she was out in public when I wasn’t around.
I belied a small sigh. “Thanks,” I said before taking a long sip, the taste of sweet apple filling my mouth. It was freshly made apple juice, my favorite, but even then, it was difficult to enjoy with her presence looming over me like it was. I needed to break this tension. “So…” I awkwardly began, averting my eyes from her for the time being, “Where are mom and dad anyway? They said they’d be here when I came back, but I haven’t seen them all night so far. If they were shopping I figured they would’ve been back by now.”
Shiori cocked her head, blinking a few times before placing a finger on her chin. “What do you mean? Did they not tell you?”
“Tell me what?” I cautiously replied, turning my head and raising my brow at her.
“Ehh, they really didn’t, did they?” Shiori giggled quietly to herself. Raising a hand, she pointed at the landline hanging on the wall. “Auntie Bijou called a few hours before you arrived and asked if they could drive over to her place to pick up some things she was going to donate to you after she heard your place burned down.”
My eyes narrowed slightly. Bijou was in Yokohama, and we lived in Okayama. That was, at the very least, an eight-hour drive assuming traffic was decent. There was no way they’d be home later tonight with a drive like that. A nervous bead of sweat began to travel down the side of my face, a feeling of dread quietly taking hold of me. “So… what, they’re coming back tomorrow evening?”
Shiori shook her head. “They said they were going to spend some time with her while they were there since it’s such a long drive.”
Oh fuck. “... How long?”
Bringing a small hand to her face, she quietly mumbled to herself as she began to count on her fingers. “Let’s see… I think they said… three days? Not counting the day they’d be coming back, so I guess three and a half?” She grinned, baring her sharp fangs at me with a wide smile. “I really thought they told you, but I guess they can be pretty forgetful sometimes, huh?”
Three. Whole. Days? I felt my spirit sink deep into the recesses of my body, locking itself inside and throwing away the key. They really left me alone with her for three days? How could they forget to tell me something that important before I showed up? Did they seriously just forget? I silently clicked my tongue as realization struck me. No, knowing mom, she probably didn’t tell me on purpose. No doubt she knew I wouldn’t show up if she did. Shrewd bitch… She was right on the money too.
I pouted my lips, trying to decide what to do next. Leaving seemed like the best option, but given that I was currently trying to stay on my parent’s good side, what with my home being charred rubble right now, it would probably only hurt me in the long run. If I had to stay here with her, then maybe the best option was to have a little bit of fun with it. My own kind of fun. Starting with that ugly dress she was wearing.
Smiling to myself, I moved to place the glass of juice on the coffee table behind Shiori. However, as I passed by her, I pretended to catch myself on something and sent the drink tumbling all over her dress with a splash. “Oops!” I sneered, holding myself back from bursting into outright laughter. A simple gag to start, nothing harmful of course, just something to throw her off a little. She absolutely adored that freakish fit, so having to clean it was bound to make her upset for the rest of the night.
Shiori looked down at the stain, eyes wide though with the smile still wide on her face. Her eyes fixated on it for a brief few seconds, examining and looking over it curiously, before turning her attention back to me. “Are you ok?” she gently asked, taking the glass from my hand. “I bet your legs were starting to get numb after laying there for so long, happens to me a lot while reading, haha. Want me to get you a refill?”
Right. I had completely forgotten. Even bullying like this rolled off of her as easily as juice did on a leather dress. Defeated, I fell back onto the couch, folding my arms under my chest and rolling my eyes. “Yeah, sure, whatever. Just take all that off and throw it in the wash so you’re not dripping all over the place.”
“Sure thing!” her cheery voice responded. I heard her footsteps on the soft carpet begin to turn and walk away from me, this time towards the hallway rather than the kitchen. My eyes stayed fixated on the black leather of the couch, unable to bring myself to do anything but sulk while I waited for her to come back. It was always so annoying dealing with her. Why couldn’t she be a normal sister? Someone who would freak out at me after a cruel prank, maybe even punch me for it, at least something other than annoy me with her constant doting when I was clearly trying to get a rise out of her. I pressed my forehead against the couch and sighed. A short time later I heard those small steps approach me from behind, complimented with the sound of light clinking in a glass. “Here you go, big sis Nerissa!”
I shifted my weight to face her, sitting upright on the couch and raising my hand. “Thanks again for the-” I stopped as my eyes adjusted to the bizarre sight in front of me. Standing there was Shiori, the same Shiori I had seen a minute ago, but instead of changing out into another outfit like I thought she would, she was… Well…
She was completely naked.
Stunned, I blinked a few times, trying to regain my senses before taking the drink from her waiting hand, continuing to look up at her with a perplexed look on my face. She looked down at me with that same smile she always wore after doing what I asked, her large breasts dangling particularly close to my face now that the dress wasn’t there to support them. I gulped, the blood in my body rushing to my crotch as I gawked at them, causing a slightly noticeable bulge in my pants.
A joke? Was this a joke? Did she know I was trying to mess with her before and wanted to fuck with me? It was unlikely, she wasn’t really the type for humor, but maybe instead this was her attempt at trying to get closer to me? Either way, it left me at a complete loss for words. “Aha… Ahah, wow, uh, alright, I’ll bite I guess, why… are you naked?” I awkwardly asked, averting my eyes from her ghostly pink nipples.
She tilted her head, her expression almost as puzzled as mine was. “What do you mean? You told me to take it all off, so I did. Did I do something wrong?”
This girl. Ohhh, I hated this girl. I could feel my cheeks start to turn a light red, my pulse quickening even in spite of my best efforts to keep my eyes off of her. Christ, what was wrong with me? I had seen her naked a million times before this. Why was I getting so flustered now? “That’s… I…” I couldn’t even process what to do about this strange turn of events. My mind felt like it was racing a million miles a minute, and my mouth was being lapped like it had a flat tire while it tried to spit something out. “... That’s a ridiculous thing to say. Are you really saying you’d strip naked for me just because I told you to do it?”
“Yeah, of course! I’d do anything to make my big sis happy!” Shiori laughed, putting her hands behind her and leaning closer to me. I watched her breasts gently sway above me, both coming dangerously close to my face, and I could feel the heat in my cheeks getting worse by the second.
My embarrassment however quickly gave way to annoyance. I was already getting sick of looking at her curvy figure and if those tits got any closer to my face I’d probably snap. Really, I wanted to yell at her to put something on already, however, a more sinister idea began to brew inside of me. If she insisted on being this childish, then perhaps I’d indulge her a bit. “Oh? Anything to make me happy, is that right? Then why don’t you make your big sis happy and go open the balcony curtains for me?” I smirked, gesturing over to the sliding door. Two could play at this game.
“Sure!” she chipperly replied. Without skipping a beat, she turned on her heel and made her way to the balcony door, sliding open the curtains. Darkness had already covered the city, the bright moonlight completely enveloped by the cloudy night sky. She turned back to face me, her pale figure and thin smile making me twitch down below. “It’s pretty out tonight, isn’t it? Even though it’s pitch black out, the city still seems so bright! I love how it looks from up here.”
Uh-huh, whatever. I barely listened to what she had to say, instead sitting up on the couch and motioning her to open the door. “It’s kinda stuffy in here, why don’t you let in some air?”
Again, without hesitating, she flung open the sliding door, letting in a cool blast of night air into the apartment. I shivered, not realizing just how chilly it had gotten while I was settling into my warm and cozy couch, and looked up at Shiori to see how she was doing. She had goosebumps all over her body, but otherwise seemed unperturbed by the sudden shift in temperature, glancing back at me with her wide eyes. “Is that good enough for you, big sis Nerissa?”
“Y-Yeah,” I replied, wrapping my arms around myself in an attempt to keep some of my warmth away from the nipping gusts of wind. Dammit, this wasn’t working at all. At this rate, I was only working to make my morning worse by giving myself a cold. Did she even care she was standing in front of an open window completely naked? Sure we were on the 7th floor, and given how dark it was, there wasn’t much chance of anyone seeing her from up here, but the complete lack of shame on her part was really starting to piss me off. I stood up, pointing my slim finger at her, and accusedly asked, “Aren’t you cold?”
Her eyes glanced down, mine following with, and we both noticed that her nipples had already started to stiffen in the cold, their once soft pink appearance shifting into a harder, more perky look. “Mmm… I guess, but it’s not really a big deal to me! My body has always been naturally resistant to the cold. Though, by the looks of it, my nipples would probably disagree, haha!” My crotch twitched, the bulge in my pants growing larger as I continued to look at her. Now that her enormous tits weren’t hanging over my face, I was finally able to take in the rest of her body, and I was starting to realize just how well she had developed during my four year absence.
Of course, her breasts were a lot bigger, but her ass and hips also looked far larger than I remembered them being. It was a miracle she fit it in such a tight looking dress come to think. I ran a self-conscious hand over my own bust and butt, a tiny bit of jealousy welling up inside of me as I compared the two of us. It’s not as though I didn’t have a nice figure myself, I worked very hard to maintain my image and I was gifted with fairly good proportions, but, compared to her, I may as well have been born with no tits and a flat ass. I was slimmer, maybe, but she was thick in all the right places. My body started to feel hotter. Why was she so damn pretty? So… stupidly fucking sexy? If she wasn’t so opposed to people, she could fuck any guy she wanted to.
My eyes fell to her crotch, the baldness catching me off guard. She was shaving down there too? Not just trimming it either, but cutting it clean ? I raised a finger to my lips, biting down on it softly, a feeling of anger flaring up from somewhere inside of me. Wait, does that mean she actually was having sex? Why else would she shave down there? Fuck, was it just another weird quirk of hers? From between her thick thighs, I could see the lips of her pussy barely poking out, taunting and inviting me to come closer.
Again, my crotch stirred, and I could feel my pants begin to tighten. I was raging now, and even sitting it was becoming hard to conceal it. My head felt light, and my breaths were uneven. I couldn’t remember the last time I had felt this turned on. Wait, turned on? No, no surely I wasn’t actually getting turned on, especially not by someone as annoying and repulsive as she was. She was my sister for Christ’s sake! I stood up, trying to hide the erect cock that had been steadily growing throughout the night. “Shiori?...” I suddenly asked.
“Yes?”
My mouth dried up, the words I wanted to say catching in my throat. This was a really bad idea. Like, a really really bad idea, and I knew it was, but… “You’d do anything I told you to do, right? No questions asked?”
She paused for a moment. Her face told me she wasn’t really considering what I was saying, she already had an answer ready for that, but was rather trying to determine something else. Whatever it was, it didn’t take long before she finally figured it out. “Yep! Anything at all. I want to make you happy, so no matter what you ask me to do, I’ll definitely do it!”
I had expected that response, and in fact, I had counted on her saying those words exactly. “What if…” I paused, feeling my heart try and rip itself out of my chest. Oh god, what was I about to say? “What if… I told you to suck my cock then? Would you do it?” Silence hung in the air like a heavy weight on my shoulders, my body pleading with me to throw in a “Just kidding!~” before it was too late. Why the fuck would I ask something like that? What was I hoping to accomplish with it?
Shiori stared at me, obviously taken aback by the question, but what struck me as odd was her lack of disgust. No, in fact, she seemed to almost perk up in excitement, the smile on her face widening as her eyes lit up. “I could do that for you big sis! Did you mean right now?”
I blinked. Did I? “... Yes.”
A moment passed and I suddenly watched as she made her way over to me. Her stride was wide and her steps light, barely making a sound as she glided across the carpet to me in what couldn’t have been more than a few steps. I felt hands tug at my pants, the fabric crumpling around my ankles soon after, before a set of lips curled themselves around my member, taking it all in at once. My vision quickly twisted, overwhelming pleasure taking over my senses and causing me to almost stumble backward. She had been so fast. So quick. It was like she had been waiting for me to ask her since the moment she came back with my drink. Did she think I told her to strip so we could do this in the first place? I couldn’t even begin to process what a person like herself would be thinking, especially during a time like this.
She began to loudly suck my dick, pressing her nose against my lightly trimmed pubes before pulling back, the sounds echoing against the plain white walls of the apartment. I could feel myself already close to a climax. She had only bobbed her head on my crotch for a few seconds, but the way she expertly worked my shaft with her tongue made it feel like hours. Her tongue curled and wrapped itself eagerly around my cock, its warm sensation making my tip tingle in delight, with the rest of it melting away inside of her hot wet mouth.
Black strands of hair fell in front of my eyes, and I weakly tried to push them out of the way, lasting only a few seconds on my own two feet before I needed the support of the couch again. Fuck. Fuck, she was really good. I had had my fair share of blowjobs in college, but she — my own sister! — was definitely taking the cake right now. My eyes fixated on her head, watching as she effortlessly took in every inch of my cock, wrapping her fingers around my hips to steady herself and keep a decent pace. With her on her knees, I could see just how round her ass was, every bob of her head causing her hips and ass to wiggle beneath her, the sight making my already rock hard cock twitch harder between her lips.
Her sparkling pale eyes looked up at me, obviously asking for affirmation that she was doing a good job. Fucking moron, how did she expect me to respond during something like this? Did she even understand the kind of situation we were in right now? Beads of sweat beat down my brow and my legs continued to wobble beneath me. Still, her eyes continued to stare at me, watching, waiting, expecting. My lips parted, breathy moans the only thing that could escape me for a few seconds before I finally whimpered, “Y-You’re doing… a great job… Shiori…”
My words seemed to have a positive effect on her, as she drastically picked up the pace, turning away from me as she focused entirely on sucking me off. Her black and white hair looked like a blur beneath me, my mind barely able to focus on anything aside from the sensation of her lips on my dick. Her pale skin had turned a slight tint of red, either from the cold or from her efforts to make me cum, and her fingers dug even harder into my skin, my mind ignoring the pain as it focused entirely on the pleasure.
Without saying anything, my hands gripped her hair tightly, yanking it in rhythm with her movements, my knuckles turning a bright hot white as I hung on to her for dear life. I could feel my dick burning inside her mouth. I wanted to cum. I needed to cum. I bit down hard on my lip, the cherry red lipstick I had put on earlier in the morning filling my mouth with a disgusting waxy taste. I brought her head down hard on my cock, forcing it as far back into her throat as it could possibly go, and kept her in place, my eyes feasting on her delicate-looking figure as it wriggled underneath me. She gagged at first, the vibrations of her coughs tickling my dick and making me shiver, before eventually settling down, letting me lead as I began to throat fuck her with as much strength as I could muster.
Fuck. Her mouth felt nice when she was using it, but it felt incredible when she let me have it. There was no resistance from her, every thrust I made, every pounding of my stomach against her face, every yank of her hair, all of it was taken like it didn’t bother her. It was intoxicating. So much different from the frat boys or sorority girls that I’d fuck. She wasn’t just agreeing to have sex with me, she was agreeing to let me own her body. I wanted to use it all night if I could, have her blow me nonstop until I was satisfied, but it only took a few more seconds before it finally hit me.
I hunched over, gasping loudly as the pressure in my crotch reached its climax, pulling her in as deep as I could. I waited, my dick twitching over and over inside her warm mouth, holding back the floodgates for as long as I could before finally letting it all release at once, shooting a load straight down her throat. Below, I could hear the sound of her choking, no doubt the load of hot cum taking her by surprise, but soon she began to eagerly suck it down, the sounds of her lips making the guilt in my stomach solidify while I continued to hold her head.
Her tongue swirled around my dick, the force of her suction making me gasp and release my grip on her. She pulled away from me with a smile, the trail of spit and cum on her lips making me lick my own lips as I imagined what she must have tasted like at that moment. With one triumphant gulp! she swallowed the mess I’d created in her mouth, sticking her tongue out to show off her handiwork to me. “Ahhh!~” her playful voice rang out, “All clean!~”
I gazed down at her, unsure of what to say, but knowing that I had fucked up beyond belief. What was wrong with me? Cumming in my own sister’s mouth? It still all felt like a dream to me, a terrible, awful, nightmare, but even worse than that, it felt like pure sin. A sin that I wouldn’t be able to cleanse myself of for another 500 years no matter how hard I prayed and begged for forgiveness. I felt disgusted, terrible that I had let it all happen, and not only that, I asked for it to happen.
And, even in spite of all that, I still found myself wanting more.
I gripped Shiori by the arm. “Follow me,” I commanded, lifting her to her feet and dragging her to the balcony. If I was destined to go to hell, if this really was the end for me, then there was no point in holding back now. Even with the warmth from the hot blood pumping through me like crazy, the cold night air still clung to my saliva drenched cock like a claw, stinging it with a chilled wind that caused me to shiver. I flung her against the parapet, pressing her nude body against it and bending her over the edge. “How many people do you see down there?” I asked while pressing my dick between her legs.
I watched as the joy that had been plastered on her face all night faded into a neutral stare, every last bit of excitement in her vanishing in an instant. “Ten or eleven I guess,” her monotone voice responded. I grinned. We were about 7 stories up from the ground, and considering how dark it was, it would’ve been near impossible to see Shiori from down below. My dick pushed against the entrance to her pussy. We had neighbors, and if we were especially unlucky, someone might come out on their balcony during what was about to happen, but things were usually quiet around this time. If we kept our voices low, we could definitely get away with it. I smiled to myself at the thought. Then again, if someone caught a peek of her like this, well, that wouldn’t be so bad would it? Exposure to people from time to time was a good thing for someone like her.
I began teasing my cock against her lips, feeling how slick they were already for me. Her body shivered underneath me, clearly not expecting the sudden wave of pleasure that had just shot through her, and she craned her neck to look back at me with an excited grin. “Did you want to stick it in me, bis sis Nerissa?” she asked as she began grinding her hips against me. I felt the warmth of her pussy press harder into my already sensitive dick, causing me to breathe in a sharp gasp, the autumn air rushing down my throat and sticking to my lungs.
Quickly collecting myself, I gripped her hard by the shoulder, pulling her ear close to my lips. “That’s right. Big sis wants to fuck you. Now be a good girl and lean over the balcony as far as you can.” There were no objections from Shiori, she simply nodded at me and heaved herself over the balcony, just far enough to expose her chest over the parapet edge, gripping onto it tightly in anticipation of what came next. Her ass wiggled expectantly in front of me, begging me to come closer and have my way with it.
This time, I didn’t second guess myself. I pushed my full length into her, feeling the warm embrace wrap tightly around me, my knees immediately giving out from underneath me as my hands shot forward to keep myself upright. She was incredibly tight. For someone that wasn’t afraid to act like a whore, she certainly had the body of a young virgin. As though sensing my enjoyment, I could feel her squeeze tighter around my cock, a loud moan immediately slipping out from my lips. Fuck, I hope nobody heard that.
My dick began sliding deep inside of her, slowly to start, letting it acclimate to the feeling of her insides, taking in every inch of her and how she felt against my member. I could feel my heartrate skyrocket in my chest, the blood in my veins coursing through me at a million miles per minute. It felt so wrong being balls deep in her like this, but fuck, she felt so goddamn good. That perfect body I had been so annoyed with minutes earlier was now my own personal fleshlight. Her fucked up personality, the one I had grown to hate over the years, finally felt like god’s gift to me, a blessing to me and only me. My hips began to pump her with my stiff cock, pulling back and slamming into her as hard as I could, enjoying every wave of ecstasy that rippled through me.
This hopeless fucking girl. This freaky bitch. This stupid dumb whore . I gripped her ass tightly, squeezing down on it with my fingers, her tiny mouth letting out a weak moan into the night air. “Heeey!~ Shiori? Look down at all those people… don’t you feel embarrassed showing off your gigantic rack to them like this? All while getting fucked by your cute and adoring big sister?~”
I watched the light in her eyes die in response to the question, her listless gaze peering down into the brightly lit city street below. “It’s whatever. I guess,” she coldly answered, the sound of my hips hitting her tight ass almost drowning her out completely.
For whatever reason, the deadpan reaction made me ecstatic, the lifeless look on her barely illuminated face causing my cock to twitch in delight. I picked up my pace, my wobbling legs hitting the patio furniture as they tried desperately to find a steady grip on the floor. “Wooow so you don’t even care you’re getting railed by your big sister in front of strangers? What if they see you? What if someone recognizes you? You’re not worried?~” I continued to tease, trailing a finger down her sweaty back.
“No, not really.” Her voice was dead, completely monotone, the words almost sounding like they had come from a corpse. A contemptuous smile flashed across my face. She was always like this, always looking down on people in life. The only person she ever looked up to was me. Me and only me alone. No other person mattered in her fucked up life, and for the first time in my entire life, that felt good . My cock throbbed inside of her, her walls wrapping themselves even tighter around my dick.
Leaning over her, I began gently nibbling on her ear, watching as life sprang back up inside of her, the breeze pushing away the bangs covering her gleaming eyes. “You’re right. Who cares? It’s just me and you up here. The two of us. Let’s focus on that. That reminds me, do you want me to tell you something special, Shiori? Something I’ve never told you before?”
She nodded enthusiastically, her tight lipped smile stretching wide across her face.
I inched closer to her, stopping my thrusts momentarily as my lips pressed against her ear, the breathless words touching her red ears as I whispered, “I love you, Shiori.” As a lie, it was sickly sweet like honey, the hint of belittlement trapped inside betraying my words just enough to help me feel better about saying it, but not enough to let her catch on. I continued my performance, “As long as you continue doing what I say… I think I might wind up sticking around a lot longer this time. Ah! No promises though… It depends on how much I enjoy my time with you.”
To anyone else, it would’ve been obvious what I was doing. What I actually meant with what I said. But to her? The look on her face told me everything I needed to know. She was completely wrapped around my finger, her infatuation with me clear as day on her reddened face. She bit down hard on her bottom lip, her fingers curling around the parapet tightly, and I could feel the heat from her pussy grow. Her entire body was starting to glow a bright red, those piercing eyes excitedly looking back at me. She wanted it more than ever. A chance to prove she was worth staying for. I sneered quietly at her, peeling myself off her back.
Continuing with what I started, I began fucking her harder and faster than I had before, watching as she braced herself to take it. All I could think about was filling her with my cum, exploding deep inside of her with everything I had. I wanted her insides stained with my seed. It’s all that mattered, all that I could focus on. I tore off my shirt, my breasts quickly falling victim to the cold wind, the sweat covering them feeling like tiny icicles against my skin once the chill took over. Still, I continued to pump my dick inside of her, quickening my pace, letting my cock ram her with as much force as I could manage. The sound of our skin slapping together carried through the night air, every exhausted breath and moan disappearing into the inky darkness around us.
I continued to push harder, ignoring the feeling of exhaustion starting to take over my body. My cock felt like it was moments away from climax already, even after blowing my load in her mouth. Her cushiony thighs and rear enveloped my hips and legs, each push into her almost feeling like I was fucking a pillow, my mouth hanging open while the pressure in my crotch continued to build up, threatening to release itself any second. There wasn’t long — I could feel myself at my limit. My head craned itself to get a better look at Shiori, expecting to see a wild grin on her face, but instead finding a pensive stare, her eyes cast on the ground once again.
Puzzled, I slowed down, asking, “Something wrong?”
“Cop.”
My eyes widened and I leaned over her shoulder, my cock still buried deep between her thighs. Sure enough, in the bright spotlight of the street lamp was a lone police officer, digging around his belt for something. I squinted, watching him produce a long, black object, fiddling with it briefly before flicking it on, a beam of light springing forth from it. I began to panic. He wasn’t aiming that up at us, was he? As soon as the thought crossed my mind, I watched him angle the flashlight up, the beam quickly making its way to our floor. Without thinking, I hooked my arms under Shiori’s and yanked her backward, the two of us falling to the floor with an explosive thud.
The light barely missed us, brushing over our balcony and hanging there for a few seconds, until it finally retreated back down to the streets below, leaving us both sprawled across the floor. I shut my eyes tightly, heavy pants escaping from me as I attempted to catch my breath. Christ, that was too close. As I was about to breathe a sigh of relief, I felt a tingling sensation from my crotch, followed by mind-numbing pleasure as a familiar set of wet lips lowered themselves onto me. Opening my eyes, I looked down to see Shiori’s face nearly pressed against mine, her wide eyes staring directly at me.
I could feel her hips start to slam down on mine, her pussy working my cock with all the force I was giving her before and more. “Ahh… Ahh, s-shit!” I began to moan, propping myself up on my shoulders. Her hand pressed itself against my chest, firmly pushing me back down, and she straightened up on top of me, lifting my hands to her breasts. Her skin was cold, but I could feel the warmth buried beneath it, and as I squeezed my fingers down on them, I could feel that heat begin to radiate on my palms. She continued to stare at me wordlessly, her head angled down so her eyes could look up at me, and I took in her ethereal eyes as they peered out at me from the shadows shrouding her features.
Her entire body felt almost unearthly as it bounced up and down on top of me, my eyes unable to take themselves off of her pale skin and curvy figure for longer than a second. I squeezed down harder on her breasts, watching as her body shivered in response, a wave of happiness crashing into her as she relished my touch, hoping and waiting for more. I gave her what she wanted. My hands fondled her chest, squeezing them hard while my thumbs teased her nipples. Her lips parted, and I could hear her begin to moan loudly, the lewd noises causing me to redouble my efforts in an attempt to squeeze more out of her.
She slammed her hips down, wiggling on top of me. I was so close. So fucking close. My eyes stayed locked with hers, and I could tell she was waiting for it, inviting me to finish for her. I took a deep breath, exhaling steam into the night air. With one final push, I released everything I had left for her, filling her tight cunt with every ounce of cum left in my balls, every spurt of my dick sending more hot liquid rushing inside of her. I froze as it continued to pour out of me, my vision becoming a starry blur as I felt bliss take me over. Above me I could feel her press down on me as hard as she could, keeping my dick inside of her as she took it all, milking my cock of every last drop it could. Her ass felt so soft against my thighs. I wanted to feel it as well, but I couldn’t find the strength in me to do it. The sounds of my pitiful moans continued to grow louder, my breath staggering as I attempted to keep myself quiet, though to no avail.
And then it was all over. One final throb and the last of my cum leaked out inside of her, followed by complete stillness from the both of us. The tension in my body was released, and I could feel everything . The sound of my heartbeat filling my ears, the sweat cascading down my tired body, how heavy each and every one of my limbs felt. Shiori herself, the oddly lightweight girl she was, felt like a lead block sitting on me, her lingering presence making me give a weak moan.
Sensing my discomfort, Shiori giggled and lifted herself off my lap, laying down next to me and wrapping her arms around me, nuzzling her cheek against my chest. Her innocent eyes looked up at me. “Did I do a good job big sis Nerissa? You’ll stick around now, won’t you? I’ll go as many times as you want! I could do this all day if you wanted me to! Just stay with me pretty pleeease!~” she begged, resting her chin on me.
I could barely bring myself to look at her. My stamina was completely drained, and my thoughts were scattered, but with some effort, I lazily swung my head in her direction. Her expression was offputting, to say the least, the obsession in her soul practically reaching out for me from behind her glassy eyes. I closed my own eyes and took in a deep breath. “Before any of that… Let's go get cleaned up.”
I plopped onto the sofa in my nightgown, exhaustion still aching in every muscle of my body as I took a swig of the juice I had left on the table. Even though it had warmed up since its initial delivery, it was somehow still incredibly refreshing after a nice hot bath, especially considering the circumstances before that. “What a night…” I quietly mumbled to myself. Never in a million years would I have expected things to play out like they had. I still couldn’t quite fathom why I had done what I did, or what exactly had driven me to do it. In the bath I had gone through it over and over, replaying the scenes leading up to it, the scenes during, and the aftermath on repeat until I had come to a conclusion, and still, I couldn’t pinpoint an answer. None of it made sense.
A soft set of arms suddenly wrapped themselves around me, Shiori’s head gently pressing itself against my stomach. “Ahh you smell just like me, big sis Nerissa!” she laughed, resting her head on my lap before continuing, “Thanks for taking a bath with me, it’s been ages since we’ve done something like that together! It was kinda nostalgic… We should do it more often! Ohh that reminds me, you probably don’t know this since you’ve been gone, but mom let me start collecting insects. Dad was totally against it, but I promised I wouldn’t make a mess like last time. Plus, I really thought you’d want to see them when you got back from college. They’re really cool, and I have so many of them! I’ve actually been learning a lot about insects lately. For example, did you know a male ant’s only purpose is to defend the colony and mate? I think that’s so interesting! They all live their lives just for their queen, every single one of them willing to die at a moment’s notice so that she can live another day. It really makes you think…”
I chose to ignore her comments. There were more pressing issues in my mind that I wanted her to address. “About what just happened… Why did you agree to all of that?”
“Eh? What do you mean? I told you, I’d do anything for you big sis Nerissa,” she replied, gazing up at me from my lap.
There was a pang of annoyance somewhere inside of me, her simple and straightforward answer pissing me off immensely. I looked down at her with narrowed eyes. “Why?”
“Why?” she confusedly asked, “What do you mean why?”
More annoyance began to rise. “What do I mean?!” My hand clenched into a tight fist, trembling as I tried to cool myself off before continuing, “It should be obvious what I mean. Why do you want to do so much for me? I don’t understand it, no normal sister would go to such lengths just to please her older sister, so why do you?” I could feel my top lip curl in disgust as I continued to look at her.
She gazed at me with a look of uncertainty, seemingly unable to process what it was I was trying to say. She cocked her head once to the side, then to the other, blinking a few times before a look of realization dawned on her face, finally reaching the conclusion she thought I was looking for. “Ah! I get it now! It’s 'cause I didn’t say it earlier, right?” I felt her weight on my lap shift, and suddenly her lips were pressed against mine, her hand slowly caressing my cheek as she began to kiss me, stunning me where I sat. Her lips were soft, almost velvety, and I could still feel the warmth of the bath clinging to her silky smooth skin as she wrapped her arms around my neck. Silky hair brushed against my cheeks, the distinct smell of lavender floating around my nose causing me to instinctively take a deep breath, filling my lungs with the wonderful scent. She slowly pulled away, trailing her black nails down my neck before whispering, “Because, big sis Nerissa, I love you too. I love you more than I love anyone else in the entire world, and if that means you want my body, or even my eternal soul, I’ll gladly give it all to you if it makes you happy.~”
I was speechless. Between the words she spoke with so much meaning towards me and that kiss that conveyed everything else, I felt like I had unleashed Pandora’s Box with my careless actions. Whatever I had thought our relationship was before was completely shattered, thrown away, and buried for good, replaced instead with something I both feared and craved. I gulped, running my fingers across my neck. Even with that fear in my heart, though, I still felt compelled to ask, “… And that means you’ll do… whatever I want? Whatever I tell you to do, you’ll do it?”
She nodded enthusiastically like a wide-eyed puppy, wrapping her arms tightly around my neck. “Whatever you want.”
“No matter what?”
“No matter what.”
“Anything at all?”
She licked her lips, my dick twitching in response as it recalled the feeling of her mouth. “Anything.”
I leaned in closer, brushing my lips against hers, daring myself to get closer. They had tasted so good the first time. Just one more taste couldn’t hurt. My cock twitched again as our lips collided, and I began to shift my hips underneath her, spreading her legs out so her crotch rested on mine. I pulled away, panting heavily. She stared at me expectantly, waiting for more. Just one more time. We kissed again, this time harder than before, and I couldn’t resist biting down on her sultry lips, pulling them back with my teeth before releasing them. We collided below, our nightgowns parting to allow my stiff cock to grind against her wet pussy, both of us moaning in unison. One more. Just, one more. I needed one more. I couldn’t stop myself from kissing her again, passionately running a hand through her hair, letting my desire take me over completely. I pulled away from her one final time and whispered, “Then… can we do it again?”
She grinned, eyes widening as she pressed her chest against mine. “As many times as you want, bis sis Nerissa. I’ll stay with you like this for as long as it takes. Use me until you’re completely satisfied, ‘kay?”
I shuddered.
How could I ever resist an offer like that?
