You had always hated your older sister Lalisa. She had constantly hogged your parents' and peers' attention, gorging herself on their praise while your own achievements had been duly ignored; and of course, she had been an unrepentant slut. It was a rare night that your sleep had not been uninterrupted by the sounds of Lisa fucking some lover of any gender, her bed creaking so badly she required a new one every year, how she managed to remain unimpregnated was beyond you. Naturally, growing up with such a whore of a sister had caused you to follow the complete opposite path, so while she had ascended to sex-drenched idol-hood, you had instead quietly completed school and gotten yourself a pure and sweet girlfriend. Not that you had done anything yet. Sex before marriage? Appalling! Public displays of affection? Disgusting! Mutual Masturbation? Nauseating! Hand holding, fingers locked? Perverse! Only the chastest of kisses, and wholesome hugs were allowable, and it brought you no small amount of joy that she wholeheartedly agreed with you. So it infuriated you to no end that you were unable to bring her along with you on yet another family vacation to some tropical retreat, no doubt your parents were overly worried about how she would react to your harlot of a sister, but you looked forward to seeing her again. You just had to make it through dealing with whatever mindless debaucheries your big sister Lisa had cooked up for this trip...

Awareness comes slowly to you, reality slowly bleeding into your dreams as you gradually become aware of your surroundings, your nerves tingling as they lazily report upon the myriad sensations assaulting them. The exquisite softness of the sheets encasing you, the gentle cold air of the AC caressing your face, the burning sensitivity of your staggering erection digging into the mattress, and the strange patch of warmth in the bed beside you. You start, flinching away from the person curled up mere inches from you, scooting to the edge of the mattress as they groan softly in protest. Lisa blearily raises her head up from her pillow, squinting at you in confusion before collapsing back onto it and letting out an indignant whine, wriggling to find a comfortable position before falling back asleep. Your heart hammering, you slip carefully out of bed, doing your best not to disturb your sister, all the while cursing your parents for forcing you to share a room with her, this was certainly not helping you two bond. The fact that there was only bed was a further annoyance, it was a huge one to be sure, but Lisa seemed to unconsciously seek out heat in her sleep and latch onto her target like a leech, so in reality you ended up far closer together than you would have liked. Which made dealing with your morning wood all the more awkward, since you were loath to masturbate, your member tended towards truly spectacular erections come the dawn, urging you to give in to your vile thoughts and pleasure it. Ignoring your disgustingly drooling penis was difficult at the best of times, but with the scent of a woman in your nostrils, no matter that she was your sister, made resisting your wicked meat nearly unbearable. Every morning you would cover it in an ice-cold washcloth, but even then it would defiantly stand strong for many minutes before ungraciously retreating. Needless to say, your testicles were in constant agony.

After dealing with your unwanted visitor, you check your phone, lovingly responding to your girlfriend's messages before learning that your parents once again had skipped off on some early morning jaunt and would only be back by evening. So, yet another day you would have to spend solely in the company of your whore sister, wonderfully. Though, to be fair to Lisa, you had yet to see her engage in her usual wanton behaviour, you did not doubt for a moment that she had been busy messing around while you were not looking. With a resigned sigh you order breakfast, spend the next hour idly munching upon it, waiting for your sister to finally get her lazy ass out of bed. Eventually she stirs, and yawning a good morning she stumbles into the bathroom, not bothering to close the door as usual so you are forced to listen as she voids her bladder. Lisa plops down into the chair across from you with a smile, wearing little more than an overly large shirt and her underwear, an outfit which makes perfect sense considering the heated locale. Cheerfully devouring some fruit, she kindly asks if you had any ideas what you wanted to do today? After all, yesterday you two had such a great time at the aquarium, Lisa hadn't seen you that excited in years! In the face of such relentless enthusiasm you give in, and tentatively raise the idea of going snorkeling together? Beaming, your sister happily agrees.

You had always felt somewhat disgusted whenever your sister had worn something showy, a natural reaction for a sibling to have, but also one born out of disapproval of her loose living. Still, you grudgingly had to admit that Lisa looked absolutely stunning in her yellow bikini, no wonder so many men were desperately enthralled by her. Her tanned skin gorges upon the sunlight, the dappled reflection of the water only serving to enhance her beauty, even with the giant goggles and snorkel goofily attached to her face she still turned heads as you strode deeper into the surf together. She even held your hand as she guided you into the ocean, something you could barely tolerate, yet over the past few days, and against your better judgement, you had felt yourself warming up to your benighted sister, but just a little bit. You get a faceful of Lisa's ass as she smoothly switches from walking to swimming, and a slight tingling fills your groin; perhaps you should not grow too relaxed around this slut lest you be corrupted... But the next few hours pass in a delightfully wholesome fashion, the pair of you leisurely swimming along the reef and admiring the reefs and flourishing wildlife; it was almost enough to make you forget what a whore Lisa was.

It was only later that day though, that the old Lisa you knew so well started to shine through this charade she was putting on. You were relaxing in a small, shaded pool, secluded by shrubbery with your sister curled up intimately close to you, chatting idly about how the day had gone when she finally pops the question. Wearing the sly grin universal to older siblings everywhere, Lisa asks, "So, tell me about this girlfriend of yours, is she cute?" Blood rushes to your face immediately as you sputter at the sudden inquiry, which only makes your sister's smile grow ever more predatory. She squishes herself against your side, throwing an arm around your shoulder and cooing, "Don't be shy, show me a picture of her, c'mon!" Flustered, you haltingly pull up a picture of you beloved on your phone for Lisa to hem and haw at appreciatively, her eyes flicking all over the screen as she judges her in a thousand minute ways before nodding in approval, "She looks pretty enough, has she been treating you well?", Lisa gives you a knowing smirk, "How is she in bed?" A surge of outrage fills you as you angrily inform your dear sister that you and your girlfriend had not engaged in any such foul activities, nor would you be until you were happily! Lisa gawps at your outburst, cold fury crossing her face before giving way to worry, "Is it... not working for you two in bed," she places a hand on your thigh in support, mere inches away from a bulging pressure in your shorts, "Are you... unable to get it up with her?" You repay her honest concern with open scorn, grumbling angrily, you surge up out of the cozy pool and storm off back to your room, leaving Lisa yelling platitudes at your retreating back. Really, she really just did not understand!

Lisa watches her baby brother stomp away with hurt roiling in her stomach, what the fuck was wrong with him? Well, she partially knew, honestly how could she not feel more than a little guilty about being an awful older sister growing up? Being the village bicycle had satisfied her powerful sexual needs, but it had no doubt given her brother all sorts of unwanted pressure and attention. Of course, once she had become an idol, her sexual appetites had grown voracious, and no doubt embarrassing to her younger sibling back home, but she had always made sure to try and send gifts to cheer him up. Instead he seemed to loathe Lisa, and no matter how hard she tried to patch things up, things always fell apart, usually whenever he caught her slaking her desires with some new lover. But not on this trip! No, on this trip Lisa had been on her best behaviour, applying every ounce of her willpower to keep her lusts in check, engaging in only the most innocently enjoyable activities with her brother; displaying nary a glimpse of her usual sex life. In spite of that, he had been downright weird since he had gotten here, well, more so than usual. She had expected the customary puritanical song and dance, but with him having a girlfriend for a couple years now, she had hoped he would have opened up a little. But no, instead if anything he seemed even more repressed than normal, getting hard constantly and always on edge about everything. He was leaking so much at night Lisa could smell his precum staining the sheets in the morning, and she was honestly surprised his raging erection had not torn a hole in his boxers whenever he scrambled out of bed to use the restroom. Hell, he hadn't masturbated even once since they had gotten to this tropical paradise, most guys would have blown a few loads in the shower and dispelled the tension, if anything Lisa was not sure if he had cum even a week before the trip!

The constant reek of pent up semen in their room was starting to get to Lisa, she was already feeling twitchy, having deprived herself of sexual stimulation for so long, this was probably the most days she had gone without fucking in years. She really should take her own advice and at least masturbate, but the last thing she wanted was her brother sheepishly returning to apologize only to find her knuckle deep inside herself, so she endured. Still, something was obviously wrong in her little brother's relationship, and she was determined to fix it; after all, even as warped as she had become, she still felt responsible for him as his older sister. But first, Lisa needed some advice, and not from the other girls in Blackpink. Jisoo would give some well-meaning yet ultimately useless suggestions, Rose would offer up some complicated scheme that would really just be a front for sadism, and Jennie would simply message 'On my way', before showing up and traumatically fucking the life out of your brother in under half an hour after landing. No, Lisa needed to ask some of her more.... normal friends; well, relatively normal. Minutes later she was chatting avidly on the phone with Jihyo and Nayeon, both of whom were appalled by the situation their dear friend was in. Jihyo was apoplectic that Lisa's brother was not putting such potent loads to good use and impregnating his girlfriend, while Nayeon was practically drooling at the thought of being the first one to receive said load. But after a solid hour of intense conversation, the trio had produced a solution that would undoubtedly solve Lisa's darling brother's problems. It would merely require Lisa to break one of society's oldest taboos, but having broken so many already, what was one more?

You feel thoroughly wretched as you lay upon the massive king bed, your sister had been only showing you concern, and yet you had brutally rebuffed her kindness. Normally it was so easy to hate Lisa, you would only need to turn a corner while fetching ice and find her being publicly spitroasted by strangers like some sort of cheap whore, but this time at least there had been none of that. She had been the sweetest older sister a brother could ask for, constantly indulging him, taking him to see all the sights and lavishing him with love and attention; it made you uneasy. Surely Lisa was hiding something, some depraved scheme that she was enjoying while being outwardly wholesome, it had happened before, more than a few times actually. But this time she had seemed genuine, which only left you all the more conflicted, were you the one in the wrong this time? Your morose musings are halted only when Lisa enters the room, who quietly joins you on the bed, patting you reassuringly on the shoulder, "Hey, I'm sorry if I upset you earlier today, why don't we have an early night okay? I'm sure things will be better in the morning." Mulishly, you nod in assent, and slowly join her for a simple dinner at the small table, which passes by in awkward silence. Lisa only speaks up as you get into bed, "Leave your shirt off, I think something is wrong with the AC, it feels really stuffy in here..." She's right, so with reticence you take it off, and snuggle in under the covers as Lisa joins you in bed. She gives your forehead a kiss, "I love you baby brother," before flicking off the light. Perhaps the morning would heal your rift?

Once again you awaken with an inconveniently large erection impaling the mattress, with a now-familiar hot spot behind you. Groggily, you attempt to wriggle out of bed to douse your morning's embarrassment once more, but find your way barred by an arm thrown around your chest. Your confusion only grows as you realize the heat from your sleeping sister was not from her laying nearby you, but rather because she was pressed up against you, with two hard points supported by surprising softness pushing into your back. Unable to process this development, you attempt to escape Lisa's clutches, but her arm holds you tight against her warm body, and your struggles only serve to wake her up. Your big sister stretches languidly against you, which only serves to emphasize what exactly her supple form feels like as it slides against your skin; you were not the only one going shirtless it seems. You feel a perverse fascination with the sensation of Lisa's breasts, and are distracted enough that when she casually pushes onto your back and slips atop you, you offer little resistance. She gives you a sleepy smile, her face mere inches away from your own, and gives you a kiss, "Good morning baby brother, it's time to make things better..." Displeasure wells up within you once more, and you tartly ask for her to get off you, and to put some clothes on. Lisa laughs gently at this and sits up, allowing the sheets to cascade down her smooth body, revealing her perky tits, the lighter skin making the dark of her erect nipples stand out all the more; and further down... Further down the bare skin of her thick pussy lips squishes against your gargantuan hardon, the warmth of her sex burning against your shaft. You stare up in shock at your older sister's nude body, as she patiently allows you to drink in the sight of her, before sliding her hands up your chest, "Are you ready for it? Just relax, and let your big sister do all the work."

Belated realization finally hits your brain hard enough to dispel the fog of arousal filling it, and you snarl in denial at Lisa, get the fuck off of you! But your sibling ignores your demands, and when you try to push her away she catches your hands and pins you down with surprising strength; as she frowns in annoyance, "Fuck, calm down! I am sick and tired of your weird chastity bullshit, it's not normal, so I'm going to take some responsibility as your older sister and fix things," Moving your hands above your head so she can keep them down with one of hers, she smoothly reaches down and pulls out your filthy dick, which drools disgustingly in excitement. Running a finger through the bubbling precum, Lisa seductively licks it clean, before giving you a sharp look, "Wait, when was the last time you came? Just how pent up are you?" Flushing with impotent fury and embarrassment, you answer truthfully, it had been two weeks since your treacherous manhood had last filled your sheets while you slept. Your sister shakes her head incredulously, "Yeah, that is fucking weird, you have a cute girlfriend, use her you moron; or just masturbate like a normal guy!" Lisa sighs, "Okay, let's do this, time to get your cherry popped little brother!" Regaining her usual cheer, your sibling ignores your struggles as you writhe and buck beneath her, her panties shoved into your mouth to stifle your continuous screams of outrage, as she slowly lines herself up. Your older sister gives you the sweetest smile, "I love you," before taking your virginity.

The sordid heat of Lisa's cunt engulfs your sensitive member, its soft folds slobbering all over your shaft as it devours every inch of you until her lower lips kiss your crotch. You groan in despair as your innocence is lost, you had intended that your first time be with your beloved on the night of your marriage, but instead your slut of a- Your body abruptly silences your internal raging as it floods your brain with pleasure, responding to the overwhelming and novel stimulation coming from your cock, it reacts naturally. You groan as your hips slam treacherously upwards, and the fattest load of your life explodes into your sister, richly rewarding her pussy for taking your virginity. Lisa lets out a soft gasp as you creampie her, she had barely even sat on your dick and you were already cumming in her; she smirks, virgins always finished so quickly. She opens her mouth to congratulate you, then pauses and glances down, where your balls continue to pulse; slowly, she slides herself back up your shaft as you gradually fill her pussy with your seed. Post-coital bliss wrestles with horrid guilt, as the catastrophic euphoria of your orgasm fades, remorse stabbing at you for so enjoying being forcibly assaulted by your own sister. Lisa meanwhile is ogling as she tentatively pokes at her sloppy holes, even filled to the brim she was barely leaking, "Fuck, just how much did you cum in me? If this was your girlfriend, she would be knocked up for sure; shit, this might be enough to be risky even for me!" She reaches down to pat your cheek affectionately, "But see, that wasn't so hard was it, didn't it feel so nice just letting it all out? So now that you're nice and drained we..." your older sister trails off as she glances down at your still rock-hard erection, "Oh."

Lisa lets out an astonished giggle as she teases you, "Wow, just how badly do you want to fuck your sister?" Then she stops, and gives you a quizzical look, "Wait, is that it? Is that why you've been so moody around me all this time?" You growl angrily up at her, and she winces as she remembers your gag, once removed however, you fervently deny her claims, while a creeping horror fills you as a little voice in your head agrees with her. But no matter what lies your mouth might say, your cock was entirely truthful as it lets out another leak of precum, beyond eager to be inside of your sister once more. An awkward silence falls as you both stare at your engorged manhood, before looking at one another for a time. Lisa's face crumples as she sobbingly embraces you, holding you tight as ugly tears course down her face, "Oh, you silly idiot, you should have told me! You've spent all these years watching everyone else have their turn with your big sister, but never you! Fuck, I should have known you would be jealous! I'm so sorry for being such a failure of a big sister!" Tentatively, you delicately bring you arms around Lisa, torn between shoving her off of you, or accepting that she may very well be right. Were you so violently against any hint of sexuality because you felt that your sister had spurned your unnoticeable advances while growing up; was that why you loathed her, out of fury at being denied? Your doubts shrink as Lisa kisses you once more, the wetness from her tears anointing your cheeks as her tongue pushes deep into your mouth, sloppily making out with you before pulling back. She gives you a loving smile, "Don't worry, your big sister will take responsibility for this, I'll fix things I promise!"

Beaming, your older sister sits on your cock once more, but this time Lisa was intent on not stopping until you were fully satisfied. You both moan as your member pushes through the goopy remains of your last load, and you share a knowing look; this well and truly was incest now, and it felt so right. Your sibling holds your hands as she rides you, eschewing her more showy techniques for a more primal slamming; your wildly bucking hips would have ruined any complex movements. Semen sprays everywhere as your ferocious sex expels it from Lisa's pussy, making an absolute mess as it drizzles over your skin. Your sister groans, "Fuck, no wonder you were pumping the sheets full of precum every morning, it must have been torture for you to be so close to me yet unable to relieve yourself," she gives you a wicked grin, "But now you can pump your sister full every morning instead!" The perverse thought of fucking your own sister for the rest of your trip fills you with excitement, and you swiftly grasp her petite waist to hold her steady as you pound away at her sopping cunt. Lisa's eyes roll back as she lets you have your way with her, her pussy spasming in anticipation of your next load, her hands hurriedly putting her hair into a messy bun to get it out of her face. Grunting, you creampie your older sister once more, slathering her folds with thick semen as she climaxes from the sordid pleasure of getting pumped full of cum by her baby brother. Shuddering, the pair of you makeout as your cock softens, but it is quick to surge back into full rigidity as Lisa idly rocks back and forth atop you, "Again?" she asks with a perceptive smirk.

You pump between Lisa's supple thighs with virginal passion as your sister simply lays back and takes it. Her legs wrap tightly around your waist as her hands roam your back and chest, spurring you on as you slam deep inside of her, "Oh fuck yes baby," Lisa gasps "It's your turn now, you've watched everyone else take their turn with your big sister, but she's all yours now!" You kiss her fiercely in response, as you unceasingly plow a furrow in your own sibling, your balls drenched with your congealed sexual fluids. Lisa shudders as she climaxes once more, her folds greedily massaging your shaft as you continue to fuck through her orgasm. You bite and suckle upon her neck as she holds you close, urging you on, "God, don't stop little brother, just keep fucking me until your drained! I don't care how nasty you want it, your big sister will do anything to satisfy you, I promise!" You take her up on that, as you feel your next load churning through your balls you abruptly pull out of the warm confines of your sister's pussy, before hurriedly scooting forward to shove your leaking cock into her face. Lisa knows exactly what to do, and opens her mouth in invitation as locks eyes with you, nodding encouragingly as you furiously stroke the cum out of your cock. Groaning, you jizz on your sister's face, the same face that was plastered on billboards and advertisements around the world, was now getting painted with fat ropes of your semen. Lisa doesn't blink, even when your salty load splashes against her eye, lovingly staring up at you as you cover her million-dollar face with your seed.

Lisa stops you from retreating, and with affectionate care cleans your cock off with her mouth, diligently sucking the dregs of your load out of you; before simply sucking on you for the fun of it. You quiver as your older sister gives you your first blowjob, her tongue skillfully caressing the underside of your member, as her naughty lips wrap tightly around your shaft. The sensation left you giddy, and Lisa's eye's narrow with satisfaction as she notes your obvious pleasure as she slurps up and down your length. But like any boy, you wanted to go deeper, and your sister was more than happy to oblige you. You moan loudly as Lisa deepthroats you, holding onto her bobbing head for support as you struggle to stay upright; gasping her name as she skillfully works your next load out of you. The pressure becomes unbearable, and you nearly collapse as you fill your older sister's mouth with your cum, streamers of semen even spewing directly into her stomach as she takes your spasming cock to the hilt; her salacious tongue hard at work coaxing your balls. Lisa doesn't even bother to wipe off the jizz drying on her face after you finish clogging her mouth with sperm, she can tell how much it arouses you.

You would have thought you would be satisfied by all that, but your bulging erection said otherwise. Giggling, Lisa merrily allows you to bend her over, hoisting her ass into the air and arching and spreading her cheeks to reveal your sloppy seconds leaking out of her gaping lower lips. Perverse pride permeates through you at the sight of your sister's cunt crammed full of your seed, how often had you seen someone else's load drooling out of your sister? But now she was yours, you had placed your own claim on her pussy, and you were eager to continue doing so. You shiver with barely controlled excitement as you grab her surprisingly curvy hips, you realized now how much your sister's perky ass aroused you, your cock head already glistens with precum when you push into the sloppy mess inside of Lisa. Who smirks as she feels you enter her, she can feel how eager you were to fuck her from behind just from how you penetrated her, and she knows exactly what her little brother wants, "Mhmm that's it, I bet you've been waiting to fuck me doggy this whole time, every guy does," her smile grows smug as she feels your dick stiffen, "I just love showing it off, I'm sure all your friends were blasting fat loads to my ass all the time..." she abruptly twists backwards and lovingly touches your cheek, "But now it's your turn to give your sister a good pounding, so don't hold back, okay? Lisa blows you a kiss, and moments later you are fervently fucking your older sister as if your life depended on it, who obligingly curls back down into her sharp arch to better pleasure her little brother's cock. You plow Lisa's perky butt, her cheeks slapping loudly against your skin as you work out yet another urge that had festered in your heart for years; this time, Lisa's ass was yours. Lust burns through you as you jackhammer your slut of a sister, the sheer eroticism of finally fulfilling your darkest fantasies driving you to orgasm faster than you anticipated. Howling your sister's name, your balls exert themselves once more and douse your sibling's cunt with sperm, who squeals in delight as she revels in the sensation of being filled, "Fuck yes! Fill your big sister up, cum in me, breed me!"

It was that last phrase that had you thrusting away again even before you had finished recovering from your climax, gritting your teeth as you force your tiring cock to rise to the occasion once more. Lisa looks back at you in bemusement, curious as to your sudden second wind, until she realizes, "Oh... does breeding me excite you that much," she giggles in delight, "You dirty pervert, it isn't enough to just fuck your older sister, you want to impregnate me as well?" Your increased pace is all the answer she needs, and Lisa ponders it for a moment before giving you an enormous and degenerate smile, "Why not? If you manage to knock me up, I'll keep it, it's the least your big sister can do... wait did you just cum in me again? Lisa laughs as she feels your cock spasming inside of her, "Fuck, you really want to put a baby in my belly don't you? At this rate even an idol like me might get fertilized!" Perversely, you feel yourself getting hard once more, your older sister was right, the thought of knocking her up aroused you immeasurably; but she stops you before you can continue fucking her, "Hey! Let it settle in me, how is the sperm supposed to reach me if you keep fucking it out of me? Why don't we switch holes for a little bit," Lisa smirks as she feels your manhood become nearly as stiff as it had been at the start, "Yes baby brother, you can use my asshole as much as you like!" You groan as urgently mount your older sister's tight asshole, you fucking love your sister, Lalisa!

Lisa purrs contently as she strokes her younger brother's hair as he sleeps soundly upon her tender breasts, his semen drying inside both of her holes. The familiar ache of her over-used body soothes her, she hadn't expected her sibling to have as voracious a sexual appetite as her, but she had certainly enjoyed it. But as his big sister, she still had some work to do while her dear boy peacefully slumbered, so humming quietly to herself, she gets to work. First she informs her friends of her success, Jihyo is already enthusiastically hoping her egg gets fertilized, while Nayeon is frothing at the mouth with jealousy for such a spectacular deflowering. Next she uses her brother's phone to send his girlfriend some select clips from the recording she had made of their coupling (Her brother could be so oblivious sometimes, how did he not notice her phone pointing at them the entire time!), cheerfully informing her what happened as well as telling her that she expected at least five nieces and nephews to spoil rotten. An hour later, his phone pings, and she enjoys a minute-long video of the "pure and innocent" girl squirting wildly to the sight of her boyfriend fucking his sister; no doubt she would be getting pumped full of cum within an hour of the couple reuniting. Finally, Lisa muses upon the enormity of what she had just done, she had forced herself upon her own brother, and engaged in depravedly incestous sex with him, oh and there was a very slight chance she might be carrying his baby as well. She was sopping wet at the thought of doing it again and again for the next week.

Lisa was looking forward to not leaving their room for the rest of the trip...
