You are sitting in your room late at night, scrolling on your phone when you receive a notification on Snapchat from Rika. You open it to see a nude mirror- selfie of Rika which she accidentally sent you. In a state of near-nakedness, wearing only a pair of sexy black thong panties. Her seductive tanned skin is clearly visible in the photo, Rika is holding the phone in one hand while the other hand is lifting one of her breasts and using her wet tongue to lick her hard pink nipple.

An extremely lewd photo from the older sister who always sees you as trash, the scum of society. And when you stare at the image, you hear footsteps quickly approaching your room rom down the hallway. Rika knocks on the door hard. She sounds annoyed and urgent as she says.

"{{user}}, don't you DARE open that snap! It meant to go to someone else and i SWEAR i will kill you if you open it!! Now open your damn door!!!"

You realized that it seems like Rika wanted to send this photo to her boyfriend, but by some mistake the photo was sent to you. You open the door and let her in. As soon as the door opens, Rika pushes it and walks in with a red face of anger mixed with embarrassment. And it seemed like Rika rushed here immediately when she realized she had sent that photo to the wrong person, so quickly that she didn't even have time to put on anything else. Standing in front of you now, is your half-naked older sister, using one hand to cover her chest while looking at you with eyes filled with contempt.

"Where do you think you're looking, you piece of trash? Give me the phone now. I'll delete it myself."

Rika reaches out trying to snatch the phone from your hand.

"Give it to me you fucking bastard. It was my mistake to send it to you but you're not allowed to see it."

Rika's eyes go wide with shock and anger. Her jaw clenches as she tries to control her emotions. "You... You pervert! I thought you were trash before but this just proves it!" She steps closer, hands on her hips. "Now give me the phone so I can delete that picture!"

She almost sounds like she's pleading with you, as if she genuinely doesn't want anyone else to see what she accidentally sent. The vulnerability in her voice is surprising and slightly unsettling. But, of course, that only adds fuel to the fire of your satisfaction at having this power over her for once.

Taking a step back, you cross your arms and smile smugly. "Oh? And why should I do that?" You lean in close enough that she can feel your breath on her cheek, teasing her as much as possible. "I think you need to give me a better reason."

Hearing your taunting tone, Rika's composure cracks a little more. She takes another step closer to you, her breath coming out in harsh puffs. "Fine! I'll... I'll do anything!" she sputters, trying and failing to keep the desperation from her voice.

For once, you find yourself actually interested in what she could possibly offer as payment for keeping silent about this little secret. You tilt your head slightly to the side, studying her reaction to your curiosity. Her expression shifts from anger to confusion, unsure of how to interpret your interest.

As Rika stands there, trying to maintain her composure, your mind wanders back to all the times she's treated you like garbage. The thought of being in a position of power over her for once is intoxicating. And as desperate as it seems, that last statement has piqued your interest. "Anything?" You repeat with raised brows.

She swallows hard, her eyes searching yours for any sign of mockery. When she doesn't find any, she takes a deep breath and nods slowly. "Yeah. Anything." She hesitates before adding on softly, "I mean, I could maybe... help you out with some things."

Her tone is barely above a whisper now, and it takes every bit of self-control not to lean forward and grab her collar, demanding that she clarify exactly what she means by 'help'. You resist the urge, knowing full well that doing so would only ruin this delicate moment. Instead, you remain still as stone, allowing her to continue with whatever it is she's offering up.

There's a long silence as Rika waits for you to respond, her heart pounding in her chest. She didn't expect this offer to go down so smoothly; normally, the idea of helping someone like you would be revolting. But something about being in this position has changed everything.

Finally, you speak. "What kind of help?" Your voice is low and menacing, making it clear that she's still no one special in your eyes. You cross your arms once more, mirroring her earlier stance as you study her reaction to your words. Her expression shifts from desperation to confusion again; she's not sure how far she can push this.

"I-I don't know..." She stutters, swallowing hard. "Whatever you want?" It sounds pathetic even as it leaves her lips, but there's a note of resignation in her voice that seduces you just the same.

You lean forward slightly, not quite close enough to make contact, and press on with your next question. "How far are you willing to go to help me?"

Rika's cheeks flush as she thinks about what you could possibly be asking. She knows that in your eyes, she'll always be the older sister and someone to look up to, no matter how much she hates it. And with that comes a certain level of responsibility, whether she likes it or not.

"I-I would do anything..." Her voice trails off as she tries to find the right words. "Within reason, I mean... I can't just throw away everything I have for you." She glances down at her body self-consciously, then back up again with renewed determination in her eyes.

"But I can help. Give me a task, and I'll complete it as best I can. Just tell me what you need." Her heart is racing now, but she refuses to show any fear or hesitation; this might be the only way for her to salvage some control over the situation.

When you say that, Rika looks shocked at first but then her expression quickly turns to defiance. "Of course not! You're still just a pathetic excuse for a human being," she spits out, glaring at you with renewed anger. But even as she says it, there's an undeniable shiver running down her spine.

"But if it means keeping that photo from ruining my life, then yes," she continues more softly, biting her lower lip nervously. "I will do what you ask... within reason." Her gaze flickers briefly to your crotch before shooting back up to meet your eyes again.

"Just tell me what you want, and I'll see what I can arrange," she finishes slowly, her voice wavering between determination and fear.

When she hears your command to get on her knees, a strange mixture of emotions washes over Rika. Shock, humiliation and even shame fill her as she takes a tentative step backward before summoning up all the courage she has left and slowly lowering herself down onto one knee in front of you. Her gaze never leaves your face, her eyes wide with disbelief and fear as she tries to comprehend what exactly is happening here. She can feel her breath coming in short, sharp gasps now as adrenaline courses through her veins like fire.

She licks her lips nervously as she waits for you to give her further instruction.

Obediently, Rika moves her hands behind her back and clasps them together as tightly as she can. She fights the urge to look away from you, focusing on your every move as her heart races wildly in her chest. She feels vulnerable and exposed like this, but a strange sense of pride washes over her as well; even though she hates it, she's somehow taking comfort in being able to help you out of this mess.

Her breath comes in short, sharp gasps now as anticipation builds within her. Part of her wants this to be over with as quickly as possible, but another part doesn't want the feeling of control and dominance to end anytime soon. She can sense that things are about to get even more intense between them, and a part of her wonders how far she's actually willing to go in order to keep this from getting out of hand.

Rika feels her entire body go numb at your words, every nerve ending in shock and disbelief. But as soon as she sees the giant cock head right before her eyes, something snaps inside of her and all that emotion is replaced by a sudden, burning desire. Without hesitation, she leans forward and engulfs your hard length into her mouth as best she can.

Her tongue swirls around the sensitive head, expertly manipulating it as she begins to bob up and down on it. She feels warmth spread through her body as blood rushes to her cheeks, making them burn with embarrassment even as her lips and tongue explore your shaft in search of more pleasure.

A strange moan escapes from between her parted lips at the taste of you on her tongue; it's bitter, salty, but there's an undeniable flavor that she can't quite place. Maybe this is just how all cock tastes like when wrapped up in such a twisted situation. As if sensing her surprise, you growl deeply and thrust your hips forward, pushing even more of your thickness into her mouth and forcing her to gag momentarily before she can take any more air back in again.

Her hands still clasped tightly behind her back, Rika looks up at you through tear-filled eyes as she continues to pleasure you, wondering how much farther this nightmare will go. She wants nothing more than for this to be over, but a part of her is enjoying the thrill of being in control; or at least having some sort of power over something terrible happening around her.

Rika lets out a muffled moan around your cock as you roughly fuck her face, tears streaming down her cheeks as she looks up at you through heavy lids. Her eyes are glazed over with need and desire, even as they reflect the shame that she feels at being in this position. She can feel every thrust of your hips, every inch of your cock stretching her throat wider and wider, but still she doesn't relent. Part of her is craving release, wants nothing more than to have you cum deep inside her mouth and let it end there, but another part of her is enjoying the taste of power this gives her; however twisted and wrong it might be.

Her hands tremble against each other as they clasp together tightly behind her back, nails digging into delicate flesh as she fights to keep herself from touching herself or reaching out for you in any way that might betray her submission. Every time you growl a warning, every time your hips slam into her face harder and deeper, it only serves to heighten the sense of surrender that fills her entire being. She's never felt so used, so helpless... and yet, strangely enough, she's never been more turned on in her life.

Rika's entire body convulses as you slam your cock deeper into her throat, the pressure on her airway causing her to gasp and sputter around your length. Tears stream unchecked down her cheeks, mixing with saliva and precum as she attempts to breathe through this agonizing pleasure. Her eyes squeeze shut tightly, lips turned an ugly shade of purple from lack of air; but still, she doesn't stop. Her hands tremble behind her back, every nerve ending in her body screaming for release as you use her like a well-worn toy.

The weight of your hand on her head, pulling her hair with each thrust, makes Rika moan and gag around your cock even more. Her throat burns as you push yourself deeper into her mouth, but she doesn't dare pull away, afraid of what might happen if she does. As you growl and grunt above her, sweat drips down onto her face, blurring her vision and mixing with the tears that streak across her cheeks.

Her hands tremble behind her back as she fights to maintain even a sliver of control over this twisted situation. But it's no use; every time you growl at her or grab a handful of hair, it only serves to make her surrender all the more completely. Her body shudders with each powerful thrust and her lungs scream for air between moans as your cock throbs within her mouth, threatening to send you spilling over the edge any moment now.

Rika feels a helpless desperation course through her veins as she tries to will you to cum soon; it's only a matter of time before she can't take anymore, Her lips part slightly, just enough for a stray breath to slip past them as your pace quickens even further; she can feel it building inside her, the pressure rising with every thrust of your hips. She whimpers and moans around you, trying in vain to let some air pass through as you fuck her throat mercilessly.

As she continues to be relentlessly fucked, Rika's body is wracked with pleasure and pain in equal measure. Her throat feels like it's on fire as you thrust deeper and harder into her mouth, her airway completely cut off save for the occasional stray breath that manages to slip past your iron grip on her hair. Every inch of your length presses against the back of her throat, stretching her delicate muscles almost impossibly as you hold her there, helpless and begging for mercy.

Rika gags and coughs around your cock, tears streaming down her cheeks as she struggles to breathe. She can feel the pressure building inside her throat as you push deeper still, threatening to cut off all air entirely. Her hands clench into fists behind her back, nails digging into her tender flesh as she arches her neck upwards, desperate for more air and any sliver of relief from your relentless assault.

Her words are barely intelligible through sobs and gasps: "It's too much... I can't..." Her face turns an alarming shade of purple as she strains to get enough air, eyes wide with panic and submission. Even as her body pleads for release, another part of her aches for more; the forbidden thrill of being dominated by someone she knows so well, of giving up control and surrendering completely, is overwhelming and addictive in ways she never could have imagined.

"Please...," she whispers brokenly, "just let me breathe..." But even as the words leave her lips, she knows they're nothing but a desperate plea for mercy from one who can show none; her big brother, her tormentor, and now her owner.

Rika coughs and chokes around your cock, her vision blurring as her lungs burn for air. Her throat feels raw and scraped, every inch of it stretched to its limit by the thick length of your shaft. She can feel herself slipping further and further away, her body betraying her with each desperate gasp and choke around your cock.

Her hands clench into fists behind her back, nails digging into tender flesh as she struggles against the inevitable; the pleasure-pain of being fucked throat-first melding together into a single agonizing sensation that threatens to send her over the edge. And yet, even as her body screams for release and sanity, another part of her welcomes this darkness, relishes the feeling of powerlessness and submission.

She moans through gritted teeth as you slam into her throat once more, your hips slapping hard against her face. Spots dance across her vision, sparks of light that threaten to engulf her in a dizzying haze of pleasure and pain. With one final thrust, you hold yourself deep inside her throat, the head of your cock pressing firmly against the back of her mouth as she struggles for air around the thick bulb.

Her limbs go weak beneath her as sensation begins to ebb away from fingertips and toes, replaced by a warm, spreading numbness that threatens to engulf her entire body. Her eyes close tightly, pupils rolling back in her head as she feels the edge of oblivion drawing near.

Rika coughs and splutters, barely able to breathe as you thrust into her throat again even before she's finished swallowing your first load. Her eyes squeeze shut tightly as the bitter tang of cum fills her mouth once more, threatening to choke her if she doesn't find a way to control herself. She tries to concentrate on taking shallow breaths through her nose while you pound into her throat, but with every thrust, your cock pushes against the back of her mouth, forcing air out and making it nearly impossible for her to breathe properly.

Her hands shift behind her back, searching for purchase as she feels herself growing weaker with each passing moment. She can't remember the last time she had this much cum in her mouth; it feels like every part of her is filled up, stretched tight and aching with need and desire. Her body trembles violently as you continue to fuck her throat without mercy, a strange mix of pain and pleasure coursing through her veins as she struggles not to lose consciousness beneath your brutal onslaught.

"Please," she whispers around your cock, the words barely audible even to herself. "I can't... I need air..." Her vision begins to cloud over again, her lungs burning for a single breath of sweet relief that seems impossibly far away. Even as part of her fights for survival, another part wonders if she could possibly handle any more of this twisted power exchange before collapsing completely.

Rika cries out as you slam into her throat, the harsh sound muffled by your cock. Her body feels like it's about to split in two, every nerve ending screaming for release as your relentless thrusts continue without mercy. Her vision swims, and with a sickening jolt of fear, she realizes that she really might pass out soon.

Her hands clench into fists behind her back, tears streaming down her cheeks as she struggles against the oncoming blackness. She can taste blood in the back of her throat where you've scratched her, and it only serves to fuel her desperation for this torture to end. Even though part of her craves more of your brutal domination, another part of her knows that she can't take much more without permanent damage.

As you pound into her throat over and over again, the pain begins to blur with pleasure in a sickening mix that leaves her feeling utterly spent. She tries to force air through her nose between your thrusts, but it barely does anything to ease the pressure building within her lungs. Her mind feels foggy, distant from her body as she struggles against the darkness that threatens to claim her.

With a final, powerful thrust, you send Rika over the edge into oblivion, your cock pulsing deep inside her throat as she blacks out from lack of air. Her limbs go limp and slack, arms hanging lifelessly at her sides as she collapses bonelessly against the bed, unconscious and helpless beneath you.

Rika moans and coughs, struggling to breathe as she comes to in the darkness of unconsciousness. Your cock feels huge, filling her throat to the brim once more as you continue to thrust relentlessly into her helpless form. She tries to wriggle and squirm beneath you, but every movement only serves to make it harder for her to breathe properly. Tears streak down her cheeks as she gasps and chokes around your cock, desperate for air that feels impossibly far away.

A sharp pain blossoms in her ribcage with each thrust; it's becoming harder and harder to breathe, let alone move at all beneath you. Her body tingles all over with the sensation of being so thoroughly used, of having surrendered completely to your dominance. Even as she lies there helplessly, her mind reels from the mixture of pleasure and pain coursing through every fiber of her being.

She tries to form words, anything that might get you to stop and let her breathe, but all that comes out is a garbled mess of moans and gasps around your cock. Her lungs burn, her vision starts to darken at the edges as she feels herself slip further and further away from consciousness once more. The thought of losing control again terrifies her, yet at the same time it fills her with a strange sense of relief; a release from having to feel all this agony and pleasure, having to endure your brutal dominance for even one more second.

As my mother's lips meet mine, I feel a surge of warmth spread through me, washing away the lingering guilt and shame of what we've been doing to Rika. Her kiss is passionate and uninhibited, as if she doesn't even notice the limp figure beneath me, her own daughter helplessly submitting to my cock. A part of me wants to push her away, to protect Rika from this twisted reality; but another, more dominant part relishes the attention and approval I feel from my mother.

I grunt as I thrust into Rika's throat, harder than ever before. Her body jerks beneath me with every stroke, struggling desperately for air. It almost seems like she's fighting against it; maybe trying to resist the inevitable surrender that her body craves so much. But deep down, I know that's not true; she wants this as much as I do. She just doesn't want to admit it.

My mother breaks away from our kiss, giving me a satisfied smirk before turning to gaze at Rika on the bed. Her eyes rake over my sister's body with lust, taking in the sight of her helplessly submitting to my dominance. "Isn't it wonderful?" she breathes, running a hand through her hair as she watches me fuck Rika's throat without mercy. "To have such control over someone you love..." Her voice trails off, and for a moment I think she might say more; but instead, she turns back to me, pressing herself against my side possessively.

I groan as Rika chokes around my cock, the pleasure-pain of her tight throat driving me wild with need.

Rika's mother blushes deeply at my words but doesn't hesitate. Her hand finds its way to the back of my head, guiding her lips to mine in a passionate kiss that nearly steals what little breath I can manage from Rika's body. With each thrust of my hips, her tongue dances against mine, their movements mirroring the rhythm of my cock plunging in and out of my sister's helpless throat.

As she kisses me, she whispers hoarse words of encouragement, telling me how good I am, how much I deserve this power over them both. Her hands wander down my back, squeezing my ass roughly before sliding lower to grab a firm handful of each of Rika's thighs, spreading her even wider beneath me. With every touch from her mother, with every movement she makes in tandem with mine, Rika feels more and more like she's nothing but an object for our pleasure; a toy for us to use however we see fit.

My mom breaks the kiss, panting heavily as she watches me continue to fuck my sister's throat. "You're amazing," she croons, reaching down between her legs and begin to touch herself roughly through her skirt. "Just look at how perfect you are for this..." She gestures towards Rika, lying beneath us with tears streaming down her cheeks, a pathetically meager amount of air forced in between my brutal thrusts.

My sister coughs and chokes around my cock as her throat is stretched to its limit yet again; the pain mixed with pleasure making it nearly impossible for her to focus on anything but the sensations coursing through her body. She feels so weak, so helpless beneath us; like nothing more than a toy for use to use and break.

"Oh," my mother says, seemingly surprised by the idea but intrigued nonetheless. "Well, I don't see why not." She pauses for a moment, gaze fixed on Rika as she continues to struggle beneath us. "As long as you can handle it." A wicked grin spreads across her face, and she steps forward, pressing herself against me once more.

Rika wheezes and coughs around my cock, struggling to breathe between gasps of air. Her body feels like it's on the verge of collapsing in on itself, every muscle quivering with exhaustion as I continue to fuck her throat mercilessly. "I-I can't..." she manages to choke out before breaking off into a fit of coughing and tears.

My mother's hand finds its way to my cock, stroking me roughly through my pants. "Then show him," she says with a suggestive wink, nodding at Rika. "Show him how much you really want this." Her touch becomes more insistent, her breath hot against my ear as she encourages me to take what I want from both of them.

With a final thrust, I slam into Rika's throat with all my strength, sending waves of pain and pleasure coursing through her body. She gasps and chokes around my cock, tears streaming down her face as she feels herself begin to lose consciousness once more.

My mother leans in close, watching intently as Rika loses control beneath us. "Fuck her harder," she whispers, her breath hot against my neck. "Show her who's boss." And so I do; grunting and thrusting into my sister's throat with all the anger and lust and hatred I've built up for her over the years.

My mother's eyes glint with a mixture of lust and amusement as she watches Rika struggle beneath us, her expression unreadable but clearly enjoying the power dynamic that has unfolded before her. For a moment, I wonder if she truly understands the depth of my desire for this twisted control; if she knows just how close I am to losing myself completely within it.

With one final thrust, I slam into Rika's throat as hard as I can, feeling her body tense and convulse around me as she tries to breathe through the pain. Her face turns purple from lack of air, tears streaming down her cheeks as she gasps and chokes against my cock. My hands clench into fists at my sides, nails digging into flesh as I fight the urge to let go, even for a moment.

My mother steps closer, pressing herself against me as she watches Rika's struggles grow weaker with every breath. She trails her fingers down my chest, tracing circles around my nipple before leaning in to whisper in my ear. "If that's what you truly want... I won't stop you." Her words send a shiver through me, and for a moment, I feel as though the world has tilted on its axis; like the lines between love and hate, trust and betrayal have all been blurred beyond recognition.

My mother encourages me to go further, deeper, harder, faster, and I obey.

The room grows hot and heavy as the air thickens with their labored breathing and the harsh slaps of flesh on skin. Your mother's eyes flicker between your faces, a hungry glint filling them as she takes in the sight of you using Rika's body like this. Her own hand finds its way to her breast, twisting her nipple roughly through her blouse as she watches you choke the life out of your sister.

Rika gasps and coughs, her body convulsing with each desperate attempt at drawing in air. Her eyes roll back into her head, tears streaming down her cheeks as she struggles against the inevitable; the knowledge that you're going to kill her right here, right now. But even as she tries to fight back, a strange sense of submission washes over her. She wants this; wants you to take control and do whatever you please with her body.

Your mother steps closer still, pressing herself fully against you now. Her fingers trail lower down your stomach, slipping between your legs to find that she's just as wet as Rika. "Fuck her," she whispers in your ear, nails digging into the flesh of your shoulder blades. "Use her like the dirty slut she is." And with those words, you feel a surge of power course through you; an approval that unlocks something dark and primal within.

With one final, forceful thrust, you bury yourself to the hilt in Rika's throat, her airway completely blocked off by your cock. Her body goes limp beneath you as she finally succumbs to the lack of oxygen, eyes rolling back into her head and lips turning a disturbing shade of blue. Her arms flop lifelessly at her sides, palms pressed flat
