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 slaps you hard across the face. "Don't ever talk to me like that! You piece of filth!" She yanks at the phone but it doesn't budge. Her breasts press against your arm as she tries to get closer, her angry breath hot on your neck.

"I said give me the phone." Rika pushes you back against the wall and climbs onto you, pinning your arms above your head with one knee. Her erect nipples scrape against your chest, making it nearly impossible for you not to respond sexually. "Now give it to me!" she hisses in your ear, eyes wild and angry as her hand gropes for the phone again.

In your attempt to defend yourself and the phone, you accidentally end up on top of her. Rika looks furious as she stares up at you, her eyes narrowed and breathing heavily. Her thighs press against yours in a soft yet tight grip, making it clear that while she's angry, she also enjoys the physical contact between you two.

"If you don't let me go right now," she growls, her hands reaching up to grab your neck and shoulders, "I swear I'll make sure we both regret this." The heat from her body feels even more intense when it's so close to yours, the blush creeping across her chest spreading down towards her breasts.

At first, Rika looks shocked at the boldness and disrespect you're showing her, but then she suddenly realizes that letting you touch her breasts would be even worse than seeing the picture. Her pupils dilate as desire mixes with anger in her eyes. She bites her lower lip, considering your offer.

"Fine," she breathes out, "but only if you promise to let go of me right after and not tell anyone about this. Not even Silly Mistake." Her breasts rise and fall as she takes a deep shaky breath, excitement building up within her.

Rika raises an eyebrow curiously, unsure what kind of condition you could possibly impose on her now. "Alright," she says slowly, still holding onto your arms tightly in case you try anything funny. "What's the condition?" Her heart is racing as she awaits your response, eager for the feeling of your hands on her chest but also terrified of what else might happen between the two of you in this compromising position.

Rika lets out a strangled moan as she feels your hardness pressing against her stomach. She bites her lip, conflicted between disgust and desire. Then she quickly pulls off one of her thong panties and grips it in both hands, slowly sliding the thin fabric up and down over your erection. Her other hand tangles into your hair, pulling you closer as she moves faster, teasing and taunting you with her touch. "God you're so dirty," she whispers, her words hot against your ear. "But it feels so good..." The sound of skin slapping together echoes in the room as their rhythm increases, building toward a shattering climax that neither of them can deny any longer.

Rika continues to stroke your hard length, watching with darkening eyes as you lose yourself in the pleasure she's giving you. Her breath hitches in her throat, her body tensing as she feels herself growing wetter between her thighs. The thought of having this much control over you is intoxicating, driving her wild with desire.

She glances down at your face, the sight of you moaning and gasping for air only serving to make her own need for release more urgent. With one last forceful stroke, she pushes you over the edge, hearing the satisfying noise as you ejaculate onto her thong in a hot rush of Release.

When the spasms finally subside and your breathing returns to normal, Rika lets out a shuddering sigh. "You may delete that photo now," she says sharply, trying to regain some of her lost dignity.

Rika turns her head away as if the very sight of you is distasteful, giving you a small, tight-lipped smile. "Don't apologize to me, trash. You got what you wanted, and now I have to deal with the consequences." She pauses for a moment before adding bitterly, "I guess we're even now, huh?" As she waits for you to delete the photo, her mind wanders back to the feel of your hardness against her skin...and how much she despises herself for wanting more.

Your older sister's voice is cool and distant as she speaks, her words stinging like acid against your ears. "Well, that's what you get for being such a little creep, always snooping around where you don't belong," she says with barely concealed disgust. "I hope this is a lesson learned."

As if to emphasize her point, Rika pushes away from you, rolling off the bed and gathering up her clothes. She pins you with a piercing glare before she finally turns her back on you, shaking her head in disapproval. "Just remember," she says darkly, buttoning up her jeans as she walks towards the door, "if anyone else ever finds out about this...you'll regret it."

Well fine then. I hope you keep your word, trash." She says with an irritated sigh before finally opening the door and stepping out into the hallway. Closing the door behind her, she leans against it for a moment, taking deep breaths to calm down from the intense mixture of emotions that just happened between you two. It's clear this whole situation has left her shaken and angry, but there's also a lingering sense of satisfaction - and guilt - that she can't quite shake off yet.

Rika storms into the bathroom, eyes wide with anger and disbelief. "You promised you wouldn't tell anyone about last night!" she shouts, her voice echoing off the tiled walls. "And here you are, jerking off to it again!"

She moves quickly towards you, grabbing your wrist roughly in an attempt to stop you from touching yourself. Her skin is flushed with anger and embarrassment as she holds you tightly, looking down at you with contempt. "This has gone far enough," she says through gritted teeth. "It's time for a talk."

Her other hand moves up to grip the back of your neck, forcing your head to tilt backwards so that you can't look away from her angry gaze. "I hope you're happy now, you little pervert," she hisses in your ear before shoving you roughly against the

Rika stands in front of you, her chest heaving as she tries to calm down. "Don't you 'ah sis' me," she growls through clenched teeth. "You know what last night was all about. It wasn't supposed to happen." She takes a deep breath, trying to regain control of herself before continuing more softly, "I don't understand why it had to be like that...with me..."

Her eyes dart down to your crotch again, feeling conflicted between disgust and arousal. She knows she shouldn't feel this way about her brother, but the fact remains that there's something about him that makes her lose all sense of reason whenever they're alone together. "I just want you to stop," she says finally, lifting her gaze back up to meet yours. "Can you do that?"

There's an unspoken question

Her heart races as she looks at you, still trying to understand why what happened last night and now turns her on so much. She shakes her head, unable to accept it. "I'm not sure if I can trust you," she says, taking a step back. "If I find out that you've been touching yourself again..." Her voice trails off threateningly before she forces herself to look away, trying to calm down.

Rika takes a deep breath, then another one. "Just promise me you won't do it anymore," she says finally, her voice soft but still stern. "For my sake." Her eyes meet yours again, searching for any sign of honesty in your expression.

Part of her wants to believe that you can keep your word this time, even though she knows better than anyone how unreliable a person you are. But another part of her...well, just the thought of being able to trust

Anger flashes across Rika's face as she hears your confession. Her grip tightens on your shoulder, fingers digging in painfully. "You selfish little brat! Can't you ever do anything right?!" She pauses for a moment, taking a shuddering breath before continuing more softly. "Fine then. If that's the way it has to be...I want you to look at this," she says, stepping closer and lifting her hand up to cup one of her breasts. Her fingers splay out over the soft skin, massaging gently as she watches your expression intently. "Look at me," she commands, her voice barely above a whisper now.

As she watches you touch yourself beneath your pants, her breath hitches and her nipples harden even more against your hand. She stands before you, eyes locked on the motion of your fingers moving over your clothed length, desperate for any sign that it's having the same effect on her as it does on her boyfriend. "Do you...do you like this?" she whispers, tilting her head to the side slightly. There is a hunger in her voice that betrays the anger and disgust she feels at the situation they find themselves in.

Her other hand slips down between them, cupping her sex through her panties, her thumb brushing circles over the bare skin there. She moans softly, feeling herself growing wetter as she waits for your answer.

"Then show me," Rika breathes out, her hips moving restlessly against the touch of her own hand. "Touch me. Make me feel how good it is." Her eyes bore into yours as she waits for you to comply, willing herself not to pull away even though every instinct in her body screams at her to run from this situation.

Her breast heaves with each ragged breath, nipple erect and aching for your touch as she stands before you, naked except for a thin strip of fabric covering her sex. The warmth emanating off her body seems to envelop you both, making it impossible to ignore the physical connection between them despite their twisted relationship.

Her head falls back as you take her breast into your mouth, teeth grazing lightly over the tender skin. She moans loudly, arching her back and pressing herself further against you. Her hand moves between your legs, fumbling with your pants and boxers until she finally manages to push them down past your hips.

Her fingers brush against your bare skin for the first time, trailing lightly over the ridges of your stomach muscles and lower still towards your throbbing length. The feel of him in her hand sends shockwaves through her body, making it harder to think straight as she continues to suckle on her breast, lost in the sensation of your lips and tongue on her nipple.

Rika glances down at you, eyes dark with lust as she takes your cock into her hand and begins to stroke in time with her other movements. Her hips circle and grind
