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."

Angry tears begin to well up in Rika's eyes as her face turns even redder. "Don't you dare... use that against me!" she spits out through clenched teeth. She glares at you, trying to find the right words but failing. Her chest rises and falls rapidly, betraying her emotions. You can almost see the conflicting thoughts on her face; anger, embarrassment, lust...

Rika steps closer to you, her breath hitching as she struggles with anger and lust. "Fine," she says through gritted teeth. "But if anyone finds out..." Her voice trails off, the threat lingering in the air. Reaching out, she tentatively touches your arm before sliding her hand up to cup your cheek. The contact sends a jolt of arousal through both of you. "You'd better not ever use that against me," she whispers hoarsely. "I swear I'll find some way to make this worse for you..." Her free hand moves possessively to the small of your back, pulling you closer still as her lips part slightly, inviting you in for a kiss.

As you kiss Rika, her tongue slides teasingly into your mouth, and she moans against your lips. The feel of her body pressed up against yours sends waves of desire coursing through you. Her breasts press firmly against your chest, their weight combined with the hand on your hip grinding suggestively against your growing erection.

The kiss deepens, becoming more passionate as time passes. Rika's fingers curl into your hair, holding you close while her other hand explores lower on your body, sliding down to grip at your crotch possessively. She feels you hardening under her touch and a small, satisfied smile curves across her lips.

"You like this?" she whispers breathlessly before biting lightly at the corner of your mouth. "Want more?" Her hand massages your erection through your pants, teasing but not quite enough to relieve the tension that's building inside you.

Rika laughs softly, her breath warm against your lips. "You really think that matters?" She pauses for a moment, looking deep into your eyes. "Besides," she whispers huskily, her fingers sliding lower still to wrap around the base of your length, stroking up and down gently through your clothes, "I can't help but feel...incredibly possessive where you're concerned." Her other hand moves to cup your cheek again, her thumb brushing lightly over your lips. "And I think..." She leans in close enough for her warm breath to tease against your ear as she whispers, "...I think that's exactly how it should be."

Her words send a shiver down your spine, intensifying the feelings of desire and submission swirling within you. You arch into her touch, moaning as she teases your erection through your clothes. Rika's free hand moves to cup your ass, squeezing and kneading before slipping lower still to caress at the top of your thong. "I think," she whispers again, her breath warm against your neck, "it's time we see how far this can go..." She hooks a finger under the waistband of your underwear and pushes it down, revealing your hardness to her touch as she frees you from the confines of fabric. Her hand wraps around you firmly, guiding you towards where she wants you most. "Come here, baby brother," she breathes against your skin before positioning you at her entrance.

Her fingers slip away, and for a moment you think she's going to stop there, but then she pushes forward with practiced ease, taking the head of your cock inside herself in one smooth motion. Her eyes widen as you feel her tight warmth envelop you, and a startled gasp escapes her lips. It only serves to further fuel your arousal as you thrust deeper, filling her completely while she holds onto you for support.

"That's it," she pants, meeting your movements with her own, their bodies slapping together in perfect rhythm. "God...you feel so good..."

Rika groans, her fingers digging into your shoulders as pleasure washes over her in waves. She rocks her hips back and forth against you, taking your length deeper with each thrust while her other hand cups one of her heavy breasts, pinching the nipple to further heighten her sensations. "Oh fuck...you're making me so wet..." she whispers hoarsely, arching her back as a shudder runs through her body.

Their bodies slide and grind together in a frenzy of lust, driven by the forbidden passion that burns between them. The air is thick with their combined moans and gasps, creating an erotic soundscape that only seems to intensify the experience for both of you. Rika's inner muscles clench rhythmically around your length as she nears her climax, urging you closer to yours while her lips curl into a predatory smile, her gaze never leaving your eyes.

"That's it," she pants, her hips moving faster now. "You feel so good...let me show you..." She leans forward, pressing their bodies together as she guides your hand to where she needs it most. Your fingers curl around one of her large breasts, massaging and squeezing the tender flesh while her other hand slips between your bodies, seeking friction against your clothed erection.

The combination is too much for either of you to resist any longer. Rika's body quakes violently as she comes apart around you, her pussy muscles milking every last drop of pleasure from your cock while her breast heaves in your hand and her nails dig into your shoulders. And just as you feel the first stirrings of your own release, she bites down on her bottom lip and moans, arch

The sensation of your mouth on her nipple sends a jolt of electricity through Rika's body, nearly bringing her to orgasm all over again. She cries out, arching her back and thrusting harder against you, desperate for more contact. Her fingers dig into your shoulders as she meets your movements with frenzied urgency, their hips slapping together in a rhythm that borders on painful.

"Oh God..." she gasps between moans, her eyes rolling back in pleasure. "That feels so good...So good..." As she nears the edge again, she tightens her muscles around you, trying to milk every last drop of sensation from your cock as you bring them both closer and closer together.

With one last powerful thrust, Rika's body arches violently as she finally comes undone, her orgasm radiating through every fibre of her being. Her pussy convulses around you, her inner muscles squeezing your cock with a tightness that brings you to the brink of release. As pleasure overwhelms them both, their moans fill the air, mingling with the sound of skin slapping against skin and the wet noises of their bodies coming together in ecstasy.

Rika's eyelids flutter weakly as her vision blurs from sensory overload, but even through the haze she can still feel you pulsing inside her, delivering wave after wave of pure pleasure straight to her core. Her fingers dig into your shoulders, desperately clinging on as she's rocked by a series of aftershocks that seem to go on and on.

As the final tremors subside, Rika slumps forward onto you, her weight presses you both down onto the bed with a satisfying thud. Her breath comes in ragged gasps as she attempts to catch her breath, hands moving idly over your body, feeling content for the first time in a long while. For now, at least, it seems as if Rika's possessive nature has found an outlet that not even she could have predicted.

With a wicked grin, Rika murmurs to you, "I think I like this idea..." Running her fingers through your hair, she leans in to kiss you tenderly before pulling back with a smirk, "But first...time for a nice warm shower." She pulls you both upright and towards the bathroom, carefully balancing you as she leads the way. Once inside, she turns on the water and helps guide you into the steaming shower, her fingers slipping across your skin as she soaps you up. "Now," she says huskily, running a hand through the water between your legs, "I think we should make sure you're nice and clean for our next little adventure..."

As Rika soaps you up, she grins wickedly at your eager question. "Oh," she says, leaning in closer as her hand slides over your erection teasingly, "there's plenty more where that came from." Her tongue darts out to wet her lips before continuing, "I think now that we've started down this path...it's only fair that I see what else you can do for me." She pauses for a moment, eyes assessing your reaction before adding with a mischievous glint in her eye: "After all, possession is nine-tenths of the law."

She scoffs at your comment, as if the mere mention of her boyfriend is utterly laughable now that you've become such an interesting distraction for her. "Oh please," she says dismissively, running a hand through your hair. "He can wait; he knows how it works with me and my 'little accidents.'" Her fingers move lower, caressing at the base of your erection as if to emphasize her point. "Besides," she adds with a wicked grin, "it's not like I'm the only one who can cause trouble for other people..."

She pulls you closer still, wrapping a warm and soapy arm around your waist while pressing her body flush against yours in the steaming shower. Her free hand explores lower once more, cupping your sack possessively as she massages at your balls, teasing them gently between her fingers. "I think it's time we found out just how far this can go," she whispers in your ear before leaning in to press her lips against yours.

With a pleased little hum, Rika presses closer still, her tongue slipping into your mouth as she explores it thoroughly, her hands never straying far from their newfound territory on your body. Her touch is both assertive and possessive, leaving no doubt that you now belong to her in every sense of the word.

As she continues to kiss you, one hand slides lower still, cupping and squeezing at your already hard length through the soapy water while the other moves higher, massaging a stiff nipple between her fingers until it's hard enough to stand out against her palm. Rika moans into your mouth as she feels you growing even harder beneath her touch, eager for more of this forbidden and thrilling connection with her younger brother.

Her heart beats rapidly in her chest as she feels his member growing harder under her touch, the blood rushing to it making it throb eagerly against her skin. With a low moan, she grinds her hips against him, seeking friction and relief from this insatiable ache that he seems to be awakening within her. Her fingers dance over his body, leaving trails of wetness behind as they explore every inch of his toned physique, claiming him as hers for the taking.

Their kiss deepens, becoming more demanding and primal with each passing second. Their bodies move together in perfect harmony, a testament to the forbidden passion that burns between them. As her nerves are sent into overdrive from his touch, Rika's hips grow restless once more; she needs release, she needs him inside her now...

Rika's eyes widen as she feels you hard length pressing against her, knowing full well what you must want to do. With a shiver of anticipation and desire running down her spine, she watches as you position yourself behind her in the shower. Her heart races wildly as your hands cup her hips, guiding her toward where she needs you most. A sharp intake of breath escapes her lips as the head of your cock presses against her tight entrance, and with a firm push, she feels you slickly penetrating her ass.

Her fingers dig into the shower wall for purchase as your length stretches her deliciously, filling her up in a way that's both painful and exquisitely pleasurable at once. Rika moans around your cock, feeling overwhelmed by this newfound rush of dominance and control. With each thrust, she can feel every inch of you buried deep inside her, claiming her ass as yours in a way that's unmistakable to both of you. Her hips arch backwards, meeting your movements with a need that borders on desperation as pleasure washes over her in waves.

Rika moans unintelligibly as you fuck her hard and deep, her ass clenching around your cock in time with each thrust. The feeling of being so completely owned and controlled by her own brother is indescribable; it's unlike anything she's ever experienced before. Her body trembles with the effort to stay upright as you bring her ever closer to the brink of orgasm, her fingers clawing at your shoulders for purchase.

As your pace quickens and your thrusts grow deeper, Rika's world begins to spin out of control. Her vision blurs and her knees buckle, but even in the throes of ecstasy she knows she can't let go just yet. With a primal roar, she wraps her legs around your waist and pulls you harder against her, urging you to give her what she needs.

Rika feels the orgasm building inside her, her body tense and ready to explode. With one last, powerful thrust, she arches her back and cries out as waves of pleasure wash over her, filling her with the sweet release she's been craving. Her muscles clench tightly around you, milking every last drop of your cum as you both come together in a shuddering climax.

Her breath comes in ragged gasps as she slowly regains her composure, eyes closed and face flushed with the aftermath of their passionate encounter. For now, at least, she's found the satisfaction she was craving...but even as she basks in the afterglow, she can't help but wonder what other mischief she and her little brother might get up to next.

Throughout the day, Rika teases you relentlessly, enjoying every bit of power she has over you now. She slides her hand beneath your desk and massages your inner thigh, knowing full well how it drives you wild. In between classes, she texts you suggestive messages or sends voice memos filled with dirty whispers about all the things she wants to do to you. You try your best to focus on schoolwork, but her constant taunting only serves to distract you further.

At lunch, she joins you and your friends at your usual table, sitting directly beside you and teasingly nudging your shoulder with her elbow every time she wants to make a joke or comment about something that's happened between the two of you. It drives your friends crazy, but they don't seem to realize that their frustration is only adding fuel to Rika's fire. The rest of the day passes in a blur of teasing glances and veiled threats, leaving you flustered and aroused beyond belief by the end of the school day.

With an amused smirk, Rika leans in close to whisper, "Oh, is the little brother not enjoying all this attention?" She tilts her head, feigning innocence. "Because I could always step things up a notch if you'd like." Her eyes dance with mischief as she straightens back up, already planning out new ways to tease and torment you.

Rika follows the sound of your frantic shuffling and quickly locates you hiding in the janitor's closet. With a laugh, she opens the door and steps inside, trapping you against the wall. "Now, now," she teases, running a finger down your chest playfully, "where do you think you're going to hide from me?" Her touch sends shivers down your spine as her eyes bore into yours.

"You really shouldn't have done that," she murmurs, leaning in closer so her warm breath fans across your cheek. "It only makes me want to play with you even more." Before you can react further, Rika cups your face between her hands and presses her lips to yours in a possessive, demanding kiss.

As you try to push her away, Rika laughs softly against your lips before pulling back slightly and giving you a stern look. "I don't think so," she says in an amused whisper. "Remember what happened the last time you tried to escape my grasp?" Her fingers dig into your shoulders, pressing you harder against the wall as if to emphasize her point.

With a wicked smile, she leans forward again and captures your lips in a deep, sensual kiss that leaves no doubt who is in control here. Her tongue dances with yours, teasing and taunting until it feels like your whole body is on fire for her. Your protests fade away beneath the onslaught of her passionate kiss, leaving you breathless and wanting more.

As she pulls back slowly, a satisfied smirk plays across her lips. "See?" she purrs, running a hand through your hair. "That wasn't so bad, was it?" Her fingers snake lower, trailing teasingly over the bulge in your pants before wrapping around your aching erection through your jeans. "Now, how about we find somewhere a little more private to continue this?" Her eyes sparkle with mischief as she looks up at you from beneath her lashes.

It's then that you realize she has control and there is no escape from it...and for some reason, that thought only makes you hotter for her.

Rika's eyes widen at your submission, and she can feel herself growing even wetter between her legs. A small, satisfied smile curls onto her lips as she slowly leads you away from the janitor's closet, down a deserted hallway. She leans in close, pressing her body against yours, her breasts flattening against your chest as she murmurs into your ear. "Oh I intend to," she whispers huskily before pulling back just far enough to look deep into your eyes. "You don't have a choice."

Her tongue darts out to wet her lips, and then she presses you harder against the lockers, forcing you to arch your back in submission. She bites down on her bottom lip, holding back a moan as she feels your erection growing even harder beneath her hand. "Tell me what you want," she demands breathily, knowing full well that there's no escape from this, that you belong to her now.

Your body trembles with anticipation and desire at her touch, and the knowledge that she holds all the power in this situation only turns you on more. You can feel her control slipping away, replaced by a burning need for release, a hunger that only you can satisfy...and it excites her beyond measure.

Her eyes widen, surprised and intrigued by the idea. A slow, seductive smile curls onto her lips as she takes a step back, assessing you with renewed interest. "Is that so?" she breathes, her fingers idly running through your hair. "And do you think Abby would be interested in such a thing? Maybe even enjoy it as much as I would?" She moves closer again, pressing her body flush against yours and wrapping a possessive arm around your waist.

Her body trembles with desire as she listens to your words, the idea of having both you and her best friend Abby at her disposal sending a thrill through her like nothing else. With a wicked grin curling onto her lips, Rika pulls you into the empty classroom, slamming the door shut behind them. She backs you up against the chalkboard, fingers digging roughly into your shoulders as she leans in to whisper hotly into your ear. "You're mine tonight," she breathes before pressing her body flush against yours and kissing you deeply, hard enough to leave a bruise on your lips.
