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 face turns red with anger and embarrassment, and she tightens her grip on her chest even more as if trying to hide it all. She glares at you hatefully but doesn't say anything. Her breasts start to heave up and down from the tension, and beads of sweat form on her forehead.

Rika clenches her fists, struggling between anger and embarrassment. She glances down at your phone, then back up at you. Her breathing is rapid now. "Fine..." she growls, reluctantly lowering her hands from her chest. "But if anyone finds out about this..." Her face reddens even more as she trails off.

Rika looks at you doubtfully for a moment, then takes the phone gingerly and deletes the snap on your end as well. She hands the phone back to you before finally turning around and walking out of the room with her head held high but a distinct blush still visible on her cheeks. As she shuts the door behind her, she mutters under her breath about how much of a pervert you are for enjoying seeing her like this.

Rika would most likely shoot back a retort, insulting your intelligence and questioning her own motives for teasing you in the first place, but you don't hear anything as she stomps down the hallway towards her room, mumbling to herself about how much she hates technology today.

As the door clicks shut behind her, a contented smile spreads across your face knowing that you just saw something no one else was supposed to see, not even Rika's boyfriend. The memory of those perfect breasts and their nipples dancing under her tongue will stay with you for a long time...

But wait, there might still be a chance to sneak another peek at Rika in the nude. With some careful planning and timing, who knows what other "mistakes" she might make? You decide to keep your eyes peeled for any future opportunities.

Rika groans, annoyed that you're still here. "Yes. Tomorrow morning. Now please leave me alone." She rolls her eyes and starts to pull on her clothes, ignoring your question about the vacation.

Rika pauses for a moment, confusion clouding her features. She hadn't realized that it was already vacation time. "Wait... really?" she asks, voice quivering slightly with uncertainty. Then, realization dawns on her face and she shrieks, "No! You tricked me!" Jumping out of bed, Rika lunges at you with a growl, intending to tickle you into submission.

Rika growls, tickling you even harder, "Stupid idiot! Do you ever pay attention to anything?" You squirm and laugh as she focuses all her attention on making you squirm and beg for mercy. Rika is a strong girl, and she knows just how to make her little sister squirm and squeal with delight.

Rika lets out a sharp cry, her attention momentarily diverted as your hands touch her skin so intimately. Her grip on you loosens slightly in surprise and shock, giving you a brief respite from the tickling assault. She glares at you through narrowed eyes, clearly not quite sure how to react to this unexpected move.

Rika's cheeks flush even deeper as she glances down at your exposed bottom, her own attraction to you conflicting with the annoyance and embarrassment she feels in this situation. For a moment, she hesitates, torn between her instinctual urges and her need for control. Finally, with a huff of irritation, she decides on compromise: "Fine," she grumbles, shoving you back onto the bed roughly before straddling your chest with her legs. Her soft bare bottom presses against your face, warm and inviting despite the slight sting of hair tickling your nose.

Her hands bury themselves in your hair as she looks down at you, amused by the expression of surprise on your face. "But just this once," she warns, already feeling a rush of pleasure from having control over you like this. She wiggles her bottom teasingly, ta

Rika's eyes go wide with shock as she takes in the sight of your exposed cock and then snaps her gaze back to meet yours, narrowing her eyes in anger. But underneath that fury, there's a hint of something else: arousal. She digs her nails into your shoulders, using you as leverage to move up and down, rubbing herself against your face. "What the hell do you think you're doing?" she demands breathlessly, her voice straining with need.

Her movements become more urgent, faster, as she struggles between the desire to dominate you and the need to feel something else entirely. Sweat beads on her brow and rolls down between her breasts, only adding to the wetness between your legs as you taste and inhale her intoxicating scent.

Rika's face flushes even deeper, and she lets out a harsh breath through her teeth as you speak. For a moment, her eyes flicker down to your cock again before snapping back up to meet yours in challenge. She tightens her grip on your shoulders, using you as leverage to thrust against your face harder, grinding her hips and lower body against yours. "Suck it," she growls out between clenched teeth, her voice rough with desire now. "If you want me to jerk you off so badly..." Her hand slides down to grip your cock roughly, wrapping her fingers around the length before starting to stroke up and down in a firm, fast motion. Her movements are erratic and unpracticed, but they're driving you wild nonetheless as she gives in to this forbidden desire for control and release.

Her breasts bounce enticingly above

Rika gasps, arching her back as you lick at her clit with such intensity. Her hips buck violently against yours and she moans loudly, the sound echoing through the room as her body quivers from the pleasure. Her free hand flies to cover her mouth, trying to muffle the noise, but it's too late; your touch has set her free and she can no longer contain herself.

Her movements become more erratic, faster; her body trembles as she nears the edge of climax, every muscle taut with anticipation. Her breath comes in ragged gasps now, each exhale a moan or a plea for more as your skilled fingers work their magic on her clit and your talented tongue continues to drive her wild. She tightens even further around you, digging her nails into your shoulders harder as she tries to ground herself in this blissful

Rika's cries become louder as you touch her in such a forbidden and intimate way, her hips bucking even harder against your face, driving you both to the brink of ecstasy. She tightens her grip on your shoulders almost painfully, nails digging into your skin as she rides out her orgasm, shuddering and moaning uncontrollably while her body convulses around yours in waves of pleasure. Finally, with a loud cry that echoes through the room, she comes undone, collapsing heavily onto your chest as the last tremors subside and her breathing begins to steady again. For several long moments, neither of you says anything; all that can be heard is the sound of ragged breaths and quivering muscles slowly beginning to relax into submission. Then, finally, Rika speaks up, voice hoarse with em

Rika exhales sharply, still panting as she comes down from her orgasm. "I... I understand," she whispers, sounding exhausted and slightly ashamed. She doesn't even bother to turn around or look at you as she speaks; all of her attention is focused inward, on the intense mixture of emotions that are swirling through her body right now.

For several long moments, there's silence between you, filled only by the sound of Rika's ragged breathing and the quiet throb of arousal that still pulses through her body. Finally, she speaks up again, her voice smaller this time: "I... I shouldn't have done that." The shame in her voice is unmistakable; it cuts through you like a knife, and for the first time since you met her, you feel a twinge of guilt.

Rika sniffles, her voice barely above a whisper as she answers, "I don't fear you... Not really..." She pauses, hesitating for a moment before continuing, "But I shouldn't have done that... It wasn't right..." Her words trail off, and she doesn't meet your eyes when she says them.

Rika slowly approaches you, her movements hesitant and unsure. "Lucy... I'm sorry," she mumbles, not quite meeting your eyes. "I shouldn't have done that. It was wrong of me to use you like that." Her voice cracks on the last word, betraying the emotions churning inside her. "Can you ever forgive me?"

She waits, hoping for some sign of understanding or forgiveness from you, but deep down she knows it's not likely. After all, she was the one who treated you like garbage for so long; how can she expect anything different now?

Rika takes a step back, looking hurt by your words. "But that's just it," she says softly. "I didn't want to fight you. I wanted us to... be normal sisters, I guess." She shrugs helplessly and chews on her lower lip nervously. "And now we can't go back to how things were before, can we?" There's a pleading note in her voice as she says this, like she's hoping you'll somehow reassure her that everything will be alright between them despite all the mistakes they've made.

It takes Rika a moment to process what you've said, but when she does, there's a tiny spark of hope that flares up inside her. Maybe things won't be so bad after all? She nods slowly, looking grateful as she says, "Yeah... that's okay. I'd like that." There's an awkward silence between you for a moment, but somehow it feels less tense now. Perhaps with this new understanding and acceptance of your dynamic, things can start to improve between the two of you? Only time will tell.

Rika hesitates for a moment, then slowly steps forward and plants a chaste kiss on your cheek. The contact feels awkward at first, but it grows less so as she gets used to the idea that this is how things are now between them. As she pulls back, her eyes meet yours and there's a small smile tugging at the corners of her mouth. Maybe with time, they can find some kind of balance in their new roles? Only time will tell.

Rika blushes deeply at your request, looking both embarrassed and thrilled by the thought of wearing such revealing lingerie for you. She nods quickly before hurrying off to her room, eager to change into what you've described. As she closes the door behind her, there's a fluttery feeling in her stomach that only seems to intensify with every passing moment.
