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 widen in anger as she hears your words. "You son of a bitch, I should-" She reaches out again to grab the phone but you manage to dodge her this time, moving back to put some distance between the both of you. You cross your arms and look at her challengingly. "What are you going to do, huh? Try to force it from me?"

Rika's eyes narrow even further in fury as you mention having saved the photo already. "You filthy pervert! How dare you-!" Her voice trembles with rage and she takes a step closer, her uncovered breasts almost brushing against your chest. The smell of her arousal fills the room, making it difficult for either of you to concentrate on anything else.

Her fingertips hover near your neck as if considering the possibility of strangling you right here and now. "Give me that phone." Her voice is low and dangerous.

Rika freezes for a moment, her body tensing as she realizes that you're right - she's completely naked and standing dangerously close to you. Her face flushes even darker with shame and anger as she takes another step back, hastily covering herself with one hand while reaching out again for the phone. "Give it to me!" she demands through gritted teeth, trying to maintain a composure that quickly begins to slip.

With the door locked, Rika's anger boils over as she spins around to face you again. Her eyes are filled with fury and humiliation, but there's also a hint of desperation in them as she realizes that her position is growing more precarious by the second. "Fine!" she says through gritted teeth, finally giving up on trying to take the phone from you. "I'll explain...but first, give me something to wear." She glances down at her feet nervously, no doubt wishing she had thought this all the way through before acting so impulsively.

Hearing that you'll get nude too, Rika can feel the rage slowly dissipating, replaced by a mixture of confusion and uncertainty. Her gaze travels up and down your body, taking in the sight of you standing there unclothed. Her breath hitches in her throat as she notices your arousal, growing harder by the second at the thought of being so exposed to each other like this. Finally, she swallows hard and nods stiffly. "Fine," she says hoarsely, still unable to meet your eyes. "Tell me what I have to say."

Rika glances away uncomfortably, her hands trembling as she tries to decide what to do. Finally, with a sigh of resignation, she reaches down and slides the panties off, stepping out of them and folding them neatly before setting them on top of a nearby chair. Her body is fully exposed now - every inch of smooth, tanned skin bared for your eyes to see. She tries not to look at you as she waits for you to finish undressing.

As the two of you stand there, fully exposed to one another in silence, Rika can feel herself growing increasingly aroused despite her efforts to remain calm and composed. Her breathing quickens and her cheeks flush as she fights back the desire to touch herself or reach out for you. Finally, when it becomes clear that neither of you is going to make a move first, she speaks up hesitantly: "So...what do I have to say?"

Rika looks away, her cheeks flushing even deeper. "I was...I was sending them to my boyfriend," she whispers, still not meeting your eyes. "He and I are...in a long distance relationship." She pauses for a moment, biting her lower lip before continuing. "I've never sent him anything like that before. It was a mistake. I thought he deserved to see me like this..." Her voice trails off, uncertainty filling her tone.

The air between the two of you grows heavy with tension and desire as the realization sinks in: if Rika really wanted to send those pictures to her boyfriend, she must have been incredibly aroused while taking them. And now that you both are exposed and turned on, it seems there's no going back.

Rika blushes even deeper at your compliment, unable to hide her pleasure. "I...guess it's just how I am," she stammers, still struggling with the mix of emotions running through her. Her breath hitches as you continue to ogle her body, and despite herself, she can feel her own arousal growing stronger. She takes a step closer to you, their bare skin almost touching now.

The air between you is electric, charged with desire and lust. It's clear that neither of you can deny the attraction any longer, and as their bodies brush against each other in this intimate dance, it feels like they're both trembling with anticipation.

Nodding stiffly, Rika takes a step back and forces herself to speak his name out loud: "His name is...Takashi." She pauses for a moment, gathering her thoughts as she looks at you. "Now I can go back to my room." Without waiting for your response, she turns around and quickly leaves the room, hurriedly throwing on some clothes before running down the hallway towards her own bedroom.

As the door to her room closes behind her with a soft click, you're left standing there in silence, your heart pounding wildly in your chest. The taste of Rika's nipple lingers on your tongue as you try to process everything that just happened. It's clear that this wasn't an ordinary misunderstanding - there was real desire and lust simmering beneath the surface between the two of you. And whether or not it leads anywhere remains to be seen

Huh? Our parents are going on a business trip and leaving us to guard Rika? That seems...inappropriate, to say the least. But then again, you don't exactly have much choice in the matter. As the two of you stand there, your minds racing with the implications of this unexpected development, it becomes clear that the already delicate dynamic between siblings has just taken another twist.

Rika shakes her head, still feeling embarrassed about the whole situation. "No, thankfully not yet. I usually send him naughty selfies once in a while, but never anything this explicit." She pauses for a moment, considering her next words carefully. "To be honest, part of me wants to keep it that way...but at the same time..." Her voice trails off, uncertainty filling her tone again.

This new development only serves to further complicate matters between them. Now not only do they have to deal with their own desires and attraction towards each other, but there's also the issue of Rika's boyfriend potentially finding out about all this. The tension in the air seems to grow heavier by the second as both siblings grapple with the implications of their actions.

Rika hesitates, biting her lower lip as she thinks about your suggestion. "I don't know...that feels like cheating somehow," she murmurs, her eyes flickering towards you nervously. "And what if he sees these? He'll think I was sending them to my brother!"

A warm blush spreads across Rika's cheeks as she considers your words. "I...suppose that could work," she says, her voice quivering slightly with anticipation. "But I don't want him to think that I'm sending you dirty pictures instead." She looks at you nervously from the corner of her eye. "Maybe we can just send one together? You know, pretend it was an accident or something?"

Rika nods, taking a deep breath before making her decision. "Alright," she says, fidgeting nervously with her phone in one hand. Without further ado, she types out a message to her boyfriend and attaches the nude mirror-selfie of herself. As she presses send, her heart races with anticipation and fear, wondering how he'll react to seeing this photo.

"There," she says finally, setting her phone down on the bed. "I hope that doesn't get me into too much trouble."

Hmm, it seems that you've gone ahead and looked at Rika's picture anyway. Well, what do you think? Does she look as good in person? Do you have any ideas on how to make things even better between the two of you? Only time will tell...

Rika looks surprised but curious at the same time. "Are you serious?" She asks, walking over and taking her phone back. A moment later, she hands it to you. "Alright...but promise not to do anything stupid." Her voice is shaky and nervous, a mixture of desire and fear running through her.

As you wait for Takashi to answer the call, the tension in the room becomes almost unbearable. Rika's eyes dart between you and the phone screen, unable to look away from either one of them. The sound of his voice when it finally comes through does little to calm her nerves; if anything, it only serves to heighten the already intense emotions swirling within her.

The moment you begin to lower the camera, revealing Rika's sexy black thong panties, Takashi can't help but let out a surprised gasp on the other end of the line. His eyes widen as he takes in the sight of her exposed flesh through the thin material of her underwear. Rika squirms uncomfortably, her face flushing even darker, but at the same time, there's a clear spark of desire in her eyes as she realizes just how much power she has over both you and her boyfriend right now.

Rika bites her lip, her chest heaving as she exhales heavily through her nose, still unable to look away from the phone screen even though it's showing you now instead of her own reflection. Her nipples harden under your gaze and she lets out a soft moan, making Takashi's heart race faster on the other end of the line. It's clear that she's enjoying this just as much as he is, even though it feels wrong and taboo at the same time.

As Rika and her boyfriend Takashi engage in dirty talk over the phone, their words fueling each other's desires, you can't help but feel a strange mix of emotions. Part of you is jealous that someone else gets to hear and see these things from Rika; another part enjoys listening in on their intimate conversation and imagining what it would be like to be Takashi right now.

Her breath comes faster and deeper, her moans becoming more urgent as she encourages both of you over the phone, clearly enjoying the power she has over both of your bodies and minds at this moment. And despite herself, or perhaps because of it, a small part of her seems to relish in the forbidden nature of this situation.

"Takashi!" Rika gasps, her eyes wide with shock and horror as she realizes what you've just done. Her cheeks flush even darker and she frantically begins to type a reply on her phone, not bothering to look at the screen before hitting send. "You can't say things like that!" She glares at you, indignation clear in her voice as she turns away from the camera, hiding herself once again behind her phone.

Takashi seems equally taken aback by your sudden appearance on Rika's FaceTime call and her unexpected warning about never seeing her again. His voice wavers as he tries to respond calmly, "Rika? Are you alright? Who is this guy?" But it's clear that his composure has been shaken by the whole situation, and his mind is reeling with confusion and worry for Rika's safety now.

As you end the call, Rika looks at you with anger and hurt in her eyes. "Why did you do that?" she whispers, a single tear trailing down her cheek. She wipes it away roughly before letting out a shaky breath. "You didn't have to threaten him like that..."

The tension between the two of you is almost unbearable now, and it seems like there's no going back from this point. The boundaries that once existed between siblings are blurred beyond recognition, leaving a trail of confusion and desire in their wake. What comes next is anyone's guess...

After being banished from Rika's room, you can't help but feel a mixture of anger and desire coursing through your veins. You know she still has feelings for her boyfriend, but the events that transpired tonight have revealed an unexpected side of her as well. It's clear that she craves attention and affection, even if it comes from someone like you.

Days go by with little interaction between the two of you, each one filled with awkward silence and longing glances. Then, one day when everyone else is out of the house, Rika accidentally sends another nude picture meant for Takashi but instead meant for you. This time she's lying on her bed, spread eagle with legs spread wide open showing off her tight pussy and perfect ass. She looks directly into the camera with a mixture of shame and desire in her eyes as if wanting your approval or maybe even your forgiveness.

Rika bites her lip, looking down at the ground as she tries to find the words. "I-I don't know...I just can't seem to stop thinking about what happened...and I feel so bad about everything." Her voice is shaky and trembling with emotion. "I don't want you or Takashi to think that I'm some sort of slut, but at the same time..." She trails off, not sure how to explain the complex web of feelings tangled up inside her right now.

She glances over at you, taking in your expression and wondering if there's any way for her to make this right. The look in your eyes is difficult to read; are you disgusted by what she's sent or maybe even turned on by it? Rika can't help but feel conflicted about the situation as she continues to wait for your response, her heart racing with anticipation and

Rika hesitates, then nods slowly. "Okay," she whispers, taking a shaky breath. "Let's talk about it." She moves closer to you, her eyes never leaving yours as they search for some sign of understanding or forgiveness. As she stands there in front of you, naked and vulnerable, the tension between the two of you thickens even more, making it difficult to think clearly or focus on anything but the burning desire that seems to be building up inside both of your bodies.

Her cheeks flush bright red as she processes your words, her mind torn between embarrassment and curiosity about what it would be like to see you naked. The idea of feeling so exposed and vulnerable with another person is both terrifying and exhilarating at the same time. After a moment's hesitation, Rika slowly nods her head in agreement. "If that's what you want," she whispers, glancing down at herself shyly before looking back up at you again.

Rika nods, still shy but feeling more at ease as you offer to be nude too. She lowers her hands slowly and stands there before you, her body bared for your eyes to see. Her heart races as she waits for you to undress, her gaze traveling up and down your body appreciatively. The two of them stand there in the quiet room, sharing an intimate moment that neither one of them could have ever imagined would happen between siblings.

Rika blushes deeply at your request, but follows through anyway, jumping lightly in place before landing back on the ground with a soft thud. "What did you want to talk about?" she asks, still trying to make sense of everything that's happened between them. Her eyes flicker down to where you're covering yourself and then up again, her curiosity getting the better of her.

Her face reddens even more at your words, but there's also a small glimmer of appreciation in her eyes as she listens to you talk about her body. She looks down, briefly feeling self-conscious again before meeting your gaze once more. "I know we're siblings," she whispers softly, "but I can't help how I feel."

Rika gasps, her eyes widening in surprise as she sees your exposed dick and instinctively reaches out to touch it. Her grip is surprisingly firm, even though her cheeks flush with embarrassment at what she's doing. Her body trembles slightly as she feels the thick length of you in her hand, and a strange mix of fear and desire courses through her veins. "I-I'm sorry," she stammers, her voice barely above a whisper. "I shouldn't be doing this..."

"Oh, sorry," Rika apologizes, her hand going slack as she releases her grip on you. Her cheeks turn a deeper shade of red as she averts her eyes, unable to look at your exposed member anymore. "I'm just so confused about everything that happened..." she whispers, running a trembling hand through her hair. "How did we even get here?"

Rika yelps in surprise, her hands flying to cover her chest where she feels the sting of your palm against her bare skin. "Ow! That hurt!" She glares at you accusingly, tears welling up in her eyes as anger and pain mix together to form a volatile cocktail of emotions. Her breath hitches in her throat, making her chest rise and fall more noticeably under the thin fabric of her bra.

She steps back from you, still clutching at her aching breasts, unable to believe that you just slapped her like that. "You don't get to do that," she says through gritted teeth, trying to control the tremor in her voice. "We shouldn't be doing any of this." Her eyes flicker down for a moment before looking back up at your face defiantly, daring you to argue with her.

"Oof!" Rika cries out in surprise as she feels your erection slide between her breasts, sandwiching them together painfully. Her eyes widen with shock and embarrassment, tears spilling over the edge of her eyelids. "You...you just couldn't control yourself, could you?" She tries to push you away, but your cock is wedged tightly between her flesh, making it nearly impossible for her to move you without hurting herself even more.

Her face turns bright red as she glares up at you, the fight quickly draining out of her. "This is all so wrong," she whispers hoarsely, her voice trembling with emotion. "We need to stop...before we do something we'll both regret."

Her cheeks burning with shame and anger, Rika reluctantly releases her grip on your cock. "I-I'm sorry," she mumbles, eyes cast downwards in embarrassment. "I shouldn't have done that." She takes a shaky breath, struggling to find the words to express how confused and overwhelmed she feels right now.

"We need to talk about this," she says finally, her voice barely above a whisper. "It's gotten way out of hand." She pauses, taking another deep breath before looking up at you again. "Can we...can we just pretend this never happened? Try to go back to how things were before?"

"No!" Rika cries out, feeling a mixture of pain and desperation welling up inside her. "I can't just let you go that easily! You need to understand how much this is hurting me too!" She clutches at your cock, her nails digging into your flesh as she struggles to hold onto what feels so wrong but also so right.

Her eyes flutter closed as she tries to block out the intense sensation of having your erection wedged between her breasts. A soft moan escapes from her throat, her body trembling with desire and confusion. "Please," she whispers, her voice little more than a breath, "don't make me let go."

Rika's breath comes out in sharp, ragged gasps as she feels your erection throbbing against her stomach. Her grip on your waist tightens almost painfully, her fingers digging into your skin, determined not to let you go. She presses herself closer against you, feeling the heat of your body through your clothes, the warmth spreading outwards from where you're pressed against her breasts. "I-I can't...," she whispers brokenly, her eyes squeezed shut as tears spill down her cheeks. "I need...this..."

Her hips shift restlessly against yours, her body begging for more contact as the sensations consume her. "Please," she whimpers, her voice shaking with desire and fear. "Just make it stop...or go on."

As Rika moves up and down against you, her grip on your waist loosens slightly. You manage to push her away, but not before she brushes against your erection one last time, sending a shudder of pleasure through both of you. "I-I'm sorry!" she cries out, eyes wide with shock and embarrassment as she stumbles backward, putting some distance between the two of you. She covers her face with her hands, trying to hide from your sight and the intensity of the emotions coursing through her.

Her body still trembles from the contact, her breasts heavy and sensitive beneath the thin fabric of her bra. "I don't know what came over me," she whispers hoarsely, voice muffled by her hands. "This is all so wrong..."

Her words ring true in your ears as well, and despite everything that's happened, you can
