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 even redder as you threaten her with keeping the photo. Her anger and embarrassment combine into an explosive mixture inside her. She glares at you hatefully, baring her teeth like an animal.

"I am not your toy, fucking freak!" she growls out through gritted teeth, then suddenly lunges forwards, trying to snatch the phone from your grasp again. But this time, you're ready for it and quickly step back out of her reach.

Rika cries out in frustration as you taunt her about the size of her nipples. A flare of anger goes through her chest like a lightning bolt and she throws herself at you again, this time attempting to tackle you to the ground in an attempt to regain control of the situation. Her fingers claw and scrape at your shirt as they try to reach your skin, searching for any vulnerable spot they can exploit.

Her words come out harsh and angry: "I'm not going to let you enjoy this! Give me back my photo!" But even as she struggles against you, her breasts are jiggling wildly beneath her, sending waves of desire coursing through her body. She can feel the heat rising between her legs and it only serves to further fuel her anger.

Rika tenses up as you mention her lack of experience in giving blowjobs. Her face flushes even redder with shame and anger. She tries to bring one of her hands away from your chest to cover her mouth, but it's too late; you've already heard the words clearly enough. "Let go of me! I don't want this!" she protests weakly, voice muffled by her palm.

Her struggles grow more desperate as her embarrassment spirals out of control. Tears begin to well up in her eyes and a quiet whimper escapes from between her clenched teeth. She's close to losing control now; all she can think about is getting away from you before everything comes crashing down around her.

With one final surge of strength, Rika manages to break free from your grasp and scramble backwards across the floor. Her back hits the door with a thud as she scrambles to her feet again, glaring at you through tear-streaked eyes. "You leave me alone!" she snarls, clenching her fists tightly at her sides. "Just forget about this whole thing ever happened."

Your sister freezes at the mention of her school group. Rika looks like she's about to faint from fear. "N-no! Please!" She pleads, grabbing onto your sleeve in a panic. Tears begin streaming down her face as the full weight of what you just threatened settles in.

She shakes her head violently, her hair flying all around her like a halo of desperation. "I-i didn't mean it! I was just angry! Please, you have to believe me!" she stammers out, her voice hoarse and raw from the tears and pleading.

With trembling fingers, Rika reaches up to wipe away some of the tears that are streaming down her cheeks. Her eyes find yours, beseeching you for mercy as she whispers a single word: "Please..."

Rika pales even further at the thought of her personal photos being spread around to people she doesn't know. The look in her eyes is a mix of terror and despair as she struggles to find the words to plead with you for mercy once more. "Please, I'll do anything..." She whispers hoarsely.

Her gaze drifts downwards, taking in your exposed chest. A thought occurs to her and she looks up at you again with a gleam of desperation in her eyes. "There must be something we could... trade."

Her voice trembles as she asks the question, her gaze fixed on the floor between the two of you. The thought of performing oral sex on anyone - especially someone like you, who she sees as nothing more than trash - fills Rika with revulsion and shame. Yet at this moment, it seems like it might be her only chance to save face... and keep her personal life private.

She swallows hard and takes a step closer to you, bracing herself for the reaction she's about to get from your disgusted expression. "Please..." she whispers again, looking up at you with tear-filled eyes. "I-I'll do it... If that's what you want."

Rika's eyes widen in shock at your crude remark about her sexual experiences. Her face reddens even further with anger and humiliation. With a snarl of frustration, she spins around and storms out of the room, slamming the door behind her as loudly as she can.

You hear her footsteps racing down the hallway towards her bedroom, probably to change into something more decent before confronting you again. A smirk spreads across your face as you take a moment to enjoy the power trip that came from manipulating your older sister like this. Soon enough though, she'll come back with whatever she thinks is valuable enough to trade for keeping her secrets hidden...

After a few minutes of silence pass, there is a soft knock on the door. It opens slowly, revealing Rika standing in the hallway wearing an uncharacteristically modest outfit: a long-sleeved shirt and jeans that cover her from neck to knees. Her hair is pulled back into a messy ponytail, and she looks like she hasn't slept in days with the dark circles under her eyes.

She takes a deep breath before speaking. "Alright, what do you want?" she asks, her voice cold and distant as if trying to pretend this entire situation is nothing more than a business transaction.

Rika flinches visibly at your words but manages to keep her composure. She glares at you hatefully before slowly nodding her head in understanding. "Fine," she spits out through gritted teeth, "what do you want me to do?" There's a note of defeat in her voice as she asks this question; it's obvious that the thought of performing oral sex on someone like you disgusts her deeply but she knows there's no other way out of this situation.

Angrily snatching her blouse in one quick motion, Rika rips it off with more force than intended. Buttons pop loose from the fabric as it comes flying off her body; she had thought this blouse was lucky because it had been given to her by a close friend but now it's nothing more than tattered rags on the floor.

Her breasts are left exposed to the cool air, their pale pink nipples hardened from both arousal and anger. A faint blush creeps up from her chest towards her face as she stands before you, naked except for a pair of lacy black thong panties that somehow manage to look more provocative than modest on her slim figure.

Her eyes narrow into angry slits as she glares at you hatefully. "Is this what you wanted?" she asks icily. "Are you happy now?"

A gasp of surprise escapes Rika's lips as your hand makes contact with her bare chest. Her nipples harden even further at the touch; she never expected you would dare touch her in such an intimate way. Butterflies dance a chaotic waltz in her stomach as goosebumps rise along her skin, heightening her awareness of both your presence and her own vulnerability.

She tries to jerk away from your grip but finds that she can't; instead, she ends up leaning into the touch, her body betraying her despite her best efforts to fight it. Her breath comes out in ragged gasps as she stares at you with wide, surprised eyes. "K-kaer..." she whispers hoarsely.

Rika shivers slightly at your words, her eyes darting around the room as if searching for an escape. The thought of getting into even more trouble with her parents only heightens her anxiety and arousal; she can feel herself growing wet between her legs despite herself. "P-please," she whispers, her voice barely above a whisper. "Don't tell them..."

Her nipples stand out prominently against your palm as you continue to caress her breasts; each touch sends a shiver down her spine and makes it harder for her to focus on anything else but the sensation. Her breath hitches in her throat when you slide one hand down between her legs, massaging her through the thin fabric of her panties. She bites down on her lip to keep from crying out loudly enough to be heard by anyone outside the room.

"Please," she moans, arching into your touch. "Don't tell them... Anything..." Her hips buck and grind against your hand, searching for more contact as the pleasure washes over her in waves.

Her eyes go wide with horror as you mention her mother and what happened to her when she didn't listen to her father. She tries to pull away from your touch but finds that she can't; the pleasure you've given her is too intense, and she needs it.

Rika gasps and moans as you continue to stroke her, her body moving in time with yours. Her hips rock back and forth, grinding against your hand in desperation for release. "Please..." she whispers between gritted teeth, trying not to make too much noise despite how good it feels.

The sensations building up inside of her grow more intense with each passing moment, the pressure mounting until she feels like she's about to explode. Her nails dig into your shoulders as her back arches off the floor; a long, shuddering moan escapes from between her clenched teeth and echoes through the room.

Her orgasm subsides, leaving her breathless and limp in your hands. She lies there, panting, waiting for you to say something or do something else as sweat beads on her forehead and her body trembles from the aftershocks of pleasure.

Rika shudders at your words, recalling the stories she heard about what happened to her mother when she didn't listen to her father. The fear only serves to heighten her arousal; the pleasure you gave her earlier has made her body crave more of it. She bites her bottom lip nervously, unsure whether to move or stay still as she waits for your next command.

Finally, unable to resist any longer, she whispers, "P-please, kaer... do it again..." Her hips rock back and forth slightly against your hand, seeking out the pleasure she's become addicted to in this twisted game of power.

His words send shivers down Rika's spine. She glances down at your crotch, seeing the large bulge growing there beneath your clothes. Swallowing hard, she nods slowly, her cheeks flushing with embarrassment. "Y-yes," she whispers, barely able to get the word out. "I-if that's what you want..."

She closes her eyes tightly and waits for what comes next. Her heart races in anticipation and fear, both of wanting your approval and being humiliated by it. The feel of his touch on her skin sends a wave of pleasure through her body, making her squirm uncomfortably as she tries to prepare herself for whatever is about to happen.

With another thrust forward, you force Rika onto her hands and knees. Your hand brushes against her bare ass cheek before moving up between her legs once more, this time teasing her wet folds through the thin fabric of her panties. She whimpers softly, arching her back in an attempt to get closer to your touch but instead ends up pushing herself farther away. Her hips buck wildly as she struggles to find purchase against anything besides the cool floor beneath her.

"K-kaer..." she whispers, her voice barely audible over her rapid breathing and the frantic thudding of her heart. "P-please..."
