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."

You look at Rika with a mixture of confusion and amusement on your face before speaking in broken English, "Nie musisz sie zasłaniać." In essence, you're telling her that she doesn't have to cover herself up around you. Her cheeks flush even deeper as anger radiates from her body at the words that come out of your mouth. "Shut up," is all she manages to say before lunging forwards and trying again to snatch the phone from your grasp.

This time, you manage to resist her advance slightly better and hold onto the phone tightly while stepping back slightly. "Why are you so bothered? It's just a picture." You grin, taunting her further.

Rika takes a deep breath and exhales slowly, trying to calm herself down before she does something regrettable. "Look, you little brat, I don't want you seeing me like this," she says through gritted teeth. "It means something to me, and you have no right to..." Her voice trails off as anger once again begins to boil beneath the surface.

As soon as those words slip out of your mouth, Rika's eyes go wide with shock and anger. "What did you just say?" she growls, stepping even closer to you. Her face inches from yours as she tries her best to maintain control over the situation. But it's clear that her emotions are running high right now, making it difficult for her to think clearly.

Her left hand leaves her chest exposed slightly in order to point an accusing finger at your face. "You had no right saying that!" She hisses through clenched teeth. You can almost feel the heat coming off of her body as anger takes its hold over every inch of her being.

Rika takes another step closer, her lips pulling back in a snarl as she tries to maintain her composure. "You think that's funny?" She growls, "You think it's cute to say things like that?" Her eyes narrow as she leans even further forward, their faces only inches apart now.

As soon as the word leaves your lips, Rika's anger seems to explode in a flash of fury. Her hand snaps out like a whip and slaps you hard across the face. The force of her blow sends you stumbling backward until you hit the wall behind you. The shock waves from the slap ripple through your body as tears prick at the corners of your eyes, but she doesn't give you time to react.

With another growl, Rika lunges forward and pinches your nose closed with one hand while forcefully pushing her middle finger into your mouth with the other. "You little shit," she hisses venomously, "you don't get to say things like that." She continues to thrust her finger deeper into your mouth as if to make sure you understand just how powerless you truly are in this situation.

As Rika continues to assault you, your anger begins to rise as well. Without really thinking about it, your hand reaches up and grabs her wrists firmly before pulling them away from your face. Her eyes go wide with surprise and rage as she struggles to free herself from your grasp. "Let go of me!" she snarls through gritted teeth.

But you don't let up, tightening your grip on her wrists until she winces in pain. With your other hand, you reach up and cup her breast roughly through the thin fabric of her panties, pinching the nipple hard. "You like it rough, don't you?" You sneer at her as you force her to feel some of the same helplessness she made you experience earlier tonight. Her eyes widen further and a high-pitched moan escapes from between clenched teeth.

As Rika struggles against your grip, her body betrays her when it responds to the touch. The anger that had been fueling her before is replaced by a mixture of confusion and shame as she realizes how easily you've turned the tables on her. She tries to break free again, but it's becoming more and more difficult with every second that passes.

Rika's breath comes in ragged gasps as she continues to fight against your grip. Her whole body trembles with the effort, her nipple growing harder and more sensitive beneath your rough touch. "Stop it," she whispers hoarsely between clenched teeth, tears beginning to well up in her eyes again. "Please." But she knows that this is a part of her that you've always had control over - the parts of her that she's never allowed anyone else to see or touch.

Rika lets out a small whimper as you squeeze her breast even harder, not giving in to her plea for mercy. Tears stream down her face, and she can feel herself growing more and more aroused by the pain and humiliation. She finally gives up, slumping back against the wall with a defeated sigh. "Yes," she whispers hoarsely. "I'll be good."
