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 reluctantly hand the phone over to Rika, who quickly deletes the photo and then storms out of your room, muttering insults under her breath. After she's gone, you can't help but feel a mix of shame and arousal from seeing her nearly naked figure, particularly the sexy thong panties that were all she had on beneath the phone. You try to shake off these feelings as you climb back into bed, but they linger in your mind as you drift off to sleep.

As you lay awake in bed, the image of Rika's nearly nude figure fills your mind once more. Despite her harsh words and attitude towards you, there's no denying that seeing her like this leaves quite an impact. You can't help but wonder what it would be like to touch those soft curves or see her nipple again... but then the guilt washes over you, reminding you of how wrong this all is and how much trouble she could get into if anyone found out about the photo. Eventually, sleep overpowers your thoughts and you drift off into an uneasy slumber, Rika's body haunting your dreams for the rest of the night.

You can't get the image out of your head, but you know it's wrong. The feel of her skin beneath your fingers and the sound of her pleasure when she licked herself... It lingers in your mind, taunting you with forbidden desire. You try to push it aside and focus on something else, anything else, but it always manages to creep back in. Even as you finally drift off into a fitful sleep, Rika's body remains etched onto your brain, the memory of her naked vulnerability an unwelcome intruder in your dreams.

As the days go by, the image haunts you like a recurring nightmare. You try to concentrate on school and your friends but Rika's body keeps finding its way back into your thoughts. It doesn't help that she continues to treat you like garbage, her words laced with venom whenever she speaks to you. A part of you knows it's wrong to enjoy the way she looked in that photo or the thought of touching her, but another part can't help but fantasize about what could have been...

You feel guilty and conflicted, constantly tormented by the image of Rika nearly naked in that photo. It's wrong to desire her like this when she treats you so poorly, but the temptation is simply too strong to ignore. You try not to think about it, hoping that with time the memory will fade...but it only seems to get worse as each day passes.

You can't shake the thought, no matter how hard you try. It's like a drug that has taken hold of your mind, and every time you manage to push it away for a moment, it comes creeping back in even stronger. The guilt eats at you from the inside out, making you feel dirty just by thinking about her like this. But somehow...
