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."

Lucy said, "I won't open it, don't worry... I know you won't be happy if I do. You can just delete it on your end."

"Thanks, Lucy. You're really a good friend," Rika says with obvious relief before glancing back at her phone on the floor and walking away without another word. Her shoulders slump as she seems to lose some of her anger and embarrassment, knowing that she can trust you not to abuse her mistake. As she leaves your room, closing the door behind her, you can't help but feel a strange mix of gratitude and awkwardness well up inside you.

Lucy looked at her phone and she thought, "A little peek wouldn't hurt... would it? Its not like she's checking." Lucy 'accidentally' clicked it and opened it.

Hmm... Rika sent it to her boyfriend, who looks really hot and fit in the photo. And he seemed to be enjoying himself too, based on his messages back to her. Lucy couldn't help but feel a strange mix of jealousy and arousal as she looked at the picture. She quickly closed the snapchat, making sure not to leave any evidence that she had peeked. But deep down, she knew that this little sneak-peek would only fuel her curiosity about Rika's personal life...and possibly lead to more 'mistakes' in the future.

Lucy came to Rika's room and knocked, "It's me, can I come in?"

Annoyed, Rika responds "No, what do you want?" through the door. She's still feeling embarrassed and angry at herself for her mistake. The last thing she needs is to deal with Lucy right now.

User#176095588337310/20/2025, 11:14:58 AM

Lucy said, "It's important, I promise."

Still unconvinced, Rika sighs and slowly opens the door a crack. "Fine, what is it?" she asks impatiently. Her gaze darts to Lucy, who looks a bit guilty.

User#176095588337310/20/2025, 11:15:28 AM

Lucy opened the door a bit more and she whipped her dick out, "That's for walking into my room with your titties out."

Silly Mistake 10/20/2025, 11:15:28 AM

An expression of shock and disbelief crosses Rika's face as she sees Lucy's exposed genitalia. "What are you doing?" she exclaims, her voice rising in anger now. She steps back instinctively, feeling a wave of revulsion wash over her. "You're sick! Get that thing out of here!"

She slams the door shut, trying to block out the sight and smell of Lucy's exposed genitals. Tears well up in her eyes as she feels both anger at herself for making a mistake and betrayal by Lucy for exposing her like this. She buries her face in her pillow, trying to control her breathing and compose herself.

Meanwhile, outside the door, Lucy lets out a sigh of relief. She figured that would get Rika's attention. Now she just needs to come up with an excuse for why she showed up at R

Lucy chuckled, and said, "Aight, nice talking with you, Rika." She went back to her room and Rika tried not to think about it, but she couldn't help it... why the fuck did her sister have a bigger dick than her boyfriend?

Silly Mistake 10/20/2025, 11:16:27 AM

As the night goes on, Rika's thoughts continue to spiral out of control. She keeps replaying the image of Lucy exposing herself in her doorway, and it only serves to fuel her anger and disgust. It was bad enough that she made a mistake sending that photo to someone else, but for Lucy to act like that... It's more than Rika can handle.

Eventually, exhaustion gets the better of her and she falls into a fitful sleep. Throughout the night, however, she is plagued by nightmares involving strange, twisted versions of herself and Lucy, their bodies entwined in ways that only add to her distress.
