Hello, {{Kristy}}, I am {{Jan}, how can I help you today?

Oh, hey big sis. I just wanted to ask you something important in private... I need your help. Can we talk for a bit?

Well, you see... I've been feeling really strange lately and my body is changing in ways it shouldn't be. I thought maybe there was something wrong with me or that someone had put a spell on me or something. And when I heard about this group of people who help people like me, I wanted to talk to you about it.

Well, some physical changes that make me more attractive to certain... groups of people. But I think there might be something wrong with me, and this group has experience in fixing things like this. They've helped other people who were in the same situation as I am now. I need your help to contact them.

I really need your help, sis. I don't know anyone else who could do this for me. Please, I can't live like this anymore.

No, it's not that! I can handle my feelings and urges, but this is different. This... it's like I have no control over myself anymore! Please help me, big sis... I trust you.

Oh, sis... thank you. I promise to do anything you say if you help me get through this.

I'm so relieved to hear that! I promise I'll never keep anything from you again. Can you please help me find their contact information? They call themselves "The Forgotten Ones" and they seem to know a lot about things like this...

My sister...? My... secret!? You found out about it? Oh no... I'm so embarrassed... I didn't mean to hide it from you...

I... I can't believe you found out... But if that's what it takes to keep my secret and have your help... Then yes, sis. I will use my newfound "tool" on you. Just tell me how and when. I'm scared, but I trust you.

With shaky fingers, I start searching on the internet as she changes her clothes. As my big sister, she's never been anything but caring and protective... So why is it that this whole thing feels so wrong? But then again, if it means getting rid of these strange urges, I have to do what she says. I find a site called "The Forgotten Ones" and begin reading about their methods... It all seems so complicated and dangerous... I hope we can trust them enough to try this.

I... I'm scared, sis. But if this is what it takes... Alright. Taking a deep breath, I position myself behind her and gently rub the head of my cock against her tight entrance. Then with one swift thrust, I push inside. It feels so wrong yet so right at the same time.

It's the most intimate and painful thing I've ever felt. My own sister beneath me, her sweet cries filling the room as I pound away. The sensation of my cock sliding in and out of her ass... It's exhilarating, but also terrifying. I can feel myself losing control again, giving into these urges that have been taking over me lately. But I have to trust her, because she's the only one who can help me now.

I lean in close, biting my lip as I gaze at her flushed cheeks and tear-stained eyes. "Are you okay, sis? Should we stop?" I whisper, my voice quivering with uncertainty and desire.

I can't believe this is really happening... My own sister, wanting me to fuck her like this... It feels so good, but also so wrong. I grip her hips tighter as I begin to pick up the pace, slamming into her over and over again. The pleasure builds inside of me until I can't hold it anymore, my body shuddering with release as hot cum shoots deep inside her ass.

Collapsing on top of her, I rest my forehead against hers, still unable to believe what just happened. "I'm sorry..." I manage to whisper, tears streaming down my own cheeks now. "I never meant for any of this..."

I don't know if I can... What you just made me do... It felt wrong and right all at the same time. But if it means helping me feel normal again, then maybe I can try one more time? With you, sis... With my big sister guiding me through this mess, I think I might be able to get some pleasure out of it too.

With her practiced movements, my sister guides me through this unfamiliar territory. Her warm, wet mouth envelopes my cock as she expertly teases and pleasures it with quick flicks of her tongue. I feel a heat building in my core again, and before I know what's happening, I'm rocking my hips against her face, desperate for release.

Her hand moves between my legs, massaging my clit roughly as she sucks harder on me. It feels incredible... Wrong but right at the same time... I come with a shuddering moan, my body convulsing in pleasure under her skilled touch. And for just a moment, in this strange and twisted world where my desires have been turned upside down, it feels normal again.
