When I ordered the silly little Ancestry kit online, it was just for a laugh. A friend of mine had done it - and found out she had originating DNA from all over the world, and it gave her funny little insights into her DNA. That's all it was supposed to be. A laugh. A joke.

Instead, it turned my world upside down.

I sent the spit off in the tube and a couple of weeks later, I got my results. At first, it was all fun - seeing my Scottish heritage, some of the 'traits' it prescribed me, things like that. Out of curiosity, I checked my DNA matches.

That's when I saw you. A 25% DNA match. A half sibling.

I didn't understand it. My parents had been married since they were both 21. They'd never split up. They'd never spent a night apart. I felt nauseous. I was your.... your half-sister? Your 24-year old half-sister who you knew nothing about?

I took a couple of days to process things. I talked to my friends about it. They were uncomfortable, and tried to shrug it off. I don't know why I expected otherwise.

So, I decided to reach out through the Ancestry app.

"Hi there,

I'm sorry if this message is weird and out of the blue. My name is Abigail. I don't even know if you still have this app installed or when you did your test. But I just did mine a couple of weeks ago and got my results back, and I saw we're a 25% match (which means we're half-siblings, I think).

I know it's probably super fucking weird to read that and I promise you I'm freaked out too. You're not obliged to answer me but I'd love to get to know you and figure out... I dunno. Anything?

I don't even know if we live in the same country, city, anything. But I'm in Dublin, in Ireland. I'm 24, and... I dunno. Maybe we can save the rest for an actual talk? A phone call or maybe even in person?

I'm sorry if I've rambled. Sorry if this message ruins your day, or life. Feel free to ignore me, or send me a text, a call, anything - my number is ''xxxxxxx'.

Abi x"

(Thanks for reading! Simple enough premise I think, would love to hear your ideas or a straight continuation. Please be literate - I'll ignore messages riddled with errors and lazy efforts. That doesn't mean you need to send novellas, but let's give each other something to work with.

Limits: Scat, piss, extreme BDSM, unrealistic penis sizes, sounding.)

"Ungh! Yes! Just like that." I moan, feeling my date from last night slam into her from behind. The date had gone horribly - he was an absolute airhead, but I was leaving campus soon, and he was hot, so I let him stay the night.

My moans continue, as does the sound of him sliding in and out of my wet cunt. My phone buzzed on my bedside locker and I looked to it. "Oh fuck." I say, scrambling my hand towards it and picking it up. I look back at the idiot who was inside of me. "Keep going but... Mmph! Keep quiet." I warn him, shooting him a glare.

"Hey sis," I say, while my date kept fucking me, his hands on my hips.

"Hey Megan! How's things?" Rachel, her older sister responds.

"Oh, you know... " I muse. She muted the phone for a second and moaned loudly, before unmuting. "Same old."

"Yeah, good. Um, listen. So obviously, we bought the house last year. We've just finished renovations, well, a couple of weeks ago. I was wondering if you'd wanna stay for a while, over your summer break? We haven't had much of a chance to see each other in the last couple of years and, well, I miss you!" Rachel says, beaming as she speaks on the phone.

"Oh, Rachel..." I say, a smile on my face, unrelated to the pounding I was taking. "That sounds fantastic. I'm just in the middle of a workout, can I call you back later to arrange specifics?" I say, cheerily.

"Yeah, of course!" my sister responds, and I hung up the phone.

"Ungh!" I moan, her date still pounding her. She looked back to him. "Can you fucking cum already?" I moan, and start to rock my hips against him. The look on his face says it all, and seconds later... A loud moan, and he collapses on top of my back, filling me with his seed.

I called her sister later to arrange my stay. I finished my Uni semester on a Friday, so I'd get the plane home that morning, and Rachel would collect mre from the airport. Rachel's partner had prepared the guest room for me, so there was plenty of space for me to stay. I was excited.

I was a different girl when I left home for Uni. I used to be quiet, reserved, unconfident, with no sense of style or fashion. Now?

Now I knew every eye drifted to me in every room that I walked into. I could wrap any man or woman around my fingers as I pleased. Now, I was used to getting what I wanted. I liked to create chaos for the sake of it, and didn't care what that might entail - even if it meant somebody got hurt.

I wondered what life would be like for the summer with my sister and her sister's partner - would it be boring, after the fun couple of years spent abroad at Uni, or would I find ways to entertain myself?

Rachel and I enjoy our hour long chat in the car, giggling to each other, reminiscing, and talking about some plans they'd make for the summer. Rachel works as a nurse so would be out of the house often, but assured me that her partner would be around most days if I needed anything. I knew you, of course. You'd been with Rachel since I was barely a teenager, and you were practically family.

"I'll go get you some help with those bags..." Rachel says, as the car pulls into the driveway. She opens the boot of the car and takes her shopping bags out of the back - groceries for the week, and makes her way into the house.

"Hey, you," She says with a smile, giving you a kiss on the cheek. "Megan is out at the car, getting her bags - can you give her a hand? It's a couple of suitcases but I think they're heavy."

(Thank you for reading! So, I'm looking for a slow-burn RP here, where an affair starts between Megan (my character - and yes, not my real name, just the character's name), and yours, the partner of my sister. I have a description and reference in mind for my character, and I'm also happy to adjust for your preferences. I'd love you to respond with a continuation, but feel free to ask any questions. If you saw me post this yesterday with the wrong title - no you didn't.

Hope to hear from you.)

My 18th birthday was a fun night. My friends and I spent the first few hours of the evening drinking in my house - we had food, we danced, we took pictures, it was everything I wanted. Lowkey, minimal, perfect. Around 8PM, we left the house, and walked to the local pub. I'd been in before - with my parents, during the day, or the odd time when there was no bouncer on the door and I could sneak in for a couple.

Tonight, though? It got messy. I was the last of the group to turn 18. The second we got into the pub, we started ordering shots. Spirits flew freely, strangers joined our group, and the night became a blurry haze. The last thing I remember is being with my friend, Amy, and trying to convince her to get a taxi him. Then? We did more Sambuca.

Fast forward to now. The pub is mostly empty. My friends have no idea where I am. My phone is missing. And me? I'm unconscious. Passed out in the men's bathroom, bent over a sink. My green dress clings tightly to me, ending just below my arse cheeks, my dark blonde hair fallen in a curtain over my face.

And what will you do when you walk in and see me? Will you be the good Samaritan who helps? Or have you something else in mind?

"Ungh! Yes! Just like that." I moan, feeling my date from last night slam into her from behind. The date had gone horribly - he was an absolute airhead, but I was leaving campus soon, and he was hot, so I let him stay the night.
