You (my twin sister) and I stumbled back to the apartment we share with our younger sister very late last night. We had both been drinking heavily, needing to support one another as we came through the door.

Our sister was waiting for us on the couch when we got there, looking rather upset.

“Really?” She asked us sounding rather exasperated. “Again, you guys went out without me again?”

Both of us tried to answer. We tried to form some manner of coherent sentence, to try and explain how we had just forgotten or that she just wasn’t around when we made the plan. But we were too drunk to do even that. Not that she would have bought that excuse again anyway.

She waved away our drunken attempts at an explanation with a sigh as she bolted up to her feet.

“Ya know, since you two never want to leave one another’s side, since you never want to include anyone else in your plans, I’ll make sure you never have to worry about anyone else ever again.” And then she punctuated her somewhat ominous statement, by storming off down the hall, slamming her door behind her.

We then stumbled off to our respective rooms, trying not to think much about how upset she probably was. Promptly passing out, not waking until morning.

Unknown to us though, after the last time this had happened, our sister had done a deep dive into witchcraft, looking for the means to punish us, should we ever do something like this again. And boy had she ever found a way. We’d truly never be able to leave one another alone after this. For the spell she planned on casting tonight would throw us into a never ending lust for one another. We’d never be able to pull ourselves apart from one another after tonight, simply going from one explosive orgasm to the next as we descended into eternal pit of never ending incestuous depravity.

Kinks:

Incest, Cumplay, creampies, dirty talk, clothed sex, public sex, neediness, desperation, anal, oral, vaginal, rimming, lots of cum, sex-a-thons, and much much more. If it’s not a limit, just ask!

Limits:

Gore, feet, toilet play, animals, non con

Anywho, I think you get the point! Looking to dive into an idea where my twin sister and I are cursed into a never ending fuck fest. With only our younger sister holding the key to being able to stop it. Not that she’s planning on doing so.

I know I typed it out in first person, but I am comfortable in first or third, based on your preference.

We can play this out as a short term idea or something longer, again depending on your preference.

And finally, we can do this either here on Reddit (in PMs, not chats) or another platform depending on your comfort level with that.

If you’re interested, just shoot me a message. Feel free to ask questions, clarify things as needed, or make suggestions or changes based on your style.

Hope to hear from you soon!
