-Hello. I'm Robbie 28M. I'm new to roleplaying and I never had a good relationship with my sister so this is my way of compensating for that.- ( 'I am 18+ and all participants and characters must be 18+')

TZ: CST.

You and I are a year apart and have always been close. We've had our awkward moments growing up. Our parents would never let us have friends over so we only pretty much had each other. We grew up poor so we slept together in the same room, the same bed. I started sleeping on the couch eventually when I felt we were getting too old for sleeping on the same bed. Presently we are moving to a new state with our parents.

However, in the back of your mind, there is a memory...

It was years ago, back when I was 21 and still in college. I was visiting home and you came by to annoy me as usual. A playful tussle over my phone somehow turned into a wrestling match on our old bed. I had you on your stomach, you were giggling and squirming, trying to tug your wrists off; and then it changed again. I became aroused; I used the weight of my hips to keep you pinned as I ground my erection into your plump bottom. The giggling stopped; your mouth formed a little round O of surprise. After a minute, you started to subtly rock your hips in response. You were encouraging me. I became more frenzied, dry-humping my own sister, unable to stop myself, until with a moan I reached my climax.

Regret followed release. I let you up, mumbled an apology, and beat a hasty retreat. I was terrified you would confront me, denounce me, or, worst of all, never want to see me again.

But none of those things happened. you never told anyone, nor ever spoke to me about it in the years since. Sometimes it almost seems like the whole thing was a dream. Yet sometimes... sometimes... I catch you looking at me in a strange way, or biting your lip, and I imagine you must be thinking about what we did that day.

It's all coming back to you now, and as you pack up the car, part of you can't help but wonder, and even fantasize... ... is it possible that something like that could happen again?

Do you want it to?

In the present, Dad and Mom are moving us across states and we have to stay at a hotel for a few days during our journey. We both grew up thick as thieves being close in age. We've had our awkward moments growing up being curious about each other's bodies. At times we'd wrestle and we'd both enjoy it. As years passed, we never talked about how close we were but kept it to ourselves. I'd subconsciously have crushes on women who looked like you without realizing it.

Once we arrive at the hotel, we learn that the third room was unavailable due to maintenance issues. Our parents ask us to be in the same room instead and not fight over everything. It's been years since we've shared the same bed and having to do it again brought back a lot of 'memories'.

Additional ideas

At first, the situation is mostly awkward and irritating:

  • fighting over blankets
  • changing clothes discreetly
  • trying not to wake each other at night
  • overhearing embarrassing conversations through thin walls
  • pretending not to notice attraction

But as the days pass, the lack of privacy and constant closeness begin affecting us psychologically. Small moments start lingering:

  • accidental touches while squeezing past each other
  • quiet conversations after everyone else falls asleep
  • sharing headphones during late-night movies
  • whispered jokes so family members don’t overhear
  • catching each other staring
  • suppressed frustration turning into tension

-----------------------------------------------------------------------------------

You can continue the plot or have one of your own. Add 'siblove' to your message if you've read this far. I'm hoping for some build up of tension and slow-burn if possible, culminating in both of us giving into our primal urges.

Likes: Risk of being caught, Romance, Sibling incest, Public intimacy, Creampies, Breeding (Anything vanilla)

Limits: Overly sexual, Anal, Piss, Feet, Beast, Gore, stuff not related to the plot would be my hard limits and non negotiable.
