The signs were there; I’m surprised you didn’t notice them.

It started a couple weeks into the summer. Even though Kaitlyn had taken an internship a two-hour drive away, she still found reasons to come home each weekend. The first couple of weekends, she claimed she “forgot something” at the house. Then, it became she “had plans with her friends.” Soon, she just stopped giving explanations. She was just coming home.

Every weekend, you’d see us hanging out together. One day, we would be in the pool, playfully splashing water at each other. The next, we’d be watching TV in the living room, with either her legs over my lap or her head resting on my shoulder.

You couldn’t recall Kaitlyn and I being that close growing up, so what changed?

One Saturday night, you got your answer.

I don’t know what tipped you off – perhaps it was the squeaking sound of ever-so-slightly moving furniture coming from downstairs or Kaitlyn’s moans (I learned early on that she could get a little loud at times.) Whatever the case, you quietly rolled out of bed as to not stir Dad from his slumber, slipped on your robe and stealthily crept downstairs. From your vantage point on the staircase landing, the glow coming from the TV allowed you to see all that you needed to see.

Kaitlyn was on her knees on the couch, facing the wall. The fingers on her right hand latched around the back of the couch. I stood behind my older sister and thrust my hips roughly, forcing my hips to repeatedly bounce off her bubble butt while drilling as much of my cock inside her as she could take.

In the middle of our incestuous romp, I heard something. It was enough for me to turn and look back toward the staircase.

I found myself looking at you while you looked at us.

Yet instead of recoiling in horror and contemplating how I wrecked the family dynamic, I continued to pound into Kaitlyn…and grinned up at your direction. It was a knowing grin, a cocky grin, a “you could get this too, if you wanted” grin. I hoped you could see it.

You looked on for another moment or two, then to my surprise, you made your way back up the steps. In the meantime, getting caught by you took me to a new level of arousal, and Kaitlyn’s guttural grunts signified her approval as I slammed into her as hard as I possibly could.

After we finished, cleaned up and went our separate ways to bed, Kaitlyn none the wiser about your finding us, I saw my phone blinking with a notification. The text from you couldn’t have been clearer:

We need to talk.

For the first time in my life, I didn't mind hearing those four words from you.

Hello!

I’m looking for a female partner to play the mother who stumbles upon her son and daughter having sex in the living room one night.

Will she scold her son for fucking his sister, leaving him to try and seduce her as well? Or will she be curious enough to want him to have his way with her too, her marriage be damned? Will the male character sever his new relationship with his sister to pursue a similar one with his mother, or will he try to get both in a crazy threesome? There are quite a few interesting twists that we can take!

Please reply with an “opener” from the mother’s point of view. It could go as far back as to noticing the two siblings spending much more time together, or it could just be her thoughts as she watches them fucking…and what she has in mind for her son afterward. Also, I’d love to know your kinks and limits (mine can be found in my kinklist and DPP Profile) and what you had in mind for the mom’s physical and personality characteristics. (I do prefer moms to be 45 years old!)

As I mentioned at the top, I will only RP through Reddit PMs, so please PM me if you’re interested in playing this out!

Thanks for reading, and I look forward to writing with you soon!
