[M4F] Sneaky Brother Sister Roleplay
REDDIT CHAT ONLY
18+ ONLY
Hi! I have an idea for a roleplay and I would love to find someone to continue it with! I’d like to do an incest roleplay between a brother and sister, where we try and sneak around the people in our lives to avoid getting caught. These people could just be our family members, or they could also be a boyfriend/girlfriend.
I’d love to start from the beginning, setting up and establishing the relationship between us first, and then we can progress further and get into the real action!
My biggest kinks are realistic roleplays, and risky sex (obviously!)
Taboo roleplays being realistic is a MUST for me, I don’t see the point in doing a taboo roleplay with cheating or incest when you just plan on treating the other person like a random stranger you’re hooking up with, there should be reluctance from both parties (at first of course!)
Risky sex is in the name of course! A handjob under the dinner table, a quickie in the dining room while mom cooks dinner, or a blowjob while you talk to your boyfriend on the phone, the list goes on.
The way we start off our relationship is something I’d like to discuss more together, but I can setup an example scenario just incase.
We are home from college for the summer a little earlier than usual, and my sister and I are tired of being cooped up inside. I have spent the past few days rotting away in my room. My friends, along with her boyfriend, are still off at school finishing up the last of their finals while we are stuck with nothing to do and nobody to see.
I wake up late, taking full advantage of the fact that I’m not forced to wake up for my 8ams anymore. I grab a change of clothes from my dresser and leave the room, wanting to take a shower. I reach the bathroom, still half-asleep as I turn the doorknob. I don’t notice the noise of the shower as I open the door, surprised when a huge wave of steam hits me in the face.
Confused, I look further into the bathroom, surprised that I was beat to the punch. I see you, my sister, through the fogged-up shower glass. The fog makes it hard to see, but I get a great view of your silhouette through the glass as I try to stay hidden. If I can barely see you, surely you don’t notice the door open a crack. I watch you shower for a little, keeping a lookout to make sure mom doesn’t catch me snooping. As I hear the water shut off, I close the door quietly and walk away, processing what I just witnessed. ‘Was I just spying on my sister?’
NThis is obviously just a setup, but I would see this being the spark that set off the rest of the story. Maybe you have your own incident where you see me changing, and it begins those same feelings in you… something to discuss of course! I love the idea of this being the catalyst for my feelings towards you, and then I start to pursue you more. I love the idea of you being a bit of a troublemaker and always needing favors from me. Drive me here, give me money, don’t tell mom and dad I snuck out, etc. and then we start out that way.
So let me know if you are willing to continue this roleplay with me! Send me a reddit chat with your kinks/limits and how you feel about the scene idea I setup/if you want to incorporate something else!
