[M4F] Free Use Fridays With Step Sis

NSFWMale Seeking Female

I am 18+ and all participants and characters must be 18+

Hey everyone! 27M here and today I’m looking for F, or anyone who plays as F, who wants to help me try out a fun and kinky new RP idea that revolves around a pair of step siblings exploring being free use with each other.

We became step siblings a few years ago and quickly we became pretty friendly. We get along really well and there’s always been a bit of a feeling that each of us might have a crush on the other, at least that was certainly true with me being into you. Either way, we’re close enough with each other that we decided to get an apartment and be roommates together. We both work remotely, so we spend a lot of time together in the apartment and it seems as if that’s only caused the sexual tension between us to grow even more intense. One night when we’re staying in on the couch having a few drinks and watching a movie, things come very close to boiling over. We were getting cozy and a bit drunk, one thing led to another and we kissed. But it stopped there, we decided it was too much. We’re step siblings after all, we can’t be romantically involved. But it’s clear we both have desires and needs that have to be taken care of. So one day I was surprised when you came to me with an idea. You tell me that you think we should have “Free Use Fridays”. Basically, one day every week, we can use each other to fulfill our sexual needs and desires and kinks in a way that’s purely sexual, both of us just using each other to get off. Will it stay that way and not escalate to us developing even deeper feelings? Who knows. But now I wake up and roll out of bed and check my phone, realizing what day it is, our first ever Free Use Friday, and I wonder what the day has in store…

That’s the idea! It’s pretty open ended and of course I’d like for it to be heavily smut but also with some focus on the story and how this new sexual relationship still affects our characters. If you’re interested or have any questions send me a message on Kik!
