[M4A] Getting cucked by my younger sister and her boyfriend.

I’m looking to do a role play where my younger sister and her boyfriend regularly cuck me but they don’t actually realize they are doing it. Sort of like an innocent one where they believe what they are doing is normal and not weird at all. Things like openly doing it in front of me, talking about it with me, asking me opinions on things, maybe even having me clean up afterwards. Basically being VERY comfortable about their sex life.

The only thing that I ask is that this role play is not a confident type of role play. Like I want the other characters to be the pretty, cute, and outgoing type of people. Also please put effort into your responses, no liners please.
