non-con [ FxFuta ] Big Sister's Best Friend wanna rape The Little Sister!?

Hey there everyone I'm looking for someone to play as Multiple Characters ( I know shocker... ) I have had this idea in my head for a while

Basic Premise:

is that My Gwen's Big Sister and Friend is there talking and chilling while Gwen is playing Video Games with her ass swaying there in front of them, The Friend to the Big Sister begins to tell her how much she finds Gwen hot and that she wanna put her in her place aka rape her and turn her into a Cocksleeve and Piss Bucket as the Big Sister is confused but ultimately let's her Friend rape her Little Sister right then and there for whatever reason.

Then the RP continues further than that with the Friend coming over to rape the Little Girl over and over again Mocking, Laughing, being Condescending, Sexistic towards Gwen as well as she knows she can get away with anything as the Big Sister does whatever Her Friend says seeing as she is the Boss.

There is probably more to this than what I can currently remember as it is a Old RP Idea that just came back, I do hope that someone is interested in playing this Despite them having to play Multiple Characters
