I am looking for 4 four people [2fubs, 2msubs].As it is an incest themed roleplay,those who find it annoying are welcome to read.. If you choose to participate,feel free to dm me with your kinks and limits. Each roleplayer will be vetted thoroughly by me.

...............……................................................

I[21M] live with his roommate A.We have been friends for years and know each other's families well. Being childhood friends, we had decided to go to college together and live together to save on rent. We got settled into our new house and pretty soon we were busy in life. One fine afternoon , I drop by the apartment to get a change of clothes.I quietly get into the apartment in order to not disrupt A's sleep. I take a peek into his ajar bedroom and am just shocked at what I am seeing. I see my childhood best friend jerking to my shirtless picture,but there's also something else I noticed a little pink chastity cage near the bed!.....[A lot of conversations later,he decides to become my submissive]. .....................................................................

It has now been about 5 months since A has started serving as my submissive and life has been good. It was now Christmas and the festive spirits lingered in the air. That is when A came rushing to my room,"Sir, my little sister B[20F] just called,she has decided to join the same college as us and has decided to visit once before starting next year.She is going to stay here for 2 weeks". It was decided to not let her know about the recent changes between her brother and his best friend. All our sexual activities would be limited and secretive to keep her oblivious from the the recent changes. She arrived and greeted us warmly. We show her the guest bedroom and tell her to relax as id it's her own house. During the 1st week of her stay she had noticed that I was ordering A around pretty much for everything and the shocking fact for her was,he was complying. B had never seen A in such a vulnerable,saying'yes' to everything state. But she didn't mind much.One night ,she woke up to go to the bathroom and on her way there she passed my room and to her dismay, she heard someone crying and begging to someone.Upon listening closely she identified the voice was of none other than her own brother."Please sir, my ass is burning,isn't 25 whips enough for today! I promise you I will never repeat the same mistake again "This had gotten her heart racing. Why was his brother pleading someone to stop whipping his ass.And why was it coming from J's room. She had never witnessed his brother crying in her 20 years of life,but she also couldn't help picturing her brother's red ass from being whipped. She always had a little crush on me,but had never thought about it as anything more. She felt some tingles. What was happening to her? Why is she thinking about all this stuff. She wandered back to bed with the intent of investigating more.

This is the storyline for the sister. It is upto the roleplayers to develop it further,and drive her into my submission.

The storyline of the parents will be introduced once the rolplayers for brother and sister have been decided.This is an elaborate roleplay and many other things will be introduced.Interested players don't forget to add sunflower to their message.Just a way to make sure, you read till the end.
