M4F sis getting a little too comfortable

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

You can be meenakshy 24y elder sister unmarried ,single working in banglore.. you are a friendly sister and we are a normal family.. it's been a while since we have talked..

I am 19 and just got your birthday last week..and am having actress addictions and exploring porn lately.. I put these actress statuses and all for my friends to see..and hide every other people..

One day i forget to hide you and you saw it.. i see you in the viewers list and gets panicked .. but to my surprise you comment on my status with a funny reply.. matching my vibe.. that was unexpected.. i knew my sister was chill but i didn't know she was that chill.. we talk that night and you told me not to hide me anymore..

Start with something very mild.. Step by step each day you increase the hotness of what you put in status and what we share and we become very open .. not lust for eachother.. but match the vibes of even sharing porn comfortably towards the end.. I need the plot to be very slow and realistic chat type with the boundary pushing and building upon fun and friendly conversations... Not lust for each other...

I will Start by sending the status i will be putting .. (anything that the sister can take cool and comment on.. but still hot to be hidden from sis)
