I too had sex chat with both my Mommy and Sister. My Mommy Savitri is a High School teacher and she is well maintained like a really hot MILF and my Sister is a college student. During the lockdown I created some 5-6 fake IDs on Instagram and Facebook to kill the boring time and one day while browsing I saw my sister's profile in suggestion, so I sent a request and then we started to chat (I started it as a prank but it got naughty stuff involved) then I tried the same with my Mommy and I was surprised that I was able to have naughty discussion with both of them. About ongoing stuff, involvement of pornography, types of porn, their figure and what clothes they were wearing to flirting and then finally sex chat. I used to send them Porn GIFs while having sex chat. And many I must say that those conversations were wild, I couldn't believe that I was discussing anal sex and group sex and incest with my own mother and sister. I made my Mommy imagine her son friends fucking her while her son watching her and she cummed at the end of the chat. I made my sister imagine threesome with her classmates and her brother peeping while she was masturbating and made her cum at the end of the chat. But as every good things end so did our chat ended when I asked them to share her nudes multiple times, they blocked me. But they did shared some nudes during the chat which they downloaded from the internet.
