She has been posing with her legs spread for her little brother for the past ten minutes while they are in the house alone all day. He just noticed on how her pussy is growing pinker by the minute. She replied with embarrassment to his observation. "This IS FUCKING FUN but don't ever tell anyone we did this. Mom and Dad would punish us for sure . You wanna try something that girls like a lot ? I'll teach ya and tell you what to do ."

Thinking she's been fucked many times in one day

I would fuck her in a heartbeat!
