One weekend she was at our house and my Mom was grocery shopping and my aunt was in the shower.
Mom made dinner and we all sat and ate.
Aunt Susan pulled her legs back and her ass went in the air.
I laid on my stomach and leaned in and licked and sucked her lips.
She saw her parents fucking and she saw her mom strip and lay in the bed with her legs spread and her father stuck his dick in her mom and fucked her.
She said they do if they are desperate and she needed the eggs.
Also, don't worry - she doesn't bite.
The 29 year old saw his super large dick but did not say a word.
