Incest. It's not exactly a secret but it's one of those things you never talk about again after being told.
Edit: I actually meant incestual rape.
I was

when I found out our family secret. Back in the day, pretty much everybody's granddaddy did some foul shyt and their wives stayed with them because they had too. My grandmom was no different.
First, my granddaddy had 7 kids before meeting my grandma. My grandma also 7 kids with her first husband, then he died, so she married my granddaddy & they had 4 more kids together. So its 18 kids in total. Well, my granddaddy also had a young tender upstate he never told anybody about

She had a daughter by him but, the little girl died when she was a baby, so nobody ever found out until years after my grandpa died when one of his senile ass brothers admitted to it.
Second, and here is the disgusting one. My grandmama had 7 kids from her first husband like i said, so some of her children were grown or near being grown when she was deep into her marriage with my granddaddy. My granddaddy started fooling around with one of my grandmom's daughters from the first marriage. He got her pregnant twice. Twice nikka

That means he did that nasty shyt the first time, then turned around and did it again

My older "cousins" I'd known all my life were really my aunt and uncle. To this day, nobody talks about it. Their father is just some imaginary phantom nikka we never met that never existed

My aunt is a doctor now, real bourgeoise, nose in the air, stuck up sorority type broad, making 200k a year with a big ass house in the suburbs.....i guess she wanted to do as much as she could to push herself away from the fact that her mother fukked her step-daddy/mother's husband.
