Mom caught me

I suspect more common than not, when I reached puberty she gave me a long talk about ** and how to not get a girl pregnant.
We had no ** ed in school back then, so my Mother stripped naked in front of me, and showed me all parts of ** and how to have ** without getting a girl pregnant.
She had me put my ** inside of her, then curl my ** upwards slightly and rub gently, I noticed her eyes started fluttering when I did that and she moaned.
Then she had me rub myself in front of her, next she used her own hands and showed me how to do it really slow to make the pleasure last.
Later on, my father did the same thing to my little sister, we were really close and I was her big brother so it was my job to protect her, so when she started dating she asked me how to handle grabby boys.
A couple of them got to deal with me later on.
But it was just the one time with my Mom, she never did anything like that again.

I will show you mine if you ** for me
