Mom And Sister Nude

Straight to the point!
I was home from college, celebrating my 23 birthday and caught jerking off to my older sister's bra by my dad.

He asked me if I liked the family stuff, I did I told him.

He told me that lying on the living room floor and looking through the heating vent, you could see directly into the bathroom and he has seen my sister shower

I took his advice peeked. I saw everything!
My mom was on full display also!

If any interest, I can elaborate more.
