I Can’t Believe I Did This.

I still do this when the opportunity rises.
When I was 13 I started to peep on my older sister. In the shower, through the window when I could and knew she was changing. Basically any time I could. Yes I got caught a few times. She never really seemed to mind to be honest and I don’t know why maybe she excepted her little brother to be a perv.
I’d sniff her dirty panties while jerking off. Man the had a different smell when she spent time with her boyfriend and yes I was jealous and I am still jealous of her husband to this day.
I think she’d use my perveryness against me. Tell me to do things around the house that mom and dad told her to do and she didn’t want to.
She’d tease me and walk around the house in towel or revealing undies.
Yes I crushed on my sister hard.
I can’t even the only one?
Did any sisters crush on their brothers?
