Is it normal to get a boner in front of my sister?
I am 19 and my sister is 18. Yesterday she farted and stained her panties with poop. I got a huge boner in my loose underwear. She smiled. We are home alone for the week so it's ok for us to do some things that we don't do infront of our parents. We went to my room to play video games. She was wearing a bra and panties. I got another boner for her. I started to change my underwear. She stopped me. She told me she wanted to have sex. I got into bed naked she changed. She kept her panties on for the first few minutes. She told me to close my eyes. She sharted on my face. I got a boner and we did it. Is this normal.
