Chapter 20 Sex With My Younger Brother

I am the middle among my family, one older stepbrother and one younger sister. I did not feel sleepy, it was getting late, but I heard some noises coming out of my mom and dad’s room. I tried to listen, it was more of moans and very low sounds. I opened my bedroom door; it was dark outside in the hall. I was in my bra and panties only, so I put on a long shirt and walked out on the tips of my toes trying to figure out what was going on.
