One good thing about having both parents that work, is you have a few hours of privacy between when you get home from school, and when they get home. My brother and I made the most of such times. The first time we fucked, it was unexpected. I came home from school and went to my room to change and I thought I was alone, since he usually hung out with friends after school. I didn’t close the door to my room as I was undressing and apparently he’d come in behind me and saw me starting to undress on the way to his room and stood and watched, then came into my room.
I was shocked to see him standing in the doorway watching me and went to shut the door, but he walked in, with a clear hard on in his pants. He reached over and squeezed my bare breast then leaned in to kiss me. I didn’t stop him and we were soon fucking on my bed. I had to admit, I loved his cock and he knew how to use it. He made me cum so much better than my boyfriend ever had and this became an afternoon habit for us after school.
One time our parents were asleep and he came in my room to fuck. I felt it was risky, but I wanted his cock so badly. We fucked on the floor, since I didn’t want any chance of a bed squeaking waking up our parents. It was so hot knowing we were in the room in the dark fucking as silently as we could be as they slept down the hall with no clue. This went on for a few years, and was the best sex I’ve ever had. I never told anyone about it, since I knew most people would not understand, but it was really hot.
