I Learned About Sex When I Was 12 Years Old.

I lived with my mother, step dad and an older step brother. My biological father died when I was a baby. One night my mother came into my room and said she wanted to talk. She sat me down on my bed and asked what I knew about sex. I told her I didn't know anything. She asked if I knew what a penis was. I did its the thing boys pee from. She smiled as she pushed my step brother into my room. He was completely naked with a massive boner. I went to cover my eyes but my mother told me to look at him as she gave me a quick lesson on male anatomy. She then told me to remove my clothes. I was hesitant but I did it. She then gave my step brother a lesson on female anatomy. My mother then handed him a condom and walked us through the process of putting it on. She then gently pushed me onto the bed, and spread my legs apart. I don't know why but i didn't realize I was going to be fucked. My mother helped my step brother line himself up and gently pushed into me. She told me to relax and let him fuck me. After a bit I began enjoying it. of course I swear he came at the same time. My mother then told us to use a new condom everytime and handed us a box and told us to have fun. When I had my first orgasm he got so nervous that I was having a seziure. The next morning we told my mom we used the whole box and needed more. She came home with a giant surplus box. My step brother and I fucked eachother all the way through middle and high school. I had bfs and he had gfs but if one of us wanted to fuck we fucked no questions asked. Honestly we only stopped because we went to different colleges and both of us now have fiances.
