My first masturbation and orgasm came when I was 12. One night, I saw my parents go into the shower room together. My father was 40 and my mother was 36 at that time. Dad was rather fat but my mom had a nice body with big tits.
Through the small window on the top of the shower room, I used to peep at my mom having a shower many times. She had big tits, around 36D, with big pink nipples. Also, her pubic hair was very dark and soft. I used to masturbate after I had peeped at her.
That night, I saw my mom and dad make love in all sorts of different ways. My father sucked her nipples, my mother jacked my fathers cock. At last, my mother began to moan lightly. Both of their sounds were louder and louder. I was so excited that I stroked my erect penis, and I had my first organsm!
