While growing up I have always googled by younger sister who had big boobs and bulging bottoms. I learned about sexual intercourse from my friends. While bathing in the nearby river my friend who is just 12 years old showed his erect penis and asked me to show how long my penis would grow. I too displayed my erect penis and we had mutual jerking.
While masturbating I would always think of my younger sister who grew from a small girl to big booby girl. I have always dream of having sex with her. One day during her afternoon sleep I chanced upon her skirt slightly falling away from the edge of the bed due to the wind of the fan.
Being too horny I slowly tip toed near and slowly lifted the half skirt aside over her back. To my surprise she was not wearing panties and the white buttocks protruding and as her legs were slightly upwards, her vagina lips and labia were clearly visible as there were only less pubic hair at the downside. Her anus too was very beautiful.
But I had no courage to touch her as she was 18 years of age and myself 20 years of age at that time. Just googled enough and went to my room and jerked off with a lot of cum.
