When I was in seventh grade I came home from school one afternoon and heard a strange sound coming from my older sister's room. I quietly crept down the hallway to her open door and was astounded watching her laying completely naked on her bed fingering her pussy. Her breathing was intense as she put her entire focus on strumming what I shortly would learn was her clitoris. I hungrily watched the first orgasm of my young life. While I stood in awe of what I had just witnessed my sister noticed me standing in the doorway and invited me in. That afternoon she taught me about how to masturbate, calling it "Jilling-off". As you will see, I still enjoy doing it to this very day!
