I told her that Jesus did indeed love her, and that he still does. She was so sexy, young, beautiful, my thoughts were racing with lust and sinful ideas. Then she came up with an idea to teach me how to jerk off!!! I laid on my back and my horny sister pulled out my penis, grabbed it with both hands and started moving her hands up and down. That was my first time masturbating, ever and I liked it so much! I started playing with my cock and masturbate all around the house, in my room, then in the bathroom and my sister caught me a few times.
