When i was 14 I sat next to my sister and told here to wank me off.
She looked down and saw me hard and said she doesnt know what to do.
I told her I would teach her every day, and did.
Every afternoon when no one was home I went to her room.
A few weeks later i asked her to dress up for me in her tight black leotard and tights, she did and I stood her in front of me and felt her ALL over. She moaned, then I told her to wank it fast. By this time she was very good with her hands.
One day i sat her on a chair and told her to watch me and I wanked all over her. She was covered in cum then I stood her up and turned her around and put my cock between her legs and started moving so her legs would wank me. she just stood there letting me do it till she watched me cum.
