This is the weird, but nice way I discovered how to masturbate:
My sister just came out and said to me one night, 'Do you want to feel something wonderful?'. I was 12 and curious so I said yes, expecting to be passed a soft toy or something with a nice feel. I was stunned when she came over, slipped into my bed, reached down and started to fondle my clitoris. She told me to trust her and just to concentrate on the sensations I was getting. It was shocking but lovely and yes I orgasmed at her hand. I returned the favor and we got into the habit of having mutual masturbation sessions at least a couple of times a week from then on.
We hardly ever did ourselves while we shared a room, preferring just to ask each other to do us when we needed easing. It all ended when she went to college but we have done each other a couple of times since in the past few years. The most notable was on her wedding day last August when she asked me to be her dresser and when we were alone she asked me to masturbate her.
