I was home from college for the summer. One morning I was hanging out in the back yard after mom went to work. It was a beautiful day I had just slipped on a pair of cut-offs. As I sat out there the lady next-door stuck her head over the fence and asked if I would change her patio light for her. I said sure and jumped the small fence between the two houses.
She had the ladder all set up and the light bulb ready. So I climbed the ladder and changed the bulb. While I was up the ladder it was obvious that she was looking up my pant leg. The legs of my cut-offs were very short and just barely had me covered, so she got a really good look.
When I got down from the ladder I noticed that she was wearing a tank top and her nipples had hardened making a very distinctive impressions in her shirt. She thanked me for changing the light bulb and thanked me for the show. Somewhat embarrassed I told her she was welcome. She was a long time friend of moms and had watched me grow up. She had seen me nude more times than I can count as a little boy sometimes with a hardon and several times playing with my self. After that she mentioned that I appear to have grown a lot since the last time she had seen me nude. Then she asked if I would drop my pants so she could get a good look. I agreed and droped my pants.
Standing there she examined my limp dick and started asking questions about masturbating and how much cum I produced. As she talked my dick slowly hardened. Then she asked me to masturbate. I started stroking my cock slowly and she raised her top so she could play with her nipples. The more excited I got the faster I stroked. When I was ready to cum she opened her mouth so I could deposit my load.
I masturbated for her several more times that summer.
