I never thought it would feel so good.
When I was recently working at my landscaping job I had this experience. The day was very hot, so I had taken off my shirt while I finished cutting the lawn. I had never seen anyone at this house, like so many, the owner was not at home when we were working.
I happened to look up at the house as I went by and saw her in the window. She waved and smiled and pointed to the open screen door. I went over to see what she wanted.
What happened next I couldn't believe. She was standing just inside the door with a t-shirt on. It was short enough that I could see she had no panties on. Since I was wearing shorts it was easy for her to see I was now getting a major hard-on. She opened the door and took me by the hand.
It turns out she was back from college and had watched for a couple weeks, masturbating by the window as I went by. This time she wanted my help. Pulling the shirt over her head I saw the most perfect breasts I had ever seen. Her nipples were sticking straight out. WOW! She pinched her right nipple and ran her other hand down between her legs.
She asked me to drop my shorts and join her. I didn't hesitate. I was fully erect now and eight inches was now standing straight out. She let out a little moan as she saw my pulsing member now grasped in my hand. We kept our eyes on each other as we worked ourselves to orgasm.
She came first falling to her knees as she came. This caused me to cum more powerfully than ever before, with the first jet landing on her left breast. She reached over and grabbed me, finishing the last spurts directly onto her chest. I could not believe how hard I came. We cleaned up and chatted for a while. I had to finish the lawn now, but she told me to look the next time I was there and she would be waiting.
