A long time again my moms best friend moved in next door. I was 18 at the time and she was about 38, she was attractive but always wore baggy or lose fitting clothing that hid her body.
One day I was outside in my back yard when I heard a splash next door. A few minutes later I walked over and looked through a gap in the fence, it was my moms fiend, she was swimming in their pool, as I watched she swam over to the edge and got out.
I was shocked to see she was completely nude, the water dripped down her as she walked to a pool chair, I was surprised to see what a killer body she had been hiding under all her baggy clothing.
I started feeling aroused and could feel an erection coming on, she then lay down on the chair.
A minute later her hand began to wonder, until it found her groin. She began to stroke her vagina, at first just rubbing, then she slipped a finger in.
