At the Pool

One day at the swimming pool I was changing when a mother and her young son came in and started to get changed right beside me. So as I started to get undressed I was facing the mother (aged about thirty and hot) as I slid off my boxers. She glanced at me and smiled. She then took her son to the pool leaving me alone in the changing room. I had a raging erection at this point and started to stroke it. I hadn't heard the door open when the mother came in and caught me masturbating. She said 'Can I help?' I said sure. So she placed her hand on my cock and started rubbing it. I thrust my fingers in and out of her wet pussy. We continued to do that for a few minutes. I was in heaven. She grabbed a towel and headed back to the pool. I now see her every once in a while at the pool and we have some extra fun in the stalls.
