Hot tub encounter

I live alone now and enjoying the solitude for now. It was late at night and a cool night so I decided to take a soak in my hot tub. I don’t have a privacy fence but I am backed up to a conservation area and just had older ladies living on either side. They went to bed early and had turned off their lights.
I didn’t want to soak in my swim trunks so I slid them off and entered the hot tub. The only light was a glowing light that was powered by solar panel mounted on top like you line your walkway to the entrance but I had put one near the hot tub. I knew that no one could see me naked as I slipped into the hot water and settled down and started to stroke my semi erect cock.
I soon heard a knock on my screen door to the pool cage. I looked around and saw my neighbor standing at my door a few feet from the tub. Her name is Beth, short for Elizabeth. She asked if she could join me as she opened the screen door and entered wearing a robe and carrying a towel. I studdered a few times and said ok, but please turn around and hand me my bathing suit. She looked at me and I was sure she could see my cock that I had worked up to full erection. She smiled, no need I prefer to soak naked as she shed her robe and pulled her bathing suit off and tossed it aside.
She was an older woman in her late sixties or so but her body was well kept and she had small breasts with little sag and nice large nipples. As she started to grab the rail she was a little shakey so I stood up and moved to the steps and grabbed her hands as she went down the steps and ended in my arms and her body was totally against mine and I could feel her nipples poking my chest.
