And I was surrounded by many nude people the second I walked in to the swimming area. This club is for adults only and sex is allowed in certain areas including the swimming area. I walked in and found a chair and put my bag down and laid my towel out. I took my shirt off and started to take my shorts off. That's when I noticed that one of the women there was watching me. She was a bit older than me, I am on my early 30's and she was probably in her mid 40's. She was relatively attractive. Not a model by any means, but in decent shape with tan skin and long brown hair. She was sitting down diagonally around the corner of the pool from me and was about 10 ft away. Knowing that she was looking at me was such a turn on and I could feel my penis start to become erect. I slid my shorts off which revealed my growing bulge in my favorite blue briefs. I looked to see if she was still watching me and she was. I was so turned on that when I slid my briefs off my cock bounced to attention. She was still watching and my excitement didn't stop. I sat down and slid down in my chair so my throbbing erection was standing straight up. When I do this I saw her hand slide between her legs. I could barely believe it. I turned my chair slightly so we were looking right at each other and took the shaft of my hard dick into my hand. She spread her legs slightly and I could see her rubbing her finger in between her lips and over her clit. I stroked up and down the length of my erection slowly and she stared intently at my engorged member. She rubbed her lips and clit a little faster and then slid a finger inside her vagina. I could feel the head of penis pulse and get bigger. I stroked faster as well. She continued to stare and I continues to stroke. I was so turned on that she was watching me jack off that it didn't take long before I was ready to blow. I stroked faster as she watched and the gripped that shaft of my dick and cum cam spurting out of my tip. She watched every shot and robbed her clit vigorously. I didn't try to hide my cum soaked erection when I stood up and headed to the public shower. I rinsed off and when I turned back to my chair I found she wasn't there. I don't know of she came or not, but I had an intense time anyway.
