Gym shower part 1

After a hard workout, a long warm shower always gets me to relax those sore muscles. I ventured down the middle walkway, with showers on either side. The first one on left was taken, curtain fully closed. There was another shower that was been used two showers down on the left. This guys shower was closed also. I choose one shower past this last guy, on the right instead. Turned on the water and let it run a bit to insure the water was warm bit on the hot side. I removed towel, stood there for a minute and step in. I turned around to close shower curtain to find the guy across had open his curtain and had been looking at my ass. He was jacking his hard cock and smiled as I stood there fully exposed frontal. I returned the smile and closed curtain, Now I had a choice, do I return by opening my curtain so we could see each other or not. I could feel myself excited with the possibility of having some gym fun. I heard someone walk by and the curtain of a further down shower closing. The water was so nice and I could feel it hitting my now semi hard cock. I return to the thought of seen guy jacking his cut hard cock. It wasn't anything amazingly big, I'd say average. He wasn't that fit, not the jock type, but average type with a bit of a belly. I hadn't notice much more as I was totally caught of guard him standing there jacking his tool. I turned my water off to soap up and wash my hair. I got shampoo and started on my hair and then suddenly realized some shampoo got in my eye. I slightly open my curtain to brush eye on towel that was hanging. Got shampoo out of eye area and I saw guy across was standing there full boner for me to see. We made eye contact this time and he didnt look away but got a huge smile. I could feel myself getting erect again as I had relaxed when I started to shampoo my hair. His right hand went to his cock, while his other hand now started playing with his right nipple. I turned back into my shower and turned on water but didn't close curtain, leaving it a bit open. I washed out the shampoo out my hair and back up to dry my face with my hands. I knew by doing this my ass would be visible thru the opened curtain. I turned around and could see across to the guy now jacking his cock hard his legs bent slightly and his back to the wall of shower. He had closed his curtain a bit to avoid been seen by another guy walking by or gym staff. I turned off water to soap up. This liquid soap was the type that would lather up nice, not anything with big bubbles but good amount of lather. I slowly worked across my chest and then across the belly getting to my pubic hair. I would move into guy's sight thru the open curtain...
