Accidental fun at the pool

I'm 52, mostly straight, but this happened to me one summer. I was on my way home from the bar, but not ready to turn in, so I bought some beer and decided to hang out at one of my apartment's pools. They close at 10, but it was still 9:30 and no one checks anyway, and when I got there, there was only a young black couple on lawn chairs. I cracked a beer and got in the water, which felt warm from the hot day. The couple nodded at me, they looked like they were in their let 30's, her in a bathing suit, him in a t-shirt and shorts. Once 10 o'clock hit, the pool lights turned off, and the couple picked up their stuff and left. I was quite drunk by then, and since I was alone, pulled my shorts off under water and put them on the side by my beer. The feeling of swimming naked was wonderful. Just then I heard a noise from the gate, and I froze. The man had returned, alone, and was walking back to his chair carrying a thermos. Now I was pretty sure he couldn't see under water, but to be safe I swam to the side. "forget something"? I asked, as he sat down, and he replied, "wasn't ready to sleep yet, and it's peaceful here" . I told him same for me, and how I was winding my day down also. "How is the water"?, he asked, and before I realized what I was saying, I told him "warm and wonderful". He removed his shoes and shirt, and walked to the pool steps and gingerly entered the water. Now me, I'm naked underneath the surface but sufficiently drunk, and strangely excited, and I felt my dick begin to swell. Taking deep breaths, I cracked another beer and offered him one. He pointed to his thermos and said "got my own", at which time he swam to it and took a drink. Suddenly I had a problem...I needed to pee. Obviously I couldn't get out without divulging my secret, so I decided to come clean..I explained apologetically that I thought I was alone, so I was skinny dipping, and he just laughed. I told him not to look, got out, and peed in the bushes, and quickly got back in the warm water, my hand covering my junk. He swam into the deep end and went under water for a few seconds...when he came up, he smiled at me, then held up something in his right hand....his shorts! "When in Rome", he said, tossing them by his drink. I laughed and drank my beer, but realized my hand was shaking and my heart was beating fast. The thought of his member loose swaying under the water was making me horny "af". I swam the length of the pool and back, making sure to veer towards him...to my surprise he was directly in my path "What's the password?" he asked, smiling. I quickly submerged, pretending to try to swim around him On my second stroke, my right hand touched his hip, and I quickly felt my way to his cock...it was already half hard and felt great in my hand. I came up for air, still holding onto his dick, right next to him. Before he could say anything, I told him "I just remembered the password" and went back under water and guided his cock to my mouth. It felt large and warm, and fantastic...I couldn't see anything, but I bobbed up and down on his large manhood until I had to come up for breath. He took my dick and guided me to the shallow end, where he stroked me gently, until I couldn't control it no more, and told him to stand up and watch for people. When he stood out of the water, I got a look at his cock for the first time,,, black and beautiful, cut, and about 8 inches and rock hard. I licked around the tip, and up and down the shaft, and then just took him into my mouth...I bobbed up and down, working my hand on the shaft, and soon he was tensing up and making strange noises softly...I suddenly felt his hot goo in my mouth and I took it out and let him cum all over my face...Panting, we both collapsed into the water...he hurried out after that, saying he needed to get home...when I got home, I noticed there was still some cum on my goatee, I always hoped to run into him again, but I never did..
