I do believe gym locker rooms are the best place to meet guys looking for gay sex. Being naked with other guys opens possibilities and I have been lucky a few times. One of my earliest memories was observing a guy dry himself as I was getting dressed. He was in mid 50, well built, about 5'10", 180. I noticed his cock was not just nice, but kind of semi hard as he used the towel to dry himself up. We were alone that late morning, and he noticed that I was looking and decided to give me a show and a better view. By then I was openly admiring his cock and we caught each others eye and smiled.
"Looking good," I said to him. He laughed and said, "Not much use as my wife does not use it enough. She is always working or too tired after work."
"Well, there are always other options," I replied smiling as I walked closer to him and sat down next to him, with my face eye level with his cock. He dropped his towel and I could see his cock in all its glory. Definitely not the biggest I had seen, but definitely a good 6.5" and nicely proportioned. "Your wife's loss," I said smiling. "Is she home now?" I asked.
"No, she works 12 hour shifts, so will not be back till 8pm," he responded. "I have the house to myself, if you want to come over."
I did not need a further invitation and after he got dressed, I followed him to his house a few miles away. Parking in his driveway, I followed him to his nice single family home in a quiet neighborhood. Opening the door, we walked in and, as he placed his gym back on the couch, I closed the door and immediately dropped to my knees.
He had his gym sweat pants on, and I knew that he did not have any underwear on. I could see the outline of his cock over his sweat pants and I nuzzled the outline against my face. I placed my hands on his ass and pulled him against me feeling his cock grow. We were in his living room, both fully dressed and me on my knees. Reaching behind, I pushed his sweat pants down to his knees and the cock was inches away from my mouth. I leaned in and kissed the head, running my tongue gently over the slit. He grabbed my head and pulled it on his cock and he thrust it hard into my mouth. It slid in easily and I started sucking on it.
