It may seem strange that at 50 you realize that you are bi.
Perhaps an explanation is required. At 50 years old, with kids all grown and after 30 years of marriage, my wife asked for a divorce, saying she wanted to be free to do some of the things she wanted to do when she was younger but couldn't because of marriage and kids. After my surprise passed, we divorced on friendly terms, and she moved out of the house.
Since I had the house to myself for the first time in an exceedingly long time, now I could be nude inside and in the back yard, something my ex-wife did not approve of. There is an eight-foot brick wall around the back yard, allowing a totally private yard and pool area.
A few months passed and a good friend who was employed at the same trucking company as I had his marriage end after many years. John needed a place to stay, so I offered. He moved in and we shared the expenses. I worked days, and he worked nights, six twelve hour shifts each week. During the week, we would pass each other in the dispatch office, at home we had the house to ourselves.
Each year, the smelter we haul copper concentrates to shuts down to do smelter-wide maintenance. This allows the drivers to have a three day weekend in July.
To beat the heat, I got up early to catch up on some overdue yard work. I finished my chores around noon, then went swimming. About an hour later, John came out with his morning coffee and took a seat on the pool steps.
"What are you going to do for three days?" John asked me.
"Didn't really plan on doing anything. I thought you were going over to your girl-friend's place."
"I would have, but Sue had to go back to Iowa to help her mom, who has to have some surgery done."
We talked awhile about our jobs, and then decided that we would go to the store pick up some steaks to grill outside, have a good dinner and maybe rent a movie or two.
After buying the food, we headed to a small movie rental store. After looking and not finding something we cared to watch, we wandered into their adult section and picked up two movies.
We fixed dinner and ate, then swam until it was dark. We headed inside to watch the movies. We were joking around, watching the first one, making remarks about the size of the girls' breasts and the size of the guys' cocks, laughing, and enjoying the movie.
"Put the next movie in while I fix us some drinks," John said.
"Go ahead and start the movie. I will be right back," he said as he walked down the hall. When he returned he had removed his shorts and was naked.
John said, "If am going to watch a fuck movie, I am going to be naked, so I can play with my dick."
I was a bit surprised, but not shocked. I had seen men and boys nude in showers in high school and in the barracks while in the service. The surprise was that I found myself aroused seeing him nude and stroking his cock laying on the couch ten feet away from me. I said what the hell went into the bedroom stripped, and came back out to watch the movie.
At one point, John went into the kitchen to fix a drink, and as he came back, his cock was hard. Seeing it gave me an instant hard cock. As we watched the movie, John told me that he and his girl friend had gone to an adult theater where couples could watch a movie and swap or play around with each other.
"Watching my girl friend suck this other guy's dick made me want to do it, but I knew she wouldn't go for that. Have you ever thought about it?" John asks me.
"I guess a lot of guys have wondered what it was like to do it." I said.
"Seeing you nude and stroking your cock, watching the movie has made my cock hard and all tingly."
"I know." he said. "Same for me seeing you hard."
"Before you moved, in after the wife moved out, I was being a home nudist, but started wearing shorts because I did not want to embarrass you, John."
"Hell, it would have been ok with me, so how's about from now on, naked at home is the rule?"
"Works for me." I said.
We watched the movie, making a few comments, and watching each other stroking our cocks.
After a bit of time, John said, "I really would like to suck your cock, would that really freak you out?"
"No, I am horny as hell."
I slid down the couch, and he got between my legs.
