It had been a long day and I was horny as hell, I just didn't feel like jacking off by myself once again, I needed some company so I decided to head to the park toilets and test my luck at finding someone. When I entered, there was already one cubicle already in use, I went into the cubicle next to it and straight away I could hear two men talking about sex, then hearing wet sloppy slurps and wet kisses, when I heard the soft moans of pleasure I knew they were having sex.
At first I was jealous as I was there for the same reason to find someone to have fun with, I sat on the toilet listening to them enjoying what I had wanted, Hearing the cubicle door unlock I looked thru the crack in the door, It happened so quick that I thought I had imagined what I had just seen, my 21yr old son was coming out of a toilet cubicle followed by an older guy. The older guy was thanking him for what a great job he had done.
As soon as I saw my son had left, I stepped out of the cubicle and stood next to the old guy washing his hands, as I began washing my hands the old guy gave me a smile knowing that I had heard them in the cubicle.
"You just missed one of the best cock suckers I have ever been sucked by." He told me, then added he was a horny young guy too.
"Is he a regular here?" I asked.
"He told me it was his second time, and he is having trouble with his wife." I was told.
The old guy walked out of the toilet and I followed a minute later, my mind filled with questions and no answers, why was my son having trouble with his new wife, how long has he been bi. What could I do to help him; how do I tell him I heard him sucking a old man in the next cubicle.
It had been years since I had seen him nude, now I started thinking of what he might look like now he was older. I decided to send him a message to pop in for a chat when was free and then thought of ways I could bring up the subject of problems at home and about his new found sexual activities.
When I got home, I had the house to myself, my wife had gone away for a weekend with her friends once again. I hopped into the shower and then dried off no one was around so I could stay naked, I put on the porn dvd and sat down watching it on tv it was one of my favourites where two bi guys share a female, I immediately thought how good a threesome with my son and his wife would be.
My cock was throbbing and twitching as I gently stroke it slowly I was in no rush to cum so quick again as I laid back on the couch with my legs apart. The tv wasn't turned up very loud and when I heard a noise from behind me I shot straight up and looked over my shoulder to see my son standing there watching me.
"How long you been there watching, you didn't message me you were coming over?" I said to him.
"Not very long." He told me as he kept staring at my cock.
"What are you doing here anyway?" I asked him.
