I just went to have my yearly physical. My doctor said I needed to start exercising to shed the ten pounds I have gained from the previous year.. I decided to go out to the state park not far from where I live. I took a drive out there one day. When I pulled into the parking lot there were only two other cars there. I smiled and figured I had the place mostly to myself. I walked down one of the paths for maybe ten minutes. The trail came to a fork. One went to the right and the other went up a hill. I took the path upwards in order to give my heart a workout.
I huffed and puffed until I got to the top. I had to rest a minute to catch my breath. I started to walk down to an open area where there were some tall trees maybe one hundred feet tall. I suddenly thought I heard voices. Damn, I was hoping I wouldn't run into anyone here. I walked closer and then I saw them. It was two naked men and they were fucking. I stood and watched them for some time. I hated to admit it, but I was getting excited.
My cock was swelling up in my pants. I considered myself straight, but I had begun to wonder what it would be like to be with another man lately. There was a tree that had fallen down and one guy was bent over it. The other guy was standing behind him thrusting his cock into his ass. I stepped closer to see them, but I must have stepped on a dried branch. The guy doing the fucking turned around and saw me. He quickly pulled out and gathered up his clothes and went running off bare ass naked.
The guy being fucked turned around to look at me. He must have been in his early twenties. He was thin and his cock was dangling down between his legs.
"Are you the Park Ranger?" He asked me.
I told him I wasn't. He gave me a big smile.
"Do you want to fuck me?"
Damn, I was horny from watching them both. I had never done anything with another man before. I walked closer and the naked guy bent over the tree once more. I could see his pucker hole looking right at me. I surprised myself by starting to undress. I took off my shirt and then my pants and undies. I only had my shoes on. I turned around and made sure no one was watching. I walked closer and I took hold of my cock.
I rubbed my shaft up and down the crack of his ass. My new friend let out this moan. My dick was rock hard now. I slowly positioned my mushroom at his opening and started to push into him. My friend was so tight. I had to work some minutes before I had half my dick inside his bottom. I placed my hands on his hips and I started to stroke his ass. I have to admit I loved how it felt. I kept working into his hole until I was totally buried in his ass.
We got into it. I was pounding his tight rim and my lover was crying out as I thrust my dick in the whole way. I placed my chest on his back and gave him every inch of my cock. I am just an average six inches in length, but my cock is pretty thick. I guess I lost control of myself and started to fuck his ass as hard as was possible.
"God, your dick is big!" He shouted at me.
