First time gay sex

I was working as a kitchen helper in a family owned restaurant way back in the mid 70's. I was 18 at the time. I became friends with one of the cooks,I kinda knew he was gay to begin with but that didn't bother me at all. He was several years older than me, possibly in his early 30's.
I had an old truck and helped him move some things from time to time. One day he invited me over to his place. It was immaculate. He poured me a double shot of whiskey and I drank it. Then another. Soon I was very drunk. The room was swirling around and I got sick After I was done throwing up in the toilet he said I can lay down on his bed. I'm fully clothed and laying on my side, I feel him get on the bed behind me. For some reason I reached around and felt his hard cock, he was only wearing his briefs at this time. Next thing I know I'm naked on my back. He's on my top of me and reaches into his nightstand and gets some lube and smears it all over my now hard cock. He puts my cock in his pussy and rides me until I shoot a big load. Then he jacks off onto my chest. After I recover a bit I get dressed, he tells me not to tell anyone ( who am I going to tell?). I never got back together with him again but years later I wish I had. That was fun!
