I’m a married man in my 60’s.
Many years ago when I was in my 30’s and drunk, I had been masturbating and looking at porn when our male spaniel walked into the room and lay down and started licking his own cock. I watched him fascinated as his cock got bigger.
Being quite drunk and curious I threw caution to the wind and got down on the floor by the dog and started to suck his cock. He didn’t seem to mind. I only did it for a few seconds but felt so horny doing it.
All week I lay in bed thinking about what I’d done and feeling so guilty but also noted that every time I thought about it I got hard.
A week later, fully sober I tried it again. This time I made him come. Interesting taste! I was ashamed of myself so never did it again.
But I still think about it occasionally and still get hard!
