I understand the craving. Hadn't been active after I left home for college, about ten years. Then suddenly our neighbor's boyfriend brought her a pit bull and chained it in the yard, he was huge and friendly. I heard him whining in the middle of the night because he was twisted on his chain and couldn't move, the neighbors must have been gone, no cars or lights on. I opened their gate and unraveled the poor guy. He was so happy. I played with him a little and noticed he got rock-hard and had a huge knot still in his sheath. I don't know what came over me but I reached down and took it in my hand while a few inches of his cock stuck out. No kidding, my mouth actually watered as soon as I touched that huge, red cock. He seemed to enjoy it, I was worried about getting bit. But suddenly my face was down at his belly and I had the tip of his cock in my mouth. I licked the tip and he started to squirt precum on my tongue. I stopped after just a few seconds and went inside and finished myself off. I was living with a girl at the time so I didn't want to risk getting caught. I didn't play with him ever again but I was shocked at how much desire filled me so quickly and how I had no control over my actions. It was like "I'm sucking this cock, it's time to suck this cock, now I'm sucking this cock." Especially since I hadn't even thought about it for years at that point.
