I Have No Idea What Possessed Me To Do This

My parents divorced when I was around ten, lived with my dad and my mom moved a few states away from us so only went to her house on long holiday breaks and four weeks in the summers. My dad rarely went out, he would sometimes drink on the weekends but was never violent or anything like that, pretty much a happy drunk so to speak. One evening while he had already consumed quite a bit he asked me if I had a girlfriend and sort of poked me some, told him no was not really trying figuring girls were not that interested in me. We laughed and joked around some more then it was bed time, I was laying in my bed and could already hear him snoring away as usual. He was a heavy sleeper and hard to wake up even when sober in the mornings during the week, I had this crazy idea of wanting to see his penis and slowly went into his room and got up on the bed. I slowly worked the covers down off of him, nothing but snoring out of him the whole time and suddenly I saw the head of it because he went to sleep naked. I stared at it for several minutes, again no idea why I was so fascinated with it, I had my own but his seemed so incredible with all his hair and of course it was larger than mine. I had seen him a few times when I was younger when we showered together, nothing happened back then, totally normal. So I am building up the courage to touch him and finally run a few fingers up and down it, he slowly began getting an erection with a few snorts and breaks in the snoring but always returned to it. I slowly laid my head right down on his torso my face inches from the tip of his cock as I kept just running a finger or two over it and it kept getting harder and longer then finally was on my lips. I licked it a few times and could feel myself tingling all over from the excitement of it, I opened wide and began lightly sucking on the entire head then a little more at time until I had like two inches of it in my mouth. His torso contracted and he snorted awake, John! he exclaimed, What!, Huh, Oh my, what are you doing?!?! I never stopped sucking and he did not pull me away from it, I began feeling him moving so that it was going faster and further into my mouth then minutes later the ejaculations started and I just closed my lips around the head swallowing. I sat back up and looked at him, he had his hands on his face holding the sides of it, why did you do that he asked me, I did not know really, just wanted to do it I told him. I asked him what it felt like and had heard from others at school that it felt really good, he laughed at me saying believe me, none of your friends have had this done to them yet. He told me to go back to my bed and we would talk about it in the morning so I got off his bed and went back to my room. The next morning I woke up and went out to the kitchen, saw him sitting at the table drinking coffee and we had a brief exchange of good mornings and what was for breakfast. He then let out a sigh and asked me about last night, why did I do it, told him again I was not sure, just wanted to do it and I asked him if it felt good again, he told me it did but that was not the point. We had a pretty good conversation about it and somewhere in there I got the impression that it was okay, the following weekend he was having a particularly good night drinking his whiskey and we were laughing at some TV show then he said it was time for bed. I came into his room minutes after hearing the snoring wanting to repeat what I had done before but he woke up soon after the first few touches of his cock head, Son! he said somewhat in a sleepy voice and there was a long pause then I heard him say Oh what the hell, do what you want to it. I laid my head back down and began licking the head and running my fingers up and down the shaft, sucked harder this time on the head giving him an orgasm and then just laid there suckling on it for a few minutes listening to him moan and tell me that I needed to keep this between them and not tell a soul. I was laying in bed during the week one night, no drinking at all that evening which was not unusual for him during the weekdays, I wanted to suck on him though and was not sure how it would go just walking to his room and asking to do it. He laughed a bit and said Okay, if you really want to do it and from then on he never turned me down. When I was out at my moms house a few summers later and around fourteen then I had made friends with the boy about my age next door, he was over and we were in my room, no one else home and I asked him if he could keep a secret. He said yes but I still was nervous to ask him if he would let me suck on his cock, his face smiled big time when I finally got my nerve up, told me it was his first time ever getting one and I could do it anytime I wanted. When i returned back to my dads house I decided that I was done with it when school started that fall, he never asked me about it at all.
