How I Learned
One summer morning when I woke up after sleeping in, like most teenagers do when they don't have school for the summer. I was heading towards the shower with only shorts on that I had slept in, when I noticed my parents door was open. Usually the door is closed at this time of day. I walk towards the door and looked through the crack of the door and to my amazement, I find my father pumping his cock I had never in my life seen my father naked, except when I was a child.
I stood there at the door for what seemed like an hour when it was only five minutes, then my dad looked straight at the door and seeing that I was watching him, so I ran towards the bathroom, closing the door and turning the shower on. When I get out of the shower and walk towards my room, I hear my dad yell out my name. I turned to go to his door, to find that he is still naked with a hard on. He said that he had seen me watching him and wanted to know if I wanted to join him as he had waited till I got out. I look at my dad for a moment and then said I guess so but I don't want it to be weird or anything.
I walk towards the bed and my dad stands up, taking the towel around my waste off and picks me up in his arms, with his huge cock stabbing me in between my legs. He holds me like this for some time, then throws me on the bed and returns laying down on the other end. I lay there trying to get my cock hard when I noticed how big he was. My dad is in his forties and he had to have had at least eight and a half inches. I turned, looked at mine and said that I wish mine was that big. My dad turns and tells me that by the time I turn 18, I will be that big. It gave me some encouragement.
My dad then says that we should go ahead and start, because he was starting to sweat due to how hot it was in the house. Dad reaches over, takes my cock in his hand and starts pumping my cock, so I returned the favour. Then we start jacking off each other. My dad takes his hand, spits in it to use as lube and starts pumping me again which felt so good. He could hear me groaning. So I take his cock once more in my hand and start jacking him off...
Then my dad starts to move his hips up and down through my hand as if he is fucking someone. He gets faster and faster when all of a sudden he blows this huge load all over my hand and arm. Dad lets out a huge moan, then I started doing what he did and its felt so good. Then I came all over his chest. Dad said that this was a once in a life time thing and that it was just something to try. Later to find out that we had more of these sessions.
