This was 6 years ago. This was how I and my girlfriend learned about cock. Very much hands on or should I say; 'eyes on'.
I and my girlfriend Kay were together all the time back when we were in our teens. This one evening she and I were looking for something in my closet and ended up on a stool standing on it to see the upper shelve. While up there, Kay turned and looked out my window. Our neighbor's house was very close to ours and there was a window on it that had this half curtain blocking the lower half of the window. Being on the stool, Kay could see over the top half and into the room there. She told me about it and that she could see the lower end of a bed. I joked with her telling her 'That's interesting'.
Later that evening, I climbed up the stool and looked over to see what Kay was talking about. Sure enough, there it was. Someone's bed. Then, all of a sudden, someone walked into the room and sat down on the bed. From where I and the window was, I could only see the lower half of the body. It was obvious that it was the boy that lived next door. He was a 18 or 19 year old boy that had finished school and was working. He sat on the bed a few minutes and then I saw him start messing around with his groin area. It didn't take me long to realize that he was playing around with his penis. What I called a dick back then. Then he laid an open magazine on the bed and I could make out it was a picture of a naked women he was looking at. I told Kay what I was seeing and she wanted up so she could see it too. I jumped down and Kay got up.
It was then that things really got good. Kay said 'He's taking off his pants'! She was all excited. Next, he laid down on the bed and there it was. His dick was in plain view. Kay like to have fallen off the stool! She said 'Oh my gosh; it's so big'! I yelled 'I want to see it now'. Kay jumped down and I climbed up. I looked and he was now stroking himself. I told kay 'He's jerking off now'. Kay wanted to see so we switched again. Kay watched a minute or so and jumped down. I climbed up and looked. I saw him thrusting his hips some and then saw this white stuff shooting out. I told Kay 'I think I just saw it. His sperm. His dick squirted something out'. I jumped down and Kay got on and looked. I told her 'It went all over him a while ago'.
Well, Kay missed that one, but on another evening she got to see him shoot. It was sure a sneeky way to learn but we sure did from this thing we came up with looking in that closet. Has come in handy too!
