Well the first time I went down on someone, I was 13 and she was too. She was my neighbor, and she had a tent in her back yard, and we would spend hours in there. I remember I was wearing a tight bathing suit, and I was really skinny at that age, and my cock was pretty much the size it is now, and it would get hard so very easily. We would sometimes experiment with kissing, and this time since I was wearing the skimpy bathing suit my bulge really started showing. She noticed it of course, and said she wanted to see it. So I pulled my bathing suit aside and let her see. I remember at some point taking them off completely, and she just stared at it with eyes wide. I then asked if I could see her privates, she protested at first then after me begging for a while, she pulled her bathing suit aside, and I saw the most perfect little pussy I ever did see. It was hairless, and just so inviting that I just buried my face into, she was at first surprised, but soon she was moaning with pleasure. I gave her, her first orgasm.
We did this from time to time, although she never went down on me, and we never did fuck. A year later she invited me over when her friend was staying over, and me and her friend fooled around in her bed while she was on the floor with her boyfriend fooling around. Her friend had really big tits, and she went down on me, and it wasn't so good. She was using her teeth or something and it hurt. At the time I thought this was suppose to be how it felt, and I didn't want to hurt her feelings so I didn't say anything. Turned me off to BJ's for a while, until I met someone who knew what they were doing.
