The first time a girl saw me orgasm
We had family friends staying. I was a single child and so was their daughter Judith who was two years older than me at 15. She was quite a big girl with large breasts which made my eyes stick out on stalks when I saw her in a bikini that afternoon on the beach near out home.
That night our parents went out and left us to watch tv. I was anxious to tell her of my discovery, I had been looking in my father's drawer and found an envelope with photographs in it. Pictures of a naked man and woman having sex. Now this was the 60's and these things were not commonplace at the time. it was hugely exciting and something which made me very hard very quickly.
I was keen to show Judith as we were talking about sex and bodies and the usual things. Shaking I pulled the pictures from the brown envelope knowing we were alone in the house. She said she'd never seen anything like them and thought the man's cock was very massive. I said it wasn't that big, as mine was pretty big. It wasn't but it felt like it! The man in the pictures wasn't that big either.
After a while we talked about orgasms as one picture showed the man with cum on his belly and the woman's hand holding his cock. Judith asked me how fast it came out and how much came out. I said it varied in speed and intensity. After a lot of persuasion she got me to agree to show her. I said I would if she did, but she said she couldn't take her clothes off as she had her period. She did though agree to take her top and bra off and reveal those massive mammaries.
When she did my cock just went into overdrive and was as big as I'd ever seen it. I took my things off and let her see. She was amazed, she felt it, and pinged it back and forth amazed at how it sprang back and hit my tummy. She told me to 'do it'. I started rubbing with one hand and felt her breasts with the other, they were heavier than I was expecting. She wanted to rub my cock for a bit so I let her and it was incredible. But she told me to do it to the end.
I was very shy but the eroticism of the moment was too great and as I stared at her eyes focused on my actions and then squeezed her large breasts I felt the pressure building in my balls. I told her it was coming out and then gasped and groaned as it spurted onto my belly. She was impressed.
Another time on a visit to her house she had me show some of her friends, but that time I insisted one of them pulled their knickers down too. They wouldn't, but one of them went and fetched her younger sister who was told she could watch if she stripped. But that's another story.
