I was around 12 or 13 years old when this happened. It involved the boy who lived in the house behind ours who was around 15 years old. As I grew up he and I and other kids often played with each others. Then there was this time he and I were alone talking to each other in his back yard and it was then that he asked me if I'd like to see his cum. I had no idea what he was talking about and told him I didn't. He went on telling me it was his sperm. I had heard of this and had seen sperm on TV numerous times showing these little cells with there long tails swimming aroung. I also knew enough about sperm cells fertilizing eggs making new life. So I was certainly interested in seeing this.
I then told him if cum was sperm I'd like to see it. Was I ever in for a shock! He opened his zipper on his pants and pulled out his penis and it was enormous! I'd heard of boys getting hard and about having sex but it was still a shock seeing just how big and hard it was. He then wrapped his hand around it and went to stroking it. It wasn't long and shut his eyes real tight letting out a deep grunting sound. He grabbed my hand holding it in front of his penis and it happened. Shot after shot of this thick white stuff shot out of his penis into my hand. He then straightened out telling me that was his sperm and also called cum. I felt it telling him how gross it was and wiped my hand on the grass.
Little did I know then how much I'd grow to love this stuff and enjoy getting it. I'm now 19-years-old and have gotten lots of this stuff called cum from lots of boys. Of course they also return the favor giving me fantastic orgasms with there fingers. They've all wanted to put there cum inside me but I've so far always said no wanting to reserve this for my husband. I'm always tempted but so far so good. I don't know what we would had done if we couldn't 'play' with each other. It sure does feel good to do this.
