A real thing that happened when I was back in High School...
One night I was invited to my friends for a sleep over. We were both 14 at the time and we had known each other for about a year. We were watching a movie and it was quite boring so I asked him if he ever masturbated, he replied yes. I also asked him if he has seen another boys penis before, he said no, which means we both hadn't.
I asked him a few minutes later if he ever wanted to and one thing led to another to the point where we both agreed to show each other when his parents go to sleep. We just continued watching the movie and playing video games until it got to around midnight.
His parents were asleep and we went to the lounge room to watch some tv. I asked him if he wanted too and he was really nervous at first but he said sure. I had to show him mine first, I was as hard as anything just thinking about it so I pulled it out and I had a 15cm boner, he said it was a lot bigger than his. I persuaded him to show me his and he finally did. It was about half the size of mine, uncut and very neat.
We then just continued watching tv thinking of what we just saw. He then asked if I wanted to masturbate with him. I was taken by surprise but I said sure. We both got them out and kind of slowly started, we were quite nervous but then I reached over and grabbed his cock. He was already close and I finished him off. Thick ropes of cum shot out and hit me in the chest. He then grabbed me and probably 10 seconds later finished me off.
We still do this quite a bit and that night we did it three more times. Thanks for reading
