I was 14 when this took place my friend was 13 and I studied his penis.
I remember a time when I had stared at a friends penis for 10 minutes. I was spending the night at a friend's house and really couldn't sleep that night and I had woke up around two am and decided to watch TV until I was sleepy.
The light from the television was enough for me to see that while my friend was sleep he had kicked his sheets off. Also his boxer shorts were not hiding any of his private area, because the leg seemed to be stretched out and was twisted in a way that allowed me to see everything.
Immediately my penis became erect and I turned the sound off on the TV and turned on the light in the room. In the day, when my friend was awake this would never ever happen because he is one of those macho types.
I was so nervous that even though the thought came across my mind I did not touch him, I just stared. I was touching myself however.
My friend is mexican so he has this nice brown skin and the skin of his penis and testicles was slightly darker. He had hair covering half of his pubic mound that was dark black and fairly straight, it looked soft rather than coarse. His penis was probably about four inches long and very veiny, even though he wasn't erect. His penis was thick around the base and his foreskin covered his entire head, and his testicles were almost hairless except for one single long hair on one. They were both extra wrinkly. His 'area' smelled like Ivory soap because he always showered before bed. I cannot smell that today without thinking of that night.
I studied his penis while I slowly stroked and eventually cummed on the side of his bed. I felt guilty for staring at my friend after I had cummed, but still took some time to photograph his penis in my mind.
Just a recap.
Entire private region slightly darker than the rest of his body except pubic mound which was lighter.
Pubic hair dark black and appeared soft, covered half of his pubic mound.
Penis was approximately four inches long, uncircumcised with long foreskin, muscular looking because of the veins especially around the base, and his penis was thicker than mine was and I would guess he was a little bigger girth wise than he was in length, even though I could be wrong but it definitely was not skinny.
Testicles very wrinkly with one single hair between the both of them that was long and curled around.
