I', lucky

Hi, I'm 15 and I'm going in class nine. We have sports twice a week. In the showers, we have three booths with protection against the sides, but on the other side there is no protection so you can se who is there. Today when we were showering after class I took the booth in the middle and two friends the other two. Then this guy that I like took the shower in front of me where there was no protection. I was not thinking of it first but then when I looked up and saw that he had a very big cock. I had never thought about it but it was really great ... it must have been 7 inches or larger. The booths have glass so that you can only look out and not in. So 'X' could not see that I saw him. I could jerk off without him noticing it and it was so nice xD
