We had just finished athletics training and there was 2 of us left in the change room. Mark then pulled his shorts off and was bare chested and had a nice looking package in his briefs. He then walked past me and without any notice pulled my breifs down to reveal my cock. He then told me to join him in the shower. I went in and he was holding his 8-incher and mine went straight to its full 7.5 inches.
He then jerked himself off all over me with his 8 ropes of long warm cum. He wiped up the cum and used it as lube to jerk me off. We washed up and we always try to do this when ever we can.
