When I was around 18 I knew that I was GAY. I loved watching the guys change in the locker room in P.E. class; I also loved watching my step-dad shower in the mornings. We had one bathroom and we had to share it. Every morning I would make sure and be up before him and be in the bathroom doing something just to get a glimpse of him stroll in NAKED. He was hung nicely, as I remember almost, 10 inches. I was a nice size as well for my age, back then I was 8 inches; now I am 10 inches. Anyway, one morning I was boned up in the shower, washing up and my step-dad walks in. Today he was running later than usual.
He through open the shower curtains and said, 'Move over son and make room for daddy.'
So I did just that. We were washing up moving from the front of the shower to the back passing each other each time. Our cocks would touch and they started to come to life... I mean at FULL MAST!!!
He said to me, 'Looks like you are full-grown now.'
Then I said, 'Not as much as you.'
He told me to go ahead and feel it. So I did, as he did the same to me. We jacked each other off feeling and pulling our balls. I was in heaven; he came in spurts one after another. I came right after him. He then leaned on my shoulder and whispered to me that it was great and we shall do it again. Well we have and now we go all out whenever we can.
