This story happened right after my graduation party from college at my parent's house.
My friends Josh and Kam hung around after the party ended and we sat in our hot tub talking about old times and where we were heading next. I told Kam he should be a porn star with his huge dick that he had. Josh and I were always amazed when we saw Kam nude with his huge dick that swung between his legs as he walked.
I was really hot from sitting in the water so long so I joined Kam on the ledge of the tub and asked him point blank how big his cock got when it was hard. Josh said it probably didn't get any bigger than what it was now and that me and him probably had bigger dicks. Kam said no way guys and started to pull on his long circumsized cock. Josh popped out of the water and sat next to me so he could watch Kam's dick grow as it was already half hard and still getting longer. My dick was growing at the same time watching all of this and when I looked over at Josh he was stroking his dick to an erection. Kam had an excellent looking body and kept himself in shape like the rest of us but we couldn't believe the size of his cock now fully erect. Kam was stroking all 9 1/2' of his thick hard meat and we were right there with him. Josh's hard cock looked about 6' long and really thick with a big head and my cock was 7' and a thinner. You could hear us all moaning and as we watched each other beat off. I told Kam I was truly impressed with his huge cock and he asked if I wanted to stroke on it for awhile. I slid over on the top of the tub and took his big hard dick in my hand and slowly started stroking his long shaft. Precome was oozing out the tip of his head and I took it and rubbed it around the head and stroked faster. This was great, I thought Josh might freak out 'til I felt his hand on my hard cock. We all three moved together so we could beat each off and the sounds of us getting closer to orgasm was getting louder. Kam was now beating off Josh and Kam said he was ready to blast off in my hand as I just concentrated on the head of the huge dick. Suddenly, I started feeling like I knew I was ready to come and we all beat faster and faster 'til first Josh blasted his load all over his chest, then I came next covering Josh's hand with my load, and then I felt Kam's big cock grow even more in more hand as he let flew 5-6 huge jets of come all over his chest, stomach, and my hand. It was a great first time for all of us and we said we would have to do it again.
