Lucas was great at sports, even sports he had never before played. He excelled at them all and he was on most of the sports teams and this year he decided to come out for the swim team. I was the captain, not because I was the oldest, but because I had been doing it for four years. Our coach had asked me to get to the pool early with Lucas, just to set it up and get him started before the other kids came, because we had already been into the season for two weeks so he was a little behind. I went and got him out of class and we walked over to the pool. I gave him one of the team speedos I had brought along for him to try on.
I gave him one and told him to try it on while I went out on deck and started setting up. I went back in to find out what was taking him so long, he was standing in front of the mirror flexing in his new speedos, his biceps were huge and his quads were enormous and so heavily muscled that he looked like a body builder and his abs and pecs were very defined. Then there was his bulge, the bulge in his speedos were stretching the tight fabric to its limits. 'Woa' I said 'I think you need a bigger speedo your bulge is just about ready to bust out of that one.' 'Here' I said and tossed him the next bigger size. Then he started to get changed into my bathing suit too while I watched he undid the tie and slid them down and I couldn't help but stare at the size of his huge shaved cock and egg sized balls. He fondled himself for a bit before pulling on the next bathing suit but by the time he had pulled it on he was all ready semi-erect, the head of his huge cock was poking out the top of his speedo. I laughed 'good luck trying to get that dick of yours in there, now you had enough trouble getting your horse cock in there before' He sat down on the bench and as it began to grow to it full size he began to stroke it.
His cock was at least nine or ten inches long and his huge balls bounced up and down as he stroked it. 'Want to join' he asked 'Sure, I guess it's better than just waiting around I suppose' So I sat down and whipped out my dick, my dick was not nearly as big as his but the two inches it lacked in length was made up in the thickness of my dick. 'You aren't too small yourself there' he reached over, his hand grabbed the bottom of my shaft 'Damn that's a fat cock' he said. I moved my hand and watched him try to grasp my fat cock, then he started to stroke it. I lay back enjoying it. Then I lay my hand on his giant muscular quads and moved up towards his huge shaft and balls. I started to fondle his egg sized balls with one hand while he jerked both our cocks. Then I moved from his balls to his long hard shaft and started to jerk it. After ten minutes or so he cummed the biggest load I have ever seen, it was everywhere, giant ropes of it landed on his ripped chest and abs and all over the floor. After seeing this I couldn't help but cum, ropes of it shot all over his huge muscular legs. After a quick clean up we packed our now semi erect cocks back into our speedos and finally headed out on to deck for our swim practice.
