Measuring Cocks While Swimming

In the summer I was going up to visit my moms friend and so it wasn't as boring I was able to bring a friend I called as many as I could and eventually my friend B said yes and after driving a while we got there and after eating and whatever we went to the public beach. and after a bit of swimming it was a semi shallow lake I guess since we had to go out quite far to get deep and I'm not sure who started it but one of use pulled down their shorts since no one could see and the other followed suit. Naturally as teenagers probably 15 or 16 at the time it didn't take long for us to get rock hard being outside and with people swimming there too and my family on the shore even know they were quite far away, after a bit of swimming and stroking we talked about masturbation and how he had just started recently and was at my house while we were playing video games and he was on bottom bunk I thought that was kind of weird since he was few years behind. he had it pretty rough he said his sister was always trying to catch him naked and he didn't have a lock so he just jerked off by rubbing through his pants or whatever he was wearing while I liked to just full on stroke it in the open. After a bit of that he asked how big I was since the water was hard to see in less we were close to each other so we both took a piece of seaweed to measure ourselves then compared them I have not seen many dicks hard(6 or so) but his is by far the smallest I think it was probably 3 and a half while mine was almost 7 at the time I remember my piece being pretty much double his, he maybe would not of believed me but when we were that close measuring we could see each others dicks we didn't measure thickness but he seem to b quite thin too with a little head and circumcised. Then after a little more swimming and stroking I got closer to him while swimming and talking and he said not to get to close cause he didn't want us to see each other hard or something I guess he got a little more self conscience after measuring. A bit later my mom called us in to go home and after we took our time letting our cocks rest since we didn't cum or least I didn't I figured the constant arm movements would of given it away even with the water hiding it, so on the ride home with me and my fried in the 3rd row of the van we started playing with our cocks through our pants for most of the drive home this did little more then just tease me till I got home but maybe he was able to cum since that's how he said he did it most the time anyways. that was the only time we jerked off together I never really wanted to after that since he said he didn't want to see another dick or whatever and that was basically the point of not doing it by yourself, and I already had a friend who I was jerking off with thought if we did jerk off again I bet it would of been fun being so much longer and thicker then him wouldn't hurt the ego and I'm sure he could of had some fun jerking each other too.
