Speedo Stories - Part 2

This is the second part of my story about when my mom and I went on vacation. It was the summer after 6th grade, two months after I turned 13. We stayed at a Holiday Inn near the beach. A month before, when school let out for summer, I had gotten my first pair of speedos.  A boy in my class had worn them for swimming in P.E., and I wanted a pair from the first time I saw them.  I imagined how the tight silky cloth would feel and I couldn't wait to try one on. I got a boner every time I thought about wearing them, and when I walked into the sporting goods store to get my first pair, I was totally hard in my pants! When I put them on I couldn't believe how sexy they felt. Anyway, I'll save the day I got my first speedos for a separate story. We went down to the pool the morning after our first night, an hour or so after breakfast.  It was my first time wearing my new speedos someplace public.  They were size 28 with blue and white stripes.  My boner showed clearly through the shiny cloth. The bulge came right up to the waist band. I had the strings tied, but I left them outside my suit because they felt uncomfortable if I tucked them inside next to my boner. Before I went outside, I stood in front of the mirror in the bathroom and checked myself out.  I was a skinny kid with very fair skin, a mop of dark brown hair and a face that made people say I looked like an elf sometimes. The hotel had cool mirrors that let you see yourself from all sides.  I watched myself as I ran my hands all over the suit, enjoying the sensation of feeling my hips, butt and boner through the slippery material. As we went down to the pool, I walked a way in front of my mom to avoid letting her see. I was carrying a plastic air mattress for swimming around on, and a big towel which I draped over my shoulder so it partly covered the front of my suit. The pool wasn't too crowded, just a couple of kids in the shallow end and their parents on lounge chairs.  My mom picked a spot far enough away from the pool so she wouldn't get splashed while she worked on her tan.  I put my towel on a chair right next to the edge down by the deep end so I could get to it quickly and not have to walk past a bunch of people with my wet speedos clinging to my boner.  Then I put my air mattress down at the edge of the pool and slipped into the cool water. Swimming in speedos felt so sexy!  It was almost like wearing nothing only better because they were so silky and tight against my boner.  I tried swimming different strokes and decided the breast stroke felt sexiest because of frog kicking - moving my legs up and down, apart and together, sort of like humping the water. The water moving over them felt great. After doing that for a while I hung on the edge of the pool and stroked my boner through the front of my suit. The wet lining clung to my hard-on and the silky outer layer rubbed over it.  It felt awesome! I decided it was time to try out the air mattress before the pool got too crowded.  My mom had bought it for me right before our trip.  When I asked for it I had more in mind than just swimming around on it.  I thought maybe it would feel good to lie on it in my speedos.  As I climbed up onto it I found I had guessed right - for one thing, the plastic was very slippery when it got wet.  Another thing was the way it was made, with long narrow air pockets that went from one end to the other.  There was an indentation right in the middle, between two of the air pockets, and my boner ended up right between them.  It felt way sexier than I had imagined it might!  I immediately tried humping on it a little.  The slippery plastic cushion and my wet, silky suit was definitely a great new feeling. The air mattress had sort of a pillow at the front end for resting your head.  What I did was rest my elbows on the head cushion so my head and shoulders were held up, then I spread my legs real wide so my feet were in the water enough to frog kick.  Having the air mattress squeezed between my legs like that and moving my legs apart and together made my butt go up and down. It was great!  All I was doing was swimming around the pool like that - it didn't matter if people saw my butt going up and down because that’s what happened when I kicked my feet.  No one would know I was really doing. It was like what I did the day before in the hotel lobby, only even more exciting and sneaky.  I didn't have to go slow or try to hide it, I could just swim faster or slower to make my boner rub faster or slower through the thin wet nylon.  I could hump at the same time too and make my butt wiggle even more. I could even breathe hard, everyone would just think I was just kicking harder, trying to go as fast as I could. I went back and forth across the deep end like that for a little while, going slower, then faster, experimenting with the feel, adjusting the front of my suit so it felt just right on me.  I looked over my shoulder a couple of times to see how my butt looked in the suit.  The wet nylon totally clung to it, and little creases formed and disappeared as I flexed and relaxed on the cushion.  The material was just one thin layer except for a small piece in the front, so most of the white stripes had turned semi transparent when they got wet, and I could see my skin through them. Knowing how it looked made me even more turned on, and I imagined how cool it would be to see another boy doing what I was doing. I had the deep end to myself, and I kept going back and forth from one side to the other.  It was getting so I would almost be spurting, but then I would get to the other side of the pool and have to stop and turn myself around.  Then I had an idea. I would go down to the shallow end, then swim back to the deep end and try to do it just right so I would cum right when I got there. It worked out nicely, although I had to stop once in the shallow end to keep from cumming too soon.  Even though I had a great cover for what I was really up to, I still didn't want to have anyone right next to me when I got that awesome feeling.   After floating quietly for a minute, I was ready to start on my way back to the deep end. I pushed off the edge of the pool with my feet, then spread my legs wide and started to frog kick, slowly at first, then gradually speeding up as I went.  By the time I was half way to the deep end, I had settled into a nice rhythm of about one kick every second.  I figured I was far enough away from everyone, so I started to hump more as I kicked, and soon I was going hard and fast enough so my legs would occasionally make a rubbery squeaking sound against the wet plastic.  The feeling was coming fast, and I was breathing really hard.  Then, about ten feet from the edge of the pool, it happened - I gripped the air mattress tightly, my eyes closed, my legs thrashing and stiffening.  My boner felt totally huge and throbbing as spurt after spurt of hot slippery cum shot into my tight, wet nylon swimsuit. I was glad I was far enough away and facing the opposite direction from everyone, because if someone saw my total orgasmic expression or heard the little moaning sounds I couldn't help making, they might have finally guessed I was doing more than just swimming! When it was over, I continued to lay on my stomach on the floating cushion, resting my head on the pillow and paddling around slowly with my hands, catching my breath.  Later, as I swam around without the air mattress, I made sure I got all the cum rinsed out of the front of my suit - even the strings had gotten slippery with it! After a while, my mom called me from the other end of the pool - it was time to go back to our rooms and get ready for our day's outing.  As I climbed out of the water, I was immediately aware of how the thin wet nylon was clinging to me.  I was semi hard, and quickly became rock hard again. I was glad I had my towel close by, and I wrapped it around me as we went up to our rooms.
