My Tight Swim Briefs

When I was younger, I was really into swimming. I never joined a team or did it competitively, but I would go to the local pool on a fairly regular basis. The only time of the year I couldn’t go was during the winter, when it would be too cold to swim, even in the indoor pool - which didn’t have very good heating. I couldn’t wait for winter to end and spring to start so I could return to the pool!

In the first month of spring when I was 13, it was finally warm enough to visit the pool. I excitedly packed my towel, water bottle and light blue swim briefs into a small bag at home. My dad offered to drive me to the pool and pick me up when I finished. At the pool, I said goodbye to my dad and thanked him for driving me, telling him I would call him when I was done. I paid for pool entry and hurried to the boys changing room. I stripped off my t-shirt, shorts and underpants and pulled my swim briefs on.

I had grown taller during the winter, so the suit barely fit me. The waistband was tighter on my waist than I remembered, and they showed off more of my skin due to my height. I went inside a shower stall to shower before entering the pool. The door had a mirror behind it, so I looked at my slim, light skinned body in my blue swimsuit while I showered. My sandy blonde hair flattened to a mop, reaching my shoulders. When I stared at my crotch in the mirror, I got the shock of my life! My wet swimsuit was so tight around my penis that a noticeable bulge appeared.

I tried to pull the swimsuit down to stretch the suit, attempting to make my bulge less noticeable. Every time I let go, the swimsuit would snap back at my penis and balls, providing me with a strange, tingly feeling down there. I had never felt anything like it before. It was like something inside me was building up and ready to be released. Despite my curiosity, I didn’t explore this feeling further. Instead I rushed out of the change room and jumped into the pool, swimming different strokes for about three hours.

When I returned to the change room and peeled my swim briefs down, I noticed a small white stain in the crotch area of my suit. I was nervous and embarrassed that something was wrong with me. I quickly changed back into my regular clothes, called my dad and went home. I threw my swimsuit in the laundry basket and went upstairs to my room. I went on my laptop and used social media, slowly forgetting about the incident at the pool.

A few days later, I was on my bed and it was nearly midnight. I had school the next day and was struggling to get to sleep. I tossed and turned in my bed, eventually staring at my closet. In the dim moonlight, I could just notice my light blue swim briefs hanging on a rack in the closet. I thought about what happened at the pool and suddenly I had the urge to wear the swimsuit. I turned on my lamp, and slumbered towards the closet. I grabbed the swimsuit off the rack and ran my fingers across the material. As I ran my fingers across the soft, silky material, the tingly feeling in my penis returned.

I returned to my bed, now lit by the light from my lamp. I stripped off my clothes and pulled my swimsuit on, slowly. I enjoyed the sensation as the thin material passed my feet, legs, knees and crotch. I tied the waistband string, leaving it in a bow inside my swimsuit. When the suit was completely on me, I reached down to the bottom, stretching it out with my hands, then letting it snap back at my balls. With each snap, my bulge grew and the tingly feeling inside of me started building up, flowing through all parts of my body, but mostly just inside my penis.

After three or four more snaps, I used my hands to touch my penis and balls through my swimsuit. The electric feeling was almost at breaking point, so I decided to quickly rub my bulge through the swimsuit. As I did this, I felt my body - which had been filling up like a balloon - start to burst. Inside my penis, liquid began to flow and reach the inside lining of my swimsuit. My body bucked and twisted, with my legs flying all over the place at this feeling I couldn’t hold back. I felt like I went through multiple spurts of white liquid before I could finally relax. 

When it was all over, I glanced at the crotch of my swimsuit. The light blue colour at the front of the swimsuit had turned dark, creating a large patch there. There was even a noticeable wet stain on my bed sheets! I was overwhelmed at what I had done that I just collapsed back on my bed. After a few minutes of staring up at the ceiling, completely still. I decided to masturbate in my swimsuit again and again. I must have been doing it for an hour before I was finally so tired that I fell asleep.
