When I was 14, once a week we had to attend swim class at Junior High. It was nude boy's swim. We were not allowed to wear a swim suit. It was completely naked! We were forbidden to wear anything. This was my first experience in public nudity, and it was quite exhilarating, erotic, embarrassing and scary all at once. It was one-hour a week of forced nudity. I will describe the experience in full detail. I would enter the locker room – through double rooms. The first room was quite small – sort of an antechamber or entrance room. I would quickly pass through this room. I then entered the locker room. It was quite large with several rows of double tall steel gray lockers. I would locate my locker and open it up with some apprehension. I could feel the cold steel latch against my fingers. It was empty. First I removed my shoes and socks. I put one sock inside each shoe. I placed the shoes into the locker. Then I began to unbutton my shirt. Nervously I fingered each button. In a second my shirt was open. I took it off and hung it onto the hook in the locker. I felt my bare feet against the cold tile. Next, I opened my belt buckle – then opened the button on my pants...I carefully unzipped the fly...took a deep breath, and slid off my trousers and underpants. In the flash of a second I was naked! I quickly hung the trousers with underpants inside on the other hook in the locker. I pushed the metal door shut. I stood there for a moment - naked. My testicles felt a breeze and nothing was covering my naked butt. Such a feeling of freedom, a bit scary too. I felt vulnerable – exposed – as you might feel when you're naked in a dream – except that this wasn't a dream. I felt naughty too. I turned around and walked towards the showers. We had to shower before we entered the pool. There I was totally naked at my school! So strange! I was surrounded by many other naked boys. So many delightful white asses. I felt myself attracted. It gave a thrill to look. By age 14, we were all mostly developed with pubic hair and full-size penises. I made a fast rinse in the shower and headed towards the pool. A double door to push open. We were about 40 teenage boys...sitting naked by the side of the pool waiting for class to begin. I felt my naked butt against the cold tile. I glanced at the other boys. Some glanced at me too. The PE teacher entered to pool area. Mr. Wright. Not a nice teacher – mean, often angry – a sadist, a bully. He ordered all of the boys into the pool. I jumped in with the other nude boys. We started with a free-style warm-up. I swam the length of the pool, doing laps back and forth. My body eased through the water like a dolphin or a fish. I experienced a delightful, delicious feeling as the cool water entered between my ass cheeks and ever so gently caressed my exposed anus. Mr. Wright blew his whistle. He ordered everyone out of the pool. I made my way to the ladder and climbed out of the pool. I immediately felt the cool air on my body, especially on my nude ass and testicles. With the other boys, we formed five lines. For the remainder of the class we swam races against each other, interrupted by Mr. Wright's yelling and whistle blowing. My body seemed to enjoy the feeling of standing in line naked just inches away from the next nude boy. Some of the boys misbehaved as 14 year old boys sometimes do. They didn't listen to Mr. Wright's commands or the roughhoused too much. I can't quite remember. At the end of class, Mr. Wright always left about five minutes to punish the evil doers. He ordered all of the naked boys to one side of the pool. He told us to sit down. I sat down on the cold wet tile. I again felt coolness on my naked butt, and noticed that my public hair was wet and matted down. He called the names of three boys. They stood up, and walked to the other side of the pool. Mr. Wright awaited them with a Styrofoam kick board. He ordered the three boys onto their knees, doggy style. He held the board high in the air; bit his lip, his red face with anger. Then with a sudden flash – smack – he hit each boy's naked white ass with the kickboard. Smack, smack, smack. Each boy was hit 10 times. They barely moved, but their exposed ass cheeks turn a pinkish red. No tears. Oddly they seemed to enjoy it. Punishment over. Mr. Wright blew his whistle and ordered all of the boys to the showers. The punished boys joined the rest of us as we formed a nude line into the showers. I quickly showered, and dried off with a tough white school supplied towel. I hurried to my locker, and removed my waiting clothes and shoes. I dressed quickly. With the other boys, I pushed through the doors rushing to my next class. That night lying in my bed, I eagerly masturbated remembering my afternoon of forced nudity.
