I've always been sort of jealous because women can show off so easily and it's acceptable but guys can't lest we look like perverts or gay!
One day I was in a sports shop and saw a really sexy pair of running shorts made of a sheer nylon material with a lining to keep them "decent". I have to admit that I got a little hard feeling them and dreaming of wearing them. It shocked me to have this reaction so of course, I bought them. That afternoon I went for a bike ride wearing them and yes, they were sexy and yes they excited me to wear them.
I caught several women and even a few men looking at me. They were still not really as see through as I wanted them but the outline and bulge of my very large cock was clearly visible. I had found a fetish that I loved! Wow, I thought as I caught the occasional stare. This was the most incredible feeling!
I went home and thought about that afternoon. "if the shorts were just a little more transparent it would really be great", I thought. So I decided I was ready for the next step. I gently cut the lining out of the shorts leaving only the outer shell which was very sheer. I then tried the shorts on and modeled them for myself in a full length mirror. I was afraid they were just too sheer but it was still very exciting!
The next day I went to the beach wearing the shorts under another pair of gym shorts. I decided that I'd try sunbathing in them on a towel on the beach which was very busy with foot traffic this time of year. Once I got to the beach and settled into my usual spot laying on a large beach towel, I removed the gym shorts and laid back to enjoy the feeling of the sun and my near naked exposure to others. Of course my dick was extending down my leg a little and the shorts were barely long enough to hide the head from peeking out.
