I swim for exercise. I wear jammers. Jammers are made of the same material as regular Speedos, meaning they stretch out and become unsupportive after a time, and need to be discarded. However, I recently discovered that if I let the jammers wear long enough, they stretch and the material begins to separate, meaning you can see right through them. So now my preferred pair are a VERY old pair that, when I pull the front guard aside, are virually transparent in the crotch area (see picture). I cannot be accused of exposing myself, as I am wearing an actual bathing suit. As I am swimming, I imagine that the woman in the next lane can see my cock with no difficulty, and I turn her way whenever I can. I have recently gotten more daring and gotten out of the pool this way and walked to the locker room door, often with dozens of people in the pool area. I am nonchalant about it, but I am jazzed inside. I keep working on these jammers to make them even more transparent. Maybe one day they will split while I am swimming and I will have to walk to the locker room with my cock hanging out. What a thrill that would be.
