Smooth Running

Running is Carl’s life. He trained every day of the year and lived for the marathon runs. There was one problem. Running causes some problems when done in the extreme. Chafing in the groin area was getting out of control and painful for Carl. What he needed was different underwear. He could only find cotton underwear in the men’s department. Lubricant only went so far. The chafing was so bad it drew blood and he had huge calluses on his crotch and the inside of his legs.

The solution was underwear made of anything other than cotton. Cotton swells when wet and it very course. Sweat turns it into sandpaper. After a particularly painful 20 mile run Carl was ready to try anything when he decided women’s underwear might solve the problem. Girls are so lucky their underwear comes in multiple fabrics. Carl bought several pairs of silk panties and prepared for his next run.

Carl could not believe how well it worked. Silk panties actually felt good while running. Another trip to the store filled Carl’s dresser drawer with silk panties. One day on his run he started to feel different. It was too late when he realized he was a woman! She kept running, bouncing breasts and all. He must have accidentally bought a pair of magic panties or a pair infused with TG dust or something. It did not matter. She had a smooth crotch now and no chafing when running. The next marathon she entered as Carly. Not all that original, but all she wanted to do was run, as a man or a woman. She did get more looks now than before so he rather liked the woman part better.
