Story 10

I am a male, who likes TF stories. I know my girlfriend would not understand. I was on the road on a business trip and had a day off break. I checked the Storyteller Blog, so I decided to check it out. The Stories was good, but after a while I had to use the bathroom. There was a waiting line to get into the men’s and women's bathroom. I noticed a third bathroom labeled changing room so I decided to use it. When I entered, it was no different than any other bathroom, stalls. Once I entered a stall and locked the door, I heard the entrance door lock and the lights went off. I felt my body start to change, it happened very quickly, I couldn't move. All I could tell was my body was changing into a female. With breast, long hair, and a lot skinnier and smaller.. The lights turned back on and I saw that I was changed into a she. My clothing had changed to that would fit my new self and size. What was I going to do and how to explain this to my girlfriend?
