You pause as you think about what you should change. 'The one part that matters' you think as you look at your pants where a very evident bulge was poking the front of the pants. Slowly pulling your pants and underwear off you sit on the toilet, your junk standing up tall as your pants and underwear pool at your feet. 'Take it slow...' You think, wanting to feel the change since it was just one part of yourself you were changing.
Clicking the flashlight into pink mode you lowered it next to your penis, carefully aiming it at you shined a dim pink light on it. Your cock shrunk slightly as your testes seized up, retreating slowly into your body as you continued shining the light on your penis, which slowly continued it change as you spread your legs to get a better look. The hole at the tip of your dick sealed up as your testes were sucked up entirely into your body, where they were going you had no idea. Your penis was soon just a tiny nub above your skin as a small line of dark flesh started to break on your flat scrotum, the fleshy cavity that was your new vagina opening up slowly as your dick was sucked up into it and rewired itself as your new clitoris.
Turning the flashlight off you looked at your vagina with a smile, putting the flashlight in your pants pocket so nothing back would happen to it as you slowly move a finger to tough your vagina.
The new sensation overwhelms you as you let out a slight moan from the feeling of your new vagina as sit in the bathroom stall, wondering what to do next.
