Woke up with a cock - gender transformation

I wake up and as I put my hands under the duvet I feel something in my panties, it feels very odd. I peek under a duvet and cant believe my eyes, I seem to have a cock! I pull the duvet to one side and there it is , a bulge in my panties, a cock and balls!! What is going on, what do I do. After lying around a bit and getting over the shock, I start looking at it and playing, before I know it, it's got hard! Well I might as well find out what it feels like to stroke it, I get more and more carried away, this feels good, I taste my own precum, this is so hot. I keep stroking until I cum, that felt so good!! I end up tasting my own cum too, it's so delicious I'm licking it off my fingers!!
