The pain takes over for several seconds. Not only do you bleed from the cutting off of your parts, you feel something spread up into your body as you begin to change. Eventually the pain starts to fade. As soon as you can move without being in agony you get up and look at yourself. Something has happened. Between your legs is the unfamiliar form of a feminine pussy and clit... and from what you felt the change is more than just on the surface. You have a full woman's system in a still-male body.
You run down a path, looking around in the hope that your missing parts are still there and can be attached to reverse the transformation somehow....
