You notice a metal machine wrap around your masculine anatomy. You remember why you're here, forgetting about your horniness, you know you're leaving this place with a pussy.
You feel as the bottom of your dick splits open and you can feel as your erection falls out, your very erectile tissue has been stripped from you, your arousal is not gone (though this is a turn off), just the anatomy that reacts to it. There's no pain, just an incredible uncomfortable feeling of loss.
Soon your urethra also leaves your penis, most of it is gone but you still have a bit between your legs, just like a girl. Your scrotum then splits open, you're not sure if your balls went up into your body or have been expelled from it but you're rather uncomfortable.
Finally you feel your penis head shrink into a clit and the skin form into feminine lips. If you could see yourself you'd probably have all the female parts except for the entrance.
You notice that you're skinny and pale just from the physical trauma of what happened. Making the change even more humiliating.
You then hear the words "Beinging final phase..."
