You wake up in a strange laboratory, restrained and helpless. A beautiful surgeon notices that you've awakened and explains what's happening in excruciating detail. You've been selected for our modification program. The procedure will be lengthy and even a bit painful, but by the time we're done with you, you won't be a male any longer. Instead of a cock, you'll have a beautiful pussy. You'll have enormous tits to play with as well! We're also altering your body chemistry to make you crave sex all the time. You won't just be a woman - you're be the best, horniest bimbo ever!
