Who you were before doesn't matter. You name will appear next to your production number, and its on your disclaimer you signed when you came here. Maybe you family needed money, maybe you had commit some horrible crime and felt this was your own repentance. Maybe you just felt empty in your life and wanted to contributed SOMETHING to the world. Your old name is about to not matter. Your owner will decide your name for you. Perhaps your old memories will be less than a dream. You'll never be thrown away or destroyed, that part of the contract was very precise. But your time as a human being is about to end. What your gender was before is about to not matter anymore either.
You signed three or five times that you were doing this of your own free will. You're about to be remade, who you were before remade from almost completely the ground up, with only the parts of your personality that'll serve your new purpose that will remain. You get the feeling that's what you wanted, that you feel this is a kind of freedom from who you were before. There's a great comfort in that, at least for YOU. There's no changing back once the change has been made. And you'll exist, alive and aware, virtually forever.
Now there's only one choice left that your own.
You have two doors before you, everyone goes through one of them.
One door is marked the Adults section. The transformation there are all pretty straight forward. You'll be a living love doll, your thoughts and ideas all focused around giving pleasure to your new owner. Maybe you've signed up to be a maid doll, or maybe the doll of a furry of any number of species, or a straight naked blondie, but no matter what, you'll be a living rubber balloon that's nearly indestructible whose reason for being is to give pleasure.
The other door is marked the Children Section. The transformations are very much more varied. But you'll be a toy for a child, and that's child's children, and great grand children, and great-great-grand children, through the rest of human civilization. A living fake fur and fluff filled plushie, a living plastic and hollow baby doll, a toy puppet whose world and life changed according to the whims of the child who played with you, you'd be humanoid, but that was about the only rule.
Maybe you'll go solo, maybe you'll be changed as part of a group (will you think of them as your brothers and sisters being 'born' at the same time?), whatever goes beyond those doors, you won't be able to change your mind later. You've already left your life as a human behind. Will you be one who exists to give pleasure to adults, or one who exists to give happiness to children? It's the last choice that belongs to you as a human.
You take off your clothes, toss them down the trash chute, and make your choice.
