"I'm just giving you what you deserve. You will become a bird," she says with a wide smile.
You have no time to protest. You start growing but slightly. Then your skin erupts in feathers. Your bones snap into new positions. Your arm bones elongate and lengthen. The bones of your hands fuse into many less. Your legs become scaly and clawed, covered in black scales. Your nose and mouth protrude and harden, forming a little beak. Your eyes become round and black. Your ears vanish into your skull, retracting completely. The feathers of your new avian body are grey, brown and white.
"No! No!... I... Peep! Peep!"
You flap your wings wildly, trying to get to grips with the different organs your now possess as well as those that are completely altered or have vanished. You believe you are still female and reel under the disturbing thought that you will lay eggs at some point. In truth, the fairy made you male again, it's just that male birds do not have testicles or penises, or anything hanging in the breeze. They have a cloaca which serves to urinate, defecate and produce sperm. If you wanted to mate with a female sparrow, you'd have to rub yourself against her own cloaca while mounting her. But for the moment, you are trying to come to terms with the fact that you are a bird, a small bird, that you can fly and that your life will be very different.
"You don't seem very happy to be as free as a sparrow," mocks the fairy. "And I made you male again, besides giving you the ability to fly, a long human dream, I believe."
She waves her hand again and a bird cage, rather small, materialises around you. She grabs the top and leaves, saying that she'll sell you to a fay trader who will put you on display so as to attract customers interested in buying you. Not so much because you are a bird but because as a human first, you are easy to transform, making you fun for fays to make you into a pet or a child to adopt, or just the perfect being in their eyes. You can only chirp in indignation and protest.
You chirp anew, even as the fairy is offered shiny gems by the ogre trader who just gives you a bowl of water and some bread crumbs before leaving you, a note indicating you're a former human. He joked with the fairy that a transformed human, now a bird, is easier to look after, clean its cage and feed than in his original appearance. You can only tweet in response and be ignored. And as you are ignored by the big fat ugly ogre going about his store, you wonder with apprehension who will purchase you. And for what purpose.
