"Hi," a small voice said into your ear, causing you to jump out of your skin. You looked around, trying to find the source of the voice in what was supposed to be your empty apartment. A glint caught your eye in the corner of your vision, making you snap toward it. You jack became slack when you saw the owner of the voice. A tiny fairy fluttered just in front of you, a faint glow of magic emanating from her. "Oops, didn't mean to scare you," she said, holding her little hands up, "I've just been assigned to fix a clerical error." You just looked at her, bewildered by her presence and the idea that she was some kind of bureaucrat. She took your silence as a request to continue, "It says here you were accidentally marked down as male, but you were supposed to be female. Don't worry, I can fix this real quick and be on my way." Your mind raced with so many questions, but none left your lips before you started to feel a strange coldness overtake your body.
You felt yourself stiffen as the fairy worked her magic, shaping you into what the universe apparently meant for you to look like. You watched as flowing, pink hair cascaded down and around your rapidly softening face. Your vision began to blur before a pair of glasses materialized perched upon your cute nose. "W-what are you doing?" You gasped in a newly high-pitched voice. "I already told you," the fairy replied, genuine confusion as to why you didn't understand. Your clothes weren't exempt from the changes, restitching themselves from a white tee and jeans to a thick, fluffy turtleneck and a long black skirt.
You felt the new fabric with your delicate hands before hunching over as heat overtook your chest. You started to pant rapidly as the front of your sweater started to stretch. Moans and groans escaped your lips as more and more mass appeared on your chest, pulling the sweater taut. You poked at your rack, surprised by the sensitivity of your new breasts, before the sensation shifted down your body. The wind was knocked out of you as your waist caved in, instantly complemented by the rapid expansion of your hips. Flesh flowed into your rear and thighs, packing on pounds that forced your skirt to become snug. The alien feeling of your new curvy body was too much to process as the fairy started to talk.
"Looks like everything is cleared up here," she giggled, but you held up your hand to stop her. "Please," you begged, "Turn me back." "Sorry, cutie, but I can't unless you want to lodge a complaint," she replied. "Yes, I would like to have my original body and sex back," you asked, still shaking from your transformation. "Your request has been submitted, and you will receive your answer soon," she told you as if you were asking for something unimportant. With a puff of glitter, she vanished, leaving you behind in your buxom body. You could only hope that 'soon' really meant soon and didn't take a few more decades like the original error.
