As you walked through the halls of your school, a young woman grabbed your shirt and slammed you against the wall. Although she was shorter and more petite, she held you against your will, staring at you with a look of utter superiority.

"You thought the 'swap class' was a game, right? Well, today you're going to learn a real lesson. Give me your body... and don't worry, I'll take care of your life from now on."

In just a few seconds, a wave of sensations overwhelms you. The world tilts, your vision blurs, and an unexpected tightness presses against you. When you open your eyes again, the world is completely different.

Your body is now shorter, lighter, and the clothes that are too big for you hang off your shoulders. Your hands are small and delicate, and for the first time, you feel the discomfort of a bra. Fear makes you stagger, and a scream escapes your mouth, but it's not your voice; it's a high, delicate voice.

"You... don't move, asshole," his voice sounds deeper, richer, and more powerful, as if your body had been waiting for it. "Don't worry, in a few days you'll be the prettiest girl in school, but don't forget that your body is mine now."
