"You obviously need some re-education in this matter. Teens are very stubborn, I know, but I'll take care of that..." She waved her hands, cooking up another spell and once again you see this strange blue glow. Your firm, defined body starts to lose muscle mass as you see what seems like the lady getting taller, but in fact is you getting shorter. Your bulbous chest recedes back into your body until you are entirely flat-chested and your features have become a bit rounder and puttier, your body shrunken to about half its size and surprisingly, the dress as well. Within a few moments, you stand at a fraction of your original body in a children's version of the dress and a colorful hair tie that holds you hair up in a ponytail, your entire maturity reversed. "Whaa! What did you do?" You shout in a even higher voice than the one you had.
"Since you obviously have no understanding of the full experience of womanhood, you now have all the time in the world to learn about it. Servitude is a big word for your current situation, but you'll be definitely living in for years to come."
You can't believe it. For years to come, you're going to be bossed around by this woman as a little girl. But hey, at least she has a nice house.
