"Now, Maiko, Yuki and I have a lesson that we're going to teach you while you're here. That lesson is to not take things for granted. Why did you shoot me down like that? I don't really want to know anymore. That's in the past. However, I don't understand why you wouldn't want me. I'm perfect for you in every way!"
Naomi continued, pacing back and forth. "So I'm going to teach you not to take things for granted. It's as simple as that. When I asked you out, you hadn't learned this lesson. So I've brought you to a point in your life when several things you always take for granted are gone.
"You're a girl now, so your penis is obviously gone. The main point, however, is that you're only 18 months old. You can barely walk! You drool all over yourself! You can't eat anything without having it fed to you! And to top it all off, you pee and poop in a diaper - and you don't even know it!"
"Yep, she definitely doesn't know it," Yukiko said, holding her nose in disgust.
"Uh-oh! My little sissy May-May made a messy!" Naomi giggled excitedly, performing Maiko's first diaper change in a long line of more to come. "Now, to teach this lesson, you'll only be pooping your pants if you choose to. We're going to let you grow up, but you have to be ready for potty training. By the time you hit age 12 as my little sister, you should be fully potty trained, and we'll change you back to your normal, male self. But don't worry. Your aging will be accelerated, so this won't take 12 years. It'll probably take somewhere around two weeks at the least. However, if you still don't get the point when this is all over and you've retrained, then you'll be back to 12 months old, and you'll age at a normal rate as my new baby sister.
"Do you understand everything I've just told you?"
The toddler Maiko tried to say, "Yes, Naomi," but ended up saying, "Eff, Nomee."
"You're so cute! Now, we're just going to have fun today, and you'll start potty training tomorrow!"
