You stared at the diaper, there was no way you were putting that thing on, you might be her size (or humilatinly, about half a inch shorter) but you were still 18, and there was no way you were dressing up like a baby, you still had your dignity, "No," you replied, "I'm not putting it on," "But you have to," Jess replied, "All people are size, must wear diapers."
"Well, I'm not," you replied "But you must, you must, you must," Jess winned, "well I'm not, I'm Not, I'm not" you replied, Deliberatly mocking her, Jess began to pout, and looking at her cute face, you did consider doing it, but no, you stuck hard, "I'm not wearing a diaper," you said, "I'm not a baby," Jess continued to pout, but you held firm.
Jess looked at you coldly, "fine, if you don't put it on, I'm calling for mom, to force you into it," You paused unsure, "mom wouldn't do that," you said, but truthfully you weren't that sure, up to now you never thought your mom would shrink you, or give you to your sister, a lot of strange stuff had happened over the last few days, and you were worried, what if she did? Sure putting on a Diaper was humillating, but being forced into one, was ten times worse.
"I will scream," Jess said, and looking at her, you were sure she would, you only had a few minutes, what do you do?
