DaraJaney,
Wow! I read your last 2 chapters thoroughly twice so I could really appreciate each and every indignity Jake and Janice suffered!
I imagined myself in Jake's dress and nappies, having to waddle up the steps, then pooing my huge nappy and having it announced to the world, followed by having to do the waddle of shame in my nappy now thoroughly wet and filled with heavy squishy poop that moved around with each step. Instead of mommy changing me, I had to be in the care of my and Janice's former classmates who took joy in mocking us while we were in line for the changing tent. With no doubt, we received at least one swat on the seat of our nappies, further spreading the squishy poo inside and increasing our discomfort.
At least I was changed in a tent with only a few girls to see and giggle at my locked chastity device. But after that, after I was denied a little candy floss, I was very publicly breastfed by Mrs. McKean and my own sister, enjoying the candy floss that I couldn't have, announced to all that my boy parts were under lock and key.
Then it was back to the stage for further humiliation, capped by being strapped into my stroller up on the stage next to Janice, with both of us on full display for all to take photos and videos, knowing that we would be featured in newspapers, television, and internet podcasts and blogs. I think at that point we would lose all control and cry the most we ever have in our lives, being so upset that the breast milk from Mrs. McKean sped through our digestive systems so we both wound up being stinky babies in soiled nappies again, this time sitting in our mess. After the eventual waddle of shame down the stage steps again in a filled nappy, I would hope that our mommies had brought enough nappies so we wouldn't have to endure a derision-filled uncomfortable stinky trip home.
I don't know if this would be too dark for this story, but since Janice is on birth control, is it within your realm of story possibilities that she may start lactating? If that happened, would Mrs. McKean continue breastfeeding Janice only, and would Jake be dependent on Janice for his nutrition?
