Bella has been very naughty, and taken off her wet diaper and just left it on the floor while she sits on the bed sucking her thumb. There is even pee on the floor, and Mommy has to wipe it all up. She's not happy!
Bella just thinks it's funny, and insists she's really a big girl and doesn't need to wear a baby diaper, even as she sits there on the bed sucking her thumb and with pee pee all over her pussy. Mommy has different plans. First Mommy has to clean all the pee pee from between Bella's legs and then struggles to get Bella into her first diaper. It's not an easy job, as Bella squirms and struugles. And as soon as Mommy has got it on her, she starts to rip it off!
Mommy is really cross, and puts Bella into a second diaper, right over the top of the first one, making a lovely big bulge between her legs. And for being so naughty, Bella is made to sit on a chair until she learns how to behave. At first she seems happy enough to sit there and play with her toys, but it's not long before she's back on the bed trying to take her diaper off again.
So it's back onto the chair for Bella! She makes a very sad but slightly comical picture sitting there with both thummbs in her mouth, just like the baby she really is. No way is a Bella a big girl yet, and no way is she ready to be trusted without a diaper!
