You say "Thwee". She says "that's right, I am so proud of you!"
When she hugs you, she looks down at you.
She sees you are wearing underwair. "Honey, where did you get those?"
she said "you know that you wear a diaper"
The thought of you wearing a diaper passes through your head and you think "she's right, I wear a diaper cause I am special".
She picks you up and lays you on a towel that is laying on her backseat and removes your underwear and puts a diaper on you.
As the diaper is put on, you think "that feels better..."
She puts you in the carseat and closes your door and then gets in her seat and closes her door and starts the car.
As she pulls out you forgot that you needed to relieve yourself, but to your new mind...pooping or peeing on the spot is second nature...
Only a matter of time
