Rita looked like she was having fun messing herself. Aaron wants to join in on the fun. And he doesn't want his best friend to be the only one diapered. He changes "pull-up" to "diaper". Immediately, his underwear puffs out.
Now that he has the appropriate protection, Aaron bends his knees into a squat. But before he can start pushing, he's spotted.
"No, Aaron!" The teacher rushes back and picks Aaron up. Desperate to have the experience he wanted, Aaron begins to push. But the teacher is too fast. In seconds, his butt is bare, sitting on a training potty. Aaron scowls at the teacher as he poops in the potty.
When he finishes, the teacher puts him in a fresh diaper and goes to check another kid. Aaron generates a new sentence, seething.
"The teacher is checking her student's diaper" is changed to "The teacher is checking her own diaper". Before his eyes, Aaron watches the teacher get a diaper bulge and discretely stick a finger down the back of her diaper. Good. But not good enough.
Aaron generates a new sentence.
"The teacher is glad her diaper is clean."
