Extend the Story - Add a Room

It seemed like forever before the noise stopped and Pinkie appeared to back off. She stood up and wiped the sweat from her brows. "Phew! Boy am I glad that diaper did its job! If that were one of the twins' diapers, that would've been really messy."

Twilight, meanwhile, found herself trapped in Pinkie's log and powerless to escape despite her best efforts. She was at least grateful that she was in a diaper and not a smelly toilet, she didn't want to end up flushed into the sewers (assuming she survived the trip down).

"Twilight, I'm so sorry. I'll find a way to get you out of there," Pinkie called to the diaper as she got up. "But for now I really need to get changed, if I don't I'm gonna get a rash." She trotted out of the stall and to a nearby mare sized changing table, climbing up onto it and laying down.

The squishing only further trapped Twilight, who now found herself in need of going and with no forseable way out.
