[WARNING: This story contains foalcon, diapers, heavy wetting, light messing and a very hands on trainer]

Babysitting Flurry Heart is always a highlight of Sunburst's. After becoming her Crystaller, he'd found that he loves laughing and playing with the foal, so much so that she's wandered into his thoughts after dark more than a few times, and the fact that her parents still haven't potty trained her doesn't help matters.

He's always dismissed his fantasies as nothing more than pipe dreams with no chance of becoming a reality, but her body is developing quickly, and Princess Cadence is eager to begin her training to help her grow into a perfect wife for her prospective husband.

Playtime just got a whole lot more... Pleasurable.
