A wonderful commission by HofBondage

the girls from Crystal Prep Academy are trying to sabotage Rarity's efforts to create outfits for her team's dance competition because the Crystal Prep girls want to win instead. The Crytsal Prep girls text Rarity from an unknown number, claiming to be Fluttershy. The text says Fluttershy has found the most wonderful addition for their team's outfits, and asks Rarity to meet her at the mall.

Rarity is cautious, since she doesn't know the number, but can't pass up an opportunity to keep the upper hand against her rivals for the dance competition. She goes to the mall, and to her surprise, finds the destination to be a baby store. Seeing no Fluttershy around to show her this "wonderful addition" Rarity becomes exasperated, muttering about how punctuality is important. Rarity turns around to leave, only to bump into the Crystal Prep girls instead. They quickly apprehend Rarity, and pull her into one of the back corridors of the mall. The girls snicker at Rarity's struggle, knowing Rarity can't overpower them. With almost no effort, the rivals quickly tie Rarity up with a giant poofy diaper to boot!

The Crystal Prep girls leave Rarity faceted to a cushy baby crib, struggling to break free from her bondage to no avail, with a note pinning her skirt to her shirt that says "Baby Rara #1 outfit design ❤"
