Rarity was always a mare of romantic inclinations. With no shortage of failed attempts at relationships, she often obsessively tended to her physique and appearance. But when a poorly thought out plan leads to a magical backlash that turns the lithe young dressmaker into a butterball of marshmallow flab, she thinks no pony could ever love the new her.

Little does she know, there was one pony that had always cared for her. There's only one problem. She's Pinkie's sister, Maud Pie.

This is my first submission on FIMfiction, and will involve my favorite of all ships, RarityXMaud. And also fatness. I decided to go ahead and rate it mature for possible later chapters, which may involve sex. And possibly futas. And possibly farting.

Enjoy!
