"I... I don't know what to say." You start.

Rachel stands there, her newly overweight body glaring back at you, bewildering you both. She was her normal, thin self yesterday, but now she's blimped up in size! Her hips much wider, belly bloated and pushing against her sweatpants. Her top rolled up her gut, exposing soft, white flesh. Her breasts, arms, face, and neck, everything about her looked bigger. Yet it settled on her body quite naturally, you could hardly tell this wasn't normal. But you both knew.

"I don't know either! This just... happened last night!" She says, gesturing dramatically to her expanded form in frustration. She had called you earlier today asking for help but not explaining why, and here the issue was, jiggling about as she panicked. How could you possibly help her?
