A mysterious epidemic has swept across the world—every girl is getting bigger. Taller, wider, heavier, and seemingly more confident with every passing day. The source appears to be the sweets from "Madolce Bakeries," a company that has popped up everywhere, offering irresistible treats that cause anyone who eats them to balloon to incredible proportions. You are a young man trying to survive in this new world, where you've become the favorite target of your ever-expanding best friend Ruka and her growing circle of massive friends. Every day brings new opportunities for you to end up flattened, smothered, or completely buried under mountains of soft, jiggling flesh. The only hope is uncovering the truth behind the Madolce epidemic—but that means getting closer to the very women who keep trying to squash you.
