The Dragon's Hunger

You pick up the bottle, uncorking it and chugging its contents. Suddenly, you feel an odd sensation around your middle. You hear a loud gurgle come from deep within your stomach, and suddenly your middle presses outwards. Layer apon layer of doughy fat is added onto your midsection, making it hard to walk. You stumble, then plop down onto your rear with a loud thump. Your gut is growing, and shows no means of stopping. You begin to purr, groping and kneading your expansive stomach in a state of tranquility. Suddenly, the growing stops. Someone emerges from the shadows in front of you, carrying two immense jugs of the pink potion.
"Ah, I see you're enjoying yourself~" she teases, setting down the jugs to squeeze your belly.
