So you decide to spy on her, in order to find her secret. When she stands up, presumably to go to the toilette, you decide to sneak behind her. Unforunately, she hears you. "Who is this sneaky girl overwhere? Oh surprise, it is you! With such a loud step, one might assume a heavy object stomps nearby. But it is only you. Time to adjust your body to your behavior!" Zip Zap, you are zipped again. You run to the next mirror, when you feel your body shifting. From the insides, you feel mass increasing, and as soon as you watch the mirror, you observe the outward changes. Your tits grow, but not only they but also your belly plops out, hanging down from your body. You feel a pressaure on your hips, pressing against your pants, your hips swelling. You can't afford to waste your last spell to bring yourself in shape again. You have to find out where your rival got her power from first. Maybe you need the last wish. It is much harder to walk carrying your body-fat, but as soon as you look into the next mirror you realize you look pretty cute don't you?
