>Rushia casts a spell with the effect of transferring fat from Marine to Rushia's chest>Marine gets a slim (but still curvy) figure, while Rushia gets the tits she always wanted>but of course something goes wrong>Marine starts to feel invincible from her unchanging physique and goes on a massive binge, her stomach never feeling full no matter how much she eats>the magic spell is usually like a invisible beam of energy focused directly on expanding Rushia's breasts>but with the overload of calories, its now more like a firehose spraying all over her, causing her entire body to swell rapidly
