[Aries] I got huge breasts in a slime mold

A timid, androgynous level-12 apprentice wizard wanders into the forest alone and stumbles upon a Body Injection Slime, a monster that molds its captive to fit its own voluptuous silhouette—a change that counts as neither curse nor damage, so nothing can easily undo it. The petite shota is reshaped into a towering bombshell with enormous, ever-leaking breasts, and an equipment trap swapping her staff for a cursed sign only forces the milk to overflow, turning desperate self-milking into an addictive new habit she starts wondering how to escalate with magic tools or monsters. When a costly dispel stone finally frees her, her cheerful rescuer knows exactly how she'll pay it back: bottling that Super Special Magic Milk, bust-size-up effect included.
