"Augmenta Mammae!"

Trinity O'Dowd, a Hogwarts Academy second-year student and a Gryffindor House member, sat in her dormitory, recovering from a nasty head cold. Trinity had heard whispers among some of her dormitory mates about a spell that could give a girl bigger breasts. Trinity, self-conscious about being flat-chested, visited the school library. She found a musty tome which discussed spells for various body parts, including female breasts. Trinity wrote down the spell's name and invocation instructions in her notebook, then returned to her dormitory. She sat down on her bed, unbuttoned her collared white dress shirt, and grabbed her wand. Trinity closed her eyes, said, "Augmenta Mammae!" and tapped her chest. She felt a pleasant warmth in her pectoral muscles and looked down at her chest. Trinity gasped. Her now-erect nipples sat atop two growing and wobbling fleshy mounds. The newly transformed breasts stopped growing when they pressed against each other. Trinity cupped her enormous mammary glands, marveling at the smooth, warm skin and the visible veins.
