Breast Friends: A Breast Expansion Story

No one's boobs could compare to Moira's. She started growing in freshman year, and while every one watched, Moira grew and grew, her breasts getting larger and larger until she was the biggest girl in school, and even then, she didn't stop. Now, she's graduating as a double-H cup, while her best friend, Elsie, never moved past training bras. Now, that's about to change. Elsie and her friends have been scouring the internet for cures for their flat chests.
They've found them, and now Moira, the bustiest girl in school, is in deep, deep trouble.
