Academically ambitious 18-year-old Stephanie Fox finds that she must transfer to a new grammar school in the middle of her A-levels.
On her first day at Stonemere Park Girls' Grammar School, Stephanie awakes to find her breasts have ballooned overnight from tasteful, discreet C-cups to… well, she has no idea.

Jolly hockey sticks, bitchiness, ill-fitting school uniform, and lashings of cum ensue.
