A college girl's world is turned upside down when her stepdad introduces her to a new form of domestic discipline. After failing an exam, she finds herself over his knee, her mini-skirt hiked up to reveal her perfect, virgin ass. He spanks her hard, no mercy, until her ass is a deep, crimson red and she's squirming with a mix of pain and unexpected pleasure. The rough, intense spanking is a harsh lesson, but one she'll never forget.
