Mischievous Satine gets booted from summer school after a skinny-dipping escapade with a boy, much to the dismay of her overprotective stepdad, Jay. He’s baffled by this sudden rebellious streak in his usually discreet stepdaughter and overwhelmed by the responsibilities he has to endure now that Satine is out of summer school. After some gentle (and not so gentle) arguments, Satine confesses the truth: she was simply curious about sex and, more specifically, the mysteries of the male anatomy. Jay, a man who believes every life lesson can be taught through unconventional means, decides to scold her. He unravels a kinky plan to "educate" Satine on the basics of male anatomy and pleasure, a plan that involves everything from oral lessons to actual penetration. As Satine navigates her stepdad’s awfully practical lessons, she learns more about her stepdad's sexual prowess than she ever expected.
