Britt, Kallie, and Penelope have always been A-students at school. However, senior year is here, and they want to experiment before going to college because they don’t want to be prudes. Their goody-goody image suddenly changes when the girls post sexy photos of them showing their butts inside the classroom on the first day of school. Mr. Mason, the school’s principal, gives them detention for it and decides to have a serious talk with them about their sudden change. The girls love Mr. Mason, as he used to be their favorite teacher last year, so they confess their desire to experiment before going to college. Trying to save them from bad guys and failing senior year, the principal decides to help his favorite students experiment sexually so they can get it out of their systems and go back to being the sweet school girls they were.
