A fit, experienced trainer takes on a new student, a slim, tiny teenager with a baby face and a surprisingly insatiable appetite for his sporty instruction. As they go through the lesson, the instructor can't help but notice her tight, tiny body and the way her uniform clings to her every curve. She, in turn, is drawn to his rugged, muscular form and the authority he commands. Soon, the lesson evolves into a different kind of workout as the trainer fucks the super teen, her tight pussy stretching to accommodate his thick cock.
