An innocent female trainee works at a demolition site full of men. Her "training" is a brutal sexual training session to master the use of a giant piston vibrator. Amid the sounds of heavy machinery and the smell of oil, rough men strip her of her trainee uniform and humiliate her as they jerk her all over. In a corner of the site with no way to escape, she is forced to orgasm with a powerful vibrator, and her reason begins to crumble. As she straddles a cock and accepts a creampie while covered in sweat, as a baptism into a man's world, her eyes gradually begin to show submission to pleasure. A wild eroticism blossoms in a grimy workplace.
