A college student, eager to supplement his income, signs up for a mysterious medical study. Upon arrival, he's surprised to find the doctor is a handsome, muscular man with a twinkling gaze. The doctor instructs him to change into a snug, spandex outfit, claiming it's for 'scientific purposes.' As the student shifts, the fabric snaps against his skin, and the doctor can't help but bite his lip, his professionalism wavering. The student, feeling the doctor's gaze, grows aroused, his cock straining against the tight material. The doctor, unable to resist any longer, moves closer, his breath hot on the student's neck as he whispers, "Let's explore your physical... in depth."
