Cupcake's shiny strap-on catches the light as she struts in her fishnet lingerie, her student's eyes glued to her every move. She begins her lesson, her voice a sweet, seductive melody, guiding him through the perfect jerk off. She shows him how to grasp his cock, how to stroke with just the right amount of pressure, and how to use his other hand to tease his balls. With each instruction, his cock grows harder, his breath comes faster, until Cupcake's encouragement has him spilling his load, a satisfied grin on his face.
