A brunette's music lesson takes an unexpected turn when her instructor, Joaquin Sabina, introduces a new instrument - her own body. She tentatively takes his thick cock into her mouth, learning to bob her head and swirl her tongue around the sensitive tip. Her inexperience leads to some gagging, but Joaquin patiently guides her, his voice husky with desire. As she begins to master the art of deepthroating, she feels his hands on her ass, pulling her onto his lap, and she understands the true lesson of the day.
