In a private tutoring session, Professorudia's student finds herself on the receiving end of an unconventional lesson. The professor, with a glint in his eye, instructs her to masturbate, using the explicit term 'punheta' to describe the act. She's hesitant at first, but as the professor's deep voice guides her, she begins to touch herself, her fingers delving into her 'buceta', rubbing and stroking until she's panting, her body writhing with pleasure.
