Instructor Madam Leda confronts you in her wetsuit. She's annoyed because instead of paying attention to her lessons, you've been horny over her and nursing a boner. So she is going to teach you a lesson and get you to masturbate in front of her as she instructs and tempts you. She strokes her snorkel, licks it as if it were your cock. You're ashamed but so excited at the same time as she orders you to cum while wearing her mask and snorkel.
