Instructor Madam Leda is aware you are worried about snorkelling. The prospect of breathing through a snorkel in water concerns you. So she briefs you in class and then, in the intimacy of her bathroom! And you watch and pay attention carefully as she is naked, lying face up in her bathtub full of water showing you that she can breathe perfectly well through a snorkel with her head immersed. And Instructor Leda seems to be ecstatic as she breathes and runs her hands down herself.
