"Now, under the water, you'll learn to pleasure me," the teacher commands, her voice muffled by the liquid embrace. The student nods, taking a deep breath before descending. She parts her lips, enveloping the teacher's cock, her tongue dancing along the shaft. The teacher's hands, visible only by their ghostly outlines through the water, guide her head, setting the pace. Up and down she goes, creating a hypnotic dance, the water shimmering around them. Surfacing for air, they lock eyes, the student's lips glistening, before diving back down to continue their forbidden, underwater lesson.
