Gaia's heels class begins with a sensual warm-up, her voice husky as she guides students through hip rotations and lunges. The room echoes with the clack of heels and the rustle of lingerie. Gaia, in a black bra and stockings, demonstrates a deep squat, her hips tilting, inviting students to mimic. Moans escape as students push their limits, hips grinding, breasts heaving, Gaia's eyes gleaming with approval, the room thick with arousal and the promise of more explicit instruction.
