Julia Reaves, the fiery dance instructor, commands the stage in her private salsa class. The room pulsates with the beat of the music as she guides her eager students through a series of intimate, provocative moves. Her hands grip their hips, pulling them close, as she teaches them to feel the heat between their bodies. The class, a writhing mass of limbs and desire, loses themselves in the dance, their inhibitions melting away with the sweat dripping from their skin.
