A glamorous boss commands the lens in “solo massage.” After hours, she locks her office door, hikes her pencil skirt, and records a ruthless performance of power and pleasure.

Every order she gives the invisible viewer becomes wetter, dirtier, until she comes with the city lights glittering behind her. “solo massage” is dominance wrapped in expensive lace.
