The metro's fluorescent lights cast stark shadows on the stranger's face as he expertly ties a blindfold around Sakuka's eyes. Her breath hitches, her chest heaving against the restraints. He whispers commands, his voice a low rumble, guiding her into a world of sensory deprivation. She feels his touch, light as a feather, tracing paths of fire on her skin. The metro's rhythm pulsates around them, mirroring the beat of her own desire, as she surrenders to the anonymous encounter.
