In the heart of Taipei, a new gay slave is introduced to the art of fisting. The master, a stern yet experienced dominant, begins by warming up the slave's hole with a thick dildo, slowly stretching his tight muscles. The slave, bound and gagged, moans in a mix of pain and pleasure as the master's lubed-up fist pushes deeper inside him. The Taipei dungeon echoes with the sound of flesh slapping against flesh, as the master expertly plays the slave's body like a musical instrument.
