In a dimly lit dungeon, a dominant woman takes a new slave through his paces, his cock locked away in a cruel, unforgiving chastity device. She orders him to stroke her to orgasm, his own raging hard-on a constant, torturous reminder of his powerlessness. She teases him mercilessly, rubbing her wetness against his face, whispering filthy promises of release that never come. His training continues, his orgasm denial a constant, excruciating lesson in her power over him.
