In a dimly lit dungeon, three maitresses, skilled in the art of discipline, gather their submissive charges for a lesson in chastity. The amateur dominatrices, clad in black latex and armed with whips and crops, guide their eager pupils through the painful pleasures of orgasm denial. One by one, the subs are made to strip, their vulnerable bodies trembling with anticipation. The maitresses' expert hands and cruel implements leave red welts and gasping moans in their wake, as they meticulously train their charges to resist climax.
