This experienced mistress believes in progress as firmly as she believes in pain. Her dark dungeon looks like some weird laboratory of an evil-minded professor and every day she keeps inventing new torturing methods to use on her gorgeous
female slaves. Poor helpless girls get their cunts, nipples and asses tortured in new unpredictable and always extremely
painful ways. They suffer like never before and their prayers, screams and tears inspire the mistress to invent more and
more horrible torments for their tender pain-addicted bodies.
