One in episode #6 has already been reported in the topic "Winter Anime Series." Here are the rest -- and I would describe them as rather grim:
Episode #9 - first around 5:00 Maria has her hands tied overhead (NSFW warning: attempted rape scene), then around 9:00 her wrists are in stocks and she has a strange metal gag.
Episode #10 - first around 4:30 Maria has her arms roped behind her and is suspended from a rope, then starting around 11:00 is a succession of scenes: Maria with her wrists in stocks in front, then behind supplemented with chains, then chained to a stake for burning.
