you can get some of her scenes in the brothel, but to get the rest, you have to be rough with girls (its easiest to pay them so blow you, and fail a charisma check when you ask them if you can cum in their mouth, then just forcefully do it twice) after that you will be banned from using brothel workers and if you go to the town ball during the day, you will get approached by lura, you will have a mouth piece check (the ring gag) and if you have it she will take you to the alley and fuck your mouth, make you her slave and being you to the castle (its an ending) and if you fail it, you will have a perception check i think, and if you fail it you will be drugged and taken to the castle where you as a player will have as much fun as will lura have, but your char will not xD
