- bath masturbation scene added;

- Added 1 new scene to Catherine's pool of random nightly events;

- Added some extra/different dialogue for having the bimbo or masochist or exhibitionist traits during the "slave competition";
- Added a proper ending for the slave competition if you "break" your mind by accepting 2 or more times to get help;
- 1 new scene in the slave path ("celebration" for winning the competition);
- Added the piercings you can receive during the slave competition in the game (will probably remain exclusive to the slave path);
- Added scene for milking together with cows you helped capture (just Eliza for now, more in the future);
- Mini-quest on the slave path (turn the new slave into a GREAT slave, also triggers slave path end when completed);
