Nothing too advanced. As of now I'm just changing some of the scenes already in game to be a little bit more "revealing", as well as adding in a few extra options/scenarios.
For example, during the first sex scene with Eric if you choose "Fuck Hard" and then refuse to be quiet, Arthur will walk into the room. From there you can tell Arthur to leave/jerk off/or fuck him depending on your karma level.
However, these new scenarios are just edited versions of already existing scenes and don't really affect the story atm.
