I'm trying to recall any unavoidable non-con scenes, and drawing a blank. In my experience playing this game, every non-con, assault, rape, etc scene was always something you could get out of. The dream sequences have absolutely no effect on the rest of the game, so if you don't like the content in them, it's pretty easy to just.......hit ctrl and skip them.
Dude, it's a single boob grope, and your character can almost immediately stop it by decking him across the face. If you weren't expecting any potential non-con stuff on a game that literally presents itself as having Corruption, Prostitution, and Bimbofication, then that's a you problem, and you should probably start wearing a helmet from now on.
