To me the levels so far have not been bad and kinda/sorta porn logic plausible. In this world and the real world, your boss and Friends can heavily influence and corrupt you into sleeping with them. Everyone can make a mistake, guys sleep with ugly girls all the time and regret it in the morning. Some women sleep with their bosses or hell their boyfriends best friend. Hell they even made a TV show called CHEATERS.
Alcohol is a culprit to people making bad decisions, people in this thread may not like it but it's true. People are susceptible to corruption, coercion, guilt, loneliness and make mistakes everyday. As long as they give us some PLAUSIBLE reason for her to continue getting wilder and sluttier I will be happy.
