Tony's fetish is Anne fucking other guys (and, if the opportunity arises, women). He lies to his wife by presenting it as an opportunity to reinvigorate their marriage, when in fact he's just cajoling her into fulfilling his fetish. At first he wants to be there while it's happening, then he wants to see evidence of/hear about it, and (at least in the previous version) he stops caring very much about either, as long as it keeps happening. Tony views his own extracurricular opportunities as entirely separate from his fetish, which is why he often fails to tell Anne about them. In all three versions of the game, Tony's fetish leads to both of them acting increasingly out of control and destabilizing the foundation of their marriage. It's not particularly difficult to see what the point of the game is, since it's been consistent across versions: it's about Tony losing control of his marriage, because he cares more about his fetish and his own selfish desires than he does about his wife.
