Note how there is no blackmail tag up there? I'm guessing the devs have made the decision that this is not that kind of game, as in there will be no blackmail or non-con content. I'm fine with that, frankly. She has other reasons to go along, such as money, her own lust for big virgin dick or Nick getting too close to a masseuse.
However, Nicole stringing her along on several occasions annoys me a bit. Nicole is that cliché slutty character that must be in every game to get things moving, and that bores me a bit. The double fuck scene went a bit further than we have seen before. However, the reluctance that
@roflcopter mentions is based, I think, on the fact that Lily still doesn't want others to see her cheating, especially Nicole. Frankly, I like that.
I really think the writing in LotV is better than in most other games like it. The scenes and situations are inventive and sexy. Sure, there are mistakes here and there, but no major plot holes, imo. LotV is often compared to Anna Exciting Affection, and that game has long since lost any plot or direction.
