For those looking for NTR: The creator uses the broad term for NTR, and in 90% of cases, its more akin to sharing/hotwifing, as the women are ultimately corrupted by you. Although, for more direct NTR, one of the main women Lydia is more who you are looking for. Like the character's Jen/Mel/Atonia you slowly grind away at the character, making them more and more slutty. However, Lydia out of the bunch is probably the weakest willed, in that she loves being dominated. To this degree she is the only one with a substantial amount of scenes/dialogue where she allows herself to be claimed by other men, and admits to being theirs. She is also the only character who has a late game activity every friday, where you basically find her cheating, and her mother tries to play interference. Again it's hard to say its pure cheating, because to get to this point you push mostly her lewd activities, and basically throw her into porn, and allow her to keep the #'s of the men she performs with.
Personal comments: As probably the final major content update for Lydia, I feel slightly conflicted. I'm glad the party mechanic finally has an ending, although it feels like it has less options, but remembering when this game got started, and when the original party mechanic came about, it has been some years. More so the Dev needs to/should wrap this up so they can push more expansive/better content for sins. If I had any requests as far as Lydia's character, it would've been to have us the player really nail down to her whether or not we continue with her overall loss of control and whether we continued to allow it. I also wished the angle where Lydia reveals her first BBC being with an ex of her mother's was played out as an event on friday. In that it was actually someone christine was actively dating, and we had choices to steal christine from him, but at the loss of him stealing time with Lydia. And Failure to show up on friday's, meant he got time with both women.
Good update, sad to see it's almost over. It was probably one of the better html games, even if it has become a bit bloated and crude, it was a decent product. Hope sins of night can eclipse this!~
