Currently it's branched as two separate paths. I wish I could do both, too. Don't read further if you don't want spoilers. Kinda mentioned it before, it would be nice if you could get some love from Tina as well as
NTR, cause the way it is, she's a complete fiend and makes you feel like she doesn't care about you at all. This would be a good "punishment NTR" arc in a game where you didn't have so many other women to be with any time you want, but since you do have everyone else, you just shrug and let Tina do what she wants. Feels more like she claimed a free pass and Danzig didn't deny it, than ntr. I wonder if it could be more kinky if she still fucked Danzig as his girlfriend, but he caught her cheating now and again. Her taunts during those scenes are good, though, but the "how can you be surprised, after cheating on me with 20 different women" would sound more convincing if she kept a normal relationship with him. If he can't get her pussy, he'll just go for the others. She really should rethink her strategy, if she wants to be the top bitch in the harem, gotta give and take, not pretend that Danzig's a doormat that takes her seriously
Don't get me wrong, I like the ntr scenes themselves, it's just that Danzig's all "baby, I can't believe it, how can you do this", and next slide he's fucking his niece's ass. But it doesn't matter much, I still go for the revenge route, because there's plenty of romance elsewhere
One good thing is that
ntr isn't implied in the game until it happens (your fair warning says "she'll do unspeakable things" to Danzig). So players who actually don't check spoilers may get a pleasant surprise if they're not expecting it.
If you want to do both, I'd recommend you use URM and try to cheat into watching both. When you get the chance to pick your route with Tina, remember the variable/flag that gets set if you pick the dom route. Then make Tina submissive, and when you get an event with her later on, check the code, try and see what the "jump" scene label is for the dom route; play the sub scene, and when it's over, open the console with shift+O (you may need to activate it in ren'py) and type in the jump command to watch the dom scene. Just let the imagination stitch the two together
