I'm playing altruistic path but Aurora's relationship ended up being the hottest to me, I wish there was no path requirement to keep pursuing her because behind her bitchy façade, deep down she is sensible (how she describes her paintings) and sweet (how she enjoys hugging and sleeping together), unlike actual bitches who are downright and full time bitches (like Andrea, who isn't sensible nor sweet). Aurora fits so much better with an altruistic man who isn't a pussy, rather than a cold and selfish one...
I find Elsa model one of the hottest ever but her relationship jumped from almost 0% to 100% too fast for me, I think I recall you get to fuck her before even kissing her first lol and that's for the altruistic path, where Aurora is off limits but she on the other hand had a progressive romantic development.
I don't know if MisterMaya changed his idea on strict separated paths, I remember in the early prologue you are told you had to choose and that he would intentionally close it so no neutral path was possible. But I had to fuck Aurora many more times as an altruistic than you could expect possible.
