badtimetales calling this a porn game is rather reductive. The story elevates it way above that.
I am rather curious of how you'll handle the throuple. Because if the option exists, I will go for it. I can't give up Alex, but I'm not sure I could pry myself away from Isa. Yet, the guilt is starting to flare and it's (I know it) a joy killer. So, I am very curious about your way out of this conundrum.
You have several options, some more pleasant than others, maybe you'll even go for one I didn't even consider, that would make my day. It is so hard to be surprised anymore.
Peace
