Great demo, took the two routes to try and the dom seems the most natural with the main plot and it gives the better rewards too.
The art's awesome, the dialogues and text are good too. The music is very generic, not sure if that's the best (or even a good) choice, honestly. The audio clip at near the end of the dom route seemed a bit lackluster, I expected the wife getting progressively more excited and hearing the dude's heavier and faster breathing, along with some whispered reinforcements and complements, but that's just me.
All in all, following as I'm interested in what will come of this project of yours.
