I don't even particularly care for spanking and I enjoyed this. The domination and humiliation is too good! Only thing I disliked is Kana's overt plot armor - knowing she is immune to turnabout robs some of the erotic tension from many scenes.
Ahaha, excellent. Assuming a 7 day week, I actually super like the decision to make the first 3 or so days the 'Kana dominates everyone' show. So really I'm only complaining because I can't play the next 4 days yet XD
