Haha looks like im in the minority here. I for one hope we will see Asunas dad/ Kyokous husband. Just because it would be so devastating for him to see his wife and his daughter getting the time of their life by another mans dick.
Showing short flashbacks of him and his beloved when they were happy, then fading to their faces full of lust and depravity. then him falling to his knees and asking himself where things went wrong... *shivering from excitement*
Ops, looks like my inner ntr side showed itself again, my bad my bad.
Anyways i highly doubt that to happen for this game. So far the ntr were really mild so i cant imagine Fujino-Sensei going down that depraved route..
