I wish the translator or whoever put more effort to avoiding repeating certain phrases. My exposure to wicks and being taken from behind has increased a thousandfold from reading Fakku releases and it takes me out of it when I'm reminded that I'm just reading text some guy translated instead of a story.
Upon the realization that Satou has a big dick the other girls will try to get a taste of him so that Saki has no other choice but to make clear that he belongs to her and make sure that he has only eyes for her by fucking his brains out...
Well, it sort of seemed like it was getting pretty sweet around the middle to the end where she started to enjoy herself...And then by the ending it's back to their master servant kind of relationship.
I was hoping for it to develop past that, but I guess they're both pretty happy with the current state so nothing much to say, I guess. It'll probably eventually happen on it's own. (Wish I could see it, though)
