As with the first one, this one went through literal translation, figurative translation, and one just to smooth out the prose. I really love Sensei's work. There's a sweetness and a kindness and a realness to the interactions that's just a delight to work on.
I was surprised to see he managed to get Mitsuru-san to do pretty much all the things Choco fantasized about in the first part (although in different ways). And I think he put a nice little twist on her masochism. Most of the time an M-person will act like they're being forced into it. But Mitsuru-san is moving into it and trying everything with her eyes wide open. Her willingness to try new things is quite endearing. And her fearlessness makes her incredibly sexy.
