It's not often I find a story (manga or otherwise) that's equal parts story and sex. Usually when I see something that tries to balance it, it ends up falling on it's face by leaning too far on one side or the other, but this actually manages to strike the perfect balance between the two. Good job Mira.
Let's face it. Kuro's demeanor when it comes to sex and lewd stuff will vary depending on who it is.
Nemo: Deadpan and silently judging her trepidation
Yuri: VANILLA AS FUCK
Katou: Nervous about screwing up and making her mad
Ucchi: Scared and confused (because let's face it Ucchi will be sending mixed signals the whole time)
Miho is a closet sadist. I've seen this headcanon in other doujins, but now I am completely convinced. I can't be the only one who sees it! Her favorite show is about a hero bear getting the shit kicked out of him before finally saving the day!
