Hanako: naturally, she'd want to do it with the lights off the first time. hopefully Hisao's okay with that. but I kind of get the impression that she's not used to being touched, and not used to things actually feeling good for her, so once she actually gets going and remembers what it's like to feel good, she'd probably be pretty damn into it. I don't know if it'd go to the extreme of her wanting to have sex all the time and not caring if people see her (long road from recluse to exhibitionist), but I think she'd get less shy about showing herself to Hisao and probably initiate sex after a while. don't know if she'd be all that kinky, but you know what they say about the quiet ones.
Shizune: not much noise but I'd bet lots of heavy breathing.

Emi: seems like she'd be good with either top or bottom, but she'd be ready again about two minutes after you were done. most likely to give Hisao a heart attack, eh? she'd probably be a lot of fun, though, making cute noises and all that. finding compatible positions would be interesting - sex swing, anyone? also seems like she'd be totally okay with getting herself off while she waits for you to get hard again, which is one of those "everybody wins" kind of things.
Rin: I know, I know, "epic footjob." not saying that it wouldn't happen, but it's not my thing. I have no idea what sex with her would actually be like, 'cause it'd be hard enough to figure if she was propositioning you or just on another of her tangents. gotta say, though: best position with Rin would be her sitting in your lap, facing you, her legs wrapped around you.
...what?
Lilly: gotta admit, I'm not really looking forward to the Lilly h-scenes, as she seems to prim and proper to be all that much fun in bed. although she'd probably not be self-conscious or embarrassed, since she can't see you and probably doesn't mind that you can see her, and there'd be lots of touching so she could see what your body was like and she'd want you to touch her too and maybe she'd ask you to put on a blindfold or something so it'd be nothing but touching and voices and breathing and oh fuck looking forward to the Lilly h-scenes now liekwhoa.
...so, what're everyone else's thoughts on this?
