Although her actual H-scene is well lit, it's also a odd case.
I drew the conclusion during this fic that assumptions based on Hanako's sole in-game H-scene might not necessarily apply during further sexual contact. Hanako's sole aim during that first time was keeping Hisao close to her. Avoiding awkwardness or pain simply wasn't a priority for her at the time. It'd be a lot more important for her to ease up during intimacy in the actual relationship, since enjoyment would be the whole point of the act. Hence, the focus on keeping the lights dimmed or off altogether.
Although I wonder if it might have been a little easier if Hanako had taken her tights off. That just doesn't look comfortable to me. Of course there is the emotional awkwardness, but that's been discussed elsewhere.
It would have been somewhat easier, but it wouldn't have made a world of difference. Intercourse, especially at first, tends to be painful if the girl isn't at ease (even if the hymen wasn't intact anymore) due to the tensing of the vaginal muscules. There's no way Hanako would have been comfortable enough to enjoy it, no matter how much foreplay. (her body was already aroused at that time, but her mind most certainly wasn't.
Now about the sex scenes in this fic. The thing I find interesting is that they are from Hanako's POV. I wonder what was going through Hisao's head? Well I like to think that when Hanako offered to give him a hand it was "YES YES A THOUSAND TIMES YES!" But more likely he would have had some concern he might be pushing into it, and deciding that he has to trust that if she says she wants to do something, she is, and will tell him if she's not.
There were many scenes that had me wondering whose perspective was most suitable, but as a rule I felt that if I was undecided, Hanako got the benefit of the doubt. That's because Hisao has less difficulty voicing his thoughts than Hanako, so I can simply make him say what's on his mind without it appearing out of character and pared with Hanako's thoughts the reader can still get an impression of what both are thinking. Of course, the inverse is also true...there's no Hanako-perspective during the hospital scenes later in the story because it was convenient for me to keep Hanako's exact thoughts hidden from the reader for a while.
What I imagined going through Hisao's head at least some of the time was along the lines of "How can I keep things completely consentual?". Well, their first time was consentual, but only for messed-up reasons. I figured Hisao felt pretty bad about that first time, having failed to see through Hanako's reasons for initiating it and because of that he'd be kind of wary of moving things too quickly, yet at the same time he'd want to show Hanako he acknowledges her as an equal sexual partner he was attracted to and not as a fragile girl made of glass. What Hisao thought when Hanako made her offer was mostly pleasant surprise.
Finally I kinda see Hanako as being the sort to cuddle afterwards. Not counsously, but rather after she falls asleep she'd press her unscarred side up against her lover. Nothing really to base it on, she just looks like the sort to me.
That's probably primarily due to Hanako giving off truckloads of Moe-vibe. Moeblobs are pretty much defined by their tendency to make people want to hug them. That said, one of the reasons I made her a bit of a snugglebunny was due to the fact that the hormone Oxytocin (also known as the cuddling hormone or love hormone, which is released into the brain during cuddling) acts as a natural suppressor to anxiety and PTSD-related symptoms and puts someone in more of a trusting mood. (trust isn't always Hanako's strong suit) In other words, she gains more advantage from cuddling than the average person...it diminishes the pangs of distrust she feels from time to time, relieves her anxiety and leaves her less prone to nightmares. I played with the thought of Takawa mentioning this tidbit to Hisao, but couldn't really find a good opportunity for her to mention it, so I left it out. Use it as a base reason if you please though.
It must do wonders for her self-esteem to be able to take charge of pleasing Hisao and controlling when and how they go.
Hanako taking the initiative was mostly due to Hisao somewhat pushing her into that role and not because she was comfortable with it...to him it was the best way to ensure that whatever happened would be something she consented to. Still, pleasing him was something she enjoyed. Hisao, however, was wary that her focussing on him too much might become a habit, so he was rather quick to suggest Hanako join him in the receiving role.
True but then she wouldn't be the Hanako we know and love. Then again, I like the idea of a more confident Hanako, as long as she still has that occasional stutter.
I don't think Hanako will ever be extremely assertive. Her way of being confident will probably just focus on being at ease with herself and the people directly around her.
