The game is in such an early stage, that closer to the end most of us will be astonished how naughty Sophia has become. Recall the recent jail event, that was her own volition and she surely was having fun.
I'm still in disbelief how many people don't trust L&P's writing skills. He's no Remark, Tolstoy or London. On the other hand, how many trully amazing VN's with the taboo/incest are out there? The Forbidden fruit is sweet and I can't imagine who wishes it more: Sophia or her offsprings.
I agree, I think L&P is doing a great job in developing the characters, their relationships and in building up Sophia's path. Sure it is slow but it is also part of the charm of this game, otherwise there would not be thousands of messages speculating on the evolution of the game (and complaining too,

).
And if I may add something on the jail event, two things stroke me about this event.
First, as you say, it is the first time in which she openly and willingly exposes herself without been pressured. Sure Larry asked her for plenty of stuff, but that final flash of the panties it's a bonus she gives and it's all hers. And she does it "having fun with it". Before this, she for sure took pleasure in exposing her cleavage to tease the boys in the morning and she came close with Sam with the areola. All the other times (if I'm not wrong) she was kind of pushed or forced to, even if she kinda like it in the end (e.g. braless in school, bikini show). So to me it's a kind a new development in her character that maybe can open to a more "easy going attitude".
The second thing is not really related to the character but to the narration. This is the first time we "see" Sophia lewd thoughts: before she had many naughty thoughts like being in the porno threesome she was watching, imagining being gangbanged by the students when Dylan explained her the meaning of MILF, imagining the cocks of the janitor, Zack's and Vicky's bf etc.
So that could be a new escamotage for the narrator to give more hot content without "messing" with the pace of the story.
For example, but just as an example, she could very well having again gangbang thoughts about the 3 kids she tutors if something happens during the lesson if e.g. some sort of nudity is involved or something like that (not a speculation, just an example!)
PS
it's true we had Sam dream, but it was his narration, not Sophia's imagination if i recall correctly
