The focus on her cleavage this chapter was kind of taking my attention away and I had to read it a couple of times.
Though the kid didn't care about her cleavage, he just wanted cookies.
That's the thing, isn't it?
If one gets one's mind out of the gutter and drop the shota fetish, unlike some here, the story is about a ded-hard warrior who adopts a child while being pretty much unsuited for it.
And struggles through it while developing Motherly Feelings for the kid. Another challenge she's hopelessly unprepared for. Different kind of battlefield, and all that.
Especially with the kid attaching himself to her as a
mother, or at least family. As kids do.
Quite a lot of the boob shots are drawn from the perspective, and height, of the child.
It's entirely possible to see this in a sexual context, all that self-insertion stuff with a gutter-mind, but in my opinion that detracts from the story, especially since the child himself isn't interested in that at all.
As this chapter shows, Cookies are what's important. To the point of obsession and breaking the rules. As kids do...
There is no shota, there's just a child seeking safety, and a hapless warrior trying to provide it.
