You miss the point of visual story-telling entirely. In any visual medium, what is drawn and what is not drawn serves to support the context/focus that the work is trying to build.
Ignoring the fact that the molestation portrayed already is pretty shocking in and of itself, by omitting some of the stuff that's implied but drawing her reactions to it, how she's dealing with it, etc..., it shows that we're not supposed to be focusing on the act itself but the repercussions of the act and how it affects the whole situation. This is visual story-telling 101.
Basically, this manga is trying to be an honest portrayal of the affects of child molestation, not a fucking porn comic, so they're not gonna show the act because there's no fucking reason to do so. Not to mention that this is based on a real experience so I doubt the author would want to graphically portray their molestation even more than they already have, the author's already gone above and beyond the call of duty in that regard. We don't need weirdos like you who are just looking to jack off coming here and completely dismissing a genuinely emotionally tough work.
