Behold I am here to answer the important question, is this breast milk nonsense actually any good? Well it's complicated, judging it as a normal show, ignoring all the porn elements, I would say this is a 5-6 out of 10, bad in a kind of boring way. Worst part is it starts off somewhat decent, but the second half takes a steep dive into boring incoherence, characters break down, power mechanics break down, things start to happen randomly etc. Even the fan service quality is significantly worse after ep13, so it might be a good idea to pretend 13 is the final episode, it's not a bad way to watch it.

Instead this show is exceptionally well done in what you pervs really are here for, the "plot" of course. These are some of the best plot in anime, anatomically detailed, big plots, small plots, and everything in between. It also strikes that perfect balance between size and sense of weight. Bad shows tend to have big plots that feel weightless like balloons, but if you go too realistic with the weights, shape tends to suffer and become too realistic, less attractive. This show gets it perfectly balanced, like all things should be.

Other than this breast milk gimmick, it also has plenty of other services so the variety is quite enjoyable. Not only pushing the limits of what could be shown with the plots, it also pushes the limits of what could be shown or implied, down below.

I do have one very specific complaint about the naughty stuff, usually they happen in private, you know just the bad guy and the victim, and her friends. But there is an episode where a character gets, taken advantage of, in public in front of all her classmates, which I think crosses the line, not only in terms of viewing comfort, it also breaks immersion because the next day, that character just goes back to class like nothing happened, and none of the classmates have any problems either, which just screams to me, "that's not how sexual violence works".

The characters themselves again I would say before episodes 13, are actually half decent, they have believable motivations (at least when not in a fan service scene) and feelings. They make some progress with character development even, people learn things and think about what they're doing. Unfortunately the ending is so bad it kind of invalidates these previous developments. Same thing goes with the story itself, at first it looks like something coherent is going on, but it just breaks apart. Show starts introducing a bunch of irrelevant, uninteresting and unnecessary characters, only one of which has boobs, that tells you how unnecessary they are.

The finally fight was almost bad enough to be good again, the bad guy can catch your sword with his cleavage squeeze, would you believe that? But that's probably the best moment, the rest are just boring fighting that don't make any sense and don't mean anything for the characters.

Bonus point for the ultimate love for plot in Anime. Note my echo show rubric has different criteria than normal shows, it emphasizes visual quality and eroticism rather than story arcs or themes and messages.
