It's because it's hentai. You're reading porn and expecting it to be decently written lmao
I'm not expecting anything, personally, what I'm upset about is that is not moving on. Even porn is no good if it is so repetitive you are too annoyed to fap. Porn isn't held to as high of a standard but there is god vs bad porn out there that has little to nothing to do with personal kinks/opinions.
I hate the odb kink personally, and I do complain because I'm totally allowed to do so, but I gave it only 1 star because we're on ch. 25 and there has been no progression whatsoever. P w/o p is fine, but then make it a oneshot. This is clearly intended to be a pwp so it should have progression. The language being horrible just furthers that it's badly written. It could be on purpose as a troll, sure, but that's a lot of time out of ones day to make such stuff, for it to just be a prank.
Author is definitely trolling. Because there's no way one can write this kind of ridiculous dialog and be serious about it. They are like "take in my manhood at once, my sex slave commander. As for I will gladly bless you with my baby seed." This must be dark comedy, satire, yaoi parody, rage bait all at once. But looking at it that way it is kinda funny because it's so incredibly absurd. It's so exaggerated
