Definitely progressing too fast. This is porn territory at this point. And the violent one I ain't comfortable with, too.
The first 2 chapters were odd but funny, chap 3 was disturbing, but in a more digestible way...
This series went from "taking coocoo vengeance om my dumb bully", to: "look at my hot lover and my foot fetish, as I get wet beating her up"
P.S: I want to clarify my thoughts a bit about this one, in case anyone even cares:
It would be more apt to say that, I don't mind "it becoming porn", but I do mind that: "it becomes porn I don't appreciate".
At the top levels of "fetishes I cannot respect" is "beating up my lover". And this chapter just glorified beating up someone, and leaving them with "love marks". That's just messed up.
NTR is also in bad taste, but at least it just comes across as "aiight this is not for me, gg" -- but the whole "let me leave love marks on you" shit? That's on a deeper level of uncomfortable.
If this story will just keep devolving into: "what more messed up shit can I make blondie here do / inflict on her?", It'd obviously not be for me. I don't need a second Metamorphosis.
