Yeah ngl I kinda skimmed the dialogue this chapter because it was obviously cringy, but the intent behind it wasn't bad.
Seriously though fuck that guy. It's all cool to want to fuck a ton of women, but having an obsession with cumming inside to claim them is some real creep bullshit. Agawa definitely shouldn't do anything with him anymore.
I can actually kinda respect how the MC is progressing, even as annoying as he can be. Like he's a total nervous wreck in general who never even held hands with a girl, and all of a sudden he's railing the fuck out of a girl who treats sex like breathing. It really does make sense that he'd be absolutely fucking up 24/7. The constant open mouth OMG face is a bit much visually, but I can appreciate how he's having to seriously wrestle with a totally weird situation.
And she actually got mad at him for putting it in raw when she said not to, unlike 99% of hentai where the girl just goes "Oh, you put it in raw? Guess I want babies now." For a girl who fucks at least one dude a day, she takes her own consent and safety seriously which I like. It makes sense. Why would a girl who LOVES sex risk getting pregnant and limiting her options?
