As someone who read mainly works made by women it's not suprising at all lmao , at lot of women Artist can be very gooner for women as well ( i 'm one of them) . Some most atrocious nsfw are made by women lmao. Anyways her boobs and butt were always that big , it's just depend of the clothes she is wearing , as for her waist is normal it's just depend on the angle, but if you carefully she got a cute Tummy rolls and little belly ( her proportion are not that crazy lol)
If you saw how some women artist drawn women in pornhwa and hentai douji it's not really that suprising lmao, a woman artist ≠ having a pure vision of women Lmao , even at lot of women sexualise themselves very much, so it's not always a man thing. Personally her body is resonable, go look at pornhwan women you will see that artist is still reasonable with her , she even got a tummy, her waist just looked off because there because of the angle and that big ass shirt lmao

i still can’t get over how her waist gets thinner and her hips and bust get bigger every chapter it’s actually killing me like what
