Hi,
Why not? First; it is just my own opinions, second; my points can be helpful, because, if those are points which others also mentioned, this can push people in the right direction.
I apologize for my wording, looks harsh afterwards. But the essence should be as following.
1. It needs proofreading or at least a decent translation. Writing feels unnatural. Capital letters are also missed at the start of the sentence, thoughts could also made look different from the normal spoken text.
2. For me it is too slow burn with lewd content - it should not say at the beginning the family is so free - it caused for me false expectations, in such a free family I expect at least less clothes in the household, and already affection showing between them, it is the step mother (or did I misread?), therefore not blood related. It just felt like you are already stepping into a lewd family. In hindsight, I really don't know why this is emphasized, as those look like normal rules...
3. Yea, the MC, also only my opinion, but he looks like a little mid-aged man. But 3D Modeler are rarely concentrating on good looking male models. I just find him not handsome, like the writing is trying to.
Regards
