This webcomic is way too provocative for its overall story and premise, even by hentai standards. Even Gloria wasn't happy with it. Oh, and the writing of this porn manga is stupid and clichéd.
So, about her child(ren)? Deliberate (and even secret) refusal to draw children of an established parent (including MILFs) character is an red flag. It alarms me. I wanted to went my frustrations regarding the notorious trend of mothers/fathers/MILFS without children. This stupid trend, for me, is an contradiction and perversion of concepts of motherhood/fatherhood and related terminology. Sounds weird, but I was horribly worried about things getting worse. I personally had pretty bad experiences with this stuff. When it comes to Gloria's established motherhood (hence her aforementioned "MILF" status), I'm still waiting patiently.
