As a model for sure compared to other sons/boys, personality??... He doesn't respect his mother at all. If he had, he would never had sex with his own mother. At the very beginning of that sexual relationship, some situations seemed almost like rape. Considering that everything is allowed in porn comics, personality and character are absolutely irrelevant. Only sex is important, the rest are platitudes. BTW there is nothing what make him cum unless he eventually stick it in the pussy... Come on. How many time and in how many porn comics we must see it to don't see it anymore. A little originality please...
Her son is as aggressive as he needs to be to push their sexual relationship forward. The formula Daval is applying in this narrative is actually common. And he's not "raping" her or anything like it. Sure, he doesn't always respect her boundaries, but we would expect that such boundaries would be informal among family members. In Chapter Two, if I remember, he presses his face against her bosom, hugs her tightly, and palms her butt. She seems unbothered by this. Now compare that to chapter eight when a stranger palms her--her rejection is immediate, even before her son "rushes to the rescue." What's great about her son's character is that it's in stark contrast to her personality. Daval is obviously trying to portray her as a moral, demure, upstanding wife and mother (though I would say that her dialogue specifically can use some work, i.e. her 18-year old like "cussing.") The point of their dynamic is that she's set in her outward denial of her being physically attracted to her son, and her son is portrayed to be a bit more than just sexually attached to her, especially in his jealousy toward his father, his frequent attempts to kiss her, and his physically accosting the stranger who attempted to harass his mother. Daniel's likeable because he's aggressive toward his modest mother. While not "original," there are some tropes that just work regardless of how many times they're reused.
