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...
Well, Daniel's personality is what makes him stand out compared to the other protagonists, that's why Daniel is enjoyable to watch, even though he commits morally questionable acts. And it's not what happens with Uncle Peter, that his personality is to have the charisma of a rock. Well, no. A rock might have more personality. Simply put, Daniel is enjoyable to watch because of charisma and personality, not just his character model. Also as I said long ago, when one watches a porn comic one doesn't expect a story like the godfather, but it's nice to see a good backstory, so not being just meaningless sex. Also, if we go off on the tangent that other things are irrelevant, why aren't SN and TH stories as beloved as ID, after all, it is to have good porn, isn't it?
It's a lot of things that matter for a story to be good, not just its central axis and characterization, the personality of the various characters, plus the story are central things in themselves to make that happen.
