I'm all for realistic or even ultra-realistic style. Hopefully in future we will have (with help from AI) more and more completely realistic art, even videos. The thing is, artist can make tits pretty big, and it's exciting, there's no need to make them almost "non-human", and the same goes for cocks - i mean , you can make it look like 20 cm big cock, and it's more than enough, there's no point in creating 25-30 cm long, and 20 cm girth monsters, that's just useless and stupid, and most of all not exciting. Excitement, especially in incest themed stories, must and should came from dialogues, plots, situations, accent on taboo, forbidden nature of this or that flirt, seduction, relationship. Mr Foxx for example made really incredibly realistic and believable mom/son couple in "Broken" comic, that's how it should be done.
