Blud, what are you waffling about? A majority of Sileo is porn scenes and their setup. The worldbuilding itself is the way it is because it’s a gay furry romance story where everyone is gay. Sex scenes are literally major plot points in most arcs!
By contrast Temptation’s Ballad also has a LOT of “porn leaning” elements, but the story itself doesn’t revolve around that. Not that it has no influence on the plot or relevance to some themes, but it’s not nearly as core to the story as it is in Sileo. I’d say it’s mostly like an ever present aesthetic choice.
But like, Temptation’s Ballad IS still very sexual? Cole’s promiscuity (and half the supporting cast’s tbh), the mercenary company, the multiple sex scenes? It’s not just “mere mentions of sexual activity”, what are you talking about? Half the cast can barely keep it in their pant half the time, and that’s if they even wear those!
