I don't think so. I think lot of these kinds of mangas greatest strenghts is the slow tease. Sure, it could be a little bit more of it, but if this manga would be porn it would be boring, because the whole plot is all about, when they will gonna do the thing.
I mean, just read into those long hentai mangas and webtoons, they just have hundreds of characters introduces to have some boring filler sex at every chapter that it becomes very boring very early.
I think you misunderstood me. "Porn" doesn't specifically mean "Regular, hardcore sex". I mean to say that the author is clearly desperate to have them do explicit, sexual things right on screen, and then hide it all. I assume you just saw my post, then replied instantly, so I'll repeat myself:
The first chapter featured her literally recording him jerking off. Then there was the thing at the well, off the top of my head. I feel like if a dick is out, and being used, I should be able to see it without several layers of people and/or sheets in the way. Not that I'm eager to see a guy jerking off, but by the time you're doing sex stuff on screen, you clearly want to make porn, and I encourage you to do it instead of blueballing us both like this.
My point isn't that this should be a 100+ chapter long orgy, but rather that if the author really wants to have them touching, licking, jerking, and sucking right where we can see it, he can do us a favor and not hide it all behind the edges of the panels, or sheets, or people ( like Chapter 1). For example: MC's gotten at least three full handjobs right on screen, and all we've gotten are a handful of panels where his tent gets worked. You could almost forgive the one with Akari, since the goal wasn't specifically to get him off, but then Kaguya straight up says "Show me that dick", jerks him off, and all we see is the outline of her hand under the sheets, since she, for some reason, didn't even bother moving the sheets off him.
See what I'm getting at? Either
do the scene, or imply it. This is the worst of both worlds.
