Dude's refractory period must be similar to the cool down on his skill, cos im not young, and I would have... attention issues in that specific hot tub; particularly with girls undressing me and bein' all nekkid.
BUT! But, but, but...
Even as a teenager, mixed company bathing is easy to, shall we say, "not show;" it's surprising how getting naked in water in a mixed group is just... being in water naked, and not sexy at all.
The problem only really arises when conversation lapses, or when alcohol, or other such naturally derived aperitif, are involved; then, things get... well,
fun, honestly!
So, the loli dragon is coming, wonder how they’ll deal with all the lolis and, specially, with all the r18 stuff. Given it has the suggestive tag not the erotica, I’m guessing they’ll keep on censoring body parts and when he finally starts doing it with his harem they’ll just suggest the act, and cut straight to the result. Or, maybe, they’ll turn this from an r18 story to a r15 and remove all the seggs from the plot, find it hard to believe, given how central to the entire plot his D is.
I find, a lot of times, that many of these light novels that get turned into manga tell an entirely different story. I gather that this one had a whole lotta bangin' in the LN, but this may exclude it entirely.
Who knows if that's the case here, but my money is on trite, trope-filled travails, trying to attract travelers and some open-world-style land improvement/development.
Just like the last 18 chapters.
