Mods are asleep, dumping final chapter.
I kinda feel bad for her. She only wanted to return home and now she only craves dick.
Here's looking forward to Nagashima's next bit tit H-Manga.
MC is retarded. A human species that is difficult to get pregnant are not genes that you want to pass on because these cavemen still have the same lifespan of a normal human and MC would only be spreading the genes for even lower fertility rates compared to the average modern human.
This is a genetic disaster waiting to happen.
As long as his kids don't start fucking each other I don't think it's such a big deal, there simply won't be enough new specimens introduced in the general world population to have that big of an impact.
Not really, realistically speaking what could he possibly do? Even if he were to whore his wife and offspring out with regular humans (which would be the fastest possible way to achieve what he's proposing) each new generation would get increasingly smaller odds of inherinting this undesired genetic trait, it's just unreasonable that such a small group of new specimens would have much effect on the esbalished genetic composition of modern humans, if anything we would be the ones genetically modifying them, not the reverse.
