well, this is just smut through and through. I remember reading the hentai manga adaptation a while back and it was pretty good. The premise is that the MC is a chronic masturbator that gets isekai'd by the hero party and the girls power up by drinking his cum, so, naturally, he has to give them a lot of it. The girls are the typical heroine archetypes (tsundere, deredere, and so on) and they have enough of a distinct personality for this type of novel at least. This actually works... more>> in favor of the s*x scenes as it gives the illusion of them being not just blow-up dolls but characters in their own right, which in my opinion is hotter.

All in all, it's p*rn alright. You don't read it for the plot though at least the characters are memorable enough. <<less

Although this can't be the best, neither one of the best ero novels but overall it was really good. Most of the chapters delivered long detailed 'ero ero' scenes which is pretty amazing when it is suppose to be he*tai novel (ahem) where most of the authors miss to deliver. The three adventurer girls were pretty hot (*////*) especially Mila was my best but she didn't get any alone time (pretty sad). The wierd thing the author forgot to write is the detail of the story, weirdly enough, male characters... more>> were not mentioned any of the volume except when Filia was on the cliff with Tomoki, the characters were described vaguely. I imagine there were males down there but it doesn't make a difference. He should create makes characters as well but how would he know. Anyways, waiting for volume 3. I couldn't read volume 5 and 6 in the Manga and the animation covered only till 2nd volume. So I'm expecting the novel to complete the series. <<less
