The Otaku in 10,000 B.C. - Volume 1

I enjoyed the story a lot! The artist has made an instant classic with this Isekai venture into Prehistoric times! The artwork was phenomenal my only complaint is that this work has uncensored art mostly the male genitalia is whiteout that makes it look like a light saber so if you don’t want any censored whiteout art on your purchases I suggest giving this a pass and look elsewhere. Overall, it’s a solid volume and will look into the next volume next.

Story is kinda mindless but it's fine you aren't reading for the story. The girls designs are very thin with big breasts. If that's your type then definitely pick this up. Lots of breast milk play. The whiteout censoring is annoying but it isn't *that* bad compared to some other whited out series on here.

I've read this online before and had to have a physical copy to add to my collection. I love the story and the art. All the ladies are beautiful.

The art was really good, the girls beautiful and I liked the story.

I had my reservations due to the “whiteout” in this book/series, but it really didn’t hold back the story. Well done indeed. Gotta get Volume 2!!!

According to the notes at the end, this was inspired by the 1966 movie One Million Years. I think Nagashima Chousuke did a great job! He made the concept work. He made it interesting. I really loved how he mentioned the actress was still beautiful in 1994. He really appreciates the female figure. :)

The female characters are very beautiful. The breasts are huge and very soft. I love the detail to their softness especially when grabbed. If you like breasts, lactation, sweat, blushing, surprised/embarrassed faces, slender bodies, and long hair, you will LOVE this. You will not see detail to genitalia; you'll see labia (majora) but no clits. The penises are censored white. Other than that, this is still worth checking out.

As for the main character... He's ok...he is a teeny bit annoying at times, but BEHOLD: HISTORY'S FIRST SNUU SNUU FROM THE FRONT! xD

I honestly didn't know what to expect with this one and as goofy as some parts I quite enjoyed it!

Nagashima really knows how to write an interesting and captivating story.

This is my favorite of the 3 in the series. The beginning of the story, a wonderful fantasy, intros of the best girls, and this one has the best tiddy squeezing and milk squirting.

Interesting concept but main character kinda useless on anything. But want to see to the end.

Definitely a great read! The women look exotic and all you can ask for from a prehistoric hottie. Main character is kind of annoying, but honestly you can look past it.

Really hot women and a story arch out of this world. The imagination is just...muah. I love it!

I love the story, no matter how silly. Women are drawn beautifully, and the sex scenes are quite nice!

This was my first time encountering a whiteout tag and I didn't realize what it meant until I started reading. What a bummer. I can see from other reviews that it doesn't bother everyone, but it took a big bite out of the erotica quotient for me.

Other than that, it was a pleasant diversion. The plot develops a little slowly, the protagonist is a stone-cold loser, but the artwork is well-drawn and who doesn't love busty cavegirls? I wanted to like it more, but this was more disappointment than delighted discovery. I bought all three volumes, so here's hoping it gets better!

Now for a Hentai I quite liked this series, but the story is still inadequate. Again, the art and boobs are amazing.

If you like big tits and don't have an aversion to the tags, you can buy this without question. The whiteout tag and lactation tag are perhaps the two most noticeable outside of the huge boobs. Of the two of those, the whiteout tag has been used in different manners on different works. In this particular work, it means the genitals are literally whited out. Sex still is happening and you can see the whited out penetration at times and in all honestly, it doesn't really detract from this work because of the main focus being in the story and the bodacious bodies.

This is Fakku's first isekai series, and it's about a nerdy type guy that really likes an anime about prehistoric moe cave girls that gets sent back in time. He is much weaker than the prehistoric people at the time, but compensates with that with his knowledge of sex. Apparently knowing more than one position back then makes you a massive hit with the ladies so there is plenty of opportunities for "boinking" as they put it. I personally have not read all three of these volumes at the time of this review but as a standalone volume I do enjoy this one.

I'll say it once more, if you like big tits you need to buy this work.

This is the first volume of Nagashima Chousuke's fairly well-known prehistoric sci-fi series. It follows the story of an otaku who somehow gets pulled into the past where he encounters a tribes of prehistoric cavemen (and more importantly, cavewomen). As you can see from the sample art the women have figures and insanely huge boobs that aren't remotely realistic in _any_ era, but lets be serious here, you're not buying this because you're looking for an accurate depiction of humans from twelve thousand years ago now, are you?

In the first volume most of the stories involve the protagonist Ota having sex with the tribeswomen he encounters, where he gets to pit all of his modern sex techniques against their primitive and simplistic boinking techniques. However, near the end the plot starts to develop more as there are hints of how Ota might be able to return to his own time.

Now, the big disappointment is the fact that the book is censored: it uses the whiteout technique to censor the genitals. This isn't FAKKU's fault as they did what they could with the source material they had to work with, and they did what they could to minimize it, but at the end of the day it's still hurts in comparison to most of the work published here. That said it's hardly a dealbreaker, as the story is still amusing and there's more to hentai than raw penis and vulva art.

Favourite book so far!

I feel like people got suckered because  it is not uncensored for a site that does legally.

This book is pretty damn good, it's got a bit of comedy and the art style is amazing. Prehistoric, interesting.

Can't†‹ wait†‹ for the†‹ second volume.
I wish there weren't any whiteout though.

Why isn't this uncensored :(

When are the download links going to be available? They should be out now but I don't see them anywhere.

I get to but and read a good story? Alright! Sounds good!

Boinking has never been better

Yoo what time I've been waiting. Since this morning

Loved this series enough to commission its translation. So glad to see this title get picked up by Fakku. Now I get to enjoy it uncensored!

I never thought I would see THIS here! I need a physical copy of this! Thanks for the great news!

Instabuy! hope they release "Girls Must Die" & "Yareru Appli".

100% sure there is NTR on here, so be warned! But the artwork for this book is amazing so it's worth it :)

Oh Hell yes! Been waiting for this one. Instabuy!!!

I feel like I’ve been waiting since 10,000 BC for this to be published! Boom! Love it!

Volume 1... which means this'll be one prehistoric wild ride.

Bet you ten bucks we're all descendant of this guy

Whoa. Prehistoric snuu snuu
