Sex Open World e Youkoso! (セックスオープンワールドへようこそ！) Review

I.

I’m a 20-year-old virgin. The no-sex kind.

A friend invited me to a Christmas party and, beating his chest to pieces, swore he’d introduce me to all sorts of cute girls there.

But as a great virgin, how could I possibly hold court at such an event?

So I made a decisive choice!

I chickened out… again.

Looks like I’m spending Christmas alone again. I cursed this unfair world, and snow began to fall, white flecks everywhere, all of them narrating my miserable life.

Then I saw a dog in the middle of the road, and wouldn’t you know it, a big truck was coming.

Oh… what to do. The dog’s eyes looked so earnest, with a sort of untamed swagger in them. I decided to save it.

I rushed out and grabbed it.

Then the truck flew in. I died. The dog died too.

And so the life of a 20-year-old virgin ended.

II.

I opened my eyes to a big-titted girl in front of me.

Big Tits said I’d saved her life, that I was her savior.

Wait, no, wasn’t I dead? Is this heaven? Is the legend of the 72 Yui Aragakis real? Though why does Yui Aragaki have such huge tits?

Then I understood: I’d been isekai’d! Transported to another world, and apparently I’d become this world’s hero!

Apparently this Europe-looking other world has a legend: every 100 years a hero descends, and my arrival happened to land right on that time point, so I went and became the hero for absolutely no reason.

In this other world, the girl I saved took me back to her house, and I met all sorts of people—Big Tits, Big Tits’s older sister, the big-titted lady knight, the big-titted fox girl, the big-titted dark-skinned flower seller, the big-titted Japanese girl, and so on and so forth…

Every girl who heard I was the hero got all starry-eyed and started throwing themselves at me, which really didn’t sit right. I’m a virgin, so how’d I suddenly end up living the normie life?

Then the dog beside me started talking…

The one I’d sacrificed myself for.

That dog said its name was “Take-gyuu,” and with an untamed, slightly flexing air it told me it used to be a gamer and a priest, then got isekai’d into my world and turned into a dog, and after coming back here it couldn’t turn human again… blah blah blah…

Most importantly, “Take-gyuu” told me my standing in this world would be completely different from the original world—the exact opposite, even.

Meaning: however miserable I was in the old world, that’s how good I’d have it here.

I figured that out fast… the big-titted lady knight and the big-titted lady swordswoman started challenging me to duels.

The big-titted swordswoman told me:

“Everyone says you’re the legendary hero. I don’t buy it! Duel me!”

I reluctantly accepted, and before we even started, the big-titted swordswoman suddenly got a stomachache and declared me the winner…

“Taking care of your body is part of a duel too! I lose!”

So I won for no reason, and got acknowledged as the legendary hero for no reason.

III.

Having become the real hero, I was basically the center of attention in this country. Every girl came to bang me, all scrambling to “bear the hero’s child.” It was a real hassle, honestly—women coming to bang me every day, and I had to go along with it or it’d feel rude.

Just as I was living it up, I started having dreams.

Or rather, it felt like my soul was leaving my body, and I saw my first love from the original world…

I remember my first love died in the original world. I only kind of liked her, and before I could do much, she was gone.

First Love told me congratulations on finding a new self, that she was glad I was happy in the new world, and then she said bye.

That’s when it hit me: several women in this other world look a lot like my first love. Maybe I really do still like her.

Wait, I remember being a virgin… oh right, there wasn’t any banging, so yeah, still a virgin.

After I’d been dreaming a lot, that flexing dog Take-gyuu spoke up:

“Your soul leaving your body so often means you’ve become unstable in this world. If you don’t settle down here for good, you may only be able to go back to the original world.”

Holy shit, the original world? Go back to being a virgin loser? No way!

“So how do I settle down here for good?”

“Make babies! Go undocumented!”

Take-gyuu said, and handed me a chart of the menstrual cycles of every woman I’d banged (no idea how it got it), and so began my baby-making journey.

IV.

Women generally have a monthly cycle and an ovulation day. Bang a few days before ovulation and finish inside, and there’s a big chance of pregnancy.

But looking at this chart, I felt like an idiot.

Sure, some girls have a 4-day ovulation window and a 21-day cycle, but how the hell does someone have a 10-day ovulation window? Is she laying eggs nonstop? Are the differences between races really this huge?

So for that month, every day I carefully picked who to bang, finishing inside, making babies. Every time I had to cum twice, and the second load was always bigger than the first.

The goal was to get as many girls pregnant as possible, produce my descendants, and only then could I stay in this world.

But holy shit, making babies is not easy. At first I could keep up, but later I couldn’t. Think about it: banging every day, cumming twice a day, some girls would say they weren’t in the mood that day and wouldn’t let you bang, and the dumbest part is the calendar’s sometimes off, so you bang for nothing.

By the end I was about to die from cumming my life away, and I’d barely gotten 3 girls pregnant.

I guess I stayed, but only one woman was willing to accept my identity. Whatever—as long as I’m alive, there’s hope.

So I can keep letting loose and showing my stuff in this other world.

Sometimes I think it’s a bit of a shame. If I could’ve gotten every girl pregnant in one month, I’d surely have become a true hero.

Afterword.

Moonstone Cherry stopped making Imouto Tengoku and switched to this. The name is stupid; translated it’s Welcome to the Sex Open World!

Except the other world in this game isn’t open at all!

Overall it’s way worse than Imouto Tengoku. I don’t know why they had to draw all the heroines’ tits so huge—it doesn’t look good, it’s too fake, and it’s not even fappable.

The first half of the game has too much buildup, and it’s boring—so boring it looks like a “serious” game, with only those giant tits reminding me this is a nukige. The planner is Wu Lao Er, who did Sakura no Mori † Dreamers… which explains why there’s a weird childhood friend character the protagonist can’t bang. Next time, please hire someone who actually writes nukige, thanks!

Practicality is way down compared to Imouto Tengoku. The HCGs don’t have animation anymore, and the creampie close-ups are the same every time!

Yes, every time. Cum twice, the exact same twice, like copy-paste.

The game asks you to bang for 30 days straight late on, but since the HCGs are mostly copy-paste, it gets tiresome. And there’s that stupid “pregnancy quest,” which killed any desire to watch the banging.

Anyway…

Moonstone, hurry up and go make Imouto Tengoku 4. Stop making this nonsense. It says nukige but shoves in some normal content, and the normal content is full of holes. Sex Open World isn’t Open, the banging isn’t fappable, and the protagonist says he’s a virgin…

First time in another world and he lasts that long? A virgin? Who’s buying that!
