Princess of the Void

★ 4.9

dukerino

An alien abduction romance. Updates Mondays, Wednesdays, and Fridays.
Grant has a tolerance for boredom. Late shift in a middle-of-nowhere facility? Sign him up. If the money's good, he'll happily take the peace and quiet of a long night watching an empty cell.
And then he meets Subject B-31. Blue, beautiful, and completely inhuman. Her captors call her Batty, thanks to her big ears and the way she hangs upside down by her tail.
He's told not to talk to her. He's told to think of her as a test subject, not a person. He's told to cash his checks and live his humble life. He's told to ignore the sorrow on her face and the desperation in her crimson eyes. Maybe he should have listened. When he finally busts her out, the rescue isn't a rescue at all: it's an abduction.

Batty is Princess Sykora, of the tyrannical Taiikari Empire. She commands the Black Pike, a massive voidship on the imperial frontier. Grant must learn a new life, in a firmament filled with ambitious nobles, deadly rivals, and the sinister smiles of the Taiikari Imperial Court. And he'll have to learn fast.

Because when the Princess of the Void looks at Grant, she doesn't just see a savior—she sees a husband.
And she isn't asking.

Monster Breeder

★ 4.5

Ladonyx

Alex is a normal girl in a post-apocalyptic world of monsters. The remaining pockets of humanity now coexist with tamed creatures that defend their towns from existential threats beyond the edge of the map.
Then a Mark appears on Alex after a unique encounter. Now she can transform herself using monster essence! But the more she changes, the further from human she drifts.
Join Alex as she becomes stronger, assembles her allies, and eventually founds a clan to fight for dominance of the region!
It takes a monster to fight a monster, and someone has to breed them.

Slightly interactive with periodic CYOA votes.

This is an obvious parody with a semi-serious tone, lots of monster sex, a futanari protagonist, and a growing harem of monsters (mostly girls with a few exceptions).

WARNING, Alex is bisexual and there will be both male and female monster species. If any of that isn’t your thing, move along.

All characters are +18 including the monsters, who are sapient with the ability to consent. Some scenes have villains committing acts of sexual violence, but there will be no non-consensual sex scenes with the protagonist.

Chapters will be tagged by Kink in the Spoiler at the start.
Bonus Chapters have extra-kinky material segregated from the plot to make them skippable if they're not your thing.

Updates will be sporadic at best with many hiatuses.

I appreciate your support!

Cambrian’s Emporium of Everything (Multiple Settings)

★ 4.5

Cambrian

Summary: I have a lot of one-shots and stories that are only a handful of chapters which it doesn't really make sense to post one at a time to a website like this. So my aim is to post them all in one spot under this umbrella fic. There will be a bit of everything in here, though each story will be appropriately marked with its setting and themes.

(Much of this content will have originally been written years ago until I catch up to my other websites)

Regressor: Harem Building Lunatic

★ 4.6

Hedgasm

In his last life, Mizuhara Souta wasted everything. His youth, his chances, the girls who loved him.
Now reborn into his youth, he won’t make the same mistake twice.

To everyone watching, it looks like the start of a normal romcom: a childhood friend walking with him to school, a kind mother fussing over him like family, and a new transfer student bound to stir things up. Cherry blossoms, school trips, festivals. Sweet, wholesome, ordinary.

But Souta remembers his regrets. This time he’ll claim Kotoha, the innocent childhood friend who’s already learning to melt under his touch. He’ll reach for Hikari, her gentle mother hiding forbidden desires. He’ll welcome Hiyori, the late arrival destined to complete the picture.

On the surface, it’s love and laughter. Underneath, it’s oyakodon, obedience, and the purest harem imaginable.

THE CURSED GAMER

★ 4.0

Master4thWall

[R-18, Mature Element Warning!] [Multiverse!]

A young man with a questionable job dies, eaten by a shark. To his surprise, afterlife was a spinning roulette that decided his next world and powers, with an annoyed Goddess supervising the process.

The Gamer System welcomes him with open arms, and he shivers in the endless potential it holds. If used right, he knew The Gamer could step beyond even Godhood. Beyond God.

Out of desperation, that was exactly what his goal became. The Goddess was a snitch, and now she and her fellow Gods wanted him dead. What, and why?

In the end, [Soul 799], soon to be renamed as [Neji Hado], becomes a Cursed Soul.

I Raised The Heroine Wrong!

★ 4.4

Kalliel

I got a cute heroine in a dating sim as my little sister. So, I raised her as preciously as I could. I gave her sisterly love, expensive elixirs, gave her endgame equipment, relics—you name it.

''Big sis... you must never leave my side. I will not allow it.''

Until one day, she turned yandere on me, and her eyes that were looking at me seemed quite different. On top of already being surrounded by crazy women...

Isn't this too much?

*****
What to expect:
- No incest.
- Protagonist (Female) x Love interests (Futa).
- Pure harem, not polyamory.

Release: 3~5 chapters/week.
