Xeno that commits
Anatomy, senses, mating customs — invented properly in the story bible and used consistently, in and out of bed.
Sci-fi erotica on demand · 18+
You've read every alien-warlord book KU has. Design the next species yourself.
The ice-planet formula proved the appetite; the flood of clones wore it out. You want the xeno-romance where the biology is inventive, the culture clash is real and the heat is explicit and specific — not chapter-three abduction number two hundred. Describe the species, the dynamic and the heat, and read it tonight.

Why generate instead of scroll
The subgenre found its formula and stopped inventing.
You keep buying because the premise category is right, and DNFing because the execution is the same book again. Write the variation you've been waiting for in two sentences.
A plot in orbit
War, trade, first contact, survival — real SF stakes that the romance complicates instead of replacing.
Heat, specified
Explicit scenes built around the dynamics you name — heat cycles, fated bonds, size difference — inside your limits.
How it works
From craving to reading in one evening.
1. Describe what you're craving
Setting, dynamic, tropes, dealbreakers — in your own words. Confirm you're 18+ once — then the book is planned around your premise.
2. Read the first chapters free
Your welcome credits cover the opening chapters. Judge the prose yourself before spending anything.
3. Binge the whole book
Generate the full manuscript from €5. When it is finished, download the editable DOCX for Word, Kindle or your e-reader app. Loved the cast? Generate the sequel.
Who this is for
For readers who want the alien to be alien.
Generating rewards exactly what the clone-flood punishes: specificity. The stranger your species and the more precise your kinks, the better the book fits — and book two keeps the universe.
“If I read one more identical ice planet, I'll terraform it myself.”Prefer listening? Audiobook narration for your generated library is in the works.
Common questions
Before you start.
Can it invent non-human anatomy and customs?
Yes — that's what the story bible is for. Define (or let it define) the species' biology and courtship rules and the book uses them consistently, in the plot and in the explicit scenes.
Do I have to confirm my age?
Yes. Explicit generation sits behind a one-time 18+ confirmation. This content is for adults only, and you set the boundaries.
Will it keep the characters straight?
Yes. The book is planned before it is written: every chapter is drafted against the same story bible (characters, timeline, canon), so names, motivations and plot threads stay consistent — and you can generate a sequel with the same cast when you finish.
Is it free to try?
Yes. Signing up gets you welcome credits — enough to read your first chapters free, no credit card. Complete books start at €5, one-time. No subscription required.
