Futanari story generator
A futanari story generator writes futa fantasy between adults — anatomy that breaks the usual script, and everyone in the room adjusting to it.
Futa works best when the anatomy is treated as a fact of the world rather than a reveal to be gasped at. That frees the story to be about what it changes: who leads, what surprises whom, and how quickly everyone stops being polite about it. SecretPen writes it matter-of-factly, which is oddly hotter than the alternative.

Three openings to steal
Click one and it lands in the desk, already typed. Change any word you like — it's a starting line, not a script.
She mentioned it in passing
She tells me over dinner, entirely casually, as a logistical detail — and then watches, amused, while I try to keep my face doing something normal.

The flatmate
Two years of sharing a flat and one badly-timed morning in the corridor, and she doesn't rush to cover up, and neither of us moves for slightly too long.

Both, actually
I'd assumed I knew how tonight would go. About twenty minutes in she informs me, with obvious enjoyment, that I have the entire evening backwards.

What makes Futanari land
- Establish it early and move on. A long reveal wastes the premise.
- The dynamic shift is the story — who's in charge now that the script is gone.
- Let someone be delighted rather than shocked.
How far it goes
Futa and dickgirl fiction across fantasy settings, magical transformation, sci-fi modification, futa-on-female, futa-on-male, futa-on-futa, harem and group scenes, and the domestic version where it's simply an unremarkable fact of the relationship. SecretPen establishes the anatomy early and moves on rather than staging a long gasping reveal, which frees the story to be about what it changes.
How it works
01
Say it in one line
One sentence is enough. Who's in the room, and what has already been decided between them.
02
Set the dial
Tone, heat, point of view, length. Or skip it — the defaults are tuned for people who'd rather just read.
03
Keep going
Chapter one arrives in seconds. Steer the next one, change your mind, or let it run.
Nobody else reads this.
SecretPen has no public feed, no community rankings, and no way for one reader to see another's stories. Whatever you write here stays in your account — that's the whole point of the name.
Start writing →Questions
- Does it need a fantasy setting?
- No. A contemporary story where it's simply a fact of the world works fine, and the matter-of-factness is often hotter than a magical explanation.
- Can she be dominant, submissive or neither?
- Any of them. The anatomy doesn't fix the dynamic — say who's in charge and SecretPen won't default to the obvious answer.
- Is any of this public?
- No. SecretPen has no public feed, no community rankings and no sharing — there is no mechanism by which one reader can see another reader's stories. Everything you write stays in your account.
- How explicit does it get?
- As explicit as you ask for. There is no fade to black and no lecture. The only limits are the hard lines in our content guidelines: everyone is an adult, nobody real, nothing illegal.
- Do I have to pay to try it?
- No. You can write your first story free. Paid plans exist for people who write a lot of them.
