Size difference story generator

A size difference story generator writes the physical gap as the fantasy — being lifted, covered, held, and made to feel very small.

Size kink is about scale being felt rather than stated. A hand that covers too much, a doorway they have to duck through, being moved without effort. SecretPen writes the ordinary moments where the difference shows up — those do more than any number ever does.

What makes Size difference land

How far it goes

Size kink across tall-and-small human pairings, monster and orc partners, giants and shrinking, shifters in and out of form, strength differences without size differences, and the domestic version told entirely through shelves, borrowed shirts and being moved out of the way. SecretPen writes scale through ordinary actions rather than measurements, which is the only way this kink reads as felt rather than stated.

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.

Questions

Does it need a fantasy setting?
No. Two humans with a real height and strength gap works perfectly, and the everyday version — being lifted onto a counter mid-argument — is often the better story.
Can the smaller one be dominant?
Yes, and it's a great dynamic. Something enormous deferring completely to someone half its size is one of the most reliably good scenes in the genre.
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.
