Inflation story generator
An inflation story generator writes a body swelling past its limits — pressure, tightness, and a change nobody can hide.
Inflation is a pressure kink, and pressure is a sensation most writing has no vocabulary for. What makes it work is the interior experience — tightness, weight, clothes stopping fitting mid-scene — plus a rate of change slow enough to be felt. SecretPen writes it from the inside rather than describing a shape from across the room.

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.
Halfway through dinner
It starts somewhere around the main course and by dessert I have my arms crossed and a very serious problem with the fit of this shirt.

She has the dial
There is a dial, she has it, and she has been turning it up by increments so small that I cannot pinpoint a single one of them.

Not reversing
The effect was supposed to wear off in six hours. It has been eleven and nobody is panicking yet, but somebody is about to.

What makes Inflation land
- Rate matters. Slow enough to be felt, fast enough to be alarming.
- Clothes are the measuring device — what stops fitting, and when.
- Someone watching who is enjoying it far too much.
How far it goes
Body, belly and breast inflation, expansion and growth, magical, technological and cum-based causes, gradual and rapid, reversible and permanent, inflation inside a transformation or bimbo arc, and the version where the character can't stop it and someone else holds the control. Between adults, written for the sensation rather than the diagram.
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 write it from the inside?
- Yes — ask for interior sensation and you get pressure, tightness and weight rather than an external description.
- Can somebody else control it?
- Yes, and it's the stronger version. A dial in another person's hand converts this from a transformation into a control kink.
- 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.
