Power exchange
Power exchange is the agreement by which one person hands control to another, and it is the idea under everything on DesireBorn Bound. The name is precise: it is an exchange, not a theft. Something is given and something is received, and the interest of the story is in what each person gets out of it that they could not get any other way. Readers who know the territory use the phrase for the whole dynamic, from a scene that lasts an hour to an arrangement that structures a life.
What the term means
The phrase comes from the BDSM community and has been in use for decades as the general name for dominance and submission dynamics. It was chosen over words like control or obedience because it describes both sides. Power is not simply taken by the dominant. It is offered by the submissive, on terms, and the dominant accepts the responsibility that comes with it. Some people argue the word should be transfer rather than exchange, and the argument is worth having, because it points at the thing beginners miss: the submissive gets something back.
What comes back is the subject of most of the stories on this site. Safety. Attention. The relief of not deciding. Being seen precisely. Being held to something. The catalogue entry describes the theme as who holds it, who gives it, and what it costs them both, and the last clause is the one fiction tends to drop. Power exchange written well is expensive for both people. The dominant is carrying responsibility; the submissive is carrying trust. Neither is passive.
A scene, a dynamic, and total power exchange
The phrase covers three different scales, and confusing them is the most common mistake in writing about it.
A scene
An hour, an evening. Power is handed over at the start and handed back at the end, and both people know when each happens. Most fiction about power exchange is really about scenes, which is fine, but the beginning and end should be visible.
A dynamic
An ongoing arrangement inside a relationship: rules that persist, roles that persist, an authority that does not switch off when the scene does. It may be light or heavy, but it is there on a Tuesday afternoon.
Total power exchange
Usually shortened to TPE. The submissive has handed over authority across the whole of life, continuously, with the dominant's decisions standing in every area they agreed on. It is rarer than the internet suggests and more carefully negotiated than fiction shows. On the page, it is the version where the story has to be honest about cost, because the cost is everywhere.
What is exchanged
The dominant receives control, and with it the obligation to use it well. The submissive receives structure, attention and the particular freedom of not being in charge. Readers who tick this theme are usually clear about which side of that exchange they want to read from, and the engine writes the interior of both.
The thing most easily forgotten is that the dominant is also giving something: time, thought, vigilance, the work of noticing. A dynamic where the dominant only takes is not power exchange. It is neglect with a vocabulary.
Power exchange versus dominance and submission
They are nearly the same thing seen from two angles. Dominance and submission names the roles. Power exchange names what passes between them. A story can have dominance and submission as a mood, in tone and posture, without any actual exchange; a story with power exchange always has something concrete that was handed over, and the reader can point at it.
How it is written so the exchange is visible
The failure mode is control without a transaction: a dominant who is simply forceful and a submissive who simply complies. That is a mood, not an exchange, and it reads as one.
Show the handing over. Somewhere early, on the page, one person gives the other something specific: a decision, a rule, a word that will be obeyed. The reader has to see it change hands.
Show what comes back. The submissive should visibly receive something they wanted: being held to it, being watched, being relieved of a weight. Without that, the story is about one person and a prop.
Show the cost on both sides. The dominant's attention should look like work. The submissive's trust should look like risk. The moments where one of them pays are the moments the reader believes it.
Register the shifts. A dynamic that changes should be seen to change. If the terms move in section nine, the story should know they moved.
"You decide," she said, and then, because he waited, "I mean it. Tonight you decide all of it."
He did not say anything for a while. She had expected him to look pleased. He looked like a man who had been handed something heavy and was working out how to carry it.
"All right," he said. "Then the first thing I decide is that you tell me if that stops being true."

How the engine handles it
This theme is the genre's centre of gravity, and on Bound the engine treats power as the subject of every scene: legible as an exchange of control, who gives it up, who takes it, what it costs, what each gets. The story state carries the terms of the exchange and registers any shift in them, so a dynamic that changes in section nine is known to have changed. The interior of both sides is written, narrowing and effort on one, attention and responsibility on the other, without therapy-speak. Nearly every other theme on Bound is a form of this one: negotiation and limits is how it is set, service and protocol is how it is lived, aftercare is how it is put down.

How to ask for it in a story
Name the scale and the transaction. Something like: this is a scene, not a lifestyle, she hands him control at the door and gets it back at breakfast, and what she gets in between is being watched more closely than she has ever been. Or, for the heavier version: an ongoing dynamic where his authority holds outside the bedroom, and the story is honest about what that costs both of them. The heat levels guide says how explicit each level gets; power exchange reads at every level, because the exchange happens before anyone undresses.
Every character in a sexual context is an adult. That is the one term no exchange can move.
