Chastity Contract: Clauses That Matter, With Samples

A chastity contract is a written agreement between the person in the cage and the person with the key. It fixes the term, says who holds which key, lists what gets the device off and for how long, and spells out what a broken rule costs. It isn't a legal document. It's the negotiation you'd have anyway, on paper, so that on day nine, when one of you is grumpy and the other is bored, you can both point at the page instead of arguing from memory. The same page works as a rulebook for an AI keyholder on KinkSim, where a lot of people run a first term.

What a chastity contract is for

Search for a chastity contract template and you'll find documents that open with "the undersigned hereby surrenders all rights to his penis" and run for six pages of whereas clauses. That style is theatre. Fun theatre, some nights, but it hides the job the paper is there to do.

A D/s contract isn't legally binding anywhere I've heard of, and consent to anything done to your body can be withdrawn at any moment no matter what got signed. An attorney quoted in Cuffplay's D/s contract guide calls it "a written record of negotiations, not a binding contract," and that's the right frame. The value is in the writing, because writing forces specifics, and every vague phrase you tighten is a fight you won't have in week three.

Wearers pester. Keyholders forget. A written term with a check-in rhythm and a release rule leaves the wearer nothing to negotiate and gives the keyholder a calendar instead of a nagging partner.

The chastity contract clauses that matter

Write them in whatever voice suits you, cold and formal or warm and filthy, but write all of them.

Parties, device and term

Name the roles, name the device by model, and give the term a start date and an end date. Two weeks is a good first term. LockedCage's keyholder guide suggests first lockups of hours rather than days, so inside those two weeks write "a few hours a day in week one, overnight from day eight." A contract that reads "until the keyholder decides" has no term, and I wouldn't sign it.

Release conditions

List every reason the cage comes off and for how long. Hygiene on a schedule, medical, airport security if the cage is steel, sex with the keyholder if that's on the menu, orgasm if and when the keyholder grants one. Write whether a release for sex means an orgasm, a ruined one, or nothing at all, because "unlocked" and "allowed to come" are different events and a lot of arguments live in the gap. If orgasm denial is the draw, say how often a release is even on the table.

Hygiene

Daily cleaning in the shower while locked, and a full removal to wash and inspect every two to three days. Skin under a cage sits warm and damp, which is how yeast and pressure sores start. In a remote dynamic the hygiene opening doubles as the safety inspection, so a photo of the skin around the base ring belongs in the clause. Chaster's hygiene opening extension (checked September 2026) defaults to every two days with a fifteen-minute window and adds twelve hours for overrunning it.

Emergencies and the medical stop

Define an emergency before you need one. Numbness or tingling that doesn't clear within a few minutes of adjusting, color change to pale, blue or purple, swelling that keeps growing, broken skin, trouble urinating, fever. Any of those and the cage comes off now, with no permission asked and no penalty applied. Write that down, because a wearer who thinks an emergency removal will cost him a week hides the symptom instead. Numbness that lasts past fifteen minutes after the cage is off, or color that hasn't returned within twenty, is a same-day doctor visit.

Safeword and check-ins

Green, yellow, red works for chastity as well as it works in a dungeon. Yellow means "this needs adjusting, talk to me tonight." Red means the device comes off and the term pauses. Write that calling either color is never an infraction. Then set a check-in rhythm, a one-line daily report on fit, skin and mood, and a longer talk once a week out of role. The kink roleplay safety and consent guide covers how that out-of-role layer works.

Rules, punishments and rewards

Keep the rule list short enough to remember while aroused. Three to five rules beats twenty. Punishments need a menu and a ceiling. "Added time, maximum three days per infraction, one week per term" is a clause. "Punishment at the keyholder's discretion" is a blank check that grows the term every time the wearer gets whiny. Rewards deserve a line as well; a keyholder who only ever adds time is running a sentence rather than a dynamic.

Renegotiation and the end date

Say when you'll review (the end of term is the obvious moment) and what a new term requires. A line reading "either of us may end this agreement at any time, without cause, by saying so out of role" belongs in every contract. If one party won't sign that line, you have a bigger problem than paperwork.

Sample chastity contract wording

Initials stand in for names. Swap the roles and the numbers.

• "This agreement runs from Monday 15 September to Sunday 28 September, when it ends unless we both sign a new one."
• "Two keys exist. J holds one. R keeps the second in a numbered tamper bag on the bedside table."
• "R is unlocked for fifteen minutes every second evening to wash and inspect, and sends J a photo of the skin around the ring before locking back up."
• "R may remove the cage at once for numbness, color change, swelling, broken skin, trouble urinating or fever, and for any medical or travel need. Emergency removal is never punished."
• "R does not ask when release will happen. Asking adds one day, to a maximum of three days per week."
• "Yellow means adjust and discuss tonight. Red means the cage comes off and the term pauses. Neither is an infraction."
• "If J is unreachable for twenty-four hours, R may unlock and the term pauses until we talk."
• "Either of us can end this agreement at any time by saying so. Ending it is not a failure and needs no reason."

One contract I read while researching this ran four weeks, gave the wearer the emergency key, and wrote feeding the cat into his duties. That's the register to aim for.

Keys, and the emergency key argument

Say how many keys exist and where each one lives. The usual shape is a primary key on the keyholder's person or in a lockbox, and an emergency key with the wearer. Templates where the wearer never has a key are fantasy writing. LockedCage says a spare should be reachable within sixty seconds, and Chaster's documentation tells wearers to keep an emergency unlock method accessible before starting a lock. A cage sits around tissue that swells three to five times a night whether the wearer wants it to or not, and things go wrong at 3 a.m.

So the wearer keeps a key, and the contract's job is to make using it visible. A tamper-evident bag with a serial number, a lockbox whose combination sits in a sealed envelope, a numbered plastic seal through the padlock. Any of those turns "did you cheat" into a thing you can verify instead of argue about.

Using the emergency key for a real reason doesn't break the contract. Using it because the term felt long does, and the contract should price that. Chaster makes a wearer who abandons a lock wait seven days for the combination and logs it against their record.

Mistakes that end chastity dynamics

• No exit clause. One sample I read sets a five-year minimum and allows cancellation only by mutual agreement, death or serious illness. Anyone who tries to hold a partner to that has left kink for something else.
• Punishment escalation. Added time sounds fair until the infractions are "asked about release" and "seemed sulky," each worth a week. Six weeks in, the term is a year, the wearer has quietly given up, and the keyholder holds a key to a dynamic that ended a month ago. Cap it.
• Keyholder powers the keyholder didn't ask for. Wearers write most of these, and they write in "may seal or damage the device" or "may post the wearer's photos anywhere." Both people write the thing, across more than one sitting.
• No review date. A document no one revisits describes a dynamic that no longer exists.
• Treating the safeword as a loophole. If red costs the wearer anything, it has stopped being a safeword.
• Real names and legal styling. Use scene names, keep the file out of the shared family cloud folder, and skip the notary.

The keyholder's side of a keyholder contract

Most guides are written for wearers, which says something about who wants the arrangement more. The keyholder is signing up for work: a daily look at the skin, remembering the hygiene night, holding a release date they'd rather forget, and absorbing the whining without caving. Write their side too. Put down what they commit to (a daily check-in, a reply within a day), what they don't (unlocking on request), and what they get, usually service and attention with the tap turned off.

A reluctant keyholder is the most common failure in couples, and a shorter contract with fewer duties fixes it more often than a longer one. If your partner's whole contribution is "I'll keep the key in my jewelry box and check in on Sundays," write exactly that. In a femdom relationship the chastity clauses usually sit inside a broader agreement; keep the emergency and exit lines when you merge them.

A chastity contract for an AI keyholder

The same clauses work as a rulebook for a chastity AI character. An AI keyholder holds terms, tallies and a strict voice across sessions and will remember Tuesday's infraction on Friday. It cannot see your skin, hold a physical key or unlock anything, so you always keep your own key and the release conditions are yours to enforce. The chastity and denial roleplay with AI guide covers setting terms so they hold, and the chastity tag is where the keyholders live.

If you're new to the device itself, read how to put on a chastity cage before you sign anything. Once the paper and the fit are settled, chastity games is where the fun goes.
