Technical perspectives on the design of female Chastity Belts for long-term wear

Dedicated to the most Gracious Chaste Lady of Italy

Submitted by: Florian d’Aguincourt - aguincourt@yahoo.com

The objective of a CB is to deny to its wearer sexual activities: masturbation, vaginal intercourse and eventually anal penetration. This objective, given the motivation of the wearers and the female anatomy, is quite a challenge and necessite from the designer much ingenuousness and determination.

This essay addresses the technical aspects of chastity enforced on an "average" woman, who orgasms during clitoral or vaginal activities. For obvious reasons, this article cannot concern the situation of the many women who can climax with other manipulations.

Overview of the methods:

Denial can be achieved by 3 means: physical blockade, infliction of pain in case of attempt, seal and deterrence.

Seal and deterrence

By "seal and deterrence" I mean a condition in which the wearer has to break or alter the CB in order to conduct illicit activities and in which such tempering, once noticed by the Keyholder, carries consequences feared by the Belted. Actually, all CBs function with some deterrence effect. There is no CB that could not be opened with modern locksmith tools or - if push comes to shove- manufacturing equipment. Thus, a CB functions purely on its mechanical merits alone only in places where the Belted has no access to tools -like, say, Saudi Arabia-. This does not mean that a CB doesn't need solidity to do its job. Quite in contrary: the belt, by opposing a staunch resistance, tests the intentions of the wearer and give her the occasion of "think it better".

Let us imagine a married couple. They love each other deeply and want to stay together. Regrettably, "she just can't say no" and has short affairs like pearls on a necklace, a situation her husband cannot support anymore (let us also assume that counseling etc. failed). They decide that she should wear a CB. If all it takes to open the belt is a pair of scissors, the belt has a low threshold value and may not be sufficient to protect its wearer of temptation. If in contrary, the CB requires heavy tools to be opened, it will give to its wearer more time to come to reason. Its impregnable aspect alone will probably sufficient to dissuade her of any action. Note that in this case, the belt would only have to blockade the wearer's vagina and should leave her clitoris free, so that she could satisfy her libido, at least partly, by way of masturbation, which is allowed here.

Pain Infliction

Pain inflicted to the wearer if she engages in forbidden activities can thwart any chance of orgasm or be so excruciating that the wearer has no choice but to stop. A high-tech belt would for example detect a stealth hand heading toward the clitoris. It would respond by inflicting to the wearer electrical discharges, say, inside her vagina as it is a place out of her reach and well sensitive.... The intensity of the current would be first low -a "friendly" warning- and rise into the unbearable if the wearer persisted in her forbidden endeavor. (we suppose that the wearer is pain-shy). The induced suffering would deter the wearer of continuing her masturbation and also distract her of any pleasant thoughts, making so an orgasm impossible. The neatest design leaves the wearer’s clitoris open to her caress, but punish any serious arousal...

So much for the theory. In the practice, however, it is almost impossible to build sensors that can discern between illicit activities and allowed movements: is the wearer taking her breath or is she trying to get her hand under the belt? Is this wetness the prelude to a forbidden orgasm or is it the result of aerobics followed by the shower? Even if tension and pressure sensors (I think here of piezzo-quartz or conduction strips) could be fitted and feed a control unit with useful data, the amount of programming and testing needed to design a safe belt is way out of reach for the amateurs and craftsmen no matter how gifted they may be.

This is a pity, but the consequences of an electrical belt running amok could be mutilating or even lethal and therefore leave no room for trial and error investigations. To the one nevertheless tempted, I suggest the following experience: get 2 big flashlight batteries together and make a short-cut using one copper thread only (taken from a good hi-fi cable). See how it glimpse and burns away in a second? I know that it is scientifically dishonest to infer anything concerning the human body, but it illustrates one major point: even low voltage (here only 3 volts) from a modest source can do a lot of damage!

Physical Obstruction of Vaginal Sex

Of all sexual activities to forbid, vaginal sex is the easiest to block and this for simple physical reasons. The blockade can be performed in 3 ways: Shield; Piercing, Insert in the vagina.

Piercing

Each method has pro and cons. Piercing presupposes the willingness of the wearer to undergo permanent body modification. if this is the case, a little lock and possibly 2 rings will securely deny to the wearer any penetration. The main advantage of piercing lays in the smallness and thus discretion of the required device. A women submitted to this form of enforced chastity can wear mini-skirts, tight jeans and go to the swimming pool without fearing that her condition may be ever discovered.

Another advantage lays in its potential permanence. Imagine a lesbian couple engaged in B&D. The submissive has strong bisexual tendencies and this infuriates her mistress who is exclusively lesbian. The sub want to give to her mistress a token of her fidelity and of her commitment to their chosen lifestyle. What could be a stronger proof of love and dedication than the following? she gets her small labiae pierced. Then she let her mistress put a ring on her, with the ring's pin going through her pierced labia into its receptacle, like any earring. The difference being just a very small drop of araldite glue in said receptacle.... a very dramatic effect would be reached by the wearer if she were to inform her mistress only after she put the ring. The dialog could be:

Sub: I pledge to stay away from men as long as I wear the ring you just put on me.
Dom (impatient): big thing! I know you: as soon as you see a cock, this ring will fly into the dustbin. Nice ring BTW, I like its pure form, no obnoxious mechanism... I like it. Now how do you close and open it?
Sub: I don't.
Dom, closing a firm hand on the ring: Its "i don’t, Mistress". Now answer my question pronto and with more deference or else...
Sub (afraid and now very respectful): please mistress have a close look. It really can't be opened. You just sealed my pledge!
Dom (impressed with tears of joy): oh my dear little slave. how sweet and brave from you!
They lived happily ever after and had no kids...

The main draw-back of using piercing to enforce chastity lays in the potential wounds that the wearer may suffer in case of a forceful removal. A rapist for example would surely not be stopped by a little lock and would inflict tremendous pain and awful scars to his victim by tearing the ring or lock.

Inserts:

The second most discreet chastity device is the insert: An oblong shape, the size of a small dildo is introduced in the vagina and maintained there by a crotch-band which is itself bound to a waist belt. The whole is thus quite similar to a classical chastity belt, with one major difference: the bands don't need to be very strong or tight. They only have to prevent the wearer of" pulling the plug", if I may say so. This can be achieved with a level of tightness far lower than what a shield would request to protect the wearer from penetration. The insert can have a vibro- or a punishment function in addition to the enforcement of chastity.

By keeping the wearer simultaneously chaste but penetrated, the belt with insert sends a very powerful message to her. Equally powerful is the symbol that she projects to her KH: I am willing not only to put my sexuality under your control, but also to be constantly penetrated by you. The only drawback lays in potential allergies and chaffing which - given their location - could be much more than irritating.

Shields:

One major feature of the insert is ability to fix a belt in relation to the genitals of the wearer. This geometrical - one is tempted to say geographical - relationship is the main challenge facing CB with shields. the shield has to cover the vagina but is physically _not_ linked to it. Its position is determined by the triangle Hips (or taille) to Crotch. Thus, in order to protect its wearer, the belt must enclose her tightly and be rigid. A belt must exert a strong traction between waist band and shield, thus pushing on the waist to press the chastity shield on the wearer's genitals. Otherwise, the wearer may contortion her way out of chastity. The commercial steel belts all seems to fulfill this function quite well, according to the numerous postings on the net.

Denying Masturbation

While the commercial belts are very successful against vaginal intercourse, they usually fail to deny masturbation to the determinated wearer. The reasons why CBs are more easily defeated by masturbation than penetration may be obvious, but to formulate them helps the research for counter-measures. First, it is more easy to stop something rigid (it better be!) with the diameter of a penis than something as small and articulated as a feminine finger. Secondly, penetration is perpendicular to the body's surface while pushing fingers toward a clitoris is parallel. Thus, to block a penetration, the shield must keep its position relative to the body within a tolerance approximately equal to the diameter of a penis plus half the width of the shield beside (not covering) the vagina.

Masturbation, in comparison, asks for significantly more tightness: the incursion is parallel to the body. Thus the distance between body and shield becomes crucial in place of the relative position. The width of the space between the wearer and her belt must be kept at any time below the diameter of a feminine finger. This may still sound a lot, and it would be more than plenty if the wearer were a marble statue. However, it's not statues who need CBs but women of flesh, of a very flexible, compressible flesh driven by a very determined spirit. If it were not for the pelvis bone, the prevention of masturbation would be an unrealizable dream, but even so, it is an almost impossible task.

The ideal belt?

Here are a few features that - according to my technical observations - would help a belt to prevent manual masturbation:

Take the bone structure more into account. The constellation of hips/taille, pelvis and coccyx allows to secure a belt in the 3 dimensions and on the 3 rotation axes with a very small tolerance.

A wider, anatomically shaped, waist band. A wider waist belt means a bigger surface to carry the forces caused by the belt (traction on the waist to push the shield against the wearer’s sex). This in return allows for a stronger push on the shield with equal or lower pressure on the hips. An anatomic shape (like a small corset) will also add to the comfort of the wearer while allowing a closer fit.

A unique rear band. Two bands running over the buttocks includes in the mechanical system two highly flexible volumes. A unique band goes over a bony area (a.o., the coccyx) and thus give a lot less leeway.

Fix rigidly the front band to the waist band, so that the rigidity of the waist band helps to keep the position of the chastity shield.

the shield's shape must follow exactly the shape of the wearer' genitals not only on the surface but also in the depth. Usual CBs are cut so that they follow the outer shape of the body, but they do this only on one planar surface. The reasons for this are of two kinds: anatomic and technical. The feminine anatomy varies so much from one woman to another, it is so plastique that useful measurements become unobtainable without extended testing. Even if a correct shape were to be measured, the manufacturing process to produce such a 3-dimensional shape is far behind the means of the average craftsmen. To forge a metal plate into the complex shape smugly espousing the sex of the wearer requests moulds and forces only available in the manufacturing industry.

Two processes can fit the requirements: spark-erosive manufacturing and milling. Both can cut almost any shape out of massive steel. Spark erosion cut the toughest steel by a series of sparks in a liquid basin. Each spark takes away a microscopic particle of steel. This gives the highest flexibility in term of form and raw material. The hardest titanium alloy can be carved that way. However, the machines are very expensive and their handling better left to specialists. Milling, on the other hand is less flexible in term of raw material and possible end-shape, but a lot more accessible to the layman. Differently shaped tools make almost every form possible at a very reasonable cost.

The optimal chastity shield looks -according to the precedent observations - thus so: a full metal body as wide as possible, thick (0.5-1 in.), its external contours cover the pelvic bones. In the length, it is bent to follow exactly the curve of the body, from the pubis to round the anus. Actually, it should be bent slightly more so that it gently squeezes the genitals of the wearer.

The inner side has 2 shallow pockets for the big labiae. between them is a deeper pocket for the small labiae and the clitoris. The pocket is wider around the clitoris, so that there is no contact between it and the shield.

In the deeper pocket, between the small labiae, protrudes a sort of stump fin with an ellipsoidal section which penetrates the vagina without distorting it. The pocket also has 2 small holes to the outside, one above and one below the clitoris. The lower hole allows the wearer to urinate. Afterward the wearer can connect a syringe to the higher hole (w/o needle!) to, well, flush.

The stump fin has two functions: it positions the shield directly in liaison with the wearer's genitals. This means that if the wearer try to push her shield aside, it will push her genitals in the same direction, hindering any sneaky manual intrusion. this principle can even be pushed further. The fin could be a rigid axis between the shield and a vagina insert. The insert, a slightly flattened dildo shape, presses against the frontal side of the vagina, therefore, the clitoris area would be hold firmly but without excessive pressure in a clamp consisting of the shield, the fin and the insert. Any attempt by the wearer to reach for her clitoris will fail, since a pull on the shield to get more room underneath would also pull the insert, which in turn would push the clitoris against the shield. The whole system is also rigid enough to resist the forceful intrusion of a hand sidewise.

The only problem is the possible reaction of the body (allergy, rush) but a smooth finish and a coating in gold may be the answer (it would also look very nice, wouldn't ’t it?)

A very discreet lock

The CB closes in the front by the mean of a bolt secured by a rod. There is no apparent mechanism, especially no lock, just the two front plates and some rods for rigidity. The locking rod is 3mm in #diameter where it locks the bolt but slims down afterward to become a flexible shaft that goes through the front band down to the chastity shield. A hole, ca. 1in diameter, 1/2 in deep is drilled in the lower side of the shield, opposite to the wearer's vagina and thus to the fin. the locking rod comes out perpendicularly in the hole and protrudes when the front shield is open. It disappears when the front shield - and therefore the belt- is closed. To lock the belt, a small cylindrical lock is introduced in the hole and keyed. In the locked position, the rod is blocked by the cylindric lock, keeping therefore the bolts in position. Thus, the lock does not cause any bulge and the belt’s shape remains very smooth.

Conclusion:

A chastity belt built on these principles will be very tight but yet comfortable. With no bulge, especially for the lock, it can be worn under reasonably fitting garment. While allowing its wearer a complete freedom of movement, it will deny her any orgasm, as long as she is the kind of woman who needs clitorical of vaginal stimulation. Well, these are my assumptions, and nothing more. The belt has still to be manufactured and tested. I hope that then, all what I wrote will prove to be more than wishful thinking.
