There are basically two categories of chastity device for male slaves, the chastity tube and the chastity belt. Of the former type amongst the most popular is the CB3000. This has superseded the CB2000 which was a somewhat crude device. A tube encases the penis and is held in place by a ring behind the ball sack. It is important to get the sizing right for comfort and security and a number of rings and spacers are provided for this purpose.
The ring should be the smallest that can be fitted over the slave’s cock and balls and the thinnest spacer should be used to ensure the balls cannot slip out between the two halves of the device.
I now keep my slave permanently locked into one of these devices as it is the most unobtrusive of the type and can even be worn under swimming trunks.
However it is made from plastic (good for airline security scanners), is not particularly robust and not, in my opinion, very attractive to look at.
Other devices of this type are available manufactured from steel and I am at present investigation those from steelworxx, a German company. The product appears on the face of it rather more aesthetically pleasing.
The CB3000 is not totally secure and it has been known for slaves to get their cocks out of the device, though if the spacers are right it is unlikely that they will extract their balls. Inserts are available to trap the penis in its tube.
One type simply makes the entrance to the tube smaller but another has spikes which would be quite painful if the slave attempted to remove his cock from the tube.
But for complete security it is possible to use a genital piercing and an additional small lock (see Chapter 10; Piercing). My slave has a Prince Albert (PA) piercing in the end of his cock and another lock through this ring ensures total security Chastity belts are more complicated devices. Made from steel they consist of a waistband, crotch shield and chains which pass between the legs. These must be made to measure as they are totally unyielding but are very secure.
Additionally a thin strap between the legs can be used to secure a butt plug in place.
There are models available from Tollyboy (UK), Access Denied (USA), and Neosteel and Carrerra (Germany).
From an aesthetic point of view I think the belts look better on a slave than the tubes and the CB3000 is particularly unattractive compared with the steel ones. I guess it is chunkier being made from plastic. Additionally with the belt the slave can be kept plugged. However for long term wear under clothes the tubes win every time. They are smaller, can be worn under swim trunks and do not inhibit free movement which is often a problem with the belts when worn for extended periods under clothes. Some chastity tubes can now be obtained with a smaller tube in the end which is inserted into the penis and through which the slave urinates thus keeping the whole device much cleaner and extending times between necessary cleaning.
Cleaning is always a problem and should be carried out at least once a day for slaves in permanent chastity. This can usually be achieved with a power shower alleviating the need for the device to be removed. However belts with small drainage holes should be thoroughly cleaned every day or so to remove the build up of secretions which every male slave seems quite unable to control.
A word about butt plugs. These can considerably increase the slave’s feeling of total control by his Mistress and the use of the slave’s anus by his Mistress adds greatly to his humiliation. A Mistress requiring the use of her slave's anus for say a strap-on or electro anal torture should open him up gradually by increasingly extended use of a butt plug. Do not use water based lubricants with butt plugs as they are quickly absorbed by the skin.
The lining of the anus is very delicate and quite easily damaged so anything inserted must be well rounded and very smooth. Petroleum jelly is the best lubricant and will not be absorbed.
Start with a small plug and increase the size and length of time gradually until the slave can take whatever you require for as long as you wish.
Recently Neosteel have introduced an electric plug with a remote control to fit the chastity belt. The transmitter has a range of up to one hundred metres so can be used it to summon the slave and send him coded signals when he is performing personal services.
Penis wands
Penis wands or prince's wands are smooth steel tubes which are inserted into the urethra and held in position with screw pins through the genital piercing.
For long term wear the smallest size should be chosen (6mm in diameter). If the wand is to be used in conjunction with a chastity tube or belt the section which is inserted into the penis should be fairly short (3 to 4 cm) or the penis will not fit into the CB. It is also a good idea to order a wand which protrudes about 1 cm from the end of the penis as this can extend beyond the end of the CB making the whole thing much cleaner when the slave pees.
There is nothing worse that a smelly slave.
It is a fact that most slave's penises drip with pre cum when the slave is aroused. A penis wand can prevent this as they usually have a screw in plug at the end which can be fitted with a ring. The plug is removed when the slave pees and then replaced.
My slave:
My slave is kept in chastity 24/7/365 wearing either the CB3000 or the Access Denied belt with the 3000 being worn approximately 60% of the time. Additionally he has a short penis wand secured in his PA piercing.
During the night and also during the day when I am away from the house it is the 3000 that he wears. It allows more freedom of movement for the tasks I have set but I do not much like seeing my slave's cock in a thick plastic tube. If it is locked away it should be invisible. If I want the slave's cock visible I have it properly displayed with the tip locked to the waist chain. It is then very vulnerable and the balls are nicely presented as well. It is good at times to see one's property on display even though I am never going to make use of it as intended.
I prefer the appearance of the belt and also like to have him plugged a lot of the time. Obviously in the home the slave is permanently naked so the problem associated with the belt and clothes does not apply. When I return home I usually have him remove the tube and either chain his cock as described or put him in the belt with butt strap locked on. This is good training for the slave to make him anally receptive but it took some months to reach this desirable situation.
Changing of the two devices is always carried out in my presence so the slave has no chance ever of a secret masturbation. I do not have to instruct the slave to do this; I simply throw the keys on the floor. He has been conditioned to swap the belts when I do this and then return the keys to me, held between his teeth. That which has just been removed is then immediately cleaned ready for its next use. The keys are kept in my purse.
Update:
I have recently discovered a device from the USA called 'The Helmet'. This is by far the best chastity device I have come across for long term wear.
Made from metal it is robust and totally encloses the slave's cock and balls, preventing all access. It also enables the use of the whip in this area without the risk of causing damage. I have substituted the original locks at the side for one at the front and this is used to secure the cover. The same lock passes through a short chain attached to my slave's PA ring. Thus the device is totally secure.
In addition I have dispensed with the elastic waist band and 'The Helmet' is permanently attached to my slave's waist chain.
