Chapter Fourteen
The Toys

“The world’s so full of a number of things,
I’m sure we must oil be as happy as kings.”

– R. L. Stevenson, A Child’s Garden of Verse

So far in this book we’ve examined the background and theory you need to understand basic electrical play. This is all very well and good and damned important too, but there is the real world out there. This is the world that has all the good toys that we can play with. Mow I’ve mentioned the names of some electrical play toys in the course of the theory discussions. Generally these were ones that most of you had already heard of , thus providing you with a concrete picture to illustrate the theory. But in this chapter I will describe a wider range of electrical play toys that have been used in the scene.

The way I’ll be doing this is in the form of tables showing the characteristics of each toy. In this way you’ll be able to compare the different toys on the different points and can choose one or more best suited to your particular play. These tables will also give you a familiarity with the different types of toys and the kind of results you can expect from them. Using your understanding based on the theory you now know, you can plan their appropriate use.

The different categories show in the following pages are defined as follows:

Toy – The commonly known name of the electrical play toy. No manufacturer’s names are used here, as several manufacturers may make the same kind of toy. Sometimes a manufacturer will use a brand name to describe their toy but the general operating principle of their toy will fall under the common toy name.

Operating principle – A description of the general operating principles or theory by which the toy operates.

Voltage(s) – Identifies the generally expected output voltage(s) from the toy as applied to the body. Where appropriate it will also identify the input voltage requirements of the toy.

Current(s) – Identifies the generally expected output current(s) from the toy as applied to the body.

Frequency(ies) – Identifies the generally expected output frequency(ies) from the toy as applied to the body.

Body effect(s) – Describes the generally expected body effect(s) that users (bottoms) typically report. This is not a comprehensive list but only those most commonly reported.

Intensify – Describes the generally expected intensity (ies) that users (bottoms) typically report. These intensities are only qualitative and relative, and the ones most commonly reported. Individual users may vary.

Psychological Aspects – Describes the visual, auditory, and sensory cues available from the toy which may affect the psychological perceptions of the players in a scene using this toy.

Caution(s) – Lists the caution(s) in the use of the particular toy Apart from the understanding of the theory contents of this book regarding general cautions during electrical play, the caution(s) listed are those generally to be observed for that particular toy. A complete and comprehensive list is not attempted here since that may vary with particular manufacturers and the age and condition of the toy.

Toy: Carpet Shuffle Zap

Operating Principle: Rubbing your shoes across the carpet or taking off a wool or synthetic sweater inside on a cold day with very low relative humidity. This mechanical action strips off electrons (static electricity – see Chapter 4) that accumulate on the surface of your skin. You can then discharge these electrons onto a bottom’s sensitive body parts except for the eyes.

Voltage(s): High voltage static electricity discharge – about 25,000 to 100,000 volts.

Current(s): Low due to high resistance of the air and skin

Frequency(ies): DC of very short duration.

Body Effect(s): Electrons accumulate on top s skin surface and get discharged onto bottom’s body on the way to ground.

Intensity: Sharp, and mildly intense for a very short duration. Not very painful.

Psychological Aspects: Blue spark and mildly audible zap. Spark especially effective in the dark.

Caution(s): Relatively few. Don’t do it when you smell gas. Don’t do it on bottoms with heart problems.

Toy: (Piezoelectric) Acupuncture Zapper

Operating Principle: This is a moderately high voltage device used for acupuncture purposes. It works on the same principle as the burner spanker on some gas stoves, which is piezoelectricity. Piezoelectricity is the principle that if you hit certain crystals the right way the crystal will generate a voltage. In the case of the acupuncture zapper the voltage will not generate a spark. In the gas stove burner starter it will.

An acupuncture zapper behaves about the same as the carpet shuffle zap.

Voltage(s): High voltage static electricity discharge – about 10,000 volts

Current(s): Low due to high resistance of the air and skin

Frequency(ies): DC of very short duration.

Body Effect(s): Here the electrons generated from the piezoelectric crystal will transfer to the bottom’s skin. Since the zapper will contact the skin before discharging, there will be a small brief current that will affect the skin’s sensory nerves as it travels through the body to ground.

Intensity: Sharp, and mildly intense for a very short duration. Not very painful.

Psychological Aspects: There’s an audible l, “click” as the charge is generated.

Caution(s): Relatively few. Don’t do it when you smell gas. Don’t do it on bottoms with heart problems.

Toy: TENS Unit (Transdermal Electric Neural Stimulator) Also comes under other names such as Neural Stimulator Bio-Stimulator, Titillaior, et al.

Operating Principle: Basically a DC pulse generator. The TENS unit creates a pulse from direct current, using a variety of methods ranging from transistors to computer chips. Even though the unit generates pulses, it is not true AC; the voltage never goes negative. The pulses do, however, provide excellent stimulation of the nerves at the skin. Medical TENS units were originally designed for pain management of patients suffering from chronic pain.

The electrodes normally supplied with medical TENS units are about the size of dimes. They can also come with adhesive strips to attach to the skin for use. Toy variations of TENS units come with a variety of electrodes including clips, vaginal plugs, anal plugs, and penis electrodes.

Controls on the TENS units allow control of intensity pulse frequency, and duration of stimulation application (one second of pulses followed by one second of no stimulation, for example).

Voltage(s): Pulsed output voltages (to the bottom) are variable by control from 0 to about 10 volts. The units are usually powered by 9-volt batteries.

Current(s): Pulsed currents {to the bottom) of around I ma (milliamp). Current depends on voltage setting and skin resistance.

Frequency(ies): Pulse frequencies are settable from I to 30 or so pulses per second. Stimulation duration settings vary from instrument to instrument.

Body Effect(s): Bottoms mostly report tingling sensations.

Intensity: Bottoms mostly report mild to heavy sensations depending on where the electrodes are placed and the contact area of the electrodes. Milder sensations are felt using dime size electrodes on the skin. Heavier sensations are reported when using orifice plugs.

Psychological Aspects: Only the nerve stimulation is present, but the intensity, timing, and pacing of them is under the top’s control. This contributes to a feeling of helplessness, especially if the bottom is restrained.

Caution(s): Even though it is considered a mild device, tops and bottoms should concern themselves with the possible current paths within the body. There are generally very modest muscular effects from the unit, but the bottom may writhe in response to the stimulation being controlled by the top. There have also been cases reported of urethral inflammations such as cystitis or non-specific urethritis in women because of extended TENS stimulation in their genital area during a play scene.

Toy: Electric Fly Swatter

Operating Principle: The electric fly swatter looks like a small plastic tennis racquet, but with wires that are charged to a high voltage by an electronic circuit. The circuit uses a capacitor (for storage) and a small transformer – just like the flash unit on your camera. The swatter may or may not be effective on flies, but it’s very effective on body parts accessible through flies.

Voltage(s): High voltage – about 200 volts. It uses a 9-volt battery.

Current(s): High currents – 2 to 20 ma – but it only lasts as long as the capacitor is discharging (about I second), If you hold it against the skin, the electronic circuit will not have a chance to charge and the current will only be about I ma.

Frequency(ies): DC.

Body Effect(s): Since the metal grid of the swatter is applied in either a slapping motion or a brief touch, the higher current goes through a relatively small skin area.

Intensity: Sharp and intense for the brief duration that the circuit discharges and/or the swatter is applied.

Psychological Aspects: Initially it looks like a toy, but once the bottom has been zapped it may become an object of fear.

Caution(s): With the high voltages and currents in the fly swatter, you probably want to use it only on the lower extremities. The ass is the obvious and most desirable target for the swatter. In most cases, properly used, it can be almost as effective as a cattle prod, but slightly less intense and slightly safer.

Toy: Shocking Animal Collar

Operating Principle: This device is designed to keep a pet in the backyard without a fence or to discourage barking. A small electronic low voltage shocking device is placed in a pet collar. There is also a small radio receiver and a battery in the collar. When placed around the neck of the pet, a radio signal either from the master or from some sort of automatic sensor will deliver a mild shock to the pet. These collars have been used in scenes by placing them around the bottom’s thigh or adapting them for placement around the bottoms scrotum, so the top can deliver a shock at any time from anywhere in the house. A few models offer voltage control, but most don’t.

Voltage(s): Pulsed output voltages (to the bottom) are 9 volts – the same voltage as the battery.

Current(s): Pulsed currents (to the bottom) of around I ma (milliamp). Current depends on skin resistance.

Frequency (ies): Pulse frequency depends on the manufacturer’s design. Usually it’s 30 Hz or less,

Body Effect(s): Bottoms mostly report tingling sensations.

Intensity: Bottoms mostly report mild sensations.

Psychological Aspects: Only the nerve stimulation is present, but the delivery is under the top’s control. This contributes to a feeling of helplessness even if the bottom is not restrained.

Caution (s): Even though it is considered a mild device, tops and bottoms should concern themselves with the possible current paths within the body. There are generally no direct muscular effects from the unit, but the bottom may be startled and jump in response to the stimulation being controlled by the top.

Toy: Relaxacisor

Operating Principle: A higher voltage unit than the TENS unit. It can be either DC (pulsed) or AC. The voltages and currents are sufficient to directly cause muscle movement. There are usually only controls for intensity, not frequency or duration, although some relaxadsors have been modified by others to include such controls.

Originally relaxadsors were developed for submarine crewmen to exercise their muscles during underwater journeys. From time to time you’ll see commercial versions of such units advertised on TV for effortless exercise or muscle toning.

A relaxacisor unit usually comes equipped with four independent output channels and a variety of pad electrodes so that several muscle groups can be “exercised.“ The electrode pad generally requires a electrode contact cream or even salt water to make a good electrical contact with the skin.

Voltage(s): Output voltages (either AC or pulsed DC) to the bottom are settable from 0 to about 15 volts. Relaxacisor units are generally powered from house- hold outlets (120 volt AC).

Current(s): Currents to the bottom are dependent on the voltage applied and the skin resistance. Generally they’re less than 5 ma (milliamps).

Frequency (ies): Most models are AC, so there will be 60 Hz (Hertz) applied to the bottom.

Body Effect(s): Muscle flexing is the primary action of the relaxacisor. The amount of muscle flexing depends on the voltage applied r the electrode pad placement, and the quality of contact of the electrode to the skin. Generally tingling sensations are also reported.

Intensity: As for the tingling sensation of the sensory nerves of the skin, the intensity depends on the contact area of the electrode. For large contact areas a mild sensation is reported. For smaller contact areas more intense sensations are reported. The Involuntary muscle flexures usually don’t cause cramping, but some bottoms report anxiety over the muscle movements.

Psychological Aspects: As with the TENS unit, bottoms feel that they are at the mercy of the top controlling the unit Bottoms are subjected to tingling sensations and involuntary muscle flexures.

Caution(s): Because of the higher voltages involved the use of orifice plugs with relaxadsors is not recommended. Extended single play session stimualtion in the genital area of women is also contraindicated because of the reports of urethral infections. Also, since used relaxadsors are available from antique dealers and at flea markets, the unit may have insulation problems and transformer problems that could cause dangerous current levels to flow inside the body. Seeing as most relaxadsors are plugged into household outlets, there may be the opportunity for stray household AC voltages to be applied to the bottom under certain ad- verse circumstances. If you buy a used relaxacisor have it inspected by an electrical professional before you use it.

Toy: Toy train, doorbell, and other low voltage transformers.

Operating Principle: These are just ordinary low voltage transformers (see Chapter 7) that you can buy from an electrical supply house or hardware store. The outlet is applied directly to the bottom’s skin.

Voltage(s): The transformer secondary is usually a fixed voltage, generally around 6 to 30 volts. Train transformers in particular vary widely, with older models tending to be stronger. The primary is plugged into a household outlet (120 volts AC).

Current(s): The currents applied to the bottom depend on the voltages and the skin resistance. This can be anywhere from 1 to 10 ma (milliamps).

Frequency(ies): Household frequency (60 Hz).

Body Effect(s): Varies with the voltage, current, electrodes used, and points of contact. Bottoms can experience anything from tingling to muscle flexures to intense burning pain.

Intensity: Moderate to intense depending on what is used and how it is used. Some types of transformer offer no control over voltages, so those are an all-or- nothing sensation.

Psychological Aspects: There are not visual or auditory cues. There are just the sensations. For the uninformed user, they experience the same feelings as they do with a relaxacisor or TENS unit, but for an informed user there would be real fear from knowing about the dangers of using such devices.

Caution(s): It is highly recommended that you avoid orifice probes with low voltage transformers because of the lack of control. There are also dangers from excessive currents or even stray voltages from transformers – especially older ones which may be damaged. With so many other toys out there, the cheap price of a low voltage transformer is not worth the safety you lose.

Toy: Violet Wand

Operating Principle: A high voltage toy that uses a Tesla coil to generate the high voltages, Violet wands come equipped with a variety of gas-filled bulbs that glow when the high voltage is present. When the bulbs are in dose proximity to the bottom’s skin, a spark can jump. There are no contact electrodes that come with violet wands. Action is usually through the gas filled bulbs or by special attachments that allow the top to use his own body as an electrode. There is a control on the unit for the voltage.

Originally the violet wand was used as a medical device to treat everything from baldness to vaginal complaints to venereal disease. No cures were ever reported, but it did produce an interesting variety of gas filled probes, including one for the vagina and another one for the urethra.

Voltage(s): Generally 25,000 volts or more are generated by the Tesla coil. The violet wand is powered from a household outlet (120 volts AC).

Current(s): Generally around I ma (milliamp).

Frequency (ies): Household frequencies (60 Hz (Hertz)) are present because the violet wand is plugged into an outlet, but the tesla coil and the spark can generate weak frequencies in the megahertz range.

Body Effect(s): Skin sensory nerve stimulation is the object here. This car vary from the ants-all-over feeling as the gas bulb gets close to tingling at the point where the sparks jump to the skin. There is a small amount of heat in the spark, and burns can result from prolonged, continuous exposure of the spark to the same area of skin.

Intensity: Generally reported by bottoms as mild and sometimes pleasant. It can be up to moderate if a spark jumps to a particularly sensitive part of the body.

Psychological Aspects: With a violet wand you do have visual and auditory cues. There’s the glow of the gas in the gas-filled bulb and the blue color of the spark as it jumps to the skin. There is also a persistent buzzing from the Tesla coil mechanism as well as the hissing of the jumping sparks.

Caution(s): Violet wands should not be used around the eyes, as the sparks can cause severe damage. Also, the ultraviolet light given off can cause a sumburn or damage to the eyes. It has been reported that this heat from the spark is enough to set fire to flammable clothing and material such as rayon. Used violet wands are available in antique stores and flea markets, but they should be carefully inspected and tested by a qualified electrician or other technician before using. Some players combine violet wand and fire play by letting the sparks ignite small qualities of isopropyl rubbing alcohol (a 70% solution of alcohol En water) spread over the bottom’s skin which Es then immediately extinguished to prevent burning of the skin.

Since violet wands break down the air between the instrument and the bottom’s body, they generate ozone – a toxic gas. Be sure the room in which you’re playing is adequately vented.

Be careful to set up your violet wand play so that the bottom is not connected directly to your playroom’s grounding system – for example, with metal hand- cuffs attached to a water pipe. It’s best to use bondage equipment and materials of leather, rope, wood and other insulators for violet wand play.

Occasionally a spark will jump to the skin from the exposed metal of the gas bulb’s socket. Because of the lower resistance of the spark path the sensation from this spark is much more intense – possibly to the point of danger.

Most violet wands use a grounded plug. They should only be plugged into properly grounded household outlets.

Also DO NOT SUBSTITUTE ordinary bathroom plug chain for the special chain that some manufacturers supply with their violet wands. These special chains have high resistances built into them. Using ordinary chain would create a direct path through which 25,000 or more volts could pass directly to the body

Toy: Cattle Prod

Operating Principle: The cattle prod is an electronic device that generates a high voltage to the tips using a transformer. The unit is self-contained and has only a trigger to initiate the shock. There is no control on the voltage, It’s all-or-nothing. The trigger can be held down for continuous shocking. The original purpose of cattle prods was to control a ton and a half of angry pot roast, in other words, livestock. The high voltage was to be able to shock the animal through its thick hide.

Voltage(s): Output voltages at the tips of 25,000 volts or more. The voltage depends on the size of the cattle prod. Three or more high capacity batteries power the unit.

Current(s): Output currents of about 30 ma (milliamps).

Frequency(ies): Generally a single DC pulse when used to deliver single shocks.

Body Effect(s): Intense muscle flexures are reported by bottoms using cattle prods. Because of the small contact area of the electrodes there is also sharp and intense nerve stimulation. They have also been reported in a few cases to have burned skin, even to the point of scarring.

Intensity: Sharp and severe together with involuntary muscle jerking.

Psychological Aspects: Fear and anticipation of a painful shock is predominant here. Just waving one around without batteries causes people to shy away, and buzzing it can frighten someone quite a bit.

Caution(s): Heavy duty play toy which should ONLY BE USED on large muscle masses like the buttocks or the thigh muscles. A top using the cattle prod should be aware of potential muscle movement, Avoid using cattle prods in orifices because of the voltages involved. Also, the chest should be avoided due to the potential of cracked or broken ribs.

Toy: Stun Gun (e.g., Tensor, Electroshocker, and other names from various manufacturers)

Operating Principle: A personal defense device that generates a high voltage to the electrodes by an electronic generator. The device is self-contained and includes a set of electrodes. It is intended to disable an attacker by pressing the electrodes to the attacker s body and shocking him. When the device is held in the air, a spark will jump across the electrodes. A five second shock with the device will generally disable an attacker for from 5 to 15 minutes. There is no control over the voltage. The unit will deliver a shock as long as the trigger is held down.

Voltage(s): Output voltage across the electrodes is anywhere from 25,000 to 125,000 volts depending on the size of the units. The units are generally powered by 9-volt batteries.

Current(s): Output currents are about 30 ma (milliamps).

Frequency(ies): The frequencies of the delivered shock depends on the circuit used in the electronics of the unit.

Body Effect(s): Intense sensation and general muscular weakness. Once shocked a bottom will be unable to move for 5 to 15 minutes. There will also be soreness around the point of contact. Muscular contractions may be strong enough to crack bones.

Intensity: Severe and intense.

Psychological Aspects: The very visible spark and loud hissing sound of the spark will generally cause much anxiety and fear to a potential bottom. Tops using tensors often only use them to threaten rather than to actually shock.

Caution(s): Extremely high voltages are involved here with potentially intense body damage. If used for shocking during intense play scenes, top should be prepared to render assistance to the bottom as necessary, Do not use if you smell gas. Be especially careful where you point the unit if you don t intend to shock someone. Some jurisdictions allow tensors only to be in the hands of law enforcement agencies. You need to check you local laws before getting one.

Toy: Taser and other names from different manufacturers.

Operating Principle: A personal at-a-distance defense device like a tensor that also generates a high voltage to the electrodes by an electronic generator. The device is self-contained and includes a set of electrodes that are fired into the attacker by a spring loaded gun on the main body of the weapon. Metal wires connect the sharp pin electrodes to the main body of the unit. It is intended to disable an attacker by shooting the electrodes into the attacker’s body and shocking them. A five second shock with the device will generally disable an attacker for from 5 to 15 minutes. There is no control over the voltage. The unit will deliver a shock as long as the trigger is held down.

Voltage(s): Output voltage across the electrodes is anywhere from 25,000 to 125,000 volts depending on the size of the units. The units are generally powered by 9-volt batteries.

Current(s): Output currents are about 30 ma (milliamps).

Frequency(ies): The frequencies of the delivered shock depends on the circuit used in the electronics of the unit.

Body Effect(s): Intense sensation and general muscular weakness. Once shocked a bottom will be unable to move for 5 to 15 minutes. There will also be soreness around the point of contact. Muscular contractions may be strong enough to crack bones.

Intensity: Severe and intense.

Psychological Aspects: There are no audible cues, but the sight of the weapon will be enough to cause fear. Tops using tasers will often only use them to threaten rather than to actually shock.

Caution(s): Extremely high voltages are involved here with potentially intense body damage. Avoid using on the chest due to the potential of cracked or broken ribs. If used for shocking during extremelly intense play scenes, the top should be prepared to render assistance to the bottom as necessary. Be especially careful where you point the unit if you don t intend to shock someone. Some jurisdictions allow tasers only in the hands of law enforcement agencies. You need to check your local laws before getting one.

Toy: Telephone Magnetos

Operating Principle: A telephone magneto was used in old hand-cranked telephones to ring a bell at the operator’s switchboard. It has the mystique of being the classic torture device of military interrogators and South American dictators.

Voltage(s): Output voltage varies on how fast you crank the handle. You can get up to 100 volts AC.

Current(s): Depends on the voltage and the skin resistance, but you can easily get 10 ma (milliamps).

Frequency (ies): Depends on how fast you can crank the handle. Generally you generate around 25 Hz (Hertz).

Body Effect(s): The currents generated are generally enough to cause involuntary muscle flexures. When used over a long period of time, can cause muscle damage and deterioration.

Intensity: Severe sensory nerve sensations as well as intense muscle jumping.

Psychological Aspects: When done in the context of an interrogation torture scene, the mere sight of the device usually raises the bottom’s anxiety level. Also, in scenes where telephone magnetos are used, the bottom is generally restrained and has a feeling of helplessness when tortured with the device.

Caution(s): Telephone magnetos can be found in antique shops and flea markets, but are generally not in working condition. Very often the problem is an electrical wire break in the magneto. This is difficult to repair A telephone magneto is a heavy-duty toy A top using the it should be aware of potential muscle movement, and should only be used on large muscle masses like the buttocks, the thigh muscles, or the soles of the feet. Do not use telephone magnetos in orifices because of the voltages involved. Also, the chest and nipples should be avoided due to the potential of cracked or broken ribs and possible heart problems. Special care should be exercised in using telephone magnetos on the feet as the strong muscle flexures may be enough to break the small bores in the feet and ankles.

Toy: Household AC (from a wall outlet).

Operating Principle: I‘ve written many words in this book about how dangerous household AC is and how engineers and electrical codes design for and regulate it for reasons of safety. Yet some people insist on using it as a play toy.

There is a reported case of where a couple wanting to enhance their sex life inserted anal probes which were connected to the wires of a plugged in extension cord. One of them had the hot wire in their asshole; the other the neutral. They then fucked. Their corpses could not reveal whether there was even a momentary thrill in it.

Caution(s): For God s sake DO NOT USE THIS AS A PLAY TOY!

Toy: Automobile spark plug ignition system

Operating Principle: All gasoline-burning automobiles, whether they’re fuel injected or not, use a spark plug system for igniting the fuel in the cylinders. As part of the ignition system there is a transformer-like device called a coif that is used to generate extremely high voltages so that the spark plug can fire. There have been popular entertainment movies that show the good guy being tortured by being connected to one of the spark plug wires. As the motor revs up, the good guy screams in pain as this high voltage shocks him. Fortunately this is only a movie and the actor doesn’t really get shocked, but this method has been used during some interrogation tortures. I won’t even list the characteristics of this toy. It is simply too dangerous.

Caution(s): DO NOT USE THIS AS A PLAY TOY!

Toy: Neon Sign Transformer

Operating Principle: A high-voltage 60 Hz device which can be deadly if you make contact with its metal electrodes.

Caution(s): DO NOT USE THIS AS A PLAY TOY – even if it s marked “current-limited.”

Toy: Amateur Radio Transmitters used as Diathermy Machines

Operating Principle: Since a diathermy machine is basically a radio transmitter, some people are tempted to adapt a surplus radio transmitter to operate at the same frequencies as one. Because of the extreme risk of deep, painful, and slow-healing radio frequency burns, I won’t even fist the characteristics of doing this. It is simply too dangerous.

Caution(s): DO NOT USE AMATEUR RADIO TRANSMITTERS AS PLAY TOYS!

Toy: Diathermy Machine

Operating Principle: Doctors and physical therapists use diathermy machines to warm the interior tissues of a patient’s body for the relief of arthritic pain and muscle soreness. It is basically a radio transmitter operating at low radio frequencies, By use of properly positioned and operating antennae and grounding pads, the radio waves pass through the body and warm up the tissues as described in Chapters 6 and 11. A number of controls on the machine can adjust the radio wave strength, the frequency, the duration and many other factors. In the hands of a skilled operator, it can be quite therapeutic.

Voltage(s): Low output voltages of the radio signal. The voltages aren’t however, the key to the machine’s operation; the frequency is. The machine is powered from a wall outlet (120 volts AC)

Current(s): Low currents of the radio frequency signal flow inside the body. Generally less than 1 µa (microamp).

Frequency (ies): Diathermy machines operate at the low radio frequencies – generally between 50,000 to 200,000 Hz (Hertz).

Body Effect(s): Warming of the interior tissues by radio waves. (See Chapters 6 and 11).

Intensity: Generally mild warming sensations.

Psychological Aspects: The presence of a large, complicated machine can intimidate a bottom who is not familiar with diathermy machines. This intimidation can be enhanced when the bottom is restrained. When a bottom is blindfolded the feeling of tissue warming with nothing contacting the skin can either be pleasurable or worrisome to them.

Caution(s): These machines are rarely usedbecause of lack of availability in the used medical equipment market. If you can get a used one it should be carefully inspected and tested as it may be damaged. An apparently operating but yet damaged machine can be a source of radio interference (see Chapter 6). This can lead to an investigation and prosecution by the FCC. Also care must be exercised in the use of the antenna and grounding pads as there is the potential for inflicting deep, painful, and slow-healing burns inside the body. You should get the operating manuals with the machine and become thoroughly familiar with them.
