At around the same point in time, a researching urologist found that minute amounts of electrical current applied at a specific frequency combination to the base of the scrotum could stimulate the penis to erection.  And there are bountiful financial rewards for developments in the sex industry and all its by-products, as the Pfizer Corporation will confirm!   Following a gestation period of less than twelve months the first model of the Electronically Regulated Owen-coulomb Stimulator - EROS - was unveiled to the world.  This initial design was basic, comprising of a hollow thin ring of hardened Teflon in which was fitted an electromagnetic switch, an Owen-coulomb cell and frequency generator. Manufactured in two halves, it clipped together to fit snugly around the scrotum.  These early prototypes were operated with a manual key and, to prevent priapismic damage, the electrical stimulant ceased after a maximum of two hours. As an alternative to the outrageously expensive Viagra tablets and their clones, it was an instant unqualified success.  Whilst operative, almost any man could guarantee achieving and maintaining a firm erection within moments of switching on.

Further research, revealed that the opposite could also apply, and a different combination of frequencies ensured that the penis remained flaccid whatever the environmental stimuli.   This proved useful for the Corrections Dept who commissioned a model suitable for parole applicants convicted of sex offences. The outer skin was made from thin but impregnable titanium. It contained a rechargeable Owen-coulomb cell, a frequency generator, microprocessor and a radio-controlled receiver. The receiver responds to a remote transmitter that can adjust the settings and unlocks the device when the offender has been deemed to have completed his sentence. These rings are semi permanent and, at the instigation of women’s groups, designed so that any attempt at unauthorised removal results in a high discharge that, in effect, castrates the wearer.  Furthermore, when the level of charge decreases to a determined value, short sharp and increasingly painful shocks force the wearer to renew the cell charge. This is only required once every six months or so.

It was inevitable that an advanced version was soon on the general market that included a frequency generator that could achieve both effects, thus remotely fully controlling the sexual performance of the wearer. It was known as the EROS – C.  .  The result was to rent a tear in the social fabric of society by revolutionising the protocols of sexual etiquette. Within a remarkably short time,  tens of thousands of males were relegated to the level of sexual serfdom by their female partners.

The real geniuses of the EROS were the marketing pundits.  By the close of the first year of release,  it was 'chic' to wear such a ring.  Of course those men with an erectile dysfunction were keen to promote the device in a positive way. And research indicates that by the age of fifty nearly 40% of all males will experience erectile dysfunction of some form, at some time.  The design that could lead to castration was initially unavailable to the general market, being replaced by one able to inflict only a mild degree pain. But soon there were imports capable of the real thing the EROS –C+.  And, such being the urge to live on the sexual edge, it proved popular.  Girls hungered for the power it gave them, and were soon demanding of naïve and lusting boys, “if you really love me you will…” And so forth.

When Boyce was unfaithful to Kathleen, for the fifth time,  the survival of their marriage hung in the balance.  Yet his love for her was quite genuine. His ace card was that he knew Kathleen adored him. Their sex life was good, for they were both sexually adventurous, with imaginative innovation and, Boyce had an infallible ability to pace Kathleen to her orgasm.  As a breadwinner, he didn't resent Kathleen's much higher salary for he enjoyed his role as a social services supervisor.  His sensitivity was a complement to Kathleen's stoic lawyer's pragmatism.  But there is a limit to everyone's patience.  And Boyce had finally stretched Kathleen's to that limit.

His latest infidelity – Krystal - had blabbed the whole sordid details to her friends.  And with the affair on the public circuit it was only a matter of time before a sympathetic confidant would feel it was only right and proper that Kathleen was 'put in the picture'. 

So, when Boyce returned home that evening it was like stepping into a freezer.  Kathleen sat at the dining room table, her almond eyes narrow and her normally full red lips a thin angry gash.  She tapped her index finger on the polished mahogany surface.  Without a word, Boyce uneasily eased himself down into a chair opposite. Oh God, he thought, she knew about Krystal!

Try as hard as he might,  Boyce couldn’t hold his wife’s glacial stare. As he dropped his eyes,  she muttered sadly, "I'm sorry Boyce.  No more." 

She was not tall but maintained a steely strength of presence. She had short auburn hair, cut in a mannequin style - efficient to maintain.  Her figure was generous without being plump.  Her royal blue business suits cried out - crisp uniform.  That evening she'd obviously already showered, and changed into an above knee length cotton tan skirt and a traditional embroidered white silk blouse. A thick black ribbon with an Italian cameo about her throat promoted a Victorian demeanour.

Boyce continued to hold his silence. If his suspicions were correct, she would have sufficient evidence to overwhelm him as a defendant.  He adhered to the well known maxim, ‘if you find yourself in a hole, don’t dig’….   He bit his lip, and studied his clutched hands, his thoughts in turmoil.

"No more apologies Boyce."  She said, shaking her head.  Then she crossed her legs and Boyce was startled by a glimpse of stocking top!  Stockings were their intimate signal that usually indicated the promise of sex, and although suddenly confused, he couldn’t avoid a tightness in his stomach.  This didn’t make sense? Maybe….  “I don’t understand.” He mumbled, hopefully.

“Krystal.”  She snapped, sending his hopes plummeting.

"I, I er, I couldn’t help it."  He said quickly, grimacing at the terrible cliché.  "I’ve no excuses,  I…” He fumbled, adding quickly, “I'd do anything for you, you know that… Anything."

Kathleen raised her hand for him to stop and shussed .   She idly picked a stray hair off the arm of her blouse, before returning her laser gaze at him.  In fact, she was not entirely unsympathetic. He was very good-looking and would always have temptations put into his path.  "Actually Boyce,  I really do think you can't help it." She said resignedly. “So, where do we go from here?”

"I don't know what to say."  His shoulders lifted fractionally.

She nodded slowly, paused, then, asked coyly, "Do you mean it?"

"What?"  He frowned.

"Anything?  You'd do anything to keep our marriage alive?"

"Yes. I give you my word." A glimmer of hope flickered within.

There was a moment of silence, before she said in a measured tone. "All right."  Boyce’s eyebrows rose questioningly. Kathleen studied him carefully, pursed her lips, and said slowly. "I want you to wear an EROS." 

Boyce's eyes flicked from side to side.  "But…" He paused, forehead creasing. "But I have one, what do I need with another?” Shrugging. “As if I needed one anyway." 

"Ah, you fail to grasp the point. You only have a stimulant,  I want you wearing one with an ECD option, an EROS – C+” Adding pointedly.  “Permanently, with me having control of the transmitter." 

She uncrossed her legs and folded her arms across her chest.  By slightly leaning back he could see up her skirt to the white of her thighs.   His groin gave a familiar stir as common sense ebbed away. 

"It's that, or divorce."  She added with finality. An ultimatum.  

Boyce tried to grasp the implications.  It was not lost on him that he would be handing over total control of his libido to his wife. Not that Boyce was entirely against the idea, for the idea of wearing an Enforced Chastity Device intrigued him - especially in his current state of mounting lust.  He was also aware that with most of the devices, once fitted, only the person with the transmitter could ever remove it without incurring dire consequences to the wearer.

"Yes,  I meant anything."  His ache for her was becoming intense, he breathed quickly, his organ hardening. "But…” he started.

“No buts…”  Kathleen snapped.

“Well, I…”

“For heaven’s sake Boyce, no buts!”  She repeated, raising her voice.  She shifted slightly and her skirt rose such that a generous expanse of white thigh was exposed.

Boyce caught his breath and his pulse quickened. His negotiating position was weak, futile in fact and speedy submission might help to mitigate his marital transgression.  “Of course, for you, I'll wear one."  He said, his usually disarming smile lacking substance.

Kathleen straightened.  "I thought you might concur."  She said, and reached into a black leather bag under her seat, extracting a small package.  She carefully removed the wrapping and displayed a silver ring with an accompanying small plastic device resembling a car remote control.  "Now is as good a time as any to fit it."  She said.  At his look of astonishment she sighed. "Boyce, you really are predictable aren't you." 

She again crossed her legs and her skirt rose continued its ascent. Boyce swallowed.  She nodded towards his groin and he obediently rose. He slowly undid his belt, unzipped his jeans, slid them down and stepped clear. He felt foolish still wearing socks so he tossed them aside, followed by his shirt, and boxer shorts.  He stood meekly before her, as naked as Adam.  She raised an eyebrow at his erection.  She hooked her index finger and beckoned him forward.  She cupped his testicles and encircled his scrotum with the opened ring. Then she clipped it shut.  Boyce was amazed to see his erection collapse within seconds. Kathleen grinned, "think of that as my wedding ring to you." She said, adding sweetly. "A very effective one I think, don’t you?"

 Kathleen held up the small transmitter, which she carefully attached to her key ring.

"Now Boyce."  She said, with a slow smile of satisfaction.  "Whilst in the default setting you cannot gain an erection, you will virtually be a eunuch.  Only when I initiate this setting",  and she pressed a combination of buttons,  "will you achieve an erection."  Sure enough, Boyce's penis started to harden.  She leaned back and he blinked as she inched her skirt up around her waist. She splayed her legs. The dark stockings,  black suspenders, the contrasting cream flesh and the mound under her maroon net panties drew him like a dog to a bone. 

With a whimper he dropped to his knees before her, his erection as hard as he'd ever known it.   "I don't need that for this…"  He grunted, thrusting his groin forward.

"Nor do I need that…” She pouted, “for this…"  And, stroking herself, she pressed another combination of buttons.  Despite his raging desire his penis suddenly lost its hardness and began to droop.  "Instant castration."  She observed.  Then, she arched her back and wriggled out of her panties.  "Tongue time only." She commanded reopening her shapely legs. 

Boyce hesitated, fascinated by his shrinking penis.  Kathleen jabbed another button and a sharp spasm of pain shot through his testicles.  He yelped. "Now!" She snapped.  He dutifully lunged forward, putting his lips to her moist warm smooth womanhood, and his tongue energetically flicked in and out. 

He was good she had to admit.

Her breath came in short diminutive gasps, evolving to slow deep drawn out gulps of air until she finally began to groan in orgasmic ecstasy.  She would have enjoyed feeling his hardness penetrate her,  but this was the time for training him.  His tongue revolved, lapped, searched, and tickled at her clitoris. Kathleen squirmed, her legs widening almost to the point of pain. She thrust her pelvis at him and he opened his mouth to engulf her entire mound of Venus.  Finally she gave a resounding squeal of pleasure and slumped back, panting, her tongue playing across her lips.

She almost purred.  "Good boy Boyce."   She said, pressing her skirt back down.  "Now, only I know the correct sequence of buttons to press."  She paused to let that sink in before going on.  "If you get hold of this device and happen to press the wrong button combination, you are likely to painfully castrate yourself.  It's a Korean model and these devices are not regulated in that country. Anything goes, including your testicles, if you misbehave.  Try to have the device removed and the same thing will happen."  She stood, towering above him.  "Your whole sexual existence is now mine Boyce. Emasculated when I want you to be and a stud when it suits only me. No more women on the side for you”. She growled in self satisfaction. Dropping her voice a little she said huskily, “Oh, and I think I should tell you that the little twinge of pain you just received was on the lowest setting. Bear that in mind….”

"What about when I want to relieve myself, that is sexually?"  He asked with growing unease.

Katherine shrugged.  "Only with my express permission."  She replied, studying her nails.  "And you'll have to prove yourself very good before I give you that." She tossed her head.  "Don't worry, our relationship will be perfectly normal other than in the sex department, where you'll learn to serve and adore me as your only desire."  She pressed a button and his organ, like a rearing cobra, again dutifully rose to the occasion.

He slowly stroked it with mounting fervour.  "Oh, Kathleen, thankyou."  He whispered, the speed of his hand steadily increasing. 

"Stop!"  She snapped.  He instantly ceased and looked at her with pleading spaniel eyes.

"You didn’t ask!  If you wish to relieve yourself you ask my permission, and it will only be given on very special occasions…" 

"But,  but…"  He started and she cut him short.  “I warned you Boyce – no buts.  Only when you are very well behaved, indeed fully trained…"   Kathleen left the rest unsaid. She had been given some advice on the training of her man.  Her control over him lay between his legs.  When excited he would be her slave, desperate for sexual relief.  When, in his neutered state, the desire was lessened her power would diminish.

Her friend Jacqueline had put it most succinctly.  "Kathleen,   ‘when men’s balls are full their brain is empty’. " She had gone on to advise. "Keep the beast gagging for you, effectively lead him on by his erection."  Adding darkly,  "and if he misbehaves,  introduce a little pain… As the saying goes, don’t spare the rod…."  She thought for a moment then said.  “Oh, and demonstrate the power you hold over him to your friends. They’ll no doubt guess the reason and it will deter their attempts to attract him. Or maybe prove a challenge?”  They both laughed.  “And don’t rely solely on your EROS. Let him have a taste of the cane, or whatever you prefer. Part of the training is for him to submit voluntarily to discipline. Get him used to obeying you, and offering his bare backside to you even when he knows it will entail a painful retribution. And don’t forget the carrot… Give him his treats and believe me,  you’ll soon have him eating out of your hand.”

Kathleen pressed a sequence of buttons.  Boyce looked down in disappointment at his deflating erection. 

Kathleen popped her key ring into her handbag.  "Maybe tomorrow."  She hinted mischievously.   "Oh, by the way Boyce.."  She turned to him on her way out. "Do you remember Carla?"  Boyce frowned.  She put her head to one side. "That new social worker you upset?”

Boyce nodded warily.  Carla Fleming had been late several times,  and had run up an official telephone bill with private calls.  He'd had to call her into his office and reprimand her. She was a cheeky damn cat. Insubordinate to the extreme, and he'd berated her in front of her two colleagues. If looks could kill he'd have been struck down instantly.  She was hard, vindictive as well, not really suited to the sensitive environment of his workplace.  Her small cobalt eyes,  trim blonde hair cut boy's style, and slim figure made her look almost masculine. He wondered about her sexual orientation?  A dyke if ever there was one, he thought sulkily.

Kathleen smiled, her eyes hooded. "Well you see Boyce,  you haven't yet been punished for being unfaithful to me, have you? Today was about the future, not the past." 

Boyce's brow furrowed. 

"Tomorrow Boyce, I'm going to loan this to Carla. Don’t worry, it’s only for an hour or so…. I'm sure she’ll think of an appropriate redress. …"  And she swirled out of the room.

Boyce swallowed, whilst Carla held the transmitter he'd be entirely at her mercy.  His face slowly drained ashen white.  In those circumstances, an hour or so could be a very, very long time…
