Amy’s long legs strutted back and forth, their length amplified by high heels, red lace panties and nothing in between. She wore a pink woollen cardigan which was falling open to reveal her bare breasts, but that was of less consequence to her friends.

Ben and Louisa were sitting on the floor beneath her, watching silently as her stiletto heels snapped down inches from their bodies. Both were naked other than for their chastity devices. Louisa’s steel belt clinched taut around her waist, nestled deep between her cheeks, and clamped down hard over her clit and vagina. As all the time, Ben was locked away inside his metal chastity cage which looped pitilessly through his Prince Albert piercing.

“Amy, I don’t think I can do this,” Louisa whispered.

Amy stopped and turned to invite Louisa to kiss her round, pert butt. Louisa trembled audibly as her lips touched Amy’s smooth bare skin and then slid deeper, following the delicate red lace lingerie that disappeared between Amy’s cheeks.

“I told you the rules,” Amy breathed.

“I thought you were joking?” Louisa stuttered.

Amy took a step back, pressing her bottom against Louisa’s face. The nose could build such a beautiful tingle, “Do you want to challenge my rules?”

Louisa didn’t answer but pressed her face deeper into Amy’s bottom, kissing the delicate lace that would spend the day inside Amy’s deep intimate cave.

Amy had had to pinch herself every day. The rush of power from holding Ben’s chastity key was a constant thrill, only amplified by the look in his adoring eyes. Some people achieved confidence through sport or their professional life, but for Amy, confidence came through denying someone access to sexual pleasure. Such a basic human need and one, when taken away, that could bring total devotion from those locked away.

She pinched herself again. She would never have been able to pose this confidently in front of others. It was the kind of thing she had done in private, a new pair of shoes, her favourite panties, and a mirror. It would lead to time alone with her vibrator living out fantasies before her panties had to be placed in the laundry basket.

Now she could perform and be her natural dominant self in front of both of her best friends. She didn’t even need to say anything, no chastity jail sentence had passed her red painted lips. Ben and Louisa both knew that red lingerie meant a month locked in constant chastity. Yes, her friends wanted to distribute the smouldering look in her big brown eyes, but they also wanted to press intimate kisses on her body as she paraded back and forth. It was as if the delicate lace lingerie itself had condemned them to sexual slavery.

Amy felt happy and confident to do something she hardly ever did. She clipped over to her high security safe that required her key, her fingerprint and her twelve-digit code to open. Inside was a worn silk negligee, the first present Ben had ever bought her, and wrapped up inside that were two keys.

Amy took the keys and pressed them against her chest. She then threaded them both on to a thin silver chain which she clipped closed around her neck. These were the only keys to her friends’ high security chastity devices; their twins having been clipped into many small pieces by Amy’s hand and an unforgiving pair of pliers.

She stared in the mirror, her fingers playing with the two shiny keys as she critically assessed how they looked between her pert, but modest bare breasts. She pulled her pink cardigan tighter and buttoned it up. She liked how that made her breasts look bigger, more luscious while the key still dangled in plain sight.

“Wow is that…?” Ben exclaimed; it had been ages since he’d seen his key.

“Maybe,” Amy replied bashfully.

Both of her friends were craning their gaze upwards while still sitting on the floor in an unspoken deference to the woman who controlled their orgasms.

“But we could just take them?” Louisa blurted her thoughts out loud.

“Do you want to?” Amy asked.

Louisa shook her head creating waves of blonde hair usually intended to entice men. Her belt may have been designed to stop all pleasure, but right now it was doing the opposite. Everything was so tight that her butt tingled from the steel and the front plate clamped down trapping her vagina in constant arousal. A sensation amplified by the fact that escape was completely impossible.

“Good girl,” Amy whispered, “If you were to try anything…” she paused for dramatic effect, “Then I’ll leave you locked forever.”

Louisa swallowed with excitement, her mouth dry and her body alight.

“Bad girls who disobey red panties spend their whole lives in chastity,” Amy whispered, the conversation evidently arousing Louisa who was now hugging Amy’s leg, “They wake up in chains and cuffs with my panties stuffed in their mouth.

“Stop it, it’s too nice!” Louisa cried, her hands clutching at her belt.

Ben was also feeling the effects of both Amy’s provocative words and the sight of his key swishing back and forth between Amy’s breasts.

“You can get up, you know,” Amy giggled.

Ben and Louisa climbed gingerly to their feet still unsure what to do.

“I own your genitals,” Amy called casually, “but otherwise you’re free to go.”

An hour later and Amy reappeared from their bedroom, braless and wearing a black sheer see-through top and jeans. The black mesh material was tight and did little to hide either her breasts or the keys nestled in their dreamy blurry underworld beneath. The top was blatantly sexual and had been on and off Amy’s body many times in the privacy of her bedroom, but this was the first time that Amy had felt assertive enough to wear it in public.

“Wow!” Ben blurted, clearly impressed.

Amy then pulled on her tight faux black leather jacket and pulled the zip halfway up. The keys were still visible, but only just as the jacket stretched around her body, pressing her breasts together with the keys caught in between.

“What?” Amy blurted in response to their stunned looks, “If I lose the keys, you’re both fucked.”

“My cage has just got smaller,” Ben mouthed.

Amy grinned at his flattery and pushed Ben back on to the couch and knelt astride his waist to kiss him. Ben’s hands were shaking as he squeezed her denim cover butt.

“Too sexy,” he panted, “You sure your panties are still red?”

“Want me to show you?”

“No!” he cried.

Amy climbed off his lap just as Louisa appeared from the spare room wearing a white crop top and short green ra ra skirt. The chastity belt’s tight steel waist band was visible above the skirt’s waistline as well as the front plate and back piece clearly plunging down to lock up everything beneath.

“So sexy but in public?” Louisa asked.

“Why not? I’m wearing your key in public,” Amy whispered.

Amy pressed her body against Louisa’s and kissed her lips, mouthing her words slowly, “Do I need to remind you how fucked you would be if your key were to stay between my breasts for ever?”

Louisa was almost hidden behind her freshly brushed blonde hair as she fervently kissed her keyholder.

“I could lock you back in the steel head mask,” Amy whispered, “Turn the dials on the combination padlock one by one… maybe I won’t let you out this time.”

Louisa was trembling. That was exactly how she had spent the previous night, trapped in sensory deprivation in a steel mask to which only Amy had the combination.

“Okay, I’ll wear the skirt,” Louisa mouthed, slipping on her jacket which did little to hide her belt.

Amy reached into the pocket of her shiny leather jacket and pulled out the small device that controlled the electric shocker for Ben’s chastity cage. Once activated, Ben could be no more than three meters away without writhing in agony as electric current pulsed through his cock.

“In public?” Ben asked.

Amy nodded as she unbuttoned her tight blue hip-hugging jeans and tucked the slim device inside the crouch of the infamous red panties. She peered down inside, fumbling with herself until she found the button to power it up and pair her with Ben’s cage.

“I hope you’re not thinking of leaving me?” Amy smiled, her insecurities coming through despite the cruelly tight leash on which she now had her lover. She buttoned herself back into her high waisted jeans so that all trace of the torture device was hidden within her curves.

*

Amy had a permanent smile on her face as the three friends walked into town. Ben’s strong hands hadn’t once let her go. His hands had wondered down on to her butt and he had even stopped her to kiss while his hands caressed her breasts.

“Opps!” Amy teased as they sat down at a table at the back of the café. She opened her legs and traced the controller through her jeans, “I heard a crack… I hope it’s alright.”

Ben looked concerned which made Amy laugh, “I’m joking sweetie.”

Meanwhile, Louisa was still mesmerized by Amy’s breasts that were blatantly on display.

“I want it even more when I can see it,” Louisa whispered, unclear whether she meant Amy’s breasts or the keys. She had always been bi-curious, but Amy’s bare breasts and erect nipples were taking on an almost obsessive attraction.

“Don’t encourage her Lou or her dampness will set off an electric shock,” Ben replied.

“Hey!” Amy giggled.

Amy unbuttoned her jeans and delved down into her warm lingerie for the controller. She provocatively wiped it on a serviette before placing it on her chair and sitting down on top. Ben was about to protest when Amy started to bounce, her bottom crushing down on the wholly inadequate plastic device.

Amy’s jeans were tight on her thighs and formed creases as they hugged her hips, curving up to be secured around her slim waist by a thick brown belt. The snugly enclosing denim felt gorgeous, the seam toying with her as she pulsed her hips forward. The small device creaked under her weight.

Every time Ben looked at her, Amy smiled back, almost challenging him to rescue the device that was being tortured beneath her rocking hips. For a slim woman, Amy’s toned butt had a reputation for causing havoc. As well as regular poundings to Ben’s cock and his face, she had once managed to bend the only key for Ben’s handcuffs. He had had to sleep in them all night before Amy’s stamping heels had been able to pummel it back into shape.

As a rule, Ben didn’t like shopping, but helping Amy choose beachwear was an exception. He chose a chair very close to Amy’s fitting room and waited for her to appear.

Inside, Amy pulled off her boots and eased out of her jeans. She pulled on the bikini and turned slowly in the mirror, trying to judge whether Ben would approve. Despite spending much of her life as his cruel mistress, she was constantly desperate for his approval. Having tried on several pairs, she finally reappeared in a high black cut bikini.

“What do you think?” she asked.

Amy always did a little dance when trying on bikinis as if checking how it would look during a beach party. Ben inspected the taut black bikini top that drew tightly over her chest, pinching her breasts together with the keys almost consumed within., “Stunning,” he rasped, clutching his cage.

“Perfect, it works!” Amy giggled.

Amy took her time trying on more bikinis, enjoying the opportunity to undress in the privacy of the fitting room, catching a glimpse of Ben’s chastity key in the mirror as she posed.

With several pairs chosen, she hustled back into her jeans and tightened the belt with the controller still inside. She grinned innocently at Ben. His blue shirt looked gorgeous, moulding around his chest with several buttons undone and the cuffs also unbuttoned to give a chilled vibe that matched both his short dark ruffled hair and her mood.

Outvoted again, Ben next followed the women into the lingerie store. Amy held up a deep red bra and panties and giggled as both Ben and Louisa clambered to pull if from her hands.

“Your underwear has already condemned me to a month in sexual incarceration,” Louisa whispered.

Louisa picked up a pair of white silk lingerie and ran her fingers over the soft fabric.

“Somewhat hopeful Lou?” Amy smiled.

Louisa smiled alluring, it worked with men, “Maybe when’s Ben’s asleep?” she whispered, “You and me?”

Louisa traced her nails over Amy’s mesh top, her blatant breasts moving with her touch and pressing against the dangling keys. Louisa sighed longingly, her fingers brushing against the keys that were trapped beneath the see-though mesh as if in jail.

“You’ll not gonna let me out, are you?” Louisa sighed.

“No, sweetie”

Ben followed the women obediently and was still in touching distance of his keyholder when an electric shock sparked through his cock, “Fuck!” he mouthed. He stepped closer to Amy only to be shocked again.

“Where’s the controller?” he panted.

Amy kissed him, giggled and walked off to the negligees.

Fuck. There were hundreds of bras and hundred more panties within range and Amy could have hidden the small controller in any of them. As discretely as a man could be in a lingerie department, he started to seach one by one.

“Anything you’re looking for in particular?”

He turned to see a young smiling shop assistant in the ubiquitous white blouse and black skirt. She seemed delighted to help a tall, attractive male customer and had already selected matching blue satin bra and knickers.

“I love this cut and material,” she smiled, “I’m actually wearing this one right now.”

Ben couldn’t help it, his imagination had already slipped inside her uniform and his cock twitched and swelled in its cage as the assistant turned and searched through more of her stock.

“What’s this?” the shop assistant called, holding the controller in her hand, “Jess, do you know what this is?” she called walking off towards her supervisor.

Ben dropped to his knees as electricity shoot through this penis. Fortunately, the shop assistant heard him and swung her hips and darted back to check on her customer, “Are you okay?”

“My knee… football injury,” Ben panted, “Fine now.”

The woman stepped closer and brushed her hand through his short dark hair, “Look, I wasn’t lying,” she flirted, lifting her skirt to show him the very same blue satin lingerie.

Ben had to act quickly before the woman unwittingly caused him excruciating pain. Seeing the small controlled in her closed fist, he pulled her closer, kissed her thigh and glided his up towards her lingerie. The woman cried out in surprise and stumbled backwards into a rail of bras. She composed herself and smiled as Ben kissed her and then walked away with the controller safely in his hand.

Ben cornered Amy by the nightwear and pressed her up against the wall. He loosened her jeans and pushed his hand inside.

“I believe this is yours,” he whispered, easing the small plastic device back into is warm home.

“Silly me,” she giggled.

Ben buttoned her up, overtightening her thick brown belt until the denim seam constricted between her cheeks. It wasn’t unusual for Amy to have a padlock in her jacket pocket and Ben retrieved it and used it to lock her overtightened belt in place. He then squeezed the key inside her tight waistband from where it dropped and landed on the controller in the crotch of her red panties.

“Just in case you mislay it,” Ben whispered.

Amy had had a gorgeous day of shopping and Ben had just sat through a long and flirtatious fashion show. Louisa was already asleep, she had actually asked to be locked away in the spare room, in part due to the constant torment of Amy’s bare breasts.

Ben kissed Amy’s lips and then ventured down to kiss her nipples. The keys were gone, they were back in Amy’s safe. He closed his eyes before going deeper. Amy’s legs had already opened, anticipating his touch.

“Oh fuck, I want you!” Ben cries, his body on fire despite the crushing pressure in his one-inch long cage.

“It’s okay,” Amy whispered, grinding his head against her crotch, while subtly pulling her lingerie to the side. He kissed her, soft lips against her skin and then his tongue fused with her vagina. Flicking, licking and twirling, he slowly brought her to a powerful orgasm.

Ben rolled back on to the bed with a smile on his gasping lip, “Wow, yeah!”

“You do realise that it was me that climaxed?”

“Amy, you’re denying me for a month,” Ben’s eyes were closed as he tickled his own balls, “I’m just gonna live your orgasms instead.”

He rolled over and groaned as Amy’s breast bounced against his face, “Cover up darling or I’ll never get to sleep.”

Amy rolled out of bed but instead of a nightie, she returned with the steel head mask.

“Why don’t you cover up?” she purred.

Ben’s mischievous twitching cock was leading him astray again. Within seconds, Amy had closed the heavy steel mask around his head.

“No, wait. Your breasts were the last thing I saw,” he called, muffled laughter echoing in the mask.

But Amy was now sitting on the ball mask with her legs gripping it tightly, “Pity,” she laughed as the padlock clicked shut.
