Amy had succumbed yet again, letting Ben out of chastity so that they could make love. However, this time she had placed a thin layer of textured steel mesh inside his small Prince Albert chastity cage before locking it back on his ever-hopeful cock. Now when Ben’s cock swelled, it pushed into the mesh causing a whole new feeling of sadistic pain.

They had redressed after love making, Ben in jeans and a black shirt, and Amy in her short red dress, and were sitting opposite each other on the kitchen stools.

“I’m nervous and I’m not even wearing the cage,” Amy smiled excitedly, her body glowing from intercourse and now eager to understand the new look in Ben’s dreamy eyes.

“It’s cool,” he breathed hesitantly.

“You know what I’ll do it you misbehave…,” Amy paused as she brushed her fingers over her crossed legs. The thin sheer material of her dress moved with her, revealing her toned thighs and pale flowery lingerie, “…I’ll undress.”

“Oh fuck,” Ben moaned, his penis starting to burn, “That might kill me.”

Amy pulled her dress back down so that it covered her thighs and watched Ben’s eyes intently, “Shall I remove the mesh?” she asked apprehensively.

Ben gazed at Amy as she fidgeted nervously. The new sensation inside his cage, and the potential of much more to come, only added to her power and mystique. This could hurt, but right then being hurt by such beautiful eyes was enticing. “Coffee?” he smiled.

*

They left their apartment and walked together, Amy hidden behind sunglasses and a wide-brimmed hat. When they reached the café, Amy handed her designer leather jacket to the waitress and let Ben lead her to their usual table at the back.

“I hope you don’t try to have an erection here,” she smiled mischievously.

“At least you have the key… in case of emergency,” Ben winked.

“Oh, but you can’t have it…” Amy leaned forward, licking her lips as she spoke.

“I’ll take it by force, if I have to…”

“You know where I keep it, “Amy breathed as she uncrossed her legs, “I’ll have you arrested before you get anywhere near it.”

The pretty brunette beneath the wide brim of her summer hat was again controlling his cock, her eyes and her smile making him swell uncontrollably, “I guess I’ll just collapse in agony on the floor by your feet?”

“Guess you do…”

Amy could feel the mix of power and arousal going to her head. Their lips were almost touching, and she could feel Ben’s rapid breathe. He was about to kiss her when he broke away, stood up and looked round the room in an effort to clear his mind.

“I may as well collapse by your feet now,” he smiled painfully.

“Please do…”

Ben looked under the table at Amy’s ankle-high leather boots and long legs that disappeared under her hitched-up red dress.

“Unless you want to look for the key with your lips…” she sighed dreamily.

“That would probably castrate me,” Ben replied.

Amy smiled and beckoned with her fingers for Ben to pass her the chain that was padlocked to his chastity cage.

“Really?” he asked, the swelling already starting, “Here?”

“Aha…”

Amy discretely reached beneath the table for the chain and wrapped it around the metal bar that was embedded in the wall and locked it with a padlock.

“At least that won’t stop me from collapsing at your feet,” Ben breathed, “… in fact now that’s about all I can do.”

‘Mind and body,” Amy purred. She made a cute clicking noise, “Imprisonment, humiliation, castration… mmm, what shall it be today?”

Ben loved watching Amy become aroused, it was such a turn-on, but this time painfully so.

“Let’s go home and make love,” he winced, her cage gripping and tormenting his cock.

“And let you go free?” Amy’s hand was under her dress, surreptitiously touching the silk that pulled tight around her love-struck body, “You don’t know how much I love this.”

“I do… that’s why it's agony.”

Amy was now tuning out as the feeling grew.

“Amy?” Ben called.

“We’ll make love at home…”

She stood up and stretched, her thighs revealing themselves from beneath the sheer red fabric.

“Amy, I’m chained to the wall,” Ben whispered, both his cock and his mind about to blow.

Amy slinked around to Ben’s side of the table and kissed his mouth, her tongue pushing deep, her body desperate for his, “The key to the chain is in my jacket… I’ll leave it for you,” she murmured, pointing to the coat rack that was way out of Ben’s reach.

“No!” he cried, “How do I get that?” His eyes were aroused and confused as his hand slipped hopefully beneath her dress, perilously close to her clit.

Amy stopped and looked at him carefully, “Never say ‘no’, darling…”

Ben smiled, totally captivated by her domineering beauty.

“I’m sorry,” he gasped, “Just that your cage is really gripping me.”

Amy leaned in and whispered, “Enjoy the torment, darling,” she trembled as she turned, her dress floating up almost magically as she left.

Ben watched her walk away, stopping only at the coat rack to slip her fitted leather jacket over her slim shoulders.

*

Once again, she had taken his breath away leaving Ben with flashbacks to when they had first met. Excitement mixed with pure terror, not knowing who she was or when she might unlock him. He watched her walk away with the same admiration, even reverence, that he had felt when she had been the unknown woman in the sex shop.

He watched her swish back her hair and stride towards a table at the far side café of the large crowded café. She spun around, smoothed her dress, and sat down to watch the man she had left chained by his penis to the wall.

His phone dinged with a text, ‘Love to watch you get out of this’.

Ben ordered another coffee and just sat watching Amy from across the room. She was smiling and playing with her hair but stayed frustratingly on her seat.

His phone dinged again, ‘You can leave at any time.’

‘Just without my penis!’ He caught her eye and they shared a smile, ‘Don’t smile, it hurts!’ he typed.

Amy giggled, picked up her bag and left.

*

She returned over an hour later and sat down on her original chair opposite Ben with her shopping bags piled next to her. His eyes seemed to follow her as if idolising her, which made her lips part and her breathing slow.  She placed a single key on the table between them and watched Ben’s reaction.

“That will unchain you from the wall…if you want,” she offered.

Ben touched the key, “It's warm.”

Amy smiled.

The padlock key was tiny and it seemed almost insulting that that one key in Amy’s pocket had been enough to imprison him. He looked around and discretely released the small padlock that tethered him to the wall. He coiled the chained back inside his pocket, picked up her shopping and quickly followed Amy outside.

The day was now hot, and a warm wind was tugging at Amy’s dress, the thin red fabric pulling tight and moulding itself to her body. She spun around as Ben approached her, letting the wind lift her dress even further. She was smiling, sexually alive, as she stood with her legs apart and her tongue hovering against her lips.

She then turned again and ran into the park, with Ben in pursuit. He caught her hand and reeled her in and kissed her. Her tongue dug into his mouth, sending shock waves into his body and seconds later pain into his mesh-covered chastity cage.

“Fucking mesh,” he moaned, now on his knees.

He traced his finger up Amy’s legs and felt his chastity key clipped to the inside of her pale flowery lingerie. It was low down, deep between her cheeks in what Amy had found to be the most intimately secure hidey-hole; completely hidden from sight.

“Maybe I should be wearing jeans,” Amy breathed.

Ben knew that was her way of saying that she wouldn’t unlock him. It was both her codeword and practical reality as there was no way to extract the key once she had squeezed her body into figure-hugging jeans.

“With the mesh still inside?” Ben gasped.

She nodded.

“I only felt the key through your pants.”

“Maybe I should lock you in your room while I change …” 

“I didn’t touch it,” he cried with arousal and frustration in equal measures.

He loved playing with Amy when she was in this mood and grabbed her around the waist and kissed her again. And yet again he had to stop as the mesh dug into his cock.

Another couple had just entered the park and so Ben wrapped his hand around Amy’s and tried to lead her away. She tried to hold him back, her dress swaying as she fought to resist. He pulled again and she wobbled off balance and laughed as she stepped forward only to be caught by his strong arms.

With Ben now in control, Amy unzipped his fly and reached for the chain that was attached to his cock cage and tugged gently. Ben stopped and stared back into Amy’s dark eyes, wondering where her slim tanned arms would take him. Instead, Amy wrapped her arms around his neck and thrust her body against his as she kissed his lips.

Ben’s cock swelled against the mesh and, with the pain building, he had to get away. However, Amy still held the leash to his cock, controlling him like most girls would control their dog. He crouched down to relieve the pressure just as a gust of wind whipped up her dress to reveal innocent flowery underwear.

“Before it's lost inside your jeans,” Ben panted, his lips stimulating Amy’s clit through her damp underwear.

“Oh fuck, don’t make me change my mind…” she moaned, desperate to indulge in more fantasies before they made love. She pulled up on the chain and forced Ben back onto his feet.

“Let’s go, darling,” she snapped as she tugged him forward.

Ben tried to protest, but Amy pulled on the chain to winch her helpless man towards her, his cage pushing harmlessly into her crotch. After only the briefest of kisses, she pulled him over to a nearby railing, half hidden by the trees, and wrapped the chain around the steel bars.

“Don’t chain me up again… it’s too fucking sexy!” Ben moaned.

Amy turned and walked a few steps before sitting down on the grass.

“How did you lock me up so quickly?” Ben called genuinely amazed.

Amy smiled from behind sunglasses as she lay in the sun with her legs apart and her dress riding higher and higher on her body.

“Okay, just put your jeans on,” Ben cried, now accepting that if Amy wasn’t ready to release him, then it was better if he couldn’t see what he was missing.

With Ben almost in touching distance of her spread legs, Amy closed her eyes and daydreamed. She imagined Ben breaking loose and dropping to his knees to worship her. It was amazing how she could almost feel his lips. She imagined him breaking out of his cage and forcing himself on her with the appetite of a man who had been denied for a hundred years. It was a beautiful fantasy and one that they would have to play out that evening. For now, she had an even better fantasy; her imprisoned and chastised man waiting lovingly for his release.

*

By the time they had returned home, and Ben had closed the front door, Amy was already in their bedroom, easing her jeans up over her thighs. Ben sighed, his cock aching from the mesh, now totally exasperated as her jeans disappeared up inside her dress. He watched as the denim squeezed over her round butt, stretched over her hips, and finally buttoned up around her waist. Only then did she slip out of her dress and pull on a white tee-shirt.

Amy was so close, her scent playing with his mind, and yet he had to block her smile from his thoughts or else suffer the consequences. He looked around the room but couldn’t help but glance back.

“I can’t even watch you,” he winced, tapping his crotch to relieve the discomfort.

“A real dilemma….”

“Make love?” he asked hopefully.

“Soon…”

“Can I swap places with the key?”

Amy smiled as Ben took her hand and led her over to the door of the spare room. He let go and walked inside alone and undressed down to his cage.

“Please lock me in and throw away the key,” he exhaled, everything about the brunette spinning around his head.

“Do you still like this?” she asked tentatively.

“I’ve never felt more alive.”

“You still pleased I moved in?”

“Fuck, there’s so much I want to do with you,” he sighed longingly.

“Does that include wearing my cuffs?”

Amy grinned, and her ponytail bobbed, as she cuffed Ben’s hands to his chastity cage and trailed her fingers longingly around his naked body. She then placed one hand on the silver door handle, “I promise it will only be for a little while?” she whispered almost remorsefully.

“Just lock me in,” Ben cried unable to look at her aroused body for a moment longer.

Amy pulled the door closed with a bang and turned the key. She had never felt so happy and so excited; a sort of excitement that she hadn’t felt since she was a child.

Ben stood and rattled the locked door. It was maddeningly frustrating, but this was what he loved about Amy. He paced around the small room to the security bars on the small windows and then returned and knelt back down to look at her.

“Would you ever throw away my chastity key?” he asked.

Amy looked back at him shyly through the empty keyhole, “That’s mine forever,” she whispered.

“And if you leave me?” he asked.

“Then I’ll take it with me…”

“I love you,” Ben breathed.

“I love you too…” she quickly repeated.

They stopped and stared. Neither had said those words before. Ben started to smile, which made Amy giggle.

“Is this your attempt to get an early release?” she asked accusingly.

“Would it work?”

“No!” she cried before pausing, “Okay, yes!”

Ben fell forward, and with his chained hands unable to stop him, head-butted the door. Amy laughed out loud as she jumped up and searched her pockets for the door key. Seconds later the door was open, and she stood almost timidly in front of him.

“Want to undress me?” she asked sweetly.

“Want to let me out of these chains?”

“Well, I can’t really do that until you’ve undressed me…” Amy tapped the back of her jeans.

Still handcuffed to his own balls, Ben unbuttoned her jeans and used his shackled hands to tussle and pull the denim down over her hips.

“Sure you can’t help?” he panted with a smile.

Amy shook her head, leaving her shackled man to slowly ease her jeans from her body. Her tee-shirt was impossible for Ben to remove and so he went straight to her panties. The silk quickly floated down to her ankles but stayed trapped as Amy refused to lift her feet. His penis was now throbbing, and he dropped to his knees and rolled down onto the floor and looked up the provocative woman above him.

“Okay, I’ve officially collapsed at your feet,” he laughed.

Amy retrieved the keys and released one of Ben’s handcuffs, only to lock the free end around her ankle. She unlocked his chastity cage and carefully removed the cage to reveal a red crisscrossed mesh pattern on Ben’s penis.

Ben lay still as blood rushed back into his tormented cock. Amy was now crouching above him, her bare legs bouncing dangerously above his head as she gently explored the effects of her twisted fantasies.

He suddenly rolled to one side, slid his hands underneath her body and used his strength to lift her up. Amy immediately draped her arms around his neck and kissed him, not letting go as he laid her down on the bed. Ben tried to untangle himself, only to realise that his wrist was still chained to Amy’s ankle.

“Leave it,” she moaned, as she rubbed lubricant between her open legs and watched as Ben’s ripped body pushed inside.

They made love and then lay handcuffed together on the bed as Amy explored the tiny creases on Ben’s forehead. She had seen him wince from the pain caused by her mesh, and maybe those were what she could now see. She loved how her actions were shaping his whole life and she kissed his forehead before burying back against his chest.

Ben cleared some stray strands of Amy’s hairs from his face, rattling his manacled hand as he did so, “Are you worried I might leave you?” he asked.

“Maybe we should do a twenty-four-hour handcuff challenge…” she whispered.

“With me chained to your ankle?”

“You’d be chained down here, darling” Amy purred as she straightened her leg.

Not wanting to leave a tell-tale handcuff mark, Ben followed her leg until his face was level with her waist. From there, Amy propped herself up on one arm and giggled as Ben tried and failed to return to the top of the bed. She gave a further flick of her leg to jolt Ben down to her crotch. There he stayed until Amy returned to make love.

*

Two hours later and they were both exhausted. Amy had locked Ben back inside his chastity cage and only then unlocked the handcuffs that held them together. They showered and dried and returned naked to their bed.

Amy looked at Ben with a quizzical smile, before sidling up to him and whispering into his ear. She pushed him backwards onto the bed and straddled his body, her long hair draped around them both.

“What do you want now?” Ben smiled, knowing her routine all too well.

Amy giggled nervously, jumped off and returned with a length of chain which she quickly padlocked around Ben’s neck.

“Shuffle down,” she breathed excitedly.

She took the end of Ben’s neck chain and locked it around her ankle and stretched out to hold Ben at the foot of the bed. Ben reached up, but still, most of her naked body was out of his reach.

“If only your legs weren’t quite as long,” Ben moaned

“Frustrating,” she smiled, “but at least you can kiss my feet.”

“You have lovely feet…”

“Good, and you get to sleep in a room that isn’t locked.

“I’m chained to your leg!” Ben moaned in aroused pleasure, his hand pointlessly shaking his cage. He stopped and looked up her naked body, spread out over the large bed.

Amy closed her eyes and focused on Ben’s warm breath on the soles of her feet. Then her toes slipped into his mouth and he bit down playfully as he sucked them. Maybe he would fall asleep with her toes in his mouth. That would be gorgeous. But minutes later and she was already asleep.

*

Two more years had passed, and Ben and Amy had taken chastity to a new level. Ben now wore a chastity device that Amy had designed herself and had had custom-made at great expense.

A heavy cock ring encircled Ben’s balls that was joined to a plate that ran behind his balls. On to this plate locked a solid steel top part that meshed with Ben’s Prince Albert piercing. The result was a solid block of silvery steel that completely enclosed and encased Ben’s genitals, with only a keyhole and a small hole through which to pee.

The inescapable block of steel tugged as Ben walked and he had taken to using a black leather belt to stop the device from pulling, or possibly tearing, his balls from his body.

Amy’s special design incorporated a maximum-security lock buried deep inside the device. The key had to turn 180 degrees and then push in further before it could engage the pins which, as Amy had explained several times, made it completely unpickable. Drilling was also not an option, as the drill would have to cut through steel and stop millimetres from Ben’s helpless cock.

Ben knew the dangers of wearing such a secure device and the very real risk that losing the key could mean losing his cock, or at least a lifetime in chastity. Either way, he would never make love to a woman again. But while he loved sex with Amy, the look of Amy’s teasing body in a short skirt and boots made even a lifetime of chastity seem like a wonderful idea.

Amy’s design also included an electrical shock device that only took orders from the small remote control in Amy’s pocket. The slightest push of her manicured finger against the button would incapacitate Ben, the trigger so sensitive that she would sometimes activate unintentionally. She knew from experience that bending down too far in her tight denim shorts could be bad for Ben’s health.

Once, when decorating their new house, Amy had brought him crashing down from a ladder by simply reaching down to pick up a paintbrush. They had both laughed at the sight of each other covered in white paint and Amy had kindly crouched down to wipe paint from Ben’s eyes. Another mistake as her denim shorts again tightened around her hips.

The shorts were still covered in paint, but it didn’t stop them from being one of Amy’s favourite pairs. She would glide around the house on a Sunday morning with the shorts tightly buckled around her hips, the remote control in her back pocket and a look of pure mischievous in her big brown eyes.

It gave Amy a wonderful feeling of control, able to bring Ben to his knees at her every whim. With Ben on his knees, she would stand over him, lift her skirt and let him explore her body and kiss the only key to his chastity device. For Amy, the fact that the key was hidden inside her expensive silk lingerie, resting against her vagina, was just a happy coincidence.

“One day the key will fall out of there,” Ben breathed, as he kissed her between her legs, “then its permanent for me.”

“I know,” she mouthed.

“I’ll be celibate.”

“And how do you feel about that?” Amy whispered; one thigh already wrapped around his neck.

“I could check every day to see if the key had returned.”

Amy cried out as she orgasmed.

Ben’s arousal was more than he could take while deadlocked inside the two-inch device,  “Oh fuck,” Ben whispered, well aware that it was only the tenth of the month.”

Amy’s birthday was the fifth of July and in honour of herself, she had chosen the fifth of every month as the day she unlocked Ben and the day they made love. The monthly release had brought a new magic to their relationship, and a new level of closeness as Amy helped Ben manage and focus his sexual desires.

Leading up to the day of release, Ben would focus more on more on Amy, transitioning from a partner, to a servant, to a lovesick slave. Sometimes though, not even kneeling on the floor and massaging her legs could divert his desire to make love.

“Do I have to chain you up?” Amy smiled with dancing eyes. Putting Ben in subspace, put her on a sexual high.

Ben grabbed his steel cock and smiled, “Not to the toilet!”

Amy giggled. Only days before, she had chained him to the toilet for the night. It had certainly kept him from being distracted by her body, as he had been unable to separate himself from the porcelain bowl, at least, that was until Amy came to pee in the night.

“Ok, somewhere away from your body… and those eyes,” Ben breathed huskily.

Amy unbuttoned his chinos, ran her nails up the inside of his thighs and grabbed the steel between his legs.

“Locked…” she whispered erotically.

He stared into her dark, all-controlling eyes. He may have been confined to a two-inch-long cock, yet his love for Amy was making him wonderfully lightheaded. His dropped his head to kiss her breasts that were tantalisingly on display under her low-cut white top, and then dropped back to his knees as his cock burned inside his block of solid steel.

“Fucking thing won’t open,” he panted, pulling at the steel, trapped in a mental orgasm where his body just couldn’t follow.

“I know… I have the key…”

“I can’t take this today… just chain me up somewhere far away,” he begged as Amy unhelpfully lifted her short tartan skirt and rubbed her thighs against his face.

She avoided his eyes as she padlocked the heavy chain to Ben’s chastity device, looped the chain over her shoulder and led him outside and over to the large oak tree at the bottom of their private garden.

Suddenly Ben cried out and fell to his knees.

“Opps, nipples too hard,” Amy smiled bashfully as she took the remote from her bra and then carefully replaced it even closer to her left nipple.

Ben followed cautiously as Amy’s boots swayed towards the end of the garden and then knelt down as Amy looped the chain around the tree and locked it back onto itself.

“I’ll leave you here while I…” Amy glanced away shyly.

“Masturbate?” Ben replied.

“Shush…”

“What about your nipples?”

“Umm, we’ll see won’t we…”

Amy blew him a kiss before she swung around and walked back towards the house, her hips rolling excessively. She sensed that Ben was trying to follow her and waited for the inevitable cry as the chain pulled tight.

“You’re chained, darling,” she called without looking back.

Ben pointlessly pulled at the chastity device as he watched Amy return to the house and back through the French windows. She stood in plain view as she pulled down her panties and sent Ben’s key tumbling onto the wooden floorboards. She was so pent up that the gentlest touch of her vibrator made her cry out. She dropped back onto the large white sofa with her legs apart and climaxed almost instantly.

Amy gazed out adoringly at her helpless chastised prisoner. It almost seemed unfair that she should have found someone like him. In his eyes, she would now be an untouchable Goddess, whose very presence would bring him untold joy.

Ben was trying pitifully to prize open his cock with a stick as she sauntered back with a self-conscious smile.

“That won’t work,” she smiled kindly, flipping her skirt over his head so he could run his mouth and nose around her panties and feel the outline of the key.

Ben breathed in deeply, sucking in her scent while madly shaking the solid steel that had swallowed his cock.

“Any feeling?” Amy asked.

Ben shook his head; he had never once managed to come in the device that Amy had designed. She bobbed down, stroked back his dark hair and pulled him closer to kiss.

“Probably best I leave you here while I’m in this skirt, “she whispered, “I’ll be back once I’ve put on some old jeans.”

*

An hour later and Amy, as promised, was dressed in jeans and jumper. She stood by the window cradling a cup of tea as she watched the rain fall. She had seen Ben try everything to get to shelter, but he had now given up and was huddled by the tree, soaked to the skin.

Amy pulled on some old boots and tramped outside under a large umbrella, “You ok?” she asked sympathetically.

“Jeans,” he observed.

“Yes,” she sighed, “you’ve seen enough and it's a long time to go until the fifth.”

“This rain is helping,” he croaked, “Focuses my mind on surviving.”

“You do look sexy in the rain,” she breathed, moving in closer.

They kissed for a few minutes as the sky drew even darker.

“I’d better unlock you,” she smiled kindly.

Ben traced his hands over her breasts, down over her hips, and up between her legs, “What do you have planned for the key today?”

She sighed, “Like you, the key’s in full lockdown.”

“Oh. Panties?”

“Very tight, I’m afraid…”

Ben traced the hem of her underwear through the warm denim, “Not going to fall out then?”

Amy’s long dark hair swished as she shook her head.

“Then leave me chained up.”

“What? You really want me to leave you here?” she cried incredulously, “In this weather?”

“Yeah, for a while.”

“It’s late… I’ll be in bed.”

Ben wiped his wet face against her jeans and looked up, “Why do I find the thought of you in bed and me chained up in the rain so sexy?”

“It’s not just you,” Amy smiled, “Do you know what’s going on in my jeans?”

“Oh fuck, tell me!”

“You can ask the key later,” she whispered between kisses.

*

Ben always worked hard in the days leading up the fifth of the month, as it took his mind off his coming release. He showered and washed his chastity device and tried to remember what his genitals looked like. He should take a photo because for thirty days a month they were simply not there.

Their relationship also changed during the month. The closer they were to the fifth of the month, the more Ben worshipped and obsessed on Amy. Instead of meals out with friends, he would cook her dinner at home. Instead of watching football, he would sit on the floor and massage her feet.

Their relationship was always stronger and more exciting as they approached the day of release. Amy loved to be loved and could never get enough of his attention and his adoring touch. She would masturbate more often, sometimes discreetly out of Ben’s sight, but sometimes using Ben’s lips as stimulation.

Helping Ben manage his overwhelming emotions gave Amy a wonderful power high. Sometimes he was unable to sleep next to her, her scent and her touch keeping him on an expectant sexual high. Amy would always oblige by opening the large wooden truck at the end of their bed.

“You’ll sleep well in here,” she whispered, “You can’t see or touch me.”

She would lower the lid and sit on it, listening intently to his breathing, “Is that nice?” she called.

“Let me try to sleep in bed,” he called, pushing up on the underside of the lid.

“Too late… I’ve already engaged the ‘bottom’ lock.”

“What?”

Amy rolled her eyes, “I’m sitting on you,” she called more loudly.

The box rattled again, but the lid remained closed.

Amy’s black nightdress perched on the lid for another hour until she was sure that Ben was asleep, and only then did she lock the box with the padlock. It was now 10 pm and only two hours away from the fifth.

*

Amy woke with a smile and flung the single sheet from her body. She jumped onto her hands and knees and prowled to the end of the bed. She tapped on the lid of the wooden trunk and the padlock started to rattle.

“I haven’t unpadlocked you yet!” Amy called, tingling with excitement. She had a flashback to waiting to open her Christmas presents, one of the happier memories from her childhood.

Still on all fours, she climbed onto the box and placed her lips against the lid, “Are you ready, darling?”

“Fuck yeah!” Ben cried repeatedly.

Amy was quivering uncontrollably and bit down on her lip and clenched her fists to try to regain control. She swung her legs down and sat on the lid, “Hey wait,” she giggled in response to desperate banging beneath her, “I just need to find the key to unlock the box.”

The key was in her hand, but still she sat there, legs apart and breathing deeply. She could feel his energy entering her through the lid, arousing her almost as if his cock was inside her.

“I just need to pee,” she called.

“Amy, please!”

She touched herself, already on the edge of a beautiful orgasm, “Be patient or I’ll flush the chastity key away… and you’ll stay locked up in that device forever.”

The box shuddered as Amy pushed her fingers inside herself, “I’ll fill up the box’s padlock with glue and leave you to starve to death …” She had barely finished her words before she orgasmed and howled out in pleasure, her bottom bouncing.

“Amy?” he called.

“Sorry, darling… now I really do need to pee.”

*

Amy returned and quickly unlocked the box. She pushed Ben back onto the bed and sat astride his chest as she inspected the lump of steel where once there had been male genitals.

“Let’s see if this key still works,” she giggled, “… think I almost melted it just now.”

She pushed it deep into the hole, turned it, and pushed it in further. Then she carefully turned it again to unlock the two halves.

*

They had made love incessantly, stopping only for lunch, and it was now almost six in the evening. Amy placed her bare bottom on Ben’s face and gently reassembled the chastity device and carefully turned the complicated key in the lock. His genitals had once more turned to steel.

“One day, if I don’t want to make love anymore, can I lock you up forever?” Amy’s breathed.

“Sure,” Ben whispered. “I’m not going to make love to anyone else.”

“Thank you…” her husky voice was barely audible, “It would be so sexy to just ‘lose’ the key.”

They were both panting, both on the edge of total arousal, but only one of them could go all the way. Ben’s lips were already working into her vagina soaking him with her scent. She came unusually quietly as they both reflected on Amy’s latest fantasy.

“I could just go for a run in loose panties,” Amy whispered, “Or a bike ride with no pants at all… that’s all it would take.”

“You might have to keep me away from your body after that.”

“I might have to lock you in the box every night,” she trembled, “I’ll lock you in with my favourite padlock.”

“You have a favourite?”

With the pressure in the chastity device intense, Ben rolled the hopelessly arousal woman off his face and onto the bed beside him, “I’ll cook dinner.”

She beamed in delight as she pulled on her running top.

“Run?” he asked nervously.

“Don’t worry. Tight panties,” she giggled, “… this time.”
