"Come, darling," Belinda cried as she took James's hand.
From the excitement in her over expressive brown eyes, and the way she extenuated her rolling hips, he knew that their new toy had arrived.
Standing in the middle of the open plan lounge was a cube-shaped metal box about a foot and a half across. There was a hole on one side, like you would find on a smother box, and the top was covered with a glass-like sensor. The steel box was heavy, but Belinda had secured it further by chaining it to the couch.
Belinda's short cream dress winkled as she crouched down and pressed a green illuminated button. The top half of the box lifted on its hydraulic hinges, the two halves of the hole separating to reveal a thick padded black leather interior.
"Does it work?" James asked.
"Aha," Belinda breathed excitedly, "It obeys whoever sits on it."
"And the movie?"
"Oh, you'll like it."
James unbuttoned his shirt; he always ended up naked in these games and so he might as well start the process. He wrapped one arm around Belinda's waist and kissed her, holding her tightly as he ran his hand up inside her dress and across her butt.
"You're naked too," he observed, his cock already hard.
"Can you imagine a sexier key?"
"No, but can I trust it?
"Guess you'll find out..."
James wanted to make out then and there, but Belinda's heels were stepping impatiently as she tried to disperse her excitement. "In the box!" she insisted, holding his wrist, and watching over him like a sentry as he lay down on his back and placed his head inside the lower half of the box, his neck fitting snuggly into the lower part of the hole.
Belinda stood over him, performing a little dance to remind him that she was naked beneath her dress. She then leaned over and pressed down on the lid, her dress riding up as the box closed with an ominous thud.
James's head was now consumed within the solid steel box. Its welded joints were secure and unbreakable, with no evident way to unlock it. The black leather interior took away all sight and sound, leaving James in total sensory isolation. With no other possible way to communicate, Belinda clicked open the videocall App on her phone.
"Hi in there," Belinda breathed, her lips inches from her phone, "Shall we give my body the ultimate power it deserves?"
James stared at the image of Belinda's face that now filled the wide virtual reality style screen inside the box. His cock was already straining as he subconsciously tried to kiss her larger-than-life lips.
"The sensors can scan anything," Belinda whispered, "My handprint, my breasts... or I can simply sit on it."
She giggled, turned, lifted her dress, and sat her bare bottom down on the lid of the box. The sensors came to life, flashing as they analysed the shape and weight of her curves that pressed and spread on the lid. She shifted to give it another flash of her naked body, making sure that every tiny detail of her bottom was logged. Once her unique shape had been secured in its memory, the light turned red, and multiple deadlocks slammed closed inside the box.
"That's it darling, the box will now stay locked until it senses my exact shape again," Belinda whispered seductively, "I'm the only girl in the world who can free you."
Belinda was buzzing with the knowledge that the weight and shape of her bottom was as unique as her fingerprint. She stood up, smoothed down the soft fabric of her dress and crouched down to explore their new toy. There was a vent that let in air through the lid, and a hole for a straw that could be used to keep her prisoner alive. Otherwise, it was ominously solid.
"No keyhole," Belinda whispered into her phone.
"Fuck, this is secure," James's deep aroused voice replied, his hands tracing the steel exterior, "How do I even start to get out?"
"You find a girl with a butt as cute as mine," Belinda suggested.
"There is no one."
"Correct answer, darling," she giggled, already unbuckling his jeans, "Either I sit on you... or you spend your life locked in my virtual reality," Belinda purred, as always mouthing her threats in her uniquely slow and sensual way.
Belinda touched her phone again and a pre-recorded video of her masturbating appeared on James's large screen. Her legs were spread, and her shaved vagina glistened as the vibrator touched her body.
"One you prepared earlier?" James breathed.
Belinda had gone shy, "I don't know what you mean?"
Belinda lifted her dress and sat on the box with one hand beneath her left cheek to ensure she didn't inadvertently provide the code to unlock him. The movie was playing inside the box and now her real-life damp vagina was hovering temptingly close to the air vent. She could feel the air being sucked inside, her scent filling the tiny space, ensuring that James's sight, hearing, and smell would soon be overwhelmed by her body.
"Fuck, I need you now!" James cried.
"I know you do," Belinda mouthed, enjoying his increasingly frantic touch.
She stood up and straddled his body, slowly sinking down on to his erect cock. James thrusted blindly against her, his body bucking and lifting Belinda for the few minutes it took for them to climax.
"Fuck, amazing!" he cried, his words lost in the soft leather that encased his head was also being drowned out by the soundtrack of Belinda's never ending canned masturbation.
Belinda rose slowly to her knees, James's erect cock pulling free as she moved. His hands ran up the back of her thighs, squeezing and pressing against her flushed flesh. He ran a finger between Belinda's cheeks, making her cry out in surprise, her body trembling as he eased her back on to his waiting cock.
Slowly, they went again, Belinda's breathy voice morphing into moans and then cries as James's cock pushed inside her. She orgasmed and flopped down on to her headless man with the pre-recorded movie of her slow and noisy orgasm still playing on James's screen.
"How long's the show?" James gasped.
"...Endless loop," she mouthed.

Sophie, Belinda's dreamy-eyed twenty-three-year-old daughter sauntered into the lounge, flaunting herself as usual in just underwear and a tight white top. Her hazelnut eyes widened as she saw the box, "It arrived?" she smiled with interest.
"Try it," Belinda offered.
Still sleepy, Sophie flopped down on to the lid, her feet spread, and her knees pinned together. Frustration crept in as the light stayed red, and she bounced on the sensors as if punishing them for their disobedience. Not wanting to admit defeat, she sighed and wandered off to play with the coffee machine instead.
Belinda touched her phone and was rewarded with a close of James's wonderfully aroused eyes, "Oh Jamie, you're so fucked!" she whispered, "It really works. Sophie can't open it. You'll have to be so nice to my body if you want your freedom."
Belinda's high heels clipped proudly as she strutted over to the kitchen. She may have been in her forties but playing with James made her feel sexier than ever and she smiled cheekily as saw that her dress had ridden up to give a glimpse of her butt.
"James is really off-limits today," she bragged to her daughter.
"That's cool," Sophie shrugged nonchalantly with a jealous glance at her mother's flirty dress.
"No really. Until it scans me again there is no way to let James out."
"Nice," Sophie murmured, her unbrushed chestnut hair hanging untidily across her face.
"Here, let me help you," Belinda tutted, taking the empty coffee cup from her daughter's dreamy hand.
Sophie's interest had returned, and she padded back to the box determined to prove her mother wrong. Her mother had been naked and so she pulled down her bright pink panties and sat naked on the box with her legs stretched out in front of her. "Come on!" she mouthed as the light stayed red. "Maybe after a big breakfast?" she goaded as Belinda returned with her coffee.
Belinda didn't take the bait and simply waited as Sophie sat on the box sipping at her coffee. Every few minutes the scanner lit up, sensing Sophie's body, but every time the box stayed locked. James called out a few times, but with Belinda's phone switched off and her orgasms still dominating his world, his words never escaped the soundproof interior.
"The box only answers to me," Belinda smiled. It gave her a thrill, as did James's hands that reached for her legs as she sashayed past.
Sophie finally stood up and meandered back to the kitchen bench, "Guess I'll have to wait 'til I've got the body of a forty-year-old woman," she teased.
Belinda smiled sarcastically as she touched her phone, "Ready, Jamie?" she whispered.
She circled the box before easing up her dress and sitting down on the lid. Hundreds of measurements were scanned and checked, each one matching perfectly as the light turned green, and the deadlocks released. Belinda stood up, modestly turned her back and wiggled her tight cream dress back into place over her hips.
Suddenly, Sophie sprang to life, quickly darting back to the box and sliding her brattish pink panties into place on to the sensor.
"Sophie!" Belinda cried.
But Sophie planted herself firmly, her hands gripping the sides of the metal box, as the sensors learned every curve of her body. Belinda stood frozen as the light turned back to red.
Sophie jumped up, skipped across the room, and sunk down on to the large couch, "It only answers to me now!" Sophie laughed, propping her feet on the cushions to show off her incarcerating curves.
Belinda's look of surprise morphed into a smile, "Nicely done, sweetie," she admitted.
Sophie looked happy, giggling uncontrollably as she swung her knees from side to side. Belinda calmly hitched up her dress and sat back on the lid and was not surprised when the light stayed red.
"Tell me again how fucked James is," Sophie giggled as she tickled her own thighs, "You better me so nice to the key!"
Belinda looked down as the light flashed red again, "Sorry Jamie," Belinda whispered into her phone, her aroused and twisted mind going into overdrive as her moist lips brushed the screen, "Someone's changed the locks."
James's first concern was loud and graphic and only inches away, "Please pause the movie, Bel?" he panted, Belinda now having orgasmed dozens of times.
"Opps, is that still on?" Belinda touched her phone to cut the feed.
"Feeling a little helpless in there?" Sophie called from across the room.
"Bel, get her to open it," James's deep breathing echoed through the phone.
"How," she whispered, "do you know how hard it would be to get a grown woman to sit still on the box against her will? If she moves during the scan or tenses her body even slightly then her shape would change."
"And Mum doesn't have a twenty-three year old body anymore," Sophie teased.
"No, she doesn't, but..." James's response was cut dead by an impatient tap of Belinda's phone.
Belinda looked over at her daughter, "Well, feel free to keep him locked up while I take a bath," she sighed, dropping her phone into Sophie's lap.

Sophie hugged her legs into her chest and grinned. She loved being part of their games, especially when her mother trusted her with James. James was now hers until her mother returned. She picked up the phone, rolled over and took a picture. Seconds later a close of her bottom, with pink panties bunching and riding up, filled James's screen.
"Thought I'd give you a chance, Jamie," she whispered into the phone, "Show you the key."
Sophie paced over to the box as James's gorgeous strong hands stretched up and pressed down on the sensors. It was such a pathetic attempt to recreate her butt that Sophie almost felt sorry for him.
"It didn't even recognise that as a butt," Sophie giggled.
James tried to guard himself as Sophie dropped down to straddle his waist, but this time she simply lay down on his body and nuzzled her head into his bare chest.
