Kate woke the next morning more aroused that usual. She pulled off the single white sheet, her bare feet stepping quickly across the cold bathroom tiles. She peed and then bounced back to her bedroom with a faint imprint of the toilet seat still showing on her bare butt. She jumped back under the sheet and grinned as she thought back to Kai and the night before.
Why would any man lock his cock in a chastity cage and hand over control to some unknown woman? And more importantly, why was the thought of this making her hot? She cried out in frustration; it was maddening to be alone when she was this ready to fuck. If only Kai was here... ah, no that wouldn't help. She lay back giggling as she imagined thrusting her hips against Kai and his one-inch metal cock.
She reached for her phone but quickly tired of Instagram, turning her attention instead to the keyholding app. 'Let's have some fun' she grinned breathily as her hips pulsed beneath the sheets.

Kai was in a meeting at work when his cock cage started to vibrate. After months of being starved of attention, his captive cock awoke, tingling and swelling from the desperately needed sensation. However, with the steel locked tightly around his cock and balls, the pleasant vibrations soon turned into a cruel tease. His cock swelled as it crushed into the bars at the end of its cell, forcing his balls to stretch from his body. The tingling became an ache as pre-cum oozed from his swollen red tip that bulged between the thick close-centred bars.
Suddenly he cried out in pain as a surge of electricity stung his cock. "Kai?" his colleague asked with concern, slipping out of her chair, and gliding around the desk to where Kai was now bent double with his head between his knees.
"It's okay, Ellie," he panted, glancing surreptitiously up at her short tan skirt and long pantihose covered legs. There had been sexual chemistry between them for months, but Kai had been helpless to make a move with his cock was under another woman's lock and key.
"Can I get you some water?" Ellie asked as she edged closer.
Another crack of electricity fired into Kai's cock. Desperate not to cry out, he tensed his body, only for his face to knock against Ellie's thigh. Ellie took another step closer, her body alight as she comforted his head against her pantihose cover leg.
"Anything I can do?" she smiled, running her fingers through his hair.

Kate was still in bed, running her fingers over her bare breasts and imagining they were her lover's lips. She reached her hands up to the top of the bed and imagined that she was being pinned down. She sighed, it wasn't the same on her own and she rolled over to check her phone.
The app showed the location of Kai's chastity cage which allowed her to track him at all times. She smiled as she chose a new avatar for her twisted friend, a cute face with big pleading eyes surrounded by a locked padlock emoji.
She flicked back to the main menu. Her fingers danced over the vibrate and shock controls to the beat of the song that was stuck in her head. She then found a function that vibrated her phone and slipped it between her legs where it stayed until the battery died.

With Kai still in sporadic unexplained pain, Ellie offered to drive him to her apartment that was only five minutes from the office. Once inside, she insisted on wrapping her arm around him as she led him to her couch. With Ellie fetching some pain killers, Kai grabbed his phone and dialled his keyholder.
Kate took her time to answer, enjoying the vibrations between her flush thighs. She reluctantly opened her legs and clicked 'answer' with her phone still pressed tightly against her shaved crotch.
"Kate?" Kai hissed, "What are you doing to my cage?"
Even dampened between her legs, his voice sounded wonderfully desperate. She closed her big brown and grinned as she pictured his terror.
"Oh, it works then?" she mouthed.
"You aroused me like hell and then almost blew my cock off with the shock!"
"Opps."
"We need to meet now."
"I'm in bed..." Kate purred, delighted by how his gravelly tones were vibrating against her clit.
"Well, I'll come to you."
"No, you won't," she mouthed, "I've geo-locked you ... move more than ten meters and bang!"
Fuck. Kai was about to explain that he was at a friend's home but stopped. Chastity was supposed to be a way to worship and serve his keyholder. He shouldn't be at another girl's apartment, ready to fuck if only he could escape the cage.
Kate cut the call and lay back to enjoy a fit of aroused giggling. She felt wonderfully alive and again reached for her vibrator. Maybe she liked Kai more than she realised or maybe she just enjoyed her power. She quickly orgasmed and slinked away to the bath where she lay hidden by bubbles as she pictured Kai's predicament.

Kate washed and blow dried her hair and dressed as respectfully as she could in a black blouse, white jeans, and brown ankle high boots in an attempt to impress her older, professional friend. She caught a bus to his location, took a deep breath and tapped on the door.
"Oh," Kate gasped as a tall, elegant women in a tan skirt suit answered the door, "Is Kai here?"
"Yes..." the woman replied.
Kate fidgeted nervously as she followed Ellie inside to where Kai was sitting on the couch with a hot water bottle on his lap. Kate was confused, how could Kai be in a relationship when he didn't even have access to his cock.
"Okay, I didn't know," Kate blurted, "I'm sorry about the electric shocks."
"What shocks?" Ellie asked, her arms crossed defensively.
Ellie frowned disapprovingly as she checked out the younger woman's tight white jeans that were straining to contain both her body and her phone that was pinned against her round butt, its outline clearly showing through the soft fabric.
Kate stared back indignantly, pushing waves of dark silky hair from her face, "Well I assumed you were single 'cos you let me lock up your cock," she snapped, turning to leave.
"It's supposed to be our secret, Kate!" Kai growled.
"You know her?" Ellie exclaimed.
"I'm leaving," Kate hissed.
"No, please don't," Kai replied.
"Show her then!" Kate snapped.
Kai slowly stood, unbelted and pulled down his suit trousers and briefs to reveal the locked black steel device that enclosed his penis, "I asked Kate to lock in me chastity. She can shock me and lock me to a location. Right now, I can't leave your flat." His cock twitched and crushed as Ellie stepped closer and knelt to feel his engorged balls. Her touch felt wonderful only adding to the ache.
"Unlock him now!" Ellie snapped.
"No, it's okay," Kai replied.
