Planet Telex

D29 shifted uncomfortably in place, trying not to wilt under his Mistress's gaze. He resisted the urge to try and adjust the metal contraption hanging off his hips, knowing doing it so soon would be frowned upon.
"Hopefully this should keep you more… contained, Assistant." Eyes of Aquamarine said, idly spinning the keyring around her finger. "Don't try to mess with it. I'll know if you do."
D29 groaned and wriggled his hips in frustration against the chastity belt. "Yes… yes Mistress. I didn't see why you had to…" D29 trailed off with a blush, averting his eyes. "Please, not for too long, Mistress…"
"It's staying on until I say so." Aquamarine replied, pocketing the keys, the three identical copies kept on the same ring. "And, the edging was to make it more… entertaining for me. I could sit in that for a month without problems, you know…"
The Assistant mumbled something under his breath in response, causing Aquamarine to raise an eyeridge.
"What was that?"
"T-that you wouldn't have to deal with teasing during it, Miss!"
Aquamarine smiled. "That's expecting a lot… that I'd bother teasing such a disobedient Assistant… I won't need to, anyway." She paused to allow D29 to try and reply, but cut him off before he could say a word. "Now, back to your tasks. I have dinner with a coworker, and I expect everything to be done when I return home, without distractions. Unlike yesterday."
D29 hung his head a little. "Yes, Mistress Aquamarine. Everything will be done when you return."

D29 was thankful he did not have to leave the apartment this evening. His clothing and most of his Mistress's were done at home, but every week he would have to take Aquamarine's workwear to the dry cleaners, which necessitated a walk down the road, and his current flustered state would be quite obvious to those he passed.
While folding one of his freshly washed dresses, he looked down at the one he was wearing. The chastity belt hugged his hips underneath, the band pressing closely against his body feathers with only a slight bump in the fabric hinting to its existence. Maybe if he cleverly positioned some feathers, it'd be less obvious… not that anyone would really pay attention to him, being an Assistant.
With a sigh, he placed the dress down on the stack of the others, each looking almost machine folded, and moved on to the next. If only he'd been a little bit quicker, Mistress would never have known he got off… but he was behind on chores, and she was home early… He blushed at the memory of Mistress walking in to him hurriedly attempting to clean himself up, too caught up in the moment to hear her open the front door. Not that it would have mattered, trying to pull his dress down would have only got it messy, and it's hardly like he could have hidden his shaft in the form fitting dress…

He had to wonder where Mistress got it from, on such short notice. The belt was clearly fit for him, as it was relatively comfortable and didn't budge at all. Did she have it already, and was just waiting for an excuse? Either that, or her Ministry role meant she could just procure these things in a hurry… Regardless, it was now locked, the curved metal plate held against his slit unmoving and unignoreable.
D29 looked down, blushing. He was rather worked up from before, Mistress holding him down on the bed and forcing him to edge himself before the belt went on. He cautiously put a hand against it through his dress and rubbed uselessly against the plate with a whimper. For some reason, ever since Mistress pulled the belt out to put on him, the thought of it was… stubbornly arousing. Chastity wasn't something he'd ever thought of before, and now he was in it, he was more worked up than he was able to remember. Was this part of Mistress's punishment? Did she know it'd elicit this reaction, and make it unbearable? Was that what she meant when saying she wouldn't need to tease him?
The Assistant pulled his hand back from the belt and gave a frustrated whine under his breath. Barely an hour in it, and he wanted to cum more than he had when he was caught…

Aquamarine tried to keep her grin concealed as she unlocked the door and pushed it open. She was interested to see what her Assistant would get up to after chores, and so kept quiet as to not give them time to hide it.
"Mmmph…"
Eyes of Aquamarine leant on the doorframe of her bedroom, seeing D29 laying on the bed with his dress pulled up, helplessly rubbing at the belt plate and whimpering loudly, and decided to watch for a minute. "Having fun there?" She said, with a small smile.
D29 jumped up once he realised Mistress was there, trying to fumble his dress back over his crotch. "N-ngh! H-hi Mistress! I'm… I'm just…"
Aquamarine's smile spread as her eyes locked onto her Assistant's, who was trying to smooth over his crumpled dress. "Are your tasks done?"
"Yes… yes Mistress…" D29 whimpered, a deep blush covering his face. "Everything is done…"
"Good." Aquamarine said, stepping forward with her hand in her jacket pocket. "I have a present for you."
D29's head perked up a little bit. "Please tell me they're the keys…"
"Mmhmm, they sure are." Aquamarine said, pulling D29's wrist in. "Close your eyes, open your hand up."
D29 was confused why he'd need to do that, but obeyed anyway, closing his eyes tight, not even peeking, as Mistress placed something in his hand. It felt… hard, like it was some sort of rock, but it seemed to be shaped like a cube…
"Open your eyes."
Aquamarine couldn't contain her grin when the look of dismay came over D29's face. It was indeed his belt keys, suspended in a solid glass cube.
"M-Mistress!"
"Shh, shh. You can unlock your belt whenever you'd like." Aquamarine pulled her hand away, leaving her Assistant in possession of the only way out of his chastity. "But I'll know."
