Pebble gets dommed

The scent of solder and ozone hung in the air of Pebble’s bedroom, a familiar perfume that meant progress. His desk was a chaotic landscape of wires, tiny screwdrivers, and the half-finished chassis of a custom-built Gundam model. Pebble himself was a study in focused energy, his tongue peeking from the corner of his lips as he twisted a minuscule bolt into place. His pastel-pink hair, a soft cloud he’d dyed last week, was tied back in a messy bun, but a few strands had escaped to frame his round, wire-rimmed glasses. He wore an oversized, faded hoodie featuring a chibi version of a character from a niche JRPG, and a pair of comfy shorts that did little to hide the soft, pale curve of his thighs.

A soft knock on his doorframe made him jump, nearly sending a tiny piece flying.

“Mia,” he squeaked, his face flushing a pretty shade of crimson. He fumbled to cover his project, as if she could possibly judge his nerdy passions after all these years.

Mia leaned against the doorframe, a knowing smile playing on her lips. She was the sun to his moon, all warm confidence and easy grace. Her dark hair was pulled into a sleek ponytail, and she wore a simple crop top and joggers that still managed to look effortlessly cool. “Don’t you ‘Mia’ me, dork. Whatcha hiding? Is it another one of your secret projects?”

“It’s not secret,” Pebble protested, his voice a little too high. He was always flustered around her, a constant, low-grade hum of anxiety and adoration. She was his only friend, his anchor in the choppy seas of high school. She’d defended him from bullies, shared her snacks, and never once made him feel weird for his love of cosplay, his addiction to doom-scrolling TikTok trends, or his androgynous style. “It’s just… delicate.”

“Uh-huh.” Mia sauntered into the room, her eyes scanning the organized chaos. She knew his space better than her own sometimes. She plopped down onto his bed, the springs groaning softly. “So, I was thinking we could marathon that new mech anime tonight. I brought snacks.” She held up a bag of his favorite sour gummy worms.

Pebble’s face lit up, his shyness momentarily forgotten. “Really? Mia, you’re the best!”

“I know,” she said with a wink. “Now, are you gonna show me or do I have to start digging?”

Laughing, Pebble turned back to his desk. “Okay, okay, just let me put this piece—” As he reached for a component, his elbow knocked over a small, discreet-looking black box that had been tucked behind his monitor. It fell to the floor with a soft clatter, the lid popping open.

Pebble froze. His blood ran cold.

Mia, ever curious, slid off the bed and knelt to pick it up before he could stop her. “Ooh, what’s this? Some kind of fancy tech kit?” She peered inside, and her smile slowly faded, replaced by a look of genuine, wide-eyed surprise.

Inside, nestled in black foam, were two items. One was a sleek, matte-black silicone plug, flared and curved, with a small, metallic ring at its base. The other was far more intricate: a small, polished metal cage, delicate yet undeniably functional, with a tiny, almost invisible wire leading to a small bullet-shaped vibrator. A matching lock and key lay beside it.

The silence in the room was thick enough to choke on. Pebble’s face was burning, a fire of pure, unadulterated humiliation. He wanted the floor to swallow him whole. He wanted to rewind the last thirty seconds and exist in a reality where Mia had never seen his shameful, secret little world.

“Pebble…” Mia’s voice was soft, devoid of mockery. She looked from the items in the box to his terrified face. Her expression wasn't one of disgust, but of intense, almost clinical curiosity. “What is all this?”

“I- I can explain,” he stammered, wringing his hands. His gaze was fixed on his worn-out rug. “It’s just… a thing. I bought it online. It’s stupid, I’m sorry, I—”

“Hey,” she said, her tone gentle but firm. She set the box down on his desk and stood up, closing the distance between them. She placed a hand on his shoulder, and he flinched at the contact. “Look at me, Pebble.”

Slowly, miserably, he lifted his head. Her eyes were soft, searching his. There was no judgment there, only a warmth that made his chest ache.

“Is this why you’ve been so… twitchy in class lately?” she asked, a new understanding dawning in her gaze.

He could only nod, his throat too tight to form words.

A slow, dangerous smile spread across Mia’s face. It wasn’t a mean smile. It was the smile she got when she was about to win a board game, a look of pure, unadulterated delight in a new and fascinating discovery. “So… this little plug,” she said, tapping the box, “and this… cage. Do they work together?”

Pebble’s blush deepened. He gave a tiny, almost imperceptible nod.

“Show me,” she commanded, her voice dropping to a low, sweet purr that sent a shiver down his spine. It wasn’t a request. It was a velvet-wrapped order, and a part of him, a part he kept deeply buried, thrilled at the sound of it.

“Mia, I can’t,” he whispered, his voice trembling.

“Yes, you can,” she cooed, her thumb stroking his shoulder. “You trust me, don’t you, sweet boy?”

He did. He trusted her with his life. That’s what made this so terrifying, and so intoxicating. He found himself nodding again, his body moving on autopilot.

“Good,” she said, her satisfaction palpable. “Now, I want you to put them on. Both of them. And while you’re at it…” Her eyes flicked to his dresser, where a pair of fluffy black cat ears on a headband and a simple black velvet choker were laid out from a photoshoot he’d done last week. “Put those on, too. I want to see the full picture.”

A whimper escaped his lips, but he was already moving. He grabbed the items and retreated to his small adjoining bathroom, his heart hammering against his ribs like a trapped bird. He could hear Mia humming softly to herself out in his room, a sound that was both comforting and utterly terrifying.

He fumbled with the cold metal of the chastity cage, his hands shaking so badly he could barely fit the ring behind his balls. He was already half-hard from the sheer humiliation of it all, which made the process even more difficult. Finally, with a soft click, he locked it in place. The feeling was immediate and overwhelming, a constant, constricting pressure that was a thrilling reminder of his submission. Next came the urethral plug. He’d only tried it a few times, the sensation alien and intense. He slicked it with lube and, with a hiss of breath, slowly slid the cool metal into his slit. It was a strange, invasive feeling, a deep, internal hum of potential.

Then the anal plug. He coated it generously, his face burning as he bent over, his back to the door. He pressed it against his tight hole, breathing deeply as he slowly worked the tapered silicone inside. It stretched him, filling him with a pleasant, full pressure. When the widest part slipped in and his muscles clenched around the slender neck, he let out a shaky sigh. He felt… complete. Owned.

He stood up, feeling the shift of the plugs with every tiny movement. He looked at himself in the mirror: a blushing, nerdy boy with pink hair, locked in a cage, filled in both holes. He felt ridiculous. He felt incredible.

He put on the cat ears, the fluffy black bands contrasting with his pastel hair. He fastened the velvet choker around his neck, the soft fabric a stark contrast to the cold metal hidden beneath his clothes. He took a deep breath and opened the door.

Mia was sitting on his bed, scrolling through her phone, but she looked up the moment he emerged. Her eyes roamed over him, from the tips of the cat ears down to his bare feet, and her smile returned, wider and more predatory than before.

“Well, well,” she breathed, her voice thick with approval. “Look at you. You look… perfect.”

Pebble squirmed, his hands flying to cover the front of his shorts. “Mia—”

“No, no,” she said, standing and walking towards him. She gently took his wrists and pulled his hands away. “Don’t hide. You’re beautiful like this.” She reached out and flicked one of the cat ears, making it wobble. “My pretty kitten.” Her hand then trailed down, ghosting over the choker before her palm flattened against his stomach, right over the place where the plug was nestled deep inside him. She pressed down, just slightly.

Pebble gasped, his knees buckling as the plug shifted inside him.

“Oh, did you like that?” she purred, her eyes sparkling. She leaned in close, her lips brushing against his ear. “I have a little app on my phone for these kinds of things, you know. For… smart toys.”

He could feel the vibration of her voice in his bones. He knew where this was going, and the thought made him dizzy with a mixture of dread and anticipation.

She pulled back her phone, her thumb tapping the screen. A moment later, a low, deep thrum started deep inside his ass. Pebble cried out, his hands clutching at her arms for support as the plug came to life, sending waves of pleasure radiating through his body. It was overwhelming.

“Shhh, shhh,” Mia soothed, holding him steady. She tapped the screen again, and a second, sharper vibration joined the first, this one emanating from the cage, from the very tip of the urethral plug buried inside him. It was a buzzing, electric jolt that made his whole body tense.

“M-Mia,” he choked out, his eyes wide. The dual sensations were maddening, a perfect, torturous symphony of stimulation that he couldn’t escape.

“There now,” she whispered, her voice a balm against the storm of sensation. “That’s my good boy. See? You can handle it.” She stroked his hair, her other hand still holding her phone, the controller of his body. “You know,” she mused, her tone casual, as if she were discussing the weather, “I think this look is really you. You should wear it tomorrow.”

Pebble’s head snapped up, his mind reeling from the pleasure and her words. “To… to class?”

“Mhmm,” she confirmed, her smile turning positively wicked. “The ears, the choker… and of course, your little friends.” She gave the phone a little wiggle, and the vibrations intensified for a second, making him whimper. “I’ll keep them on a nice, low setting. Just enough to remind you who you belong to. Just enough to make you squirm in your seat right next to me. How does that sound, my sweet Pebble?”

He was trapped. He was terrified. He was more turned on than he had ever been in his entire life. He looked into her warm, dominant eyes and knew, with absolute certainty, that he would do anything she asked.

He could only manage a small, breathless nod, his body trembling under the weight of her command and the relentless, buzzing pleasure.

***

The morning light was a cruel, bright thing. Pebble felt like a ghost moving through his own room, his limbs heavy with a potent mix of dread and exhilaration. The promise he’d made hung in the air, thick and suffocating. He was still locked in the chastity cage, the cold metal a constant, heavy reminder of his surrender. He hadn’t slept, the phantom hum of the vibrations still echoing in his bones.

With a shaky sigh, he reached for the bottle of lube on his nightstand. His hands trembled so badly he nearly dropped it. He bent over his bed, his face pressed into the cool fabric of his Gundam-themed duvet, and worked the slick plug back into his ass. The stretch was familiar now, but the context made it feel brand new, more invasive. Every time he shifted, he could feel its solid presence, a promise of the day to come.

He pulled on his softest, baggiest jeans, the denim doing little to hide the rigid line of the cage but at least offering a layer of psychological comfort. He chose a simple black long-sleeve shirt, the dark color a meager attempt at hiding the flush he knew would be permanently on his face all day.

A soft knock. It was Mia. She entered without waiting, looking far too cheerful for the ungodly hour. She held up a small, gleaming brass key, the one to his lock, and gave it a little wiggle.

“Ready for school, pretty Pebble?” she asked, her voice syrupy sweet.

He just nodded, his throat too dry to speak.

She walked over to him, her movements fluid and confident. She reached into his pocket and, with a practiced touch, tucked the key into the small change pocket of his jeans. Her fingers brushed against the hard plastic of the cage, and he jolted.

“Oops,” she giggled, not sounding sorry at all. “Almost forgot. I’ll be holding onto this for you today. Don’t want you getting any silly ideas about taking your new toys off.” She pulled the key back out, leaving his pocket empty and his fate sealed. She dangled it in front of his face before slipping it into her own purse. “There. Safe and sound.”

He watched her, his heart a frantic drum against his ribs. This was real. It was really happening.

“Now,” she said, her eyes twinkling. “The finishing touches.”

He turned to his mirror, his reflection a pale, nervous wreck. His hands fumbled with the velvet choker, the soft fabric feeling like a brand against his skin. He fastened it, the simple act feeling like a final, irrevocable seal on his submission. Then, the cat ears. He positioned the headband, the fluffy black ears a stark, ridiculous contrast to his pink hair and terrified expression. He looked like a prey animal trying to mimic a predator, a pathetic, trembling kitten.

Mia came up behind him, resting her chin on his shoulder. Their reflections stared back at them: the confident, smiling girl and her blushing, adorned pet. “Perfect,” she whispered, her breath warm against his ear. “Let’s go. Don’t want to be late.”

The walk to school was a blur of anxiety. Every step made the plug shift inside him, a subtle, maddening reminder of its presence. He kept his head down, his pink hair a beacon he wished he could hide. He could feel the stares, the whispers, real or imagined. He was a freak, a boy in cat ears and a choker, and nobody even knew the half of it.

They sat in their usual seats in the back of Mr. Harrison’s math class. The drone of the teacher lecturing about quadratic equations was a distant, irrelevant buzz compared to the one Pebble was anticipating. He kept his hands clenched in his lap, his knuckles white, his gaze fixed on the meaningless scrawl on the whiteboard.

Mia sat beside him, calm and collected, her phone resting face-up on her desk, hidden by a textbook. She didn’t look at him. She just tapped her screen once.

A low, deep thrum bloomed inside Pebble’s ass. He jumped, his knee banging loudly against the underside of his desk. A few students glanced back, and he shrunk down in his seat, his face burning. The vibration was a constant, teasing pressure, a low hum that seemed to resonate directly into his prostate. It wasn’t enough to make him cum, but it was more than enough to make it impossible to think about anything else.

He tried to focus. X equals negative b plus or minus the square root of… The plug pulsed, a slow, rhythmic wave that made his toes curl in his sneakers. He could feel himself leaking inside the cage, a traitorous response to the stimulation. He squeezed his thighs together, a desperate, futile attempt to quell the building pressure.

Mia tapped her screen again. The vibration in his ass intensified, and a new, sharper buzz joined it from the front. The urethral plug came to life, a focused, electric tingle that shot straight up his shaft. It was a shocking, exquisite sensation that stole the air from his lungs. He let out a choked, silent gasp, his hand flying to his mouth.

His entire body was trembling now. A fine sheen of sweat broke out on his forehead. The dual stimulation was a perfect, torturous storm. The deep, filling hum in his ass and the sharp, insistent buzz in his cock were warring for his attention, and he was losing. His vision swam, the numbers and letters on the whiteboard blurring into nonsense.

He risked a glance at Mia. She was looking at him, a look of intense, predatory concentration on her face. She watched him squirm, watched him fight a losing battle against his own body. She slowly, deliberately, slid her thumb up the volume bar on her screen.

The vibrations kicked up another notch.

It was too much. The pressure that had been building in his core finally snapped. His back arched involuntarily, a silent, convulsive shudder wracking his frame. His eyes rolled back as his orgasm tore through him, not in a rush of pleasure, but in a series of tight, agonizing spasms. He could feel his cock twitching uselessly in its cage, spurting thick, hot ropes of cum that had nowhere to go. It backed up, leaking messily from the slit and soaking into his underwear, a warm, sticky shame. He bit down hard on his knuckle to keep from crying out, the pain a sharp anchor in the sea of overwhelming sensation.

He slumped in his chair, panting silently, his body limp and spent. The aftershocks made him jerk, his muscles twitching with residual pleasure.

He looked at Mia, his eyes pleading. It was over. He’d done it. He’d cum in the middle of math class.

Mia just smiled that sweet, wicked smile and tapped her screen one last time.

The deep, filling vibration in his ass stopped.

But the sharp, insistent buzz inside his locked, sensitive cock did not.

It continued its relentless, maddening work, a constant, buzzing torment on his hyper-sensitive, post-orgasmic flesh. He was trapped, spent, and utterly at her mercy, forced to endure the overstimulation for the rest of the class.

***

The bell signaling the end of math was both a salvation and a death sentence. The buzzing in his cock didn't stop. It was a constant, high-frequency hum that kept him on a razor's edge of overstimulation. Every step to his next class was agony, the friction of his jeans against the cage amplifying the relentless vibration. He could feel the sticky mess cooling in his underwear, a shameful reminder of his loss of control in front of Mia.

Chemistry was worse. The classroom was colder, and the shivering that had taken hold of his body was now impossible to hide. He sat hunched over his notebook, trying to copy notes, but his hand was shaking too badly. The lines of chemical formulas were a scrawled, useless mess. A new pressure was building, a deep, insistent ache in his bladder. The two large glasses of water he’d chugged that morning in a nervous haze were making their presence known. He clenched his muscles, trying to hold it, but the effort only made him more aware of the plug filling his ass, a solid, unyielding presence against his protesting bladder.

Mr. Davison, the chemistry teacher, was pacing at the front of the room. “Alright, who can balance this equation for me? It’s a tricky one, but I know someone here can do it.” His eyes scanned the room, a predator looking for the weakest member of the herd. They landed on Pebble.

“Pebble. Why don’t you come up and show us how it’s done?”

Pebble’s blood turned to ice. A collective, sympathetic groan went through the class. Everyone knew what happened when Pebble got called to the board. He froze. He stammered. He failed.

He looked at Mia, a desperate, pleading glance. She just gave him a small, encouraging smile and, under the cover of her desk, gave her phone a little tap.

The buzzing in his cock kicked up, becoming a sharp, insistent thrum. It was a clear message. *Go.*

His legs felt like lead as he pushed himself up from his chair. The entire class was watching. He could feel their eyes on him, on the ridiculous cat ears, on the velvet choker, on the way his whole body was trembling. He walked to the board, each step a jarring movement that sent shocks through his overstimulated system. The pressure in his bladder was immense now, a hot, heavy weight that threatened to spill with every step.

He took the marker from Mr. Davison’s outstretched hand. His fingers were so numb with vibration and fear he could barely grip it. He stared at the equation on the board. The numbers and symbols swam before his eyes, meaningless shapes. His mind was a screaming chaos of sensations: the hum in his dick, the ache in his bladder, the fullness in his ass, the weight of every stare.

He could feel Mia’s eyes on him, burning into his back. He knew she was enjoying this. He was her little project, her trembling toy.

He had to do it. He had to hold on.

He took a shaky breath and raised the marker to the board. His hand was a blur of tremors. He tried to write the first coefficient, but it came out as a jagged, pathetic scribble. A few snickers rippled through the room. His face burned hotter than a Bunsen burner.

*Focus. Just focus.*

He tried again, forcing his hand to be still. He managed to write a number, but his mind was blank. What came next? He couldn’t remember. He couldn’t think. All he could think about was the buzzing, the pressure, the humiliation. He felt so small, so incredibly tiny, standing there in front of everyone, a complete and utter fraud.

His body started to shiver in earnest, deep, wracking shudders that he couldn’t control. It was like he was freezing, but he was burning up. His teeth started to chatter. He clenched his jaw, trying to stop it, but it was no use. He was a vibrating, trembling mess on display.

He squeezed his eyes shut, a single, hot tear escaping and tracing a path down his flushed cheek. He pictured Mia’s smile, her praise. *Good boy.* That’s all he wanted. To be her good boy.

He opened his eyes. Through the haze of panic and sensation, the equation suddenly clicked. It was just numbers. Just rules. He could do this.

His hand, still shaking, flew across the board. He scribbled coefficients, balanced molecules, added electrons. It wasn't neat. It was frantic and desperate, but it was right. He finished with a final, trembling slash and slammed the marker back into the tray.

He turned to face the class, his chest heaving, his body still quivering like a leaf. He couldn’t meet anyone’s eyes. He just stared at the floor, his entire being focused on not pissing himself, not screaming, not falling apart.

Mr. Davison walked up to the board and scanned Pebble’s frantic work. A slow smile spread across his face. “Well, I’ll be damned,” he said, clapping Pebble on the shoulder. The contact made him flinch. “Perfectly balanced. Even with all that… creative energy. Well done, son. You can take your seat.”

A wave of something washed over Pebble. It wasn’t pride. It was a hollow, dizzying relief. He stumbled back to his desk, his legs barely supporting him. He collapsed into his chair, the jolt sending a fresh wave of sensation through him.

He risked a look at Mia. Her phone was face down on the desk. She wasn’t looking at the board, or the teacher. She was looking at him, her expression soft, her eyes filled with a warmth that made his chest ache. She reached over under the desk and gently squeezed his trembling knee.

The buzzing in his cock finally, blissfully, stopped.

The silence in his head was deafening. He was empty. He was spent. He was hers. He sat there, shivering and small, a survivor of a storm only he could feel, and waited for the bell to finally, finally, set him free.
