Locked：01
My name is A Cheng, a junior. The dorm is a four-person room, but now only A Lin and I live here—the other two moved out early to live with their girlfriends.
Everything spiraled out of control starting that Wednesday night.
Around ten that night, I came back from the study room carrying a bottle of ice-cold mineral water. When I pushed open the door, A Lin had just finished showering and was changing with his back to me. His hair was dripping, his upper body bare, and his lower body wrapped only in a white towel loosely tied at the waist.
The moment the light came on, I saw that spot under the towel… something was off.
It wasn’t a bulging morning erection—there was a clear metallic outline.
A silver-black chastity cage, streamlined design, dense bars at the front, thick locking ring at the base, with a small silver padlock hanging from it. The cage was slightly deformed from being stretched, the flesh inside swollen deep red, clear fluid squeezing out from the gaps and dripping down the metal onto his inner thighs.
My mind froze. I stared for five or six seconds.
He noticed, turned around, and the towel nearly slipped. He grabbed it, a flash of panic crossing his face, but quickly put on his usual cocky grin.
“What are you looking at? Never seen a guy shower before?”
I swallowed, my voice dry: “……What’s that?”
He glanced down and shrugged: “Chastity lock. Bought it myself. Been wearing it for almost three months.”
He took two steps closer, the towel edge slipping a bit to reveal more details—titanium alloy, reflecting cold light, the lock engraved with a serial number, custom-made. The small hole at the front was just enough for urine, but right now it was dripping precum, glistening.
“Why lock it?”
“Feels good.” He tapped the front of the cage with a crisp “ding.” “Started as nofap, then realized being locked is even more intense. Can’t help getting hard until it hurts, but can’t get off. That feeling… tsk, you know what I mean.”
He narrowed his eyes at me: “Don’t tell me you’ve never tried it?”
I shook my head, face burning.
He simply yanked off the towel, leaving only the cage hanging between his legs. The skin at the base was red from long-term wear, his balls squeezed out and bulging like ripe fruit.
“Want to touch it?” His voice was low, teasing. “The key’s in my drawer. If you’re curious, I’ll show you how to unlock it.”
I stared at it, heartbeat pounding in my ears. The metal reflected the light, and the flesh inside was still twitching slightly, as if greeting me.
In that moment, only one thought: Damn, that thing looks so good on him.
Seeing I didn’t move, he hooked the front bars and pulled down, making the glans push out more visibly.
“Been locked forty hours, haven’t unlocked once. Now it’s so hard it feels like exploding, can only leak. Want to know…… what the leaking stuff tastes like?”
I didn’t answer. My legs were already weak.
He smiled, wrapped the towel back, turned to rummage in the drawer and jingle the keys: “Alright, stop pretending. Starting tomorrow, if you still want to watch, I’ll let you lock it on me yourself. Or…… you want to try it too?”
That night I couldn’t sleep until 3 a.m., my mind full of the silver-black cage between his legs and the leaking flesh inside.
The next night, the dorm lights were dimmed to the lowest, only the bedside lamp left, casting long shadows in the warm yellow glow.
When I came back from showering, A Lin was sitting on the bed with a piece of black velvet cloth spread on his knees. On it lay two keys side by side—a silver one hanging from the chain around his neck, and a matte black one. Beside them was a brand-new pink resin chastity cage, one size smaller than his, with denser front bars and a transparent pink base. It looked…… especially suited for humiliation play.
He looked up, lips curling: “Took so long in the shower—were you secretly hard against the wall for ages and couldn’t finish?”
I ignored him, dried my hair, sat on my own bed with my back to him.
He chuckled, came over and sat beside me, thigh pressing against mine: “Stop pretending. That look you gave me last night—I still remember it crystal clear.”
My shoulders stiffened.
He pushed the velvet cloth toward me: “Let me show you something. I picked up the express delivery at noon yesterday while you were in class—custom-made, arrived in 48 hours. I chose the color. Thought it suited you.”
I turned my head: “Who said I’m playing this with you.”
He leaned closer, voice dropping like a whisper: “Last night you were hard and couldn’t sleep, jerked off three times staring at the ceiling and still couldn’t finish, right?”
I whipped my head around to glare at him: “You were watching me?”
“Not watching. You were breathing so heavily the bed was shaking—I’m not deaf.”
He paused, pressed the black key into my palm, skin to skin, burning hot: “I’ll let you hold my key for now. Simple condition—you lock up too. We hold each other’s keys. Whoever can’t take it and begs first becomes the other’s slave for a month. Play however you want—oral, licking, getting fucked, getting pissed on, public play…… anything.”
My breathing turned ragged: “……Are you insane?”
“Not insane. Just want to see you break.” He grabbed my chin and forced me to look up. “Think about it—locked during class, playing basketball, sleeping. Get hard and can only leak, pushed to the limit with no release. Key in the other person’s hands…… Beg me and I’ll unlock you for five minutes; if I’m not in the mood, you stay locked for running, cold showers, studying. Same the other way around.”
His eyes were bloodshot: “Scared? Then forget I said anything. But if you refuse, starting tomorrow I’ll jerk off in front of you every day until I fail, make you listen to me panting and watch me leak—but you can’t touch. How long do you think you can last?”
The dorm was silent except for the air conditioner hum.
I stared at him for a long time, palms sweating, gripping the key until it burned.
Finally, I heard my own voice, very small: “……Put it on me.”
His eyes lit up instantly, like a hunter watching prey take the bait.
“Good boy.”
He pulled me to his bed, sat me down, knelt, and skillfully pulled down my shorts.
He held the pink cage, turned it, checked it against the light.
“Relax. Don’t clench so tight.” He lowered his head, licked once to help me soften, then slowly slid it on.
Cold resin met burning skin. I sucked in a breath: “Hiss……”
“Endure it.” His voice was terrifyingly gentle as his fingers pushed each testicle into the ring. With a “click” the locking ring closed. He picked up the silver padlock, threaded it through, and locked it with a snap.
In that moment the world went quiet, leaving only the strange sensation of being fully restrained below—swollen, aching, no escape.
He looked up, eyes curved like crescents: “Now it’s your turn to help me.”
He handed over the silver-black cage, already half-hard and pressing against the bars. My hands shook as I took it, copied his method—licked it wet first, then slowly fitted it on.
He let out a muffled groan, knees buckling slightly.
Once locked, he hung the silver key back around his neck and pressed the black key into my hand.
Then he leaned down and whispered in my ear: “From now on, we’re lockmates. First day—good performance. Reward—you can sleep with my cage in your mouth tonight. Don’t spit it out.”
I didn’t speak, instinctively clenched my thighs.
The cage immediately tightened even more.
……I was already starting to regret it.
But what I regretted more—was that I was actually looking forward to tomorrow a little.
In the days that followed, on the surface we were still basketball buddies and roommates, but in private we were completely sick.
At 4:30 p.m., I passed the outdoor half-court and saw A Lin practicing alone. He wore his oldest black sleeveless jersey, armpits soaked through, sweat running down his pecs, the edge of his shorts darkened with sweat. Every time he jumped for a layup, the cage swayed inside his shorts. I could almost imagine it hot from sweat, pressed against skin.
I was about to pretend not to see and leave when his three-pointer went in and his eyes locked onto me at the same time.
“Yo, here to watch me bully noobs?” He wiped sweat and crooked a finger at me. “Come here. Help me pick up the ball.”
My legs felt like lead, but I walked over anyway.
Hardly anyone was on the court. He led me to a corner by the water dispenser, hidden behind an iron rack.
Drinking against the wall, water dripped from his chin onto the cage, then down his inner thighs.
He handed me the bottle, voice low and hoarse: “Help me wipe off some sweat. Use your hands.”
I glanced around, reached out, pretending to wipe his shoulder while my fingertips slid to the front bars of the cage.
Cold metal, burning skin, mixed with the musky-sweet scent of sweat and precum.
When I pressed with my fingertip, he groaned, knees nearly giving out.
“Gently…… fuck……” He grabbed my wrist and pressed it inward instead. “Go in a bit more. Touch inside.”
I slid my index finger through the gap and touched the head—swollen purple and soaking wet.
His breathing turned ragged, forehead pressed to my shoulder: “Tonight when we get back…… I’ll give you the key for a whole day. Condition is—help me suck it now, just once. No one can see.”
Laughter from juniors came from the other end of the court.
Head hot, I squatted down, pretending to tie my shoes, and brought my face close to the edge of his shorts. I licked the front of the cage once through the fabric.
His whole body trembled, nearly crushing the water bottle.
“……You actually fucking dared.” His voice was shaking.
I stood up, wiped my mouth, and lowered my voice: “Eight tonight. Kneel and wait for me. My turn to hold the key today. If you don’t behave, I’ll make you take a cold shower locked.”
He stared at me for three seconds, then suddenly laughed—both sleazy and pleased.
“Sure.”
He threw the ball at the hoop, swish, then turned toward the locker room, looking back to flip me the middle finger—actually a key-shaped gesture.
I stood there, legs too weak to stand. The pink cage in my pants was stretched to the limit; every step reminded me: you’re the same. No escape.
That night at eight, the dorm door locked from inside, lights off, only the faint glow of a phone screen.
I knelt in front of his bed. He sat with legs spread, the silver-black cage right in front of me.
“Open your mouth.” His voice was extremely hoarse.
I opened. He pushed the front of the cage into my mouth.
Metal cold, carrying a full day’s sweat and the musky sweetness of his leaking fluid.
I held it, not daring to move my tongue, afraid it would make him harder.
He panted lowly, fingers threading into my hair, gently pressing the back of my head.
“Just hold it like that…… don’t spit……”
His other hand touched his own cage, trying to rub, but only produced faint metallic clinks.
“Fuck…… so itchy…… want to cum but can’t……”
My throat tightened, saliva dripping from the corner of my mouth onto his thigh.
He suddenly pulled me closer, pressing the cage deep into my throat.
“Deeper…… yeah…… like sucking cock……”
My eyes watered, breathing heavy. The pink cage below ached from being stretched, precum already soaking a patch in my underwear.
He panted for a long time, finally let go, voice trembling: “Enough…… that’s it for tonight.”
I pulled off, lips numb, gasping as I looked up at him.
His eyes were bloodshot, Adam’s apple bobbing: “The key…… you hold it until tomorrow noon.”
He took off the silver key and hung it around my neck.
Then pulled me onto the bed and into his arms.
“Sleep. Sleep locked. Whoever wakes up hard first loses.”
I leaned against his chest, listening to his heartbeat. The two cages below pressed together, metal making faint sounds.
That night, I didn’t sleep.
Every morning erection was like reminding each other:
We were completely locked together now.
Whoever begs first is finished.
……But I think…… I’m already a little reluctant to unlock.
