so i meet up with this guy who's into chastity. i bring out the tiny metal cage, watching his eyes widen with a mix of fear and excitement. i make him strip naked, his cock already starting to harden. i slip the cage over his dick, clicking the padlock shut with a satisfying snap. he groans, his cock straining against the confines of the cage, but it won't let him get fully hard.

i kneel down in front of him, running my hands up his thighs, feeling his muscles tense under my touch. i lean in, my breath hot on his balls, and start licking them slowly, teasingly. he's moaning, trying to thrust his hips, but the cage keeps him painfully confined. i can see his cock trying to erect, the veins bulging, but it's trapped, the metal digging into his flesh.

"you like that, don't you?" i whisper, my voice low and sultry. "you like feeling my tongue on your balls while your cock is trapped?" he nods, his breath coming faster, his body shaking with desire and frustration.

i start to punch his balls, not too hard at first, just enough to make him gasp. he's writhing, the pain and pleasure mixing in his eyes. i punch again, harder this time, watching his cock try to erect but failing, the cage causing him agonizing pleasure. his balls are turning red, swollen from the impact, and it's making me so fucking wet.

i stand up, grabbing his balls in my hand, squeezing them tightly. he groans, his body convulsing, the pain and pleasure overwhelming him. i slap his balls hard, the sound echoing in the room, his cock straining even more against the cage.

"you're such a fucking slut," i hiss, my voice filled with dirty lust. "you love this, don't you? you love the pain, the frustration, the feeling of being trapped." he nods, his breath coming in ragged gasps, his body covered in sweat.

i give his balls one final, brutal punch, and he cums, his body spasming, his load leaking out of the cage, dripping down his thighs. i step back, admiring my handiwork, his balls red and swollen, his cock painfully confined, aching for release.

i lean in, kissing him hard on the mouth, tasting his sweat and desire. "thank you for letting me torture your fucking balls," i whisper, before walking away, leaving him there, spent and satisfied, his cock still trapped, aching for more.
