I hear the heavy door of my cell slam shut and lock, securing me inside my small home, one I've been forced to live in for months now, ever since I was tricked and enslaved, my master luring me to his home for some kinky fun, only to trap me as his slave, imprisoned, naked, locked in a painfully small chastity cage and a heavy tight metal shock collar, one that prevents me from leaving. 

I wait patiently, making sure that my master has left before I move my bed, and removing a small grated panel covering an air vent in the wall, reaching inside, hoping that master hasn't found it when checking my room. Relief flowing over me as I pull out the locked box, the one my keys were placed inside, freedom from my cage and collar hidden away inside. My cock strains in its prison, as if knowing that release is so close, as I try yet another combination into the lock, for over a week now I've been slowly trying to open it, desperately trying to gain access to my freedom. My master accidentally left it unattended while I was left alone to clean, my shock collar keeping me in line and preventing me from trying to escape, any attempt to leave the property would cause it to shock me until I drag myself back or my master saves me, and any attempt to speak shocks me, making it impossible to phone for help, besides I can't leave while my cock is locked away or without any clothing, but removing the collar will make the rest easier. I quickly took the box and hid it in my cell before returning to my chores, tidying the house, trying to resist the urge to immediately start trying to unlock it, instead keeping it hidden, focusing on my duties and avoiding punishment, until it is safe to try and obtain my freedom. 

I stare at the box, I haven't tried this in the last day or so, part of me to freighted to succeed, not from my master punishing me, but of what it could mean if I do gain my freedom. Another part of me though finds it hopeful to try, after a whole day of pretending to be an obedient slave, of serving my master, the master I love and obey, I can try to obtain my freedom. How can I not want freedom? To escape? What will I do once I'm free? What will I do without my master? What would be my purpose? How will I find meaning and fulfilment? No, I need to get out of here, the longer I stay the more my mind will be trained and conditioned into being his slave, the slave I'd always fantasised about being, a fantasy part of me still seems to want, one that my master has given me. 

I look at the keypad, trying to remember the various combinations that I've already tried. Should I come clean to my master about this? What if he finds out? 

I slowly push the buttons, a strange mixture of fear and hope fill my conflicted mind. Desperation grows as the screen reads incorrect, I only have another two attempts before the input locks again, preventing any further attempts for 12 hours. My hand shakes slightly as I input another code, incorrect. Part of me feels like I'm being watched, I look around in fear, worried about being seen by my master but also as if deep down I know I'm doing something wrong. No that's what he wants you to think. I put in another code, incorrect. Disappointment and relief come over me at the same time as I hide the box back away, remaining trapped in my cell, the crushing metal of my cage and the tight heavy collar around my neck feeling more noticeable in my failure. 

I lay defeated on my bed, trying to ignore the crushing pain in my crotch, a sense of guilt coming over me, one I hate feeling, one I deserve for betraying my master, maybe I should tell him and beg for forgiveness. I close my eyes, I better get some rest, I have a busy day serving my master tomorrow, doing chores and hopefully serving him sexually, as I have every day and will do every day if I don't unlock that box. Part of me seems to like that knowledge, I feel scared knowing that deep down I find comfort in that fact, that I will never leave, that I will always be serving my master, that I have purpose and value as his slave. 

Epilogue: 

I watch the screen with amusement, as I watch my slave grapple with themselves before making another attempt at unlocking the box. A box that they believe holds the keys to their freedom, ones that would unlock their collar and cage. They aren't in there, not any more, I destroyed them a month ago, they're never getting free or leaving this place, eventually they won't want to, once they accept that this is were they belong. I don't feel bad for him, I know this is what he really wants and desires, he came to me, told me his fantasies, once he has been conditioned to never live out, until my gift to him, before hand he lived a meaningless and empty life, I have given him everything he ever wanted and soon he will understand and be grateful for my kindness. 

The box is a test, eventually they'll stop trying, they are already slowing down on attempts, some days they don't even try, and when they do try they clearly feel guilt at their actions. If they give up and forget about it or tell me about it, they pass the test, however if they continue and actually manage to get inside the box, all they'll find is a note from their master, one that tells them how disappointed I am in them and that I've always known exactly what they're doing, that the keys they seek no longer exist, and that they will be punished for their actions. 

As much as I want them to accept their life and place as my slave, part of me wants to see their face and expression as they finally unlock it, to see their hopeful joy at finally succeeding, only for it to suddenly be replaced with fear and dread, all hope lost as they learn the truth. I can't help but smile at the thought of them opening the box and how fun it will be to finally break them.
