I look at the shelves of interesting items, unlike the other shops this one is new in town, my reputation hasn't reached the shop owner yet. Seeing something I move over to it, the shiny golden metal and fiery red jewel glinting almost unnaturally in the sunlight, I look at the strange collar, one with a ridiculous price tag and even more ridiculous name, and they call me the criminal, sure I'm a serial shoplifter but this is daylight robbery, that much for some pretend magical item, who falls for this stuff? 

I slowly slip my backpack down and turn my head to look at the counter, the shop owner behind it busily serves one of the many people he cons into buying this rubbish, they just sold some dried plants for goodness sake. As I keep an eye on the owner I slip the collar into my backpack and put it back over my shoulder and continue to move around the store, pretending to look curiously at various other objects, none of them really catching my eye, plus one missing item is easier to miss, I'll only draw attention to myself if I take to much, I can always come back but if I do I’ll have to buy something to not draw suspicion. 

I smile politely at the shop owner and head to the door, opening it to a gust of fresh air, one blowing away the funky smell of incense. The bright sunlight and fresh air disappear as I step through the doorway, the world suddenly going dark and silent. 

Confused I look around the dark space, the door I came through no longer existing. How did I get here? Was that more than just incense burning? If so this whole magic thing is beginning to make more sense. 

I feel around and try to find anything in the dark and seemingly endless void. 

"Looking for something?" I turn to see the shop owner calmly looking at me, his face that of a helpful member of staff. 

"Where am I? What have you done to me?" He continues to smile at me.

"I have done nothing, you are here due to your own actions. Nothing can leave the store without my permission." 

"But I haven't taken anything!" The shop owner looks over his glasses, showing that he isn't buying it and is slightly insulted that I'd even try that. I sigh and pull out the collar.

"Here, take it." I stare at the collar, part of me not wanting to give it up, more than my normal dislike for giving back stolen items.

"Why don't you try it on? Maybe you'll like to buy it?" Buy it? I couldn't afford it. But I do like the idea of putting it on. I look at the gem, it seems to still be catching the sunlight in the dark and shadowy lightless room, looking almost as if it's glowing with a burning passionate fire. What is happening to me, why don't I just give it back and get out here, wherever here even is? Without fully realising I slowly bring the collar closer and open it. Part of my mind tries to tell me to stop but the urge to put it on is overwhelming. Why do I feel like this? I feel the metal as it closes tightly around my throat, the jewel glowing a bright fiery red as the band of metal fuses and smooths into one ring of solid metal, my mind immediately filling with strange desires and eagerly awaiting instructions, my own mind unable to decide or even think of what to do, my mind feeling strangely calm, peaceful and content. 

"How does it feel?" The shop owners words sound clearer, almost as if he is speaking directly into my ear. For some reason I feel compiled to answer and to do so honestly.

"It feels great master." Did I just call him master? Why did I just say that? The words just slipped out without thinking.

"Good. And what do you desire?" What a strange question, to get out of here obviously. But is it? Is that my desire? No, what am I thinking. I struggle as a barrage of thoughts enter my mind, none of them involve leaving, the opposite, staying and serving my master, pleasuring my master, being bound in bondage. Any thought of leaving, of disobeying, of displeasing my master fill me with guilt, as if I’d done something unforgivable and wrong, almost painful, like I’ve betrayed my beloved master. Fear and confusion flow through my mind, before being drowned out by other more pleasant thoughts of serving my master. Why am I thinking these insane thoughts and why am I so hard and horny? 

"My desire is to serve my master." What did I just say? Why did it feel so right and natural? I struggle to fight back from whatever is happening to me.

"What is going... going... on?" I manage to force out the words, feeling less easy than anything I've ever said, having to focus on every word before it slips from my mind, drowned out by my growing need to please my master and my ever growing desires and lust.

"Not everything in my store is cheap rubbish sold to the gullible, some are actual magical items for those who truly know what to look for. You should have read the details of what you stole. It isn't just a pretty piece of cheap jewellery. It's a special collar, one that amplifies a person's natural submissiveness, it seeks out and calls to those who are submissive and helps them to become better slaves and once put on, the wearer can not remover it, only the owner can. As the owner of the collar, you have willingly become my slave by putting it on." 

"W... what! T... take... i... it... o... o... off!" The words barely leave my lips and almost breaks my heart as I say them, as if I never want to leave my master and have my collar removed, part of me is relieved as my master shakes his head.

"I would but you were trying to steal from my shop and clearly are in need of punishment and guidance. I'll make sure to give you both as I train you to be my slave and assistant, a sorcerer needs a familiar after all." What, no, he can't do this to me! Yes he can, he is our master, of course he can do whatever he wants to us, he is so wonderful for making us his slave and familiar, I will do my very best to please him and show him gratitude for such an honour. What, no, stop thinking like that!

"First things first. Remove you clothes, you want be needing them any more." I struggle to fight back but my desire and urge to obey his instructions quickly overpowers me and before I know it I'm removing my clothes and standing fully naked and exposed in front of him.

"Put this on." A small metal object floats into my hand and I stare at it for a second before I understand what to do, I am supposed to put this ring behind my balls and then slide this tiny tube over my cock. Wait, no, don't…! The click of the lock rings in my ears as I seal my own cock away, the crushing feeling already noticeable as it desperately tries to get hard, pressing painfully against the walls of its new prison, my sexual desires growing even greater as the need to get hard starts to drive me insane.

"Good slave." I smile and feel joy at the praise from my master, the pleasure washing away any doubts and fears, I did good and that's all that matters, master knows best.

"Follow me." I do as I'm told and happily follow my master out of the dark void and back into the shop, where I'll remain and serve him dutifully, loyally and without complaint or hesitation. 

Epilogue: 

I moan and struggle in the tight ropes, the rope only getting tighter as I wiggle and twist, my mind insane with frustration and horny lust, the vibrating plug in my ass endlessly teasing me and causing my cock to strain desperately against its eternal prison, unable to cum without permission, no matter how close to the edge I get, all while my master sleeps peacefully. My eyes struggle to focus on the clock, nearly time for his wake up call, maybe then I can gain some relief although normally he just wants a blowjob in the morning, to sleepy to do much more. The thought of his delicious cum makes my empty stomach rumble, it's all I live off since wearing the collar, it's magical curse making me undying, my life bound to my master’s, and punctually immortal so long as I consume cum on a daily basis, either orally or anally, it doesn't matter how it gets inside me, as a result master never feeds me, the only things I swallow, aside from cum, are his piss, whatever I clean from his ass and feet, mess he stepped in off his shoes and very rarely scraps of his food or gone off food he forgot about and needs disposing of, as a result I'm constantly starving but also never require toilet breaks so can spread more time serving my master. 

I hear the alarm ring and the ropes reposition themselves, allowing me to move my legs and slide under the covers to suck my master's cock and receive my breakfast and remain his eternal slave, his dutiful familiar, his grateful assistant. I moan hungrily as his cum fills my mouth, the taste is better than any food, I'm not sure if my taste was altered by my collar or if I have become addicted to it over time but I don't really care as I swallow it down, gratefully receiving his gift, and feel the pleasant magic grant me an eternity with my master. 

I climb off the bed and kneel down, the ropes binding my legs, keeping me kneeling, not that I would dream of moving, although the feel of the ropes securing me is comforting, plus I like how much seeing me bound pleases my master, he always enjoys the sight of me in my bondage. I watch patiently as my master wakes, his limp cock sliding into my mouth, quickly filling it with his warm piss, which I gulp down thirstily, making sure to not waste a single drop, honoured to receive his gift. 

I feel the ropes leave me and my plug finally stop vibrating, giving me a chance to focus on my daily tasks, although my swollen balls and denied cock are a constant distraction, it is easier to ignore without the constant stimulation. I follow my master out the bedroom, eager and content to start the day, make his meals and work in the shop, then help him with any spells or potions he wishes to do, afterwards he will hopefully reward me with a good fucking before I'm once again left bound for the night, made to spend hours teased and tormented while I watch him sleeping peacefully, before starting yet another meaningful and purpose filled day serving my master.
