"So, birthday in a week, what you want?" I try to think, nothing coming to mind, well one thing but I can't tell him that, sure we're best friends, have been for a long time, we don't hide anything from each other, he even knows that I'm into bondage and bdsm, but still, the idea of telling what I really want, what I've wanted every year since I was an adult, would be embarrassing. What would he think of me? 

"I don't know myself, I guess it gets harder the older you get." He shrugs in response. 

"Well I guess I'll be saving some money then." We both smile and continue our time together before he has to go to work in the evening. 

I walk in and slump down on my sofa, my friend's question lingering in my mind. What do I want? I allow myself to think about what I truly want, my cock getting hard, pushing into my trousers as I picture myself naked with a heavy metal collar locked around my neck, a thick chain hanging from it like a leash, my hands cuffed or shackled helplessly behind my back, my cock straining against the small steel chastity cage it's trapped inside, while I'm forced to take my master's cock in my mouth and ass, choking on his cock, before he roughly slams it inside my ass, my saliva the only lube I get, his cock thrusting balls deep, filling me with his warm cum, his now dirty cock sliding between my lips as I'm made to clean it, to taste my own ass and his cum, before being left chained up by my leash, kept bound and locked away in my cell like a prisoner or maybe a cramped cage like an animal. I moan as I undo my trousers and gently stroke my freed cock, my mind enjoying being free to indulge my fantasies, ones I've had for so long, unfortunately never meeting the right person to make it a reality. 

Maybe it doesn't have to be just a fantasy though? I remember the website that I'd accidentally stumbled upon, I've no idea how I found it, I was deep in a late night fantasy rabbit hole, watching porn, reading stories, looking at images, reading captions, and I found a website, one that auctioned slaves. I immediately clicked off of the dodgy looking website, but it has stuck in my mind. What if I put myself up on their, put myself for sell, finally find a master, finally be enslaved, finally realise ny dream? No, that would be crazy, it's an insane idea, they'd be no way back, I'd be a slave forever. My cock twitches, as if that fact somehow only makes it more appealing. I stop stroking myself, trying to clear the ridiculous idea from my mind. 

I stare at the screen of computer, the website in front 9f me. What am I doing here? We're only having a look, nothing else, just relieving my curiosity. I tried so hard to get the idea out of my head, I even did all my housework and searched for jobs, but no matter what I was doing it refused to fade, even as I tried to sleep, bringing myself to multiple orgasms in hopes of relieving myself. Now I'm here, exploring the website, learning how you would put a slave up for auction, putting in what I'd write about myself, that I'm obedient, loves bondage, happy to be left alone in a cell or cage when not needed, not fussy about food, eager to please, loves cum and piss, can be locked in chastity if wanted. I can even select when the auction ends, I pick my birthday, imagine what a great birthday that would be. I even took a picture, my body perfectly shaved and on full display. I then look at the starting price, what price would I set for myself, would I go high,  hopefully get a rich master, or do I go low, risk becoming a cheap whore or owned by someone who lives in a cheap house, unable to afford to feed me anything other than scraps. I feel my cock harden at the latter and select a price lower than others on the site, at this it would guarantees my purchase. 

Part of my mind screams at me as I'm lost deep in my fantasy, my mouse slowly moving over to the submit button, before I can stop myself I hear the click as my sale goes out to anyone, I freeze as I see myself up for auction, nothing but an item for sale, a product to buy, the thought of being nothing but an object to be brought makes me so horny, my mind forgetting the situation that I've just put myself into for a moment. Realisation only returns to me as the screen suddenly updates, someone has bid on me, my purchase now inevitable, my sale locked in, to cancel it I'd have to pay the highest bidder and I don't have the money, not until I get paid for myself anyway. Slight fear fills me. What have I done? But I also feel a strange thrill and excitement. I wonder what my master will be like? Will they be kind or cruel? Will they treat me like a person or like an object or animal? Will i be used solely for their pleasure or to service others to make him money? Thousands of thoughts flood my mind, some scary, most arousing. 

I pace around my home, my mind racing, my heart beating fast, my body overwhelmed with fear and excitement, my auction has ended, my sale has been approved, I even got a message telling me that I will be picked up in less than an hour, including instructors on how I should be ready. I stand naked, my cock straining inside its cage, one that it my never escape from, it was hard to resist on last orgasm before locking it in place, but part of me is sure that I'd accept my fate better if I remain horny, so I kept myself denied. Only now as I wait am I finally trying to figure out how to get out of this, all to late, my new master will be here in a few minutes. I could run away, left my old life behind? But then what? Find a new home and be left with my desires unfulfilled? There's a reason that I did this to myself, the truth is that deep down I want this, this is who and what I am. I wonder how my life will be from now on, who my master is, as I wait for them, my first taste of my life of servitude, waiting patiently for my master. 

I freeze for a moment, overwhelmed slightly as my doorbell rings. I shouldn't leave my master waiting, i should make a good first impression. I force myself towards the door, my hand shaking as I reach out my hand, as I grip the door handle I note that this is it, the last opportunity I have to back out, to run away, to get out of this. I grip the handle firmly and push those thoughts to the back of my mind, no, this is happening. 

I open the door, only to feel suddenly embarrassed as I see my best friend standing outside, my best friend who can see my completely naked body, one with a shiny chastity cage locked around my cock. 

"Happy birthday!" He holds out a wrapped present, as if he isn't seeing anything humiliating. Confused, I take the gift, it feels heavy beneath the paper. What has he got me? 

I begin to unwrap my gift, wanting this humiliating and embarrassing situation to be Iver before my master comes to collect me. I tear at the paper, revealing something shiny, something round, a collar? I stare at it confused. Why has he gotten me a collar? 

"Happy birthday, slave." I look up at him confused. What did he just call me? 

"I saw your auction and knew exactly what to get you for your birthday." I stand still confused and feeling slightly embarrassed. Am I to be his slave? 

"Well, put it on, I want to see how it looks on you." I obey my new master and open the heavy steel collar, bringing it up to my neck, closing it around my throat, the cold metal noticeable, as it clicks shut, locking to me, sealing my fate, marking me as owned property, my cock straining in it prison, smiling as I feel a sense of completion, as if this is right, as if I'm finally who and what I'm supposed to be. 

"That looks perfect." Before I can say anything he pulls out a heavy chain and locks one end to my collar. 

"Come on slave, time to get you to your new home, I've got my basement all set up for you." I feel the tug on my leash and without any choice, I obediently follow my best friend, now master, as I'm led away from my home and old life, to be taken to my new home, to begin my new life as a slave, excited to finally live my dream fantasy, eager to show my new master how happy I am and thankful I am for my birthday present.
