I jump slightly as I hear the doorbell ring and head to the front door, confused as to who it could be. On the other side a smiling postman passes me a large cardboard box. I look at it confused as I sign the tablet, I don't remember ordering anything, I wonder what it is? Maybe it is something I ordered a while ago and then forgot about? 

Closing the door I carry the box to the kitchen counter and cut it open. Inside I see various items that immediately peak my curiosity and make my cock twitch. I pick out and go through all the items, a heavy metal collar, wrist and ankle shackles, chains, several padlocks, a large buttplug, a blindfold, a large ring gag, one that would allow for any size cock or dildo to easily gain access, and also make my jaw ache like crazy, and a tiny chastity cage, only about an inch big, somewhat roomy for me but small enough to do the job. Weirdly though I don't seem to see any keys to any of the padlocks, if i use them I'll be trapped in them. I stare at the items in the box, I don't remember ordering any of these. Were they sent by mistake? I check the label and read my name and address. Who sent it and why? 

I look inside the box again and find the receipt, nothing that gives me any further clues. I pause as I see something resting flat against the bottom of the box, the brown envelope almost lost against the cardboard, buried under the mysterious restraints. I pick it up and open it, maybe the keys are inside? I pull out a single piece of paper.

"Put them on if you dare." My cock twitches and my heart races at the idea of locking the restraints on without the keys, being completely helpless. Maybe whoever sent it will rescue me or maybe just use me? Or maybe this is some twisted prank and I’ll remain trapped? The thrill of the unknown only makes it more exciting, I love bondage but the issue with selfbondage is that you know when and how you'll be released. 

I shake my head, attempting to gain some sanity, and look around suspiciously as I force myself to close the box. The idea of putting this all on is crazy and ridiculous, yet weirdly tempting. I wonder who sent it though? Someone I know? Someone I've spoken to online? A complete stranger? A stalker? Are they watching me now? Why does that excite me more? I really need to control myself. As I think that, my hand slides under my trousers and I begin to playfully stroke my hard cock, letting out a small moan of pleasure. I wonder if they're watching me doing this? The thought of unknown eyes watching me pleasure myself and enjoying the show pushes me over the edge and my underwear is quickly soaked, although for fun I leave them on, forcing myself to feel and smell my cum soaked clothes as I get on with daily tasks, trying to ignore the mystery package and its challenge, one that is increasingly tempting and hard to get out of my mind. 

It's been hours now and I still haven't managed to stop thinking about the package, my mind unwilling to let it go and think of anything other than the restraints, the urge to put them on, even knowing that I wouldn't be able to escape, only growing more and more bigger, dominating my thoughts. I sigh, unable to focus on anything, every other task seeming dull and boring, only making the excitement of the mysterious package even more enticing. 

I slowly walk over to the box, still sitting on the counter, my heart beating faster with each step, as if drawn to it. Am I actually going to do this? 

Before my brain can stop me, I reach into the box and pull out the heavy metal collar, the cold hard metal immediately turning me on and making me smile slightly, as I bring it up to my neck, the steel closing tightly around my throat as I close the lock shut, trapping my neck in the heavy metal band. I panic slightly as I hear the click, as if only just realising what I've done, and pull on the padlock, testing it, as it refuses to open for me. 

Feeling my nervous heart beat excitedly and my cock twitch with enjoyment I quickly remove my clothes, stripping naked as I pull out the next item. Before my cock can grow any harder I slide it and my balls through the metal ring and quickly slide the tiny metal tube over my cock, squeezing it slightly as it resists. My heart races and my hand stays still for a moment as I hold the padlock, am I really about to do this? Click! Before I can finish thinking through my own question I close the lock, my now trapped cock reacting immediately as it strains against its new prison, one that I don't have the key to and my never obtain. Feeling a wave of horny frustration I let out a whimpering moan and pull on my now caged cock, almost immediately regretting my decision as it refuses to give my any freedom, crushing every futile attempt to get hard as my arousal grows. What am I doing? 

With my only hope for release now being the mysterious person who sent me the package I have no choice but to continue. I bring the large ring gag up to my lips and open my mouth wide, the gag barely fitting behind my teeth as it forces my jaw wide open, leaving it as nothing but a mute gapping hole, one unable to speak, only take anything giving to it, cum, piss, ass, cock, toes, spit, disgusting food and drink, my mouth is at the mercy of whoever finds me. I moan and mumble through it, drool dripping down my chin uncontrollably as I test out my gag. 

Next I pull out the buttplug and playfully slide it into my now open and waiting mouth, my tongue hungrily rolling over it as I lube it up. I moan as I slowly push it against my ass, stretching it open as the large intruder enters, filling my insides and making my cock strain even harder as it pops into place, my asshole closing tightly around the base, holding it firmly inside me. 

I then close the cold hard shackles around my ankles, linking them with a chain, reducing my movement and mobility, forcing me to take small steps as I pick up the remaining items and move to the hallway, kneeling near the unlocked front door, hoping that my mysterious gift giver will save me. 

Darkness consumes me as I lock the blindfold tightly over my eyes and leave myself unable to see anything around me or that will happen to me, adding another layer of thrilling and arousing mystery and suspense. In my now blind state I hear my heart beating as I playfully hold the final item, part of my mind desperately trying to reason with the overwhelming desire to lock them in place and completely seal my fate.  

Lastly I close the shackles around my wrists and lock chain linking them together behind my back. With one final padlock I loop the lock through both sets of chains between my wrists and ankles and click it shut, preventing me from getting off my knees. I moan and pull on my restraints, my mind only now realising the full stupidity of my actions, while my cock strains painfully against its cage, reminding me of why I did this to myself, as panic and desperation flood my helpless bound body in an insane mixture of fear and arousal, one I’ve never managed to achieve on my own before, as numerous thoughts, ones I should have thought of already, fill my mind. 

I hope they were watching? What if they weren't? What if I'm trapped like this forever? What if I'm never found? What if someone else finds me? What if there is more than one? What if I'm never released? What if I'm used and left bound, to be found by others I know? What if they sell me into slavery? What if they torture me? What if they film me? What if they take me with them? Will they keep me as a sex slave? Painslut? Pet? Whore? Prisoner? Cuckold? All of those? I wait, struggling in my restraints, the plug deep in my ass moving as i do, causing my cock to strain, the uncertainty of my fate both filling me with dreadful fear and horny arousal.
