I roll over in the muck covered floor of my home as I wake, feeling the familiar feel of the filth covering my unwashed smelly body, a slight groan exiting my mouth as I feel my morning wood painfully crushed against the 1 inch chastity cage locked around my cock, one lost under the layers of fat, always buried by my large belly and thick thighs. For a moment a small part of my mind asks how I ended up here, why did I choose this life? I once had it all, I inherited so much wealth, a mansion, and so much time to do whatever I want, but with came so many expectations, with the best education money can buy I was always expected to get full marks and the highest grades, with the best instructors I was expected to excel at sports,  music and other activities, with a family of successful businessman I was expected to do just as well if not better. It was all to much, I crashed out, I barely made it through basic education, it was only money that got me into university, my degree basically paid for, but it was there that I met someone, someone who unlike me was everything my parents wanted, everything I wasn't, unlike me he had no money, he was struggling to even pay uni fees and rent and would leave in huge debt and no money for investment. So I made him a business deal, which at the time seemed really good, he could have access to my money and take on my business roles, he can move into my mansion, in return I'd stay there and keep the place tidy and be the face of the business, my family name and connections being my greatest asset. 

My role was easy, especially as I could afford staff to clean and tidy the place and I'd occasionally show up to social events, while my parents thought I'd finally become everything they wanted, I was actually sitting on the sofa eating junk food, while my partner did all the complex dealings. Then one fateful day my parents died in an accident and everything changed. 

5 years ago: 

I sit lazily on the sofa, the cleaner quietly doing my chores for me, leaving me free of any responsibility, the one business deal I did and it was a good one, one I doubt my parents would be proud of but it has made me millions, my business partner really does know his way around the markets, far more then I ever have, I would argue that I am being resourceful. 

I hear the doorbell ring out through the hallway of the mansion and the faint sound of my butler opening the door, quickly followed by the faint sound of it closing again. I turn as my butler enters the room and hands me a package.

"A delivery sir." I take it and rip open the packaging, dropping it uncaringly onto the freshly cleaned floor, not noticing my cleaner roll their eyes in irritation. Reading the card I see that it is from my business partner.

"To celebrate another year of our arrangement and exciting news, I sent you something I know you'll enjoy. Both our futures are soon going to change for the better." I put down the card, curious about what the exciting news is, did he make us even more money? Whatever it is I return my focus on the box, opening it to find chocolates, ones that I quickly dig into. 

I feel sleepy as I slowly open my heavy eyelids. I must have fallen asleep on the sofa or something, I don't really remember. But why do I feel cold? Why do I feel discomfort in my crotch? Why does my body feel strange? 

As I open my eyes I see what looks like the ceiling of my basement, why am I here? As my eyes adjust to the dull light I see my business partner standing over me, am I on the floor? Why am I on the floor? And why does it fill so gross and wet.

"Hello piggy, I'm glad to see that you've woken up from your little nap, I knew you would enjoy those chocolates." The chocolates? Was there something in them? I stare up confused at my partner, his eyes rolling in response.

"You really are thick aren't you. The chocolates, the ones I bet you didn't even hesitate to shove into your disgusting mouth, were drugged. You've been out for several weeks while I made some arrangements and slight alterations to our deal." What? He drugged me? What changes to the deal? Why is he doing this? Everything was going so well. I watch as he lowers himself down to me, still staying some distance away.

"Are you confused piggy?" Why does he keep calling me that? I try to speak, only noticing comes out, only a sound that vaguely resembles that of a pig. 

"That's right piggy, oink for me." I try to ask what is going on but only keep making oinking and squealing noises like an animal.

"Calm down piggy, while you were unconscious I made a few modifications to your body to better fit your personality and new position, like your vocal cords, you can no longer speak, only squeal like the fat ugly pig that you are. If you look down you'll see what else has changed." I fearfully look down at my body and freeze in shock and horror, my hands now completely fingerless, looking like round useless feet, and my legs, what was left of them ending at my knees, or where my knees should be, leaving two short stubby legs. I also see a small shiny object where my cock should be, the cause of the painful discomfort. I look up in confusion as my partner holds up a small mirror, showing the rest of my modified body, one now completely hairless, including my head, showing my now misshaped and floppy ears, that stick noticeably out, and my misshaped squished nose, and what looks like a small curly tail coming out of the base of my spine.

"You like your tail? I used the skin off your removed legs to make it, a piggy needs a tail after all, I'm very proud of that, while it doesn't have movement you can still feel with it, so behave or I might have to pull on it." I shakily try to get up to all fours, struggling to balance my new body as I try to process everything, staring at my partner, still confused about what is happening and why. 

"I'm afraid I have some bad news for you. Your parents had, let's say, a little accident, that's what the authorities think anyway. They left you everything of course, even though you never deserved it, never used it, you had every advantage in the world and you couldn't be bothered to do anything. Unlike me, I had to work my ass off every day of my life to even get a fraction of what you have, I had to pretend to be honoured and grateful for your deal, one that makes me do all the work in exchange for earning half the money, while all you do is pose for photos and attend parties. Thankfully you never read the documents I slowly had you sign, not that you'd understand them if you did, you have no idea how much control you willingly handed to me. I control all your finances, I own all tour businesses, I have control over your medical decisions, I even own your property, basically I own you. The only thing keeping you safe were the only people who ever cared about you, who would check in on you, check in on their investment,  generally be a nuisance and obstacle to my goals, but now they're sadly gone, in that terrible unfortunate accident, there is no one who will come looking for you, no one to save you from the fitting fate you deserve." I stare in complete shock, this can't be real, this can't be happening, he can't get away with this, I'm rich and powerful. My partners face looks down at me with mocking concern and sympathy.

"Unfortunately for you I can get away with this, I already have. Everything you or your family own is legally mine, I legally own all the businesses, I even legally had you modified, I own you piggy. In the rare case that anyone actually comes looking for you, I'll say that you are spending time to grieve, that is until I organise another unfortunate accident,  one so soon after his parents, then you'll definitely be undisturbed down here in your new home." Defeated and realising that this is my fate, tears begin to form in my eyes. I feel his hand stroke my bold head, his face still mocking me.

"Don't be sad piggy, I think you'll enjoy your life of being a lazy slob and living in your own filth, it's not really much different from how you lived before." With that he smiles and gets up.

"Now I have important things to do, money to spend and a life to live and enjoy. You have fun down here in your new home piggy, I'll have the staff bring you your dinner." With that he turns and leaves, walking up the basement stairs, ones that I couldn't climb in my new state, the door slamming shut and locking, the sound echoing in my mutilated ears, sealing me into my new muddy home, my very own pig sty, hidden away underground, where no one can find me. 

Present day:

I roll onto all fours, my large flabby belly getting in the way and making it more difficult, as I stand I immediately piss into the mud beneath me, feeling a rumble in my stomach my piss is quickly followed by my shit splashing into the putrid stinking muck below, mixing in with the rest of the filth, which much to my disgust I've long gotten used to smelling, walking in and having stuck to my skin. 

I hear the basement door open and in the dim light see the cleaner walk down the stares, his face always showing how much his enjoyed his task of emptying the food waste into my feeding trough, happily watching as I humiliatingly waddle over and hungrily eat the leftovers and discarded ends of vegetables, fruit and veg peal, fatty meat, fat, grease, oils and other horrid things that no one else wants, not that I have a choice in eating it, the shock collar around my neck there to discourage any misbehaviour and with no way out if my situation I have little choice in what I eat, only what is given to me. 

I feel the cleaners hand stroke my dirty bold head, the sole human contract that I have, my cock strains as I enjoy it, desperate for any physical contact. 

"Good piggy, eat all that up, I'll be back later with the condoms from master's bedroom, I'm sure you'll enjoy that treat, and if you're a good piggy and are lucky you might get a fresh helping as well. See you later piggy." With that he leaves, I continue to eat like the pig I am, part of me unable to resist being excited for my meal later.
