Jeff's mom was babysitting the next door neighbor's kid, who was less than a year old. Jeff thought, as odd as it maybe, to turn into a diaper. He changed the timelimmit to 48 hours, and clicked the Diaper option.

Jeff felt a tingling sensation, and then felt himself shrinking. When he was only a few inches tall, he felt his organs mushing together until they were nothing. His legs and arms reached back behind his back, molding together. Two holes formed beneath him. He watched in a nearby miror the last of his transformation. What he saw what looked like a diaper, whith flesh colored skin, and a face. But soon he saw his flesh become white, and his face began to fade into his face. Eventualy, all that was left was a diaper.
 

Jeff didn't hear his mom so much as feel the room shake as she walked into the room in a hurry. Phone on one side of her head cradled against her shoulder and  carrying his youngest sister in her arms.

"I gotta go," His mom said in an exhausted tone, "I'll be in to work as soon as I gotta find a new sitter, my current one canceled last minute." She hung up the phone and tossed it into a pile of towels as she placed his down on the changing station next to Jeff.

And He could smell his sister. It only took his mother a few moments to undress and clean up the infant and tossed the dirty diaper into the special pail they had for it.

Suddenly he felt him self being slid over and underneath his sister her privates right in his face. The smell wasn't as bad now after she was cleaned up with talc and dried.

With a sharp shock he felt the safety velcro lock him in place and he was lifted off the table and placed on the floor

Nina (his baby sister) crawls toward her toys. Once she gets near them she sit and start playing with them pressing him against the floor. She giggles and babble happily as she plays with her toys and he is forced to listen to all this which gets annoying after a while. Jeff really wonder what can be so exciting in randomly moving various shapes and forms around. Nina occasionally moves around causing him to twist and tug uncomfortably. But he can't speak or move in any way. Jeff got no choice but to bear with it and the worst is yet to come.

Perhaps this was not such a good idea he begins to think. Things will certainly get nasty (to say the least) when she finally "use him". He can already see himself at the bottom of the diaper pail waiting to change back. The more he think about it the more he wish he'd pick something else. Jeff begin to hope that all that twisting and tugging will somehow make him come off allowing him to escape the fate that usually awaits diapers. But unfortunately he is well designed and his arms and leg acting as the diaper's tabs holds him firmly into place.

Jeff wonders how long she can keep him clean. Considering that Nina was just changed he think that maybe she wont "go" for a while and perhaps he'll change back before she does. But then he remember that the timer was set to 48 hours. He doomed himself from the get go... Even if he had not been worn immediately, there would have been plenty of time for his turn to come and then some. Jeff feels like crying as he realize that there is no escape. "I'm definitively going to get soiled" he think hysterically.

As if on cue, he feels a warm liquid splashing against his face. He feels like his entire face is submerged in pee as it start to puddle in the diaper quicker than it can drain threw his mouth. His lips acting as leg guard making sure not a single drops leak outside. "OMG !! IT'S HAPPENING !" Jeff thinks in panic. The pee seems to make way to his stomach before progressively being absorbed by what feels like his tongue. The taste is awful and just wont go away.

Seems like the surface layer of the inside which is supposed to keep the gel beneath it is his face and the countless tiny holes in it allowing pee to pass threw act like is mouth. The thin sac containing the gel powder is his stomach. The gel powder itself (which ultimately absorb pee locking it away in a semi-solid form) feels like his tongue but is really all his vital organs (including his heart and brain). The pee is slowly being absorbed and fused with his inner self. Jeff is somehow conscious of all this and his horrified as he feel his body absorb more and more pee regardless of his will. This continues until his sister is finally done and the pee finally soaks all in leaving her skin almost dry.

Nina kept playing without a care in the world seemingly unaware of what she just did. Yet she was unconsciously relieved and satisfied. Enjoying the warm squishy feeling that her brother was now giving her every time she moved. Jeff on the other hand was going mad. The awful taste grew exponentially as more and more pee was gradually soaking in. By the time all the pee was finally absorbed, the taste was overwhelming and was not showing any signs of fading. Seems like the taste was there to stay.

Jeff lost track of time. The annoying giggling or the uncomfortable twisting and tugging did not mattered anymore. All he could think about was that foul taste. How long have he been enduring it ? It felt like years had past already. But it was obviously less than that. "48 hours of this... what in hell was I thinking !" he reflected. "A diaper ! Of all things a diaper ! It's going to be fun ! Smart Jeff... real smart" he scolded himself in his desperation.

Eventually, he feels himself behind lifted into the air and carried away as he hear is mother say "Times for dinner sweety". Moments later Nina was in her high chair and her mother was feeding her. Jeff could somehow hear strange and creepy gurgling sounds coming from his sister. Being strapped around her so closely, he could easily hear what was happening inside her body. He was starring at his sister's ass in profound disgust. He have just been reminded that as miserable as he is now, things could still get much much worst unless his sister was changed soon. Unfortunately for him, his sister did not seem to mind her wet diaper one bit. His mother always bought high quality diapers that did great at keeping babies' skin dry. No particular design was selected, so the Chronivac apparently copied the design of the surrounding diapers so that he would fit in perfectly. The baby powder was also helping with residual moisture. Increasing his sister's comfort. Jeff's sister would probably need to pee some more before she start feeling uncomfortable. The simple thought of having to absorb even more pee further intensifying the taste made him want to throw up.

Unless something else happens first he thinks starring at his sister's asshole again. Then it started to throb and twitch a bit to Jeff horror. "GOD NO ! not yet ! Not so soon !" He thought hysterically. She only let out a fart as if answering his prayers but still giving him a small preview of what's to come. Most of the air was expelled to make room for the dreaded gas. The smell was putrid and powerful. The water tight diaper was doing a good job of keeping the smell contained prolonging Jeff's ordeal. Yet beside all this, Jeff was still grateful that it was just a fart. A fart would eventually go away. Then he heard more gurgling sounds as her mother was still feeding her. The sounds seemed scarier than ever. He felt that the food was not intended for his sister, but in fact for him. Like his mother was helping her prepare poop for him.

Jeff couldn't take it anymore. He wanted to get out of this nightmare. He would kill himself if he could. But he was a diaper now. Faithfully fulfilling his duty whether he likes it or not. He would contain all his sister's wastes until his mother finally discard him. There is nothing he could do about it. That is just how things were. He'll just have to wait until the 48 hours are up and then he could try to forget everything about this. Still, he hoped his mother would change her before she gets to use him further he thought. Then Jeff panicked as her ass twitched again letting out an other fart. Then Jeff realized something. When people start farting repeatedly it often means that they are about to poop. "Please mom, change her already ! I mean she have been wet for a while already. Come on !" Jeff begged in silence.

Then he felt himself lifted in the air again. Her mother was done feeding Nina and was now returning her to the living room floor. She returned to her toys and played some more. Some time later, she got up on hands and knees and started to crawl toward the TV. The opening song of some cartoon show had caught her attention. Then her asshole started to twitch and throb again. "Great... an other fart" Jeff thought momentarily diverting is attention away from the permanent taste.

But after farting again her asshole continued to twitch until it suddenly pushed open outward letting Jeff hear strange cracking and squishing sounds (which are somehow familiar). He watched, completely horrified, what seemed like the tip of her first "log" pushing it's way past her asshole directly toward him. "Oh please Nina ! Hold it in ! I'm begging you !" he thought. But to his great dismay, she adjusted her position and then grunted slightly instinctively trying her best to push that thing out instead of making any effort to hold it in. Her innocent cruelty made Jeff mentally cry as the substance poked his face.

The smell made him miss her farts as he felt his body pushed outward to make room for his sister's shit. It was already squishing all over his face from the pressure, pushing the juicy part threw his mouth all the way down to his tongue. Which eagerly began absorbing the foul juice allowing Jeff to taste it fully. The process had only just began, but the taste was already worst than that of the pee. But instead of simply replacing one taste for a worst one, the tastes combined together creating something even worst then both taken separately. Sure enough, the taste of poop intensified as the absorption progressed which in turn amplified the combined savor.

Just when Jeff thought that the process was over and that it could not get any worst, his sister decided to sit down after getting close enough to the TV. The increases pressure pushed even more threw Jeff mouth further aggravating the taste. Only this time some semi-solid elements managed to penetrate the surface fabric as well forever staining it. Which added a 3rd taste which combined with the 2 others creating an unfathomably loathsome cocktail for Jeff "greater enjoyment".

Nina was mesmerized by the cartoon and was not paying Jeff any thought. She just laid there in her mess for a good while until her mother finally noticed a strange smell in the air. "Looks like someone needs a change" she said as she was making her way toward his sister. "Your to late" Jeff mentally cried as he felt himself lifted in the air once again. His mother brought them both to the changing table inside the nursery. "Puwaa !! you sure did a number on this one" she said as she opened the front of the diaper. Jeff was grateful to be able to see the outside world again. Even if one of his eye was covered in poop. He saw his mother prepare a fresh diaper beside Nina before she lift her but by pulling her legs up. Jeff was horrified to see his mother grab his relatively clean front and use it to srub off most of the poop that was still stuck on his sister's ass. His mother dropped her now blinded son on the table and used a baby wipe to clean the rest. Then she pulled him on the side and place the fresh diaper under her before lowering her on it. Finally, she dropped the soiled baby wipe on him before rolling him up and sealing him shut with the wipe still inside. She finished changing his sister before throwing him in the diaper pail with his new stinky brothers. "Great, now I just have to bare this taste and smell for an eternity before finally changing back" Jeff reflected.

He did not think that things could get any worst then they are already. But as time past and past. He began to notice that the taste as well as the smell were actually getting worst over time. "You've got to be kidding me ! How is this possible !" Jeff cried. Even the piss now had it's own powerful smell. Little did he know, bacterias were busy at work decomposing and rotting the foul substances even further. The process generated new types of juices dripping from the poop right down to his sorry tongue that was already so busy tasting so many things. Things were actually still getting worst even now.

Jeff's mind eventually went blank. Not able to process things any further. Until he finally felt his body change. Jeff was estatic, he have been waiting for this for way to long. The change suddenly stopped. "OMG, what now !" Jeff thought. An error message was displayed on the Chronivac's screen. "Error: Subject composition have been altered". The Chronivac had changed Jeff into a clean diaper. But when his sister used him, her wastes fused with Jeff becoming part of is inner organs significantly modifying his body composition when the gel powder chemically reacted to the various liquids. He was not just dirty, but actually different. He would have been fine as a cloth diaper as it do not involve any chemical transformation. At worst he could have been washed. But unfortunately, he had been changed into a disposable diaper. The Chronivac did not know how to deal with this and was asking for directions. But even if Jeff could have handled the Chronivac somehow, Only a skilled technician who knows his or her way around the Chronivac could get him out of this mess (literally). After a while, the Chronivac displayed more information.

"May not revert changes by inverting current transformation protocol as it could give undesired result. Would you like to attempt transformation anyways ? Or would you like to make correction to the current transformation protocol before attempting an inversion ? Otherwise, the now inanimate subject may only be transformed into an other inanimate object. The previously entered selection is selected by default. Jeff faith was now at the mercy of the Chronivac's automatic decisions.

Jeff is relieved when he feels himself transforming again. He his overjoyed to feel the overwhelming taste fade away completely as his inner self revert back from a gel like substances to a dry powder. He feels himself unroll and and lift into the air getting out of the diaper pail. "Wait, something is wrong here !" Jeff thinks while getting very worried. The comforting transforming sensation left him as he landed neatly folded on the top of the diaper stack ready to be used again. Jeff's mind could not admit what obviously just happened. He was confused wondering why the transformation was taking so much time. He had waited so long to change back and now it was finally going to happen. Surely he could wait a bit longer he thought. Especially now that the accursed taste and smell had at long last left him. Jeff never being so happy of not smelling or tasting anything. To him, the lack of taste was somehow the best taste in itself. "It's over, I wont be tasting anything like that ever again" he rejoiced while still waiting for the very slow transformation.

He waited and waited some more. it was hard to tell how long as he had absolutely no reference. But a part of him was getting worried. He was slowly losing confidence. after all, the transformation did stop before. Then he remembered that the device was still being tested. Perhaps it was buggy ? Maybe the OS crashed and it would never complete the transformation unless someone fixed it. The more Jeff thought about it the more he got worried. His mind still not wanting to admit the cruel and obvious truth. The thought that the Chronivac did exactly what it intended and that the transformation was in fact complete and successful still not crossing his mind. But it was slowly making his way there.

Time past and past some more when he eventually heard Nina (his baby sister) crying nearby. He guessed that they were in the nursery and that she was laid in her crib. His mother came into the room shortly after to check up on her daughter. "Don't cry sweety. Mommy is here for you" She said trying to comfort her daughter. "Oh my ! It's ok sweety. Mommy is going to make it all better." She said shortly after as if suddenly realizing something. Meanwhile Jeff was trying to figure out his exact location as well as what he was now. He know that he was a soiled disposable diaper and that the Chronivac was supposed to change him back. But he assumed that the Chronivac screwed up somewhere stopping midway. He was trying to figure what he was now. A towel maybe ? He felt absorbent and folded up on some desk. But that did not seem quite right. But somehow, his current location, body position and absorbent feeling all seem very familiar. Yes, almost like he's been threw all this before.

That is when he felt his sister being laid on the same desk. Then he realize that there are no desk in the nursery, but there is a changing table. A changing table full of baby supplies... Jeff was getting worried sick as his mind could not avoid the obvious truth much longer. "Let's get you nice and clean !" he heard his mother say as she grabbed him, opened him and placed him beside his sister. Jeff was completely horrified as he finally understood what his mother was doing. Now opened, he could see his mother pull aside a dripping wet diaper and then proceed to clean her bottom with a baby wipe. "OMG she is changing her ! This can't be happening ! Anything but that !" He thought hysterically as his mother gently slid him under his sister before lowering her down on him. "It did not failed to change me back ! The damn thing actually transformed me into a fresh diaper !" He thought clearly panicking as his mother was applying a generous amount of baby powder. "A freaking diaper ! Ready to be used by my damn sister ! Please God have mercy on me ! I can't go threw all this again !" He prayed hard as his mother was tapping him shut. He was worn... once again. Only this time he knew all to well how it feels to be a diaper. Jeff could not stop mentally crying as he stared at his sister's private areas fearing he see some bad signs.

Thus began the new diaper life of Jeff. Each time the 48 hours was up, the Chronivac would refresh the transformation according to previous settings (namely a disposable diaper). Jeff's family obviously realized that their son and brother was missing. But they concluded that he ran away from home. So his mother left his room (including the Chronivac and computer) untouched so that everything would be as he left it if he ever came back home. As the weeks past by, Jeff experienced all kind of state. Wet, wet and messy, Extra wet, just messy, ETC. He also experienced various types of piss and shit which were varying according to his sister diet. The variety made it hard to get used to it as it was always different. He still manage to get used to it several months later when the taste finally drove him insane. This was shortly before his sister began potty training. Part of him was hoping that someone would find the Chronivac one day. Maybe his other sister would remember that strange device that she saw her brother play with one day. Perhaps his mother would find it while dusting his old room. Maybe the company that gave him the device would eventually check back on it. Discovering everything once they do. At worst, Nina would be potty trained soon. So this would at least allow him to take his retirement from his already to long diaper career.

Or so he thought. He heard his mother speak to his dad about starting a baby daycare center. Apparently she likes taking cares of babies a lot. Going so far as baby sitting for the neighbors and with her last child growing past this now, she would be left with unused maternal instinct. Having raised 3 children, the house was already full of toys and various supplies. Beside, diapers seemed to cost less lately. Having her own baby daycare center seemed like a wonderful idea to her and Jeff's dad was encouraging her in that way. Seems like their would be no retirement...
