Joey picked up the bottle and looked at it uncertainly. The teat reminded him a lot of his pacifier but whilst the soother had become almost normalised, the bottle felt even more infantile. Lucas was happily drinking from his own, holding it with both hands and tilting it up as he eagerly sucked on the milk within.
Still lying down, using a teddy bear for a pillow, Joey raised the bottle and tipped it upside down. A single drop of juice dripped out and on to Joey’s chest before he took the plunge. He lowered the bottle towards his mouth and slipped it between his lips. He wasn’t sure he would know what to do with it, but just like the pacifier, it seemed to come naturally. As soon as the latex touched his tongue, he sucked, and a spurt of juice filled his mouth. Joey swallowed and sucked again, repeating the motion and tasting the wonderfully sweet drink.
It wasn’t long until Joey was feeling a familiar relaxation passing through him. Sucking on the bottle was giving him all the feelings of using his pacifier and yet it was, somehow, even better. Feeling the juice going down his throat as he sucked just felt… right.
When Joey looked over to Lucas, he could see his little brother was smiling at him. It wasn’t in a superior way, it wasn’t making fun of him, he just genuinely seemed to enjoy having a playmate. Joey pulled the bottle out of his mouth and smiled somewhat guiltily in return. He hadn’t been able to shake the feeling that even if he was enjoying it, he simply shouldn’t. A burp forced its way up and out of Joey before he even knew it was coming that made Lucas giggle. To cover up his blushes he started drinking again.
Halfway through the bottle, Joey felt his bladder send a signal to his brain that he would need to go to the bathroom soon. For just a second, he felt a pang of panic. Then he simply let go. Lying on his back, head propped up on a teddy bear and drinking from a bottle, Joey felt a moment of hesitation before warmth seemed to burst into his diaper. He shivered slightly at the feeling and remained frozen in place. He kept expecting to feel the urine pooling on the floor around him or running down his legs, but the diaper kept it all contained. He felt the warmth trickling over his balls and down between his legs where the padding greedily drank it up.
It was only when Joey had stopped wetting himself that the reality of the situation hit him. He pulled the bottle from his lips and looked at it with a frown of disgust, a long line of drool dripping from it. He dropped it next to him and quickly sat up. He heard the crinkles, but they were somewhat muted now. What he really felt, more than anything, was the heated padding beneath him squish and conform to his body.
Joey shivered slightly. He didn’t like how easily he’d been able to let go just then. His face was a deep red and he found himself unable to look at Joey, as if the baby could guess what he had done just by looking at him. Instead, Joey turned away and looked at the cartoons on the television screen, pretending they were the most interesting thing he had ever seen. It was surprising how quickly Joey had grown used to wetting himself. Surprising and more than a little scary.
Joey didn’t know what to do in this situation. He had wet himself. Was he supposed to call for help? Could he climb out of the playpen to find his mom? No, he knew what was expected. A baby wouldn’t do that. If a baby really needed attention they were start crying, otherwise they would just continue playing.
Fortunately for Joey, he was saved from having to think about it for too long. Fran stuck her head around the living room door not too long after and announced that dinner was ready. Joey felt as if his mom could tell what he had done just by looking at him, as if he had his shameful deed written across his forehead. He was unable to keep looking her in the eye for long.
“Come on, babies.” Fran said as she unlatched the gate and opened it.
“I’m not a baby.” Lucas said with a pout as he stood up, “I’m a big boy!”
“Of course you are.” Fran said with a big patronising smile.
Joey didn’t make any such claims as he stood up. His legs ached just a little from sitting in the pen for so long. He didn’t make any claims to being a big boy. Not when he could feel the wet diaper hanging a little from his hips, the fluffiness of the diaper somewhat reduced and replaced with a constant warmth. It wasn’t uncomfortable by any means, not like Joey would’ve assumed it would be. Instead, it felt like a sponge that had filled with warm water and was now pressing against some sensitive parts of his body.
Fran didn’t check either of them as they left the pen. Joey didn’t know if that was a good thing or not. At least it delayed the inevitable humiliation of being found wet for the third time that day. Did he normally pee this much? He couldn’t remember. Joey waddled along, trying his best to walk normally, but finding it even harder than before to keep his legs together with the padding pushing into his thighs.
At the kitchen table he found that Ben was already sitting there. He looked up briefly as Joey came in, then looked to the side and shook his head a little. When Joey followed his teenage brother’s gaze he saw Lucas’s highchair, as per usual, but next to it was another, larger one. Joey stopped suddenly. It was lucky he was the last one into the room or someone would’ve definitely walked into him.
“W-Where did you get that!?” Joey asked. He felt his anxiety rising again. It never felt like it took much to make him nervous at the best of times.
“Sandra across the road, you know she has Connor, her boy with…” Fran started.
Joey didn’t hear the rest. It was as if his vision was so overwhelmed with what he was seeing that it overrode all his other senses. He knew what his mom was going to say anyway. The family across the road had a son with special needs and, apparently, they no longer needed this chair. It wasn’t exactly like a highchair, but it was close enough to make no difference to Joey.
“So, let’s try it out.” Fran said with more excitement than Joey thought the situation deserved.
“Are you sure…?” Joey asked slowly.
“Of course.” Fran replied as she placed a hand on Joey’s lower back and guided him towards the chair, “It’s not like I got it for Ben!”
“Hell no.” Ben muttered as he folded his arms across his chest.
Joey gulped and stepped forwards. The seat was raised just a little, but it was enough that when he was sat down on the padded seat, his feet swung in the air. His head was level with Lucas who was being sat in the regular highchair. A tray came down in front of Joey, locking him in place as he squirmed to get comfortable on the unusually high seat. As Fran went over to the counters to get dinner, a thought occurred to Joey.
“Wait, what did you tell Sandra?” Joey asked with wide fearful eyes, “Who did you say the chair was for?”
“Don’t worry, baby, I was vague.” Fran said. She rolled her eyes as if she couldn’t see the big deal, “I just said I knew somebody who could make use of it.”
Joey felt a little relieved. He felt particularly exposed in the highchair next to Lucas though. His mom had sat down in the chair on the other side of him whilst Ben sat next to Lucas’s highchair. A plate of food was placed in front of him; it was basically the same as what his mom was having except that the meat had been pre-cut. There was no cutlery and Joey knew that could only mean one thing. One of his duties over recent times had been to help feed Lucas, now he was the one in the highchair. What little appetite he had vanished.
“Ben, can you help Lucas with his dinner?” Fran asked politely.
It looked, for a second, like Ben was going to complain. He was already chewing on his first mouthful of food as he opened his mouth to say something. Then he looked at the two people in the highchair, particularly Joey, and he closed his mouth to swallow. A smile appeared across his face.
“Sure thing, mom.” Ben said cheerfully as he scooted his chair closer to the baby of the family.
Well, one of the two babies of the family, Joey realised with a sinking feeling. After all, he was pretty sure Lucas’s diaper was still dry, he was the one who was sitting in his own urine. The reminder made him shudder.
“I can feed myself…” Joey whined. He lowered his voice as he finished, “Mommy.”
Joey clearly didn’t speak quietly enough as Ben snorted with laughter. He was leaning over the tray and scooping some of Lucas’s food up with a spoon. Joey tried to ignore the way his cheeks were blushing. He tried to act with as much dignity as his position allowed him. It wasn’t much.
“You don’t need to worry about things like that.” Fran replied cheerfully, “Just let us take care of you.”
Joey wanted to complain more but his mom was already using a spoon to scoop up a bunch of his meal. It did look very nice, but Joey didn’t want to eat it. He wasn’t even sure if he could swallow with the shame coursing through him.
“Open up for the choo-choo train!” Fran said cheerfully as she raised the spoon of steaming food.
Joey felt almost as embarrassed as when he had wet himself in front of her. He slowly forced his mouth to open as his mom made train noises and brought the spoon closer to his mouth. On the other side of him, Joey could hear Ben doing the same thing and Lucas responding with giggles.
The spoon went into Joey’s mouth, and he swallowed what he was given. It did taste very nice which helped lessen the blow of what was happening a little bit. Joey’s preference would’ve been to eat his meal as fast as possible so he could get out of the highchair and end the embarrassment. However, he had to wait for his mom to feed him, which meant she controlled the pace, and she was clearly in no hurry as she talked to Ben about his day. Joey remembered when it used to be him who she talked to like that.
“Oh, Ben, could you get the babies their drinks?” Fran asked as she pointed to the fridge behind her, “I forgot.”
“No problem.” Ben replied. His eyes darted to Joey before he pushed his chair back and stood up.
Joey was unsurprised that the drink was in a large baby bottle. It was placed on the tray in front of him and the cap was lifted off. He saw the latex tip and was reminded of his soother again. He needed soothing, so he picked it up and pushed it between his lips with minimal hesitation. He tried not to focus on his peripheral vision where he could see his mom smiling cheerfully and his teenage brother equally happy but for different reasons. The juice was nice though; he tried to focus on that taste instead.
Dinner felt interminable. Between every mouthful of his own food, he had to wait for his mom to eat, and she seemed to have no end of gossip to share with Ben who was only too happy to keep the conversation going and prolong their time at the table. Halfway through the meal, he had drained his bottle, and all the extra liquid was putting pressure on his bladder again.
Joey froze up as he relaxed his muscles in the same way he had already done several times that day already. Had it been twice? Three times? It didn’t seem like a good thing that he couldn’t remember just how many times he had wet himself. He knew what wetting himself felt like, but when he felt a stream of warmth trickling into his padding, he wasn’t able to repress a little shudder. He hoped no one could tell what was happening as he opened and closed his mouth like an automaton, eating his dinner whilst focusing on the warmth spreading around his crotch and tickling his skin.
Eventually his wetting came to a stop, and he released a breath he hadn’t even realised he’d been holding. He moved slightly in his seat, trying to assess if the diaper had managed to hold everything. He was a little surprised that it had. It was more absorbent than he would’ve given it credit for.
Fortunately, no one tried to talk to Joey for most of dinner, in the same way that no one talked to Lucas. The only time he was really engaged with was when his mom repeated the “choo-choo train” motions as she lifted a spoon towards his mouth.
By the time dinner was done, Joey was more than ready to get away from the embarrassing scene and find a place to hide. As soon as the tray in front of him was unlocked and lifted up, he slipped off the seat and against the edge of the table. Before he could take a single step, he felt a hand reaching between his legs causing him to jump. He was sure he would never get used to people doing that whenever they wanted.
“Good grief, you’re soaked!” Fran said with a cluck of her tongue, “We need to get you changed pronto.”
Joey wasn’t going to argue with that. As Fran took his hand and led him away from the highchairs, he found walking to be much more difficult. The diapers truly could swell up to be much thicker than he could’ve possibly imagined. He looked over his shoulder where he saw Lucas being checked by Ben, when his teenage brother looked up, he smiled widely and pulled up his phone. A photo was taken before Joey could reach the stairs. He shivered as he thought about all the places it might end up.
Joey was taken to the nursery and told to get up on the changing table. Something that was easier said than done, the thick diaper making everything more awkward. It took his mother’s hand on his squishy rear end to get him up on to the padded surface for yet another diaper change.
“I didn’t think you’d go through these so quickly.” Fran said as she pulled the poppers of the onesie apart, “Maybe I need to look for some thicker ones.”
“There are… thicker ones?” Joey asked hesitantly.
“Oh, yes.” Fran chuckled, “A lot of them list their absorbency and you wouldn’t believe the numbers I was seeing. If they made them in Lucas’s size, I’d never have to change him!”
Joey must’ve made a noise, perhaps a pathetic little whimper, because his mom was soon leaning over with a pacifier. He popped it into his mouth and sucked. It was strange how such a small item had kickstarted the whole mess he was in.
His warm diaper was removed, and he was wiped clean. He sucked on the pacifier for more relief as he was left so completely exposed to his own mother. A fresh disposable was placed underneath him and then the onesie was done back up. Yet again, his brief foray with being unpadded had been all too brief.
Joey was led to his crib, and he surprised himself by not complaining as he went inside. He was more than ready for some time alone and, he had to admit, despite his nap earlier in the day, he was still feeling pretty tired. He laid down and pulled a blanket over him just as the door opened and Ben brought Lucas inside.
Lucas came running in, stopping at the edge of the inflatable bars and pushing his grinning face against them, drool leaked out on to the plastic. He pointed inside and Joey felt like pulling his covers up and over his head to hide himself.
“Baby!” Lucas said. He then laughed wildly as he ran around to the changing table.
“Come on.” Fran said as she lifted the youngest brother on to the table for his own fresh diaper, “Make sure you stay in your crib, by the way. I don’t want a little explorer wandering the landing and hurting himself.”
Joey, his cheeks red, laid down and pulled the cover up and over him. He didn’t need his mom to tell him to stay inside his crib. He faced away from the changing table so his mother and baby brother couldn’t see how much he was blushing. As always, when he closed his eyes and tried to focus on things other than his immediate present, his mind automatically went to what his friends would think about all this. He sucked on the pacifier for comfort as he imagined Tracy standing over him and laughing.
There was no way Joey could let his girlfriend know what was happening. It would be the end of their relationship, for sure. How could she ever take him seriously after this? She would already be mad at him for being out of communication for the weekend. He hadn’t even seen his phone since everything had started. What was he going to say to her? That he was grounded? It would be embarrassing for an eighteen-year-old to say that, but it was certainly better than the truth.
Lucas’s change was over in fairly short order. He was taken to his crib and Joey rolled over as his mom and baby brother passed so he was still looking away from him. He sucked on his soother as Lucas was placed inside the crib. Fran then drew up a chair and started reading a story for the baby. Joey listened as he closed his eyes. At first, he wished his mom would just leave so he could get to sleep, but it wasn’t long until her voice became soothing for him. He found himself sinking into unconsciousness with his mother’s voice in his ears and his pacifier in his mouth.
---
The next thing Joey knew, he was opening his eyes as the first very early rays of sunlight were coming through the window. Joey was on his back and, to his surprise, still had his pacifier in. His first instinct was to go back to sleep, that it was much too early to be waking up. He closed his eyes but after just a few seconds they opened wide.
There was a very good reason that he had woken up so early and it wasn’t all down to his early bedtime. There was a gurgling in his stomach that, try as he might, he couldn’t ignore. It was a feeling of uncomfortable fullness that made him want to curl into a ball. He needed to poop.
Joey noticed there was already the smell of a dirty diaper wafting through the room. For a second, he thought it was coming from himself, and he felt a chill running over him as he considered that he might have lost control in his sleep. A second of patting his backside revealed that he seemed to be clean and dry. He let out a deep breath. The smell was coming from Lucas.
The relief was short-lived as Joey knew that unless something happened quickly, he was going to end up in the same situation. He could only imagine the smell of two poopy diapers in the room at the same time. He swallowed anxiously. This feeling of fullness in his lower gut wasn’t going anywhere. It was as if he could feel the muscles of his digestive system individually pushing his waste closer to the exit where it was hitting a jam.
Joey’s foot tapped quickly against the inflatable surface beneath him. He bit the inside of his cheek and tried not to focus on the increasingly unpleasant feelings. He wanted to distract himself but there was nothing to concentrate on except for a couple of teddy bears in the crib with him. Mortimer, the stuffie from his childhood, had somehow ended up in his arms whilst he slept and he pushed it away. He could climb out but… then what? He wasn’t allowed to use the toilet. Would he be punished by his mom? Would she spank him?
Questions chased each other around Joey’s head and none of them had easy answers. The whole time he remained in his inflatable baby bed, doing nothing but worrying, he came closer to disaster. He clenched harder and harder, but it seemed to only make the need to poop all the stronger. He felt increasingly panicked. He hadn’t done this in his memory; to do it then would be the most humiliating moment in his life. The diaper crinkled as his leg kept twitching. It was almost inviting him to let go. He had never known feelings like it. Not just the physical sensation of needing to poop, but the panic that was flooding his system as well.
“Oh god…” Joey muttered to himself as his tummy cramped up again.
Joey was laying on his back, staring up at the ceiling through shimmering eyes. It would’ve been so easy to just let go, push down and end the pain in his intestines. The twisting and cramping feelings were making it almost impossible for him to remain still and a tear leaked out of the corner of his eye.
Before Joey was mentally prepared to give up, his body made the choice for him. A cramp, longer and stronger, than the ones that came before it, wracked Joey’s digestive system. When it reached its apex, and he was debating if he could make it through, his muscles took over and started to relax slightly. The cramping remained the same but the pressure on his exit grew inexorably until finally…
Joey froze. His eyes and mouth were wide open as he lost control directly into his diaper. With all the pressure that had been built up it felt like one second the padding was perfectly clean and the next it was incredibly dirty. A sticky feeling seemed to explode across the back of the padding as Joey’s muscles pushed down, eager to get everything out of his body.
Joey grunted softly. He bent his legs in the air a little as he felt the diaper change shape to accommodate his mess. His face was going a bright red and he couldn’t help thinking, even in that moment, how this was surely not what his mom wanted him to be doing. When she saw him like this wouldn’t she be disgusted? Wouldn’t she see her adult son as being truly pathetic? He couldn’t handle a few chores and now look what he had been reduced to. She’d never told him he had to poop himself, did she? Maybe she expected him to use his common sense and go to the toilet to do… that.
Another push. Another large lump pushing out the diaper and spreading its muck. Joey could feel it all over the back half of the padding, all the way up to the back of his intimate parts. He prayed it wouldn’t go any further, the situation was already disgusting enough.
Joey pushed down again. This time it was his choice. It wasn’t like he was going to get any messier and it was better to get it all out as soon as possible than prolong this humiliation. He shivered as the last of the waste of his bowels emptied into his underwear. He heard a muffled sound of breaking wind and shuddered.
To complete the humiliation, Joey’s bladder gave way a second after he finished pooping. He slowly relaxed as he felt the warmth of his bladder releasing, washing down over him. He lowered his legs against the inflatable beneath him and closed his eyes. He couldn’t stop the tears running out the sides of his eyes.
“What the hell is happening…” Joey muttered to himself as he rubbed his eyes with his hands.
Joey tried not to move at all. He could feel what he had done touching his skin and he felt a deep need to get it away from him. The smell in the room had definitely got worse, he was sure that wasn’t just his imagination. The already pungent air from Lucas’s usage of his diaper had been added to.
Joey was still wondering what he should do when, like so many other things recently, the decision was made for him. He didn’t want to move, remaining flat on his back and looking up, he just tried not to freak out about what he had done. It threatened to overwhelm him; a pure panic that made him want to do something even if he wasn’t sure what that was.
The bedroom door slowly opened, and Joey immediately hid his face in shame. He heard the footsteps come into the room and sniff the air in an exaggerated manner. He was completely frozen, surely only moments away from having his disgusting state discovered by his mom.
“My, my… It certainly seems we’re overdue for a change.” Fran said as she lowered the side of Lucas’s crib.
