(Well...here I go...)
Kyle shut his eyes, took a deep breath, squatted down, and began to push. His cheeks were red hot, both from the strain and the realization of what he was doing, as gassy sounds escaped him. He tooted and hissed in varying pitches and lengths, and so far that was the only thing coming out. Sweat began to bead on his forehead from the effort of emptying himself, and he wrapped his hands around his kneecaps to get a grip on himself. As it went on, his breathing quickened, as did his farting; he even heard a light piddling sound as well.
Then came the actual mess. He continued to grunt, groan, and produce nasty noises from down under as his ever-filling diaper began to droop. The whole experience was rather humiliating, and he felt more and more disgusted with himself with every flatulent sound that reached his ears as a result of his infantile act. He could feel the waste sliding out of him, hear the sickening splatter as it landed in his padding, and he wished it would just end. But there was no stopping it once it began, and since he was already this far into the process, he figured he might as well go all the way.
"Nnnngh...aaaaahhhh..."
Kyle sighed again as the messing ended and the cramps faded, feeling the familiar relief that came afterward, despite the embarrassing situation. He stood back up, and felt his diaper sag from the weight of his output; it was down to about the middle of his thighs. Looking down, he could see that it was lumpy and bulgy at the bottom, which only made him cringe and feel sick.
"Ughk..." (I can't believe I just shit myself...)
His face lit up from the shame, and he didn't want to move. He soon heard Corrine approach him, and he turned to face her.
"Phew! Someone's due for a change!" she teased, waving a hand in front of her nose.
"S...Sorry, Corri--er, Mommy..." Kyle could not bear to look at her.
"Well, you gotta go sooner or later...c'mere..."
Corrine offered him her hand, and he took it as he followed her back to his room; he felt his full diaper slightly sway about as a result of his walking.
"Um...did you...spike my food or something?" Kyle asked.
"I put some laxative in your milk. I wanted to make sure you weren't constipated!"
"Couldn't you at least given me one that didn't make my stomach hurt?"
"This one works faster! And the pain is only temporary; it hits ya, but then you feel better!"
"Mmmmm..." (I...guess she has a point...)
"Here we are! Lay down..."
Kyle got onto the changing table in his room and lay down as Corrine gathered the changing supplies. There was something quite relaxing about just lying on a table and awaiting a diaper change. What he could have done without, however, was the sudden uncontrollable burst of air.
"Uh oh! Does Kyle still need to go?" Corrine spoke.
"N...No...just gas..." He blushed once again, holding onto his stomach.
"Good. Otherwise you'll have to keep that diaper on 'til you're done!" She chuckled.
"Really? You're gonna let me get a rash?"
"Diapers aren't cheap, y'know! That's why I want you to use yours to the fullest before I change you!"
"Alright alright!" Kyle glared at her, crossing his arms.
Corrine undid his dirty diaper and cleaned him up; he had a chill throughout his body when he felt the cool wipes on his rear, and he slightly shuddered.
(Brrr...too cold...but...kinda nice, too...)
He then felt the baby powder his "mommy" dashed onto him, which was also surprisingly pleasant.
"And...done!" Corrine spoke as she finished fastening a fresh diaper onto Kyle. "All clean and ready to go again!"
He saw her dispose of the used diaper in the nearby pail as he sat up, leaning on his hands. Kyle's face was red once more, and he had an uncertain, wavering smile.
"Th...Thanks, Mom. I feel much better already."
"Think nothing of it!" Corrine hand-waved with a content smile. "Mommy's always here to clean up your messes!"
"Heh heh...I'll...try not to get too messy, then..." Kyle replied as he got off the table.
"No, by all means, be as messy as you want! That's what babies do best, after all!"
Corrine gave her "son" a big hug, and the tingly, warm sensation came back. Kyle blushed, reluctantly returning the embrace.
"I love you, Kyle...my wonderful little boy..." she quietly, soothingly spoke.
"I...I-I-I...llll...llllove you too, Mommy..."
Kyle gulped, feeling tears well up in his eyes. He did not know why he was feeling so sentimental in this moment, given all that he had been through so far, but he thoroughly enjoyed the hug the two of them shared.
(Why...why do I want this to last forever...?)
"Okay!" Corrine spoke, still smiling as she exited the hug. "I'll let you get back to your playtime! Have fun sweetie, and call me if you need changing again!"
She pecked her "son" on the forehead and playfully tapped the tip of his nose, and once again he felt tingles.
"W-Will do!" Kyle nodded, smiling as well.
He happily sighed as Corrine left the room, and he pondered what to do next.
(I have to get out of here sooner or later, but...I can't say I'm not having a good time either...I can play just a little longer before I make my escape...)
"Hmm?" Kyle's gaze landed on the baby walker nearby. It was white with a light blue seat, which was decorated with various underwater-themed items like seaweed, fish, and bubbles.
(This looks...fun, I guess...let's take you for a spin!)
He sat himself in the walker, and again, felt a weird sort of pleasure as his fresh, powdery diaper pressed up against him. He got a look the various doodads in front of him: 3 cylinders on his right, partially embedded within the walker's "table", that depicted numbers, letters, and shapes. Right from that was a relief which looked like it could hold one of those oversized baby bottles he drank out of earlier. To his left were two orbs attached to a thin rail, which was connected to the "table" of the walker. Finally, right in front of him rested a red button that was practically begging to be pushed.
"No, too obvious..." Kyle muttered to himself, opting to instead spin the cylinders.
"Heh heh...ha ha ha!"
Once again, he was having a good time doing something that someone his age was not supposed to have fun with. The whirring sounds the cylinders made as he spun them faster and faster was oddly appealing; Kyle even did it with two hands, just to see the depicted symbols blur together from the sheer speed of the rapid rotation. He smiled open-mouthed from this activity, not unlike an actual baby. Next to be tested were the orbs attached to the rail, and they made a rattling sound as they were moved from one end to the other, and back again. This didn't amuse Kyle as much as the cylinders, but he too enjoyed this. And then, all that was left was...
(Let's see what this button does...)
With both hands, Kyle pressed the inviting button; he was greeted with the recorded sounds of a roaring lion, which slightly startled him.
"Hmm..." He had an idea, and decided to experiment. He altered the cylinders to display different symbols than the ones they had been set to. Kyle's hypothesis seemed to pay off: By setting the cylinders to "2", "D", and the square symbol, and then pressing the red button, the sound changed to a dog barking.
"Whoa...!" He was impressed that it had actually worked, and he had an itch to try out other combinations. But first...
(Let's test these wheels out!)
Kyle grasped the edges of the walker and used his feet to roll out of the room and into the hallway. Thankfully, there was a decent amount of room for the walker to go on through to the playroom, where the real fun was about to be had. Despite the various objects on the floor, there was still plenty of free space for what he was about to do.
"Whooooo!"
Kyle ran as fast as his feet could around the playroom, feeling exhilaration from the speed and effort. His heart raced as he did, a great big smile on his face the entire time. Maybe this would get him into trouble, but he didn't care; it was far too much fun. The risk of stepping onto a stray toy or losing control of his walker was also of little concern to him. All that mattered right then, in that moment, was the thrill.
"Kyle Hayner!"
He skidded to a halt when he heard Corrine's demanding voice over the intercom, and a different kind of chill ran through him.
"You're going to hurt yourself! Slow down!"
"S-Sorry, Corrine...er, Mom..."
"Get out of the walker, please!"
"Aww..."
Kyle sighed in disappointment as he stood up and stepped out of it; Corrine briskly walked over to him.
"If you can't stop this reckless behavior, I'm just going to take it away!"
"You're punishing me?" he complained as Corrine moved the walker away.
"I don't want my baby boy getting hurt!"
"Aaaagh...!" Kyle crossed his arms, frowning in a way reminiscent of a pout.
"Play something else, sweetheart," Corrine spoke as she returned, no longer cross.
"Fine...um, by the way, how do you do that...thing?"
"What thing?"
"The...overhead speaker thing," Kyle explained, motioning his arms above his head.
"Oh, that!" Corrine pulled a small electronic device from a holster located on her right hip. "This device lets me see what's going on in the house, and I can speak from it too! Wanna give it a shot?"
"Um, sure..."
He was handed the device, and upon inspection, he saw a color screen that depicted one of the camera's feeds, which showed both him and Corrine in the playroom. Looking around, he quickly found the camera on the ceiling. Going back to the device, he saw several buttons, which included two buttons with opposing arrows on opposite sides of the screen, one button on the middle-right that had an image of a person speaking (with visible speech lines), and a blue button below that which depicted a lightning bolt.
"This one, sweetie," Corrine said, pointing to the button with the person speaking.
"Okay..." Kyle held it down, and spoke into the device: "Hellooooooo?"
He heard his voice on the intercom almost immediately after speaking, which made him jolt in place.
"It's pretty cool, huh?" Corrine spoke, smiling.
"Yeah..." He smiled, but it quickly faded as the device was taken from his hand and placed back in the holster.
"Okay, you've had your fun. Now it's bonding time!"
"What's that?"
"You'll see! Come..."
Corrine took Kyle's hand and led him elsewhere. Whatever this "bonding time" entailed, he wasn't quite looking forward to it. But, given his surprising enjoyment of everything else, he might just end up liking it as well.
