Spending time in the future was usually fun and a break from the stress that the feudal era gave out but the bucketful. Usually but not this visit. Inuyasha should of known something was up when Kagome A) kept talking about how upset and babyish Souta felt needing bedtime diapers as of late (and some day time pull ups, there had been little leaks) but also B) was giving Inuyasha all the instant ramen noodles he could handle and more. 
Sadly, nothing quite clicked till they had arrived and then he'd been cornered not only by Kagome, but her mother as well while Souta was playing out behind the house.. and from there everything had gone downhill.
After a long talk (Well the women had talked, Inuyasha had argued but they seemed to ignore any points he made) Inuyasha found himself making a deal that he would give Souta the confidence boost he needed by having someone bigger then him be more BABYISH then him.. and in return Inuyasha got whatever he wanted, whenever he wanted it next time he visited. 
"And let me tell you right here and now, My list of demands are gonna be HUGE!" Inuyasha growled. 
Kagome however just smiled and patted his head like he was already just a huffy baby and had lead him off to get dressed for the part.

Souta huffed as he kicked the soccer ball at the goal post, catching it and kicking it back over and over. It just wasn't fair that his bladder was betraying him like this when he was -9- years old! without a doubt in his mind, he was the biggest diaper baby in the whole town, heck maybe even the whole freaking country!  
That thought was interrupted as he heard a LOUD crinkling noise and turned to see what it was.. and his ball hit his shin as his jaw almost hit the ground. 
Waddling out behind behind Kagome dressed in a red onesie that did NOTHING to hide the thick, massive diaper(s) he was wearing and a pair of sandal's was Inuyasha!
The Half demon was beet red and seemed to be tugging on Kagome's arm, making it clear he'd rather go back inside even as he looked this way and that until, heh, she stopped and gave him a swat on his padded backside and shook a finger at him, talking clearly.
"No Inuyasha, you've been hiding inside for 2 weeks now, you need some fresh air and that's why we're in the future." She scolded. 
"But..but.." Inuyasha whined. 
"It's ok Inuyasha, I'm sure Souta won't tease you just because you can't control yourself right now." Kagome said in a motherly tone, then turned back to Souta. "Isn't that right Little guy?" 
"heh..hehehehe yeah no, I won't at all Little yasha!" Souta said, a big silly grin breaking out on his face now."What even happened though?" he asked, coming over to the pair. 
Kagome let go of Inuyasha's hand though gave him a look and the huffing diapered half demon plopped his butt onto the soft dirt of the back yard. 
"Oh, we got attacked by a crazy priest who figured the only way to redeem demons was to teach them humility." Kagome started, a well practiced lie. "Basically Poor little Inuyasha, heh, or yasha as you called him..I like that! Anyways, he lost a lot of power and well control of his tinkles and uh-oh's for 3 weeks.Not to mention he's become a lot more..childish as you might of noticed." As Kagome said that with her back to the half demon Inuyasha stuck his tongue out at her and Souta covered his mouth to keep from giggling. Kagome turned to see what was so funny but Inuyasha had stopped JUST in time and was looking away, trying and failing to whistle. "...Anyways..I've been trying to deal with it in the past but frankly he's been stinking up his cabin and I'm sick of washing his diapers. figured why not let him spend the last week of it here and enjoy the freedom to play outside AND the wonders of disposable diapers." she finished. 
"oh well, shucks , Little yasha could of came here sooner! I would of helped look after him!" Souta said, swelling with big boy pride since heck he was just in a nice and slim pull-up AND he didn't stink up his diapers! "If you wanna take a little break I'll even watch him for you right now." Souta added. 
"Will you? that'd be great!" Kagome gushed and ruffled his hair. "Oh, one thing, with Inuyasha starting to get his control back, you'll have to keep asking him every so often if he need to potty or needs a diaper change. about once a hour. I'd worry more on the diaper change though myself." 
the fact that Souta was suppose to be doing a potty check himself once a hour flew right over his head and the little 9 year old nodded and gave a thumbs up. 
"Don't worry sis, I got this!"

Inuyasha was mentally adding heaps on his list of demands as his new nick name caught on and Kagome went out of her way to make him seem even more helpless.
with his 'darling' girlfriend retreating inside, Souta came over to him and smiled, then bent down and sniffed, confusing Inuyasha for a second.
"Hmm, you SMELL clean for the moment at least." Souta said and then patted Inuyasha's head. "Good boy!"
If he made it thought the week without having to kill someone Inuyasha wanted all the good damn treats.. but knowing the role he was SUPPOSE to play he gave a silly grin (And the heat pats kinda sorta maybe felt nice too.)
"Well little yasha, what do you wanna do? I was playing some soccer but if your muscle control and stuff is all messed up I don't think that's a good idea. sides you likely can't move too fast in your diapies." Souta said.
'So nice but still being a jerk..it must run in the fucking family.' Inuyasha thought then put a thoughtful look on his face. "Ummm we could play hide n seek!" Inuyasha offered up, putting a doopy childish twinge to his voice. 
"ok, You hide and I'll seek. I'll give you to the count of 20." Souta said and went to cover his eyes when Inuyasha tugged at his shorts. "Hmm? what's wrong?"
"How many is 20?" Inuyasha asked, rubbing the back of his head sheepishly, not having to force a blush as the pure humiliation of this all was taking care of it for him.
A big grin broke out on Souta's face and he bent down and took Inuyasha's hands in his. 
"20 is this many.. and then" and Souta let go of Inuyasha's hands and tapped a finger on the exposed toes since Inuyasha had gone sockless in the sandals. "and this many. Can you keep track of that?" 
"Ummm I think so!" Inuyasha said and nodded his head, having to admit that was all sorts of cute.
"Ok then, when I hit 20 you'll hear me say, ready or not, here I come anyways in case you lose count." Souta said and with a last head pat, he stood up and closed his eyes, starting to count. 
Of course Inuyasha could of scaled a tree or taken to the roof top even with the bulky diapers he had on, he decided to play fair and also, knew it would ruin the whole plan and he hadn't of put up with it THIS far just to fuck it up now. 
He needed what would seem like a good hiding spot to a toddler but clearly wouldn't work for him and now up on his feet he scanned the yard. 
"One...two...three...four.."
Jesus, this wasn't like a life or death battle but for Inuyasha he found himself frozen on the spot, trying to figure out what would work, his natural instinct to win was messing up his need to lose!
"Five...six..seven.."
ok this was just getting stupid! he fought the urge to face palm and then spotted a narrow opening under the steps to the back porch, it would hide him from Souta's direct line of sight but would of gotten him caught as soon as the little guy came close.
"Eight...nine...ten, That's half the count yasha!" Souta called.
'heh, he really is a fair sport.' Inuyasha thought, then as stealthy as he could (read, not at all) waddled his way over to his chosen hiding spot even as his tummy started to feel a little bit weird. 
'Must be that glass of icky juice they insisted I drink before coming out so I don't get dehydrated.' Inuyasha thought, crinkling loudly and having to speed up.
"Fourteen...fifteen...sixteen..." Souta called out, a big goofy grin on his face.
Waddling with all the speed he muster and keep up the lie, Inuyasha drove to get into the hole.. and found out that while he had been right he could of squeezed in there normally.. he hadn't taken into account the triple diapers. His upper half was in, but his padd butt and legs stuck out and he knew if he tried to force himself in,he'd end up losing them. 
'fuck my life..'
"seventeen, eighteen..nineteen...twenty! Ready or not here I ..pffft.. come..heh. Did you get stuck little yasha?"
Inuyasha had been about to push himself back out but with Souta's suggestion, figured that worked and started to give out a sheepish yes, but his tummy cramped and it came out much more panicked. 
"Yeah! Uh.. Please help me git out!" he said, one hand keeping him from going into the dead leaves and the like under the step but the other was on his tummy, and he kicked his legs a little more to try and work out the cramp.
"hey, it's ok! don't worry! I'm coming over, though you have to stop kicking your legs. I'm gonna grab you at the waist and pull you back, so watch your head!" Souta called, and Inuyasha could hear him running over. 
"O-Ok." The half demon whimpered, the cramps were getting worst and he semi pushed back a little giving Souta a better place to grip though he didn't take into account with the building cramps he might not want someone wrenching on his midsection. 
'oh god, this feels like that time I ate those clam's that had gone bad right before I..I..Oh those fucking bitches!' Inuyasha thought, cluing in to why the ladies of the house had grinned so big when Inuyasha had downed his drink to get the icky tasting thing over and done with. 
he had a brief second to think about just calling this off, he'd get himself out and whine to Souta that his tummy hurt and try and shit himself somewhere private, but by then it was far, far too late. 
Souta's little arms and hands were trying to pull him out and the extra force on his tummy tum meant that while he did get free, pushing himself back to make it look like it was all Souta, he banged his head on the step knocking him loopy for a split second and also started to filled his diapers. 
As he loudly farted and giggled, he wore a blissful stupid derp face.

Souta was shocked at just how strong he was as he freed the poor trapped little guy, though it was soon replaced with amusement and disgust as Inuyasha started to let out massive wet fart and then more then that, a stupid look on his face.
"Uhhh yasha, are you going boom boom?" Souta asked, holding his nose. it was rhetorical question at this point as the diaper was starting to swell, so Souta didn't figure he was gonna need to do a sniff check. 
"Hehehe Ya! Going PBBBBBBTTTT!" Inuyasha giggled and stuck his tongue out, blowing a raspberry.
"heh, you surrrre are buddy. but it's ok. You uh.. stay here and finish up and I'll go get Kagome ok?"  He said/asked, coming over and patting Inuyasha's head. 
"OOOOOOTAYYYY!" the diaper pooping derp coo'ed. 
"heh..wish Kagome would of worked me you went all derp when you unload. kinda cute." Souta giggled, then dashed up the step's to stick his head in the back door. 
"Kagome! You need to come and get your boyfriend, he's pooping himself silly, Literally!" Souta called. 
Yeah, wearing pull-ups sucked, but as Souta pulled his head back out of the back door and looked down at Inuyasha, at least he was a stinky diaper derp. 

The end..for now
