When your going to school, is there any better time of the year then summer vacation? Hell no, even if your school is far more awesome then most since your in training to be a superhero.
And getting to spend your vacation with the love of your life, in a beach side cottage not far from a little town? Even better!
However there could also be one tiny little problem with getting to share a bed with the love of your life for three months, If the prideful blond hair hot head failed to mention that he's a life long bed wetter.
This was the sad fact facing Shoto as he woke up for the fifth morning in a row soaked by his boyfriends urine.
The more powerful (in terms of raw power as well as muscles) teen scowled at Katsuki as the blond was still blissfully unaware of what he had done, snoring softly and sucking on his thumb.
Grabbing his pillow Shoto was tempted, sorely tempted to whack the blond in the face with it, but instead held his breath and counted back from 10 before replacing it.
"Wake up doofus. you soaked the bed. again." Shoto said, trying to keep the edge out of his voice.
Katsuki snorted and slowly opened his eyes.
"hmm what? Nggh.." and turned over, tugging his pillow over his head. "Five more minutes mommy." he said in a sleepy voice.
Shoto smirked at that, but reached over and grabbed the pillow.
"I'm not your mommy, and you need to get up. We're taking care of this today bed wetter." he said, though he couldn't keep the amusement out of his voice.
Katsuki grumble and then opened his eyes, sitting up in bed and yawning, then froze.
"I..I Uh.." he stammered, quickly realizing that he was in the pee soaked bed.
"You wet the bed. I know. come up, Outta bed, I need to get the mattress out to dry. Again." Shoto said.
"M-Maybe it wasn't me! you ever think maybe YOUR the one pissing the bed like a fucking toddler?" Katsuki huffed, blushing but scooting out of the bed all the same.
"Really? I'm not even gonna dignify that with a answer. go get in the shower." Shoto said, rolling his eyes.
"..Yeah ok." Katsuki said and scurried off.
Shoto sighed and got out of bed, the poor mattress had been new but already was doomed to be pee stained for the rest of it's life. 
Stripping the blankets and sheets off of the soaked bed, he walked to the washing machine by the bathroom, glad to hear Katsuki was showering and stuffed the soiled bedding as well as his own soaked shorts in the machine, then noticed that Katsuki had 'thoughtfully' left his pissy PJ bottoms out for him.
'..At least he's not trying to hide them till they stink the place up.' Shoto thought and added them to the wash and started up the load, before moving in to join his boyfriend in the shower.

After a nice hot shower, with some nice hot love making, Both boys were dressed and clean, and sitting down to enjoy a breakfast. 
Shoto was having toast and egg, while Katsuki was finishing off his box of Cap'n Crunch. 
"we're gonna need to go into town today." Katsuki said between mouthful's, milk dribbling down his chin but at least he was leaning over the bowl so his light green muscle shirt was getting milk stained. 
Shoto meanwhile was in a loose white t-shirt and both boys were rocking tan shorts and black sandals.
"I was going into town anyways. and you're coming with me." Shoto said, carefully finishing ff the last of his food.
"oh, what we getting? we're good for food otherwise..heh." Katsuki got a impish look on his face. "Unless you wanted ta check out that sex shop i pointed out last time you horn do-"
"Oh for the love of..No. we're getting you bed time diapers." Shoto cut Katsuki off.
the blond choked on his last spoon full of cereal and when he could speak glared at Shoto. 
"No.Fucking.Way!" he growled. 
"This isn't up for debate. You can either come with me willing, and have a say on what brand of diapers I get you, or you can go over my lap and get a spanking and be put on time out till I get back." Shoto said, and finished the last of his coffee, silently daring Katsuki to try and call his bluff.
The fact of the matter was, Shoto had learned quickly that the only way to calm the brat down when he got going, was a good old fashion trip over a knee. (well actually, it had been Katsuki's mother who had let him in on it)
"..Your a butt you know that? a total, farty BUTT!" was all the blond said.
"mmmhmm. Do the dishes up while I put the mattress out on the railing to dry." Shoto said and got up and started to leave the room. "and flip me off again and I'ma wash your mouth out. " he added, not even turning around.
"...How does he fucking do that?" Katsuki muttered, quickly lowering his hand, and getting the dishes gathered up from the table.

with each boys chore down, they headed into town, walking since it was just a five minute walk. or at least it normally was. 
Katsuki had decided to stage a silent protest of sorts by going as slow as he could, and it took them a full fifteen minutes to get to the all-mart.
"Keep pressing your luck and I'll get a stroller for the walk back." Shoto warned the brat.
"You don't have the BALLS to tr-" Katsuki started, and quickly faltered, looking down at the ground. "Y-Yeah ok."
Shoto wished that he hadn't of made the threat as Katsuki was even more sulky now. Hoping maybe the bed wetter's attuide would improve with a little bit of a delay in getting his bed wetting pants, Shoto steered the cart to the grocery side of the store first. 
"...I wanna get more then just Cap'n Crunch." Katsuki spoke up as they came up to the cereal aisle.
"Oh? 
"I want candy. LOTS of it."
Shoto smirked, it was more or less sounding like the bed wetter had offered up a price of sorts if he was gonna have to get the bed wetting pants. 
"I think we can swing that. though you're not eating it all at once. last thing I want is you bouncing off the walls."
"Oh come on! I'm not THAT bad!"
"Remember what happened on Easter? the foot prints on your mother's ceiling?" Shoto asked.
"W-well that was uh..you know..I got a big bag of those cream eggs..and..i didn't want them to melt..and Mom didn't have any room in the fridge!" Katsuki huffed, blushing. 
"That's not how I remember it..but fine. we'll go with your version of events. just not a lot at once, OK?" Shoto offered, smirking.
"Yeah fine. Whatever!" Katsuki sulked. "Get the Cap'n crunch, I'll get the candy."  
and with that he took off and Shoto just knew the brat would be coming back with a armful of sweets.
"he's lucky he's amazing in the sack." he muttered, and wheeled toward the Cap'n Crunch.

Coming around the corner after getting the brat his cereal, and picking up a ag of coffee for himself, Shoto just smirked seeing Katsuki coming back towards him, arm's fulled with big bags of mini chocolate bars, cream eggs and the like.
'And in accordance with the prophecy..' he thought but kept his mouth shut.
"Did you leave anything on the shelf for others?" Shoto teased.
"heh, yeah, but not for lack of trying." Katsuki said then noticed the coffee in the cart. "Ick, why do you drink that stuff when we have chocolate syrup and milk at home?" 
"because a certain sweet tooth glares at me when i go to use any." Shoto teased.
"heh. well you got me there. Alright, let's go and pay for this and get back home." Katsuki said quickly, starting to head for the check outs and reaching back to tug on the cart.
"Nice try. we still have something else to pickup." Shoto said.
"Come on, give me ONE more chance!" Katsuki whined.
"If I thought that would really make a difference I would. now come on." Shoto said and started to head towards the pharmacy end of the store.
"..This is bullshit! get them if you want, but I'll be waiting outside!" Katsuki growled and started to stomp his way out of the store, drawing attention from other customers.
Katsuki Bakugo, you get your butt back here right this instant or I'm putting all of your candy back!" Shoto threatened. 
"I'm NOT going and getting stupid diapers with you! Diapers are for babies and I DON'T FUCKING NEED THEM!" Katsuki yelled, apparently unaware of all the people looking at them as he stomped a foot but was turning and facing Shoto. 
At least he was unaware till a teenaged girl started to snicker.
"YOU GOT SOMETHING TO SAY BITCH?!" Katsuki growled, spinning around to face her, and Shoto moved quick.
Grabbing Katsuki by the ear he gave the boy a firm swat across the butt. 
"little man, that is eno-" He started, talking over the yowl from Katsuki, but even then he was cut off as a loud thunder poot escaped from the blonds backside.
"..Katsuki when was the last time you-" Shoto started to asked.
Katsuki's bowels were a fickle thing, and the boy could go for days without a movement, but when it was ready to come out, he had little to NO warning time.
"i..I.." Katsuki whined, and then with a crackling poot the back of his shorts started to darken and blossom out.
"N-Nooooo!" Katsuki whimpered and whined, but was helpless to do anything as days worth of heavy food destroyed his briefs and weren't doing the shorts any favor either.
the crowd was watching with mixed reactions, though most was amusement, at least until the smell hit them. and a few were just shocked at the mass growing in the back of the boys pants.
Shoto should of felt bad for him, but given he'd been acting like a total brat and he was positive had been about to use his quirk on that girl, he was all out of mercy.
"great, Just great. it's not enough that your wetting the bed every night, now your pooping your pants too?" Shoto asked, hands on his hips.
"I..But..I.." Katsuki whined. 
"that's it mister man, we're going and getting diapers alright, and NOT just for night time! and I'm putting that candy back, clearly junk food is the last thing you need."
Picking Katsuki up and carrying the mortified blond over to the cart, Shoto was sure that the blond knew what coming from the little bit of a fight he was able to put up.
It didn't do him any good though as Shoto sat him down with a loud squish in the baby seat of the cart. 
"MAYBE if you watch your mouth and behave, I MIGHT let you keep the cream eggs. but your on thin ice mister." Shoto said and shook a finger at Katsuki who whimper and started to bawl, even as the crowd started to clap and cheer in approval.
"one last thing, Say sorry to everyone." Shoto said, and stepped aside,.
Katsuki sobbed and hiccuped, and though teary eyes looked at the crowd.
"I.I'm sowwy." he lisped babyishly.
The crowd loved it.

After that Shoto wheeled the cart to the pharmacy area and picked up not one, not two, but three of the extra thick overnight diapers that the store carried, as well as getting some baby bottles and a package of pacifiers.
Katsuki started to wail loudly at that point so Shoto, after getting permission from a employee, opened the pack of paci and popped one in the smelly teens mouth.
part of the crowd had followed them, since well they didn't really get much excitement and this beat the re runs that were playing on TV at the moment anyways.
As Katsuki suckled on it and whined, a chuckle spread though the crowd.
Shoto also got permission to open one of the packs of diapers and was allowed to use the usually employee's only bathroom to get the little stinker changed.
the crowd helped up somewhat, offering to take back the candy as Katsuki got changed and Shoto just reminded them to leave a bag of the cream eggs for Katsuki, he had been behaved so far since going poopie.
Getting Katsuki in the bathroom, Shoto shook his head.
"I hope you understand you brought this ALL on yourself. if you hadn't of dragged your feet, or had all your little fits we'd of been home by now." he said, tugging the stinkers shorts off and tossing them in a trash bin.
Katsuki wisely kept his paci in, and nodded, but reached for his short futilely as they went though the air into the trash can. 
"no no, those shorts are ruined buddy. and I'm NOT buying you a new pair. you'll be waddling home in diapers." Shoto said, smirking and Katsuki laid on his back on the cold floor, fists going to his eyes and rubbing them as he suckled and whimpered big time.
Katsuki's lucky Ultra-man briefs were all but ruined and Katsuki paused in his crying to look down, then up at Shoto and shake his head no.
"Buddy, their ruined.I have to toss them." Shoto said.
Katsuki shook his head no again and brought his hands together, pleading.
"-sigh- alright..alright..you can keep them.. but I'm not carrying them." Shoto said, and then smirked as he took out a diaper. 
"Butt up."
Katsuki got a confused look on his face and pointed at his poopie undies.
"Yeah I know. they're still poopie. you wanna keep'em, you can wear them under your diaper, and YOU can wash them in the sink wen we get home." Shoto said.
Katsuki wrinkled his nose and shook his head no, going to hook his thumb in the waistband.
"No no no, You made your case, and won. enjoy the fruit of success." Shoto said and gently but firmly moved the brat's hands away. "Now butt up."
Katsuki started whimpering again even as he lifted his butt up and plopped back down with a squish on the soft diaper, and whined as Shoto started to sprinkle him with baby powder , then just took the top off of the container and dumped half of it in. 
"Don't wanna get attacked by a hoard of fly's on the way home." Shoto explained.
Taping the diaper up, Shoto helped Katsuki get to his feet and laughed at how cute and ridiculous the now big baby look, his legs bowed out and he was clearly having trouble walking, doing a weird baby learning to walk waddle.
As they started to head for the door, Shoto noticed that there was a black marker on a clip board on the door, for checking off a list of things to be cleaned and smirked.
"Hold it a second stinker." he said, grabbing the marker and then getting behind Katsuki, kneeling down and writing.
'Warning! Poopie diaper! (sorry about the smell)'
Putting the cap back on the marker and replacing it, Shoto lead the big baby out.

Their groceries, the ones they were keeping, had been taken up to a checkout as for obvious reasons the cart had to be cleaned, and the crowd chuckled and laughed, with some people even snapping pictures as Katsuki was lead, Holding daddies hand, to the check out. 
everything was scanned in fact save for the bag of cream eggs and the clerk gave Shoto a question look, smirking at the same time as Katsuki wiped his arm over his eyes and looked at Shoto hopefully.
"oh..I suppose. I'm just a big softie." Shoto said and leaned down, kissing the big babies head. 
Paying for the groceries and heading out the door with Shoto carrying the heavier stuff and Katsuki the light stuff, and the big babies hand in daddies, Shoto realized that his summer vacation was going to be even better then he could of dreamed, if not a little more smelly.

The end
