katsuki promised he would spend time with shouto the day after his birthday and that they would go to the toy shop and his favourite ice cream place in the city centre.
Which explained why he was now wandering through the crowded shopping centre holding the hand of the now 8-year-old.
They passed a number of shops before the blond glanced down at the little boy gripping his hand. He had his own special place for the two of them but he would leave that for later.
“Where’d you wanna go first cutie?” he asked, slowly swinging their clasped hands between them.
Shouto gave a look like he was thinking, before giggling and pulling katsuki to a fairytale themed shop, complete with cute little outfits for children.
How sweet, yet his mind immediately filled with lewd images of the boy holding his hand wearing nothing but a princess tiara and covered in his c-
He was pulled out of his filthy thoughts by shouto trying to push on the heavy shop doors.
He gently reached out to open the door for the younger boy, guiding him into the shop with a hand on the boy’s shoulder.
They walked in and were greeted by shelved of costumes and child-sized manikins dressed in tv show characters clothes.
Upon entering the shop, a girl in her twenties approached them, one of the staff it seemed.
She glanced between shouto and katsuki be for talking “ hi, welcome how can I help you today”
Shouto was shy beyond compare, he hid behind one of katsuki’s legs and stuck a thumb in his bout. Some habits die hard he supposed.
“Just gonna look around. He really wanted to come here and pick up some stuff”
Clearly not noticing shouto’s attitude toward her, she nodded before leaning down to eye level with him.
Even worse, the poor kid can’t hold eye contact with most people.
“Anything, in particular, you’d like?” she asked in that annoying baby voice people default to when they speak to kids younger than 10, but received no response from the 8-year-old.
“He’s shy” katsuki explained.
“Ahh, they all are at this age. Well have a nice look around and call if you need any assistance.”
With that, she went back to where she had originally been leaving both of them room to look around.
There really was no end to how much merchandise and costumes were stacked up on top of one another.
“Well, go wild kid. Whatever you want you can have”
He was very willing to spend an ungodly amount of money on shouto if it would make the boy happy.
But shouto being the kind of child he wasn’t too demanding. He picked between a few all might onesies, Micky mouse ears, a Mario costume because he found the moustache that came with it to be hilarious and a few sweets and wands of the shelves.
Then something at the corner of the blonds eye caught his attention.
A tinker bell outfit complete with that ridiculously short dress and clear wings.
He skimmed the shelf for a size he thought would fit before calling shouto over.
He brandished the outfit like a prize as a sly grin slipped onto his face. The two of them had just recently watched the Tinkerbell moves while katsuki place shouto’s hands in his sweat pants the whole time because he truly was just that horny.
“Look what I found, remember how you said you thought the fairies were pretty. I just know youed look even better,” he said with such an inviting look on his face.
Shouto flushed with shyness.
“It would make me very happy if my little shouto put this on for me some time”
Shouto nodded and they went to the register once he confirmed that he got everything he wanted.
“Quite the haul you’ve got the” the cashier ringing them up said with a smile.
As she stacked their items into the two large bags, he received a text from Touya stating that he had left the house but forgot to leave the spare key and if shouto could spend some more time with him and just be picked up later from katsuki’s apartment.
He paid for the things they had bought and thought to himself, Touya, how much easier could you make this?
He replied saying he didn’t mind and grabbed the bags as he and shouto continued their day together.
They went to the ice cream place, stopped by at the arcade so shouto could try to win something for katsuki, he was very adamant about it.
Then finished the day with a nice lunch before finally heading to katsuki’s apartment.
It was a nice place. Not too big, not too small, just right for a single man in his 20s. He carried shouto in on his shoulders, settling the things they had got onto the couch before gently depositing the boy onto the empty seat left.
Shouto giggled once he was dropped on to the chair, swinging his legs back and forward.
Katsuki tickled his sides causing the boy to laugh even more them fall back into the chair. The older man leaned down and placed a soft kiss onto shouto’s lips before whispering against them.
“Wanna try on one of your gifts for me?”
“Mhm”
He got up rushing to the bag and pulled out the first one, which luckily was the one katsuki wanted.
He came back a few minutes in a ridiculously short green dress and wings, looking as cute as ever. He’d completely left out the tights that came with the costume, probably wasn’t sure how to put it on but that was all the better.
Katsuki sat onto the couch and spread his legs, gesturing for shouto to come over.
“You look adorable”
He lifted the boy to straddle his thigh, the dress riding up even further and creating an even more illicit view for the older man.
He slowly caressed the boy’s side and rocked him on his thigh.
Shouto followed the rhythm katsuki set and continued to hump the man’s thigh. The blonds hand travelled down to undo his belt buckle, undoing his buttons and pulling his zipper down to free his aching cock.
He stroked himself to full hardness watching shouto hump his lap and make cute gasping sounds.
After a while of just lazily stroking his shaft, katsuki stands up and positions shouto’s face right in front of his erection, the perfect hight, it’s like he was made for it.
“Gonna be a good boy for me?”
In response, shouto nodded his head enthusiastically and stuck his small tongue out, delivering kitten licks to the head of katsuki’s cock.
The older man felt a pleasurable shiver go down his spine and took a sharp breath.
He held the top of the boys head and gently pushed the tip into his mouth for shouto to suck on.
His small warm mouth stretched over the head of the older man’s penis, spit leaving the corners of his stuffed mouth as he sucked.
The boy’s hands reached up to hold onto what couldn’t fit into his mouth.
This wasn’t doing it so katsuki pulled out and sat the 8-year-old onto the couch, pulled the dress up his little pudgy legs and exposed his swelling cocklett.
He put the small prick into his mouth, going all the way down even enveloping shouto’s balls into his mouths tavern.
The younger boys hands gripped katsuki's hair strands.
“Ahhh b-big br-o-other katsu-kii” he cried out, whining and moaning like a pleased whore.
Spreading his legs wider and squirming around trying to get more relief.
He thrust his unsteady hips into katsuki’s hungry mouth, his little feet kicking about as he finally came with a loud whine.
The thin liquid coated katsuki’s tongue, testing like innocence and made him all the more hungry for every part of this little lamb.
Shouto’s body went a little limp. He always became so pliable and soft after he came.
Katsuki sat him up properly, leaning a knee onto the chair and pushed his cock into shouto’s now slack jaw.
“Ahh fuckkk” he cursed quietly to himself, enjoying the warm velvety feeling of shouto’s mouth.
With all his muscles relaxed katsuki could push farther down the boy’s throat, taking care to not hurt him, he began thrusting into the open mouth and held shouto’s head in place.
“Yaahhh ahh good boy. That mouth was made for my cock. Look how good you’re doing”
Shouto preened under the praises, staring up at katsuki with large shining doe eyes.
Seeing this, katsuki, slipped his phone out of his pocket.
He recorded the way his spit covered cock slipped between underaged lips, the way shouto looked up at him, wanting and Ernest, recorded the sweet sounds that shouto made every time he was praised.
After collecting sufficient late-night material, katsuki put his phone away and pulled his cock out to jack off in front of shouto.
He felt his testicles tighten with and fill with semen.
He pushed the head of his prick back into shouto’s mouth, reaching down to cup his balls as he emptied his seeds onto the boy’s tongue.
His cheeks fill up as he swallows, only a few drops drizzled out the corner of his lips.
Katsuki leaned down and they shared a kiss, he tasted himself on the boy’s mouth and smirked.
“Let’s get you cleaned up, we can watch some movies while we wait for your brother.”
He filled his modest-sized tub with warm water and honey and rose petal bath bomb. Shouto and he spent some time soaking in the refreshing water and he enjoyed the feel of the child’s soft skin against his.
The cuddled beneath the couch blankets till Touya comes knocking.
Katsuki instructed shouto to go up to grab his jackets the presents he received today, all but the Tinkerbell on that would remain with katsuki.
While the 8-year-old shuffled around, Touya and he engaged in casual conversation till they heard the small footsteps down the stairs.
Once the younger boy got down he slipped his shoes on a said his good-byes to katsuki, lifting both arms up for what katsuki had assumed was a hug.
When he leaned down, he wasn’t expecting shouto’s lips to graze the side of his own.
He tried not to show too much of a reaction, his head had been angled so their lips hadn’t connected, but it was close.
He played it off and planted an equally sweet kiss onto shouto’s forehead and waved the two brothers off, though he didn’t miss the slightly questioning look Touya sent his way as they left.
That was a close call.
