The last class at Aldera Junior High ended, with the teacher muttering something about a bathroom break. Katsuki sat at his desk as his posse walked over to him.
"Hey, Bakugo. Wanna head over to the arcade or something?"
"Nah. I gotta do something first. I'll see you there." They nodded as Katsuki relaxed in his seat.
He looked down and was more than happy about the school desks. The school board decided to change to desk so that there was a black cover attached the the stilts.
Making a cover for whatever happened or was happening in the space by his legs.
"Geez, they're almost like you with how they respond to my commands." Below his desk he saw his secret slutty boyfriend: Izuku "Deku" Midoriya.
The greenette was hungrily sucking his cock, the large girth would have made him gag; if he hadn't been doing this for a decade.
He'd been pleasuring Kacchan for most of his life, It had become second nature.
His flushed cheeks and sweaty brow made Katsuki grit his teeth and start forcefully moving his hips, not that Deku didn't like it.
Izuku continued his vacuum-like sucking until Bakugo reeled back in pleasure and dumped his load in Izuku's mouth — the hot white milk pumping down his throat.
Midoriya gulped loudly, pressing his freckled cheek against Katsuki's hard member, rubbing his lips against his mushroom tip. "Mmmmm, you taste so good~" He moaned happily.
"Jesus, you've become really good at mouthfucking." Izuku hummed to himself "Well I can't disobey your cock." He said giddily.
—10 Years Ago—
"Your penis is small." Katsuki muttered as the two first graders compared sixes in the bath.
It would be one of the last times they bathe together: with their innocence anyways.
The two members were completely different sizes, with Katsuki's being far longer and thicker than Izuku's.
"Look! My penis is waaay bigger than yours!" The child bragged. "S-stop!"
Katsuki grabbed Izuku by the ass and rubbed the two dicks together "Go on, admit it! I'm better than you at this too!"
"Ahhh! Sto...Stooop!" And for the humiliation of his cock, being inferior to his best friends, Izuku ejaculated.
The white substance covering Kacchan's member. Even though Katsuki briefly become worried, Izuku ignored him.
He couldn't take his eyes away from his cum covered cock. After that, Izuku couldn't help masterbating while thinking about his cock.
"I'll get some snacks. Start up the All Might Theory video." Katsuki commanded while Izuku sat on his knees "Okay!" He replied.
'I'm in Kacchan's room. It reeks of cum.' Izuku thought to himself. 'I guess Kacchan jerks off too...he strokes his large cock, and sprays his stick semen. It smells so sexy that...I can't hold back!'
Izuku looked at the ash blondes trash bind full of crumbled up tissues, each one full of his dried up duck juice. "Haah...hash..." He moaned as he then knocked over the bin.
'It smells like Kacchan! It smells like Kacchan's cock! His cum smells so much stinkier and thicker than mine! I like it — no, I like it! My sister is tingling." Izuku grabbed his crotch, his smooth skin rubbing his hard small member.
'I can feel a sweet throbbing in my belly...more...I want to taste more! Ahhh, I can taste the cum spreading through my mouth...I'm gonna cum, I'm gonna cum from this..." His ecstasy made his mind fly!
"...What're you doing..." And his flight ended in an instant as he saw a confused Kacchan "Deku?"
"I wasn't-! I was just!" Katsuki set down the bowls of Goldfish and smirked. "So your a pervert jacking off to my used tissues...you really are useless."
"Ah...Ngh, I'm sorry." Izuku crawled on his his knees and held on Bakugo's leg while he gently stepped on his erect crotch.
"So you admit it. You were stroking your dick to the smell of my semen." Katsuki stepped on his member harder, making Izuku quietly moan.
"Auuu...Forgive me," He begged while gripping his best friends' leg tighter "please forgive me!" Bakugo hummed to himself with his cheeks slightly flushed.
"You want me to forgive you? Then..." Kacchan pulled down his pants, his swollen dick spring out for the greenette to see "Then kiss my dick~"
The tip of his cock was pressed up against his wet lips, his hot ragged breath making Katsuki's pubic hair stand on end "Kacchan?"
"I'll make you my living cock sleeve." Izuku stared, his thoughts full of questions and anxiety.
"You'll take my cum anytime, anywhere. If you kiss my cock and pledge to become my personal human pussy, then I'll forgive you."
'I shouldn't- I can't, no way! There's no way I'll kiss it! I'm a guy, I want to become a hero...' Izuku grew a feverish blush as he then smooched Kacchan's cock.
That's when Izuku became a loyal obedient slut to Kacchan's dick.
"Mmm...Ahhh..." Izuku moaned loudly as Katsuki placed him on his lap.
"Yes...your body hasn't developed any secondary sex characteristics since you lost to my cock~" The blonde cooed "Did you know that when a boy loses to cock, he becomes a bitch?"
Kacchan pinched the smaller teens hard nipples "Your dicks size will never challenge me again." He placed his member under Izuku's plump firm butt "Your asshole can swallow my huge cock."
He slammed Midoriya down, his cries making Bakugo even hornier. Deku had been his cock sleeve for years. He was an outlet, a cat's-paw: a sex tool.
But even he had to admit...Izuku's body had kept him...addicted...for all these years, and it was getting worse.
There wasn't a day or night that he wasn't roughly fucking Deku senseless, his cries and moans becoming a white noise to him.
"Your asshole is my slutty meat hole now." He continued gyrating his hips, making Izuku hold onto the older boy's body for stability. No matter how many times they fucked, he always had euphoric pleasure.
Deku began drooling as his eyes went to the back of his head, his cries becoming louder and louder in the empty classroom. Katsuki decided to quiet his voice to not alert anyone.
Bakugo's rough kiss made the submissive sleeve silent, his soft moans making both parties cum, Izuku spraying his semen all over Kacchan's stomach, and Bakugo filling Izuku's thicc ass; cum spilling out of his fuck hole.
They stared at each other with their hot breaths and red cheeks, both of them exhausted but still horny "Want to do this at your house?" Katsuki uncharacteristically wondered.
Izuku smiled and nodded "I would like that. Mom needs more sleep anyways."
