It was just another average day in the Midoriya Manor.Arousal enveloped the air as usual.Within Izuku's kingly office he worked away on his many business offers and cooperate relations whilst beneath his desk his sugar baby turned lover resided.His puppy lay naked between his legs only dressed in a collar - which was inscribed with the words "Kacchan Izuku's Good Boy" - faux blonde dog ears and a blond dog tail butt plug shoved firmly up his ass.Izuku was indifferent and was very much used to his omega getting needy and wanting attention from his alpha so to be near each other more Deku worked from home more often than not.Kept warm inside of Katsuki's mouth was Izuku's fat cock stuffing him full.Occasionally, Izuku would give Katsuki head pats or a scratch under the chin while telling him how much of a good boy he was for him.Each bit of praise shot straight to Katsuki's forgotten cock and to his twitching hole.Katsuki yearned for his Daddy's undivided attention as his shaking thighs got thoroughly soaked with more slick at the thought of Izuku putting his large hands on him.He knew better than that so he'd continue to be a good boy and wait patiently for his reward.
Absentmindedly, Izuku caressed Katsuki's tear stained cheeks as he suddenly noticed he had a call awaiting him.A smirk plastered Izuku's face while he licked his lips hungrily.Gently, Izuku tapped the side of Katsuki's face to get his attention, "Puppy, you've got to be on your best behaviour for me.I've got a call so you'll have to be quiet." Now usually this wouldn't be a problem since this has happened a multitude of times in the past but of course Izuku just couldn't help himself.An expensive loafer clad foot pressed onto Katsuki's tiny pink cock eliciting a muffled moan.Izuku had the audacity to call him a bad dog as he answered the call.
While the call progressed, Katsuki couldn't help but seek out relief from Izuku's shoe since it continued to apply pressure on him.He humped his shoe desperately while trying to keep his voice down until all went out the window when Deku pushed down especially hard.A loud whine cut through the air.
"Excuse me for being intrusive, Mr Midoriya, but what exactly was that sound just now?"
Katsuki's stomach sunk.
"No need to worry it's just my dog.I think she's in heat."
A muffled moan or two released themselves from Katsuki with a shudder.It felt so naughty and very much dirty to accidentally make someone listen in on them.To make it even better, Katsuki felt so degraded to know his daddy simply saw him as a bitch in heat sucking his dick for attention later on.A hand found it's way onto Katsuki's cheek, which he eagerly leant into.Once the call with his associate ended Izuku fully invested his attention to Katsuki humping his leg beneath him. A chuckle resonated from Izuku's chest,"Look at you.So desperate and needy.Do you need daddy that badly that you'll stoop this low and hump his shoe,Puppy?" Katsuki shivered from the degradation and looked up through his long damp blond eyelashes at his Izuku whining quietly while his dribble trickled down the sides of his mouth.Originally Izuku had planned on having a quick glance and then continuing work but Izuku just couldn't help but want to cater to his needy Puppy.
'He's too cute!!I can't restrain myself any longer' Izuku thought to himself as he pushed his chair back causing Katsuki to unlatch from his now spit soaked cock - a groan slipping from his lips.Katsuki whined at the loss and pouted until he suddenly felt his mate's arms man handle him into his lap.An onslaught of aroused alpha filled his senses while his mate kneaded his ass.Katsuki's ass was soaking wet - thank goodness Izuku only ever wore his 'less expensive' suits at home.Izuku dragged open mouthed kisses from the column of his throat down to his pert b cup tits.Greedily, Izuku sucked, nibbled and even pinched at Katsuki's innocent buds.Katsuki's mewls and pants echoed through the walls while Izuku proceeded to cover him with marks all over his chest that would surely turn purple by the morning - at least he had the decency to not cover his neck with them like last time when Katsuki embarrassed himself by walking out the house with a turtleneck during summer.Head thrown back, chest heaving, Katsuki made a pretty picture that Izuku made sure of to ingrain in his memory forever.Soon his roughness dissolved into gentle kisses that were placed all over his face whilst Izuku mumbled (perverted) praises.
"Good boy."
"You're the best Puppy I could ever have."
"Perfect cockslut."
"I love your tits.Hopefully if I keep sucking on them they'll get even bigger..hehehe"
"You look so cute all desperate and stuffed full of my cock~"
"I love you so much, my sweet Puppy."
Before he could fully bask in the praise, Izuku tugged his collar tag making him come closer to him and nibbled on his earlobe,"Does my sweet Puppy want his reward for waiting oh so patiently for daddy's cock?" If Katsuki actually had a tail he knew it would be wagging vigorously.Like the good boy he is Katsuki knew better than to answer with words since puppy's don't talk so instead he lapped at Deku's face with his pink tongue.A smile spread across Izuku's face as he all but yanked out Katsuki's butt plug and plunged his two thick fingers inside of him.Slutty moans escaped Kastuki's puffy lips."Shit, you're so wet,Puppy." Izuku grinned at his mate's trembling lips.Katsuki wrapped his arms around his lover's neck and licked at Izuku's mating bite eliciting ragged groans from him silently telling him that he belonged only to his alpha in repsonse."Fuck Puppy,I don't think I can wait any longer if you're going to do such cute things like that." Izuku's nails left crescent indents on Katsuki's hips trying to restrain himself.Submissively, his puppy bared his neck with a pout on his lips batting his lashes at him expectantly.Izuku's patience wavered causing him to lift Katsuki up by his hips only to drop him right above his dick, spearing him.A squeal leaves Katsuki's throat at the rough treatment since Izuku doesn't give him anytime to adjust.This was one of Izuku's favourite positions since he could see his mate's beautiful fucked out face, kiss the living daylights out of him, litter him with love bites rather easily, play with Katsuki's tits and he could make him bounce on his cock.Katsuki couldn't keep quiet while he continuously grounded against Izuku's powerful thrusts that always seemed to leave him crying out.
Izuku's large hands came full circle around Katsuki's slim waist as he clutched tightly - the evidence of their love making would be very clear the next day - to use him like a human fleshlight. "You're so...ngh~ cute, Puppy.Wish you could see yourself." Izuku purred out with his head in the crook of his neck nibbling on his mating bite.Loud moans of pure pleasure fell from Katsuki's lips while he alpha continued to plough into him.Izuku trailed wet kisses from his mating bite to his lips dominating his tongue into submission.A naughty calloused hand made it's way in between the them and grabbed hold of Katsuki's tiny cock.From the contact alone Katsuki came loudly since he was so desperate for some much needed attention down there.Lips still connected with a thin strand of saliva Izuku smirked when he pulled away, "Who knew a needy bitch like you would cum so easily?" Dazed, Katsuki flushed a deeper shade of crimson from his words causing more slick to fall from his drenched hole while his alpha ruthlessly pounded into his sweet spot.Overstimulated, tears fell down his face while his alpha continued to search for his own release.Katsuki was essentially useless after he came so now all he could think of was getting his alpha his alpha off to get to the cuddling quicker.
"Puppyyy..fuck!You're sucking me in so nicely ahn~ are you trying to get me to cum faster?Such a bad boy."
A rush of strength suddenly overcame Izuku making each and every thrust harder and much deeper.A bulge formed on Katsuki's once flat stomach from the sheer impact.An alphan growl fell from Izuku's throat when he felt his omega squeeze right around him once more.A silent scream fell from Katsuki's lips as he came dry before being forcibly pulled by his hair into a passionate kiss filled with teeth and tongue.Each and every noise that fell from Katsuki was swallowed up in their soul shaking kiss.Muffled by their kiss Izuku lovingly crooned, "Love you,Puppy...Mine...So pretty...My good boy."
They pulled away gasping for air.Izuku's thrusts began to falter and weren't as deep as before.Yanking Katsuki's hair back to expose his neck he nipped at it harshly.Not too long after, he came deep inside his lover with a shout of his name locking them together with his fat knot.
Pants filled the air while they came down from their high before they whispered in unison,"I love you,Deku/Kacchan." Giggles erupted from them at the absurdity of it.Katsuki's voice was hoarse from the hours of cockwarming and crying out. Carefully,Izuku reached on his desk and grabbed some wet wipes to clean Katsuki off with.Soft purrs enveloped the room from the attention Katsuki received.Katsuki will never admit it but he likes being pampered by his alpha and he especially likes being the centre of attention.Sweet kisses were placed all over him as he observed the damages he had done to him during their passionate activities with little apologies.Izuku removed Katsuki's ears and his collar, placing them on his desk.Gently,Izuku held Katsuki's face and squished to place kisses on his nose.A small smile spread onto Katsuki's flushed face before he yawned and fell face first onto his alpha's chest."Tired?" Izuku placed a kiss on the top of his pouty lips that Izuku oh so badly wanted to bite but of course he didn't want to upset his fiery mate.A small nod was the only response he was given before another little yawn passed through his lips.Katsuki nuzzled Izuku's chest inhaling his scent before drifting off to sleep while purring softly.Izuku chuffed at his sleeping mate as he pulled out his desk drawer where a scented blanket resided.He didn't want his poor baby catching a cold after all.He placed it around his mate and then rested his head atop his.An arm wound itself protectively around Katsuki as he continued to finish up his work.
"Love you, Kacchan~♡"

This has got to be my favourite fic I've written so far.I like to think that in this Au Dkbk have an age gap (Katsuki is 24 and Izuku is 29 nearly 30).I hope you thoroughly enjoyed this as much as I did 🤣
