Deku, Shoto, and Katsuki trudged into the building that housed their agency, silently riding the elevator up to their floor. They were all dirty, scraped up, and a little bloody from the raid earlier that evening, but luckily no serious injuries for them. They didn’t even need to see anyone with a healing Quirk. 

The doors opened and they slowly filed out. Deku and Shoto turned towards the locker rooms, Katsuki kept moving through their office. 

“Hey.” Shoto’s voice paused Katsuki’s movements. He turned towards the sound and raised an eyebrow at Shoto. “You don’t want to shower and change?”

“The sooner we get these reports out, the sooner we all go home.” Katsuki said definitively and turned back to their office, quickly walking to the conference room where he’d left his laptop and notes earlier. 

He sat down at the table and set to work. A few minutes later, Shoto joined him freshly showered with his hair still wet, water dripping onto his shoulders sporadically. Katsuki’s eyes traveled down and he saw Shoto was wearing the pair of sweatpants that Katsuki once pointed out really accentuated his package. Katsuki raised an eyebrow as his eyes lingered, but didn’t say anything. Instead he discreetly adjusted his pants. He knew Shoto well enough to know how this evening would end. 

Shoto took his seat just as Deku entered and the three of them worked on the reports they each had to submit, helping each other out as needed and talking through their memories of the last few weeks and the case. At some point Deku ran out and picked up food for a late dinner. This went on for hours.

“Whew, okay.” Deku finally announced, closing his laptop with conviction. “I’m done with my report.” He stood up and started gathering his things. “This has been a crazy couple of weeks. Are you guys done?”

“Almost.” Shoto said and Katsuki grunted. 

“Alright, well, don’t stay too late!” Deku waved as he left the conference room and walked through the vacant office. It was after 1am and everyone had been granted an evening and the next day off after the trafficking case they’d been working nonstop on over the last eight weeks. 

“I’ve got another hour of work.” Shoto announced. Katsuki hummed in agreement. “I could use a break.” He added and the suggestive tone dancing around his normally monotoned words had Katsuki raising his gaze to meet the mischievous glint playing in Shoto’s bicolored eyes. 

“Oh, could you, Icyhot?” Katsuki asked playfully. 

“I bet you could too, Blasty.”

Katsuki’s lips curled into a smirk. 

“You did so well today.” Shoto purred, knowing the effect it would have on his boyfriend. “Taking down those villains with ease.”

Katsuki’s dick twitched in his pants and he moaned. “More.”

Shoto stood up, moving to stand behind Katsuki and massage his tense shoulders, always sore from withstanding his powerful explosions. He leaned down and whispered in Katsuki’s ear. “You’re so strong, Katsuki.” He punctuated the statement with a nibble on Katsuki’s earlobe, sending chills down the man’s body. “Japan is lucky to have an incredible Hero like you.” 

“I know.” Katsuki whispered back as he turned his head and captured Shoto’s lips, swiveling his chair to face Shoto. 

Shoto blindly shoved Katsuki’s laptop away as their lips moved hungrily against each other, Katsuki’s tongue pushing eagerly into his mouth. He sat on the conference room table and Katsuki moved to stand between his legs. 

Shoto’s hands traveled down to undo the pants of Katsuki’s Hero suit. He’d shed the mask and gauntlets hours ago, but still hadn’t changed. Shoto tugged his pants and boxer briefs down to release Katsuki’s cock from the confines. It sprang free to attention in Shoto’s waiting right palm. He activated his Quirk to cool his palm as he started stroking Katsuki. 

Katsuki moaned into his mouth and pulled away, catching Shoto’s bottom lip in his teeth before releasing it. He pulled Shoto’s tshirt off and paused to admire his boyfriend’s physique before he leaned into Shoto’s neck, kissing and nibbling along his neck and shoulders. He felt the moment Shoto activated his left side and his dick twitched in anticipation. Shoto switched to his left hand, now rubbing Katsuki with a warmed palm. Katsuki moaned, kissing back up Shoto’s neck. 

“You like that? Shoto purred.

“You know I do, Shoto.” He moaned and licked up the puckered skin of Shoto’s scar, pausing to kiss his closed eyelid. “Beautiful.” He breathed, knowing Shoto still felt subconscious about the mark on occasion. 

Shoto continued alternating between his cool right palm and his warm left palm. The dueling sensations had Katsuki’s dick throbbing for release, but he didn’t want that to be in Shoto’s palm. 

Katsuki moved his hands to tug Shoto’s sweatpants down, lifting him briefly to tug them free before sitting him back down on the conference room table, closer to the edge than before. 

“You got any lube on you?” Katsuki whispered against Shoto’s lips. Shoto grabbed his hand and licked his palm, thoroughly coating it in spit. 

“Yes.”

Katsuki snorted. “Didn’t mean like that but it works.” He said, gently pushing Shoto to lay back on the table to get a better angle. One calloused hand gripped Shoto’s slender hip as the other ghosted over his taint and slipped between his cheeks, one finger teasing his entrance. Shoto moaned and Katsuki captured his lips again, wanting to taste those moans as his finger worked to stretch Shoto’s hole. 

He slowly slid another finger in, pumping in and out, scissoring to stretch his boyfriend. He slipped a third finger in and Shoto bit his lip and moaned. They stayed like that, dicks rubbing against each other, kissing, and Katsuki fingering Shoto until he felt stretched and ready. 

“Do you have a condom?” Katsuki asked, knowing he hadn’t replaced the condom in his wallet after the last time they fucked in the office. He resumed kissing and sucking Shoto’s neck. 

“Why?”

“What do you mean ‘why’ ? So we don’t make a fucking mess.”

Shoto gently pushed Katsuki so he could sit up and reach for his discarded sweatpants. Instead of coming out with his wallet and a condom, like Katsuki expected, he calmly retrieved a plug and set it on the table. 

Katsuki stared at it for a moment. “You little slut. You planned this.”

“Yes.” Shoto said simply. “Will you fuck me now?”

“Absolutely.” Katsuki growled as he lined himself up at Shoto’s entrance and pushed his throbbing cock in. “Fuck, Sho.” Katsuki moaned, reaching one hand up to pinch one of Shoto’s nipples. 

Shoto arched into the touch, moaning as Katsuki’s cock repeatedly pressed into his prostate. “Mmm, Kat. F-feel so g-good, mmm.” He moaned, voice pitched high in pleasure. 

“You’re not gunna last long, are you, baby?” Katsuki teased as he watched his boyfriend coming undone under him. 

“Nooo,” He whined. “Hnnghhh.”

Hot and cold hands tightened around Katsuki’s biceps as he thrust, losing himself in the feel of Shoto’s body wrapped around his cock. He watched Shoto’s face with a devilish smirk, waiting for that little crease to appear between his brows. 

“Mmm, K-kat-suki.” Shoto whimpered as the crease formed between his brows. 

“Gunna cum for me, baby?” Katsuki asked, his eyes snapping down to Shoto’s cock just as thick ribbons of cum spurted out, coating his abs. Katsuki bit his lip as he thrust erratically into Shoto, chasing his own release now. “Ahh, fuck, Sho!” He cried out as he came. 

The plug appeared in front of his face and he plucked it from Shoto’s hand, gently pulling out and replacing his cock with the plug.

“So much for not making a mess.” Katsuki said, swiping a finger through the cum on Shoto’s stomach and holding it up to his face. Shoto obediently opened his mouth and sucked his own cum off Katsuki’s finger.

“Towel.” Shoto said once Katsuki’s finger was clean and pointed at his gym bag sitting nearby. 

“You really did plan this.” Katsuki quipped as he put his dick back in his pants and retrieved the towel, wiping the cum off Shoto and the conference room table. He held out his hand and pulled Shoto to his feet. 

“Take me home, Katsuki.” Shoto said as he pulled his clothes back on and closed his laptop. 

“Thought you still had work.” Katsuki said as Shoto continued packing up his things.

“You rise with the sun regardless of when you go to sleep. We’ll come back and do it in the morning.” He said around a yawn. “Fuck me again at home.” And with that, he left the conference room. 

Katsuki smirked and packed up his own things. “With pleasure.” He said to himself. Over the years, he’d learned that Shoto turned into a horny little bastard as soon as they wrapped up a case and he was always eager to satisfy that itch. 

He waited by the elevators for Shoto to return from his office and they stepped onto the elevator together. Katsuki wrapped his arm around Shoto and the man leaned into his side with a yawn. 

“Tired?”

“Not tired enough.” Shoto responded as he squeezed Katsuki’s ass. Katsuki shook his head with a smirk playing on his lips as they exited the building and turned towards their apartment. He was just as eager for round two at home before they finally grabbed a few hours of sleep.
