Katsuki leaned heavily against his locker. The fact he’d been required to return to the agency immediately after completing the mission had pissed him the fuck off. He was tired, sore, annoyed beyond belief. But most of all…he missed his Deku. Three weeks apart for an international mission wasn’t unheard of for them, but this one had dragged more than usual. Their coordinates had been off by a few clicks, making the techs in Katsuki’s ear scramble for new intel. Eventually, he’d just turned off his earpiece entirely and carried on alone. That had been his first mistake. The fucking connection took forever to restart when he’d finally caught up with his target, leaving him screaming for anybody to send backup. Those idiots sitting behind their computers were a waste of space in his opinion. Would have been better to have another hero in his ear rather than some foreign government agency.
Needless to say, Endeavor was pissed when he returned home. The tongue lashing Katsuki received was up there by way of reprimands, considering he’d been written up for this sort of thing before. Going off grid was decidedly looked down upon. Although, Katsuki was pretty sure his boss was more pissed that he’d walked out mid-rant. The explosive blonde snorted as he pried off his costume. The fabric was ripped and singed in various places, giving glimpses of his bruised skin.
Muscles screaming and joints cracking, Katsuki dragged himself to the showers. A rainfall of hot water drenched his skin and he groaned. Fuck, what he wouldn’t give for Deku to be here with him. Listening to his partner’s little mewls of pleasure as Katsuki sucked and nibbled at his skin, fingers lazily circling his rim. A breathy sigh escaped his lips as heat pooled between his legs. Three weeks without his lover was fucking torture.
Scarlet eyes disappeared behind heavy lids, and Katsuki fell back into his fantasy, imagining the water that beat along his back as Izuku’s fingers explored the expanse of his skin. The hand languidly stroking his cock became Deku’s perfect thighs. Sprinkles of water from the peripheral spray ghosted across his face and Katsuki sighed at the image of Izuku’s lips placing kisses all over his visage. The coil of heat in his belly tightened more and more as his fantasy became increasingly more vivid. Soft hands massaging into the meat of his legs as lips wrapped around his cock, taking him in one go. The languid pass of a tongue along the underside that sent shivers down his spine. Katsuki would thread his fingers through mossy curls both as a way to ground himself and control the speed at which Deku swallowed him down. He could imagine the aborted gasps and moans his lover would make as Katsuki tightened his grip on his hair and thrust to his heart’s desire. A long, low groan rattled in the explosive hero’s chest when he painted the tiles with his cum. His breathing came in pants, body leaning heavily against the cool shower wall as he watched his spend circle the drain. What a waste, Katsuki thought, imagining all the times he’d unloaded into his lover, enjoying the way his cum slowly leaked out of Deku’s fluttering pink hole.
The rest of his shower wasn’t nearly as gratifying. The water turned cool soon after, and Katsuki had to race to wash off all the soap bubbles before he froze. When he finally made it to his and Izuku’s apartment, exhaustion had fully set into his bones. He could barely keep his eyes open, let alone get the damn key into the lock. Somehow, Katsuki managed to make it inside without much of a racket. It was late, well into the night and he knew Deku must be asleep. Although sometimes the nerd waited up for him when he was due to return from a long mission. As Katsuki padded into the bedroom, he spotted a lump in the bed, tufts of green hair just barely poking out from under the covers. The steady rise and fall told the blonde his lover was fast asleep. Katsuki’s clothes were discarded, goosebumps settling over his skin. The chill didn’t last long as he slipped into bed behind his partner, the warmth radiating off Izuku feeling like the heat of the sun itself. Heavy arms wrapped around a freckled middle and Katsuki sighed contentedly at the feel of bare skin. So, Deku was trying to wait up for me, he thought, smiling into fluffy green curls. His thumbs rubbed circles into Izuku’s skin and the blonde pulled his lover tight to his chest. Just the heat and touch of their bodies so tightly packed had Katsuki filling out again. But this still wasn’t enough. He needed to be closer.
“Little shit,” he huffed softly, feeling the plug nestled between Izuku’s cheeks. Katsuki pulled on it experimentally, receiving a soft moan from the smaller man. Careful not to disturb him too much, he gently began easing the toy out, enjoying the way Izuku’s frame shivered in his hold as it no doubt teased against his prostate.
“Mmm Kacchan,” Deku hummed. There had been no change in his breathing.
“You dreaming about me, Baby?” Katsuki asked softly, cock sliding in to replace the plug. “Fuck,” he sighed. “So warm, so soft.” Nestled deep in his lover’s warmth, he couldn’t help but rub his fingers over the slight bulge in Izuku’s abdomen, shivering at the feel of his cock just under the surface. Finally, all that tight pressure that had been building in Katsuki’s chest over the last few weeks disappeared. He hummed softly into Izuku’s fluffy curls and tangled their legs together.
The smaller man stirred, his hole milking Katsuki’s length. “Kacchan?” Deku’s sleepy voice rasped out. His hand moved to feel the cock filling his insides and he breathed out a soft moan. “Welcome home, Love.”
“Glad to be home,” Katsuki hummed, placing a few lazy kisses along the back of his lover’s neck. The soft clench around his length radiated warmth throughout his body. Scarlet eyes grew heavy once more, sleep settling in. “I’m back where I belong.”
