Chapter Text
“Kachaan?” Izuku called out softly.
“Hmm?”
“…Can I love you, tonight?”
“…Fine.”
Izuku moved closer, wrapping his arms around Katsuki’s neck. He leaned in just as his husband did, their lips crashing like waves on a shore, relentlessly and insistently. Izuku’s tongue searched for Katsuki’s, tangling them passionately.
“Why so suddenly? You horny or something?” Katsuki asked between kisses.
“Just wanted to enjoy this while I can.” Izuku hummed. “Besides, it’s been a while since I was in charge.”
Katsuki scoffed at him, but let himself be overpowered by lust, both his and Izuku’s.
Izuku pushed Katsuki on his back, straddling him. Their tongues still danced in a frantic, sexy salsa, only allowed to be parted when Izuku’s shirt (which was actually Katsuki’s) had to come off.
Izuku sat up on Katsuki’s lap, pulling his shirt off slowly, being sure to flex and stretch, keeping his sultry gaze trained on the man below him. Izuku’s muscles typically made Katsuki go crazy. Tonight was no exception, as Katsuki looked upon him like he was a platter of food and he was a man who hadn’t eaten in years.
Katsuki put his hand behind Izuku’s neck and pulled him forcibly back to his lips, devouring them hungrily. Izuku bit his lip, tugging on it gently. The explosive man moaned hotly, grinding his hips against his husbands, eliciting a moan similar to his own.
“K-Kachaan… S-so good…” Izuku mumbled softly, grinding his hips back. Katsuki made an almost squeaking sound, one he’d made so many times before, but only they would know of. Izuku was the only one who would get to see him so vulnerable, and vice versa.
“D-Deku. Need you.” Katsuki ground out between moans. Izuku chuckled seductively.
“I know.” Izuku began mouthing Katsuki’s collarbone, sucking on various places, then licking over them. Occasionally, he would blow over a spot, making Katsuki shiver with desire. Izuku bit roughly into Katsuki’s neck, making the blonde hero arch against him with a loud moan.
“D-Dammit, Deku. S-stop teasing me!” Katsuki exclaimed, his palms sparking lightly over Izuku’s back. Izuku shivered; he’d come to love Katsuki’s quirk on his back, his hips, anywhere really. His high pain tolerance came in handy when Izuku was in charge, as Katsuki tended to literally explode when he came, but the green-haired hero had come to love it. And the hand-shaped marks that came after were like love bites; he loved them, but he’d definitely have to cover them up.
Izuku chuckled again, a little softer. “Impatient, are we?” Katsuki slammed his hips into Izuku’s, making him make a choking sound from the sudden onslaught of friction.
“Fuck yes.” Katsuki moaned. He moved his hands to Izuku’s hips and began to rid him of his sweatpants. “Help me take these off before I burn them off.” Izuku hurriedly lifted his hips, lying back and kicking the sweatpants along with his underwear off before Katsuki went through with his promise; he’d lost many pairs of sweatpants because of Katsuki’s impatience. He wasn’t losing another pair.
“Now yours.” Izuku reached down and grabbed the waistband of his sweatpants, pulling them down, only then realizing his husband hadn’t even been wearing underwear. “Did you expect this or something?” Izuku gaped at his husband, open-mouthed.
Katsuki shrugged. “Nah. It’s the middle of the summer, too damn hot for underwear.”
Izuku shut his mouth and continued to take the sweatpants off, letting the explosive man’s erection loose. Katsuki shivered at the air around him and cursed.
“Hurry up! I’m getting cold.” He complained. Izuku happily obliged, leaning back down and running his scarred hands along Katsuki’s sides. He connected their lips feverishly, letting their tongues dance in open mouthed kisses that left little to the imagination. While his husband was distracted, Izuku reached for the bedside table, opening the drawer and retrieving the lube and a condom. He coated his fingers with the lube generously before positioning Katsuki’s legs over his shoulders and probing his entrance.
“Ah! I-it’s fucking cold!” Katsuki hissed. Izuku pushed one finger in tentatively, moving it around gently and slowly, kissing him languidly until his expression of discomfort had faded into a calmer expression. He added another one, pushing it in and scissoring his fingers softly, so as not to hurt him. Katsuki winced when Izuku stretched too far at a point, making him flinch slightly.
“S-sorry.” Izuku kissed him softly as he added a third finger, just to be sure. It had been a while, at least a few months, since Izuku had last done this. Katsuki flinched and moaned loudly against his lips when Izuku brushed that one spot, that sweet spot that hadn’t been touched in months.
Izuku stretched him a little longer before pulling out, leaving Katsuki’s hole open and wanting. Katsuki whined when what he wanted wasn’t immediately there.
“F-fuck! Just h-hurry up, Deku!”
“Give me a second, Kachaan, I have to put the condom on.” Izuku opened the condom wrapper with his teeth, then rolled it on quickly, covering it in lube before he positioned himself at his husband’s entrance. “A-are you ready?”
“Yes.”
Izuku pushed in slowly, leaning forward to place open-mouthed kisses on the explosive man’s torso and stroking his dripping cock, so as to distract him from the slight pain of being penetrated. Katsuki hissed as the head made it’s way into him at a snails pace.
“D-Dammit, Deku, j-just push in! The head’s the worst!” Katsuki scrabbled for purchase on Izuku’s back to pull him forward, farther into him. Izuku panted as his erection was forcibly engulfed by tight warmth.
“K-Katsuki… You’re so warm… A-and tight…” Izuku panted, laying his head on Katsuki’s shoulder to find his bearings. Katsuki dug his nails into Izuku’s back, tiny explosions dancing along his fingers and palms.
Izuku pulled out slightly, then pushed back in, almost feeling his legs give in from the feeling. Why had it been so long? Izuku loved this feeling. Sure, he loved having that feeling of being full, that feeling of fulfillment that came when Katsuki was inside him. But this… This was mind-blowing to him.
“Gah hah…” Izuku huffed quietly, trailing his lips along Katsuki’s collarbone and leaving trails of saliva in his wake. He began moving again, this time in a steady rhythm, beginning the symphony of heavy breathing with his husband and himself to be the only players.
Izuku clutched the sheets and sped up his pace, driving himself deeper into Katsuki to find that one spot, that one--
“Th-there! Right fucking there, p-please don’t stop!” Katsuki clawed and crackled at his back, undoubtedly leaving various marks from his nails and his quirk. Izuku began picking up his pace once more, having faltered when Katsuki had his outburst of pleasure.
Izuku’s hips rocked into Katsuki’s sweet spot repeatedly, creating the delicious sound of the slapping of skin on skin, and his husbands loud moans and keens. Izuku continued to pump his husband’s erection, sporadic and quick from practiced motions.
Soon, their breathing became erratic, sweat almost pouring off of them.
“C-close, Katsuki.” Izuku sputtered, his hips rocking on their own in a spastic rhythm, his hand still pumping furiously.
“M-me too, Izuku.” Katsuki continued to claw at his back, until he suddenly grabbed his hips and yelled. “I-Izuku!“ White ropes of come spurted onto their torsos, painting their stomachs and Izuku’s hand white. Izuku came soon after with a yell of his own, the pressure of Katsuki’s tightening too much.
“K-Katsuki…“ Izuku cried weakly. After a few moments of catching their breath, Izuku slowly and gently pulled out, pulling off the condom and tying it off before throwing it into the wastebasket by their bed. Izuku then took a few minutes to clean them up, and laid back down next to his husband, snuggling into his side.
“I forgot how much fun that was.” Izuku giggled, tracing a love bite he’d left there hardly minutes before. Katsuki grunted in response.
“I guess it was okay.” Katsuki replied, twirling some of Izuku’s hair around his finger.
“Okay? That’s not what it sounded like. It sounded like you really enjoyed it. Judging by your volume, I mean.” Izuku smiled cheekily as he felt the explosive mans hands popping in embarrassment.
“Sh-shut up!” Katsuki sputtered. Izuku laughed at him quietly, then laid his head on his chest.
“Kachaan?”
“Hmm?”
“What do you think our kids will be like?”
A pause. “I… I dunno. I guess they’ll look like us. Why?” Katsuki frowned.
“Just wondering what you thought. Do you think I’ll be a good m-mother?” Izuku asked, not meeting his gaze.
“Of course. And anyone who thinks otherwise will be exploded.” Katsuki deadpanned.
“Kachaan! You can’t blow up everything that upsets you!”
“Oh, yes I can. It’s worked perfectly in the past.” There was a comfortable silence following the statement.
“Hey, Kachaan?”
“What, Deku.”
“I love you.”
“I know that, you Shitnerd.” Katsuki paused. “I love you too.”
