“Kacchan, c-c’mon, this isn’t what it looks like--” Izuku stammered, emerald eyes wide.

“No, Izuku, I think it’s /exactly/ what it looks like,” Katsuki growled, his own ruby eyes narrowed to slits.
He crossed his arms, and tapped his foot, awaiting whatever pathetic excuse his husband would make.

Izuku was in bed, lights off, bathed in the glow of their TV.
Katsuki could see the guilty-ass look on his husband’s face all the way from the doorway of their bedroom.

Bottom lip out and trembling slightly, green brows knit, creating worry lines Katsuki desperately wanted to smooth…
No! Katsuki was supposed to be /mad/ at his husband, not thinking about how cute he looked!
Katsuki shook his head slightly.

“Well? Anything to say for yourself?!” Katsuki snapped.
“Kacchan, I--you were taking so long, and—I was going to—” Izuku started, only for Katsuki to hold up a hand, stopping him.

“Forget it,” Katsuki said flatly, turning around to leave.
Izuku’s heart was in his throat.
“Where are /you/ going??” Izuku asked, his voice going up an octave, causing Katsuki to glance back and give his husband a mock withering look.

Katsuki had /finally/ gotten baby Kaisei to sleep for the night.
It had taken longer than usual, Kaisei crying up a storm, refusing to be soothed.
Their firstborn definitely took after Katsuki, stubborn through and through.

But Katsuki had done it again! He’d gotten his fussy son to sleep!
He’d returned to his and Izuku’s room in high spirits, looking forward to watching /their show/ together as his reward.

Only to find that Izuku had started watching without him! How dare he!
“To sleep on the couch. I don’t want to sleep with a /traitor/ like you.” Katsuki huffed in reply.

Was he really that mad? No. But was he gonna give Izuku a hard time anyway? Absolutely.
Katsuki started to walk out.
He counted the steps. 1… 2… 3…

He heard a crackle, and felt the fabric of his sweatshirt press more against his torso as a tendril of Blackwhip curled around his abdomen.
Katsuki smirked to himself. /Gotcha./

“Kacchan… c’mon, don’t be like that,” Izuku pleaded softly, and Katsuki felt the gentle tension tighten further.
Katsuki turned up his nose in response, refusing to look at his husband.
“I’ll be however I damn well please,” he replied, straining against Blackwhip’s grip,but+

that was met with a gentle yank as he was pulled backwards. “Woah!”
The backs of Katsuki's legs hit the foot of the bed, and he fell flat on his back on the mattress with a /whump/, finding himself looking up at Izuku, who bent over him.

“I’m sorry,” Izuku said softly, green eyes shining, his lips in a tiny frown. His brow furrowed further.
Katsuki heaved a sigh of mock exasperation. “Well, I /suppose/ I can forgive you…” he started, tapping his chin, pretending to consider accepting Izuku's apology+

while looking up at Izuku cheekily through his lashes.
Izuku’s green eyes lit up and that frown turned into a little, bright smile.
Katsuki’s heart skipped a beat, and he broke into a smile of his own almost reflexively.

Damn it, why did Izuku have to be so…so…!!
“You’re so damn lucky you’re cute, Bakugou Izuku,” Katsuki said, reaching up and grabbing Izuku’s face in his hands.
Katsuki pulled his husband down for a kiss, eliciting a laugh from Izuku before their lips pressed together.

It was a bit of an awkward kiss, as Izuku was bent over Katsuki, and Katsuki was laying down at the foot of the bed from his crash landing.
Katsuki felt Blackwhip release him, as Izuku pulled away slightly.
Katsuki opened his eyes and noticed Izuku still looked guilty.

“Oh no no no, where do you think you’re going?” Katsuki said with a playful smirk.
“C’mere,” he growled, pulling Izuku down again, kissing every inch of his husband’s freckled face.
“How-” a kiss against Izuku’s freckled cheek.

“Could I-” a kiss against Izuku’s other cheek.
“Possibly-” a kiss against Izuku’s chin, stubble scratching against Katsuki’s lips, and Katsuki could hear Izuku giggling now.

Keeping Izuku in his clutches, Katsuki pushed himself fully onto the bed, sitting upright before his husband, before continuing.
“Stay mad-” A kiss beneath Izuku’s eye, brushing against the dark shadow that came with fatherhood.

“At this-” a kiss against the tip of Izuku’s nose.
“Face?” A slow, gentle kiss pressed between Izuku’s eyes.
Katsuki pulled back slightly and saw that goofy smile he loved spreading across Izuku’s adorable mug.

Izuku pressed his forehead gently against Katsuki’s, gazing into his eyes as the tips of their noses lightly brushed together.
“I love you, Kacchan” Izuku said breathlessly.

“I love you too, Izuku,” Katsuki replied with a smirk.
A pause.
“…you get diaper duty tomorrow and the next day though.” Katsuki said.

Izuku groaned with a defeated smile. “Nooo.”
Katsuki laughed. “That’s the price of betrayal,” he told his husband.
“…That’s fair.” Izuku replied with a laugh.
And then they leaned in and kissed again, their show long forgotten.
