Chapter Text
Katsuki knew it was wrong. If Izuku found out, he'd never forgive him. He was putting seven years of marriage at risk for this.
But he couldn't help it. The temptation was too great.
Katsuki's hand pressed hard against his mouth to muffle the lewd groan trying to force through, trying to give a vocal legitimacy to his great sin. His eyes fluttered closed; he couldn't watch himself betray his husband like this, betray everything he'd stood for. He was a man of honor, of his word, and he was shattering it on the concrete.
Katsuki dropped his head into his hands, swallowing thickly to clear his mouth, shame and pleasure burning in his bones.
He was a cretin.
"Dude," Kaminari spoke up, glancing between a broken Katsuki and the rest of their friends. "It's just sashimi."
Katsuki's glare was watery, ineffective. How to make an idiot understand that seven months of no fish at all, in any form, even stock, had brought the Great Explosion Murder God Dynamight to his knees? Seven months of fulfilling Izuku's craving while ignoring his own, until now. But in doing so, he'd broken his promise to not eat anything Izuku couldn't. He couldn't hold out two more months to support his husband until their child was born.
He'd failed.
"Leave him alone, dude," Kiri said, waving off Kami's concerns. "Let him eat."
And eat Katsuki did, eat delicious bite seasoned with guilt.
