Cardinal sin

Groceries

"Put it back." Keigo murmured, not even looking up from reading the ingredients on the back of an oatmeal box. "I'm not buying that." He reiterated, sending you a challenging look when you made no move to take the box of cereal out of your cart.

"No." You replied simply, still looking at the options for more cereals. "I'll pay for my own damn cereal, anyway." You chuckled, picking up yet another box of the stuff.

"(Y/N), That shit is just sugar and sawdust." Keigo's tone bordered on dangerous then, he was getting annoyed."It'll rot your teeth." But you were in public. It didn't matter if he was annoyed here- hell, maybe it meant you can get more of his frustrations taken out on you later. "Not to mention the reason you get sick when you ear so early in the morning is probably because you eat shit like that instead of fruit and a protein." You enjoyed it so much the last time. "And I already warned you twice about you arguing with me over my paying for things." He reminded you, finally placing the oatmeal in his basket.

"I LIKE sugar and sawdust. If you won't pay for it I will, is all I'm saying. I'm not arguing with you." You defended yourself, dropping yet another box of the stuff into your cart. "And besides, what ever happened to 'nothing wrong with a sweet tooth?" You pushed your cart forward, but a single red feather floated in front of it, putting you to a strict halt. You looked around warily. "Kei! Careful! Someone could see." You whispered loudly, eyes wide as you turned back to look at him. He was closer than you expected. Your face came into contact with his torso as he towered over you.

"There is nothing wrong with it unless it negatively affects your health. Sugar should be a dessert. Not a meal. Put it back or else." He warned, his words not leaving any room for argument at this point. He was tired of your shit, and if you pushed him any farther, you would regret it, he decided. "You don't want to test me, (Y/N)." 

His tone sounded pretty fucking final for a guy who comes from a good back massage. 

You were not going to stand there and take it either. No, you had better plans. You could push his buttons. You LIKED pushing his buttons. There was just something so goddamn alluring about teasing and pissing off this god of a man while he struggled to keep a straight face. In the middle of a grocery store, you could probably get away with murder and he would just have to stand there and grit his teeth and threaten to 'deal with you when we get home'. As if you weren't excited for whatever weak ass punishments he would have in store, especially after he almost cried over a little bite. No, this man wasn't scary anymore. Not now that he was yours. Not now that you knew what made him tick. No, you were having way too much fun with this.

"Or else what, pretty boy?" You asked, an eyebrow raised. He was taken aback. You were so SMALL. So QUIRKLESS. And yet here you were, challenging him like you expected to win. He would never admit how much he loved it. He loved your stubbornness, he loved that you, despite how weak you seemed next to him, were still so willing to put him in his place. Not that he would EVER call you weak- no, because you couldn't be. You acted like you could kick his ass at the drop of a hat, and that look in your eye led him to believe if you tried, you probably actually could. But right now was no time for him to be impressed with you- not when the matter directly related to your health.

"Or I'll fucking spank you in the middle of this goddamn store." He leaned in close to whisper his threat into your ear. 

"Now be my good girl, little goddess, and Put. It. Back." He backed up, and returned to his own cart, pursuing the selection before him, leaving you a quivering mess. You put back one of the boxes. 'Good girl'?! In the middle of the grocery store?! Oh he was going to fucking GET IT. You had half a mind to reverse the game and spank HIM. All in due time, you told yourself. You would eventually give him exactly what he needed. Keigo Fucking Takami was an impulsive, temperamental, dramatic jerk who you wanted to show up more than anything in the world- and hey, if you failed, you wouldn't actually mind him spanking you all that much.
