"Ya like that, my good little slut?" he groans in your ear as his hips pummel your insides. He set a punishing pace right at the beginning, your body pushing and pulling along the sheets at the intensity. You find it hard to do anything but whine as his hips smack against your ass, his chest pressed into your back. Your fingers twist into the sheets, your face rubbing into the material in a pathetic attempt to muffle your exceedingly pathetic moans. You grasp at your pillow, pulling it to your chest as Katsuki's cock reaches deeper inside you, and your bite down on it as the word bubbles up in your throat.

You wanna say it. You want to, but you can't. You just know that he'd hate it. But as his dick pokes at the special spot inside you, it slips out anyway.

"Daddy!"

The world stops as your world stills, his cock halfway inside you mid-thrust. You fucked up. You know you did. You know that this arrangement was just for sex; a means of relieving stress for the both of you. You crossed the line. You fucked up.

He doesn't move an inch, his hardness leaving you feeling half-empty. Your shoulders tense the longer he goes without moving, without speaking. It may only be a few seconds, but it feels like hours of deafening silence. You can't manage to stop yourself from letting the tears silently slip down your cheeks, tremors passing through your body with the effort of holding back sobs.

After a tense moment, his quirk-heated hands smooth between your shoulder blades before he grasps your shoulder, turning you over slowly. In your humiliation, you drag the pillow with you, burying your face in the plush material as you're brought onto your back. You know you seem ridiculous, childish even, but you can't look him in the eye.

"Come out, my pretty baby," he says, his voice dripping over you like melted butter. The shock of hearing him so soft is enough to overwhelm your embarrassment. Pulling the pillow down your face enough to reveal your wide eyes, you look up at your partner. His expression is one that you'd never seen on the tough pro-hero before. Gone is his signature smug smirk, instead a soft grin takes its place. Quirk-softened digits delicately brush over your temple, smoothing at the wrinkles in your forehead. "There you are, my perfect baby. Need Daddy to take care of you?"

Oh. Oh. You definitely weren't expecting that.

His hips pick back up, the pace lazy, movements packed with power instead of speed. It leaves your mouth hanging open, each long thrust into you punching the air from your lungs and the pitiful whines from your throat. He moves onto his side, pulling you with him and tucking you into his chest as you both lay next to each other, facing one another. His palm glides over your thigh, maneuvering your leg over his hip as he continues his leisurely pace. Katsuki pulls the pillow clutched between your hands away, silently encouraging you to hold onto him instead. You do, hooking your arms under his arms and gripping at his shoulders. Your face buries into his chest, your mind slipping into a smaller headspace as the blond coos sweetly and pets your hair.

"Oh, my pretty little thing. Such a good baby. My baby. So, so perfect." You release a breathy whine, your body thrumming with the rare praise. The explosive blond always had such an affinity for nasty words, his tongue sharper than anyone you'd met before. You never knew he was capable of catering to your smaller side. You needed the affirmation, but never asked, afraid to ruin whatever was between you both. But if you had known that his words would set you alight like this, would would've called him 'daddy' a long time ago.

Katsuki peppers kisses and nips all over your face as he continues his unhurried pace. His arms cradle you to his chest, the embrace itself feeling more intimate than when he was brutally plunging his cock into you. That thought alone has you letting go in a breathy gasp, the sudden release causing you to clench down on him. It triggers Katsuki's orgasm and he spills into you. You're filled up by him, his spend swimming in your stomach and warming you up. And when the last ropes of cum flood your insides, he doesn't pull out. Instead, he pecks your sweaty forehead, trailing chaise kisses to your closed eyelids, your nose, your cheeks, your chin, and finally, your lips. He parts only a breath away, the tip of his nose tracing patterns into your skin as you both catch your breath.

"You did so well, baby," he whispers, his voice barely there. "Rest now. Daddy'll take care of you." His thick arms curl around you, dwarfing you in his hold as he curls up around you, his softening cock plugging you up still. It's perfect. It's everything you wanted.

Sorry for the short drabble, but I was in the mood for some sweet, slow, intimate sex from my favorite explosive blond.
