Could you possibly write about y/n calling Sebastian 'Daddy' for the first time and his reaction.
I'm thinking it'll be after a heated argument, which you took too far. And now you're trying to win back your grumpy boyfriend.
You follow him around the house, apologizing incessantly.
"Sebbyyyy, I'm so sorry. I know I overreacted, I trust you completely and I know you'd never cheat on me, just-"
He'd give you a glare which spoke volumes. And it'd shut you up.
When he'd walk out of a room, you'd follow his footsteps like a lost puppy.
You knew he usually wouldn't be able to resist you for long. But today was a bit much.
He had managed to completely ignore you for almost 3 whole hours now.
And you were upset, and very, very ashamed of your behavior. And the silent treatment was killing you.
You walked lazily over to where Sebastian was; in his study, sat on a couch and going through a script.
You plopped down on the couch next to him.
You were wearing one of his hoodies, and he usually would not stop telling you how much they suited you better than they did him but today, he wouldn't even spare you a glance.
"Sebby" you whined like a spoilt child.
"Daddy come on! I said I was sorry" you whined again tugging on the sleeve of his shirt.
And the words which left your mouth shocked both him and you.
He raised an eyebrow at you, finally looking up from the script in his hands.
"What did you call me?" there was an unfamiliar tone lacing his words. Almost playful but stern at the same time.
He sounded like he was mocking you, and seemed to like every second of it.
"I- uh... Nothing. Are you done being mad at me now?" you asked, worried that he might think you were being too childish.
The stern look didn't leave his face as he pulled you onto his lap quite harshly.
"No. Not quite. Now answer me, what did you call me just now?" you had never heard him use this voice before.
He stared deep into your eyes as though daring you to defy him again.
You didn't answer him. You were too shy to repeat it again.
"Alright then, have it your way" he spoke and manhandled your body in such a way that he had you lay over his lap, with your ass in the air.
He moved the hoodie, exposing your butt and he very briefly caressed your skin before you felt him smack your ass cheek.
You cried out. Not out of pain, but surprise.
A twisted part of you liked it, but you would never tell him that.
"I'm gonna ask you again, baby. What did you call me?" he sounded so dangerous but so hot...
You simply whined again instead of replying.
This time it hurt. And you finally spoke up.
"Daddy! I called you daddy. I'm sorry, Seb. I just-"
He cut you off by pulling you up and settling you on his lap; making you straddle his thighs.
He didn't seem to mind it one bit, in fact, he seemed rather intrigued.
"You've been bad today, baby. Daddy's upset that you'd even dare to think that he'll ever cheat on you" he spoke, while his hand caressed your red butt.
Something about how Seb referred to himself as "daddy" turned you on immensely.
You looked at him with curiosity; eager to find out where he'd take this.
He was much more dominant in bed that night. He had you begging, pleading him just to let you come
He liked how you surrendered completely.
Many things changed after that day.
He wasn't weirded out by it or anything, in fact, he quite liked it.
He liked being your big, strong man who could care for you like no one else ever could.
Seb was quite a gentle lover, yet the moment you'd call him 'daddy', he'd switch immediately.
It could be anywhere; at home while you would be lounging around.
Or while on the phone when he was away.
He'd go into "daddy mode" whenever you'd like him to.
Or, whenever you were acting up and being a brat.
He'd use his hand to pin you down on the bed or against the wall.
"Why do I even put up with you, huh? Why are you being so fucking difficult today, baby?" he'd ask on days when you were being too bratty.
Then you'd smirk and tell him that all you wanted was his attention.
"Yeah? Well then, work for it"
He'd point to the ground, in between his legs where he'd want you to kneel and take his cock into your mouth and show him that you even deserved his full attention.
Seb would be the best daddy to you.
He'd know when to push your limits and when not to.
He'd know when he could edge you for hours.
And when he could fuck you to sleep.
On days when you were particularly good, he'd even let you sleep with his cock buried deep in you
"You've been a good girl today, baby. You get to keep daddy's cock warm all night. You'd like that?"
And you'd nod a bit too quickly.
Then the following morning you'd wake up feeling tingly because daddy would be slow fucking you until you woke up.
Daddy Seb had a way of making you feel filthy and special at the same time...
He'd look you dead in the eyes, with his hand wrapped around your throat, while he made you come over and over around his cock
He took immense pleasure in making you cum for him multiple times in one night.
He would flick his tongue over your clit until you were shaking under him.
He'd always have to touch you when he was in the mood.
Dirty talk with daddy Seb? YES
"You like being on your knees and showing daddy how much you deserve to be fucked all night long, don't you baby?"
"Here, suck on daddy's fingers while he eats you out, yeah? That'll keep you quiet"
"Look at you, always so fucking ready for my cock"
"Your body is fucking shaking, baby. Is it because of me?"
"Did you ask for permission before you cum?"
"Swallow it all, baby. Show me you're daddy's good girl"
Sure, you didn't need him to be in "Daddy mode" all the time.
But on some days, he needed it more than you did
You could tell when he needed to let off some steam. And you were more than happy to be his little girl whenever he needed you to.
OMG could you imagine him switching from Sebby to Daddy in the middle of a heated discussion?? Because i CAN?
You'd be telling him off for being too jealous or possessive for whatever reason
And he'd suddenly give you this very stern look
"...you need to get your shit under-"
He'd cut you off by gripping your jaw in his strong hand and forcing you to shut up and look up at him.
"I fucking dare you to complete that sentence, babygirl"
And you'd immediately forget what the fuck you were saying in the first place.
Spanks... When you were naughty. Or nice.
He didn't care, he simply liked seeing his handprint on your butt.
He'd grab your butt, and pinch it all while giving you a gentle kiss on your forehead.
Ohh, aftercare with Daddy Seb?
He'd be the most gentle boyfriend after an intense play time
He'd run you a bath and would carry you to the tub and back to bed if you were too tired to walk
He'd kiss every inch of your body
And rub lotion on your sore skin
He'd tell you how good you had been and just how much he loves you
"I'm sorry baby, was it too much? Was I-"
"Shh, no. Hey, you were perfect. Thank you, I love you."
A/N: I'm sorry Anon, you were saying...
