Telling him:
You peak your head out of your bedroom and search for your husband, Sanji. You can't see him but you realized you didn't need to after you caught the scent of baking brownies. He was home and of course, in the kitchen. "Sanji? Can you come in here, please?" you call out.
He rushes up the staircase without hesitation, hearts in his eyes. "Here I come, my dear! What can I do for you? Would you like me to cook you one of my signature beautiful meals? I made brownies as a dessert anyway!"
"No thanks. I appreciate it, though! I actually wanted to talk".
"Of course! I could spend my whole life just talking to you! What is on your gorgeous mind?" he asks, thrilled
"Well, do you remember a couple of weeks ago when we...went at it? Like, hard? ...And 4 times in one night?"
His entire demeanor changes on a dime. In a low voice he says "Oh, I definitely remember. You were an animal. Why? You wanna go another 4 rounds?" and places his hand on your upper thigh
You poke his nose and softly push him back. "I have something else in mind"
"Is that so?"
You walk closer to him and pull a pregnancy test out from your pant pocket, holding it up so he can see. He takes it from you and looks at it carefully, squinting
"So it's a positive pregnancy test. What's the big deal? I mean, it is positive so I guess it's a big deal to the future mother but-"
...
"Wait. Are you- are you pregnant?"
You nod.
Sanji drops the test and it lands on the floor. He leaps toward you and catches you in a tight hug. You wrap your arms around his shoulders and hug him back just as tight. After a few moments, he releases his embrace and begins twirling around on one foot with his hands cuffed together up to his chest.
"We are gonna have a baby! Our precious baby is on the 🎵 waaaayy 🎵 This is AMAZING! They are going to be the perfect angel; the definition of perfect!" he gets onto his knees and puts his hand on your belly "Salut, my perfect darling! It won't be much longer until this world is blessed with your presence!"
Delivery or soon after:
"You did great, baby. You were so strong and got our little angel here safe and sound" Sanji says after he kisses you.
You suddenly hear knocking at the door to your hospital room and hear a voice following it "I wanna see the baby! I have never seen a brand new one, ya know!"
"Stop it, Luffy! She delivered less than an hour ago! She doesn't need you barging in! HEY! ARE YOU LISTENING TO ME!?"
"What now? I told the doctor to leave us alone for awhile. Do I need to kick him in his face to understand that?" asks Sanji, clearly irritated "I will see who it is". The blonde man walks over to the door and opens it.
Luffy falls straight forward and his face plants onto the tile floor.
"Luffy? What the hell are you doing here?!"
Koby comes up behind Luffy shortly after breathing heavily with his hands on his knees, head down. "I'm sorry...Sanji...[Y/N]... I tried to...stop him".
"Will someone tell me what the hell is going on?" he demands, softly kicking Luffy's limp body
"I wanted to see the baby!" Luffy exclaims, words muffled with his face still smashed into the floor.
"Like hell you will! Get out of here! I told you you guys could see them when I sent the doctor down to the waiting room to get you!"
The straw hat-wearing man rises up and looks in your direction, noticing you holding the newborn close to your chest. "Oh, man! Look how tiny it is! Is it a boy or a girl? Oh, let me guess! It's a boy, isn't it? Haha! He can be the prince of the pirates!"
"It's a girl". Sanji snaps
"I want to hold her! Can I?"
Sanji extends his leg out against Luffy's chest preventing him from going any further.
"You won't touch my perfect angel!"
"Come on, Sanji. Pleeeaassee?"
"No. I bet you didn't even know how to hold a baby!"
"Do too!"
The two go back and forth until Koby speaks up "Let's just go back downstairs, Luffy. [Y/N] and Sanji will let us know when we can come back up for a proper hello. Now come on!"
"Fine..." he pouts
"You can come say hello if you'd like, Luffy" you interject
Luffy's eyes light up with joy and skips over to you
Your husband gasps and asks you "Huh!? You can't be serious, teddy bear! He will get his hands all over our flawless daughter!"
"A simple greeting won't hurt anything" you reassure him
"...Well, fine, but if you so much as make her cry a single tear, Luffy, I will kick your ass right out this window".
Walking closer, the rubber man gets right next to you and bends his neck down to get a look at your daughter. "Wow. She is tiny! What did you name it?"
"We decided to go with Sakura"
"Sakura is a great name!" Koby says from the doorframe. He never left it.
"Yeah, it is. Now. Get. OUT!" Sanji orders the two.
Future:
Your daughter is getting ready to spend time with her friends. She puts her shoes on and nearly makes it out the front door but is stopped by her father.
"My deeeaaarrr! Wouldn't you rather spend time with your dad? We can go shopping or go for a walk!"
"I can't, dad. I told you that I made plans this weekend. Maybe next week, alright? I gotta go. I love you". She leaves shutting the door behind her.
Sanji lowers his head in defeat, arms dangling "Why won't she hang out with me?"
You chime in from another room "She is 16 now. Teenagers go through a phase where they want to be independent and find it...not so cool to hang around their parents. Please don't take it too hard".
He lifts up his head and takes in a deep, sharp inhale.
...
"I WILL HAVE THE MOST EXEMPLARY MEAL PREPARED FOR HER WHEN SHE RETURNS!"
