You were an emotionless person. You didn't show that you care, that you're happy, or whatever.

Then this guy, Tanjiro Kamado, decides he wants to make you smile and that he'll do anything for it.

But oh boy, was he wrong. You definitely didn't want him to make you smile.

But then one summer day, you and the pillars were asked to take a 3-day break at a beach for a summer vacation.

You were a descendant of Muichiro and inherited his breath, and with Muzan and the upper moon demons defeated, you guys can finally live in peace.

All that's left is to kill the remaining demons.

Tanjiro walks up to you and smiles. "Hey Y/n. Enjoying rhe beach?" He asks then sits down on your hammock.

You two were covered under the shade of the palm trees, and with the wind blowing gently as the burgundy haired boy's hair blew with the wind as well, you were at peace except for the fact he's here.

"Hey, Y/n, wanna hear a joke?" Tanjiro says and beams at you. "What's brown and sticky?" He smiles, clearly excited.

"A stick." You bluntly replied. "Way to go Y/n!" He chuces and tries to high five you, but since you wouldn't reciprocate, it failed.

"Now, what's white and sticky?" You ask. Tanjiro suddenly becomes flustered. "Uhh..."

"Glue!" You laugh, without realizing it. Covering your mouth, you look over to Tanjiro to look if he's seen it and yep. He has.

With his mouth agape and eyes sparkling, as if he had seen the beautiful view of the Milky Way right before his eyes, he smiles widely, grinning ear-to-ear. Cheeks a light shade of red, and him.

"Ahem." You said. "Sorry."

"No need to apologize Y/n!" Tanjiro says, grabbing your hands and shaking them. "Thank you for laughing! It's the first time I've seen it! It's so cute! Wanna head inside?"

"Sure."

.+*+.

The rain tip taps as everyone has went home. You're stuck in Tanjiro's hut as you're still in your swimsuit.

You could feel Tanjiro's gaze on you, before you hear the chair move and footsteps indicating he's gone elsewhere.

He comes back with a bathrobe and hands it to you slowly while you're gazing at the raindrops fall from the ceiling down to the floor.

"Y/n... can you wear this? It's not good for a cute lady like you to catch a cold or something." He smiles, and you take it, nodding and wear it slowly.

While Tanjiro was standing beside you, you noticed something poking you, though, you didn't mind it at all. Tanjiro sits beside you and you gaze at him only to discover...

He has a boner, and you have absolutely no idea what caused that.

Was it your body? Was it you? Was it your toned back or chest?

Tanjiro notices where you're looking. "Ah! Y/n! You aren't supposed to look there! That's naughty." He scolds you but not in a harsh way, it was more of a gentle and 'I'm here to change your life with my words' way.

"Sorry." You say, your face heating up. You knew you were blushing. You didn't know if you had the obligation to fix it, but definitely, Tanjiro has the body of a man so you were curious.

You realize that even you were growing a boner and that you wanted him in you.

But Tanjiro would definitely be a gentle boy.

"Hey, I'm gonna sleep on the couch. You take the bed okay Y/n-"

"Sleep with me." You urge, a hint of lust and plead in your eyes. You were sure he could see it. He got the hint, his face was red. He nods slowly, and he takes your hand and leads you to the bedroom.

.+*+.

Tanjiro locks the door. "Y'know Y/n... I've always loved you. That's why I wanted to make you smile." He says.

You blush, gulp, then say, "Tanjiro, I think I may like you too."

"Like?" He approaches you with dark eyes. "I love you Y/n. Can I show it? I'll be gentle. I promise. I won't hurt you, ever."

Despite the lust overcoming him, he's still the gentleman you've always known and loved. You smile at him. "You can go all out on me."

"No. I insist I won't hurt you." He says, slowly and gently pushing you down the bed.

You both undress your clothes, the fabric slipping away and slowly dropping to the floor. Tanjiro makes the first move, he pumps himself and posisitions at your ass. His eyes are asking for permission.

You nod, and he slips inside you, it hurt, groaning, your eyes closing in discomfort as your inside tries to adjust to his size.

"Uwaah! Sorry Y/n..." Tanjiro says, frowning. You give him a reassuring smile, though you were still hurting a bit, it was bearable.

"I-it's alright. I can m-manage." You say, trying to calm him down.

"If you say so..." The burgundy-haired boy's voice trails off. "I'll go real slow okay?"

You smile, then nod.

Slowly, Tanjiro starts thrusting in you, you can tell he's being real nice and gentle with you. It's your first time, and his too.

Suddenly, he rubs by your prostate, and the pain is slowly being overcome by pleasure.

"A-ah..!" You moan out, softly. You felt Tanjiro get harder in you.

"Is it okay if I move faster now Y/n?" He asks, still moving.

Right now, you're panting, trying to get used to the pleasure you're coping up with.

"Y-yes, please." You pant and plead out. As soon as he gets faster, you moan a bit louder, and it matches up with his thrusts, too.

Then, before you know it, you're a moaning mess too and so is Tanjiro just by listening to your moans.

By the time both of you each your climax, Tanjiro collapses beside you and lazily smiles at you, stroking your hair.

"Thanks for the wonderful night."

He says, as both of you fall asleep in each others arms.
