"Hello"

> Sunshine! Where are you? <

"Home"

> But I was supposed to pick you up from the dorms. What happened? <

"I don't wanna talk about it"

> Kyunnie? Hey, did someone bother you? <

"..."

> I'll take that as a yes. Who should I beat up now? <

"You can't beat him up"

> Wa? Of course I can! <

"He's stronger than you, hyung"

> Pfft I can take anyone who bothers my BabyKyu! I will knock him down and make him wish he wasn't bo- <

"It's Kangin hyung"

> Oh <

"You were saying? *giggle*"

> You evil brat. What did he do? <

"Tease me"

> About what? <

"*sigh* what else? You as usual"

> *smile* What about this time? <

"He saw your ID on my phone"

> Uh-huh? <

"The name I'm saving your number under..."

> Oh, I see <

"It's getting really old this teasing thing"

> Well, it's 'Hot Stuff' and you're not really used on showing such cheesiness in front of the hyungs, baby <

"It's not cheesiness! It's just a freaking nickname!"

> So you don't think I'm a 'Hot stuff'? <

"That's not the point, Won!"

> Okay sweetheart. Now stop being upset, you know Kangin hyung loves you <

"Tsk... I know he does, but I don't like the ongoing tease by all of the hyungs! I mean come on! We've been already dating for years!"

> Maybe they're just jealous because neither one of them is as lucky as we are <

"How lucky?"

> Well, even if the other hyungs are dating as well, it's not the same. We're in the same group and we're most of the time together. We understand each other and how tough our careers are. It's very critical to date one of your band mates but it worked like magic with us because we're sincerely in love <

"*blush* you're logically cheesy, wonnie!"

> That's cuz you make me smarter, honey bear <

"*eye roll* so they're jealous of us?"

> You can say that <

"Well, I know one or two of them who want to date me"

> O_O What? Who? <

"I mean let's face it, I'm very much desirable"

> I'm desirable too! <

"Not among the hyungs, you aren't"

> Well, you love me <

"We still haven't figured out why yet"

> Kyuuuuu~ <

"*chuckle* you are very desirable to me"

> Obviously! *pout* <

"Hahaha"

> So about those who want to date you? <

"Well, Sungmin hyung seems to have a thing for me"

> What? Did he tell you that? <

"No. But like I said... I'm desirable"

> So would you have dated him if he confessed first? <

"If you weren't in the picture?"

> Yeah <

"Well, if you didn't exist in my life then..."

> *gulp* <

"Naaah he's not my type"

> *sigh* What exactly is your type? <

"It's pretty much summed up in two words"

> Which are? <

"Choi.Siwon"

> *beam* You're being so cute today, cutie pie! <

"And you're taking too long to get here, hot stuff!"

> I'm already on my way. I'll be there in a couple of minutes <

"I miss you *pout*"

> I miss you too, babe <

"Kangin hyung is gonna regret teasing me!"

> Come on baby! He was just joking with you <

"So, I'm gonna joke with him as well!"

> *head shake*... Kyunnie? <

"Hm?"

> No competitors, right? <

"What do you mean?"

> You're desirable and there's no way to hide that fact <

"What's your point?"

> I know people can't help but fall for you, but... <

"*smile* no competitors, hyung. It's only you"

> You have no idea how glad I am to hear that <

"Are you here yet?"

> I'm parking... <

"Yey!"

> *grin* see you in a minute? <

"Hmmm"

> I love you... I'll tell you your nickname of the day when I see you. I wanna witness your reaction <

"Pfft... as if I still get affected"

> We'll see... <

As the elevator sets in Siwon's floor, the man eagerly walks down the hallway and heads to his apartment with fast steps. Just as he's about to insert the pass code, the door swings open and his missed lover stands before him with eyes full of love and tender.

"Siwonnie~"

His delicate voice always manages to pull Siwon toward him, engulfing him in his embrace before pushing the door close with his foot.

"I miss you"

Kyuhyun shyly smiles, burying his face in the crook of Siwon's neck as he tightens his grip around his neck.

"I miss you too"

Siwon beams, pulling away enough to let their gazes meet, noting the endearing blush on his lover's face and caressing it with his thumbs as he whispers...

"I love you so much... Pookie!"

Kyuhyun's eyebrows furrow at his latest nickname, weirdly eyeing Siwon who smilingly clarifies.

"You know those pokemons you watch?"

"Uh-huh"

"Aren't they cute?"

"Uh-huh"

"Well, you're even cuter and Pookie fits you perfectly"

The explanation makes Kyuhyun roll his eyes although he can't help the deeper blush that adorns his cheeks, or how the corners of his lips twitch into a timid smile. 

"Tsk" 

That's all he can say, playfully punching his boyfriend's chest before cutely dangling his head a bit down as he starts playing with Siwon's buttons.

"And another thing..."

Kyuhyun tilts his head and questionably looks at Siwon who leans down and kisses his cheek before adding "You're also very poke-able, so pookie stands for that as well"

Kyuhyun yet again rolls his eyes before shaking his head in disbelief at how his boyfriend's little mind works.

"Pookie? Why so shy?"

Siwon continues his teasing, loving how Kyuhyun is quivering in his arms when his index finger reaches to poke his chubby cheek.

"Don't push it too far, hyung!" Kyuhyun warns, although his tone isn't intimidating at all and it only makes Siwon chuckle at him before pulling him nearer again and closing the gap between their faces.

Tongues mating and twining in sync, moans and groans echoing around the house, hands touching all over each other's bodies, and love words are whispered whenever they get the chance... Soon they're already lying on their bed, clothes scattered on the floor and bodies aching for each other's touch.

"I'm lucky"

"I'm luckiest... Pookie"

"Tsk... I hate you"

"I love you too! Pookie boo-boo!"

Seahorse wanted something about Kyuhyun being teased by Kangin about the 'Hot Stuff' nickname, and this is what my brain came up with o.o
I hope it turned out alright ^^
