✧ HONGJOONG - MOUTH/LIPS ✧

Hongjoong isn't a big pda guy.

The most he does is rest his hand on your waist, hold your hand, or gently fix your hair. Words of affection or acts of service are big in your relationship, but kissing is absolutely a no-go.

Not in public, at least.

In the beginning of your relationship cute pecks on the lips were allowed, though Hongjoong would start acting more antsy and possessive after (you didn't notice as much as his friends would). Short kisses lasting less than a second he could handle -- or that's what he'd convince himself.

Beneath the surface, however, he was holding himself back. He was exerting a concerning amount of self-control over himself every time he tasted your sweet lips, willing himself to hold back from instantly melting against you.

His hands would squeeze into a fist as he'd watch you with dark eyes, going back to whatever you were doing, acting so unaffected -- as if you didn't leave him wanting for the rest of the day.

At the time, you could tell that he enjoyed the affection and attention (a bit too much), and you were more than happy to dish it out. But then one day, he started to shy away from your kisses, turning strategically so you'd kiss his cheek instead of his lips.

At first you thought it was because he wanted to keep your relationship private. He's never been the type of guy to flaunt you like an accessory, so it made sense why he acts so low-key about your love life when in public.

But then you started noticing how he'd act after you'd give him more than a peck.

---

A make-out between the two of you usually leads to sex.

Okay, scratch that, it always leads to sex.

It's like he can't help himself.

As soon as your tongue traces the seam of his lips, he's roughly pulling you against him. He overly indulges in tasting you, laving his tongue against yours as he moans wantonly into your mouth.

You thought he was just enthusiastic about sex, but it was something else that had him shivering against you.

So you began subtly experimenting with your boyfriend:

Tracing his lips with the soft pad of your finger as you feed him a juicy chocolate-covered strawberry (he'd look up at you with those adoring brown eyes as he obediently slurps up the sweet juices from your skin)

Playfully nibbling on his bottom lip to draw out a delicious growl from him (he couldn't hold himself back from grinding his hips against yours like a dog in heat, overwhelmed by the pleasurable pain)

Forcing him to suck on your fingers as you ride him roughly (you could feel the vibration of his broken groans as you pressed down on his silky tongue)

It became increasingly clear that Hongjoong's lips were a bit more sensitive than the average person. The real test was a kiss in public.

It was right after one of his concerts. You were so proud of your boyfriend that when he finally got off stage, you jumped in his arms and pressed your lips to his, eager to give him a deep kiss.

His hands, wrapped around your waist, tighten their hold on you as soon as your lips met his, pressing your body to be flush with his.

Barely a few seconds into the kiss, you feel it, pressing so eagerly against your stomach.

He's hard already, throbbing for attention under his tight pants as his slick tongue meets yours in desperation. His adrenaline from performing may be influencing his sudden boldness, but it's the kiss that was making him so hot and bothered.

"Mmph~" You try to break the kiss, worried that you were receiving stares from others, but he won't let you.

"Not yet, baby" He whispers hotly against your mouth.

"Hongjoong--!" You hit him playfully on the chest as you force him to separate from you. "Later." You grit out, handing him your jacket to use as a barrier between his obvious boner and everyone else.

Your face is heated with a blush as you turn to look around at the sly smirks that the others were sending you. It seems to sober him up a bit as he awkwardly coughs and starts a speech commending everyone for a great show.

So now you know -- Hongjoong's lips are for home.

✧ SAN - CHEST ✧

You were the one who sprouted a sudden obsession with his chest.

He's been working out a lot lately and he loves showing off, even if he doesn't admit it. He comes home in his tank tops or compression shirts with a shy smile, subtly flexing until you say something.

"Ooh, look at my boyfriend!" You tease, smiling as he saunters through the door. "He's so big and masculine~"

San laughs gently, shaking his head at your words (+ slightly fluffing his hair). He loves the way you dote on him, period -- small hands feeling over his biceps and showering him with compliments until he's pink in the face, begging with cute boba eyes for kisses and cuddles.

When you cuddle with him, naked -- or nearly there, your hands are like magnets to his chest. It's just so built and his skin is so hot and smooth, you can't help it!

San didn't get it at first, simply amused by the way you knead his skin like a cat. Sometimes you get particularly feral and start biting his biceps and shoulder -- another odd, yet endearing habit you've gathered recently.

He has started working out with longer-sleeved shirts because he's dotted with bite marks and bruises all over his upper body (with a few on his thighs and one on his cute butt).

You can't get enough of his body and he loves it.

But biting his chest -- that he wasn't expecting.

And he didn't expect that he'd like it so much either.

You were timid at first, placing soft kisses against his ribs and torso before gradually moving upwards.

He shivered as you brushed your lips against his right pec, his skin already buzzing from the lustful look you had in your eyes as you assessed his body.

You pressed gentle kisses over his skin, drinking in the soft sighs that fell from his pretty lips.

He gasped quietly when you gently licked over his nipple, flicking your soft tongue over and around his sensitive bud. Your eyes glanced up at him to see his reactions.

His pink lips were plump and shiny, bitten so deliciously from his attempts to ground himself, not used to this new sensation you were giving him. His flushed chest was rising rapidly under you, unwittingly pressing himself closer to your mouth.

He let out a whisper of a groan as you sucked his nipple in hot mouth, laving your slick tongue over him. A shock of pleasure traveled straight to his cock, making him achingly hard for release.

You squeaked as fingers were suddenly weaved into your hair, tugging slightly at the roots -- not pressing you closer or pulling you away.

You moved your mouth to the other pec, giving his other nipple attention. His hold on your hair became harsher the more you'd suck on him. And you loved it.

You moaned with him as you pulled him into your mouth, teeth just barely pressed against his skin.

"N-nghh~" He shivered, "Baby -- fuck -- p-please."

"What is it?" You swiped a finger over his hard nipple, finding the pleading look on his face to be unbearably adorable.

"I'm gonna bust if you keep going." He groaned softly as you pinched him teasingly, "Lemme get inside you."

"I don't know... I think I'd like to see you finish from this..."

✧ MINGI - NECK ✧

Mingi is a very sensitive boy, overall.

When your fingers intertwine with his, he can't help but squeeze your smaller hand in his, staring down your hands like he can barely believe that you're allowing him to touch you -- even as innocently as this.

When you press sweet kisses to his lips, teasingly and soft, he's instantly smiling against you from happy he is, pressing harder to deepen the kiss and eliminate the space between you.

When you drag your hand over his thighs, settling to your knees in front of him, he holds himself back from throwing you on the bed and fucking you into the mattress.

He's constantly overwhelmed with his affection for you.

Everything is intense for him.

But when your small fingers wrap around his neck, squeezing so gently as you pull him in for another kiss -- he almost makes a mess in his pants.

You sit above him, weight settling nicely over his lap, pinning him to the couch as you lick over his puffy lips.

Mingi whines against your lips as your grasp tightens around him, loving how his head grows hazy from the way you control his breathing.

His cock throbs under you as you start to pressing wet kisses on his chin, jaw...and his neck. Your slick tongue flicks over his heated skin, laving over fading marks that you've left over the past few days.

"Like it?" You whisper, staring up at his flushed face. He shudders as you drag the edge of your teeth against the crook of his neck, eagerly leaning into the feeling.

"You know it do..." He groans deeply as you suck his sensitive skin into your mouth. His large hands hold you by the waist, pressing your body down against his as he grind against your ass, making you feel how desperately hard he is for you.

You suck harder and his hips jolt against yours, stuttering deliciously as he mewls from the intensity.

"F-fuck -- wait --"

You don't. You go to that spot right under his ear, the one that makes him lose it, and suck another love bruise into his skin.

And it ruins him.

His back arches slightly as he throws his head back with a broken moan. You release his skin, licking your lips as you watch him shake under you, panting out heated breathes, coming down from his high.

"So sweet." You coo, comfortingly rubbing a hand on his chest as he starts to calm down.

"It's embarrassing..." Mingi whines. This isn't the first time this has happened.

You place a gentle kiss on the spot, pulling away when he starts to shudder again.

"I like it."
