They hang out. They watch TV for hours, curled and tangled up on the couch, JungKook tries to teach Taehyung to play cards and finally gives up when he just seems completely unable to understand even the simplest of rules.

Later, they stand on the high balcony where JungKook points out things that Taehyung has never even noticed despite flying over it all a million times, even before there was a city here.

JungKook opens Taehyung's eyes to the world in so many different ways.

They watch the sun sinking in the horizon and Taehyung realises he's never really paid any attention to it, always too busy completing his tasks and performing admirably, too busy trying so hard. And for what?

Despite their hidden and entirely opposing identities, the thing that is growing between them is sweet. A little bit tender, innocent even. Hardly something you would ever expect an Incubus to feel, let alone an Angel who has been created to feel nothing.

Yet in this in-between world, spurred on by human-like existence, Taehyung has been given the opportunity to feel and experience things that he could never experience as an Angel.

Here he can feel to his heart's content, to experience with senses he'll never have the chance to use again once he leaves this place.

And Taehyung feels a lot. Perhaps too much and too quickly but he can't help it -doesn't want to help it.

He wants it all.

Taehyung reaches his arm around JungKook's neck while they are still gazing at the setting sun as if neither of them have ever seen it before.

The kiss on the lips in gentle, like a feather, and long fingers touch a soft cheek in a tender stroke.

Something that JungKook doesn't ever remember happening before, happens.

His stomach flips and his heart aches. His dead, black heart booms at the gentle touch, at the affectionate, warm eyes... and it yearns.

Without a word, Taehyung grabs JungKook's hand and pulls him inside. He walks directly into the bedroom and stands himself in front of the bed, facing JungKook.

"Make love to me."

Taehyung whispers, his voice deep and warm but without an ounce of hesitation. The red on his cheeks is rich, his dark hair fluffy around his beautiful face.

The richly hued rays of the setting sun streaming through the bedroom window behind him create a halo where they touch the tips of his hair, as if lighting them on fire. They tint his golden skin with even warmer hues against the angelic white of his clothes.

It is in that moment JungKook decides he has never seen anyone more angelic than Taehyung, nor will he ever again.

So innocent and trusting -yet asking for such debauched things. The combination of the two is absolutely impossible to resist -which is just as well because there is nothing in this world nor any other that could make JungKook do anything other than what's requested of him.

The irony of the situation is not lost on JungKook.

The irony of Taehyung asking him to do the very thing he has come here to tempt him with. Asking JungKook to give him what he was going to push onto him just for a bet, a bit of light entertainment.

It no longer feels light -in fact, nothing about what's happening here feels light. In fact, somehow this feels almost... holy. Something so important that it should be sacred and despite everything that has already happened, everything that he wants to do and has done, and despite knowing that Taehyung wants it...suddenly JungKook hesitates.

Is this really the time to grow a conscience?

He wants to ask Taehyung if he's sure, he wants to tell him that he understands the importance of this and that he wants to treat it with the respect it deserves... but all he can do is to pretend that this is commonplace, mundane, something that they do every day -since they are supposed to be a married couple after all.

It's all so very far away from someone's first time. Not someone's -an angel's, first time.

It doesn't occur to JungKook that perhaps this is the moment that he should be honest about his identity.

Or perhaps it's too late for that now.

A hint of rejection ripples across Taehyung's face while he waits for a reaction from JungKook who is taking too long to respond.

While he is deep in thought, JungKook realises that the best way he can give Taehyung and what he is offering justice, is to do this and do it properly -like no one else ever could.

So when he finally responds, he just gazes at Taehyung, really looks at him, taking in the contours of his face, the shape of his eyes, the length of his eyelashes, wanting to imprint every single detail into his memory.

He cups the beautiful face in his hands and just silently cherishes what is right in front of him, having long since forgotten his pretend role as the husband or his stupid, gratuitous motive for being here.

Right now there is only Taehyung and JungKook and nothing else in the world exists.

"JungKook?" There is uncertainty in the small, quiet word and wanting to reassure him, JungKook leans over and brushes his lips against the Angel's.

"You are the most beautiful thing I've ever seen, Taehyung." He whispers, his voice breaking, helpless to stop the words tumbling out.

Taehyung inhales sharply, surprised by the tender words. His heart sings.

As much as Taehyung wants to dwell in the moment, he is painfully aware of how little time he has. He can no longer wait for another second to have what he has been dying to have -he now realises- since the very first moment he ever saw JungKook.

The intensity of the feelings is almost too much for him, they tighten his throat, sting his eyes and squeeze his heart. No words could ever describe the way he is feeling so he lets his body do the talking.

In an impatient, almost violent a gesture, Taehyung grabs the fabric of JungKook's t-shirt into his fists and yanks, pulling the man against his lips roughly, devouring him.

Immediately hard hands grab around Taehyung's waist, fingers digging into the soft flesh, bending him into the demanding embrace, arching his back, wielding him.

A hand runs up his back into the hair, lacing between the curls into a tight grip, the other slides down to harshly squeeze around a soft buttock.

Everything feels so good, Taehyung's eyes roll already although they are yet to really begin.

"M-More... I want more." Taehyung pants and JungKook, eager to oblige, practically throws him onto the bed, pulling his top off before crawling over toward Taehyung like a panther to its prey.

Taehyung feels that tension again, the unnameable, unseeable force that links them together, that makes their bodies move to the same rhythm. He doesn't understand it but for Taehyung it feels like their bodies are in charge now.

Taehyung's cheeks heat up under the intense stare, it touches him in a place that is somewhere so human that his angel cannot quite understand it, the feeling is so primal... so... animalistic, that it makes him wants to present himself to JungKook, like some desperate animal in heat.

Not allowing himself to think even one bit, Taehyung just goes with his body, following his unfamiliar human instincts. He rolls over onto his stomach and crawls up the bed, looking over his shoulder at the dark figure following right at his heels.

He can feel the heat of the black eyes spread along his skin and it burns, searing his heart until it beats like a hummingbird in his chest.

He lies down and without waiting for permission, Taehyung's hips rise and roll, gently wiggling the full ass to tempt the man climbing over him -who takes the hint, pushing his hard cock right against it, as if they were already naked, and grinds down.

The Angel offers himself to the Incubus...

JungKook can sense the rawness, the intensity of the moment in the air around him and it affects him, strongly. He feels himself sink a little deeper into his darkness, soak a little wetter in his lust until he feels the liquid fire smouldering, seeping into every corner of his being, setting his demon free.

He truly feels he prince of darkness that he is, the sum and total of the Incubus he was created to be and the blood in his veins courses on at the very thought of possessing the divine being underneath him. The need to own, burns.

A growl purrs at the back of his throat and he tries to rein in the aggressive side of his demon -completely ignoring the obviousness of why he is trying slow down and go gently.

Even if he doesn't want to admit it to himself, he has already become too attached to the delightful Angel and desperately wants him to be happy, to have a special first time.

He doesn't want his violence to taint nor harm him, JungKook wants to cherish him.

He wants to love him...

The shape on the bed is squirming, his desperate need so obvious from the way he grinds against the bed and whines, but JungKook wants to delay as much as possible, to build up tension to make the moment really count...to make it last.

Who knows if there'll ever be another chance for either of them.

JungKook shifts back down, running his hands all along Taehyung's curves, starting from the nape of the neck, over his shoulders, down the side of his ribs. He squeezes the slender waist, fingers slipping underneath the waistband to pull the off down on his way down.

He can't help the rich hum that rises from deep within him at the sight of the honeyed perfection that is Taehyung's ass. Taehyung whimpers, so needy.

"Please..." Taehyung's new favourite word, it seems.

Leaning down, JungKook takes a moment to kiss an ankle bone before nuzzling his way up between the slender legs, smelling the sweet scent of summer and honeysuckle as he goes. The Angel is so soft and warm that on his way up he can't help placing soft kisses on the insides of his calves, his thighs.

The closer he gets to the lush ass, the louder the pants underneath him get until there is a little desperate wail rising from the cushions where Taehyung's face is buried.

"Stop! Teasing! Please!" Taehyung cries just when JungKook mouth lands on his ass, where he kisses, nips and licks both cheeks gently before burying his face between the lobes to lick over the needy, twitching hole.

Taehyung screams, his ass lifting, pushing against JungKook's face, grinding against it.

JungKook merely grabs the rolling hips, shoving his face deeper into the groove, rolling his tongue thickly but leisurely.

"Ohohhhoh, JungKookie... please."

Despite his best efforts, JungKook is getting impatient so he moves up quickly and grinds his hard-as-rock, clothed cock right into Taehyung's ass groove in deep moves, his hot, harsh mouth clamping onto the back of Taehyung's slender neck, right where it meets the shoulder.

Taehyung moans, it's so loud.

Driven by a compulsive need to own the Angel, to claim him, JungKook's want darkens as does his need to hold him, restrain him.

Rocking against him through the layers, cock tight in the groove of the ass, JungKook rests on his elbow and worms his hand around to Taehyung's front -he grabs the Angel's throat, his jaw, and slips two fingers into the mouth before hissing rather harshly:

"Suck."

Taehyung moans some more because he feels JungKook's new roughness in his spine and he loves it, he wants more of it. He sobs, wondering if he can come just from this when spit starts dripping all over the fingers in his mouth and down his chin when he tries to speak.

"Pwease..."

JungKook knows what the Angel wants so he twists him to his side a little, leaning on a knee just to create enough space to get where Taehyung most wants him to touch.

He's soaking wet and boiling hot. The straining member is literally pulsing and twitching in JungKook's hands and it's enough for JungKook's cock to twitch and scream to be let out from the confines of his damp pants.

Taehyung feels so much, so, so much.

He is helpless under the torrent of emotions and physical stimuli: the weight of JungKook half on him, the lewd violation of his mouth and the mess because of it, the filth of the mess he knows he's making on the bed, the deep grind of the massive cock right over his hole -Taehyung can't even imagine what that will feel when it's skin on skin.

He can't fathom how something like that could even fit inside him but the thought of struggling to try is so hot that it alone has him moaning and begging for more.

Nimble fingers push the fabric of Taehyung's t-shirt up from the waist until they reach a nipple and without any warning whatsoever, there is a sharp pinch and Taehyung shrieks over the fingers in his mouth, his ass grinding against the cock so comfortably snug in his groove.

"Fuck, Tae... I'm going to have to shove my cock in you very soon if you're going to carry on like that..."

Just JungKook saying that has Taehyung moaning and he suddenly realises how much of sex is actually in the head and not just in the body. It's his thoughts and feelings, his wants, that make this even hotter than it already is.

The idea of helplessness, of willing helplessness, and the feelings it evokes twist Taehyung's insides with tension that is only added to with the realisation that JungKook wants to possess him just as much as he wants to be possessed.

Moving down from the nipple, the firm hand cups the curve of Taehyung's waist, then the hip and the noise that rises from JungKook's chest is deep, like a growl. A possessive growl and Taehyung basks in the sound of it.

Without any warning, there is a loud smack and a sharp sting on Taehyung's ass cheek. He yelps but can't ignore the throb on his cock from the heat that spreads all over from the impact on his buttock.

"Ahh..." Taehyung sobs, his body convulsing in pleasure, his cock twitching, leaking.

"You're so fucking... tasty, Angel." He whispers into Taehyung's ear, licking along the edge of it before he grabs a handful of ass, jiggling it lightly, as if to make a point.

By now, JungKook has all but forgotten about going gently or taking his time, only his lust guides him now -the only thing that he can hear are the moans and pleads of Taehyung underneath him.

Yet random thought drifts in his mind and JungKook realises that really, he's fucked because he's not going to want anyone else after this -how could JungKook ever want anyone after having had Taehyung?

Impossible.

He has a sense, a feeling that's partly made up of hope -maybe even wishful thinking- that this is mutual between them, that Taehyung feels the same, even when it seems silly to dream about that without considering his secret identity or the fact that they are an angel and a demon -the exact opposites of all creation and not meant to be together in any world, at any time.
