A/N: Please note that this story will contain very mature content, as well as the element of incest, specifically Jack harboring incestuous feelings towards Adam. If you are in any way, shape or form uncomfortable with any of these ideas, then you should not read this. This chapter does contain mature content, including incest + homosexual feelings, and masturbation.

They had been doing something completely mundane earlier—either playing video games or watching some random movie that was playing on cable channel, he can't recall—just typical, teenaged behavior.

Normal. Acceptable.

It wasn't until Adam announced that they should probably get some sleep before they turned into complete zombies that he agreed to turn off the screen and follow his brother up the stairs.

Two rooms. Two beds. Two brothers.

Twins.

So why is it now that he is currently perched precariously above his twin, who is sound asleep with a look of pure serenity on his face while he has one hand sunk inside his boxers, stroking himself harder and harder as his gut churns with a mixture of shame and pure ecstasy?

This isn't normal; he knows this, understands that normal siblings do not have lustful thoughts about each other, and certainly do not jerk themselves off to the other while said other is sleeping right below them. But oh…he cannot help himself. The perfection that is his other half…no, he'd once read an article written by some other twin in which the author described twins as being the perfect definition of a soulmate, one who perfectly understood you and literally made up half of your own being. He thinks of making Adam all his, only his and a low whine escapes his tightly clenched teeth, much to his dismay.

'Shit! Don't wake up, don't wake up, please don't…'

Below, his twin stirs for a brief second but doesn't open his eyes. He heaves a sigh of relief, wondering if he should retreat now while he still has the chance. For if Adam were to wake right now, just the thought of his reaction to this…this sickening behavior… His hand continues anyway, pumping a little harder, a little faster—maybe if he can come before things get any riskier…

"Hmnn…shut up Jack…" The body below turns and for a second he narrowly dodges hitting his legs which are straddled just above his brother's waist, and in that twisting movement the shirt is pulled up, exposing the paleness of his body. With the moon streaming through a crack in the curtains, he is spellbound by this sight, of what he claims is utter perfection: the vast expanse of pale skin, alabaster-white and entirely smooth, unlike him, whose torso is littered with scars from the countless fights he's gotten himself into over the years. The muscles lying below forming perfectly etched ridges…he just wants to reach down and run a fingertip, just one, down the lines and down, down down…

'Oh, you said my name…' But not like that, not like the way he wishes, all panting and desperate; no doubt he's simply dreaming about having yet another argument with him, always being exasperated with him about one thing or another.

No, his brother surely would never harbor such repulsive thoughts, such impure thoughts. He has always been the better of the two—maybe because he's just a few minutes older?—the responsible one, mature one, always looking out for him and their mother while he became the literal wild child, running around and causing all kinds of mischief one way or another. And still he is always forgiven, always; no matter how bad things got between them, always…

'But will you forgive this? This sin…of lusting after your own twin…'

He's breathing much heavier now, trying to pant silently because if he were to remove his supporting hand now, he'd fall over for sure; but it's hard, hard to not just moan and call for his brother, to beg for his forgiveness. 'I'm sorry! I know I'm not normal, that I'm some sort of freak; you can hate me, call me a monster, a sin—that's okay with me. Just please, don't push me away…don't reject me…'

Something slippery is trickling out the tip and he knows he's close, he's very close to climaxing…and yet, through the haze of lustful indecencies, a piercing voice shuns him, shaming him for being able to come to the thought of his own brother and his desires drop a little, not completely but just enough so that he doesn't come quite yet.

'N-no…ugghnn, god, why can't I…come…!'

Perhaps he truly doesn't desire his brother after all, and this is just some momentary madness, some misfiring of neurons combined with the unpredictability of a teenager's hormones. But that doesn't make him any less hard, his hand move any less faster or tighter as he feeds the growing heat in his lower gut. He swallows hard lest he accidentally drools all over Adam (which would wake him up for sure), mouth dry and lungs heaving for air from the silence he is forcing upon himself.

Or maybe this is just some extreme form of narcissism, of self-love? True enough, they are identical down to every last physical feature, including their unusual silver hair and piercing emeralds for eyes. But that doesn't explain why he never fantasizes about himself, clearly making a distinction between the two halves 'Jack' and 'Adam'.

'Adam is better, he's always been the perfect one…whereas I'm just a disgusting, worthless piece of trash…'

He doesn't remember when this started; for as long as he can remember, they've been brothers, twins, just like any other siblings. Sure they fought and argued, and competed and occasionally made each others' lives hell, but it had always been bonded with sibling love. Their desire to protect each other.

So where down the path did this sibling love turn into illicit desire?

He thinks maybe it was there all along, just dormant under the conventions of brotherly love and social expectations, of childhood innocence. But now that they're older, and more importantly, the introduction of that other set of twins into both their lives…

The Ogura twins. Identical twin sisters, just like them, one shy and gentle while the other was a whirling blaze of sass and attitude. He'd been taken with the brash one—Nobunaga or rather, Nobunagun as she'd dubbed herself—immediately, her fire and spirit unlike any other girl he'd met before. And no matter how many times Adam had denied it, he couldn't lie to his own twin about his burgeoning feelings for the quieter one, Sio.

Twins dating twins. Everything was fine and dandy, right? Oh, if only all things in the world could be so simple…

He wants Adam to be happy; truly he does, for nothing is more important than his brother. Even if it means acknowledging that one day, they will part, and lead separate lives…his breath catches as his nail scratches the sensitive head and a deep wave of pleasure erupts, so powerful it nearly knocks him over and brings him face-to-face with his twin, so close he can count each individual eyelash and smell the scent that is purely 'Adam'.

How bad would it be if he just leaned down right now, and kissed him…but no, he still has some level of self-control, what little is left. 'No touching, only looking…' Every time he is about to orgasm some guilty self-conscious barges in, reminds him again and again of how wrong this behavior is. Yet…at this point, he is all but lost to his own pleasure, is desperate to take everything he can get at this point—Adam's breath fanning against his face, how beautiful his other self is just lying there—a sudden tightening in his stomach and he knows it's coming—

'—oh god Adam, I'm coming because of you…I'm so—I'm sorry—Adam AdamAdam—!'

"Adam!"

Unable to hold anything back, he lets out a cry and to his horror, the force of his orgasm not only causes him to actually call out his brother's name, but his arm weakens and he collapses face-first onto the other's body, instantly waking him up.

"Ugh what th—Jack?!" His brother immediately sits up while he hastily pulls his hand from his underwear, hoping he won't notice the stickiness. "Christ, yeh scared the shit outta me…shit, you all right?" He peers worriedly at his twin, taking in his appearance—chest heaving, clothes all sweaty and hair sticking to his forehead and—were those tears? "Oy, what's wrong?"

"I-I-I, uh, I…" He wishes he can form coherent sentences, but he can barely catch his breath, the adrenaline from both his climax and fear still coursing strongly through his veins. "S-Sorry, I…had a…nightmare…" The lamest of lame excuses, but in the state he's in now, it's all he can think of.

"Jesus, must've been some nightmare. Here, need a tissue?" He blinks as it's offered to him, for a second scared that his brother might've guessed the real reason, until he gently presses it against his cheek. "Yer cryin'…"

"Oh…" When did that happen? It isn't just a drop or two either, he realizes as he wipes his face, but enough to have left two sets of tracks. "Thanks…"

His brother sighs and pats his shoulder. "Sure. So uh, yeh wanna…talk about it?"

"Huh?" He blinks stupidly.

A silver brow raised in slight irritation. "Uh, th' nightmare? That is why you apparently fell over me, and are now in my bed, correct?"

"Oh, that…it's, uh…" He can't meet his brother's eye, because one look and Adam will know instantly he's lying. "It was…weird. I-I mean, just…" Shit, if there was one thing that being twins made difficult, it was lying to the other. Still, there was no way he could ever reveal his forbidden thoughts towards his brother.

"Fine, 'f yeh don't feel like talkin' about it, then don't force it. Though, I gotta say, you haven't come running to me about a bad dream since we were what, ten?" A hint of teasing in the elder one's voice, completely oblivious to the actual reason for his being here. "Was it really that bad?"

"I-I—it's none of yer business! So what if it was…" Cheeks burning, he huffs angrily and wipes his eyes, suddenly relieved that things are back to 'normal'. Normal siblings teasing each other…the way it's supposed to be, right?

Adam just laughs at his childish fit. "Riiight. Anyway, yeh sure yer okay?"

"Yeah…don't worry about me, I'm…okay now." He nods slowly, as if to reassure himself that yes, that was just a fit of momentary indulgence. Adam is his twin brother, nothing more.

At least, that's what he tells himself until Adam reaches over, and pulls him close, looking at him straight in the eye.

"Hey, listen Jack…I know yeh hate 'brotherly love' an' all that shit, but I'm serious—you can talk to me about anything, yeh know that…right?" His face is so close that it brings a wave of heat running back up but he tamps down that feeling and swallows nervously.

"I know I know, god, don't hafta get all 'mushy' on me…" He pulls away, afraid that lingering even a second longer and he will lose control entirely. "Ow!" A hit in the back of his head with a pillow and he turns around, glaring at the perpetrator.

"Hn, well looks like someone's back to normal…anyway, I'm goin' back to sleep, unless yeh needed anything else?"

'Yes, I need you…'

"…No. Sorry for…bargin' in like that." Never again; he can't risk this again, not when he still loves his brother as a brother. Why he even did this in the first place…for some reason, he can't think of the answer now, after it's all over.

"…Ookaay." A pause. "Um. Jack."

"…Yeh?"

"…There a reason you're still here?" Too late, he realizes that he's been caught up in his own volatile thoughts for the past minute, instead of 'acting normal' and heading back to his own room.

Maybe…just, one last thing…

"…Can I…stay here?"

His twin stares at him hard for a second, and instantly he regrets his decision—how stupid, they're nearly grown men at this point, and still he wants to share a bed like they did back in primary school? How foolish.

"…Uh, sure…I guess…" The tone clearly states that he knows there's something else, or at the very least, there's something in that dream that greatly shook him. But as always, he is the kinder one, the mature one, and so he allows him to stay without any further questions. "Dunno if it'll be that comfortable though…"

Now he feels like shit, in more ways than one. But it's too late to back out now; if he changes his mind again, that would only raise more suspicions and besides, he really does want to stay by his side tonight. "…Thanks." He hesitates, before slowly lying down, filling half of the warm crevice after Adam scoots to the side to make room, his back pressed against the other but instead of cramped it feels comforting. The pillow and sheets smell like him, and it fills him with this strange sort of coziness, of memories back when they were younger, memories that he'd nearly forgotten.

"G'night, Jack…"

"'Night, Adam…" In less than a minute he hears his twin's breathing even out, indicating that he's already asleep again. Slowly he sits up, his brain yelling at him to lie back down and get to sleep already, but just a little bit—

—his lips ghost the other's cheek and it's just as soft and smooth as he imagines—

"—I love you, Adam."

Somehow, he doesn't care if his brother actually hears it or not. It's best if he doesn't, if he never knows—but he can't help but hope. For even as he finally starts getting drowsy, and at last his thoughts turn away from the body that is lying right next to him and instead to that of a lithe, petite shell of a spitfire who can match even his acerbic tongue—

—he knows at this point, there is no denying it—that he is in love with his twin brother.

Truly, madly, deeply in love.
