This story, however, belongs to me.

My friends all seemed to like this for some reason even though I'd honestly planned on keeping this... "a hidden gem". Anyway, sorry for the strangeness of this.

-Let's Take The Final Step-

A warm hand curiously slides along the front of his pants, gripping as if to size him up, and air hisses past his lips, his hips jerking forward without hesitation in response. Blue eyes, calm, narrow and brimmed with desire peers at him as her hand trails along him once more pulling out a similar reaction. He watches her, heat gathering at the back of his neck causing his mind to waver from its usual strict paths to more jagged, instinct driven ones, as her lips full and colored a soft pink begin to curve up just the slightest revealing a hint of two sharp teeth over her bottom lip. He attempts to muffle a groan as her next grip grants him a promise of future relief.

"Zeldris, can I see? How big it is? I've heard they can be big, but I'm not sure in what way." Her soft voice, something he always decided was like a delightful purr in his ears now causes embarrassment to flare in his cheeks melting straight down his neck.

Zeldris looks away from her intent stare, his eyes dark and hazy from her continued touch decides to stay on the blouse she once wore now discarded on to the bed. "Um," a cough or a choke overcomes him and instead he simply nods. Vibrations travel wondrously along his problem trapped in the confines of his pants when her fingers begin the tricky process of undoing the fastenings and his eyes can't help but be drawn back to her, to the vampire that's held his attention for so long.

She appears to have no outward problem with working him free, her hands carefully pressing against his hips, searing like flames against his exposed skin as his jacket was lost somewhere along the way as well when they got it in their minds that tonight would be the tonight. No more waiting. No longer holding back. And he watches her, Gelda, as she perches forward, chest bare with a few bruising bite marks from when he got a bit excited, hair a bit messy from its usual neat order and feels his pulse run all throughout him like a cry for more that builds and builds until he physically can't take the pain–

She gasps, knocking him from the whirlpool of need he was falling into and alerting him to the flash of cool air burning against his arousal now curved proudly into the air.

His eyes practically fling to her face gauging her reaction for any signs of disapproval, already weaving out a million and one explanations for this or that when her voice flows out, "It's.. Wow… And it looks so… angry, like you." Her eyes meet his again, this time darker, filled with flecks of flirty mischief and Zeldris swallows thickly at the same time finding his chest rising much faster at her clear approval.

She doesn't stop there.

Gelda tentatively wraps a hand around him and he feels the smooth texture of the palm of her hand like a sensation that pegs from his neck all the way down low in his stomach making his jaw go slack. Then she leans forward a lock of her hair falling in front of her face as she coos in a silky tone, her eyes only on what she holds captive in her hand, "What's the matter? Do you wish to cut through me, too?"

His head tilts back as he imagines it, his length sliding effortlessly into her aided by the slickness of her need he helped her produce just like his blade sometimes does to others, covered in the blood of countless souls. Zeldris' hips roll without thought and his throat grates out, "Fuck, you have no idea."

His ears pick up the sound of her chuckle light and smooth. The demon shivers.

The mortifying sound he makes next is something he's less willing to let himself live down when her lips, wonderful and addicting, suction around his tip and begin sucking with an expertise known to her kind. The core of his bones sing with ecstasy and he fights with a strength he's been building for years to not fall into and press deeper into the blessing that is her mouth. "G-Gelda… S-Stop."

It takes a moment that feels like an eternity and her tongue drags up the the tip in a way that pulls a little satisfied noise from his throat, but she does listen to his protest. Her eyes are sharp, weighing on him with the years she has over him, just from the way she gazes up at him from beneath her lashes. And he feels his hearts leap past their rhythm, still astonished that she found someone as young as he to her liking. Still though she pouts, her face tantalizingly close to his twitching length, "Why did you stop me? I know I can put it in my mouth and we're going to find a way to get it in me too soon. Is that what you're worried about?"

Did she have to bring that up? She must notice it too, the way clear fluid begins to bead at his head and sluggishly slide down his length. Fuck, he needs to show restraint, control. But the prospect is too good to imagine. His eyes swivel away only to find the flush of her chest, the swell of her thighs and the v-shape in between them, and his words come out a flustered rush. "You shouldn't do that. You're a Princess."

"And you're a Prince," she counters smoothly, forcing him to focus on her entirely when she pushes into his lap the next moment.

He sucks in a breath, startled when his hands find and grasp the heated cushions of her bottom, holding her in place. Her hands cup his cheeks before her fingers dance around his ears and dig into his hair. Zeldris doesn't think he can find words as he looks into her eyes burning like liquid blue flames into his. "If you want to try that stuff later, that's okay… I'm more than ready to see what it feels like to have you inside of me now, Zeldris."

His stomach pinches with nerves and anticipation so hard all he can do is nod and lean them forward into the bed beneath them. He wants to do this right. He has to. This'll be their first time and he wants her to remember it with a dreamy smile on her face, but… not for the first time his nerves begin to fester and sit beneath his outward edge of calm just waiting to screw him over like with their first kiss…

He blinks down at her, her expression full of encouragement, belief, and the undercurrents of need and he decides: Bring her pleasure.

Her breasts come beneath his palms as his lips find her neck, his tongue tasting her skin, and his teeth nibbling her flesh and she sighs, slow, long, and beautiful and his chest begins to loosen. She moves under him, her legs shifting around his waist and her chest pressing up into his hands and a another sound builds within her fueling his urge to satisfy. Zeldris grips the swells of her chest, massaging there as he remembers how they felt under his tongue and the flavor her nipples bore… His fingers pinch the perked nubs, rolling his thumb over them just as she arches, pressing the hot slick of her core against him with a soft cry causing his fingers to tighten reflexively.

She cries out for a different reason.

The sound jolts him from the rhythm he was settling into as he pulls back, letting go.

"Just a little too tight." She informs him with a patient smile that does nothing to diminish the flush of humiliation in his face.

"Uh… Sorry." Something urges him to draw back, but she wraps her arms around him, keeping him right in place.

She kisses him, quickly with a little laugh that draws her lips up and it becomes easier for him to relax against her. "Don't worry. I don't know much about this either… Just keep going."

Her lips soft, caring, and at the corner of his mouth are all he needs to brush off his folly and hope he doesn't make another. His hands move fully from the offended area and settle then on her hips, feeling the round curves with a notable spark that bounces beneath his fingertips. She's always been so smooth, so unblemished, like a treasure tucked away, meant to be hidden from him.

Gelda's fingers clench into his back and her rushed breathing sounds right next to his ear. "Yes, l-like that…. Don't stop."

And he doesn't halt the natural way his hips find a home between her legs or the way he ruts against the wet heat he finds there. His mind whirls at how slick she is as he glides against her smooth flesh, taking slow, deep breaths so as to not get overwhelmed too soon, and marvels at the fact that she's getting wetter still. Her body's twitching under him as her nails scratch along his back and she opens her legs wider as she whimpers as if begging him to make the final move.

Zeldris' hands spasm on her hips as he pauses. She wants this, they want this, so why prolong it? His lips find her cheek, then his nose settles against the side of her hair. And with his next breath he shakily aligns his hips and presses onward.

The sheer magnitude of pleasure that begins to consume him with each inch she takes is immeasurable, so much so that he feels the muscles throughout his body thrum. He just wants to sink into her, bury himself until he can't see straight and his mind's too blown to think past going deeper, harder… He goes by strict rules near constantly. This is his only chance to–

Gelda makes a tiny pained hum it's like a douse if water splashes over him. He sucks in a breath, barely able to keep himself from falling prey to his need. It only takes one look, but it's enough to see that she isn't enjoying things as much as he. His mouth forms a dismayed grimace. "I'm not doing this right am I?"

He starts to pull away, but her legs curl around his waist keeping him there. Her eyes are firm even if pained as she tells him evenly, "Women wouldn't do this if it didn't feel good at some point. Besides, I can take a bit of pain."

He knows she doesn't mean physical pain. All the same it causes a twinge to work its way throughout his chest. He doesn't move further.

Her hand moves to curl under his chin and their eyes clash. "Just go slower. Rock into me… I want to feel all of you, Zeldris… Will you grant me that?"

Suddenly much hotter and stiffer than before as he groans and gives her a hooded gaze, he responds in an equally low tone, "I'll give you anything you need…"

Her advice is fruitful, allowing him to inch into her bit by bit with the guidance of her sighs and shaky moans until finally, his hips rest against the back of her thighs and their mouths can't seem to break apart for more than a few moments. Blood pounds in his skull like the beat of their passion, making it hard for him to think properly as his hips move back and forth again and again like little slices of heaven. Her fingers on his sides, his back, his chest feel like drops of molten that burn straight to his groin and he groans breathless finding it hard to slip from out of her for too long. Her teeth nibble along his neck and that molten begins to rise in him rapidly, raising sweat along his skin and making his thrusts shakier.

She moans high and long stealing the breath from his lungs as he sees her cool mask crumble into one of desperation with each jostle his thrusts causes her body to make on the bed. Noticing his slack jawed stare she gains a slight smile even as her head rears back into the bed with the next slap of his hips. "I knew you'd… Ahh, you'd fit."

Despite the slippery feel of control that quickly begins to sear inside of him, he laughs, breathless with her bringing his face closer to hers so that their noses brush with the motion of the bodies. Fuck, it feels good, being with her after so long of imagining what it would be like. She's so hot as he pumps into her, so strong as she grips every inch of him. It's… It's like they were meant to press together this way, her beasts smooshed and bouncing between them, she was meant to open up to him, her legs around him like embers slowly burning away his senses as the wet sloppy noises made between them heightens the bliss in him until he–

The pleasure he was relishing in abruptly becomes his enemy.

Zeldris' body trembles as he attempts to slow his thrusts realizing just how little stamina he has, already feeling it at the base of his skull, the shaky feeling just before a feeling so magnificent he'll be relaxed for days. But Gelda. He needs to do this for her. Already she's lost in the rising peaks of pleasure his rather unskilled motions bring her. Her eyes are dazed yet fixed on him like he's an addiction she can't lose, and her lips leave feather light touches wherever she can reach, wearing at his resistance, but he tries. His hands grip her hips urgently even as he begins to slip over the edge with harsh breaths, "Gelda, I-I can't… I–"

'Damn it, damnitdamnit! Think of something else anything else!' But it's damn near futile with the sounds she makes in his ears and the way her body holds tight around him. The coil unravels in him with a snap and fuck it feels good, so fucking good, as he buries his noses into her sweat moistened neck and drills onto her, his vision blurring with the force of his release into her depths. And from the feel of it, she doesn't hold it against him, clinging to him until he begins to slow to a winded stop.

When it's all said and done, Zeldris doesn't grant himself the pleasure relief grants him as bitter self loathing brims within him. This was their first time and he screwed up, proving himself once again to be the failure of a third son to the demon king. 'How could I disappoint her…?'

Gelda shifts under him and it just makes him want to slink away shamed, until her fingers twirl in the back of his hair in a familiar loving fashion. "That actually felt really good, Zeldris, really good… Don't think of this as a failure, think of it as a chance to work on your mouth skills next," His breath hitches at the feel of her teeth, two sharp fangs in particular, scraping against his neck, "You're all about perfecting your skills aren't you? You're going to fill me up again later, don't worry…"

"…Fuck." He's definitely going to perfect his skills. And by then he's going to have her melting in the palm of his hands to his each and every whim.

~.~.~

"How could this still be so good after so many years?"

They had wound up tangled together at the head of the bed after their… was it third round of sex? He presses his knuckles gently against her shoulder blade as she rests against his chest, holding her close. Zeldris merely listens to the sound of her voice as she speaks, memorizing the tones for the umpteenth time as her delicate fingers trace patterns into his chest, a map only she knows. "I mean, you make us so dirty and I'm always too tired afterwards to get cleaned up right after. It's so gross waking up like this, Zeldris. Why do I let you do this to me again?"

A chuckle comes to him deep and pleased as he breathes in her scent, his nose against her hair. "I can clean you, if you want?" He begins to untangle from around her, sliding down her body with a mischievous glint in his eyes.

Her mouth opens wide and her cheeks flush before she can form a word. He loves it. "Oh, no you don't! That will only lead to trouble!"

He laughs again, a sound he only lets her hear, and moves back to his place beside her, becoming her pillow once more. "You were the one who brought it up. Besides you can't get enough of me. The reason why it's still so good is because I always give you such mind blowing orgasms." He brings her hand from his chest to his lips and kisses her fingers to hide his prideful smirk.

Only she doesn't seem to take much notice of it as she slips her hand from out of his and instead brushes his bangs out of his face. Her blue eyes gain a soft edge as she peers at him, curling her fingers in his hair as a lock of her own falls in front of her eyes. "You didn't that first time…"

Something inside of him tightens significantly and his face scrunches in a grimace in remembrance.

But she looks so fond, her eyes bright and her smile warm. "You may not have finished me off in the usual way and it may have hurt to begin with, but it felt good after a while and… there's really nothing that can compare to being with you that first time." She gives a dreamy sigh. And as her head moves to rest on his shoulder, her eyes shut with her content smile.

Zeldris has never felt more in love in his life as he watches his wife with tender eyes in that moment, his throat tight with emotion. It's ridiculous how he'd wished for her to think back on that moment so long ago in fond remembrance and somehow she has. She does. This woman makes him light when the world has turned him into a cruel, bloodthirsty, murderer. She's stuck with him through it all. Through all the blood and loss, she still wants to be with him. She chose to become his wife. And she finds it in her heart to love him.

Zeldris sneaks in a slow, lingering kiss that lifts her eyelids revealing sleepy blue orbs. His forehead rests against hers and he murmurs lowly, "I love you, Gelda."

She sighs and nods, her fingers gently brushing against his cheek. "I know… I love you, too."
