A/N: I hate fade-to-black sex scenes. But thou must to post on FFnet without fear of bans.

This is the edited (read: massively censored) version of a smut-fic on Archive Of Our Own that I have to meet FFnet's loosely-if-at-all enforced guidelines r.e. adult content.

Thus, warnings: if the implication and vague description of two fictional characters having sex bothers you, don't read this. Strong adult themes present.

I've died and gone to heaven. Or maybe Kurumi's already eaten me and she's my angel. Shido's mind raced as he tried to process the bewitching sight in front of him.

Kurumi Tokisaki, the Worst Spirit, and strong candidate for the most beautiful Spirit, clad only in pure white lingerie, stood in front of him. Sensually, with grace beyond her years, Kurumi had loosened her skirt and blouse, which lay discarded at her feet as she revealed herself to him.

Until now, Shido would have never thought that pure white lingerie, exotic yet not intentionally erotic, could match up to the lacy, revealing black sets from the magazines that Tonomachi had tried to show him – or more fittingly, the set of lingerie that Kurumi's clone had worn at his request. Yet somehow, Kurumi, with a light blush and a coy smile, managed to turn the white, innocent panties and matching bra into a devastating weapon of temptation surpassing Origami, Nia and Miku's botched attempt at seduction even with purposely designed lingerie.

"Shido-san…I gave you a promise," Kurumi said as she began to move towards a spellbound Shido, her hips swaying seductively.

…a promise, to give you my everything, except my reiryoku…

Kurumi's words echoed through his mind as she stepped closer. She was like a siren – her sweet voice, her honeyed words, the way she moved with all the grace and predatory intent of a panther – all of it rooted him to the spot, unable to move or look away as if his whole world was reduced to and centred on Kurumi.

Why couldn't he move? It wasn't as if he hadn't seen the other Spirits in a similar state of undress before, or act with similarly amorous intentions. And hadn't they tried to build up his resistance, aging themselves to try and seduce him? And as exciting as that was, he had been able to resist – albeit just barely. So what was it about Kurumi then, which made it so hard for him to turn away?

Maybe it was her teasing, seductive personality that few of the Spirits could hope to match. Maybe it was the tantalising aura of mystery around her. And maybe it was that little beat in his heart that glowed and sped up when he had to match wits with Kurumi, and that became even more prominent as Kurumi reached him.

Slowly, almost lovingly, Kurumi wrapped her arms behind his neck. Literally at arms-length, Kurumi met his eyes with her red and golden ones.

"H-hey, Kurumi…" Shido tried to break the tension hanging in the air. He made the mistake of breaking away from her gaze and looking down.

The sight of her milky white cleavage, soft, silky smooth and looking oh-so-inviting snatched what little breath he still had away. His mouth went dry and his heart thumped faster than ever as he imagined, quite vividly, exactly what Kurumi was promising him.

With great difficulty, he forced his eyes to look at Kurumi and not her generous chest.

A small part of him however wanted nothing more than to tear off her remaining clothing and bury himself in her breasts.

Kurumi took a step forward, the same coy smile still on her face. The sudden intrusion into his space caused Shido to take a step back.

Kurumi stepped forward again.

"K-Kurumi, wh-what are you doing..?" Shido desperately asked, his arms locked ramrod straight at his sides – afraid that if he touched her in her current state, he'd lose all control and turn into a raging monster the likes of which would make his feverish disaster a few months ago look tame – as he gave ground to Kurumi's unrelenting advance.

Kurumi's only response was to continue moving closer and closer.

Shido couldn't help but to feel slightly unnerved at the situation; yet he couldn't prevent a tremor of excitement that raced through him, sending the hairs on his arms standing on edge. He swallowed nervously. "Kurumi –"

He yelped suddenly in surprise as his leg struck the bed, tipping him backwards onto it. Quick as a flash, Kurumi suddenly dropped into his lap and straddled him, pinning him down and preventing him from escaping. The excitement and nervousness shot up tenfold, not helped by the fact that he was very conscious that her panty-clad crotch was directly above his – the mere thought of her womanhood grinding into him was causing him to harden in response.

"Shido-san," Kurumi said, her voice low and husky, eyes half-lidded as she licked her lips. He found himself drawn to the sudden motion, fixated on her mouth and the wetness on her lips, and suddenly wanted nothing more than to kiss her, to snatch her soft lips between his own and taste her.

Kurumi kept speaking however, drawing his gaze away from her lips to meet her heterochromatic gaze.

"I did promise you," Kurumi said, placing her hands on his shoulders.

Slowly, Kurumi traced her hands down Shido's shoulders and arms, leaving behind an electrifying tingle that sent shivers racing down his spine.

"And I always keep my promises, Shido-san." Kurumi suddenly pulled his hands to her almost-bare shoulders before reaching behind her and undoing the clasp of her bra.

"Hey, Kurumi!" Shido panicked as he felt her smooth skin under his fingers. "Wait –!"

Kurumi did not wait as she took hold of his hands again, and guided his fingers underneath the straps of her bra and pulled them down. He held his breath as her bra fell away, revealing Kurumi in all her near-naked glory, the sight causing him to momentarily forget how to breathe.

Kurumi was beautiful.

Kurumi's long, pitch-black hair fell over her shoulders, contrasting brilliantly against her porcelain-white skin. Her bangs, which usually served to cover her golden eye, a reminder of her supernatural nature, had parted to reveal hints of the eye underneath, a stark contrast to her other blood-red eye. He couldn't help but stare and admire the rest of her body, willing himself to burn it into memory. Kurumi was the perfect embodiment of the feminine form; from her beautiful face, down to her slender waist that begged to be held, and flaring out to her hips that her panties still hugged.

But it was her breasts which drew most of his attention. Kurumi's Astral Dress emphasised her well-endowed body, and she enjoyed taking advantage of it to tease him, giving him glimpses into her cleavage, purposefully bending down to look at him in their previous interactions. Now that her breasts were free from her dress or any bra, they were more than he could've imagined – and it took all of Shido's willpower to resist reaching up and grabbing them.

Then Kurumi gently took hold of his hands, bringing them tantalisingly close to her chest – so close, he could almost feel the warmth radiating off Kurumi's body.

Shido's willpower wavered.

"Touch me, Shido-san," Kurumi whispered seductively, hints of lust colouring her tone.

His willpower promptly shattered.

A grin spread across Kurumi's face as he reached for her, and she let out a sigh of pleasure and arched her back as the boy's fingers started running across her flesh…

Kurumi took the lead that night. The beautiful Spirit, who had promised him everything, carefully coaxed and guided Shido through his first intimate experience with a woman. For Shido, who had dreamt of the moment, it had more than he could've imagined in his wildest dreams – or more appropriately, given that it was Kurumi who was sitting atop of him, a beautiful nightmare.

Yet during the night, no matter how close to him Kurumi became, her mismatched eyes staring hungrily into his own as her hips rocked him against her, she never, ever approached his lips with her own.

And through the haze of desire, lust and pleasure that clouded both of them as they coupled, Shido did his best to remember every minute detail of the moment. It was a fruitless endeavour, as only snatches of it would likely remain – the sensuous moans that escaped Kurumi's lips, her breasts bouncing and swaying, the way her mouth parted slightly as she panted and licked her lips, lidded eyes clouded with lust gazing back at him.

But there would be few memories more precious than when Kurumi reached her second, screaming climax of the night after his. Quivering from the sheer pleasure, Kurumi could do nothing more than hold onto Shido tightly until her climax finally ended. Completely exhausted yet satisfied, the Spirit collapsed bodily against his chest, falling back onto the bed in each other's embrace, panting as they tried to recuperate from the intensity of their coupling.

Shido groaned as he slipped out of Kurumi, shivering at the sudden cold and friction. He still hugged Kurumi against him, listening as she panted and shook from the little aftershocks of pleasure still running through her body. Still amazed at what they had just done and what he had experienced – including the loss of his virginity – he summoned the strength to speak, a normally everyday action rendered all the more Herculean with the complete lack of energy he felt.

"That," he stopped as his voice broke, and he swallowed and started again. "Kurumi, that was amazing. Thank you."

He felt connected to Kurumi in every way possible, emotionally, mentally and physically, and he poured out his heartfelt thanks to her for sharing such a special moment with him. The exhaustion that permeated him from their frenzied lovemaking couldn't prevent a deep sense of satisfaction as he held Kurumi against his chest, nor could it prevent the happy smile that settled on his face. Truly there was no other comparable experience for Shido. He could die, quite happily, now. The world was complete, and it consisted only of him and the beautiful, exhausted Spirit in his arms.

Kurumi finally shifted, letting out a pleased sigh as she lifted her head and met his gaze, head tilted in a flirtatious manner. "To hear such thanks from you Shido-san, and after making me come quite a few times tonight as well…you really know how to please a girl," Kurumi smiled as she rested her head against his chest. "I'm glad you enjoyed it, Shido-san."

No more words were said. Shido began to caress Kurumi's hair, gently tracing through her silky black locks as they settled into each other, basking in the warm afterglow. The warmth didn't last, as the chilliness in the air eventually forced them into the covers, shuffling around with Kurumi pulling the blanket over them.

"Hey, Kurumi?"

"Mmm?" Kurumi let out a sleepy acknowledgement for him to continue.

Hugging Kurumi to his chest, feeling her warm body press snugly into his as if they had been made for each other, it was difficult for Shido to reconcile the Kurumi he thought he knew half a day ago, with the Kurumi now who had shared everything with him, who showed tantalising hints of vulnerability and humanity of the girl underneath. Even though he knew her goal and title as she proclaimed it, and that normally being close to and alone with someone who had admitted to wanting to eat him would rank quite highly as a stupid idea, he felt safe and protective of the girl in his arms. For that, he had to ask her.

"What happens to us now? Does this change anything? Are we – ?"

Kurumi hushed him with a finger to his lips.

"Sssh. Not now," Kurumi said tiredly, not moving from her position on his chest. "Please, can we just enjoy this for tonight? Tomorrow, I will tell Shido-san everything. I promise."

Shido guessed that there had to be some reason Kurumi didn't want to address the issue tonight. Relaxing at the fact that she wasn't planning to leave, he nodded. It wasn't a hard choice really – he was tired and wanted nothing more than to sleep now. Kurumi's breathing had slowed too, becoming rhythmic as she began to slumber. Shido could feel his eyelids drooping as Kurumi's warm and comforting presence also began to draw him towards sleep.

Tomorrow. Kurumi had promised that tomorrow, they would find out what they were. As much as he wanted to know what their relationship would be now, Shido was okay with waiting. He wasn't worried.

He knew Kurumi always kept her promise.
