Work Text:

He was carrying her, bridal style, through the labyrinth-like castle hallways after returning from another of their weekly dates. Their lips were already locked in a scorching kiss, all tongues and teeth as both tried to gain control. By the time they reached the door that led to the demon prince’s bedchambers, Diavolo had won, biting and sucking on her lower lip to make her gasp and give him the opening he needed to shove his tongue into the hot, wet cavern of her mouth.

Both of them moaned at the same time; him for how sweet she tasted, and her for how good it felt, having his wet muscle sliding against hers in a passionate dance. She then pulled away from him to play with his lower lip, making him groan into her mouth as she smirked. “Eager, aren’t you my King?~” She teased him as he took possession of his lips again, using his magic to open the door. 

“I’m always eager when it comes to you, babygirl .” He replied just as smugly, knowing exactly how much that pet name affected the woman. The words were enough to see her pupils dilate with want. He stepped inside the tastefully decorated room, shutting the door with a firm kick before setting his human lover down and pinning her to it, her hands above her head. “Now, I have a surprise for you. We’re gonna spice things up. Differently. ” He told her, his voice dropping down by an octave or two so as to mess up with her even more. 

She moaned at the gravelly tone of his voice. “What…?” She breathed out, looking up at him through hooded eyes, looking every bit the seductress he knew her to be.

“Why tell you when I can show you, hmm? Come with me.” He answered in that same low tone, releasing her hands and winding an arm around her waist to lead her to the bed. However, instead of laying her down, he brought her to stand in front of a full-body mirror, which was also equal to the horizontal length of his bed, taking a place behind her. “I don’t understand, Dia.” She said, her eyes meeting his molten gold-like orbs in the mirror.

Instead of a reply, the demon kissed her nape, sweeping her long tresses onto one shoulder. His lips then travelled the entire expanse on her neck, marking her flawless skin with numerous little bites and dark hickies. It was enough to have her panting, her arms looping around his neck behind her. He couldn’t help but chuckle at how easy it was to get her all wanton and needy for him. Pouting, the blonde human ground her ass against the demon’s crotch, making his breath hitch at the sudden friction against his half hard member.

"Fuck Ariadne…" He let out before stopping her from repeating the action. "No, babygirl. This night's supposed to be all about you." He continued, looking at her through the mirror. "I want you to see how exquisite, how beautiful you look as I push you over the edge and have you screaming in pleasure over and over again." 

A pretty flush bloomed across her face and her entire being heated upon hearing his words. “Seems like you like the idea, sweetheart~” He teased knowingly letting his hands trail up and down the revealed skin of her sides, causing shivers to run down her spine. “I… you… that…” She sputtered in her attempt to respond before giving up that idea and using the opening she had to grind her backside against his crotch once more. 

Taking the hint, the redhead’s hand moved to unzip the slinky number she had chosen to wear that evening. Slowly, inch by bloody inch, he slid the zipper down, building up her anticipation. She tried to hurry him but he ignored her, wanting to take his own sweet time in undressing her. Once the zipper was completely undone, he slowly slid the dress down her body, only to be rewarded with an unhindered view of her nude torso as the outfit didn’t require her to wear a bra. Then, his demon form flashed as he tore her silk pantied to shreds with the help of his claws before settling back in his everyday form, not a button out of place.

This slow torture had the woman going insane as she grew wetter with every passing second. Her breath got caught in her throat when she saw his reflection shift forms and bit back a moan as he proceeded to shred the silken piece of clothing that was keeping her from being completely nude. She grumbled at how unfair it was that while she was totally bare, he was still wearing clothes. He chuckled. “You don’t get to say that after the stunt you pulled while we were having dinner, darling.” He responded smugly, reminding her of just how much teasing she had put him through earlier in the evening. Then, without any warning, he turned her around to face him and lifted her up. She yelped before wrapping her legs around his waist as he carried her to bed this time, laying her down in a manner that if she was to turn her head to the right, she would be able to see her entire body reflected in it.

Her mind wandered, imagining how the two would look when connected intimately, with him fucking her right into the bed she was lying on.

With her distracted, the prince took one of her legs in his hands and kissed the woman’s feet before moving up to her ankle, coaxing out a gasp from her painted lips. He took note of her reaction, storing it for later before kissing his way up her leg, her thigh and her stomach until he reached her breasts. He placed a kiss on a perky nipple before flicking his tongue at it, making her keen and moan loudly. “Ooh… that’s a pretty sound. Keep on making those, babygirl~” He told her. The next lick made her close her eyes and throw her head back. Diavolo immediately pulled back and she whined. “Eyes on the mirror, beautiful.” He commanded. Not wanting to test him, she did as she was told and was rewarded with a nip on her collarbone. “Fuuuuuuuuuuuck Dia~” She cried out in pleasure, body arching up to meet his clothed one. However, she somehow managed to still keep her eyes on the mirror, looking at her reactions to everything he was doing.

Satisfied, the redhead moved down to wrap his around one stiff bud while rolling and pinching the other between his thumb and index. And with how sensitive her nipples were, she was already moaning and cursing loudly. Then, his fingers and mouth switched places, playing with her other nipple and torturing her further as she bucked her hips in search of some friction.

“If you want something, you just need to ask Aridane.” He told her slyly, knowing how much she hated being direct in bed. She tried to plead with her eyes but he ignored her, choosing to suck hickies all across her throat instead. She gasped, then moaned before giving up and begging for what she wanted him to do. 

“I want you, Dia. I need you. Fuck me.” She cried out to him, a brilliant blush decorating her perfect cheekbones as she quickly turned her head to look at the mirror once more. It was surprising how the woman could be a seductress one moment and then transform into a blushing mess in the next one.

The moment she said those words, his clothes seemed to evaporate into thin air, leaving him in all his naked glory. “Look at me.” He growled before kissing her deeply and passionately the moment her face turned his way once more. Then, he opened his palm, a bottle of lube materialising into it. Since they had had a go at each other before leaving for the date as well, he didn’t really need to prepare her. But that didn’t mean he wouldn’t do what was needed to make it easier for her when he entered her. 

Once he was sufficiently lubed up, he lined himself with her sopping pussy, nudging her entrance lightly. “Don’t tease, Dia.” She pleaded before her expression changed to one of shock and then absolute pleasure as he entered her slowly. “Oh fuck. Oh fuck. Oh fuck.” She chanted, her head turning to the right. The sight of their naked bodies connected had her entranced. 

Before long, he bottomed out in her, groaning at how good it felt to be hugged by her wet walls. He then waited until she was adjusted to his size. Once she was, she bucked her hips into his, making them both gasp before it turned into a loud, drawn-out moan of his name on her part as he started fucking her. Slow at first, he slowly built up the pace, praising her and whispering dirty things in her ear at the same time. The quiet of the room was replaced by the sound of skin slapping against skin and it smelled of sex. When he knew that she was close, he reached between their sweaty bodies, his fingers finding her swollen clit and tracing tight circles onto it, sending her over the edge almost immediately. A few thrust later, he followed her into the oblivion of pleasure as he emptied his load inside her.

Once they had gotten down from their shared wave of ecstasy, he pulled out his long-softened shaft from her pussy, making her groan. "Stay here. I'll draws us both a bath." He spoke softly, kissing her forehead before getting up. However, she pulled him back into her arms. "No. Not yet." He replied, snuggling into his chest. 

"I love you, Dia."

"I love you too, sweetheart."

Notes:

Hey fellow thots. Just in time for Day - 6, I present some Diavolo smut. This was definitely a difficult piece because halfway through writing, I hated what I wrote and decided to start from scratch. So, this might seem as a rushed piece and I sincerely apologize for that. Theatre rehearsals also fucked up my schedule, lol.

The prompt list I'm following is by @wittythreads on Tumblr. She goes by Elvishdork on AO3.
