"Oh? What do we have here?"

Kaeya pulls at Diluc's underwear and releases it with a snap. Diluc's cock throbs and Kaeya eyes him hungrily. His face heats up.

"What? They're just briefs. Nothing you haven't seen," Diluc retorts, crossing his arms.

"I suppose not," Kaeya muses, gently prying his arms away from his chest.

"You're wearing briefs too," Diluc mutters.

"Sure, but yours are /white/."

Diluc wore a deadpan expression. "An astute observation, Sir Kaeya."

Kaeya laughs and pecks his nose.

// continuing this nsfw #kaeluc 🦚🦉 thread

warning: it's gonna get rather explicit

Diluc scrunches his nose and Kaeya can't help but burst into laughter again, collapsing into his chest.

Kaeya's crotch slides deliciously against Diluc's and his laughter quickly morphs into a moan.

"Someone's eager." Diluc teases, mouthing at his ear and stroking his hips.

Kaeya pulls away.

"You have no idea how delectable you look right now," he whines.

Diluc raises an eyebrow. "You were just teasing me about my choice in underwear."

Kaeya groans and it's Diluc's turn to chuckle. He kisses Kaeya's knuckles in apology.

"Show me?" he murmurs.

"First off," Kaeya presses a kiss to his jaw. "You're flushed all the way down," Kaeya trails kisses down his neck, sucking lightly at his collarbones, and kissing down to his sternum, "to here."

"Mhm," Diluc rumbles, his thumbs tracing circles onto Kaeya's waist. Kaeya shivers.

"And these sweet, shy things," he continues, licking and drawing a pink nipple into his mouth as he rubs and pinches the other. Diluc's fingers dig into Kaeya's waist. He tangles a hand in Kaeya's hair, Pyro-warmed fingertips gently stroking his head. Kaeya melts into his touch.

"How am I going to get anything done when you're like this?" he groans when Diluc starts massaging the base of his skull.

Diluc doesn't seem to be faring better. "Go faster then," he pants.

Kaeya releases his nipple with a pop and Diluc cries out, hips stuttering.

"Please, K—"

Kaeya surges up to kiss him, careful not to touch Diluc's erection. Diluc's hands slide towards Kaeya's ass but they are intercepted and pinned above Diluc's head.

"Not yet, love," Kaeya says. Diluc whines.

"Breathe," Kaeya murmurs, resting his forehead against Diluc's.

Diluc wills himself to keep still, focusing on the pressure of Kaeya's hands on his wrists in a bid to ignore the maddening friction against his twitching member.

Kaeya still has not removed his underwear.

Slowly, his breathing evens out.

"Good boy," Kaeya croons and he releases Diluc's hands. Diluc is rewarded with a languid kiss and he wraps his arms around Kaeya, relaxing into his touch.

"You alright?" Kaeya asks, searching his face. Diluc nods.

Kaeya kisses a trail down Diluc's torso, settling on his stomach between Diluc's legs and caressing the inside of his thighs.

"Tell me if it's too much, hm?"

Diluc doesn't have time to respond before Kaeya starts nuzzling his crotch.

Diluc gasps and Kaeya wraps his lips around his bulge, sighing into the soft cotton. Diluc shivers as warm air curls around his cock and it pulses, spilling precum into his briefs.

Tasting Diluc's arousal makes Kaeya achingly hard and he fights the urge to rut into the bed.

"Pent up, are we?" Kaeya teases, his lips ghosting over the fabric.

Locking eyes with Diluc, Kaeya laves his tongue over the fresh spot of wetness and Diluc arches into him, his head hitting the headboard with a soft thud.

"Kaeya! Ngh—"

Diluc grips the sheets as he watches Kaeya licking and sucking at him like a man starved, drooling all over him and lapping up the dribbles of precum that seep through.

His white underwear is soaked through and leaves nothing to the imagination.

He sees the purple head of his cock straining against the elastic as Kaeya tongues at the seam, rubbing it into his slit. Diluc keens, feeling the familiar tug in his gut.

"Close!" he whimpers, pawing at Kaeya's face.

But Kaeya pays him no mind.

Instead, he seems to redouble his efforts, sliding his hand through the stretched leg hole. He traces the rim of his puckered hole, gathering the excess precum before pushing one finger in.

Diluc shudders and soon he's rocking into Kaeya's hand.

Kaeya adds a second finger.

It doesn't take long for Kaeya to locate Diluc's prostate. He crooks his finger, his mouth still latched on his cock and swirling his tongue around the head.

"Wait please—ngh—too much! I can't—I need—" he babbles, desperately pushing at Kaeya's head.

"Yes you can, sweetheart. You're doing so well," Kaeya coos, his fingers massaging Diluc's prostate.

Diluc sobs as he approaches his peak.

"That's it," Kaeya murmurs against his cock. "Cum for me."

Diluc wails, pouring cum into his underwear as he bucks into Kaeya's mouth. Kaeya latches onto him, sucking and swallowing around him.

Kaeya continues suckling even after Diluc calmed down and has softened in his mouth, only stopping when Diluc whimpers with overstimulation.

Kaeya wipes his mouth with the back of his hand before crawling up and pressing a kiss to Diluc's forehead.

"You did so well, 'Luc. Let's get you cleaned up, alright?"

Kaeya removed the soiled garment before gently cleaning up a very pliant Diluc with a damp wash cloth.

Kaeya cleans himself up quickly before returning to Diluc's side.

Kaeya pulls Diluc to his chest, pressing kisses to the back of his neck and his shoulders.

Diluc sighs contentedly, snuggling closer when he feels Kaeya's erection press into his back.

"You didn't—"

"It's alright," Kaeya reassures him. Diluc frowns and wriggles out of his grasp.

He swipes the vial of oil from the nightstand, pouring a generous amount over his fingers before Kaeya can stop him.

"We just cleaned—mmph!" Diluc smears the oil over Kaeya's cock.

"You minx," he chuckles as Diluc settles against him again, rolling his hips so that Kaeya's tip catches on his rim. He pushes back hard against Kaeya and yelps when Kaeya's tip breaches the tight ring of muscle. Kaeya places a steadying hand on his hip.

"Breathe, 'Luc." He presses kisses to Diluc's shoulder as he adjusts to the intrusion.

When Diluc's breathing evens out, Kaeya holds him in place. "Let me."

Kaeya eases into Diluc, murmuring praise and sweet nothings into Diluc's ear.

"You take me so well," Kaeya groans when he's fully sheathed in Diluc's tight heat. Diluc clenches around Kaeya's girthy cock and Kaeya kisses Diluc's nape in apology.

"Too much?" Diluc shakes his head, but Kaeya knows he's putting his comfort aside for him.

"I'll be gentle."

Kaeya pulls him close, hand over Diluc's heart as he begins rocking slowly.

Diluc clutches Kaeya's arm, mewling at the delicious friction, the feeling of fullness when Kaeya pushes in overwhelming.

Kaeya grinds deep into Diluc and they moan and shudder together.

Diluc turns his head to kiss Kaeya, licking into his mouth and whimpering when Kaeya angles his hips to grind against his prostate.

Diluc's hand brushes against his tender length and he clenches.

"Archons, 'Luc, you're so tight around me," Kaeya groans, rolling his hips.

"Inside, Kae," Diluc gasps and Kaeya's thrusts grow erratic.

He sees white when he cums, clinging to Diluc as his cock pulses, shooting his load deep into Diluc's belly. Diluc swallows his groans, soothing him with kisses and his Pyro-warmed fingers in his hair.

They lay panting against each other's lips, their kisses chaste and sweet. Kaeya moves to pull out but Diluc stops him.

"Can you stay?" he asks, chewing on his bottom lip.

Kaeya wraps his arms around Diluc. "Anything for you," he mumbles, nuzzling into his neck.

// epilogue

Diluc mindlessly traces patterns on Kaeya's hands as they bask in each other's closeness.

Kaeya breaks the silence. "So, you see my point about your tighty-whities?" Diluc splutters.

"My /what/?"

// end
