🔥❄ #luckae | NSFW🔞, power bottom kaeya & sub top diluc, messy blowjob time 😳 | modern teacher/college au where professor diluc gets his daily visit from his favorite student kaeya💗

thread starts below!⬇️

Diluc knew he shouldn't have let Kaeya take the reigns as soon as he walked into his office. But he can't resist that devilish gleam in his lustful gaze, the way his pierced tongue runs along his bottom lip with a quick flick, legs that run for miles straddling his lap.

He's utterly weak for the mischievous student, and Kaeya abuses that to the fullest extent. Honestly, Diluc can't even be bothered to be mad because Kaeya is the most fascinating person he knows. And the most horny.

The young male is straddling his lap, plush ass directly over his hardening cock. Diluc plays with the fleshy globes while they devour each other, and Kaeya is happy to rock back in his hands. Diluc whimpers softly against his mouth when Kaeya digs his teeth into his bottom lip.

"Don't bite so hard." Diluc mumbles, refusing to stop the kiss when Kaeya's tongue is caressing every sensitive spot inside the hot cavern.

Kaeya only hums, and Diluc can feel the metal rod of his piercing on the roof of his mouth. "No." He simply states.

He can't argue with that, and continues on with their passionate liplock. Kaeya starts to grind down harder on his cock, and Diluc shamelessly buckles into him with a loud groan. His hands gripping Kaeya's ass so hard, he thinks he'll leave brusies and the thought gets him harder

"Luc," Kaeya pants when he finally retreats, leaving Diluc with swollen cherry lips that nearly match his eyes. He stares up at Kaeya's ever cool expression, the only thing giving him away is the very obvious bulge in his pants. "When are you going to fuck me?"

Diluc chokes at the question, eyes widening behind the frames of his glasses. "We can't." He refuses, but that doesn't detour the male as he grinds back harder and faster on his cock to entice Diluc.

Kaeya smirks, "And why not? We both so /obviously/ want to."

"And there's no point to deny it any longer when we've done so much else together." He continues, running his hands through Diluc’s hair at his scalp and it almost him putty in the student's hands.

"I have my principals." Diluc breathes, trying not to create a mess in his pants.

He hears Kaeya bark a laugh, and Diluc pinches his ass in retort and he smiles in satisfaction when Kaeya yelps. He slaps the older man's hand, "Bad professor. Do not damage the goods."

"We really can't, Kaeya." Diluc continues to insist.

The blue haired male hums with a tilt of his head as he calculates his next move. "Why?"

Diluc sighs in relief when Kaeya finally stops the rocking of his hips, "Because...I don't think I'd be able to let you go after."

Kaeya contemplates this for a moment before grinning wide, "I don't want you to. I /want/ to be all yours and I /want/ you to be all of mine." The possessiveness of his tone makes Diluc shiver. Yeah, he is never going to be able to escape the clutch Kaeya has his heart in.

The chair he is sitting in is suddenly pushed back, Kaeya flipping his hair back over his shoulders and ties it up in a loose ponytail. It's like a reflex at this point because Diluc's cock jumps in his pants, and he bites his lower lip in anticipation.

Diluc can see Kaeya's pierced nipples through his shirt, and how he longs to lap at them. The other snickers quietly, leaning over to palm his quivering thighs. "Aw, so cute to see you excited over getting your cock drooled on by me, Professor Diluc."

Kaeya's voice drops into a sultry tone that makes heat curl in his lower abdomen. Diluc groans when Kaeya's hands expertly maneuver him out his pants, and immediately wrap his fist around his throbbing cock.

Kaeya still hovers above him slightly before leaning down to spit right over his fist, pumping it fast now over his shaft. Diluc tilts his head back with a high moan at the softness of his palm, imagining just how wetter and softer Kaeya's hole would be.

"I was so surprised the first time I saw your cock, Luc. For such nerdy prof like you, you've got the fattest cock I've ever had the pleasure of getting off." Kaeya comments, kissing the corner of his lips while his thumb swipes over his leaking tip.

Diluc gasps softly and thrusts into Kaeya's grasp, biting on his lower lip when the other continues. "I'd have to stretch myself open with at least 4 fingers to get you all inside of me. Hm, I'd cum so hard with just you fucking my ass. I bet you'd like that, Luc."

Sinful lips whispers those words of filth directly into his ear. He trembles in Kaeya's hand, biting his lower lip from whining at the very image of his brilliant student taking his cock without as much as a flinch. Encouraging Diluc to absolutely destroy him.

Kaeya is definitely size queen, and he's never been happier to have a big dick.

But, doom comes knocking on their door. Literally.

Three firm knocks ring throughout the room, and jolt both men from their reverie of lust. Diluc's eyes swing to the clock on the wall, cursing softly. "Shit, he's early."

Kaeya blinks, but then the door knot is squeaking, indicating the door is being opened and Diluc flails in panic. His own life flashing before his eyes, all because he couldn't resist the temptation that is Kaeya Alberich.

"Get under!" He squeaks frantically.

Kaeya stares at him incredulously when Diluc shoves him underneath his mammoth of a desk, hissing at Diluc about how he'll ruin his clothes kneeling here. He manages to cram Kaeya's figure in the space just as his door swings open.

He's always hated how big his desk is, but he's extremely grateful right now. He gets his chair as close as possible to the desk as well, his stomach nearly touching the edge to hide the fact his dick is still very much out.

"Professor Albedo," Diluc grins, breath uneven from the adrenaline that rushes through him. "It's nice to see you."

The blonde smile gently. "I know I'm early but I'm afraid I double booked myself. Do you mind if we discuss the syllabus for next semester now?"

Diluc can only pray he doesn't notice the flush decorating his ears, or how he hasn't gotten up to greet his fellow coworker. "Of course, please have a seat."

All is well for a few minutes as the two men discuss, enough that Diluc's cock begins to soften but Kaeya...

Kaeya, who always seeks excitement in some way, reaches out carefully to slot his lips over Diluc's tip that still dribbles precum.

The action makes the professor jump so abruptly, his knees hit the desk making the entire structure rattle.

Diluc groans and reaches under to try and bat Kaeya away, making it look like from Albedo's perspective he is soothing his battered knees.

"Are you all right, Diluc?"

The redhead's laugh is strained. "Sorry, just felt a fly trying to bite me."

The fly, who more-or-less is Kaeya, sucks on his head in response when his hand tries to yank him away but no use. Albedo only raises a brow before he continues with the structure of his class for next semester. But Diluc's mind is only on the hot mouth that slides over his cock.

It takes every ounce of power for Diluc to not moan out obscenities when Kaeya suckles gently and softly, rolling his balls between his fingers while the metal rod of his piercing rubs against him. He twitches when Kaeya takes him even deeper.

Diluc's hand death grips the edge of his desk, fingers turning white while his concentreated gaze focues on a point behind Albedo's head. His knees almost hit the desk again when Kaeya decides to deep throat him, firm and slow, from tip to base.

He hears Albedo still rambling but Diluc has given up all hope of listening, instead he savors how Kaeya's throat squeezes around his girthy cock and he even hears the student choke a bit when he forces himself down. Diluc covers up the sound by clearing his throat.

Kaeya is nothing but persistent, continuing to repeatedly choke around Diluc's cock until spit dribbles down the sides and he can picture how debauched Kaeya looks right now. Lips stretched wide, cheeks bulging slightly as he tries to take every inch...

...and Diluc wishes he could see those intense eyes bore into his while he fucks that hot mouth. Kaeya silently begging him to coat his tongue and face in thick cum, clinging to his skin and making the student as his.

"Diluc?" Albedo's raised voice finally catches his attention

Diluc hisses when Kaeya pinches his thigh to answer. "Yes?"

"Are you feeling well? You seem distracted." Albedo frowns.

"Actually, forgive me, Albedo but I'm afraid we'll need to continue this another time. I'm-I'm not feeling well."

Diluc has to bite his cheek when Kaeya pulls back to stroke him fast while he licks his balls, full and ready to explode at this point.

Albedo seems disappointed at cutting their convo short, but Diluc hardly cares. He merely waves goodbye to the professor who wishes him well.

Diluc sags into his chair and pulls back from under the desk where Kaeya finally emerges again. His own cheeks heavily flushed, and but he looks giddy, "Finally! Now, I can get back to sucking you off how I really want to."

Kaeya wastes no time then, planting his hands firmly on Diluc's hips and bobbing his head with renewed vigor. The professor doesn't hold back his reactions now, and his hand rests on the back of Kaeya's head while he moans enthusiastically.

The wet sounds of his mouth are louder now while Kaeya fucks his mouth full of Diluc's cock, needy and hungry for it. When the younger man hums around him in a steady rhythm, Diluc jerks his hips causing Kaeya to choke but he doesn't pull back. "Yes, yes, Kaeya right there!"

He pants with his head thrown back, letting himself savor Kaeya and his wonderful actions. The younger male then holds himself, working his throat muscles around the shaft, lips brushing his base as he demands Diluc to cum down his throat now.

And Diluc has no other option but to obey the demand. Both of his hands now pushing down on Kaeya's head while he sheathes himself in that tight throat with a powerful groan, and a hard thrust. Emptying himself while the other greedily swallows his release with quiet moans.

Diluc sees the stars behind his eyes while he cums, and it takes several moments to come back to reality. Kaeya cleaning his lips with his tongue and a wicked grin while he tucks Diluc back into his jeans.

"Now imagine how much harder you would cum inside of me."

Diluc's cock gives a twitch and Kaeya snickers at him as he climbs back on his lap to kiss him, messy tongue and all.

He knew this wouldn't be the last time Kaeya pulls his strings.
