Chapter Text
Lucifer smiled as soon as Barbatos opened the doors to the Demon Lord's castle before he had knocked on them. "Well, good afternoon Barbatos. Long time no see." That was obviously a lie. They had just seen each other yesterday after Diavolo's return.
"Good afternoon to you as well, Lucifer. I have to say, the Young Master is very... let's say he's been eagerly awaiting your arrival." Barbatos' eyes gleamed with excitement.
"Is that so?" The smile on Lucifer's face grew, a mischievous glint in his eyes. "Well, I should probably not keep him waiting then. After all, it would be rude of me."
" Of course. It's best not to keep the Young Master waiting. If you would please follow me." Barbatos' smile was hidden by his hand, and the two of them made their way to Diavolo's bed room.
Once they both were standing in front of the doors to Diavolo's bedroom, Lucifer knew what he was getting himself into. Shit. This was something called karma. And he did not like it one bit.
. . .
"Strip," Diavolo commanded. The prince sat down at one of his chairs, a glass of Demonus swirling in his hand. Lucifer did as he was told. Somewhere along the line, he shifted to his demon form.
"On the bed, and make yourself comfortable," Diavolo said, gesturing to his bed with his free hand. Once again, Lucifer did as he was told.
The first thing he noticed, was how big Diavolo's bed was. He'd slept on it more times than he could count, when he'd been too exhausted from paperwork or spending the night with Diavolo.
Lucifer took a seat on the bed, the sheets silky soft against his bare legs. His ass was in the air and his face pressed down on the pillows. His length twitched with arousal. Lucifer only hoped he'd be able to walk back home after this.
Diavolo came up behind him and pulled his wrists together. He secured them behind his back with a pair of handcuffs. Lucifer didn't even notice him moving until he felt the cool metal around his wrists.
"Are those necessary?" Lucifer asked.
"Yes. Yes, they are," Diavolo answered, sounding pleased. Lucifer only huffed and rolled his eyes, which gave him a slap to the ass.
Lucifer made a surprised sound but bit his lip. Fuck. He's getting needy. But he won't be broken that easily.
Diavolo moved his hands along his back, tracing every curve of his skin, every dip in his spine. "I love seeing you like this," Diavolo purred. Lucifer shivered under his touch, his skin tingling and his length growing. "I love seeing you at my mercy. You're always so in control, aren't you?" Diavolo traced the edges of his wings, the tips fluttering at the attention. Diavolo's words, his tone, everything, were slowly breaking down his barriers. Something only Diavolo could do. Dammit. His resolve is fading with every touch and every syllable that makes its way past Diavolo's soft, tender and perfect lips.
Diavolo trailed his fingers along Lucifer's back once again, stopping at his waist. "Don't move." Lucifer stilled, the anticipation almost killing him.
Diavolo reached over and grabbed the bottle of lube. Lucifer heard the click and a squelching noise, followed by the feeling of slick fingers on his entrance.
Lucifer inhaled sharply.
"So pretty, so sensitive," Diavolo purred praise into Lucifer's ear, whose wings trembled. Diavolo lowered his voice to a whisper, "I can't wait to stuff you full of my knot. Perhaps some of my eggs too,"
"Ngh!" Lucifer gasped and arched his back, his ass backing up into Diavolo's fingers and his wings spreading out.
"Oh?" Diavolo chuckled. "Does my pretty little bird like that? You want to take the whole clutch from me, don't you, Luci."
Lucifer whined at the dirty talk and tried moving his ass back up against Diavolo's fingers in a futile attempt at getting more. More than he dare ask to say.
"You're so desperate. What happened to all that pride, Lucifer?" Lucifer didn't answer, only whining and gasping into the pillow. "Well, I'll let you in on a secret. I'm not feeling all that patient either," Diavolo whispered into his ear. "Perhaps I should stop teasing, huh?"
"Please," Lucifer said, his voice quiet and his throat dry.
Diavolo pulled his fingers away and Lucifer almost whined at the loss. Lucifer heard the shuffling of clothes but he didn't dare look back. He already knew. Diavolo was in his demon form, his absolute monster of a cock with that precious knot he wanted. He shivered. He needed it so badly. And the promise of eggs... it sent the demon within him into a craze.
The next moment, Diavolo's thick, throbbing, warm cock was pushing inside of him. Diavolo was taking his time, teasing him .
"Oh fuck," Lucifer gasped, his fingers clutching the sheets.
"So tight for me," Diavolo moaned, his claws digging into Lucifer's hips. "It's as if you were made for me. Made for me to fill with my cum. My seed, my knot. Oh, I'll fill you up, my love," Diavolo purred. Lucifer shivered and moaned and clenched harder.
Diavolo bottomed out, the knot kissing his rim. Diavolo leaned over, his chest against his back, and his breath fanning his neck. "You ready?" Diavolo asked. Lucifer nodded, biting his lip.
With a snap of his hips, Diavolo started to rail him. It was brutal. Diavolo was truly the embodiment of demonic stamina. His hips slammed against his ass with the force of an elephant and the speed of a human world jet. With every thrust, Lucifer could feel the knot. It was driving him mad.
"Hngh- ! Oh, fuck!" Lucifer cried out, his eyes rolling back and his poor untouched length bouncing against his stomach with each sharp thrust of Diavolo's cock into his ass.
"That's it. Let me hear you," Diavolo grunted, his hands moving from his hips and sliding up his torso, his fingers tweaking his nipples.
"Ng-! Ah-!" Lucifer gasped. "S-so close-!"
"Already? You really are desperate for me, aren't you."
"Yes! Oh fuck- please, I'm so fucking close," Lucifer cried, his eyes screwed shut and his mouth open, drool dribbling out the corner of his mouth. Diavolo hummed and moved a hand to wrap his fingers around his leaking cock, pumping it in time with his thrusts.
Lucifer screamed. His vision went white. He saw stars. "Ah-!"
Diavolo's thrusts began to stutter and his movements became sloppy. "Gonna fill you with my knot . I'm going to give you my whole clutch, fill you up with my litter ," Diavolo growled into Lucifer's ear. And keeping true to his words, he did just that.
Diavolo buried his knot inside Lucifer and came with a viciously hard bite to Lucifer's neck, making him bleed. Lucifer whined. But Lucifer didn't have any time to say anything before he felt an egg being pushed through Diavolo's cock and into him. The only thing Lucifer could do was whine and moan. It was a single egg but it was enough to break him. He came for the second time that night. Once Diavolo pulled out and plopped right beside him, he snapped his fingers and broke the handcuffs around Lucifer's wrists.
Diavolo chuckled. "Did I... accidentally go too hard?" Lucifer's ass was still high up in the air where he left it.
Karma. Yes. Karma yes indeed.
