Work Text:
Lucifer’s head was pounding. The migraine had only worsened throughout the day, and Mammon’s antics had just shot his last nerve. It was precisely at this point that he walked past the bedroom of the twins and something made him halt.
He knocked to no answer. Upon opening the door, he found the room empty.
Interesting!
Given the house was not currently filled with bellows from Mammon, squees from Asmodeus and rhythmic “I’m hungry”s from Beelzebub, then Belphegor would be either in the attic or the observatory.
Or perhaps sprawled face first onto the couch.
He found Belphegor curled like a cat in your lap, you stroking his hair.
His heart (which if forced to admit he possessed he would deny to the very last) all but melted.
Your hand came up and he reflexively reached out and pressed his lips to it.
“Beloved.”
Your murmurs always left him feeling warm and relaxed. He leaned in to take the offered kiss from your lips.
“How are you?”
He nodded.
“Migraine huh?”
It was amazing how well you could read him. Your fingers reached out and he bent to allow them to ruffle his bangs.
“Think you can help me? My leg is falling asleep and I really need the bathroom.”
Lucifer blinked, then with no delay swept Belphegor’s sleeping form into his arms.
"My hero!" You sighed dramatically, then laughed when Belphegor nuzzled into his shoulder, and murmured something about smelling good.
“I’ll meet you in your room.” You stood up carefully and pecked his lips to dispel his embarrassment, before disappearing promptly.
Lucifer huffed. His plan would have to wait. He took Belphegor to his bedroom, and attempted to return him to his bed only to find out that despite looking relaxed, the boy’s grip was all but iron.
With that in mind, what else was there to do but take him to his own bedroom and hope he would still be able to get some sleep despite the limpet in his arms.
As he walked to his room, Belphegor continued to nuzzle, leaving Lucifer slightly flustered.
He tried to school his face because the last thing he needed was gloating from any of his brothers at the sight he currently was presenting them.
He still had a migraine, and it was somehow getting worse.
He wished he’d just gone directly to bed and foregone the revenge plan, but such was hindsight.
With the help of magic, at least he was able to change into comfortable clothes for sleeping.
He moved towards the bed once more attempting to dislodge Belphegor, unsuccessfully.
“mmfphsk”
The soft garbled words tumbled out of the sleeping demon.
Lucifer all but melted again. Still so young. Still so adorable. Belphegor had been soft-faced even as a new angel, and Lucifer was relieved that despite all the difficulties faced, his features hadn’t changed all that much.
“fffer”
The demon blinked.
“Lu-ciferrrrr ngnh”
Belphegor was apparently dreaming of him. Schooling his mind to focus, he gently dislodged the hand tangled in his shirt. Slowly, he placed the boy on the bed, trying his best not to topple over.
Belphegor had relaxed his grip on one side, but not the other, so there was little else to do but to slide carefully into the bed.
As though feeling the shift in the mattress, Belphegor yawned and immediately uncurled his freed legs, only to tangle his, hitching a knee upwards.
Blushing virgin he was not, but neither was he used to being seduced by one of his brothers, who wasn’t Asmo. And especially not one from the Anti-Lucifer League.
Belphegor’s lips were by his chin almost, and the barely there brushes of his neck were not useful for lowering his heart rate.
Belphegor huffed and wrapped his arm around Lucifer’s torso. His soft murmurs continued tickling the sensitive skin at his throat, and he found to his great embarrassment, his whole body reacting to the attention.
He curled an arm tentatively around the boy, surprised when that only spurred him, and he felt a very enthusiastic knee brushing against an unintentionally sensitive part.
He let himself feel the warmth from Belphegor, the soft breath on his neck, and, to his surprise, the boy’s own response.
Despite being unused to this sleeping arrangement, nevertheless he appreciated its advantages.
He could observe the steady sway of Belphegor’s hair, the occasional flutter of full lashes against fuller cheeks. The way his lips parted every now and then as though intentionally kissing his neck. The feel of his warm, steady hand on his chest.
He brought up his own to cover it, marvelling in turn at the contrast of nail colours, and how well they fit together.
Then Belphegor snorted in his sleep, fisted Lucifer’s shirt and drooled on his shoulder, which drained all the romance from the moment.
Lucifer could feel his migraine worsening. His tendency to shame himself for having feelings was something you had been working on unteaching him, but you were currently not there to help him focus his mind.
Belphegor was the brother he felt his selfishness harmed the most. Whatever else could be said about the events with Lilith, his decision to lock him up instead of holding space for him to grieve, was one of the things he still struggled to forgive in himself.
He heard the door open and then you were by the bed, in full pjs and the world regained colour in his eyes.
“ I see someone made themselves comfortable.”
Lucifer smiled.
“He’s a lot less trouble when he’s being adorable.”
You smiled back:
“He is pretty adorable.”
The wince was almost unnoticeable, so he was surprised when you placed a palm on his cheek to bring him to meet your eyes.
“I love you dearest.”
You placed a compress gently to his forehead before kissing the tip of his nose and flustering him.
“This should help you sleep now.”
He offered you a tired smile, with his gratitude, and welcomed your kiss on his cheek.
“I think we need to take a page out of Belphie’s book.”
Lucifer nodded.
Belphegor picked that moment to moan out his name.
Lucifer froze.
Your eyebrows raised, and your lips quirked in amusement.
More garbled sounds from Belphegor came out, while you gently were trying to decompress a heavily embarrassed pride demon.
Belphegor struggled a bit before rolling on his back to hiss and snore lightly.
Lucifer’s cheeks almost matched his eyes.
You pressed a kiss to his cheek.
“Well, that was enough adventure, shall we sleep dearheart?”
The demon nodded and rolled into your welcoming arms, relishing the feel of your lips on his forehead.
“So beautiful. So precious.”
He opened his eyes wide, and you were afraid he was about to cry when something jolted you both.
“mmnhr Luci’frrr”
You giggled, relishing the blush on his face.
“S’ok, we can sleep now, right?”
He nodded and you pressed another kiss to his forehead.
“Good night my love.”
“Good night, my heart.”
The room was quiet in the darkness, then Belphegor whined and huffed, apparently unimpressed with whatever his dream was.
After a few more minutes you could both hear Lucifer’s name being called punctuated by the odd flail of arm or leg.
The demon lowered his eyes, so you kissed his forehead and squeezed him tighter.
At this moment, Belphie rolled, inched forward, and attached himself blithely to your arm, wedging fully around Lucifer.
You felt the bed shift, while the younger demon nuzzled into Lucifer's shoulder. Squeezing gently at Belphegor's arm seemed to soothe him.
He stopped moving altogether, and sighed, before groaning out Lucifer's name.
Said demon thought he would combust. You smiled at him, to hopefully dispel some of his sense of shame and awkwardness.
You sat like that, Lucifer barely meeting your eyes, you brushing your lips on his bangs.
Seemingly appeased for the time being, Belphegor was still.
You let yourself take pleasure in your synchronised pulses and the adorable blush on Lucifer's cheeks.
Silence spread, and just when you had both closed your eyes there was another snort of Lucifer’s name.
The pause was short lived, succeeded by a deep sigh and a tongue click:
“You suck!”
