Lucifer doesn't need anyone's permission to take care of his children.
Jack and Marie have been given separate bedrooms. Whenever Lucifer checks on them in the middle of the night, they've never stuck to their own, not even on the nights they actually do sleep. Like tonight, where Marie is curled up around Jack and Jack is tucked into her, and their graces are so wrapped up together that it's hard for even him to tell that they're two beings. (It's like they wish they weren't.) He watches them for a minute. Jack kicks in his sleep, and Marie tangles her calf around it to keep him still. Warmth blooms in Lucifer's chest. They're perfect. They're his.
He greets them with his grace first. He lets it reach into them, a welcome guest between their matching souls. Marie's flickers to waking first, though she pulls her brother up with her, and Jack's the first one to open his eyes and see Lucifer over Marie's shoulder. Lucifer raises his hands to show he doesn't mean any harm, but there hasn't been a hint of fear from either of them.
"Rise and shine," he says, stepping closer to the bed. Marie rolls over. Jack follows, not a centimeter spared between them.
"It's not morning," she says. Jack's mouth twitches like he has to stop himself from saying it, too.
"I thought I could convince you to get up before then. For a surprise." That piques their interest, twin pairs of eyes locked on him and grace hanging onto his every word. He smiles. "You have to climb out of bed, though. I can't give it to you here."
If Lucifer tries, he can hear them speak to each other. He hasn't been given permission to do that, so he stays at the edges of their connection with each other, only catching stray whispers, safe here, trust him?, bright and pretty…, mama! The last makes his thoughts grind to a halt, the word echoing inside his head in Jack-Marie's voice.
"What's the surprise?" Jack asks. Lucifer swallows the sudden lump in his throat to answer.
"If I told you, it wouldn't be a surprise, would it?" Another huddle of traded whispers that lasts a much shorter time than the first, and both of them get out of bed.
He's always caught off-guard when he gets a good look at their vessels. They've changed a lot since Lucifer first saw them, when Jack was almost-not-quite-Sam and Marie was almost-not-quite-Mary, trying without words to explain to the Winchesters that they wanted to belong to the family, sensing love and begging for a little of it sent their way. It did not, as Lucifer hears it, go over well. But now Lucifer is here, and Jack and Marie have begun to experiment, to deviate. Jack still has Sam's eyes, but he's borrowed the shape of his smile from Lucifer's vessel. Marie has kept her long, blonde hair, but she has blinked a mole under her eye into existence. They want to look like him, or his vessel, which is as much him as anything else at this point for how long he's kept it, and Lucifer has never been more proud.
They hold hands when they follow him. They move in a way he has noticed makes the rest of the residents in this Bunker uncomfortable. Not mirrored, nothing so obvious, but like a dance, one responding to the other. Marie breathes in and Jack breathes out. Their footsteps build a rhythm that doesn't falter, even when one of them speeds or slows without warning the other. The Winchesters expect them to always act like people. Lucifer has gotten in the habit of rewarding them when they let themselves remember they're angels, too. He does it with a smile, letting his pride show in it.
Lucifer knows the layout of the Bunker very well. He might know about a few places the Winchesters don't. He's not sure if this is one of them, but that was the reason for waking the twins up before everyone else. A little privacy. A little space away from every interaction he has with them being buffeted by constant reminders that he's evil, that he wants to hurt them. He's a little insulted. It's like they don't know him at all. Jack and Marie are all his, and he loves them. He wants to give them everything they need and more.
Which is why they're taking advantage of the communal baths. They both look around curiously. This is a new room for them. Lucifer begins filling the main tub as they take it in, and the first sign he has that they're finished is Marie coming over beside him and sticking her hand into the stream of water that's spilling into it.
"How does it feel?" he asks. Marie's quiet.
"It's fine," she answers.
"She wants it to be hotter," Jack says. Marie makes a face at him, but from the way she's tensed, Lucifer can tell she isn't just feeling annoyed with her brother. He swallows down his instinctive need to find out why she's reacting like that (his theories are not comforting) and instead, brushes her hair aside to lay his hand on the back of her neck. He gives it a squeeze, rubs his thumb into the side, and lets go again before she gets overwhelmed. Even that makes her jump back a little when she's let go, eyes wide. Jack touches the tips of his fingers to the back of his own neck.
"You can have whatever you want," Lucifer emphasizes. He makes the water warmer. "Do you want to know what your surprise is? I'm going to teach you how to groom your wings." They don't say anything, and he looks up from the filling tub.
"We… have to do that?" Jack asks.
"Castiel didn't tell you," Lucifer says, and it's not a question but he gets two shakes of the head in response.
Lucifer should not be surprised by these things anymore. And yet.
He stows his anger. It will not help them now. Instead, he reaches out a hand for Jack to come closer. The minute the invitation is offered, Jack bounds across the room into Lucifer's space. "Can I see them?" Lucifer asks.
He hates the expression the falls over Jack's face. Who taught his children shame?
Jack relents. He reaches down and pulls his shirt up and over his head. Briefly, Lucifer looks him over. No scars on his body, no marks of any kind… his ribs seem much more prominent than they should be. He stretches out a hand and lays his fingers against Jack's side. He knew they were scrawny, but this is too much. He tries to remember how much he's seen them eat. It isn't nearly enough for a human body hosting the energy of an nephil. Jack's frozen, staring at him as Lucifer pokes at his bony sides.
"It's okay," Marie says, quietly. "Castiel said we'll get used to it." Lucifer turns his gaze to her. She doesn't flinch, but she doesn't look comfortable being the focus of his attention either.
"Get used to what?" Marie opens her mouth to tell him, but nothing comes out. She looks at the floor, frowning.
"I'm… not sure. He just said we'd get used to not having it." Lucifer wracks his brain. They're allowed to eat, even if they aren't eating enough, so what was Castiel- The horrible truth dawns on him, the hunger and loss reverberates in his own grace, and Lucifer understands exactly what's wrong. They have no Heaven. They have no other angels around them. They have nothing to draw power from, nothing but each other. No wonder they're starving. Lucifer would, if he wasn't an archangel, built to sustain himself even without Heaven.
Slowly, Lucifer widens the connection between the three of them. He lets a little of his grace pour down it, and he feels it be guzzled down greedily. Jack and Marie gasp in unison.
"Let me see your wings," Lucifer says. "I won't let you go hungry." Jack doesn't hesitate, caught up in the sudden quench of months long thirst. His wings all but explode into reality. They're a mess of tangled up and snapped feathers, but under the mess, they're white, matching the hue Lucifer's own once were but with shades of gold streaked throughout that are familiar enough to make Lucifer's heart ache. Lucifer can't help himself. He touches the underside of the right wing. It twitches back as Jack sucks in a breath. Lucifer stops, drawing back. "I'm sorry. It must be overwhelming. We'll get you acclimated to being touched first." He turns his gaze on Marie. "You too, little angel. Show me."
Up and over goes Marie's shirt, dragging her hair into more of a mess with it. Lucifer's gaze lingers on the sharp outline of her ribs. Her wings could just as easily have been mistaken for Lucifer's own as Jack's, though hers are filled with reds and pinks like a late sunset.
"You're both so beautiful," Lucifer murmurs.
They blush the same way.
Grief shadows his joy at seeing them. He's missed so much, and they've been forced to grow so fast. They have the wings of full-grown angels, the bodies of adults, and Lucifer wants nothing more than to cradle their tiny graces in his own and remind them that they are still his babies. "Get in the bath. We'll wash them off."
The rest of their clothes fall by the wayside. Lucifer watches with mingled concern for how thin they are and delight for how comfortable they are with him. He strips his own vessel nude and sinks into the water first. The heat is very relaxing. The twins enter slower, testing the temperature, dipping their toes into the water. Marie slides in first. Lucifer has never seen her smile so easily as she does when engulfed in the warm bathwater. Their wings cause great splashes as they move, sending water over the edge of the bath and into the surrounding room. Lucifer laughs.
"Marie, come here," he says. She wades over to him. Her hair is soaked dark with water. He cups her face, moving strands back out of the way, and he leans forward to kiss her forehead. He gifts a little grace to her through the contact. Marie shivers. "How does that feel?"
"Can I have more?" falls out of her mouth before she can repress it. She looks mortified up until Lucifer is kissing her again. He presses his lips to her temple, her eyebrows, her nose, her cheeks. Jack inches closer. Lucifer beckons him in so that he can hold Jack still and pepper him with kisses. They both sit in front of him, faces upturned and eyes closed, hungry for his affection. Lucifer has never been sure where humans draw the lines with this sort of thing, and he doesn't care too much. When his lips drift over Jack's, he kisses him there, too. Then Marie. Then Jack again. Back and forth, gentle kisses showering them both in love and spared grace.
It's a lot for the twins to experience all at once. They slump against him, exhausted from his attention. He wraps his arms around them and pulls them closer. Their wings splash in the water around them. Some of their broken feathers have fallen right out under the heat, drifting across the surface of the water. Jack snuggles against Lucifer's chest. Lucifer reaches out to stroke the arch of his wing. He shivers.
His feathers are soft and damp under Lucifer's hand. Lucifer runs his fingers through them to get them straightened out. He can hear Jack making quiet, content noises as he's pet, encouraging Lucifer to go on. He rubs his hand over Jack's wing, marking the path he then sinks his fingers down into
This time, Jack moans, and Marie stiffens. Lucifer doesn't stop. His wings needs to be groomed (and those noises sound so sweet coming from him.) Jack squirms, burying his face in Lucifer's chest. The longer Lucifer touches him, the louder he gets.
And then Marie whimpers, too. That does make Lucifer pause, only to check and make sure she's okay. Her pupils are blown wide, her wings spread open in the surrounding water like they're begging for touch, her cock hard between her legs. Compared to Jack's trembling, she's a statue. Lucifer looks between them. She must be able to feel a little of what Jack can from their bond. Lucifer drags his fingers down a sensitive patch of feathers and elicits a happy moan from Jack and a muffled gasp from Marie as she covers her mouth. That won't do at all.
"It's okay," he reassures, gently prying her hand away, still petting Jack with the other to keep him happy. "It's meant to feel good."
"Like sex?" she manages to ask between another gasp. Lucifer narrows his eyes.
"Have you had sex?" Marie flushes. Jack squirms.
"No," she lies, badly. Protective jealousy pulses in Lucifer's grace. She must feel it. "We were curious! All we did was try it out!" He tilts his head. We.
"You and Jack?" Marie nods. The jealousy settles immediately. That's more than okay. If they were with each other… they're both a part of him, so there's nothing that he doesn't get for himself. He leans over and kisses her temple. It's Marie who tips her head up, growing bold enough to ask for what she wants. Jack sits up to watch them kiss, to hear Marie moan into Lucifer's mouth in unison with him as his feathers are played with. He whines in the back of his throat. Lucifer can't deny him anything, turning to give Jack a kiss as well. He's slid up into Lucifer's lap, his clit rubbing against Lucifer's leg in little rolls of his hip.
Lucifer can imagine them together. Innocent as the first creations so long ago, filled with needs they didn't quite understand, fumbling until they found things that felt good. He can show them how to do it right. He can give them all the pleasure they want.
He wonders if making one of them come will work on the other. Only one way to find out. He pulls Jack closer, both hands sliding through his feathers. Jack cries out. It's wordless at first, but as Lucifer touches him, it becomes, "Mama! Mama, please!" The word sparks something deep inside Lucifer.
"That's it, let me give you what you need," Lucifer says. "Be a good boy for mama." Jack nods. His hand jumps out to clutch at Marie's. She isn't rubbing up against Lucifer like her brother, but from the way she's rocking her hips, she must want to badly. Lucifer has his job cut out for him teaching her to take what she wants. He licks his lips. That kiss showed progress.
He lets one hand fall from Jack's wings (preening them long since forgotten in favor of his orgasm) and between his legs. Jack's clit is swollen and throbbing against Lucifer's thumb. His other fingers slide deeper, probe his hole and sink inside, two at once. Jack rides his hand, lost in his own pleasure.
When he comes, he shakes all the way down to his wings.
Lucifer looks over at Marie. She hasn't come yet, though she looks desperately close. He takes note of that for later. For now, he lets Jack slump over, shifting to free his hands and help Marie out next. If he thought the noises they made were adorable before, they're nothing compared to the little whines of Jack as he's overstimulated by his twin's echoed pleasure and Marie's finally satisfied moan as he strokes her wings. "So pretty," he tells her, "you're both perfect. I'm never letting anyone take you away from me."
"Promise?" Jack mumbles. Lucifer kisses the crown of his head.
"They'd have to kill me first."
"We'd bring you back," Marie says. It's edged with a gasp as Lucifer finds her wing oil glands buried under her feathers and massages one. "We- Oh! Mama, we could- Together, we'd be able to-!" Lucifer's grace blankets both of theirs easily. He can see so much potential in them, so much strength, but not like this. They'll never be as strong as they should if they try to grow in these conditions.
Lucifer pets over Marie's ribs. He's going to feed them so well, until they're plump and healthy and never hungry again. He has more than enough to spare. With that thought, he opens the connection again, wider than before. Marie's eyes widen. Jack sucks in a breath. Lucifer lets them drink down as much grace as they need. They latch onto the flow, sharing it between themselves. It's not equal, he notices, Marie is trying to give the lion's share to Jack, but Lucifer pushes more her way to prove she doesn't need to ration it out. They're glowing, twin graces and souls lighting up from the inside out as they feed.
He reaches down to stroke Marie's cock. She finally gives in, thrusting into his hand and pressing closer.
"Good girl," he tells her. "Mama's gonna feed you. Don't worry." Jack scoots across Lucifer's lap to press against his twin's side, riding out the overwhelming sensations together. Their clasped hands are squeezed so tight, they might have broken a bone if they were human. Lucifer purrs. "I love you. My little nephilim. All mine." Marie comes, her cock spurting into the warm water. Lucifer strokes her through it.
And when they're both tired out from their orgasms and feeding off his grace, he's happier than he's been in a very, very long time. He glances down at his own hard cock. He can show them how to use that to make themselves feel good later. He leans back against the edge of the bath, a nephil under each arm, their wings cuddled together, and lets his mind wander through the possibilities.
