“You really wanna roleplay?” Lucifer asked, surprised at Alastor’s newfound boldness.
They’d been seeing each other officially for just over a year now, though unofficially they’d been fucking for a few months before they’d decided to become an item.
In that time, Lucifer had learnt things about Alastor he had never even considered. And Alastor had learnt things about him in turn. Most recently, he became fascinated with Lucifer’s ability to bend reality to his will.
“If that’s what you call it, yes.”
Alastor had swapped his monocle for a pair of glasses, lying in bed next to Lucifer as he pretended to read his latest book. It was some horror romance that Lucifer had come across on the latest summoning to the mortal world. He’d found it hilarious and had given it to Alastor mostly as a joke gift.
Lucifer knew he was pretending to read it from the fact he hadn’t turned the pages once since he opened the thing 20 minutes ago.
Asking for what he wanted was a big deal. Lucifer recognised how important that was for their relationship.
“Do you want to be a Doe?”
“No!” Alastor hissed, his head snapping so he could glare at Lucifer for his ridiculous question. “You aren’t to change me at all. Just yourself.”
“Okay.” Lucifer was laying on his stomach, a pillow under his chest so he could gaze at Alastor comfortably. “I need more details about what you want to happen. How do you see this playing out? Are we gonna lock antlers?”
Alastor’s mouth opened at what was the start of a protest. Then, his eyes became glazed, and Lucifer couldn’t help but smirk. Ok, antler locking was clearly a new kink. Lucifer could work with that.
“What if I just called you my Doe? Would you be into that?”
“No.”
Feminisation was off the table, also good to know. Sometimes Alastor didn’t mind it, but this was clearly one of those times it was a hard stop. They’d done a lot of hard work on getting Alastor to voice his boundaries before they were crossed, so moments like these made Lucifer’s chest swell with pride.
“Are you gonna prep beforehand?”
“Prep?”
Lucifer rolled his eyes playfully. “Al, you want me as a Buck. Which clearly means you want me to fuck your brains out. Are you gonna be stretched already, or do I gotta finger you open first?”
If Alastor was annoyed by Lucifer’s clarifying questions, the sexual nature of them was distracting enough that he could push the annoyance to the side.
“You’ll have to prepare me.”
“Praise or degradation?"
The adorable way Alastor chewed on his bottom lip had Lucifer’s tail curling under the covers. Whatever fantasy was playing out in Alastor’s head, Lucifer wanted to make it come true. Alastor so rarely asked.
“Degradation first, then praise.”
Lucifer slid his hand over Alastor’s thigh, giving it a squeeze. Alastor’s ears twitched a fraction lower as he flushed at the positive touch. So responsive, even after all of the time they’d spent together.
“When?”
The audible click of Alastor’s throat as he swallowed back a moan at the question had Lucifer’s horns pressing against his temple, begging to be released.
“Tomorrow night. In the Bayou.”
“We’ll use the traffic light system,” Lucifer confirmed, using his hand on Alastor’s knee as leverage to sit himself up, bringing them face to face. “Now come here, I want to taste you.”
-~-~-~
It turned out Alastor wanted a few very specific things from Lucifer. The full Deer look was one of them. Not that Lucifer minded; it was hardly the kinkiest change he’d made to his body to please a lover. The fluffy ears on top of his head were actually kind of cute. The fluffy tail was too, so similar to Alastor’s in size, yet so different in colour, matching his blond hair.
The only real difference between him and Alastor was the antlers.
Alastor had wanted them large.
Getting used to their weight had been weird, making Lucifer tumble a few times as he stalked around the Bayou. That was another thing Alastor had wanted. He’d asked for Lucifer to spend an hour or so just wandering through the area, leaving his scent around. If Lucifer understood it correctly, it was to rile up the animal side of Alastor into thinking there was an intruder. Which is why he wanted Lucifer’s antlers so naturally large.
They were going to have a brief fight, lock antlers, and then Lucifer was to overpower Alastor and fuck him senseless.
Whatever his sweet baby buck wanted.
Lucifer stopped at a pretty looking tree, full of swooping vines, and rubbed his antlers against the bark. Like many of the other trees he’d stopped at, his antlers gained some foliage, and a few of the vines tangled in them. When he was satisfied with how much he’d marked the tree, Lucifer stepped back, admiring his work.
“What are you doing?”
The question was loud, meant to make him startle. Lucifer didn’t fall for it, easily slipping into the character of cocky Buck.
“Marking up my new territory. Everything from here to the other side of the lake.”
“What?!”
Lucifer turned, purposefully dragging his gaze slowly over Alastor, down to his hooves, then back up to his antlers, where they lingered a moment too long. Just enough to make Alastor uncomfortable.
“You hard of hearing? Surprising with those big old ears of yours.”
Said ears twitched, flickering back to show Alastor’s rage, paired with his snarl. “This is my territory.”
“Please. I’d know if I was going over someone else’s marks. Either you’ve done a shit job in keeping up with them, or your itty bitty antlers just aren’t enough to get the job done.”
The jab hit its mark dead centre. Bullseye.
Alastor’s eye twitched with rage as he stalked closer to Lucifer, his antlers growing until they were the same height as Lucifer's. Which given their already stark height difference, really wasn’t that much. Alastor’s antlers looked tiny compared to Lucifer’s.
“So you’re a grower, not a shower. Big deal, kid. Your antlers are still itty bitty. Why don’t you go off and play house somewhere else, huh?”
Lucifer made to turn his back on Alastor, the ultimate ‘fuck you’, only he didn’t make it the full turn, Alastor’s claws digging into his shoulder and jerking him back around.
His eyes had turned fully black, pinpricks of red pupils staring at him wildly.
The scent of arousal was heavy in the air, though Lucifer pretended not to notice. Alastor had wanted a fight first, and Lucifer was going to give it to him.
Stepping into Alastor’s space, Lucifer barely exerted any power to shove Alastor back, making him stumble. “I said get lost, kid. I’m not fighting some pipsqueak like you. This place is mine.”
Alastor squared his shoulders as his head dipped, eyes locking with Lucifer’s through his bangs. It was a clear challenge, making Lucifer laugh.
Mimicking Alastor’s pose, Lucifer braced himself.
Alastor charged at him, the clash of their antlers sounding eerily similar to thunder. Their hands locked as Alastor attempted to brute force Lucifer into submitting. The way Alastor’s arms shook made his breath quicken and his pupils dilate. Lucifer was strong. He had always been much stronger than people gave him credit for.
Lucifer took a step closer to him, forcing Alastor to slide backwards in the mud of the Bayou.
The shaky moan Alastor let out was barely audible, though Lucifer’s ears flickered forward to pick it up all the same.
Oh, his pretty buck was loving this. Lucifer had always known that Alastor had a thing for power, he had just never assumed having power used against him was a turn on too.
Another step.
Despite how Alastor was desperately digging his heels into the ground, he slid just as easily as he had before. A twitch of Alastor’s antlers in an attempt to gain the upper hand gave him nothing more than a few petals falling loose from Lucifer’s.
“Are you going to submit?”
Alastor’s eyes narrowed. With a snarl, he jerked again, his neck cracking sickeningly as he tried again and again to shift Lucifer.
It didn’t work.
Lucifer tilted his head upwards, forcing Alastor to move with him, straightening him and bringing him closer in one smooth movement. The new leverage gave Lucifer the perfect opportunity, the black claws on his left hand clutching Alastor’s throat.
“Submit, or die.”
The grip Alastor had once had was gone, his claws slashing and swatting against Lucifer’s arm, trying to get free. When Lucifer squeezed the pretty gasping throat, Alastor made a sound he’d never heard before.
It was a panicked animal sound.
Alastor’s hands were gripping Lucifer’s wrist now, their eyes and their antlers still locked.
“No respect for those above you, little one? I have a way to teach you…”
Alastor’s eyes glazed over.
The drop into subspace was quick, all fight leaving Alastor’s body as he let Lucifer’s hold against his neck be his pillar of support.
Carefully, Lucifer untangled their antlers.
As soon as they were free, Lucifer gripped Alastor by his antlers, hand leaving his throat so he could turn him, pushing him into the bark of the tree he’d marked up only minutes before.
When the broken bark cut open Alastor’s cheek, he moaned, back arching to present himself to Lucifer, tail wagging against his back.
“You like that, huh?” Lucifer pulled Alastor’s head back, his free hand pressed between Alastor’s shoulder blades to keep him mostly against the tree. He licked up the blood from the side of Alastor’s face, making the buck whimper. “I bet you do this all the time, challenge other bucks until they put you in your place. Pretty thing like you shouldn't have to fight. You should be on your knees, begging for me.”
“Yesss.”
“Colour.”
“Green. Green.”
The affirmation had Lucifer fighting his smile into a smirk. Alastor didn’t want kindness. Not yet. He wanted to be dominated, and he wanted Lucifer to do it roughly.
“Hands on the tree, little buck.”
Alastor complied. When Lucifer’s hand left the middle of Alastor’s back it didn’t go far, sliding under Alastor to start undoing the buttons of his shirt. Thankfully, he’d foregone the jacket and harness, probably concerned that Lucifer would rip them. In all fairness, that had happened. Once. Lucifer took extra care with Alastor’s clothes after that particular meltdown.
Once the shirt was fully undone, Lucifer’s fingers tangled in the fur across Alastor’s chest. Lucifer pulled, and Alastor responded with a high-pitched keen from the back of his throat. When the pain got to be too much, Lucifer stopped, his claws slipping lower under they met with Alastor’s second set of nipples, brushing over them playfully. Alastor’s stomach clenched under his touch, trying to get away from Lucifer’s claws with no success.
When Lucifer had first discovered them he hadn’t been sure what to think. Now though, they were one of his favourite parts of Alastor to tease.
“So sensitive.” Lucifer nudged his head against Alastor’s back, his antlers laying against Alastor’s shoulders. Like this, they were marking the tree together, Alastor’s new gouges deep, with Lucifer’s light. “Do you play with them yourself, little buck?” Lucifer asked, trailing lower to his final set, just above his hips. The scraping of Alastor’s antlers against the tree was drowned out by the sound of his moan.
Next on his war path were Alastor’s trousers. Lucifer had perfected the one-handed removal technique, thumbing open the button and pushing down the zipper.
“Fuck, no underwear? Were you expecting me to bend you over and fuck you?” Alastor didn’t respond. He didn’t need to, when Lucifer gripped him he was already hard. “I was right, wasn’t I? You’re just whoring yourself around to whatever bucks you can find.” Lucifer squeezed him, just on the wrong side of painful. “Sorry, pretty baby, I don’t work that way. If I’m fucking you, you’re mine. You belong to me. Your only job is to keep my bed warm.”
Alastor’s cock twitched in his hand, the high-pitched keening noise back.
“That what you want? You wanna be my mate, little buck?”
“Yes! Yes!”
Lucifer was pretty sure he blacked out for a second, coming back to his senses with his mouth latched onto the back of Alastor’s neck, teeth embedded in the soft skin there. Alastor was crying, fat droplets of tears streaming down his face. Lucifer’s let go of Alastor’s spent cock, forcing his jaw open so he could release Alastor from his aggressive bite. Without his teeth holding Alastor up, the demon collapsed against the tree, his antlers dragging down the bark like desperate claw marks until he was on his knees.
Wiping his mouth with the back of his hand, Lucifer leaned against the tree, looking over Alastor.
“Colour.”
“Green.” Alastor whimpered, turning his head so he could look up at Lucifer through his clumped eyelashes. Shoving at his trousers, Lucifer pulled out his own hard cock, thumbing over the leaking head.
“You look so pretty when you cry,” Lucifer said with a touch of sincerity. “Open your mouth, there’s a good boy.”
Alastor obeyed, ever eager to please now that his own pleasure had been achieved, even going as far to stick out his tongue, eyeing Lucifer’s cock like a man starved. Lucifer changed his hold from the tree back to Alastor’s antlers, tugging his head as he stroked himself. It wasn’t long until he was coming across Alastor’s face, marking him up.
It was one of Alastor’s favourite things, being marked up. Bites, bruises, come. It didn’t matter what it was, as long as it was a physical reminder of who Alastor belonged to.
Scene over, and Alastor was pressing his face against Lucifer’s thigh, the occasional shiver wracking his body. Lucifer pet through Alastor’s hair, transforming himself back to his usual self so his tail could wrap comfortingly around Alastor’s neck, giving it a little squeeze.
“Thank you.”
“You don’t need to thank me, Al. You did such a good job.” Lucifer praised, watching as Alastor closed his eyes to nuzzle at him some more. The plan had been to fuck Al senseless, but Lucifer’s urge to bite him had been too strong to ignore. He’d just have to save the fucking for another day.
