Bikini Bottom

Summary:

"Charlie asked me to grab you. Didn't think I'd be the subject of some stripper tease show, though," the demon teased, inching closer, towering over Lucifer. She felt the tinge of sweat forming on her brow, and Lucifer ducked away from Alastor's hovering to readjust her bikini. Her face continued to shine with a bright hue.

"J-Just give me a minute," Lucifer stuttered, turning around from Alastor to fix the shoulder straps on the bikini. Since the garment was on the smaller side, the pads covering her boobs were a little too small for comfort, and any kind of harsh movement would move them from what they cover. Maybe she should just change into the duck one and deal with a day of humiliation.


Charlie invites Lucifer out for some daughter-daughter pool time. Lucifer has to find what bikini to wear. Alastor has some opinions on the matter.

Work Text:

Lucifer couldn't believe she actually agreed to spend the day at the pool with everyone at the hotel. Spending the rest of her afternoon with a bunch of people she doesn't remember the names of sounds like a fucking punishment, but when she saw the look on Charlie's face—pleading eyes and puffy lips—Lucifer couldn't help but agree.

Now she had begrudingly agreed to tan with her daughter in the hellish sun, even though their white skin burns really fucking easily. Tanning with Charlie wouldn't even be that bad if it were just the two of them, including the girlfriend. God, she can never remember her name. Haggie? Vagerie?

Shit. It doesn't matter.

One of the main reasons she doesn't want to spend time at the pool is because of her body.

Back when Lucifer was married to Lilith, she would always dominate the physical setting. Tall and blonde with smooth, porcelain skin that was perfect without even needing to care for it. Lilith had nice features, too. Especially her ass and chest. Lucifer felt herself constantly comparing to the latter, eating smaller portions and healthier options to barely get to where Lilith was at.

And it's not like Lucifer doesn't have some nice features. Her chest is on the slightly bigger side than most. Like...a C cup? Is that what humans refer to as the sizes? Eh, it doesn't matter. But she's decently built down there, too, but really, both aspects only show off in tight gala dresses when Lucifer goes to parties with the Sins.

Another reason Lucifer isn't pumped for hanging out is that the pool day includes all of the guests. All of the guests means Alastor will be there, and she is so fucking irritating. Like, how can someone be so aggravating to the point where they are engraved into said person's brain? Her perfectly kept wavy bob and form-fitting clothes messed with Lucifer's head, and not in a good way.

Lucifer groaned, running a hand through her long, blonde strands, expecting to deal with the ridicule that would come with the attire she was wearing at the pool. Right now, she was laying out all of the options for the pool, and Lucifer realized she only had two kinds of bikinis. One of them was a duck-themed triangle bikini, which was yellow and pink, and the other one was a somewhat small maroon string bikini that was gifted to her from Lilith. The string bikini was never worn before.

The question becomes, does she humiliate herself in front of Alastor by wearing the duck bikini? Or does she wear the maroon bikini and suffer through depressive, vivid flashbacks of her past relationship with Lilith?

The time on the duck clock in her room struck 1:00 PM, signifying her lateness.

"Shit, shit. Charlie's going to be waiting!" Lucifer cursed out loud to herself, grabbing both bikinis and heading to her closet.

Lucifer stripped her pajamas and slipped on the maroon bikini. The string around her hip felt like it was showing off too much skin, and Lucifer visibly flushed. How could she ever wear this in public? Lucifer turned side to side in the mirror, and she noticed how the string and V-form of the bottom actually made her curves look good.

"Maybe I'll try the top...," she hesitantly stated as she removed her shirt.

Just as Lucifer began tying the bikini around her back, there was a knock on her door. She ignored it, twisting her body to try to tie the stupid top properly. It was most likely Charlie at the door anyway, since they were supposed to walk down together.

Each time Lucifer tried to tie the top, it would unravel. "Fucking hell, I should've just tried on the duck bikini first," she cursed to herself.

The knock at her door persisted, growing more urgent. The string still wouldn't properly tie itself, and Lucifer threw her hands up in the air in frustration. Instead, she wrapped the string around her back and then around her underboob as a makeshift hold as she went to answer the door. Maybe she'll ask Charlie to help her, but Lucifer knows her pride would never allow that to happen.

The knocking grew annoyingly persistent, and Lucifer was about to yell at Charlie for the incessant pounding.

"Holy shit. Charlie, relax, I'm on the way," Lucifer yelled as she reached for the doorknob. Pushing her blonde hair back, feeling it hit her ass, she opened the door.

Rather than his darling daughter at the door, Lucifer was met with a relatively annoyed radio demon. The said demon was wearing a black robe, where Lucifer could make out the faint lines of a cherry-red monokini one-piece. It looked hot. No, no. Not hot. It looked form-fitting.

Lucifer was stunned, staring up at Alastor as she was revealing more skin than she would've ever expected to see from her.

Alastor looked down, ears straightening in response. Lucifer noticed Alastor staring right in the middle of her cleavage.

"Your...uhm...," Alastor pointed to the middle of her own boob right where her areola should be. Lucifer raised an eyebrow, then looked at her own, where the bikini top was slanted, revealing her bare boob in front of Alastor. A bright golden flush came across her cheeks, and she rushed both hands to cover her chest. Alastor chuckled, walking into the room and closing the door.

"Charlie asked me to grab you. Didn't think I'd be the subject of some stripper tease show, though," the demon teased, inching closer, towering over Lucifer. She felt the tinge of sweat forming on her brow, and Lucifer ducked away from Alastor's hovering to readjust her bikini. Her face continued to shine with a bright hue.

"J-Just give me a minute," Lucifer stuttered, turning around from Alastor to fix the shoulder straps on the bikini. Since the garment was on the smaller side, the pads covering her boobs were a little too small for comfort, and any kind of harsh movement would move them from what they cover. Maybe she should just change into the duck one and deal with a day of humiliation.

"Stupid fucking straps," she cursed under her breath.

"Putting on a show for me, too?" Alastor sauntered over, standing menacingly behind Lucifer.

Lucifer stopped, swallowing a lump in her throat. She kept on taking in gulps as her mouth suddenly felt dry. Her body shivered, Alastor’s shadow consuming her own.

“Shut up, Alastor,” she mocked, missing the intimidating mark. Her voice trembled ever so slightly. “Could you back up?” Lucifer turned her head barely and was met with a lidded gaze from the demon.

Alastor hummed, walking further into Lucifer’s back as she shuffled forward to get more space between them.

“Hey, could you back—“

“If I’d known I’d see you like this today, I would’ve agreed to the pool day sooner.”

Lucifer stopped in her tracks—back still facing Alastor. Did she just hear what she thinks she heard?

Behind Lucifer, she could hear the noise of cloth slipping down skin, and she realized Alastor untied the black robe she was wearing. A nervous gulp left her lips.

“W-What are you doing?” Lucifer asked, still clutching onto the front of her top.

“Relax, Luci. You need help tying your swimsuit, right?” Alastor leaned in, breasts pressing against her back.

“I mean…y-yeah,” Lucifer wrapped her arm across her chest, running a shaky hand through her hair. She felt incredibly nervous, but also weirdly excited. It’s been a while since anyone’s touched her, but this felt weirdly perverted

And Lucifer felt like a slut for enjoying the attention.

Slowly, Alastor trailed her claws across the straps along her shoulder, sending shivers up Lucifer’s spine. The devil arched slightly, ass pressed against Alastor’s thighs. A chuckle came from the demon, and she continued to tap lightly on her arms.

“My, quite excited aren’t we?” Alastor’s hands trailed from the top of her collarbone down to the tips of her elbows, bringing the bikini straps along with them.

Lucifer felt her boobs fall from the lack of weight holding them up, and whimpered into the touch. Alastor continued to tease, rubbing up and down using the tips of her claws. Each contact with her skin sent an all too familiar tingling sensation in her pussy.

God, she wanted Alastor to touch her there.

“Stop teasing!” she whined, shooting a murderous glare behind.

Alastor chuckled, unraveling the somewhat tied portion of the bikini around Lucifer’s midsection. The action caused her to moan meekly, causing Alastor’s ears to straighten.

“So reactive! I wonder how loud you can get just from minimal touching.”

As she pulled down the rest of her bikini, revealing her bare chest to the world, one hand snaked to grope Lucifer’s ass.

“Ah!” Lucifer gasped, not used to the feeling of someone grabbing from back there.

“Fucking hell. Your ass is perfect for my hand,” Alastor fondled her cheek, squeezing hard, “Do you know how hot you look in this bikini?”

Lucifer whimpered, arching further into Alastor’s grasp.

“Parading around in a swimsuit barely covering anything. Like a little slut begging to be used.”

Alastor leaned in, continuing to whisper dirty things into her ears. Lucifer shook her head while letting out obscene sounds. Being degraded by Alastor was something she didn’t think she would be into.

“I didn’t mean to!” Lucifer turned around, hair falling over her chest. Alastor released her grip, resting both hands on the devil’s hips, fingers lacing between the strings. She twirled her fingers around the cloth, loosening the tightness that kept up Lucifer's bottom.

The devil stared up at Alastor, blushing furiously. She sheepishly covered her chest with her arms while Alastor played with the bikini bottom's ties. Half-lidded eyes bored into her yellow ones, breath ragged. Lucifer closed her thighs together, attempting to isolate the wetness that was forming in her crotch.

Shit. She was practically leaking.

Lucifer prayed Alastor wouldn't notice as she continued to tease her skin with the grip on her ties lightly.

The red-headed demon leaned in to whisper into Lucifer's ear. Alastor's fur tickled against her pale skin, and Lucifer shivered in response. As she whispered dirty things into her ear, Alastor's claws moved to strip her bikini bottom all the way down.

"I'm going to fuck you on my fingers until you're begging for me to stop."

Alastor's canines nibbled on her ear, sending another round of the same pleasurable, tingling sensation throughout Lucifer's body.

"I'm going to leave marks all over you so the whole staff knows who you belong to."

Another glob of her fluid sat in her bikini panties, causing the whole room to feel warm. Fuck, she was really getting turned on.

"Fucking hell, if I could, I'd fuck you silly until you're swollen with another kid."

The comment threw Lucifer off guard, and she opened her mouth to reply to the statement, but suddenly Alastor's horns started growing atop her head.

Her grip tightened, fingers untying the string to let the garment fall swiftly to the ground. Lucifer's bare pussy fell upon Alastor's lidded gaze, wet slick sticking shamelessly to her thighs. She whimpered, a timid hand coming up to cover her face in embarrassment. How was she so wet just from dirty talk and teasing? Has she been out of the game for that long?

Alastor's breath hitched, and she dug her claws deeper into Lucifer's sides. The action made Lucifer yelp, effectively jumping in the air for the demon to hold. Alastor held her in a bridal carry, taking both of them to the bed. She was still wearing her bikini, but given the situation, it was likely to be removed soon.

As she lay her down on the sheets, Lucifer grabbed a pillow to hide her chest while closing her thighs together to cover up the leakage residing on her thighs and hole. Alastor rested on her knees, beginning to strip the rather sexy one-piece she was wearing. Lucifer couldn't help but stare at her figure.

Her breasts were fucking huge. Like, Lucifer knew this, but actually seeing them free without anything holding or covering them was a sight to behold. There was a healed scar across her chest, and it was most likely why Alastor always wears multiple layers. Then there was her torso. There was enough curve to where it perfectly complemented the absolute ass she carried. To top it all off, she was incredibly tall, and her towering figure completely enveloped Lucifer.

Lucifer imagined Alastor hunched over her, long, thick claws reaching in places Lilith could never go. Then she'd fuck her silly while grinding their clits together. Lucifer would orgasm tenfold while crying into the sheets.

Her shaky hand reached down to palm herself, two fingers beginning to rub circles against her damp clit. Lucifer's legs impusively widened, pussy throbbing. From hiding slightly underneath the pillow, she could hear a breath hitch in front of her. Lucifer moaned, continuing to imagine the sexual acts Alastor promised.

Walking down in her revealing bikini with deep, yellowish bruises across her skin and fucked up hair—she couldn't help but gasp. Lucifer whimpered into the satin case, keeping the same pace against her clit. The bed dipped slightly, and Alastor leaned down to stare. It was like a predator stalking its prey.

A possessive grip stopped her from continuing to pleasure herself, and Lucifer whimpered at the loss. She was getting so close.

"You're mine, and you finish from my doing," Alastor warned, grabbing the pillow that she was using to cover herself and throwing it across the room. Lucifer gawked, another flush of golden spreading across her cheeks. She was completely bare underneath Alastor's gaze, and couldn't help but turn away from embarrassment.

"S-Stop saying things like that," Lucifer covered her face with her arm, turning to the side to avoid the look on Alastor's face.

With a hum of acknowledgement, Alastor nestled herself between Lucifer's thighs. The familiar feeling of her claws trailed up them, and she instinctively flinched. They were cool to the touch. Lucifer arched into it, noises slipping from her puffy lips. The coldness conflicted with her warm thighs, and Lucifer didn't know how to feel.

As the hand trailed up to her wet heat, Alastor leaned down so her head nestled between her thighs as well. Lucifer flinched at the fur prickling her skin.

Lucifer looked down and watched as Alastor pushed her legs further apart. Her opening was on full display, slick flowing barely to stain the sheets. Alastor let out a hot breath against it, her body shivering with complete want in response. Lucifer's mind was unraveling, and all she wanted was to get off and get bent properly.

Alastor answered her thoughts, apparently, because she poked her vagina with one of her fingers. A startled gasp fell from her lips as the tip of the demon's finger entered her slippery walls. Lucifer whimpered as the long, thick claw slid deeper inside of her. Whimpers turned to moans as the finger just kept on going. It wiggled slightly, applying pressure inside her pelvic bone. It felt like a harsh pressure on her bladder. Fuck, she better not piss herself on accident because of this.

"So loud. Better be quiet, Lucifer," her ears flicked at each sinful moan that left Lucifer's lips. When her finger went as deep as it could go without pushing through her cervix, Alastor leaned forward to rest her mouth on Lucifer's thighs.

"F-Fuck, is that just one f-finger?" tears bridged the corners of her eyes, and her insides naturally clenched around the intrusion. Even though Lucifer couldn't see it, she could feel the smirk from Alastor against her thighs.

Instead of responding to her comment, Alastor gave a soft kiss to the section of her thighs right next to her lips. Lucifer's body flinched at the sensation, legs quivering slightly. Her legs acted on their own and tightened together. Alastor hissed in disappointment, poking up against her walls with the finger deep-seated inside.

"Fuck! A-Alastor!" Lucifer whined, arching her back at the prodding. It felt like she was fucking her directly on her clit. The pleasure inside was so good she couldn't even think straight.

Alastor responded by biting down—hard. Sharp teeth sank into her thigh, causing Lucifer to writhe around in pain. Her legs acted on their own, kicking instinctively to remove the pain shooting up through her nerves. Golden, warm blood trickled down her thighs, and Lucifer couldn't help but let out pathetic whimpers as she was held down by Alastor's bite.

After a couple more seconds, the demon released with a loud pop, blood sticking to her lips. Alastor licked them, humming from the taste, and diving back to the other side of her thigh to give a matching mark.

Lucifer felt her legs convulse without reason. Alastor continued to poke with her finger while digging deeper into her thigh. The combination of senses fucked with her brain, and random noises escaped her mouth instead of intelligible words.

The constant assault on her senses started bringing back the beginnings of her orgasm. If Alastor continued doing what she was doing, Lucifer would finish rather quickly.

"You taste so good. I want to drink you up," Alastor's hot breath settled against her gaping bite wounds, and the demon sat up slightly to add another finger inside. Lucifer let out a slutty moan she didn't think she could ever make. The feeling of another long, thick claw going inside of her sent sparks throughout her vision. Fuck, she's going to black out.

"Keep going, please," Lucifer begged, shaky hand reaching to grip a chunk of Alastor's hair. The demon obliged, pulling her fingers back out—leaving Lucifer pulsating with need—before slamming the digits back in. Each thrust inside poked far inside of her vagina, and if she pressed against her abdomen hard enough, their fingers could probably meet against skin.

"Alastor, please don't s-stop. I wanna finish so badly," Lucifer arched at a particularly harsh thrust.

"If you say so kindly, Luci," Alastor chuckled, thumb snaking around her labia to settle against her aching clit, setting a steady pace. Lucifer screamed, body twitching with absolute need. Everything felt so good. The pressure, the stimulation, the biting—all of it was clouding her brain.

The demon leaned over, fingers still playing with her pussy, and began to nibble on her hips. Lucifer struggled under the marks, body flailing from the pain. She wanted to escape, but the idea of being marked head to toe by the radio demon cemented her in the spot, taking all of Alastor's playings.

After she was done leaving marks on her sides, the demon moved to bite Lucifer's perky breasts.

"Don't mark those!" Lucifer screeched, using her hands to push Alastor's head away from her chest. Her ears flicked in annoyance, and she stopped stimulating her clit. "Wait—"

Alastor began furiously fucking her walls with her fingers, pulling out and slamming back in at a ruthless pace. The actions were so harsh that Lucifer felt herself inching farther up into the headboard. Each thrust felt so unbelievably good, and Lucifer could've finished right then and there, but all she needed was a little more. Just—shit. Fuck. She was so close.

"Alastor, can you go back to the rubbing? Please?" Lucifer begged, sitting up on shaky arms to stare into Alastor's eyes. She rolled her eyes, continuing to finger her brain out.

The demon stretched herself to rest her face in the crevice between her boobs, rubbing her cheek against them. She eyed them, opening her mouth to show off the sharp canines that were digging in her thighs earlier. Blood still stained the tips of her teeth. Lucifer knew what she needed to agree to if she wanted to finish.

Lucifer choked on the pleasure that came from an angled thrust, and she nodded furiously to agree to Alastor's demands.

It was followed by a deep bite on the underside of her right boob, and the thumb went back to its pleasuring pace. Filthy moans filled the room, and Lucifer chased her own pleasure by grinding in pace with the circles around her clit. Alastor moved to the other boob, sending another sickening bite to it. With Lucifer's angelic healing, they would bruise over easily, with the only remnants being the blood stains on her skin.

It only took a couple more grinds before Lucifer felt the peak of her orgasm.

"Alastor!" she moaned with a cry, legs trembling against Alastor's body. Her fingers kept on going, and Lucifer felt the overstimulation hitting. With pleading moans, Lucifer tried to inch away from the onslaught of sensations. Alastor caught on and slowed her pace, leaving petite kisses along her belly.

"So fucking hot," Alastor whispered, removing her fingers, followed by a loud squelching noise.

Lucifer whimpered at the loss, her pussy still vibrating from the remnants of her orgasm. She tightened her legs together, sitting up against the headboard to look at Alastor. The demon wiped the stickiness on her fingers on the sheets, ears down with content. They were silent for a bit as the heat of their coupling settled.

She pushed a strand of hair back and brought her knees up to her chest. Lucifer was still naked, too.

The reality of what had just happened hit, and Lucifer began to panic internally. She just had really fucking hot sex with Alastor. The demon also littered her whole body with very obvious bite marks. How the fuck was she going to tan with Charlie now? She can't even leave the room anymore.

"Stop thinking, Lucifer. Nobody's going to care if you're not there."

She was brought back from her thoughts and turned to look up at Alastor. The demon was still very much bare, turned to the side while showing off her very smooth and furry legs.

"S-Sorry," Lucifer stuttered, feeling embarrassed. Without the tension of their sexual play, everything was just awkward. Alastor sensed this and scooted closer to settle next to Lucifer. She stared into her pale skin.

"We can just ditch the pool day and...," the demon traced her claw lightly down her boob. Lucifer's breath hitched, and her cheeks warmed up. The thought of another round of insanely good sex enticed her, and she couldn't think of any reasons to say no.

"Okay," Lucifer hesitantly agreed and felt Alastor push her back down into the sheets. It was going to be a long day.
