The air was filled with heavy breathing and the unmistakable sound of lewd squishing, the inevitable result of the angel and the demon meeting in the church.
That they had come together there was telling, and even before she had set foot in the ancient building, Danika had known one thing for sure.
Tonight, the angel would be in charge.
They were sisters, of a kind – a pair, one dark and one light, one crimson-skinned and amethyst-eyed, and one with flesh as white as cream and eyes the colour of sapphires. Yet unlike most sisters, theirs was a relationship that revolved around the wanton indulgence in mind-bending sex. Being part of the heavenly and infernal hosts had its perks, after all.
Their nubile bodies were slender, lithe, wickedly curved at the hips, breasts, and buttocks with the sort of softness that blessed the youthful figure of the eternal college senior, giving them something to hold on to, something to slap, something to squeeze between eager fingers. Luscious hair spilled down their shoulders, the angel's a golden cascade with two braids circled around her head like a crown, the demon's a wild tangle of glossy jet. Full lips were as easily given to a smirk as a pout, the angel's rosy pink at odds with the blackberry purple that framed the demon's lazy, easy smiles. They would have been the same height but for the pair of black horns that swept up and back from Danika's hairline giving her the edge, their pointed tips curling around like those of a ram and capped with ferrules of gleaming gold. The only other difference between the two sisters, aside from colouration and cornification, was the ring that pierced the demon's septum, a glint of dark gold below a nose exactly as demurely pert as her sister's, resting in exactly the same place on her fine-boned, sharp-jawed face.
The demon had answered Lariel's summons, shedding her stockings and corset obediently at the heavy door to the church, the naked walk to the altar a sacred part of their ritual whenever they met in this place. When she had reached the great stone table her sister had done the same, loosening her dress of shimmering white at the shoulder with a smirk. A thrill of excitement had passed through the demon when when it had whispered over her sister's breasts, the fabric hesitantly clinging to something that distinctly bulged as it fell past her thighs, and her breath caught in her throat as she saw that her sister had taken a fancy to having a cock this time.
Last time they had met, in a darkened room in a particular type of late evening club, she had spent hours between Lariel's legs, parting her petals with her tongue, tickling her through climax after climax as the angel had thrown her head back and ground her pussy against Danika's mouth.
This time, she had felt her own pussy moisten at the mere sight of her sister's semi-hard shaft, its meaty length and girth at odds with its femininely curved owner, knowing full well what the angel was capable of doing to her with it. She had almost sank down to her knees to greet the lazy ivory rod with a kiss, only to be sharply jerked to her feet by the fist that had grabbed a handful of her hair and pulled upwards.
"Not even a word of greeting for your dear sister," Lariel had murmured in a sultry voice, planting her mouth on Danika's in a hot, wet kiss. "I should punish you for that."
Danika had moaned into her sister's mouth, knowing for certain that her sister was in one of those moods, that whatever else happened she would leave the hallowed ground shaking and deliciously sore.
Minutes later, she she was moaning around her sister's fingers as the angel left no doubt in her mind that she was indeed in one of those moods.
One pale hand squelched between the demon's legs, fingers slick with infernal pussy juices that dripped onto the cold flagstones beneath, and the other was firmly lodged in the demon's open mouth, clamping down on her tongue like a vice, shaking her head like a puppet as Danika's eyes rolled back and drool spilled over the angel's steely grip on her jaw. Lariel knew how easy it was to use her sister's sensitive pussy to send the demon into bliss, and delighted in taking full advantage of that fact.
"You fucking slut," the angel purred in wicked, honeyed tones. "Look at you, leaking all over my floor like some greedy college whore. Does the thought of my cock turn you on that much?"
"Guh...yesh..." the demon choked from around the angel's invading digits. She was barely able to keep herself standing, let alone formulate coherent words as the angel plundered her dripping slit.
"You'd better enjoy this then. It's all your pussy will be getting tonight." The angel didn't need to say any more – Danika had already translated it into I'm going to fuck your mouth and break your ass.
"Ungh..."
Lariel pulled her hand from the demon's mouth to slap her hard across the face, and when Danika's head whipped back around to face her, her violet eyes were wide with excitement.
"I've missed you, sister."
"You'll miss me even more by the time I'm done with you tonight," the angel replied smugly. "You'll be begging to transfer over to my side."
"Or maybe you'll decide that you want to trade in clouds for flames."
"We're in my house now," she reminded the demon, pressing her thumb down hard on her sister's clit to draw out a sharp gasp from her. "Maybe I'll just keep you here forever, my little demon slave that I'll share with all the others. Maybe I'll chain you to that altar and leave you there for anyone who wants their cock sucking. Or their ass tonguing. Angels are nastier than people think."
At her words, Lariel felt her sister's slit get even wetter, and she chuckled to herself. The demon was a sucker for being dominated.
"I'm yours, sister," Danika said breathily. "Take me however you want."
The angel made a low sound of appreciation, tracing a wet finger down the line of her sister's neck.
Danika knew exactly what she wanted.
She reluctantly let her sister's fingers slide out of her pussy and lifted herself to sit on the edge of the altar, kicking her legs girlishly against the side. By day, the stone table was the site of veneration, of honest worship, but on those nights when the church was empty save for the two sisters...the angel smiled darkly to herself. If only they knew the depraved acts that had taken place atop that altar. She drew their lips into a kiss, her cockhead pressing into the demon's navel, stiffening at the touch of her sister's smooth skin. Then the demon spun around, lying on her back so her head was hanging just over the edge of the altar, one leg bent at the knee. Her world was suddenly dominated by the ivory pillar that reared up in front of her, a twitching tower of meat just waiting to be coated with her throat slime, and the balls that hung ominously below it.
The demon breathed in deeply, drawing in the heavy, earthy scent of the angel's cock, the pungent odour of precum at odds with her radiant appearance as one of the heavenly host. She drank in the base, animal scent, her slit glistening in turn, and one hand crept between her legs as the other reached out to stroke her sister.
"God, that's so good..."
Lariel tapped her finger stiffly against the demon's chin, and smirked down at her crimson sister.
"We'll have enough of that language in here."
The demon giggled, running her tongue along the underside of the beast in her hand, and went to pull it down to slide the tip into her mouth.
"So greedy!" the angel said, twitching her cock to send it jumping out of her sister's grasp, bouncing above her eager lips. "If you want my cock, you've got to earn it first." She reached between her legs, tightening her fingers into a ring to make her heavy balls bulge in their pouch.
"Mmm..." the demon hummed, her eyes locked on the heavy cum-factories, her tongue flickering over her lips. "I can do that."
Lariel leaned forwards to dip her balls into the demon's wet mouth, lips parted to form an inviting hole. Danika took them with ease, both orbs disappearing between dark lips, her tongue immediately lapping at them, bathing them in saliva, gently probing and poking. The angel groaned as her balls were spit-shined, her cock throbbing in her sister's grip as she slowly jerked the thick rod. Red fingers striped her pale shaft like an obscene barber's pole, crowned with a spongy dome the same pink as her lips.
Danika's cheeks hollowed as she sucked on her sister's balls, massaging them with flat strokes of her tongue, tickling them with the point, playing with them as though she could coax more cum to churn in them. She swirled them around in her mouth like a fine wine, lavishing adoration on them, trying to give her sister pleasure solely from her tongue and the insides of her cheeks. All the while she kept touching herself, wet clicking sounds drifting into the air from the attention being paid to both sisters' nethers. Her nose was filled with the warm musk of her sister's cock and balls, filling her mind with a heady haze.
Then suddenly Lariel's balls were pulled from her mouth with a pop, and her cock slipped past her fingers, falling to bounce from Danika's cheeks.
"Hey! I was enjoying those," the demon said, her voice mock-petulant.
"Oh, I think I've got something that you'll enjoy more," the angel replied huskily, pulling her hand down her shaft to stretch her foreskin tightly back, her dome visibly throbbing. She tapped her cock against the demon's lips, a battering ram demanding entry.
Danika wordlessly opened her mouth, unable to make eye contact with her sister but knowing that if she could, that Lariel's cerulean eyes would be smoked with lust. The unmistakable texture of the angel's domed crown slipped past her lips and into her mouth, and the angel drove her cock firmly into Danika's throat, slipping into her tight passage with only the slightest resistance. The demon gagged, willingly surrendering her ability to breathe in order to pleasure her sister's rigid shaft. Her throat bulged lewdly out, accommodating the most welcome invader into its depths.
Lariel reached down to sink her fingers into the demon's crimson titflesh, feeling her dark nipples stiffen beneath her palms. A muffled moan slipped past the eight inches of cock currently lodged in her sister's throat, vibrating her thanks along her length as Lariel massaged her sister's chest. The hand between the demon's legs left her slit for a moment, and Lariel grabbed her wrist to trail her tongue along her sister's fingers, glistening with sticky pussy juices. They tasted each other, one groaning around the salty meat that pressed against every one of her tastebuds, the other purring at the sweet flavour of arousal.
"That's got me going now..." the angel murmured, pushing deeper until the demon's lips were stretched wide and her vision was blacked out by the slimy balls that came to rest on her forehead. Lariel groaned as her cock was massaged by the tight rings of muscle in her sister's throat, hilting her white meat fully in Danika's oesophagus. Lariel began to rock her hips, settling into the rhythm of a slow, short-range throatfucking, pulling her cock out a few inches only to press it back in, her balls beating out a sticky rhythm against her sister's face. Danika choked and gagged on the thick meat desecrating her gullet, awful sounds filling the air as her sister bred her face, her cock sliding in and out as though it were plunging into the demon's pussy.
"Look at that bulge," Lariel purred, wrapping both hands around Danika's throat as it distended obscenely around its girthy invader, the outline of her cock pressing outwards against her fingers with every thrust. The demon stroked her arm, giving her full permission to choke her, to use her as a sleeve to pleasure her angelic rod. Lariel picked up her pace, moving faster, harder, until she was hammering her sister's face like a sex-starved salaryman in a seedy brothel.
Lariel loved to feel her sister's throat massaging her thick meat – the demon loved it too, to let herself be used as a sloppy, spit-covered hole, to surrender her throat to pulse around the heavenly shaft. Danika could hear her lips squishing against the angel's base with every thrust, her mouth stretched into a wet O by the hard meat sliding over her tongue. She took her pounding with delight, feeling the ache in her lips as they were stretched and bruised, rubbing her clit until she shivered her way through a miniature orgasm. Her eyes watered, her world now consisting of only the lewd distension of her throat and the hard, fast rhythm of her sister's heavy balls slapping against her nose.
The demon felt Lariel's finger tighten around her throat, and she knew that her sister was teetering on the edge or her own orgasm. She pulled her hand from between her legs, reaching up to trace small circles around her dark areolae, squeezing her breasts and squirming helplessly to give her sister a show. The pressure around her throat increased, and she would have smiled if it weren't for the cock forcing her mouth wide.
"Oh, I'm going to fucking cum!" Lariel yelled, not once slowing down in her brutal assault of the demon's gullet. Danika moaned beneath her, eager for her sister's seed to paint her insides white. "My balls are feeling full tonight, sister! I'm going to fucking drown you!"
Danika was very much aware of how much cum her sister had inside her – said balls had been beating out a savage rhythm against her face for what felt like the last hour.
"Where do you want it?" Lariel snarled, ripping her cock from the demon's throat.
"Wherever you want me to take it!" Danika gasped obediently, still furiously rubbing her slit.
The angel leant down and spat on the demon's face, then rubbed her hand across her crimson features to smear her saliva over her cheeks, her nose, her lips, in a slimy sheen, feeling Danika's lips drag against her fingers in a subconscious attempt to suck on them. She slapped her sister again, and the demon's mouth hung open at once to take the angelic shaft back into its hot depths.
"Good girl," Lariel purred, reaching down to grab a fistful of glossy hair, feeding Danika her pale shaft until the demon's nose was smothered by her balls. A few more hard, deep thrusts, and the tingling in her cock was too much to hold back.
Lariel hunched over her sister's body, her hands leaving Danika's throat to join the demon's own, squeezing her crimson breasts hard enough to leave marks, and cried out as her cock began to spew the contents of her swollen balls straight into the demon's waiting stomach. Lariel groaned as she drained her balls into her willing cumdump, her cock throbbing painfully as it found release.
Danika let out a muffled groan as she felt the first blasts coat her throat, her face skewered on the angel's rod as it disgorged its heavy load. A boiling tide of cum rushed down her throat, gurgling into her stomach to fill her insides with a lake of thick, angelic seed. She reached around to grip her sister's round ass, pulling the angel in tightly as she choked down the tide of sperm, the muscles around in her neck tensing with the effort of swallowing it all.
The demon gagged lovingly on her sister's cock, one hand pulling away from her sister's springy asscheek to trace her fingers over her navel, feeling the smooth skin tensing as she was fed a liquid meal. Her eyes rolled back in her head and she convulsed on the altar, her body shuddering in delight as what felt like a pint of angelic cum was pumped down her throat and straight into her belly. She felt it churning inside her, a sticky, boiling lake of her sister's cream, and sparks flew across her vision as her oxygen-starved lungs burned. She was flying, lifted aloft, her insides scorched by the torrent of spunk flooding her guts.
Danika could feel herself being filled to the brim, her stomach gurgling in protest as it reached its limit – her sister's promise to drown her had not been one made lightly. She choked, a trickle of cum bursting from her lips, and a spasm rocked her body. She forced herself to swallow down her gorge, not daring to waste the gift that her sister had just injected into her now-tense stomach, and Lariel growled appreciatively as her sister's throat contracted around her pulsing shaft.
The angel pulled out and aimed at the demon's face, stroking the last few spurts out to coat her crimson features. Danika gasped in a ragged breath, her gullet suddenly empty of the meaty shaft that had been blocking it, only to choke as her sister shot straight into her open mouth. She gagged again, the last splashes of Lariel's cum painting her cheeks, her eyebrows, and forehead white as gravity dragged trickles along her upside-down face and and sent them rolling slowly along her horns, and she fought for breath as thick cum clogged her nostrils.
From her hair to her chin, her lips to the depths of her belly, the demon was coated in cream, her crimson flesh lacquered with hot icing. Pearly blobs clung to her hair and hung between her horns, thick strings joined her lips as she panted heavily, and long trickles shot over her neck as more gurgled within her. Her chest heaved, her breasts moving softly as she drew in deep breaths.
The angel lunged down to her, tangling her fingers in her sister's hair, pulling her in for a sloppy kiss. She groaned as she tasted herself, their tongues flickering against one another. Danika pulled away and rolled over, propping herself up on one elbow to let her sister see her cum-painted face. She grabbed her sister's still-hard cock, squeezing it hard enough to make the angel gasp.
"Still got a bit more in you?" she teased, strings of cum bridging her lips as she spoke. "I want you to just stretch out more than just my throat."
"Such a whore," the demon replied, her voice a pleasured growl. "Bend over. I want your ass."
Danika giggled, swinging her legs around and off the altar, and obligingly bending at the hips, her legs straight and spread. Her sister pushed down on the small of her back, trapping her against the marble. The cold edge of the altar dug into her thighs, her flesh bulging around the unyielding stone. She shivered as thrill of anticipation ran through her. She knew that she would walk out of the church on shaky legs, her asshole sore and satisfied, leaking divine seed from her holes.
Her sister's finger trailed seductively along her slit, up to her pucker to moisten it with her own juices, then curved off to stroke over one rounded asscheek.
She remembered the first time she had felt her sister's finger probing at her virgin rosebud, the slender digit circling and pressing, coaxing her to relax, the demon's trepidation bordering on fear, afraid and yet desiring. The angel had calmed her, whispering breathily into her ear, pulling her close as all the while her finger massaged the demon's untouched rim, gently asking it to open, to let her in, to loosen just enough to forget why she had ever worried about being tense.
And then she had forgotten, for just long enough, why she was nervous, and her eyes had shot open and a gasp slipped from her lips as suddenly her sister's finger was inside her, wiggling, the second knuckle clenched tightly by her muscular rim. She had moaned as this new sensation overtook her, and by the time her screams had finished ringing in the air two hours later her ass was no longer virgin, but knew what it felt like to have three determined fingers pressing against its walls.
Now she stood bent over, thighs tense, her asshole winking in anticipation, loosened countless times now by her sister's cock and fingers, the memory of its first plundering a ghost among many.
The angel let herself gaze at her sister's mirrored body – her perky ass, her firm thighs, the delicious curve as her hips tapered into a slim waist. The sight sent shivers through her that stiffened her rosy nipples, and her cock hardened in her hand. Still pushing down on her sister's back she wiped her hand over Danika's face, working her fingers into her mouth, lubricating her skin with spit and seed. A smirk curving her lips, Lariel reached between her sister's cheeks and slipped two fingers into her pucker without warning, pushing up to the last knuckle.
The demon's head shot up, glistening strings connecting her face to the smooth surface of the altar, and she moaned at the sudden, rigid invasion.
"Oh, you whore!" Lariel drawled as her sister's thighs trembled, her hips making tiny gyrations as she tried to take in more. "Squirming like some college slut having her asshole played with for the first time." She shoved in another finger, scraping at the sensitive walls of her sister's anal canal.
"Please..."
"Please what?"
"Please put another in, sister!"
"I'm not your sister right now," she snapped, flexing her fingers outwards to cause pain to surge through Danika's rim. "I'm your fucking mistress."
"Please, mistress!"
The angel rewarded her by slipping her last finger all the way in, tucking her thumb in to make a point.
"That's a good bitch."
"Yes! I'm your bitch, mistress!"
Lariel's other hand had crept to her wet cock, slowly stroking it to the sight of her mewling sister and her asshole being stretched out around her slimy hand.
"Before you take my cock," Lariel said, gently pushing her hand in to the widest point, "first you can take my fist!"
With a vicious shove, her whole hand vanished into the demon's now-loosened hole, Danika's elastic rim closing like a winking eye around her wrist. Danika howled, a painful, delicious ache spreading up through her belly, washing over the nerves that lined her passage.
"Too much?" Lariel asked mockingly.
"N-no, mistress!" Danika gasped.
The angel forced herself to keep her fist where it was, slowly rotating her arm to elicit grateful moans from her sister. She wanted so desperately to plunge all the way in – once, she had gotten her arm in almost up to the elbow, and the demon had been unable even to gasp at the sensation, so fried was her brain. She smirked to herself as she remembered how Danika had looked down at her with a mixture of lust and lewd fascination, the bulge of her sister's clenched hand clearly visible through her trim stomach.
But this time, Lariel wanted some part of her sister's bowels untouched that would then light up when her pale rod plunged in, scorching nerves that this time had been left undefiled by her clenched fist.
This part was just foreplay to the angel, a shallow appetiser for the thorough stuffing that her sister was about to receive.
Lariel smacked a crimson asscheek, causing Danika's rim to tightly grasp her wrist. Then she pulled her fist out, ripping past her sister's rim with a whimper of pained pleasure from the demon. Danika's asshole slowly winked closed, her bowels reluctant to see their visitor leave.
"Nnngh..."
"Was that good?" Lariel snarled, slipping her fingers into Danika's mouth. The demon immediately sucked on them, tasting the bitterness of her own ass mixed with the spicy cum that had served as lube.
"Ungh..."
Lariel shoved the demon's shoulders down, pressing her cum-painted face against the cool surface of the altar.
"Look at you," she hissed, slapping the demon's crimson cheek with a wet smack, smearing cum and spit over her face. "You're a fucking mess. You want more, don't you, you greedy slut?"
"Yes!"
"Do you want me to fuck you?"
"Yes!"
"Do you fucking want it?" the angel snarled, grabbing a fistful of the demon's hair and smearing her slimy face against the altar.
"Yes! I want it!"
"Louder!"
"Please, mistress, I fucking want it!" the demon shrieked, desperate to be speared on the angel's thick shaft, the memory of the angelic fist still aching inside her, the tantalising prelude of a deeper, harder fucking to come. "I want you to fuck my ass!"
Lariel was fully in the grip of her lust now, riding a wave of savage joy, her cock throbbing as she watched its pale length rise over her sister's dark asscheeks. She wanted to shove herself fully into the depths of her bowels, her base throttled by Danika's tight rim, her only desire to make as much of a creamy mess inside her sister's guts as she already had on her crimson face.
Then she remembered that she already had, and giggled to herself as she lined up her cock in the crimson cleavage of her sister's ass. She poked gently against Danika's rosebud, daring her to open up, drawing out tiny gasps from her sister. Her spongy dome pressed against the muscular circle, and at the determined pressure Danika pushed and relaxed her loosened sphincter to let its new visitor in.
Lariel's head popped in, her sister's rim still tight enough to pinch her shaft, and she pushed her cock in after it, sliding in almost all the way, further and deeper than her fist. They moaned together as sensitive walls massaged Lariel's thick fuckrod, and the demon's bowels relaxed to form a sleeve around it.
The angel's clenched fist had been a battering ram against her muscular rim, a blunt object that forced her open. It had opened the door, but now the angel's cock would plough through that door, riding the dull ache left behind, and keep on going deep into the demon's guts until she felt not just stretched, but full.
Just as with the deep facefucking that she had inflicted on the demon, Lariel started with a slow, steady pace, sinking most of her cock in before pulling out, never quite fully sheathing her length. Her cockhead scraped along the walls of Danika's ass, eliciting small moans and whimpers of pleasure from the bent-over demon. She scratched her nails down the demon's back, delighting in the shivers that passed through her crimson body.
"How does that feel, bitch?" she purred, trailing her hands over Danika's hips and ample ass.
"So good!" the demon moaned, juddering against the altar as she was rapidly reminded of her love for her sister's cock. "So good, mistress!"
"You can take it harder, can't you?"
Without even waiting for a reply, Lariel grabbed Danika by the waist and slammed fully inside her, pushing up hard against her perky ass as she filled the demon's bowels as far as she could. A raw groan slipped from Danika's mouth, her hands clawing uselessly against the stone as ripples of pleasure spread through her, a throbbing that drowned her in warmth and bliss. Lariel held herself there for a moment, enjoying the sensation of her sister's passage squeezing her whole length.
Then the angel began to properly fuck her sister, coring out her asshole with her pale pole, churning the cum coating her guts like butter, spearing her with no intention of going easy on the demon's tight sphincter. The air was immediately filled with a barrage of curses and pleas, the demon alternately screaming out her pleasure and begging her sister not to stop. Lariel spanked Danika's jiggling cheeks, which would have been blushing red if they weren't already an infernal crimson.
Lariel grabbed an handful of her sister's dark hair, holding her head down against the altar, forcing her to submit to the raw pounding in her asshole. Danika's breasts squished out to the sides, bulging like ripe fruit as the angel shoved her down, dominating her with long, deep strokes of her cock.
"You like that, whore? You like the way my cock feels deep inside you?"
"Yes, mistress..." the demon moaned brokenly against the cool marble, strands of congealing cum and spit connecting her skin to the stone. Her mind was a cock-stuffed cave, her mind melted from the sensation of her sister's shaft piercing her, stretching her out, pressing deep into her bowels to fill her with its heat and girth. The nerve endings that her sister had left untouched by her fist now lit up in a blaze, overloading her brain in a barrage of raw pleasure.
Danika pushed back, trying to throw her hips back against Lariel's onslaught, desperate to meet her sister's thrusts with her own. She wanted the relentless hammering never to stop, for the ache deep inside her never to wane. When she crawled away from the altar after being used as a fucksleeve, leaking cum from her holes, she would tattoo her sister's name in white ink around her rosebud, so that she would never forget which angel owned her.
"Oh, fuck yes!" Lariel cried out, her cock seeming to get even harder at the sight of her sister submitting to her heavenly shaft, letting herself be used as as piece of fuckmeat for the angel's whims. Lariel dug her fingers into her sister's hips, gripping her tightly as she slammed into Danika's slippery asshole, her thighs slapping noisily against the demon's ass. Danika's nails scratched feebly on the smooth altar as she tried to find purchase to push herself back, and the sight gave her sister an idea.
Lariel grabbed ahold of Danika's wrists and pulled back on her arms, and the demon's face was lifted from the surface of the altar, still connected to it by long, sticky strings. Her body shuddered and jerked like a ragdoll in time with the angel's brutal pace, her perky breasts thrust forwards as her back was arched like a ship's figurehead. Dark hair whipped around her head, sticking to the slimy sheen that coated her face, and her cum-stained lips parted in a long, animalistic moan.
"Take it! Take it all the way, you fucking slut!" the angel howled, her words echoing around the nave. She was completely in the grip of her lust now, frenziedly pounding her sister's asshole as though she were trying to completely break the demon's mind. Her cock was a tool to reshape her sister's bowels to its image, to turn her sister from a lascivious demon into a mewling whore, to make her crave only Lariel's pale cock plunging deep inside any hole that the angel chose.
The cold air resounded with the sounds of animalistic fucking – the wet squishing of Lariel's cock in its snug sheath, the hard impact of thighs against buttocks, the moaning and panting of the two sisters as they let themselves get lost in mind-bending anal sex.
The demon was sweating, groaning, her ass cushioning the thudding impacts of her sister slamming her, the angelic cock stirring up a warmth inside her that had only one outcome. She felt herself start to fall into a soft emptiness, the mind-emptying prelude to a shuddering orgasm.
"M-mistress, I'm...I'm...oh!" she could barely speak, lost in the grip of her rising climax.
Lariel knew all of her sister's tells – they had been fucking each other for years, and it hadn't taken long for her to learn when the crimson-skinned demon was drawing close. The fire that she was sparking in her sister's bowels caused Danika to clench her ass without even thinking, and she became limp, hanging by her arms in Lariel's iron grip. The demon's eyes fluttered, her face darkly flushed, and with one final thrust of the angel's pale cock she was engulfed in the flames of her climax.
"Cum for me, slut!"
"Oh fuck! Oh fuck! I'm cumming!"
Danika began to quake even as Lariel pulled even harder on her arms, her body spasming from the heat that exploded between her legs and flooded her with its warmth, her asshole utterly impaled on the angel's steely shaft. Danika's mouth hung open, a glistening, lewd O dripping with strings of drool, and she cried her thanks into the cool air with a raw, throat-ripping cry. Her tight rim clenched and relaxed, squeezing her sister's cock as it rammed in and out like a runaway piston.
Lariel felt it, the unmistakeable tingling that started in her mushroom-shaped dome, spreading slowly down her shaft, the signal of her own impending climax. She leant forwards, taking one hand from her sister's arms to wrench her head back by the hair, not slowing down her ferocious pace in the slightest.
"I'm going to cum too, slut," she hissed into Danika's ear, her words punctuated by the slapping of flesh on flesh. "Are you ready for another big fucking load?"
"Uh! Y-yes, mistress! Oh fuck!" Danika moaned, her words shaky as she struggled to form them amidst the pleasure that was awash in her brain.
"Good girl..."
She smacked Danika's taut ass, causing her sister's sphincter to pinch her tighter than ever, and she groaned as she felt the floodgates open and her balls begin to twitch as they unleashed their steaming payload.
Danika felt it boiling through her bowels, a scalding tide of cum that burst into her guts to join the lake that already sloshed about there. The demon moaned dazedly, her belly growing tighter as it was filled to bursting, pressing against the cool marble beneath. She could feel it swirling deep inside her, swelling her trim stomach like a balloon, a sharp pain lancing through her that she took with delight.
Then, as had happened so many times before, her guts could take no more, and her throat began to contract as her body desperately tried to find a way out for the deluge of cum that filled her like a waterskin.
She heaved, as first a trickle, then a wave of hot cum spilled over her lips and she retched, head hanging forwards, splattering the marble altar with an offering of fresh seed. She gagged again, spurting like a broken fountain as her insides purged themselves of their overflowing bounty, pearly cream running down her chin to drip from her stiff nipples, splashing against the altar. Her dark lips were parted and glistening while she puked sticky seed down her own body, her features utterly lost in her new position of cum-dripping, fuck-drunk slut. Droplets flew from her body as she shook from the pounding that her sister not once slowed.
Stars spun across the demon's vision as her throat was clogged with cum, her ability to breathe cut off by the one-way torrent that heaved its way up through her body. She choked, spraying cum while she made wet sucking sounds in her attempt to pull air into her burning lungs.
Lariel only fucked her harder at the sound of Danika gagging, her cock throbbing with the liberating ache of release as she disgorged her load into the overflowing demon's asshole. She knew that her sister loved the fight to stay awake, the lack of oxygen magnifying the afterglow of her orgasm until it was as though a miniature sun was born inside her.
"Yes! Oh my god, that's so fucking hot!" the angel screamed, ramming her cock into her sister's bowels even as cum spurted from the seal of her tight rim to splash against Lariel's thighs. "Choke on my cum, slut!"
The altar in front of Danika was awash with fresh, frothy seed, slathering the cold stone in warm wetness. Lariel cried out once more, savagely pushing into the demon's asshole as far as she could, her balls utterly drained, and let go of her sister's arms. Danika collapsed forwards into the sticky puddle of cum that she had puked up only moments before, her arms shaking too much to hold herself up. She pulled her legs shakily up from the ground, her thighs marked by indentations from being pressed against the edge of the altar. The demon panted for breath, eyes fluttering, lashes stuck together with cooling jizz, her face frosted with cream.
Lariel moaned and sank down next to her, her arms now wrapping protectively around her sister's exhausted body, her dominant role evaporating into the air now that her lust had been slaked. She drew Danika into her, their bellies sticking together from the gooey mess between them, and stroked the demon's cum-striped hair and horns, pressing her pale forehead against her sister's to anoint herself with her own seed.
"That was good..." she murmured after a while, and Danika gave her a small, exhausted smile. "I fucking love it when that happens."
"Same here," Danika replied, flickering her tongue over her sister's lips, letting her taste herself. "I love when you make me your slut."
"Mmm..." Lariel purred. "And just think, you were once so nervous about letting me into your ass."
"Fuck...I'm so glad that I did in the end."
They lay there for a while, the pool of angelic cum slowly congealing around them.
"You made such a mess..."
"You made it, I think you'll find," the demon said impishly. "My place, next time?"
The angel looked at her sister's face, piercing amethyst eyes shining through the cum that glazed her crimson skin.
"Sure," she said, absently dragging her thigh between her sister's legs. "House of hell, next time."
