Author's Note

Lewd warning, there will be incest and Sonata has a surprise.

Not for the faint of heart, or the delicate of mind.

Third Time’s the Charm! (Lewd)

“So you broke into the house of an Incelibate...” Adagio lectured. “Dressed as the Grim Reaper, in some elaborate plan that Sonata cooked up, to gain demonic powers for no other reason than to have them.”

“Uh... Yeah.” Aria answered, a bit unsure on how to react. “I mean, why else would I be there?”

“We even stole his soul!” Sonata cheered, but was quickly silenced by Adagio’s ‘shut your goddamn mouth’ look. “Erm... We got a pretty crystal for it?”

Adagio poked her nose and said in a venomous tone. “Not. Another. Word.” Her command went unbroken as Sonata curled up in shame, looking down at her knees like a scolded toddler. “Your so-called ‘Crystal’ is a meta-physical atrocity to humanity, nature, and God himself! It’s an actual, living soul! It’s an artifact that could stir war and violence among Religious ethnicities!”

“It could also tell Athiests to shut the fuck up for once in their-“ Adagio looked at Aria with bloody murder, ‘not another fucking word’ her eyes screamed. “Pathetic... Pessimistic lives.”

.......

“Yeah, Athiests Are doo-doo heads!” Sonata added, causing Adagio’s eye to twitch. “Especially the kind that thoughtlessly push their ideals and beliefs onto people who just like living their lives the way they want.”

“That’s called an asshole, Sonata.” Aria corrected. “And what do we do to assholes?”

Sonata purses her lips in thought... “Oh, oh! We fuck ‘em raw and laugh as they cry in their own blood and shit!”

Aria smirked. “Just like I taught you, sis.”

Adagio, well aware she was being blatantly ignored, just huffed with a half-lidded look of disappointment.

“But, uh... I got a question, Aria.” Sonata began. “Like, when I go and fuck an asshole, there’s a lot more blood than I think is necessary.”

...........

“They also... Die.” She added, rubbing her arm with a blush. “Like, aside from one guy, every ass just splits open and it’s just... It’s really messy.”

“Sonata, are you saying you have a massive demon cock?” The demon didn’t answer, she only looked downward in shame. “You gotta tell me what that murder-cock looks like, Sonata.”

Adagio face-palmed. “Lord give me strength...” Adagio, feeling her patience being pushed well beyond what she deemed tolerable, somehow held back the urge to slap the two of them into a coma. “Can we please stop talking about death by forced sodomy? It’s both disgusting and unnecessary conversation.”

“I-it’s...” Sonata held the rim of her skirt. “Barbed... A-and really scary to look at.”

“That doesn’t tell me very much, Sonata.”

“Would you two-“

“No, Aria stop!” Aria was trying to pull off her skirt, her own sister’s skirt in front of God and everybody. “D-Dagi, get her off!”

Adagio just... She gave up, having bear witness to this inhuman scene, watching her broken family spiraling out of control like a semi on a frozen highway and falling into what will likely be incest by most definitions...

“Adagio’s not here, Sonata. Don’t bother leaveing a message.” She needed a drink, bad. “Now if you’ll excuse me, I have a date with a bottle of champagne.” She walked out, likely to her room so she could drown herself in alcohol.

“...Kay.” Aria resumed fighting her sister to uncover the legendary murder dong. “Just show me the dick!”

“Nooo!” Sonata was definitely stronger than her mortal self, though not really by much. Aria, unsurprisingly, was around that level as well. “Don’t...! You’re my sister!” She pleaded. “And this is my favorite skirt!”

The tug-of-molestation continued. “Come... On, Sonata! Demon cock doesn’t just... mph! Fall from trees!” Sonata won the fight with one last tug, with Aria loosing her grip and falling back on the floor. “Ow, dammit.” She rubbed her head in pain, Sonata beating her wings and clinging onto the ceiling like a spider. “Oh come the fuck on, Sonata! You’re a demon, aren’t you!? You should be happy to indulge me!”

“Demons aren’t all the same, so don’t demon-shame me you labeling pig!” Way to defend your demon blood, Sonata! Aria has no say in how you act, especially in a case involving the gender-roles and stereotypes of an infernal soul! “S-So... Nyeh!” She stuck her tongue out at her older sister for good measure.

“Ugh... Fine!” Aria relented, resorting to proper negotiation. “Whataya want from me?”

“I want you to not touch my... M-my thing!” She stuttered with pink cheeks. “Why do you wanna see it anyway!?”

“Who doesn’t wanna see what a demon’s dick looks like!?” Solid argument, if I may speak for all of us still riding this train-wreck of a story. “That’s like... Um...” She pondered a bit. “Nobody likes watching a car crash, right?”

“...Yeah?” Even Sonata was visibly confused.

“But like, everybody sorta wants to see one, you follow?” Her face said ‘kinda, but not really’. “Okay, why did you wanna become a demon?”

“...Because I thought it... Would be kinda...”

...............

”Ohhhh... I think I get where you’re coming from!” Yeah, Sonata’s really not that hard to manipulate. “You wanna know what it’s like to have unrivaled power over lesser mortals!” Close enough, Sonata. “Well if that’s the case, get one yourself!”

“...Okay, not a bad idea if I knew what it looked like first.” She was given a raspberry as a proper ‘fuck you’. “Come on you big baby! I’ll do anything!”

She was answered with silence...

Aria, the ever-so-perceptive, was quick to detect lewdness. “Tell me you aren’t thinking-“

“I’m not!” She snapped.

“Oh my god, you are thinking it!” Aria started mocking her in a sing-song tone. “Sonny’s gotta cruuush~!”

“No I don’t!” She argued back. “You’re mean and bossy and you steal from my mini-fridge!”

Aria debated in her head a bit. She could go two ways here; a). tease her for the rest of the day and maybe a bit more tomorrow, or b). as The Godfather once said ‘make her an offer she can’t refuse’.

.....

Well, Aria’s sense of morals have been irreparably warped ever since she watched Sonata vore that NEET a day or two ago. Plus she assumed she was going to hell either way for impersonating Death and being involved with the NEET incident. “Hey, Sonata.” Aria began in an innocent tone. “I was wondering, what you were thinking about just now?”

“...Nothing.” She answered.

“Hmm...” Aria sat down on the couch. “I’ll do it if you ask nicely.” She offered.

“Do... What?” Sonata asked.

“I already told you...” Aria smiled, she had her on the hook. “Anything.” She answered with a honey-coated voice.

Sonata shifted her thighs uncomfortably, clearly trying to be subtle and failing miserably. “This is a prank.” She claimed. “You’re... You’re lying.”

“Try me.” Aria dared, reeling in her metaphorical catch. “You know you want to, sis...”

.....

.....

.....

Sonata let go, fluttering to the ground with her back turned. “P-... Prove it.” She demanded in a shy tone. “Take your top off.”

Aria smiled... Her sister was as good as caught. She pulled off her shirt, leaving a sexy black bra for Sonata to stare at. “Look at me.”

When she did turn her head to see what Aria was packing, she let out a surprised yelp and quickly turned her head away. ”Holy cow...”

“You like?” Her breasts were absolutely gorgeous in that black bra, complimented her skin-color quite nicely and revealed just enough skin to tease the eye. Sonata definitely had a hard time resisting the urge to look. “Wanna touch ‘em?”

.....

”Yes.”

“Speak up, Sonata.” Aria asked. “Ask me properly.”

She bit her lip, but through sheer willpower she forced herself to say it. “M-... May I touch...”

“Touch what, Sonata?” Aria asked.

“Your... Boobs.”

Aria licked her lips. “Ask me again... Properly this time.” She didn’t even care they were related anymore. This kind of power was just... Addicting.

“I-I wanna touch your boobies... Please.”

“I might let you...” Aria slunk closer, holding her hips and whispering in her ear. “Can I touch yours?” Sonata nodded with a desperate whimper, Aria moves her hands up her sister’s waist and gave her tits a nice squeeze. “So big~.”

Sonata held in her breath to keep her moans down, until she felt Aria’s right hand moving down her belly. “A... Ariaaa~!” She didn’t listen, instead rubbing the tent Sonata was pitching under her skirt. “Please... D-don’t.”

“Tell me what you were thinking about, Sonny.” Aria whispered, fondling her fat tit and softly stroking her covered cock.

She resisted, it was clear on her face that she didn’t wanna say. But the groping and rubbing was just beating down her wall of resistance like a battering ram. “Ngh~! N-no, I... I wasn’t...”

“You wanted to fuck me, didn’t you, Sonata?” Aria could feel her cock twitch for an instance, bouncing up against her hand. “Is that what you wanted?” She only whimpered pathetically, biting her lip to force her voice down. “You know, Sonny...” Aria started popping off the buttons of her sister’s top. “I wouldn’t mind doing that stuff with you.” Aria kissed her neck, soft and slow. “All you gotta do... Is tell me.”

“St-op!” She begged in a quiet shout. “Please... I’m... I’m gonna...!”

“Gonna...?” Aria felt an intense pulsing from her finger tips. Sonata squealed loudly as her dick started throbbing and... Making her skirt into a new cum rag. “Sensitive, are we?” She gave it some gentle pets before going back to squeezing both of Sonata’s breasts, exciting a loud moan from the lucky girl. “Did that feel good?” She was clearly drunk with euphoria, with a glazed stare toward the ceiling and sweat-silken skin. “Ready to tell your big sis the truth now?”

Battered and worn, Sonata had fought a stubborn battle. But after cumming in her own clothes, at the hands of her own sister, along with all the groping and the hot breathing on her neck... “I was... Thinking of you.” She finally admitted. “D-doing stuff.”

“Keep going.” Aria got the last button on her top, pulling it down and unhooking her bra.

“Y-you... Mmph~!” Sonata gasped at the snap of the hook, and moaned when her stiff red nipples were pinched. “You were playing with yourself... With your boobs and your... Ngh~!”

“You wanted to watch me finger myself?” It was almost laughable how innocent Sonata was. “Is that all you wanted?” Aria let her go, unbuttoning her pants and dropping them to her feet. “Pull out your cock and I’m aaall yours, sis.”

Dirty, incestuous thoughts were filling her brain. Images of forbidden skin, and the silky, warm folds of... Ooh, she was getting hard again thinking about it. “Do I get to see it?” She asked.

“Turn around and find out, Sonny.” She took a moment to prepare herself, then finally turned. Aria was naked on the couch, purple plump tits and wet pussy uncovered. She beckoned her over with a finger, Sonata blindly obeyed as she shamelessly stared at her sister’s sexy body. “Get in real close, Sonny.” Aria licked her fingers and started rubbing herself first. “Mm, it’s so hot.” She dipped her middle in first, licking her lips as the much-needed sensation. “Touch me, Sonny.” Just as promised, she got to manhandle Aria’s tits. “Mmmm... More~.” The pointer went in this time, she felt so hot being fondled like this. “I’m so horny, Sonny~!” She moaned, catching her sister’s attention. “Gimme that fat demon cock, I gotta see it!”

She wined a bit like a hurt puppy, but kept her promise and stood up. “It’s... H-here.” She raised her skirt up, and what looked like a whole foot of throbbing, thick demon dick stood proudly for her. The shaft wasn’t quite ‘barbed’ but definitely had a lot of small quills lining the skin, along with some bumps lining both sides. The head was odd though, rather than the human flat-variety the tip was pointed with two smaller horn-like bits at the top. Looked like a little triceratops head with the urethra at the center of the three points. “It’s weird, isn’t it.”

“It’s huge!” Aria gawked. “Star Swirl be damned... That’s gonna stretch me so much.” Looking at it, imagining what it was gonna do to her... She wanted it, bad. “Sit next... N-next to me!” She did as told, Aria grabbing her girth and jerking her off.

“W-wait, aahh!” She moaned out at the sensation, softly rolling her hips as she held the couch in a death grip. “Fuck...! N-not so fast!” Aria noticed that, below the throbbing demon dick, Sonata still had her vagina. Seeing an opportunity, she took her fingers out of her own lips and shoved them into Sonata’s instead. ”Noh! N-Nuhh!” She was being pleasures in two places, and it was melting her brain. “Stop! N-no! Not... Not There!”

“When I get my demon cock, Sonny.” Aria panted out. “Your pussy is mine.”

The images of Aria fucking her raw with her own demon cock sent a warmth down her spine, her womb was tingling with wanton breed lust. “I want it, Aria! I want your cock~!” Aria wrapped her lips over the tip and went right to work. “Ohh! Oh Lucifer!” She could feel Aria’s tongue tickling her tip. “Mmmph! Ahh!! Oh Aria, please don’t stop!” She couldn’t stop thinking of her pussy, couldn’t stop thinking of how warm and wet it felt inside. “I-... I want you, Aria!” She moaned out with longing in her tone. “You’re so fucking hot, Aria! I love everything about you!” She mindlessly babbled, Aria spitting her dick out and squeezing it between her tits. “Oh fuck...! A-Aria I’m gonna cum!”

“Yeah, gimme that cum!” She opened her mouth wide, teasing Sonata’s tip with her tongue. It throbbed and twitched in her chest until Sonata groaned, and a jet of cum hit the roof of Aria’s mouth. She locked her lips over the head and caught every last rope. It was spicy, as cliche as that sounds, so she ended up spitting it out from the burning in her tongue. “Ugh, fuck...” Sonata was still hard from the looks of it, not even the least bit tired, either. “Still not soft, huh?” Sonata’s eyes were distant and foggy, but the normal blood-red was a hot pink now. “Ready for the main course, sis?” Aria asked, spreading open her lips for her demon lover.

Sonata crawled to her like a sexy kitty cat, tail swishing left and right, and... A tail? ”Sex~!” Aria was pushed down by her drooling sister, who locked her in a fiery-hot kiss, tongue and all.

’SLAM!!’

Both parties jumped, and stared at the hallway as their eldest sister trudged out with-”YOU’RE FUCKING LOUD!!”

’Smash!’

.....

Well... She had a bottle of liquor, but now it was a mess of glass and tonic all over the living room wall. “I’ve had it-“ She pointed at the ceiling. “up to here with you two! You-’hic!’ You four... Six?” She was very, very drunk. “Stop fuckin’ spinning already!” She inhaled, and exhaled a wail of sorrow as she broke into tears. “I try so haaard! Auuugh!!” The two incestuous lovers just stared at her pathetic crying for maybe half a minute, before angry Dagi came back and screamed at them. “You disgusting West Virginhegh Hicks! You fucking pieces of trash!” She puked in the floor and cried, then got angry at nothing again. “Have your goddamn incest baby! See if I care if one horn’s on it’s motherfucking arm and the other has to be-’hic!’ surgically removed! SEE IF I CARE ABOUT YOUR HEALTH AND RETARDED DEMON CHILD!!!” She got up and ran for the kitchen, smashing her face into the wall and vomiting on herself. “Fucking... FUCK THE BOTH OF YOU!!” There was a loud thump, and just like that Adagio was... Hopefully not dead.

.....

“What the fuck is her problem?” Aria’s question would go unanswered, as thick demon cock would smash her brain into mush like a pumpkin full of fire crackers. “Ugh... Haa...” She was already cumming, with violent shakes, a throbbing asshole, and demon tongue sucking her tit. “Ah-... Auugh! Fuck!” It felt like hours, many many hours of fat cock in her guts, yet only ten minutes had passed until Sonata bit down on Aria’s neck and unloaded deep in her sister’s pussy. “Ohh... Oh god, it’s so-Ahh!!” Sonata immediately went back it humping, Aria screaming as another orgasm rocked her world.

Little did she know, this would continue for six straight hours.

Adagio had awoken with one of the most head-splitting migraines she’d felt in years. Her memory was a blur at best, lots of screaming and crying. “Oh...’Urp!’ Oh god in heaven.” She was laying in the kitchen floor from what she could see, reeled of puke and booze. “I’m such a train wreck.” She took her time standing up, not wanting to upset her poor stomach any further. Once she was on her wobbly feet she went to the living room to...

.....

She witnessed a sight so heartwarming, Aria and Sonata sleeping together on the couch.

What wasn’t so heartwarming was all the blood staining the couch, and what looked like human organs between Aria’s thighs.

.....

.....

.....

Adagio just stood there, eyes fading into grey as she felt the last bit of reasoning leave her heart. She was empty, so so empty inside. She knew she could’ve stopped this, she could’ve saved her sister, but instead she drowned out her depression and stress with alcohol.

Aria was dead, Sonata was a demon, and the world just keeps getting grayer and grayer and grayer...

’Crackle... Snap!’

Adagio was broken of her downward spiral by the odd sounds of Aria’s corpse. She was twitching and popping, a sight so grotesque and abnormal it was just the thing to distract Adagio from the thoughts of suicide. “A-... A-Aria?”

’Crack...!’

.........

Aria’s corpse stopped twitching...

’BOOM!’

And it exploded in an absolute swarm of maggots and spiders, blood showering the room and Adagio as her sanity slipped even further down the rabbit hole... But what lay in Aria’s place, where only a twitching leg and bits of her hair remained, was a small black child with tiny antlers and a thick reptilian tail.

Adagio laid down on the floor, curled up into a ball, and silently cried while blood oozed down her face and insects crawled over her broken form. The only form of support she had was the crying of a baby that put her feminine heart in a very small warmth of ease, a thin blanket to weather a blizzard of insanity.
