Adagio flipped through the pages of her book idly, relishing in the rare moment of silence she was currently enjoying. Living with her sisters was always a pain in the ass, and the situation was made no better by their crushing defeat at the hands of the Rainbooms. Not only the fact that their only ambitions had been thwarted, and not only the fact that their ruined pendants left the Sirens hungry and irate, but, for reasons Adagio still had no good explanation for, the Rainboom’s magic had strange physical effects.
Not on her, or on Aria. For some reason, they were entirely unchanged. It was only Sonata who had been changed by the strange Equestrian magic, and the transformation wasn’t even visible to the average on-looker. It was a change that, while it was targeted at Sonata, negatively impacted the entire Dazzling household.
“Adagioooooooo!”
Adagio sighed, bringing her book closer to her face in a futile attempt to hide from her sister. A very small, naive part of Adagio thought that if she was quiet, Sonata would go elsewhere. Of course, she couldn’t be that lucky. Sonata entered the room, looking much like she did after any day of school; Tired, whiny, and undoubtedly about to annoy her sisters.
She also had ripped her pants off the moment she stepped into the threshold of the house to free her big, thick, heavy, magical cock.
“I’m going to regret asking,” sighed Adagio, still not daring to look at Sonata. “But what do you want?”
“Today was, like, really hard at school,” complained Sonata. “There was a pop quiz that I wasn’t ready for, and I forgot my homework, and there were so many cuties wrestling around in Gym, and—”
“What. Do. You. Want.” The problem was, Adagio already knew exactly what Sonata wanted. The more that Sonata danced around the point, the more Adagio had to deal with this frankly ridiculous situation. The sooner Sonata got to the point, the sooner Adagio could tell her to take a long walk off of a short pier.
“I’m just… Like, really horny, and I was hoping…” Sonata grabbed her cock, easily a foot long and too thick for her to grab her hand around. “Could you maybe, pretty please with a cherry on top… Suck my dick?”
And there it was. Adagio knew that it wasn’t Sonata’s fault that this happened, and that she had no control over her strange futa hormones. That didn’t stop her from being massively annoyed by the fact that this kept coming up. Worst of all, Adagio knew she had no one to blame but herself. Within the first month of being “gifted” with her massive cock, Sonata had taken to begging Adagio for help in relieving herself. After a lot of whining from Sonata and a few glasses of red wine too many, Adagio caved and gave her sister a drunken, pity-fueled blowjob. This proved to be a mistake, as now it was borderline impossible to get Sonata to take no for an answer.
“Sonata, I’ve been working all week. This is my only day off for another month and a half. I do not want to suck your dick. I want to read my book,” said Adagio, hoping her slow, even, reasonable tone would get through to Sonata.
“But Dagi! I feel like I’m gonna burst!” whined Sonata, dashing Adagio’s dreams into shards. “Please? Please? Please?!”
“No! I’m not putting that thing anywhere near my mouth ever again! You need to get off so bad, go rub one out in your room.”
“Can’t. Internet is out, I don’t have any porn. Please, Dagi, it’s not like you’re busy or anything! Would you just—”
“I’m trying to read, you dunce! And I’m not going to stop what I’m doing just so I can get a mouthful of cum!”
It got quiet for a second as Sonata really thought about the situation. She wasn’t sure if she believed Adagio’s excuse. Nobody reads for fun! So Adagio must’ve really been against this idea, which means Sonata would have to try and sweeten the deal.
“I could cum on your face if you don’t want it in your mouth,” suggested Sonata.
Silence fell over the two again as Adagio studied her sister, trying to figure out just how it was possible for one person to be such a dumbass.
“Sonata, go away,” said Adagio flatly.
“But sis! What am I supposed to do with this!” demanded Sonata, pointing down to her dick. “It can’t suck itself! I don’t think…”
“Is there not anyone else willing to let you put your dick inside them?! Your idiot friends from school, one of those Rainboom cunts, Ari—” Adagio stopped herself, a simply foul, sinister idea brewing in her mind. “Why don’t you go fuck Aria?”
“I thought of that already, silly,” moped Sonata. She grumpily stomped across the kitchen, reaching into the fridge and pulling out a jug of chocolate milk. Much to Adagio’s disgust, Sonata popped open the top and took a swig straight from the bottle. “She’s never DTF, and she always gets really mad at me whenever I ask. She calls me mean names and throws stuff.”
“And she’s… awake when you try to fuck her?” Adagio asked what should’ve been an obvious question with a layer of confusion that made Sonata doubt her answer, even though it made perfect sense to her.
“Uh… Yes?” Sonata guzzled her chocolate milk, tossing the empty jug in the trash.
“Well, there’s your problem. Of course she didn’t want to fuck you, she was awake,” said Adagio, as if what she said should’ve been obvious. Sonata was confused, as was a typical response, which was good news for Adagio. “Don’t you know anything about your sister? She doesn’t like being fucked while she’s awake. She has some sort of sleeping beauty rape fetish or something. She really likes it when someone just goes up and pounds her silly while she sleeps.”
“Wha?! Really?” Sonata was amazed, and then immediately suspicious. This sounded like a trick, so she would have to be careful. “How come she never said that when I asked her to fuck before?”
“Because, dummy, it doesn’t count if she has to ask you to rape her in her sleep. Don’t be an idiot. No, you have to just go up and take her. She’ll love it.”
“Really?”
“Of course! She doesn’t talk about it because she’s ashamed, but I promise,” said Adagio with a devious grin. “The rougher you are, the more she likes it. Just remember, she’s going to scream for you to stop. She might even start crying. Don’t worry, that’s part of the fetish. What that really means is you should go harder!”
Sonata peered at her sister suspiciously for a bit, studying Adagio in search of some sign of deception. Adagio maintained her poker face, remaining calm and confident in the blatant lies she had just spewed. After a moment, Sonata gave a small nod, a wide grin spreading across her features.
“Okie doke, then! Gonna go fuck Ari then!” giggled Sonata, skipping her way to the stairs. “Don’t wait up!”
“You have fun! Oh, and don’t pull out, Aria loves a good creampie!”
Adagio smiled her disingenuine, artificial smile until she was absolutely sure that Sonata was gone, at which point her grin became notably more sincere and devious. She turned back to her book, chuckling to herself at her masterstroke of a plan. So simple, yet so effective. Adagio licked her thumb and turned the page of her book, laughing derisively.
“Fucking idiot…”
The sounds of Aria’s peaceful snoring filled her bedroom, completely undisturbed save for when Aria would occasionally toss and turn in her sleep. She was absolutely exhausted, and even her sisters (who very rarely gave her any due credit) decided she’d earned some sleep. Aria had been working hard, just as hard as Adagio, in order to cover her half of the rent. As such, she came home, stomped upstairs, and collapsed onto her bed. She’d give Adagio her rent money tomorrow. Right then, Aria just needed to relax.
She had slipped out of her clothes until she was comfortably in just her tanktop and purple boyshorts. After the day she had, Aria needed more than just a nap. She needed to blow off some serious steam. So, she locked her door, rolled down her panties, and slipped her fingers into her cunt to rub one out just before bed. When she finished off, Aria promptly faded into the clutches of sleep, not even bothering to pull her shorts back up to her waist. She had locked the door, and only she had a key. It wasn’t like anyone could get in and see her like this.
It wasn’t like Sonata had long ago stolen Aria’s key, made a copy, and returned the original before she even knew it was missing.
Sonata giggled to herself as she quietly slipped into her sister’s room, her cock twitching between her legs at the sight waiting there for her. While Adagio had an ass that drove Sonata insane, and Sonata herself had an enviable rack, Aria seemed to have been blessed with the legs in the family. Long, smooth, sexy legs, made all the sexier by the panties rolled halfway down their length and the dripping from her pussy that ran down her thighs.
Sonata crept forward, admiring her sister’s sleeping form for a bit. Aria looked so peaceful like this, her normally persistent scowl having long since faded into the gentle, contented expression she wore as she slept. Even though Aria was quite a heavy sleeper, Sonata made sure to be extra quiet as she tiptoed nearer and nearer Aria’s bed, eventually climbing onto the mattress and shimmying up to Aria’s prone, sleeping form.
Sonata’s hands found their way to Aria’s small, round ass, gently gripping and groping her while simultaneously pulling her closer. Aria, still deep in the clutches of sleep, let out an involuntary, unconscious moan, sending shivers up Sonata’s spine (and her cock). Not wanting to waste any more time, Sonata gripped her sister by the hip with one hand and her cock in the other, guiding her member to Aria’s hot, wet pussy.
Sonata bit her lip to stifle a moan as her tip penetrated Aria’s cunt, the tight hole inviting her in. Aria muttered something Sonata couldn’t quite make out, fidgeting slightly, but that didn’t stop Sonata by any means. Now that she had a taste of her sister’s tight folds, Sonata needed more, and more she would get; She gripped Aria’s narrow waist in both hands, pulling her back and forcing her onto her length.
“Fuck yeah,” breathed Sonata. She was so pent up, she felt like she would explode just penetrating Aria. She was so tight, so wonderfully tight, that Sonata couldn’t control herself. She was so glad that Aria secretly liked being fucked hard and without her consent, because that was exactly what was going to happen.
Sonata started slowly, gently thrusting into Aria. She didn’t quite go all the way, pausing her hips when she felt half of her cock in her sister’s pussy. Aria let out a yawn, which soon mingled into another involuntary moan. She fidgeted in her sleep again, inadvertently wiggling her hips and pushing more of Sonata’s length into her. Sonata shivered, the pleasure grabbing at her being and taking over. She held Aria by the hips firmly and buried the whole of her length in her sister, feeling the tip of her cock press against Aria’s cervix.
“Wha?” The pain and pleasure of Sonata’ cock suddenly penetrating her roused Aria from her sleep. She slowly blinked her eyes open, as if leaving a gripping dream. It took her a moment to process her surroundings, the hands on her hips, the cock spreading her lower lips. “What the fuck?”
“Oops. Didn’t mean to wake you just yet,” giggled Sonata. Aria tried to pull away, only for Sonata to use her deceptive, uncanny strength to hold her in place. “Oh well. Least I can go all out now!”
“Sonata, what the fuck! Let me go, you idiot!” Aria became more and more aware of her situation with time, the throbbing of Sonata’s cock sending waves of discomfort through her body. She jerked away, just for Sonata to grab a fistful of her hair and yank her back. “Ow! That fucking hurts!”
“You love it, huh?” Sonata slapped Aria firmly, groaning as her sister clenched up from the pain and made her already tight cunt even tighter. Sonata was impressed by Aria’s acting skills. It almost felt like she was seriously resisting. “It’s okay, sis, you can thank me later.”
“S-sonata, I swear to fucking God, if you don’t let me go, I’m gonna snap your fucking neck!” Aria bit her lip to stifle a moan as Sonata bucked her hips forward, burying even more of her cock into Aria’s pussy. “I mean it! If you don’t let me go, you’re dead!”
“You think you’re so tough and scary, but you can’t seem to do anything when you’ve got my big, fat dick in you.” Sonata wrapped her left arm around Aria’s throat, using her right hand to pull hard on Aria’s hair, yanking her head back and forcing their eyes to meet. “But I know you really like being treated like this. It makes sense! That’s why you keep bullying me, cause you wanted me to get sick of your crap and just fuck the bitchiness outta you!”
Aria growled in protest, just for Sonata to tug even harder on Aria’s pigtails, arcing Aria’s head about as far back as it would go. Sonata increased her speed again, smashing her hips against her sister’s savagely. It felt good, to be the bully for once. Even though Sonata knew it was all an act, it was so gratifying to get back at Aria for all the mean names and insults she’d endured over the years.
Of course, that didn’t feel quite as good as Aria’s tight, hot pussy, each thrust causing Aria’s entire body to tense and clench from the surprise, unwelcome penetration. Aria reached her hand up, wildly clawing for her sister’s face, but Sonata barely seemed to notice; instead, she placed her hand on the back of Aria’s head and shoved her face down into the sheets. Sonata pulled Aria’s ass up, using her foot to pin her head down, and gave Aria’s ass another firm slap before getting right back to work.
Sonata could hear Aria’s groans and moans through her mouthful of mattress, mingled with swears and threats, but she didn’t pay much attention. Even if Aria wasn’t pretending and actually wanted Sonata to stop—which, Sonata reminded herself, was not the case at all. She was just helping her big sister fulfill her fantasies—she was unlikely to care. Aria’s hot, tight hole, her moans of mixed pain and pleasure, the way her entire body trembled under Sonata’s grasp, it all felt too good to stop.
Aria bit her lip, trying to keep from breaking down. She was infuriated, humiliated that she was being thrown around like this, her embarrassment not at all helped by the way her body was reacting. Sonata’s cock was big, too big to take as quickly or roughly as she was now, but it was touching parts of her that had never been touched before. For every painful thrust, there was an accompanying arc of pleasure. Aria was disgusted, but there was no denying it; she was getting off on being raped by her own sister.
Sonata could hear Aria’s breathing pick up, her body jittering and convulsing with each deep, hard thrust, and she grinned. It looked like Adagio was right; Aria was loving it. Sonata could tell by the way that she gasped and twitched that Aria was about to cum, and she wasn’t too far from finishing in her own right. Sonata grabbed Aria’s ass in both hands, digging her fingers into her soft, supple flesh. Time to give her sister the finale she deserved.
“You really are liking this, aren’t you?” giggled Sonata, pressing Aria’s head down further with her foot to give herself more leverage to fuck Aria’s cunt even harder. “I can feel you tensing up, Ari! You’re gonna cum soon, huh? That’s right, cum on my cock, slut. You know you want to.”
Aria moaned into the sheets, shame filling her from the wave of heat passing over her. Sonata was right, of course. She was so close. Aria tried to fight it, to give one last act of defiance and somehow work her way free, but it was pointless. She was defenseless, entirely at the mercy of Sonata and her own biology.
Aria swore into her bedspread as her orgasm passed through her. Hot waves of electric pleasure beat down on her entire body, her legs quivering and her pussy tensing down onto Sonata, who couldn’t help but follow in her sister’s footsteps; Sonata let out a groan when Aria’s pussy seemed to clamp down on her cock, milking her for her cum. Her cock burst, firing thick, hot splurts of Sonata’s cum into Aria’s spread, used, sloppy cunt. Sonata moaned, packing her load into Aria with a few more deep, hard strokes. She pulled her cock free, letting the last few drops of her cum drip onto Aria’s ass and thighs.
“Whoa. I, like, really needed that,” panted Sonata, watching her cum drip out of her sister’s pussy. “Uh… Were you on the pill or something?” Aria slowly, shakily pushed herself to all fours, her heavy breathing, frazzled hair, and tangible fury giving her the appearance of a wild beast. “Probably shoulda asked before I creamed your pie, huh? Oh well, I think Dagi has some Plan B lying around somewhere…”
“Sonata… You’ve got until I can feel my legs again to get the hell out of here before I kill you with my bare hands,” huffed Aria, her face red and her eyes barely holding back tears. “If I were you, I’d start running.”
“Huh? Why are you mad at me?” Sonata scratched her head in confusion, only just then realizing that Aria was genuinely upset. “You did cum, right? I thought I was a pretty good fuck…”
“Alright. I can feel my legs now.” Aria stood up, cracking her knuckles. She grabbed Sonata by the throat, beaming pure, unadulterated fury into her sister. “You’re fucking dead.”
“Whoops.”
Adagio brought her mug to her lips, taking a slow sip of the hot, soothing tea as she read. Over half an hour had passed since she sent Sonata upstairs to fuck Aria, and judging by the fact she had yet to be interrupted, her plan seemed to have worked perfectly. She chuckled internally, reveling in her own genius. Now, she could enjoy her book in peace.
“I said I was sorry!”
Heavy, hurried footsteps on the stairs stole Adagio’s attention. Sonata was running downstairs, and, without saying a word to Adagio, ran through the house and out the front door. Adagio raised an eyebrow, and was about to return to her book when Aria ran into view. She had a noticeable limp and her legs were dripping with thick, sticky cum, but that didn’t impede her furious approach.
“You can run, bitch, you’ll just get to hell tired!” shouted Aria. She stopped in front of the kitchen, her eyes immediately landing on Adagio. Aria snarled, stomping her way over to her sister. “You!”
“Me,” said Adagio dryly. “Whatever this is about, could it wait? I’m nearly finished with this chapter…”
“Did you tell Sonata that I wanted her to rape me in my sleep?” demanded Aria. Adagio squinted her eyes, tilting her head in confusion.
“Why the hell would I tell her something that objectively stupid?”
“I don’t know, but she said that she thought it was my fetish and this sounds like some shit you’d do!”
“Think about what you’re accusing me of, Aria. Do you really think that I’d come up with such a nonsensical lie that any idiot with two brain cells to rub together should be able to tell isn’t true?” asked Adagio. “If I was going to lie to Sonata to fuck with you, don’t you think I’d come up with something that’s at least marginally believable? And why would I do this in the first place? So I can deal with your temper instead of enjoying my book?”
Aria glared at Adagio, studying her face to decide if she was lying or not. Adagio maintained the same calm, confident, almost bored facade that she had worn since the beginning, waiting for Aria to reach a conclusion. After a moment of thought, Aria let out a snarl, turning and stomping away.
“I’m gonna fucking kill her…” mumbled Aria.
“I’ve got a strapon in the shoebox under my bed, if you want to return the favor,” said Adagio, watching Aria left. Aria gave an affirmative grunt, mentioning something about washing up first. Adagio watched her go, waiting until she was completely out of view before picking up her tea and returning to her book.
“Fucking idiot…”
