“We only lost to those pathetic little Rainboom-bitches and Sunset Shitter because you're the worst of the worst!” Aria yelled at Sonata.
She hung her head and said nothing in reply.
The three defeated sirens were heading home and all in foul moods. Adagio was gritting her teeth.
She was sick of Aria always picking on poor little Sonata. Sure, she was a bit clumsy and not one of the brightest, but she still was their sister, she still was family!
Adagio clenched her fists. It took all of her self-restraint not to turn around to slap Aria and tell her to shut the fuck up. Sometimes Adagio felt more like their mother than their elder sister! She'd put up with this before, but tonight was even worse than usual. What finally crossed the line was when Aria unleashed a rant on poor Sonata.
"You're a total screw-up and a complete ditz! You have the attention span of a goldfish, we always have to waste our time explaining every fucking thing to you over and over again! Do you even realize how far up shit creek we are with our amulets broken? Did you even know what the amulets were for in the first place, or did you just wear it because it was shiny? And don't get me even started on your ridiculous obsession with tacos! If I had a taco right now, I'd shove it right up your ass, you degenerate little cunt!"
Adagio turned around and saw tears streaming down Sonata's face. She grabbed Aria by her dress, like she always did when she had to back up an order.
“That's ENOUGH, Aria! You lead the way back home now and then I will give you a piece of my mind!” she snarled at her.
Aria felt like being defiant and grinned at Adagio.
“And why in Tartarus should I listen to you anymore!?” she asked.
Adagio let go of her and pointed in the way to the sirens home.
“Because I say so! And now, move it because I'm losing my temper!”
Adagio may have lost her siren powers, but she certainly still had her intimidating attitude. Plus, her blood was boiling and she was about to explode like a hydrogen bomb. Aria finally did as she was told, muttering incomprehensible insults under her breath, and Adagio shot her a final death glare before turning to Sonata, who still was silently crying, and embraced her in a sisterly hug.
“Shhh... It's okay now. I will order you some tacos when we are back home, alright? Now stop crying, you'll only get a bad headache...”
Sonata hugged her back and by the mention of tacos her face brightened immediately up.
“For realzies?”
Adagio nodded and replied, “Yes, Sonata. For realzies. Now, let's go. The sooner we get home the sooner you can eat as many tacos as your stomach can hold!”
Sonata gasped and hugged Adagio very tight. “OH THANK YOU, Dagi! You're the bestest sister I could ever wish to have!”
Apparently she forgot right away how mean Aria was to her a couple of seconds ago. All she needed were tacos in order to be happy.
~~~
As they finally got home, Adagio first got rid of her food-stained clothes and told her sisters to do the same, so they could turn on the washing machine right away.
“As if I would be wearing this dress any longer. It's the worst”, Aria commented.
Adagio shot her another glare and pointed towards the laundry room.
“Whatever”, was all Aria said and did as Adagio told her to. Sonata was about to do the same, but Adagio put her hand on Sonata's shoulder, holding her back.
“Wait. I wasn't kidding when I said that I would give her a piece of my mind when we got back home.
I need you to get me something needed for Aria's punishment.”
Sonata gave her a confused look, then nodded. The eldest of the siren sisters whispered something into Sonata's ear. Sonata nodded once more in excitement. Adagio then left for the laundry room as well and got rid of her dirty dress. Aria just finished undressing and left for the living room without paying Adagio any mind.
After that, she checked to see if Aria had put any detergent in the washing machine.
'Of course she didn't bother!' Adagio thought to herself, groaning in annoyance as she took care of it herself.
Adagio left the laundry room and headed into the living room, only to see Aria sitting on the couch in her underwear watching one of her stupid TV shows.
Adagio couldn't believe how impertinent Aria was being. Her thoughts were interrupted briefly as Sonata walked by, bringing her clothes into the laundry room. Returning to the matter at hand, Adagio decided it was high time to teach her sister a lesson. She walked up to the TV, turned it off, and stood in front of it staring pointedly at Aria.
“Hey! I was watching that!” Aria complained.
“Right. And now you don't,” Adagio snapped back at her. Sonata got back from the laundry room and told Adagio that she turned on the washer.
“Good. But didn't you forget something, Sonata?” she asked her.
Sonata thought for a brief moment and then she remembered what Adagio told her to get.
“Oh yeah! I'll be right back!” she chirped and left for Adagio's room.
“What the fuck do you want from me, Adagio? Just get out of my line of sight so I can watch my show! Is that really too much to ask for after a defeat like that!?” Aria asked.
Adagio said nothing and waited for Sonata. Just then she came back, holding one of Adagio's belts in her hand. She gave it to Adagio and nearly bounced with excitement of what was about to come. Aria stared in disbelief at the belt in Adagio's hand.
“You're kidding. You've got to be kidding me, Adagio.”
“No, I'm NOT kidding. You finally pushed it too far by always treating Sonata like that! Yes, I understand that you are pissed because we lost. We all are. But that's not the point. You're always picking on her, bullying her and I have had more than enough of that immature bullshit of yours!”
Aria's heart now was pounding in her chest. As much as she was a nihilistic badass girl, she still didn't dare to stand up to Adagio. Instead, she chose to escape to her room and lock herself in until Adagio's anger evaporated.
“Oh no you don't!” Adagio yelled and went after her. She grabbed Aria by one of her pigtails and pulled her back.
"OW! Did you finally snap!?" Aria yelled in pain.
“You really need to understand that Sonata and I won't put up with your childish behavior anymore!”
Aria struggled against Adagio, but it was no use. Adagio was by far the strongest of the three sirens.
“OW! That hurts! Lemme go, you evil bitch!”
“Seriously? You, of all former unicorns Star Swirl banished to Earth are accusing ME of being evil!?”
Adagio pulled Aria to the dinner table and pushed her upper body onto it.
Sonata was giggling, but said nothing, she just enjoyed the show. Or rather, the thrill of anticipation.
Aria's body was now shivering in pure terror.
“Please, Adagio! Don't do it! I promise I'll be good from now on, I promise! Just don't beat me!”, she begged.
“I am quite sure that you'll improve your behavior from now on. And to make sure of that, you will need this... hm... correction,” Adagio coldly replied.
Then she pulled down her panties and Sonata gave Aria's exposed butt a fascinated look.
“Well, I may be the worst, but now you are getting the worst!” Sonata mocked her and giggled again.
“Quiet, Sonata. Just watch,” Adagio ordered.
Without any further ado, Adagio raised her belt and blew the first strike on Aria's butt.
Aria thought the pain would kill her. She never expected it to be this bad. Worse, Sonata watched and that was humiliating beyond imagination.
“OW! I'm sorry! Please, no more!”
Adagio ignored her pleas and continued her sister's spanking. She increased the force slightly with every blow and after ten or so, Aria decided to try and escape. She struggled and managed to turn herself around.
Adagio rolled her eyes, grabbed her by one of her pigtails and pulled her to the couch. There she forced Aria down on her lap and Sonata stared at them in amazement. After Adagio had struck several more blows to her sister's ass, Aria lost it completely. She left all dignity behind and started crying openly. And loudly.
“Please, Adagio! I'm sorry, I've learned my lesson! Please stop, I'm begging you! It hurts so bad!”
Adagio gave no answer until she was finished with her. Aria's ass now had a deep shade of pink and after some more strikes, Adagio finally ceased the beating and released Aria.
“Go to your room now. I do not want to see you again until tommorrow morning, understood?”
Aria quickly pulled up her panties.
“Yes, ma'am,” was all she said. She retreated in defeat, to her the second defeat this evening and hung her head. She slammed her door shut and locked it. Then Sonata spoke up.
“Wow. Remind me to never piss you off this badly.”
Adagio sighed and took the house phone.
“Let's not talk about this. Now, I promised you tacos and I intend to make good on that. What kind of tacos do you like again?”
