It was a rare occurrence for the siren to notice when she does wrong, let alone regret doing it. She had always considered herself a creature of pure, logical conclusions and appropriate actions. What's to regret when everything you did was perfectly logical?

Logical to other megalomaniacs and sociopaths, that is.

But the following week since the work yard event had been a confusing blur to Adagio. Every day had been shockingly peaceful afterwards, with not a single inmate trying to do anything. Everything had return back to normal, as if nobody had the full intent to carry out their threats.

And it aggravated her to no end. Adagio had utterly despise people who didn't carry out what they said, especially if it were a threat. It made it seem as if all her taunting and manipulating—which was the most likely cause for said threats—had gone to waste. While she had vehemently deterred from living by petty philosophies, even she realized that the calm before a storm would always be the… um… calmest time. But as the days went by and surprising lack of sex increased, Adagio had forgotten the event as well, reluctantly accepting the peace that had occurred in the prison.

But all of that changed when the bug queen arrived.

"… Excuse me?" said the siren, her face portraying her confusion with unrelenting zeal as she stared at the carapace coated companion.

"Let me be your bitch." Her replied was as curt as it was ridiculous.

The siren was continued to stare at the prisoner, this time with a expression of disbelief chiseled into her features. "You want to be… my bitch?"

"I didn't know you were deaf as well, siren," Nightmare Moon grumbled off to the side, lazily downing her daily dosage of demented dinner for digestion.

"Quiet, you," Adagio hissed at the shadow mare. Her gaze returned to the bug hybrid. "And what makes you think I need one? As you can see, I already have a bitch." In an instant, Adagio roughly grabbed Nightmare Moon by the hip, before plopping the regal mare in her lap and began molesting her melon-sized mammaries. "Isn't that right, bitch?" the siren whisper huskily in the woman's ear, ever so lightly tickling the poll with her hot breath.

The forlorn princess stifled a hearty groan, silently cursing herself for being aroused already. Sadly, the despicable week of no sex had took its toll on the mare, whittling her arousal resistance while her sexual need grew infuriatingly high. Naturally, she would have masturbated rigorously, roughly, and rampantly every night and be done with it, but with the arrival of Adagio her satisfaction from solo play had diminished greatly, making her wish she had listen to the warnings more carefully.

Once you go siren, you never go back.

"G-get off me, you harlot!" The black coated mare tried her best to resist the alluring touch of the sexual assailant, but her attempt was as halfhearted as it was empty. She simply couldn't take another day without some form of touch from the singer, and it drove the mare insane with malicious hate that she had became so needy of the provocative woman.

"Oh Nightly, if that's the best insult you can come up with, then you're more desperate than I imagined," the siren replied, a sinister grin across her features. Her hands roamed the raven fields of Nightmare's flesh under the paper-thin fabric, molesting the alicorn's body thoroughly. Her expert hands running on autopilot across the terrain, knowing exactly how to turn the royal mare into a bitch named Nightmare. Every grace and every touch from the singer lit a spark of pure bliss to the mare's senses, burning brighter and brighter as the assault continued with no end in sight.

"Why not 'fondling cheese-puff monster'." The siren roughly groped one of the mare's abundant mounds.

"Or why not 'The one who fucks'?" her hand plunged into the gasping deity's trousers, easily slipping into her dripping wet panties before relentlessly rubbing her puffy labia.

Adagio hovered over her victim's neck, her breath matting the fur in several places. "Or even 'nympocampus', if you want to get fancy." She bit down on the vulnerable flesh, drawing a pleasure-filled hiss from the mare along with blood, which she greedily lapped up. Nightmare twitched and shiver rapidly, her ragged breaths coming out in hasty, desperate pants, a signal of her oncoming climax; a signal Adagio read all too clearly. The siren switched off, retracting her soaked hand from the mare's knickers and sending it into Nightmare's mouth, forcing her to taste her womanly juices.

The submissive night mare happily took in the invading digits, too drunk on her blinding euphoria to oppose, even suppressing a reflexive gag when the siren reached her throat. Her own hands seized her longing nipples, desperately trying to gain every ounce of pleasure to rush to her climatic climax.

The forsaken deity didn't have to wait long, for her muscles began to contract with near painful intensity as she felt her senses scraping inches away from the edge; a few more seconds and her sexual crucible would be over in a blaze of explosive euphoria.

"BUT"—the siren instantaneously ceased her actions, turned the alicorn towards her and held her in a soul piercing gaze—"there is only one proper title that you could possibly give to me: Master."

Nightmare Moon was left gasping, shuddering in rage, hate, malice, and unending bloodlust as she was not just stripped of her rightful climax, but dragged down from her euphoric end kicking and screaming with that final word. "Y-you…" Nightmare slumped over, all the burning emotions the mare felt bombarding her unabatedly, before she lost all consciousness in the siren's arms. Adagio turned her attention at the bug prisoner, dropping Nightmare on the cold floor like a worthless rag doll.

"So answer me, Chrysalis, do you still wish to be my bitch?" The siren's burning gaze torn into the mare like a raging inferno through a silly lad not listening up to the warning signs.

"When do I start… Master~"

"Ugh, what happened? Where am I? Am I not in Tartarus anymore?" Nightmare Moon said as she groggily rose to a sitting position.

"Ha, you wish," said a voice that was immediately recognized, returning all the memories of before she was knocked unconscious. Her blood began to boil brutally, the remembrance of that debacle only sending the mare into a frenzy. Her senses returned shortly after, and laying beside her, wearing nothing but the clothes she was born with, was the instrument and rapidly growing epitome of her eternal torment. "Did you sleep well?"

Nightmare Moon's arm reared back ferociously, primed and ready to send the relentlessly cocky siren to the moon. "YOU WRETCHED—"

"Well, well, well. It's seems my precious little satellite has finally risen once again." The familiar metallic, synthesized tone to the new voice massacred all of Nightmare's rage, a fresh wave of fear quickly taking it's place. She turned around slowly, fearing that the person was already behind her. Pass the bars of her cell, stood GLaDOS, in all her dictatorial glory. Her glowing yellow eyes stared her down, burning Nightmare's very being to the core, but even still she was unable to look away. "I hope I didn't interrupt anything."

"N-n-no, M-mistress Gl—"

"Oh, wait, I've stopped caring… if I had cared in the first place, that is. I have no time to linger about with filth like you two." As Nightmare watched her, she noticed GLaDOS holding a black leather leash leading to some outside of her visible range.

"GAH! LET ME GO, YOU INSUFFERABLE WASTE OF—GAAAAAK!" GLaDOS kicked whatever was beside her, the accompanied dull thud hitting the ground ensured Nightmare that whatever was kicked was hurt badly.

"What did I say, prisoner #9420: do not talk back to me. Oh, but you'll learn that soon enough. I've heard you love learning, isn't that right, Midnight Sparkle?" GLaDOS picked the girl up, revealing a dark purple girl with another three shades of violent going through her flame-like hair. The aforementioned black leash attached to a collar on her neck.

"Y-you bitc—AAAAAAAAH!"

"Oh dear, I must have been wrong in my assumption that someone wasn't going to be an idiot. How surprising. But, rare prisoners like you are too precious to release with the other inmates. You'll need special attention. I'm going to have to break you in, just like I did with that Sunset girl." Without a further notion, the warden went off, her prisoner dragged along with her.

Nightmare felt her body relax with zealous relief, she herself not even knowing that she was clinching every muscle at the same time. "You got lucky today, siren, but don't think you're safe," she said, not even turning to her cellmate as she buried her face into the bed.

Yet the siren sat in silence, her mind not even registering the threat as it replayed what had just transpired, leaving no space in her brain but for only one thought.

Sunset was in the prison.
