Without further ado, let's get into it.

Sunset Shimmer stands in her front room, giving her friends a steady look.

"Okay, so..." Rainbow Dash begins, her voices strained, placing a hand to her temples. "Lemme make sure we're all on the same page here... Adagio Dazzle hypnotized Fluttershy into hypnotizing you into hypnotizing us... And then having sex with us?"

Sunset looks at Fluttershy, the girl cringing under her gaze, and nods.

"There were other things, but yeah, you've got the gist of it."

Rainbow Dash nods as well, leaning back in the armchair. "Okay." she says weakly. "Thanks."

The others merely sit in shocked silence.

"This explains so much." Applejack says, finally. Rarity nods, looking down at her feet, her face red.

"Y-You..." she stammers, before trailing off. "Fuck, I-" With a squeak, one of Rarity's hands shoots to her mouth... The other trails down to her crotch. She sits there, stock-still, her eyes glued to her feet, until Pinkie Pie speaks.

Her hair dangerously approaching flat, Pinkie Pie stares Sunset down. "After you came over, I masturbated again." she says, her voice even. "And even though something deep down told me it was good... I still called my parents up and confessed. We had a long talk, Sunset. A really long talk."

Sunset nods.

"I know I've done horrible things to you." she says softly. "And I don't have any excuses. You see; Fluttershy only told me to hypnotize you. Sure, she built it into a fetish, but it was me who made you like masturbating, and who made Rarity like swearing. I understand if you won't ever forgive me." she gazes at each of them in turn, her face set in a determined grimace. "But even if you can't... I'm hoping you'll help me. Adagio needs to be stopped, and we've got a perfect opportunity to do it; she's coming in a few days, and she'll be taking a tour. She'll be checking up on each of you, and she'll be expecting six perfectly entranced girls, ready for her to take out every disgusting little revenge fantasy she's ever had out on. When she does, we'll be able to stop her."

The others nod, and Applejack stands, holding out a fist.

"Sunset, you nearly hurt me. But you stopped. And that counts fer somethin' to me. You did hurt mah friends, and you an' Ah are gonna have a talk about that after this. But you're right. No matter what, we're gonna stop Adagio."

"You've made mistakes before." Dash says. "Sure, this one was pretty big. But you're still my friend. And I'm not gonna leave you hanging, not when you need me like this." Slowly, she gets to her feet as well, stacking her fist on top of her friend's.

Rarity is the next to add her fist to the pile. "We will speak after everyone else has left." she says simply. "I don't want to act un-ladylike when others can see. But know that I'll help you stop that... bitch."

Fluttershy silently approaches and, not meeting Sunset's eyes, adds her fist to the stack.

A solid minute later, Pinkie stands, wordlessly adds her fist, and gives Sunset the most serious look she's ever seen Pinkie wear.

"I'll stay with Rarity." she says softly. "I want to talk to you, too." Rarity nods, and they break apart, the six girls standing in the room.

"Ah'll be headin' back to the farm now." Applejack says. "Anythin' there ya need, Sunset?"

"Some rope." Sunset says. "Bring it over tomorrow. I know today's been... Eventful."

With a nod, Applejack leaves, the door shutting behind her.
Rainbow is the next one to leave, her hand making a phone shape next to one of her ears as she mouths 'call me' to Fluttershy. Soon, the dual 'thrum' of truck and motorcycle engines cuts through the silence.
When they fade, Fluttershy opens the door. Without a word, she steps out, leaving Sunset alone with Rarity and Pinkie Pie.

Sunset turns to them, her arms spread, her eyes downcast.

"If you're going to do anything," she says calmly. "do it now. I deserve everything you can throw at me, and more."

A blur of white, and Rarity's hand meets Sunset's face in an open-palmed slap. Sunset accepts the blow, her head angled to the side and a breath escaping her. She stands there, Rarity's heavy breathing the only sound in the room.

"Sunset." Pinkie says softly. "We're ready now."

Sunset looks up, and gapes; Rarity and Pinkie are both stripped to their underwear, the garments hugging their assets snugly, leaving almost nothing to the imagination.

"Wha... I don't-" Sunset splutters, before Pinkie cuts her off, pressing a finger to Sunset's lips.

"Sunset." she says, and the girl notices with a jolt of surprise that Pinkie's hair is back to its usual state of wild, poofy disarray. "My parents, when I talked to them, told me that they weren't angry, or ashamed of me... They told me that masturbation was a normal thing, and that they were glad I talked to them about it. They almost sounded proud." Pinkie lets out a tiny giggle. "I'd been missing out on a world of kinky fun, and you were the one to introduce me to it. It wasn't very nice not to ask me first..." her face grows serious again, and she pokes Sunset in the chest with her free hand. "But... I forgive you. You're still my friend. And I want to thank you, for helping me find out about sex in a safe, fun way. Oh, and for the bigger boobs."

Sunset nods, turning to Rarity, who stands there, holding her hands together over her chest.

"Sunset..." she says. "What you did to me was degrading... It was against my will, and it brought me down to a base, sexual level I've never been forced to before." Slowly, a small smile makes its way onto Rarity's face. "And... I loved it."

"What."

"I did!" Rarity cries. "I loved it. It was so crass... So beneath me... Fuck me, but I loved it." she rushes to Sunset, hugging her close. "I know it's wrong... I know, after what you've been through, that it's selfish to do this to you... But I don't care. Oh, Sunset, please... do it again!"

Sunset takes a step back, utterly shocked.

"N...No." she finally says, shaking her head. "I-I can't. I'm sorry, girls. I've fucked with your heads more than I thought..." slowly, she sits down in a chair, her head in her hands. "G-Get dressed. Please. Now. Don't do this."

She sits there, anticipating something, anything... And then Rarity sighs.

"I'm sorry, Sunset." she says softly. "It was selfish of me to act as I did. I... I lost control. I can see how hard this is for you."

"I can't." Pinkie says. Rarity shoots her a glare, and she shrugs.

"What?" she protests. "It's just fucking! It's not like she's hypnotizing us again! Not that I'd be opposed to that..."

"Pinkie." Sunset says, eyes still averted. "I just got done being the bad guy again. I practically raped both of you, and almost raped Applejack. I can't do that again." Sunset sniffles, her fist clenching. "Maybe... maybe, after all this is done... We'll talk. But until then... Please get out of my house before things get out of hand."

With a heavy sigh from both girls, the door opens... and then closes again.

"Dear Celestia, what did I do to them?" Sunset breathes, leaning back in her chair. "Even after I told them... They still want to be my friend..." after a long while, Sunset sighs, standing. It didn't matter right now. She takes a deep breath, then lets it out, her face even. All she needed to do was beat Adagio. Then she could worry about the rest.

Vinyl Scratch walks through the door of her home. With a whistle, she calls out to Octavia...

"Mistress is here." the girl replies, and Vinyl nods, stripping unceremoniously as she heads into the kitchen. No servant - no good servant, at least - was clothed in her Mistress's home. she approaches the kitchen, whistling a short, complex tune. Octavia's voice murmurs something, before raising in another call.

"Mistress says some food would be lovely!"

Nodding to herself, Vinyl begins her work.
Mistress had explained it all to her a few days ago. She'd been drained of her powers... But, thankfully, she was able to eat human food. Thus, Vinyl had taken the job of being her Mistress's live-in cook. She existed to serve, after all, and she was an excellent chef.

One of her fellow slaves walks into the kitchen and bows, bending over at the waist, her tits jiggling.

"I will assist Vinyl in cooking food." Sonata Dusk says, her voice blank and emotionless. Vinyl nods, indicating various cupboards with her hands. As Sonata rushes around, mindlessly obeying, Vinyl says a quick prayer of thanks to her Mistress for letting her keep most of her free will. With the cupboards - and her fridge - open, Vinyl points to a myriad of ingredients; spices, pans, spatulas, and a slab of meat sitting in her fridge's bottom drawer.

Vinyl and Octavia didn't used to eat meat. Then Mistress had told them to eat it, and they ate meat now, just like she did.
Soon, the meat is cut, the excess stored, and a steak sizzles on the stove.

"We are allowed to eat this meal with her!" Octavia calls. "Praise Mistress for her mercy, as we praise her in all things!"

With a nod, Vinyl sets Sonata to cut and prepare two more steaks, which sizzle along with the first.

Footsteps, labored and heavy, accompany a low sigh.

"Morning, mute." Aria says, her tone resigned and weary, as she enters the kitchen. "Making our beloved Mistress a good meal?"

Vinyl nods, saying a quick prayer of thanks to her Mistress for taking away enough of her free will to make her enjoy servitude, rather than force her body to obey against her will, like Aria's. As she watches, the girl slowly begins to undress, swaying her hips and chest as she begins stripteasing the DJ.

"Mistress has commanded me to provide you with 'entertainment' while you cook for her." Aria says, not meeting Vinyl's steady gaze, concealed as her eyes were behind her shades. "A reward for your... And my... Loyal service."

Vinyl nods, enjoying the show; where Sonata's breasts were, paradoxically, full, round, gigantic, and perky at the same time, Adagio's were flat, a set of modest B-cups that barely swayed as she danced. However, what the broken girl lacked in breast size, she made up for in waistline; her hips were deliciously plump, rounding off into a perfect bubble-butt that sways and jiggles tantalizingly as she slowly pulls her panties down, a bit of wetness betraying her.

"I've been..." Aria sighs. "I've been 'allowed' to feel arousal from this situation." she is fully nude now, dancing enticingly as Vinyl leans back against a cabinet, admiring her. Mistress had given her a show, and she would enjoy it.

Soon, though, the steaks are done, and Vinyl dismisses Aria with a wave and a whistle. The girl breathes a heavy sigh of relief, gazing into Vinyl's eyes. Desperation filling them, Aria Blaze mouths two words, before turning and, still fully nude, entering the bedroom.
Vinyl returns to her cooking, whistling a merry tune as she works. The steaks are cut, checked, and approved; rare, just how Mistress - and, by extension, Vinyl and Octavia - like them.
The door to one of Mistress's rooms - the one Octavia knew to call hers when Mistress wasn't around - is open, and a low moan emanates from inside. Gently knocking on the open door, Vinyl receives a gift.

"Inside." Mistress's voice rings out, and Vinyl enters, swimming in bliss. Just hearing her Mistress's divine voice was enough to make her cum, and her juices stained her thighs, a mark of pride, a sign that she was a good slave. Octavia is on the bed, heavy breasts heaving, panting with pleasure as Mistress finger-fucks her cunt eagerly, giving Vinyl a smile.

Mistress...

There was no way to describe her perfection using words, but Vinyl knew a few that came close. Where Aria's hips were wonderful, Adagio Dazzle's were ________. Where Sonata's breasts were inviting and enticing, Adagio Dazzle's were ________. Simply put, she was perfection incarnate. Divinity given flesh. She was music in a body, rhythm and rhyme and melody in every single atom of her absolutely impeccable being.
She was Mistress.

Vinyl sets the steaks down on a table and sits, eagerly awaiting that voice, the angelic chorus that carried orders and praise and censure all in the same wonderful song.
Nothing happens, not for a long time. When Octavia cums, singing praises to her Mistress every second, she finally turns and, without pomp or ceremony, speaks.

"We'll eat now. You two will enjoy the taste of meat, as you always do, because it's what I eat, and you love me completely."

With eager nods, the two girls begin eating, devouring the steak as voraciously as their Mistress.

As Vinyl eats, she reflects...
The Dazzlings had certainly changed since she'd helped those accursed Rainbooms defeat her Mistress. Sonata was so quiet and obedient now, instead of her usual spasmodic and frenetic self. And Aria... she was sadder. Much sadder.
Maybe it was pity. Maybe it was because Vinyl Scratch was a good person. Maybe it was because, deep down, the real Vinyl Scratch was still in there somewhere.
Whatever the reason, Vinyl resolves not to tell Mistress what she'd seen; that the words Aria had mouthed were 'Help me.'

Author's Note

I was going to make a joke about how something was up, as I'd planned to release this thing a week after the previous chapter. I'd had almost all of it done...
And then I got strep throat.
Yeah, that'll teach me to plan around being healthy. You get another three-week pause. At this point, it's not even something I need to apologize for; it's just what happens.

Planning, almost-sex - Got you there, didn't I? - and at last our villains show their faces! Or face, as Aria and Sonata seem to be...
Indisposed.
