Author's Note

A little more fetishy than the last chapter, but should feel less dark, as this marks society having really accepted the casualness of beheading ponies. Expect later chapters to be much the same.
Diamond Mint and the flower trio:

Evil Enchantress

Not long after hearing of Filthy and Silver’s execution, Twilight was trying to explain to her friends that the strange Zebra was likely completely harmless.

Pinkie did her “Evil Enchantress” song for a bit, and Twilight was practically rolling her eyes.

“Psst, hey purple ass, these friends of yours are crazy. For a small price, me and my, uh, buddies can calm down everypony.” Whispered a shady-looking stallion head.

The rest of the mane 6, barely paying attention since Twilight was talking to a mere head, and were going on about how scary Zecora was.

“Name it.” Twilight whispered back.

“Let me lick that nice pussy and ass of yours. And no fartin' like the usual whores or I swear my buddies will chop your head off.” He replied casually. “Oh and, if you’re as good at magic as they say, maybe you can give a little severed head like me an orgasm?” He said, raising his eyebrows.

“I think I can, I’ll meet you later, promise.” Twilight said as everypony began panicking about Apple Bloom having run off.

“Okay, I’ll get to work, you best keep that promise...” The head said and winked to a nearby colt who acted to coordinate between the immobile mafiosos.

While the mane 6 were busy getting poison joke in their hooves, the head mafia identified the source of the paranoia: the flower trio. Preparations began immediately; they’d strike at night.
In the meantime, Twilight returned to the mafioso.

“Okay, this is kind of my first time besides a bit of family licking my rear clean that got a little...out of control sometimes when my parents were drunk, but I’ve studied it pretty well. And I found a spell that can tie your senses to mine, so you’ll feel everything, including my orgasm. How about that?” She asked with a smile.

“Hoo boy, purple ass, you are a treat, if a bit weird. Say, you come by and do this often, I can have my buddies do anythin’ ya need.” He replied.

“I’ll think about it.” Twilight said before wasting no time, casting the spell and sitting on his outstretched tongue.

He was quite rough with the initial licking, going deep inside her pussy, then ass, making the inexperienced unicorn go “Oooh!” in surprise. He meanwhile was breathing heavier than usual, as he could feel what it’s actually like to have a pussy being licked.

He played with her clit a bit before returning to penetrating each hole, making her moan loudly. He could barely hold back a moan himself, and soon her holes convulsed as a bit of her mare juices squirted onto his tongue.

“Oh fuuuuck!” Cried Twilight.

“Nnngh.” He replied as he felt it too.

The next few minutes were a rather awkward goodbye, as Twilight was unsure just what to say after a one-night stand with a bootycall for a favor.

The three mares were asleep in their beds the next morning when Diamond Mint levitated them quietly out into the early dawn streets. A little spell kept them dozing.

“Heh, like taking candy from a baby. Head mafia was the best idea I ever had.” She said as he came to the destination: the railroad tracks in a slight depression in the overall terrain, south of the station.

She laid out the mares with their necks on the rails, tied them up, and tied them to some strong posts before putting a silence shield around the area, making sure nopony would hear the screams.
giving Lily Valley a kick, eliciting a groggy moan and some blinking.

“Wake up, shithead.” Diamond said before sitting on the poor pink mare’s face.

“W-wha-mmmf!” She blinked again groggily before looking fearfully at Diamond. A resigned sigh could be heard as she realized she was being raped, and soon her tongue went to work on the asshole’s asshole.

Rose and Daisy stirred from the commotion, wiggling a bit and screaming for help.
Diamond chuckled and loudly farted a little into poor Lily’s mouth, making her faint.

“The horror! The horror!” Cried Rose. “Nopony will be at the shop to watch after the petunias!”
Diamond stared at her a moment. “...I suppose, now if you faint on me too, I swear to Celestia I will burn every one of those flowers.” She threatened cleverly with a smirk before moving over onto Rose.

Rose gulped and got to work vigorously licking the butthole while Lily opened her eyes.
Diamond let loose a long sputter down Rose’s throat with a sigh.

“This is awful!” Cried Daisy.

“And a little gross!” Continued Lily.

“Yep, you dumb bitches are gonna die as soon as the next train comes in...about half an hour. In the meantime, guess you can all enjoy a nice chat about how you shouldn’t spread rumors about zebras and, I dunno, which of my holes tastes better. Rose seems to think it’s my mint-flavored a-oooooh~ that’s the spot.” Diamond said, moaning.

“I’m gonna leave you once...mmmm~...Roselick here makes me cum. As for you, Lousy Lick Valley, just be glad I’m already killing you, I don’t like it when a pony faints under me.” She glared angrily and spat into Lily’s mouth, who forced herself to swallow in fear.

“Yuck!” Cried Daisy.

Rose continued at it passionately, tonguing Diamond’s wet folds. Diamond actually felt a little sorry for having to off such an obedient pony, and promptly raised Rose’s rear, spread the legs, and began licking at the pucker and pussy, making Rose eep.

For a while, lewd slurping and moans were the only things heard, as Daisy and Lily dared not interrupt the two.

“Mmm, back to the butt and give me a deep clean for the finale, please...” Diamond weakly asked towards the end.

Rose’s tongue went up her shitter in a hurry, making her shudder and moan as she squirted on the mare’s forehead, making Rose go crosseyed and smile. Rose herself moaned loudly, cumming and farting profusely a moment later as Diamond’s tongue gave her clit a final, weak lapping.

“I told her she’d be really gassy from all those beans.” Said a slightly disgusted, but chuckling, Daisy.

“Heh...ah, hard to find a living mare so graceful when she’s overpowered and little more than a sexy plaything. Would’ve preferred you didn’t let rip on me, but you did just wake up and all, and I suppose fair is fair.” She stated with a little smile.

Diamond then gave Rose’s butthole, which was still sputtering a little, a tender kiss, and gave her a hard spank, eliciting a squeal and a moan, before promptly getting up and trotting off. “Well, see ya I guess...”

“See ya...” Replied Rose, looking almost giddy as she was set down.

“So, what now?” Asked Lily.

“We wait for the train...” Said Daisy, grimly.

Rose smiled. “Hey, I never told you mares this, but I love you as more than just friends...how about we all kiss each other goodbye? I think we can reach each other over Lily, Daisy.”

The other two nodded, and Rose and Daisy’s lips met, beginning a passionate kiss while resting atop Lily’s head.

Rose formed a bit of a devious smirk and burped a ton into Daisy’s mouth, making her give a disgusted expression and pull away, a bit of the gas going in her nose, making her almost vomit.

Rose giggled and Lily laughed so hard she farted in little spurts over the course of half a minute while Daisy spat. “Blegh! That all came from Diamond’s ass! I could taste it! What happened to the days when I wasn't the only one who bothered holding it in unless it was really bad?”

“We eat almost nothing but fiber and you insisted we be ‘polite’ to each other and just ignore it when it ‘slipped out’. I just always figured we should have fun with it like the colts do. Speaking of which, we could use some fun right now; Lily, any left in the tank?” Rose smugly asked.

“...I’m sorry I've been a fuddy-duddy...” Daisy said with a frown.

“Nope, but I need to pee. And I’m not comfortable going...out here.” Replied Lily.

“I don’t think we’ve got many other options, and it’ll come out when the train comes either way...from now on, let’s just let it out, okay girls?” Daisy said with a smile.

“We can all go together!” Rose said enthusiastically.

Lily smiled. “Thanks, I feel a lot more comfortable now.“

“How about a kiss while we go, Lily?” Asked Daisy with a big smirk as she let out a short, but violent, fart.

Lily giggled and nodded, and Rose looked on with a smile as the two began making out and peeing together. It would almost be beautiful in a weird way if not for the sound of the oncoming train.

“The horror! Hmm...I've actually gotta poop, bet you two I can before it comes and still have time to kiss Lily too!” She said as the two let out their last spurts and broke the kiss.

“Just had to push it, huh? Typical...well, hurry up, unless you want your last memory of your butt to be needing a crap!” Daisy said, giving Rose a smirk as the two chuckled.

Rose started to strain in waves and Lily hyperventilated as the train got ever louder. It came into view on the top of the hill when she finally pushed out her turd with a short fart that could barely be heard over the train.

“Ha, time to spare!” She said as she turned to kiss the distressed Lily, burping first in her eye and then in her mouth as they locked lips. Lily didn’t seem to mind, doing her best to only take comfort in the affection.

Their tongues barely had time to mingle when, suddenly, the three were near-simultaneously sliced, a sharp pain and a weird sense of loss overcoming them as they went still with expressions of pain and fear.

Rose and Lily’s heads stayed together from their tongue-lock, while Daisy tumbled forward a bit.

There were no sounds but the rumbling of the train until well after it had passed, as their eyes started to look around.

Rose wiggled her tongue a little, and managed to very slightly break the kiss.

“You know I was hoping that it’d be instant...” Rose said.

“That’s pretty rare. We’re earth ponies, we’ll have months.” Replied Daisy.

“We’re legally dead now, so the flower shop belongs to my brother. This is awful!” Said Lily.

“Maybe he’ll take care of it...think we can get Diamond Mint in jail for this?” Asked Rose.

“Nope. My cousin, that head by our toilet, checked the law on it after his boyfriend chopped him for trying to pull out of a rimjob. Any crimes committed to a pony are forgiven when that pony loses their head, and it’s only murder if there’s a living witness.” Lily said before sighing.

“Huh, so that’s where he came from, ironic that now his only job is to lick buttholes and pussies clean.” Remarked Daisy.

“My brother was the boyfriend, he insisted on it as a fitting punishment. Fun guy, we've chatted a lot when I've had the shits and he’s super cool about farts and stuff. I’ll really miss that. Hope we don’t end up like him...” Rose said with a look of worry.

“Have I mentioned I love you girls, even when Rose is being...Rose?” Daisy said.

Rose smiled. “Thanks...we really should've become more than friends earlier...and who knows, if we’re lucky, we can just make out with each other in some cushy place and chat. I know how I’m gonna pass the time, how about you, Lily?” She said with a smirk and a lick of Lily’s face.

Lily blushed before the two get into the tongue wrestling match of their lives, leaving Daisy jealous.

Later that day, the mane 6 were confronting Zecora.

In the chaos, the flower trio’s heads spilled out from a cauldron. Daisy supported Zecora’s story while the other two were silent. Nopony seemed to be listening, and they even omitted the cauldron of severed heads in a thick goop from the evidence for Zecora being an evil enchantress.

Once the confusion was cleared, and Twilight promised to help, Zecora spoke up.

“Ah, but first, would you like to hear of a special brew of 3 lost souls and honeydew?” The zebra asked.

“I suppose...” Replied Twilight.
Apple Bloom righted the cauldron in the corner and put the flower trio’s heads back in it. Not all had spilled out.

“This here stew gives you the memories of the heads that’re in it, and keeps ‘em alive. They’re a little melodramatic if ya ask me, whinin’ 'bout gettin’ their heads chopped off and bein’ humiliated.” Apple Bloom said, offering a cup to Twilight.

“It was awful!” Insisted Lily while Rose and Daisy made out passionately.

“Oh, I may have had something to do with that, whoops.” She said before taking a sip, pupils dilating as she remembered the entire lives of the flower trio up until their heads came off.

“Whoa...okay, I’m here now...it felt like it’s been years. It actually was kinda awful, but you three had it coming, and Diamond was nothing compared to my brother.” She said, chuckling, before giving the empty cup back.

“...glad Big Mac don’t do that.” Said Apple Bloom with a disgusted look.

“How long you plan on keeping the heads? They don’t seem like very good company, and three is more than you could have to uh...pleasure yourself with.” Twilight asked.

“The stew is for profit, and in a year or two, when that’s gone, I’ll off it. But for now, I am entertained by these 3 heads fate has pained.” Zecora rhymed in response.

They then went off to right some wrongs, which was a lot easier without the flower trio running in panic.
