It's Halloween Night and two sisters will cross the line that shouldn't be crossed!

Contest Entry for Wincest's Cloptober Contest

In the alt-universe of EQG, Blitz doesn't want to do anything for Halloween because she feels she's too old. As her parents and aunts are away, her big sister, Spark, appears and wants to spend Halloween with her dear little sister. These two sisters will cross the line that shouldn't be crossed...

It's a one-off spin-off fic part of my own fic series, but don't worry. Someone explains it super quickly in the story about past events. Even though this is a clopfic, this clopfic is canon to the main fic series because of the ending.

Happy Halloween

In this alt-universe of EQG, it was Halloween Night, and the town called Cantorlot was bustling with activity. The citizens were either getting dressed up for trick-or-treating or heading out to a party. In a specific corner of the town, however, a large house stood out like a sore thumb as there were no decorations in the yard...until a rainbow blur sped around the yard, putting up spooky-themed decorations everywhere.

"That looks good, sweet pea." said a chestnut-haired woman from the front porch, wearing a blue shirt and jeans. She walked out and met with the one who set up the decorations. She rubbed and messed up the girl's rainbow hair, which had a black stripe. "Ten seconds flat! Not bad, Blitz! While in your pony-human hybrid form, you can sure move fast!"

The girl, known as Blitz, wearing a purple jacket, blue shirt, and runner leggings, brushed her Mother's hand away. "Mom, stop it. I'm not little anymore. I'm an adult now! I'm nineteen!" she complained.

Her mother chuckled. "Oh, come on, you know I can't help it," she teased. "After all, you ARE my daughter; daughters are their mothers' most precious treasures." Two walked back into the house, but she playfully punched her daughter in the shoulder. "Besides, you are still living with us with one of your girlfriends, Lucy, so I have full rights to keep treating you like a kid. It's a mother's privilege."

"But Mom-"

"No buts! Your stubbornness might come from me, but it's my right as a parent to keep being a pain. Now!" she closed the door, and the two entered the living room, seeing the others in their costumes. The two could see four mascot versions of Twilight's friends as they wobbled around the room like they were lost. Blitz's mother sighed. "Care to help me with my idiot friends? They seemed to forget to add the eyeholes, and they're all bumping into the furniture."

Blitz snickered and went to work as she became a rainbow blur again. She removed the headpieces and added eyeholes to the neck parts, making it easy for the four women to see. Each woman was this universe's human counterpart of AJ, Pinkie, Rarity, and Fluttershy.

"Dear heavens! I can see again!" This universe Rarity gasped as she noticed the headpiece was off. "Oh, thank the lord!"

"I'm so glad we can see where we're goin'!" This universe AJ groaned. She looked over to Blitz and tipped her trucker hat in gratitude. "Thanks for the help, kiddo."

Blitz giggled. "No problem, Aunt AJ," she said.

This universe Fluttershy sat on the sofa and sighed with relief. "Finally...we can see, and I can breathe too," she said in her timid, shy voice.

Soon, joining human Fluttershy's side was this universe Pinkie, who jumped on the couch and wrapped her arms around the timid woman. "But it was fun bumping into things! It was like bumper cars without the car!" she beamed, bouncing in place.

"Penny!" said everyone in the room.

Penny shrugged. "What? It was!" she defended. She turned to each friend, naming them: "Rachel, Faith, April, but we call AJ because her last name ends with J. And you might not guess it, but the brown-haired woman is Dashie! That's her nickname, but her full name is Dashiell! She's not here right now, but Dashie's wife is Twilah!" she snorted.

Everyone looked at each other, wondering why Penny was acting weird, which they quickly shrugged off because it was Penny.

Blitz shook her head in happiness. "Aunt Penny. You changed ever since-"

Blitz couldn't finish as Penny was already up in her face and smiling, and she started to ramble. "Yeah, ever since we traveled to Equestria after you ran off to fight Rainbow Sun Dawn alone with your twin sister, Braver, in the multiverse forest thingy!" she turned to...the readers? Huh? "Quick run down for new readers as you read this one-off/spin-off! See! Dashie and Twilah went to see a rainbow comet years ago in the forest, and the comet dropped rainbow shards, which made those two meet their Equestrian counterparts and have one huge multiverse adventure with other counterparts!" she raised her arms in the air, excited. "It ended with them saving Blitz here and her twin sister, Braver! Blitz lived here with our two friends, and Braver went to live with Twi and Dash! Then, ten years later, an evil-crazed woman called Rainbow Sun Dawn, who looks like an older Lucy, Blitz's friend and love interest, AND this universe, Luster Dawn. The evil Dawn came looking for the twins to eat them and restart the multiverse! Many things happened, like our Sunset being able to transform into an anthro version of Equestrian Sunset or how Wallflower became a forest Nymph! Those two are Blitz's childhood friends and then girlfriends, too. I think time-travel happened behind the scenes for future events, and then learning Blitz and Braver had an older sister called Spark!" she took a big breath.

"SparkisacloneversionofaaltuniverseofTwilightandDash.See,BlitzandBraveraren'ttheclonesliketheythoughtbutslimesthattooktheDNAfromSparkwhentheyfedoffhermagicalenergytostayalive,whichbythewayisthereasonSparkseesthosetwoasssiters!Anyway,thetwinsdiedandSparkhadadventureofherownasshefoughttherealbigbadcalledFayth,whousedanotheraltversionofTwilahandDashietoopenawaytoaplacecalledElyndrawherethereisavastgoldentreewherethereisabook.ThatbookcanrewritethewholemultiverseintothateveryouwantbutFaythwantstoendthewholemultiverse!"

Penny was gasping for air as the others tried to follow her words.

"ANYWAY!SparkbeatFaythandcametotermsthatshemightbeaclonebutsheherownpersonandtookthebestpartsfromourfriendsandTwilightandDashwhenshewatchedhersistersgrowingupthroughtheireyes.Itsbeen..three y-years...now....and....and....I realized that wasn't quick...ugh!"

She fell over and passed out.

The others looked at the passed-out Penny. Soon, an AI hologram version of baby Spike appeared.

"Yo Penny, You Alright?" Spike asked.

Everyone watched as Penny started to form at the mouth, making Dashie ask AI Spike if Penny would be all right. Spike did a quick scan, and the results showed.

"Yeah, she gonna be fine."

Dashie shrugged. "Good enough for me!"

Everyone ignored Penny and returned to what they had been doing before: getting ready for a Halloween party in the town's park.

Rachel was handed back the mascot's head, and she couldn't help but smile at the silly-looking Rarity face. "Thanks for the help, Blitz." she lowered her head and looked at her. "Shame you aren't joining us at the party, darling. Why is that?"

Before Blitz could answer, Dashie slammed a Rainbow Dash mascot's head over her head and replied, "Get this! She says she's too old for trick-or-treating or dressing up in costumes for Halloween!" She pulled the head off and laughed as she saw her daughter blushing. "Haha, she's all embarrassed!"

Faith giggled, and April nudged Dashie. "Come on, Dashie, leave the poor girl alone," she said.

April was right. Blitz was getting embarrassed by her mom. It wasn't her fault she didn't like dressing up and going trick-or-treating anymore. It also felt wrong for a nineteen-year-old to dress up and collect candy.

"What? I'm not teasing. I'm just saying," Dashie argued. She smirked and hugged her daughter. "I remember when you came to live with us, and your first Halloween ever in this universe, you dressed up as Flare, aka Supermare, and didn't want to stop trick-or-treating, even if you ate more than your body weight in candy." She snickered. "You were a cute little bugger. Then you hit puberty, and now you are lame." Dashie tsk loudly and shook her head, but Blitz knew she was messing with her.

"MOM!"

Everyone burst out laughing as if they were a big, happy family. Blitz crossed her arms as she felt her cheeks turn pink. "I'm not a kid anymore, mom. I'm an adult!" she grumbled.

"So what's the big deal?" Dashie asked.

Blitz raised her arms in the air and groaned. "I can't go trick-or-treating or wear an outfit because I'm an adult!"

Dashie looked around the room, seeing all the adults and herself. "We're all adults, and we're still doing it."

Blitz groaned again, "Mom, you and the others are like...a different type of adult." she waved her hand at them, but this rubbed Dashie the wrong way.

"How is that different?!" Dashie huffed, not happy her daughter was calling her a weird type of adult.

Blitz looked away with her arms behind her head. "Well...you, Mom, and your friends are like-"

Dashie crossed her arms, looking mad now.

"Blitz, don't you dare call us what I think you're going to call us," Dashie warned.

Blitz didn't listen. She was going to say it.

"You're boomers!"

There was silence. Everyone, even Penny, who was still passed out, was shocked to hear Blitz's statement. It was true. They were old but not that old. Dashie rolled up her sleeves and marched over to Blitz.

"We are in our early thirties! We are not that old!" she shouted, looking madder than a wasp.

Blitz, however, didn't care. She had a point to make, and she wasn't stopping. "Sorry, Mom, but the evidence is there. You act like boomers, and it's embarrassing."

Dashie was red in the face, and so lost for words that she would lose her temper soon. Luckily, someone entered the room, stopping the fight before it could get ugly.

"Alright, is everyone ready to go?"

Everyone looked at the source of the voice and smiled as they saw the mascot version of Twilight standing at the living room's entrance. Twilah removed the head mask and coughed before she spoke again.

"What's going on? Dashie, why aren't you in your costume yet?"

Before Dashie could answer her wife, Blitz saw this as a chance to get back at her Mom. "Mom is being a boomer and embarrassing me because I'm not dressing up for Halloween!"

Dashie glared at her daughter for a moment. "Oh, shut it, you little brat," she grumbled.

Twilah wasn't having it, though. She put her hands on her hips and stared at her wife, looking unimpressed. Dashie could feel the glare from Twilah and soon heard her friends laughing at her as Twilah pointed at her to come to her.

"Dashie, come here."

"What?"

"NOW."

With a loud groan, Dashie walked over to Twilah, and Twilah took the Rainbow Dash's head and slammed it over Dashie's head. Twilah held her wife's head in her hooves, smiling.

"Blitz is old enough to do whatever she wants, and if she doesn't want to wear a costume, then it's okay." Twilah kissed the side of the Rainbow Dash mascot's head. "You must remember that our little girl isn't little anymore. Come on, get ready, and we can head out and enjoy the night."

Dashie sighed but nodded. Twilah was right; it was okay if their daughter didn't want to dress up for Halloween anymore. She turned and saw Blitz and the others trying to wake Penny up. Dashie had a sad smile as she looked at her daughter.

"I know, but why does it feel so sad? Our little girl is growing up."

"I know, sweetie. Just remember the good times and enjoy the time we have lef-" Twilah suddenly had a coughing fit, and Dashie and everyone looked at her, looking sad and worried. As the coughing stopped, Dashie placed her hands on her wife's shoulders, ensuring she was okay.

"Twilah..."

Twilah knew why Dashie and the others were worried, but she didn't want her sickness to ruin the night. It was Halloween.

"I'm fine, sweetie," Twilah said, waving her hoof, but she couldn't help coughing again. She felt the worry coming from Dashie and her friends, and she had to change the subject. "Come on, let's head out. It's gonna be a great Halloween."

Everyone knew that Twilah was only saying that to keep them from worrying, but they couldn't stay down and gloomy forever. They wanted to have a great time tonight with her.

After some time, Dashie was in a complete Rainbow Dash mascot suit, and everyone else was ready. Blitz walked everyone to the door and watched April carry a still-passed-out Penny out of the house while Faith and Rachel followed. Her parents stopped at the door and faced her.

"Well, since you don't want to do trick-or-treating or go to a Halloween party, why not give out candy to the little trick-or-treaters?" Dashie asked, pointing to the giant bag of candy by the front door.

Blitz shook her head and sighed, "Mom, I don't think-"

Before Dashie could say something, Twilah stepped in, knowing her wife would say something to annoy their daughter. "Sweetie, let her decide. If she wants to give out candy, that's okay. If she doesn't, that's fine too. You know, she might have other plans," she said.

The Rainbow Dash mascot rolled its eyes, but Dashie understood. "Okay, I get it. I'll shut up now," she grumbled.

Blitz waved goodbye to her parents and watched them walk down the street, heading to the town's park. Dashie turned to Twilah and asked her a question.

"We're not boomers, right?"

Twilah laughed as she answered. "Dashie, you don't know how to work a smart thermostat."

Blitz watched as she heard her Mother mumbling loudly. Soon, they were gone; Blitz closed the door and leaned against it, letting out a long, heavy sigh.

"What am I going to do tonight?"

She kicked herself off the wall and took out her phone. She was going to call someone, but behind her, darkness appeared, and it slowly formed into an Alicorn anthro figure, its eyes glowing as it raised its arm into the air like it was going to attack.

Blitz could feel the presence, but it was too late. Her head was stuffed into a rainbow jacket, and her vision turned black.
"Hey!"

Blitz's face went red as she felt the softness of breasts and smelled the fragrance of her assailant. She knew who was holding her.

"SPARK!?"

The zipper was pulled down, making Blitz's head poking out of the jacket. Spark, her older sister, couldn't help but laugh at her poor little sister.

"Hey, Blitzy! It's been a long time since we've seen each other, and happy Halloween, little sister!" Spark smiled.

Blitz crossed her arms, and with a pissed-off look, she welcomed her older sister the best way she could.

"Screw you sis."

Spark couldn't help but squish her breast against Blitz's cheeks, giggling.

"I'm sorry, but I can't help but mess with my cute, awesome, cool, amazing little sister!"

"I'm not cute!"

Spark squeezed Blitz harder, feeling her little sister's wings trying to spread out. "Oh, yes, you are! And I can see you happy to see me again going off by your-"

Blitz broke free from her big sister's softness and tried to lower her wings. "Shut it, you siscon!!!" she snapped, turning away.

Spark giggled. "Come on, Blitzy, you know I'm just joking."

Blitz wasn't amused, and Spark knew her sister wasn't happy to see her.
"Oh, come on. Don't be like that."

Blitz couldn't stay mad as she was happy to see her big sister again. She sighed and shrugged. "It's okay, sis. So, how long are you able to stay in this universe? Aren't you dealing with Fayth?"

Spark creeps closer to Blitz as she makes kissing faces. "Aww, you miss your big sis. You can't stay mad at me, and Fayth isn't a problem right now. Still can't find her after I gave her a warning about hurting my sweet little sisters or the rest of my family and friends."

Blitz placed her hand on Spark's kissing face, stopping her. "And here I thought I wouldn't get a visit from my big sister this Halloween. I thought you had a multiverse to care for," Blitz said.

"I'm still protecting it, but I can take a break, and besides, I couldn't miss my little sister dressing up in a cute Halloween outfit!" Spark stood and started to drool as she began to picture Blitz in a cute Halloween outfit.

"Sis, no! Don't you dare!"

"I have so many cute outfits in mind for you! Oh, the choices!" Spark swooned, rubbing her hands together.

Blitz stepped back, knowing her big sister would no doubt try to make her wear stupid cute outfits like she did two years ago. It was the real reason Blitz didn't want to dress up this year for Halloween, and her parents and friends didn't need to know about it.

"No, no, and no! I'm not wearing anything that's not normal clothes, and it better not be an adult costume! I'm nineteen now with three girlfriends! I can't be caught dead in one of your stupid costumes, sis!"

"Aww, come on, Blitzy. You used to love wearing my costumes. Why not one more time for Halloween?"

Spark was covered in darkness as she crept and loomed over Blitz. She wasn't giving up, and she would get her way.

"N-no...and sis, quit creeping on me!"

"Pwease? Pwetty pwease?" Spark asked as drool could be seen.

Blitz stepped back and fell on the stairs. She needed to do something before her sister got her way again, so she looked around the room and found her solution.

"Sis, like I said! I'm too old for this stuff! It's why I'm handing out candy this year when kids come knocking at the door." she rushed to the bag of candy and pointed to it.

"That's no fun!" Spark cried out, taking a handful from the bag.

"Well, it's to me! I'm an adult now! Not a child," Blitz replied.

Spark ate a piece of candy and sighed, looking upset.

"Aww, well, it's no fun, but I understand..." Blitz was shocked to see Spark looking at her so sad. "The last time I saw you, you were eighteen and became an adult. It reminds me that we never had a real childhood where all three of us could grow up and truly be sisters. I can't be there all the time. I have a multiverse to care for, and I don't know when I will see you or Braver again next time. I want to make up for lost time..."

Blitz didn't expect Spark to bring that up. It was true. When they were younger, they never had the chance to grow up together and become a family. Even now, they only have a few moments together, and the last time she saw Braver was when they had to say goodbye to each other.

"Sis...I..."

Spark placed her hands over Blitz, forcing her into a warm hug.

"It's okay. I understand, and I'm happy you're doing things you want. Still, I wish we had more time to spend together and have fun," Spark said.

Blitz hugged back, enjoying the warmth and smell of her big sister. "Same, sis. Sorry for being an asshole, but like I said, I'm an adult now, and I can't be seen as a kid anymore."

Spark pushed her back a bit. She looked down at Blitz and soon snapped her fingers in disappointment.

"Damn, I hope the sad talk would get you to dress up in an outfit for Halloween."

Blitz smacked her big sister's giant chest, making it jiggle as she was so annoyed with her.

"Damn it, Spark! Why did I think you would be sad for a minute?! You're the worst sister!"

Spark chuckled, enjoying the soft and pleasant feel of Blitz's hands smacking her chest. She wanted it to last forever, but the house's doorbell soon rang.

"Looks like the kids are coming," Spark said.

"Yeah, guess I better get ready."

Blitz heads to the door, takes out a handful of candy, and opens the door.

"Trick-or-Treat, Blitz!! Oh, hi Spark!"

Blitz and Spark blinked as they looked at the person at the door. It was Lucy, but she was dressed up as Blitz and even painted her face blue.

"Lucy?"

"Surprise!"

Blitz blinked. "Why are you here, and why are you dressed like me?!"

Lucy smiled as she posed coolly. "I'm not you!" she spun around and made a peace sign. "I'M THE RAINBOW COMET! THE TOWN'S SUPER HERO!"

Blitz could feel the secondhand embarrassment as her girlfriend, Lucy, kept posing. When she wasn't human, Blitz would transform into her anthro form and become the superhero Rainbow Comet. This was also why she was in her anthro form right now, as many would believe she was cosplaying as her superhero alter ego. Halloween was the only time she could be herself rather than human.

Lucy stopped posing and smiled. "So...yeah, I'm dressed like you, but why wouldn't I? You're a great superhero and person, and I love you."

Blitz didn't know what to say or how to feel. She was happy that her girlfriend loved her and was willing to dress up like her, but she had to say something to her.

"Lucy, I love you too, but come on! I can't believe you!" Blitz said in a disappointed tone, shaking her head.

Lucy didn't understand what she did wrong.

"Why are you mad? Aren't you happy that I dressed up as you for Halloween?"

"Why would I be happy you're dressed up as me?!"

Lucy's smile vanished. She felt sad now.

"I thought you be-"

Blitz dropped the candy back into the bag and gave Lucy a disgusted face. Lucy could even see Spark doing the same reaction but also filled with hate. Lucy became worried she had done something beyond wrong.

"What the hell, Lucy! I can't believe you would blueface me!"

"WHAT!?" Lucy shouted. She turned to Spark and could see her mouthing to her that she was going to kill her. Lucy gulped. "N-no, wait! It's not what you think! I didn't know this would be-"

Lucy tried to explain, but she could feel the heat of her girlfriend's and Spark's eyes as they stared at her with rage and disgust. Lucy knew that whatever she would say next, they wouldn't listen.

"Just get the hell out of here! I'm breaking up with you, you Equestrian racist!"

"Wait, let me-"

Before Lucy could say another word, Blitz slammed the door in her face. Lucy stood there, shocked at what happened. She could feel the tears building up.

"I-I'm not a...racist...I didn't know..."

She fell to her knees and cried. She couldn't believe Blitz had broken up with her, and she had a bad feeling that Spark would get her and make her suffer. She heard the door opening and looked, seeing Blitz and Spark laughing.

"That was your trick!"

"Eh!?"

Lucy couldn't believe it. They had tricked her! They were smiling, but Lucy didn't see it as funny.

"Why are you guys smiling!? That wasn't funny! I thought I did something beyond awful! You assholes!" Lucy cried out, standing up and pounding weakly on Blitz's head.

"Hey, hey! Come on, it's a joke! I know you aren't a racist. I was messing with you. You're my girlfriend, and I love you."

Blitz brushed her off and kissed her. Lucy couldn't stay mad and returned the kiss. Once the kiss broke, she turned and saw Spark looking sad. Lucy knew why, but because of that, she remembered something.

"Oh! Since you are here, I can give you this!"

Lucy put down her rainbow bookbag and took out a folder. She handed it to Spark, who quickly snatched it and began flipping through the pages.

"What is it, Spark?" Blitz wondered what Lucy had always given her older sister when she visited.

Spark shut the folder and, with her magic, teleported it away into hammerspace. She stepped closer to Lucy and nodded at her. Lucy nodded back with pride. The two just looked at each other like they didn't need words to tell each other.

"Uh, can one of you explain what just happened? Please?" Blitz asked, looking a bit weirded out.

Spark and Lucy faced her, smiling. Lucy answered her. "Oh, nothing! Don't worry about it!"

Blitz wanted answers, but some part of her knew better than to keep asking. She was glad Lucy was no longer angry with her.

"You forgive me, right?"

"I do, but you shouldn't have scared me like that." Lucy stood up and put the backpack back on. "Anyway, why aren't you dressed up? I thought you loved Halloween?"

"Well-"

Spark teleported behind Blitz, placing her large breast on top of Blitz's head. She squeezed her little sister but had a disappointed look. "Get this. She says she's too old to dress up and doesn't want to do it. Not cool, little sis!"

Lucy blinked.

"You don't want to dress up? Why?"

Blitz was about to speak, but Spark answered for her again.

"Because she's an old fart now!"

Blitz elbowed her sister, causing Spark to stumble back, and rubbed her side. "Stop it, you asshole! I'm not an old fart! I'm still young but no longer need to dress up like a kid!"

"Yeah, and you're a party pooper, too," Spark said. She started to dream of all of the cute outfits she wanted to dress Blitz in. "I want my old little sister back! The one that sucked on my tit as she was still a tiny slime and wanting warmth as we were being blasted by cold air as our evil crazy grandfather was testing on us." she made a motion with her breast as she made sucking noises.

"STOP THAT!!! I CAN'T BELIEVE THE MOST TRAUMATIC THING IN OUR LIVES, AND THAT IS THE THING YOU REMEMBER THE MOST FROM IT! BRAVER AND I NEEDED MAGIC AT THE TIME TO STAY ALIVE AND-"

Lucy couldn't help but laugh at her girlfriend's red-faced look, and Spark looked proud of herself.

"You two are a riot, and you're so cute, Blitz when you act like this around your big sister!"

Blitz's anger was replaced by embarrassment, and Spark was happy. She wrapped her arms around Blitz, and her boobs squished her little sister.

"See! My little sister is cute!"

Blitz blushed and didn't argue, letting her older sister hold and squish her against her body. Lucy kept laughing but stopped.

"Shame you didn't dress up as well! I swear, I'm the only one who did in this polyamorous relationship."

Blitz raised her brow. "What do you mean?"

Lucy was about to answer but didn't.

"You'll see. Sunny and Wallflower will be stopping by soon. Anyway, I need to hit more houses and then take photos of my cosplay. The Rainbow Comet fan club forums are holding a contest to see who's the best cosplay of you!" she ran toward the sidewalk, waving at them. "See you two later! Have a nice Halloween with ya big sister, Blitz!"

They waved her off, and the moment she was gone, Spark was back in the house, sitting on the couch. She patted her lap and smiled at Blitz.

"Come on, sit down."

Blitz closed the door and turned to her. "You want me to sit on your lap?"

"Yep, now come on. You can't be too old for that. Plus, I got you something."

Blitz sighed. She knew her sister would want to spend as much time with her as possible so she couldn't turn her down. She walked over and sat down on her sister's meaty lap. Blitz couldn't help but blush, loving her sister's lap's soft and squishy feel.

"There. That's nice. Being in the lap of the person who cares for you and loves you," Spark said, running her fingers through her little sister's hair.

"Yeah, I guess...it's a bit nostalgic."

Spark smiled as she heard that. "Right! It reminds me of when you two would squeeze under me, looking for warmth, or when we were separated from each other as our grandfather would do his experiments on us."

Blitz was surprised by that, and Spark could feel the tension and concern from her. She patted Blitz's head.

"Don't worry. Our grandfather can't hurt us anymore. You know that. He's long dead after-" Blitz dropped into her sister's chest, surprising her. "Blitz? Are you okay? What's wrong?"

"I just remembered. The time Braver and I did something unforgivable." Blitz tried to hold back her tears as she remembered how Braver and she killed their universe, ending all life in their world. "I know it was because we fused and lost ourselves in our overwhelming power, but... it's hard!"

"It's alright. Just let it all out. Big sis will always be here for you."

Spark held her, and Blitz hugged her big sister's giant boobs, enjoying the comfort they gave her.

"Remember what Twilah, Dashie, Twilight, Dash, and the others taught you two. About moving forward and not letting the pain and suffering consume your hearts. We know the past, and we can't change it. All we can do is live for the future, and the people who care about you are always there for you, so never forget that." Spark stroked Blitz's hair. "Never stop moving forward. Don't let your spark go out."

Blitz couldn't help but cry a bit, remembering those words. Spark was right. She must never let her pain consume her. Blitz hugged her big sister's giant tits as she tried to compose herself.

"There, there. How about I show you something to distract you? Remember, I wanted to show you something."

Blitz didn't want her sister's warmth and comfort to end, so she nodded. She could feel her sister's hand moving away from her head and grabbing her body. Blitz could feel her body being pushed off her sister's lap.

"Okay, let me go and-"

Something made Blitz remember back in the day, seeing Spark as a filly Alicorn pony, being taken away from her and Braver, and seeing Spark being transferred to another sealed cell to be tested on. Blitz grabbed her sister, crying for her not to leave her again.

"P-please...don't leave me again! Please, Spark, don't leave!"

Blitz couldn't stop the tears falling down her face. She feared if her sister moved away from her, she would disappear. She started to shake and remember how their grandfather blasted them with icy cold air to keep them from pounding on the glass.

"No, no, no! Please, don't take Spark away again! No!"

Spark didn't understand why Blitz was reacting like this. Had the past caught up to her and made her relive the painful memories again?

"Blitz..."

When Blitz heard Spark's worried voice, she could remember when Spark let her and Braver feed off of her to keep warm and eat, as eating raw magic was the only way a slime could keep itself alive.

"Big sister..."

Blitz couldn't calm herself, and Spark could feel the fear and terror radiating from her little sister. She needed to act, and as a big sister, she did. She patted her sister's head, telling her it would be okay.

"There, there. Big sister will make sure you're okay. Here, have a taste of this."

Before Blitz could speak, her big sister's magic touched her face and pulled her forward. Her mouth and lips touched something soft, smooth, and squishy. Blitz soon realized it was Spark's bare breast, as Spark used her magic to remove her shirt and bra. Usually, Blitz would be freaking out and shouting at her sister that she was a perverted siscon, but for some odd reason, Blitz felt a wave of nostalgic comfort and safety from this action. Blitz could taste Spark's breast's sweet taste and feel the warmth radiating from it. She wanted more, and soon, her teeth latched onto Spark's nipple, and she started to suck on it.

"AH!" Spark screamed with joy, drooling as it had been three years since Blitz had done this to her. Sure, Blitz and Braver were out of it, but it counted in her book. She looked down and couldn't stop smiling at the sight of her little sister sucking on her like a baby. "That's right. Drink and eat as much as you want. You'll regain your strength, and I'll ensure you're okay, so don't worry."

Blitz continued to drink from her big sister, remembering back when she and Braver would suck on Spark's body to stay alive and be fed. She felt safe, loved, and happy. It didn't take long for her to start crying, and Spark could tell it was because she was happy, not sad.

"Yeah, that's it. I'm here, and you're okay."

Blitz didn't know why her older sister was doing this, but she was glad she was. The pain and memories were washed away with love and comfort. Soon, she could feel something twitching in her underwear. Blitz's eyes widened as she realized that she was becoming aroused and getting a hard-on. She tried to cover it with her hands but felt her sister's magic stopping her.

"Now, now! Don't hide your little friend. There's no shame. I'll take care of it, so keep drinking, and let me handle this."

Blitz was a bit scared, as she wasn't sure how her sister would handle it. She released her mouth from her sister's nipple and looked at her with worry and fear. Fear that her sister will think she is a freak somehow.

"Sis..."

Spark knew why Blitz was worried. It seems if Slimes are brought into this universe, they become human but have both gender parts. This universe sees Slimes as slugs, making them hermaphrodites. It happened to Braver, who was more atone to her slime side than Blitz was. But since Blitz was revived in her anthro form, her slime side became more prominent, meaning she had both sex parts while in her anthro form now. In human form, she was an ordinary girl, though. When everyone knew what happened to Blitz, it didn't matter to anyone, and Spark would remind her little sister why.

"You are still you. Nothing has changed. Your body is still yours, and even though you are a hermaphrodite, I will still love you."

Blitz couldn't say anything as she heard those words, and before she could react, her sister's magic took off her running leggings, exposing her semi-hard cock and her pussy. Blitz cried out and covered herself with her hands, trying to hide it, but Spark stopped her again.

"Hey, don't cover yourself. Nothing is wrong with what you are, so trust me." Spark placed her forehead on Blitz's. "I will always love you no matter what."

"I-I...thanks..." Blitz said, trying not to cry.

Spark smiled and kissed her.

"It's alright, just let me handle it."

Spark forced Blitz back into breastfeeding and reached her hand down to Blitz's hardening cock. It twitched and throbbed at her touch. Blitz felt her sister's magic surround her member, and the next thing she knew, she was being jerked off in two different ways. She felt her sister's warm and soft hand. While also feeling the magical aura around her dick, feeling the strange sensation of energy flowing around her cock and making her tingle. Blitz felt pleasure and comfort as she fed and drank her big sister's magical milk. She couldn't believe she was doing this again, but it felt so natural for some reason, and she couldn't help but feel good.

"Good girl. Drink the stress away. Big sis is here, and everything is going to be okay."

Blitz couldn't help but moan a bit as her cock was stroked. It felt amazing, and she could feel herself thrusting a bit. But Spark stopped her.

"No, no, no! Let me do all the work. You focus on feeding and getting yourself relaxed. I'll take care of this."

Blitz blushed. The feeling of her sister's hand and the magic around her member were making her head spin and her body heat up. She didn't realize she was starting to pant a bit, and her mind was beginning to get hazy.

"Ahhh...this feels so good!"

Spark smiled, loving the look on her little sister's face. "That's right. Relax, let yourself go, and feel good. You're safe and sound."

Blitz placed both of her hands on Spark's large breast, groping and sucking them like crazy. She needed more, and the faster her sister pumped her dick, the harder it was for her to control herself.

"Fuck! Fuck! Fuck! Ahhhh!" Blitz cried, drooling a bit with milk around her lips. "It feels too good, sis! Ahhh! I don't think I can last much longer!"

"Then let yourself go! Big sister is here. I won't think of you any less. You are my little sister, and nothing can change that."
Blitz moaned, hearing her sister's words, and soon, she couldn't take anymore.

"I'm gonna cum, sis! I'm going to cum!"

"Then do it, Blitz! Cum for me, and show me how much you love me!"

Blitz's cock exploded, releasing its load and staining the couch. The white semen covered Spark's hand and most of her chest. The sticky substance stuck to her skin, and Blitz was panting. Her head was still a bit hazy and spinning, and her cock was still rock hard, but that didn't stop her from going back and sucking the nipple again. She wanted more.

"This is genuinely nostalgic. I remember how you always did this—going back for seconds or thirds. You were so greedy. Still are. Just look at how your cock is still rock-hard and ready for more. Well, don't worry, I'm not letting you go. Not until I'm done."

Blitz opened her eyes and blinked. The hazy and wonderful feeling she was having slowly faded away. "Huh?" soon, Blitz snapped out of it and started to feel embarrassed and ashamed of herself. "Oh no...no, no, no!" she looked at her big sister, her eyes filled with concern. "Sis, I'm sorry. I don't know what came over me."

"Huh?"

Spark watched as Blitz fell out of her lap and crawled to the corner, shaking her head.

"Oh god, what did I do!? Why did I do that!? Fuck! Fuck! I'm a perverted freak! Shit, how am I going to look Lucy, Wallflower, and Sunny in the eye after this!?"

Spark puffed her cheeks out and felt her eyebrow twitch. She could feel her little sister's self-loathing, and it was pissing her off. Spark stood up and stomped over to her.

"What are you doing?"

"Getting away from you! I can't believe I did that!"

"Stop, Blitz."

"No, leave me alone!"

Blitz rocketed to the living room entrance, but she found Spark there, waiting for her as she teleported, and Blitz smacked her face against Spark's massive airbags.

"Ugh! Ow! Why are you-"

"Listen, you idiot!" Blitz looked at her and was surprised by her angry expression. "There's nothing wrong in what we did! It's just our sisterly bonding!"

"Huh?"

Spark pats Blitz's head, smiling. "You were just nervous and freaked out a bit, that's all. It's fine, really. Nothing has changed, and I told you. I'll always love you." She pulled Blitz's head into her soft belly, hugging her. "Just relax. Everything is okay. Besides, you're in a loving herd, remember? Those three won't think of you any different."

"B-But-"

"Shush, remember what I told you years ago? After I helped encourage you to do the whole polyamory thing with them. I told you that in different universes, a herd is very common in alt-Equestria and its human counterpart. The pack leader is a male or female who cares for the herd. In doing so, the leader's mates will help their leader by showing support and affection for their leader—even sexual support. The herd helps the leader, and the leader helps the herd. A good herd must care for their pack leader and ensure they are healthy, happy, and well. It's a bond and connection only the closest can have." Spark lowered herself to Blitz's level and patted her head. "It's not unheard of a brother, sister, mother, or father to take care of the sexual needs of the leader if they are related, but a sibling is the most common. I just helped my pack leader, and you needed to relax and let the stress out. It was the best way. And besides, I'm happy to do it again. I've missed this, and you seem to enjoy it." she kissed her forehead. "The girls will understand, so you didn't cheat on them."

Blitz down and thought for a moment before looking back at Spark.

"Sis, you aren't part of my herd! So it does count as cheating!"

Spark gave her a wink. "So let me be part of your herd then, silly!"

Blitz's eyes widened as she could see her sister blushing.

"W-Wait! Are you sure!? You aren't just pulling my leg, right!? Because I'm not letting you in this polyamorous relationship if you are not serious about this, Sis! You also need to love my girlfriends, not just me!"

Spark's cheeks puffed out. "But I only love you! The others are nice, and I don't dislike them, but..." she sighed. "Fine, if that's what you want."

Blitz shook her head and crossed her arms. "No! This is not just about what I want! You have to love my girlfriends like family and not just tolerate them! Spark, this is not a joke, so if you're not serious about this, then-"

Before Blitz finished, there was a knock at the door, no doubt trick-or-treaters.

"Just a moment, coming!" Blitz yelled out and faced her sister. "We'll talk about this later!" she walked off to get her leggings and hopped to the door as she tried to put them on. "I'm sorry about the wait! Just give me a sec."

Spark could only smile as her little sister returned to her usual self. She knew her little sister was saying whatever because when Blitz heard she wanted in, her soft cock twitched with interest. But Blitz wasn't the type to cheat on her lovers. Even though Spark knew they would understand and accept it, Blitz wouldn't. She was just that kind of mare.

"Well, at least I know where to start." Spark chuckled as she teleported a bag into her hands after getting dressed. "Blitzy just needs one more push."

Once Blitz finished getting dressed, she opened the door and could see Deedee and her daughter at the door. Deedee was this universe Derpy. Blitz couldn't help but smile at the costumes. Deedee was wearing a poorly made Rainbow Comet outfit, while her daughter was wearing a poorly made outfit, but it wasn't Blitz's alter ego. No, it was Braver's superhero alter ego, Ink Comet. It's just a black recolor of Blitz's usual outfit.

"Awesome outfits! You two look amazing!"

"Thanks, Ms. Blitz! Ink Comet is my hero!" Blitz couldn't help but smile. "Trick or treat!"

Blitz gave them a thumbs-up.

"Sweet costumes, ladies! Here, have some treats!"

Deedee and her daughter smiled.

"Thank you, Blitz. Have a wonderful Halloween."

"Happy Halloween, Ms. Blitz!"

Blitz closed the door, but she stood there, feeling happy as she saw someone dressed up as her sister's superhero alter ego. She knew Braver would've loved it. Being called someone's hero...

"Even after all the lives we took back then...even after everything, we're still seen as heroes." Blitz felt tears forming and sniffled. "Braver, if you were here right now and being the more intelligent sister out of the three, why does that simultaneously make me happy and sad? Why is that?"

"I can't say I have the answers you're looking for. However, I can tell you the answer is simple, little sis."

Blitz felt Spark hugging her from behind again. Blitz needed someone to hold her, so she grabbed her sister's arms and held them.

"You kept moving forward and doing your best. The fact that you're a hero even after taking lives shows that people can move past what you did."

Blitz shook her head in disagreement as tears fell. "But the town doesn't know what the horrors I and Braver did! I didn't want Lucy, Wallflower, or Sunny to know what I did, so I couldn't tell them. They wouldn't have treated me the same if I had told them..."

Spark held her tighter. "But they did. You told them about your past, and they still love you because you aren't the same person back then. That's the difference. What you and Braver did was out of your control, and not only do your girlfriends know this, but everyone close to you two knows this!"

Blitz could see everyone, from friends to family, looking at her and smiling. They all understood what happened and never treated them as monsters or someone who needed to be hated.

"You did your best, and you saved people. You're a hero in more ways than one, Blitz."

Blitz cried.

"But that doesn't stop the fact that I must live with the guilt."

Suddenly, Blitz felt tears falling on her head. She tried to look, but Spark's massive chest blocked her view.

"I know...and you can't change that. However, the people here won't see you as the monster you see yourself as. You can't let it affect you anymore. I understand because you aren't the only one going through this."

Blitz wiped her tears. "Braver..."

Spark nodded. "Yes, her too, but I'm also talking about myself."

Blitz quickly held Spark's arms tighter. "What do you mean?"

Spark could only smile.

"It's okay. Don't worry. Just keep living and doing your best. If you ever feel lost or have something troubling you, come to me. I'll always be there for you two. Always."

Blitz started to sob as she didn't like how her sister was trying to hide her pain. But she could see her sister wasn't ready to speak about it.

"You can't say that and then act like that! You can't say you're a big sister and then not talk to me about your troubles! We're supposed to rely on each other, so don't be afraid to tell me anything."

Spark was caught off guard by this.

"I'm like Mom! I'll never abandon you or anyone who needs help! I'm loyal to my friends, family, and anyone who needs a friend! So please, Spark, talk to me!"

Spark couldn't help but chuckle. "Well, I suppose that's one reason those girls love you so much. You have such a big heart. Even if you were a bit dense at times."

Blitz blushed.

"Well, I have a big sister like you! What do you expect from me!? You are a kind and annoying but caring siscon! Of course, I'd turn out like this!"

Spark chuckled. "That's fine. I won't deny the siscon thing." Blitz pouted, but her big sister continued. "So, let's get to know each other again, Blitz. I'll open up more when I'm ready, but it's time I learn more about lovely sister!"

Spark let Blitz go and spun her around like a top. Poor Blitz kept spinning until her head spun, and she nearly threw up.

"I'm gonna barf, Spark..."

"Oh, sorry. I forgot how powerful I am! Oppies!"

Blitz version was all dizzy, and she almost passed out, but her eyes slowly focused, and her vision returned. Her eyes locked with Spark and her body. What she saw made her confused, but at the same time, she felt so hot and aroused.

"Sis..."

Blitz could see Spark wearing her clothes. The main reason She felt so turned on was how tight they looked on her. The tight shirt and the runner leggings showed off Spark's curves and large breasts. The clothes were almost ready to burst off her sister.

"I figured this Halloween, I decided to dress up as a great hero, and there's no great hero other than my little sister! That's what I wanted to show you!"

Blitz gulped as she could feel her dick getting hard. The tightness of the leggings was making it worse as it kept her dick down and in place, and the friction was making it impossible not to get a full erection.

"Uh, um, Sis...do you have any more clothes?"

Spark raised a brow.

"Oh? Why? Did something happen?"

Blitz nervously chuckled.

"Heh, um, well, it's kinda embarrassing." Blitz tried to play it cool, as she didn't want Spark to notice that she was starting to get hard. "You know what, it's not important, but-"

"Oh! Is it because of your hard-on!?"

Blitz blushed, feeling like a deer in headlights.

"Eh?"

Spark lowered herself and felt Blitz's bulge. Blitz gasped, feeling the soft hand rubbing her hard-on.

"You got hard again! I see. It's the clothes. It must be. You love seeing my thick body being trapped under these small..." she leaned in, whispering into Blitz's ear. "...tight..." she cooed in a sexual tone. "Clothes."

Blitz felt shivers going down her spine.

"So, Blitz, I have a question for you. Are you satisfied with just touching and sucking my boobs? Or do you want something more?" Spark pressed her breast against Blitz, who was panting, and her tongue was hanging. "Do you want to fuck them? Do you want to put that cock between my fat tits and fuck them?"

Blitz's brain shut off, and she couldn't respond. She was saying words, but they didn't make sense.

"Lil sis." Spark cupped Blitz's chin. "Tell me, do you want me?"

Blitz's lips were moving, but all that came out were incomprehensible words again. She could feel her cock trying its hardest to stand, but the tightness of her leggings was making it impossible.

"I can't hear you." Spark chuckled.

"Ugh, I..." Blitz's mind was broken now. The heat was blasting out from her head. She wanted to sandwich her dick between those massive and plump breasts. She wanted to feel the soft, warm skin rubbing her cock. She wanted to touch them squish around her penis and cover her penis...but her common sense side was still holding her back. She loved Spark but didn't want to see her big sister like this. She didn't want to do naughty things with her. She didn't want to fall and become like Spark and Braver in being a siscon! A little sister who wanted to bang her older sister was just wrong!

Spark blinked and waved her hand in front of her face.

"Blitz, can you hear me?"

Blitz loved her big sister so much and always admired her. She wanted to be like her but not like this. There was a line that she didn't want to cross, and she was not going to.

"Blitz? Did you have a stroke!? HEY!" Spark shook her little sister, worrying even more.

Blitz kept fighting with herself, telling herself that she wouldn't be a siscon and that she only wanted to be like Spark in helping others. She wanted to be like her big sister. Her thoughts soon exited from her mouth but merged as her mind was still broken.

"I WANT TO BE LIKE YOU, BIG SIS! I WANT TO BE A SISCON TOO!"

"Blitz-"

Spark didn't have time to finish as Blitz jumped on her, kissing her so passionately. It caught her off guard, but she didn't try and push her little sister off. Spark allowed her sister to kiss her, and while she didn't kiss back, Blitz enjoyed every second of it. Blitz lowered her leggings and freed her erect penis. Her hard-on was pressing against Spark's belly, and Spark could feel the heat coming from it.

"Oh, wow. Blitz, calm down."

Blitz couldn't respond and didn't have the mental capacity to do so. She was lost in her heat, and her thoughts were filled with only her sister. Spark quickly noticed this, and this made her glee with excitement.

"I see. I didn't expect this." She grabbed Blitz's chin. "But if you want to be like me..." her horn glowed, and Blitz soon wore Spark's outfit. "Then let's role-play..." she leaned in and whispered in Blitz's ear. "Big sister...'

"Eh?"

Blitz could feel Spark's hand caressing her cock.

"I'll be your little sister, and you'll be the big sister. And as your little sister, I've always wanted to pleasure you. Please, let me."

Blitz couldn't understand a word she said. She only knew that her little sister was offering to pleasure her, and as a big sister, she was going to accept her offer. Blitz had a perverted smile as she pushed her sister to the front door hallway and onto the floor. Blitz didn't waste any time as she raised Spark's shirt, shoving her cock between those massive and trapped breasts. Blitz shivered and moaned. Her penis was sandwiched between those huge breasts. It was the most pleasurable feeling Blitz had ever felt, and she had been inside her girlfriends' vaginas a ton of times. Lucy, Wallflower, and Sunny were nothing compared to this.

Spark moaned and giggled.

"Big Sister, your dick feels amazing."

Blitz smiled and began thrusting her hips, fucking Spark's tits.

"You're so good, little sis. Keep using your tits to pleasure me."

"Yes, Big Sister!"

Spark could see her little sister enjoying the moment. However, Blitz was lost in the pleasure. She was enjoying the sensation of the soft, warm, and plump skin. Blitz was drooling and panting like a dog.

"Oh, my little sister is the best. I should have dated you, not any of my girlfriends! My little sis is the best!"

Spark didn't have time to retort. She could feel Blitz's throbbing cock as she kept thrusting. Spark's boobs were smacking against her face as Blitz started to go harder, making her slime strength peeking out as the black stripe in her hair began to eat away the rainbow color of her hair. It was making Blitz's hair all black and slimy.

Spark realized this and had to put more power into her body, not to contest Blitz but to ensure that Blitz didn't break her body.

Blitz was so lost in the pleasure that she didn't notice her hair turning black and her eyes starting to pure white.

"Keep titty fucking me, big sis! Your dick is amazing! It's hitting my boobs in the best ways!"

Blitz didn't even notice the change and only increased the pace of her thrust. She was going to cum soon. Her balls were getting tighter, and she could feel the need to cum.

"Your boobs are amazing! I'm going to cum! I'm going to cum so much that I'm going to ruin your cute face and boobs with my seed! Take it all!"

"Please! Cum on my boobs, big sister! Make me your cum toilet! Fill me with your cum!"

"I'M CUMMING!"

Blitz's cock erupted with the most intense orgasm she's had yet. It was the hardest and thickest amount of cum she's ejaculated. She kept pumping it out, filling her big sister's cleavage and face with her cum. She pulled out and watched Spark sit up and remove the tight shirt. What Blitz saw made her want her sister even more. Spark pressed her breasts together and rubbed the cum around her boobs.

"Oh, you're cum is so warm and thick. I'm so happy. You're the best, big sister. Look at it; look how much you love me!"

Blitz watched as Spark spread her breasts apart, revealing the oozing and dripping semen.

"This is proof that you love me the most. No one will ever come between us."

Blitz nodded and got closer to Spark.

"You're right, little sis."

Spark blinked and started getting scared as she saw black slime tentacles forming from Blitz's pegsus wings. She feared the chaos part of the slime was taking over. She needed to make sure as she asked Blitz a simple question.

"What's your name?"

"It's B-B-Break-litz!"

It seemed the chaos slime wasn't fully taken over yet, as Blitz was still there. She needed to keep it like that. She bent over and wagged her fat ass, her leggings becoming see-through with her magic. Allowing Blitz to see her sister's pussy and ass.

"Please, big sister, fuck me. Show me how much you love me."

Blitz licked her lips. "I'll fuck you and show you that no one will ever love you more than me."

Blitz ripped off the leggings and was about to shove her cock into her sister's pussy when there was a knock at the door. This caused Blitz to open it without realizing the position they were both in and being almost naked. Spark cursed and quickly used a spell, masking the viewer with a false scene.

"Trick or Treat!"

Blitz and Spark could see older kids dressed up as classic monsters: vampires, werewolves, and witches.

"Oh, hey, kids!" Blitz waved.

"Can we get some candy, please?"

"Oh, um, just a minute!" Blitz rammed her cock into Spark's asshole and fucked her sister.

"Agh, ahhh, ahhhh!" Spark moaned.

"Are you okay, Miss?" the vampire asked.

"Ye-AHHHHH, Yes! Just a cold!"

Blitz handed the kids candy, which they happily accepted.

"Thank you!"

The kids walked away, leaving Blitz and Spark alone. Blitz looked down and noticed she had rammed her cock into the wrong hole.

"Damn it...not again! If Sunny were here, she would be laughing her ass off! Why does this happen to me!?"

Spark panted and moaned.

"Ahh, Blitz, please, stop! I can't focus!"

Blitz ignored her as she kept fucking her in the ass.

"You know what, fuck it! I'm enjoying this! If I have to fuck my sis in the ass, then so be it! I'll still cum inside her pussy anyway!"

Blitz continued her rough sex with Spark. She could feel her cock being squeezed by her sister's tight asshole. It was so hot and pleasurable. Blitz loved the sensation. She could hear her sister moaning. What made it hotter as the door was still open, making people who were walking by with their kids, were waving as to them, they could see Blitz and Spark waving back, acting like they weren't doing anything sexual.

"Ahh, ah, ahhh, ahhh, ahh, yes, Blitz, don't stop. Fuck my ass harder!"

"You're such a pervert, lil sis! But that's why I love you. Now, take my dick! Take it all in your ass!"

Blitz was about to cum again, but a group of kids came by and were about to ask for candy, but Blitz busted a nut inside Spark's asshole.

"I'm cumming again, Spark!"

Spark couldn't contain her moan as she felt the thick seed filling her asshole. It was too much, and some seeds started leaking out, making a mess on the floor. The kids were talking to the fake Blitz that the magic was showing. The real Blitz pulled out of her sister's asshole and forced her to face her ass to the kids. She lifted her tail and showed the kids the cum dripping asshole.

"Here you go, kids!"

The kids grabbed the candy that Blitz handed them, who then slapped Spark's ass. Making her push out more cum and causing her asshole to gape and the cum to flow out.

"Ahh, no! Stop!"

Blitz closed the door and looked at her sister, who almost passed out, but she still had the energy to keep up the magic spell. Blitz smiled as she picked up her sister's body and brought her wet pussy down on her cock, fucking her for real now.

"Oh, fuck, Blitz, your cock is so big."

"You're pussy is the best, Spark. It's squeezing my cock in all the right ways."

Blitz kept fucking her sister and was having the time of her life. Even more so when she kept answering the door and showing off her sex to the public. Spark's pussy was clamping down hard, and she was going to cum soon.

"Blitz, I'm going to cum soon. I can't hold it back."

"Cum for me, Spark. I'm about to cum too."

"Big Sister! I'm cumming! AH! AH! AHHH! I'm cumming!"

"I'M CUMMING TOO! TAKE MY SEED INSIDE YOUR WOMB!"

Blitz's balls tightened, and she came inside her sister's pussy, filling her up with her semen. Spark's stomach began to inflate. After a few seconds, Blitz pulled out, and her semen started to leak out. Spark was panting, and her magic spell was beginning to fade. Blitz grabbed Spark's cheeks and kissed her.

"I love you, Spark."

Hearing this, Spark felt so happy. She had always loved her little sister and would do anything for her. Her magic was recharged from that declaration, and Spark was ready for another round. She kissed her back.

"I love you too, Blitz."

Blitz smiled. "Let's keep going, and you're gonna love the next thing I'm going to do."

Blitz pulled out and made Spark kneel in front of her. Blitz held her cock and smacked it across Spark's face.

"Open wide, little sis."

Spark's mouth was open, and she was licking her lips, anticipating the taste of her big sister's cock.

"Give it to me, Big Sister. Let me suck on your thick and amazing cock."

Blitz inserted her cock into her sister's mouth and let her sister do the rest.

"Ah, yes, Spark. You're amazing at sucking my cock."

Blitz held onto her head and was helping her sister go down her shaft. It was so hot and slippery, and it tasted amazing. Blitz was so happy and couldn't believe she hadn't done this sooner. She could hear the doorbell ringing, but she didn't care. They could wait as Spark was doing a fantastic job.

"Suck my cock, Spark. Don't stop. It's your reward for being such a good little sister."

Spark was so happy. Her mind was so focused on the cock and the taste and smell. Nothing else mattered. Blitz could see the door opening. Spark's magic was active, so they were safe.

"Blitz, what the hell, man!? We were ringing and knocking on the door!"

Blitz turned and saw her girlfriends, Sunny and Wallflower. "Oh, hi, girls." She could see Sunny wearing a zipped-up black jacket, brown jeans, and black boots. Wallflower was wearing a long brown puffy coat that was zipped up, too. Blitz couldn't tell what clothes were underneath but could see the brown boots. At least Wallflower was keeping herself warm.

"Yeah, 'hi!'" Sunny folded her arms. "You didn't answer us! Why are you and Spark just standing there?"

"Spark is busy sucking my cock."

Wallflower and Sunny didn't hear that but heard whatever the spell made up as a response.

"Well, whatever, dude. We heard from Lucy you aren't dressing up for Halloween. Something about being too old now? That's just dumb, dude."

Blitz shrugged and didn't care. At the same time, the spell answered. Wallflower giggled as she listened to the spell.
"Well, we are getting too old, I guess. We'll all be in our twenties next year, so we should act like it."

Sunny glared at Wallflower, not believing what she was hearing, which wasn't the gulping sound of a dick getting sucked, but the sounds of them talking.

"Oh, not you too, Wallflower! Don't be a wet blanket like Blitz! Halloween is still fun, and we can't give up on it because we got older! Fuck that!"

"Sorry, Sunny, but I agree with Blitz. We should start acting our age."

Sunny grunted in frustration. "Fine, I'll trick or treat by myself then!"

Blitz finally turned to them and noticed something. She asked a question that they heard for real.

"Wait, you two aren't even dressed up!"

Sunny smirked as she and Wallflower were in their transformation form. Sunny was in her anthro unicorn form, while Wallflower was in her nymph form, making her skin light green.

"Yeah, we are!"

Blitz was slowly returning to normal as she gave her girlfriends a look.

"Sunny, transforming into your hybrid form isn't an outfit! You are just walking around in your regular clothes! And Wallflower..." Blitz sighed with disappointment. "Did Sunny force you to go along with this?"

Sunny stepped inside, pointing at Blitz in annoyance.

"No, I didn't force her!" she looked away, blushing a bit. "I just suggested it, and she agreed. No big deal."

Blitz looked over to Wallflower and asked her a question. "She begged, didn't she? I'm not mad at you, Wallflower."

Wallflower looked at Blitz, then away, and then back to her again. She didn't say anything, but the look on her face said everything. Sunny could tell she would be outnumbered in this argument, so she decided to bring up a point that would win.

"Well, Blitz, if you want to be a killjoy, then I guess no treat for you!" Sunny raised her black jacket, flashing Blitz with her big breasts. "You won't be sucking on these girls tonight, asshole! Someone's too old for Halloween!"

Blitz was speechless, not only because she was angry and frustrated but also because she was turned on again. Seeing Sunny's bare breast before her made her cock harden more, and she could hear Spark gaging on her cock. Sunny put her boobs away and gave her a dirty look.

"I'm gonna go have fun! Have a terrible night, jerk!"

Sunny was going to turn around and leave, but she sensed something. She looked for the source of whatever she was feeling. Wallflower noticed this and asked her what was wrong.

"I dunno, I think I'm sensing magic? Maybe a spell or something."

Sunny's senses were correct, as Spark's magic started weakening. The fake scene was slowly beginning to show what was really going on. Lucky for Blitz and Spark, Sunny and Wallflower looked away from them as they talked.

"Magic?" Wallflower closed her eyes and also felt what Sunny was feeling. "Oh, you are right! This is strong magic. What is it doing, though?"

Blitz was about to ask them what was wrong but was distracted by Spark, who was sucking her cock harder.

"Mmmm, I can't help myself, Blitz. We are going to be caught! You'll get in trouble, and we'll get exposed!" she said in Blitz's mind with magic. "It's turning me on! Please, fuck me more. I need it!"

"Are you sure?" Blitz asked her, and Spark nodded.

"Do it, big sis. Make me cum from your dick."

Blitz pulled out and came all over Spark's face. She then shoved Spark to the floor and started to mating press her, forcing her cock inside her big sister's pussy again. Blitz could hear her girlfriends talking, and her heart was pounding. She knew she could be caught any second, which turned her on too.

"Maybe what we are sensing is Spark's magic? She is a powerful artificial Alicorn, after all." Wallflower suggested, turning around with Sunny.

Sunny rubber her unicorn horn, thinking about that. "Hmmm, that could be."

The two girls faced Blitz and Spark but were seeing the actual scene before them. Both girls were speechless as they watched Blitz pound her big sister's pussy.

"Oh, fuck, you're the best, Spark. Your pussy is the best I've ever had!"

"Fuck me, big sis. Make my pussy yours! Cum inside me and make me pregnant!"

Sunny and Wallflower blush deep red, watching the incest sex. Both of them couldn't look away.

"I'm going to cum, Spark. Take my seed. I'll fill your womb with my cum."

"Yes, Blitz. Please, make me a mother."

Blitz came inside her big sister, and the two were panting. Sunny and Wallflower were still speechless. Blitz and Spark were shocked when they saw the two looking at them.

"Dude..." Sunny whispered and soon shouted as she pointed. "I KNEW YOU WERE SISCON TOO! BITCHING ABOUT BRAVER AND SPARK BEING SISCON, BUT HERE YOU ARE, FUCKING SPARK LIKE A FUCKING HORNY ANIMAL!" she sighed and whispered to herself. "Well, you are a pony after all..."

Wallflower couldn't say anything as she hid her face in her coat. Too shocked and embarrassed to speak. Sunny continued her rant.

"AND YOU! WHAT THE FUCK, SPARK! FUCKING BLITZ WHILE WE WERE HERE! BLITZ WAS RIGHT; YOU ARE A DAMN PERV!" Sunny walked back and forth, her hands up in the air. "Holy shit! Our girlfriend is fucking her sister right in front of us! I don't know what to think right now! Like, damn, dude!"

"Um, well," Blitz began, blushing deeply, "To be fair, you guys did walk in while we were having sex."

Sunny stopped and slowly glared at Blitz in a 'Really, Bitch?' kind of way. "You are so lucky that you have a nice cock, asshole!"

Wallflower spoke up, but her voice was a little shaky. "We-We shouldn't judge, Sunny. Maybe Equestrian allows incest stuff? This might be-" she couldn't finish as Sunny covered her mouth.

"No, Wallflower. Don't try to give Blitz any excuses. She knows what she's done." she placed her free hand over her face, trying to hide her blush. "And don't say that, or you'll ruin the image of Twilight, Dash, and the others! I don't want a picture of them all having incest sex or an incest relationship!" she shook her head as the image popped into her mind. "OH GOD, I CAN SEE SUNSET FUCKING HER DAD! EWWW! DAMN IT WALLFLOWER! I SEE AN ALT-UNIVERSE OF MYSELF AS PONY FUCKING HER DAD! FUCK!"

Wallflower lowered her face more into her coat and said, "I'm sorry..."

Blitz's common sense returned, and she realized she fucked up. She was trying to find the right words as she covered her shame, but for a third time, she felt Saprk hugging her from behind and whispering something into her ear.

"Fuck me again, Blitz. I can see you still hard, even with your girlfriends right before you." she blew air into Blitz's ear. Making her shiver and feel horny. "You can't resist me, and you love me, right? So fuck me more. Make them watch and listen as you make me moan and beg for your cock."

Something snapped in Blitz, causing her to tip her head to the side and transform her body into pure slime. Sunny and Wallflower saw this and backed away in fear.

"Blitz!?"

"What's going on?!"

"Don't worry, girls."

The two girls turned and saw Spark smiling at them. She was still covered in her sister's cum and was using her magic to hold the two down, blocking their magic as Blitz's tentacles formed again from her wings and slowly wrapped themselves around the two.

"Blitz is just being herself—her real self. You can't stop her. So please, enjoy what's about to come." Spark gave a perverted smile as she felt warm slime wrapping around her.

Sunny and Wallflower realized Blitz had become Breaker again, like all those years ago, but it was different. She wasn't going mad and destroying things; instead, she was just...

Sunny freed her mouth and shouted. "She's damn horny! Mad with horniness!"

When Sunny said that, all three girls could see multiple slime dicks forming around Breaker's body. Blitz had regained some control over herself, and she could see her girlfriends trapped by her tentacles.

"I'm so sorry, I'm-"

A creepy white, perverted smile appeared on her as she shut the door behind them.

"I'M GOING TO BREAK YOUR PUSSIES AND MAKE YOU LOVE IT!"

Hours later, Lucy was heading back to Blitz's house as she felt depressed.

"I can't believe I came last in the cosplay contest! I borrowed Blitz's clothes too! I thought for sure it would give me an edge or something!"

She cried as she walked up to the front door and knocked. No answer. She kept knocking, but no one was answering.

"Blitz?"

Lucy looked at the windows and saw a dim light inside. She heard what shouted like Sunny and Wallflower. She wondered if Blitz had fallen asleep while watching a movie or something. Lucky for her, she remembered the passcode with Spike.

"Rainbow Shards," Lucy shouted, making Spike appear before her.

"Hello, Lucy. I unlocked the door but before you enter, I must war-"

Lucy walked through Spike and opened the door. She was too depressed to listen and just wanted her girlfriends to cheer her up and comfort her.

"Blitz...Sunny...Wallflower! I need a-"

Lucy entered the living room and felt something wet and stinky under her shoe. She looked and saw the remains of the carpet, all slimy and wet. She saw the couch flipped over and the TV on the ground. The place was trashed.

"W-What..."

She could also see black slime covering the whole floor and parts of the wall. Lucy's heart began to race, and her mind started to panic. She tried to call for Blitz, as she feared what was happening. The lights were flickering, and to her horror, she could see Slime Blitz standing on the step of the fireplace. Around Blitz were Sunny and Wallflower, getting fucked by her slime dicks and tentacles. Lucy's knees gave out, and she fell on the slimy floor. She was shaking and couldn't move or speak. Her eyes were locked on Blitz, and Blitz's eyes were locked on her.

"Blitz...no....Breaker...oh god..."

"No, it's still Blitz, Lucy."

Lucy blinked as she heard Spark's voice. "Huh?"

She watched as Spark hovered from above, her ass and pussy being raped by the slime tentacles. Her breasts were also covered by the same tentacles, milking her as her mouth was being pounded. Spark couldn't speak to Lucy, as her mouth was full of cum and slime. She was talking to her through magic.

"I'm a weapon."

Lucy's heart was racing. She could feel the fear and terror rising within her.

"And I was created with the DNA of the alt-universe of Rainbow Dash and Twilight Sparkle—the prototype of Final Harmony and the Pre-production of the Harmony weapon. I was meant to be fused with Blitz and Braver, becoming Star Breaker. Breaker of stars and universes." Spark moaned as she felt a dick slime titty fucking her breasts, and the other one was pounding her ass harder. "But I'm my own self, a weapon to kill them if the needs arise."

Spark's mouth was free as she felt the white slime cum covering her. She turned and saw Blitz smiling and cumming, too, as she stood there.

"However, Blitz is still herself..." She turned back to Lucy and was going to continue but saw that Lucy was getting naked.

Lucy had trouble getting her leggings off as she fell on her butt. She looked up at Blitz, who was not trying to laugh. "BLITZ! YOU BETTER NOT BE LAUGHING, OR I WON'T LET YOU FUCK ME!"

Blitz quickly got rid of her laugh as she coughed. Lucy nodded, finally got off her leggings, and raced toward her with open arms. Ready to be fucked as well...

"Well!?" Lucy asked as she chewed candy from her bag and sat at the kitchen table inside Blitz's house.

Spark lowered the notebook and placed her hand under her chin. She thought deeply as she reviewed the story she had read. Lucy started to worry, as Spark had never taken this long to say anything.

"So..."

"I think it was..." Spark quickly opened her eyes and held the book above her head. "I LOVE IT! SURE, IT WASN'T SPOOKY OR HAD MUCH HALLOWEEN STUFF IN IT! BUT HOLY HELL, YOU OUTDID IT WITH THE SEX!"

Lucy sighed with relief. "Oh, good. I was worried you wouldn't like it. My first time I am writing a Halloween porn story on short notice! Glad you enjoy it! It is more fun than drawing lewd mangas!"

Spark flipped through the pages, happy at what was written. "I love how you tried to add the sad stuff about..." Spark became sad, and Lucy took notice.

"Well, when you read it, I wanted it to be more natural for you when you masturbate. Not like reading a cheap porn novel."

"Yeah, but..."

Lucy feared she took it too far in the story.

"Sorry. I shouldn't have gone so far as to add in the part about you and your sisters...problems. I know you two are still trying to deal with it, and I didn't mean-"

Spark raised her hand, signaling her to stop. "No, don't be. I'm happy. Sure, the whole part about our trauma was painful, but it helped make the story better."

Spark and Lucy looked to the living room and the sofa, seeing Blitz, Sunny, who was sitting next to Blitz, and Wallflower, who was resting her head on Blitz's lap, watching a spooky movie as they ate the leftover candy that Blitz couldn't giveaway to the trick-or-treaters.

"It helps me deal with my past. Sure, I should look for a better way to cope with what happened to us, but this story...it really helps me. Thanks, Lucy."

Lucy smiled, proud to hear Spark's words. "You're welcome."

Spark then looked at her, grinning. "So I noticed how the ending was starting to be more your fantasies than mine." She shoulder-hugged Lucy, making her blush. "So...did you and Blitz fucked like that yet? It seems you want Blitz to fuck you with her slimes."

Lucy went from regular blush to a deep red color.

"Well, um...you see, it was, ah, the story! I, uh, was thinking about that and, well, I just thought, ah, the story needs it, and I-"

Spark started laughing and chatting with Lucy while Sunny looked at them. She then lowered her head and rested it on Blitz's shoulder.

Sunny popped a candy corn into her mouth and slightly looked at Blitz. "What are those going on about? Lucy always drawing or writing for your sister when she comes to visit."

Blitz shrugged. "I don't care, and I don't want to know." she suddenly felt a cold shiver run down her spine. "Knowing Spark, it's something I should be worried about, but I just don't have the strength to face it right now. Plus, I want a normal Halloween night, so no drama, please."

"Right," Wallflower added. "We've had enough drama after whole saving the multiverse a few years back. Let's have a nice life with less action."

"Yup," Sunny added, snuggling closer to Blitz. "That's why I love our lives now. I've been able to spend more time with you, Blitz, Lucy, and the others." She picked up her phone as she got a text from Tempesta, their universe Tempest.

Blitz also received a text from her saying to turn to the news channel. She changed the channel and was stunned by what she saw.

"Just in, chaos at the Halloween party at the town's park! Reports are coming in that there were drunken furry sex orgies at the event behind the scenes. Police surround the park, and they are questioning the attendees."

Everyone was silent, even Lucy and Spark. Blitz started to pray, hoping this wasn't going to be another event where she needed to bail her parents and aunts out of jail again.

"Just in from the news chopper! We are getting reports of six furries wearing what seem to be ponysuits, running, and trying to escape from the police! We have audio from attendees who recorded the furries running. Here it is!"

"HOW WAS IT MY FAULT!? HOW I WAS EXPECTING TO KNOW THAT THE ADULT PARTY WAS REALLY A FUCKING FURRY ORGY PARTY!"

"I CAN'T GET ARREESTED LIKE THIS! MY HIGH CLASS LIFESTYLE WILL BE RUINED!"

"THIS ISN'T THE TIME FOR WORRYING ABOUT YOUR DAMN LIFESTYLE, SUGARCUBE! FUCKING BOOK IT, THE COPS ARE ALMOST ON US!"

"WEEEEEEEEEE!!!"

"OHDEAROHDEAROHDEAR! GIRLS WAIT FOR ME!"

Coughing could be heard. "I wish I could still transform into my hybrid form! I miss having magic for this reason..." coughing continued.

Blitz and the others watched as Dashie, carrying Twilah on her back, and the rest ran for their lives as the police force was gaining on them.

"Oh, fuck. Not again..." Blitz whispered as she lowered her head, knowing the next few days would be painful. "Happy Halloween...god damn it..."
