In her manor Sunset is working in her office on the Sisterhooves Social when Rarity of all people came bursting into her office. Turns out her parents Hondo Flanks, and Cookie Crumbles had gone off on a week long vacation and left her to look after her sister Sweetie Belle. And Sweetie tried to help around the house which ended up like a sitcom. (1)

First Sweetie shrinks Rarity's favorite sweater, garnishes her drawing with rare gems Rarity needs for a big project, and straightens up the "organized chaos" of Rarity's "inspiration room". Tried to give Opalescence a bath and it ended up with a scratch up Sweetie and a wreck room. Which Rarity took it out on Sweetie by fucking her brains out to release her stress.

“This is just like a human tv sitcom, where someone tries to help but ends up causing a mess. Expect for the fact you took out your stress by fucking your sister,” Sunset said listening to Rarity story.

“Yes after I had it with Sweetie messing things up I bent her over my work table and ass fuck her till, all of my stress was gone. Sure Sweetie won’t be able to sit for awhile but she deserves it,” Rarity said.

“But she did you a favor, I told you that I don’t like gems on my outfits,” Sunset said. The gems that Sweetie used were for the dress Rarity was making for the Sisterhooves Social and why she came to see her. To explain that the dress is ruined.

“I know but it’s more of a ceremonial dress like for the Sisterhooves Social and other social events,” Rarity said.

“Well if Sweetie wants to help out. She can be your cock warmer,” Sunset said.

“Cock warmer?” Rarity asked.

“While you work you keep your cock in her. Not having sex with her but either just having your cock buried deep in her cunt or butt, or have her sucking you off. I do it all the time,” Sunset said.

“Oh that’s what you call it,” Rarity said thinking back to the times she came in to find one of Sunset’s herdmates underneath her deck, sucking or impaled on their herd leader’s cock. Which she had joined in by shoving her cock into whatever hole was open at the other end.

“Sweetie can be helping you by keeping your stress down by having your cock be kept warm inside of her,” Sunset said.

“Yes, Sweetie just grew out of her small and cute faze, now she’s a young mare who still likes doing the things she did when she was smaller,” Rarity said.

“Hasn’t she been having sex with others?” Sunset asked.

“Yes but she still likes to draw with crayons and play with her dolls,” Rarity said.

“After living in the human world, I find it so strange that we ponies don’t have a teenage stage. Just a year of sudden growth where the fillies go from small and cute to slender young mares,” Sunset said.

“Yes Sweetie was nothing but a eating machine when she hit her growth spurt. Must be nice to have it spread out by a couple of years,” Rarity said.

“Depends as the hormones do a number on teenagers,” Sunset said. “Also the teenagers grow out of playing with toys, on the most part anyways.”

“Well we all grow out of that once sex becomes a bigger part of our lives,” Rarity said. “Me and our parents gangbang Sweetie once she was done with her growth spurt to welcome her to adulthood. Now she will slowly fill out and her cock grow to its full size. I do hope that she won’t end up like Twilight where it took some time for her late growth spurts to hit her.”

“I remember that, my moms crush her bigger cock between their big fat butts to celebrate,” Sunset said. Her moms Celestia and Molestia love to smash their butts and breasts together with something between them. Which her aunts Luna and Moon joined in, using their smaller but still much larger than most other ponies.

Sunset remembers how when Rainbow was their sex toy, she had her moms and aunts give her a four way ass smash. While Cadance and herself lay on the floor with their legs crossed together so that their cocks could be buried into Rainbow’s cunt and butt. Rainbow seemed to love it as her head was squeezed between the four mountainous asses of the four older alicorns, while the two younger ones had their cocks buried into her fuck holes. The way her cunt and ass tighten as her moms and aunts grind their butts together with her head between them, told her that much. Followed by her moms and aunts turning around and squeezing their giant soft breasts around her head.

“Your moms do have big butts, and breasts. I made some designs but with how big they are, the outfits I made need be able to contain their asset,” Rarity said.

“Just make it revealing and they be happy. I’m the only one who needs clothes and not just walk around naked,” Sunset said as she remembers the dresses that actually covers her moms bodies are for cold regions. All the others are very easy for them to shove aside to reveal their breasts and cocks. Not help by the fact that they have coats and thick skins to protect them from the weather.

“Well you could firmly transform into a pony,” Rarity suggested.

“I nearly died last time remember,” Sunset said.

“Haven’t your moms came up with something that would allow them transform you fully without hurting you?” Rarity asked.

“They’re still working on it,” Sunset said.

“Also there’s another matter,” Rarity said as she brings out some design plans she brought with her in a bag. Laying them on the desk table showing they’re clothing designed modeled after the images that Sunset showed using memory magic when she told the story of Nightmare Before Christmas.

“Oh you went and made designs based on the outfits from the story,” Sunset said.

“Yes the story Nightmare Before Christmas is spreading around. Jack Skeleton and the other monsters of Halloween town is spreading since Nightmare Night been canceled for all of Equestria, thanks to Pinkie who hasn’t been the same since,” Rarity said.

“She brought it down on herself and it’s her own fault. Seeing how I told her not to ruin the holiday for my aunts. So they cancel it for everyone just because she couldn’t understand that when I said no more, it means not continue to do it just because she finds it fun. So she now has nightmares that my aunts refuse to do anything about because she’s the idiot who will keep doing something till, you press a knife to one of her fingers and tell her if she does it again she will lose it while drawing blood,” Sunset said. (2)

“Sunset!” Rarity said shocked.

“You been around her longer than me. Is she that dumb where it takes something like that to get her to understand?” Sunset asked.

“Well….,” Rarity said but has nothing. “Yes once she’s having fun like that it does take awhile to get her to stop.”

“Yup and the newspapers telling everyone in Equestria why Nightmare Night will no longer be a holiday doesn’t help her image. The only reason things aren’t as bad for her is that Halloween replaced Nightmare Night. She makes me want to just throw her into stocks and paddle her butt till it’s bleeding,” Sunset said.

“Sunset!” Rarity said.

Sunset just brought out a large folder that’s bursting with paper and drop it on her desk. Rarity saw the label on the side ‘Pinkie Files’, she was about to say something when Sunset pulls out another file. Rarity could only watch as Sunset placed 3 folders with all of them saying Pinkie on it.

“These are all the incident reports I made where Pinkie has caused a problem by being herself. Since I moved here,” Sunset said.

“Wow, I would have thought it would be bigger,” Rarity said thinking of all the stuff that Pinkie has been up to since Sunset became the governess of Ponyvile.

“Just feels like it,” Sunset stated.

Rarity’s Home -

Rarity is busy at work as she works on the Nightmare Before Christmas theme outfits. She’s busy at her work desk as she cuts and sees the cloths together, using her telekinesis to move things about. She’s in a good mood as she has lots of orders for the outfits, and her sister is hard at work in keeping her moral up.

Sweetie Belle is underneath the work desk with her nose pressed up against her older sister’s groin as she slowly sucks on her cock. Her well used cunt is still leaking all the cum Rarity had pumped into her. She’s working on her big sister’s cock being careful so that she wouldn’t cause her sister to suddenly jerk and ruin her work.

And whenever a customer comes in either her cunt, butt or mouth would be offered to them. sweetie would be spit roasted underneath the table with two large cocks in her while, the owners talk about what kind of outfit the customer wanted. And once Rarity was done, she would take her to bed. Where Sweetie would get to ram her cock into her big sister.

Sweetie moaned as she fingers herself as she sucks away at her big sister’s cock. Her own cock hardening at the thought of her fucking her big sister like she’s been doing to her. This is so much better then playing with toys or having a tea party. And Rarity told her that once their parents get back they all can have a family orgy, to show their parents what she learned from her big sister. Sweetie is so happy that her big sister is spending so much time with her, there's nothing like having sex with your sister to have some good old bonding time with each other.

Author's Note

1 - Rarity parents but for ‘Sisterhooves Social’ episode they’re just lucky to be in the background.

2 - Some episodes has Pinkie being the idiot who caused problems and does very little to solve it or at all.
