-"Sweetie! Would you be a darling and come over here?"

Sweetie Belle just lay in her bed, reading a Daring Do book she had "borrowed" from Scootaloo. It wasn't as "REALLY AWESOME" as Scootaloo said, or at least Sweetie Belle wasn't enjoying it as much as she thought she would. After Reading the first 30 pages she felt bored and tossed the book somewhere.

-"Sweetie? Sweetie Belle?"

Rarity felt tired of calling for her sister and was confused why there was no response. She thought that maybe Sweetie couldn't hear her because she was in the basement and Sweetie was in the second floor.

Rarity noticed she was shaking a little. The activity she had prepared for her and her sister made Rarity feel antsy and excited. She stared at the immaculate table for a while, when she found herself daydreaming again she shook her head and proceeded do go upstairs. Her hooves started feeling much more stable and she started to smirk a little.

After opening the trapdoor Rarity felt dumb- "No wonder she didn't hear me...." but then snapped out of it and called for Sweetie Belle once more:

-"Sweetie Belle, would you come over here please?"

As Sweetie limply walked downstairs, Rarity observed the dull look on Sweetie's face. It didn't matter, after all, the fun was about to begin.

-"....."

Sweetie didn't even have enough strength to say anything.

-"Is everything alright, my dear?"

-"Yeah.... I'm just bored. Applebloom went to the family reunion this week and Scootaloo is sick. There's nothing interesting to do...."- She moaned

-"Oh, don't worry Sweetie. Today I guarantee you will grasp lots of excitement!"-Said Rarity wearing a big smile.

-"How come?"

-"Just follow me to the basement. I devised a fun activity for the both of us."

-"Basement?"-Sweetie looked curiously to the trapdoor behind her sister.

-"Since when do we have a basement?"

-"Now, now,that's not important, darling. Just follow me and watch your step."

Rarity started went through the trapdoor and so did her younger sister. After that, Rarity used her magic to hold a silver key and locked the trapdoor. Sweetie raised an eyebrow but didn't comment on what she just saw. Her sister seemed to hold a lot of enthusiasm regarding the activity she had planned.

Being the "drama queen" has these kinds of side effects. Everything that was bad was always "THE WORST POSSIBLE THING!" and anything that was positive was always extremely good. Sweetie Belle was already used to this kind of exagerated enthusiasm from her sister. This activity was probably some sort of boring "material selection activity" where Sweetie and Rarity were supposed to choose materials to make a dress depending on the color, pattern, texture, etc.... That's what Sweetie thought.

As the two sisters walked downstairs, Sweetie noticed the stairs, walls and ceiling had all the exact same color, a strange darkish red. The color had a weird psychological impact on Sweetie Belle, as she started to breathe slightly louder and faster than usual. Rarity perceived what happened and her smile grew even wider.

The basement had that same red color as the staircase. Sweetie saw everything execpt what she had expected: a large table with leather restraints and lots of big black boxes that looked like chests laying on the floor. The small lamp didn't illuminate very well and everything seemed somewhat creepy.

Now Sweetie had to make a giant effort not to drool. Her mind was confused and content at the same time.

-"Good. Now we can begin." -Said Rarity.

-"Well, what is the activity?"

-"You see, I want you to enjoy this as much as I do. First, lay over the table." Sweetie felt distracted, but obeyed her sister regardless. She climbed up onto the table and just lay down.

Rarity approached the table and started to restrain Sweetie.

-"What? Rarity, what are you doing?" No response. Sweetie struggled, but there was no point since Rarity is much stronger than her. Why didn't Sweetie see this coming? She already had seen the leather restrains before laying on the table. She didn't even question why she needed to be on that table.

Rarity finished restraining Sweetie's legs. The black straps held her tightly, maintaining her helpless. Sweetie's hind legs were spread, leaving her vagina VERY exposed. Due to this embarrassment, she decided to move her tail to cover her lady parts.

Rarity opened one of the chests, took something that was inside of them and then closed the chest. She then approached the table once again.

-"Sweetie Belle, do you know what this is?" -While holding a giant black dildo with her magic.

-"N-no, what is it?"

-"Well, it's a thing that ladies like us use whenever we feel bored since we don't have a boyfriend to satisfy us." Sweetie took a moment to gaze at the giant dildo. But then Rarity proceeded to do something Sweetie wasn't expecting at all, she started to insert it in her sister's vagina. Sweetie was trembling a lot due to all the nervousness. She was frantically moving her legs, trying to release from the straps, but it was no use.

-"AAAAH! It feels awful, please Rarity stop!"

After completely inserting the giant dildo inside Sweetie's vagina, Rarity removed the dildo. Sweetie felt glad that had finally stopped. Now all she-

But suddenly Rarity started to rape Sweetie Belle with the giant dildo.

-"AAAAAAAAAAAAAAAAAH! STOPRARITYPLEASESTOPITHURTSALOTITHURTS!", but Rarity didn't respond to her sister's screams. She just continued raping her sister for some minutes. After that, she removed the dildo and it was covered in blood.

-"Please Rarity..... no more........."

-"Oh, don't worry Sweetie Belle. The blood is normal the first time." And then she penetrated her sister.

Sweetie was in agony, she was screaming and crying at the same time.

-"I know for sure you will start to enjoy this as much as I do."

-"I WON'T!!!!" Said Sweetie, while Rarity continued to torture her.

After thirty minutes of rape, Rarity stopped.

-"Sweetie...... I'm so disappointed. I am trying to please you and you aren't grateful enough. And if you keep struggling I'll have to use my other tools."

-"P-please, don't!"

-"But for now, it's my turn." Rarity used her unicorn magic to penetrate herself repeatedly.

-"Oooooh.... this feels so good....."

-"HOW?" -Asked Sweetie, very disturbed. Sweetie couldn't handle it, she tried to avoid that sight by looking to the exact opposite direction.

-"SWEET FUCKING CELESTIA!"- She came. Rarity started to calm down and Sweetie was traumatized because of all this. After removing the giant dildo. She showed it to Sweetie. The dildo was covered in cum and looked really nasty.

-"Now, Sweetie Belle-

-"NOOOOO!"

-"I want you to open your mouth. This is going to be fucking awesome." The dildo was levitated to near Sweetie's face, but she shook her head and kept her mouth closed all the time.

-"Oh, so that's how it's going to be, huh. Let us do this the hard way."- She then walked away for a few seconds. Everything was so overwhelming for Sweetie Belle, the constant torture, the helplessness, her sister, and even that fucking red color was unbearable!

Rarity returned. She was holding an open mouth gag. Sweetie kept her mouth shut and turned her head away.

-“It's no use, once I put this gag your mouth will be forced wide open.” She said as she covered Sweetie’s nose whith her hoof, so that she couldn’t breath. Sweetie Belle struggled a lot, but she eventually gave up and opened her mouth to take a breath. Rarity used this opportunity to put the gag in her sister’s mouth.

The young filly started shaking her head with all the strength she had.

-“I wanted to to this the easy was, but you forced me to do it the hard way.”-She said as she used her unicorn magic to hold her sister’s head still. This made Sweetie Belle start crying nonstop. Rarity slowly put the dildo inside Sweetie’s mouth. As she did that Sweetie started to gag a little. Rarity pushed the dildo really deep down Sweetie’s throat, which made Sweetie gag even more.

After finally removing the dildo, Rarity asked “Now that wasn’t that bad was it?”

“I bet you really enjoyed it”-She winked at her sister. Sweetie started shaking her head horizontally, indicating she didn’t enjoy it at all.

-“Maybe it was a little dry. Here, I’ll put some flavor in it”-Said Rarity. She then penetrated her sister’s asshole with the dildo.

-“AAAAAAAAAAAAH!”-Sweetie screamed out in pain. Rarity just kept violating Sweetie with the dildo. Sweetie tried to use magic to stop her sister.

-“Sweetie, you really must study more “Basic Magic Movements”. I didn’t even feel a thing. If a stranger tried to rape you, you would be screwed!” Sweetie kept crying whilst her sister said that.

Rarity stopped raping her sister and started to squint at the dirty dildo.

-“Now, I think I have an idea. Why don’t you imagine this is somepony’s real cock as I puti it inside your mouth? I think I even have a blindfond somewhere, just wait a sec.” Rarity trotted away for a moment.

After searching everywhere in the basement, she approached the table once again.

-“I didn’t find the blindfold. You can just close your eyes instead. But hey, I found a camera!  How about a photograph for the family album?” Sweetie started shaking her head a lot.

-“Yes, yes. I start to feel you are actually enjoying this, Sweetie Belle.”

-“Now, lemme just”-She started adjusting the camera.

-“Aha! Now, say “cupcakes”!”-While taking a photo of Sweetie. This made Sweetie start crying.

-“This looks amazing! Oh, right. You are waiting for me, sorry about that. Lemme just put the camera somewhere so that we can proceed.”

...

-“Fuck! I’m soooooooo horny.”-Rarity started salivating and drooling.

-“Sorry Sweetie Belle, but now it’s my turn to have fun.” After hearing that, Sweetie felt relieved and started to calm down.

Rarity climbed onto the table. She removed Sweetie’s gag and threw it somewhere with her magic.

-“Now I want you to lick my vagina.”

-“WHAT?!”

-“You may proceed.” Sweetie knew it was pointless to struggle or argue any more. She decided to just obey her big sister. She nodded and started licking Rarity’s pussy.

-“Oooooooh....... yes, good filly.”-Rarity suddenly started shaking. Sweetie kept licking, when she realised she was started to like this.

-“This feels so good.” Sweetie pushed her tongue.

-“I, I..... I don’t think I can hold much longer.” confessed the elder pony.

Sweetie just continued.

-“AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH!”- Rarity finally released her orgasm, squirting into Sweetie’s mouth. Sweetie swallowed everything.

Rarity’s breathing started to slow down. After a moment, she realised her sister had stopped struggling moments ago, which made her proud.

-“Can you put the dildo again?”-Sweetie asked.

-“Why, of course I can. Where do you want it, Sweetie?”

-“Anywhere.”

Rarity started smiling. She held the dildo with magic and inserted it in Sweetie’s mouth. Sweetie started licking all around it.
