Spying on Sweetie Belle

Back at the Castle of Friendship Spike had dropped his bags on the floor and taken one of the seats by the friendship map. After the long journey from the Crystal Empire, he was exhausted. "I've missed this place."

"I imagine you have Master, and the rest of the harem too. They should be arriving on their own train with the rest of the bags soon enough. Then you'll have your whole harem of hot women to fuck Master, and won't be so lonely anymore," Cadence said. She placed down her phone that she had been using to call the Crystal Empire and ran a hand over her pregnant belly with a smile.

"You say that but I think I've got all the hot women I need here in Ponyville for now," Spike sighed, as he closed his eyes and rested his hands on his lap. "As long as Rarity is here I'll never be lonely. Isn’t she so hot that any straight woman becomes bi just from looking at her?”

Spike then realised what he just did, he opened an eye and saw the Cadence looking at him with a proud grin. "Whoops. Ah well, it'll be a nice surprise for her won't it?"

Meanwhile, the two crusaders were approaching the boutique, trailing behind the two unicorns. Rarity was following Sweetie Belle even as the younger sister struggled with the fashionista's bags. Trailing behind them, rushing from hiding spot to hiding spot were Scootaloo and Applebloom. Each was grinding their teeth as they watched their friend **** away like that.

Rarity however was quite enjoying herself and Sweetie Belle made no complaints on the matter. When they were approaching the boutique Rarity stopped. She looked around to see if anyone was watching, not noticing the crusaders hiding in the bush she turned to Sweetie Belle.

“It’s a beautiful night Sweetie Belle,” Rarity said with a grin.

The two crusaders felt the jaws fall open as Sweetie Belle stopped in her tracks, dropped her bags to the ground and pulled her skirt up. She wore no underwear so she was flashing her bare pale ass to her sister. To the horror of the crusaders, they saw a lecherous smile stretch across Rarity's face.

“I see you’ve done an excellent keeping your beautiful ass maintained dear,” Rarity said rubbing her hands across her younger sister’s rear, a single thumb rubbing against Sweetie Belle’s asshole. “Though I do hope you’re not under any delusions that your ass is superior to mine dear.”

“Mmm never Mistress,” Sweetie Belle squeaked. Back in the bushes, Scootaloo could hear Applebloom’s teeth grinding at the injustice.

“Good dear,” Rarity said before striking Sweetie Belle’s ass hard. A loud clapping sound ringing throughout Ponyville only matched the high-pitched yelp of pleasure that rang from Sweetie Belle’s lips. She dropped the bags that she had been levitating as her tongue rang out of her mouth.

“Oh dear you seem to have dropped your Mistress’ bags,” Rarity tutted, wagging her finger at the younger girl. “Make sure you pick those up dear, you’ll have to make it up to your Mistress later dear.”

“Yes of course Mistress,” Sweetie Belle gasped out between panted moans. Even as she struggled to stand she levitated the bags back up and made the final steps towards the boutique. Rarity at least had the grace to open the door for her struggling sister.

After she had closed the door behind her the two crusaders stepped out of their hiding spots. Their faces were turning green as what had just happened sunk in. They never could have believed that Rarity would ever treat her sister that way, and worse was how Sweetie Belle seemed to enjoy it.

“What the fuck is going on here?” Scootaloo asked, a hand covering her mouth in shock.

“Ah don’t rightly know. This… this can’t be happening, what has Sweetie Belle gotten herself into?” Applebloom gasped, before balling her hands into fists. “Ah’m going to get to the bottom of this.”

She stormed forwards to the boutique, Applebloom didn’t even bother to knock, she simply pushed the door open. It seemed Rarity had forgotten to lock it, no the unicorn seemed very distracted at the moment, if the screams and shouts from her bedroom were any indication.

“They’re in their room," Applebloom whispered making her way up with Scootaloo trailing behind her. They opted to be quiet, tiptoeing up to their room to investigate. Unbeknownst to them however a conversation far away from the boutique would have drastic consequences for their investigation. The two followed the moans to Rarity's bedroom and peeked inside.

To their horror, their worst suspicions were confirmed as they spied Rarity lying back on her bed, her hands pawing at her large marshmallow breasts. Her legs were spread and between them, Sweetie Belle kneeled looking up at her sister with eager, loyal eyes. They were both naked, and there was an aura of anticipation in the room so thick that you could cut it with a knife.

"What to do today Sweetie Belle? You've been a naughty girl dropping my things. You need to make up for it don't you?" Rarity chided, rubbing her hand against Sweetie Belle's cheek. It was dawning on Applebloom just how much dominance Rarity had over Sweetie Belle. Her voice was deep and sensual and held a confident joy that Applebloom couldn't help but feel envious of.

Sweetie Belle appeared to recognise it too, she leaned into her sister's touch and a rosy red spread across her pale white cheeks. “Yes, Mistress I’ll do whatever you want.”

There was a complete sincerity to Sweetie Belle’s voice, one that froze the two spies on the situation, whilst Rarity gave a good-natured chuckle. “Mmm good…Sweetie Bot.”

Sweetie Belle’s eyes glassed over before becoming focused, unnaturally focused. “Your sex bot has been activated Mistress, what is my directive?”

“Hmm…” Rarity was rubbing her breasts as she considered what to do with her sister. Compared to those beautiful white mountains, the unicorn’s hands were tiny in comparison and she could grope large chunks of tit flesh and make little dent in her tits.

Applebloom’s own breasts were the second biggest in the CMC, outshining Scootaloo’s but being outdone by Sweetie Belle. But when her hand drifted beneath her shirt there was at least a good amount of her flesh to grope.

Applebloom paused, what was she thinking? She couldn’t be into this, she liked stallions, not mares. Even if the way Rarity’s breasts rose and fell was hypnotic.

“Sweetie Belle I need you to start licking my breasts, I want you to really dig into these sensitive tits.”

“At once Mistress,” Sweetie Belle answered, her tone of voice much more stoic than usual. She leaned forwards and her soft pink tongue trailed along Rarity’s tits, tasting the ivory fur. A few light gasps could be heard from Rarity as soon as Sweetie Belle’s lips wrapped around Rarity’s nipple.

Applebloom was feeling something, feelings she didn’t quite understand. She found her hand stroking her breasts, and her mind wishing she was in Sweetie Belle’s place. Her eyes darted to Scootaloo who was in a similar position to Applebloom, though she had stripped out of her shirt completely. Applebloom could tell by the way her teeth bit her lips that her friend was struggling not to make a sound. They had to keep watching, to find out what was going on. Not that they wanted to watch.

Rarity’s hands were now stroking through her sister’s mane, pulling her deeper into her breasts. White milk sprayed out of her left tit, whilst Sweetie Belle's own mouth overflowed from the milk so some dribbled out. The spying crusaders could not help but imagine tasting that milk themselves.

"Make sure you do not waste a single drop my sexy little sex-bot. That’s a skill I’ve picked up from Pinkie and you can bet that milk tastes better than anything else.”

Sweetie Belle didn’t respond apart from the slurps of milk she drained down, Rarity herself was letting out some shrill moans of her own as she wrapped her legs around her sister. Applebloom could feel her sweat drench both her bra and her shirt, and it stuck to her like a second wet skin. It was unbearable and she couldn't resist the urge to take it off.

Not that she was getting off by watching this of course... no she was just doing this because it was so hot in the room. She didn't find this arousing not at all.

"This is disgusting. Right, Scootallo?" Even as she said the words she felt the same squirmy feeling that she often felt when she lied.

"Did-did you say something Applebloom?" She asked, her tongue rolling out of her mouth. Before Applebloom could say anything however she was interrupted with a loud shriek from Rarity.

"Oh you're doing so well my little sex machine, but now your Mistress's pussy is being left unattended. I expect you to do something about that," Rarity said, pushing Sweetie Belle off her lactating tits.

Sweetie Belle swallowing a mouthful of her sister's thick, creamy milk gave a small nod. "Of course Mistress."

She shuffled down as Rarity spread her legs into a perfect split. It only dawned on Applebloom just how perfect Rarity's legs were, sleek yet strong and so very flexible. She could easily imagine her wrapping those legs around Applebloom's neck, pulling her face into the elegant unicorn's cunt.

Applebloom's hands snaked under her shorts and was surprised by how wet her pussy was. She paused for only the briefest of moments before she spied Sweetie Belle spreading Rarity's pussy apart with her fingers and exploring it with her tongue. Scootaloo had already removed her shorts and was eagerly rubbing her pussy at the sight, not caring as her cum leaked all over Rarity's floor.

Inside Rarity's squeals and moans were like music to the young girls' ears, so heavenly and perfect. They wished they were the ones eating her pussy and making her scream. Feeling her legs pressed around their necks just as they were now pressed around Sweetie Belle's. Applebloom felt the pressure coming ahead, and she couldn't hold back an orgasm, and neither could Scootaloo. They exploded into a single pile of cum in the hallway as the two collapsed to the ground.

Inside the room however there was a pause, and both crusaders froze as they feared that they might have been heard. Neither dared to move, or utter a single word as the second passed by as if they were hours. But soon the squealing and fucking could be heard again and the Crusaders let out a sigh of relief.

They grabbed their clothes and snuck away, once down the stairs they threw on their clothes and trotted out of the boutique. Once they made some good distance they broke out into a run, trying to get away from the confusing place of Rarity's boutique.

Once they found themselves a hiding spot in an alleyway they fell to their knees. "What the hell did I just watch?"

"Ah don't rightly know. Is Rarity blackmailing Sweetie Belle to have sex with her? Ah don't get it, she's never been a pervert," Applebloom panted, before blushing red as she thought back to what had just happened. A silent agreement seemed to be shared between the two not to mention what had happened.

"Rainbow and Applejack are arriving on the eight-thirty train, we should tell them."

A/N: So the setting vote has started and I should never bet on it. I thought Canterlot would win by a landslide, people have been asking me for ages when we're getting Luna and Celestia but now Equestria Girls are leading the vote followed by the foreign kingdoms and School of Friendship. Guess you all want to see Spike bang a Siren, can't say I blame you.

This actually kind of leads me with kind of a problem, you see while I have a clear idea for an overarching arch for both of EG and the School of Friendship arc rested on the assumption that the Canterlot arc would be done. I don't have a clear idea but I believe at the end of it Spike and Rarity would be ruling Equestria openly and the foreign kingdoms would then respond to that.

But please don't feel pressured either way, vote for the setting (and the characters that come with it) however you want. Only 68 people have voted on the next setting so far so anything could happen.

Still need an editor, though I doubt there are many that can keep up with my schedule.
