Twilight gets a visitor

As Cadence and Twilight headed down to the kitchen they heard Spike get out of bed. It seemed that he’d been awake for a while as they didn’t hear him yawning or stretching. Instead, they’d heard him making his way to the bathroom in his room, and closing the door. The awakening of their Master brought the two to the decision that they would have to split up.

“Knowing Spike he’s probably trying to drown himself now that his senses have come back,” Twilight said, eyes darting to the sound in thought. However, as she did so she noticed Candence shiver briefly. “Are you okay?”

“Yes, Twilight don’t you worry. It’s just when Spike asked if I would notice any changes when he made one. And it seems that the question is broad enough that it means I notice any change it makes." Cadence explained, before whispering. "He just whispered that his second dick would be retractable."

"Ah," Twilight said, nodding her head. "Yes, I could see why."

"I'll go to him, try to calm him down. Alone would probably be best, I've made sure he believes me but you might make it worse. You know how he sees you as a sister figure. It might worry him.” Candence explained to Twilight who nodded reluctantly.

“Alright,” Twilight admitted, head held low though Cadence soon held Twilight’s chin and pulled her to look into her eyes.

"Don't be down Twilight. You're a wonderful **** to our Master Spike and have nothing to be ashamed of." She assured her before bringing her into a long deep passionate kiss. “Now head downstairs, there are so many others that we need to recruit.”

“Right Candence I got it. You can count on me." Twilight said firmly. "I'll have another our Master another good bitch to fuck.”

Cadence giggled, the swears were unnaturally sounding coming out of Twilight’s mouth. “Then I should leave you to it.”

Humming to herself Twilight made her way down the stairs where she found her student Starlight Glimmer eating an early breakfast. When she spotted Twilight her eyes widened to the size of saucers as they flickered to her engorged chest.

"Forget anything?" Starlight asked, pointing towards Twilight's obesely enlarged bust. As she scrunched up her face within the awkward tension.

Shamelessly however Twilight simply grasped her hands around her breasts and squeezed them, displaying them to her student. "Yeah, I only just remembered to give myself the rack I've always dreamed of."

Starlight rolled her eyes, used to Twilight's slutty behaviour. "You're a great teacher Twilight, but you can't go out in Ponyville like that. Imagine what ponies would think?"

Rather than deter Twilight however this only inspired her, as she found herself molesting herself to Starlight’s disappointment. “I think they'll think me a slut and I think they'll be right."

"Ugh." Starlight groaned, massaging her temples. "Yeah well, we all heard what a slut you were last night."

"Really did you also happen to enjoy yourself?” Twilight asked but only received a dismissive eye roll.

“Well in any case Sunset left last night by the way. Perhaps because of your screaming." Starlight pointed out, this time Twilight did blush and felt ashamed. Alongside a bubble of nervousness. Surely just because Sunset knew she was a slut, she wouldn't think Twilight wasn't interested would she?

"Is that so?" Twilight asked, eyes downcast. "That's too bad."

Starlight hummed in agreement. "In any case, I’m going to be visiting Trixie today. Hope you have fun.”

With that, she teleported away with a flash of light.

"Use the door." Twilight huffed annoyed, but it was too late. Huffing to herself she enjoyed herself to the oatmeal Starlight had set out for her, Spike, and Cadence and pondered her next move. Soon though Twilight found her breakfast interrupted by a knock at the front door.

Rushing over to open it Twilight found none other than her best friend and hopeful Mistress, Rarity standing at the door. She too found her eyes flickering to Twilight’s newly enhanced body but unlike Starlight she didn’t disapprove. Instead, her reaction was a mixed one, her eyes shone with creative delight as they delved into her artistic vision of what she could do with Twilight’s new body.

But also there was an emotion she was definitely feeling. The way her teeth bit on her lips to suppress her outward moans and gasps of delight or how her legs crossed ever so slightly as a spasm of arousal sparked throughout her body. "My Twilight I see you've certainly opted for unique body proportions. Perhaps you might arrange a meeting so I can get a new outfit fitting your new measurements."

"Rarity you know that any outfit I wear becomes a stripper's uniform when I put it on and fits whatever my measurements are,” Twilight responded, causing Rarity to pout in disappointment.

"Hmpf, you think I can't get a bit risqué in my designs Twilight you don't have to worry. A true fashionista can work for any client." Rarity huffed, though Twilight sensed that there was a dirty part of Rarity's mind that enjoyed the thought of being able to dress Twilight up as a whore.

"In that case Rarity I'll have to come round soon," Twilight admitted. "Is that all?"

"Oh no darling there are two other things. Firstly I was hoping dear Spikey Wikey could show me where he found those wonderful gems and jewels. Such high quality you see."

"And the second?”

“Yes well, Sweetie Belle has found herself trying to learn a new spell. The details elude me but she found herself struggling and would greatly appreciate your help.” Rarity explained causing Twilight’s eyes to light up at the opportunity. Sweetie Belle.

“Rarity tell me how do you feel about Sweetie Belle?” Twilight asked, letting her friend into the castle.

“That’s rather an out-of-the-blue question Twilight.” Rarity said, blinking. “Well, she’s a chaotic troublemaker and has far too much energy for her own good. But that’s because she’s passionate and determined, loyal and kind as well. She’s grown into a good, beautiful young pony.”

“That’s not what I meant. I meant how do you feel about her sexually?” Twilight asked, pinning her hands on the wall over Rarity’s shoulder leaving her pinned.

“Twilight please that’s hardly appropriate.” Rarity protested but her cheeks flushed red and her voice was an octave louder than usual. “These are boundaries.”

“Boundaries?” Twilight chuckled. “I dictate the boundaries remember?”

“Twilight please-“

“We’re friends Rarity. And as the Princess of Friendship, I say we share everything together. Especially our most depraved, sexual fantasies, even if they’re a bit incestuous." Twilight explained, her eyes glowing purple as she exercised her new power. "Especially if they're incestuous."

"Of course Twilight. Forgive me I don't know what I was thinking, I know I can trust you." Rarity said calming significantly. "You won't tell Sweetie Belle?"

"No promises," Twilight said with a smirk. This caused Rarity to friendly punch Twilight in the arm.

“You’re terrible.” She whined, albeit with a smile. “Well, I confess Twilight my fantasies with Sweetie Belle are awful. I’ve always been jealous of the natural beauty that comes so easily to her. I find a certain thrill in making her a **** of a Master between us. To make it clear I am the one that who’s above her however she would be my personal ****. My not my Master’s but one I would eagerly loan to him as a favour. But she would be mine to do with as I please.”

“And what about her friends?”

Rarity paused for a moment, her fingers fidgeting against her cheek. "I don't rightly know dear. I'll have to get back to you."

"Perhaps you can think about it on your trip with Spike," Twilight suggested, as she walked out the door. "I've got to help Sweetie Belle with a spell."

A/N: Sweetie Belle won the vote. Leave suggestions for the fate of Sweetie Belle if you have any, please.

Just to clarify the bold text is Twilight using the new power she got in 'Changing Twilight' that allows her to set the boundaries between different groups. She didn't get Spike's power.
