Twilight’s List

Twilight was in her element writing the list, lists were her thing after all. This one was quite a bit different, however, far more important than a simple library catalogue, it was quite likely the most important list of her life. Twilight was going to remake her entire life into one of Rarity’s dreams, and in doing so become a sex **** like Cadence. For that she needed research, some things never changed. Even if the content of that research did.

“My, my, my Twilight this is quite a stash,” Cadence muttered approvingly. Looking over vast catalogues of pornographic magazines and books. Each is excellently kept in mint condition and organized in order of preference. "So which is your favourite Twilight?"

"See for yourself," Twilight teased, throwing her favourite her from her desk where she prepared a list of changes she wanted. Cadence caught her favourite and gasped with delight to see it in a hentai magazine with a picture of herself plastered on it. "I've always looked up to you, especially when I was masturbating to you."

Cadence laughed, it was so alien to hear Twilight say something dirty like that. "You dirty girl, you sure you need Spike's changes?"

"Of course. I'm only a closet slut, not an open one," Twilight protested. “And besides there’s so much more of a slut I can be.”

“That’s true. Now let’s see this list Twilight, let’s see what a magical prodigy pervert’s mind can come up with,” Cadence asked, gazing over Twilight’s shoulder.

Cadence read Twilight’s list from over her shoulder, with each sentence she smiled wider and wider. As she got a good sense of Twilight's perfectly idealized form. “A well-crafted list Twilight, though as your aunt I have you ask you about this point here."

Cadence traced the final question with her finger. “‘Is Twilight Sparkle in a slutty lesbian open relationship with fellow sex **** Sunset Shimmer?’ Twilight if I didn't know any better you were trying to **** this power to make Sunset like you," Cadence teased with a sly grin.

"Is it really that obvious?" Twilight admitted shrinking in on herself.

“Nothing to be ashamed of. But let us take our time Twilight, one by one so as to not overwhelm our master,” Cadence told her, rubbing her hands against her shoulders, feeding arousal into her sister-in-law's body. "But one day soon you and Sunset, and all your friends will slutty sex slaves for Spike and Rarity. Then you two will be a couple, serving our master as lesbian-loving slaves."

“That-that sounds wonderful,” Twilight gasped, stretching in arousal.

“And this question seems strangely worded. Why not have them now?” Cadence asked, tracing an earlier question.

“You said I won’t remember the changes Cadence but I want to feel the difference, and for the other ponies to know what I’ve done. I want them to judge me as they judge you. And I want to be proud of it, just like you,” Twilight explained, her legs rubbing together even as her voice held a childlike excitement. “And I want to put in the effort myself.”

“Well aren’t you a principled little slut? Shall we go to our Master now?”

Meanwhile, Spike was relaxing in his room, trying to put the fear of his power to one side, and was instead enjoying the new comics. Despite himself, however, his mind couldn't help but shift back to the night with Cadence, her touch, her scent, her voice and her skill all made the night omnipresent in his mind. And he couldn't help but wonder for a moment what it would be like to truly give in to the fantasy. To have all his friends at his knees slobbering over his cock.

Slowly he put down the comic and shimmed out of his trousers, reaching his hands around his cock. His thoughts turned to last night, to Rarity and her fantasy. Maybe it would be okay, for just the two of them to roleplay. If Shining Armor was okay with it, and Rarity… if Spike really was the stallion in her fantasy…

A thought that Spike found difficult to believe, but perhaps between the two of them they could roleplay. Cadence the submissive ****, and Rarity the dominant **** driver, with a riding crop in her hands, keeping the princess in line. Keeping her docile and obedient. But she would still be utterly subservient to him, their Master, their King.

“You know Spike there’s really no need to be doing that yourself when Cadence is here. Just ask her to deal with your hormones Spike,” Twilight interrupted, standing at the door with her arms crossed and a goofy grin.

In a panic, Spike threw the covers over himself, as his scale turned pink. “Twilight? Some privacy please.”

“Spike there’s nothing to be ashamed of. Your genitals aren’t small or terrible, I could see some ponies being quite entranced by them,” Twilight tried to flirt.

Tried being the keyword, as Spike found himself simply confused by his sister's actions. "Twilight what are you doing?"

“Well Spike Cadence told me about your newfound power and I found myself thinking of certain changes that I would like to see happen,” Twilight explained, unrolling her list.

“Twilight's that's insane. We need to be careful with this," Spike protested, dragging his trousers up over his dick under the sheets.

"I am being careful Spike. I’ve made a list of all the changes we should make and I’ve carefully thought about what I want and the consequences Spike,” Twilight assured him, reaching around his shoulders and pulling him towards her. Staring at him with unblinking eyes.“And believe me, I want this more than anything. This is my ticket to be just like Cadence.”

"Twilight you're freaking me out," Spike protested a quaver of fear in his voice.

“Twilight calm down. You’re scaring our master Spike,” Cadence said, standing at the door, sighing at her sister-in-law’s lack of tact and bluntness.

Ears folding in on her head Twilight backed away from Spike. “Sorry, Spike I guess I got carried away.”

“The thing is master Spike,” Cadence explained, walking up to Spike and placing her hands on his shoulders, massaging them. Soothing his agitated mind. “Twilight has always wanted to be like me, as you know Spike. But sometimes she finds it so hard to come out of her shell and trapped in her mediocre body. So when she found out about your power Spike, she saw a way to be the Twilight she’s always wanted to be. And that's your power Spike, your power to help Twilight."

Spike considered Cadence's words as her horn lit up, and he felt his doubts and fears begin to fade. Replaced with his natural wish to help her and curiosity. Sighing but admittedly curious he conceded. "Alright, Twilight. What did you have in mind?"

A/N: Didn't think that Twilight would be a very good manipulator so I had Cadence bail her out here. Suggestions and ideas are welcome as always.
