“T-trixie, I’m sorry.”

“Hm? Did you say something, Starlight Glimmer?”

Trixie was laid out on her bed, flipping through her spellbook and absentmindedly turning over the small purple remote in her hand. She smirked, unseen behind her book, at the faint sound of buzzing, and of Starlight’s labored, haggard breathing. Trixie chuckled to herself as she jotted down her notes on Twilight’s Circle of Alteration. She was confident that she could replicate it in a physical form, but applying it to a catalyst was a lot easier said than done.

“I s-said I’m sorry!” Starlight let her arms drop ever so slightly as she fidgeted, mostly through reflex, but she wished she hadn’t as soon as she moved. Trixie never looked up from her book, simply sliding her thumb up the side of the remote, dialing the vibrators taped to Starlight’s shaft and balls up two levels. “Hnnnngh! Trixie!”

“Trixie says no cumming before time, and yet you cum,” said Trixie, peering at Starlight from over her book. Starlight was kneeling a few feet from the bed, her arms raised high above her head per Trixie’s instructions. She was trembling, the vibrations causing electric arcs of pleasure to rack her entire body. “Trixie says no moving, and yet you move.”

“Yes, but—” The rest of Starlight’s sentence was lost in a long moan as Trixie raised the power of the vibrators yet again. “Hnnnnngh!”

“And Trixie says not to interrupt Trixie, and yet… Still you run your mouth.” Trixie returned the vibrators to their original settings. “That doesn’t seem like the behavior of someone who’s sorry to Trixie. That seems like a whiny, bratty little slut who needs to be punished further.”

“No! Please, Trixie, I’m sorry…” gasped Starlight. It had been three days since she and Trixie were given the task of creating a catalyst for Twilight’s intelligence spell, and Trixie had made sure it was a tortuous three days. Starlight had been teased and tormented the whole time, forbidden from touching herself in any way. Meanwhile, Trixie had been using various magical and mechanical methods of teasing Starlight, driving her mad. Trixie’s favorite was her special magical numbing cream; applying a liberal amount to any part of the body rendered it entirely unresponsive to any pain or pleasure. Trixie normally used it for performances that required her to reach into flames or thorns or other painful places, but she had found other uses for it.

Namely, riding Starlight’s cock for hours without giving the poor girl the privilege of pleasure at all, nevermind release.

“If you’re so sorry, then how come you’ve forced Trixie to do all the research and spellcasting on her own?” asked Trixie. “If you’d been helping, we may have already had a catalyst for Rainbow Dash by now.”

“Trixie, I can’t do spellwork in this condition,” complained Starlight. “I can barely think s-straight.”

“Interesting. That sounds like you’re making excuses.”

“Okay, fine. Can I at least move so I can actually see what you’re looking at?” Starlight didn’t dare move without permission, in no hurry for more punishment. Trixie chuckled to herself as she swapped out books, this one on stabilization charms.

“I don’t know, Starlight Glimmer,” said Trixie with a smirk. “Can you?”

“Yep. Sure can.”

Trixie’s smirk fell into a small frown, at which point she turned the remote up to maximum power. Starlight shrieked, her entire body tensing from the sudden pleasure. Trixie glared at Starlight for a moment before turning the vibrators back down to their lowest setting.

“Try again, without being a smartass.”

“M-may I move now?”

“Hm…” Trixie tapped her chin in faux thought before she nodded her head. “Yes, you may, Starlight.” Starlight sighed in relief, then slowly stood up and lowered her arms. She took a step forward, letting out a squeal as Trixie ramped the vibrators up yet again. The intense, almost electric shocks of pleasure made Starlight lose her footing, bringing her to her knees.

“B-but—”

“Crawl,” ordered Trixie with a sinister grin. Starlight, barely able to stand anyway, dropped to all fours and shakily made her way to Trixie. She felt about ready to burst, her cock throbbing and drooling precum onto the floor as she effectively dragged herself to Trixie, climbing up onto the bed. Once she was on the bed, Trixie shut the vibrators off for the time being. “So, Trixie has been considering how to go about binding the circle to the catalyst.”

“Stardust is a really good arcane binding agent. I think I have some at the castle,” mused Starlight. “But it needs a reactant to work. I’m not sure what we could use…”

“Hm… Brillium. Brillium should charge up the stardust enough to get the Circle going,” said Trixie. “And, if we structure the spell properly, we should be able to bind the circle to the catalyst semi-permanently, with minimal reapplication.”

“Hm… You sure you can make that happen?” asked Starlight. She took the notes from Trixie, examining her research and calculations. “Wow, this is some incredible work, Trixie. Your study on the Circle is really good.”

“Flattery won’t get you any closer to release, Starlight,” said Trixie with a chuckle. She sat up, wrapping her arms and legs around Starlight’s middle in a sort of hug. She rested her chin on Starlight’s shoulder, one hand holding a book of research notes for the two to read and the other hand gently groping Starlight’s breast. “I told you, I’m far better than anyone gives me credit for. It’s a travesty, really. Trixie truly is underappreciated in her time.”

“H-heheh. Of course,” chuckled Starlight, always amused by her friend’s over the top drama. “So. It looks like we’ve got the binding down, and the circle structure. What exactly do you need me for?”

“Well, I don’t know how well you understand Rainbow Dash,” said Trixie, flipping through her notes, landing on a list of incantations for the intelligence spell. “But I worry that she wouldn’t be able to commit the incantation to memory. And, if she accidentally says a Sombrum when she needs an Absentia…”

“It could be catastrophic, yeah. Hm… Maybe… Maybe we make a remote?” suggested Starlight. Trixie hummed curiously, swapping her book to her magical aura to free up her other hand to grab Starlight’s other sizeable breast. “Mmm… You know, it’s really hard to think when you do this to me.”

“I’m sure. Why do you think I do it?” chucked Trixie, planting a kiss on Starlight’s neck. “You’re so much more fun when you’re too horny to think straight. Too worried about when I may see fit to let you cum to think about whether or not we’re about to do something potentially stupid.”

“Speaking of stupid…” Starlight pursed her lips slightly, trying not to let herself be charmed by Trixie like she had been so many times before. “I don’t think bringing our relationship forward to Rainbow and Twilight the way we did was our smartest move.”

“Oh, what is the princess going to do? Forbid us from being together if she doesn’t approve?” asked Trixie scathingly. “We’re grown mares, Starlight. We can do whatever we want.” She brought her hands lower, gripping Starlight’s thick cock in her hands, slowly running them up and down her length. Starlight tensed slightly, her breath catching in her chest. “Are you really going to let your perfect Princess Twilight stand in between us?”

“It’s not about what she can do, Trixie, and you know that. You both mean a lot to me, and I want you to get along.”

“Hmph. As usual, the prissy princess Twilight Snarkle manages to ruin my fun,” complained Trixie. Starlight reached up with trembling hands and grabbed Trixie’s book, slamming it shut. She turned to better face her partner, trying her hardest to maintain her annoyed glare. This was easier said than done when she was so pent up she could burst and the person she was currently irritated with was the one who decided when she’d next be allowed to cum.

“Beatrix Amanda Lulamoon.” Trixie froze, unsure as to what to do next. Full names like that were never a good.

“Yes?” Trixie decided to approach the situation cautiously. She knew Starlight well enough by then to know when to push her and when to let her breathe, and this was definitely one of the latter.

“I get that you have your issues with Twilight. I get that you resent her. I get that you hate her,” said Starlight. “But Twilight is my friend. She’s one of my best friends. If it wasn’t for her, I wouldn’t have even met you. So, for that reason alone, you owe her more respect than you’ve been giving her. Please, try to get along with her.”

Trixie bit her tongue thoughtfully for a moment. Normally, Trixie was the sort to just blurt out what comes to her mind, thinking about it later, but she knew better this time. She took a moment to consider Twilight, her rival, her arch nemesis. The perfect, superior, uppity princess that had embarrassed her time and time again. Trixie wasn’t sure if hate or resentment really did her feelings for Twilight justice. There was just so much animosity between her, most of it one-sided, that Trixie struggled to say anything even remotely nice about the princess. If Trixie had her way, she’d dedicate every waking moment of her life to showing up Twilight, humiliating her like the she had been humiliated by the princess.

But, for Starlight, Trixie reasoned she could at least postpone her revenge.

“Fine. Trixie and her vast connections can secure tickets to a performance by the Royal Canterlot Orchestra,” muttered Trixie. “ I suppose, if you’re hellbent on me playing nice with that sorry excuse for a mage, Trixie can lower herself to her level for a night.”

“Trixie.” Starlight nudged Trixie, giving her a slightly more stern glare. “Respect. We just talked about it.”

“Cut me some slack. If you expect me to quit insulting Snarkle cold turkey, you’re going to be disappointed.” That earned a slight chuckle from Starlight, which made Trixie smile in turn. “What I’m saying is that Trixie would be willing to invite Twilight Snarkle and Rainbow Crash to go with us on a double date. Dinner and a show.”

“I think that’s a wonderful idea. Thank you, Trixie.” Starlight kissed Trixie on the cheek, amused to see the magician blush slightly. She grabbed Trixie by the wrist, raising them up to her chest, where Trixie began groping Starlight’s breasts almost absentmindedly. “So, back to the catalyst. A remote is going to be relatively easy once we actually create the circle. The hardest part is gonna be longevity spells and some sort of charm that makes it so only Rainbow can use it, but that’s not that hard. I know a few spells that’ll be useful. But we need the catalyst first.” Starlight paused for a moment, trying to strategize her next move. She’d need to head home to grab the stardust and other materials she might need, a trip that could take a few hours. And that was just to get materials. She still needed an actual catalyst. “Have you figured out what we’re going to use?”

“Well, you know how we need something of Snarkle’s to use?”

“Yeah. It would’ve been easier to use her hair,” noted Starlight. “A lock of her hair would have more of her residual magic than her panties. So why’d you…” Starlight stopped herself as she connected the dots. Trixie smirked when she was sure that Starlight had pieced things together, snapping her fingers. In a flash of light, Twilight’s worn, slightly-damp panties appeared in her hand.

“Well, Trixie has a few ideas in mind that I think Rainbow Dash might quite like,” said Trixie with a laugh. “Be a lamb and fetch Trixie’s sewing kit?

Author's Note

Tried to keep this short cause I wasn't sure if anyone other than me really gave a damn about the Starxie relationship. Might end up doing another story in this same canon that follows these two.
