“There’s something weird going on between Twilight and Star.” Pinkie Pie suddenly declared. “During that picnic yesterday my Pinkie Sense was going off whenever Twilight looked at Star. Each time it was ear twitch, ear twitch, nose tickle, tummy quiver. I’m not sure what that means yet but it feels like trouble, don’t you think?”

Gummy carefully licked his left eye in response, but Pinkie was undeterred and continued to express concerns to her pet. “I can’t put my finger on it, but there’s something Twilight’s hiding. I know keeping a secret is important, but there are surprise party secrets and trying to hide bad stuff secrets. If it’s that kind of secret, then it means there’s trouble. I need to get to the bottom of this.” Pinkie slammed her fist into her left palm in determination, then noticed she hadn’t yet eaten the cupcake in her left hand and it had been smushed.

“Oh, whoopsie.” She worked to lick the frosting clean on her hand and then went to find some allies.

“What makes you think there’s something going on?” Fluttershy asked softly, pouring tea for Pinkie Pie. Pinkie had dashed over to Fluttershy’s cottage to try to get her help. As usual, the cottage was full of animals fluttering, crawling and hopping over the place. Pinkie always wondered how Fluttershy found so many creatures, or if the creatures found her.

Pinkie took a sip from her tea, then found a baby duckling had decided to rest on the saucer, so kept the teacup in her hand. “Well for starters, I asked Twilight yesterday how things were going with Starlight and she said, ‘Oh, just fine.”

“And?” Fluttershy tilted her head.

“Just fine? What kind of answer is that? It’s the sort of thing you say when you are trying to hide stuff that’s NOT fine.”

“Or maybe things are just fine.” Fluttershy shrugged. “What could she possibly want to hide from us?”

“Well...what if Starlight’s a huge slob and is making a mess in the castle and Twilight is too self conscious to bring it up? Or what if the power of having a student has gone to Twilight’s head and she’s forcing Star to do this and that for her? Or what if Starlight isn’t really reformed, has Twilight under some spell, and is secretly plotting to get revenge on us all?”

Fluttershy bit her lip and offered a forced smile, “But you don’t really think something like that is true, do you?”

“No, but that’s the point. It could be anything. There’s something going on and I intend to find out what. I just need some help with the investigation.”

“I...don’t think that’s a good idea.” Fluttershy demurred. “If there is something Twilight wants to keep secret, I’m sure she has a good reason.”

“Or a really bad one,” Pinkie insisted. “And what kind of friends are we if we don’t find out which?”

“You shouldn’t interfere with Twilight’s private life.” Fluttershy said much more firmly. “This is the kind of thing that ends with you talking to a bucket of turnips.”

Pinkie let out a long sigh. “Fiiiine. You don’t have to help, but when it turns out that Star and Twilight swapped bodies in a magic accident and have been trying to hide it, don’t come crawling to me.” Pinkie stomped off. She realized she was still holding the teacup and brought it back to the table. “Thank you for the tea.” She marched off again and closed the door behind her.

Pinkie decided to head to Rarity’s after striking out with Fluttershy. The boutique was open access in the mornings but by appointment only in the afternoons so Rarity could work on her projects. Her friends always had an open invitation, of course. Pinkie walked into the boutique and headed straight for the back room where Rarity would do her sewing.

She found Rarity hard at work on what looked like a black skirt. “Heyyy Rarity!” She called out. But Rarity didn’t seem to notice. Pinkie moved up closer and tilted her head. Rarity was incredibly focused on her work. “Hey Rarity!!!” She said again into Rarity's ear.

The second cry got her attention. “Wha….ohhh hello Pinkie. When did you get here?”

“Just a minute ago, but you were super distracted by the dress.”

“Oh yes, it’s a special order I have to get ready soon, but there should be plenty of time. What brings you by?”

Pinkie quickly outlined her thinking, giving Rarity an oddly coy smile. “Something between Twilight and Star? I suppose something like that might be possible.”

“So you’ll help me out?”

“Oh Pinkie, I don’t think we should be too nosey.” Rarity said with an overly wide grin. “If Twilight was in trouble she would ask for our help. In fact, if Twilight has something she needs to get off her chest, I expect she’ll tell us when she’s ready. We should just let her be.”

Pinkie frowned, unconvinced. “If something really really good was happening, why would she keep is a secret though?”

“Oh, lots of reasons.” Rarity giggled softly. “Really Pinkie, I’m absolutely certain nothing untoward is happening. Don’t disturb her.”

Pinkie walked away from the boutique, counting off on her fingers. “Fluttershy and Rarity won’t help, Rainbow Dash is still off in the mountains training, and Applejack is at Sweet Apple Acres and I really don’t want to have to walk all the way out there. It looks like it’s up to me.”

Just then, Pinkie noticed a head of green hair out of the corner of her eye. It was Spike, walking out of Quills and Sofas with a satchel. It was a perfect opportunity to begin investigating. She followed behind him for a block then made her move.

“Heyyyy Spike!” She jumped up and gave him a big hug from behind. It was fun seeing his reaction, especially when he would get flustered feeling her boobs pressed against him. He seemed way more flustered than usual as he looked back in shock.

“Wha...Pinkie...I uh...hi.” He blushed quite a bit and looked oddly guarded.

“Whatcha up to?” Pinkie bounced a bit.

“Oh the usual. I’m bringing some supplies back for Twilight.” He inched away, in an odd hurry to leave.

“Well, you should take a break. My place is super nearby.” She grabbed his arm and started skipping down the street, tugging him along. Once she tugged him inside she sat him on the table. “One sec!” She dashed to the back room where she had a cache of gems for future Spike parties and brought them back. “Take a load off, enjoy a few gems.”

“Uh, s-sure thing.” he said, crossing his legs and taking a bite from an emerald.

“By the way, what do you think about Twilight and Star?”

The half eaten emerald fell out of his hand. “I never...uh...what do you mean? Think about them how?”

“Well you know, what are they like when they’re together?” She leaned in closer trying to judge his expression. Spike squirmed in his seat and grew more flushed.

“T-together?” he gulped

“Exactly. You live with them both, so you must know how they act around each other. Maybe even times when they think they’re alone but you actually see them while they…”

“Ah...actually Twilight really needs these quills. Gotta go!” Spike half stood from his seat, paused, then awkwardly slid the rest of the way off and dashed out the front door with his satchel shifted to rest on his hips as he went.

Pinkie held her chin, staring at the door. “Curiouser and curiouser.” She wondered why Spike had reacted so oddly to her perfectly innocent questions. Had he seen something he wasn’t supposed to?

There was clearly no choice but to go right to the source. Thus began operation Spy on Twilight and/or Starlight Until They Spill the Beans.

Pinkie camped out in the bushes along the path that led to Twilight’s castle. She’d brought a disguise mustache and glasses along with other important spy equipment and a selection of snacks to keep her going. There was no telling when someone would come out of the castle but when they did, Pinkie could tail them and finally figure out what was going on.

After waiting just over an hour, Pinkie ran out of snacks. She knew it would be hard going without anything to sustain her, but made the commitment to stay put. Luckily, twenty minutes later she saw Twilight and Star walk out of the castle together holding hands. After about a hundred feet out of the castle, they let go of each other’s hands, but kept their shoulders touching as they chatted.

It was strange behavior for a teacher and student. Maybe it was some kind of friendship lesson? She would have to continue following them as planned and see what other information she could garner. She dipped into her bag of spy gear and pulled out a newspaper. She unfurled it to hide her face as she followed them down the street, watching carefully through the two eyeholes she’d cut in the paper.

The two of them made their way through the town square and stopped at Chez Hors D’oeuvres. That was lucky, as Pinkie was starting to get a bit hungry after almost half an hour with nothing to eat. She waited and got a seat on the far side of the restaurant and watched the two of them through her newspaper.

“Um, can I help you?” A confused looking waiter said next to Pinkie.

Pinkie held the newspaper up higher enough to continue blocking her face towards Star and Twilight. “Yes, I’d like an ice cream sundae with hot fudge, a slice of chocolate cake, and a ribeye steak medium rare.”

“Alright. Do you want your dessert at the same time as your entree or after?”

“Oh, after I’m done I’ll decide if I want to order dessert.” She replied.

“Uh, alright, I’ll send your order in.” The waiter replied. Pinkie continued her observations.

Twilight and Star had just finished ordering their own meal and had returned to staring at each other, speaking in low tones now and leaning close on the table. Pinkie couldn't hear what they were saying, but both seemed to be very focused on each other. Twilight had a soft smile on her face and was gazing into Starlight’s eyes like Star was a giant chocolate cake.

Just then, a look of surprise came over Twilight’s face which then melted into an embarrassed blush. Pinkie’s toes started to tickle, which meant something was happening low to the ground. Pinkie ducked under her table and glanced over. She could see under their tablecloth that Star’s foot was lightly stroking along Twilight’s leg.

Pinkie gasped. “Playing footsie? That’s not the sort of thing a student does to their teacher. More like….a girlfriend?” Could that be what it was? Was Twilight hiding the fact that she and Star had started dating? That might explain Spike’s odd behavior as well. A healthy boy living under the same roof as two hot girls who had the hots for each other. He might just be embarrassed about his own imagination.

At that point Pinkie’s waiter leaned down with a quizzical look. “Um, your meal is here ma’am.”

“Thank you, I’ll be back up in a moment.” She replied.

Once she was back up in her seat, she continued to watch Star and Twilight throughout their dinner, which was looking more and more like a date. They continued talking in low tones punctuated by bursts of laughter. Twilight seemed to hang on Star’s every word and once Pinkie thought about it in terms of them as a couple, she could see Twilight looked happy in a way she hadn’t ever been before.

Twilight was always happy about friendship, or magic or books, but had never really seemed interested in romance. She’d never had any long term partners, or even sex friends like Pinkie did. Even for that Canterlot guard she’d dated a few times, Twilight had never looked at him like she was looking at Star. It almost looked like Twilight was in love.

Twilight and Star shared a dessert and then headed off towards one of the nature trails nearby town. Pinkie continued to follow them through the trees that were just beginning to turn color. The further out of town they got, the more comfortable they got with their conversation. Their hands ended up reconnecting, apparently sure no one was around to see them.

As the two lovebirds got into the deepest part of the forest, Twilight tugged Star by the arm off into the trees. Pinkie carefully tiptoed to follow them. She rounded an oak tree just in time to see Star pulling Twilight into a deep kiss. That cinched it, the two of them were dating in secret.

It made a lot of sense that Twilight might want to keep that a secret. She was always bashful when it came to such feelings and she might worry what some would think about dating her pupil. But it did look like Twilight was having a good time, and that was what was really important. It seemed about as bean spilling as things were going to get.

Pinkie followed the two of them as they concluded their date, walking back to the castle and heading inside. Pinkie set her spying equipment down and nodded. “It turns out it was something really good after all.” Pinkie grinned. Twilight probably would tell everyone eventually, but now that Pinkie knew, she had to keep it a secret too. She made a Pinkie promise to herself not to spill the beans until Twilight was ready.

As she turned to leave she got a huge Pinkie Sense tingle. Her tummy quivered, her ears twitched and her butt wiggled. There was something else going on that needed looking at inside, she realized. Moving around the castle, she found one of the lowest windows. She did a small jump, then used that momentum to jump a little higher, and then higher still, grabbing hold of the window and pulling herself inside.

Her Pinkie Sense let her know to travel left down the hallway and then right, taking her to Twilight’s bedroom. The door was open just a crack and Pinkie could hear some movement inside. Carefully, she tiptoed up to peek through the door to see what her Pinkie Sense wanted her to watch.

Inside she saw Twilight and Star, but Twilight was now on her knees, completely naked with a collar around her neck. Starlight was still dressed as she’d been from the date, circling Twilight, whispering something Pinkie couldn’t hear from the doorway. Star paused in front of Twilight and pressed two fingers to Twilight’s lips. Twilight immediately began to suckle on both fingers all the way to the knuckle while her own hands drifted down to play with her pussy and breasts.

Pinkie’s eyes grew wider and wider as she watched. Not wanting to be caught, she slowly backed away from the door and tiptoed off back the way she came and hopped out the window. She stood there on the ground for a minute thinking over what she just saw.

“I just can’t believe it!” She said to herself. “Not only is Twilight dating Star, but their having kinky roleplay sex? She is sooo lucky!”

Pinkie collected her spying gear and skipped her way back to her house. Everything appeared to be fine with Twilight, but watching the two of them had gotten Pinkie a little worked up and a little private Pinkie time was in order.
