Pinkie sighed happily as she sipped her lemonade. It was summer now, and she had just finished her latest ‘spell testing session’. She smirked at the thought. They had certainly tried out some new spells - those hooks made of magic were amazing. She had no idea Twilight could do that with her horn, either. She shuddered softly, giggling as she remembered the earlier session fondly.

She thought about how these past few months had gone while Twilight showered. It had been… strange, to say the least. She had only recently gone back into heat, but both of them had continued the sessions, even without the heat. When she had revealed to Twilight just how little she really knew about BDSM, Twilight had been rather shocked. When lecturing her about the proper motions, yada yada, she had realized Pinkie learned best through ‘kinetic learning’. Meaning, they had to DO it to get it.

Pinkie wasn’t really arguing.

She had learned a lot, but she was starting to get a little bored with it all. She had been hoping today would spice things up just a tad, but it had only incorporated more physical pain - not to mention Twilight using her horn as a dildo. THAT had been peculiar (though the rough edges felt amazing inside her). Oh, and spanking. Sweet Celestia, the spanking.

But it all felt like more of the same. She took another sip of her lemonade, sighing. “Damn, it’s hot,” she said to herself, fanning off with her absentmindedly. She had been smart enough to change into a very thin tanktop and very short shorts. That still wasn’t enough to beat back the unrelenting summer sun, however. At least it was setting.

She shut her eyes and took another sip of the (thankfully cool) lemonade. She had, all in all, had a good day. Plus, she got out of her heat again. Something about being filled with magical cum soothed it all for her. She smiled softly as she remembered that feeling - being totally powerless as her friend filled her to the brim, enjoying the relaxing effects of the world being taken out of her hands so very very much. Having all the power, all the tension, on someone else was fantastic. Despite being bound and tense in her bondage, Pinkie felt totally, absolutely free.

“AHA! CAUGHT YOU RED HANDED!”

Pinkie shrieked, surprised, nearly falling out of her chair as she snapped out of the zone. The lemonade in her hand spilled, staining her already semi - transparent tanktop into a completely invisible piece of clothing. She groaned, glancing at the pony who had interrupted her daydream. “Rainbow Dash! You made me get my tank top all wet!”

Rainbow Dash crossed her arms as she flapped her wings, scowling. “Well then, just take it off - it’s not like you’re not used to being half naked in front of your friends!”

Pinkie blushed. “W-what do you mean,” she said with a grin, feeling glued to the spot in her chair. She and Twilight had agreed to keep this all a secret - had she told somepony?

“You know EXACTLY what I mean!” Pinkie gasped as Dash leaned in close, staring her right in the eyes. “I know you’ve been coming here about once a week now - or, should I say, ‘cumming’ here?”

Pinkie’s eyes darted back and forth, looking for any chance of an escape. “U-Uh, Iiiiii…”

“Well? Am I wrong? Are you and Twilight having sex?!”

“Rainbow Dash!” The mare in question stiffened up in surprise, flipping around fast. Pinkie couldn’t help but smile as Twilight walked out, a book in one hand and her reading glasses in the other. She too wore a tank top, though had opted for a skirt over a pair of shorts. Pinkie thought she looked really good, and normally would say so, but with Rainbow Dash’s accusation in the air, she decided against it.

“Twilight,” Dash said, frowning. “Maybe YOU’LL answer my question then.”

“What question,” she asked, still utterly bewildered.

“You know very well what! Are you and Pinkie fuc-”

“RAINBOW!” Pinkie couldn’t help but giggle softly as Twilight’s face flushed. This was better than when she drank all that hot sauce. “I-I- really, w-with that language,” she stuttered, blustering over words like a foal at their first public speaking class.

Rainbow rolled her eyes. “Just answer the question, Twi. Are you, or are you not?”

Twilight glanced at Pinkie, who merely shrugged. While the question had come as a bit of a surprise at first, she supposed there wasn’t much hope in hiding it from everypony. After all, they were the Elements of Harmony - one of which was Honesty. There wasn’t much hope of lying between friends.

Twilight sighed and nodded. “Well… Yeah. We are.”

“I KNEW IT!”

“Dash, keep your voice down!!”

Rainbow finally landed, folding her wings behind her back. “I totally knew it, though. You two’ve been acting so awkward around us all lately. Rarity thinks for sure that you two are dating. We’ve all got this huge bet going, but neither of you would confess to it!”

Both mares took a minute to contemplate this. “A-a bet,” Twilight stuttered out, confused.

“Yep!” Rainbow collapsed into a chair, laughing. “Looks like AJ owes me 20 bits!”

“What was your bet with Applejack,” Pinkie asked.

“I totally bet her you two were dating.”

Twilight sat as well, allowing a smirk to rise to her face. “Well then, looks like you owe Applejack the bits, not the other way around.”

“Huh?”

Pinkie giggled. “Me and Twily aren’t dating, silly! We’re just friends with benefits!” Twilight rolled her eyes at the term, but still giggled softly as she saw Rainbow Dash’s slowly comprehending face.

“You… Both of you… Friends with BENEFITS?” Dash laughed, amazed. “I never would have guessed…” Suddenly, her eyes went wide before she pouted in her seat. “Damn it! That means I lost the bet!”

Pinkie giggled, patting her on the back. “It’s okay, Dashie. Everypony loses sometimes.”

Dash sighed, rolling her eyes. “Yeah yeah. In any case, it really wasn’t hard to figure out you two were an item. I mean, the only part that REALLY got us was when we saw the marks.”

“Mar-” Twilight stopped again, looking at Pinkie’s wrists. “... Damn it.”

Pinkie glanced at her wrist too, a fresh blush rising to her cheeks. “I… didn’t realize I bruised that easily!” She giggled, shoving her hands into her lap. “Woopsies!”

“You seriously never noticed?” Dash smacked her forehead with her hand, groaning. “You’ve been walking around all month with random bruises. At first, we all passed it off as you being Pinkie Pie, but then FLUTTERSHY of all ponies brought up the fact that you only got new ones after visits to Twilight.”

Pinkie thought back. A month ago, they had started using ropes. She didn’t realize they had been tied ALL that tightly. Though, tugging against them every time Twilight thrust into her, it wasn’t too hard to believe she had left marks. “That was actually a really good observation on Fluttershy’s part,” Twilight said.

“She’s even in on the bet. Speaking of which, who’s the dom?”

Pinkie blushed further, seeing Twilight do the same. “Dashie, you can’t just ask people if they’re dom! That’s like asking people why they’re white!”

Dash rolled her eyes. “Oh, come on. It’s not like this is a huge secret between us, right? I mean, it’s obvious you two flip flop.”

Twilight tilted her head slightly. “Flip flop? You mean… change between sub and dom?”

“Totally.” Twilight shared a glance with Pinkie before both of them broke down laughing. “Oh come on! Don’t tell me I got that wrong too!”

“Pinkie’s never one up’ed me before,” Twilight said through her fit of giggles. Rainbow groaned, lying back in her chair. “In any case,” she said, clearing her throat as she stopped laughing, “we have some things to discuss then. I trust you 4 kept this between yourselves?”

Rainbow rolled her eyes. “No, Twi. We were seriously so open about the fact that you two were fucking that griffons in the Griffon Kingdom know of your little sex sessions.”

Pinkie gasped in horror. “Oh no! That means Celestia might know! Oh, I’m so sorry, Twilight, she must think you’re such a bad student!”

Twilight rolled her eyes as well. “She was being sarcastic, Pinkie.”

“Ooooh…”

Rainbow groaned, smacking her face with her palm. “Seriously, Pinks, y’gotta lighten up!”

Pinkie giggled. “I tried doing that once, but it turns out that air actually weighs something, so trying to lighten up is reeeeeeeeeeeeeeeeeeeally hard.” Rainbow squinted at the girl, trying to tell if she was joking, or if she actually meant it. Pinkie winked. “Joking.”

Rainbow couldn’t help but chuckle softly. “Alright, alright. So what happens now?”

“What do you mean, Rainbow?”

“Well… I mean…” For the first time since, well, ever, Rainbow was silent. Pinkie tilted her head. She seemed… embarrassed?

“What is it, Dashie,” she asked, smiling brightly as she worked it out. Pinkie wasn’t a dumb pony, after all. She got what Dash was really saying straight away.

“Well, I mean, Pink-” Dash stopped as, right as she looked over, Pinkie pulled her tank top over her head. Her eyes went wide as it tugged against her boobs before they came free, bouncing slightly from their weight. Her jaw dropped. “I-i- uh…”

Pinkie giggled. “Dashie, do you want to join our sessions?”

Twilight dropped her book. “Wait, what?!”

Dash cleared her throat, tearing her eyes away from Pinkie. She glanced at Twilight, her blush rampant on her face. “Well, I mean… Tsk. Yeah, alright, I wanna see what the fuss is all about. Both of you have seemed so happy lately, and with my heat coming up soon, I’ve been… thinking about it.”

Twilight looked at her, processing. “I… So… You want to…”

Dash groaned. “Yeah, I wanna learn about bondage and all that stuff!”

Pinkie giggled. “Dashie, you don’t need to be embarrassed about it!”

“Well, it is kinda embarrassing, Pinks. I don’t know how you two managed to start up these session things, but you guys just… seem so into it.”

“Well… Pinkie has had what we do as a fetish for awhile now.” Twilight cleared her throat, sitting a bit straighter as she fixed the book she had earlier dropped. “What all do you know about this, Rainbow?”

“Um… It involves ropes and shit?”

Twilight chuckled, smiling. “Well… I suppose we can teach you.”

Rainbow grinned, flaring out her wings as she rose into the air. “Aw yeah! Thanks Twi! This is going to be great.”

Twilight scratched her head. “Honestly, it’s nothing to me. We… sort of did the same thing in Canterlot a lot.”

Rainbow’s wings faltered and she fell back into her seat. “Wait, seriously?”

“Well, yeah. How do you think I learned about all this, from books?” She laughed, but stopped as she realized neither of her two friends were laughing. “... Seriously? You thought that?”

Rainbow shrugged. “What can I say? You’re an Egghead.”

Pinkie giggled. “I thought Cadance taught you!”

Twilight’s eyes went wide. “UGH!! PINKIE PIE, she was my BABYSITTER!”

Pinkie shrugged. “But she was cute, right? We saw her too, remember? She had a great rack!”

Twilight groaned as she buried her palm in her forehead. “Ugh… I’m not going to think of my brother’s wife like that right now. Just… ugh.”

Rainbow rubbed her hands together, grinning. “So, Twi, why not tell us about your virgin years at Canterlot, then? Like, your first time.”

Twilight smirked. “Oh, you don’t get to know that yet.”

Pinkie frowned. “Awww, why not?”

Twilight stood, holding her book under her arm. “Cause we haven’t gotten to anal yet, Pinkie, and I don’t think you two are ready for that.” In dead silence, Twilight walked away, shaking her rump lightly as she did. Both of her friends watched as she strode away, blushing badly.

“Is… is she always like that, Pinks?”

“Yup.”

Dash grinned. “This is gonna be great.”
