Something quick I thought up. Enjoy!

Fortnight

Twilight couldn’t sleep.

It had been six days since Cozy Glow was sent to Tartarus for a crime that seemed unreal—a crime that no one would have expected from a filly, a crime that’s cemented her as one of the most dangerous.

An absolutely ingenious crime.

Twilight had bid Spike a goodnight and lay in her bed, staring at the ceiling for hours now.

She needed to see Cozy Glow.

Twilight rolled off the bed, lighting her magic. She knew a spell the princesses taught her, which allowed her to make a gateway to Tartarus. Aiming to the corner of her room, she shot a bolt of magic that stopped midair and turned clear. It expanded, making a fizzled doorway that showed the insides of the ancient prison.

Her heart pounded against her chest as the spell showed stability, and—after a notable pause—she made her way through, putting on a neutral look.

At once, she spotted two cages sitting next to each other. One housed the red centaur she despised for destroying her previous home, and the other contained a bright pink filly smirking at her. The expression on her face was nasty. It shouldn’t belong to anyone as young as she.

“Look what managed to drag in,” Cozy said, gripping the cage’s bars. “Missed me?”

Cozy knew what she was doing, and Twilight’s heart leaped at her teasing.

Tirek and Twilight heard two different versions of the same question.

The oblivious villain also had a sly smirk on. He probably thought Twilight was stupid enough to let him out. “It’s a pleasure to see you again, Princess,” he said with a bow.

Twilight was not here for him.

“Cozy Glow,” Twilight said, putting on her professional royal voice. “You are to come with me to prepare for your trial.”

Cozy smiled, saluting. “Sure thing, Boss! I have a specific lawyer in mind already.”

Twilight nodded—“I should hope so.”—and undid the cage’s lock. The cage wasn’t an ordinary one. It could only be opened through alicorn magic, though Twilight was sure there were other ways to escape.

Cozy walked out like a rich schoolfilly in a field of flowers. Sneaking one glance at Tirek, she stuck out her tongue, which he rolled his eyes at and huffed.

A purple hoof gestured to the portal back to Twilight’s room, and Cozy made her way through without hesitation. As she passed, her tail brushed and tickled Twilight’s leg.

Not gifting Tirek another glance, Twilight followed Cozy, the portal closing behind her.

The mood changed immediately. Cozy and Twilight stood in the center of the large bedroom, staring at each other.

Her mouth a thin line, Cozy muttered out, “Hey.”

Twilight gave a gentle smile. “Hi, Cozy.”

Cozy kicked a hoof off the ground. “I missed you.”

Twilight’s heart fluttered. “I missed you too.”

“For a second, I thought you were going to keep me in Tartarus because you were mad.”

Purple magic pulled Cozy to Twilight, and Twilight pecked her on the lips. “Don’t turn stupid on me, Cozy.”

When they last saw each other on good terms, Cozy ushered her out of her own school, insisting Twilight and her friends head to Tartarus to speak with Tirek. How devious that was. Even with hindsight, Twilight had no idea how she would have figured out what was going on before Tirek told her.

When Tirek spilled the truth, Twilight never felt a burning sensation in her chest like she ever had before. It was a wonder how she managed to keep composed and fight back. Her filly orchestrated this entire play. She was glad her friends didn’t catch her blush or arousal.

Cozy giggled. “When’s the trial?”

“Oh.” Twilight frowned. “There is no trial.”

“What? That’s… harsh.”

“More than harsh.” Twilight glared, caressing Cozy’s cheek.

Cozy knew Twilight’s intense look wasn’t directed at her, even though her eyes were. Resting her head on her purple fluffy chest, she nuzzled to calm her down. “It’s fine.”

“It’s not.” It made it much easier for Twilight to go behind their backs and free Cozy just then when Princess Celestia and Princess Luna deemed her Cozy “too dangerous.”

Cozy rose from her chest and grinned, leaning forward and kissing her. “Well, in any case, you won.”

Twilight giggled. “Yeah, but you were just brilliant, Cozy! Getting tips from Tirek to take down magic?”

Cozy lidded her eyes. “What’s a better way to come out on top against you, you Magic Abuser.”

Twilight whined. “Oh, come here, you!”

Their lips slammed together; It came with two moans that they both felt vibrate.

Fuck, how she missed this. Growing up, Twilight never knew the meaning of love. It was a foreign concept, not that she wanted to offend Cadence. Now, she was more greedy than a dragon for it.

Twilight thought nothing of it when Cozy Glow arrived at the School of Friendship. She thought Cozy was just another cute filly she had met, just like the others. But then Cozy started visiting Twilight in her office, requesting help with her friendship lessons and offering help as an assistant. Cozy often glanced down at Twilight’s scattered notes on the desk, and conversations would light up about those concepts.

Their conversations should be challenging for even adults to follow, yet Cozy would without trouble.

Time theory, quantum physics, psychology...

Even advanced magic.

Twilight never knew she found foals more attractive than she should have. She didn’t care to come to that conclusion before then. Two things held her back subconsciously: her morality and the foal’s lack of intelligence and maturity.

Cozy Glow didn’t lack intelligence or maturity. She spoke of electrolysis, giving theories of how they could use electricity as a primary power source. They had magic gadgets brewing in the works, but Cozy explained that electricity could be used for emergencies or those who don’t possess magic.

Their favorite topic was metaphysics. The conversations would keep going for hours.

After that, they started hanging out regularly, discussing friendship and other topics.

Their talks turned to flirting, turned to hugging.

It wasn’t long before their first kiss on the principal’s desk—which Cozy initiated.

Twilight didn’t feel guilty about it. She didn’t stop her. She’s glad she didn’t. Cozy made her happy, and the filly was in the right mind to stop Twilight whenever she wanted. Twilight would have stopped.

There were countless times when Cozy was hidden under Twilight’s desk when someone came to interrupt them. It was more fun than teleporting Cozy away.

Kissing led to touching, groping, and then grinding. Eventually, they got too loud, and Cozy had to visit Twilight in the castle for safety. She came over so much that she practically lived there. Life was perfect.

Then, over a week, something changed between them. A good change.

What started out with who could finish their plate faster turned into who could make the other orgasm faster. That turned into bigger dares and bets, and it only became bigger and bigger until Cozy found out the ultimate power play, one of Twilight’s big things over her—magic.

The kiss lasted only a few seconds, yet when they separated, they were breathing harder than usual. Twilight couldn’t wait. She hugged Cozy close to take her in again, pushing her tongue in and playing with Cozy’s.

During their make-out session, Twilight carried Cozy over to her—their—soft bed, throwing Cozy onto it without letting her go.

Cozy moaned and wrapped her forelegs around Twilight’s neck, pulling her close. Twilight responded by hungrily kissing deeper, pushing Cozy’s head into the mattress.

Twilight lifted a bit off of Cozy, instantly regretting it the moment she did. She wanted more. Cozy did too. She nuzzled the side of her head, leaving steps of kisses as she traveled down her neck, earning a satisfying exhale from Cozy. Despite being in Tartarus for six days, that sweet smell still lingered on her fur. Twilight’s kisses made their way to her soft chest before she raised to get a better picture. They were both short of breath.

Her eyes trailed down, and they were dripping wet below their sets of teats, slightly darker than the rest of them. Twilight knew Cozy had heat in her loins just like her, and something grew from Twilight’s crotch.

“I almost cracked when they arrested you,” Twilight said softly.

It was still fresh in her mind. When they returned to Ponyville, Twilight wanted to scoop Cozy up and shower her with kisses, admitting she lost. But, obviously, they had an act, and Twilight had to tell Cozy she was wrong and play like she was disappointed with her, even though it was quite the opposite. It pained her.

Cozy giggled softly, shifting a little under Twilight. “I almost cracked way before that.”

Cozy was a far better actor than Twilight should ever be, but if Twilight said that out loud, Cozy would reprimand her. She probably wanted to tell Twilight about her plans for the longest time, but she kept it shut for the big surprise.

Cozy’s mane was disheveled as she lay in the crumpled bed sheets under the moonlight that peered through the window, and she stared at Twilight with pure love in her lidded eyes.

She was beautiful.

Twilight wanted more. She bent down, forcing Cozy into another kiss filled with passionate moans. Her hooves trailed down Cozy’s sides, rubbing her figure before digging underneath to hold her close.

The door opened.

“Gah!” Twilight snapped her head towards the door, and there stood Spike. She stared at him nervously, and he stared back at the two of them with an indecipherable expression, his eyes going back and forth a couple of times.

Cozy blushed, looking sideways at Spike. “Hi, Spike.”

The smell of sex in the room became quickly apparent, and the two of them flushed.

Spike frowned. “I heard a noise. Two weeks. You couldn’t wait two weeks, Twilight? You said two weeks! A fortnight!”

Twilight nervously chuckled. Cozy looked away and hid her face, still hugging Twilight’s neck.

“I know!” Twilight whined. “But I couldn’t!”

Spike crossed his arms, looking at Twilight. “Well, anyway. Somepony could have gotten hurt. Cozy needs to be punished for that. And I don’t mean spankings; you both enjoy those.”

Cozy peaked out from under Twilight, resting her hooves on Twilight’s chest. “Sorry.” She liked him too, though in a more physically attractive way. His claws and feet specifically, though she admitted he had a cute face and butt as well.

Spike waved a claw. “It’s fine. We’ll talk more in the morning. You two have fun!”

He left and closed the door behind him. Twilight sighed.

Cozy reached up with a hoof and rubbed her cheek, her eyes pupils sparking and expanding.

Twilight wouldn’t fall for it. “You lost. So you were getting a punishment anyway.”

Cozy put on a pout and dropped her hoof.

Twilight giggled. “Not tonight. I’m still topping, though.” She bent down and kissed her. Cozy wrapped her legs around Twilight’s neck again and hugged her with her hind legs.

Something big and thick appeared in between them.

Alicorns didn’t only gain the traits of every pony race.

Twilight reached down and started rubbing Cozy’s teats before reaching down and rubbing her clit. She grabbed Cozy’s hooves with her magic, pinning them above her head. If Cozy had won, Twilight wouldn’t have been able to do such a thing.

As Twilight continued to rub, Cozy gasped. “T-Twilight.”

Twilight nuzzled her cheek with her own. “What is it?” she asked, her tone playful.

“Please! It’s been so long.”

Twilight agreed. “Use your words, Cozy.”

Cozy squirmed. “F-fuck me, Twilight! Fuck your filly!”

Answering Cozy’s call, Twilight lifted Cozy’s hips and entered her pussy.

Cozy’s moans bounced around the room. Twilight kissed her to quiet her, but more importantly, to feel the buzzing of Cozy’s incoherent words through her lips. It sent shocks down her spine.

Cozy was as tight as she remembered, but they were way past the careful stages of their relationship. Twilight knew full well how lenient Cozy was.

Twilight pushed deeper into Cozy’s hot cave, her pussy fluids from their make-out session providing more than enough lubrication. As she pushed further inside, it became more awkward to kiss Cozy due to the size difference. They’ve always managed despite that.

Eventually, Twilight stopped in Cozy, a mere pause. She reeled back a few before slamming right back in, conquering the last inch of her insides and hitting the back of her walls.

Cozy mewled in their kiss.

Breaking away from Cozy, Twilight took a deep breath and didn’t let Cozy catch hers before speeding up.

Their thighs clapped together as Twilight fucked Cozy, her balls smacking her butt. She was so tight and warm inside. Twilight had been feeling colder lately, so thank the heavens Cozy was on their bed. Oh, how she missed this!

Cozy couldn’t even get a word out. For the past six days, she felt so empty, but now, Twilight’s dick kept forcing breaths out of her like a pump as she filled her insides. She bounced up and down on the bed even as Twilight held her still with her hooves and magic. It wasn’t long before she started to feel pressure rise in her crotch.

Cozy came first, arching her back and gripping Twilight’s cock with her tight pussy. Twilight paused for her. She yelled to the ceiling, forgetting where she was for a moment.

Twilight continued after a short wait, bringing a whimper out of Cozy, and it only took around ten more seconds before she slammed her hips deep, feeling her cock pulse and emptying her balls inside of her adorable filly. With heavy huffs, she pulled out of Cozy, and her cum dripped out of her filly folds.

Cozy was moments away from catching her breath and saying something before Twilight flipped her over, cutting off anything she had to say. She rested on her belly for a second before she felt Twilight against her anus. Their safeword was “cranberry.”

Cozy never needed to say that word.

Twilight pushed in, forcing a groan out of Cozy. Only a few heartbeats passed before she was back in her rhythm, anally fucking her tight ass.

Cozy gasped as she kicked the bedsheets and tried to grab them with her forehooves. She couldn’t grasp the sheets with her hind hooves, so she curled them in the air instead.

Twilight held her down. She fucked her relentlessly, breathing over her like some savage canine. She brought her hips up as much as she could before slamming them down, satisfying claps raining over and over as she was brought over to the edge.

Cozy cried out a few times before she came on the bed sheets, and Twilight wasn’t far behind her as she felt her ass tense through her orgasm. Her head flared as thick ropes of cum shot all the way into the innards of her cute filly butt.

They kept still as their breathing dominated the room. Twilight rested on Cozy to catch her breath, still inside her, but Cozy never found her weight hurtful or uncomfortable.

After a moment, Twilight blew out a blissful sigh and rolled off of Cozy to lie down, her cock leaving Cozy’s ass with a pop. Using magic, she brought Cozy to lie on her chest, which the filly appreciated.

“I love you,” Cozy murmured, her head rising and falling with Twilight’s breathing.

“I love you too.” Twilight kissed her mane. “Spike’s been missing you too. I’d help him, but it still feels weird.”

“That’s fine. I don’t mind helping him out.” There was a notable pause with her. “I’m a criminal now. How does that work?”

Twilight sighed. “Well, I’ll be putting in a double in Tartarus. If by the off-chance anypony asks why ‘I dragged you out for a day,’ I already have a story made up for it.”

Cozy chuckled, rolling her head so she could look at Twilight. “That’s my Sparkle, always the planner.”

Twilight giggled and hugged her close so Cozy’s head dipped under her chin, rubbing her back.

“How are you going to maintain magic in Tartarus, though?”

“Well, it’s tricky to explain, but it’s you, so I’m not worried.”

So Twilight explained how she was going to maintain magic in Tartarus. Yup, she did, and with a totally legit reason too.
