Spike sat at the dinner table, arms crossed, staring across from it with a frown like someone had told a joke at the wrong time.

It began when Twilight reminisced that one time they bought one of Pinkie Pie’s specialties and brought it home—a few weeks before magic started being drained. Then Cozy remembered when Twilight sneezed out a bunch of pastry through her nose, which they laughed at. Twilight replied with the next thing that happened that day, and they continued back and forth with every bit of detail, telling each other like they didn’t fucking remember.

And now the two were holding hooves, faces inching closer and closer without touching as they whispered with the widest grins on their faces. Their whispers sounded excited, and their smiles looked as if they hurt.

A few seconds passed, and Spike couldn’t hide a smile, but there were more important things at the moment.

Clearing his throat, he slammed his claws on the table, jumping the two out of their moment. “Girls, as much as I don’t want to get between you two, we need to talk about Cozy being the most wanted pony in Equestria.”

“It’s fine, Spike,” Twilight said. “The double is still there.”

“Yeah.” Spike nodded before pulling out a newspaper and reading it. “Twilight Sparkle, Element of Magic and Princess of Friendship, found by Applejack, a Friend of Twilight, kissing and touching filly Cozy Glow, a villain and threat to Equestria, who is as young as Applejack’s sister, which is also the believed reason for Twilight’s murder.”

Twilight deadpanned and pulled Cozy closer on her lap. “That didn’t happen.”

“But it will happen eventually if you don’t take this seriously, Twilight! Our friends always barge in like they own the damn—”

“Twilight, are you present?!” an echoed voice shouted down from somewhere. It was Rarity.

All three of them widened their eyes, and Spike immediately pushed himself away from the table. “I’ll deal with her. You two, fucking figure something out.”

As Spike ran off, Twilight groaned and tilted her head to the ceiling.

Cozy chuckled and rubbed her cheek. “Maybe we just talk to Princess Celestia and sort things out?”

“We didn’t go insane yet, so that’s a terrible idea.” Twilight kept staring at the ceiling.

“Eh.” Cozy shrugged. “We’ll figure something out then.”

Twilight sighed through her nose, hugging Cozy tight to her chest to cuddle. She kept an ear out to listen for anypony, ready to teleport at a moment’s notice. Cozy felt warm in her lap, her cute filly butt like a cloud, and Twilight thanked whoever created alicorns that her dick could be toggled off. As much as it was hot, it was also uncomfortable, and Twilight wouldn’t know if she could contain herself if she was erect.

As if Twilight could talk right now, groping Cozy’s ass. She had already rubbed her pussy a few times so she could lick her hoof and taste her sweetness. And now that she was thinking about it, Twilight wanted more. Yeah, fuck it.

Without warning, Twilight teleported them to their bedroom, where she sat down and placed a squeaking Cozy on a small tea table, her crotch now at head level.

Clutching Cozy’s hind legs, Twilight took a whiff before digging her snout into her pussy, earning her a gasp from the filly. Cozy’s wetness was pleasant on Twilight’s taste buds, and Twilight wanted nothing more than to stay here in their room so she could indulge in her filly nectar for hours.

In her work, Twilight teased Cozy by taking a few pauses and licking or kissing the inside of her pink thighs and teats. She was rewarded with a shuddering breath, music to her ears every time.

Cozy rang out quick cries as Twilight lapped up her insides, holding Twilight’s head in place as she spasmed on the table. Her sensitive folds, exposed to the predator, which was Twilight’s mouth, had nothing to defend themselves. When Twilight changed her attention to her small nub, her blush intensified, and she cried out. She tried tightening her legs around Twilight, but the mare had a firm hold on her jolting legs.

Cozy felt Twilight’s tongue exploring all inside her, extending as it wished to discover every spot inside. She was losing control of herself, her body arching and twisting. “F-fuck…”

Twilight moaned a little when Cozy came, gulping every last drop of her delicious cum. When Cozy finished, Twilight grabbed the filly by the waist and brought her into a kiss, letting Cozy taste herself, which she knew she enjoyed.

The two fought with their tongues for a bit, and Twilight pulled Cozy chest to chest in the midst. They tasted each other for a while before they pulled back for air.

With a content sigh, Cozy snuggled deep into Twilight’s fur. She didn’t want to lose this, and now, after her orgasm, her mind started fixing itself.

As Twilight rubbed her back, Cozy leaned up and kissed the underside of her chin, then nuzzled with her nose. “Spike’s right. We’re in real dangerous territory now.”

Twilight nodded, thinking about what Spike said. Then she thought about Applejack or somepony else actually walking in on them and found that exciting. As young as her sister.

She snapped her head straight, going still. “Sister…” she muttered.

Cozy stared at her for a second before frowning. “Okay, I think I know what you’re thinking of doing, but how will we convince anyone I’m your sister?”

Twilight shook her head. “Close, but I have something else in mind.”

Cozy raised a brow, and when Twilight gave her a dirty smirk, she felt her chest go tight. “What exactly?”

“You’ll see. But you’re eating me out first.”

Cozy sighed and smiled. “Sure, Sparkles.”

So Twilight took Cozy to the bed, laid her down on their soft mattress, and sat on her face.

“What. The. Fuck!”

Cozy stood before the class, trying her damndest not to glare at the ground like she wanted to murder it. Her old classmates stared at her, and the teacher for today, Spike—whose twitching lips told her he was holding every piece of laughter in—stood beside her and introduced her to the class.

“Everyone,” Spike said, wavering, “this is Snug Sparkle, Twilight’s newly adopted daughter who will be joining our class! I hope you all get to know her well and become great friends!”

“Hi, Snug!” the classes collectively shouted.

Snug. A synonym for cozy.

That name sounded so stupid hearing it from somepony else. Especially without the last name. Especially as a group shout.

Cozy wore a frilly dress that matched her old pink fur, now blue in a magic disguise. Her mane was pink and flat instead of the cute curls she worked so hard on daily. It was in her face, blocking her view. It wasn’t practical at all!

But that wasn’t close to the worst part of this disguise. Twilight had the brilliant idea of adding more accessories to her costume. Forget the dress; everything else was all she could feel on her body.

She had a purple collar around her neck with a loop in front of it. Objects settled deep in her ass and pussy, a slight hint of movement as they vibrated on the lowest setting. Of course, they were all cloaked in an invisible spell. The dress didn’t help at all. It brought attention to her rear, even though everything was invisible. She had already caught three different colts, a filly, and a griffon staring her ass down.

It was fucking bliss. Cozy would have come multiple times if it hadn’t been for the collar stopping her. Some magic bullshit. Cozy loved Twilight’s magic bullshit. Twilight had never accomplished anything like this on her before. This level of excitement and arousal was unforeseen. Shit. She wanted more.

Cozy—Snug Sparkle—didn’t pay attention in class at all. Instead, she focused on how she would get back at Twilight. She couldn’t wait. But she didn’t mind riding this out for a little while before then.
