Twilight adjusted her skirt for what was the fifth time that minute. It’s not that it didn’t fit, per se, it’s that its current fit wasn’t needed for this current situation; too long, as she had returned from the dress rehearsal for the school play not long ago. Of course, its previous fit had caused no small amount of embarrassment earlier in the morning, before breakfast and the dress rehearsal, when she had mistaken Celestia’s invitation to her chambers and the clothes set out as Celestia’s attempt to seduce her exactly how her dream had.

Now, however, Celestia had plans to seduce her in, well, Twilight didn’t completely know, and that thrilled her immensely. They had already laid the ground rules; nothing extreme, nothing humiliating or too demeaning, and everypony keeps all their features intact.

Twilight took a deep breath, and knocked once more on Celestia’s chamber doors. Her knock stuttered at first, but she followed with two solid blows to the wood, and was rewarded with a slight creek and a golden glow on the inside handle. “Headmistress? You wished to see me?”

“Indeed, Twilight Sparkle, enter. We have much to discuss about your... behavior, as of late,” Celestia said with a hard edge, sending tingles down Twilight’s spine.

Twilight obeyed and then heard a tell-tale metallic click behind her as the door latched shut. She forced herself to keep looking ahead, though, and was rewarded with a sight she didn’t expect to see again. Unlike earlier that morning, when Celestia just wore a tan suit jacket, she now also sported a short black skirt that showed off her magnificent white flanks and some black fishnet stockings held up by a garter under the skirt. Twilight bowed her head and said, “Headmistress.”

“Sparkle!” Celestia barked.

Twilight snapped her head up and her ears shot forward. “Yes, ma’am!”

Celestia stepped forward and glared down her muzzle to Twilight. “It has come to my attention that you’ve been, shall we say, attempting to bribe your teachers with sexual favors.”

Twilight visibly gulped. “Yes, Headmistress,” she muttered.

“Needless to say, we will not tolerate such salacious behavior,” Celestia continued as she paced in front of Twilight, offering her student a glorious view of her rump. “Eyes forward!” she snapped when she caught Twilight following her movements. Twilight, as usual, obeyed immediately. “So it seems we must find a punishment suitable for such an,” she stepped forward and whispered directly into Twilight’s ear, “incorrigible, pretty little filly.” Celestia finished with a nibble to the tip of Twilight’s ear and elicited a high-pitched yelp from her. Celestia giggled softly and pulled back, flashing Twilight a genuine smile before she replaced it with the hard, stern look of the Headmistress she was playing.

Celestia turned around and strode to her desk, cleared of its usual papers and books, instead hosting a variety of “tools” Twilight somehow procured in the short while they had agreed to this. Nevertheless, Celestia lovingly gazed over the selection and plucked a padded paddle for her pupil’s punishment.

She turned around to Twilight’s eyes gazing down to where her rump had been, and she smiled wickedly. “Eyes up, Sparkle! That’ll be another thing we’ll have to punish you for.”

Twilight was trembling, and Celestia knew it to be from anticipation and pent-up desire, not fear. As such, when she walked around Twilight, she trailed the tip of the paddle along Twilight’s side, the fabric of her blouse and skirt preventing her from directly feeling the smooth rubber tip of the paddle. Still, Twilight inhaled sharply and even let out a shivering gasp as the paddle slipped under her skirt, around her flank, then her rump, and then her other flank.

As the paddle came to rest on her dock, Twilight craned her neck around to face Celestia. “H-Headmistress, I have been a naughty filly. What is my punishment to be?” Twilight struggled to control her smile and keep her tone even, but the hints of anticipation still slipped loose.

“Eyes forward, barrel down, Sparkle,” barked Celestia. She snapped the paddle against Twilight’s dock, earning another yelp from Twilight, who obeyed the command.

With her chest and head pressed to the ground and facing forward, Twilight could only feel the paddle as it moved around her backside.

“I am going to teach you a lesson, Sparkle. And you will thank me for teaching you proper decorum, because you so desperately need it,” Celestia whispered huskily into Twilight’s ears. “I want you to count each strike and repeat back to me the ways a filly should behave at this school. Do you understand?”

Twilight nodded eagerly and replied, “Y-Yes.” The paddle in Celestia’s grasp traced along Twilight’s flank and a sharp blow fell on her right side. The pain shot up her leg and spine, and Twilight gave another shuddering gasp.

“Yes, who?” barked Celestia. “And count this!”

“One, and yes, Headmistress!”

“Very good,” Celestia simpered. Another blow struck Twilight’s right flank, this time slightly higher. “And what do we expect of young fillies at this school, Sparkle?”

Twilight gasped again at the blow, but her pitch grew higher. “Two! The school expects all fillies to show due deference and respect to their teachers at all times!” Twilight replied. The paddle traced it’s way across her rump, teasing just past her wet lips. Twilight gasped again and bit her bottom lip to stifle a moan.

“Oh my, Sparkle, it seems our little lesson is getting you all worked up. I should hope that you’ll control yourself until I’m done,” Celestia said as she deliberately rubbed the paddle hard against Twilight’s swelling nethers. A moan and a stuttered, “Y-Yes H-Head-Headmistress,” was the only reply Celestia needed before she brought the paddle back to Twilight’s left side and struck twice in quick succession.

Two yelps, the last higher than the first, and a shuddering breath came from Twilight. “Three, four! Fillies must keep to themselves, especially to avoid fraternization with their teachers!” Twilight didn’t know how much more she could take without being pushed over the edge; between the delightful and residual sting sending tingles up her flanks and spine and the wondrous way Celestia was indulging her and making the fantasy every bit as real as she dreamed earlier.

It seemed that Celestia was every bit as eager as Twilight to get her to finish, because she once again ground the paddle into Twilight’s nearly dripping slit. Twilight’s moan turned into needy, high-pitched whimper.

“Deary me, Sparkle, it seems we’ll have to make you clean the paddle when we’re finished. Perhaps you’d like a taste now?” Celestia whispered into Twilight’s ears once more.

Twilight nodded cautiously, and saw the rubber paddle already slick with her fluids pushed to her muzzle. She poked her tongue out and licked slowly. She savored her salty and surprisingly sweet flavor and as she was about to take another lick, the paddle was taken from her muzzle, to which she whimpered softly.

“Ah ah ah, we still have a few lessons left, Sparkle, and I’d hate to waste your time by cleaning this twice,” Celestia said sharply. She waited for a few moments, and then brought both her hoof and the paddle done to smack Twilight’s flanks. “And what do we say when somepony does us a favor?”

“FIve, six! We say thank you, headmistress! Thank you for the favor!” Twilight cried, then bit her lip again to stifle a very loud, lewd moan. Her entire body shuddered and she could no longer keep herself from needing release. “Oh, Celestia, please!”

“Very well,” Celestia replied sternly, “we will continue your lessons another day.” With that, Celestia took her hoof from Twilight’s flank and pressed it to her warm, wet lips and stroked up and down until her hoof was slick. Celestia swirled it around Twilight’s pronounced clit and each pass called forth more moans and whimpers of pleasure until at last the dam burst and Twilight tensed in her climax, briefly silent before letting out a long cry of ecstasy.

Celestia pulled her hoof back and awkwardly strode around to Twilight’s front and licked it clean in front of Twilight. She moaned lightly for Twilight’s benefit and kneeled down to kiss Twilight’s forehead. Twilight, now coming down from her orgasm, lifted her head and stole a quick kiss from Celestia’s lips. Celestia chuckled and smiled at her young student. She pulled Twilight to a standing position and helped her to the bed before summoning an ice pack and warm blanket.

“I take it you enjoyed yourself, my faithful student?” Celestia asked sweetly as she gently nuzzled Twilight’s neck.

Twilight nodded vigorously. “Oh, sweet goddess, yes! That was... beyond imaginably good. Like a dream come true.”

Celestia slid the ice pack against Twilight’s flanks and wrapped both of them in the blanket. “Good. And do you think you’d want to do this again?” Another vigorous nod. “Well then. Perhaps we can arrange for another rehearsal, unless you have other, ahem, desires?”

“Well...”
