Welcome to the Show, Twilight

Twilight shifted nervously and licked her lips as she moved over to the desk with Celestia, “I-I’m worried about the fangs,” she admitted, “Y-your’re so big.”

Celestia shook her head and smiled at her, “I’m sure it would be fine, my little cocksleeve. I have had Thestrals before. But that’s not what I have planned today, today I want your cunt.”

Blushing dark red, Twilight shook her head, “T-that’s never work! You’re too big!” she protested.

“I’m too big for your throat too,” Celestia teased and then leaned in to whisper, “I cheat,” into her ear.

“H-huh?” Twilight asked, blinking up at her, “Cheat?”

“Mhmm,” the white alicorn agreed, “It’s enchanted.”

Twilight stared up at her and then glanced down at the massive cock, “...You enchanted your penis?”

“If I didn’t, I wouldn’t be able to fuck anypony. Maybe a dragon at most,” Celestia said with a grin, “Then what would we do?”

“W-what does it do?” Twilight asked as she eyed her teachers big cock. It was longer than Twilights right front leg and significantly thicker.

“It’s not that complicated,” Celestia said and pulled Twilight into a quick cuddle, “It shrinks when entering somepony. But only to the limits of what they can handle, maybe stretching those a little. So don’t worry my little cocksleeve, it’ll always fit you, no matter what.”

Twilight nodded and then hesitated, “B-before we start, d-do you mind if I… explore?”

Celestia smiled and then nodded, “Go ahead, Slutlight. But do be quick about it, I can only work with one of my cocksleeves around me.”

Blushing brightly, Twilight scooted down beneath the desk where Celestia guided her before scooting around beneath the massive desk to gaze at the big cock before her.

On any other pony, it would have looked out of place. On Celestia though… it only looked gigantic.

Swallowing nervously, Twilight scooted in to nose along the massive cock, extending her lick to slowly lick.

That scent, that taste… feeling them again, made her press close and soak them in, first now realizing how much she had missed them from last week.

She almost felt a bit disappointed as Princess Celestia gently guided her away with her hoof,

“Go on, Slutlight. I know you love it, but we have work to do,” Celestia teased and stroked her ears, “Go on.”

Breathing slightly heavy, Twilight blushed and nodded before scooting around beneath the desk before raising her rear and tail.

“Relax, my little cocksleeve,” Celestia said and stroked her cutie marks softly with her hooves, “You have already taken it once already.”

Twilight managed a small nod before gaspíng as the big cock tip pressed against her soaking wet pussy before whimpering as Celestia started to push inside.

“T-too big!” Twilight moaned and groaned against the floor, rubbing her hooves against the fine wood as Celesita pulled her backwards without mercy.

That massive shaft felt like it was splitting her in two, it felt like she was trying to take one of the castle towers! It made the buttplug spreading her rear wide feel small!

“P-princess!!”

“Hush, my little cocksleeve,” Celestia cooed and then pulled her back firmly, thrusting in to hilt in the smaller alicorn, making Twilight let out a sound she never had before, her eyes rolling back slightly in her head as she trembled.

Shuddering, Twilight felt so incredibly full, the cock spreading her pussy to its limits and despite herself, she tried to tighten even more around it.

“Mmm. Now you are where you belong, be quiet. I need to get some work done,” Celestia said and started to slowly roll her hips, just thrusting a couple of inches at a time.

Twilight just moaned against the floor for a second before a hoof smacked her cutiemark, making her clamp down and tremble!

“Hush, cocksleeve,” Celestia chided her, “I need to focus on my papers. I can’t do that if you keep making sounds.”

“S-sorry Princess…” Twilight choked out before covering her mouth with her hoof as the larger alicorn started to roll her hips again.

In her teens, Twilight had had more than one dream about Princess Celestia. The thought of nuzzling in between those thighs, to lick and nose along those feathers. To be pressed down beneath that beautiful alicorn.

To be spanked for being a bad filly.

But this was… oh Celestia…

Forcing herself to move, Twilight pressed her lips together tight and tried to stay quiet as she put her hooves on the floor and started to press back against her teachers small thrusts, each one sending a ripple of happy shudders through her body.
