Dust and other particles filled the air and Twilight Sparkle held her breath for a moment to avoid getting said cocktail of allergens into her nostrils. For the last hour she had furiously read every single word in this chapter of this very special book, courtesy of the royal library, and finally, she had memorized a very special spell, which she was now hankering to use.

A wave of nostalgia came over her as she levitated the book towards the pile in the corner of her room at Canterlot castle. How many days had she spent in here, studying under the caring gaze of her beloved teacher.

Time to turn the table on one of those facts.

Twilight jumped off the bed and left the room, eagerly giggling to herself.

This was going to be good.

She hurried through the corridors and finally found herself in front of a broom closet. The unicorn waited until the corridor was empty and finally hurried inside, closing the door behind her.

She let out a final giggle and focused her magic on the words she had learned.

Seconds later, her horn began to glow and an invisible ray of magic radiated straight ahead, right through the walls in front of her. It was invisible to others, only allowing the caster to see through layer upon layer of massive surfaces, letting only living beings remain visible. It also allowed advanced manipulation of said objects in the way. Originally, it was meant for searching lost ponies in caves. But ever since the mines below Canterlot had been closed, it was used less and less due to it's... less than noble potentials.

Twilight's current use was a more than ignoble.

After all, the beam was directly aimed at the royal quarters, in that one blind spot she had opened yesterday for this exact deed.

And in her line of sight was none other than Princess Celsetia of Equestria,

The white alicorn was resting on her favourite rug, legs beneath her, book in front of her and focus completely onto her reading.

Twilight smacked her lips. She had a perfect view of Celestia's delicious, round haunch. Only the waving, flowy tail censoring the most private parts of the sun princess. Twilight couldn't hide her grin. Oh, how often she had to fight the mesmerization of seeing the royal flank move before her eyes. And there they were!

Now she had to be careful. Celestia could not see her, but she would see the purple glow of magic, so Twilight had to activate and deactivate her spells quickly.

She began by moving some air, having it blow across Celestia's back between her wings. The princess shivered and shifted a bit. Her head moved, apparently looking for the source of the draft.

Twilight let out a giggle and waited until the princess returned her focus to the book. This time, Twilight sent a shiver over Celestia's long neck and her grin broadened as the alicorn shivered yet again, her tail swaying from left to right, revealing just a little of the soft flower of marehood that Twilight had spent her entire adolescence desperately not looking at. Oh, how she wanted to just jump in and kiss and lick and nibble and bite until even the regal princess was pile of moaning putty in her hooves.

Celestia settled again after a little while and Twilight decided to go a step farther. Carefully, she ran a soft wind over the arms of both of Celestia's wings, the place where most of the nerves resigned. Celestia trembled under the touch, shaking her head in both surprise and something else. The alicorn shook her wings and Twilight mercilessly attacked the roots of her wings, first with wind, then with a quick touching. Celestia let out a long sigh and her wings spread in sudden arousal.

The princess rose and looked around desperately, prompting Twilight to stop.

She quelled the spell and stepped outside of the closet. She wanted to go on, but Celestia would certainly resist at first. For now, she would wait and take care of the glistening wetness that was dripping from her hind-lips.

Celeastia meanwhile let out a sigh and shook her head. "At least she is letting her deviant tendencies out on somepony who actually doesn't mind them... My most faithful student..."
