My Dearest Twilight,
You are cordially invited to my humble abode, where we may have a crisp dinner, or a drink, and talk over your recent studies. You last letters are intriguing and I think your skills have increased greatly. If you oblige to arrive, I would be jubilant.
Your Mentor,
Princess Celestia
Twilight rolled up the parchment and set it back onto the birch desk, a light sigh escaping her slowly. With a light spring, the violet pony trotted down the stairs, a bright smile upon her cheeks, her chest burning. Did the Princess truly want to see her? Did she really want an interview, to talk over her latest studies? Twilight smirked, biting her lip.
"Spike!"
"Yea. . .?"
"Will you watch the Library while I'm gone? I need to head out somewhere." Twilight called to Spike, who was snoozing in his basket. The baby dragon groaned, and rubbed his eyes. Laying in bed, thinking for a couple heartbeats, he finally answered his friend.
"I will!" he called back, grumbling before throwing his blanket over his head and slipping back into the peaceful sleep he was in before. Twilight nodded to herself and opened the door, stepping outside. Blood scarlet and light pink touched the sun. It had to be an early dusk. Hearing the call of the train, as it bellowed loudly set Twilight in motion. She galloped down the cobblestone roads, ponies whispering a 'Hi' to her as she quickly passed. It wasn't too soon until she was near the station, signing a ticket out and boarding the train. Twilight felt this was all a little quick, but she quivered with excitement yet, watching the world of Equestria speed by as the train chugged on.
The shouting of the conductor jolted Twilight out of a soft nap she was drifting in an out of. The pony jogged past seats and off of the steam beast. She thanked the conductor, whom tipped his hat off to her as she got off from the train. The violet pony started towards Canterlot, a fire burning in her heart. She looked onward, eyes twinkling with an image of the castle.
Soon, Twilight was nearing the Princess' castle, next she was bowing to her mentor, and the last thing she new, she was in Celestia's quarters.
"It's nice to see you, Twilight." Celestia said, a soft smile upon her radiant face. Twilight returned the smile.
"Nice to see you, too, Celestia." Twilight curtsied. The Princess' eyes traveled around the vulnerable pony's body. Twilight looked at her mentor, a questioning urge spread about her face. The Princess ignored this, and motioned Twilight over to a small table, where she already had tea and some confections prepared. Using a soft rosy magic, Celestia poured some amber tea into the cups, and took a small muffin.
"So, Twilight. I see you received my parchment, for if you didn't. . . you wouldn't be sitting here." Celestia chuckled, sipping the tea. There was some tension in the air though, like electricity. The air felt hot, and the anxiety hung in the breath of both ponies. The fireplace on the other side of the dim, but well lit room coughed and sparked, a log jumped and the flames crackled.
"Yea. . . you sent the invitation for a review. Or some talk about my latest letters." Twilight responded, whom Celestia nodded softly. The two sipped their amber tea and bit into their muffins.
After maybe after a half hour, the two had finished three cups of tea, and a few muffins, Celestia decided to make a move. The two were sitting in front of the fire, small conversations of the letters still hung around, but Celestia moved closer to Twilight, wrapping her wing around the small pony. Twilight let out a small gasp resembling a girly squeal. She looked at her mentor, who also looked at her. The Princess smiled sheepishly.
Twilight had actually really had affection for the Princess for a while. This could be the perfect time to let her erotic fantasies to come true. Her breath coming in quick, Twilight kissed the Princess, her tongue wrapping around the Alicorn's, saliva now a cushion for two pieces of flesh, lips colliding, bodies warm. . . The Princess grinned. This is what she wanted. The Alicorn was soon over Twilight's small build, hooves caressing soft hips, tongue licking around lips, lustful looks toward each other.
Celestia broke from Twilight, licking lips. She put Twilight's entire horn into her mouth, licking around the base and circling the shaft of the horn. Her tongue lulled around the tip of the magical appendage, Twilight moaned and twitched, grinning sheepishly. Celestia put her hooves around Twilight's hips once more, massaging her slim form. The Princess worked her hooves and tongue, while Twilight kicked softly, her horn gaining a dim magenta glow. Tia worked at the unicorn's horn, her face burned with a deep flush, until Twilight squealed, a small spark of magic flew like a firework. The next thing Twilight new, she was drifting off with a Celestia over her.
Twilight awoke with deep purple panties put upon her rear, the lace meshing a web over a wet marehood, which made beads of fluid on the undergarments. She also awoke in a dim bathroom, where a large sort of bathtub bubbled on the other side of the room. Candles lit the dark, romantic area. Petals scattered upon the floor. Celestia was sitting in the tub, her mane soaking wet, and eyes locked on Twilight's burning body. She stuck her tongue out, and panted like a young puppy. She giggled and motioned her student over. The lilac pony gulped, and walked over. The panties chaffed and the wet of her marehood brushed against her fur, creating cold, wet feelings. Twilight slipped into the water.
Celestia spoke for the first of the hour.
"Face that rump towards me, student." She barked in a commanding, but lusty tone. The candles flickered, and a soft breeze from an open window eased the petals around the marble floors. Twilight flushed, and stuttered an objection. The Princess put a hoof to her lips, and nodded. Twilight turned, her chin touching the water, her rump in the air and facing towards her hungry mentor. Tia licked her lips and swam forward, hooves caressing cheeks, and teased at wet panties. Twilight clenched, letting out a sigh, panting.
She pulled down the coverage, and giggled at the set laid out before her.
Thick, magenta lips, beads of sex fluid, and the small throb of her marehood as she breathed. Celestia let her tongue slide over the folds, where she got a shiver out of her subject. The Princess tickled her labia, and nibbled on the love bead. Twilight squealed and a trickle of fluids kissed the lips, and trailed down her legs, into the bath water. Celestia licked these juices, sticking her tongue out, dribbles of saliva and Twilight fluids covered her mouth and coated her tongue.
