Twilight had to slow down. Catch her breath. She took a look at her surroundings, and noticed she'd been subconsciously fleeing to her old room in Canterlot palace. Stamping her hoof on the tiled floor, Twilight turned back. She was going to see her brother, and she was going to have a word with him.
Yes, she had snapped at her friends. But why wouldn't they even listen? Applejack would be furious if some shallow mare were marrying Big Macintosh, wouldn't she? Twilight groaned in frustration and picked up her pace. She wasn't overreacting. She wasn't being possessive. Really.
“Twilight?” A familiar voice called from behind her. For what seemed like the first time in days, Twilight smiled.
“Princess!” Twilight responded, perhaps a bit too enthusiastically. Celestia stood behind her, her coat faintly illuminating the dim hallway. “I'm so glad to see you, um-”
As she approached the princess, Twilight faltered. She seemed exhausted. “Is this a bad time?” The unicorn asked sheepishly.
Celestia shook her head. “No, not at all, Twilight. I'm sorry, with all of Canterlot on high alert, I've barely had enough time to rest. How are the preparations for the wedding?”
Twilight looked away. “They're going fine, but there's something I need to talk to you about.”
Celestia listened patiently as Twilight pleaded her case against the brusque, prissy Princess Cadence. She actually felt a little silly, complaining about her soon-to-be stepsister to the princess who had been working tirelessly to keep her kingdom safe. But when she finished, Celestia nodded.
“I can't deny, she has been downright rude lately.” The princess frowned, “She didn't want to delay her wedding, so she took on all of the arrangements herself. It's clearly been wearing her down.”
“But she acted like she didn't even know me.” Twilight had meant that to be an angrier outburst, but couldn't bring herself to raise her voice. The princess - and, she supposed, her friends - may have a point, and arguing with her clearly worn-out teacher wouldn't help anyone.
Still, Celestia lowered her head to her student. “I'm sorry she hurt you, Twilight. I know she still loves you like a sister, and she must feel guilty about the way she treated you. Try speaking with her after the rehearsal tomorrow. I'm sure that once she's clearheaded, you two will have a lot to catch up on.”
“Of course.” Twilight said, her gaze meeting the floor. Had she really felt so angry over this? It was more than silly, it was plain embarrassing. “I'm sorry, princess. I shouldn't have kept you up for this.”
With a sagely smile that never failed to reassure Twilight, Celestia brushed her neck against the young unicorn's. “No need to be sorry. I always have time for my favorite student.”
Feeling the princess' glowing warmth against her, Twilight felt herself start to push her muzzle against her teacher's soft coat. The princess' scent was intoxicating – like a bright spring morning in a dew-covered field. Twilight knew she shouldn't start doing this in the middle of the castle corridors, and she had to repeat this to herself several times before she pulled back.
“Um. Princess?” Twilight asked, her voice barely above a whisper and her face feeling very, very hot. “Maybe after the wedding, I could stay for a couple of extra days?”
Queen Chrysalis didn't just feel that. She couldn't have. There was certainly affection between the two of them, but when the young mare pressed against her neck, it almost felt like-
“I haven't had, um,” Twilight stumbled over her soft words. Her eyes would meet Chrysalis' and then dart away just as quickly. “A private lesson in quite some time.”
It took everything in the changeling queen's power not to burst out laughing. This was too precious – the all-powerful, always-benevolent Princess of the Sun, illicitly involved with her star pupil? Sure, the love between a devoted student and teacher was certainly enough to quell the suspicion in Twilight's heart, but this was something much, much deeper. Chrysalis' mind raced with the possibilities.
“Twilight,” The queen gently cooed in Celestia's voice, ever so lightly touching the unicorn's nose with her own. “Like I said, I always have time for my favorite student.”
The bated breaths Twilight took in as they stood, lips just barely apart, were exhilarating to the queen. She felt the desire pulsing deep within Twilight, so close she could devour it all right now. But she had to be patient. Stealing love is a delicate art.
“And since you're overdue, I must insist you have a lesson immediately.” She grinned.
“Right now? I-” Twilight stammered, her struggle useless against her pounding need. Chrysalis had influenced her desire by only the slightest of margins, and it was already drowning out her few conflicting thoughts. “Maybe we could use my old room?”
“Lead the way, my dear student.” Chrysalis turned to follow Twilight as she climbed a nearby set of stairs, leading to a posh penthouse observatory. The queen wasn't even sure if the giddiness she felt was her own anymore. She could just lean forward and taste the horny student's slick sex. See what noises she would make when her beloved mentor makes her cum. Patience, Chrysalis ordered herself as she bit her lip. Patience.
Twilight led her to a bed hidden in a nook between bookshelves. Dark blue moonlight shone through a skylight high above, and Celestia's dimly glowing coat cast small shadows around the pair. Twilight sat at the edge of the bed, her face remarkably serene for the intense need Chrysalis felt from her.
“What sort of lesson do you have for me tonight, princess?” Twilight asked with a sultry tone and the hint of a mischievous smile on her face. Chrysalis couldn't help but wonder what Celestia had done to this girl.
Oh. What had Celestia done to this girl? Twilight was being driven wild with arousal, but that would mean nothing if Chrysalis blew her cover. Especially if this pony was as magically unstable as she'd heard.
“My good little student,” Chrysalis matched the unicorn's sultry tone, dragging out her words as she frantically pieced together an answer. “I, uh, would like you to show me what you've learned. You have been keeping up with your studies, haven't you?”
“A test?” Twilight gasped, a gleeful smile momentarily breaking through her coy pretense. Chrysalis breathed a slight sigh of relief as Twilight edged backwards, beckoning her onto the bed. “I'm more than prepared.”
Chrysalis stepped onto the bed, pressing Celestia's luminescent coat against Twilight's warm, eager body. As the unicorn's tongue slipped into her mouth, the queen felt Twilight's love begin to pour into her. Pure, filling, and ecstatic – she pushed against her, demanding more. Twilight's breaths were getting shallow, her tongue was barely keeping up with her teacher's desperate thrashing.
Twilight pulled away, panting. Almost insulted, Chrysalis opened her eyes to see Twilight staring back, her eyes blank and tinted the slightest bit green. As the queen leaned in once more, Twilight shook her head and turned away. The green light in her eyes had gone.
“Princess,” Twilight said with a coy smile, “I'm flattered, but I need to focus on my exam.”
Twilight kissed and licked Chrysalis' chest, inching further and further south. Leave it to Celestia to train her student to be the ultimate tease. She yearned for more love after feeling that burst of passion. Each little lick felt like a drop of water after a monsoon, and Chrysalis wasn't sure how much more she could take.
Her tongue stopped just short of Chrysalis' needy pussy. Resting her chin on the changeling's groin, Twilight shot her supposed mentor a devilishly sweet smile.
“Judging by how soaked these sheets are starting to get, I feel like I'm off to a good start.”
Chrysalis groaned as Twilight's tongue pressed against her. Her initial licks were slow, just within Chrysalis' lips. Each drag of her tongue pushed slightly deeper and deeper into the squirming changeling. Every once in a while Chrysalis would feel Twilight's soaked muzzle press against her, and that hot tongue would explore her so thoroughly. The queen's mouth began to loll open, her ecstatic moans building in volume. This girl was unrelenting.
“Gosh, princess, have you missed me that much?” Twilight chided, withdrawing her dripping muzzle briefly. “I shouldn't get too cocky though, so just in case...”
As Twilight's horn began to softly glow, a lewd groan escaped Chrysalis' throat. She felt a hot, slick tongue press up against her tender rear. The queen writhed helplessly as the smooth tongue entered her, slowly kicking her rear hooves against the bed.
“I had a feeling you'd enjoy that.” Twilight grinned before returning to the changeling's pussy. Her tongue pushed and caressed Chrysalis' folds, every so often teasing the queen's stiff clit. The second, magical tongue Twilight had summoned seemed to lengthen, wriggling and thrusting further into her tight passage.
Chrysalis could barely control the loud, gasping moans that the twin tongues forced out of her. Never had she been pleasured so thoroughly before – so many memories of mares, stallions, changelings of all kinds suddenly seemed bland compared to the moist unicorn muzzle lowly moaning inside her. Her physical ecstasy entwined with the raw bliss that gushed from the hungrily lapping Twilight. So happy to lose herself in the scent and taste she had been without for so long. So happy she could still make the great princess of Equestria squeal and moan and so very wet.
The little unicorn squealed herself as she felt Chrysalis' hoof on the back of her head, urging her on. The disguised queen felt her climax building, pulsing stronger within her. As the tongue in her ass began to speed its thrusts, the changeling queen found herself overwhelmed by the warm unconditional love that poured from the unicorn's addled mind and frantic tongue. With a loud, echoing cry, Chrysalis' hot juices burst from her, spattering onto Twilight's back and mane. Spurt after spurt of the ecstatic queen's fluids coated Twilight's already moist face, still half-buried in the brightly glowing nethers of her supposed mentor.
The air around them was heavy for a time, hot with the pair's sweat and filled with the sound of their panting. Finally stretching her sprawled-out hooves and flopping over onto her belly, Chrysalis shook little disheveled wisps of Celestia's mane out of her face.
“That was,” Chrysalis couldn't help but be honest. “That was wonderful, Twilight.”
There wasn't much of a response, some quiet noise muffled by the sheets. “Twilight?”
The unicorn's muzzle was flat against the damp sheets. Chrysalis cautiously rolled her over and grinned. Twilight's eyes pulsed with a very slight green hue.
Chrysalis wrapped herself around Twilight's little body, nuzzling against her wet muzzle and breathing in her own scent. She whispered, “How do you feel, Twilight?”
“Happy. Fuzzy?” A small giggle escaped from the entranced Twilight. Those pulsing green eyes met Chrysalis', who kept her calm facade while gorging on the devotion that radiated from Twilight's body. She mumbled, “Wasn't I...wasn't I going somewhere? I thought there was something important I needed to do...”
The queen silenced Twilight with a kiss. The unicorn was almost hers, but she was a resilient one. Some small bit of free will was fighting with everything it had, trying to wake Twilight from her stupor. Fortunately, after that astounding display of affection, the haze over her mind was very strong indeed.
“I want do to something for you, Twilight.” Chrysalis spoke, her lips brushing against those of her hazy prey. “You made me feel good, better than I've felt for a long time. Besides,” Twilight began to softly moan as Chrysalis' hoof teased her drooling pussy. “...You were so patient while you pleasured your princess, you certainly deserve a reward.”
“B-but,” Twilight struggled with her words. She was aware of a distant, nagging thought, but she felt so hot. The scent of their sweat so fresh in her nostrils made it so difficult to think. Her words felt slippery. “I thought that...there was something important I was going...to?”
Resistant minds were always so thrilling to play with. Chrysalis used to be frustrated when her prey fought back, but feeling her quarry internally thrash about as they shamefully obeyed her every order was almost as intoxicating as love itself.
“You were looking for me.” The queen spoke sweetly as her hoof rubbed Twilight just a little harder. “You said you'd missed me so much, and hadn't had a lesson in so long, remember?”
“Y-yes,” the little unicorn grunted and gasped as her fluids dribbled down Chrysalis' hoof. She didn't remember, but it was just easier to agree. After all, the princess would never lie to her, would she?
“Good.” Chrysalis licked Twilight's cheek, and withdrew her hoof. “Now, get up and present yourself to me.”
Sluggishly, Twilight shifted, standing unevenly on the bed. She turned, her hindquarters and dripping sex inches from Chrysalis' face.
“Princess?” Twilight quietly asked, her confused words slipping through her slight, serene grin “What are...what are you going to...”
“Shh,” was all Chrysalis said before pushing her horn into Twilight. The unicorn grunted as the long, twisting horn inched deeper inside her tight, dripping hole. It started to hurt a little, but this was what the princess wanted, and Twilight couldn't disobey her princess.
Almost fully hilted inside the squirming unicorn, Chrysalis' horn began to glow. Twilight gasped as electricity seemed to surge through her, her eyes shining the brightest green.
All of a sudden, Twilight felt as though she was floating somewhere distant. The musky air of the bedroom and her beloved princess far away. For a moment, there was silence. Then, slowly, sounds and sights began filtering in. The first thing she heard was Rarity, doing her best to instruct Twilight on proper magical and oral stimulation through her delighted squeals. She felt Fluttershy's hot, wet thrusts, humping the double-ended dildo between them. The musky taste of Big Macintosh's cock, coupled with the smell of hay in the dark barn.
More sensations assaulted her, each more vivid and more thrilling than the last. She was laying on Applejack's gently rising and falling stomach, her tongue meeting Rainbow Dash's inside the earth pony's slit. She heard Pinkie Pie's muffled moans as they kissed, stallion seed splattering over their faces from the eager cocks surrounding them. She felt Spike's arousal press against her as he begged her, just this once, the princess wouldn't have to know.
So completely lost in the fantasy she was being fed, Twilight began grinding against the brightly glowing horn inside her, her blank eyes staring into nothing tongue hanging from her mouth. Chrysalis chuckled with delight as she gorged on the most intimate memories of Twilight's beloved friends.
Twilight was losing focus. So much overwhelming pleasure at once – she couldn't keep track of where it came from. Those ponies who loved her and who she had loved in return all started to seem like faceless, blurry figures. Slowly they disappeared, leaving only the pleasure that Twilight so desperately held on to. She feared those sensations would be all she had left.
And then, once last memory surfaced. In the very same room, on the same bed, many years ago. Nervous, gentle kisses between a monarch and her specially chosen student. All of the other pleasures faded away, replaced by the feeling of the princess' radiant body against her own. As they touched, Twilight found herself staring into the princess' beautiful magenta eyes. The thought of there being any other pony she'd loved as much as Celestia was just silly – hadn't it always been just the two of them? The truth was so obvious.
She loved Princess Celestia with all of her heart.
The illusion broke. Twilight's juices ran down Chrysalis' horn, dripping over her face and wickedly grinning muzzle. The changeling withdrew her damp horn, letting the trembling unicorn collapse once more, panting hard into the messy bed.
Chrysalis stepped off the sheets, standing before her wholly ravaged prey. Upon hearing her name, Twilight opened her green, glowing eyes, a dopey smile spreading on her muzzle.
“Do you love me, Twilight?”
“I love you, princess.” Twilight spoke in a blissful monotone.
Celestia's image burned briefly, consumed by green flames as Chrysalis shed her disguise. The jet black changeling queen brushed a hoof through Twilight's unkempt mane.
“I'm not the princess.” Hearing her own voice again was always such a pleasure. “I stole your brother's bride and made him my slave. When he and I are wed, I'll destroy Celestia and all of Equestria will be mine. You wouldn't dream of stopping that, would you?”
“Of course not, princess.” Twilight nuzzled Chrysalis' pitted hoof, her eyes glazed and half-closed.
“Good.” Chrysalis' long, serpentine tongue flicked from her mouth and gently licked the dazed unicorn's horn. “I should keep you, Twilight Sparkle. You were so clever, I would just love to make you my dumb little slut. Would you like to be my plaything, Twilight?”
“Yes, princess.” Twilight nodded. She would like to make her princess happy more than anything.
“Such a good girl.” The changeling queen grinned. “Now, clean yourself up. You've just spent a wonderful evening catching up with Cadence, who apologized for her rude behavior. You're no longer worried and can't wait to be your brother's best mare.”
“I can't wait.” Twilight echoed as she stood, slowly walking to the small bathroom at the other side of the room. Chrysalis stretched her wings and licked her lips – she hadn't expected to gain so much power so soon. Still, she would play it safe. With the devotion of Twilight and Shining Armor at her disposal, Celestia herself might not even stand a chance. Relishing the thought of her brood effortlessly conquering Canterlot, Chrysalis disguised herself as Cadence once more, quietly exiting the room.
Twilight awoke on the floor next to her bathtub. She felt clean, her mane still wet and the air still slightly steamy. For a brief moment, she wondered what she was doing in that old bathroom. But her lovely night with Cadence quickly came back to her. How dreadfully sorry Cadence had been, and how they'd spent the rest of the night laughing and joking, just as they had when she was a filly. Twilight sighed, wondering how she could have judged her old friend so harshly.
Oh well, she thought, picking herself up and levitating a towel around her mane. She needed to get back to her suite. There was so much to prepare for the big day.
As she left, Twilight thought she saw the bathroom mirror reflect a strange glint in her eyes. She shook her head. It was probably nothing.
