Sunrise

Twilight stumbled down the hallway, using the cold stone of the wall for support. The guards ignored her as she passed by on her way to one specific destination. A few snickers chased her into her Mistress' bedchamber as the full power of the drugs she had taken kicked in. Her mind was fogged over with lust as her glazed eyes scanned the room. A deep sniff brought her own potent musk into her senses along with the smell of the Empress. The dark queen was lounging on her bed, free of regalia.

The drugged unicorn stumbled to the bed and climbed on, leaving a trail of drops behind her from her sopping wet marehood, "M-Mistress... I-I'm heeeeere," she moaned lustfully, collapsing on her side and running a hoof between her legs. Twilight brought it up to face and licked it, gazing at her beautiful queen through half-lidded eyes.

"Ah, Twilight... I know I don't need to drug you anymore, but it is so much fun to see you like this," the nightmare before her said as she shifted, revealing she had indeed used a gender manipulation spell at some point in the evening. Her stallionhood was long, jet black, and hardening quickly from the scent of mare in the air.

"A-ah... Mistress... Is that all for me?" the unicorn asked, inching closer to the extended penis in front of her. She drew a breath in and almost came just from the musky smell of her Empress' groin. It was strong and male and her body needed it now. Her tongue slithered out and took a lick to help coax the erection along. Above her, she heard the alicorn gasp softly. Encouraged, the drugged mare planted some soft kisses along the other side before placing her mouth over the flare and taking as much as she could down her throat.

"Oh, my pet..." was all Nightmare Moon said as Twilight continued to suck on her temporary maleness. The Empress was enjoying her prize's oral ministrations. The mare had a talented tongue in more ways than one. Tempted to release her seed into the young unicorns mouth, the dark queen held back. Levitating over a spreader bar, some rope, and a set of blinders, the alicorn proceeded to truss up her pet with a practiced hand. A thousand years of practice makes one very efficient.

Unable to move and unwilling to protest, Twilight simply let out a low moan as the cock was removed from her mouth. She felt the weight and heat of her Mistress move behind her and soon the tip of that monster was resting just at the entrance to her marehood.

"It is time," the queen said, slipping the flare of her penis inside. She pressed forward until she felt the heat of Twilight's estrus on her balls. Moaning loudly, the alicorn began to thrust inside of her pet. The oral pleasure from before had built her up to a peak, but she was old, wise, and under control. This was a special night, and she wanted her pet to enjoy it as much as she did. Leaning down, the nightmare began to whisper into her lover's ear.

"I am going to rut you, Twilight Shadow, like I never have before. My seed will soak into every inch of your womb this night. There will be no doubt that you will be carrying my foal. You are powerful in your own right, and will serve well by my side. I grant you this gift on this night, a thousand years from the moment I sealed Celestia away. Now, Twilight Shadow, take my colthood and bear my foal!" the Empress of the Night crooned, punctuating each sentence with a particularly vigorous thrust from her powerful haunches. At the conclusion of her speech, she planted the flare of her cock up against the very entrance to her pet's womb and came, filling the insensate mare with cum.

Twilight's vision exploded in stars as her mind stored that speech away for processing when the unicorn had sobered up enough to understand any words beyond rut, foal, and seed. At the moment, the only she cared about was receiving her mistress' seed and feeling that magnificent colthood thrusting in and out of her folds. True to her word, Nightmare Moon recovered from her orgasm and began to rut again. Twilight barely had time to come down from her first orgasm before another began to build.

Hours later, the sodden, cum-soaked mess formerly known as Twilight Shadow collapsed on the messy sheets of the bed. Her eyes were completely glazed over in pleasure as her mistress' seed leaked freely from her marehood and down her leg to pool with her own feminine juices on the silk beneath her. The queen of the night, meanwhile, simply lay next to her pet, with a pleased smile on her features.

The unicorn in front of her would be out of it for a few more hours at least, so she summoned her maidservants and told them to get Twilight cleaned up and into her chambers to rest and recover. They looked at the mess they would be dealing with and sighed, one unicorn levitating the entire bundle towards the hallway while another began to clean the bedding. They placed the mare in her tub and ran a bath, cleansing her fur of the sweat and other fluids of the session with vigor. They did not, however, dare to remove any of the Empress' seed, using a magical plug to keep any from leaking out into the bathwater.

Once the Mistress' pet was clean, they put her to bed, positioned comfortably so that no further leaks would occur. They then proceeded to make snide comments about her as they exited the chamber and returned to their usual duties. Twilight's slumber came quickly after the relaxing bath and her mind passed into peaceful oblivion in no time at all.

Several more hours passed by unnoticed by the sleeping mare before she was awoken by a hunger that she had not felt in a very long time. Hours of being used and abused had left her flank sore and her limbs stiff while draining her energy reserves to the bare minimum allowable for consciousness. Her mouth was dry and her tongue felt as if it was made of some particularly rough cotton. Smacking her lips a few times, she managed to gasp out a weak shout for her draconic minion, "Spike..."

The purple dragon appeared out of nowhere as was his wont, "Yes, my lady?"

"Get me some food... and something to drink..."

"I had a feeling you would need refreshment when you awoke," he said, producing a large pitcher of ice water and a perfectly portioned salad with fresh daisies and shredded carrots.

The unicorn greedily drank from the pitcher, not bothering with a glass at first until she had quenched the thirst that threatened to drive her mad. After she recovered some of her dignity, she took the salad and began to consume it at a pace faster than she would have liked. Finally sated, the mare sipped at her water and sighed, "Thank you, Spike. What would I do without you?"

The dragon just smiled and shrugged before slinking off to wherever he vanished to when he was not needed. Twilight watched him go for a moment before stretching and trying to loosen the muscles that her Mistress had worked so hard last night. The speech she had been given finally rewound and played again through her mind. It had been a special night. Her seed was potent. She had not been given anti-pregnancy herbs. Estrus had been induced. Her Mistress mentioned a foal.

The thoughts rolled around, Twilight's usually keen mind unable to grasp everything at once for a moment before it suddenly struck her like a lightning bolt. Her magic faltered and the glass of water fell to the floor and shattered as her shocked voice echoed through the otherwise empty chamber, "I'M PREGNANT!?"
