Collection of short stories: Corrupted Equestria.

As soon as the sun disappeared below the horizon, Equestria was enveloped in darkness, replaced by a full moon that marked the onset of night. The alicorn sisters, who were standing on the balcony of one of the towers, breathed a sigh of relief. Another hard day is behind us, which means it's time to relax. And if ordinary ponies preferred reading a book or sewing, then the royal sisters had their own special method. Ordinary ponies didn't know anything about it, the servants and the aristocracy only speculated about what was going on in the princesses' chambers on the very last day of the month.

It was a kind of ritual. Similar to what the ancient ponies practiced, worshipping the stars as gods. Alternating every month, the sisters held this event to honor each other, along with the heavenly bodies they were responsible for raising. And the end of this month fell on the turn of Princess Luna, the younger sister of Celestia. Dressed in her night-black dress that accentuated her curvaceous curves, Princess Luna felt a small shudder, realizing that her time had come.

"Are you ready, Sister?" There was also a shudder in the younger princess' voice. It was obvious how eager she was to get started.

"Of course, Luna!" Elder sister's voice was calm and gentle, as befitted a monarch.

After receiving a positive response, the princess of the night begins the undressing ritual. Slowly taking off the golden dress from her older sister, unbuttoning button by button on the back, until finally she takes it off completely, defiantly throwing it on the floor. Then it's time for the corset, which is firmly attached to the lower back of the godlike pony. A blush flashed across Celestia's face, and her pussy between her hooves was soaked with excitement. Throwing aside her sister's golden tiara, Luna magically teleports the black panties into her hands, after which she slowly and gently pushes them into the salivating mouth of the princess.

"On your knees!" The princess commands in a whisper, as Celestia immediately carries out the order. Putting a pre-prepared collar and leash on her sister, the princess slowly begins to move, shaking with excitement, Celestia tries to keep up with her.

After going downstairs, the princesses continued their journey through the deserted corridors of the castle. They weren't afraid of being discovered, because during the day, Celestia had ordered the servants not to visit this wing of the castle after dark. Even the guards, who were supposed to protect the peace of their rulers, were sent to the barracks, despite the protests of the royal nobility. Just the thought of being caught made her younger sister's heart beat at breakneck speed. She wanted to start the second part of the ritual as soon as possible.

Slowly leaving the castle, the sisters went to the royal kennel, where the princesses' personal hounds were sleeping peacefully. The ever-vigilant pets heard their mistresses approaching and joyfully barked at the top of their voices, fortunately Princess Luna managed to cover the kennel with a dome of silence so that no one could raise the alarm. Kennel itself was divided into two parts, with Celestia's pets on the right and Luna's pets on the left. Without waiting for a command, Celestia turns her huge ass towards the cages. The smell of the perineal juice of the princess causes a wild desire for mating in males.

With undisguised delight on her face, the moon princess opens the first cage on the left, from which a muscular dog named Archie runs out to meet them. Without any foreplay, the beast climbs onto the back of the white alicorn, wraps his front paws around her waist, and then, with difficulty thrusting his huge cock into her pussy, begins to fuck. Trembling with excitement, Celestia barely restrains herself from resorting to magic, while Luna, unable to restrain her surging libido, begins to play with her pussy with her left hand, while continuing to hold the leash with her right.

In less than five minutes, the male begins to spew copious streams of sperm directly into the mare's uterus. Streams of semen rush in again and again, causing the mare's belly to get bigger and bigger. As soon as the first pet unties its knot, Princess Luna releases the second one and the procedure continues. Having driven all her hounds through her older sister, Luna pulls Celestia by the leash and leaves, closing the gate of the aviary behind her. Throughout their further journey, the seed kept flowing out of Celestia in a plentiful stream, which made it seem as if her womb was bottomless.

Their next route was to the royal forge, where the third part of the ritual would be performed. Descending into the room, the night mare smiled, because the blacksmiths did not even bother to put out the forge, which made the room very hot. Putting a bridle on her older sister's muzzle, as well as tying her hands behind her back along with her wings, Princess Luna sharply presses her sister's face to the floor with her right hoof, forcing her ass to remain in an elevated position.

"Tell me, Celestia, who do you serve?" Enjoying the process, the sister says.

"For you, mistress..." Celestia spat her panties out of her mouth. "And only you!"

"Well done, my pet!"

After waiting for the brand to heat up to the desired temperature, the princess, without any warning, cauterizes her sister's cutie mark, causing her to almost scream in pain. Without holding back tears, the older sister endures the repeated procedure without making a loud scream. The sight of her older sister's ass trembling with pain aroused Luna even more, from which she grabbed the whip lying next to her, starting to whip the poor pony's huge buttocks.

"Say it, bitch!" She did blow after blow. "Right now!"

"Long live the Moon! Long live the Night! Praise be to Princess Luna! Our true ruler!"

"And?"

"And fuck the Sun! Fuck Me!"

"Good pet!"

Feeling a burning pain all over her body, Celestia opened her eyes. She was in Luna's room, in bed with her. Looking at the sweet face of the sleeping sister, all the worries of the monarch disappeared. The ritual was over, which meant that it was time for night to turn into day. Standing with Celestia on the balcony of her tower, Luna could barely contain her gaze at her sister, who was covered with all sorts of insults personally addressed to her, scratches and bites inflicted in a fit of passion during their game in bed.

"Luna!" Celestia noticed her sister's gaze. "Is everything okay?"

"Tell me, Sister, you felt sorry for me, didn't you?"

"What?" she asked, not understanding.

"Every time it was your turn to bully me, you held back, right?"

"Yes, Luna..." Celestia suddenly hugged her sister. "Every time it was my turn, I tried to hurt you as little as possible! To be honest, this "ritual" was invented more for you, because I still can't forgive myself for your exile to the moon."

"Celestia..." youngest princess burst into tears. "You don't have to! It's been so long since then! And I don't need anyone but you! I love you, Celestia!"

"I love you too, Luna... You have no idea how..."
