Bound nuzzled Twilight’s cheek, then gave it a lick before stepping onto the platform, making the car wobble slightly once his last hindpaw left the train and touched down onto the cold crystal. He looked back at her with a smile, watching her wave as the door closed, and continued to watch her as the train left until he could no longer see her.

He turned and carefully plodded along, careful not to jostle the royal sisters snuggling on his back, deep asleep since their attempts at creating prototype musk candles, which resulted in both their asses, their muzzles, and Celestia’s pussy being pumped with his puppy batter, which currently leaked from their crotches and matted Bound’s fur.

As he stepped off the crystal train station onto cold hard ground, he was met by a pair of crystal guards.

“Bound Hooves?” one of the guards called. Bound’s ears perked up at his name instinctively, which the guard noticed. “Follow us.” They turned in tandem and began marching towards the large castle in the center of the Empire, and Bound promptly followed. The doorways in the castle we're luckily big enough for him to squeeze through safely, and they arrived in the throne room within a half hour.

The large throne room doors swung open to reveal Princess Cadance sitting on her throne with a chipper smile, who was also fully in the nude, at his request.

“Welcome!" Cadance chirped, springing from her throne into the air and gliding to land in the middle of the room. He could tell she enjoyed not being bogged down by her royal outfit, which he was certain was made of pure gold, watching her bounce around the large room in their vague direction with her wings wide open, until she eventually skidded on her to a stop in front of them.

“Nice to finally meet you!” She exclaimed excitedly, leaning forward until their noses were smushed together and she stared into his eyes with her purple pupils, sparkling with childish glee.

“Nice to meet you as well," Bound replied and licked her lips, making her giggle.

“Cady!" Celestia suddenly exclaimed, hopping off his back and wrapping her in a hug.

“It had been a while," Luna said, hopping off with a smile as she watched them embrace.

“I can't wait to catch up with you!" Cadance exclaimed as they pulled apart and Bound sat.

“After the spell," Bound reminded her.

“Yes after that," she added. “Oh! That reminds me!"

Cadance turned and jumped forward, then pressed her chest against the ground, letting her forelegs extend out under her as she spread her hindlegs and flagged her tail.

“I want Bound to use me as his cum dump first!" She explained happily.

“For how long?" Bound asked, raising an eyebrow.

“However long you want!" She chirped, swaying her hips. “Well, as long as it's less than an hour." She giggled. “I do have other princessly duties to attend to."

“If you wish," he told her. “But first, I request that you cast that hermaphrodite spell upon yourself.”

“Why?" She asked. “Is my pussy not enough?"

“Your pussy is plenty enough," he told her. “I would just like a unique experience."

“Lucky for you, I'm an expert at providing unique experiences!" She chirped, and with a flash of her horn, a thick cock and large balls colored the same as her fur popped into existence between her thighs.

“Now onto your back," he ordered. She obeyed in a strange way to avoid hurting her wings, jumping and spinning mid-air before landing on her back with a thump and an oof.

“Now, while I take your pussy, I will have Tia ride you, and Lulu will sit on your face,” he explained as he approached, standing over her before sitting just behind her. Soon, Luna trotted over and stood in front of Cadance while facing away, before sitting atop her pink muzzle with a sigh.

“Face me, Lulu,” he told her, and she obediently turned, letting Cadance wrap her forelegs around her aunt’s thighs as Luna planted her forelegs on her chest. Next, Celestia approached and stepped over Cadance, straddling her and rubbing her wet slit against her niece’s cock a couple times before raising her rump, lifting the pink cock until it was vertical and brushed her lips. Celestia then looked back at Bound.

“Same time?” she asked. He nodded, and she turned back, watching Luna gyrate on Cadance’s muzzle. Bound scooted back and pushed his tip down, prodding the pink pony’s entrance.

“Three… two… one…” He counted down, then shoved his cock into Cadance until his knot bumped against her, while Celestia simultaneously dropped onto her cock, fully sitting on her lap as even her sheath was inside, making Celestia’s eyes go wide and cheeks turn a deep pink as she bit her lip. He loosely hooked his forelegs over Celestia’s shoulders as he draped himself over her back, beginning to thrust as Celestia began bouncing. Bound could hear Cadance occasionally moan loudly into Luna’s pussy.

He looked up, opening his mouth to speak, but no words came out as he spotted Luna and Celestia locked in a passionate kiss, eyes closed and a foreleg wrapped around the back of each other’s heads. He smiled, and instead used his mouth to suck on the tip of Luna’s horn, feeling a tingle in his mouth as her horn sparked, and heard her moan into her sister’s mouth.

As his crotch switched to autopilot, he focused on Luna’s horn, slurping and sucking while being careful with his teeth. Mistakes do happen, however, and Luna’s horn shifted in a way that accidentally clipped a tooth. However, in a surprising turn of events, Luna eep’d and he felt a couple more sparks in his mouth.

With this new data, Bound performed a test, intentionally but very gently biting down. It was a success, as she squeaked and sparked again. He let go and bit a little harder, which produced more sparks and a moan. With this new information in mind, he began gently chewing on the tip of her horn, and listened to her squeak and gasp in a mix of surprise and pleasure as her horn sparked and popped inside his mouth, providing a pleasant tingling feeling.

Luna’s wings were rock hard at this point, alongside her sister and niece, shakily and inconsistently jerking back and forth perched atop the pink pony’s muzzle as the pink pony’s tongue was deep inside Luna’s coochie, licking everywhere it could reach, causing Luna to leak her warm thanks all over the pink pony’s muzzle. With the pleasure from the pink pony and the wolf chewing on her horn both flowing through her body, her cheeks were ablaze, ears limp against the sides of her head and eyes rolled back under her eyelids, and only barely managed to keep her lips connected with her sisters as Celestia did most of the actual smooching and exploring with her tongue, dragging it along the front and back of Luna’s top and bottom row of teeth, as Luna’s forelegs hung limp at her sides.

Celestia gently bounced on her niece’s lap, lightly sweating, while her ears drooped about halfway, although she still sported a heavy blush as well. Celestia’s forelegs were wrapped around her sister's shoulders, while one of them laid on the back of her sister’s head and gently held her sister’s muzzle against her own, lightly moaning into Luna’s mouth every so often.

After a while, Cadance began to jerk up into her aunt, while Bound’s hips began to accelerate at the same time, unintentionally biting down on Luna’s horn. The sister’s mouths also slipped apart, leaving their noses smushed together as they panted in tandem.

Eventually, Bound’s hips were a blur as they loudly plapped into Cadance, while the pink mare herself was rapidly bucking into her aunt, who had ceased her bouncing at this point. Moments later, without warning, Bound rammed his knot into Cadance, locking himself in her confines as his balls hiked up and down, his throbbing cock breaking into the pink mare's womb and filling it to the brim and beyond, inflating her belly and thoroughly impregnating her while also pushing her over the edge as well.

With a loud and long moan into Luna, making the blue mare squeak and start squirting all over her niece’s face, Cadance cock throbbed and began filling the white mare with her seed, inflating Celestia’s belly as the ivory mare drew her sister into another passionate smooch.

They rested for a while after this, all panting lightly as Celestia broke the kiss as she and her niece enjoyed the cum filling them. Eventually, Bound let go of Luna’s horn, wincing as he noticed visible cracks from his teeth.

“That can be fixed, correct?” Bound asked the blue alicorn.

“Cracks… cannot be… mended,” Luna panted. “I must chop off my… my horn from the lowest vertex of… the lowest crack and allow it to regrow.”

“If she follows that path, I will chop my horn in half as well,” Celestia stated. Cadance mumbled from under Luna, but knowing her, he inferred that she would as well.

“I… Is there no other way?” Bound asked.

“None,” Luna answered. “I can spend some… some time without magic for once.”

“Me too,” Celestia agreed.

‘Me three’, Bound guessed Cadance’s muffled words.

Bound sighed, then made a decision.

“If that is the case, then I shall stay by your side until your horns return to their full glory,” Bound stated.

“That isn’t necessary,” Celestia told him.

“I shall,” Bound told her. “If only to make myself feel that little bit better.”
