A Charmed Night.

“Hey Cadance, we just got a package from Twili.”

Princess Cadance, ruler of the Crystal Empire, looked over to her husband, Shining Armor, who entered the throne room with a package.

Shining was a well built testament of manhood. He effortless towered over his wife and rippled with muscles. She loved how big and manly he was. Many were the times she had tingled as he swept her into his arms and…

She broke off her thoughts before they got her too worked up to continue her duties.

“Well? Are you going to open it dear?”

Shining came to stop beside her looked down at his wife. For a princess, Cadance was on the small side. She didn’t even clear his broad shoulders and while he loved her slender, petite body, there were times he wished she was bigger like her fellow princesses Luna and Celestia.

“I don’t know.” Shining held it at a distance. “Twili has a bad habit of wanting to explore and experiment with magic stuff she doesn’t understand. What if it does something weird?”

Cadance giggled at this and took the package out of his hands.

“Dear heart, you can be ridiculous sometimes.” She opened the package and saw that her sister-in-law had sent them a strange pair of zebra shaped earrings and a letter. She read it out loud.

“Dear Cadance, I discovered this magical trinket at the market and didn’t have any clue what it does.” She stopped reading and looked up to her husband. Shining Armor's mouth was quirked into a smug ‘I told you so’ smile. “Not a word, Shining.” She grumbled up at him. He lifted his hands up in surrender, but that smug smile only grew wider. Scowling, Cadance returned to reading the letter aloud, “I thought you might be able to figure the spell out as enchantments like this one are a specialty of yours, love your sister-in-law Twilight.”

Her attention moved to the amulet. Delicately, she fingered it, sensing the immense power residing within. She reached out probing it with her magic and as she did this, felt the amulet respond with an immense magical wave that filled her.

Dropping the amulet, she clutched at her chest. It felt tight. Her body felt as if a slow massage was suffusing every inch. She gasped and her hands fell to her crotch, which was on fire. But where there should be her feminine slit instead there was a fleshy, protruding shaft! Her hands pawed at the bulge and she groaned at how pleasant the contact made her feel.

“What’s happening!” She cried out in distress then to winced. Her voice sounded so coarse and deep. With great will, she forced her hands to leave the incredible pleasure of touching her new appendage and explored her changing body. Her hips, thighs, and buttocks were slimming and tightening. Trading fleshy hills of feminine fat for bulky, male muscles. Her tummy was no long soft but was instead sporting a cobblestone of six visible abdominal muscles. Her breasts! Those beautiful signs of her femininity which her husband had loved to palm and play with were disappearing to become flat pectorals.

As she lifted her arms higher, she heard a loud tear. *RIIIIIIP*. Looking over, her eyes shot wide. She had muscles. Big ones. Her arm had flexed and torn her shirt sleeve. It was shredded and reminded her of Shining’s nice, big arms that he held her in. She experimentally flexed and watched in mixed awe and horror as the bicep flared up, then rather than staying the same size, flared even bigger with every subsequent flex.

“By Celestia!”

Cadance turned her attention away from her new form and saw with horror a beautiful vision of femininity where Shining Armor had been seconds before…

The woman standing there in Shining’s clothes was roughly the same height as her. She was groping at the two large breasts on her chest. They were perfectly round and pink, each sporting a prominent areola and nipple. “Shining, dear, is that you?” Her husband looked up from his breasts to her. “Ca-Cadance? I, yes its me. What’s happening?”

He looked over at her and saw the very prominent bulge under her dress, and turned his head away blushing cutely.

Cadance self consciously reached down to her new equipment. “I don’t know,” she began. She looked around the room. “Judging by my position and the size of the objects in the room around us, I don’t think I’ve grown taller. I’d say the amulet is changing our bodies and,” she groaned a little, precum staining her shorts, “I think it is goosing our libidos up quite a bit.”

Cadance, after her initial freakout, wasn’t minding the situation as much. Sure, she preferred her normal body. But this was likely some kind of ritual zebra spell, a cultural touchstone designed, if she was not mistaken, to enable partners to better know each others bodies. She could, of course, undo it after a little research. Moreover, it would be a waste not to explore it and learn from the new sensations it was giving her and Shining Armor. Yes, best to follow through on the desires it was causing her to have.

The only problem left was convince Shining to play along…

That was it. Role play. Maybe that was the key to getting him to loosen up and go with the magic flow. “Oh my, Gleaming.” She moved over to her husband. He was now roughly the same height as she was. He looked up from his bewildered exploration of his body only to see her hungrily eyeing his new breasts. “G-gleaming?” Cadance wasn’t paying too much attention to his words. Somehow, despite never really being attracted to women, she found looking at her husband’s growing, womanly body was fueling her already fiery arousal. “Wow, you're bigger than I was, hmm,” she reached out and grabbed, somewhat roughly, her husband's big tits. “Ooooh, Ca-dance.” He squealed and experienced, for the first time, the female orgasm.
