Sibling Revelry

Shining Armor had help with his purchases. It turns out Cadance was really into the idea of her husband in panties. She took him to the local clothier to find him some lingerie.

"So, the first thing you'll need is a cotton set. You're going to need that to sleep in. The lacy set is only for special occasions. Oh, and a nice, feathery nightie made from a smooth mesh, so we can see right through it."

"I'm glad you're so excited, Cadance, but you should calm down a bit," said Shining Armor, shushing her with his hands. "We don't want the whole empire hearing about this."

"Oh, they won't mind, Shiny," reassured Cadance. "More than half the guards know how you like to be bedded, and it's only encouraged them to do better to gain your favour."

"Well, yeah, but..."

"Besides, it says nothing about your ability to govern them. You've been doing good so far, right?" Shining Armor nodded. "Then there should be no problem, should there?"

"I guess not." The carriage pulled up to the shop and the two stepped out onto the street. As Shining Armor looked up at the sign, he was very confused. "This isn't a clothing store."

The store they entered was not a clothing store, though it did sell clothing. It was an adult toy shop, and one of their best selling items was a pair of vibrating panties. While Cadance was certainly planning to purchase a set for her husband, she had other things she would have to buy first.

"How may I assist-- Princess Cadance!" The clerk leaped from behind the desk and ran up to one of his most frequent customers. "Wonderful to see you again. How did you enjoy your werewolf friend?"

"Werewolf?" asked Shining Armor, thoroughly lost. "What werewolf?"

"I'll show you when we return to the palace, dearest," chuckled Cadance. "I enjoyed it quite a bit. That knot was a bit of a struggle, but I managed eventually."

"Glad to hear it," smiled the clerk. "What are you looking for today?"

"Well, as you can see, I've brought my husband along."

"You're a lucky stallion, sir," chuckled the clerk, vigorously shaking Shining's hand.

Cadance's face twisted into a slightly sinister smirk. "We'd like to have him outfitted with a few basic pieces of gear. I was thinking we start off with a vibrating plug and a cage."

"Cage?"

The clerk smiled. "He's finally accepted it, huh?"

"Accepted what?"

"A nice, wide ring gag, too," added Cadance. "I want him to still be able to take one of the guards from the front end while keeping silent."

"Don't I have a say in this?"

"Of course, Princess," replied the clerk, grabbing Shining Armor by the wrist. "I'll have him fitted right away. You can even walk him out of here wearing his new equipment. Would you like a collar and leash, too?"

"I very much would, thank you." She waved to her husband as he was being escorted away by the clerk. "Bye, Shiny. I'll see you in half an hour."

The clerk escorted Shining Armor to a small room in the back and sat him down on a bench. "Alright, take off your pants and let's see what size you are."

Shining Armor was quite confused by the whirlwind he had just been through. Not knowing exactly how he had made it this far in, he had no idea how he would make it out. He reasoned that the best solution would be to just accept what was going to happen to him. Clearly, Cadance trusted this clerk, so he must know what he was doing.

With Shiny's pants sitting on the floor, the clerk frowned and shook his head. "I know those are cute panties, but they're too small for you. You'd look much better with something in your size, and it would be much more comfortable. Take them off, too."

Shiny did as he was told. "Even if they're the wrong size, I want to keep them. They're special to me."

"I completely understand, sir, but look at those marks on your hips. Those come from wearing clothing that's too small. Think for a second about how your boyfriend would feel. You take him to your bed, he removes your skirt, takes off your panties, and is met with those marks. It's a pair of phantom panties that he can't take off to admire your magnificent buttocks."

Shining blushed. Thinking about being fucked by a stallion had given him the beginnings of an erection.

"We'll have to take care of that, too," smiled the clerk. "You're to be fitted with a cage, and I think I have just the right one." He moved to the back of the room and shifted several boxes aside before pulling out a wireframe chastity cage complete with lock. "You're a big boy. And big boys need big cages."

After thoroughly washing his hands and putting on a pair of gloves, the clerk grabbed Shining Armor's semi-firm cock in one hand and a small ice pack in the other, rubbing them together. "We need the swelling to go down as much as possible," explained the clerk. "Otherwise, you won't fit in the cage."

"What's the point of the cage again?" asked Shining Armor, shifting uncomfortably as his dick was being frozen.

With it now being small enough to fit, the clerk slid the cage up Shining Armor's shaft, locking it tightly around his testicles so that it couldn't be removed without the key. "It stops you from having an erection," replied the clerk. "Eventually, when the keyholder decides to let you go, that first load will be a huge relief. Trust me, it'll be like nothing you've ever felt before."

With the cage now in place, Shining Armor looked down at his cock. A vision of Twilight riding it flashed through his mind, prompting another erection, but all he managed was to tighten the cage uncomfortably around him. "So, how long do I have to wear this cage?"

"Until Cadance releases you, of course. She'll be walking out of here with the key, so if you want it off, you'll have to discuss it with her."

Shining looked down at Twilight's panties on the floor. In two weeks, he would be with his sister again. Would Cadance then allow him to take the cage off?
