Disposing of the Evidence

As Twilight set down her fork, she picked up her chased goblet and aerated her drink. "Your hospitality is something I look forward to every time I come up here," she smiled, a twinkle in her eye. She took a swallow of her drink. "Your food is pretty good, too."

"You're always welcome here, Twilight," chuckled Cadance, finishing her cake. "Every time you come up, Shiny's mood improves dramatically. I mean, it's no wonder, right? He loves his favourite sister about as much as I do."

Twilight let out her own giddy chuckle, which soon turned into a hint of worry. "Do you think we've kept him waiting too long? I mean, I'm all for building up the excitement, but it's been almost half an hour, and I've read that it feels even longer to the one tied up."

"Oh, he's fine, Twilight," assured Cadance, waving her hoof dismissively. "I once kept him waiting for over an hour because something came up. He was fit to burst, but he handled it like a champ. A short little half-hour like this, he should be up and ready, but still have some stamina left."

"As long as you're sure," nodded Twilight. "I just don't want to hurt him, that's all."

"Do you want to go see him now?" offered Cadance with a smile. "While he can wait a bit longer, there's nothing wrong with popping in a little early to see how he's doing."

With a nod, Twilight stood up. "I think I'm ready to see him now. I don't want to wait anymore."

The two walked back to Twilight's room, a large bedroom just off to the side of where Cadance and Shining slept. Despite Cadance's well-known debauchery and openness in her sexuality, Twilight didn't want the whole of Equestria to know what they were all doing behind closed doors. They were allowed to know that she supported family values, and that she led by example; coming to see her brother and sister-in-law at least every few months. She had no qualms against that being public knowledge.

As they arrived, Cadance gave her a hug, and they retired to their separate rooms. Unbeknownst to the general public, the two rooms had a secret door connecting them, hidden behind the Cadance de Milo painting on the wall. As Twilight was stripping down, the door swung open and Cadance walked through.

"You remembered to bring lube this time, right?"

"I made a checklist on edible paper with edible ink this time," smiled Twilight, quite proud of herself. "I brought strawberry kiwi and peanut butter banana. I want to compare the differences between them, if we have time."

"If we have time," agreed Cadance, opening Twilight's bag and shifting all of the clothing aside. As she reached the bottom compartment, she laughed. "Did you bring enough dildos? I can usually be taken care of by one or two, but you have what, eight?"

"There's only eight!?" gasped Twilight, rushing forward and rifling through the bag. She dumped out all of her toys and counted up her dildos. She breathed a sigh of relief as she found all nine of them. "Don't scare me like that, Cadance. I thought I'd dropped one somewhere. Do you know what would happen if someone found one of my strap-ons just laying around?"

"They'd think it was just a random dildo and throw it out, then wash their hands," answered Cadance. "Just like they do when they find mine. It's a waste of silicone, I'll admit, but at least they're not using them. That's why I told you not to put your name on them. You don't want some weirdo using it then giving it back, do you?"

Twilight shivered at the thought. "The reason I brought so many is because I wanted to try some of the new ones."

Cadance picked the new ones up. "The dog and dragon? Twilight, it doesn't matter what dick you have, he'll love having it in his arse, because he loves you. There's no need to impress him with fancy toys. Just push right on in and he'll be putty in your hands."

"Hopefully, he won't be that soft," joked Twilight.

As they laughed, they stepped back into the royal bedchamber. Shining Armor was tied to a chair, buck naked save for a bag over his head. His little soldier was standing at full attention, and firing off little drips of anticipation. He couldn't hear or see them, but his nose was very excitable. He followed the scent of Twilight as she moved around him, aggressively taking in her perfume.

"He's certainly excited to begin," chuckled Twilight, slipping into her straps. "I bet he can't wait."

"He's been talking about it all weekend," smiled Cadance, taking a spot behind her husband. "He really does love you very dearly."

With her tackle secure, Twilight kneeled in front of her brother. "I love him, too." In evidence of her statement, she placed her tongue at the base of his salty balls and dragged it along the underside of his turgid cock. By the time she reached the tip, he was ready to fire a great load into her open mouth. She savored the taste, swishing it back and forth in her cheeks before standing up and letting it drip into his open mouth. What stuck to her tongue was quickly gobbled up by Cadance as she undid the bindings.

As soon as he could use his arms again, he squirted some lube into his mouth, using it to apply a slick coating to both of Twilight's strap-ons. One was in the usual place around her hips, but a second one was up around her waist. That was a very odd configuration, and seemed to be custom-made. He didn't know what it was for, but he was willing to see where it was going.

As he finished up, Cadance grabbed him by the shoulders, pulling him over to the bed and up on top of her. As she kissed him, she used her hands to direct him into her vagina. There was never a need for lubrication with her; she was always wet. While what he wanted was Twilight, his wife was always a satisfying choice, and he began to thrust until she held his hips still.

Suddenly, he felt something big and firm pressing at his backside, He also felt Cadance tighten around him, as if somepony had shoved a cock up her arse. With a smile, he realized what the odd strap-on was for, and he relaxed his anal sphincter as Twilight pumped into both of their arses, filling them with glee and silicone.
