“You did what, darling?” Rarity’s voice was a scandalized.

“I… well…”

“Fluttershy, you know what kind of ponies they are!” Pinkie chimed in.

“Well yes, but…”

“Really, darling, you clearly were influenced by your lower thought processes,” Rarity continued.

“Maybe, however…”

“You know you should never shop while horny!” Pinkie agreed.

“Be that as it may…”

“Clearly you’re not responsible enough to take care of yourself,” Rarity’s words ran right over her.

“I…what?”

“Right. Clearly,” Pinkie giggled. “A cute mare…er…I mean an irresponsible filly like you needs ponies with a firm hoof to keep you from making these sorts of foolish decisions.”

The three of them sat in one of the many empty rooms in Twilight’s castle. It was far enough away from the public areas, like the throne room and the library, that they were unlikely to have unexpected visitors.

The room was simple, with a small table, four elegant chairs, and a single crate that had been delivered just yesterday. Stenciling on the crate labeled it as a product from ‘Flim and Flam Industries’.

“Are you just making another excuse to ‘punish’ me?” Fluttershy asked, eyes narrowing. “Because you don’t need an excuse, you can just ask.”

She squirmed a little in her chair.

“Besides, I ordered it weeks ago, and I had no idea it was a Flim and Flam product. It was a mail-order catalog that Twilight found for me. Black Box Adult Supply, I think it was called. I don’t know if it’s a subsidiary company, or if the brothers bought it out.”

“Darn,” Pinkie said. “I was really looking forward to punishing you for foolish purchases.”

“Not so fast, Pinkie. Fluttershy darling hasn’t even told us what it is.”

“Um…” Fluttershy fiddled with her hooves, rubbing one against the other. “It was called the ‘Mare Breaker 4000. It’s…uh…a fucking machine.”

“Fluttershy,” Pinkie said disapprovingly. “I’m sure it’s a bad machine, if those two made it, but you don’t need to call it a—”

“She means it is a machine that fucks, Pinkie,” Rarity clarified, and Pinkie let out a slow ‘oooooh’. “A contraption where the pony in question is often restrained and then pleasured by mechanical means.”

“Sounds like you have experience,” Pinkie said to Rarity, wiggling her eyebrows. Rarity blushed prettily and looked away.

“I was hoping that the two of you could help me put it together,” Fluttershy said. “Pinkie, you have a real mind for technical assembly, with all the contraptions you put together. And Rarity, you’ve refined your telekinesis for fine detail. Twilight wanted to help, but she’s tied up in diplomatic meetings in Griffonstone.”

She’d be pretty pent up when she got back, Fluttershy noted with a secret grin.

“We’d be delighted, darling. And should you need to do a quality control check, I think we may be willing…”

The Mare Breaker 4000 wasn’t all that hard to put together, though there were a few missing screws. Fortunately Pinkie happened to have the exact matches tucked away in her mane.

The contraption was a narrow padded shelf to rest on, shaped like an upside-down ‘V’, like a sawhorse. The legs of the sawhorse were complete with built-in cuffs. Behind the ‘V’, was an electric motor housed in a sleek pink case. Extending from the motor was two mechanical arms, each one ending in a detachable pink dildo. The higher of the two arms had a smaller phallus. The crate had come with a catalog of optional attachments that could be ordered, if Fluttershy wanted to experience more ‘exotic’ partners.

She already had her eyes on ‘dragon’ and ‘kirin’. She hadn’t known that the kirin manes meant they were related to cats.

But for now, she was ready to get strapped down.

“Now are we sure about this?” Rarity said. “Setup was easy enough, but it is a Flim/Flam product…”

“It looks structurally sound,” Pinkie said, sounding doubtful nonetheless. “But we’ll still need to stress test it.”

Fluttershy did eye the anal dildo with some apprehension. She hadn’t yet felt comfortable enough for the full penetrative experience there, but she had tried a few small toys. This one wasn’t much larger than the butt plug she’d worn a few days ago.

“Um, should I go first?”

“It is your toy, darling,” Rarity said, and PInkie nodded, grinning. “As long as you don’t mind us watching.”

“Isn’t it funny,” Pinkie said musingly, “that a few weeks ago, if one of us had said, ‘hey, can we watch and probably make out and have sex while you tie yourself to a mechanical humping machine so you can get bucked silly?’ the rest of us would have called you crazy and given you funny looks and maybe a recommendation for a therapist.”

Fluttershy giggled. She’d been thinking the same thing.

“I believe that’s part of what Fluttershy intended,” Rarity said. “An erosion of the barriers between us. Tell me, darling. What is your end goal here?”

Fluttershy smiled shyly. “We’re getting closer,” she admitted mysteriously, but said nothing more. Rarity and PInkie stared at her until she blushed. “W-well, can you help get me strapped in?”

“But you didn’t—”

“Rarity, she’s clearly preparing some kind of surprise party,” PInkie said. “Don’t badger her! C’mon, it’s time for today’s game.”

“Well, if you—”

“Rarity! No spoiling the surprise!” PInkie demanded. “Flitter on up, Fluttershy. We’ll get you strapped in.”

It was easy enough to sort out. Fluttershy flapped her wings and landed, hindhooves spread, on top of the sawhorse. It was comfortable on her barrel, and her friends quickly strapped down all four hooves on the legs of the device.

“Oooh, and her tail’s already nice and flagged.” Pinkie leaned in close, her nose nearly in Fluttershy’s slit. “Nice and wet, too. We almost don’t need lube!”

She giggled, and Fluttershy blushed.

“But Pinkie, darling, if we skipped the lube then we wouldn’t get the fun of applying it,” Rarity cooed, approaching with a bottle of lube floating in her magic. Fluttershy looked over her shoulder at Rarity’s wicked grin. Pinkie giggled, and Rarity squirted a liberal amount on her hoof, and then on Pinkie’s. “Do you want the top hole, or the bottom?”

“Hmm… I’ll take Fluttershy’s tasty slit… and then your backdoor, Rarity.”

Rarity laughed as she reached out with her lube-soaked hoof and began to massage Fluttershy’s tailhole. PInkie did the same for her marehood, and Fluttershy squirmed and whimpered.

When she was plenty lubed, Rarity insisted on doing the same for the toy’s phalluses, and she and Pinkie devolved into a fit of giggles as the two of them made a show of fellating lube onto the silicone ends.

Finally everything was ready. Rarity adjusted the machine so that the slick tips were just brushing Fluttershy’s entrances. She tried to wiggle back, to push them in just a little more, but her bonds held tight.

“Okay, time to turn it on. You ready?” Pinkie asked.

“Yes. Please,” Fluttershy said impatiently, and Pinkie smirked, flicking the switch on the motor.

There was a hiss of sparks, and the lights in the room went off.

“I found it!” PInkie said, laying back on the rolling mechanic’s rest she’d produced from…somewhere. She also wore an oil-stained blue coverall, just as mysteriously sourced as the rolling rest and the ratchet set she’d used in her mechanical inspection. “There’s a short in the electronics here. When I turned it on it overloaded and sent off a magic pulse that interfered with the lights here.”

“Can you fix it?” Fluttershy asked desperately. She was getting hornier with the wait, and it made her impatient.

“I don’t have the parts on hoof,” Pinkie admitted. “I’ll have to send out for ‘em. I can jury-rig a solution for now, but you’re really gonna want to get the right stuff in as soon as possible. I’m thinkin’ five to seven business days.”

“But we can fix it just enough to run for now, right?” Rarity said, just as eager as Fluttershy, it seemed.

“Yup,” Pinkie said, and pulled herself out from under the motor. “I got ‘er set up for ya. Flick that switch and we can get goin’.”

For some reason she was starting to drawl like Applejack. But Fluttershy couldn’t think about that for now, she was so needy.

“Well, if you think it’s okay…” Rarity said, and once again flicked the switch. For a moment the motor rattled to life, and the first of toys began to thrust. Fluttershy let out a moan as the toy sunk into her cunt, one inch…

There was a loud crack, and the pressure on her slit disappeared as the mechanical arm fell to the ground.

“What now?” Rarity cried out in desperation, flicking the machine off.

“Huh,” Rarity said after a thorough inspection. “Every single screw that came with the product is flimsy. Every single one of them is a disaster waiting to happen. Pinkie, you still have a few left over in your mane, right?”

“A few,” Pinkie said. “But if every screw is bad, we’ll have to replace every single one?”

“I’m afraid so,” Rarity replied. “If nothing else, this contraption simply isn’t safe. Come on, Fluttershy darling. Let’s get you untied.”

Fluttershy groaned.

It took them another hour to replace every single screw. Three more of the screws that came with the product broke while they were in process. By the time they were done, all three of them were cranky and needy.

Finally they were able to get Fluttershy back in place, ready to turn it on again.

“Keep your hooves crossed,” Pinkie muttered. “And good—”

“Don’t even jinx us, darling,” Rarity groaned. “Let’s just get this over with.”

She flicked the switch.

Nothing.

All three of them groaned.

“I didn’t even know that spell batteries had an expiration date,” Rarity’s voice was exasperated. “And why would they send out merchandise with expired components? It’s just bad business practice.”

“I think,” Pinkie said, as she installed the new battery they’d found in Twilight’s storage room, “that’s part of the point of their business model. Flim and Flam keep costs low to maximize margins, then rely on new customers taken in by flashy advertising and fast-talking sales presentations. They don’t bother to keep old customers as long as they can keep bringing in fresh blood.”

“That’s a pretty astute analysis of their business model,” Rarity said. “But I thought they’d improved after they took over that resort in Las Pegasus.”

“But remember, that was before their Friendship University,” Pinkie continued.

“Can we please focus?” Fluttershy groaned. “I just want to get started.”

“Okay, okay,” Pinkie said, fitting the battery cover back in place. “That should be enough. Let’s just turn it on to see if it works, then we can worry about getting you in your spot.”

“Right,” Rarity said grimly, and her horn lit as she flicked the switch.

Everything went white. Sparks and smoke filled the room. The air was full of the smell of ozone and fried electronics. PInkie screamed, and Fluttershy dove in front of her, wings spread protectively. Rarity covered all three of them in a bubble of magic, just in time for half-melted plastic, broken glass, and silicone misshapen from the heat to rain all over the room.

“For Celestia’s sake!” Rarity growled, as the hissing and smoking died down. “Darling, I don’t know if we can fix this.”

“Oh, I think we can,” Fluttershy muttered, stepping towards the melted pile of electronics, mechanical gears, and plastic. “Pinkie, open the window.”

With a nervous look, Pinkie did so. Fluttershy scooped the entire thing up and, with a howl of rage, she hurled it all out the window.

Pinkie and Rarity stared at her.

“There. I fixed it,” she said, turning back towards them after making sure the debris hadn’t hit anypony. “Now. I’m angry and I’m horny. I can either go take a cold shower, or we can figure out if there’s anything in this room that’ll rut me silly that isn’t breakable.”

Rarity and Pinkie Pie gave each other a look.

“I’m scare-roused,” Pinkie whimpered meekly, and Rarity nodded with a gulp.

In the morning, Ditzy Doo the mailmare found the three of them cuddled up in a pile of torn blankets and destroyed pillows. Fluttershy was fast asleep, though the other two were just waking.

“I have a ticket for Miss Fluttershy. Fifty bit fine for littering…” Ditzy began, but Rarity held a hoof over her muzzle.

“Shh,” Pinkie whispered. “She had a rough time yesterday. I’ll take that for her. Thank you.”

“You should move on, darling,” Rarity said with a smile. “I don’t know how she’ll be when she wakes up, but she was pretty upset. It took both of us to calm her down.”

Ditzy sniffed the air, clearly noting the scent of sex on the air, and gave a little giggle.

“Okay. Um.”

Ditzy had always admired the beautiful, graceful Fluttershy, though…

“Maybe I should stick around, though. In case the littering ticket makes her more upset, and she needs to calm down again.”

She tried to give them a half-lidded look. It seemed to work, because the two of them laughed.

“Maybe you should,” Pinkie cooed. “Come, pull up a… scrap of blanket. We’ll see how she feels when she wakes up.”

Author's Note

Okay, maybe this chapter went a little closer to silly than sexy. But the idea was too good to pass up.
