When Twilight told Shining Armor that she wanted to see him and his wife alone, he clearly didn't have the right idea, as the place he invited her to was the royal bedroom room instead of the dungeon. It was fine though, he would learn. She had been practicing using Cadence's magic and was confident she could give him the push he needed, it would be an ironic use of the magic to encourage violence against its very originator.

Twilight stepped into the room, dragging a box of goodies behind her, to find Cadence slumped in the bed, barely able to hold up her head even now, peering up at Twilight with a look of fear and sadness. Shining Armor was beside the bed, taking a stand between Twilight and Cadence when she entered the room. Twilight ignored his attempt to stay between them, immediately walking around to the other side of the bed.

"Twilight," said Shining, "Please tell me why you are doing this."

"Shhh brother," said Twilight, "Trust me. By the time I leave this room, you will be open to a whole new realm of pleasure."

Shining shook his head, "I'm not going to harm her!"

Cadence murmured, "Twilight please don't make it like this."

"Mmm," shrugged Twilight, "If you don't hurt her, I'm going to, and I can imagine you'd go easier on her, yes? Come on now, I love it and you'll love it, we're the same, right?"

Twilight pushed a small amount of love magic into Shining, enough to make him agree to the potential fun. It was a good thing he didn't yet know what she did to Celestia and Luna, or it would be a lot harder to ease him into things.

"I don't see how we're the sa- but fine." Shining said, then turned to Cadence, "I just don't want her to hurt you, I'm sorry Cadence."

Cadence nodded weakly and just sat there breathing heavily. She was taking the drain on her powers worse than the other two it seemed, but maybe her powers had more of an emotional component.

"Okay then," said Twilight, "Then you'll want to put this on her first."

Twilight floated a ball gag over to Shining Armor and he just looked at it cross-eyed.

"You expect me to...?" Shining asked.

"Well of course!" said Twilight "We already agreed that you're doing it to save her from me."

Shining sighed and nodded, very carefully taking the ball gag with his own magic and gently fitting it around Cadence's head. He didn't put it on very tightly, so Twilight gave the strap another tug to make sure it was snug. Next Twilight floated out a large harness that looked like it would fit over Cadence's entire form. It had a thick strap that fit around her midsection, which connected to one at the base of her tail to hold it upwards, and a collar around her neck. From the back were four straps that were apparently meant to dangle her from the ceiling.

Shining arched an eyebrow at the strange leather getup, but obediently fitted it around his wife's form. He gently turned her about as he tightened the straps, He very hesitantly attached the top of the straps to the chandelier on the bedroom ceiling, pulling them tight until she was raised up off the bed, though her legs still touched the bed itself.

Twilight had a fix for that though. First she gave Shining a set of four thigh-high socks adorned with stripes that matched Shining's mane. He actually seemed to enjoy putting these onto his partner, actually smiling a bit at how they looked on her. Afterward there were spreader bars for her front and back legs, which also folded them upwards against her body, making sure that she couldn't touch the bed and swung freely.

"Mmm, so which you like better, brother?" asked Twilight, "Cunt or ass?"

"Oh um," responded Shining, "We only do um... vaginal, she doesn't like it in--" He stopped himself and realized he probably shouldn't have said that.

"Great!" said Twilight, "Fuck her up the ass!"

Shining sighed, "I'm going to need some lubri-"

"Oh just spit on your cock if you need lube," said Twilight, "As long as you can get in, we don't want this to be pleasant remember?"

Shining gritted his teeth, clearly not wanting to at first, but Twilight's magic slowly pushed him in that direction. It didn't take long for his shaft to fall out of his sheath as he looked at his wife's behind. He nodded to Twilight, sitting up on his haunches and doubling himself over to slurp his own cock into his muzzle. He slurped against it, wettening as much of the length as he could with his spit before righting himself and moving up behind Cadence. Cadence whimpered around her gag.

"That's it," said Twilight, "Rape your wife's dry, virgin ass. Do it now."

Shining pushed his tip against Cadence's rear entry, eliciting another whimper, then grasped around her blank hips before pressing forward. She struggled, whining again, wriggling her rump back and forth against Shining as he attempted to enter. She squirming made Shining's cock throb harder, and eventually he couldn't help it. He grasped her ass firmly and rammed forward as hard as he could, pushing into the hole he had never been allowed to touch.

Cadence squealed as tears started pouring from her eyes, choking on tears as his nearly lubeless fuck spire forced its way deep into her. Her insides clenched and squeezed to try to eject him, only making him want to go deeper. He began to thrust steadily, causing the chandelier to jingle above them, pulling her back against him with each thrust as he wormed his way deeper. He gritted his teeth and moaned as he finally pushed fully inside, his balls swinging forward to smack against her pussy.

"Good," said Twilight, sitting on her haunches nearby, both hooves between her thighs as she masturbated, "Feel that unwilling ass convulse around you. The more you hurt her, the better it will feel!"

Shining groaned out louder, beginning to hammer his hips harder as his wife began to cry more loudly. He perked his ears up, surprised at how wonderful those choking sobs sounded when he was this horny. He felt himself wanting more, just as Twilight had told him he would. He rapidly sped towards his first orgasm, which hit him like a ton of bricks, causing him to cry out loudly as he pumped his juice deeply into the forbidden hole.

"Well done," Twilight ruffled Shinings head, then floated a set of piercings over to him. A pair for her breasts were adorned with tiny hearts, and one for her clit adorned with a male sex symbol made to point towards her pussy, "Next the piercing. Then after that, we really hurt her."

Shining pulled back, freeing himself from her tight ass and taking the piercings more easily than perhaps he should have. "I'm not sure how to do piercings I..."

"You'll get the hang of it," said Twilight, "And don't just pierce. Nibble at them, make sure it hurts."

Shining armor nodded, blushing at his own willingness as he leaned down to poke his face beneath his wife's behind. He held her legs with his hooves to try to steady her, then poked first one and then the other piercings through her nipples. Her cries started up again as her body jerked, her squirming starting anew and making the second piercing harder to puncture, so he poked her three times before finally getting it right.

He did as Twilight had asked, nibbling on each nipple afterward, even pulling at the fresh piercings in his teeth, then biting hard on the nipple itself and pulling them to see how far they'd stretch. It was enough to make her scream around her gag. He only stopped to pull his head up to see the third jewel. He waited for her to grow still and then shoved it through her clit, making her writhing start anew. Not getting it right on the first time, he pulled it back out and then turned it around, pushing it back in so that the sex symbol faced correctly.

Shining pulled his head back, sitting on his haunches for a moment and watching his wife suffer. She squirmed and whined back at him, and he could tell she wanted to be held and comforted at the very least, but something made him not do so. He was starting to see how fun it was to make someone suffer.

"Now in her cunt," Twilight ordered casually.

"But she likes it in the cunt," Shining nodded all the same, pulling himself up behind her again. His shaft was rock hard again, throbbing impatiently from her reactions.

"Oh I'll make it hurt," said Twilight, "I just want you to feel her clench when I do this."

Twilight pulled out a brand from her box, much like the one she had branded Celestia and Luna with, but with Shining Armor's cutie mark. She began to heat it up with her magic, patiently waiting for it to get hot. Shining's eyes got big as he realized what was going to happen, but didn't complain as he might have before. He just nodded again, licking his lips as he pulled himself close to his wife, pushing his drooling tip against her entrance and easily sinking ball deep on the first thrust, cock enveloped in her heat. She grunted at this, but then saw the brand and began squirming once again. Shining did his best to hold her still as he started to thrust slowly.

As Twilight brought the brand closer, she suddenly felt Shining's magic try to take it. At first she thought he was going to try and prevent her, but instead he continued towards her.

"You said I could do it," said Shining, grinning playfully to his sis.

Twilight grinned back. Her magic was working better than she imagined it would. "As you say." She released it, sitting back to watch, and masturbate obviously.

Shining did hesitate, or perhaps he was just letting her feel the heat on her flank, which made her scream in anticipation, drooling around her ball gag. When he finally touched her flesh, her screaming went up an octave. Shining moaned loudly, both at the sound of his wife's sobs and the feel of her rape hole clenching down suddenly and convulsing in agony around his shaft. He sped up his motions and pressed the brand harder to her flank, not pulling it away until her flesh was boiled and bleeding.

Shining began to reheat the brand with his own magic as he brought it around to her other side. Pressing it into her flank, he started thrusting faster to fully appreciate the tight spasms around his shaft. Twilight continued to pressure him with her magic even then, watching him roll his eyes back and drool out the corner of his muzzle, savoring Cadence's pain.

"That's it you slut," said Shining, "I think we're going to go in a different direction with this marriage."

Shining came even harder than he had in her ass, ramming his cum deep inside. He hosed her insides down for almost a full minute, her belly bulging and excess drooling out from around his insertion. He arched his back and screamed in utter bliss, body shaking even more than Cadence's.

He didn't even break his stride, continuing to thrust into his sobbing slave's fuck gate. When Twilight pulled the enchanted hacksaw out of the box and tapped it against Cadence's horn, Shining took it without hesitation, actually grinning even wider at the chance to cause Cadence even more intense agony. Slipping his hooves to grip Cadence's behind on her branded flanks, he continued to thrust as he pushed the saw to the base of his fuck toy's horn.

Cadence screamed anew, desperately trying to turn her head this way or that. Shining by himself wouldn't have been able to hold her still, so Twilight helped by holding her head tightly in her magic. Shining began to saw without hesitation.

"That's it," said Shining, "We're gonna cut this bitch's horn off. Hear that, love whore? You'll be my little hornless cum bag."

Shining seemed to get more excited the further he got, body shaking and sweating profusely. Twilight actually dialed back the magic she was pouring into him, as he was in no danger of stopping. Cadence's weeping was wonderful, a mix of pain and betrayal as her loving husband turned into an abusive monster. So much for her happily ever after.

As her horn snapped off with a loud pop and a small burst of magical energy, Shining came again into her already cum drenched passage, overfilling her again, his rape juice flooding down both of their thighs and drenching his balls, puddling on the bed. Shining groaned as his thrusting finally slowed, panting heavily and leaning against Cadence as she continued to cry. He grasped the horn with his magic, pulling it back to where he was and then pushing it tip first into Cadence's cunt.

"You grip that tight, pegaslut," Shining said to Cadence, "Or I'll make it hurt." He then said to Twilight as if nothing was amiss, "Can I keep this stuff Twily?"

"Of course!" said Twilight, "I think you should keep the horn too, as a trophy!"

Shining smirked, "Oh I intend to and... thanks Twily. I'm glad you um... showed me what I was made of."

"Oh I'll be back here every few days for a while to make sure you're coping," said Twilight, she wanted to make sure he was properly deranged before the magic wore off, "I got to take my leave though, I have some hornless sluts of my own to care for."

"Sure thing," said Shining, "I'm not done with Cadence either, we'll be playing long into the night."

Twilight smirked, "Good to hear. I'll see you at the celebration!"
