Shining Armor looked at the literal goddess lying on his bed and thought 'Yes'.

He couldn't imagine loving any other pony in the world as much as her (Except maybe his sister, but that was a totally different kind of love), and what he wanted to do right now was show her just how much he loved her. He lay down on his half of the mattress gently and stroked her along the side with a hoof. He was, after all, a gentlecolt, and wouldn't risk heading straight into his plans without making sure Cadance agreed.

His fiance turned to face him and purred, playfully flicking a hoof.

He started nibbling on her ear, while his hoof continued to stroke lower along her side. She responded with increasingly sexual moans, completely out of place and slightly comical for what was still foreplay. Shining Armor grinned, she carried the same light-hearted air everywhere, from the court to the bedroom.

He was moving to straddle her with his hoof easing in-between her thighs when the moans (which had reached near-orgasmic levels) stopped, and Cadance gently pushed at him with a hoof to force some space between them. There was a look on her face he speculated as being... worried? She'd certainly never looked like That in the bedroom before.

"What's wrong, sweety?" he broached, moving a bit more to the side to show how seriously he was taking this.

"I was thinking," Cadance began, then bit her lip. After a few awkward moments he raised an eyebrow, making her giggle.

"I was thinking maybe we could try something a bit different tonight!" she spat out at once.

Shining took a moment to consider his reply. He was a traditional stallion and not interested in anything out of the norm. But as he looked into Cadance's eyes, he realised how much this meant to her. Besides, as a princess she was certainly more traditional than him.

'Unless kinkiness increases with experience' a niggling thought complained, but another glance at Cadance's concerned face reassured him.

"Okay" He said, failing to keep his voice free of trepidation.

"Great!" she exclaimed, a nervous smile working onto her face. "I was hoping we could try it with me on top" She gushed. Shining Armor breathed out in relief- his mind had spent the last few seconds going over everything worse she might have said at this point.

"Okay, I'm ready" he said after a few more seconds spent on breathing.

"Just go along with everything I do, and I'm sure you'll enjoy it"

Cadance suddenly rolled onto him and started nibbling his neck. Hard. The combination of intense sensation and surprise made him moan in a manner that match Cadance's earlier, mock lewdness, and before he had finished recovering he felt what must have been a hind-hoof gently rubbing his balls. Just as suddenly as she had started on his neck, Cadance moved in for a kiss on the surprised stallion, her beautiful eyes staring into his. She forced her tounge into his mouth as he moaned again, and he tasted the mixture of berries they had had for dinner.

Just as suddenly as she started, she pulled back, sitting down behind his crotch, with the side effect of drawing his eyes to the formidable length held there. He had been at full mast before, but now his little soldier was Really standing to attention. She shot him a lewd but somehow reassuring grin as she lowered her head down to Celestia knows where.

'Apparently I'm really enjoying this' thought Shining Armor, or at least he would have if he hadn't been interrupted at the second word by a long lick across his taint. Cadance lifted her head up and looked into his eyes, shooting him another cheeky grin as she lowered her head again. This time she started massaging his balls again before drawing another long lick up from his plothole to his balls. Again, a cheeky grin as she looked into his eyes. As she continued this pattern he found what thoughts he could squeeze in drifting back to his earlier worries~

'How could I have worried, this,' -lick- 'feels so good, I was right to trust Cadance,' -another lick, this one slower than the others- 'of course I should trust her, she's a love goddess, if she were to suggest light,' -A couple of quick licks in succession- 'or maybe heavy bondage I'd trust her judgement,' -another lick- 'maybe even a bit of spanking or magic-play, anything for her...'

At this point Shining Armor noticed the licking had stopped and Cadance was standing over him, staring into his eyes with a look on her face that was at once serious and seductive.

"Shining Armor, do you trust me?" she spoke in an unusually serious tone.

"Completely, my love" he replied without missing a beat.

"I think you'd like dildos" she said, as her horn lit up and something under the bed moved.

It certainly wasn't what he'd expected, but he was more surprised by how okay he was with it.

That something turned out to be Cadance's 'Lonely Night' crate, and he was mildly surprised by how many exactly were in it. She levitated into his field of view a purple dildo long enough to be weaponized, and gave it a shake, sending lewd waves down its length. Shining Armor may have been willing to try a lot for his mare, but the expression on his face was still not amused.

"No?" She said innocently, before replacing it in the pile. "Well, how about... this one?" she said, now levitating a tapering replica of a griffon's dick. Briefly considering it, he decided against it and gave a slight shake of his head. A third toy briefly left the box, but he only caught the label "Giant Romantic Rubber Fist" before Cadance herself dismissed it. She looked momentarily pensive as she replaced it, before her lewd grin returned, with a slightly sinister tint.

"Okay, definitely this one, then" She said as she retreived a fourth dildo from the box, this time a fairly traditional, if slightly large, horsecock. Shining Armor had to stare at it for a moment to understand why she seemed so excited for this one, but as it hit him she leaned towards his ear and whispered conspiratorial whisper:

"Give you a taste of your own medicine"

Shining Armor paused for a few seconds as Cadance lubed up the dildo then moved it around to his behind, before speaking.

"It's not going to fit" He said plainly, in the same kind of resigned resistance typical of a colt about to enter a shoe-shop at their marefriend's behest.

"You'll stretch" Cadance replied, and after a second added "I promise it won't hurt". He found himself strangely taken by the idea of stretching, though. Maybe, one day she'd be using the giant purple one-

This train of thought was suddenly interrupted by the most intense pleasure of his life as the dildo rubbed up against his ass, and started slowly to push through. As the wide flare pushed forwards excruciatingly slowly he was surprised to notice he felt no pain, despite the intense sensation of stretching.

After a few more moments the flare pushed inside, and he felt a bizarre sensation of fullness as the next few smooth inches slipped right in, up to his own impressive medial ring. As he braced for another round of anal pleasure Cadance spoke.

"How much do you love me, Shining Armor?" She said, the serious look returning.

"I'd do anything for you" He replied with a pained look on his face.

"Really? At the moment it looks what all you want to do... is cum." She said, and his pained groan confirmed it for her. He had been 'saving up' for this night, and all the attention she had lavished on his balls had not helped things.

At this point, the dildo halfway up his plot resumed its pressure, and he felt the medial ring permanently stretching him as it pressed in.

"I bet, Shining Armor my love, that you're so willing to cum," Cadance continued "that you'd do anything I said."

At this point Shining Armor felt another source of intense pleasure, as Cadance lowered herself slowly onto his pulsing cock.

"So willing to cum," she continued with an odd intonation. Cadance, even. "That you'd try being on bottom."

"So willing to cum," she punctuated the last word with both a thrust onto his dick and the medial ring squishing into his plot "that you'd let me put your own cock up your ass."

"So-oo will-ing to cum" she repeated again, this time stuttering with her own pleasure as she lifted off his cock and pulled the dildo almost totally out of his ass. "That if I asked you'd tie yourself up and dress in mare's clothes. You'd do anything for me."

By this point, Shining Armor's balls felt full to burst, and he could acutely feel them rising.

"Cadance, I think I'm about to-"

"SO WILL-ING TO CUM!" She nearly shouted, cutting him off. The sinister lewd grin returned to her face "That you won't until I say so."

"So Willin` to cum" She spoke strangely, suddenly quiet after the last proclamation, but Shining was to preoccupied with the sensation of his swelling balls to notice the sudden accent she had put on.

"Will-in` to cum" She repeated, and his balls surged again. What was she saying?

"Will into cum" She said again, and he felt so proud for figuring it out. Maybe she'd let him cum as a reward.

"Will into cum"

His balls surged again, at this point they were the size of tennis balls.

"Will into cum"

Again his balls surged, now to baseball size.

"Will into cum"

His balls were now as thick as his hoof.

"Will into cum"

Grapefruit.

"Will into cum"

The surging feeling Shining Armor expected didn't come, though, and as he looked up at Cadance he could see she had noticed it too.

"Shining Armor, my love?" Cadance said, dismounting him and reangling her head towards his cock.

"Yes, Cadance?"

"Cum."

The command ripped through Shining Armor's system. Almost as soon as it was said his cock started to release the pressure that had been building for the last couple of hours, straight into Cadance's waiting mouth. His cock visibly bulged with the throughflow of cum, and he realised the loud, animalistic moaning he was hearing must have come from himself. Cadance was still somehow swallowing the bountiful loads, but a glance at her swollen stomach suggested she might not be able to much longer. After a couple more squirts, however, his mighty flow died down, and he stared up at the ceiling, waiting for Cadance to say something.

She was simply looking into the stallion's dull green eyes.

Author's Note

Early in this story, Chrysalis bit Shining Armor's neck and injected a venom that increases suggestibility. She also uses traditional hypno-eyes, and a bit of magic towards the end when Shining Armor's too far gone to notice.
This is my first story published ever, and while I have a lot of doubts about the quality of my writing I hope it meets everyone's expectations of a gratuitously fetishistic clopfic.
There's a second chapter in the works where Chrysalis programs Shining Armor to be a huge slut, specifically re. the chain of command (Sub for those above, dom those below), but it's not writing as easy as this first chapter did, so whether I finish it or not will depend on demand. Please comment with suggestions and corrections :P
