Chrysalis carefully licked the last of the will-cum-cum from Shining Armor's cockhead before sitting up. She looked down at the hypnotised stallion, allowing herself the narcisistic thought of how much prettier his eyes looked in her magic's colour. She loved this next part best of all, so much better than having to get the stallion off- the part where she made him hers. Oh, how she couldn't wait to rub it in the face of that Cadance bitch- her own immortal patience had been tested by how the alicorn had spent the first hour demanding in some magically-enhanced voice that her conditions be improved right this second. While it gave Chrysalis some nice clues to her personality the damn shouts had been so loud her ears had been left ringing, and her changelings had to capture several ponies ahead of time who had heard the fuss and investigated, forcing her to put her plans into high gear before the dissapearances were noticed. Not that it mattered anymore, with the living beacon Canterlot's defence was built around under her sway, she was sure the coming day was going to be just perfect.

She stood up off the bed, and trotted over to where the stallion's head was laying limply, noticing that she was standing a bit too tall en route.

'Oh dear, my disguise broke at some point there. At least he's too far out to notice...'

With a flash of green flame she re-applied her disguise and lowered her head to his ear.

"Shining Armor," she started, and the effect on him was immediate, if subtle. His unfocused eyes swiftly turned to look at her. Limp, open jaw and immobile head remained as they were, however.

"I'm going to give you some commands now, and you are to follow them to the best of your ability. Say 'Yes' if you understand." She continued.

"Yaaarrrh" was Shining Armor's reply, a mix between the instructed reply and a moan that came out sounding a bit pirate-esque.

"Okay, nod if you understand" Chrysalis corrected. She did love having that effect on ponies. Shining Armor enthusiastically nodded, head bobbing asychroniously with his limp jaw.

"If, at any point, some... pony,"(She shuddered at the race-exclusive pronoun) "If some-pony seriously suspects that your behaviour has changed, or if somepony suspects me, you will stop obeying these commands until the suspicion stops. You will, however, agree with everything I say regardless of whether or not somepony is suspicious. Nod again, and after every further command if you understand."

Another enthusiastic nod.

"And shut your mouth when you're hypnotised. You'll catch parasprites."

That should cover her ass if somepony close to Shining Armor noticed anything funny, not that she planned to let him invite any such ponies to the wedding. Innevitably, his parents would end up coming, but hopefully she could keep his sister in whatever backwater burg she was in. If half the rumors were true...

"Ok, whenever I, and only I, say the word 'headaches' you will return to your current state of mind," She paused, waiting for him to nod, before continuing. "And if I say "Feeling Better?" You will wake from this state and return to regular consciousness." Again, nodding.

Excellent. She had him now and forever; she doubted even the princesses could remove these commands from the stallion without her. Now though, it was time to make him hers. The more rational half of her was shouting to hold back, that anything more would just increase the chance of her plan being found out, but her more emotional side calmly asassinated that train of thought with imagine fucking him in front of Cadance, literally dominating her life in front of her.

'That should get under the bitch's skin'

"From now on, whenever you're thinking of sex with..." She almost said 'me', before deciding a blanket term of 'royalty' would be better suited if her disguise slipped again.

"Whenever you're thinking of sex with royalty you will automatically act submissive. You don't have any choice in the matter, you just know the only way to treat your betters is to let them decide how to use you." Frankly, Chrysalis found the idea of having some stallion leading her in the act disgusting, and she was very glad she'd managed to 'convince' him to switch early in their session.

Yes, leading the stallion around by his cock was sure to get under the bitch's skin, but it wasn't enough. For all she knew the goddess might think he was doing it out of love for her. No, she needed Shining Armor to do something for her he'd never do for Cadance... Hmmm...

A glance around the royal lover's suite lent itself surprisingly well to inspiration, as she noticed 'her' dresser hanging open.

"You love dressing like a mare in heat. You can't help loving the idea of looking so sensual and seductive, and the fact you're a stallion doesn't get in your way." Chrysalis paused as she realised he couldn't go around in the day like this, though, idly noting the stallion's nod. Unless...

"The only thing you like more than wearing mare's clothing is wearing mare's clothing in public, with nopony else noticing. You wear it under armor, under suits. If you are so much as wearing boots you put on feminine socks under them."

She could picture it now.

'She leads Shining Armor into the cave, making sure to stand infront of that translucent crystal pane so she sees. He doesn't notice her as he slowly removes his guard armor, revealing Cadance's own clothes underneath, clearly loving every minute of it. He rolls onto his back, and she fucks the shit out of him. I hope she screams for him as he cums. She's probably so used to being the center of attention just having him not notice her would ruin her'

She was mid-turn towards retrieving some clothes from the dresser for him to start with when her hoof stepped in something wet. Bringin it to her noise she realised it was an all-too familiar scent.

'Heh, guess taking Equestria's best and brightest and making them my personal sluts is turn on of mine.' she noted with genuine surprise. Now that she thought back though, she had been getting really into that revenge fantasy. She briefly imagined what she might end up doing with Cadance after the invasion before her mind wandered up to the next step.

'Princesses Celestia and Luna, grovelling love-sluts...' She noted with a touch of surprise that the thought actually made her weak-knee'd; she never felt so strongly about any fantasy before. She briefly considered hoofing herself off before the more obvious alternative sprung to mind.

"Oh, shinee... feeling better?"

The beautiful green glow faded from the Stallion's eyes and his relaxed position quickly transformed to a more alert one.

"Yes, my princess?" His reply was tinted with subtle hints of submission that hadn't been there before, not least calling her 'Princess' instead of 'Cadance'. She should change that to 'Master'.

"I find myself in need of 'servicing', do be a good colt and get your princess off, would you?" She said, laying down at the foot of the bed with her flank hanging off the edge.

Shining Armor apparently hadn't needed the whole sentence, he must've stood up around 'service' for how quickly he got his tounge in her cunt. He was masterful at this, his tounge expertly picking out her more sensitive spots, while still giving her clit a good licking too. Not willing to show him how good a job he was doing, she bit the blanket to stifle a building moan. It didn't work, and the stallion had the audacity to stop for a moment and look over to her face for confirmation.

"Get back to work!" she all but snarled at him, and he let out a girlish 'eep!' before sticking his muzzle back into her flanks.

Before long Chrysalis found herself letting out another long moan, and she found herself thinking that she might cum in less than ten minutes- incredibly quick for a changeling, who's need for love had ultimately given them marathon sex drives (Which was more useful when disguised as a stallion than a mare, but at least they were good fakers). Then, Shining Armor's tounge flicked into a curve, and licked raspily straight along a spot she had definitely never had touched before. Then he did it again.

Chrysalis all but screamed as she came, her disguise failing instantly. Then, as Shining Armor continued to drag his tounge along her virgin g-spot she came screaming again, and the stallion relented his vaginal assault with a surprisingly wet 'Schluck' sound. She paused to catch her breath. At this point she realised how that might have sounded to anyone outside the suite and hastily reapplying her disguise, before turning to face her latest aquisition.

His white muzzle had been stained bright green, and she realised with a genuine blush that she'd squirted right into his face.

"Um, Cadance, is there something you want to tell me?" He said, going cross-eyed as he eyed his own muzzle.

"Magical condition, nothing to worry about." she lied nonchalantly.

"Did I say to stop?"

He was mid-lunge to her folds, tounge hanging out when Chrysalis' magic caught him.

"Ah ah ah, do things different this time". If she had any intention of keeping him in the long term it would help to map out his... skills. And she intended to keep this trophy quite a while.

A look of puzzlement crossed Shining Armor's face for a long moment, before resolving into one of determination.

"And no cock either!"

Back to puzzlement, for an even longer moment. But he again hit upon inspiration, and in a moment something warm, hard and pointy was thrust into Chrysalis's cunt.

'Is that his horn? Doesn't he know how much of a risk there is in letting someone else's bioforce into it?' Then with a smirk of satisfaction, she realised '...Of course he does.'

Sure enough, Shining Armor's horn, mane and face were all being coated in Chrysalis's 'bioforce', a fact she noted for later. Eventually though, he realised he could be thrusting with his horn for a long time, and while 'Cadance' was getting pleasure from it, she wasn't going to cum. He needed to step it up.

Chrysalis felt a strange, tingling sensation as Shining Armor's horn lit up inside of her. She found herself wondering what spell he was casting as he continued pumping in and out, in and out, in and out and that was NOT his horn! Still, the dildo that replaced it was being masterfully handled, and still carried the pleasant tingle of telekinesis over it. She settled back into the rythm of the thrusts, wondering what he was going to do now he wasn't busy 'being horny'. Heck, what could he do with her main hole being filled... with...

"STOP!" she shouted just as the dildo thrust back into her pussy. She pulled it out with her own telekinesis and set it back in the box without moving. Then she carefully shuffled forwards along the bed, before spinning to face Shining Armor, who was stock-still. His horn an inch from where her plot-hole had been.

"Shining Armor, did I give you permission to touch the royal plot? Or did you assume yourself privileged?"

The colt remained silent.

"Speak when I ask you something!"

"I... I though with all the toys in that box, you must have..." Shining Armor stuttered.

"Those toys were purchased for you! I have no interest in devices being shoved up my plothole!"

Shining Armor stood still, blinking, and it took Chrysalis a moment to realise he was confused by her acting out of character. Perhaps Cadance was more forgiving to this one stallion.

"I shall offer you one chance at redemption." Chrysalis announced. Shining Armor visibly perked up at this, which was a good sign in terms of how easily manipulated he was now.

"If you get me off with that cock of yours without cumming yourself, I shall forgive you, and finish you off too."

Shining Armor visibly widened his stance- of course he would be hardening up again right now, he had cum out a large part of his personality just over twenty minutes ago.

"However! If you cum inside, I shall use my magic to bottle it up in you, and you won't be allowed to cum for fourty-eight hours!

Dear sweet slutty Celestia, the thought of how he would act after penting it up for two days, if this was how he was acting now... Chrysalis was discovering quite a large fetish of hers, it seemed.

She brought her attention back to the stallion as he was now, and notice he was... moaning already? He wasn't even inside he and he was moaning? He stood no chance.

After a few moments she realised he was waiting for a cue and gave a suitably pronouncement-ish "Go!" He immediately thrust his cock deep into her, slapping his Baseball-sized balls against her leg.

'Jesus, his balls are still that big?

She thought back to the two-part spell she cast on him earlier. The first part transmuted his life-stockpile of will, and the second made his balls start churning any new will into cum.

'He must naturally be an incredibly strong-willed pony. Well, have been, at least'

His continuuing thrusts were picking up in pace, as he built towards an early climax. How he stood the pain from his balls was beyond Chrysalis.

'Damn, I was hoping he's last a bit longer than that. Oh well, at least he's still got that magic toungue.'

He started to grunt as he built towards his climax, his balls rising despite his best efforts. He was about to cum, and they both knew it. He licked his green-stained lips, and gave a final thrust.

And another.

Chrysalis looked back at him, between his increasingly rough pounds, and at once felt the telltale tingle and saw his horn glowing.

"NO, unf, MAGIC she shouted back at him, trying to be heard over his grunts. His horn immediately dimmed, but the damage was done. He must have cast some kind of arousal-lowering spell on himself.

Still, he was a mere unicorn trying to out-love a changeling. Even if she'd ended up with a head start, he was still severely outclassed.

She was waiting for him to start grunting again when he put his forehooves over her back, and started pulling himself forward like that.

'Fair enough, he's been going for nearly ten minutes now.'

Confident in her victory, she took her mind off the competition and instead spent a minute just enjoying the feeling of his cock in her. She, as queen of the changelings, had a lot of experience in the field, after all.

'Mmmm, nice and long, pity it falls a bit short of bottoming me out, maybe I can fix that at some point... Medial ring's bulky, feels good every thrust, flare's a bit on the small side though. Way he's angling it higher's nice... huh'. The realisation of why exactly he had adjusted his posture came a moment to late to stop it, and as he thrust at her g-spot once with his cock she lost the ability to talk. Twice and she nearly came. Three times, and she did.

Shining Armor somehow held the mental fortitude to pull out, despite his balls visibly throbbing with each beat of his heart.

Chrysalis, meanwhile, was shaking off the glow of her orgasm with a bloody rage. She had been beaten at her own game, by some colt she was meant to control! To say she was upset was to say Shining Armor was a bit horny.

"You know what you are!?" she snapped as she spun around on the bed.

"Hwoa-horny?" Shining Armor replied, stuttering from a moan.

By Luna's great period, sass from a hypnotised unicorn.

"A big bucking headache!" Chrysalis shouted, intentionally putting emphasis on the last word. She watched as the stallion's eyes fogged over that beautiful green, his body went limp and fell onto the ground, his- ugh, his mouth went slack.

"Close your mouth and listen to me. From now on, you can't cum outside of sex. No matter how hard you clop or what toys you use, it just won't be enough, all it'll do is make you hornier."

She glanced to his oversized balls, and another cruel idea came to mind.

"Finally, whenever you haven't seen me for, say, about an hour, I want you to start making lots and lots of... 'will'. Doesn't that sound good, to be a strong-willed pony? I think we'd both like that, so remember. When you haven't seen me for an hour, you're going to make lots and lots of 'will'."

'That should serve him right. And hopefully make him nice and loose with that love for after I tire of him.'

At this point Chrysalis remembered where she was before she got 'distracted', and headed over to 'her' dresser, carefully avoiding the puddles this time. She pulled out a set of clothes and tossed them at Shining Armor.

"Put these on." She commanded, and he complied.

It turned out to be a deep blue vest and four socks, matching his mane nicely. The vest was a bit on the tight side though, and it squeezed his chest into a mare-ish shape.

At this point actually spending effort to suck the stallion's cock seemed downright distasteful to the disguised queen, so she resolved to skip that part.

"A minute ago, after you failed to hold back and came inside me, we agreed to laugh it off as long as you tried on my clothes. After that we both agreed you should keep them on, and I sucked your cock to the edge of orgasm. Feeling better?" Having woken the stallion with a new set of memories, Chrysalis promptly took his girth oral, and started to suck. Shining Armor came almost immediately, and Chrysalis got an impressive mouthful for a stallion who had last cum three quarters of an hour ago.

'Hmm, incredibly strong taste of love, didn't realised it was that much, undercurrent of will, of course, and... longing?'

Chrysalis looked to her semi-willing slave to get clarification, but he was deep asleep.

'Oh well, there's always tomorrow. And the day after. And every day after that, when I rule the world.

And comforted by these thoughts, Chrysalis fell into a deep, comfortable sleep.

Author's Note

Haha I shouldn't write while not horny then segue into horny writing because I'm pretty sure that's a lot of words for what turned out again to be a single session. I swear I'll edit these at some point. The problem with writing clop is you're either too enthusiastic or not enthusiastic enough.
Anyways, Chrysalis is a dark bitch, and Cadance is pretty smart about being captured. I hope the characters show well in the writing, since at this point I can basically write Shining Armor however I want, poor stallion. I also hope I balanced my weird slut-hypnosis fetish with actual porn nicely.
A lot of this chapter wrote itself, but I had to start from the top twice to get there.
