“Ah think ah might be lost…” Big Mac mused to himself, his voice all but echoing through the massive series of caves he was currently walking through in search of his target. His eyes drifted over to the small but sizable river flowing through the caverns, the only indication he was going in the right direction for the most part, though that did little to ease his mind.
“Course, what’m I supposed to do when I find that little sea witch…?” The large paladin mused to himself as he eyed his equipment pack. “We came here to capture a Succubus, not a Siren. Would’ve brought a weighted net and some ear plugs if we did.”
Though Succubi and Sirens were similar enough species, they were in many ways comparable to dogs and wolves in terms of differences. In many cases, some considered Sirens to be far more lethal between the two and more difficult to capture as well.
Naturally Big Mac had some experience with said creatures, having hunted a couple in the past, thus he knew some tricks to make it easier. The most obvious being to keep an eye on the water, as Sirens generally preferred to stay submerged, especially when attempting to lure in prey. After all, Sirens could breathe underwater and move as quickly as any fish, meaning once they got you in the water, it was over.
It didn’t help Sirens were known to be fairly aggressive at times as well, not unwilling to get more physical and leap out of the water to drag their prey down to the depths with them.
Just the thought alone made the hairs on the back of Big Mac’s neck stand up, dreading the idea of potentially drowning with the last thing he’d see being a Siren’s smiling face… though admittedly that particular Siren was certainly a looker. It helped that she pretty much wore nothing but a thong, meaning he could see everything she had to offer.
Also she was a pretty nice shade of blue, which next to red, was his favorite color.
The Knight’s train of thought was quickly halted as he promptly shook his head. “Damnit Mac, get a hold of yourself. Stop acting like a teen going through puberty. She’s a monster… once Ah see her, Ah’m gonna catch her, gag her so she can’t use her spell and drag her out before meeting back up with AJ. Then we can get paid.”
As he continued to walk and eyed the water with a bit more of an edge, he could help but also look at his very exposed body, only clad in light chainmail and leather armor. Great for blocking knives and punches, and ensuring freedom of movement for attacks…but basically useless for block seduction spells. “Ah probably should’ve asked Rarity to at least put some runes on my armor. Nothing fancy, but something would’ve been nice.”
Shaking those thoughts off, he continued a bit further when a rumbling sound caught his attention.
Slowly walking forward, he walked through another cavern mouth and to his surprise, found himself entering a much larger chamber compared to the ones he’d been in. It appeared to be perhaps a few miles wide if he was to venture a guess and was positively filled to the brim with water. It was practically an underground lake if he was being honest.
However, what was most eye-catching was a massive waterfall cascading into the lake, feeding it more and more water.
Big Mac couldn’t help but be a little impressed by the sight before him, the sight only enhanced by the various stalagmites and stalactites throughout the cavern. The waterfall’s roar was even a little soothing to the ears if he was being honest.
Deciding to take advantage of the situation, he quickly pulled out an empty canteen and walked to the edge of the lake, only about twenty or so yards away from the waterfall itself. He leaned down and dipped the water carrier into the lake, allowing it to fill up, while still keeping his eyes open and aware.
“Aaahhh…. Ooohh~”
Yet as he let his canteen fill, another sound started to echo through the chamber, even managing to overpower the waterfall’s constant thunder. And this sound was far different; sweeter, softer and all too soothing, like warm honey almost.
“Hhaaaahh… aaahhhaaa~”
The Knight looked for the source of the sound, having a pretty good idea what it was, and his eyes zeroed in on the waterfall. At first there didn't seem to be anything out of the ordinary. Just a continuously flowing pillar of water, providing a mixture of light blue and white from the crashing cascade. Yet, as he looked on, he saw the image of something in the waterfall as the sound grew louder.
“Hhaaaahhhh… oooohhh~”
After another moment the shape in the water slowly step forward, exiting the water like a curtain at a bordello. A single bare leg kicked out of the water, slowly and delicately placing its foot on the water’s surface, before it was followed by the other.
In mere seconds, the beautiful form of the Siren he’d been tracking appeared. And like before, but now much closer, she was breathtaking to look at.
Light cyan blue skin, full, uncovered D cup breasts, long succulent bare legs adorned with only ankle bracelets and what appeared to be a toe ring or two on her bare feet. Her waist was similarly narrow with a flat belly, whose skin seemed to all but shine thanks to the layer of water currently upon it. Long flowing dark blue hair with a navy blue stripe running through the center, held up in a damp but still flowing ponytail
However, most eye catching was that the siren had seemingly discarded her thong, exposing her very moist womanhood to the knight.
“Aaahhh…. Haaaahh~”
The sea creature continued her song without care, seemingly dancing across the water’s surface, making sure to do several slow, graceful spins, showing off her equally full and beautiful backside, as well as dipping forward and raising her leg to the sky to show off her impressive flexibility.
Truthfully, it was an erotic display that would’ve brought almost any man to his knees, stripping himself of all armor and restraint, practically sprinting towards his end. Something the Siren knew all too well.
However… Mac was not such a man.
*CLANG*
A loud clang shattered the sound of the Siren’s song mid-dip, causing her to lose her balance and fall flat on her face into the water.
Almost immediately she jumped out, shaking with anger along with her exposed breasts, glaring at Mac. “Hey, what’s the big idea? You’re ruining my song!”
Big Mac, with his sword currently positioned in front of his shield, merely gave her a flat response. “That’s the idea.”
Sonata, more annoyed than before, tried again to start her song, forgoing the dance, but barely made it to the first note before Mac slammed his sword against his shield, sending another loud, metallic crash throughout the previously peaceful cave.
Undaunted, Sonata again tried to sing, but Mac repeated his process, and the back and forth continued for several minutes, before Sonata, visibly out of breath, jumped from the water right in front of Mac, practically frothing at the mouth. “Stop making all that racket and let me sing my song so I can seduce you already dangit!!”
A silence rang throughout the cave as Mac looked at the Siren almost stunned, though that was mainly because she’d effectively taken away the one barrier between her and him in a moment of annoyance without realizing it.
Sonata, still oblivious and seeing he wasn’t going to attack, smiled. “Great, now why don’t we pick up where we left off.” She prepared to sing again, only to stop, eyes wide as she finally noticed just how close the Knight was to her, eyes shifting to the water she’d been and finally it clicked.
“Oh….crud.”
A small bonk quickly sounded through the cave as Big Mac immediately slammed the flat of his sword on the Siren’s head, almost like a bell had been rung. Swirls replaced the Siren’s eyes before she fell backwards onto her back, legs going high into the air, giving Mac a perfect look at her exposed crotch, before dropping down, leaving her unconscious and exposed.
Mac eyed the Siren almost stunned, more so for what just happened rather than the free show. “Huh, well… that was something.”
Shrugging his shoulders he quickly got to work restraining the knocked out Siren, first taking a gag out and wrapping it around her mouth to prevent her from singing. He quickly followed up by tying her hands behind her back, as well as tying her legs and ankles together for good measure.
To end things, he then pulled out a large cleaning cloth he used for his weapon and tied it around the Siren’s waist, to at least try and preserve some of her modesty. “She might be a Siren, but Ah ain’t no deviant.” He mused to himself, figuring it'd only fair that she maintain some semblance of dignity, even in this situation.
Once his target was firmly restrained, the Knight lifted up the Siren and slung her over his shoulder, though making sure he did so with her rear pointing in the direction of his back so he wouldn’t be given side glances at her crotch when he brought her to AJ.
Last thing he needed was her wisecracks.
With a sigh he started to head back the way he came, unaware of another pair of eyes, watching him carefully as he walked away from the lake…
“Such a clever boy…” Midnight's voice echoed throughout the cavern, prompting the Knight to quickly draw his sword while holding onto the Siren, carefully looking around in an attempt to cover his blind spots. “Of course, I hope you don’t think that’ll be enough to put me down~”
Before Big Mac could retort, a pillar of lavender flames erupted from the ground before him, sending him stumbling back as it slowly morphed into a swirling vortex, one which contained the silhouette of an oval-shaped object.
As the object was levitated through the portal Big Mac was treated to the sight of his own reflection for a split second, and then like with Applejack before him, the surface started rippling before suddenly blinding the Knight with a bright flash…
Midnight smirked as she hovered above the disoriented, watching as the mirror summoned a female version of Big Macintosh from the same dimension Jackie was from. She was a rather muscular woman about the same height as her male counterpart, with longer, bright orange hair, and a slightly more curvaceous figure than Applejack, with a noticeable muscle tone similar to her counterpart.
As the unconscious woman fell to the ground, Midnight pulled out the instrument of her next experiment… while aiming an orb of magic at the Knight’s back…

----

“Mmmpph… h-hmmm…?” Big Mac groaned in confusion as he slowly came to, completely disoriented and lightheaded to boot. The Knight slowly tried to pull himself up… only to suddenly feel something push between his lips, much to his confusion. Then, the moment his vision cleared up, he found himself gazing into a woman’s emerald eyes as her tongue danced across his own, practically dominating his mouth.
“Mmmpph!? Whu-What in the…?” He stammered, his eyes widening in shock as he pulled back and broke the kiss, assuming the Siren had gotten loose and was taking advantage of him, but upon getting a closer look he realized it was someone completely different.
Confused and a little freaked out, he quickly raised his arms and pushed the woman away in embarrassment… and immediately noticed that not only was he almost completely naked save for his boxers, but there were shackles on his wrists with chains attached to them, latched onto the wall behind him. “Wha…W-who the heck are you? And where in sam hill did mah armor go?”
“Mah… mah name is Macareina…” The woman panted deeply. It was then that Big Mac noticed she was not only completely naked, save for the bizarre harness around her waist, but she seemed to be sweating profusely and she rubbed her legs together, her cheeks heating up as she gazed at the Knight before her.
“Ah’m just a farmer… Ah was… working on my farm with my little brother… and then-ooohh!” she explained between breaths before she moaned out in pleasure as she crossed her legs, the harness glowing a little in response. “S-She captured us…dragged us here… s-said she needed us for an-aahh, experiment…”
“L-Listen ma'am, mah name is Big Macintosh, Ah’m a Royal Knight. Mah sister and Ah were sent here tah capture her.” Big Mac began to explain as he tried to stand, only for the chains to glow with lavender symbols as he was immediately pulled back against the cave wall. “Dangit!”
“A man who takes charge… just mah type~” Macareina, her previous timidity gone, cooed as she crawled towards him, a lavender tint enveloping her eyes as she got closer. “Sorry sweetie, b-but Midnight made it very clear…” She explained as she leaned in close, pressing her breasts against his well-toned chest while her lips brushed against his own. “The only way Ah'm getting out of here with mah brother… is by helping her ‘test out’ her equipment…”
Mac’s eyes widened as he again struggled in vain to break the chain, his immense strength useless against the enchanted restraints. “Please wait, yah don't have tah-mmph!” He tried to protest, only for the farmer to lunge forward and pull him into another passionate kiss, Big Mac felt Macareina’s tongue slip between his lips and plunge deep into his mouth.
Before the Knight could attempt to push her away once more, the change began to glow yet again. For a moment he felt as though his entire body had shut down, but that quickly changed as Macareina continued making out with him, her lustful eyes gazing into his own as a sudden jolt of pleasure shot through his body. A part of Big Mac knew he should push this woman away, that he should break free and get out of there before they went any further… but his body remained frozen in place, none of his mental commands being registered by his body. For a brief internal moment, he found himself screaming in frustration at again not getting some kind of protection against Succubus Magic. At this point if he made it out of this, he was gonna get that rune tattooed somewhere to save him the trouble.
After a few seconds, Macareina slowly pulled her lips off of Big Mac’s, tenderly biting down on his bottom lip and pulling back a little until it snapped back into place.
“Ah ain't the only one she cast a spell on, big guy~” She purred, giving him a sultry grin as she reached down towards his boxers, or more specifically, the massive bulge that was forming underneath the fabric. “Those chains holding yah down are enchanted by her magic. The more ya’ll resist… the more energy they pump into yer body, making yah nice and horny fer me…”
The Knight couldn't help but flinch at this negative information as he slowly regained the ability to move, he couldn’t believe how much control this Succubus had over their respective minds and bodies, and all from a few well-timed spells.
But before he could dwell on those thoughts much longer as Macareina readjusted her position, forcing his legs open as she hungrily gazed down at his crotch. “W-Wait, please! Ya gotta fight-”
“Sorry partner, but ah don't wanna wait… Ah want a taste.” Macareina cut him off, giving the Knight a sultry smirk as she slipped between Big Mac's legs. Unable to keep his urges under control, Big Mac could only watch as Macareina quickly pulled down his boxers, letting his massive shaft spring free its confinements. “Now just relax… and let me take care of everything~” Macareina whispered as she gave Big Mac’s stiffening cock a long lick, dragging her tongue up from the base all the way up to the tip, making his hips shiver as his cock quickly rose before her.
The moment she reached the very tip, she opened her mouth and pulled his twitching member right into her mouth, wrapping her lips around as much of his shaft as she could.
‘Ooohh sweet Goddess above, he tastes so gooood!’ Were her first thoughts as she eagerly swirled her tongue around the head of Big Mac’s cock, wasting no time she wrapped her hands around his shaft as she began sucking and stroking in rhythmic motions. Opting to take things at a slow pace, Macareina bobbed her head up and down Big Mac’s shaft, taking in as much of his dick into her mouth before pulling back just before it reached the back of her throat. After which she dragged her palms and fingers up the length that she couldn’t sink between her lips, effectively tending to his entire length. ‘So big… so thick… ooohh ah need this in side me!’
Deep down, in a small part of the farmer's mind that remained untouched by lust, Macareina couldn't shake the feeling that something was wrong… that she needed to resist her urges and focus. But unfortunately, she also couldn’t deny just how amazing his cock tasted. The very thought of it penetrating her left her loins burning with an unsated lust, pleasure fluids leaking from her womanhood, down her legs… and that was just from the taste alone!
Soon enough, that little voice in the back of her mind was silenced, eclipsed by the anticipation of having this… this stallion’s manhood inside her…
Even though he was a man of very few words, Big Mac knew this was the Succubus’ doing, he knew he needed to resist to the best of his abilities, even if he lacked the enchanted armor his sister had been granted. He gently grasped the top of Macareina’s head as she bobbed her head up and down his cock, gritting his teeth as she flicked her tongue across the tip, each stroke and squeeze sending wave after wave of orgasmic bliss throughout his body.
And yet he pushed the entranced woman back, slowly pulling his shaft out of her mouth, inch by tantalizing inch… only for her to squeeze his shaft with her left hand just as the tip of his shaft slipped free from her lips. “Puh… please… yah need sto-”
“Nope!” Macareina chuckled, looking up at him with a smirk as she pressed her cheek against his member, which had now grown to full-mass despite his inner turmoil. “Y'all got me all hot and bothered after gettin' just a taste of yer manhood, an’ ah ain't lettin’ ya go before ah get mah fill!” Then, with a surprising amount of strength she forced his hand off her head before brushing her bangs to the side and firmly wrapping her lips around his manhood once more, her tongue gently caressing it as her head sank down his shaft.
Big Mac moaned and as nearly half of his cock was enveloped by Macareina’s delicate lips, while the half that remained free was continuously stroked up and down in tandem with the farmer's mouth, each stroke halting just as her hand reached the saliva coated section before dragging back down to the base, covering more of the Knight’s shaft with her saliva as if it were lube.
“P-please… n-no… no more…” Big Mac tried to plead as he pulled against the chains in one last ditch effort to resist the spell. But sadly, no matter how hard he tried not to justify it in his mind, he couldn't deny just how much he was starting to enjoy it, nor could he resist the temptation to start bucking his hips. At this point he actually contemplated potentially knocking the lust crazed woman out. Yes it was hardly chivalrous or noble, but she wasn’t leaving him with many options. Though at this point he feared he didn’t have the strength to do it.
“Mmmpph…” Macareina moaned around his shaft as, her lustful eyes gazing up at him as her head bobbed up and down his cock, continuously jerking him off. She then pressed her tongue up against the base of his shaft and dragged it up his entire length. Taking a moment to wrap her lips around the tip, Macareina pursed her lips and held the very head of his cock in place. “It feels good… doesn't it, Big Mac~?” She whispered around the tip, teasing the Knight further.
Within the depths of Big Mac’s lust-addled mind, a small snippet of resistance wormed its way to the surface. Biting his lip, he desperately tried to pull against the chains. “N-Nope-ggrrkk!” Unfortunately, another jolt of pleasure shot through him, prompting him to buck his hips in response.
“Ah-ah-ah… no lying, sweet thing~” The woman giggled, staring straight into his eyes as she planted a few soft kisses along the tip before sucking it back into her mouth.
Letting out a sigh of defeat, he gave the farmer a solemn nod embarrassingly muttering “Eeyup.” under his breath. The farmer's only response was a light chuckle, her lips curving upward as she grinned around his dick before bobbing her head up and down his shaft yet again, taking it even deeper each time.
While the Knight had bedded his fair share of women, he had to admit that Macareina was practically perfect when it came to oral stimulation, the way she teased him while sucking on his shaft with unrestrained enthusiasm… under any other circumstances he'd be encouraging her to continue.
As he enjoyed the feeling of her warm and eager lips around his cock, Big Mac couldn't help but feel a small bit of respect regarding how experienced Macareina appeared to be, pulling more and more of his manhood into her mouth… and right down her throat. ‘Does this woman even have a gag reflex!?’

----

Midnight, having rescued Sonata early on, could only lick her lips as she watched the duo through a crystal ball within her hidden chamber once more. She had to admit, she'd honestly hadn't spared the male Knight a second thought due to him not wearing the more “enhanced” Armor, but after introducing him to his other self, he proved to be more entertaining than she'd anticipated.
“Damn, wasn't expecting this Knight to be so well-hung! Aria always said they were just ‘limp-dicked prudes’!” The Siren giggled as she watched their captive eagerly sucking the Knight off, his hips twitching violently as Macareina bobbed her head up and down his shaft. “Definitely gonna let my sister's know about this stud!”
“Well, assuming I don't keep him for myself…” The Succubus replied with a mild chuckle as she started taking notes regarding their actions. “His resistance is somewhat commendable, given he lacks the Armor his sister was granted… not that it'll help him in the long run.”
“So… any chance of you bringing over more genderswapped cuties?” Sonata mused, tilting her head as she casually trapped the mirror, the surface rippling at her touch. “Cause watching them go at it is leaving me a little hot and bothered too.”
“Not anytime soon, I'm afraid.” Midnight sighed as she continued jotting down more notes, casting a glance at the mirror herself. “I'm not sure why, but apparently after certain amount of time whoever was summoned through the mirror will be pulled back to their own dimension.” She explained, recalling how “Jackie” had vanished back into the mirror after his “encounter” with Applejack.
However her expression of disappointment was quickly replaced by a sultry smile as she snapped her fingers, causing the harness around Macareina’s waist to start glowing. “Of course, there are plenty more experiments I can try out in the meantime…”
“Oooo! What's this spell do?” Sonata asked eagerly.
“It activates a special harness I've been developing, figured I'd test it out here.” Midnight smirked as she traced a few more symbols through the air, she pressed her finger against the center and slowly dragged it down, setting the strength to the maximum setting. “Let's start with… the highest setting~”

----

“OOOOHH!? WHOOOOAAA!!” Macareina yelped in surprise as a sudden torrent of pleasure shot through her loins, her hips now twitching and shuddering as something buzzed against her nethers. From within the harness the gem glowed as an aura manifested in the form of a medium-sized dildo, vibrating intensely it swiftly slid between her pussy lips. “Ah! O-Ohhh dear Goddess… ” She moaned out, instinctively pulling one hand from Big Mac’s cock and firmly grasping her harness in a desperate attempt to yank it off.
“Y-Ya’ll okay…?” Big Mac hesitantly asked as he watched the trembling woman, partly thankful that her oral assault on his manhood had momentarily ceased, yet extremely worried over what the Succubus was doing to her. “Do you-ngh… need help-”
“AAAHH!!”
He was cut off as Macareina shrieked in ecstasy, throwing her head back as the buzzing aura slipped into her pussy, the tip alone racking her body with pleasurable sensations she'd never imagined were possible.
“N-No, it’s… it feels… amazing… I-I can't-OH! OH, OH, OOOHHHH~!” She gasped, her voice trembling as she felt the aura push another inch inside her, then another, and then another, all the while violently rumbling and vibrating against her inner walls. “Hhaahh… aahahaha… ooohhh f-fuck I need… I need your… your…” Was all Macareina managed to say, panting as she placed her hands on his legs to help brace herself. Macareina’s gaze was quickly drawn back to Big Mac’s manhood, still standing tall and slick with the farmer's saliva while twitching every few seconds with her eyes following every movement.
“M-Ma'am…? Mah… Macareina…?” Big Mac called out as he vainly struggled against his chains, desperately trying to snap the woman out of her stupor. “C-C’mon now, ya gotta snap out of it!”
Despite her hair having fallen across her face, Big Mac could tell the harness was pushing her very close to her limit, a hunch made even more evident as the woman’s face sank back down between his legs, her hips jerking in random directions as the magic aura soon reached its full length inside her womanhood. Then, without even taking a moment to catch her breath, Macareina immediately wrapped her lips around his dick and eagerly resumed her blowjob.
“Hrrkk, guuhh! F-FUCK!” Big Mac groaned as he shut his eyes and leaned back against the wall, his shaft twitching inside her eager mouth as dollops of pre-cum leaked out from the tip and were quickly slurped up by her tongue. Unlike previously, the entranced farmer didn't even bother grabbing his cock, forcing her head down almost halfway to the base instead, the saliva coating his cock a clear indicator of just how far Macareina could go down on him.
‘Dangit… c-can't hold on… need… need tah f-focus!’ The Knight thought as the chains glowed once more, pumping another dosage of lustful energy into his body and forcing him to involuntarily buck his hips.
Macareina, too focused on the buzzing sensations didn't even bother trying to keep a consistent pace like before, instead choosing to sloppily bob her head up and down his manhood, not even flinching when it touched the back of her throat, her loins becoming numb from the constant vibrations.
“Mmph, g-glurkk… hrkk, guulk!!” She grunted, her hips trembling as the aura continued vibrating against her sensitive insides, and yet not once did she let Big Mac’s massive member slip free from her lips. ‘Mmmhmhmhm… this cock… it's my prize… it's mine… all mine~’ She thought, her eyes rolling back as wave after euphoric wave shot through her body, further dulling her mind with each passing second while pushing her closer and closer to her edge.
“F-F-Fuuuuck… Ah… Ah can't… k-keep… keep up… nnggh!!” The Knight groaned, right before jerking his hips upwards and shoving his manhood further her throat.
It was the only warning that Macareina got.
She then froze, her eyes widening as Big Mac’s seed erupted from his cock, shooting ropes of cum down her throat. The Knight gazed down at the woman in panic, half-expecting her to start choking as her cheeks puffed up before his load burst out from the corners of her lips… but the moment never came. Instead, he was treated to the sight of Macareina wrapping her arms around his waist as she gulped down spurt after spurt, drinking down his seed without so much as flinching!
‘Sweet goddess above… what in the name of Tartarus is this woman!?’ Were his only coherent thoughts as the farmer gulped down another load before pulling back, her lips sliding back up to the tip as a few more ropes of cum flew across her tongue.
“Oh… f-fuuuck, that… f-felt amazin’...”

----

“Damn, she swallowed it all down like a pro~” Sonata whispered as she watched Macareina finally released his cock from her maw, eagerly swallowing his last few spurts of cum. “Like, does that woman even have a gag reflex?”
“Mmmm, if only I could keep her… I'd love to test out that throat of hers~” Midnight mused as she bit her lower lip, rubbing her legs together while her own shaft twitched in anticipation. “Now then, let's make sure sweet Macareina gets her due…” She smirked before turning her attention back to the symbol.
The Succubus then pressed her index fingers against the center and spread them apart, causing the harness to glow once more. The aura finally ceased vibrating and retreated into the gem, said aura then proceeded to spread across the front part of the harness and opened a hole right above her quivering pussy. “After all, it wouldn't be right to leave your partner unsatisfied~”

----

“Y-Ya’ll better not… b-be thinking… yer done…” Macareina breathed out after swallowing the last of his cum, slowly and carefully us Big Mac’s knees to climb to her trembling feet, positioning her hips right above his own, with her bare crotch mere inches above Big Mac’s still-hard member, coated with her saliva “Ah… Ah still need ya… inside me~” She cooed, far too blissed-out to even question where that opening in her harness had come from.
The Knight froze, almost petrified by the farmer's more aggressive tone as she firmly grasped his shoulders.
“W-Wait a se-ngggh!?” Big Mac tried to protest one final time, but a quick spike of a lustful energy shot through the chains and into his body, prompting him to instinctively thrust the tip of his cock up against her soaked slit. ‘C-Can’t… can't… keep… holdin’ back…’
“Aaahhh, now we're talkin’!” Macareina moaned, her eyes quickly closing as she leisurely lowered herself back down onto his lap, her hips shuddering and her legs shaking in bliss as she felt the Knight’s stiffening cock cock parted her glistening wet folds and penetrated her pussy.
“Haah! Aahh… ooohhh damn! Mmph… hah, hah, hah…” Macareina could only moan and squirm as she gripped Big Mac’s shoulders, twisting her hips in order to work his shaft deeper inside her. The feeling of this man, this stallion piercing her depths, his shaft stretching her inner walls open as they clenched around it… everything the harness had put her through now paled in comparison.
As the chains binding Big Mac continued to pump more energy into his body, he found himself panting deeply as the farmer gently lowered herself down his manhood, inch after agonizing inch disappearing inside her, the saliva combined with her pussy juices allowing him to slip easily inside her. Her vaginal walls were so warm, wet, and… tight, almost as if they were hugging his shaft the deeper it went, which made it even harder to resist the urge to move his hips any more, despite wanting nothing more than to thrust his remaining length inside her.
And as much as he hated to admit it, that look on Macareina’s face, her expression of unrestrained carnal lust… it made his dick even harder knowing she was that way because of him. “M-Macareina… A-Ah sorr-mmph” Big Mac groaned out, knowing he was on the verge of losing control at any moment now.
But as the farmer reached the very base of his shaft and their crotches finally met, Macareina wrapped her arms around his back and pulled him in close, locking lips with the Knight once more. “Mmaawwhh… fuck me, Big Mac~” She whispered through the kiss, slipping her tongue into Big Mac’s mouth as she continued making out with him. “Take me, Ah’m… Ah’m all yers…”
And just like that, any reservations he’d had before either disappeared or were being completely drowned out by the almost insatiable urges that were now beginning to overwhelm him. Without so much as a word, Big Mac wrapped his hand around Macareina’s hips before cupping her cheeks and thrusting his cock in and out of her depths. The Knight’s hips jerked upwards as he leaned into the kiss, their tongues practically wrestling for dominance as the farmer bounced up and down on his manhood, her pussy clenching and hugging every inch of his cock with each movement smearing her lustful fluids across his shaft as it pumped in and out of her pussy.

----

“Oooo! They’re really going at it!” The Siren giggled, wishing she had some popcorn and she watched the couple ravish each other, completely lost in the throes of lust as any semblance of resistance was eclipsed by immense pleasure. “Last time I saw people going at this hard was during that pirate orgy me and my sisters pulled off!”
However, at that very moment Midnight felt a certain surge of magic shot through her body. Momentarily turning her attention away from the erotic display, she quickly summoned another crystal ball. The image within shifted to display the female Knight, having finally awoken, now traveling through the tavern and approaching the chamber she'd had spotted Midnight in.
Applejack was getting closer, and no doubt would greatly hinder her experiment, or worse, figure out the methods behind them before she could get any more data.
‘Ugh! Of all the rotten luck… maybe I should've strengthened the spell to keep her knocked out longer…’ She mentally mused and she turned back to the glowing symbol that controlled the harness and quickly traced a circle around it, clenching her fist as it started to glow more intensely. ‘Just great, and I was hoping to keep the big guy for later…’
Sonata noticed this abrupt action and tore her attention away from the first crystal ball. “Uuuhhh, what exactly are you doing?” She asked, tilting her head in confusion.
“We have an unwelcome guest approaching. And as much as I hate to leave an experiment half-completed, I'm gonna have to speed up the process…” The Succubus explained as she pressed her finger right against the center.
“Aww, I wanted to draw things out a little longer…” The Siren pouted in disappointment that she went back to watching.

----

“OOOHHHH!? AAAHH!! AAHHAA!? OH! OH! YES! YEEEESSS!! J-JUST LIKE THAT!!” The farmer cried out, hollering in ecstasy as the harness immediately started vibrating again. This, combined the feeling of the Knight dick pounding her pussy quickly sent her over the edge, prompting her to immediately started slamming her hips at a more violent pace. “MMPH! YES! AH! AAAHHH! OOOHH YEAH!!”
While taken aback by this sudden shift in personality, Big Mac immediately felt the vibrations from the harness rumbling throughout the walls of Macareina’s body, her vaginal walls vibrating around every inch of his cock.
“Fuck… f-fuuuck… ooohh damn!” He grunted, pumping his throbbing shaft into the depths of her womanhood, practically hitting her cervix with every thrust! Big Mac, barely able to focus, witnessed Macareina fluttering her eyelashes while her eyes rolled back, her tongue falling out in ecstasy as she screamed at the top of her lungs. It didn’t take long for them to find a steady rhythm despite this, never once slowing down their pace as they pulled each other in closer with every thrust.
“AHN! AHN! BIG MAC! K-KEEP GOING! HARDER! OHHH!!!” Macareina gasped, the overall pitch of her moans ascending after every breath, taking his pistoning manhood as fast and deep as his body would allow, and all while coating it in her pleasure nectar, with some of it drizzling down onto the floor. The farmer then groaned the loudest she had so far, picking up her already quickened pace to hump the Knight at double the speed from before. It was almost painful receiving so much of his manhood at once, but whatever pain she experienced was quickly replaced by overwhelming sensations of pleasure. “SO GOOD!! SOOOO FUCKING GOOOOOD!!”
She was already so close… she was going to lose it soon…
“AHHH… ALMOST… AH’M ALMOST… TH-THERE… I-HHHAAAA!!” The farmer instantly lost her train of thought, shutting her eyes as her entire body suddenly went stiff. Her legs shuddered and her toes curled as she was brought to climax, gasping in orgasmic bliss as her vaginal walls convulsed and tightened around his shaft. “B-BIG MAC, I’M GONNA… I’M GONNA C-AHHH! OH, GODDESS, I’M CUMMING! H-HARDER!! AHHH!!!”
And then, the dam burst.
Macareina slammed her hips down onto his shaft as she came, holding him in place as she buried his manhood inside her rigid body, trembling in his embrace as pleasure fluids sprayed all over Big Mac’s cock. “Big Mac… oooohhh Big Mac~” The woman gasped as she held the Knight tightly, shuddering non-stop as she rode out her climax.
The aforementioned Knight immediately followed, the feeling of the woman's insides throbbing against his manhood while climaxing around it… combined with the continuous vibrations from the harness… it was all too much for him. After a few more thrusts until his dick twitched before spraying his thick load deep into her depths, cumming in tandem with the farmer in his arm, spurt after spurt, each rope of cum painting Macareina's insides, filling her up to the point where it overflowed and oozed out the sides around his cock.
Their respective climaxes lasted for several seconds before they both felt themselves fall limp, the two now nothing more than a panting, sweat-drenched mess, the vibrations from Macareina’s harness finally starting to weaken… before coming to an abrupt halt.
“Every… drop…” Macareina managed to whisper. “Give it all… tah me…” Macareina panted as she collapsed against Big Mac, basking in the afterglow of the most incredible orgasm of her life.
The Knight was barely able to focus by this point, the spell of the succubus having taken its toll on his mind and body. With a weak groan, Big Mac eased his softening member out of her pussy, letting it slip out of her womanhood with one last spurt of cum. Thick goopy mixture of their respective fluids oozed out of her pussy, forming a puddle on the floor in the aftermath of their own climaxes.
It was finally over.
“Ah wish Ah had someone like ya back home… you know exactly how to treat a lady~” Macareina whispered. She rested her head against his shoulder and planted soft kisses on his neck.
Big Mac said nothing as he leaned back, his arms slipping off her back as he gazed down at the panting woman before him, her body glistening with sweat, something about it just made her even more alluring, to the point where his cock, despite being completely flaccid, twitched at the mere idea of fucking Macareina yet again.
However, at that very moment a light blue aura started to engulf the entirety of her body, the mirror portal now summoning her back to her home dimension just as it had done with Jackie. Macareina, seemingly aware of what was transpiring, told back to gaze into his eyes. She then leaned in and planted one final kiss on his lips.
“Heh heh… so long… sugarcube~” She whispered as she slowly faded away until only the aura was all that was left, leaving only the harness behind as it wafted deeper into the cave.
“W-What the…?” Big Mac groaned as he tried to pull himself up in an attempt to follow her, but quickly sank down as the fatigue caught up to him.
“Real shame that I can't keep her, but at the very least the experiment was more successful than I could have hoped for…” A familiar voice chimed in, glancing to his left, Big Mac was treated to the site of none other than the very Succubus they had been pursuing covering over him. Terror quickly raced through his body as he realized just how helpless and vulnerable he was right now, without so much as a dagger to defend himself with…
“Oh relax, as amusing as it would be to see what that siren would do to you…I've already gotten what I needed from you two…” She smirked that she snapped her fingers, causing the chains binding him to glow one last time before shattering into pieces.
"Ugh… whuh… where… where's Macareina…?" He groaned
"She's back where she belongs." Midnight replied as cryptically as possible, not exactly lying, but making sure he didn't know the full truth. “Anyway, your sister should be here shortly, and we can't have a Knight of your caliber looking so indecent, now can we?” She cooed as she leaned down towards the helpless Knight, giving him a rather generous view of her tantalizing breasts as her hands began to glow. “But don't worry, I'll make you more presentable, consider it my way of thanking you for helping with this little project, ta-ta~!”
Before he could say another word, Midnight likely tapped her glowing finger against his forehead, and then everything went dark…

“…Mac? C’mon big bro, wake up!”
Big Mac groaned at the sound of another familiar voice as he blinked in confusion, his body still tired out from fatigue leaving him unable to fully move. As his vision cleared up, he was treated to the sight of his little sister gazing down at him with a panicked expression.
“Oh thank goodness! Ah was afraid that dang Siren had gotten ya!” The Knight sighed in relief as she helped him to his feet.
A sense of nervousness shot through Big Mac as he looked down at his waist…only to discover that his pants and shirt had been restored… although the same couldn't be said for what was left of his armor.
“Ah… ah was close tah nailin’ the Siren. But then that dang Succubus got the drop on me…” He tried to think back to that encounter, only for a pink tinge well up on his cheeks as he quickly shook his head. “Ah… Ah must’ve blacked out, can't remember anythin’ after that… can’t believe Ah just walked right into all that.”
Applejack winced at this information, clenching her fists in irritation..“Dangit, same thing happened to me… this ain't right. She was ready fer us!” She grumbled as she guided her brother back towards the entrance, occasionally glancing over her shoulder just in case the Succubus tried to ambush them. “We gotta report back to Captain Shining Armor, immediately!”

As she watched the retreating Knights through her crystal ball, Midnight smirked as she read through her notes, going over all the data she had gathered from the enchanted mirror, Applejack’s armor, and her prototype harness. While she'd run out of time regarding the genderswapped versions of the two Knights, Rarity’s custom-made armor had proven much more effective than she'd anticipated.
Sonata, having overall concluded their business, had already retreated into the rivers that ran through the caves, leaving the Succubus alone with her mirror.
“Let's see, I'll have to relocate before that ever-persistent mercenary zeroes in on my location again… but where to go?” She mused to herself and she glanced down at the back of her hand, the tracing symbol glowing lightly. “Klugletown might be the best option, but-”
~I suppose I have you to thank for breaking these two in~
A shiver ran up her back as a deep voice echoed throughout her chamber, narrowing her eyes the Succubus turned towards the mirror… and froze.
She saw herself… or rather what looked like a male version of herself, while the mirror’s rippling surface made it hard to properly see exactly what he looked like, she could make out a few details. His body seemed a lot more slender and feminine than most men, with similar wings and some sort of tiara that resembled horns.
‘An… Incubus version of me?’ Midnight thought as she reached out towards the mirror… only for the surface to start rippling once more, the vision coming more blurry with each passing second as the Incubus faded from view.
~Shame really, we could’ve performed some interesting experiments together~
Those were the last words she heard before the surface shifted back to normal, leaving Midnight alone with her thoughts… and the various possibilities for future experiments this mirror presented.
“Heh, if only…”
