Diamond Dog Double Dealings

Sinking to her knees, overwhelmed by a frailty like she’d never known, Alga clutched at her bosom. “W...what did you do to me?!” she wailed, noting that her voice held a touch more baritone.

“What did I do to you?” Leech mocked, sauntering over to the stricken woman. “I didn’t do anything. You’re the one who dank that potion, so you have nobody to blame but yourself.”

The diamond dog’s eyes sailed to the bottle she’d drained, as a pervasive warmth spread through her body. “A...am I going to die?”

“Die?” the mare repeated, looming over her once mighty foe. “Nah, you ain’t going to die. But…” she chuckled, staring down at the canine, “I am going to bring you to heaven…”

Before Alga could ask what the unicorn had meant, a cramp hit her groin. Just above her meaty entrance, the almost ignorable sensation grew into an intense ache. Glancing down, wondering what in the nine hells was going on, her concern mounted exponentially. Her once mountainous breasts withered before her very eyes, shrinking to nothing more than a pair of flat, barely defined pecs; as if the sight wasn’t unsettling enough, her loins befell a far more terrifying fate.

Hunching forward to inspect herself, she watched the flesh on her groin slowly remold itself. Her glorious lower lips fused together, forming into a furry nub. Larger and larger the bud grew, until an inexorable and horrifying realization struck her. To her abject horror, the unmistakable form of a sheath and two balls emerged upon her crotch.

“Hot damn, that potion really did a number on you!” Leech laughed, positively beaming.

Looking up, snarling at the meddlesome mare, Alga was hit with another profound truth. Not only had her femininity been robbed from her, but a substantial amount of her size as well. Peeking at her arms and legs, surveying the extent of the transformative elixir, she discovered she’d suffered a heavy toll. Gone was her magnificently sculpted mounds of muscle, replaced by slender, barely toned limbs.

To say the situation was bizarre would be an egregious understatement. Not but an hour ago, Alga had been a towering colossus of a woman, but that was gone. Imprisoned within the shell of a weak, feeble male, her mind was left wholly intact - well, mostly intact. As her form had changed, so too had a subtle, almost imperceptible shift happened with his thoughts.

He still felt the same, for the most part, although the abrupt shift in biological sex had inexplicably and smoothly imparted a sense of masculine self. It wasn’t like he’d ever thought of himself as exceedingly feminine anyway, since he had a domineering streak a mile long - still, the circumstances confused and angered him. Regardless of his psychology and greatly reduced physical prowess, he knew one thing for certain - he was pissed.

“You cheater!” he blared, unsteadily getting to his feet and scowling at the pony. “You knew this would happen and you tricked me!”

“I didn’t know you’d steal one of the elixirs, but I resist from tricking you into drinking it. It’s not that big of a deal, since the tonic will wear off in a day or so - besides, we’re not done with our little competition yet,” she hummed, as her horn went alight.

“Our competition will be over when I beat you to a - H...hey!” Alga blurted, feeling one of his arms being pulled upward.

Glancing to his wrist, seeing that a length of rope had bound his limb, he snarled. Pulling at the binding, trying desperately to free himself, another three lengths of cord swiftly encircled his other arm and both his legs. In a last ditch effort, only just coming to grips with how dire the situation was, he turned and lunged at his tormentor - only to find himself levitated into the air.

“I don’t know why you’re fighting this so much,” Leech sighed, magically guiding her captive to the mattress. “Trust me, you’re gonna love what I’m gonna do to you.”

“Do your worst, whore!” Alga spat, fruitlessly thrashing about while his limbs were fastened to the bedposts.

“Worst?” the mare parroted. Holding a hand to her bare chest, as if stricken, she deftly secured the rebellious canine and relinquished her sorcerous grasp. “You definitely won’t get my worst,” she purred, hungrily eyeing his lithe, restrained form, “because only bad dogs get that…”

Only able to move his head, Alga studied the ropes lashing him to the bed. Not but twenty minutes ago, he could have snapped the slender cords with little more than a flex - now, having virtually all his strength and bulk, he was virtually helpless. Knitting his brow and baring her teeth, a low growl crept past his curled lips.

“Well, well, well…” Leech cooed, crawling onto the mattress and between the lad’s legs. Running her face up his thigh and bringing her snout to his delicate, fuzzy coin purse, she drew a breath. “Nice and ripe.”

“Don’t you - Gah?!” he gasped, as she kissed and suckled her way up his package.

The sensations which greeted her were both wholly alien and contemptibly pleasurable. The mare’s touch on his nuts was pleasant, not unlike having her mons rubbed, although that was only a prelude for what was to come. As the pony’s tongue dug into his sheath, teasing the tip of his length, his breath hitched in his throat.

WIthdrawing her muzzle and resting her cheek on his crotch, Leech tenderly stroked and fondled his newly acquired equipment. Though he was no stranger to playing with a male’s junk, being on the receiving side of such treatment was definitely a new experience. Screwing his eyes shut, trying and failing to ignore the slutty pony’s affectionate hands, he angrily threw his head to the side.

“Look at that big boy,” Leech whispered, drawing his attention downward.

Much to his chagrin, in spite of his shame and resentment at his metamorphosis, his body acted of its own accord. Standing tall, no more than a few inches in length and maybe an inch in width, his poor cock stood as proudly as it could. Covered in rosy pink flesh, from pointed tip to knotted base, small veins traced along his shaft. So far as he could tell, it was a fully functional dick, even if it wasn’t by any means an impressive endowment.

Staring past his lamentable prick, locking eyes with the succubus who had trapped him, Alga did his best to put on a brave front - sadly, it was undone in an instant. The mare simply pursed her lips and gently blew upon his tool. Wincing, he shuddered at the feeling of cool air upon his extraordinarily sensitive flesh.

“Puppy’s cold?” she sweetly inquired, pushing herself up and bringing her snout to the rigid length of canine meat. “Let mama warm you up…”

Before Alga could say a word, the mare’s soft, pouting lips had wrapped around the head of his tool. Pressing her head lower, while keeping her eyes glued to his face, the temptress worked him into her muzzle. The experience was indescribable, vastly differing from anything he’d ever felt before.

His cock seemed to have all the sensitivity of a clit, although it was many times larger and unprotected by folds of flesh. The feeling was beyond reproach and bordered on the divine, yet that did little to quell his anger with being mistreated so harshly. He’d temporarily lost the body he’d spent a lifetime sculpting, he’d been tied to a bed, and how he was being teased by some unhinged and extraordinarily depraved equine - it was all well beyond demeaning.

Gritting his teeth, with his treacherous body succumbing to the carnal advances of the horned beast, he watched his shaft disappear into her maw. Skillfully running her tongue around what had to be the most sensitive portions of his cock, specifically around the tip and underside, she fellated him like a seasoned veteran. Struggling against his bonds, what little strength he had left fled from him.

As much as he hated to admit it, Alga couldn’t look away from the show itself. He couldn’t rightly say why it was so entrancing, seeing the pony bob her head and virtually inhale the entirety of his cock, yet he found himself under her spell. Grasping at nothing, in the fleeting throes of opposition to being so easily bested and bound, his hips mutinously bucked into her face.

Quickly withdrawing, freeing her muzzle, she wormed a hand forward to caringly stroke him off. “You think that felt amazing, Pup, you ain’t seen nothing yet…”

Averting his gaze and feeling his cheeks darken, Alga looked for something - anything to occupy himself. Her treatment was tantamount to torture of the most lecherous sort and he was not about to give her the gratification of a response - that was, until the mattress shifted beneath him. A sudden movement caught his eye, as her hand pressed down to the side of his head, while she crawled up and straddled him.

Without a word of warning or so much as reaching back to align him with her entrance, she taunted his head with soaked marehood. Part of him wanted to scream, to bite and scratch the predatory floozy and flee, yet another, far more insidious side of him pined to know what wonders her nethers afforded. In the end, it mattered little, as she glacially impaled herself upon his throbbing and painfully erect prick.

If Leech’s lips were a glimpse of heaven, her hot, velvety interior was the grace of nirvana itself. Despite having been worked by the substantially larger toy, not to mention the untold number of cocks the slut had taken in the past, her confines were exceptionally snug. All it took was feeling the first inch or so slip into her canal for his composure to fracture. Snarling, he drove his waist upward and caved to his budding urges.

He’d always had a penchant for controlling any and all sexual situations he found himself in, although this was different. Granted a male’s body, having the ability to fulfill the biological need to claim a mate and sow his seed within them, was inspiration incarnate. While it took him a moment to comprehend what the motivation was, he quickly found himself compelled to follow through with the natural drive to claim her as his mate.

“Oh god,” Leech groaned, throwing her head back, “you’re just so big!”

The admission was a bit perplexing to Alga, causing him to slow. While it was a bit surprising to see the strumpet enjoying such a modest tool, perhaps she was simply overcome by the superiority of a dog cock. Smirking to himself, an idea coalesced.

“If you let me go, I could give you more…” he murmured.

“R...really?!” Leech exclaimed, taken aback by the offer.

Alga simply nodded and smiled, moments before his bindings were magically undone. Clasping his hands on the pony’s hips, he braced his legs and started fucking. Though he had no real experience wielding a dick, he’d used strap-ons and been screwed enough to have a firm grasp of the basics. With his instincts driving him forward, as the masculine portions of his altered brain rallied, he put his body to work.

“Yes!” the mare yowled, feverishly bouncing upon him and moving in tune with his wild rhythm. “Dog cock is the best!!!”

Liberated, free to conquer the unicorn, Alga’s eyes wandered over the pony’s body. The freedom to plow his mate bolstered his confidence and ignited a fire within him. Contrary to when he’d been tied up, staving off the enjoyment his altered body offered, he embraced the remarkably wondrous feeling of truly rutting a female.

“More, please!!!” Leech pleaded, leaning forward to lick and kiss the lad’s chest. “I...I want your pups! Pump a litter into this poor, pathetic pony!!!”

“Good,” the pup hummed, spanking the unicorn’s ass.

Hearing her beg, knowing he’d broken her and shown her the light of canine superiority, Alga’s pace quickened. Something about the pony’s admission was deeply gratifying and elevated the experience to the next level. Thrusting into her with everything he had, feeling his knot pop in and out of her winking marehood, he accepted his role. If she wanted him to claim her womb and gift her with a litter, that’s exactly what she was going to get.

Perhaps he’d been wrong about her - perhaps she wasn’t as depraved as he’d once thought. Though she was loose - at least, in regards to getting her to the bedroom - her taut marehood stood in stark contrast to her previous actions. Maybe, just maybe she simply hadn’t had a proper breeding from a capable canine; if that was the case, he would be her envoy to a world of unparalleled joys.

“D...don’t stop,” Leech sputtered, licking his neck and clamping down around him. “I...I need it inside.”

Banging her like a beast possessed, Alga’s endurance dwindled. Had she still been a woman, she felt sure she would have outlasted the pony for a second round - now, with the body of a young man who’d just been begged to knock up and lay claim to a slut, he found himself on the back foot. Sinking his claws into her ample, foal bearing hips, teetering on the brink, a sharp pain flung him over the edge.

As Leech bit his neck, he screwed his eyes shut and howled. Thick, virgin seed coursed through his throbbing length, just as he hilted within his mate. His knot pulsed in tune with his heart, swelling ever more and trapping his essence within the pony’s depths. The ecstasy which hit him was only overshadowed by the fact that he knew no stallion could ever hope to best his performance in bed.

Fitfully humping, as the final few shots of his cum were disgorged into the pony, Alga rested his head to the side. Maybe being a male wasn’t all that bad; if he could convince more mares to serve the diamond dogs, as either concubines or broodmares, he would be doing his country a great service. Awash in the rapturous euphoria of his climax and his flights of fancy, he felt the unicorn shift atop him.

In the blink of an eye, his limbs were pulled away and lashed to the bedposts once again. His release had completely drained him - figuratively and somewhat physically - and made him even more vulnerable than he had been already. Dumbfoundedly cracking an eye open, leaving his bonds untried, he exhaustedly peered down at the mare. Spying her moving over him, crawling on her hands and knees towards the head of the bed, his pupils shrank to pinpricks.

“Now,” Leech began, bringing her leaking, cum filled cunt over his face, “be a good pup and lick me clean.”

Opening his mouth to object, without thinking about his actions, Alga’s muzzle was filled with the slick, viscous remnants of their romp. Salty, cloying, and a bit bitter, his very first load of spunk washed over his tongue and to the back of his throat. He’d lost, there was no doubt about it, and now he was being shamed for his failure.

Be damned if he could explain what infernal hellscape the succubus had crawled from, but she’d surprised him for the second time over a very brief period. Honestly, he wasn’t sure what to think of the hooved beast he’d stumbled upon. If she had faked everything, it was an unparalleled act - if she had been genuine, she had some unholy ability to rebound from an orgasm. How she’d had such superb control of her sex was another confounding issue, although it mattered little - in the end, Alga begrudgingly accepted his defeat and lapped his cum from her nethers.

Even though he’d been well and truly trounced, his honor demanded he service her properly. She may have tricked him with her guile and deception, although he had been the one to unwittingly drink one of the potions she’d brought with her. If he hadn’t been foolish or foolhardy enough to down the cursed brew, he would have surely won and claimed his bits by now - sadly, that was not the case.

Bucking into his face, eagerly toying with her breasts, the mare clamped her thighs around his head. Plunging his tongue into her, he silently prayed that ponies had a g-spot in the same area as diamond dogs. After a moment of probing, his suspicions were confirmed. The unicorn grabbed his hair and simultaneously pulled him deeper as she bore down upon him.

Willing to accept the unicorn’s orgasm as a consolation prize, Alga expertly applied his substantial oral silles against his foe. Judging from the faint tremble in her thighs to the way her breathing changed, the mare had to be close. Going in for the kill, he stroked her clit with his top lip while continuing to caress the erogenous zone with his tongue.

Gasping aloud, her marehood spasmed and painted his face with feminine juices. Closing his eyes, shielding them from the warm cocktail of her nectar and his jizz, he bided his time and waited for her to dismount. As the seconds passed and her shaking subsided, she eased her grip and patted his head.

“Just a few more licks and I promise I’ll let you go. Sweet, merciful Celestia, you diamond dogs have some amazing tongues,” Leech praised. Resting on her knees above him, hoping to get a bit more lip service out of the pint-sized pup, Leech boastfully waggled her hips. “Once you’re done down there, maybe we can take a break and grab a bite before the third round.”

“Mmmph mph?” Alga asked, his question muffled by the plush thighs and drenched snatch against his snout.

“Yeah, third round!” the mare repeated, somehow having understood his incomprehensible query. “Best out of three. We’ve both got a win under our belts, so we’ll have to settle it for those fifty bits.”

Wriggling his head upward, the canine knit his brow. “I’m surprised you have that much honor…”

Leech shrugged, reached down, and gently guided the lad’s face back to her sex. “I’m not that bad - that is, unless you want me to rob you blind and leave you tied naked to a bed,” she tittered, as the canine pressed his tongue into her.

Glowering up at her, hearing her lighthearted giggle, Alga wasn’t sure what to think. Whoever or whatever this creature was, he wasn’t going to underestimate her again. With a third, final round guaranteed, knowing he had one more chance to claim victory and regain his pride, he closed his eyes and focused on the task at hand. With a rematch around the corner, hopefully after a bit of time to recuperate, his mind raced to formulate a strategy against the equine she-devil.

He wasn’t sure how he’d succeed in the herculean endeavor, since he was likely stuck as a femboy for the better part of a day, though he felt sure there had to be a way. Depraved mare or not, Leech certainly had some sort of weakness he could exploit - it was only a matter of finding out what it was and how best to utilize it. He wasn’t opposed to stooping to something underhanded, if nothing else, yet he couldn’t rightly say how. Resigning himself to wait and buy time to think, he stewed on how best to best his amorous adversary…
