Postal Passions: 5 - Special Delivery

Lying on her back soaked by both the storm and her own seemingly unending sexual secretions, Postage Due was aroused beyond all measure. And terrified beyond belief.

Bowled backwards by the massive magical force of the unicorn climax, which had been somehow strong enough to knock out or even outright destroy the firegem lights within fifty yards of them, she found her body tingling fiercely, echoing with the same orgasmic pleasure she could only guess that Certified Mail himself had experienced.

She even swore she had a male organ for a moment, buried impossibly deep within his eagless lover, wrapped tightly by her inner walls whose movements she could feel quite keenly as the contents of his apples were emptied within her.

It was like nothing she’d ever felt or dreamed she could feel, and it had happened all by accident! Is… THAT what it feels like for guys…? she thought in great wonder as her senses gradually returned and the sensations slowly dissipated, to her great disappointment, leaving her grasping at a nonexistent stallionhood that her overloaded senses told her had been there.

She’d heard of such things happening in rare instances—unicorns involuntarily broadcasting their sexual pleasure to others, making nearby ponies feel everything they did. But by all accounts, it was an exceptionally uncommon event; something that only happened for extremely passionate encounters that boosted their mating magic far beyond anything they were normally capable of.

Such thoughts only dimly registered on her mind, however, as she basked in their borrowed afterglow for a moment, magic still all but radiating off the pair like a slowly fading ember. She’d just seen Owlia start to fall over before the lights went out and she got knocked on her back, and for a moment, she couldn’t see or hear anything from them as the storm picked up again, the wind and rain increasing.

“G-guys…?” she called out tentatively through it, trying but failing to stand around the flared wings that pinned her to the ground. Between the falling rain, which seemed to do anything but cool her off, and after all she had just experienced, she was still incredibly turned on, her marehood facing the scene and drooling a steady stream of honey onto the cobblestones below.

She even worried her own stallion would never be good enough for her again after the interspecies encounter she’d just witnessed; finding herself with an enormous interest in griffons for how passionate and powerful Owlia was.

M-maybe I could bed one of the Griffon Express couriers…? The disjointed thought crossed her mind despite the fact she was happily in a herd, only for the idea to be cut short by a low and dangerous growl ; a predatory sound that froze her very blood as she watched the shadowy form of Owlia Accipiter rise anew, pushing up off the ground.

At that moment, the storefront lights across the street flickered back on, followed by the next-nearest street lamps, slowly shaking off the magical surge which had disrupted them. And in their low light, Postage Due saw not the familiar form of her griffon friend, or the feathered wings of an eagless.

She instead saw the ominous outline of two enormous bat-wings flared to either side of a pitch-black creature at least a third larger than Owlia, visible only as a silhouette with two large cat-slitted eyes, the orange-glowing gaze boring directly into hers, something both hungry and heady in her gaze.

“So, did you like what you saw, Postage Due?” A voice that was Owlia’s but not rumbled huskily; the pegasus mare could just make out the glimmer of a long, wet tongue as it licked around her longer beak and a glint of something long pointed directly at her. “You know, it seems a shame for you to just lie there watching… wouldn’t you say, C-M?”

Lightning flashed again at just that moment, illuminating her bat-winged form fully for a bare second, showing that Owlia’s formerly brown-and-white coat was now head-to-toe dark, as she still sat straddled atop Certified Mail, his stallionhood now hanging in front of her in a heavily altered form, looking not just longer but far more tapered with an odd bulge at its base.

The front office lights of the post office then clicked back on, and Postage Due gasped and gaped as she realized her perspective was completely wrong, both her fear and excitement growing exponentially for it.

For she could see in the added light that Owlia was in fact stroking a massive griffon lionhood of her own, its tapered tip standing rigid over Certified Male’s chest and pointed right at her!

Owlia’s senses returned to her slowly, still feeling echoes of the pure rutting rapture she had just experienced.

Everything had gone topsy-turvy, as she’d heard ponies put it, the moment she had hit climax; one far more powerful than anything she had ever experienced in her life. None of the mating rounds she’d had in the past came even close to comparing to both it and the afterglow as she felt a massive wave of magic overtake her, transforming from her within.

She didn’t recognize the magic, nor immediately the form it imparted her as she slumped forward over Certified Mail; the only stallion of either species who had ever so turned her on. But she didn’t fight it either as she felt her body remake itself from the inside out even as it continued to be wracked by wave of wave of sheer pleasure. In the throes of her seemingly endless orgasm, she didn’t wish it to end, and she welcomed anything that added to it.

It was an effect she soon realized wasn’t limited to her as she felt the stallion shaft so deliciously deep inside her lengthening and expanding further, filling the increased space of her eagless opening and inner nest just as quickly as it was created. Her spine stretched, her limbs lengthened, and even her claws and talons suddenly turned more predatory as she regained just enough of her senses to push back up off the ground, opening her eyes to see them.

She only barely bit back a gasp at what she beheld; long dark-feathered limbs that trailed off into gleaming black talons. In fact, she could see everything clearly in the near-pitch blackness that Certified Mail’s climax had left the street in, including the gaping form of Postage Due, who was lying on her back ten feet away.

“G-guys?” she called out tentatively, both her fear and her ongoing excitement obvious to Owlia from her pair of very hard teats and the thicker fluid that coated her hoof and marehood, matting her inner thighs and tail.

Still trying to gather herself, Owlia didn’t respond right away. Her wings had finally gone slack, but as sexual excitement swiftly reclaimed her again—Certified Mail hadn’t softened at all inside of her; she didn’t feel complete without him filling her now!—and even stronger than before, her slightly slackened wings quickly flared back to their full dimensions.

It was only then the former griffon eagless noted her newly night-blue headfeathers and large bat-wings; her fur turned equally dark on her hindquarters. And that was to say nothing of the large lionhood and pair of equally impressive supporting seed-producing orbs in her lap, resting on Certified Mail’s belly. The latter quickly engorged; she could all but feel them swelling with seed while the former quickly surged to full erection for the first time. It rapidly reached dimensions far beyond anything she’d seen from a griffon before, surpassing eight, then ten, then even fourteen inches in length!

At first, Owlia could only stare at her new male attribute in wonder. This… is... MINE…? She reached down to grasp the unfamiliar organ and begin stroking it with a low growl of pleasure, amazed at the surge of sensations that flowed from the male shaft, admiring its form, from the vaselike bulb at its base—typical of her race—to the more tapered feline tip that should instantly sensed would allow her to quickly and easily penetrate any partner, gaining initial entry and probing their depths while her bulb pried them open more fully.

It was beautiful. Her wings and new form were beautiful. And he was beautiful to her, her eyes recognizing his newly thestral features and longer horn, bracketed by two tufted ears. He didn’t have wings, but she didn’t care—his horn, his love, and his stallion shaft were all she needed from him.

Which was not to say there weren’t other things she wanted, she realized as she turned her gaze on their audience, suddenly sizing her up as both prey and a new target of her passions.

“So, did you like what you saw, Postage Due?” she asked with a suggestive growl as her new eyes devoured the pegasus mare’s furred and feathered form. She gave her beak a languid lick with her longer tongue—which her beak had apparently lengthened as well to accommodate—as she wondered what scent and flavor her coworker’s marehood was.

“Seems a shame for you to just lie there watching … wouldn’t you say, C-M?” She milked her own shaft to watch the other mare’s reaction, seeing clearly her eyes go wider as the lights from the post office entry came on again, at least partially illuminating them enough for Postage Due to realize what she had and what she was doing; her breath catching at the sight and her eyes suddenly fixed on it, taking in its exotic shape and impressive size.

But Certified Mail, as he always had, showed no interest in his subordinate, keeping his eyes fixed on Owlia, drinking in her altered form and new male attributes, which he shortly started to stroke with his reactivated aura.

“She ain’t my type—only you are, Owlia! But still, I can hardly blame her—I might have accidentally broadcast what I was feeling to her, just to let her know what she and other mares never did for me!” he explained with a smirk from his back as his enhanced horn reignited to begin stimulating her, not even remotely troubled that he was caressing and manipulating a male organ.

He’d never been into stallions or stallionhoods, but the fact that this one belonged to her changed everything!

“Oh, really?” Owlia said in amusement as she began to lightly piston her hips again on top of him, feeling a renewed surge of sensations start to return at double even the incredible intensity of before, the pumping action of her hindquarters working some spunk out of the tip of her new lionhood for the first time. “I’m flattered. And honored!” she offered between fresh pants in return as she offered her new organ to him fully, arching her back again with a startled hiss—a thestral sound—as he began to lick it, sampling its seed and licking his muzzle happily at the taste.

“You should be, my beloved Owlia. You’re like no female I’ve ever known! Still, as far as Postage Due goes, she never did have any respect for personal boundaries… and some disciplinary action must be taken!” He got an evil grin as his mating aura reactivated at triple its previous strength, bathing the peagsus mare and half the otherwise storm-emptied street in its brilliance.

Postage Due instantly responded with flushed cheeks and a fresh surge of blood to her flight anatomy and femininity. “B-but…” she protested mildly as her wings splayed harder and hoof migrated towards her marehood again as she found her gaze this time fixed on him; his larger size and longer horn making him look like—and perhaps even as powerful as—the Highborne thestralcorn priests of old.

“Pl-please…” she begged as she began grinding her hoof into her overheating marehood only to find her own efforts could grant her no relief.

“So was it good for you, Postage Due?” he repeated her words to him from earlier that night as he magically lowered Owlia’s organ to his lips and began laying a fresh trail of licks and kisses on it, causing her to throw back her head and moan, rewarded by the bat-eagless beginning to work her hips up and down on him harder. “Not that anyone asked you…”

“I’m asking…” Owlia corrected breathlessly, her bat-wings growing rigid to the point that the membrane between her wing digits audibly stretched, sending a ripple of pure rapture through her. “Sh-she was watching us the whole time! And I loved it!”

“So I noticed…” Certified Mail turned breathless again as he began thrusting up to meet her, the base of his organ just visible as he accented his physical efforts by lifting her up magically, then pulling her back down on him, causing her new lionhood to visibly pulse with each effort. It drizzled a steady stream of her new seed onto his muzzle, which he lapped up eagerly, working lovingly on the head of her new shaft with his mouth and magic. “But like I said, she never respects privacy or personal boundaries! I meant what I said about punishing her! So…”

His horn flared anew with an additional spell, and suddenly Postage Due found herself feeling all he did again, but with a far stronger effect as he broadcast his sexual pleasure to her deliberately this time!

“W-wha?” she called out in shock as Certified Mail’s magic forcibly fed her a steady stream of his own sensations as he took the half-thestral eagless again from below, letting her ride him while sitting over him, orally and magically pleasuring the last half of her new lionhood for good measure.

“But… that’s…” Postage Due whimpered helplessly at the sensations he was feeding her, letting her know directly how incredibly good it felt for a stallion to take an eagless; his sensual spellcasting so powerful and thorough it made her feel that she was him! And yet, far from cathartic, it was near-torture to her as she repeatedly grasped futily at the phantom organ she could feel between her legs, desperate to feel it; to stroke it—to help relieve the fire and fullness she felt within it!

But despite all her senses telling her it was there, and despite all her instinctive attempts to thrust it deeper into the exquisite eagless she could feel straddling her, the mare’s bucking hips had no effect. And worse, she continually grasped only air when she tried to touch it and found herself a helpless slave to Certified Mail’s pleasure for it, leaving her only wanting to curl into a fetal position and clop, keeping her eyes tightly shut to try to restrict her stimulation.

But her flared and arousal-paralyzed wings would not allow her to do so, keeping her on her back, and what self-stimulation she could manage brought her no relief. She could feel every inch of his now-sixteen inch organ sunk to the hilt within Owlia and feel his flaring head once again invading her very womb; feel her muscles milking him expertly, massaging and stimulating him to the point that she thought she might go mad if the pure passion and pleasure she felt from him got any stronger.

But heedless to her limits and tearful pleas to let her go, it did, leaving her ever-more desperate for a release only the rutting half-thestral pony/griffon pair could now grant.

Whatever nightmare-fueled sexual creatures the two had become, they were now able to reach levels of sheer sensual bliss and ecstasy far beyond anything Postage Due had ever experienced or even thought possible. She could only writhe on the ground before them, all but sobbing at the intense elation and pure rapture she was being forcibly fed.

Her aching sex and very psyche wracked by the borrowed bliss, she realized then that neither her stallion nor her herd mares would ever be able to satisfy her afer this.

That indeed, no pony at all would ever be good enough for her again!

There’s nopony left for me now… except THESE two! Lost in pure lust and the unending assault on her senses and sanity from their lovemaking, she considered leaving her stallion and marrying Certified Mail and Owlia Accipiter instead, hoping and praying the powerful and incredibly beautiful and desirable bat-eagless would be willing to join a pony herd.

Please, C-M! Accept me! TAKE me! She silently begged him, praying Certified Mail could hear the thoughts she was then incapable of voicing. I’ll do whatever you WANT! You can have me whenever YOU want! I’ll have your foals—and HERS! she offered to him desperately, suddenly imagining her eagless stallionhood—an idea she never even dreamt was possible!—driven deep within her. She had no idea if he had heard her, finding her eyes opening again to take in the mating pair to whom she was now irrevocably joined and bound with, wondering when her sensual torment would finally end even as she prayed it wouldn’t.

“My love?” Certified Mail spoke up after what seemed like a small eternity. “I’m close again…” he announced as Postage Due felt magic and energy surging to his horn and stallionhood; his apples starting to retract to release their precious cargo and his body tensing like an ocean wave drawing in before breaking.

“Me too…” Owlia confirmed as Postage Due prayed the coming climax wouldn’t break her, watching the eagless now feverishly stroking herself with both sets of talons. “Give it all to me! And to her!” she hastily added as she set her glazed but slitted orange-glowing eyes on Postage Due yet again, aiming her new organ right at her as her body tensed hard.

“Here it comes, marefriend! Special Delivery from the Griffon... Express...!” Owlia’s words escalated to halfway between a lion roar and an avian shriek as her leonine stallionhood erupted hard, showering the pegasus mare with her newly minted seed. The first bursts hit her chest and head, her muzzle automatically falling open to receive it just as Certified Mail’s own climax hit, the fed orgasm triggering the pegasus mare’s in turn.

“Ah! Yes! Yes! Take it ALL, my exotic and erotic eagless!”Postage Due exactly echoed Certified Mail’s climactic shout, involuntarily bucking her hips again in time with his as she felt him deliver his stallion seed deep into her beautiful and blissful bat-eagless body once more. Her connection to him was so complete she stretched out her neck as if to help release the accumulated mating magic from her nonexistent horn, which she also felt erupt with a series of extraordinarily powerful and enjoyable orgasmic pulses that wracked her overtaxed mind and marehood.

Lost in the release of both his body and her own, she only dimly felt the splash of Owlia’s seed against her face, her chest, and then progressively further down her body, calling C-M’s name over and over. Despite that, the eagless retained enough awareness to shift her aim to Postage Due’s erogenous zones, coating her belly, teats and marehood in turn; even sparing a couple heavy spurts for her wings and flight muscles.

They tingled heavily with their new luster, twitching with fresh warmth and pure pleasure as Postage Due began to directly absorb the energy of the corruptive curse they contained.

The sheer amount Owlia generated was incredible, leaving it dripping off the pegasus mare; the magic it contained soaking quickly into her body from every point and angle as Postage Due collapsed to the ground in a daze. She could only lick weakly at her muzzle and paw feebly at her marehood as the imparted male climax--and her own--finally let go of her.

But its effects were just beginning, leaving her mind and body irrevocably altered as the exotic magics the curse contained began to take hold of her, causing her to grow fractionally and her senses to immediately enhance. As her eyes flickered back open, she could suddenly see and smell far more; every detail of their altered forms was now apparent to her newly slitted eyes even in the near-darkness while her nose twitched, picking up both the individual scents of her new lovers as well as the smell of the exotic eagless seed(!) that still covered her.

Her body involuntarily stretched to help the changes progress; her clit doubling in size and mammaries and marehood swelling; all her erogenous areas becoming far more sensitive as she gained two inches in height and a full stone of weight. Her wings also expanded, her flight muscles quivering as they added more sinew to accommodate their larger wingspan.

But from the outside, the changes were minor and she did not otherwise lose her pegasus form except for new cat-eyes, finally focusing them with great difficulty to find herself looking up into the altered, dark-feathered face of Owlia Accipiter, who was standing over her, staring down at her in happiness and hunger like the smaller female was both a partner and captured prey.

“Enjoy yourself, P-D?” she asked as Postage Due could only moan weakly, the rain only slowly washing off the residue of her love.

“I’d think so…” A smirking Certified Mail appeared at her side, rubbing shoulders with the large eagless and exchanging nips and nuzzles with her happily, his own enhanced features very much in evidence from his larger body to his longer horn to the tufted bat-ears. “She was begging us in her thoughts to herd her! Said she wanted my foals—and yours!”

“Oh really?” Owlia grinned as Postage Due could only reach weakly for them with a hoof. “Well, I guess we better get started, then!” she announced as she positioned herself before the mare, the tapered head of her new leonine stallionhood shortly pressing against her fellow mail worker’s wet, wide and very receptive opening.

She paused there to savor the moment, leaving a trembling Postage Due aware of its presence and anticipating its entry. “Pl-please…” she plead again, biting her lip hard. “Need this… need you!” she just managed to add.

Owlia smiled at that, licking her beak again. “Then you can have me, P-D. Both for being such a good friend and having asked me so nicely!” the bat-eagless announced as, helpfully guided by Certified Mail’s magic, she shifted forward and began to push her long lionhood inside.
