A Cunning Linguist

Adjusting her backpack, Leech trotted towards the edge of town. Normally, her trusty satchel would have been large enough to carry anything she’d need, although this wasn’t a usual day for her. A small cooler was stowed in her pack, along with a few other items. Thankfully, her cargo wasn’t too heavy, but it was a bit cumbersome. She just hoped she could find Mlem’s place before her cargo got too uncomfortable.

A couple of days ago, the slender unicorn had received a letter from the large, what-is-it pony creature she’d befriended. Well, actually, “letter” may be a bit of a stretch; in truth, it was more of a crude map, scrawled on a piece of parchment. Beside a simplistic drawing of the town, in the woodlands to the south, had been scrawled a little house; right next to what she assumed was a self portrait of Mlem.

Considering it had been some time since she’d seen the big lug, she decided to pay him a visit. She could only assume the correspondence was an invitation of sorts, since the depiction of the hybrid creature had a doodled smile on his face. Since Tekky was “working”, an endearing term used to describe sleeping while waiting for a batch of potions to stew, she figured she’d give her imposing friend a visit, but not before getting him a gift.

On her trek through town, she acquire a few select items. First, she’d purchased a dry erase board, given that the guy couldn’t verbally communicate; well, no, maybe he could, although if he had some spoken language, Leech sure as hell didn’t know what it was. Her second stop had been at the local creamery, to fetch the guy some gelato. He’d shown an affinity for ice cream before, when they’d first met, so she was positive he’d enjoy the treat. With her provisions safely stowed away, she set off on her little adventure.

Passing through the city’s outskirts, Leech glanced down at the map. There was no way to tell how accurate the thing was, since nothing seemed to scale, although Mlem’s place appeared to be less than a mile into the forest. It wasn’t like she was uncomfortable traveling alone, since she’d been doing it for most of her life, yet going through the wilderness wasn’t exactly her forte.

Forging ahead, through the underbrush of the woods, she winced. It was bad enough that she didn’t have any appropriate clothing for the journey, but the rough terrain wasn’t taking it easy on her either. Still, she persisted, pressing onward. If there was one thing she’d learned over the years, it was that friends weren’t the easiest thing to come by, and that they tended to be worth the effort of upkeep.

“Mlem?” Leech shouted, taking a breather by an oak.

She’d been hiking for nearly twenty minutes, yet she hadn’t seen hide nor hair of the big bastard. Looking around, she surveyed the landscape. If he really was living out here, she was pretty sure he didn’t have any of the typical amenities of modern homes, which made her think. Truthfully, she knew next to nothing about him, besides the fact that he was pretty friendly and of some species she’d never seen before.

“Mleeeeeeeeeeem!” she yelled, hoping that he was within earshot. Waiting a moment, and going without a reply, she silently cursed. The sun was already starting to dip over the horizon, leaving her with only a few hours left of daylight. If she didn’t find him soon, she was going to have to turn back.

Passing through a thicket, swatting the leaves and brambles out of her way, Leech was suddenly blindsided by something massive. Whatever it was was big and uncannily quiet, so she was caught completely unawares. A string of expletives escaped her, as she was hefted into the air. Glancing down, on the cusp of shitting her skirt, she saw a familiar face.

Peering up at her at her, just above a terrifying, tooth filled maw, was a pair of brilliant emerald eyes. Surrounded by a cream colored coat, punctuated by greens and rust-reds, the monstrous visage was but a scant few inches from her face. Its lower jaw split in a grin, just before its mandibles folded outward in a nightmarish smile.

“Mlem!” Leech exclaimed, beaming down at him. Wriggling out of his grasp, wrapped her arms around his torso, giving him the closest thing to a bear hug as she could manage.

Markedly taller than virtually any pony she’d ever seen, he towered over her. Beyond his impressive size, he was strikingly well built. With a gentleness belying his monumental physique, he returned her embrace. Mlem was the embodiment of the old adage “don’t judge a book by its cover”.

“Where’ve you been hiding, you big bastard?” Leech chuckled, lightly punching his arm.

Excitedly, and without warning, Mlem grabbed her hand and pointed towards some unseen destination. Noting the mare’s confusion, he rolled his eyes. After pointing to his chest, he made a cradling motion, before waving for her to follow.

“Is that where your house is?” she asked, cocking an eyebrow. At that, he nodded and gave her hand a tug. “Alright, lead the way.”

With that, the two were off. Honestly, she was glad to see him, especially after having marched through the damn woods by her lonesome. Having someone to travel with, even if they were functionally mute, was better than having no company at all. As they strolled through the brush, Leech was left to wonder what sort of home he had.

From what she could tell, Mlem was rather technologically primitive, seeing as how she’d only ever seen him wearing a simple loin cloth and nothing else. Not that she was complaining, since the meager garment gave her a superb view of his sculpted rump and thighs. Walking along, she watched his muscles glide over one another - that was, until he slowed. Looking up, she realized he’d noticed her admiring gaze.

“What?! Can’t a girl appreciate a dude?!” Leech bleated, scrunching her snout. Be damned if she couldn’t ogle an attractive guy here or there.

At her outburst, Mlem came to a halt and wheeled around. Judging from his knitted brow and stern expression, he wasn’t all to pleased, which caused the mare to gulp. Before she could apologize, he was upon her, grabbing her wrists and moving them above her head. Slowly, his lower jaw split, as a trio of tendrils wormed out of his face.

“Look, I didn’t mean anything by it!” she squawked, feeling herself get lifted into the air.

Stepping forward, the stallion - if he could be called that - pressed Leech against a tree. Just as she went to protest, two of his tongues started caressing her bosoms, while he pressed his snout to her abdomen. His breath was hot and bestial upon her belly, a mere hand-span from her loin.

As unsettling as the abrupt development was, she couldn’t help but be slightly turned on. Cursing her lewd nature, she gasped, as her nipples being caressed. Just as her heart started to race, he set her down and turned his back on her, nonchalantly continuing his walk, as if nothing had happened at all. Askance, the unicorn watched him depart.

“Seriously?!? You’re seriously gonna pull that sort of thing then just leave?!” Leech angrily groused, keenly aware of her moistened thong.

Without skipping a beat, Mlem looked over his shoulder and shot her a wink. Yeah, there was no doubt, the cheeky bastard had intended to get her worked up. Not that she minded, though she hadn’t been expecting any sort of lustful playing that early in her visit. Re-adjusting her pack, she stormed after him.

It wasn’t long before the two reached a pair of boulders leaning against one another. Between them was a hollow, leading into the earth. Turning to face his guest, Mlem gave a small bow and gestured towards the opening, silently urging Leech to enter. Sure enough, it appeared that his home was, shall we say, unconventional.

Stepping inside her host’s lair, Leech had to admit, Mlem’s accommodations were rather comfortable. She could best describe his home as a den; a single, large room with everything he would need. A few hides sat in the corner, just besides a straw mattress, and next to a neat little pile of comic books. She presumed he used the restroom outdoors, likely bathing in a stream or spring, since she didn’t see a bathroom. All in all, it was cozy.

“Gotta say, these aren’t bad digs,” Leech noted, hearing the monstrous pony plod up behind her. Feeling her pack shift, she wheeled around to find him fiddling with one of the straps. “No peeking!” she chirped, being reminded that she’d brought a gift for him.

Mlem cocked his head to the side, studying her for a moment. The unicorn simply smiled at him, while she shrugged the pack from her shoulders. Glancing up at him, she was reminded of just how different he was. He really did have several canine characteristics, namely involving some of his expressions and movements, and the weird tongue things were like something out of a Sci-Fi movie.

“Alright, so, first of all,” she began, squatting down digging out the tiny cooler, “I brought you this.” Handing it to him, he opened the small container.

Mlem’s eyes immediately alight, as he spied the frozen gelato within. Rushing off to the corner, he retrieved a spoon from within a crate stashed there and set upon the frozen treat. Watching him eat was interesting, as well as slightly arousing. His trifecta of tongues were a dervish, lapping and licking at the desert like there was no tomorrow.

“Hold your horses, there’s more,” Leech continued. Pulling out a miniature whiteboard, along with a handful of markers, she presented her second present. “I know it’s not that big, but maybe you could use it in town; ya know, because you’re not much of a talker,” she explained. The confused look on his face spoke volumes, so she decided a demonstration was in order.

Uncapping one of the markers, Leech did her best to sketch a picture of the two of them. Sticking her tongue out in concentration, she furiously scribbled upon the surface. Unfortunately, the final product wasn’t much more than a crude set of stick figures, with one sporting a pair of knockers, but at least she got the colors right. Showing it to him, Mlem smiled from ear to ear.

“See, you can write or draw on it, erase it, then use it again,” she commented, using her palm to wipe the board clean.

Shockingly, Mlem dropped the ice cream and rushed over. He bore a pained expression, as if wounded. Snatching up the board, he pointed to himself, her, then back to the white slate. Seeing the perplexed look on her face, he took her hand, still holding one of the markers, and brought it back to the little tablet. Clearly, he’d preferred her art to stay on it.

“Ok, ok! Jeez, I can do it again!” Leech grumbled, feeling guilty for upsetting the guy. It didn’t take her long to recreate the simplistic art, which appeared to appease him.

Taking it towards his bed, Mlem placed it besides his comics, proudly displaying the drawing she’d made for him. Satisfied with its placement, he extracted a journal from within his stack of literature, before returning to her. Proudly, he presented the book to her.

“What’ve you got here?” the mare thought aloud, flipping the small tome open. To her amazement, each page was littered with drawings. While none of them smacked of an artistic genius, it was clear that Mlem had an interest in illustration. “You know, a lot of these are cute,” she chuckled, stopping at a crude rendition of herself.

Flipping to another page, Leech noticed a self portrait of him. Above the caricature, the word ‘Non-Toxic’ was scrawled, leaving her to wonder. “Wait, is that really your name?” she inquired, peering up at him. He nodded, hitching a thumb towards his chest. “Huh...But you don’t mind me calling you Mlem?” she pressed, leaving him to shake his head. Turning her attention back to his journal, she resigned herself to continue using his nickname, until she could devise some fitting contraction of his actual moniker.

The sensation of digits through her mane caused Leech to look back upward. Standing just beside her, Mlem grinned down at her. Despite his looks, he really was a sweet guy, and affectionate to boot. As she went to go back to her browsing, her gaze passed over his loincloth.

Positioned as they were, her face was less at eye level with his crotch. Peering at the flap of leather, she was reminded of his unusual equipment. From her past experience with him, she knew exactly what was lurking just out of view, which sparked an idea. If he could brazenly taunt her, like he had in the woods, she saw no reason she couldn’t do likewise.

Wrapping her arms around Mlem’s thighs, she pressed her face against the thin garment. Breathing deeply, her nostrils were filled by his scent, causing a shiver to run up her spine. Over the aroma of the leather fabric, his musk shone through. Earthy, pungent, and primal, it was the fragrance of a dominant male, markedly different than that of a dickmare.

“Since I brought you a present,” Leech sighed, feeling the heat of his nethers through the cloth, “do you have something for me?” Peering up at him, she shot him an expectant look.

Mlem gazed down at her for a moment, before furrowing his brow. Looking to the ceiling, he thoughtfully rubbed his chin, as if to ponder her question. The sassy bastard was fucking with her again! Even though he couldn’t speak, and he lived in a cozy cavern, there was no way in hell he was that oblivious.

Leech impatiently strummed her fingers against his leg, while she awaited his reply. After a second, her composure broke. Worming her head under the loincloth, her suspicions were realized, as she found her face pressed against his semi-erect tool. Under his garb, his odor was overpowering, causing her pulse to quicken.

Coyness be damned, she wanted some dick, so she was damn well going to get it. His equipment was, like the rest of him; unique, a curious hybrid of canid and equine traits. Long, deep purple, and with a knotted base, it hung above a pair of swollen, furry testes, each the size of a large citrus fruit. Without preamble, like some wanton harlot, she dragged her tongue up its length.

As the salty, sharp flavors of his unwashed member bathed her tongue, Leech’s head began to spin. Between the heady smell and irresistible taste, she could already feel herself getting wet. Getting plowed by a well hung mare was all well and good, but males had a certain je ne sais quoi that women lacked. She barely noticed as his fingers ran through her mane, as he pressed her to himself.

‘Fuck, I could get addicted to this,’ Leech thought, slipping the tapered tip of him past her lips.

Adjusting herself, shifting to fully face him, she splayed her legs. While her right hand fondled Mlem’s ripe and succulent nuts, her left snaked under her skirt, where she eagerly started massaging her marehood. It was only a matter of time until she got stuffed with the puppy, so she did her best to get warmed up.

Undoing the string affixing the garment to his waist, Mlem let his sole piece of apparel fall to the floor. It wasn’t hampering Leech’s activities, as far as he could tell, yet he wanted to get a decent view of her slobbering on his prick. As she was unveiled, he noticed she was already playing with herself; with that in mind, he unhinged his jaw…

Given her view consisted of Mlem’s abdomen, junk, and upper thighs, Leech had no way of knowing what she was in for. The first sign that something was off was a slithering sensation down her back, beneath her top. The second, far more troubling indicator was when she felt her skirt being tugged at. Glancing down, realizing what was happening, she raised her arms, just in time for her host to…

With the dexterity of a randy octopus, Mlem disrobed Leech in a multi-pronged attack. Her skirt and panties were hauled down her legs, while her blouse was pulled up and over her head. He couldn’t help but smile at the fact that he’s successfully stripped her in an instant. Peering at one another, and both grinning like idiots, the two chuckled. Now both fully nude, taking one step closer to doing the do, he gingerly pressed his junk against her face.

Saliva and pre-cum smeared over her cheek, as she lovingly nuzzled his tool. Leech gave the head of his shaft a kiss, before virtually inhaling half his cock. Over the years, she’d developed a bit of a penchant for oral, so she knew exactly how much she could fit in her gob. Savoring his warm, velvety flesh against her tongue; she slowly retracted her head, dragging her lips along its length, as she started to blow him.

Admiring the sight of the unicorn skillfully servicing him, Mlem took a moment to enjoy the sensation. Most mares ran from him, and there was even one time where a girl fainted after seeing him, but Leech was different. He considered her a dear friend, especially given the circumstances under which they’d met.

She’d never looked at him with scorn or animosity, having gone so far as to unquestioningly help him on his first trip into town; as such, she held high favor with him. Bearing that in mind, he couldn’t just stand there and let her pleasure him unmolested. Gradually, the tendrils from his maw crept behind her, sluggishly moving to her rear.

Leech groaned around the meaty appendage, as she felt herself penetrated by one of Mlem’s tongues. The first, buried in her snatch, was quickly joined by a second, while a third wriggled into her ass. Thankfully, having anticipated some sort of indecent activities transpiring, she’d taken care to thoroughly clean all her nooks and crannies. Taking a deep breath, and appreciating her partner’s efforts, she relaxed her throat and crammed a few more inches of him into her snout.

Pistoning two of his muscular tentacles into her snatch, while the third delved into her tush, Mlem caressed her hair. It was quite a sight, watching her bob her head back and forth, only eclipsed by the snug sensations of her esophagus. A deep purr escaped him, as he gently began bucking his hips.

With her partner gently humping her face, Leech hummed around his dong. There was no way she’d be able to hilt him in her muzzle, although that wasn’t a terrible problem. No, there were other, far more accommodating portions of her person that could sheath his mighty member. Since his tongues were doing a more than capable job of working her holes, she moved her hands to her chest, where she pinched and gingerly twisted her nipples.

The mare’s soft gagging noises filled the air, as Mlem tenderly plowed her face. It felt great, and was an exquisite sight, but he wanted to fully submerge himself within her. With his lust mounting, he withdrew his tendrils from her loin. Wrapping one prehensile organ around each of her legs, he lifted her up and away from himself. As she turned, his eyes locked upon her rear.

With her fellatio unexpectedly interrupted, Leech gasped. Being hefted from the ground and spun around, she could guess what was coming. As much as she wouldn’t mind getting a cunt full of Mlem’s fat fuck-stuck, she had plans of her own. Waving frantically and kicking her legs, she did her best to get away.

“Wait, damn it, I got something I wanna try!” she barked. Fortunately, Mlem slowly lowered her to the floor and released her. Judging from his scrunched snout, turgid length, and tapping foot, he wasn’t pleased with the disruption.

Scampering to her bag, Leech swiftly grabbed her final present for the chimeric stallion. Pulling out a mass of connected leather bands, she presented the tangled bundle to her host. If Mlem knew what it was, he gave no sign; impassively studied it for a moment, before giving a shrug. Rolling her eyes, she walked closer to him.

“Get on your knees really quick. Trust me, if you don’t love this, I’ll let you do whatever you want to me,” she chuckled.

Mlem, looking more than a little curious, acquiesced. Sinking to the floor, Leech scurried to his side, as she untangled the odd mass. Slipping his arms through two of the bands, she secured various segments over his chest and behind his back. The entire operation took less than a minute, leaving the unicorn to smugly appraise her work. Nodding to herself, pleased with her efforts, she strolled back around to face him.

“Right, big boy,” she purred, tracing designs over his abs, “time to test this out.”

Mlem glanced down, trying to figure out what the mare was doing. It wasn’t until she pressed her back against his chest, reached up, and grabbed ahold of two bands over his pecs, that he realized what she’d done. The harness would, if he had to guess, allow him to fuck her while he stood, effectively giving her a means of riding him in an upright position. With a grin, he stooped down, grabbed her hips, and brought her into the air.

The sensation of being effortlessly lifted was odd, but that wasn’t what had Leech’s attention. Peeking down, she observed Mlem’s titanic tool appear from between her thighs. Spreading her legs, while holding tightly to his harness, she readied herself. Her eyelids fluttered, as the spear-like head of his cock penetrated her. Inch by inch, she was lowered onto it, incrementally spreading her marehood further and further, until she rested on its bulbous base.

Giving her a second to adjust, Mlem began steadily rutting her. The mare’s silken interior embraced his length, clinging to it on the backstrokes and relaxing on the thrusts. Every motion sent the tip of his member to her womb, teasing the inner entrance. While he tried to be gentle with her, given their differences in mass and strength, it was still more than many females could bear; luckily, she didn’t mind.

“So,” she cooed, “I hope you like the ki-OH FUCK!” Whatever she had intended on saying died, as Mlem started plowing her from behind.

Standing upright, he firmly held her waist, while he thrust into her. Since he was so much larger than her, Mlem saw no reason not to use her like a sex toy. Besides, given how she was mewling, she was loving it. Pulling her to himself, as he bucked his hips forward, he glanced down at her face.

Noticing his attention, Leech momentarily freed one hand to reach up and stroke his cheek. “Kiss me you big - Mmmmph!” For the second time in rapid succession, she was cut off; only this time, the cause was more direct.

Upon hearing her request, all three of Mlem’s tongues shot into her mouth. As a rather seasoned kisser, Leech thought it would be a nice, sensual addition to the moment; needless to say, she was woefully mistaken. As the trifecta of tendrils squirmed over his lips and gums, they drove themselves deeper and deeper, until they eventually worked their way into her esophagus.

She could breath, but only just, so she wasn’t immediately concerned about asphyxiating. Holding onto his harness for dear life, the tentacles plunged down her throat. As a mare who’d deepthroated a fair number of creatures before, nothing came close to the squirmy-wormy sensation of a trio of tendrils in her stomach. Throughout it all, his efforts at rutting her didn’t relent in the slightest.

Taking care to hold her close, should she lose her grip, Mlem pounded her cunt. Every thrust caused his knot to grind against her entrance, teasing him with the prospect of fully hilting himself. With his tongues working through her guts, slinking into her large intestines, he moved a hand around to her crotch. Maybe if he just…

The sensation of a large finger massaging her clit caused Leech to writhe and gag. Sex was one thing, but this was some sort of circus act of depravity, not that she was complaining. With everything going on, she was completely and utterly at his mercy. There had to be at least a dozen feet of serpent-like tongue working through her insides, not to mention the massive dick hammering her snatch.

Fully erect, his equipment stood at just a shade over a foot, but the base was an absolute bastard. Before a climax, it was about the size of a grapefruit, but it got even bigger once he busted a nut, effectively locking him to his partner. With few other options to reciprocate his actions, she clamped down around him, urging him for more. Since he’d knotted her before, she wouldn’t be satisfied until he did so again.

Emboldened by Leech’s enthusiasm, Mlem leapt to action. Pressing her snout against hers, burrowing every inch of his tongues into her maw, he kissed her deeper than any creature ever had. Locked in her embrace, he rammed his hips forward, while vehemently pulling her to himself. With the powerful move, her cunt eventually relented, allowing his knot to pop into her.

An incoherent gurgle left Leech’s tongue filled lips, as she spontaneously orgasmed. With everything that was going on, having a massive bulb of flesh smash against her g-spot sent her over the edge. Her marehood spasmed, seizing around the base of his tool, as it squirted nectar to the floor. Her mind barely registered that he hadn’t stopped moving, nor that the head of his dick was now lodged in her cervix, so she didn’t notice him picking up speed.

The unicorn’s quivering body and vice-like snatch only spurred Mlem to fuck her harder. Truth be told, he hadn’t gotten any action since their last encounter, so he’d been aching to see Leech again. Now tied to her, his movements were limited, but he kept thrusting away. As his knot slowly expanded, locking into place, his balls pulled up to his groin.

Though Leech had just cum, another climax was quickly approaching. Every part of her was being violated, even the bits that were never meant to be caressed by another. Just as some modicum of sanity began to return, the trio of tentacles emerged from her ass; as fate would have it, it was the very moment Mlem began to unload into her.

Breathing hotly into Leech’s mouth, he held her tightly to his body. His legs trembled, threatening to buckle, yet he remained standing. Pints - nay - liters of spunk erupted into Leech’s womb, coating her interior in the scalding, gooey substance. Her eyes rolled around like mad, as her body coped in the only way it knew how - by sending her into a maelstrom of rapturous chaos.

The sheer intensity of it all was mind bending, surely enough to threaten the sanity of a great many. Honestly, Leech couldn’t say what had happened, considering she blacked out at some point. The last thing she remembered was her arms and head hanging limp, as she drunkenly gazed down at her distended belly.

Mercifully, Mlem took note of her plight. He hadn’t intended to fuck her into a coma, yet it had happened regardless. Unsteadily, he plodded over to his bed, while keeping her held against his chest. Retracting his tongues, all twenty some-odd feet of them, he let her breathe freely. Easing himself to the mattress, and noticing the sun had set, he curled up around her.

Considering they’d likely be knotted for the better part of an hour, and that she had passed out, there was nothing better to do. Wrapping his arms around her, lovingly stroking her mane, he kept her warm. Peering over her shoulder, at the little drawing she’d made of them, he smiled. Yeah, he was glad he’d moved closer to town...
