The daring explorer Kooshmeister, or "Koosh" to his friends, had penetrated deep into the trackless reaches of the jungle. The brown-furred male squirrel with red hair was wearing a pretty traditional explorer's outfit consisting of a pith helmet, a khaki-colored many-pocketed shirt, unbuttoned almost down to his belly button in concession to the heat, shorts, ankle boots and tall socks that came up to his knees, with a canteen and holstered pistol on his belt. Large, black-rimmed glasses adorned his muzzle, their lenses slightly fogged up from the tropical heat. In his hand he held a machete, with which he hacked at dense weeds and vines, fighting his way through the sweltering vegetation, pausing occasionally to push his glasses back up into place whenever they threatened to slide down off of his muzzle, wondering when the dense undergrowth was ever going to end... when suddenly it did. As he slashed through the final wall of plant life, he all but stumbled into a sudden clearing, where he came upon a most unusual sight.
 
In the middle of the glade with a wide and shallow lake with a roaring waterfall emptying into it, into which he'd wandered, was the most gorgeous reptilian creature he'd ever seen. With enormous hips and an impossibly long tail, the green-skinned male was stretched out on a large rock warming himself in the sun. He sat up and with feigned disinterest turned and looked at the bushy-tailed intruder into his domain.
 
"Greetings," he said in a low voice, just barely audible over the sound of the falls. He turned onto his side, giving the squirrel a nice view of his reptilian sheath and balls. "My friends call me 'Snake.' I'm a Rilvazen. This is my domain. Have you lost your way?" A forked tongue flicked out.
 
The squirrel shook his head, surprised at how forthcoming the reptile was being with someone who'd accidentally intruded into his domain. He had no idea what a Rilvazen was. Had he found a new species of sentient reptilians? "I was... just trying to penetrate deeper into the unknown than any explorer before me," he said, managing to find his voice. For emphasis, he held up the machete and used it to point back the way he'd come. "Or trying to, anyway."
 
That answer seemed to interest the reptile very much. "Well, I think I can help you with that." He sat up more fully, the head of his penis beginning to poke free from his sheath, which didn't escape Koosh's notice. "Shall I come to you, or would you like to come to me? Either way, I suggest you... disrobe."
 
"D-Disrobe?" the squirrel repeated, seeming uncertain, though he was already shrugging off his backpack.
 
"Yesss," came the hissing reply. "If you come to me, your clothes will get wet. If I come to you, they'll get muddy. No matter which option you choose, you don't want those nice explorer's clothes to get all filthy, would you?" He winked.
 
Koosh found that he couldn't argue with that. For one thing, it made sense. For another, there was something... persuasive and insistent in that voice. He stuck the machete into the earth at his feet so it stood with the wobbling handle completely upright, took off his pith helmet and then began undoing the few buttons that were secured on his mostly open shirt, stripping the garment off, exposing his bare chest to the Rilvazen, who seemed to like what he was seeing. Indeed, Snake was very pleased to see the squirrel beginning to undress, and he slid off the rock he'd been sunning himself on and waded serenely through the water as his "guest" unbuckled his belt, letting it drop to the ground heavily, the contents of the canteen sloshing, the gun still in its holster. He began fumbling with the zipper on his shorts.
 
"Tell you what. Meet me halfway. On the shore."
 
Watching the approaching creature, Koosh hurriedly stripped to his underwear, a pair of briefs that, to his embarrassment and the reptile's amusement, bulged forth with his arousal. When he stopped there and began to bend down towards his feet, Snake, concerned that the squirrel intended to leave his undergarment on, spoke up.
 
"All of it," he insisted.
 
"Y-You want me naked...?" Koosh asked, pausing halfway through untying his boot laces.
 
"Of course... you need to be naked in order to penetrate deep inside a Rilvazen." That thick reptilian cock grew forth further, dripping pre.
 
"P-Penetrate...?" The shivering rodent clumsily took off his briefs, his erect cock bobbing as he stepped into the warm water, which proved to be about knee-deep, and began wading through it towards his new companion. His helmet, clothes and equipment he left where he'd lain them, and they quickly left his mind, even the gun. Assuming he understood the reptile correctly, that wasn't quite the kind of exploring he'd had in mind when he first set off on this expedition, but who was he to say no to an offer of sex from such an enchanting creature? Besides, something about Snake's voice compelled him to obey. Reaching Snake, he moved up against the nude reptile. "What is a Rilvazen, exactly...?"
 
"It's what I am." That answer wasn't especially illuminating, but Koosh's curiosity was slowly leaving him, to be replaced by a lustful need which was soon to occupy all of his thoughts. "But if it helps... you can just call me Snake." That worked. After all, he'd said that's what his friends called him, and who was he but a new friend?
 
"Well, Snake," said the squirrel, "how are you going to help me?" He knew the answer. Knew what trail the reptile intended him to blaze, so to speak, but he asked anyway, just to keep talking. He liked talking to this creature.
 
Turning, Snake bent over, lifting his enormous tail, exposing his asshole to his new friend. "By helping you penetrate depths into uncharted territory. At least uncharted territory for you." He winked and flicked his tongue out, and then that monstrous tail whipped 'round and encircled the squirrel explorer's waist, dragging him forward until the tip of his cock touched Snake's anal opening. "Now, my friend... take me."
 
"Y-Yes..." gasped the explorer, and, gripping those enormous hips, bucked forward and plunged his cock, big and thick for his size and build but still tiny in comparison to the beast dangling between Snake's legs, into the tight and hot Rilvazen asshole. "Aahhhh! S-Snake... y-y-you're sooooo tight!" He moaned and his eyes rolled back in his head.
 
"You'll soon see how tight, my sweet," hissed the reptile, enjoying the feeling of a thick cock up his rear end, knowing that it wouldn't be all of the squirrel to go up there that day. "Lube me up good and proper."
 
And with that, Koosh began thrusting into Snake's rear, fucking him good and proper in front of that beautiful waterfall in the middle of the jungle, his mind racing, his thoughts a whirlwind of confusion, the excitement of the wonderful discovery he'd made and what it would mean for his academic career intertwined with just good this new trail he was blazing felt. Meanwhile, the Rilvazen he was plunging himself into knew the truth, that not only wasn't the explorer not blazing any new trails, but that he wouldn't be reporting back to anyone, or ever seen again, for that matter. But for now he simply enjoyed getting railed by the cute, big-dicked squirrel, stroking his own monstrous member.
 
With a passionate cry, they both came at the same time, their voices mingling. Koosh's thick jizz went up Snake's asshole. Snake's own seed spewed forth to coat his belly as well as splash noisily down into the water and float on the surface. His tail, which had been wrapped around the squirrel's waist, tightened and pulled him forwards, indicating he resume.
 
"Mmmmoooore," he groaned, wanting another go. He wanted his anal entrance lubed good and plenty, and the squirrel's load, though not meager in the slightest, just wouldn't do. Not yet.
 
The squirrel panted, unsure if he could continue, but something in the Rilvazen's voice made him obey, more than that, made him want to obey, to please his new friend, and again those hips began bucking. "Y-Yes..." he managed breathlessly. "Anything you say..."
 
"Yesss," Snake agreed, grinning as the fucking renewed, nimble fingers tightening around his own member once more, squeezing the last of the ejaculate out in a big glut of spewing spooge before starting to jack along its length. "Anything I say. Whatever I command, you'll do. Understand my little bushy-tailed morsel?"
 
That voice. So persuasive and dominant. The squirrel couldn't resist. He nodded, panting, tongue hanging out.
 
"I can't hear yoooooou," Snake teased his friend in a singsong voice, tightening the grip of his tail around him a little painfully.
 
"Aaghh! Y-Yes! I understand!"
 
"Good." The coils loosened but didn't release him.
 
It went on like this for some hours. Snake took it in stride, as he took everything in stride. Though his mind and body were wracked by pleasures few people would understand or ever even be able to experience, he kept his head, and his mind remained sharp and his body tense and ready, like a coiled spring, waiting for the right moment. It came shortly after Koosh did for what seemed like the tenth time. He felt a weight against his back. Something furry had collapsed against him. He felt hot breath against his shoulder blades. Grinning, he glanced back and saw the tuckered out rodent lying bent over along his bare back, glasses all but sliding off the tip of his muzzle, lenses fogged from the intense heat of their lovemaking. Were it not for the tail around his waist, the other male would collapse completely, so loose and weak were his legs from several hours of standing up. And several hours of good, deep sex standing up had taken their toll on him. Unlike Snake, his mind was foggy, his thoughts blurry and confused, and his body aching and tired. He was done and could go no further, and he told Snake so, with just the right hint of apology for failing to continue pleasing his newfound friend in his tone, something Snake greatly appreciated.
 
"I'm sorry... I can't... go on anymore..." came the nearly inaudible whisper, mumbled into Snake's back.
 
"Then I think it's time...." Snake rose a bit, his tail shifting, indicating that his friend was to move back a bit without actually moving away from him entirely.
 
"T-Time?" Koosh's voice was confused, tired. As he did what Snake wanted, getting up off of him, pulling free of the well-used asshole with a long, thick "schlllorrrrpppp," his glasses, teetering on the end of his nose, slid off. They landed against Snake's upper back and slid down his lower back, one arm coming into into contact with the base of that thick tail, then went over the reptile's left ass cheek and fell down to splash into the shallow water. "My glasses..." the squirrel cried out.
 
"Relax," Snake assured him. "You won't need them in a moment."
 
The glasses were forgotten. "I understand... but everything's so blurry..."
 
"Just follow my instructions exactly and aaaaall will be well," said that persuasively hypnotic voice as Snake moved back out to the rock he'd originally been sunning himself on when the squirrel found him.
 
It was getting late, the sun beginning to go down behind the cliffs the waterfall flowed down from. Time to end this so he could he could get back to relaxation the friendly explorer had so unwittingly interrupted, but this time deep in his cave behind the falls and not on the rock. And he wouldn't be alone. But the squirrel wasn't coming with him in the way he thought he was, grunting as he was gently jerked along behind the gracefully striding Rilvazen by that tail which controlled him probably even more than the confidence in Snake's voice.
 
"I'm going to bend over this rock," Snake said, laying one hand palm down upon it, "and you're going to shove yourself up my ass." He made sure to draw out those last few S's long and slow, and give his tongue a good flick as he glanced over his shoulder, the gaze that drilled into the squirrel's eyes making it clear he was dead serious and would listen to no arguments.
 
This command didn't faze Koosh in the slightest. In fact, it struck him in that moment as the most reasonable thing to ask for in the entire world, so fully was he under the horny and hungry Rilvazen's sway. He watched as Snake bent over the rock and the tail, releasing him, was raised up, exposing that asshole he'd been drilling for almost the entire day, leaking still fresh cum which drooled over over the heavy reptilian balls. Snake's own cock was still hard and lay alongside one thigh, drooling its own mixture of leftover jizz from his last orgasm and pre from his impending one.
 
"Make sure it's good and lubed up," said Snake. "Grab handfulsss and sssslather it onto my asshole, then shove yourssself in." He winked.
 
In a daze, the squirrel, squinting due to the world being a blur to him without his glasses, reached forwards and groped along between the spread ass cheeks, making Snake tense, his asshole quiver and pucker, oozing more cum, which the squirrel dug his fingers into. He scooped up great heaping handfuls of the stuff there was so much of it, and smeared it on the asshole... and in it, shoving his cum-covered hands into that orifice, and from there plunging both arms in to the elbow, then the shoulder, grunting as he began to follow Snake's command to feed himself to that ass.
 
In he went. He ducked his head. The asshole spread over it easily and slurped it in. With his arms forward and his shoulders thus pushed up, Koosh made a narrow figure to enter Snake from behind, and with all the cum he'd just spent pumping into his reptilian companion for several hours lining the exterior and interior of the rectum and the walls of Snake's bowels, he was sliding into the reptilian male so smoothly that Snake was barely having to do any work at all, though he did occasionally grunt and clench, and use the dangling tip of his tail pressing against first the squirrel's lower back and then, when he was swallowed up to his belly button, cock dangling still hard, against his taut buttocks.
 
The Rilvazen hissed and moaned in delight, rising up a bit so his cock would hang low off the rock, allowing him to stroke it as he felt the weight of the squirrel's bulge pushing his squirming stomach out and down to be cradled by that reptilian thickness. His tail tip teased against the explorer turned prey's pert asshole briefly, then slid over his balls and pushed his cock forward so it would be pressed against his belly when it went into him and not be bent back painfully. Snake was many things. But though he was casually snuffing this cute squirrel out of existence because he felt like he needed something up his butt a bit bigger than the other male could provide with just his cock, he didn't intend on causing him any unnecessary discomfort. Thus pressed against the belly, the cock would remain upright as it was taken in, and Snake's tail retracted as the head entered and was held firm against the squirrel's tummy by the tight, clenching anal ring. His asshole and Koosh's own eager wiggling could take it from here.
 
Speaking of wiggling, he thought, he added, loud enough to ensure he was heard by the male almost all the way inside of him, "Ssssquirm for me!"
 
Squirm Koosh did, kicking and wriggling as bit by bit he slid up into that ass. Snake continued pumping his fist along his cock as his belly kept ballooning outwards as more and more of the other male was added to it. Past a certain point, though, he realized their present position would make his renewed participation necessary, as just how slickened up his rear entrance was, how easily it was for Koosh to slide in, began working against them the moment the squirrel's feet left the bottom of the lake and rose from the water, toes wriggling. Now gravity and the slickness would threaten to make him slide back out just as easily as he'd been sliding in, unless Snake intervened.
 
Not wanting to give up what he'd decided to claim, he shifted; his tail grabbed one ankle and he rose up, hiking his ass up high, using it and the tail to lift the legs up. Now his ass was in the air and the legs and tail pointed up towards the gradually darkening shy, and now he grinned as gravity became his ally and not his enemy. He had but to relax his sphincter and let the weakly wriggling legs and long bushy tail slide in on their own, dragged down the slick anal tunnel by the prey's own weight... which is precisely what happened the moment Snake's tail released its hold on the one ankle.
 
"In you go," Snake whispered, more to himself than to his prey, because there was no way the squirrel could hear him.
 
He closed his eyes and relaxed with pure predatory delight as the now stiff and unmoving legs but wildly flicking tail went down and in with a slurp that was audible even over the roar of the waterfall. In seconds all that remained were the twitching toes and a tuft of fur from the very tip of the squirrel's big, bushy tail, and those vanished with one single, final clench of the Rilvazen's powerful anal ring. Glurp. Some cum leaked free and dribbled down between the lovely ass cheeks as the closed, sealing the rectum from view.
 
"Ahhhhh," Snake sighed happily. "Rrrrff... in you go, my squirrely butt-filling."
 
He jerked off for a few more minutes as he felt the prey - he could no longer properly be called a squirrel now, having been reduced to nothing but Snake's prey - squirming through his bowels and colon, and enjoyed the feeling of the fitful but ultimately fruitless wiggling bulges pressing outward, and came with a loud hiss and a flick of his tongue, splattering his seed all over the rock he was on.
 
"You feel so good and warm inside my cold-blooded body," he told his greatly appreciated friend. His tail flicked into the water and returned with the glasses that had slipped off his prey's face earlier. One lens was cracked. Snake transferred them from tail to hand, examined them, then put them on. They weren't a perfect fit, but he managed. The world looked all super-magnified and slightly blurry through them.
 
"Oooooh, look at me!" he said, affecting an imitation of their owner's voice, "I'm a big important explorer who wants to blaze new paths!" Chuckling and returning to his normal voice, he told the bulge, "You're not the firssst to go up there, my little--"
 
He was cut off by some fitful wiggling and for a second it seemed as if the prey might slide free. Again, that slickness working against him.
 
"Oh nooooo you don't," he chided, wagging a finger at the bulge, where impressions of the squirrel's face and hands could be seen pressing out gently, clenching his asshole extra tight to ensure everything stayed in where it belonged. "I've got you now and you're coming with me. You're mine forever. You belonged to me the minute you laid eyes on me." He chuckled and rubbed over the belly bulge. "Such a good butt-snack."
 
"Now then," he continued, getting up off the rock, feeling the weight of the squirrel settling in as his belly hung down. Keeping the glasses on, he walked towards the waterfall. "Now that you're all tucked in and settling down for a long nap, the longest you'll ever take, and one from which I'm sorry to say you won't awaken," he added, prodding the bulge with a finger, eliciting renewed struggles which delighted him immensely, "I think it's time for me to turn in as well." He walked into the shimmering wall of water and vanished behind it into the depths of his cavern lair, leaving behind his cum drying on the rock in the middle of the lake, and a shirt, shorts, shoes, socks and backpack lying discarded on the shore, forgotten now. Unimportant, really. If anyone found them, they'd assume their owner went skinny-dipping, and if they persisted in searching for him, Snake would be all too happy to show them where he went.
 
THE END.
