A Great Dane morph investigates slugs congregating in an underground cavern.

It goes as well as you'd expect.


Chapter 1.

According to the tracker display the tagged creatures were converging to one location. Hermes adjusted the device to overlay all the channels onto a single image. With their history for each creature also overlaid on the graphic it became obvious - every creature the survey team had tagged was making its slow way to a single point on the map. The tall Great Dane morph scratched his head and adjusted the display again. Extrapolating the progress of the creatures gave him a rough location - an unremarkable lumpy area of otherwise swampy ground about ten kilometres from the science module.

This world had only one non-plant form of life - a translucent, slimy, slug-like creature ranging in size from around five centimetres to over twenty-five centimetres. Over the course of the previous several years survey teams had been tagging the slugs with a harmless isotope so they were trackable from orbiting satellites. Many thousands of the creatures had been tagged before the survey teams departed.

Otherwise the planet was unremarkable. Human- (or morph-) breathable atmosphere, temperate climate, some valuable mineral deposits (but probably too few to justify an actual mining operation), 90% of the planet surface was water and the other 10% too swampy for serious colonization. It was one of thousands of worlds almost exactly like it in the Unitary database. Should Unitary Exploits ever want to do anything with the planet, it had been categorized, surveyed, tagged and bagged. It didn't even have a name, just a number.

At an imposing 220 centimetres tall, Hermes was certainly the largest animal on the planet. His genetic soup of Great Dane dog and human DNA gave him strong, well-defined musculature in his legs, arms and deep chest. It would be easy to mistake his fur-covered head and face for un-altered Great Dane dog - he had the same square muzzle and large, droopy ears. Where most of his fur was a light brown, his muzzle and ears were black like a regular Great Dane. But inside the broad skull was a brain as intelligent as any (actually more-so than most) regular humans. Great Dane DNA gave him a thin waist and broad shoulders and short, brown fur covering his entire body. Human DNA gave him intelligence, speech, an upright posture and dextrous hands.

He walked on two legs almost exclusively and used his forelimbs as hands and arms. Mostly. Unitary Exploits had done an impressive feat of genetic engineering by creating the anthropomorphic animals for specialized planetary exploration. The Navy Seals had been particularly adept at wet world exploration and cataloguing in the early days of humanity's expansion across the galaxy. The bears and wolves endured the colder worlds well. Morphs, as they were called, proved more versatile than machines at adapting to the unexpected things a new world could throw at exploration teams.

But the genetic blending had its... idiosyncrasies. Hermes' legs were mostly dog-like. Sure, he could walk upright, but he was always slightly off-balance on his pawpads. Having a tail helped him balance, but if he wasn't careful he could sweep a desk clear of laboratory equipment as he turned around in the science module. Buying trousers was always a stressful time - nothing ever fit correctly over his tail. There didn't seem to be a decent way of having a tail that didn't leave your butt-hole exposed to the world regardless of your careful tailoring. If he needed to run very fast Hemes could drop to all fours and gallop along like a leggy Great Dane dog. It was hard on his hands, but if he wore tough gloves he could outrun any human, and keep running for many kilometres.

As the only person remaining on the planet, Hermes was essentially a caretaker for the outpost. Really it was quite an easy assignment. The weather was consistently warm and humid, the environment was completely benign, and the small collection of buildings which made up the outpost mostly maintained itself. If it wasn't for the infinite variety and entertainments of the Outernet, the assignment would actually be really boring.

Everything you could imagine and so much more you could never imagine made up the vast Outernet communication network which spanned the galaxy. Every facet of human (and other) existence was instantly available to everyone everywhere. The sprawling Outernet had unquestionably become a sentient being in its own right many years ago. Fortunately it was too busy giggling over videos of 'Kzin who look like Hitler' to become evil. So long as those whacky Kzinti with brush moustaches kept uploading videos of their antics trying to fit into cardboard boxes the galaxy would be safe.

So Hermes was never bored; at 24 years old he had a job he enjoyed which had very few actual responsibilities, and he supposed he was happy. Isolation suited him. Morphs were always regarded as something of a curiosity amongst 'normal' humans. Even in this tolerant and accepting society, being different could make you self-conscious. Hermes was never very comfortable around other people - their scrutiny would make him withdraw shyly. This remote posting was perfect. Unitary Exploits, the great conglomerate of science and commerce of humanity had assured him of lifelong purpose and comfort. Maybe one day he'd even lose his virginity.

But now this. Every tagged blip on the display inexorably making for one place. Well, it was something new and Hermes supposed it was the reason Unitary was paying him the big bux. He'd have to go and investigate to see what was special about a lumpy hillock in the swamp. But, you know, no rush. The third season of 'The 75thDoctor Who' was absolutely hilarious, and then he had 'Game of Thrones: The Desert Years' to wade through. Eight (count them, Eight!) seasons to binge on. No rush.

Four days later Hemes made preparations to investigate the congregation of the slugs. Polymer fabric made for tough-but-light trousers and shirt which would protect him from the scraggly plants and keep him cool in the humid air. Tough work boots of the same polymers would protected his paws from the swamp. Not that he'd be walking - it was ten kilometres to the convergence point. He'd use a travel pad to carry him over the swamp. Another miracle of Unitary engineering, the travel pad was about the size of a small suitcase, silent, fast, antigravity travel. As he sped over the mud, water and shrubs a small remote drone camera the size of a baseball hovered nearby to record his findings. Satellites beamed the live video and scientific data directly to Unitary science planets. It was all very easy and very instantaneous. Someone may be watching him live, but most likely it was just a computer monitoring the video and data. Hermes supposed if he got into real trouble a rescue team would immediately be notified. But there was nothing malign on this world.

From above, the small hillock was difficult to discern. It was the same muddy colour as the swamp, with the same homogenous covering of small shrubs and bushes. There was no visible sign of the congregation of slugs but his scanner display assured him every individual signal had merged into one bright point beneath the ground.

Hermes descended to ground level on the pad and tested the surface. It was firm beneath his boots as he stepped from the pad. The drone camera hovered nearby while he explored the hillock. There must be some way to access beneath the surface.

Behind some matted undergrowth Hermes discovered a rough cave entrance. It wasn't especially large but if he needed to he could crawl through it, although he'd prefer not to as the walls and floor were damp earth. A few taps of his fingers on the scanner display send the drone camera down the tunnel to explore. The tunnel sloped easily down into the hillock and seemed quite straight. About twenty metres into the tunnel the drone met resistance from thin plant roots growing down through the ceiling. While they didn't look especially strong, the roots were just enough to prevent the forward progress of the hovering camera.

Returned video signal gave tantalizing glimpses of something glowing greenly just beyond the root barrier. Hermes tapped at the remote controls but he couldn't get the camera to advance further. A few more taps on the remote controls and he'd scanned the topology of the area ahead - a surprisingly large cavern approximately five metres across and four metres high. With a resigned sigh Hermes realized he'd have to explore physically by crawling down the tunnel. Scientists would probably be very curious about that green glow and what the slugs were up to down there.

Soft moist soil squeezed up between his fingers and soaked into the knees of his trousers as he edged forward. He winced - it was kind of icky and cold, and he'd never really liked being muddy. Mud was always difficult to get out of his fur. But his curiosity pushed him onward, and really he couldn't give up while the drone camera was watching. Fortunately the ground felt quite solid just a few centimetres under the damp soil so the crawling forward was easy.

Something squished under his knees and he slipped slightly down the sloping tunnel. Apparently the gradient was a bit steeper than it appeared. Hermes put his hands out to the sides of the tunnel to belay the slipping. But the walls were covered in the same slime he'd just put his knees into and didn't offer any purchase. Inexorably he slipped further picking up speed. He wasn't moving fast - the slope was gentle - but he couldn't stop his sliding toward the drone camera and root barrier. He hoped the barrier was enough to slow him.

Actually, it wasn't. By the time he'd reached the end of the tunnel where the drone hovered he was sliding forward at a good walking speed. His forehead bumped the drone forward into the roots which offered little resistance to his sliding. Mud and slime rained into his face. For the last meter or so with his eyes squeezed shut he slipped toward the cavern, hardly slowed.

Quite startlingly the ground beneath Hermes hands and knees vanished as his momentum propelled him out of the tunnel into the cavern. For a single breathless moment he was falling, flailing his arms, blinded by the mud in his face. It was only a short fall of a metre or so - enough to knock the breath out of him when he landed in the soft-ish mud at the floor of the cavern. Only his pride was wounded. He cleared the mud from his vision and looked around.

Chapter 2

Green bioluminescence lit the space around Hermes. Slimy slugs in their thousands covered the walls and ceiling of the cavern and each one glowed a slight green. Around and above Hermes the cavern was entirely covered by a thick layer of slugs. Each slug wetly reflected the light from the other slugs to create a pearlescent rippling illumination almost as bright as Hermes' office in the outpost.

The slugs were moving; writhing and undulating on the walls around Hermes. Fascination held him - the slugs twisted and entwined in a slow dance. Giant slugs would rear from the ceiling surface and appear to start falling before being suspended by a sticky tendril made up of dozens of smaller slugs twisting together making a living rope.

Two slugs each about the size of a banana wove themselves about the other, suspended by slime and cords of smaller slugs. One of the pair exuded a questing pseudopod which wavered in the air for a moment. Opalescent slime dripped from the small limb as it stroked tentatively over the blunt tip of the other slug. Peering closer, Hermes could see an indent forming in the surface of the second slug where it was being caressed by the finger-like limb of the first. The indent grew deeper and became an orifice into the depths of the second slug. Slowly and sensuously the finger circled the outer lips of the orifice, then slipped deeper. Hermes was transfixed by this. It looked almost as if....

Oh my god... they were fucking!

As the first slug's pseudopod penetrated to the depths of the second both slugs shuddered. The body of the slugs was translucent almost to the point of transparency so Hermes could clearly see the tendril penetrating deep into the orifice. A blob of whitish fluid began to accumulate in the depths of the first slug. Their green glow intensified as the writhing of the slugs continued faster. The first slug gave a shudder - a ripple which began at one end and squeezed up the body to the end where they were coupling forcing the whitish fluid along the pseudopod. The bulge of fluid travelled into the second slug whose undulations suckled the package of milky fluid deeper. Both slugs simultaneously shuddered and their luminescence brightened. Answering bright glows radiated out from the smaller slugs suspending the two mating slugs. Like a stone dropping into a pool of water, the expanding ring of bright glow flowed from slug to slug over the roof and walls of the entire cavern.

It was eerily beautiful - every slug had participated in the mating orgasm of these two. Hermes realized he could show this to other people and gain Outernet Fame Points at the same time. Mating videos always gained millions of views - everyone was a pervert but pretended they weren't. So long as the videos were labelled 'Weird and funny - horses mating!' no one felt guilty about watching them. Using his scanner pad he summoned the floating drone camera closer. A few commands put the camera into higher resolution recording and told it to focus and zoom in to points of interest. Throw in a few interspersed wider and distant shots of the cavern. While the close-ups would be nice, getting a wider overview of the cavern and the play of lights over the shiny surfaces of the slugs would make it more professional-looking. A blinking red light on the front of the camera assured him it was recording in highest quality. Video relayed to his scanner pad showed Hermes it would be well-lit with the indirect illumination from the slugs. With a couple more taps on screen he linked as a live stream to the Outernet with the title "Weird and funny live-stream. Glowing slugs mating!" Okay, it was only slugs but he was certain he'd get at least a few Fame points from the stream. Surely someone somewhere was interesting in slugs fucking.

Above his head a long tendril of smaller slugs were twisting and entwining to make a living rope while another similar tendril was growing nearby. Perhaps in this cavern they acted something like a single compound organism. Great blobs of large slugs oozed their way to the tendrils. The drone camera flitted away from Hermes and focussed on the nearest tendrils as more and more mounds of small slugs began to form into dangling ropes. At the end of each pair of ropes two larger slugs would begin their slow and weirdly erotic mating. As each pair of slugs achieved their climax a bright glow would flow out and around the cave like an expanding ripple on a pond. Video would show a close-up of the finger-like tendril of one slug penetrating the orifice of the other, the shuddering release and injection of fluid, and then the camera would pull back to show the interplay of rippling light over the walls and ceiling of the cave. It was absolutely beautiful.

With each bright glow, Hermes' sensitive nose would detect a slight scent of orange-blossom.

Living tendrils grew thickly from the walls of the cave. Soon the entire interior of the cavern was dancing with lights which rippled and expanded like water droplets sprinkling into a pool. The only sound was a faint 'shushing' as the slugs moved against each other.

A small beep from the scanner notified Hermes he had one million viewers watching his video stream of the cavern. He grinned - it was a fine viewership. Enough Fame points to give him a better rating and cooler equipment for his next online gaming session.

After about thirty minutes the light rippling over the cave walls dwindled. The drone flitted more slowly as the show drew to a close and the viewers left the stream.

Orange-blossom scent had seeped into the air. While heavy, it wasn't a cloying smell. Who knew: slug semen smelt like flowers. Hermes giggled a little at the thought. An advisory note popped up on his scanner: While not toxic, the scent may have mildly euphoric effect on certain canids.

Advisory? Okay, nothing to be concerned about. Not even a 'Caution', or 'Warning'. Or 'Waution, corning ahead'. Hermes grinned at his joke. His great Great Dane tongue lolled out the side of his jowls and he panted with glee. Wait, it wasn't that funny. Dammit. With a rubbery sound and flying drool he shook his head to clear it of the orange-blossom cobwebs in his mind. Must be time to leave this place.

Chapter 3

Someone tapped him on the shoulder.

Hmm? He turned around. Wha? There was no-one there. But on his shoulder lay one of the sticky slugs. It must have fallen from the ceiling. Ick. It was wet, slimy, pulsing very slightly and about ten centimetres long. Just, ick. The scanner assured him it was completely benign; non-toxic, non-aggressive, slow-moving. Tentatively he picked at it with his fingers. It felt surprisingly warm - Hermes had been expecting it to be cold. Weren't slimy things always cold? The slug came away from his shirt easily. No, wait, it had taken a slug-shaped fragment of his shirt with it. Apparently the tough polymer molecules of his shirt fabric were easily broken down by the slimy surface of the slug. And it stuck to his fingers like a huge, disgusting booger. As he watched, the fragment of fabric on the slug dissolved away. Hermes shuddered and shook his arm to flick the slug off his fingers. It still stuck. His fingers tingled mildly. Another advisory note popped up on his scanner: While not toxic, the surface of these creatures exudes a chemical which may cause mild euphoric effects in certain canids.

Someone tapped him on the other shoulder.

Hmm? Oh, another slug. Twice the slug for twice the boogery fun. Watch out, the booger-man will get you. He giggled again. Oh hell, his head was full of orange-blossoms and his fingers were tingling, stuck to the first slug. Carefully he put the scanner pad on the floor of the cavern and used his free hand to pick at the second slug on his shoulder. It too came away easily, sticking to his fingers and leaving a slug-shaped hole in his shirt. Now he had a slug stuck to each hand. His fingers tingled.

Perhaps he could wipe one slug off with the other. Ah, nope. The two slugs stuck fast to each other, joining Hermes' hands together.

Three people tapped him on the back.

Slugs had begun to rain from the ceiling. Slugs huge and slugs tiny, singly and in clumps fell from the ceiling and walls. Hermes was pelted with the nasty things. Wherever they touched the fabric of his shirt they'd dissolve a hole, then fall away. Several fell onto the top of his head. Eek! He squealed and instinctively went to brush them away. His hands stuck to the slugs on his head. His hands tingled. His head tingled. Everywhere a slug touched him he tingled.

Around him the floor of the cave was littered with writing clumps of glowing slugs, making it awkward to take a step. Near his feet the scanner chimed to assure him he was in no danger. Apparently the slugs avoided its alloy case. It rested on the floor clear of their slimy bodies. Oh, and also viewership of his video stream was climbing again.

Oh hell.

Fortunately the drone camera had advanced collision-avoidance. It could flit around dodging every falling obstacle. Impassively it watched with a blinking red eye as Hermes shirt finally succumbed to the rain of slugs and fell away. With his hands stuck to his head his chest was drawn up and his washboard stomach muscles became apparent. Gingerly he tried stepping between the slugs on the floor. He stretched a long step to a relatively clear area. Writhing mounds closed the gaps and surrounded his boot. His foot stuck in place, held by a web of slugs. Hermes realized with a start he couldn't lift his other foot either. The sheer weight of thousands of slugs all stuck together was more than he could lift. So he stood stuck with his legs wide apart and his hands on his head.

While the slugs could stick firmly in place, they could also excrete enough slime to allow them to crawl over each other easily. They oozed down his back over a tingling sticky trail of slime in his fur. Two trails of slugs crawled down the small of his back over his hips. As they reached the waistband of his trousers the polymer molecules broke down and dissolved ahead of them. One convoy of slugs went down each leg, neatly slicing his trousers as they went. The fabric fell back as the trails of slugs worked their way down his hips and thighs. To Hermes extreme embarrassment the falling fabric exposed his genitals and buttocks and he couldn't even move his hands down from his head to cover himself.

Beep. Helpfully his scanner display informed Hermes his video stream viewership was back over one million viewers. He blushed hotly. This was appalling. He tried to contort himself away from the camera to hide his nakedness but the drone was programmed to follow scenes of interest and follow them it would, weaving and dipping around to keep Hermes' genitals centre screen. Soon the trail of slugs reached his ankles and his trousers fell completely away, dissolving into the writhing morass beneath him.

Beep. Two million viewers. Social networking was spreading the word there was a worthy live stream - Something New on the Outernet. Humans had always been fascinated by Morph anatomy. Hermes was a fine example of a perfect blend of human and canid. He was tall, slim, well-muscled, had a broad chest and adorable Great Dane head. His fur was a golden brown except for his black ears and muzzle. And here he was, naked and splayed out for the galaxy to admire. Oh hell.

Hermes could feel his boots dissolving around his paws. The thicker, tougher polymer mouldings of his boots had resisted the slime, but now they too were falling apart as their molecular chains succumbed. Perhaps as soon as his boots were gone he could quickly free his paws. He focussed on the feelings around his back paws. Any moment now...

Unfortunately with his attention so focussed on his feet Hermes didn't notice the long chain of slugs which had grown down from the ceiling above. Hundreds of slugs were forming a long, rapidly thickening arm reaching from the ceiling of the cavern down to the top of his head. Tingly warmth enveloped his hands. With a start he realized the slugs overhead had encircled his wrists. At the same moment the last of his boots dissipated away, leaving his paws in the tingly embrace of the slugs.

Hermes grimly expected the thick arm of slugs to continue to cascade down over his head. Instead the mass of slugs near the ceiling widened. Half the slugs at the base began to crawl left, half began to crawl right so the base of the arm split in two. The split widened and travelled down the mass of slugs, becoming two separate columns. Each column extended from the ceiling down to one of Hermes' wrists. Beneath his fingers Hermes could feel the two slugs stuck to his head begin to squirm. They exuded more slime and the lubrication allowed them to crawl along his scalp. Hermes' hands were abruptly free from his head and the slugs. They still tingled from the slime but with relief he could flex his fingers and move his hands away.

Relief was very short-lived. When he tried to drop his hands he realized the thick rope of slugs from the ceiling had bound his wrists. It was far too strong to break. Using all his weight on first one arm and then the other, and even pulling against the force of the slugs binding his legs to the floor he was unable to break free. Inexorably as the two armies of slugs forming the ropes bounding his wrists crawled in opposite directions across the ceiling Hermes' arms were pulled up and apart. Now he was completely spread-eagled; legs apart and arms apart, bound in place. For a terrible moment he wondered if the slugs would simply pull him apart, limb from limb, and feast on his corpse.

But even as he fearfully wondered and struggled against his restraints the pulling on his arms slowed and then halted. He was simply being held, exposed. Beep. Beep. Helpfully his scanner pad reminded him that millions more people now had a glorious view as the drone camera pulled back to show him bound, spread in a big 'X', completely vulnerable.

Beep.

Around his feet the mound of slugs were milling and piling deeper. Another mound of tiny slugs formed between Hermes' legs and grew upward from the floor. They touched against the sensitive skin of Hermes' low-hanging balls. Being part Great Dane, his scrotum hung a good ten centimetres down between his muscular legs. The skin was hairless and shiny black and very sensitive. Hermes strained against his bonds and tried to move his hips away or pull his testicles up. But the slugs had entirely enveloped the two orbs in their black sack.

Tingling began in his balls. The slime from the slugs fully coated his scrotum. Actually it wasn't an unpleasant feeling after all. The slugs weren't pulling against his scrotum or harming him. They were just crawling over his balls and making them tingle with their slime. They crawled upwards to the base of his penis.

Beep, beepbeepbeep. The indicator on the scanner pad was rapidly counting up his viewership - now in the tens of millions. Oh hell. He felt as if he was blushing over his entire body even as he struggled against his bonds and wondered if he was going to survive.

Great Dane genes had also given Hermes a canid penis. He had a furry 'sheath' extending almost from his navel to his balls, entirely covering his penis when he wasn't aroused. His penis, like a dog's, had a baculum (or penis bone) which kept it rigid even while unaroused. So as the slugs crawled upwards they pulled his sheath back, exposing the red flesh of his penis proper. Hermes could only stare down at what the slugs were doing, hotly embarrassed they had exposed such an intimate part of his anatomy to the hovering drone camera. With a slight hum the camera flitted for a close-up of the bright red flesh of his penis exposed clear of its sheath.

One of the larger slugs - a monster over thirty centimetres long with a body thick as your arm - made its way up the column from the floor of the cave to the Dane morph's dangling balls. It oozed upward over his sheath but didn't touch his exposed penis... yet. As Hermes watched in fascinated horror, the blunt end of the slug leaned outward from the mass of slugs coating his sheath. The slug seemed to be questing around in the air near the exposed tip of Hermes' penis. An indentation started forming in the end of the slug and rapidly deepened to become an orifice into its body. Slowly, very slowly, the open end of the orifice slipped over the red tip of Hermes' penis. At the first touch of the slug against the incredibly sensitive flesh of his penis, Hermes' jerked back with a jolt, certain the touch would be cold and unpleasant, and bring pain.

But as more of the slug's orifice enveloped his penis Hermes felt warmth and a slight tingling. He could clearly see the red flesh of his penis penetrating deeper into the body of the slug. Rhythmic squeezing of peristaltic motion over his penis as the slug edged forward felt really quite pleasant. It felt as though the slug was sucking his cock deep into itself as it enveloped the entire exposed length of his penis.

From the warmth, the squeezing, and that soft, pleasant tingling on his cock, from the fuzzy cobwebs of orange-blossom scent in his head, from the tingly massage over his balls, Hermes began to get sexually aroused. Horror dissipated. He looked down and watched his cock begin to lengthen and swell inside the transparent body of the slug. Like a dog's, Hermes' penis had a bulbous swelling at the base. Normally when a dog mates a bitch this swelling (or 'knot') would lock the two of them together to ensure fertilization. But now the swelling at the base of his cock was growing inside the slug. At full arousal Hermes' Great Dane cock was over 25 centimetres long from pointed tip to base, and he had a baseball-sized knot. Almost the entire length of the giant slug was now over his cock. Sensual squeezes rippled down the length of the slug from the bulging end stretched tightly over his knot all the way to the tip of his cock.

Pleasure became overwhelming. Hermes closed his eyes and leaned his head back and simply savoured the rhythmic suckling and tingling on his cock and the tingly sensation on his balls. Unconsciously he was thrusting his hips forward slowly to meet the suckling sensation and this in turn made a slight pulling sensation from the column of slugs surrounding his balls.

Another tingling sensation began deep in Hermes' abdomen - the first twinges of his building orgasm. For the first time in his life something other than his right hand was stroking him toward sexual release. He groaned as the squeezing around his cock tightened. The slug was rippling tighter and faster. Another twinge deep in his abdomen, and his balls pulled upward as he came closer to orgasm. The tingling over his cock was better than anything he'd ever felt. Like a warm vibrating glove expertly stroking the length of his cock, so very slippery and yet squeezing tightly over his knot. He groaned deeply as he felt the tension building inside him. Gods, he was going to cum, he was going to cum.

With a sudden jerk forward of his hips, Hermes' orgasm exploded in release. Intense pleasure burst through him as his cock throbbed and bounced, shooting his semen deep into the suckling orifice of the slug. Jet after milky jet shot from the tip of his cock. With sudden intense squeezing, the slug milked his cock for all the semen he could give. Hermes' head was back and his tongue lolled out the side of his mouth as he panted through the pleasurable release. His eyes were tightly closed and yet with each burst of pleasure a flashbulb was shining through his eyelids. He dropped his head forward and opened his eyes to watch the semen squirt from his cock, growing into milky blob deep in the slug. With every jolt of Hermes' orgasm the slug would suddenly glow brightly green. And the nearby slugs would relay the bright flash. An expanding ring of bright light travelled down the column of slugs, across the floor, up the walls and ceiling to the ropes of slugs holding his wrists. Every pulse of his cock started a ripple of light in that giant pool of slugs, as though the pleasure pouring from him was pouring through every slug in the cavern.

Involuntarily he was thrusting his hips forward as though he were mating a human (or morph, or feral) lover. Hermes' cock was an angry red colour with a bright network of veins inside its transparent sheath of slug. It throbbed and jumped again as another jolt of pleasure forced more semen to pump into the slug. A bright flash of green swept the cavern - far brighter than any of the flashes from the earlier mating slugs. Orange-blossom sent flooded into the air.

Another gift from his Great Dane genes was long, drawn-out orgasms. Dogs tie together for up to twenty minutes or more, all the while the male dog is ejaculating seminal fluid into his bitch. The sperm-rich fluid happens early in the mating but for the entire remainder of the 'tie' together the male dog squirts clear fluid. Although the frequency of the surges Hermes experienced gradually tapered off, periodically the tingling and squeezing from the slugs would bring forth a sudden volley of squirts of seminal fluid and his cock would jump and pleasure would flood back into him.

Drool ran freely from his tongue. His head lolled forward and he panted with open mouth. Each time his cock erupted more jets of cum into the slug, he'd groan through the ecstacy.

After around twenty minutes pleasure centred on his cock began to dissipate. Hermes wearily raised his head and became aware of a constant beeping sound near his feet. Numbers were flicking rapidly on the display of his scanner. With a 'ding!' the one billionth viewer count rolled by.

Oh hell. One billion people across the galaxy had just witnessed the lewd display of translucent slugs suckling this shy dog-morphs cock to orgasm. Live.

Realization made his cock suddenly shrink back in embarrassment. With a wet 'splat' the giant slug slipped off his cock and fell into the writhing mass at his feet. The creature was visibly bulging near the end from a great wad of milky canine semen.

Surely now the slugs would release him - they'd drained his cock dry. He shook his head to clear it of the orange-blossom scent. But it was all through the cave. He giggled. Thoughts were wading through molasses.

Chapter 4

Behind him, unseen, another mound of slugs was forming into thick pillar. At the apex, another of the giant slugs was questing forward. Hermes felt something warm and wet stroke lightly over the ring of his anus. Startled, he clamped his tail down. Oh no. Nononono... No way. No bug was going to slugger him. I mean, the slug was going to bugger him. I mean, it WASN'T going to ... ooooh. The slug had extended another of the finger-thin pseudopods. No matter how he clamped his tail down and clenched his buttocks, the slippery finger slipped under his tail. A sensation of stroking, a warm, lubricated, tingly finger traced its way around the pucker of his anus. It caressed him lightly and sensuously. Slowly Hermes' tail lifted as he relaxed into the pleasurable stroking. He'd never tried any sort of anal play. It was heavenly. The finger traced around his pucker, coating it liberally with the tingling slime. Hermes' relaxed his clenched sphincter slightly and savoured the new sensations. Alternately the thin pseudopod of the slug would push forward with a slight pressure at the centre of his pucker, then pull back. A slight press forward, and then back again.

Drool dripped from the end of Hermes' lolling tongue; eyes closed, he was drifting in bliss. This was a delightful feeling and the heady fumes of orange blossoms enhanced the sensation. He relaxed his sphincter a slightly more as the finger pushed forward and the tip slipped past the puckered ring. Involuntarily he clenched his sphincter again at the invading sensation then relaxed as the finger slipped out. Again it pressed forward and Hermes relaxed, letting it slip into him. It was something so unusual to him but it was a wonderful sensation. Forward and back the finger slipped into and out of his anus.

The camera drone flitted closer again, zooming in to watch the invading tentacle push into the virgin arse of the Great Dane morph. Hermes was lost in the sensation - with each push forward the finger went slightly deeper and was slightly thicker. From somewhere near his feet a quite buzzing was coming from the scanner. Every now and then it would 'ding' as another billion citizens of the galaxy watched the close-ups of the thickening tentacle pushing deeper inside Hermes.

After around ten minutes of slowly stroking deeper past his sphincter, Hermes had relaxed enough that the entire thickness of the body of the slug was pushing forward. The supporting mound of slugs rocked back and forward to push the giant slug. Then with a sustained thrust forward the entire 30 centimetre length of the slug slipped deep into Hermes. With a sudden blink of concern he realized the whole slug was now wriggling inside him. But the tingling warmth of slug slime radiated outward from his lower abdomen through his entire body, washing his cares away.

The body of the slug expanded and contracted, lengthening and shortening inside him. Each time it swelled it pressed against Hermes' prostate, massaging him pleasurably from the inside.

Something warm and suckling slipped over the tip of Hermes' cock. Another of the giant slugs had been making its way up from the floor unnoticed. Hermes half-opened his eyes to watch the orifice of the giant slug slip along his cock right down to the base where smaller slugs had retracted his sheath. His cock began to swell inside the transparent sleeve of the slug's body. Every time the slug in his rectum stroked his prostate Hermes' cock would jump and swell some more. And every time his cock swelled the slug stretched around his knot would suckled harder. Warm tingles ran up and down the length of his cock, synchronized to the deep massage of his prostate.

Inside Hermes, the huge slug had been accumulating a pocket of milky fluid. Normally only a small length of pseudopod was stimulated inside the orifice of another slug. But now the whole body of the slug was rubbing and convulsing in the warm contracting tunnel inside Hermes. It was building up a massive charge of its own semen to release.

Hermes' breathing became panting. He groaned at the feeling of another orgasm building. Drifting pleasure had become an urgent need for release. Jolts of pleasure started rapidly firing in his abdomen. Unconsciously he was thrusting his hips hard to meet the suckling pleasure on his cock. Deep inside him he could feel the contractions of the slug becoming frenzied, synchronized to the thirsty suckling on his cock. Bright purple veins webbed across the surface of his cock, clearly visible through the transparent slug. He gasped and struggled - so close to cumming for a second time. Taut muscles on his legs and arms strained against his bonds to hump his hips forward and back as though he were fucking a human partner.

Approaching orgasm caused his testicles to pull upward. Although the column of slugs cradling his balls rocked back and forth in time with his thrusting hips, there was a sustained tugging sensation on his scrotum.

It was too much stimulation to endure. A mighty jolt of pleasure erupted from Hermes' groin. He jerked his hips forward to propel the semen deeper into the slug. The first jet of milky cum caused the slug to suddenly shine forth in an intense green light. Nearby slugs answered the light and the glow rippled out over the walls. A gasp turned into a groan that grew into roar as Hermes threw back his head as the pleasure drove into him like the waves of light washing over the cavern. Every intense jolt of pleasure splashed another ripple into the pool of slugs.

And deep inside Hermes as he'd thrust and clenched and squeezed in the pleasure of his orgasm, the slug too built up to its release. With a mighty convulsion the slug spat forth its accumulated wad of semen into Hermes' bowels.

Hermes felt the moment. His eyes flew open wide. Inside him he'd felt the sudden contraction of the slug. Its sudden girth was like a baseball stretching his insides almost to the point of pain. It pressed hard against his prostate making Hermes cock bounce and shoot a volley of cum. And then it suddenly released its fluids inside him. The cavern lit up in a flash of phosphorescent green.

Tingling in his abdomen became a humming, became a buzzing, became a vibrating, became a white-hot ball of expanding ecstacy. Hermes clenched his teeth as pleasure built into a sustained crescendo throughout his entire body. Orgasm was nothing compared to this. Where orgasm was a few waves of pleasure quickly tapering away, this was a roar, a conflagration of sustained bliss. Hermes' cock erupted with cum. From reserves he never knew he had he squeezed forth more sperm-rich fluids and shot them from his cock into the greedy slug. These weren't jolts of pleasure, this was a continuous wash. The surrounding cavern was a pulsing heart of green suffused with rich orange-blossom scent. He clenched his eyes closed and dropped his head, drooling freely from his panting mouth.

Floodwaters of pleasure finally began to recede from his mind. The bright, chemically-induced euphoria from the slug semen tapered off. A few desultory spasms made his cock throb and squeeze forth a thin dribble of semen.

Hermes slumped against his restraints, spent. He drew a shuddering breath and opened his eyes. A blinking red light on the hovering drone camera started back at him implacably. He groaned at it - why wouldn't it just fuck off. It blinked at him.

Surely, surely the slugs were done with him. He'd barely noticed as the transparent sleeve had slipped wetly from his shrinking cock. He had no strength to clench against the slithering length of slug that slipped freely from his anus. This must be it. He had nothing left to give them. The cavern dulled to a muted glow.

Chapter 5

For a while nothing happened. Hermes was tired but suffused with a feeling of well-being. Perhaps it was just the heady scents in the cavern soothing his mind, because he was still being held spread-eagle, naked and vulnerable.

Warm tingling flowed over his arms. Hermes looked up and saw hundreds of small and middling slugs oozing down from the ceiling. Similarly when he looked down he saw an army of slugs climbing his legs. What was happening now?

The tingling warmth flowed over his shoulders, across his chest, down his back. It flowed up his thighs to his hips, covered his buttocks and abdomen. His entire body was encased in a layer of small and middling slugs. Some had latched onto his nipples and were suckling. Only his sheath and head was free of the slithering masses. At first Hermes was vaguely repulsed. Feelings of disgust wormed past the glow of well-being. His fur would be matted with slime and slugs were crawling over every part of him. But the tingling warmth wrapped him in a soft humming blanket. The slow movement of the slugs felt like a caress against every part of him. He was soothed again and felt content.

Tingling spread up his neck and under his chin. Small slugs slithered into his jowls. Oh hell, they were in his mouth! Hermes clenched his jaws. Unfortunately, being canid and having a dog's muzzle, he was completely unable to tighten his lips. Slugs invaded his mouth, oozing over his teeth and gums, all over the inside of his jowls. He shuddered in disgust as tiny slugs slipped between his clenched teeth and slithered their slime against his tongue.

He didn't want to taste it, he didn't want to taste it, he didn't want to taste... Mandarins? Mandarins picked on a spring morning, with a cold dew on their peel. That spring day, it was early and just getting a hint of warm breeze, and the tree was laden with fruit. Ripe, easy to peel, each segment bursting with flavour in his mouth. Back then, when he was only nine years old, for a school outing to a fruit farm.

Blinking in wonder at the lucid memory spawned from the taste in his mouth, he relaxed his jaw somewhat. Maybe being wrapped in a fuzzy blanket and remembering mandarins wasn't so bad. In fact it was downright soothing. His tongue was tingling strongly and he was salivating. He swallowed down some of the slime. Actually this is quite good.

More small slugs at his groin slithered up his sheath to the opening in the end. They quested around the top before pushing their way inside. Hermes felt each one like the brush of a finger around the sensitive rim of his sheath. He felt them slip into the small opening, pushing their way down between his penis and the enclosing skin. They wriggled right to the deepest part of the sheath to the root of his penis where his knot would form. More small slugs followed. Countless small slugs had slipped into his sheath to make it bulge. The wriggled around his cock, their shape clearly outlined in the larger bulge in his sheath. The entirety of the inside of this sheath and still-shrunken cock was coated thickly in their slime.

It tickled. No, it tingled. His sheath inside and out spread tingling warmth.

With the taste of mandarins in his mouth a feeling grew in his testicles - like a dull ache of being compelled to increase sperm production. The glove of slugs covering his scrotum were undulating and contracting, massaging his balls. But surely he was spent - there was no way he could even get a hardon, let alone orgasm again.

That taste, though... the mandarin suffusing his mouth. He swallowed his saliva again. It was more than just quite good. Actually it reminded him of how he'd once smelled a feral Great Dane bitch in season. No, wait, that wasn't true. He'd never smelled a feral bitch. He'd never seen her puffed-out vulva, from her being in standing-season. She hadn't turned away from him, flicking her tail to the side to give an unimpeded view of that fertile entrance. The way she'd looked back at him, waiting and expectant, inviting him to mount up and thrust the pointed tip of his cock forward.

What? That had never happened! In reality he'd never even been near any feral dogs. Where were these thoughts and images coming from? Hermes swallowed the citrus taste in his mouth and shook his head to clear the encroaching cobwebs on his thoughts.

The ache in his balls was getting stronger. They had been chemically induced to ramp up full-scale production of semen to fill his depleted epididymis. Each testicle felt swollen and heavy.

They'd slapped against the thighs of the Great Dane bitch as he'd mounted her. Pheromones from her ovulation clouded rational through from his mind the moment he'd licked his tongue over her drippling vulva. He'd reared up and grabbed her hips. He'd clamped his jaws onto the back of her neck to pull her back so could impale her more deeply with the bone of his cock. Bitches were for fucking and this bitch had been begging for his cock. She would become pregnant from his potent sperm and be filled with a squirming brood of his puppies.

Visions of thrusting his cock into an imaginary bitch swirled in Hermes' head. He had to fuck. He had to cum. He had to impregnate his bitch and father a brood of pups.

The drone camera flitted behind the straining form of Hermes. It hovered close to his buttocks to intently watch several giant slugs approach. The lead slug rubbed the blunt end of its body around Hermes' anus. To Hermes it felt like a skilled tongue was licking him. Someone was skilfully licking around his pucker to lube him up, then pushing their tongue forward to open him out and relax him. The tongue pushed deep past his sphincter into his bowels, flexing and lubricating. Impossibly, it felt like the tongue pushed so deep into him that his sphincter had closed around it with it still inside him. And then another tongue was outside him, licking around his anus. It too pushed past his sphincter and slipped easily into his depths. The camera watched unblinking as six or seven of the large slugs squeezed their way inside Hermes. His stomach visibly bulged and he groaned at the full feeling.

Another of the giant slugs made its way up the sheath of the canid. The pink tip of Hermes' cock peaked from the sheath still visibly bulging with the wriggling creatures packed inside. A thin tendril formed at the end of large slug and quested around the cock tip. Hermes was too lost in visions of fucking dogs to feel the thin probe slip into his urethra. Well-slicked with slime, the probe pushed along the tube. Visions of thrusting bitches dissipated as Hermes felt pressure in his bladder of suddenly needed to pee. The pressure increased sharply as the probe pushed through the sphincter seal of his bladder. Hermes looked down and watched uncredulous as the slug sucked the urine directly from him through the transparent straw into its own body. It was an odd, but not unpleasant sensation. His bladder emptied completely and the slug became a bloated sack of yellow.

It reminded him of the time he'd knelt beneath a mighty stallion with its cock in his mouth. He vividly recalled the soft leathery feel of its rigid shaft against his hands as he stroked up and down its length. Suddenly the stallion had unleashed a torrent of piss, straight into his throat. He'd swallowed and tasted mandarins, not piss. The horse had thrust once, twice, three times and the giant tip flared in his mouth. He must have swallowed a litre of mandarin-flavoured horse cum. It had dribbled down his chin and over his chest, onto his cock.

He looked down again through the clouds of his vision. The yellow dissipated and vanished in the body of the slug, replaced with a suffusion of milk. He gasped at a thickening of the tendril in his urethra. It had grown to the thickness of a pencil and stretched the tube of his urethra to its limit. His cock tingled from the inside. He felt the tendril pull back a couple of centimetres before being pushed forward again. The slug was fucking his urethra.

All that horse cum had made him feel heavy and bloated, like a dozen giant slugs wriggling in his bowels. He could feel them all, writhing and contracting, rubbing his prostate and rubbing each other. In each of them a sack of white accumulated. More slugs had gathered in a clump between his buttocks. Each one grew a long tendril which poked into his anus. There must have been hundreds.

Around his mouth, thin tendrils extruded from the slugs. They pressed and rubbed sensuously against his tongue. Each slug was growing a sack of milky fluid.

A blinking light flitted across his vision as the drone camera decided it was time for the galaxy to observe how Hermes' cock grew hard again. Slugs around the base of the sheath had pulled it back to expose the entire red length of canine cock. The sheath was packed with whitening bodies - there wouldn't have been room for both his growing knot and the orgy of small slugs. The camera watched the canine cock thicken and lengthen. Hermes knot bulged to the size of a softball and became a hot red colour.

As it had when he'd mounted the stallion. He swallowed the taste of mandarin and remembered grabbing the back of the stallion's neck in his teeth. The rigid bone in his cock had made it easy to push past the clenched sphincter and fuck the stallion. He'd felt his cock enveloped in the warm body of the stallion. Like a jackhammer his hips thrust rapidly forward, slamming his swaying balls into the balls of the stallion. Canine cock pushed deep into the bowels of the stallion. The swollen knot grew even larger. Bigger than a baseball. Hermes had locked his cock into the stallions arse with a massive knot the size of a cantaloupe. His cock was longer than a baseball bat. His aching and swollen balls had each been larger than a softball, dwarfing the mere stallions' scrotum. Down in his belly he'd felt the first twinges of orgasm building - he was going to cum into this stallion and make him bear a litter of fine puppies. He'd been panting and gasping, drooling down the neck of the stallion.

The camera watched Hermes' cock throb larger. It watched with particular intensity the way canine's urethra was stretched around a thrusting probe. The microphone could clearly hear the breath whining and gasping from the dog. It pulled back for a wider view of the splayed body covered in the whitening, suckling slugs. Around the dog's mouth were dozens of smaller slugs all thrusting thin tendrils against his tongue. Gathered around the rear of the dog were many dozens more slugs writhing and probing tentacles into his butt.

Hermes suddenly thrust his hips hard forward. The tension building inside him was unbearable. The weight in his tingling body seemed to be focussing his mind on one thought. He had to cum. He needed to cum.

Oh.

My.

God...

There is a moment. As the conductor stands before the orchestra. The crowd falls silent and the musicians draw breath. Before a tsunami floods in, the waveless seas draw back. With the approach of a storm, for a moment the wind drops, the birds are silent. The anticipation holds. For a moment.

Hermes' eyes flew open and he drew in a great breath. His aching balls were pulling up against his body and every muscle in his body tensed. For a moment he stopped thrusting and felt electric jolts radiate out from his solar plexus. For a moment every slug in, on and around his body contracted simultaneously. For a moment, a small moment, everything was still.

The camera watched.

White slug fluid spurted down the tube into Hermes urethra filling it from bladder to tip with potent semen. At the same moment the slugs congregated around his anus pulsed and squirted their load into Hermes butt. Deeper in, all the large slugs convulsed and spewed their great gobs of semen into his bowels. His mouth was flooded with semen from all the bodies clustered in his jowls. Involuntarily he swallowed as he felt the pressure of his own orgasm about to burst forth.

Fire ignited. In his stomach, seminal fluid from the slugs radiated a white hot glow of orgasm. Deep in Hermes' bowels the flood of semen burned pure bliss into his body. Along the length of his cock from the inside and out he felt every nerve twang with sexual energy.

His hips thrust forward hard as the first wave of pleasure suffused him. Semen erupted from his cock in a long stream. His aching balls pulled up hard and delivered everything they could. The slug at the tip of his cock was sucking the stream of semen into its own body again. Hermes drew another long shuddering breath and groaned as incandescent ecstasy flooded through his entire body. He convulsed against his bonds as every muscle in his body contracted. He was cumming so hard his teeth throbbed and his ears rang. More fluid pumped from his cock as orgasm consumed him. He couldn't see, he couldn't hear, his entire being was focussed on forcing cum from his cock.

He had become light. He had become fire. Jolts of sexual energy arced across his twitching body. Another burst of intense white pleasure washed through him, starting from his cock and expanding up through his abdomen.

He was squeezing his soul out through his penis.

Like a flashbulb, every slug in the cavern simultaneously glowed their brightest neon green. Instead of an expanding ripple of light it was a single great explosion of brightness. For a moment it was too bright to see anything. The air became cloying with orange-blossom. Hermes' shuddered and came, and jerked and came. He was lost in the wash of orgasm. For eternity his cock jumped and squeezed out cum.

Eventually the bright glow dimmed.

Hermes had his eyes squeezed closed and shocks of pleasure were still making his cock twitch and spurt. He didn't notice the giant slug retract the tube from his urethra - it felt to Hermes like a sharp twang of orgasm had squirted a great thick gob of cum from his cock. The giant slug fell to the floor. Other slugs began to lose their grip on the ceiling.

He barely felt the many finger-like probes pull from his stretched anus. Their owners slumped to the ground. Tiny bodies around his mouth dripped down his chin, retracting their probes as they fell. At the base of his cock, dozens of tiny slugs squeezed from his deflating sheath. Around him sheets of slugs slewed from the walls to puddle on the floor.

Slugs peeled away from Hermes' body. He slumped forward and fell to his knees. Still spasming from the intense orgasm, he fell forward on all fours with his head bowed. His cock throbbed and squirted dog semen over the slugs beneath him. He barely felt one after the other of the large slugs slip from his well-stretched and lubricated anus. Each one rubbed over his prostate, setting off another volley of cum and another bright bust of pleasure.

With his head down, drool running freely from his panting tongue, Hermes was exhausted. He groaned as his cock jumped, but despite the muscles clenching only a thin dribble of cum squeezed out.

The glow from the slugs had faded almost entirely. A faint green twilight suffused the cave. Hermes' knot deflated and his cock retreated into the safety of his sheath. For a good half hour Hermes could do nothing but stay on all fours with his head down, breathing and trying to recover his strength.

Achingly slowly, Hermes raised his head and looked around. Nearby lay the scanner pad. With a desultory 'bloop' it notified him viewership had dropped away to a mere one billion. Wait, what? The graph showed viewership peaked early on in his ordeal at around two hundred billion viewers. And it had stayed there. Two hundred billion people across the entire populated expanse of the galaxy had watched him abase himself and orgasm multiple times with the slugs.

Oh hell.

An Outernet Fame badge notification proudly informed he was The Best Thing Ever. The top of the display flashed a warning message: "Warning: Seminal fluid from these creatures is a highly euphoric aphrodisiac, which may be hallucinogenic to canid species. Do not ingest!" Oh, now a warning? Thanks. He tapped on the display to summon the drone camera. Hermes pulled it from the air and mashed its staring eye into the floor of the cavern.

A few more commands summoned the travel pad to float down the earthen tunnel to the cavern. Wincing with the pain in his muscles, Hermes pulled himself up and wearily draped his body over the travel pad. It raised him up and carried him through the tunnel out into the natural light and fresh air.

Fin.
