Brothers in Arms

Twelve beers, ten shots of tequila and Dogs know how many fancy cocktails turned Kyle into a staggering, drunken mess. The high-school graduation party raved and thundered, swinging around his vision in graceful arcs. Young humans and Anthromorphs of every species danced, drank made out in every room of the house. At 3:00am the nauseous youth declared he should go home. His concerned class-mates tried to call a taxi. But the intimidating Rottweiler-hybrid angrily waved them off declaring his car could practically drive itself home. To an extent that was true; his car was the newest Sinos self-driving tech that only occasionally required his intervention.

Two of the guests implored Kyle's twin brother Trent to intervene. Almost as drunk as his brother, Trent shrugged them off. Seven foot tall angry-drunk canine Anthros weren't easy to cajole. “He c'n fuck'n crash f'rall I care."

As children the two brothers had been inseparable buddies. No-one could tell the twins apart – they had identical black and mahogany coats. Their faces were undistinguishable with bronze muzzles and dots over their eyebrows that every aunt and uncle declared were just the cutest! They were a pair of black-and-bronze dervishes hurtling around the neighbourhood on their iCycles. They dressed the same, invented games together and brought good trouble wherever the twins played. When college started the two muscular canines were naturally drawn to sports. Trent became a defensive linebacker with the football team while hockey appealed more to Kyle. Their solid build and impressive size naturally encouraged both to good defensive positions.

Their individual choice of sports fractured their brotherly bonds. Trent declared hockey was for sissies while Kyle rebutted that football was for imbeciles with no tactical skills. So they grew apart as they matured. They had different (if overlapping) groups of friends, took different classes, socialized in different places. Home visits were polite, but cold and indifferent.

Neither of the brothers had shown particular interest in dating. The girls at schools seemed a bit vapid, not really appreciating sports. While parties were fun and friends were plenty, relationships never seemed important.

Several worried onlookers watched the highly inebriated Anthromorph fail three attempts to climb into his car. Kyle eventually manoeuvred his heavy frame behind the driver's wheel. After fumbling with controls for a few minutes he lowered the window and waved reassuringly to his friends. A few moments later his car lurched in a haphazard manner from the driveway.

A secluded stretch of forested road formed part of the route from the rural party house to Kyle's suburban rental flat. Automated lane-keeping features of the car warred with the Rottweiler's erratic steering. Suddenly Kyle stomped on the brakes and hauled the wheel to skid the car to a halt on a gravel turn-out. “Dogs, I'm gonna puke!" He shouldered the door open, lurched into the treeline and dropped to his knees. With wet choking sounds the earlier sweet cocktail splashed between Kyle's forepaws. For moments the youth struggled to prevent the next cocktail joining its mate in the dirt. “Fuck, now I gotta piss," he declared to the darkness. He crawled from the bright mess while the world spun in lazy circles. A tree gave support and he managed to haul himself upright. Stabilized with one hand on the tree's trunk he fumbled at his trousers. Not even certain he'd managed to free his penis he sighed as he started peeing. Fortunately most of the stream impacted the trunk of the tree with only a little splashing back against his legs and boots. With his head pressed against the bark of the tree and his eyes closed it seemed he pissed for hours.

In the darkness a creature woke.

Newly born from a genetic accident in the labs that had created Anthromorphs the mass of flesh was discarded as a mistake. Disposal teams inadequately terminated the experiment with harsh radiations and cleared the remains for shipment to a waste-management facility. Impatient scientists harried the cleaning crew to depart so the next Wonder of Life could be created in torpid slurry-filled gestation tanks. No-one noticed or cared when the disposal team dumped the waste in a forest to save a few dollars on secure storage. Quarterly targets were met, shareholders celebrated.

Barely a week old and the apple-sized creature was dying. Cold air desiccated its flesh and its movements had become sluggish. The harsh radiations broke cellular bonds leaving the creature amorphous. But a new form lurched nearby. The body radiated warmth and its form was draped with sheets of polymers. Nutritious ammonias and nitrates puddled warmly around the base of the form. The mass extended a pseudopod toward the life-saving nutrients. At the first touch into the puddle of urine the limb expanded, sucking in the warm fluid. The bulk of the creature flowed through its extended arm until the mass was entirely in the puddle. A stream of fresh urine cascaded over creature's surface but was absorbed before the nutrients were wasted in the dirt.

Warmth and sustenance animated the creature. Nearby in the puddle were two objects built from a mix of organic material and polymers. The long molecules of the nylon fibres were perfect for augmenting the creature's mass. Just above the two objects great sheets of polymers hung like a banquet.

After an eternity emptying his bladder against the tree Kyle raised his head and opened his eyes. With one arm still braced against the tree to steady the gyrations of the world he fumbled to zip his trousers, “Whuh? Where my pants go?" His lower half was completely bare to the cool night breeze. The drunken youth tried looking around his feet in case his pants had just slipped lower. Bending over in the dark made the world lurch and twist and for a moment the restless second cocktail burbled for freedom. “Fucken whatever. Don' need pants. Oh fucksake what'm I stood in?" Kyke's rear digitigrade paws were inch deep in slime. His Nookie boots were a useless pile of unstitched leather panels suspended in the muck.

As he tried to step out of the slime his drunken world spun. The swampy mess suctioned his foot, making him overbalance. Kyle fell backward. Leaves and dirt cushioned his furry buttocks as he sat down hard. “Motherfuck! Fucken' stupid forest." He turned over to crawl back toward the blinking sanctuary of his car.

Cold still threatened the new creature. While the sheets of polymers had momentarily sated its hunger a warm refuge was necessary to allow the creature to properly metabolize its feast. Heat-sensing pseudocells detected a large warm body retreating. Faster than the human could crawl a thin tendril of flesh snaked out and quested over the departing buttocks. While the pelt of the Anthromorph insulated his body, the naked pucker of his butt-hole was like a shining beacon of warmth. There, beneath the tail glowed an inviting orifice.

So drunk was the youth that he barely felt when the slimy tendril breached his pucker. All Kyle's concentration was on crawling the few yards to his car without getting lost or losing the contents of his stomach again. The way his guts were churning and heaving, temporarily losing his ability to clench his pucker was lost in the maelstrom of nausea.

It took barely two seconds for the bulk of the creature to flow through its tendril, through the puckered defence, into the warmth. With a lurch the crawling body paused to expel the second cocktail into the dirt, creating more space for the creature to squirm deeper.

Kyle wiped his mouth unceremoniously on his shirt and managed at last to crawl into the car. Leather pressed cold against his bared buttocks. He slammed the door, secured against the dark forest.

“Proceed to the route…" advised his driver assistance. Somehow the inebriated young man steered the car onto the tarmac heading toward home. Fortunately there was no other traffic at the early hour – several times the car swerved threatening to cross the centreline as the driver's attention wavered. When the sensors noted Kyle's dozing head nodding, alarms pinged until with a sudden lurch the driver restored the car to its proper trajectory.

“Da-fuck 's my shirt?" Kyle didn't even remember parking the car but he was certain this was his driveway. When he opened the car door and clambered out he realized his torso was also bare to the night. Somewhere along the perilous journey home his shirt had vanished. Naked, the young Rottweiler lurched and staggered to the house entrance. Facial recognition unlocked the smart doorlock, allowing Kyle to slam open the door. He crashed down the hallway and collapsed onto a couch, instantly falling unconscious.

“Kyle! What the fuck!" his brother's shout roused the bleary Rottweiler where the midday sunlight had failed. “Why the fuck are you here? Where's my couch? Why are you lying naked on my floor?"

“Whuh?" it took several moments for the hungover youth to realize he was staring at his brother's shoes. “What're you doing here, Trent?"

“This is my house, you idiot. Dogs, how did you even drive here – you were almost paralytic last night. And where the fuck is my couch!" Trent's loud shouts reverberated in Kyle's aching skull.

Kyle realized his face was pressed against carpet. Cautiously, so as not to jar loose his throbbing brain, the young canine raised himself to all fours. He paused to let the waves of nausea ebb before staggering to his feet. Looking around he realized the unfamiliar décor and furnishings were not his apartment. Shamefacedly he covered his groin with his paws, “Uhh… do you have a spare robe? I lost my clothes somewhere?"

“Dogs, you're a disgrace." Trent turned away in disgust, “Stay there. I'll get a spare robe from the patio. And don't you fucking dare throw up on my carpet!" The angry football player stomped out the rear door.

Kyle looked around drowsy and bewildered. He hadn't been to his brother's apartment in more than two years. His own house was three streets away. Man, I must have been ratshit drunk!

An angry shout boomed from the rear of the apartment, “What the FUCK have you done to my hot-tub? Kyle! Get your pansy arse out here!"

Still naked, Kyle ventured out to the patio where his brother was gesturing angrily at the pool. Warning lights flashed on the hot-tub's control panel as the pumps made a despairing whine. Revealed from beneath the retracted insulating cover the water of the tub was translucent pink.

During the night the creature had slithered free of the bowels of its unconscious host. It took a few moments for its bulk to emerge through the tight sphincter of the sleeping youth. The feast of polymers in the trousers and shirt had increased the mass of creature to four pounds. Body heat allowed it to metabolize nylons and incorporate the long molecules into itself. It was hungry for more. Freed from the confines of the Anthromorph, the creature found itself perched on a veritable banquet! Spun vinyl padding cushioned fake leather coverings held framed by plastic tubing. The entire couch was a feast of polymers! Organic filaments oozed from the body of the mass and permeated the couch. Slowly, as the molecular bonds were broken down and absorbed, the couch slumped into a large puddle. Its canine occupant gently settled onto the carpet as the engorged creature slithered away. To metabolize such a magnificent repast the creature needed a warm lair with plenty of water. Outside on the patio shone a haven of warmth – bright and inviting to the creature's sensors. Its pseudopods infiltrated beneath the large hot-tub's cover and the giant mass vanished into the dark, wet haven. As much as the creature knew satisfaction it slumbered happy and content.

Bright light and loud shouting roused the creature from its rest. Immediately it recognized the approaching form of its prior host. Another very similar body was standing nearby clad in an enticing breakfast of polymer drapes. Faster than a snake could strike, the creature whipped several tendrils around and across the draped form. Where it touched, fabric parted and fell away. In less than a second the tendrils had withdrawn all the shredded material into the hot-tub where it dissolved into the pink slurry.

“Holy Bitch-mother!" Trent practically screamed, stripped naked next to his brother. In fright he leaped back, stumbling into a low bench. Lashing his arms out to belay his fall he struck his brother and the two collapsed in a tangle of limbs and deck furniture.

Alarmed, the new creature sensed distress and panic in the two bodies. In the confusion it could no longer discern which had been the kind host and which was the angry stranger. A veritable forest of tendrils whipped out of the tub ensnaring the two panicking youths. High pitched and guttural sounds made by the bodies irritated the creature. It jabbed a tentacle into the mouth of each to stifle the shouting and wrapped a few tendrils around each muzzle. In the sudden quiet the creature relaxed. With tentacles as thick as arms it lifted and rotated the two canines. It could take a leisurely few moments to examine its catch to understand how these creatures were different from itself. Their biology wasn't so far removed from its own - perhaps it could ease their distress. Analysis of the residue of chemicals found on the bodies made the creature certain it could synthesize a soothing compound.

Thick ropes bound the naked twins, their cries stymied by the fleshy tendrils in their mouths. They stared with wild eyes as they were lifted bodily over the writhing mass of translucent pink in the hot-tub. Sticky-sweet liquid flowed into their throats from the pink tubes. For a moment their panicked eyes sought their sibling before the brothers relaxed. Like the best hit of euphoric drugs, happiness and sunshine radiated from their stomachs. They still knew they were in danger but it seemed less important now. The tentacles lifted their naked bodies and stretched out their arms and legs. The brother's faced each other, limbs held in an 'X' shape, naked and vulnerable.

The examination of the canines began with the warm orifice where the new creature first gained sanctuary from the hostile forest.

Kyle should have been terrified. He was naked, suspended in the air and bound in tentacles. His identical twin was similarly held with limbs spread and a tube in his muzzle. But something sweet and fragrant poured into his mouth from the tube. Warm comfort suffused his body, reassuring him. His hangover was dispelled by the narcotics. Looking at his brother was like looking in a mirror. Both canine hybrids were powerfully built from their sporting activities. Their pelts were polished obsidian, glossy black aside from rich mahogany along their muzzles, fore-arms, and legs. Bronze highlighted their eyebrows and drew a heart-shaped patch under their stubby tails. And both were helpless, suspended above the hot-tub by writhing pink ropes. Straining against the cords was fruitless.

Kyle watched a thick tentacle slither from the hot-tub behind his twin. The tentacle was translucent pink, rippled like water and extended upward between his brother's legs. It traced around the heart-shaped bronze patch of his brother's rump. At the same moment Kyle felt something caressing his own rump. Strings of clear slime dribbled from the shaft. The circling tip traced smaller circles until Kyle felt it caressing under his stubby tail. It felt like a lubricated finger was stroking over his sphincter. Despite his clenched resistance the fingertip pressed until it breached his virgin pucker. He drew a sharp breath through his nose as the finger wriggled deeper, expanding as it violated him. It was a peculiar sensation feeling the alive, prehensile limb worming deeper into his bowels. Undulations of flesh pressed against something inside him that sent pleasurable jolts into Kyle's groin. The tentacle flowing into him was as warm as hot-tub water.

Across from Kyle, Trent knew he should be angry. Some monster was violating his virgin butt-hole. Slick flesh thickened and writhed in his rectum. But he swallowed another draught of nectar from the tube in his muzzle and realized his biggest concern was whether he'd hurt his brother as they tangled in the patio furniture. His twin was an idiot, but he was still his brother. Trent watched bemused as a second tentacle rose up from the mass, questing between his brother's legs.

These canines were certainly intriguing to the monster in the tub. A yard of thick shaft threaded the colons of the twins. The creature mused how much it had grown since the previous evening when its entire mass was contained by less than half the depth it penetrated now. It pushed in further, twining around the convolutions of the intestines. It discovered as nodules on the tentacle rubbed over the canines' prostate a burst of interesting compounds suffused their bodies. Chemical receptors along the surface pseudocells monitored the brothers through their skin, mucosa, and saliva. What other bits of the brothers could the monster examine to bring forth more of those interesting flavours?

A light touch caressed Kyle's dangling scrotum. He jolted from focussing on the wriggling sensation in his guts. Restrained by vines the canine was unable to lower his head to see his own genitals. But he could observe his brother and feel the sensations mirrored in his own groin. A stalk had raised from the mass and stroked over the black velvet sack of his twin. Coiling around the sack the tendril pulled downward until canine balls were shining taut orbs in their satin bag. Kyle struggled futilely against his bonds. While the caressing tendril had felt good, the tugging on his own scrotum was intense; not quite pain but not exactly pleasure. In his bowels nodules rubbed against this prostate, augmenting the intense stretching of Kyle's scrotum. His brother similarly strained against his bonds.

Another thick limb grew behind the twins. It coiled up and around their hips, slithering over their abdomen muscles. The blunt end of the tentacle pressed against the canines' sheath opening. Trent watched fascinated as the appendage peeled back the black sheath on his brother. At his own groin he could feel his penis emerging from his sheath while he watched his brother's rod enveloped by a tentacle. Kyle's shaft looked darker pink inside the almost transparent pink flesh of the maw as Trent watched it push deeper. Both twins gasped, swallowing down more nectar as a suckling motion began along their exposed shafts.

Bursts of fascinating chemicals were suffusing the captured males. Intrigued, the monster wanted to coax more of the delicate flavours from the struggling bodies. It had discovered an appendage not dissimilar to its own pink tendrils hiding in a black tube of flesh near the middle of the bodies. This appendage responded most pleasingly to undulating suction. As it made suctioning motions on the pink rod the shaft thickened and began forming a larger bulge near the base. The monster considered how very similar this was to how its pseudopods worked. In unconscious sympathy it grew a similar bulge inside the warm confines of the victims' rectum. By synchronizing rhythmic expansion of the bulge inside the males with the suckling motion around their shaft bright jolts of pleasing compounds radiated from their flesh.

Bright jolts of pleasure sparked in Kyle's groin. Inside him a throbbing bulge pressed against his prostate gland. At the same time a grasping mouth squeezed and undulated around his exposed penis. His knot grew as his shaft lengthened and thickened inside the maw of the tentacle. Across the tub he watched his brother's knot and shaft grow inside the translucent limb. Dark veins webbed the surface of his twin's cock. He could clearly see squirts of presemen fluid coalescing inside the suckling maw near the tip of his brother's penis. At the same time he shuddered as his own penis spurted presemen. Undeniable pleasure was stimulating him toward orgasm. And equally arousing was watching his brother stimulated in the same way. Kyle's brain flipped by the illusion of seeing a mirror of himself reacting exactly the same way. When his penis squirted a volley of presemen he watched his reflection pour liquid into the suckling maw.

At once the pressure overwhelmed the twins. Pulsing bulges in their colons sent jolts from their prostates which the suckling orifice over their knots amplified. Jolts became bursts became eruptions as the mirror images bucked in their restraints. As their taut scrotums pulled upward in preparation for expelling their load thin tendrils withdrew. Gasping through their nose, each twin fixated on watching their mirror squirt white ropes of semen into transparent orifices. Their pulses were exactly synchronized so each thought they were watching their own cock spurting as they came. Expertly, as though the monster knew exactly what they were feeling, the maw squeezed around their knots, milking their cum. Muffled cries around the oral tentacles were the only sounds the brothers could make.

These writhing creatures were delicious! Argent flames of rich compounds permeated the surface receptors of the monster. As much as it was able the sudden infusion of serotonins and dopamine from its victims brought the monster to juddering pleasure. Its internal chemical factories involuntarily duplicated the molecules which then suffused the blob. Had it been able, it too would have cried out in ecstasy. The monster became a machine, milking the penis of each victim to sustain the bursts of pleasure its respondent chemical manufacturers imitated.

After some interminable time fatigued glands on canine and beast alike meant the pleasure began to ebb away. Around each canine's penis washed a milky-white glob of their semen, held in the orifice by the translucent maw. With disgust the creature realized the fluid contained complicated sugar compounds twisted into helical knots. While the salty earlier fluids had been palatable, these organic molecules tasted disgusting. But the beast mused they must have a purpose – perhaps the fluid was intended for the captives. Peristaltic undulations drew the milky fluids away from the shrinking penis of each canine.

In the afterglow of the most intense orgasm of his life, Trent watched bemused as his brother's ejaculate was suckled away. At the same time he felt undulations around his shrinking penis and guessed his cum was also being vacuumed. He watched the liquid flow in globs through translucent pipes around his brother's waist, then down. Half way between their bodies another tube of white globs crossed. Trent mused it was his own semen whisked away. White globs of his semen pulsed up the clear tube toward his brother's face. With a startled gasp he saw the globs of his cum pulse into his brother's mouth. At the same time salty sweet fluid flooded against his tongue. Tendrils around his muzzle tightened, leaving Trent with no option but to swallow his brother's ejaculate. He'd never tasted semen before – his own or anyone else's. Expecting something acrid instead the taste was walnutty like the subtle flavour of soft cheese. His bother likewise swallowed Trent's ejaculate down. They looked at each other and raised one spotted eyebrow. It had been undeniably weird but neither brother was harmed.

Kyle had just drunk his brother's cum. For the first time in his life something other than his own hand brought him to orgasm. And for the first time in his life he'd swallowed another male's semen – his twin's. It tasted… okay. Quite good, actually. His twin watched him with the same inscrutable expression he was probably giving his brother. He was kinda sorta glad it had been his childhood friend's semen. Maybe his brother was more like him than he had given credit.

In the hot-tub the monster stirred. It definitely needed to experience that influx of pleasant chemicals again. But it wasn't so keen on the organics the canines spewed from their tentacles. Perhaps there was some way to… With a flash of insight the monster realized the captives were perfectly constructed for exactly that configuration.

Prehensile limbs manoeuvred Kyle until he faced away from his brother. The powerful arms moved the two bodies closer together.

Disappointingly Kyle could no longer admire his brother's naked, toned form. He was turned away so the bland privacy screen of the patio was his only view. And more disappointingly he felt the delicious bulge in his rear deflate. A prolonged weird wriggling sensation in his guts meant the whole length of the tentacle was being withdrawn. Kyle felt hollow and empty inside. He hadn't realized how much he'd enjoyed the full sensations until they were taken away.

Trent watched his brother's position being adjusted. As his twin rotated Trent could admire the masculine form as though presented on a turntable. In profile his brother's chest was deep with bulging pectoral muscles. His legs were thick, powerful like his muscular arms. Further around and his back was a taut wall of strength. His solid buttocks looked firm and perfectly rounded. Trent wondered how it would feel to grasp those powerful orbs. The heart-shaped bronze patch across Kyle's rump seemed like a target and the bullseye glistened with lubrication from a departed tentacle. Trent's penis twitched – he wondered how it would feel to press his cock under that cute stubby tail. Maybe it was just the narcotics he was being fed but he found his naked twin to be gorgeous.

The monster was pleased. One of the bodies had already started secreting tiny amounts of the good chemicals. Obviously the blob had correctly interpreted their biophysics. With infinite care the giant monster peeled back the protective tube from the rear canine's pseudopod. The canine seemed to be significantly relaxed, compliant even. Experimentally the monster unwound the bindings from the figure's arms, supporting the canine instead by their legs and a thick limb twined around their chest.

With his arms freed Trent caressed the fuzzy globes of his brother's butt. Muscles leant firmness to the globes but they dimpled under his squeezing fingertips. An obliging tendril retracted his sheath as he used his thumbs to pull the cheeks apart. Trent pushed his hips forward, sinking his rod into the well-lubricated hole. His brother's anus was warm, silky as velvet and felt perfect. This was it – Trent was actually losing his virginity… with his twin brother! Involuntarily the young man humped his hips to increase the stimulation along his shaft. Warm clenches around his shaft brought jolts of building pleasure to his abdomen. As he fucked his brother his knot grew. At first it slipped easily through his brother's puckered ring. But after a few moments each withdrawal and subsequent re-entry stretched Kyle's sphincter. Trent's hips became a jackhammer slamming into his brother's buttocks with a loud slap. Trent's dangling ball-bag slapped against his brother's scrotum. Just before his knot grew too large Trent hammered mightily forward, forcing the swollen bulb into his brother. He saw his brother tense suddenly, then relax. Locked inside him, Trent's knot tugged delightfully with the abbreviated strokes he could now do.

To Kyle it felt like new tentacles were caressing and squeezing his buttocks. Another thin tendril poked at his sphincter and he relaxed in anticipation of delightful full sensations he'd felt earlier. The tendril pushed about eight inches into him, then withdrew. Slightly thicker and longer it pushed back in, then withdrew again. Several times the tentacle entered and pulled back. Strangely as it reached full depth, a heavy bulk pressed against his butt-cheeks. The impacts came faster as the diameter and length of the shaft increased. A bulge along the shaft repeatedly stretched Kyle's sphincter as it pushed in and pulled back. Kyle relaxed as much as possible, but the bulge was growing too large to comfortably pass through his ring of muscles. With an almighty shove the giant bulge popped through his taut sphincter and lodged inside him. Kyle jerked at the sharp sting of being overstretched, but as the bulge nestled against his prostate the young man relaxed. Heavenly fullness sensations grew inside him. Short tugs by the tentacle pressed the bulge repeatedly against his prostate in ways that make his cock tingle and throb. Hot fluid jetted from the tip of the tentacle. Several long bursts flowed into Kyle's guts. This new tentacle was heavenly, pressing and filling the young man in exact ways he loved. A heavy mass pressed against Kyle's back and two muscular tentacles encircled his chest. With a start Kyle saw bronze fur along the limbs around his chest. With sudden awareness he realized his twin's knot was locked into his butt, his twin's cum was flooding his bowels. And he'd lost his virginity to his twin brother. Trent's knot pulsed inside him in delightful ways.

Through surface receptor pseudocells the monster absorbed wonderful chemical soup. Both the canines were exuding delicious cocktails of stimulating feelings. Sharp, hard and tangy chemicals oozed from the rear body, similar to earlier. Strangely the front body released a warmer, softer blend. Even though the front body wasn't expelling those disgusting organic fluids it still produced copious quantities of rich sensations. Flavours mixed in perfect complement. Spicy notes from one augmented soft, subtle undertones from the other in a gastronomic symphony. The monster basked, washed in ebb and flow of a dynamic range of chemical flavours. This configuration was perfection upon perfection.

The brothers stayed locked together for a half hour. Trent filled his twin with his cum in spurts, while Kyle savoured the sensual knot pressing against his prostate.

Eventually Trent's knot deflated. For a while he hugged his twin even as his penis slipped free.

Fatigue ached in the monster's limbs. It took extravagant resources to lift and manipulate two young adult Rottweiler hybrids. But it would persist. The bodies were identical – there was still a reconfiguration to try…

Reluctantly Trent unfurled his arms from his brother's torso as the irresistible tentacles separated the twins. Actions of the monster had become sluggish – it was no longer able to hoist the brothers in the air but allowed their feet to rest on the patio. Weird slithering in his guts meant the tentacle in Trent's rear was falling away. He was treated to admiring his brother's rotating form as Kyle moved to face him. Dogs, Trent had just fucked his brother, losing both their virginity. Would his sibling be pissed off? When his brother was facing him Trent realized Kyle was grinning around the tube in his muzzle. Trent grinned in return and Kyle winked at him. Then Trent's paws were shuffled around as he was rotated away from his brother. A moment later and Trent felt strong paws grasping his buttocks. A thin rod poked at his lubricated sphincter. Trent relaxed to allow the probe to push deeper. Two large hands clutched the canine's hips, pulling him back as the rod pushed deep into his guts. Trent stepped to keep his balance, barely registering how the restraints around his legs and feet had slumped away. He was standing in a puddle of goo. The shaft in his guts retracted and entered in a delightful rhythm. It thickened and lengthened with a growing swelling at the base. The bulge stretched and released him in turn. Impacts of hips against his buttocks and thighs against the back of his thighs meant his brother had started fucking him with instinctive abandon. Trent murmured contentedly around the tube in his muzzle. That slight action moved his jaw enough that the oral tendril slipped free, slapping to the patio. Tendrils that had wrapped his muzzle snaked down joining the growing puddle at his feet. But Trent barely noticed. He reached back with his paws to his brother's hips, encouraging his twin to fuck harder, fuck deeper.

Loud slaps of flesh against flesh echoed around the patio. Kyle jackhammered his brother until his growing knot popped with finality through the tight ring of muscle. Trent grunted and juddered at the sting of pain but then the knot was pressing him in delightful ways.

Kyle wrapped his arms around his brother's chest, pulling him tight into an intimate embrace. He juddered as the first squirts of his cum poured into his brother. The young canine groaned and shuddered with orgasm, pressing his chest against his brother's back. Unconsciously, lost in bliss, Kyle rested his muzzle on his twin's shoulder. Then when he felt his brother's cheek nuzzling his own Kyle opened his muzzle to accept his twin's kiss. They locked maws over Trent's shoulder, tongues exploring the other's mouth. Periodically Kyle shuddered as another burst of orgasm wracked him. And his brother moaned in reply as semen pulsed into Trent's depths.

The monster was exhausted. It struggled to retain shape but a mass of its bulk slumped into a jellied puddle around the canine's paws. Through that bare contact it could taste the harmonic perfection of the twin's coupling. Treble notes and bass rumbles of flavour were carried by a harmony of bliss. Tired, drained, the blob basked in the sweet melody produced by the twin canines.

With the fading echoes of the tune drifting away the monster felt its own consciousness precariously failing. Making one final supreme effort of will puddles of translucent pink goo congealed and slithered up the walls of the hot-tub. At last the monster slumped, falling asleep in the warm container.

A month later…

“Did you feed Spot?"

“Oh, yeah… I thought he might like fine dining, so I gave him your first pressing Beagles albums."

“Ha! Dork. Y'know, I was thinking… when he finishes budding off we could release his offspring into the ocean. They could clean up the plastic waste."

“That would certainly make beach-day more interesting…"

“True... Hey, wanna spend some time in the hot-tub with me?"

“Sure thing! Love ya, bro."
