A Very Good Boy
Quick vore and smut story I wrote after being somewhat disappointed to discover a lack of Cerberus related stories.
Cerberus sat in front of the gates to Hades, watching the milling crowd of shades attentively. Or rather, at least one of the massive dog's heads was always watching. The advantages to a three headed watchdog are many. Cerberus took his work seriously - guarding the realm of the underworld and ensuring none escaped - living or dead.
Still, it was good he could let his heads wander regularly. The gloomy cavern was rather dull to look at, and escape attempts were rare. At present, Cerberus' right head was daydreaming, staring off into the distance. Right was always a little more excitable than the others. His left head was leaning down, growling at a couple of shades who had moved too close to the mastiff.
Cerberus was more than twice the height of a man and powerfully built, so the merest hint of a growl sent the curious souls scurrying back into line.
His middle head was the more responsible one, so right now he was scanning the crowd, looking for any shades moving the wrong direction or causing a ruckus. So it was that the middle head was the first to spot the pair of harpies flying towards him from the left.
Cerberus came off his haunches, all three heads focusing on the demons approaching. The hound of hell had a working relationship with the other monsters of the underworld. They avoided him and he did whatever he wanted. So he was annoyed when these harpies flew right up to him and started squawking, pointing frantically to the left along the wall.
Left growled as one of the bird/woman creatures started to fly around his head. He snapped forward as it came in front of him, grabbing a wing in his teeth. The harpy screeched as it was yanked back into the waiting maw of an angry dog.
The other two heads watched impassively and a little jealously as Left made quick work of his meal, rolling the monster around in his mouth before dispatching it with a gulp. He finished by spitting out some feathers at the remaining harpy.
It backed up, but did not stop its insistent screeching and pointing. Cerberus growled a little, but the message was clear despite the lack of speech. Something needed his attention along the wall. He got up, stretching. As he began walking he felt the devoured harpy reach his stomach, allowing all the heads to enjoy the sensation of a good meal.
Cerberus picked up his pace, having no trouble with his wiggling belly. He was only ever called for one thing - escape attempts. Attempts, because no one escaped. Not from him, not without the express permission of Hades.
As he rounded a curve in the wall, the harpy screamed, pointing again. Cerberus saw what had excited the demon. Escapees. Several were clambering down a rope from the high wall above, but a group of a dozen or so were waiting at the base. As they saw the huge black mastiff barrel towards them, they tried to flee.
Foolishness. He ran forward, but stopped short. He raised his heads, all three sniffing. The land of the dead was not very pleasant smelling, but it was uniform. Except right then, Cerberus smelled sweat. He looked more closely at the crowd.
Yes, there were mortals there! About an even mix of shades and humans, although the one looked to be a satyr. The hound of hell started to salivate, all three heads licking their lips simultaneously.
The big dog leaped forward, landing on a few shades. Those just puffed away. He couldn't eat them anyhow. As the others stumbled back, all three heads lunged down toward a different human and grabbed them in their jaws.
When the hound of hell stood, he had three wriggling, bulging lumps in his throats, slowly making their way down to meet in his stomach. Cerberus figured the easiest way to prevent escapes or rescues by mortals was to kill them, and what better way than this?
The lucky few remaining had only run a short distance down to the river Styx. There, they watched helplessly as the harpy pulled their little raft away from the bank. They knew the river Styx was death and worse to anyone who fell into its waters. Trapped, they turned to watch as Cerberus finished off a few other shades before turning to the rope.
One mortal still clung there, trying to haul himself back to the wall. He looked down, terrified, as Cerberus came and sat patiently at the base. All three mouths opened, yawning wide. The man shut his eyes, praying. He couldn't really go up. He'd be going into Hades, and that was as good as dead. And he obviously couldn't go down.
Cerberus' left head solved his conundrum. Annoyed with waiting, he lunged forward and grabbed the rope in his jaws, yanking and shaking it to dislodge the man. Surprised by the motion and already tired, he yelped as the rope ripped from his hands. He flipped around once and had time to look down and see a waiting throat below him.
Cerberus' middle head neatly caught the snack. He savored the flavors, real and pungent, so different from harpies and hellhounds he normally ate. Finally he swallowed, content with the knowledge he was doing his job well.
The onlookers at the river bank watched as the hound of hell finally turned back to them. With nowhere to go, several fell to their knees, pleading for mercy. Cerberus wouldn't have listened if he had understood, but their surface tongue sounded like blabbering to him, so he just started eating.
One by one, his heads lowered and scooped up a human, tasting and savoring them. They didn't resist anymore, their only method of escape being gone. Cerberus took his time with these, enjoying a rare treat. His heads turned toward each other, and gulped in unison.
When they looked down, there was only one mortal left. A satyr. The right head lunged forward, but the middle head blocked him. A thought had occurred to the big dog. The satyr was on his knees, head bowed. And Cerberus had another hunger as he stared at the bipeds furry hindquarters.
The hound of hell was smart. He had learned much in his immortal life. These satyrs were followers of the hedonist god, Dionysus. He was far too large for a mortal, but maybe a satyr trained to such exploits…
His heads were in alignment. An escape attempt stopped, a good meal, and a solid fuck would round out the occasion. He growled at the satyr, feeling himself start to spill out of his sheath.
The satyr looked up at the growl, surprised not to be eaten already. He looked right up at the emerging pink tip of Cerberus' cock unsheathing between his legs. The mastiff watched curiously. Even the monsters he fucked had been a little scared to see a couple feet of doghood reel out, almost as thick as a human torso.
And yes, the satyr looked scared. But Cerberus smelled the change as he also became aroused, and three sets of eyes watched a hint of pink appear in the goat mans lap.
Cerberus was smart, so he knew no amount of practice or desire would overcome this size difference. He was going to eat the satyr anyway, but he did want to get his whole cock in first. So the middle head leaned down and engulfed his head in his jaws, then walked towards the river.
Predictably the satyr panicked, but the other two heads barked and nipped at him till he stilled. And Cerberus went to the Styx and dipped the goat man in. He thrashed. The pain was incredible. But his head was out, and more importantly the satyr had recently assigned himself the goal of being fucked by the hound of hell, so he held to his purpose and was not burned away by the river.
When Cerberus pulled the satyr out, dripping, he spun around and tossed him against some rocks. His own cock was hard now, and he didn't want to wait. The satyr was still groggily trying to recover his bearings when a big nose nudged him over onto his stomach.
Before he could orient himself, he felt something burning hot on his back. It moved down, and he felt the tip. He gasped, then had that driven from him as Cerberus thrust. The big dog growled in delight, all three heads lolling back with tongues out. So unbelievably tight, and yet he didnt split.
The river Styx had made the goat man all but indestructible, much like Theseus. So it was that the satyr felt two feet of cock enter him, shoving aside all his organs in the process. But he did not die, and he actually did not feel pain. Just pressure like never before.
The poor thing's prostate was an afterthought at this point, considering the dogs tip was prodding his lungs. Cerberus was right however. The satyr was a student of Dionysus, and the mere fact that he was being fucked by the dog that guarded the underworld, taking a cock thicker than him, had him more aroused than he'd ever been in life.
Cerberus only cared about the satyr enjoying this in that he didn't try to escape, so he quickly resumed thrusting. The big dog pounded the goat man into a rock, his whole body rocking, full belly wriggling on top of the satyr. He groaned and growled his pleasure.
It had been ages since Cerberus had a good fuck like this. He cut loose, each head dominating in turn. The left growled and thrust faster, wanting the satyr to really feel it. The middle head resumed a steady pace and started grinding his knot in. The right head stopped waiting and decided to jam it in.
In the midst of this, the forgotten harpy flew over, squawking. The simple minded demon did circles around the mastiffs head, pointing up at the wall. The middle head glanced over, but the shades were retreating. Not his problem then.
When the harpy tried to land on his snout to direct him, the middle head lost his temper and snapped forward, gulping the harpy down. The right head remained oblivious and finally got their knot in at the same time. Both the right and left heads lifted up and howled, the mournful sound echoing through the underworld. The middle head was busy swallowing harpy of course.
The satyr wanted to howl too, but he was occupied as torrents of dog cum flooded his body and came gushing out of his mouth. With the knot sealed to his indestructible ass, there was only one way to go. Cerberus humped forward several times as his orgasm continued, dragging the goat man turned cock sleeve across the ground.
Finally it started to ebb. Cerberus panted, all his heads drooping. The right one leaned down and inspected their toy. Still alive, thanks to the blessing of the Styx. Well, couldn't have that. The dog was allowed his diversions, but he knew he couldn't let anybody escape.
For now, he began walking back to his spot at the gate. His hard cock swung side to side, an exhausted satyr impaled on the end and leaking cum. Cerberus felt his belly wriggling still, although it was slowing down. All his exertion would not have made his dinner happy.
Cerberus returned to his post and sat on his haunches, presenting his pride to the crowd of milling shades. Shame was a foreign concept to the dog. After a few minutes, he felt the satyr stirring. The motion threatened to stimulate him again, so the right head leaned down, and with one motion, swallowed the satyr right off his cock.
The other heads sighed in unison, returning to their watch, oblivious of the horrified stares of shades. A good day, all told. A full belly, empty balls, and his reputation as the inescapable watcher of the gates renewed. He was, he decided, a good dog.
