From Superman to Superbitch
Krypto has some fun with Superman after he noticed a strange scent coming from him
Superman becomes a Superbitch.
I do not own Superman and Krypto they are the property of DC the only thing I claim is the events of this story which came from my own twisted mind.
Superman landed at the entrance of his Fortress of Solitude worn out after a day of saving the world from all manner of threats and villains. He had to admit sometime it was just too much day after day working for the Daily Planet than saving Earth, so much so he took two weeks off from the paper and was vacationing in the Fortress away from all the humans leaving most threats to Kara and his friends in the league. That was the plan but there were some threats, however, which only he could handle.
Walking into the living area of the Fortress he stripped down to a tight pair of black boxer-briefs and sinking into his chair. As Superman settled in there was a sound of foot steps as Kypto, the Superdog, comes in and jumps into his lap. Superman laughs as Kyrpto licks his face as he scratches Krypto behind his ears. Krypto settled down in his master's lap as Superman grabs a book and begins to read just to unwind for the night. Settling down for the night he was so caught up in his books that he did not realize Krypto was smelling something changed in his scent.
Putting down his book Superman nudges Krypto off his lap and leads his dog to his bed room flopping down on his huge bed not bothering to use the silken sheets almost falling asleep as soon as his head hit the pillow. Krypto was still wide awake trying to figure out the strange scent coming from his master. After a few moments Krypto found the source of the smell it was coming from underneath that strange fabric that his master wore instead of going around nude like other animals. So as to not wake his master Krypto gently took the fabric in his teeth, for a normal dog this would do nothing as it was Kryptonian fabric, but as Krypto was no normal dog his strong teeth shredded the underwear giving him better access to the smell.
Krypto found the source of the strange scent was coming off his master's ass sticking his nose right in and taking a deep breath as he tries to find the reason for the scent. Superman let out a soft moan that Krypto heard and made him suddenly realize what the scent was for. Krypto had a moment of species memory of the scent of a bitch entering heat to show they were ready to be mounted and a close proximity was now coming from Superman's ass. As Superman way laying on his stomach Krypto had perfect access to his ass and was finding it hard to not react to the scent. Sticking his head in between the cheeks that could crush a steel beam, Krypto stuck out his tongue and began to lick ass hole making the scent more noticeable.
As the scent gained in strength it began to effect Krypto's mind as he began to no longer see the human as his master but just a bitch entering heat. As Krypto licked his ass Superman began to loudly moan and even began to thrust back allowing Krypto's tongue to move deeper into the superbitch's ass. After lubing Superman's ass Krypto stopped and walked forward and began to thrust downward trying to get his cock into the bitch's ass.
Superman woke up as Krypto's cock enter his ass with a scream of pain as his virgin ass was invaded. Feeling the warmth coming off Krypto's fur as well as drool landing on his back; Superman tried to push Krypto off of him thinking it was just a mistake. Krypto, however, did not obey no longer seeing him as his master but a bitch to be fucked so he showed his dominance by bending down and taking a hold of the bitch's neck and growling.
Superman became worried as Krypto bit his neck breaking some skin and giving a growl that conveyed that Krypto would only move when he was finished. Krypto sensing that the bitch had learned his place withdrew his jaws and began to rut. Superman had to bite his pillow as Krypto began to jackhammer him into his bed making him think that it was a good thing that everything in the Fortress was Kryptonian in origin otherwise the bed would have been shattered.
Something strange began to happen as Superman actually began to enjoy being fucked by Krypto as his cock began to harden underneath him forcing him back into Krypto's cock. Krypto let out howl of pleasure as he felt his knot growing as with one hard thrust pushed it past Superman's anal ring locking them together. As soon as he felt Krypto knot his ass Superman felt a flood cum shooting into him. He hazard a look down and was amazed to see his stomach begin to bulge by the amount of cum Krypto was filling his with. Trusting the knot would hold Krypto decided to go get something to eat so he turned around actually striking Superman's face with a foot scratching his bitch leaving a gash. Krypto hopped off the bed forcing Superman to follow after him lest he experience so much pain he nearly passed out. Krypto went to the kitchen and got something to eat not paying attention to the bitch. When he was done Kyrpto began to run around the halls dragging Superman behind him who at some times was literately dragged on the ground.
When the knot finally reduced Krypto's cock came lose with a loud "pop" unleashing a huge load of his potent seed. Superman collapsed to the floor of the Fortress completely worn out as Krypto walked a little a way to clean himself. As he start to clean he suddenly thought why should he clean himself when he had a bitch for that. Walking back to Superman and sitting on his hunches in front of the worn out human's face he growled.
Hearing the growl Superman raises his head and spots the semi-hard dog cock still dripping with a combination of their juices. Tiredly he begins to ask what only for Krypto to push his cock between his lips and leave it there. Superman was half tempted to bite down after what Krypto had done to him but a growl from above made him realized that their power dynamic had shifted. With a gulp of revulsion Superman began to suck Kyrpto's cock clean of their sexual escapades as Krypto put his fore-paws on his back as if Superman was a mat to clean his feet.
After about ten minutes Krypto removed his cock from his bitch's mouth and was pleased at the job and knowing there was only one thing left to do. Standing up Krypto cocked a leg and began to mark Superman as his. Feeling the warm liquid hit him Superman looked up only to receive a face full of dog piss. Superman tried to yell at Krypto only for the Superdog to shift his body forcing the stream to land right in to his open mouth with perfect accuracy. Superman shut his mouth with a clang of teeth but as the stream of piss continued he was forced to smell the overwhelming dominant scent coming form Krypto not to mention swallow the piss that had landed in his mouth.
Superman was surprised as he swallowed the piss on the taste of it making him open his mouth to get more only for Krypto to stop peeing. Feeling a little rejected Superman was about to get up when Krypto turned around and sat on his face pushing it so hard down it cracked even the Fortress floor. Superman now found his face inches from Krypto's ass drinking in the musk from a being who just hours ago was his pet. Krypto, on the other hand, liked having the human in his crack wagging his tail and stimulating the Man of Steel's nipples.
As the soft fur brush back and forth across his nipples Superman let out a moan and sticking his tongue out which licked Krypto's ass. As Kryoto liked the lick he forced his ass down some more brining Superman's lips in direct contact with his hole while his balls and cock resting on the rest of Superman's face. Knowing what Krypto wanted and guessing he would not get up until it happened Superman began to tongue Superdog's ass, stretching his tongue as far as it would go into the tight confines of the dog's ass.
As Superman tongued him Krypto began to grind his ass into the floor deepening the crack while at the same time getting the tongue in deeper. When Krypto was finally satisfied he stood up letting Superman take some deep breaths of non-musk filled air. Krypto than turned around and walked away making sure to walk right on his new human bitch as he left.
Superman just laid there covered in cum, piss, and K9 musk until Krypto let out a commanding back and getting to his hands and knees made to follow.
*A Week Later*
As no one had seen Superman for over a week Kara had gone to the Fortress to check on her cousin. What she saw surprised her as she saw Kal-El trailing submissively on his hands and knees behind Krypto she was about to ask what was going on when she noticed that Kal-El was wearing nothing but Krypto's dog collar. She put her hand to her face in shock and nearly fainted as with a bark Krypto had Superman head down ass up before mounting him. Kara began to suspect some form of mind control except she noticed that Kal-El had become erect and no mind control she knew of would make a person hard if they were not actually aroused.
After witnessing her cousin being fucked by a dog for nearly an hour and plainly enjoying it she decided she would have to come up with a reason why Superman was no longer around anymore, but that would come later as she began to finger herself as Krypto knotted and took his bitch on a walk around the Fortress.
The End
