(This will be a MxM story, has some bestiality, transformation and HumanxFurry sex. Let me know if I can improve my writing in anyway with constructive criticism. If you want a sequel let me know, I kind of did this off the top of my head. Hope you enjoyed because I know I did while writing this. Thank you for reading)


It was a normal day like any other. Lars had just finished class and was heading back home to his apartment. Axel would be excited and happy his owner was returning home. The German Shepherd was waiting at the front door patiently, his ears flicked and he tilted his head slightly when he heard a car pull up. The sound of the car door shutting made the dog's tail wag and the steps he heard made it lash about faster. Axel heard the key's jingle and saw the doorknob move. Once the door had opened and the man stepped inside the pet took no time to jump up to greet his master. His paws rested on Lars' shoulder's and he licked the human's face. "Hey Axel!" The animal kept licking and wagging his tail. Lars stood around 5 feet 9 inches and weighed roughly 150 lbs. His hands rand up and down Axel's back and he closed his eye's so no saliva got in them. Once he felt the licks go away he opened one eye to check. The light blue eye looked into brown eye's and Lars' smiled. "I hope I didn't keep you waiting." Axel hopped down and his tail flailed about as he was petted further. His owner placed his backpack down and took his shoes off. He looked in a nearby mirror to make sure his dirty blonde hair wasn't soaked in spit, the short hair remained dry, his skin slightly tan.

Lars moved to get something to drink from his fridge, the small apartment had a tiny kitchen and living room, a single bathroom and bedroom. The man heard the clicks of Axel's nails behind him as he walked across the tile and he looked down. "You hungry?" The dog just sat down and his tongue lolled out as his tail swayed behind him. "I will take that as a yes seeing you are always hungry." Lars grinned as he grabbed the food for Axel. He filled the bowl up that was in the corner of the small kitchen and he made sure his pet had enough water. Once that was taken care of he finally opened the fridge and grabbed a bottle of water. Opening it he took a few gulps and heard Axel crunching on the dog food. He stroked the dog's fur softly and moved to the living room. He sat down on the couch and turned on the TV he had. Basically the only two things he could fit into the space provided but this was all he could afford. It might have been cramped but it was cheap. Moment's later he felt Axel hop onto the couch and felt the furry head lay down on his lap. His finger's combed through the soft fur and he felt licks on his other hand. "How was your day Axel?" Lars asked and he heard and felt the tail hit the couch. He knew he wouldn't get a verbal answer but he always liked to treat Axel like an equal even if he was a pet.

The German Shepherd moved to sit and licked the male's cheek. This was his life. School, work, and Axel. Everyday it was the same thing, go to school, go to work, come home and relax with his best friend. Some times it grew boring but it was a good life. Lars petted Axel's head and he placed a kiss on the god's nose. The man spent a few hours watching TV before he decided to head to bed. Luckily he had no homework for the night. He went to his bathroom, the bland room was tiny but it had everything he needed. He took a quick shower and changed into some clean boxers. Moving to his room he sat on the bed, which it and only a dresser could fit in. Axel came in soon and plopped onto the mattress. Lars laid down next to Axel and pulled the covers over them, though he knew his companion could keep him warm. The next morning he was awoken by wet licks to his face, like usual. The man groaned and turned over but Axel just moved so he could continue to barrage the human's face with licks. Finally he opened his eye's and gently ran his hands over the pet's fur. "I'm up." Lars spoke quietly as he stretched. He sat up slowly and Axel laid his head on the man's lap. Once he was fully awake Lars crawled out of bed, Axel following quickly behind. The man went to use the bathroom and then showered. After that he fed Axel and cooked some breakfast before getting dressed for his day. He petted the dog and kissed his nose before he left. Another day like usual.

Unlike yesterday Lars went to the gym for an hours after school, like he did on his days off from work. He waited to shower until he was home. He was greeted by Axel who didn't mind licking the sweaty face. Lars fed Axel and headed to the bathroom to shower but the dog followed this time. The man stripped down out of his clothes. Axel moved to the clothes and sniffed them and looked up to see his master naked. His tail swaying behind him. He gave the man's butt a lick which made him jump. Looking back Lars sighed. "Don't scare me Axel. You already ate?" The dog sniffed his owner a few times and licked his leg. Which made shivers go up the human's spine. To the canine the male's scent was wonderful almost intoxicating and he loved when his owner came home smelling like this. It made his hormones kick in each time and made his gut warm. Axel panted softly as he sat down. Lars never minded if the pet was in there while he showered. The man bent over to turn on the water and he felt the dog's nose go in between his ass cheek's. Something that had never happened before. He felt a lick and another and soon Axel's was licking away. Lars tried to move and stand back up. "H-hey Axel what are you doing?" Yet the soft rough licks felt odd and pleasurable. A soft unwanted moan left the human's lips and the canine prevented him from getting up by mounting him. The owner was bent over the side of the tub pinned down with his ass up, his hands on the bottom of the shower tub combo to support himself. "A-axel stop!" Yet it was too late as he felt the wet tip poking at his tight entrance. Was his pet really erect?

Lars felt Axel bite his neck to keep him into place then he felt the tip push inside. He bit his lower lip as he felt the muscle stretching as the cock slid inside. It hurt, a lot and he could tell Axel had a nice large dick. The man felt it penetrate him deep and within a few seconds it was going in and out fast. He almost drew blood as he bit his lip and Lars felt pain with each thrust yet he couldn't do anything as the dog overpowered him. Yet there was one spot where Axel hit that sent some pleasure into his body. Each time that spot was touched he felt himself grow more hard. He could feel pre oozing inside of him as Axel pounded his virgin ass, the tightness and pleasure felt amazing to the pet. His knot slowly began to form as he rutted into the other harder and faster, his ears pricked as he heard a soft moan leave the human's lips and the scent of arousal hit the air. He could almost taste it and the pre that was drooling from his master's now erect cock. Lars felt the knot growing and bumping against his entrance and with each thrust he felt it trying to break past the tight barrier. The man's face was red from embarrassment as he moaned out. The large canine cock stretching him and pleasing him. After a few more moments he almost cried out in pain as he felt the know push past his entrance and he felt the warm seed rush inside his hole. Axel licked his master's neck as his legs shook, his semen filling the other, his knot preventing any from leaking out. He felt Lars' ass tighten and he smelled the cum that shot out of the human's cock It spurted all over the floor and the side of the tub as his body shook.

"Axel you can get off now." The dog tilted his head and tried to pull out but the knot wouldn't budge. "Great I forgot about that." Lars groaned as he felt pain with each tug. "Stop stop stop. Just.. let it go down." The dog licked the man's cheek and his tail flailed about. It had always been a dream to take his owner and he finally acted upon it. The pleasure was fantastic and he knew Lars enjoyed it too because he came. Would they do this more often or would this be a one time thing? The dog didn't care as long as he got to feel this happen once. After a few minutes of being connected to his master the dog's knot deflated. He pulled out and stepped back, the man's ass was open and dripping his semen out. God it was a hot thing to see. Lars wobbled to his feet and didn't say anything as he turned on the water. The German Shepherd tilted his head as the human stepped into the shower and didn't look or speak to him. Was he mad? Axel would give it some time but he did moved over and sniff the male's semen on the floor. He lapped some up before trotting out of the room happily. His tail swaying high in the air behind him.

Lars cleaned himself and tried his best to clean his abused hole. It was sore and hurt, he was shocked there was no blood or ripping. Once he was finished showering he got out and dried off. He cleaned everything up and headed to the living room, wincing with each step. Sitting down he felt Axel lay down quickly, his hand running down the pet's back. He couldn't be mad, after all he was a dog and they did act on instinct but he wasn't sure how to react to all of it. It did feel good after awhile and the rush of being full of the knot is what sent him to that peek. He sighed and turned on the TV. Maybe he just wouldn't think about it but it was hard seeing as just sitting down hurt. After a few shows he got up and cooked some dinner, Axel finally eating his food as well. Lars went to his room and his felt the dog at his heels. The human grabbed his backpack and pulled out his homework, Axel laying behind him as the man worked on the assignments. Once they were done he decided to go to bed early so he put everything up and crawled into bed. Axel laying with him giving soft licks to his neck and ear. Lars couldn't help but have his thoughts wander to earlier. Just the thought of the orgasm was getting him hard again and he rarely had time to release any sexual tension.

He laid on his back and Axel rested his head on the man's chest giving soft licks and his tail wagged when he was petted. Though he could smell the male growing aroused which only made him aroused again. The pheromones that left his owner smelled wonderful just like the musk from earlier. He began to pant softly and Lars looked down at him. Was he getting hard too? The man thought as he ran his hand down the canine's belly and back up, each time inching closer to his pet's groin. Was this even okay? After all it was bestiality but Axel was his best friend, and they both seemed to enjoy earlier. He felt the wet tip as his hand brushed lower and he watched as Axel's ears flicked. He moved his hand lower and grasped the hard cock making his dog pant harder and lick rougher. With his other hand Lars began to jerk his now hard cock, pre rolling down the shaft. Axel bucked into his hand and moved his licks lower, his head going under the covers. The canine moved lower and lower until his tongue was lapping up the pre making the human moan out and more pre cum dribbled out. "A-axel." Oh that moan sounded nice to the pet's ears and he licked more, the man moving his hand away now as he jerked off his dog and the dog licked his hard dick.

After a few minutes of this he grew curious. What would a dog's dick taste lick? He gently moved the German Shepherd on his back who's tail was wagging and his cock throbbing at full mast. Lars gulped as he moved over the pet so his erection was over Axel's muzzle. He moaned as he felt the licking resume and he gave the red flesh a test lick. The man's tongue brushing against the moist head and more pre shot out. It tasted musky and bad but also good at the same time. Lars licked down the shaft to the swelling knot and sucked on the bulb some, he heard Axel pant more and his licks grew sloppier. The human licked up and down the hard canine cock and pushed it into his mouth, his taste and smell being overwhelmed by the musk yet he didn't stop. The male sucked and licked the thick cock in his mouth and played with the dog's balls, the tail moving fast and he caught glimpses of the tight tailhole. His middle finger running over the soft, tight, warm muscle which seemed to open up for him. Sliding his finger in he felt Axel cum and the semen burst out through the sides of his mouth. He gulped and tried to swallow as much of the seed as he could and pulled off the member with a pop.

Axel moved to lick at the man's entrance some and his cock never softened. He felt his gut tingling and he licked away. Oh how much he wished he could talk to Lars, to be able to play with his ass other than licking and fucking. If only he could beg for that large dick to penetrate his tight virgin ass. Lars tried to pull his finger out of his pet but it seemed it was pulled in more and more, the warm insides clamping down on his finger. Everything became a blur for Axel, his body growing warm and slight pain ran though his joints as his body shook. His owner pulled his finger out finally and rolled over onto his side. He saw how Axel was acting and he grew worried he did something wrong. "Axel? Boy? Are you okay?" He asked as he moved over and ran his finger's over the fur on the canine's head. The dog felt his bones snap and shift and Lars watched as the body changed, becoming more human. His eye's wide as he watched the strange events happening. He looked back at Axel. "Axel what's going on?" A sad tone in the question as he feared his best friend would die. Yet moments later when it was all over the German Shepherd looked up at Lars who was now crying. "I am okay, don't cry." The pair was shocked as Axel spoke and he held up a furred arm. Looking down at his knew body he tilted his head. "What?" Lars just stared at the other for a moment who sat up. "Did... did I turn human? I.. I can talk and my arms and legs are like yours master. But I am still furry, and have a tail and paws." The human sat there a moment. Did his dog just turn into a furry? Those things didn't exist though. They couldn't. His hand ran up the muscled abs and chest and to the furry's head. "You're.. a furry." Axel tilted his head. "A furry?"

"A humanoid animal, you are like a human but still part animal. How could this be? This is scientifically impossible." Axel looked over his new body and ran his hands down it. His cock still covered by a sheathe, thankfully. "Lars..." He spoke softly and looked at the other but before the man could speak he pulled him into a kiss. His tongue roughly invading the human's mouth. "I.. my wish came true?" Lars looked at Axel. "Wish?" The furry nodded. "I wanted to be able to talk to you. To be able to beg.. beg for you to take me. And for me to be able to pleasure you in many different ways. You're my best friend and I.. I want to be mated to you." The human blushed and felt the other nuzzle his neck, a furred paw gliding down his chest and stomach. He shivered as he felt his now semi hard cock being touched. "Lars let me please you like earlier." Lars was shocked almost paralyzed. He was laid down and felt licks go down his body, he watched as Axel moved closer and closer to his cock. The canine grasped it and licked the head and shift some before sliding it into his muzzle. He sucked and licked the meaty dick as it began to grow hard again. Lars felt his back arch and he moaned out as his hands grasped the other's head. PRe oozed out and he felt the other paw teasing his entrance. He a gasped as Axel began to finger him and he almost came just from all of this. "Axel!" Lars moaned out. The man felt his member throbbing in the warm wet muzzle and the rough tongue going up and down the shaft happily. The pet pulled away though and moved over the human's chest, his fully erect penis was now even larger. "Suck me Lars. I love your tight mouth." The male went to speak but he was soon gagging as the meat pierced his mouth. His hands held those furry hips as they bucked in and out. His tongue swirled against the tip and after a few moment's Axel pulled out, Lars felt drool run down his face.

Axel moved so his ass was facing his owner. "Taste my hole Lars." He spread his rump to reveal his tight tailhole. The muscle was twitching and throbbing. The man moved forward and gave a slow lick making Axel growl softly. It tasted musky like his cum and cock and Lars licked hard. Soon he was rimming the other and his hand moved to stroke the plump cock. He gasped and moaned as he felt Axel stroking him. The room filling with their scents and moans. After Lars got enough spit on the entrance the German Shepherd moved to lay down, spreading his ass. "Breed me, mate with me Lars." The human gulped and moved to get behind the other. He rubbed the cum covered tip of his dick against the warm hole. "You sure?" Axel nodded and the male pushed in. He went slow and once he was fully buried into the other he kiss the canine's neck. The furry pushed back against his owner who now was slowly thrusting in and put. "Fuck me hard Lars, I want it rough." Despite the pain it felt amazing to be connected this way with Lars and Axel wanted to be pounded like a naughty little pup. Lars slowly picked up in pace and depth soon his cock pounded the tight tailhole. The two moaned and the furry growled softly. He felt Lars pull out and whine but his hips were grasped as he was pulled into the other's lap. He sat down on the cock happily and bounced timing it so the human's thrusts and his bouncing made them collide hard. "Fuck... Lars harder. I am close." The man grunted and looked at the swollen knot. He kissed up and down his pet's neck and shoulder. The man's hand moved and gave the knot a squeeze which made Axel howl, his hole tightened and he came. His semen rushing out and the tightness made Lars breed his pet's asshole. His seed flooded the other's insides and he felt his cock throbbing as it was milked.

Axel felt a slight difference after he came as he felt his prostate being hit as Lars didn't stop thrusting and only pounded hard as he came. The furry moaned and growled and his cock twitched as he though he came a second time. Liquid squirted out but soon he smelled piss as it gushed from the tip of his member. Did he just piss himself? Lars watched as his pet came a second time? Wait no he pissed? Did he just make Axel squirt? The man though only female's could do that. He watched the liquid cover and mix with the cum and the sheets slowly were soaked with the two liquids. Once his orgasm was over Lars fell back and so did Axel. The human's arms wrapped around his best friend and the laid on there sides after a moment. "Don't pull out Lars." The canine begged as they spooned. "I won't" Lars reassured and pulled the other into a kiss. "I love you Lars, my master, my mate." This made Lars smile and blush. "I love you too my pet, my mate, my best friend." What was going to happen now? Neither were sure but for now they just wanted to bask in this new found relationship from best friends, owner and pet to mates.
