Man into Male Border Collie Dog Transformation Story | Willing | NSFW | 3rd PoV

Terry and Nicole were a great couple overall. They did have a few differences when it came to preferences on topics. There was one core hobby that only one of them had.

Terry was interested in transformation art since he first launched internet. Over the years he had seen the majority of art of all sorts and types. While browsing art was a fun hobby, Terry had an unreachable dream of actually transforming into something rad.

His girlfriend knew about his transformation passion so to say, but she didn’t mind it. She supported Terry and occasionally shared some “TF” art with him even. The couple didn’t have secrets between each other and so Nicole knew about that little dream or rather wish that Terry had.

There was one thing the two agreed for some time now. They wanted to get a dog and they agreed on getting a border collie at some point when an opportunity would show up. The life is merciless and the time passed fast for the two, there was never the right moment to get a dog.

Until Nicole heard about something unbelievable. The scientists have outdone themselves and created a nanite-based technology that was able to transform people into animals. Their forms that is, for safety reasons there was no way to bend the subject’s minds. The transformed people were changing forms, not mentalities.

Nicole promised Terry a surprise for the next week, when they took time off work. On Sunday evening the two sat together watching TV. “Alright, I think this is the best time to show you what I meant by the surprise. Close your eyes hon…” – She asked. Terry’s eyes widened in surprise, but he momentarily closed them. He chuckled thinking that he was submissive like a dog.

Ironically Nicole pulled out a red collar out of her bag. It had several minor technological details that a normal collar didn’t, but those were well hidden and the collar appeared almost natural. Nicole patted Terry’s knee and he opened his eyes. “You always wanted a dog in our house. We have an entire week to enjoy you being one!” – She said cheerfully and smiled at her partner.

Terry blushed and didn’t know what to say at first. “T-Thanks Nicole! I just- I never roleplayed in real life, I hope I’ll be good enough!” – He said and took the collar, then started putting it on. “Wait! This isn’t a regular colla- Uh-oh…” – Nicole exclaimed worried about her partner, who had no idea what the collar actually did.

He was about to learn first-hand what advanced technology was capable of. “Don’t worry, I’ll do my bes- Huh? Wait, why am I so itchy all of the sudden…?” – He asked confused and timidly scratched his hand, then looked down at it. His jaw dropped. The palms of his flesh was bloating out and forming black pillows of flesh. They slowly gained rounder shape and turned into full-fledged paw-pads with fur growing in-between them. Terry’s nails were starting to darken and push out into slightly curved canine claws.

“Nicole! W-What’s happening to me…? I- Wait am I actually…?” – He asked worriedly at first, but then his confusion and slight fear turned into a brighter mood as he understood that he was changing into a dog somehow. Nicole was unable to speak at first, watching her life partner slowly morph into a border collie. “I- Shit, this is so freaky. Terry, I wanted to tell you. This collar is a highly advanced transmorphic device! I can’t believe I’ll say this, but you’re actually turning into a dog!” – Nicole explained.

Terry wanted to say something, but his tongue spilled out of his mouth in a canine manner. The tongue was lengthening and becoming flatter. His lips were blackening, along with the flesh of his increasingly moist nose. He looked into Nicole’s eyes as his own began changing. “Aww… I didn’t know you could become cuter, but here we are!” – She cooed. Terry felt a warmth in his heart, which was both his love and canine loyalty growing in him.

Terry yelped when he felt his tailbone start to pop and push out. More vertebrae formed and stretched the flesh on his growing appendage. When the necessary muscles formed Terry’s half-formed started wagging wildly. Terry looked back at his tail sticking out of his trousers and blushed harder. “I- I’mhr sorry, can’t helph it!” – He growled out as his vocal chords began shifting.

Nicole tilted her head and sighed happy that she actually bought the device. “No need to be sorry, its natural for good pups like you to express themselves!” – She complimented Terry, watching him shrink in his clothes. She gently pulled shirt off his shrinking and increasingly canine silhouette.

Terry nodded in appreciation and repositioned himself. He was constantly shrinking and getting even thinner as his bones rearranged along with muscles arrangement. Terry awkwardly got onto all fours and as he jumped off the sofa his jeans slid off him along with socks. Only his underwear remained.

It didn’t seem to matter much at this point as Terry’s body was slowly getting enveloped in a fluffy pelage of white and black fur. His tail was continuously wagging, Terry never believed that his dream would come true. He leapt onto his girlfriend and licked her hands with love. Nicole blushed and patted Terry’s head.

She noticed how her partner’s teeth have slowly transitioned from omnivorous human teeth to sharp canine fangs. Terry’s nose was now appearing swollen, because it was becoming canine in shape and it took more space on his altering face. Nicole stroked Terry’s hair and watched it turn into fitting black fur. She was amazed by feeling the soft flesh of Terry’s ears thin. His earlobes were becoming pointier and turning into wary canine ears.

Terry was lost in the transformative haze, he felt so light and cared for as Nicole petted and stroked his growing fur. Terry closed his eyes and just enjoyed the moment. His transformation progressed in the meantime. His tail was now fully developed and entirely covered in mixed white and black fur.

Terry’s bare feet were elongating and turning into canine hind paws. The tiptoes were contracting along with the toes and turning into a more compact alignment, good for swift movement. Paw-pads formed underneath the changing feet. Toenails gradually remoulded into dark claws. Terry flexed his hands a bit as they lost their dexterity and became paws completely as well.

“The process is reversable Tery, besides I’ll take good care of you!” – Nicole added to make sure Terry didn’t have the slightest hint of doubt about his transformation and the overall change of perspective. “I khrow youhr whirl! Aroooooohr…!” – He struggled to say and howled happily. Nicole cooed at that and rubbed Terry’s chin, noticing how his face was pushing out into a short snout already.

Nicole noticed that Terry still had something on him besides fur, his underwear. “Uhm, hon. Do you mind if I’ll take that off you? Don’t think you’ll need it with all the fur of yours.” – Nicole asked politely. “Ohr! Yushr, grhoough ohn.” – He growled out and his heartbeat hastened.

When Nicole gently pulled the loose boxers off his furry groin, she caught a flash of what was happening to her partner’s cock and balls. She gulped and tried not to look. Terry noticed her behaviour and his cock stiffened, tenting his underwear and making it harder to pull off.

Terry whined in bliss as his mushroom slowly turned into a sharp red lipstick of a canine. His ballsack was now entirely covered in fur and the flesh was hugging his canine balls tightly, forcing several drops of pre to stain his underwear. Terry whimpered as he felt his foreskin slowly retreat and turn into a furry sheath, attached to his stomach at its base.

Nicole finally managed to get the boxers off the lust-dazed Terry. His red rocket hanged free now. Hanged was an exaggeration as the shaft was stiff and close to Terry’s stomach, supported by its forming penile bone. Terry yelped in ecstasy as his reddening cock started swelling at the base. His forming knot popped free of the sheath and was on full display.

Terry shivered feeling the cool air against his proud doghood. He felt it throb and he wanted to hump something like a soft pillow real bad, but he was too good of a partner for Nicole. He grimaced and decided to control himself.

Nicole saw clearly how pleasurable the changes were. “Poor pooch. It’s all my fault, you weren’t prepared for all those intensive changes, were you?” – She asked honestly. Terry whimpered and readjusted his stance, tucked his tail between his hind legs in shame. Nicole petted Terry on the head reassuringly.

Terry’s transformation was slowly reaching its end. His body was now considerably smaller than it was before the transformation. It was also decisively canine. His ribcage was slowly becoming rounder and shorter, well suited for running with the lungs it encased. Terry’s stomach caved in slightly and became leaner.

The changes were enough of a distraction for Terry’s shaft to slowly soften and retreat back into its furry home. Terry laid down and rolled over onto his side, splaying out his limbs. His legs were slowly finishing their changes into digitigrade canine legs. His arms were already a neat pair of fore legs.

Nicole smiled and stroked Terry’s side. His tail was beginning to wag every time she did that. Thankfully the changes weren’t painful, Terry embraced and enjoyed them too. It was his dream coming true, becoming a simple, loyal dog. If it would be as good as he imagined it, maybe he’ll even stay a dog forever – He thought to himself.

It was the time for Terry’s head to fully change. His jaws stretched longer and his face was pushed out into a full-fledged muzzle of a border collie. Terry panted happily and growled eager to become a complete dog. His upper head flattened slightly and the forehead sloped down. With one last tug at his snout, his muzzle fully formed and Terry became a black and white border collie dog through and through.

He rolled over onto all fours and looked back at his body. His tail was swaying to the sides wildly. Nicole saw how happy her partner was, but at the same time she comprehended that he just changed species. He became a completely different being and she worried about his mind. Was he still her life love as a dog, when it came to emotions of course

“Terry, bark twice if you’re still yourself in there, please.” – She asked. Terry jumped around and barked twice. Nicole sighed in relief and chuckled. “It’s gonna be hard for me to get used to this, but… Oh lord you make such a precious dog, we’ll manage!” – She exclaimed and hugged Terry.

This was the beginning of a new, unique future for the two. Terry was able to change into both his human and dog form as he pleased and it made the perfect balance for the couple.
