Jeff clicked through and set the duration for a week. He was feeling rather nervous that the Chronivac might pick something that would be hard to change out of . As he clicked submit, he looked over the rest of the settings and felt less nervous as everything seemed to be in order. The Chronivac let out a loud yet cheery ping as a a single word popped up on the screen.
"PET"
"Pet huh? I guess it wouldn't be too bad being some form of animal for a week." Jeff thought. The Chronivac began to make a whirring sound and let out another cheery ping as the screen lit up once more. "REALITY SHIFT NEEDED, REALITY SHIFT ACTIVATED, CHANGING ENVIRONMENT". Jeff frowned a little, becoming nervous as he read the screen. Suddenly Jeff's room began to shift and warp around him. His full sized bed shrunk and shifted, becoming a large dog bed. The black and grey checkered sheets he had used on his bed now became the pattern of the dog bed, the large, blue comforter transformed into the interior of the dog bed.
"Ah, guess I'm gunna be a dog for a week after all." Jeff let out a breath and thought for a moment as he watched his room changed around him. "Wonder what kind of dog I'll become? A Golden Retriever could be fun. Maybe a husky, or a pittbull?" Jeff watched as the figurines of comic book and video game characters that adorned his room shifted and changed into squeaky toys.
"Oh man! Those were expensive!" Jeff sighed. "Well, it's just a week, it's fine." Jeff said as the walls shifted and changed, going from all white to a steely grey colour, large black paw print stickers began to appear along the walls.
"Man, the Chronivac is really making sure I'm a spoiled pup huh?" Jeff laughed as he looked around his room, seeing the last of the changes. His face suddenly drained of colour as he watched one of his batman figure change into a large, 10 inch dildo, with egg sized balls attached. "WHAT THE FUCK?!" Jeff yelled as he looked around the room, noticing that some of the other figurines had changed in a similar manner. Jeff rushed over to the Chronivac and checked the settings, the word "PET" was still flashing in the corner of the screen. "WHAT KIND OF SICK THINGS DOES MY DAD WANT TO DO WITH A DOG?!" Jeff thought as he began pressing the large CANCEL button over and over again. Words popped up onto the screen.
"PROGRAM CANNOT BE CANCELED DURING REALITY SHIFTS." Jeff began to sweat, pressing the cancel button in desperation. Suddenly Jeff's computer chair began to shift and change, becoming a large, black blob for a moment before reforming into a strange sling hanging down from his ceiling. 'NO!" Screamed Jeff before the Chronivac let out another loud yet cheery ping. Jeff turned his terrified eyes towards the screen, reading what just popped up.
"REALITY SHIFT CONTINUING, PHYSICAL SHIFT ACTIVATED, CHANGING SUBJECT, SUBJECT JEFF." Jeff began to slam his fists down onto the keyboard in desperation, as a bright light flashed from the Chronivac screen. Jeff felt his body tense up for a moment, his cloth disappearing from his body. Jeff couldn't move as he watched his body begin to change. First his 4 inch, uncut, flaccid cock began to tighten and shrink, changing into a fleshy, canine like sheath. Just like his cock, Jeff's balls tightened, but instead of shrinking his balls began to swell. He tried to hold back a groan as he felt his once walnut sized testicles grow and swell into chicken egg sized balls that were pulled tight against his body.
As Jeff moaned he felt his tongue begin to flatten inside of his mouth, his teeth changing becoming something halfway between human and canine. All Jeff could do was grunt and whimper as the changes continued. His ears began to stretch out become slightly pointed, something between canine and human. His arms and legs began to shift as his spine changed. He fell onto all fours, panting, his canine like tongue lolling out of his mouth as he couldn't hold back another moan, the changes feeling more pleasing than painful. He felt a wave of pleasure throughout his changing body as his arms and legs became more toned and muscular as they took on more of a canine shape, his hands and feet making a snapping sound as they became paw like appendages. Jeff groaned loudly as he felt a nudging at the base of his spine, a small, nubby tail sprouting above his now swelling ass. Jeff's cock began to stir within it's sheath, a throbbing canine cock popping out, knot and all as pleasure continued to run throughout his shifting form. Jeff's moans turned into pants and whimpers as his vocal cords changed into something more dog like, whining as his ass continued to swell, becoming a perfect bubble butt, just muscular enough with a nice layer of fat over top to give it just enough jiggle. Jeff's chest began to shift and swell, his once flat chest growing a bit of muscle, his pecs becoming slightly toned, just enough so you can see some muscle definition. As his pecs finished their transformation, Jeff's slightly flabby stomach tightened forming into a softly toned four pack. Jeff's new cock leaked a steady stream of pre, his physical transformation now over. His form now changed into a mixture of human and canine. The perfect pet.
The Chronivac pinged again, but now Jeff was unable to look up and see what was now flashing on the screen. "REALITY SHIFT CONTINUING, MENTAL SHIFT ACTIVATED, CHANGING SUBJECT, SUBJECT JEFF." Jeff panted, his mind starting to come back into focus from the bliss of the transformation. Jeff shook his head and his eyes widened as he looked down at his strange, new, paw like hands. Jeff tried to stand up but was unable to, he began to panic again but before he could let out a panicked howl he began to feel dizzy. Years of knowledge began to flee from his brain. Things he learned in school, all his knowledge about computers, everything about his favorite hobbies suddenly began to drift away. Jeff whined for a moment as he tried to hold on to what was leaving his brain. Jeff's cock began to twitch again as his memories began to alter, his memory of his friends began to become hazy as a surge of horniness began to fill his mind and body. His memories shifted and were now being replaced with memories of being a happy, horny dog-boy. Of laying in sunspots on the carpet, or chewing on his favorite toys, of licking and sucking his Dad's cock. Jeff yelped for a moment. "Dad's cock?! I'm not GAY! I'd never suck dad's...dad's..." Jeff's panicked thoughts floated away, he no longer remembered Mike as his dad, only as his master. He loved sucking his Master's cock. Jeff panted, his new sense of smell now causing him to smell the scent of his own, throbbing canine cock. Jeff laid on his side, lifting his canine leg up as he lost all of his human thoughts and morals and began to lap at his own, hard cock with his new, flat, canine tongue. As he did so, his memory of Mike began to change even more, the memories of how Mike Looked. The Chronivac let out another loud and cheery ping as Jeff released a massive load down his maw as his mental changes came to a stop. Jeff panted, a blue collar appearing around his neck, a bone shaped tag with the name JEFFY appearing on it. "REALITY SHIFT CONTINUING, MENTAL SHIFT ACTIVATED, PHYSICAL CHANGE ACTIVATED, CHANGING SUBJECT, SUBJECT MIKE."
