Mike's feral musk was causing Jeff to get dizzier and more relaxed, Jeff could feel his mind begin to empty as he watched his newly transformed father continue to jerk off. Mike walked closer to Jeff, pressing his new, massive, furry balls against his face. "Take a good whiff boy." Mike said in a deep, dominant growl. In the back of Jeff's mind he knew this was all wrong, but Mike's delicious musk was working quickly on Jeff's poor mind. He buried his face between his father's balls and took in a deep breath, almost moaning at their scent. Mike smiled down at Jeff and made a pleased growl as Jeff continued to breath in the musk.
The very tips of Jeff's hair began to change into a shiny golden blonde and a tent began to form in his pants. Jeff's mind became completely numb and complaint as he nuzzled into Mike's balls more and more, before finding himself using is tongue to slowly like between them. Mike chuckled and used his free claw to pull Jeff's head back by his now completely golden hair. "Save that tongue for the main course." Mike said as he rubbed the tip of his member against Jeff's nose and mouth, a glob of pre-cum smearing across them. Jeff's eyes were half lidded as he opened his mouth again for his Dad's meaty cock, Mike couldn't help but love how submissive Jeff looked. Mike guided the tip of his cock into Jeff's drooling mouth, Jeff's tongue immediately began to lick and lap over the pre covered member, savoring the raw, musky taste. As Jeff closed his eyes and began to take more and more of Mike's cock into his mouth, his ears reshaped into little points and began to grow outward and upwards, golden fur spreading across them until they were fully feline.
Golden fur began to spread across Jeff's neck and face as he moaned and took half of Mike's glorious cock into his mouth, suckling and swallowing the tip down the back of his throat. Jeff had never sucked a cock before in his life, but the musk driven lust was making him into a natural. Mike growled in deep pleasure, his eyes glowing with a fiery lust as he continued to hold Jeff's head by his hair. Mike slowly yet roughly began to thrust in and out of Jeff's mouth, it beginning to reshape and reform into a maw. The golden fur continued to grow over Jeff's body, covering him fully with a soft silky pelt, but unlike Mike, Jeff began to lose muscle mass. Almost all at once, what little muscle Jeff had shrank away, leaving a tight, lean body of a twink. Jeff's cloths were loose, his pants and underwear slowly began to slide off him from both being too loose and from the tail forming behind him. Jeff moaned louder, his voice becoming higher as Mike began to become more aggressive with his thrust, causing Jeff to nearly deep throat his father. Jeff's body began to shrink, becoming shorter and smaller, Jeff wasn't just becoming effeminate, he was becoming younger. Jeff continued to become younger and smaller until he looked to be thirteen, his the rest of his clothing falling away from his small frame. As Jeff had been growing younger, his cock had began to shrink, growing smaller and smaller until it was barely an inch and a half long hard.
Mike slammed his mighty cock one last time into Jeff's little maw and his thick, sticky seed released into his little cub. Jeff began to slurp and gulp down as much as he could of his Daddy's thick, warm cum, but the force was too much and it began to spill out over his chin. Mike quickly pulled his cock out of Jeff's mouth and finished his load onto Jeff's tiny face and chest. At that moment of getting covered in Mike's come, Jeff's mind fully changed. The chronivac had read Mike to be Jeff's father and since Mike had changed it changed Jeff as well. Jeff panted and looked up at Mike with groggy eyes before passing out. Mike chuckled and picked up Jeff and began to head up stairs. "You pleased your daddy well my little cub." Mike said as he turned down the hallway and towards Jeff's room. Mike grabbed the doorknob, but found the room to be locked, but with Mike's new muscles and manly power he was able to bust open the door without disturbing the tiny, sleeping Jeff in his arms. Mike placed Jeff on his bed, still covered in cum, before turning to leave. But before Mike could leave the Chronivac had caught his eye, Mike walked over and sat down, reading the Chronivac's screen and began to discover what happened and looked at the options with a mischievous and horny purr.
