"Cool! A performing Bear." Jeff thought as the photo was revealed. Jeff's heart jumped for joy! It was like a dream come true, how did the doctor know? It certainly wasn't on his application that he fantasized about this. So that was what was meant about 'willing'. Well Jeff was certainly willing, now, he'd always thought of himself as a bear and his physique showed his ursine love of food, relaxation and pleasure. Even in high school, he'd been the big linebacker with extra pounds and after he'd been the ex-jock gone to seed. If he was going to change into an animal, a black bear was one he'd be happy with.
The life of Hollywood bear was a fairly easy life and with a human mind he would make tons of money for any 'trainer' as he would come 'pre-trained' with his intelligence. All he had to do was follow direction, pretend to growl, paw at things, etc. all on cue. Further, he'd be very safe. Jeff wouldn't harm a fly, let alone maul his 'trainer'.
He imagined that the sexual part could mean placement in porno video production or it could mean breeding smart bears. He would have to wait and see, but if this was what was planned, he'd tell the doc that he was quite happy with the choice and would willingly take whatever treatments needed to change him into a bear.
Jeff felt his muscles bulge, he was on his way to becoming brawny, his fingers, palms, toes and bottoms of his feet felt funny as the places were pads would form tingled. He saw the nails blacken and begin to push out as claws. He felt his beard growing on his cheeks and chin, it itched like Hell and at the same time he watched as his skin blackened with the coming of subcutaneous black hair follicles that would be his luxurious black pelt. Jeff got an erection thinking about all that bear fur.
The nurse say conspiratorally to you, "I think that guard has angered the doctor. He'll probably end up being a bear like you... though I think a larger breed is on the slate for Yellowstone. The guard is single, quite muscular and very unwilling to be changed... he'd be the perfect candidate."
The nurse leaves the room and you nod off as the injections are making you sleepy.
