“OH NO!” Doc McArt exclaims as he starts to unload in your mouth.
He grunts as his cock spews about a quart or so of thick warm sperm. You suck down as
much as you can but some dribbles in your beard.
“I’m sorry. I’ve spilt the new Ursus Major formula we’ve been working on all over us. It’s
designed to be a topical solution, so you have become an accidental test subject for the
formula. I have been testing on myself and you can see the changes it has had on my
body. I believe you noticed my tail and changed genitals while you were pleasuring me.”
McArt explains while looking at you with a concerned face.
“You mean I’m going to become more bear like,” You ask as your cock strains painfully
against your pants.
“You will most likely grow a tail and more fur. Your penis may taper like mine has; your
testicles and prostate may grow and produced much more semen than now. I’m not sure
how it will interact with the Ursus Magna formula we were testing on you. This formula
was used genes from Ursus horribilus and the one injected in your scalp was based on
Ursus americanus. The formula works on the genetic level and I’m afraid that even if we
went and washed it off it would make little difference. ” He continues looking at you with
lust in his eyes. “You need to get out of those clothes so they don’t restrict the growth
you may go through. ”
Images of you as a bear fill your head as the Doc describes your fate. You see him down
on all fours and you, a full bear, bent over his backside. You imagine what it would feel
like to have your ample hairy belly draping over his back, your long cock sliding into his
anus and your grapefruit sized balls slapping against his smaller human nuts.
The Doc reaches down and pulls your shirt over head and off while licking his lips in
desire. Next he helps you to your feet and you are drawn into a deep kiss. His tongue
snakes into your mouth reaching almost to the back of your throat.
You begin to notice that….
