Justin can feel his body go through the changes as he is pleasuring and getting pleasured. His butt begins to itch as a thick fur begins to form along with the nub of a tail. Then the fur begins to slowly envelope his whole body from it origination. Suddenly, as you cum in Justin's mouth, his whole body tensed up and began forming huge, bulky muscles all over his newer anthro bear form. As Justin still had your cock in his mouth, he watched as his face elongated into a muzzle, with his nose growing cold, moist and black, along with his teeth elongating into sharp fangs and his tongue growing to a length that would fit his new muzzle. Justin still continued to suck and swallow every last drop of cum and as he did so, his feet and hands turned into thick, puffy paws with thick, long and black claws. As you finish unloading in him, Justin looked down and noticed that his cock grew to a hard thirteen inches, as thick as a beer can and a half and still human in shape.
As Justin pulled off your cock, he stood up on his hind legs as a new anthro grizzly bear and stood there in awe...
"WOW what the hell just happened here???"
"Well my young intern, you just happened to walk in a couple of bears in lust!"
"Well yeah I saw that, but I went from being straight and human into being a gay anthro grizzly bear!"
"Well... how do you like it?" You asked
"I love it, I feel so strong, powerful and super horny! I could never get this horny with my ex-girlfriend. Ex meaning im dumping her right now for one of you guys!"
"Splendid... how would you like to help the two of us make all the guys on campus like us...?"
"I'd love it, I dont know why, but I have this strong desire to spread our gift to the other guys. The thing is, I want to turn the head quarterback of the football team. He is the most muscular out of all the guys on campus and he already has a big dick, and believe me, ive seen it while in the shower room together. I can't wait to see how he turns out!"
"Sure lil' guy, he's all yours!"
