As Jen finished speeking, Jason felt a strange tingling all throughout his body. He looked at his arm and saw tiny little hairs start to poke through his skin at a rapid pace. It didnt hurt, but it just felt strange. As the fur started growing, Jason also noticed his muscles starting to grow. Always having been a fan of wokring out, this made Jason even hornier than he already was. Next, jason feet began to elongate, his ass grew much larger as his anus became larger and puckered. All the while, Jen was standing next to Jason jackingoff his new fox cock. As Jason was standing up on his newly hoofed feet, A long shiny horse tail grew from above his ass. He was now horse from the waist down, and furry human from the waist up. Next, Jason felt his face begin to elongate as his ears became pointed and moved the the top o fhis head, he was becoming as horny as ever. Last, but definitly not least, Jason cock began to change. It started to leak copious amount of pre-cum, and then started to grow. The modest, hard, pink, 6-inch, human cock grew in length and width. ALong with his cock, his balls grew to the size of grapefuits and were contained in a furry black sac. His cokc kept growing until it was past two feet. It aslo became mottled black and pink, and the head flared out in the shape of a mushroom. Jasons cock stopped growing right in front of his new muzzle. He gave it a lick and whinnied in pleasure.
Thats when Jen...
