...the blue collar with the boxing glove on it. Sgt Randy took it from her and placed it round her neck. He removed her dog collar and sat back in the seat. The collar glowed with a strange blue light and a small sound was emitted.
Amy's black fur muzzle began to change. Her canines shrank and the fur lightened to an earthy brown. Her ears began to change too, turning brown and lengthening. Her bushy tail stopped wagging and lengthened. She jumped from the back seat of the car as her long tail swipped round, nearly hitting me in the face.
She landed on two long brown feet. It was only then that I worked out that she was becoming a kangaroo. Her feet legthened giving her stability.

"D'ya like that?" He asked him. He nodded his head fast, flecks of cum flying in the air as he did so.
Randy turned back to me. "Still sure you don't wanna swap it?" He asked.
