Meanwhile, outside, Seaborne was leading the dog by the collar to the truck.
After opening the back of the truck he bent down to pick up the dogs front legs to place it inside, but it was already too late when he noticed the dog had already gained some mobility with his fingers and pulled off Seaborne's mask.
A very husky voice spoke, "There, lets have some fun." and the dog jumped into the truck.
Seaborne was just about to run when the scent of the dog made it into his system. He lifted himself into the truck and closed the doors as a bulge began to form in his pants.
The golden retriever Chase was now seated on his forming ass along the back as his body continued to change. Bulkier legs were spread apart with his shortened tail wagging slightly between them. Seaborne drooled as he saw the changing dog boys penis sticking out hard as a rock. With muzzle pulling in slightly and eyes turning a deep blue he spoke to the man "Take those clothes off and get over here and suck!"
Seaborne's lust filled mind didn't think twice as he began to strip off his clothes, his 30 year old body being brought into the open with only his dog tags on.
Seaborne moved in on the now half dog Chase & half Bryan boy, bending over and kissing him on his partially extended face and long tongue infecting himself.
Seaborne's hair was lightening to a dark blond as it thickened across his body as the two began to 69, each taking the others cock's into their mouths. Chase's dick had a thick base with thin red skin moving down to the almost human looking head, Seaborne's face was in a forest of fur as he madly sucked. The sexual activity quickened Seaborne's change into 50% chase, which would mean 1/2 himself mixed with 1/4 dog and 1/4 Bryan. Years were melting away as body hair thickened across his body, a short tail pushed out above his ass. His ears gained only a slight point to them as his face pushed out only a bit. The now 23 year old began to spasm along with Chase as his changes began to complete, shooting their loads into the others mouth.
