The neighbor's dog continued to clean Fang's rear while he slept. Asleep, Jeff didn't notice the neighbor's dog getting excited.
Suddenly Jeff felt something press painfully into his mouth. The neighbor's dog's cock stabbed through his lips into Fang's intestines. Fang jerked awake and tried to run, but the dog had looped his paws over Fang's hips. Fang was forced to submit while the big dog pumped his cock into Jeff's mouth.
Jeff, back where he was the day before, silently whimpered as he was distorted to the knot forming inside him.
The neighbor's dog continued his playing, and bit Fang in the back of the neck. Fang yelped, and squeezed his hind legs together, pressing Jeff even tighter around the neighbor's dog's cock.
The neighbor's dog climaxed in Jeff, spraying dog cum all through Fang's intestines. Jeff screamed.
Jeff suddenly heard a loud beep in his mind, as the Chronivac finally located him. A screen popped up in his vision, showing his newest form.
