This story is a continuation of another story of mine “Pet Therapyâ€. Alternatively, it can be read as a standalone piece. Paul, already has agreed to become a permanent slave dog for his Mistress, Christine. However, his acceptance doesn’t mean he is still ready. Christine wishes to initiate him into servitude and to brand him with her own mark. The story describes all the preparations and events before and during the so called “Initiation†procedure. As a gift for his dedication, Christine purchases a surprising present for Paul. She brings a full scale obstacle course with tunnel, jumping bar, weave pols, and a seesaw. The plot continues with the surprising announcement from Christine. She had to travel alone and leaves Paul with his ex-girlfriend Laura. Remembering their nasty breakout, Paul is terrified to hear the news. As expected, Laura furious with Paul, walks him through a vast variety of humiliating tasks. When Christine finally arrives back, Paul just can’t believe that the torment is over. The story ends with the description of a new game invented by Christine. In a “Driving Ball†adventure, Paul is required to move the ball through the entire obstacle course. Exhausted and completely worn out, Paul finishes his duty. However, his Owner already prepared a new challenge for him. Remembering their agreement, she notifies Paul about her decision to neuter him. Will Paul keep his most valuable body parts intact, or lose them forever?
