As Ty stands over the sleeping Mark, hate swells within him. Ty thinks of all the times he has been beaten or ignored or jeered at. Obviously the bastard has to keep going to work and making money for the family, so I can't change him too badly. Mark the construction worker needs to be taken down a notch. June is now a poodle; lets make Mark one as well.
Ty smiles as a thin, lengthy tail sprouts from Mark's tail bone. Then he laughs when the same floppy ears as June has are hanging from his step-father's head. At Mark's wrists and ankles, little bands of tightly curled gray fur appear, though Mark's will not require grooming. He can work with those changes. Everyone will find him strange, but just strange enough to make fun of, not study in some lab.
Each night when Mark enters the house, he will change completely into a poodle. He will be more concerned with fucking his wife than messing with his kids, and she will let him have her when she is not doing something that she was told to do by Ty. With the wish completed, Mark disappeared. Beside his freakish poodle-woman wife lay a male poodle that would answer to the name of Mark - and if he could talk would be madder and more confused than anyone...ever.
"Oh, Mark, you may return to your human form in just enough time each morning to get cleaned up and ready for work and to make it there on time." Ty wondered if he had forgotten anything. He had to make sure his use of the power didn't bite him in the ass. Satisfied with the way he had dealt with his family, Ty went to bed thinking about what he could do next with his new found ability.
