Sister to Bitch

"Strip naked," Peter instructs Melanie.

Melanie obeys, and Peter takes in her naked form.

"You always were a bitch to me," he said. "Now become my bitch. When I snap my fingers, you will become my pet dog, until I say otherwise, but I most likely won't...oh, but you'll still use the bathroom like a human though. Don't feel like picking up shit or piss."

With that, I snapped my fingers, and Melanie got on all fours.

"Woof! Woof! Arf!" Melanie barked.

"Aw, who's a good bitch?" Peter laughed as he stroked his sister's belly and came in Selena's mouth.
