After returning from vacation, Billie and Debbie started playing around with the Lucy App on their phones again and wanted to make some of their crazier kinks a reality. Billie had always liked the idea of Pet Play and asked Debbie if she would be her Mistress/owner. Debbie loved the idea and agreed immediately to help make Billie&#8217;s dreams come true. Little did she know that one of Debbie&#8217;s biggest fantasies was to be a dominating mistress. So she was quite surprised when she found herself on her elbows and knees on the hard wood floor of their living room made to act like Debbie&#8217;s obedient pet. However, both Debbie and Billie enjoyed the experience a lot.<br /><br />Well, it has been three weeks since they decided to explore these new roles in life and not much has changed since. Debbie has fully committed to being Billie&#8217;s owner and mistress and Billie has become the most loyal pet an owner could ask for. Billie was a bit alarmed however when Debbie decided to modify her body to look more like a real pet. She used the Lucy App to change Billie&#8217;s arms and legs into thicker, stubbier appendages more fit for walking on all fours, and she also modified Billies face by stretching it into a muzzle of sorts. Needless to say, Billie had been turned into a perfect human pet, and she came to accept the changes as a gift from her owner. Billie loved being Debbie&#8217;s pet so much that she told her owner that she wished she could stay like this forever. Little did she know that the Lucy App heard her wish and made it come true. Hehe, Billie is in for a big surprise if she ever decides she wants to be normal again.
