—What do you want? — said Cathy as Christopher entered her room, she had gone to her room after Chris got his package.
—Oh well... you see, I think this package wasn't for me..
—What are you talking about?
—I think it was for a beauty or a sexy girl, I dunno...
Cathy rose from the bed whit an interest expression
—Maybe a model... yes, a beautiful model I think
—What was inside that package Chris?
—Oh?, no nothing, I just wanted to ask you if there's a way to send it back, after all there's no one on this house that wants to use something like this... no there's no one who COULD use something like this...
—Enough! —Cathy slammed the door and then locked it, she wasn't gonna let Christopher get away without knowing what was inside that package; she snatched it from her older brother and opened, revealing the bunny outfit.
—See? I told you, you can't use it, it wouldn't fit on you.... not that you want to use it though. —With those words Cathy face turned red as her expression changed from disappointment to anger.
—Of course the costume would fit me!
—Yeah, of course —said Christopher with a monotone voice as he collected the accessories that Cathy threw to the ground when she snatched the package; Chris smiled and prepared the camera in his pocket.
—Gimme that! —then she removed her pants and shirt and put on the corset, —Seee?......
—I got you!!!! —Yelled Christopher as he started to take photos of her sister; but Cathy's body went limp, and her gaze was lost, she didn't react at all.
—Cathy? are you ok?
—...yes —she answered with a monotone voice
>>I wonder if it really worked... well, there's only a way to find out<< Christopher thought
—Cathy... I want you to walk on all fours while you bark as a dog — Instinctively he crouched waiting for her sister punch, but instead he heard something incredible.
—Bark!, bark! —She was acting as a dog
—It works!, it really works... Ok, stop, it seems like the effect isn't permanent until I put on the bunny ears... I assume that applies also for the entire costume, so... —he threw to her all other pieces of the suit except for the bunny ears. —Dress up slave!
Cathy started to undress her, regardless of his brother watching her she removed even her underwear and then put her all the costume, then as the final touch Christopher put into her head the bunny ears
—Good, Listen Cathy, you're mine forever, from now on you will address me as master or owner, but only when we are alone or in presence of other slaves, you will do whatever I tell you to do, you will worship me, also you will remember the fact that I tricked you to wear the costume but that will not make you anger, in fact it makes you happy and you will wish to share that happiness with all other women even our mother and sister, got it?
—Yes master.
—Good
