Well since tonight is that big Halloween party with the 1,000 dollar prize for best costume I was thinking we could use this to make it so we can win that prize.
Jeff looked at Emma as she sat down at the computer "that sounds like a great idea we could go as a knight and slave girl with costumes that are real and not made out of tin." Jeff started to pace around the room as he was talking "well what do you think of that idea."
As Jeff was talking Emma was typing away "well I had another idea" as she hit enter.
Jeff felt his body start to tingle and ran to the bathroom "what are you doing."
Jeff got to the mirror in time to see the changes as they were coming to an end. What he seen was a gorgeous 18 year old girl that was bald except for a large patch of blond hair trailing down her back. Jeff looked down to see that she was now dressed in a pair of transparent harem pants and a pair of gold pasties that covered her areoias. As she continued to look her breasts began to grew until they were a DDD-cup, then a collar with a chain handing between her breasts formed.
Jeff let out a gasp as she turned and went back into the bedroom "What the hell did you do to me mistress" she said "Wait why did I call you mistress."
"Well" said Emma "A slave should always address her owner that way."
Jeff looked up to see that Emma was now dressed as a noble woman out of the Arabian Nights "what is this mistress."
Emma walked up to Jeff and grabbed her tit as she squeezed "well I made a few changes to your knight and slave idea."
As Emma squeezed her tit Jeff wanted to tell her to stop but what came out was "M-M-Mistress please i-if y you ke- keep doing th-that I am go-going to wet my self."
Emma took her hand away from Jeff's tit "Maybe your right we don't want to mess up your outfit Jasmine. Oh by the way you are going to find that you can not break character, you will be an obedient slave until I change you back so lets get to that party" as Emma slapped Jasmine on the ass.
Jeff found herself smiling as she said "yes mistress" then started to walk out of the room.
