Your sister comes back from work

It didn't take long for my sister to get back from work. Sam worked as a barista at some coffee shop. She was fairly good looking with brown hair and B cup tits. Nice arse and she wasn't fat. I wanted to test out the wishes while some one was also in the room.

Sam was wearing casual clothes (yellow tshirt,blue jeans and blue sneakers) because the coffee shop was a semi hipster place with no uniform. I thought "I wish Sam was wearing a blue tshirt and not the yellow one". Again the magic just changed her tshirt with out any notification. Sam didn't seem to notice.

"Hey Sam. That's a nice blue Tshirt, is it new?" I asked her. "What this? Yeah I bought it last week." she said. Hmmm. Interesting. I thought about my wish. Perhaps saying "was" made it retroactive? I needed another test.

"I wish Sam's shoes will transform into sexy red strappy high heels." you think. Immediately they changed. Sam almost lost balance and grabbed the arm of one of the new arm chairs. "What the hell! My shoes!" she yelled as she looked down. Gone where the boring generic brand blue sneakers and in their place where the new sexy red heels I was imagining. "Wow!" was all I could say. "I didn't know they let you wear them to work! They look good on you." I told her. "Huh! These aren't mine. I was wearing blue sneakers just a moment ago!" she said in awe.

This was interesting. If I phrased the wish right it would either change the past it seemed or would just have an immediate effect. I'd need to be careful how I worded them and my thoughts also seemed to guide the changes as the heels looked like what I was thinking of when I made the mental wish. It kind of made sense though as the genie did say if I thought "I wish" then it would happen.

"I wish Sam's jeans and tshirt will transform into a sexy red and white silk mini dress maid uniform with a small red cap fastened on her head." I thought. Suddenly Sam's old jeans and tshirt where replaced with a hot red and white maid uniform.

Sam looked down at her self in utter confusion. "What. Why am i wearing this?" she said in total confusion. "Isn't that what you usually wear to work?" you tell her. "I wish Sam usually wears sexy maid uniforms with high heels to work and has a large collection of different kinds of both in her room." I thought. Sam's confusion disappeared immediately as if she was never confused.

"I wish Sam would act like my maid when she's at home and she gets aroused doing things for me." I thought. Sam went to the kitchen and brought me a coke and placed it carefully on the coffee table next to the sofa.

So far so good. "Do you need anything else, Sir?" she asked. "No thank you Sam. You may start cleaning the house now." you tell her. You watch as she smiles and a slight quiver in her smile indicates a mini orgasm. Sam turns around and goes back into the kitchen to start her duties.

This was a fair bit to take in and you really did want to do some more testing. After all testing revealed the retroactive changes that seem to have been made from your past tense wording. Also you now know that another wish can either change or alter a previous one.
