Jon thought about it for a while. One factor that would always keep him paranoid was stone itself. As it was currently, anyone could grab it. His sister, his little brother, mom, dad, anyone else... It was hard to protect it and still have access to it. He could wish that it would change it's form and have it always on his person, but again - someone could steal and take it. He couldn't be vigilant 24/7. Even with his new powers.
For that reason he had to figure out a way so the stone could only be useful to him and no-one else could use it. And he thought he had an idea. "I wish that only I and those I allow to could use the wishing stone. I wish that I didn't need to physically touch the stone to make wishes while I am in it's range of influence. I wish that the stone would only grant the wishes when I meant to use it." the stone glowed brightly and Jon decided to test if the wishes worked. He put it on bed and without touching it made a wish "I wish I had can of cola." he said and stone glowed, can of cola appearing in his hand. He smirked, satisfied. Phase one was complete. Now for really serious thing that he thought over long and hard when he actually got stone for first time.
The annoying factor about the stone was that it could interpret wishes in very random ways, unless a lot of details were provided during wish. But that was also hard, because when you need to take in a breath stone will cut off wish and so you were forced to do multiple small wishes instead of long complex ones. So Jon thought that it would be better if he added additional factor to wish granting thing - make stone know what he desired and make it so stone would only grant wishes in way he desired. For that he decided to turn stone into... a girl.
By doing that he would add additional human factor to stone. Stone would be walking, thinking, breathing. He could make it so stone would want to grant his desires and only his desires, making it safe from everyone. He could even make it that when he let others use the stone if they made wishes that would hurt him or those he sees as important to him, stone could refuse to fulfill the wish. It seemed foolproof to him, though he knew that nothing truly was. Still, it was better than anything else he could come up with.
With those thoughts Jon started his wish "I wish that wishing stone would turn into beautiful woman that would love me, would be completely loyal to me, would have all powers of wishing stone and would use them to only grant my wishes and desires." he said his wish and he had to close his eyes and look away as stone started to glow brightly, changing it's form.
When Jon was able to look back at stone he instead saw as stunning woman. She had long black hair and beautiful face with full pink lips and blue eyes. Her body was an epitome of perfection with large E-cup breasts, narrow waist and wide hips. She also had seductive long legs and delicate, graceful arms. She was currently wearing a golden and red harem outfit. She actually was just like Jon imagined she would look like, right down to tiny details.
"Hello, master." the woman said in her sexy voice, though her expression remained blank. Jon smiled "Hello. Do you have a name I could call you with?" The woman shook her head "I don't, master." Jon continued smiling "Well, let's fix it. I wish that from now on while you are human your name would be Grace." Grace's eyes glowed, granting him the wish. "Thank you for my name, master." Jon frowned a bit "Guess you don't know how to act as human... Let's fix that too. I wish that you knew how to act as human female and would have all knowledge and skills required to live in today's society and would also feel and speak like human." Grace's eyes shined again and she could smile now "Thank you, Jon. Unless you still want me to call you master?" He shook his head "No, you can call me Jon. You aren't my slave, I would like to think of you as my companion and friend. Oh, we should probably fix your clothes? I wish that Grace could change her body and clothing in any way she desired without any limitations." Grace's eyes glowed again and she looked down to herself, shifting from her harem dress to bra and panties, then forming jeans, sneakers and T-shirt on her body. "Well, I do look good. Thanks, Jon."
He smiled "You are welcome. Now, did you change anything in my initial wish to make so you could live in this house with me, Grace?"
Grace nodded "Yeah, I did. I am your..."
