You found my lamp by pure coincidence, or so you think. In reality, I chose you as my new Master. I could sense that you had wishes to make that couldn't come true without my help.
I waited patiently for you as you carried my lamp home with you. And you called out for your roommate to make sure you had the place to yourself. I could sense your heart racing even before you finally placed your hand back onto the tarnished metal of my home. Then, finally, you ran your hand across the seal and unleashed me.
The smoke escaped first. You seemed so scared, yet so excited. I knew just the form to take. So when the smoke finally cleared, you found me laying on the floor in my curvaceous glory, oil from the lamp coating my newly changed body.
"Thank you for releasing me, Master." I smiled. "What shall we do first?"
Option 1 - We have some fun before the real magic starts (Sex scene)
Option 2 - You make a wish (Best comment wins)
Option 3 - We get interrupted by your rude roommate barging in and taking over as my new Master (Submissive option).
"Well, Master, what will it be?"
