I decided to go home. I had some ideas but I really needed to be in a more familiar environment to have the courage to speak out the words.
When I walked through the door I almost fell over my sister.
"Hey, Jon, you jerk, watch where you're going!"
Zoe, 2 years my junior, was sitting on the hallway floor trying to tie her long, high-heeled boots. She was clothed in a long, black dress, and her face was made up pale, with contrasting details. She was my opposite: sponatanous, independent and confident. I, on the other hand, were more of a thinker, preferring to plan out in advance, and I didn't have the great confidence my sister seemed to have. Though, despite our different nature, or maybe because of it, we had a good relationship.
"Sorry, I was completely in my own thoughts," I answered. "Do you need help with those shoes?"
"Would you? Thanks."
I helped my sister, and as she left, I walked up to my room. God, I was horny. I walked into the bathroom I shared with Zoe, locked the door and started fantasising. As my cock grew harder, and my mind hornier, I had an idea. I had a fantasy, a sick and twisted one, which I would never be able to live out. However, with the ring, everything was possible. On the other hand, I probably didn't want to live out the fantasy for the rest of my life. And what if something went wrong? I stopped my masturbation, and sat down on the toilet, thinking. I would have to design a series of wishes to prevent anything from going wrong. If I only could keep myself from wishing my fantasy for long enough...
I twiddled with the ring on my finger, still thinking about the safety catches. I would have to wish that when my fantasy was fulfilled, I would return to my own, original self, the way I were here and now, with the ring still in my possession. That would probably solve most problems. I'd just have to set a time limit, or some other way of fullfilment, to my wish.
But all of that seemed so... technical. My cock was now rock hard in anticipation to what I was about to do. "I wish...I wish..."
