The Substitution Stone: Plus Mom, Minus Zoe?

Just like before, Jon's wish wasn't granted the way he wanted to be. Instead, his wish was changed to "I wish *Mom* was here doing this instead and that you would just leave." Suddenly, his mother appeared in the middle of his room. She was completely naked and had a look of pure lust in her eyes. She just needed to make love to her son. She was so desperate for him. Then, at the same time, Zoe turned around and walked out of his bedroom. "No! Why isn't this thing working?!" Jon yelled, as his mother wasted no time at all at showing her undying love and lust for him.
