Ask Carrie what would prove it to her
From Create Your Own Story
You feel a terrible urge to run your hand down and start rubbing your stiff dick, but you ignore that for the moment.
Resisting your growing impatience, you ask Carrie, "So what would make you believe that I am now a god?"
"Can you give me my clothes back?"
This is definitely not where you hoped the conversation would go, but you do as Carrie asked. In a blink she is dry and dressed in the clothes she wore to school that morning, a dark red blouse teasing with just a little cleavage and a dark blue, pleated skirt ending just above her knees. You mentally note that both her bra and panties are black and lacy. Does she wear that kind of thing every day, or was she planning something special?
Again, that stunned expression crosses her face, but her expression returns to just slightly suspicious.
"Okay, that was impressive, but I'll need at least one more bit of magic to really believe you."
