I'm not used to having more than one fantasy...also fantasizing about my celebrity couple, and they intertwine sometimes, I'll be thinking about one and then the other.
I like to fantasize about conversations in class. It's hard not to blush when he smiles at me. Gah, why is it always the teacher? I had a big crush on my teacher when I was 12, and I had a crush on another teacher a few years ago. At least it's a common fantasy???
