"I hate math. It's so not fun. But I had to pass my stupid algebra test. Luckily there's this really smart guy in my class who offered to help me out. I didn't think he was that cute at first. He's kind of nerdy, and when he came over all he talked about was quadratic equations and variables. It made my head spin, but I think it turned me on that he was so smart. Either that, or I was just horny. I got tired of hearing about math. I wanted to fuck.
