There's a girl at school in the grade below me named Dori. She's actually kind of pretty, but she always acts strangely around me. Anyhow, apparently this girl goes through underwear real fast. She ruins them somehow. And how would I know? Well, yesterday Dori's sister was in MY sister's room whining about Dori. She went on and on about how she won't let her little sister borrow her panties on anymore because she leaks on them these days. Or something like that. It was hard to hear through the door. Once I heard that, something that had happened the first week of school suddenly made sense. Dori and her sister got into an argument in the hall near my locker. I remember trying the combo on my lock for like the fifth time when her sister started whisper-shouting something about...panties? When I turned, Dori was shaking her head at her sister but looking right at me! Her eyes were teary. All at once, her sister dropped her books, reached under Dori's skirt and angrily jerked her panties down! Dori opened her mouth, but she didn't scream or reach for them or anything. She just looked down at her panties while her sister tried to pull them off her feet. They took a while to disentangle without Dori's cooperation, but they finally came free. Her sister stood up, shoved them in Dori's face, "See?" and stuffed them into her purse. Dori looked back over at me, so I turned back to try my combo one last time. After lunch, I "followed" Dori up the main stairs. (My class is on the 2nd floor.) She was holding the back of her skirt down with her free hand. At one point she tripped on a step and reached for the railing, and I got a flash for a split second, but all I really saw was a dark patch of hair. Even so, my balls got sore during Math.
