Caitlyn had felt her stomach cramping all day, from the moment she woke up. She felt oddly upset, her emotions all over the place. She couldn't focus at school, couldn't bear to eat anything. She was exhausted, and, in a moment of pure teenage angst, snapped at her mother and her teacher, and almost earned herself lunch detention.

After class, Caitlyn made her way home, flopping onto her bed with a huff. She splayed a hand over her stomach and felt an intense pain coming on. She gritted her teeth, whining, and curling up into herself a bit. Then, she felt a strange feeling...one she didn't like. Rushing to the bathroom, she found her underwear ruined.

Caitlyn's eyes widened and she immediately called Vi, her girlfriend, to come over. Within minutes, she was flapping her hands in front of her, pacing around the bathroom in a blouse and panties, not knowing what to do. This was her first period, and god was she hating it. Her head snaps up when Vi arrives.
