RPGM Magical Girl - Magical Girl Breasty

Chigusa Ayase gets chosen to be a magical girl, except her power source is exposure. To fight she has to flash and humiliate herself in public, on sleazy TV variety shows, through behind-the-scenes accounts, and the boys in her class quickly turn her into a shared toy. She starts out making excuses to avoid losing, then the attention rewires her, and chastity stops meaning what it used to. A morally corrupted school-life exposure-shame SRPG that ends exactly where the title warns it will.
