A Gift for Brother #6 (Iry-Ice)

A story blends mundane reality with a girl's intense, erotic masochistic fantasy on the day of her older brother's college entrance exams. She bids him farewell while spiraling into a vivid public execution delusion, imagining being stripped naked and humiliated before a crowd as her brother pierces her to death with a thick rod. The fantasy climaxes with her screaming in agonized ecstasy before the sequence abruptly shifts back to reality, where she offers well-wishes for his exams.
