"O, oh my god... How can such a perfect dildo exist?" One day, Yrilia goes on a blind date with her nemesis, Michaela, at the request of a close friend. Frustrated by his inability to hold a proper conversation, she curses him in her heart. At that very moment, a 'sex toy' of impossibly perfect shape drops from the sky...? "This is mine forever." Using the 'toy' day and night, Yrilia eventually realizes that it is actually someone's physical body—but by then, she is already addicted to the unbearable pleasure. "Did you enjoy using this damned curse?" Just as she is succumbing to temptation and having a wonderful time, Michaela, her lifelong rival and sworn enemy, appears before her... "Revenge, you say? That doesn't sound bad at all."
