A female otaku who attends a girls' high school lives an isolated life with no contact with men—until one day, a strange man approaches her at the park. Bonding over an anime keychain, their conversation quickly shifts to shared interests in anime, sparking an intense connection. Excited yet nervous from her first interaction with the opposite sex, she follows along, overwhelmed by rising emotions. With little sexual knowledge, she remains unaware of what's happening—until the man thrusts his penis into her most sensitive spot, exposing her vulnerable body. Under the influence of an aphrodisiac, her entire body transforms into a hypersensitive pussy, driving her to beg for her first real-life cock. This is the story of a pure otaku girl's awakening desire.
