Naoko

Naoko is a 4th generation onahole purchased by the main character, Tarou Ishijima. During her personality upload, an error occurs, giving her a more flirty and teasing personality, while also making her hornier and more needy for sex than is usual for an onahole. As a 4th generation onahole, she is able to manipulate the temperature of her mouth, and automatically adjusts the shape of her mouth to perfectly compliment the cock of her master. She refers to Tarou as her master, and often mentions her love for him, expressing that she is his to use however he pleases. She often shows reverence towards earlier generation onaholes for being able to satisfy men despite lacking the enhanced features of the 4th generation.
