A man lives with a beautiful doll named Emiri, calling her his "girlfriend" and spending all his time exclusively with her. One day, he discovers a special feature built into Emiri—the "voice function," which allows her to respond as if she were human when given specific dialogue input. Upon learning of this function, the man begins to train and dominate Emiri. Through deep throat sessions and toy play, Emiri reacts passionately, as if she were alive, eventually begging on her own, "Give me your cock." Her transformation further fuels the man's desires, driving their relationship into new, intense territory.
