When she regains full consciousness, she panics at the bizarre surroundings—only to discover a collar and leash fastened around her neck. The man slaps her to calm her down, then silences her cries by stuffing his cock into her mouth, beginning her training as a pet. He records and livestreams the entire process. Soon, Ai's virginity is taken. Subjected to relentless, cruel training every day, the inexperienced girl gradually begins to feel sexual pleasure, eventually craving his cock on her own. Spanking, slapping, deep throat, squirting, multiple orgasms, fainting, and even reverse domination—this 140-minute film unfolds a detailed story of Ai Nonose's awakening and submission through endless pleasure.
