Beautiful new female baristas working at a coffee shop undergo hypnosis customer service training, gradually falling under mental control. Yui quickly succumbs to hypnotic induction, sinking into a deep trance state, while Rino initially resists the control but is eventually dominated by subconscious suggestions, slowly drawn into the hypnotic world. As both experience the pleasure of hypnosis, their awareness becomes distorted, losing sense of time and surroundings. They are trained to overcome embarrassment in public, freezing in contorted facial expressions and unnatural poses, exposing their pitiful states. To increase endurance during work, they undergo hypnosis that turns fainting into euphoria—struggling to resist, they're forcibly pushed into unconsciousness by overwhelming pleasure. Various customer service simulations are conducted, including masturbation triggered by taking orders, mirroring exercises to strengthen teamwork, and responding to muddy lesbian scenarios, driving both women's minds to the brink of collapse.
