A special experiment is finally held from Prestige, featuring Yuina Ema. A full-course pleasure test is specially designed to make her experience ecstasy like never before. The first stage begins with meticulous licking of her sensitive nipples and genital area, teasing her with tantalizing stimulation. Then, a new actress appears, provocatively displaying her own pursuit of pleasure, further intensifying Yuina Ema's frustration. Her expression fills with anger and anxiety, her body trembling as emotions surge. To deepen this state, a long-desired penis is inserted, triggering full-body convulsions as she is driven to repeated climaxes. Through this four-stage experiment, she gradually enters a trance state, guided toward a new realm of pleasure.
