We invite Prestige exclusive actress Mion Sonoda to experience pleasure she's never experienced before! This time, the experiment we're conducting is a full course designed to make her climax over and over again. We try out "Tantric Yoga," said to be the world's most orgasmic technique, on her body. We go through all the processes, from "meditation" that connects our mutual consciousness, to stimulating the "chakras" scattered throughout the body, and stimulating her "G-spot," and finally, when we reach penetration, a clear change appears in her. Her cheeks flush, her bare skin begins to sweat slightly, and her convulsions gradually grow stronger, bringing her to multiple orgasms with just a few thrusts... She also experiences numerous convulsions and orgasms in four other experiments, including "extreme teasing" and "inhaling lustful herbs," and rises into a trance-like state!
