A special experiment was conducted for Sonoda Mion to experience pleasure she had never known before. To maximize her satisfaction, the world's most intense orgasm technique—tantric yoga—was introduced. Through meditation-induced consciousness fusion, chakra stimulation, and G-spot targeting, every step led to penetration, after which clear changes appeared in her body. Her cheeks flushed, her bare skin glistened with a light sweat, her convulsions grew stronger, and she reached climax repeatedly with only minimal thrusting. Additionally, through four experimental methods including "extreme orgasm denial" and "lustful herb inhalation," she experienced countless spasms and orgasms, ultimately being led into a trance state.
