Lure the exclusive actress 'Yatabe Kazusa' into unparalleled pleasure! This experiment, designed to make her climax repeatedly, verifies the effect of 'choking,' favored by about 30% of AV actresses. By heightening sensitivity through external clitoral massage or bondage and then inserting, the body immediately begins to convulse. Continuing to choke and piston causes the brain to secrete the pleasure hormone 'dopamine,' leading to intense, repeated orgasms. Additionally, experiments include extreme edging sex and the 4000-year-old Chinese secret technique 'Nine Shallow, One Deep,' experiencing countless convulsions and orgasms through four experiments, reaching a trance state!
