Kato Haruki, a 20-year-old insatiable B-type, makes her debut! A lustful woman who can climax endlessly during sex. She started masturbating at the age of three—an abnormally early bloomer—with an impulsive nature that swallows fists whole into her pussy. Her eyes roll back as she experiences overwhelming pleasure, leading to a shocking incident where an extremely thick fist insertion causes her small penis partner to rupture and bleed, depicted in a realistic, visceral experience. A vibrator is fully inserted deep into her uterus, triggering unknown waves of pleasure that make her sob and convulse uncontrollably. Pushing the essence of her deviant masochistic nature to the limit, she undergoes extreme genital torture training. This documentary-style film captures her genuine journey toward awakening the elusive P-spot pleasure—an authentic experience of pure ecstasy!
