Shizuka Kanno is a genuine masochistic woman ranked number one in both beauty and deep insertion ability. A true pervert who has enjoyed inserting foreign objects into her genitals since middle school, her deviant nature is evident even during deep-throat acts. Though initially hesitant when encountering large toys for the first time, once she experiences the pleasure, she progressively welcomes them deeper inside. Her transformation is nothing short of becoming a true captive of ecstasy.
