Yesterday I was so excited I couldn't sleep... Hiyori, a 28-year-old housewife from Sendai. Her first experience was at 16, and before marriage she dated three boyfriends—all of them perverts. Through their influence, her deep-seated masochism gradually awakened, transforming her into a lustful wife who now enjoys masturbating with a vibrator. Thanks to years of perverted training, her body has become completely attuned to the pleasures of self-pleasure.
