"Saiyaka" was driven by insatiable desire, spending every day masturbating. However, one day her vagina spasmed and she couldn't remove the vibrator. In front of a young man who happened to be at her house, she ended up having an accidental squirt orgasm. Thus began their adulterous sex. With her lewd behavior on display, the married woman lost all inhibition and became addicted to penises other than her husband's, sucking and orgasming every day in a taboo act of internal ejaculation adultery.
